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.

I:n this paper, we describe a new corpus-based approach to prepositional phrase a t t achment disambiguation, and present results colnparing peffo> mange of this a lgori thm with other corpus-based approaches to this problem.

We report the formation of trihalomethanes and other disinfection by-products from four polyfunctional terpenoids during simulated chlorination of natural waters. Complex suites of products were identified by closed loop stripping analysis (CLSA)/gas chromatography-mass spectrometry (GC-MS) from halogenation of beta-carotene and retinol. beta-Ionone appeared to be a key intermediate in the halo...

OBJECTIVES To report trihalomethane (THM) and haloacetic acid (HAA) concentrations in drinking water, assess variations in these concentrations depending on source and over time, and estimate individual intake during pregnancy. METHODS Water taken from 33 representative points of the water supply network of the 25 municipalities in the study area was analyzed from 2006-2008. Water drinking ha...

Over 1.1 billion people in the world lack access to improved drinking water. Diarrheal and other waterborne diseases cause an estimated 2.2 million deaths per year. The Safe Water System (SWS) is a proven household water treatment intervention that reduces diarrheal disease incidence in users in developing countries. Because the SWS recommends the addition of sodium hypochlorite to unfiltered w...
