These rituals are believed to strengthen the nation, and to ensure national prosperity and victory. Yet they consist largely of statements of rebellion against the king, by his brother-princes and by his subjects, and of affirmations that he is unworthy of his high office. She also brings out the smallness of the universe within which Swazi cosmology is established, and the particularistic nature of their answer to the problem, what is man? The world is seen as a setting for the Swazi, in competition with neighbouring nations, and not for humanity in general. The ceremony itself is strikingly an acting out of the whole of Swazi political relations, so that Dr. First, it reminds us that although the rituals Gluckman has been discussing are intended to strike the Western audience for whom the lecture was planned as exotic, the people performing them are dealing with fundamental issues that are faced by people everywhere; hence we should be able to think about similar rituals in our society. Second, Gluckman once again emphasizes that while the rituals have the appearance of rebellion, they are really nothing of the kind. In fact, they support the societies in which they are found and reproduce the same social forms they critique. But the rites affirm not only the unity of the nation about the kingship, but also all the conflicts around the person of the reigning king: the resentment of his subjects against authority, the jealousy of his brotherprinces who covet the throne, and so forth. Whether or not princes covet the throne they are made to act as if they do so covet it. At critical points when loyalty to the king is being affirmed, they have to leave the arena. And even their unborn children are also involved in the c o n f l i c t - f o r the pregnant wife of a prince must also withdraw. At particular points in the ceremony a black bull is required: these hulls are stolen from commoner subjects who are thus made "angry and proud, " say the S w a z i - a n apt description of the ambivalent attitudes involved in being a member of an authoritative nation. Here are typical songs: You hate the child king, You hate the child king; and You hate him, Mother, the enemies are the people. Like Gluckman, she studied anthropology at the University of Witwatersrand under A. Gluckman is trying to make his anthropology germane to the daily concerns of his audience. She was from Bulawayo in 198 You have wronged, Functionalism duties, and of privileges and powers as against responsibilities, the ritual enactment of the order states its rightness. The ritual states that in virtue of their social position princes and people hate the king, but nevertheless they support him. But these tendencies to fragment were canalized into a struggle to put particular princes on to the throne: the sections fought for the sacred kingship, and not for independence from it. Hence I have argued that in these African states periodic rebellions s t r e n g the n e d, and did not weaken, the political system. If this argument is acceptable, it is possible to see that the Swazi may be right when they say their great ceremony, so openly affirming conflicts, is a source of unity and s t r e n g t h - o f cohesion. It affirms the acceptance of kingship as such, as the source of law and moral order for the Swazi, against internal traitors and external foes. It does so by stating that those who are hostile to the ruling king, nevertheless support him because they support the kingship. Those who hate the king are those who reject him: enemies within the tribe, not external enemies, his brothers and his discontented subjects. His fate is sad because he carries the burden of office, and the hatred that is the lot of office. This theme of rejection and hatred of the king is so built into this great national ceremony that we have to ask, again, how the affirmation of rebellion can be so strong in a ritual which the people believe unifies and blesses their nation. And the king not only allows them to reject, and also to insult him; by doing so they are believed to support him in his arduous office. Obviously there may be high psychological catharsis and relief in the princes and subjects who are required thus publicly to express hidden resentments. But again, as a sociologist, I am interested in the fact that this affirmation of rebellion goes on within an accepted order. The kingship is sacred, and its sacred strength is necessary for the n a t i o n - n o t only for its political strength, but also for the fertility of its women, fields, and cattle. The acceptance of the established order as right and good, and even sacred, seems to allow unbridled licence, very rituals of rebellion, for the order itself keeps this rebellion within bounds. Hence to act the conflicts, whether directly or by inversion or in other sym bolical forms, emphasizes the social cohesion within which the conflicts exist. As the social order always contains a division of rights and " Note two ideas drawn directly from Durkheim in this passage: First, ritual is about social cohesion. Both Durkheim and Gluckman agree that the process has a great deal to do with the rituals that the society the Licence in Ritual, Max Gluckman m ay be pers on al ly i n a d e q u a t e, a n d may d e s e crate t he values of th e kingship, is ad m i t t e d in t he insults he suffers.

Fresh-cut rutabagas stored in 15% O2 will keep for 10 days at 10 °C (50 °F) and 20 days at 1 °C (34 °F) herbals that prevent pregnancy buy geriforte 100mg. The biological effects of sealed plastic containers by prepacked fresh fruit and vegetables wise woman herbals 1 generic geriforte 100 mg with visa. Acknowledgments Some of the information in this chapter is from the Agriculture Canada gayatri herbals buy geriforte pills in toronto, Canadian Food Inspection Agency website at. These greens may also be packed as bunches of leaves or plants (Rubatzky and Yamaguchi 1997, Pйron and Rees 1998). Precooling Conditions Greens for salads should be cooled to 0 °C (32 °F) as soon as possible after harvest. Rocket salad typically lasts 7 to 10 days and other leafy greens 10 to 14 days (Cantwell 1997). Scientific Names and Introduction Various greens other than lettuce are used in raw salads. Quality Characteristics and Criteria Greens used in raw salads must be fresh, tender, and turgid with no yellowing, decay, or insect or mechanical damage. Horticultural Maturity Indices Greens are harvested as individual leaves, leaf clusters, or whole plants and should be young, tender, and mild flavored. Plants that have flowered are usually too strong in flavor and tough in texture for use in raw salads. Chilling Sensitivity Salad greens are not sensitive to chilling and should be stored as cold as possible without freezing. Grades, Sizes, and Packaging these crops are not graded or sized in the United States. Salad greens may be packed in fiberboard cartons lined with perforated polyethylene bags 538 Ethylene Production and Sensitivity Salad greens have very low ethylene production but are highly sensitive to ethylene exposure (Cantwell 1997), which typically results in loss of chlorophyll leading to yellowing of leaves. Suitability as Fresh-Cut Product Intact leaves are sometimes included in packaged salad mixes. Respiration rates for other greens are not reported, but would be expected to be similar. Special Considerations Greens must be handled carefully to avoid mechanical damage and water loss. Postharvest Pathology Low temperatures must be maintained throughout the cold chain to minimize pathological disorders and prolong shelf-life. Salad greens are typically susceptible to the same bacterial soft rot and fungal decay as lettuce. A simplified procedure to determine the respiration rate of minimally processed vegetables in flexible permeable packaging. Grades, Sizes, and Packaging No official grades exist; sizing is based on length and diameter. Salsify is packaged in plastic liners or trays wrapped with plastic film to minimize water loss. The root is light yellow outside and white inside and 15 to 30 cm (6 to 12 in) long with a diameter of 2 to 2. Its taproot is larger, more cylindrical in shape, brown-black on the outside, and white inside. Both are rich in iron, vitamins (B1, B2, and E) and inulin, asparagin, and the glycoside laricin. Inulin is poorly digested by humans and can be used as a bulking ingredient in foods formulated with artificial sweeteners (see "Jerusalem Artichoke" chapter) and as a source of fructose (Kierstan 1978). In the absence of refrigeration, roots are also commonly stored in clamps (Hak 1993). Retail Outlet Display Considerations the skin is very delicate, and salsify easily loses water if not in plastic-lined trays. Horticultural Maturity Indices Harvest is based on root size and time from seeding-usually after 150 to 210 days. Ethylene Production and Sensitivity Salsify produces very little ethylene and has low sensitivity to ethylene. Wang, the Commercial Storage of Fruits, Vegetables, and Florist and Nursery Stocks, p. Production of fructose syrups from inulin-containing plants [Jerusalem artichokes, chicory, salsify extracts]. Suitability as Fresh-Cut Product Salsify is not currently marketed as fresh-cut product.

It has a low water content (64 to 72%) and higher amounts of riboflavin, niacin, and ascorbate than apples or bananas (Wenkam and Miller 1965, Lopez 1984). This chapter discusses black sapote, lucuma, mamey apple, sapodilla, sapote, star apple, and white sapote. Horticultural Maturity Indices the maturity index commonly used is a change of peel color from green to yellow. However, variability exists in peel and pulp color, ranging from green to yellowish-green peel and lightyellow to orange-yellow pulp (Lizana 1980). The classes in relation to peel and pulp color are- Class Peel color Pulp color 1 light-yellow light-yellow 2 light-green creamy-yellow 3 yellow-green yellow 4 green-yellow dark-yellow 5 green-yellow orange-yellow Fruit ripened on the tree usually become soft and very fragile (Lizana 1980). Intense respiratory activity and sugar accumulation occur during ripening (Lizana et al. Optimum Storage Conditions and Chilling Sensitivity Black sapote is chilling sensitive. Fruit held at 15, 20, or 25 °C (59, 68, or 77 °F) for up to 7, 10, or 15 days and then transferred to 25 °C (77 °F) ripened normally (Miller et al. Fruit held at 10 °C (50 °F) for 7 days and then transferred to 25 °C (77 °F) also ripened normally. However, some fruit held at 10 °C (50 °F) for 10 or 15 days showed abnormal ripening, and most fruit stored at 1 to 5 °C (34 to 41 °F) did not ripen normally or failed to ripen regardless of storage duration. Mamey Apple Scientific Name and Introduction Mamey apple, also know as mamey and zapote, (Mammea americana) is a fruit of about 300 to 500 g having a peachlike flavor. The fruit is a drupe about the shape and size of an orange, with a russet surface covered with small spots. It is round with a thick, brown, leathery skin containing one large single seed surrounded by a thin layer of flesh. The flesh, or endocarp, is yellow, about 2 to 5 mm thick, and fused with the testa. It weighs about 70 to 300 g and has a dull brown color, thin skin, and yellowish, light brown, or red pulp. Horticultural Maturity Indices the erratic flowering habit of sapodilla and the presence of fruit at all stages of development on the tree make it difficult to determine optimum harvest time (Lakshminarayana 1980). Fruit harvested later than optimum time usually soften very rapidly and become very difficult to handle. Fruit harvested earlier than physiological maturity may not soften, are usually low in sweetness and high in astringency when ripe with a rather unappealing alcoholic aftertaste, and form pockets of coagulated latex that lower quality.

Corticosteroids are considered to herbs mopar purchase geriforte 100mg fast delivery be the most effective method to shivalik herbals order geriforte 100 mg overnight delivery achieve long-term control of asthma just herbals purchase discount geriforte online. These anti-inflammatory agents reduce airway hyperresponsiveness, inhibit inflammatory cell migration and activation, and block late-phase reaction to allergens (National Heart, Lung and Blood Institute, 2007). Inhaled corticosteroids are the most consistently effective at all steps of care for persistent asthma. Oral corticosteroids may be used to gain prompt control of asthma and are required for severe persistent asthma (see Tables 167 and 16-10). These antiinflammatory agents inhibit activation and release of mediators from mast cells, thus maintaining airway stability. Immunomodulators (omalizumab) is a monoclonal antibody given intramuscularly to prevent binding of IgE to the high-affinity receptors on basophils and mast cells (National Heart, Lung and Blood Institute, 2007). This is used an adjunctive therapy for children 12 years and older who have demonstrated sensitivity to specific allergens and who require a step up in care to manage their persistent asthma. Leukotriene modifiers are used for children requiring step 2 care for mild persistent asthma. These products interfere with the pathway of leukotriene mediators that are released from mast cells, eosinophils, and basophils (National Heart, Lung and Blood Institute, 2007). Long-acting beta2 agonists such as salmeterol and formoterol are bronchodilators that open the airways by relaxing smooth muscle contraction and reducing bronchospasm, which thereby enhances mucociliary clearance and decreases vascular permeability. Methylxanthine is a sustained-release theophylline that has some mild antiinflammatory effects and can be used as adjunctive therapy with inhaled corticosteroids for children older than 5 years. For a more detailed description of these medications and their recommended use, dose, adverse effects, and care concerns, please refer to the National Heart, Lung and Blood Institute (2007) asthma guidelines. Medications are also used to provide quick relief for acute symptoms and exacerbations. These acute symptoms may be brought on by environmental exposures (as described earlier) or perhaps by exercise-induced bronchospasm that was not effectively managed by the medications previously described to step up or down care for long-term asthma control. These agents inhibit muscarinic cholinergic receptors and reduce the intrinsic vagal tone of the airways (National Heart, Lung and Blood Institute, 2007). Determine the medications the child is using and whether any complimentary and alternative medications or treatments (chiropractic medicine, acupuncture) are be used. There is insufficient evidence to support recommending the use of complimentary and alternative medications for treatment of allergy. Families who use herbal treatments for asthma should be cautioned about the interactions that some of the ingredients may have with their prescribed asthma medications. Ask to view any records the child has been keeping of his or her symptoms and/or peak flow monitoring. Advise children with moderate or severe persistent asthma to keep daily peak flow monitoring records. These tools will aid the child and family to recognize adequate and inadequate asthma control. Although the steps in this process seem easy, incorrect use of the inhaler means less medication is getting to the airways. Provide instruction materials and for sample peak flow charts to the family (see Procedures: Use and Care of Peak Flow Meters and Spacers). An acute or subacute episode of asthma is identified as progressive and worsening shortness of breath, cough, wheezing, and/or chest tightness. These symptoms indicate decreases in expiratory airflow and require immediate intervention. Children whose asthma has been well controlled using inhaled corticosteroids are less likely to have an exacerbation; however, all children are at risk for exacerbations. Respiratory infections, exercise-induced bronchospasm, extreme changes in weather, exposure to a known (or unknown) allergen, and stress can precipitate a worsening of asthma symptoms. Remove or withdraw the child from allergens in the environment that may be contributing to the exacerbation. For acute exacerbation that responds poorly to initial interventions, or when ongoing observation and stabilization of the child is needed, hospitalization may be indicated. If the child is becoming less alert or drowsy, this may indicate impending respiratory failure. Endotracheal intubation and assisted ventilation must be considered if steady clinical deterioration occurs despite continued intensive therapy. If he continues in respiratory distress, despite his initial treatments, oxygen will be administered. This condition is seen predominantly in infants born prematurely (more than 10 weeks before their due date), infants less than 1,000 g at birth, and in infants with multiple pulmonary disorders who require ventilator support with high positive airway pressures and oxygen during the first 2 weeks of life. The epithelium of the conducting airways develops lesions from injury thought to be related to hyperoxia and positive pressure. Excessive pulmonary fluid, collection of cellular debris in the alveoli, and recurrent bacterial and viral infections are additional factors contributing to the alveolar tissue damage. These factors include fibrosis of the airways and marked hyperplasia of the bronchial epithelium, which occur secondary to alveolar damage; and increased fluid in the lung, as a result of disruption of the alveolarcapillary membrane. Damage to the alveolar supporting structures results in overdistension and leads to air trapping, fibrosis, airway edema, and bronchoconstriction, increasing airway resistance and decreasing compliance. Increased airway resistance increases the work of breathing, resulting in tachypnea and wheezing. Hypoxia occurs secondary to ventilationperfusion mismatch in the areas of alveolar collapse. Increased pulmonary vascular resistance causes intrapulmonic shunting, thus also contributing to hypoxia. Hypercarbia is common and is also caused by ventilationperfusion mismatch, as well as by hypoventilation. Both tracheomalacia and bronchomalacia are commonly found in this population and Community Care the National Heart, Lung and Blood Institute (2007) asthma guidelines represent the best evidence to date regarding the assessment, monitoring, and management of asthma. Surveillance of environmental triggers must also occur in all settings (home, school, daycare, and so forth) in which the child is likely to spend time. Although timing of diagnosis varies, the clinical diagnosis is generally made at approximately 1 month of age in infants who required mechanical ventilation for at least 1 week; have symptoms of persistent respiratory distress; are dependent on supplemental oxygen; and have chest radiographs that show hyperinflation, atelectasis, increased density, and fibrotic areas (American Thoracic Society, 2003). Growth failure and lung disease may also be complicated by gastroesophageal reflux with frequent emesis, poor oral feeding skills, and recurrent respiratory infections (Huysman et al. The pulmonary vasculature of these infants develops increased reactivity to hypoxia, resulting in pulmonary hypertension and left ventricular hypertrophy with congestive heart failure. High-frequency oscillatory ventilation delivers gas at extremely high frequencies (>200 ``breaths'/minute) and considerably lower pressures than those used for standard mechanical ventilation, thus reducing barotrauma to the alveoli. Studies have shown that surfactant therapy reduces the severity of respiratory distress syndrome and decreases the amount of time on mechanical ventilation.

Neomaterialism: Evolutionary, Functionalist, Ecological, and Marxist 1 Lilian Steward and Leslie White set the stage for ecological anthropology and materialist cultural analysis, but it was the next generation of anthropologists who really developed these fields of inquiry. By midcentury, two types of materialism were becoming popular in anthropology: ecological-materialist approaches and neo-Marxist approaches. The ecological-materialist approach to anthropology was heavily influenced by general systems theory and the growing science of ecology (Orlove 1980). They commonly assumed that societies were homeostatic, that is, that cultural institutions functioned as feedback mechanisms (like thermostats) to maintain a balance between energy production and expenditure and the productive capacity of the environment. Typically, ecological materialists examined culture using an equilibrium model that traced energy flow within an ecosystem. For example, a society might be analyzed in terms of its food production and the caloric expenditure of human energy required to maintain the society in equilibrium. In addition, ecological-materialist studies differed from those of Steward and White in that the former tended to take local populations rather than cultures as their units of analysis. Ecological materialists examined the interactions between populations and environments rather than treating the environment as a passive background that shapes culture but is not influenced by it. Ecological materialism can be subdivided into two different approaches: neoevolutionism and neofunctionalism (Orlove 1980). Like Lewis Henry Morgan (see essay 3), neoevolutionists were primarily interested in the origins of cultural phenomena and in particular, the rise of civilization. For instance, the famous bands-tribes-chiefdoms-states sequence of cultural development was proposed by Service (1962), a student of both White and Steward. He was deeply affected by classes he took from Julian Steward as well as by his fellow students, including Elman Service, Stanley Diamond (1922-1991), Eric Wolf (1923-1999), and Robert Manners (1913-1996). Gordon Childe with making major contributions to his understanding of social evolution (Service 1988). In the essay presented here, Fried examines the evolution of social stratification in relation to the control and distribution of resources, a perspective he develops more fully in the Evolution 265 266 Neomaterialism: Evolutionary, Functionalist, Ecological, and Marxist wrote that Americans have "been taught to value elaborate "spiritualized" explanations of cultural phenomena. What I mean by a banal or vulgar solution is that it rests on the ground and that it is built up out of guts, sex, energy, wind, rain, and other palpable and ordinary phenomena. In addition to copious work designed for professional consumption, Harris also wrote many books for popular audiences, including Cows, Pigs, Wars and Witches: the Riddles of Culture (1974), Cannibals and Kings: the Origins of Culture (1977), Good to Eat: Riddles of Food and Culture (1985), and many others. These books, which give cultural-materialist explanations of cultural phenomena, are written in an extremely accessible and engaging style and had enormous popular success. Cultural-materialist analysis was extremely popular in the 1970s and 1980s and continues to command a large following today. However, it is also frequently attacked as naive positivism, " rooted in a mechanical, naturalistic mode that fails to reckon with the fact that the mind is more than a tabula rasa" (Murphy 1994:58). Harris vehemently resisted such charges, while insisting that an objective, positivist science of society is not only possible but necessary. His position is perhaps best summed up in the title of one of his essays, "Cultural Materialism Is Alive of Political Society There, Fried examined the development of social inequality, proposing the evolutionary stages of egalitarian, ranked, stratified, and state societies. Like the psychological and structural functionalists of the first half of the twentieth century, neofunctionalists were interested in the function and purpose of institutions and beliefs. However, whereas the functionalists described institutions in terms of their contribution to individual needs or social stability, neofunctionalists were interested in adaptation. They focused on the ways in which particular cultural beliefs, practices, and institutions allowed populations to maintain and reproduce themselves successfully within specific physical, political, and economic environments. The dominant perspective within neofunctionalism is called cultural materialism, and Marvin Harris (1927-2001) was its leading proponent. Harris did both his undergraduate and graduate training at Columbia University, where he also served as a professor from 1953 to 1980. His experiences of Portuguese colonialism there convinced him that systems of production were fundamental to any understanding of culture (Harris: 1994:75-76). Marx (see essay 4) believed that production played the primary role in social evolution, influencing the sociological and ideological levels of society. While rejecting Marxist dialectics, cultural materialists firmly insist on the primacy of modes of production and reproduction-what Harris (1979) called " infrastructure"- i n determining behaviors and beliefs within a society. He convincingly demonstrates the material and ecological importance of cattle to Indian society and argues that this, rather than Hindu religious doctrine, is the ultimate basis of the ban on killing and eating cattle. A second orientation in neofunctionalist materialism comes from the work of Roy Rappaport (1926-1997). Whereas Fried and Harris drew their inspiration from Marx, Rappaport was more deeply affected by the work of ecological biologists. His deep reading in biological ecology led to doing research for his dissertation under Andrew P. Rappaport and Vayda believed that general laws of biological ecology could be used to study human populations, a belief they sought to substantiate in their fieldwork.

Tubers are delivered to herbalsmokecafecom cheapest generic geriforte uk processing plants in bulk trucks or bins holding about 2,000 lb (910 kg). Scientific Name and Introduction the white, or Irish, potato, Solanum tuberosum L. The edible portion is the tuber, an underground stem that forms at the end of stolons. It is native to the Americas, with many close relatives in the Andean region of South America. New varieties commonly have one or more wild Solanum species included in their pedigree. Potato is grown throughout the world in temperate zones, with planting in spring and harvest in fall. There are many skin colors (brown russet, white, red, pink, yellow) and flesh colors (white, cream, yellow, blue/purple/red, and striated). Stored potatoes are available year-round; fresh potatoes are harvested year-round, albeit in small quantities during winter, spring, and summer. Quality Characteristics and Criteria A high-quality fresh-market potato tuber is turgid, well shaped, uniform, and brightly colored (especially reds, whites, and yellows), as well as free from adhering soil, mechanical damage, greening, sprouts, diseases, and physiological defects. Horticultural Maturity Indices the ability of potato tuber skin to resist abrasion (skinning) during harvest is a common index for maturity. Sugar content is a maturity index for processing potatoes, with both immaturity and 506 Optimum Storage Conditions Long-term storage of potato tubers-up to 12 mo-requires that they be cured. Frequently, potatoes harvested in fall in temperate climates are colder than the optimal curing temperatures. In some cases, two additional steps must be employed: drying of wet potatoes upon entry into storage, and heating of tubers before removal from storage. Forced movement of air is used to ensure uniform temperature throughout the storage pile. Storage at 0 to 2 °C (32 to 36 °F) increases the risk of freezing or chilling injury. Sprouting accelerates at temperatures >4 °C (40 °F), so seed tubers are commonly stored at 4 to 5 °C (40 °F). Tubers for fresh consumption are stored at 7 to 10 °C (45 to 50 °F), to minimize conversion of non-reducing sugars such as starch to reducing sugars such as glucose, which darken during cooking. Tubers for frying are stored at 10 to 15 °C (50 to 59 °F), depending on the cultivar and its respective sugar conversion characteristics. Thus, chipping cultivars are stored at 15 to 20 °C (59 to 68 °F); new cultivars are being developed that will not accumulate sugar at temperatures as low as 5 to 10 °C (41 to 50 °F). Quality tubers can be stored for 2 to 12 mo, depending on quality at harvest, quality of storage facilities, variety, and whether or not sprout inhibitors are used. Sprout inhibitor may be applied in the field before senescence begins, on the tubers as they are graded and packaged, or in storage after curing is completed. Retail Outlet Display Considerations Cured and new potatoes, whether displayed in bulk or in cellophane or paper bags are displayed dry. New potatoes that are displayed in bulk are commonly included with other cool-season vegetables that receive periodic water misting or sprinkling. Internal mahogany browning can occur at 1 to 2 °C (34 to 36 °F), while temperatures of 3 to 4 °C (37 to 39 °F) typically result in increased reducing sugar levels that are not reversible with reconditioning. Ethylene Production and Sensitivity Potatoes produce very low levels of ethylene: <0. Low levels of ethylene elevate respiration, especially in immature potatoes, and result in weight loss and 507 mild shriveling. After 2 to 3 mo at >5 °C (41 °F) without sprout inhibitor, low levels of ethylene may retard sprouting, while high amounts may induce sprouting. Respiration Rates Immature potato tubers usually have higher respiration rates than mature or cured tubers. Cooler temperatures and increased air movement are effective at controlling effects of a high rate of respiration. If air exchange around tubers is insufficient, low-O2 conditions develop in the interior of the tuber, and the cells suffocate and turn black. Freezing at -1 °C (30 °F), whether in the field or in storage, typically results in a distinct demarcation between affected and unaffected tissue. Symptoms include a water-soaked appearance, glassiness, and tissue breakdown on thawing. Chilling injury can occur after a few weeks at 0 °C (32 °F) and result in a mahogany discoloration of internal tissue in some varieties. Affected tubers are easily culled at grading and rarely proceed to marketing channels. Darkness is essential for long-term storage because greening can occur during storage or marketing. Exposure to bright light during postharvest handling, or longer periods (1 to 2 weeks) of low light, can result in development of chlorophyll (greening) and bitter, toxic glycoalkaloids such as solanine. Solanine also forms in response to bruising and wounding (including fresh processing followed by storage) and during sprouting. Tubers in market displays should be replaced daily or more frequently to minimize greening. Enlarged lenticels are a common disorder in early potatoes where excessive irrigation is often applied to maintain cooler soil temperatures in warm or hot climates. These lenticels are subject to pathological infection in the soil or during packing. Infections may remain innocuous; or if transportation conditions are not properly maintained, they can increase rapidly in severity. Tubers that appear sound at the packing shed can become unmarketable during transit. Physiological Disorders the most common and serious physiological disorders affecting potatoes include black spot, blackheart, freezing injury, greening, hollow heart, sugar end browning, and internal necrosis. Black spot results from a physical impact to the tuber; the stem end is most sensitive. Following severe bruising or cutting, the affected tissue turns reddish, then blue, becoming black in 24 to 72 h. Soil conditions can predispose tubers to blackspot; poor aeration is the most common cause. Cultivars vary in ability to set-skin, in skin thickness, and thus in skinning susceptibility.

Fill material shall have a permeability similar to baikal herbals cheapest geriforte but not more permeable than the underlying in-situ useable soil rm herbals buy geriforte 100 mg on line. The depth of fill material herbals aarogya order geriforte paypal, including the topsoil layer, shall not exceed 30 inches above the original ground elevation. A conventional absorption trench system as depicted in Figure 17 and Figure 24 is designed and constructed in the fill and into original soil. The required length of absorption trench shall be determined from Table 6A or Table 6B based upon the daily design flow rate and percolation test results of the in-situ permeable soil. Percolation test results of the fill material (foundation spoils or borrow pit soils) shall be used to assure that the permeability of the fill material is compatible with the in-situ soil permeability. In areas, which are suitable, all trees and stumps shall be cut at grade and removed. Other vegetation (brush, vines, weeds, grass) shall be cut as close to grade as possible and removed. Plowing the area where fill is to be placed "folds" soil over without destroying the soil structure and infiltration capability of the receiving soils. Rototilling or soil scarification should never be performed in the fill area by heavy construction equipment because of the probability of destroying the soil structure, compacting soils and reducing the infiltration capability. Grade stakes may be used to delineate the limits of fill and prevent over-excavation of absorption trenches. The edge of the fill material shall be extended at least six (6) feet beyond the perimeter of the proposed trenches and then tapered at a slope no greater than one (1) vertical to three (3) horizontal. On sloped sites, a diversion ditch or berm shall be constructed on the uphill side of the fill material to prevent surface runoff from entering the fill. Construction of trenches at least six (6) inches into existing in situ soil is preferred to utilize a stabilized sidewall infiltrative surface. These systems are generally used where the impermeable overlaying soil is one (1) to five (5) feet deep. Conventional absorption field systems may be used when the overlaying impermeable soil is no more than one (1) foot deep and useable soil is placed above the aggregate. For cut and fill system, unlike deep absorption trench systems, the overlaying impermeable soil is removed from the proposed absorption field area that extends at least five (5) feel beyond any proposed absorption trenches and replaced by permeable soil comparable to the underlying soil. Careful excavation is necessary to assure that the useable underlying soil is not made unuseable through compaction and impermeable overburden does not remain in the bottom of the excavation on top of the permeable underlying soil. A conventional absorption trench system is constructed in the upper 18 to 30 inches of the permeable fill and underlying soil. If the bottom of all trenches is not in or at the permeable underlying soil (meaning the trench bottoms are in fill), the fill must undergo proper stabilization and percolation testing prior to constructing the trenches. Stabilization may be achieved by natural settlement for at least six (6) months including at least one (1) freeze-thaw cycle. If the underlying permeable soil and the comparable permeable fill comprise only granular material (sand and sandy loam), stabilization may be achieved by mechanical compaction in six (6) inch lifts to the approximate density of the undisturbed underlying granular soil. On sloped sites, a diversion ditch or berm shall be constructed on the uphill side of the fill area to prevent entrance of surface runoff. Although deep trench systems may be used at sites with four (4) feet of useable soil overlaid by one (1) to five (5) feet of impermeable soil, a cut and fill system is the recommended choice because shallow trenches and permeable fill material provide an improved treatment environment through better oxygen exchange and increased infiltrative soil surface area (aggregate to permeable soil interface). The excavation method selected should assure that the useable underlying soil is not made un-useable through compaction. A conventional absorption trench system as depicted in Figures 17 and 25 is designed for the upper 18 to 30 inches of the permeable fill and underlying soil. The required length of absorption trench shall be determined from Tables 6A or 6B based upon the daily design flow rate and percolation test results of the permeable fill or underlying soil (whichever has the lower permeability). Stabilization of the fill is required prior to conducting percolation tests and constructing trenches if the bottoms of all trenches are not in or at the underlying useable soil. Percolation test results of the fill material performed at the borrow pit shall be used to assure that the permeability of the fill material is compatible with the on-site soil permeability. The soil placed above the trenches shall have a percolation rate faster than sixty (60) minutes per inch. Original surface material (the overlaying impermeable soil) shall not be used as backfill above the trenches. The surface area of the fill system must be mounded and graded to enhance runoff of precipitation from the absorption system and seeded to grass. On sloped sites, a diversion ditch or berm shall be constructed on the uphill side of the absorption area to prevent surface runoff from entering the fill. This, however, reduces the effective sidewall infiltration area per lineal foot of lateral. These systems require the use of pressure distribution or siphon dosing (when slope permits) and are limited to sites with a maximum slope of 8% and at least four (4) feet of useable soil with a percolation rate of one (1) to thirty (30) minutes per inch. Careful excavation is necessary to assure that the bottom and sidewall areas are not made unuseable through compaction. Heavy construction equipment shall be kept outside the proposed bottom area of the absorption bed. Diversion of surface runoff around the absorption bed area by means of ditches or berms is required uphill on all sloped sites. Bed width on sloped sites should be minimized to maximize wastewater distribution parallel to the slope and to prevent ends of the bed from being too deep or too shallow. Bed systems are more practical on sites that are long (parallel to ground contours), narrow and with a minimal slope. All minimum vertical and horizontal separation distances noted in Figure 1, Figure 18, Figure 26 and Table 2 shall be met. The maximum length of each lateral for a pressure manifold shall be 100 feet and for a siphon or pump dosing system shall be 75 feet. The depth of the absorption bed shall be between 18 and 30 inches below original ground level (as measured at the midpoint of the width of the bed). Distribution laterals shall be spaced a maximum of five (5) feet center to center. The maximum absorption bed size is 20 feet wide by 205 feet long for pressure distribution with a center manifold and 155 feet long for pump or siphon dosing with a center manifold. The maximum bed size is 20 feet wide by 105 feet long for pressure distribution with an end manifold and 80 feet long for pump or siphon dosing with an end manifold. Pressure distribution lines should be one (1) inch to three (3) inches in diameter with all downstream ends capped or looped. The volume discharged during each cycle of a pressure distribution system will exceed the volume available in the pipe distribution network and will be discharged from the pipe under pressure. Pumps for the pressure distribution system should be designed to provide one (1) 71 Chapter 9: Subsurface Onsite Wastewater Treatment Systems pound per square inch (2. Pipe for siphon dosing is sized to conform to the volume of the dose and can range from three (3) to six (6) inches in diameter based upon the volume of each dose. The volume discharged during each cycle of a pump or siphon dosing system should be 75% to 85% of the volume available in the pipe distribution network or three (3) to five (5) times per day based upon daily design flow volumes, whichever is smaller. The required bed bottom areas for standard daily design flows are listed in Table 7A or can be calculated for non-standard daily design flows using the application rates listed in Table 7B. Heavy construction equipment shall be kept outside the proposed bottom area of the bed to avoid compaction of the soil.

Blue-green algae dominant at 40-60°C include species of Mastigocladus (Stewart zee herbals buy cheap geriforte 100 mg online, 1975) herbals in american diets buy generic geriforte 100 mg on line. In hot springs in Japan herbals in the philippines order geriforte without a prescription, potential nitrogen-fixing species of Anabaena Calothrix Cylindrospermum, Hapalosiphon, Mastigocladus, Nostoc and Scytonema all occur at temperatures ranging from 30-50°C. At the low temperature extreme, in the Antarctic, blue-green algae are abundant, and the most common genera in this habitat are Nostoc, Scytonema hofmanni, Anacystis and Coccochloris. HapaZosiphon fontinalis, Anabaena variabilis and Calothrix elenkinii grew at pH 7. Nitrogen-fixation by Nostoc and Collema in Antarctica is greatly affected by the snow-free seasons and desiccation. In the hot deserts of America, blue-green algae occur particularly in any puddled areas, in intermittent streams and transitory pools, in lichen symbiosis and under pebbles, stones and rocks. In temperate regions, in situ rates of nitrogen-fixation by Nostoc in sand -d une ecosystems were found to be much higher in areas shaded by long grass than in more open, desiccated areas (Stewart, 1965). Singh (1961) reported that in Indian paddy soils the redox potential of the soil stabilises on the reducing side at the time of puddling, and then thick growths of blue-green algae develope. Pesticides Pesticides commonly used in agriculture may or may not affect the growth of blue-green algae, depending on the type, concentration and time of application of the compound. On the other hand Hamdi et al (1970) evaluated the effect of the herbicides molinate, propanil, trifluralin and 2,4-D. Chlorophyll synthesis was stimulated by low levels of molinate, trifluralin and 2,4-D in both treatments but was inhibited by propanil. Venkataraman and Rajyalakshimir (1971,1972) also examined the effect of various pesticides. They found that while most of the strains of Anabaena could tolerate 100 ppm of "Ceresan M" a few were sensitive to a concentration as low as 0. The variability in algal population from field to field and the sudden disappearance of algae are generally attributable to attack by these organisms. The chytrids and bacteria (Myxobacteria, Cytophaga) are found in many habitats and laboratory work has shown that they can infect algal lawns to plague proportions. Daff, Begg and Stewart (1970) isolated a virus pathogenic to Plectonema, Phormidium and Lyngbya from a variety of fresh waters in Scotland. Blue-green algal viruses from rice fields in India have been studied in detail (Singh and Singh, 1967). Hof and Fahmy in 1933 (Fogg et al, 1973) divided the algae into two physiological groups: halotolerant and halophilic. For example a halotolerant species is Calothrix scopulorum,while an example of a halophilic species is Spirulina subsalo. El-Nawawy et al (1968) reported that the fixation of atmospheric nitrogen by the local strain of blue-green alga, Calothrix sp was slightly affected by 1 747. However, concentrations of 795 and 1 590 ppm had no influence on the nitrogen-fixation of the alga. Growth of the alga was not affected appreciably until the highest concentration of 4 191. Khadr (1975) showed that growth of Nostoc calcicola increased as a result of increasing the sodium chloride concentration up to 9 000 ppm after which it began to decline. Growth of Anabaena variabilis was slightly increased by 9000 ppm of sodium chloride but it was markedly decreased by 12 000 and 15 000 ppm. Growth of Anabaena oryzae and Nostoc muscorum significantly decreased at 21 000 ppm and the same concentration of sodium chloride was lethal to Anabaena naviculoides. Brock (1976) isolated the halophilic blue-green alga Aphanothece halophytica from the Great Salt Lake in Utah,U. The optimum salinity for growth of this organism was found to be about 16% of sodium chloride, but it could grow very slowly even in a saturated (30%) solution. Table 21 summarizes some of the available data on the amounts of nitrogen fixed in culture media. Under Field Conditions Various reports indicate that there is an increase in the nitrogen content of the soil through algal inoculation. Sankaram (1971) showed a gradual increase in the organic matter content due to algal inoculation, although the increase was small (Table 22). When the soils were fertilized with phosphorus, the amount of nitrogen fixed was calculated to be 18-69 kg N/ha during the same period. Watenabe et al, (1951) reported nitrogen-fixation by Tolypothrix tenuis inoculated in rice fields in Japan to be about 22 kg N/ha. Granhall (1976) reported data on in situ nitrogen-fixation rates in Swedish soils near Uppsala by a 0-2 cm layer of blue-green algae. Clay soils were among the most suitable habitats for blue-green algae and the environmental factors. Heterotrophic fixation by bacteria, as judged from samples kept in the dark for 24 hr, was sometimes observed and varied between 0. Many reports also indicate that a variety of organic compounds are liberated (Stewart, 1975). Studies on symbiotic systems have shown clearly that the nitrogen fixed by blue-green algae is rapidly transferred to the host. Bergersen et al (1965) have shown that nitrogen fixed in cycads appeared in all parts of the plants within 48 hours. Pot and field experiments have shown that the nitrogen fixed by bluegreen algae becomes available to associated rice plants, which results in increased crop yield. In addition to vitamins, the algae produce auxin-like growth substances; and considerable amounts of ascorbic acid (Vaidya et al, 1970). The algae liberate these substances either by excretion or autolysis into the surrounding medium, from which the crop plants can assimilate them. The following are summaries of the techniques used by various workers for the production of blue-green algae biomass. Preliminary shake culture the alga from agar slants was transferred to round flasks which were constantly shaken at 32°C. The cultures were illuminated by incandescent lamps set in the inner wall of the incubator. The tank was a 30 litre pyrex glass cylinder housed in a water bath thermostatically controlled at 32°C. The water bath was provided with three windows for illuminating the culture from outside. The carbon dioxide enriched air (3%) was bubbled at a rate of 350 ml/min into the culture solution. A rubber tipped wiper was also provided to detach the alga from the walls of the glass cylinder. Prior to inoculation, the chamber and the culture medium were sterilized with steam for 15 min at 0. Closed circulation system For outdoor culture, the culture chamber was made of a long flat polyvinyl bag of 300 litre capacity, the two ends of which were connected with each other through a 3 cm diameter and 8 m long tube.

Furthermore, in the area occupied by the Maring speakers, more than one local group is usually involved in any process, either peaceful or warlike, through which people are redistributed over land and land redistributed among people. The concept of the ecosystem, though it provides a convenient frame for the analysis of interspecific trophic exchanges taking place within limited geographical areas, does not comfortably accommodate intraspecific exchanges taking place over wider geographic areas. Some sort of geographic population model would be more useful for the analysis of the relationship of the local ecological population to the larger regional population of which it is a part, but we lack even a set of appropriate terms for such a model. Suffice it here to note that the relations of the Tsembaga to the total of other local human populations in their vicinity are similar to the relations of local aggregates of other animals to the totality of their species occupying broader and more or less continuous regions. This larger, more inclusive aggregate may resemble what geneticists mean by the term population, that is, an aggregate of interbreeding organisms persisting through an indefinite number of generations 8 and either living or capable of living in isolation from similar aggregates of the same species. This is the unit which survives through long periods of time while its local ecological (sensu stricto)8 subunits, the units more or less independently involved in interspecific trophic exchanges such as the Tsembaga, are ephemeral. Since it has been asserted that the ritual cycles of the Tsembaga regulate relationships within what may be regarded as a complex system, it is necessary, before proceeding to the ritual cycle itself, to describe briefly, and where possible in quantitative terms, some aspects of the place of the Tsembaga in this system. Two named garden types are, however, distinguished by the crops which predominate in them. I estimated that approximately 310,000 calories per acre is expended on cutting, fencing, planting, maintaining, harvesting, and walking to and from taro-yam gardens. Sugar-sweet potato gardens required an expenditure of approximately 290,000 calories per acre. On the basis of daily consumption records kept for ten Sensu stricto: Latin for strictly speaking. Within this framework, he discusses the Tsembaga as calorie producers and consumers. Other cultural features arise as a result of this core or are historically particular and of less analytic importance. The area in secondary forest comprises approximately 1,000 acres, only 30 to 50 of which are in cultivation at any time. Assuming calories to be the limiting factor, and assuming an unchanging population structure, the territory could support-with no reduction in lengths of fallow and without cutting into the virgin forest from which the Tsembaga extract many important i t e m s b e t w e e n 290 and 397 people if the pig population remained minimal. Taking Maring pig husbandry procedures into consideration, I have estimated the human carrying capacity 13 of the Tsembaga territory at between 270 and 320 people. Because the timing of the ritual cycle is bound up with the demography of the pig herd, the place of the pig in Tsembaga adaptation must be examined. Second, months on four households numbering in total six-teen persons, I estimated the average daily intake of adult males to be approximately 2,600 calories, and that of adult females to be around 2,200 calories. Although 99 percent by weight of the food consumed is vegetable, the protein intake is high by New Guinea standards. The daily protein consumption of adult males from vegetable sources was estimated to be between 43 and 55 grams, of adult females 36 to 48 grams. The same is true of the younger age categories, al-though soft and discolored hair, a symptom of protein deficiency, was noted in a few children. Despite the small numbers, it should be noted that, at the time this essay was published, it was probably the most detailed and comprehensive body of data ever collected on swidden agriculturalists. In keeping with the biological model on which he based this work, all of the data is available for inspection in the appendices to Pigs for the Ancestors (1967). Further, for Marxists, conflict drives progressive change, but for Rappaport, conflict is a feature that returns the cultural system to a state of equilibrium. Rappaport again uses a concept borrowed from biology-carrying capacity, which is the number of indi 13 12 viduals of a species that a given ecosystem can support without suffering degradation. Notice that for humans, the technology of food production must be taken into account, a point also discussed by Steward. Once there, his experiences compelled him to take a position in some ways more extreme than these classic cultural ecologists. Steward had supposed that, though environment had a profound impact on human society, humans were, in fundamental ways, so different from other creatures that natural laws that applied to populations of other animals could not be applied to them. Rappaport 301 limited numbers of pigs rooting in secondary growth may help to hasten the development of that growth. The Tsembaga usually permit pigs to enter their gardens one and a half to two years after planting, by which time second-growth trees are well established there. The Tsembaga practice selective weeding; from the time the garden is planted, herbaceous species are removed, but tree species are allowed to remain. By the time crop-ping is discontinued and the pigs are let in, some of the trees in the garden are already ten to fifteen feet tall. These wellestablished trees are relatively impervious to damage by the pigs, which, in rooting for seeds and remaining tubers, eliminate many seeds and seedlings that, if allowed to develop, would provide some competition for the established trees. Moreover, in some Maringspeaking areas swiddens are planted twice, al-though this is not the case with the Tsembaga. After the first crop is almost exhausted, pigs are penned in the garden, where their rooting eliminates weeds and softens the ground, making the task of planting for a second time easier. They run free during the day and return home at night to receive their ration of garbage and substandard tubers, particularly sweet potatoes. Supplying the latter requires little extra work, for the substandard tubers are taken from the ground in the course of harvesting the daily ration for humans. Daily consumption records kept over a period of some months show that the ration of tubers received by the pigs approximates in weight that consumed by adult humans, i. If the pig herd grows large, however, the substandard tubers incidentally obtained in the course of harvesting for human needs become insufficient, and it becomes necessary to harvest especially for the pigs. In other words, people must work for the pigs and perhaps even supply them with food fit for human consumption. Thus, as Vayda, Leeds, and Smith (1961:71) have pointed out, there can be too many pigs for a given community. A small number of pigs is sufficient to keep residential areas clean, to suppress superfluous seedlings in abandoned gardens, and to soften the soil in gardens scheduled for second plantings. A larger herd, on the other hand, may be troublesome; the larger the number of pigs, the greater the possibility of their invasion of producing gardens, with concomitant damage not only to crops and young secondary growth but also to the relations between the pig owners and garden owners. All male pigs are castrated at approximately three months of age, for boars, people say, are dangerous and do not grow as large as barrows. Pregnancies, therefore, are always the result of unions of domestic sows with feral males. During one twelve-month period only fourteen litters resulted out of a potential 99 or more pregnancies. Only 32 of the offspring of the above mentioned fourteen pregnancies were alive six months after birth. This number is barely sufficient to replace the number of adult animals which would have died or been killed during most years without pig festivals. In ordinary times, when there is no pig festival in progress, the rituals are almost always associated with misfortunes or emergencies, notably warfare, illness, injury, or death. Rules state not only the contexts in which pigs are to be ritually slaughtered, but also who may partake of the flesh of the sacrificial animals. In cases of illness or injury, it is only the victim and certain near relatives, particularly his co-resident agnates and spouses, who do so.

While primary dysmenorrhea occurs before the age of 20 herbs pool cheap geriforte 100mg line, secondary dysmenorrhea may occur at any age herbs used for medicine discount geriforte 100 mg line. In ovarian dysmenorrhea herbs philipson purchase geriforte 100 mg without prescription, the pain is referred to the area innervated by T10 to L1 segments. Right ovarian vein syndrome is due to engorgement of right ovarian vein premenstrually so as to compress the right ureter with resultant pyelonephritis and pain. Hysterectomy with bilateral salpingo-oophorectomy in patients approaching menopause may be an option. Causes: Menorrhagia is a symptom of some underlying pathology-organic or functional. Emotional upset Functional Due to disturbed hypothalamo-pituitary-ovarianendometrial axis. Definition Polymenorrhea is defined as cyclic bleeding where the cycle is reduced to an arbitrary limit of less than 21 days and remains constant at that frequency. If the frequent cycle is associated with excessive and or prolonged bleeding, it is called epimenorrhagia. Hyperstimulation of the ovary by the pituitary hormones may be the responsible factor. While metrorrhagia strictly concerns uterine bleeding but in clinical practice, the bleeding from any part of the genital tract is included under the heading. Causes the causes may be local (uterine synechiae or endometrial tuberculosis), endocrinal (use of oral contraceptives, thyroid dysfunction, and premenopausal period), or systemic (malnutrition). Incidence the prevalence varies widely but an incidence of 10 percent amongst new patients attending the outpatient seems logical. The bleeding may be abnormal in frequency, amount, or duration or combination of any three. Pathophysiology the physiological mechanism of hemostasis in normal menstruation are: (1) Platelet adhesion formation. The endometrial abnormalities may be primary or secondary to incoordination in the hypothalamopituitary-ovarian axis. It is thus more prevalent in extremes of reproductive period-adolescence and premenopause or following childbirth and abortion. Emotional influences, worries, anxieties, or sexual problems sometimes are enough to disturb the normal hormonal balance. The follicular development is speeded up with resulting shortening of the follicular phase. Rarely, the luteal phase may be shortened due to premature lysis of the corpus luteum. Endometrial study prior to or within few hours of menstruation reveals secretory changes. There is undue prolongation of the proliferative phase with normal secretory phase. Irregular shedding of the endometrium the abnormality is usually met in extremes of reproductive period. In irregular shedding, desquamation is continued for a variable period with simultaneous failure of regeneration of the endometrium. Endometrial sampling performed after 5th or 6th day of the onset of menstruation reveals a mixture of secretory and proliferative endometrium. Irregular ripening of the endometrium There is poor formation and inadequate function of the corpus luteum. Secretion of both estrogen and progesterone is inadequate to support the endometrial growth. The endocrine profile in the luteal phase shows persistent low level of urinary pregnanediol level of less than 3 mg or plasma progesterone level less than 5 ng/mL. Endometrial study prior to or soon after spotting reveals patchy area of secretory changes amidst proliferative endometrium. In the absence of growth limiting progesterone due to anovulation, the endometrial growth is under the influence of estrogen throughout the cycle. There is inadequate structural stromal support and the endometrium remains fragile. The net effect is gradual rise in the level of estrogen with concomittant phase of amenorrhea for about 68 weeks. As there is no ovulation, the endometrium is under the influence of estrogen without being opposed by growth limiting progesterone for a prolonged period. After a variable period, however, the estrogen level falls resulting in endometrial shedding with heavy bleeding. Bleeding also occurs when the endometrial growth have outgrown their blood supply. Due to increased endometrial thickness, tissue breakdown continues for a long time. Bleeding is prolonged until the endometrium and blood vessels regenerate to control it. Changes in the uterus: There is variable degree of myohyperplasia with symmetrical enlargement of the uterus to a size of about 810 weeks due to simultaneous hypertrophy of muscles. On naked eye examination, the endometrium looks thick, congested and often polypoidal (multiple polyposis). Microscopically (a) There is marked hyperplasia of all the endometrial components. There is however, intense cystic glandular hypertrophy rather than hyperplasia with marked disparity in sizes. In about 30 percent, the endometrium is hyperplastic and in the remaining, there are evidences of irregular shedding, irregular ripening, or atrophic pattern. Investigations the investigation aims at: To confirm the menstrual abnormality as stated by the patient. The glands Firstly, it is to be confirmed that the bleeding is are empty and lined by columnar epithelium.

If ambiguity is Changes in the ovary: Cystic changes may be found from the estimated hemoglobin percentage, it is observed involving one or both the ovaries. The better to assess the blood loss by admitting the patient cyst may be single or multiple and the fluid contains during period. There is no menorrhagia, only about 50 percent have got excess blood loss (> 80 mL). Nature of menstrual abnormality is then to be Confusion in diagnosis: Phase of amenorrhea followed by continued bleeding per vaginum with enquired-cyclic or acyclic, its relation to puberty, bulky uterus is too often confused with disturbed pregnancy events and last normal cycle.
