Fission yeast rad22(+), a homologue of budding yeast RAD52, encodes a double-strand break repair component, which is dispensable for proliferation. We, however, have recently obtained a cell division cycle mutant with a temperature-sensitive allele of rad22(+), designated rad22-H6, which resulted from a point mutation in the conserved coding sequence leading to one amino acid alteration. We hav...
This work presents recent results of ongoing investigations into rotating spoke instabilities in Hall thrusters. Recent work by the authors demonstrated large amounts of electron current carried by spokes in the nearanode region in the H6 6-kW laboratory model Hall thruster, and raises the question of whether spokes may play a larger role in electron transport throughout the Hall thruster plume...
A(H5N1) virus, for which only 2 of the serum specimens we tested were positive (data not shown), but much lower than the seropositivity level for low pathogenicity avian influenza A(H9N2) virus; 3.4% of the samples tested were positive for A/Chicken/Hong Kong/ G9/1997(H9N2)–like virus (data not shown). A previous US study has reported H6N2-positive antibodies in veterinarians (9). Our results a...
by crowded roosting areas and sharing of roosts by multiple species. This behavior provides opportunities for transmission of Bartonella bacteria or exchange of infected ectoparasites, such as Cyclopodia spp. (8), although the precise roles of these 2 processes are unknown. Although no human cases of Bartonella spp. infection have been reported in Vietnam, Bartonella spp. have been identified i...
The study aims to see the effect of contribution, role, and venture capital on MSMEs business development, with quality human resources as a mediating variable. This research was conducted at Islamic banks in city Medan, sample 160 people. As for results obtained based path coefficient test carried out, it found that there were 3 significant items construction t-statistic values > 1.65 p-v...
Reaction of ethylidene-pyridyl functionalized bisphosphonates with vanadium containing oxo compounds has afforded three different bisphosphonate–polyoxovanadate derivatives, viz., [(VIVO2)(VV2O5)2{O3P-C(O)(CH2-2-C5NH4)-PO3}2]10– (1), [(VIVO2)(VV2O5)2{O3P-C(O)(CH2-3-C5NH4)-PO3}2]10– (2), [(VIVO)3(O){O3P-C(OH)(CH2-4-C5NH4)-PO3}3]8– (3), obtained in aqueous ammonium acetate buffer solutions (pH 4....
Thin Si films have been grown isothermally on Ge( 100) substrates using alternating exposures of Si,H6 and Si,C!16, maintaining chlorine and hydrogen surface termination. At 465 “C, film growth rate is roughly 2 monolayer per cycle (one cycle equals 1 Si,H6 and 1 Si,Cl, exposure). At 475 “C a uniform epitaxial film is obtained, while islanding is observed at higher T. This process is thermally ...
