Lactate dehydrogenase A4 (LDH-A4) was purified for yak skeletal muscle. Michaelis constant (Km) analysis showed that yak LDH-A4 for pyruvate was significantly higher than that of cattle. cDNA cloning of LDH-A revealed two amino acid substitutions between yak and cattle. We suggest that the higher Km of yak LDH-A4 might be a result of molecular adaptation to a hypoxic environment.

BACKGROUND An increasing risk of Schistosoma mansoni infection has been observed around Lake Victoria, western Kenya since the 1970s. Understanding local transmission dynamics of schistosomiasis is crucial in curtailing increased risk of infection. METHODOLOGY/PRINCIPAL FINDINGS We carried out a cross sectional study on a population of 310 children from eight primary schools. Overall, a total...

Today, over 90 percent of world trade is carried out via maritime transportation by 90,000 vessels. Like all modes that use fossil fuels, ship emissions significantly contribute to global climate change and acidification. In this aspect, the shipping industry responsible for a significant proportion problem. According data International Maritime Organization (IMO), more than 3% carbon dioxide c...

in this article, rubber bumpers of double - wishbone suspension system have been modeled and analyzed. the objective of the present work is to predict the performance of these products during deformation, represent an optimum method to design, obtain stiffness characteristic curves and utilize the results in the automotive suspension dynamic analysis. these parts are nonlinear and exhibit large...

This paper deals with nonparametric density estimation on $\mathbb{R}^2$ from i.i.d. observations. It is assumed that after unknown rotation of the coordinate system coordinates observations are independent random variables whose densities belong to a Hölder class parameters. The minimax and adaptive theories for this structural statistical model developed.

IN T R O D U C T IO N Bridges are an integral part of any highway system. The design of a particular bridge depends on many variables. A major considera­ tion, often necessary, is the length of the bridge. In certain circum­ stances and locations the length may be dictated by factors other than cost. But, where necessary the designer must decide, “How far can the bridge approaches extend onto t...

Knowledge Management is frequently cited as one enabler of firm innovation especially among Western corporations. There is scant reported research that supports for such empirical links especially in the Malaysian context. There is a need for local research to address the KM practices, concepts, instruments, and effects. Using data from 149 Malaysian large manufacturing firms, a KM practices su...

Inland waterway networks are likely to go through heavy changes due to a will in increasing the boat traffic and to the effects of climate change. Those changes would lead to a greater need of an automatic and intelligent planning for an adaptive and resilient water management. A representative model is proposed and tested using MDPs with promising results on the water management optimization. ...

In recent years, single object tracking has been extensively studied and achieved much development. However, multiple objects tracking is still an issue that remains to be addressed. Generally speaking, existing multiple objects tracking methods employ a manner of simultaneously tracking each object respectively. In this paper, we develop a multiple ship tracking algorithm based on deformable p...
