Biliary excretion of cadmium was studied in two groups of five rats which were given repeated injections of 109Cd. The first group was given a total amount of 6 mg Cd/kg which was 6 times as much as the second group. The elimination of cadmium in bile, urine, and feces was measured 4 to 5 weeks after the last injection. The relative biliary excretion of cadmium was the same in both groupetion, ...

Clusters are geographically close groups of related companies or institutions related to a certain area which are inherently more efficient than the other companies due to advantages such as being located in one place, networks, external knowledge, variability of human capital, etc. Today, development through clusters plays a pivotal role in the economic and industrial policies of developed...

Local bioenergy will play a crucial role in national and regional sustainable energy strategies. Effective siting and feedstock procurement strategies are critical to the development and implementation of bioenergy systems. This paper aims to improve spatial decision-support in this domain by shifting focus from homogenous (forestry or agricultural) regions toward heterogeneous regions—i.e., ar...

In a recent paper, for “large” (but otherwise unspecified) subsets A,B, C,D of Fq, Gyarmati and Sárközy (2008) showed the solvability of the equations a + b = cd, and ab + 1 = cd with a ∈ A, b ∈ B, c ∈ C, d ∈ D. They asked whether one can extend these results to every k ∈ N in the following way: for large subsets A,B, C,D of Fq, there are a1, . . . , ak, a1, . . . , ak ∈ A, b1, . . . , bk, b1, ...

Forest cover transitions in the developing tropics are conditioned by agricultural change. The expansion, intensification, and diversification of agricultural land uses are tied to regional economic/environmental regimes and decisions of local farming households. Land changescienceandagrariansystems research sharean interest in the drivers of household strategies, land use impacts, and typologi...

The causes of amyotrophic lateral sclerosis (ALS) are largely unknown, and may always be multiple, including environmental factors. Monogenetic determinants of ALS are involved in roughly 20% of all cases (including 10% familial cases). Less well understood multigenetic causes may contribute to another 20% to 80%. Environmental factors likely play a role in the development of ALS in susceptible...

A myotrophic lateral sclerosis (ALS) is a progressive and often fatal neuromuscular disease. Most people die within 2–5 years of being diagnosed with ALS (Mitsumoto, Chad, & Pioro, 1998). Community concerns about perceived clusters of cases of ALS have challenged public health agencies to consider the possible contribution of environmental contaminants to the development of this disease. The ge...
