The objective of this study was to assess whether the increase of NOM (natural organic matter) reported for natural waters in various countries could be observed for Suezenvironment water resources. Long term data for TOC, oxidability, colour, turbidity and other physico-chemical parameters were retrieved from 23 sites mostly in France (18), UK (3), Germany (1) and North America (1). Evolution ...

Natural organic matter (NOM) is a major water constituent that affects the performance of drinking water treatment processes and the quality of drinking water. Besides, several studies have shown that NOM can be adsorbed on the surface of oxides being thereby able to compete with other ions. The overall goal of this study was essentially to investigate the competitive adsorption between fluorid...

The present study explored which underlying motivations induced people to participate in a television exercise program called "The Netherlands on the Move!-television" (NOM-tv). A cross-sectional study was carried out among 1,349 viewers of NOM-tv. The respondents completed the intrinsic motivation inventory (IMI), assessing their levels of intrinsic motivation towards participating in the NOM-...

HYPOTHESIS Nonoperative management (NOM) of injuries to the liver, spleen, and kidney is highly successful, as shown in retrospective studies, but needs prospective validation. Patients in whom NOM is likely to fail can be identified by specific criteria. DESIGN Prospective observational study. SETTING Academic level I trauma center at a county hospital. PATIENTS Two hundred six patients ...

by Xiaorong Xiang Natural organic matter (NOM), a heterogeneous mixture of molecules, plays a crucial role in the evolution of soils, the transport of pollutants, and the change of global weather. The evolution of NOM over time is an important research area in biology, geochemistry, ecology, soil science, and water resource. Due to its complexity and the structural heterogeneity, new simulation...

Natural organic matter (NOM) enhancement of the biological reduction of hematite (alpha-Fe2O3) by the dissimilatory iron-reducing bacterium Shewanella putrefaciens strain CN32 was investigated under nongrowth conditions designed to minimize precipitation of biogenic Fe(II). Hydrogen served as the electron donor. Anthraquinone-2,6-disulfonate (AQDS), methyl viologen, and methylene blue [quinones...

Ozone is widely used to disinfect drinking water and wastewater due to its strong biocidal oxidizing properties. Recently, it was reported that hydroxyl radicals ((.)OH), resulting from ozone decomposition, play a significant role in microbial inactivation when Bacillus subtilis endospores were used as the test microorganisms in pH controlled distilled water. However, it is not yet known how na...

The Linnaean taxon Titanoptera is a distinctive Triassic insect order the origin of which is uncertain. Forewing venation patterns of the Permian Linnaean subfamily Tcholmanvissiinae (Orthoptera) and of the Titanoptera are re-investigated. The comparative analysis supports the view that the morphology of the latter group is derived from that of the former. As a consequence, the order Titanopter...
