The stressful events or the continuing unpleasant circumstances are the primary and overriding causal factor and the disorder would not have occurred without their impact impotence may be caused from quizlet order genuine caverta on line. The disorders in this section can thus be regarded as maladaptive responses to icd 9 code erectile dysfunction neurogenic discount 50mg caverta visa severe or continued stress erectile dysfunction epilepsy medication buy caverta pills in toronto, in that they interfere with successful coping mechanisms and therefore lead to problems of social functioning. Acute stress reaction A transient disorder that develops in an individual without any other apparent mental disorder in response to exceptional physical and mental stress and that usually subsides within hours or days. Individual vulnerability and coping capacity play a role in the occurrence and severity of acute stress reactions. The symptoms show a typically mixed and changing picture and include an initial state of "daze" with some constriction of the field of consciousness and narrowing of attention, inability to comprehend stimuli, and disorientation. This state may be followed either by further withdrawal from the surrounding situation (to the extent of a dissociative stupor-F44. Autonomic signs of panic anxiety (tachycardia, sweating, flushing) are commonly present. The symptoms usually appear within minutes of the impact of the stressful stimulus or event, and disappear within two to three days (often within hours). Typical features include episodes of repeated reliving of the trauma in intrusive memories ("flashbacks"), dreams or nightmares, occurring against the persisting background of a sense of "numbness" and emotional blunting, detachment from other people, unresponsiveness to surroundings, anhedonia, and avoidance of activities and situations reminiscent of the trauma. There is usually a state of autonomic hyperarousal with hypervigilance, an enhanced startle reaction, and insomnia. Anxiety and depression are commonly associated with the above symptoms and signs, and suicidal ideation is not infrequent. The onset follows the trauma with a latency period that may range from a few weeks to months. In a small proportion of cases the condition may follow a chronic course over many years, with eventual transition to an enduring personality change (F62. Traumatic neurosis Adjustment disorders States of subjective distress and emotional disturbance, usually interfering with social functioning and performance, arising in the period of adaptation to a significant life change or a stressful life event. Individual predisposition or vulnerability plays an important role in the risk of occurrence and the shaping of the manifestations of adjustment disorders, but it is nevertheless assumed that the condition would not have arisen without the stressor. The manifestations vary and include depressed mood, anxiety or worry (or mixture of these), a feeling of inability to cope, plan ahead, or continue in the present situation, as well as some degree of disability in the performance of daily routine. The predominant feature may be a brief or prolonged depressive reaction, or a disturbance of other emotions and conduct. All types of dissociative disorders tend to remit after a few weeks or months, particularly if their onset is associated with a traumatic life event. More chronic disorders, particularly paralyses and anaesthesias, may develop if the onset is associated with insoluble problems or interpersonal difficulties. These disorders have previously been classified as various types of "conversion hysteria". They are presumed to be psychogenic in origin, being associated closely in time with traumatic events, insoluble and intolerable problems, or disturbed relationships. Medical examination and investigation do not reveal the presence of any known physical or neurological disorder. In addition, there is evidence that the loss of function is an expression of emotional conflicts or needs. The symptoms may develop in close relationship to psychological stress, and often appear suddenly. Only disorders of physical functions normally under voluntary control and loss of sensations are included here. Disorders involving pain and other complex physical sensations mediated by the autonomic nervous system are classified under somatization disorder (F45. The possibility of the later appearance of serious physical or psychiatric disorders should always be kept in mind. The amnesia is usually centred on traumatic events, such as accidents or unexpected bereavements, and is usually partial and selective. The diagnosis should not be made in the presence of organic brain disorders, intoxication, or excessive fatigue. Excludes: alcohol- or other psychoactive substance-induced amnesic disorder (F10-F19 with common fourth character. In addition, there is positive evidence of psychogenic causation in the form of recent stressful events or problems. Include here only trance states that are involuntary or unwanted, occurring outside religious or culturally accepted situations. There may be close resemblance to almost any variety of ataxia, apraxia, akinesia, aphonia, dysarthria, dyskinesia, seizures, or paralysis. There may be differential loss between the sensory modalities which cannot be due to a neurological lesion. Psychogenic deafness Mixed dissociative [conversion] disorders Combination of disorders specified in F44. If any physical disorders are present, they do not explain the nature and extent of the symptoms or the distress and preoccupation of the patient. Most patients have a long and complicated history of contact with both primary and specialist medical care services, during which many negative investigations or fruitless exploratory operations may have been carried out. The course of the disorder is chronic and fluctuating, and is often associated with disruption of social, interpersonal, and family behaviour. Undifferentiated psychosomatic disorder Hypochondriacal disorder the essential feature is a persistent preoccupation with the possibility of having one or more serious and progressive physical disorders. Patients manifest persistent somatic complaints or a persistent preoccupation with their physical appearance. Normal or commonplace sensations and appearances are often interpreted by patients as abnormal and distressing, and attention is usually focused upon only one or two organs or systems of the body. Marked depression and anxiety are often present, and may justify additional diagnoses. Body dysmorphic disorder Dysmorphophobia (nondelusional) Hypochondriacal neurosis Hypochondriasis Nosophobia F45. The symptoms are usually of two types, neither of which indicates a physical disorder of the organ or system concerned. First, there are complaints based upon objective signs of autonomic arousal, such as palpitations, sweating, flushing, tremor, and expression of fear and distress about the possibility of a physical disorder. Second, there are subjective complaints of a nonspecific or changing nature such as fleeting aches and pains, sensations of burning, heaviness, tightness, and feelings of being bloated or distended, which are referred by the patient to a specific organ or system. The result is usually a marked increase in support and attention, either personal or medical. Pain presumed to be of psychogenic origin occurring during the course of depressive disorders or schizophrenia should not be included here. In one type, the main feature is a complaint of increased fatigue after mental effort, often associated with some decrease in occupational performance or coping efficiency in daily tasks.
Cardiovascular System Differentiation between Congenital and Acquired Complete Heart Block Congenital complete heart block 1 erectile dysfunction protocol book download order caverta line. Heart rate can increase with exertion or stress (as junctional escape rhythm is under autonomic control) 8 erectile dysfunction specialist doctor purchase caverta without prescription. Idiopathic Dilatation of the Pulmonary Artery Idiopathic dilatation of the pulmonary artery is a relatively uncommon congenital defect characterised by a congenital dilatation of the main pulmonary trunk erectile dysfunction doctor austin purchase 100mg caverta. This may be associated with pulmonic regurgitation or progressive dilatation and aneurysm formation. Coronary Arteriovenous Fistula It is a communication between a coronary artery and a cardiac chamber. The fistula most commonly arises from the right coronary artery or its branches and usually drains into the right ventricle, right atrium or coronary sinus. It results in a left-to-right shunt that is usually small, so that coronary blood flow is rarely compromised. Infective endocarditis Pulmonary hypertension (if shunt is large) Rupture or thrombosis of fistula Myocardial ischaemia. The presence of a right ventricular impulse is incompatible with a diagnosis of idiopathic dilatation of the pulmonary artery, since this condition causes neither pressure nor volume overload of the right ventricle. Erythema Marginatum (< 5% and evanescent) Macular lesions with an erythematous rim and central clearing in a bathing suit distribution are seen in < 5% of patients and occur early in rheumatic fever. Anomalous Origin of a Coronary Artery from the Pulmonary Artery this may involve either the main right or left coronary arteries or their branches. Pericarditis is Essential Criteria Evidence for recent streptococcal infection as evidenced by: Cardiovascular System 1. Two major (or) one major and two minor criteria, in the presence of essential criteria, is required to diagnose Acute Rheumatic Fever. A Positive Rheumatic Fever history is usually elicited in only 50% of patient with Rheumatic Heart Disease. So, the mitral valve is more susceptible to develop pathological changes than the aortic valve. Prophylaxis must continue, up to the age of 25 years or 5 years after the last attack, whichever is longer. Rheumatic fever with carditis without valvular lesion-10 years or until the age of 25 years (whichever is longer). Pulmonary apoplexy due to rupture of thin-walled, dilated broncho-pulmonary veins usually as a consequence of a sudden rise in left atrial pressure. According to the Gradient Across Stenotic Mitral Valve Normal valve gradient is 0 mm Hg Cardiovascular System Chest Pain Anginal pain may be due to coincidental coronary atherosclerosis or secondary to coronary embolisation. Angina like pain occurs in severe pulmonary hypertension due to hypoxia, hypotension and reduced cardiac output. Pulmonary Haemosiderosis and Ossification It may occur in long-standing pulmonary hypertension. Echocardiogram Thickened immobile cusps; reduced rate of diastolic filling; reduced valve area. This procedure is similar to that of closed mitral valvotomy except that the hospital stay is minimised and there is no scar. Among the mechanical prosthesis, tilting-disc valve is preferred to caged ball valve because: a. It occupies less space and hence useful in patients with a small left ventricle b. Life long anticoagulation is indicated in patients receiving mechanical prosthesis. The advantage of bioprosthetic valve is the low incidence of thromboembolic phenomenon. Bioprosthetic valves are not usually used in young patients < 65 years because of its rapid deterioration. However, they are useful in pregnancy, when there is contraindication to the use of anticoagulants and also in older patients over 65 years of age. There is excessive or redundant mitral leaflet tissue, with myxomatous degeneration and increased concentrations of acid mucopolysaccharide. A high pitched late systolic crescendo-decrescendo murmur (whooping or honking) heard best at the apex. Most common cause of combined mitral stenosis and mitral regurgitation is rheumatic heart disease. Echocardiogram Useful in identifying the abnormal position and prolapse of the mitral valve leaflets. Mitral valve prolapse is diagnosed when systolic displacement of mitral leaflets > 2 mm into the left atrium with coaptation superior to the plane of mitral annulus. Patients with rheumatic aortic stenosis almost always have concomitant mitral valve involvement. Symptoms Angina, dyspnoea, syncope, dizziness, sudden death (may be as a result of intolerance to complete heart block or atrial tachyarrhythmia). According to S2 Mild stenosis Moderate stenosis Severe stenosis A2 followed by P2 A2 is delayed giving rise to single S2 Reverse splitting of S2 (P2-A2).

Keywords: Urban Governance erectile dysfunction on molly buy 100 mg caverta visa, Human Development erectile dysfunction pills cost 50 mg caverta for sale, Challenges the International Academic Forum These changes/shifts have been erectile dysfunction doctor denver purchase discount caverta line, unfortunately, accompanied by the ills of power centric uni-polar world, widening gaps between the rich and the poor, neocolonialism, violence, ethnic-conflicts, terrorism, etc. Is it enough just to codify rules, regulations, policies, and procedures by the government or more participatory norms for better governance needs to be evolved? The major onslaught of these above mentioned challenges is increasingly visible in the cities, and more so in the cities in developing countries. Globalization, environment, gender, decentralization, poverty, and sustainable development (to mention few) are issues that call for newer and better urban agenda. Government is described as "the complex of political institutions, laws, and customs through which the function of governing is carried out in a specific political unit. Many definitions of governance include three principal groups of actors: government, the private sector and the civil society. It recognizes that decisions are made based on complex relationships between many actors with different priorities. It is a reconciliation of these competing priorities that is at the heart of the concept of governance. The already intricate task of governance becomes all the more obscure in the context of the present urban areas comprising mainly of cities with open boundaries, complete fluidity, and excessive population influx. Also, while the phenomenon of urbanization is widely accepted as being as inevitable by-product of development, there are many undesirable fall-outs also. For example, in India, rapid urbanization has resulted in housing, electricity, water, and sanitation problems; poverty; slums; regional imbalance; need for better town planning; crime; waste management; emerging markets and their management; 340 the Asian Conference on the Social Sciences 2016 Official Conference Proceedings street vendors and their management; prostitution; traffic management; public security issues; etc. Thus the importance of urban governance, generally in the developing countries, has increased enormously in recent years. It is a continuing process through which conflicting or diverse interests may be accommodated and cooperative action can be taken. It includes formal institutions as well as informal arrangements and the social capital of citizens". Basic Features of Urbanization in India the urban centers in India primarily depict cities inhabited, on the one hand, by a population who benefit directly from the economic growth and the resultant infrastructural development in that city and on the other hand by the people having no access even to food, water, health, housing, etc. Thus the challenge before the urban governance is not only of providing facilities for this mix of population but also of their social inclusion. Urbanization is mainly a product of demographic explosion and poverty induced rural-urban migration. Rapid urbanization leads to massive growth of slum followed by misery, poverty, unemployment, exploitation, inequalities, degradation, in the quality of urban life. Resultant pressures and problems Slums, jhuggis, footpath dwellers, squatters; pressure on civic infrastructure like water supply, sewerage and drainage, solid waste management, etc; crime and illegal activities like electricity theft etc. Institutional mechanism, financial requirements and development needs have been the favorite agenda of almost all formal and informal structures and mechanisms involved in urban governance. But the human development challenge is the most complex agenda of urban governance. Or should we go beyond all this and see development as enhancing the lives and freedom of people involved. Sen, concerns the relation between incomes and achievements, commodities and capabilities, between our economic wealth and our ability to live as long and as well as we would like. Human development should be viewed not as an economic activity, linked with material prosperity and wealth/ income-growth concepts in the physical sense, but defined primarily from the point of view of moral and individual upliftment, self-realization through spiritual enrichment and a holistic approach towards the purpose of human existence. Human development is first and foremost about allowing people to lead the kind of life they choose and providing them with the tools and opportunities to make those choices. Our constitution provides numerous rights in accordance with the need of human development.

His behavior, values, norms and beliefs has the potential to make or unmake, to do or undo and to create or destroy everything. Since it is the man where culture, ethics and character inheres; he should be treated as a means as well as an end. Critical focus should be on inculcation of moral values and generation of an environment where a culture of character can evolve. Work culture, commitment towards values (family, society, and nation), ethics, and character are the worst casualties. Values, ethos, norms, behavior, character, and attitudinal aspects inherent to "citizen-ness" needs to developed. Organizations and institutions are structurally and financially equipped to initiate formal capacity building programmes comprising of skill development, work place administrative training, understanding rules and regulations, public dealing, etc. But such training modules hardly focus on the behavioral and attitudinal aspects of the employees. Apart from those who are staying in urban areas, such urban centers are constantly visited by people from rural areas also for multiple routine governmental tasks. Untrained employees perform poorly at such places and present a bad face of the city governments to the people. Therefore what is required is that the city governments should introduce a systematic program of training to develop the skills of employees and to enable them to deal with the public gently and efficiently. Overcoming crises of Confidence: the interface between the citizens and the government exhibits traits of non-responsiveness both ways. Institutional mechanism of the urban government is non-responsive to the citizens and vice versa. The residents, on the other hand, do not identify with it as it is perceived to be unresponsive and apathetic to civic problems. The citizenry and business enterprises have lost faith in the system because of its corrupt practices and hostile attitudes. People are unwilling to collaborate with civic authorities and are apprehensive and reluctant to participate in the new approaches initiated by government agencies.

Cancer is second only to erectile dysfunction medicine from dabur discount caverta 100 mg fast delivery coronary artery disease as the most common cause of death erectile dysfunction funny images purchase caverta 100mg on line. Over activation of proto-oncogenes by point mutation erectile dysfunction heart discount caverta 100 mg without a prescription, amplification or dysregulation results in the formation of oncogenes. Genes that normally restrains cell growth are called tumour suppressors and unregulated cell growth occurs if their function is lost. Cancer can arise as a result of either over activation of oncogenes or loss of function of tumour suppressor genes. Cell Biology of Cancer Cancer is most common in tissues with rapid turnover especially those exposed to environmental carcinogens and whose proliferation is regulated by hormones. Tissues with no turnover: They persist throughout life without dividing or being replaced. Benign neoplasm: In benign lesions the uncontrolled growth of abnormal cells remain within the tissue of origin. The treatment of solid tumours is usually surgery, radiation, chemotherapy or combination of these modalities. Grade the percentage of cells in a tumour that retain the character of the parent cell of origin is taken into account to grade the tumour. It is defined as low, moderate, or high depending on the amount of tissues that loses its normal appearance. It is useful for assessing the prognosis of many tumours, but not useful for treatment plans.

High animal fat increases cholesterol level which increases the risk for colon cancer. Alcohol abuse, excess coffee consumption and cholelithiasis are not risk factors for pancreatic cancer. Head and Neck Cancer Includes tumours of oral cavity, nasopharynx, oropharynx, hypopharynx and larynx. Clinical Features of Cancer General Features Cachexia General ill health due to altered metabolism, anorexia, weight loss, is seen as a common manifestation of gastrointestinal cancers, cancers of lung, ovaries, testes and uncommonly in breast cancers, intracranial tumours, leukaemia and lymphoma. Cancer Anorexia and Cachexia this syndrome consists of anorexia, distortion of taste perception, and loss of muscle mass. Gastric Cancer Small superficial and surgically removable lesion is usually asymptomatic. Hypertrophic Osteoarthropathy It is an advanced stage of clubbing associated with polyarthritis and periostitis involving the long bones, most often seen in non-small cell lung cancer and metastatic mediastinal nodes due to other cancers. Rare manifestations include dermatomyositis, acanthosis nigricans, glomerulonephritis.

Land seldom remains in a state of equilibrium and often exhibits multiple ecological and social states. Underlying socio-economic processes can move systems slowly towards thresholds, and once reached, the bio-physical integrity of the system can rapidly be interrupted. This process is also known as non-linear regime shifts and can be extremely difficult and costly to reverse. To understand land degradation and prioritize action, there is a need to identify and manage for the small set of "slow changing" variables. These thresholds need to be evaluated and the cost of recovery quantified in order to seek ways of managing the thresholds to increase resilience (Reynolds et al. The identification of a unifying concept or explanation for land degradation processes is still a challenge. Such complexity can be tackled referring to the concept of "syndromes" (Ceccarelli et al. This can serve as information baselines for sustainable land management strategies and interventions. Still, challenges exist to develop an effective scenario pathway to develop the future land degradation trajectories. There is a need, through proactive science and policy dialogue to: (i) embrace a long-term scenario strategy that has the potential to significantly improve the relevance of future assessments on biodiversity and ecosystem services; and (ii) adopt a participatory, multiscale scenario approach that captures the diversity of local social-ecological dynamics and builds understanding of interactions between global and local processes intertwined in generating ecosystem services and human well-being (Kok et al. Therefore, a comprehensive assessment of the biophysical, socio-economic and governance/ institutional variables is essential to make informed decisions on restoration. This document outlines procedural guidance for the whole life cycle of the management of contaminated sites. The guidance is given in the form of guidelines and manuals that are used (as decision support tools) by local authorities and practitioners taking responsibility for the investigation, remediation and aftercare of contaminated sites. In addition to the written guidelines, software-based tools are also developed for remediation of contaminated sites in Europe (Onwubuya et al. There is a large variety of ecosystem-based management tools that can be applied for selecting a solution for land degradation (Table 8. The tools can be found in the "Ecosystem-Based Management Tools Database, 2012". While prevention lies in proactive policy decisions on conservation and the sustainable use of resources, restoration is a forwardlooking process that seeks to initiate or accelerate the recovery of an ecosystem from a degraded state. The decision on a restoration option needs to be goal oriented, specific to a certain ecosystem, at various scales taking into account the recovery potential of the system as well as the needs of the society (see Chapter 1 and 6). Hence, defining clear restoration goals requires not only the identification of plausible options that are available for the particular ecosystem, but also considerations of the diverse interests of stakeholders. Besides, restoration and degradation mitigation responses are constrained by variables such as available resources. It also allows the selection of technological options by taking into account of stakeholder interests and views. Costs can be considered not only as monetary context, but also anything that can reduce human well-being - while benefits are anything that can enhance human and environmental well-being. It is a relatively simple balance of the costs of a measure against its effectiveness and whether it meets given restoration objectives. The tool can be used to synthesize data and information on identified problems and organize a set of decision criteria for each category of problems, so as to enable decision makers to choose the appropriate solutions. The technique is often used to analyze for example the "cradle to grave" of products. The technique restores degraded sites through uptake of selected contaminants by specifically-selected plants (a process called phytoextraction) and through immobilization of contaminants through re-vegetation of sites with target species of plants and through the addition of other chemical inputs to immobilize the pollutants (mainly metals and metalloids), which is a process of phytostabilization. Among the web-based tools, Co$ting Nature is a model that aims to facilitate decisions on conservation priorities and to assess impacts of development activities such as agricultural production, mining, industrial developments on ecosystem services, as a result of human pressure on biodiversity and ecosystem services. Some of the above-mentioned tools have been applied in a variety of ecosystems (Box 8. Spatial modelling and decision support tools can provide decision makers with information on optimal options in restoring degraded ecosystems (Goldstein et al. The findings showed that while the biophysical services were distributed with high spatial variability, the social values had high spatial overlap. About 6% of the watershed area showed both high biophysical and social services, while about 24. The results indicate trade-offs and potential synergies between development, social values and biophysical services. The results can be used for finding solutions to social-ecological planning complexities that serve multiple stakeholders. The results of the comparison can also inform decision makers and prompt further discussion about conflicting priorities. The study was aimed at making a comparative spatial analysis of biophysical service areas with social value areas. Land-use suitability maps, which ultimately dictate future land-use change, were calculated based on both land-use allocation maps and direct drivers of environmental variables. The systematic conservation planning zonation then generated spatial-prioritization scenarios based on different inputs. It is a quantitative analytical step that is often utilized within a broader operational framework for the implementation of conservation, such as systematic conservation planning (Kukkala & Moilanen, 2013). Most common analyses are based on data about the distributions of species and habitat types, but additional information about costs, threats (including land degradation), connectivity or ecosystem services is sometimes used depending on analysis needs and data availability. The original form of the conservation area selection problem is a target-based formulation: which set of sites satisfies targets given for biodiversity features (often species) with minimum cost (see Moilanen et al. This type of problem is frequently solved with the Marxan or Marxan with Zones software (Watts et al. Spatial priority ranking is often done using the Zonation approach and software (see application examples in Box 8. Linking land degradation to spatial conservation prioritization can help answer the following types of questions: (i) How much biodiversity has been lost due to land degradation compared to the reference state? The methodology is meant to be quick and non-technical, allowing broad stakeholder engagement in the process.

It is now recognized that various hypotheses can be advanced to erectile dysfunction cure video cheap 50 mg caverta visa explain this major event in vegetation history: the original climatic interpretation; progressive soil deterioration; the spread of disease; or the role of people erectile dysfunction treatment new jersey 50 mg caverta otc. The climatic interpretation of the elm decline as being caused by cold erectile dysfunction doctors near me cheap caverta 100mg mastercard, wet conditions has been criticized on various grounds (Rackham, 1980: 265): A deterioration of climate is inadequate to explain so sudden, universal and specific a change. Had the climate become less favourable for elm, this would not have caused a general decline in elm and elm alone; it would have wiped out elm in areas where the climate had been marginal for it, but would not have affected elm at the middle of its climatic range unless the change was so great as to affect other species also. A climatic change universal in Europe ought to have some effect on North American elms. In Denmark it was found that the first appearance of the pollen of a weed, Ribwort plaintain (Plantago lanceolata), always coincided with the fall in elm pollen levels, confirming the association with human settlements. Experiments have also shown that Neolithic peoples, equipped with polished stone axes, could cut down mature trees and clear by burning a fair-sized patch of established forest within about a week. Remarkably, more than 100 trees were felled with one axe head, which had not been sharpened for about 4000 years (Cole, 1970: 38). Rackham, however, doubts whether humans alone could have achieved the sheer extent of change in such a short period (see also Peglar and Birks, 1993) and postulates that epidemics of elm disease may have played a role, aided by the fact that the cause of the disease, a fungus called Ceratocystis, is particularly attracted to pollarded elms (Rackham, 1980: 266). In reality the elm decline may have resulted from a complex cocktail of causes relating to climate change, soil deterioration, disease and human activity. The elm was not the only tree to show a decline in lowland Britain during the mid- Holocene. The lime (Tilia) disappeared as a result of clearance activity in the Late Neolithic to the Late Bronze Age (Grant et al. Lowland heaths Heathland is characteristic of temperate, oceanic conditions on acidic substrates and is composed of low shrubs, which form a closed canopy at heights which are usually less than 2 m. There are also welldocumented examples of heath communities which appear naturally in the course of plant succession as, for example, where Calluna vulgaris (heather) colonizes Ammophila arenaria (marram grass) and Carex arenaria (sand sedge) on coastal dunes. However, at low and medium altitudes on the western fringes of Europe and North Africa between Morocco, Iberia and Scandinavia (Figure 2. Some areas were once thought to have developed where there were appropriate edaphic conditions. This evidence alone, however, did not settle the question whether the change from forest to heath might have been caused by Holocene climatic change. However, the presence of human artefacts and buried charcoal, and the fact that the replacement of forest by heath has occurred at many different points in time between the Neolithic and the late nineteenth century, suggest that human actions established, and then maintained, most of the heathland areas. In particular, fire is an important management tool for heather in locations such as upland Britain, since the value of Calluna as a source of food for grazing animals increases if it is periodically burned. The area covered by heathland in Western Europe reached a peak around 1860, but since then there has been a very rapid decline. Reductions in Britain averaged 40% between 1950 and 1984, and this was a continuation of a more long-term trend which saw a decline of 3. The reasons for this fall are many and include unsatisfactory burning practices, peat removal, drainage fertilization, replacement by improved grassland, conversion to forest, and sand and gravel abstraction. The nature of lowland heaths is also currently being modified by the effects of increasing levels of nitrate additions from the atmosphere, which effects the growth of lichens and Calluna (Southon et al. Thus far we have considered the human impact on general assemblages of vegetation over broad zones. However, in turning to questions such as the range of individual plant species, the human role is no less significant. Introduction, invasion and explosion People are important agents in the spread of plants and other organisms. Some plants are introduced deliberately by humans to new areas; these include crops, ornamental and miscellaneous landscape modifiers (trees for reafforestation, cover plants for erosion control, etc. Indeed, some plants, such as bananas and breadfruit, have become completely dependent on people for reproduction and dispersal, and in some cases they have lost the capacity for producing viable seeds and depend on human-controlled vegetation propagation. Most cultigens are not able to survive without human attention, partly because of this low capacity for self-propagation, but also because they cannot usually compete with the better-adapted native vegetation. Examples of such plants include several umbelliferous annual garden crops (fennel, parsnip and celery) which, though native to Mediterranean Europe, have colonized wastelands in California. The Irish potato, which is native to South America, grows unaided in the mountains of Lesotho. The peach (in New Zealand), the guava (in the Philippines), coffee (in Haiti) and the coconut palm (on Indian Ocean island strands) are perennials that have established themselves as wild-growing populations, though the last-named is probably within the hearth region of its probable domestication. In Paraguay, orange trees (originating in Southeast Asia and the East Indies) have demonstrated their ability to survive in direct competition with natural vegetation. Plants that have been introduced deliberately because they have recognized virtues (Jarvis, 1979) can be usefully divided into an economic group. In the British Isles, Jarvis believes that the great bulk of deliberate introductions before the sixteenth century had some sort of economic merit, but that only a handful of the species introduced thereafter were brought in because of their utility. Instead, plants were introduced increasingly out of curiosity or for decorative value. A major role in such deliberate introductions was played by European botanic gardens (Figure 2. Many plants, however, have been dispersed accidentally as a result of human activity: some by adhesion to moving objects, such as individuals themselves or their vehicles; some among crop seed; some among other plants (like fodder or packing materials); some among minerals (such as ballast or road metal); and some by the carriage of seeds for purposes other than planting (as with drug plants). In the Pampa of Argentina, Schmieder (1927b) estimates that the invasion of the country by European plants has taken place on such a large scale that at Figure 2. The accidental dispersal of such plants and organisms can have serious ecological consequences (see Williamson, 1996, and Henderson et al. In Britain, for instance, many elm trees died in the 1970s because of the accidental introduction of the Dutch elm disease fungus which arrived on imported timber at certain ports, notably Avonmouth and the Thames Estuary ports (Sarre, 1978). There are also other examples of the dramatic impact of some introduced plant pathogens (von Broembsen, 1989). The American chestnut Castanea dentata was, following the introduction of the chestnut blight fungus Cryphonectria parasitica in ornamental nursery material from Asia late in the 1890s, almost eliminated throughout its natural range in less than 50 years. Two North American hemlock species, Tsuga Canadensis and Tsuga caroliniana, have been threatened by another accidental Asian invader, a small sap-sucking insect, Adelges tsugae (Nuckolls et al. In western Australia the great jarrah forests have been invaded and decimated by a root fungus, Phytophthora cinnamomi. This was probably introduced on diseased nursery material from eastern Australia, and the spread of the disease within the forests was facilitated by road building, logging and mining activities that involved movement of soil or gravel containing the fungus. From 1935 to the mid-1950s it was recommended as a good means of reducing soil erosion.

He used a battery and put the positive pole over the lower back and the negative over the crural nerve of the leg erectile dysfunction purchase caverta 50 mg. After a half-hour of direct current therapy erectile dysfunction protocol food lists discount 50mg caverta with mastercard, he was able to erectile dysfunction meds buy 50mg caverta with amex rise and dress himself. Samuel Monell seated patients on an insulating platform and connected his static machine to the negative pole with the positive pole grounded. He once treated a 27-year-old woman with arthritis in her ankle, knee and shoulder. She stepped onto the static platform and he applied a hot negative spray to the spine, the neck and upper chest. After two minutes, she was able to walk normally with a sense of warmth and comfort. The next time the electrotherapist treated him with a powerful beam of light, and this relieved all of his pain. After two treatments of static wave current, he was able to straighten up the limb and move about without pain. After six treatments, his knee was so improved that he could flex his legs and live normally. The static brush current was applied to the back of the hand and the problem healed up. Stephane Leduc was able to treat some painful movement conditions with electrical ions. A woman fractured the neck of the femur two years earlier and she was unable to raise her foot from the ground. He treated the area with six applications of sodium salicyclate ions at a current of 60-80 milliamps for half an hour. After using an electrical solution of sodium chloride for 30 minutes he recovered normal finger movement. He moved to Texas and began to work at the first electric power station in Galveston. He found that it was a general belief among the workmen that the pulsing fields from the electrical dynamos cured their arthritis. One doctor used a combination of the violet ray and ionization to treat arthritis. A policeman had rheumatoid arthritis in one knee, which steadily got worse, so he had to walk with a crutch. Albert Laquerriere and Georges Apostoli used high-frequency treatments in a number of cases of rheumatism. A woman was unable to stand or move her knee joints, which were bent at nearly right angles. Her illness began 28 years before, when she suffered from pain in the toes of the right foot. With three weeks of treatment, there was little pain and the joints were more pliable. She can move her knee-joints with a fair amount of comfort, and she can grasp with her hands much better than on admission. Gamlen noted that all of his patients had been treated with many drugs without effect. Gamlen treated a 41-year-old hat maker with rheumatoid arthritis and a lack of energy. She took the bath cure at Harrogate and Matlock, but her doctors finally said that she should prepare to be a "hopeless cripple. She was given 10- to 15-minute violet ray treatments three times a week with sparking of the limbs. A woman suffered from pain and tenderness with swellings in the joints of the hands and wrist. In five weeks the pain and tenderness had entirely disappeared and the swelling was hardly noticeable. A young girl had acute arthritis of the left ankle joint with a large swelling circling her ankle and intense pain. She took 15 minute treatments on the first two days, which began to 292 293 relieve her. It took months for the hands to return to normal but the violet ray did miracles for him. In 1983, Chinese doctors published a study of the treatment of 42 people with spasmodic torticollis. After about 10 minutes of treatment the patient was instructed to perform voluntary head movements. After one treatment of the Renulife Violet Ray, I was able to get up the next morning. I take great pleasure in recommending violet ray treatments to anyone who is afflicted with rheumatism or lumbago. Many traveling men who stop at my hotel, knowing my condition for two years and more, have asked me what brought me out and I take them upstairs to our rooms and show them the Violetta. I have not been entirely free from this pain until yesterday after using the Violetta. I gave her 20 treatments with the Violetta and now she gets up and walks about as well as ever.
