  • Most crop insurance policies are either production-based or revenue- based. For production-based policies, a farmer can receive a payment if there is a production loss relative to the farmer’s historical production per acre. Revenue-based policies protect against crop revenue loss resulting from declines in production, price, or both.

  • I highly recommend this chapter to all radiologists involved in the management of abdominal trauma patients and to trauma surgeons and intensive care physicians. Anesthesia is a medical treatment which leads human body to abnormal condition. This means that anesthetic management is always accompanied by risks of accidental events, and "vigilance" is considered as the most important duty of anesthesiologists.

  • The second section of the book collects studies on pathophysiology of ischemic damage. This is an area where our knowledge has greatly advanced in the past decade, mainly due to the study of novel pathways of damage and of novel techniques to investigate them. Better knowledge of how brain tissue becomes damaged in stroke will hopefully lay the foundation for better therapies, be them recanalization (like thrombolysis) or neuroprotection (like hypothermia).

  • Physical and health risks are very high among the aged. The precise implications of population aging for future levels of health and health care utilisation depend on whether the increases in life expectancy experienced in general are accompanied by an increase or decrease in health problems in later life (Gruenberg, 1977; Kramer, 1980; Manton, 1982). Studies in the West show that fast decline in the mortality in the old population is creating a nightmare with high incidence of morbidity (Hainess, 1995).

  • The major symptom of the acute form of the disease is severe anaemia. However, in camels the disease due to T. evansi is usually chronic. This is typically shown in slow weight loss, intermittent high fever, general muscular weakness, especially in hind quarters, pale mucous membranes and collection of fluid, especially in the abdominal region. Packed cell volumes of blood plasma are usually 18-20% in infected animals compared to an average of 30% (range 24-42%) in healthy ones.

  • By far the most important for the present publication, in terms of the quantity mined and potential impact on the environment, are phosphate and potash. The production of phosphorous and potassium min- eral fertilizers relies essentially on the mining of mineral concentrations, in the form of ore deposits from the earth's crust. Nitrogen mineral fertilizers, on the other hand, are almost entirely based on ammonia manufactured from the abundant source of atmos- pheric nitrogen, water and energy.

  • The speculum should be carefully positioned so the entire cervix is seen. If excess mucus or other secretions obscure the cervix, they should be gently removed using a proctoswab without disturbing the epithelium. Small amounts of blood will not interfere with cytologic evaluation, but large amounts, as occurs during menses, preclude cytologic interpretation by conventional Pap smear. This is considerably less of a problem when liquid based cytology is used.

  • As with the national association segment, seasonality is another positive feature of the international association segment. These congresses tend to avoid the summer months when leisure tourism is at its peak, looking instead to the Spring and Autumn periods. There are a large group of conferences that need to be run during the academic vacation period but organisers of these events will look for destinations that have a lower hotel occupancy in the July/August period and, indeed, from mid-June to the end of September.

  • In May 2002 the Swedish National Road Administration published the report ”Bilpooler – nyckeln till flexibelt resande” ("Car-sharing - the key to combined mobility"). Much has happened since then, the development of car-sharing in Sweden having accelerated. Yet lack of knowledge regarding car-sharing is still a major factor hindering its establishment and expansion. The present report can be seen as complementing this earlier publication through presenting new documents and describing recent developments.

  • Even though actual stock returns do not verify Assumption 1, it is an acceptable first-cut approximation. This means that we abstract from lead-lag effects (Lo and MacKinlay, 1990), nonsynchronous trading (Shanken, 1987), and autoregressive conditional heteroskedasticity (Bollerslev, Engle and Woooldridge, 1988). Note that most of the current estimators for the covariance matrix of stock returns also use this assumption. Future research will be devoted to relaxing it.

  • Since the passage of resolution 1874 in 2009, the panel of experts did not learn of any official allegations about North Korea receiving or providing proscribed nuclear-related or ballistic missile-related items, technology, or know-how. Nonetheless, its review of several government, International Atomic Energy Agency (IAEA), and private assessments indicated continuing North Korean involvement in nuclear and ballistic missile related activities in certain countries, including Iran, Syria, and Myanmar.

  • Children who have congenital heart defects or who have rheumatic heart disease may develop infective endocarditis in which the endocardial tissue is infected by organisms such as Streptococcus viridans, Staphylococcus aureus, or Staphylococcus epidermidus. The child presents with general malaise, arthralgia, fever, splenomegaly and the signs of their underlying heart disease. The classical signs of splinter haemorrhages, petechiae, haemorrhagic lesions (Janeway lesions), tender Osler’s nodes, or Roth’s spots (retinal haemorrhage) are not always seen in children.

  • The findings also highlight a large proportion of individuals who could benefit from initiatives designed to change their behaviour. In almost every country surveyed, at least 3 in 10 respondents exhibited fewer that 6 of the 9 positive behaviours discussed. The analysis also shows how knowledge and behaviour are associated in every country – more knowledgeable individuals are more likely to exhibit positive financial behaviour. The data holds a great deal of potential.

  • In this paper, we propose a new approach for designing distributed systems to survive Internet catastrophes called informed replication, and demonstrate this approach with the design and evaluation of a cooperative backup system called the Phoenix Recovery Service. Informed replication uses a model of correlated failures to exploit software diversity. The key observation that makes our approach both feasible and practical is that Internet catastrophes result from shared vulnerabilities.

  • Natural rubber is produced by Hevea brasiliensis, a tree native to the Amazon region of South America. In the late eighteenth century, rubber was introduced to the Far East, which is now the main rubber-producing region of the world. Currently, the major producers of natural rubber are Thailand, Indonesia, Malaysia, India, China, Viet Nam and Sri Lanka. In 2005, the world’s production of natural rubber amounted to 8 682 million tonnes whereby 7 466 million tonnes (approximately 86 percent) originated from these seven countries.

  • The general availability of the Health Promotion Programme is ensured by the fact that it was published in the form of a book and schools can order it directly from the publisher (Prague, Portal Publishers 1998). The Ministry of Education adopted the following attitude towards the Health Promotion Programme in Schools: "The strategy of the programme of health promotion in schools is consistent with the educational concept of the Ministry of Education of the Czech Republic and its implementation is supported by the Ministry of Education (recorded under no. 24 028/98-22)".

  • The Forrest report had highlighted a number of outstanding questions about breast screening. In 1988, the UK Coordinating Committee on Cancer Research established trials on whether one view or two views of the breast should be taken and whether screening should take place more frequently than three yearly. The Forrest report identified the need for high quality mammography as paramount. Since there was little mammography in the UK at the time, this implied that a massive training effort would be needed.

  • In practice, signatures that predict toxicity or efficacy can be identified afterwards. For example, therapies targeting the Epidermal Growth Factor Receptor have been first approved before it was demonstrated that mutations in KRAS cancer gene were associated to failures of the relevant therapies in metastatic colorectal carcinoma. This example shows that well-designed retrospective analysis of data from prospective randomized controlled trials can bring forward effective treatments to biomarker defined subgroups of patients in a timely manner.
