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...

The objective of this investigation was to examine the effectiveness of a magnetic ion exchange resin (MIEX) to enhance the coagulation of disinfection by-product precursors in nine surface waters, each representing a different element of the USEPA's 3 x 3 enhanced coagulation matrix. The effect of MIEX-pretreatment on the requisite alum dose needed for subsequent coagulation of turbidity was a...

The effects of L-158,809, an angiotensin II type 1 receptor antagonist, on cardiac hypertrophy and nephropathy were examined using Tsukuba hypertensive mice (THM) carrying both human renin and angiotensinogen genes. Nine male THM aged 20 weeks were assigned to each of a no-dosage group and an L-158,809 dosage group, and L-158,809 was administered for 8 weeks. Nine age-matched male C57BL/6 mice ...

In this paper , we prove the first approximate max-flow min-cut theorem for undirected mul t i commodi ty flow. We show tha t for a feasible flow to exist in a mul t icommodi ty problem, it is sufficient t ha t every cut ' s capacity exceeds its demand by a factor of O(logClogD), where C is the sum of all finite capacities and D is the sum of demands . Moreover, our theorem yields an a lgor i t...

As fontes que abastecem o sistema público de água em Florianópolis, Santa Catarina-Brasil são muito diversificadas e foram usadas na investigação da formação de trihalometanos (THM). Os resultados obtidos apresentaram relação com os mananciais onde são feitas as captações de água. Nos mananciais onde há maior contato com vegetação a quantidade de trihalometanos totais (TTHM) foi maior. As amost...

In this article, superstitions prevailing in India. attached to medicinal plants have been compiled. The author opines that there must be some rationale behind each of these superstitious practices which merits painstaking study to understand thm in the proper perspective.
