We present the current status of the improved Cascade-Exciton Model (CEM) code CEM2k and of the Los Alamos version of the Quark-Gluon String Model code LAQGSM. To describe fission and light-fragment (heavier than He4) production, both CEM2k and LAQGSM have been merged with the GEM2 code of Furihata. We present some results on protonand deuteron-induced spallation, fission, and fragmentation rea...

Entry into mitosis during the somatic cell cycle is regulated in response to signals that monitor the completion of DNA replication, the integrity of the nuclear genome, and, possibly, the increase in cellular mass during the cell cycle. It has been postulated that the operation of this cell cycle control involves the gradual accumulation of rate-limiting mitotic inducers, which trigger nuclear...

The production of radiostrontium in relatively high yield from fission reactions, together with the aflinity of strontium for bone, have added to the need for a quantitative understanding of the behavior of this element in the food chain leading to human bone. The quantity of this fission product which may be maintained in the bone tissue without perceptible damage to the organism is not well d...

The effect of detergents on giant unilamellar vesicles (GUVs) composed of phosphatidylcholine, sphingomyelin and cholesterol and containing liquid-ordered phase (l(o)) domains was investigated. Such domains have been used as models for the lipid rafts present in biological membranes. The studied detergents included lyso-phosphatidylcholine, the product of phospholipase A2 activity, as well as T...

Cell extracts, prepared from Nocardia restrictus, rapidly oxidize 3,4-dihydroxy-9,lO-secoandrosta-l,3,5(10)-triene9,17-dione with the consumption of 1 mole of oxygen per mole of substrate; no carbon dioxide is evolved. The reaction is stimulated by the presence of ferrous ions. The first product of ring fission has been identified as 4(5),9(10)-diseco-3 -hydroxyandrosta-l(lO),Z-diene-5,9,17trio...

In this paper is presented a discussion of fission induced in heavy elements (uranium) by protons with kinetic energies below about 400 MeV with the main emphasis on fission with protons of a few hundred MeV energy *. Thus, reactions where meson interference becomes of any importance are not considered. Even if fission is the main reaction in heavy nuclei this can not be discussed without consi...

Plant compounds that induced Arthrobacter sp. strain B1B to cometabolize polychlorinated biphenyls (PCBs) were identified by a screening assay based on the formation of a 4,4'-dichlorobiphenyl ring fission product. A chemical component of spearmint (Mentha spicata), l-carvone, induced Arthrobacter sp. strain B1B to cometabolize Aroclor 1242, resulting in significant degradation of 26 peaks in t...

This paper attempts to summarize the actual problematic of reactor antineutrino energy spectra in the frame of fundamental and applied neutrino physics. Nuclear physics is an important ingredient of reactor antineutrino experiments. These experiments are motivated by neutrino oscillations, i.e. the measure of the 13 mixing angle. In 2011, after a new computation of the reactor antineutrino ener...

Fissioncytorace-1, a member of the nasuta-albomicans complex of Drosophila is an evolutionary product of centric fission, which had occurred in the chromosome X3 of Cytorace 1, a hydridization product of Drosophila nasuta nasuta male (2n=8) and Drosophila nasuta albomicans female (2n=6). Cytorace 1 (males 2n=7; females 2n=6) has inherited this chromosome from its D. n. albomicans parent. The ch...

Gas chromatographic and mass spectrometric analyses of derivatized culture medium extracts were used to identify the products of flavonoid metabolism by rhizobia. A number of Rhizobium species and biovars degraded their nod gene-inducing flavonoids by mechanisms which originated in a cleavage of the C-ring of the molecule and which yielded conserved A- and B-ring products among the metabolites....
