A combined process for temperature measurements in THM growth systems is described including the preparation of the source material as well as the liquid solution zone in one and the same ampoule. Using starting compositions with an excess of that component to act as the solvent the solution zone is formed during the travelling heater procedure. With thermocouples attached to the slightly modif...

Renin, a rate-limiting enzyme in the renin-angiotensin system, is regulated to maintain blood pressure homeostasis: renin gene expression in the kidney is suppressed in a hypertensive environment. We found that expression of a 15-kb human RENIN (hREN) transgene was aberrantly upregulated (>4.2-fold), while the endogenous mouse renin (mRen) gene was suppressed (>1.7-fold) in Tsukuba hypertensive...

Trihalomethane (THM) concentrations in blood and tap water were measured for 50 women living in two locations with different bromide concentrations and disinfectant types. Blood samples were taken from each woman early in the morning prior to any major water-use activity and again immediately after showering. Each residence was sampled for THMs in tap water prior to the woman's shower. Cobb Cou...

objective: investigating the dynamics of iranian nano-related publications form the ‎perspective of triple helix model (thm) is the goal of this research. ‎methodology: the data of nano-related publications collected from iranian isi ‎papers. this study maps the emergence of dynamics of knowledge base of ‎innovations using mutual information and transmission of uncertainty calculated ‎by thm. t...

representation of the physical layout. The algor i thm works on a set o f configurations constituting a constant size population. The transformations are performed through crossover operators that generate a new configuration assimilating the characteristics o f a pair o f configurations existing in the current population (similar to biological reproduction). Muta t ion and inversion operators ...

Bladder cancer has been associated with exposure to chlorination by-products in drinking water, and experimental evidence suggests that exposure also occurs through inhalation and dermal absorption. The authors examined whether bladder cancer risk was associated with exposure to trihalomethanes (THMs) through ingestion of water and through inhalation and dermal absorption during showering, bath...

BACKGROUND Evidence associating exposure to water disinfection by-products with reduced birth weight and altered duration of gestation remains inconclusive. OBJECTIVE We assessed exposure to trihalomethanes (THMs) during pregnancy through different water uses and evaluated the association with birth weight, small for gestational age (SGA), low birth weight (LBW), and preterm delivery. METHO...

Most people with epilepsy (PWE) live in developing countries with limited access to health care facilities. In sub-Saharan Africa with approximately 12 million PWE, 90% do not receive adequate medical treatment. In this context, traditional medicine, being easily accessible, plays an important role. However, in sub- Saharan Africa, studies on the attitude of people (both affected and not affect...

A comparison of two pitch detection algorithms using frequency domain analysis is presented. The algorithm showing the best results based on a perfomance evaluation done by a phonetician will be selected for use in an automatic speech recogni tion (ASR-) system based on the acoustic phonetic approach using knowledge-bases with an expert system. The first algori thm is the Seneff pi tch detectio...

G r i f f i t h s and Pet.rick (1965) propose several algori thms for recognizing sentences of contex t f ree grammars in the general case One of these algor i thms, the NBT (Non-select ive Bottom to Top) Algor i thm, has since been ca l led a " l e f t c o r n e r " algor i thm. Of l a te , i n te res t has been rekindled in l e f t co rne r parsers. Chester (1980) proposes a modi f ica t ion ...
