2014 n-type germanium has been irradiated with electrons of various energies in the range 0.5 to 3 MeV. Using transient capacitance measurements we observed four majority carrier traps associated with levels at 0.27 eV (E1), 0.39 eV (E2), 0.35 eV (E4), 0.32 eV (E5) below the conduction band. We have studied the variations of the introduction rates of these traps with the energy of irradiation. ...

The fact that several different human virus oncoproteins, including adenovirus type 9 E4-ORF1, evolved to target the Dlg1 mammalian homolog of the membrane-associated Drosophila discs-large tumor suppressor has implicated this cellular factor in human cancer. Despite a general belief that such interactions function solely to inactivate this suspected human tumor suppressor protein, we demonstra...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

Background and Purpose—Both stroke and the apolipoprotein E (APOE) e4 allele increase the risk of dementia. However, the interaction between stroke and APOE on dementia is still unclear. We addressed this topic by using a longitudinal design. Methods—We followed up a community cohort of 1301 subjects aged $75 years, who did not have dementia at baseline. Among them, 92 subjects had a history of...

Title: EXERCISE BEHAVIOR AND MAINTENANCE OF CEREBRAL CORTICAL ACTIVITY DURING COGNITIVE CHALLENGE IN MIDDLE-AGED MEN AND WOMEN GENETICALLY AT RISK FOR DEMENTIA: A MEGNETOENCEPHALOGRAPHIC STUDY Sean Patrick Deeny, Doctor of Philosophy, 2005 Directed By: Professor Brad Hatfield, Department of Kinesiology Exercise is known to protect and enhance cognitive function in normal aging through increased...

The submanifold Dirac operator has been studied for this decade, which is closely related to Frenet-Serret and generalized Weierstrass relations. In this article, we will give a submanifold Dirac operator defined over a surface immersed in E4 with U(1)-gauge field as torsion in the sense of the Frenet-Serret relation, which also has data of immersion of the surface in E4. Mathematics Subject Cl...

Nitrogenase is activated for N2 reduction by the accumulation of four electrons/protons on its active site FeMo-cofactor, yielding a state, designated as E4, which contains two iron-bridging hydrides [Fe-H-Fe]. A central puzzle of nitrogenase function is an apparently obligatory formation of one H2 per N2 reduced, which would "waste" two reducing equivalents and four ATP. We recently presented ...

Study of the infectious process of human papillomavirus type 11 (HPV-11) has been facilitated by the discovery that HPV-11-infected neonatal human foreskin epithelium can proliferate as xenografts into condyloma-like growths within athymic nude mice. Here we describe detection of HPV-11 infection of neonatal human foreskin-derived keratinocytes, infected and cultured entirely in vitro, by use o...
