The isolated North Atlantic island of Bermuda, lying 1000 km ESE of Cape Hatteras, North Carolina, USA, has received scant attention from bryologists since the last compilations of nearly a century ago (EG Britton, 1918; Evans, 1918), plus a few additions (Andrews, 1923; Dixon, 1936). Of the mosses listed by EG Britton (1918), those that are not widespread in both Europe and North America are o...

background: male infertility is affected by several factors. lead is one of the heavy metals more bioavailable than usually modifies the sperm quality in humans. objective: the aim of this study was to establish the role of lead in semen quality in environmentally exposed men. materials and methods: semen and blood samples were obtained from two groups: the exposed group (eg=20) and the non-exp...

We report the discovery of a partial ∼ 2 diameter non-thermal radio shell coincident with Taz, the pulsar wind nebula (PWN) in the error box of the apparently variable γ-ray source 3EG J1809−2328. We propose that this radio shell is a newly identified supernova remnant (SNR G7.5−1.7) associated with the PWN. The SNR surrounds an amorphous region of thermal X-rays detected in archival ROSAT and ...

We report the synthesis and application of a novel Exfoliated graphite/Selenium-Zinc oxide (EG/Se-ZnO) nanocomposite for photodegradation of methylene blue dye and its antibacterial activity. The composite was characterized using XRD, FTIR, SEM and TEM. Applicability of EG/ Se-ZnO nanocomposite as photocatalyst was investigated by the photocatalytic degradation of methylene blue as a model for ...

This study explored the effects of GnRH agonist (GnRHa) immunity on expression of FSHR mRNA in pituitary and FSHR protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (EG) during anestrus season. Animals in EG-I, EG-II and EG-III were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...
