Radiation may be defined as the energy in form of electromagnetic waves or particles that pass through space and even heavy dense materials. The radioactivity is a continuously decreasing quantity which function half-life responsible radionuclides. natural sources radiation came from terrestrial radionuclides are widely distributed earth's crust. Field radiological surveys were conducted by GR-...

In hospitals, Acinetobacter baumannii is considered one of the major pathogens due to its antibiotic and antiseptic resistance capacity thus it persists in a stressed environment leads nosocomial infections. Its persistence influenced by biofilm development. This study looked at 60 A. isolates from four Iraqi hospitals. A significant distribution biofilm-forming characteristics was identified a...

AIM: Health-care-associated infections (HAI) are a serious patient safety problem. There effective preventive practices, but little information on adherence in AL-Anbar hospitals. This study aims to identify the practice association of health-care providers (HCPs) infection prevention with some sociodemographic characteristics. METHODS: A cross-sectional observational was conducted at different...

Let L(t) = 1+a1t+ · · ·+a2gt be the numerator of the zeta function of an algebraic curve C defined over the finite field Fq of genus g. We show that the coefficients ar of L(t) satisfy certain inequalities. Conversely, for any integers a1, . . . , am satisfying these inequalities and all sufficiently large integers g there exist curves of genus g, whose L-polynomial satisfies the following cong...

An increased prevalence of birth defects was allegedly reported in Iraq in the post 1991 Gulf War period, which was largely attributed to exposure to depleted uranium used in the war. This has encouraged further research on this particular topic. This paper reviews the published literature and provided evidence concerning birth defects in Iraq to elucidate possible environmental exposure. In ad...
