The major chromomeres of pachytene chromosomes 6 and 11 in the oocytes of Acheta (Orthoptera) are regions of amplification for ribosomal RNA cistrons (28 S and 18 S). During late prophase the amplified DNA copies are released from the chromomeres, which decrease in size as the amount of DNA decreases. The number of nucleotide pairs released from the major chromomere of chromosome 11 is about 1....

The failure and degradation mechanisms of gate-all-around silicon nanowire FET subjected to electrostatic discharge (ESD) are investigated through device modeling. Transmission line pulse stress test is simulated and device degradation physics is modeled. The device degradation level, interface state concentration and hard breakdown are shown and analyzed. From the model, we found that ESD stre...

This study explored the possibility that environmental estrogens in sewage effluent may reduce the reproductive fitness of adult male fish by suppressing their reproductive behaviors, including their ability to compete for nests and females. Male fathead minnows (Pimephales promelas) were exposed for three weeks to either blank control, effluent released by a sewage treatment plant (STPE), wate...

While the survival value of paternal care is well understood, little is known about its physiological basis. Here we investigate the neuroendocrine contributions to paternal care in the monogamous cichlid, Amatitlania nigrofasciata. We first explored the dynamic range of paternal care in three experimental groups: biparental males (control fathers housed with their mate), single fathers (mate r...

A low-cost high-efficiency wastewater treatment system for small communities up to ~500 p.e. is described. The treatment process comprises a septic tank, a secondary facultative waste stabilization pond and an aerated rock filter. For a wastewater flow of 200 litres per p.e. per day and a BOD contribution of 50 g per p.e. per day the expected final effluent quality is ~5 mg BOD, ~5 mg SS and ~4...

The human insulin gene has been previously localized to chromosome 11. We have analyzed the human DNA sequences present in a human-mouse somatic cell hybrid line possessing a translocation involving human chromosomes 11 and X. These data indicate that the human insulin gene is located on the short arm of chromosome 11 in the region p13 leads to pter.

background: killer cell immunoglobulin-like receptors (kir) are expressed on nk cells and a subset of t cells. the variable kir receptors along with their ligands, hla class i, influence risk for autoimmune and malignant diseases. objective: to investigate the kir gene profiles in relation to susceptibility to graves’ disease in patients with ophthalmopathy. methods: kir genes profiles were ana...

We compute the perturbative expansion of the Lattice SU(3) plaquette to β order. The result is found to be consistent both with the expected renormalon behaviour and with finite size effects on top of that.
