background: among different pollutants released into the environment, dyes are considered as one of the most dangerous contaminants. in recent years, magnetic nanomaterials have attracted much attention for their dye removal capacity. the aim of this study was to explore the adsorption kinetics of an anionic dye (reactive orange 13 (ro)) by nife2o4 nanoparticles (nife2o4 nps) under various cond...

Serum levels of organochlorine pesticides (OCP) were measured in agricultural workers from Rio de Ja n e i ro St a t e , Bra z i l . Blood samples from 26 volunteers (24 males, 02 females, 1 7 60 years old) were taken in October 1997. OCP residues (op’DDT pp’ D D T, p p’ D D D, p p’ D D E, a l d r i n , d i e l d r i n , e n d r i n , h e p t a c h l o r, h e p t a c h l o re p ox i d e , α, βa...

This paper presents a novel design of a ring oscillator (RO) producing eight phases output with accurate signal phase adjustment. By using the pulse injection technique, the RO phase noise has been strongly suppressed. In addition, a novel phase control technique is proposed for the implementation of the phase modulation. The proposed RO achieves a phase noise of -131.5 dBc/Hz @1MHz offset and ...

The limits to sustained energy intake at peak lactation could be imposed peripherally, by the capacity of the mammary glands, or centrally, by the capacity of the animal to dissipate body heat generated as a by-product of processing food and producing milk. To distinguish between the two hypotheses, we examined milk energy output at peak lactation in MF1 laboratory mice exposed to 30 degrees C ...

mungbean (vigna radiata (l.) wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. in order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate rcbd (randomized complete block design) field experiment was carried ou...

In mammals, oestrogens generally stimulate adrenal function whilst androgens are inhibitory, and gestating females down-regulate their acute response to stressors in order to protect current reproductive investment. This study aimed to determine if adrenocortical function is similarly modulated by sex and reproductive status in the viviparous lizard, Egernia whitii. We compared the adrenocortic...

The effects of condensed tannins (CTs) extracted from five species of plants on egg hatching and larval development of Teladorsagia circumcincta (Stadelmann, 1894) (syn. Ostertagia circumcincta) were evaluated using in vitro bioassays. The extracts of CTs were obtained from Lotus pedunculatus (LP), Lotus corniculatus (LC), Dorycnium pentaphyllum (DP), Dorycnium rectum (DR) and Rumex obtusifoliu...
