1. The objective of the study was to compare the establishment and effect of Asaridia galli infections in 4 different layer-lines. 2. A total of 160 birds comprising 4 different commercial layer-lines, ISA Brown, New Hampshire, Skalborg and a cross of New Hampshire(NH) and Skalborg (Sk), were infected with A. galli eggs. The birds were examined for the presence of parasite eggs and parasites at...

recently there has been fabulous excitement in the nano-biotechnological area for the study of nanoparticles synthesis using some natural biological system, which has led the growth advanced nanomaterials. this intention made us to assess the biologically synthesized silver nanoparticles from the leaf of suaeda monoica (s.monoica) using 1 mm silver nitrate. the leaf extract of s.monoica incubat...

Microlensing events are now regularly being detected by monitoring the flux of a large number of potential sources and measuring the combined magnification of the images. This phenomenon could also be detected directly from the gravitational deflection, by means of high precision astrometry using interferometry. Relative astrometry at the level of 10μas may become possible in the near future. T...

Fish from Silver Stream reservoir in Newburgh, New York (USA) were examined in 1985 and 1986 following reports by fishermen who had found a high prevalence of skin lesions in brown bullheads Ictalurus nebulosus caught in the reservoir Oral and skin papillomas were found in 43.2 % and 60.0 O/o of the brown bullheads from these respective samplings, whereas no papillomas were found in yellow bull...

We present results from a high-resolution spectroscopic survey of 45 L dwarfs, which includes both very low-mass stars and brown dwarfs. Our spectra allow us to derive a significant number of new rotational velocities, and discover a slowly rotating (in projected velocity) L dwarf that allows more accurate measurement of spectroscopic rotations for these objects. We measure chromospheric activi...

primary or secondary hyperparathyroidism can present with a brown tumor of the mandible. involvement of other skull and facial bones is extremely rare. only a few cases with brown tumor of the orbital bones have been reported. an is year old girl with primary hyperparathyroidism presented with unilateral exophthalmos caused by brown tumor of the orbital roof, lite patient had a 1.5 cm palpable ...

Two new species of the genus Hisonotus are described from the upper Rio Tapajós basin, Mato Grosso State, Brazil. They are small species, growing up to about 30.0 mm SL, having the scapular bridge wide and totally exposed or having a small median pair of arrector fossae, and the abdomen completely covered with large plates in adult specimens (about 23.0 mm SL). They are distinguished from their...

We present high-speed, three-colour photometry of the eclipsing cataclysmic variable SDSS J150722.30+523039.8 (hereafter SDSS J1507). This system has an orbital period of 66.61 minutes, placing it below the observed “period minimum” for cataclysmic variables. We determine the system parameters via a parameterised model of the eclipse fitted to the observed lightcurve by χ minimisation. We obtai...

The discovery of active brown adipose tissue (BAT) in adult humans and the fact that it is reduced in obese and diabetic patients have put a spotlight on this tissue as a key player in obesity-induced metabolic disorders. BAT regulates energy expenditure through thermogenesis; therefore, harnessing its thermogenic fat-burning power is an attractive therapeutic approach. We aimed to enhance BAT ...

Eggs from 31-wk-old ISA-White and ISA-Brown hens were sampled immediately after lay and after periods of storage of 1, 3, 5, and 10 d at room temperature. Longer periods of storage resulted in lower albumen weight and albumen height and higher albumen pH. Eggs from ISA-Brown hens had more albumen and shell than those from ISA-White hens, likely due to differences in selection history rather tha...
