The large number of failure in electrical power plant leads to the sudden stopping of work. In some cases, the necessary reserve materials are not available for maintenance which leads to interrupt of power generation in the electrical power plant unit. The present study, deals with the determination of availability aspects of generator in unit 5 of Al-Dourra electric power plant. In order to evaluate this generator's availability performance, a wide range of studies have been conducted to gather accurate information at the level of detail considered suitable to achieve the availability analysis aim. The Weibull Distribution is used to perform the reliability analysis via Minitab 17, and Artificial Neural Networks (ANNs) by approaching o

Background: It is becoming increasingly apparent that the study of infant cancer may lead to further understanding of the mechanisms of carcinogenesis, due to the unique clinical, genetic, and epidemiologic characteristics of cancer in infant.
Objectives: To study the clinical and pathological presentation of infants with cancer, their outcome and survival.
Patients & methods: A retrospective study was done over a 6 years period between (Jan.1st.2001- Dec. 31st. 2006), reviewed the records of 85 infants diagnosed and treated in oncology unit, children welfare teaching hospital, medical city-Baghdad.
Results: The majority of patients 57(67%) were from Baghdad & surrounding provinces; Leukemia was the most common type of c

Background: genital herpes simplex virus infection in pregnancy poses a major risk to the fetus and it has been associated with bad obstetric out come causing preterm labor, intrauterine growth retardation and spontaneous abortion. This study was conducted to determine if premature rupture of membranes before 37 weeks of gestational age are observed with subclinical shedding of herpes simplex virus (HSV).
Patients and methods: Cervical swabs were taken from 75 women with a history of preterm premature rupture of membranes before 37 weeks of gestation, and 20 women with normal
obstetrical history for the presence of HSV antigen using Enzyme linked Immuno Sorbent Assay (ELISA) method.
Results: HSV ant

   Chaotic features of nuclear energy spectrum in ⁶⁸Ge nucleus are investigated by nuclear shell model. The energies are calculated through doing shell model calculations employing the OXBASH computer code with effective interaction of F5PVH. The ⁶⁸Ge nucleus is supposed to have an inert core of ⁵⁶Ni with 12 nucleons (4 protons and 8 neutrons) move in the f5p-model space ( and ). The nuclear level density of considered classes of states is seen to have a Gaussian form, which is in accord with the prediction of other theoretical studies. The statistical fluctuations of the energy spectrum (the level spacing P(s) and the Dyson-Mehta (or statistics) are well described by the Gaussian orthogonal ens

OBJECTIVE: Synthetic vertebral body replacement has been widely used recently to treat different spinal conditions affecting the anterior column. They arrange from trauma, infections, and even tumor conditions. In this study, we assess the functional outcome of this modality in different spinal conditions. PATIENTS AND METHODS: Thirty-six cases operated from October 2010 to December 2017. Twelve patients had spinal type A3 fractures, 11 cases with spinal tuberculosis (TB), and 13 cases with spinal tumors. They were followed clinically for a mean period of 2.4 years. RESULTS: All the cases were approached anteriorly. Seven cases had a post-operative infection. No neurological worsening reported. We had dramatic neurologic
