When nitrate is used in a biological electron transport
system as the final acceptor of hydrogen to form water,
the system is characterized as "Nitrate Respiration." However,
the quantitative expression of the over-all participation
of NO₃⁻(0) in the oxidation of glucose by denitrifiers
such as Pseudomonas stutzeri deserves clarification.

Background: Heart morphogenesis involves chamber formation followed by septation. Septation is the remodeling of the heart from a single channel peristaltic pump to a two channel pump with one-way valves. Several transcription factors have been implicated in the development of congenital cardiac defects. The paired-like homeodomain transcription factor Pitx2 has...
Solar thermal energy can be stored and later converted to electrical energy using a combination of thermochemical energy storage (TCES) and a thermoelectric generator (TEG). This TEG and TCES combination illustrates a potential route for clean electricity storage from renewable energy. TCES allows for thermal energy from the sun to...
Alaska encompasses several climate types because of its vast size, high-latitude location, proximity to oceans, and complex topography. There is a great need to understand how climate varies regionally for climatic research and forecasting applications. Although climate-type zones have been established for Alaska on the basis of seasonal climatological mean...
The purpose of this study, to examine the relevance of U.S.
graduate education in agriculture to careers in agricultural
development of East African agriculturalists, was examined in
terms of three problems:
Problem 1: Was U.S. graduate education in agriculture
relevant to careers in agricultural development of East
African agriculturalists?
Problem...
Ecotourism is recognized for its economic potential to reduce poverty in least developed countries. There is a general belief that ecotourism will benefit local development, but previous research has found mixed results. This paper explores the idea of ecotourism and its impact on local sanitation in Nepal’s Annapurna Conservation Area....
A differential current-mode track-and-hold (T/H) amplifier is used to sample an analog input signal. A new closed-loop current-mode architecture has been developed that overcomes the stability problems associated with closed-loop architectures. The T/H circuit has been fabricated in a 0.35-μm quad-metal, double-poly CMOS process. The measured total harmonic distortion (THD)...
