SummaryThis report considers the role of optimisation in the asset management of a large distribution network. In particular, we look at how to determine the optimal policy for project release. Projects relating to replacement of existing assets and network re-design may be prioritised given capital rationing and/or performance improvement requirements. We focus on maintenance and replacement of a large distribution network (network structured system) and consider the application to electricity distribution networks. The electricity companies who own the UK electricity distribution networks are under pressure to provide a high quality supply to customers at minimum cost. For this particular problem a zero-one integer linear programming model is proposed for selecting an optimal project portfolio, based on the objectives and constraints of the network owner. The modelling approach described in this study would extend to the financial investment appraisal of capital projects for a broad range of manufacturing and energy related industries such as power generation, refining and water supply.

SummaryFew people would deliberately waste their valuable vacation time, even if their goal was to do nothing. And yet, many people travel through the time of their lives without a destination, without a plan, without a purpose. With an efficient planning, we significantly increase the value of our journey life.

SummaryFor years, man has been trying to find a single chemical that triggers flowering in plants. Although this single chemical has not been found, several of the Gibberellins show promising results as an active florigen – such as GA5 and GA6 and possibly GA1 and GA4. Results have shown that these GAs seem to travel intact from the leaf to the shoot apex just after a single long day photoperiod. Gibberellins also seem to accumulate in sufficient amounts to trigger flowering. Gibberellins have also been shown to cause petiole elongation. Much research still needs to be done to draw definite conclusions about the role of Gibberellins as a florigen, but much of the evidence looks promising.

- Introduction:
- Results
- King and Evans describe the advancement in proving that Gibberellins can replace the Long Day (LD) photoperiod in flowering plants
- Certain Gibberellins seem to have a greater effect on flowering than others
- The first visible change in the GAs level in plants is in the leaf soon after a long day photoperiod

SummaryBeep… beep… click… click … this just in: A pandemic breakout of unheard of proportions. Is it anthrax? Or clostridia? It could be, but authorities believe the culprit is Bacillus cereus (49133). B. cereus is a cousin strain to both Bacillus anthracis (anthrax) and Clostridia perfringens (clostridia). B. cereus is a gram-positive spore-forming and toxin-forming bacteria. Found in many starchy foods, like rice, this enterotoxin usually lasts for less than twenty-four hours. Since B. cereus is a spore producing organism, cooking food will not eliminate the threat of infection. Symptoms include abdominal pain, rectal spasm, diarrhea and nausea. Onset of these symptoms may occur 8-16 hrs after ingestion. If you, or someone you know, suffer from these symptoms, contact local health authorities immediately. Beep… beep… beep…

SummaryThe Hmong are an ethnic group indigenous to the Southeast Asian peninsula. They typically live in the mountainous regions of Vietnam, Laos and Cambodia. They are rice farmers who are well known for their embroidery and the color of their dress, which gives its name to the different Hmong clans. During the Silent War in Laos, which was fought between the Communist party, called the PL, in Laos and the US American CIA, the Hmong aided the CIA by fighting on the ground as guerilla fighters. After the Americans lost the war, the Hmong were in danger of being put into re-education camps by the new communist government in Laos. Therefore, during 1975-2004, over 300,000 Lao, or 10% of the population, mostly Hmong, resettled in America (Cummings and Burke 2005: 31). Most of the Hmong immigrants moved to Stockton, California, Seattle, Washington, Lacrosse and Madison, Wisconsin and The Twin Cities, Minnesota, where they formed Hmong communities, usually with extended families living in the same apartment building, if not the same apartment. The Hmong have had some problems finding a balance between keeping Hmong culture and tradition and adjusting to American culture and traditions.

SummaryThe cardinal manifestations of heart failure are (1) dyspnea and fatigue, which may limit exercise tolerance, and (2) fluid retention, which may lead to pulmonary and peripheral edema. Both abnormalities can impair the functional capacity and quality of life of affected individuals. In addition, by its very nature, heart failure is a progressive disorder.

SummaryFor more than 50 years, glucocorticosteroids have been important agents in treating diseases characterized by inflammation and exaggerated immune responses. The pioneering work of Hench and colleagues in rheumatoid arthritis showed the possible potency of these agents in such pathologic states.
Although substantial advances have been made in understanding the mechanisms by which glucocorticosteroids exert beneficial effects, considerable gaps in knowledge remain. Despite extensive data regarding the in vitro and in vivo activities of these drugs, it is probable that glucocorticosteroids have different beneficial activities in different diseases.

SummaryThe sound practice of medicine requires the ability to use scientific evidence that is based on data and is published in the peer-reviewed medical literature. In this literature, investigators publish their findings using descriptive statistics to summarize data and inferential statistics to test hypotheses.
Judgment is required in the choice of statistical tools and in the interpretation of statistical analyses. Physicians must have a basic understanding of statistics to benefit their patients by being informed and critical users of the medical literature.

SummaryThe traditional evaluation of the patient includes the history and physical examination and a well-planned set of diagnostic tests, often including imaging. Dramatic advances in imaging not only supplement the physical examination, but also now may begin to substitute for part of it.
Medical imaging provides an approach for dividing patients into patients who have an acute compared with a chronic medical problem and patients who have an anatomic compared with a "biochemical" illness. These determinations are crucial for prompt and effective medical and surgical therapy.

SummaryMedicine is practiced in a social, economic, and political context. It takes more than excellent medical care to improve the health of patients because many of the determinants of the health of individuals and populations lie outside traditional clinical activity.
By contrast, 40% of premature deaths are attributed to personal behaviors, including patterns of eating and physical activity and decisions about smoking, drinking, illicit drug use, and sexual behavior...
