In spite of the recognition of potentially toxic chemicals in chlorinated drinking water, few studies have evaluated reproductive health consequences of such exposure. Using data from a case-control study of miscarriage, preterm delivery, and low birth weight in central North Carolina, we evaluated risk associated with water source, amount, and trihalomethane (THM) concentration. Water source w...

A bstmct-A new efficient algorithm for bounded-distance decoding of the Leech la t t ice is presented. The algori thm decodes correctly at least ulp to the guaranteed error-correction radius of the Leech lattice. The proposed decoder is based on projecting the points of the Leech lattice onto the codewords of the (6,3,4) quar te rnary code, the hezacode Ne. Project ion on the hexacode induces p...

We propose a projection-based monolithic model order reduction procedure for class of problems in nonlinear mechanics with internal variables. The work is motivated by applications to thermo-hydro-mechanical (THM) systems radioactive waste disposal. THM equations the behavior temperature, pore water pressure, and solid displacement neighborhood geological repositories, which contain are respons...

In this paper, we consider a connected undirected graph with n nodes. An asynchronous dist r ibuted algori thm is described which determines a spanning tree of the graph. Moreover, if the edges of the graph are weighted, the same algorithm can compute a minimum-weighted spanning tree. This algori thm can be favourably compared to the one of Gallagher et al. [6] in the following way: identical a...

The disinfection by-product (DBP) formation was affected by the dissolved organic matter (DOM). Therefore, DOM properties and DBP potential of two most widely used source waters: groundwater (GW) surface water (SW), were comparatively studied in this work. results suggested that GW mainly consisted protein-like organics with smaller molecular weight (Mw) less than 3000 Da, while SW contained hu...

Hydrothermal carbonization (HTC) technology was used to carbonize and improve biomass raw material obtain hydrochar. The effects of HTC temperature holding time on the yield, composition, structure, combustion behavior, safety hydrochar were studied systematically. In addition, results show that with increase in prolongation time, yield gradually reduces, fixed carbon content increases, volatil...

We compute the index of contact p(Z; S)(c) of a set Z with a submanifold S at a point c 2 reg(Z \S) at which Z is normal pseudo-at along Z \ S (Thm 4.1, Cor. 4.4).

BACKGROUND Findings on water and total fluid intake and bladder cancer are inconsistent; this may, in part, be due to different levels of carcinogens in drinking water. High levels of arsenic and chlorinated by-products in drinking water have been associated with elevated bladder cancer risk in most studies. A pooled analysis based on six case-control studies observed a positive association bet...

Background: Trihalomethanes (THMs) occurring in public drinking water sources have been investigated in several epidemiological studies of fetal death and results support a modest association. Other classes of disinfection by-products found in drinking water have not been investigated. Aims: To investigate the effects of haloacetic acid (HAA) compounds in drinking water on stillbirth risk. Meth...
