After 10 years of steadily increasing the experimental precision at LEP/SLC, there is a strong demand on an update of existing programs for fermion pair production. We present a rederivation of the O(α) Bremsstrahlung corrections to e + e − → ¯ f f for the semi-analytic program ZFITTER. We focus on observables like total cross section and forward-backward asymmetry in the leptonic case with com...

ABSTRACT: Growth hormone (GH), insulin-like growth factor 1 (IGF1), and leptin (LEP) can be candidate genes for association studies because they play vital roles in the metabolism process. Thus, this study aimed to identify variants these associated with body traits Santa Ines sheep. The following were recorded: weight at 100 (BW100) 240 days (BW240), average daily gain (ADG), withers (WH) crou...

The effects of different parameters and the nitric acid concentration on sensitivity repeatability elemental analysis were characterized for liquid electrode plasma optical emission spectrometry (LEP-OES). In addition, internal standardization LEP-OES was investigated. developed method used determination lithium, potassium, iron, zinc in aqueous solutions samples with high concentrations after ...

The protection system used to shield LEP experiments against particle backgrounds has been upgraded in view of the much higher photon background rates expected at LEP2 energies. General experience with background rates in the LEP experiments at highest beam energies is reported and special features are highlighted.

Two serotyping schemes (Penner and Laboratory of Enteric Pathogens [LEP]) based on soluble heat-stable antigens were used to analyze 3,788 Campylobacter sp. isolates. A significant percentage (36.6%) was untypeable using LEP serotyping; greater cross-reaction was also observed. The relative discrimination capabilities of the techniques were similar. Penner serotyping fulfils more of the requisi...

Results on LEP 2 e + e − → f f and γγ(γ) production are presented. These are compared with Standard Model predictions, and then used to set limits on various New Physics models, including Low Scale Gravity. Finally the status of the LEP beam energy determination from radiative return events is summarised.

The Scottish Government’s ambitious 1?+?2 Language Strategy has refocused attention on language education policy (LEP) and the provision for learning additional languages in schools. Howev...

Mahoganoid (Mgrn1(md)) is a mutation of the mahogunin (Mgrn1) gene. The hypomorphic allele suppresses the yellow pigmentation and obesity of the A(y) mouse that ubiquitously overexpresses agouti signaling protein (ASP). To assess the physiological effects of MGRN1 on energy and glucose homeostasis, we generated animals doubly mutant for Mgrn1(md) and A(y), Lep(ob), or a null allele of Mc4r, and...

In yeast, the differentiation process at the end of meiosis generates four daughter cells inside the boundaries of the mother cell. A meiosis-specific plaque (MP) at the spindle pole bodies (SPBs) serves as the starting site for the formation of the prospore membranes (PSMs) that are destined to encapsulate the post-meiotic nuclei. Here we report the identification of Ady3p and Ssp1p, which are...

Leptin and leptin receptor genes are considered as production traits markers in dairy or beef cattle. The aim of this study was to verify the associations of polymorphisms in bovine LEP and LEPR genes with production and reproduction traits in Slovak Spotted and Pinzgau cows. Long-life production was evaluated: milk, protein, and fat yield and reproduction traits: age at first calving, calving ...
