A multivariate statistical clustering technique—based on the iterative k-means algorithm of Hartigan (Hartigan 1975)—has been used to extract patterns of climatological significance from 200 years of general circulation model (GCM) output. Originally developed and implemented on a Beowulf-style parallel computer constructed by Hoffman and Hargrove from surplus commodity desktop PCs (Hargrove et...

Despite Denmark’s limited size of just 44,000 sq km, the country produced 22 million pigs, 137 million broilers and 595,000 cattle in 2001. Denmark has approximately 14,000 swine producers, 95% of whom are members of the 150-year-old nationwide producer cooperative, the Danish Bacon and Meat Council. With a human population of 5.3 million inhabitants, domestic consumption accounts for only 15% ...

Introduction The South Pacific Island region covers an area of 525,000 sq. km. with a total population of six million (predicted to rise to 12 million in 30 years time). The whole Pacific region is composed of a vast number of islands which vary in size from Papua New Guinea with a population of around four million, to Niue with a population of less than 2,000. Although not similar in terms of ...

Tsetse flies (Glossina sp.) infest over 11 million sq km of Africa, and are vectors of Trypanosomosis (or Trypanosomiasis) in both man and domestic livestock. For example, it is estimated that tsetse occur over 7% of Zimbabwe and 60% of Tanzania and Trypanosomosis has an important negative impact on livestock production in these areas. In addition to the use of trypanocidal drugs, control, of T...

Hussainsagar lake in the heart of Hyderabad city receives domestic sewage and industrial effluents through five streams draining the catchment area of 245 sq. km around the lake. Lake used to receive untreated industrial effluents through streams during 1970 -1990. Over the years, sediments in the lake have adsorbed the heavy metals and have reported elevated concentrations. Metal speciation of...

In this paper, the severity prediction of drought through the implementation of modern sensor networks is discussed. We describe how to design a drought prediction system using wireless sensor networks. This paper will describe a terrestrial interconnected wireless sensor network paradigm for the prediction of severity of drought over a vast area of 10,000 sq km. The communication architecture ...

We identified that the chemical linkage of the anticancer drug doxorubicin onto squalene, a natural lipid precursor of the cholesterol's biosynthesis, led to the formation of squalenoyl doxorubicin (SQ-Dox) nanoassemblies of 130-nm mean diameter, with an original "loop-train" structure. This unique nanomedicine demonstrates: (i) high drug payload, (ii) decreased toxicity of the coupled anticanc...

Polychlorinated biphenyls (PCBs) exert a broad range of toxicity via both parent compounds and their metabolites. Our previous study showed that hydroquinone (H2Q) metabolites of PCBs act as cosubstrates for prostaglandin H synthase (PGHS), and are oxidized by this enzyme to corresponding quinones (Q). The goal of this thesis is to illuminate the PGHS-mediated toxicity of lower chlorinated PCBs...

In order to increase the accuracy of diagnosis in lung cancer, analysis concerning cytological and histological correlation was attempted. The present study consists of 106 patients, who were seen during the past approximately five years and underwent radical surgery to remove tumors completely; mere biopsy specimens were excluded. These patients were 63 years old on the average, 78 males and 2...
