We calculate the contributions of weak magnetism and proton recoil order O(Ee2?mN2)?10?5, i.e. to next-to-next-to-leading in large nucleon mass expansion, neutron lifetime correlation coefficients beta decay, where Ee mN are electron energy mass, respectively. analyze electron-energy angular distribution for decay with a polarized neutron, an unpolarized proton. Together Wilkinson’s corrections...

• Novel continuous catalyst thin-film of G-TiO 2 deposited on a ceramic membrane; G was used as additive to enhance the photocatalytic activity and barrier; The membrane fouling reduced by -UVA action; CECs rejection achieved values near 60% in flow mode operation; PMR able effectively reduce permeate toxicity zebrafish embryos. This work presents tubular coated with graphene-TiO nanocomposite ...

Among fishes, courtship behaviour and nesting defense are strong predictors of reproductive success. We conducted three experiments to assess the impacts of exposure to 17α-ethynylestradiol (EE2) on the ability of male fathead minnows (Pimephales promelas) to establish and defend a spawning territory. Fish were exposed to EE2 (2 or 8 ng L-1) for 27 days, while spawning conditions were gradually...

Steroid hormones have profound effects on the development and function of the nervous system. Environmental estrogens or xenoestrogens are manmade or are natural compounds, which mimics the action of estrogen hormones. The experimental evidence for impairment of cognitive functions in humans and mammals following exposure to xenoestrogens has been fiercely debated. The strongest arguments again...

We established an improved method for the determination of four estrogens including estriol (E3), 17beta-estradiol (E2), 17alpha-ethynylestrodiol (EE2) and estrone (El) in water. The method consisted of solid-phase extraction (0.5 L water) and subsequent analysis of analytes by ultra-performance liquid chromatography (UPLC) with an ultraviolet detector (UVD). Base-line separation was achieved f...

Marine sediment with an input of particulate organic matter was incubated to simulate the early aging process. On the sediment after various incubation periods, adsorption and desorption tests were conducted for three selected organic micropollutants: bisphenol A (BPA), 17α-ethinyl estradiol (EE2), and phenanthrene (Phe). The results showed significant sediment organic matter (SOM) decompositio...

contraceptive patches have become a frequently used contraceptive method. we present a mathematical model that describes the serum concentration profiles of norelgestromin (ngmn) and ethinylestradiol (ee) released from the contraceptive patch ortho evra®. we propose a simple one-compartment model based on pharmacokinetics data reported in previous studies. the model assumes a time-dependent rel...

OBJECTIVE To examine the effect of oxandrolone and the timing of pubertal induction on final height in girls with Turner's syndrome receiving a standard dose of growth hormone. DESIGN Randomised, double blind, placebo controlled trial. Setting 36 paediatric endocrinology departments in UK hospitals. PARTICIPANTS Girls with Turner's syndrome aged 7-13 years at recruitment, receiving recombin...

Thermal and hydrothermal biochars were characterized, and adsorption of bisphenol A (BPA), 17α-ethinyl estradiol (EE2) and phenanthrene (Phen) was determined to investigate the sorption characteristic difference between the two types of biochars. Thermal biochars were composed mostly of aromatic moieties, with low H/C and O/C ratios as compared to hydrothermal ones having diverse functional gro...
