Calculation of the atomic properties of excited states for B-atom using Hartree Fock approximation

In this paper were studied some atomic properties for Boron atom and like ions such as ( C+1 and N+2) for different excited states( where nequal (3,4,5). This system consists of five electron : two electron each in(1S,2S-Level) with same quantum number except spin component ,where the first electron with spin up (α)and the other down(β) and the Fifth electron puts in(n S-Level)with spin up(α).using Hartree Fock approximation in position spaceand electron density at the nucleus Ï(0) have been calculated for these states of the same atom

Effect of Thickness to the Structure Properties of CdO Thin Films

In this paper CdO thin films were prepared by using chemical bath deposition method. Three different thicknesses of CdO films (84.1nm, 165.1nm, 194.23nm) were used .x-ray diffraction technique has confirmed the formation of cadmium oxide, where reveals the changes in films structure with thickness increase. Many structural properties and constants have been studied and calculated by using the formation from XRD patterns and ASTM chart such as grain size, FWHM, integral breadth, shape factor, texture coefficient, and number of layers .These structural constants were plotted as a function of the films thicknesses. The results indicate that the high grain size (21.557nm) which was calculated for crystalline plane (111) was corresponding to the high film thickness (194.23nm), while larger number of layer obtained for the film thickness 165.2nm

Prevalence of pneumovagina among subfertile Arabian mares in Al-Najaf province / Iraq

This study was conducted in Al-Najaf province / Iraq during 2016 on 51 Arabian subfertile mares to assess the prevalence of pneumovagina. The cases classified according to caslick’s index, and out of 51 examined mares there were 21 (41.17 %), 18 (35.29 %), and 12 (23.52%) mares for grade I, II and III respectively. Moreover, the correlation between the animal’s age and the mean of caslick’s index, the results showed that there were 64 (15.68 %), 72 (25.49%) and 98 to 123 ( 35.29% to 23.52 %) for age groups 3-7 years, 7-10 years and more than 18 years respectively. The ultrasonic examination revealed that the mares in grade I mares showed a higher percentage of reproductive system abnormalities and the percentage of was Endometritis (14.28%). While, in mares with grade II, the percentages of vaginitis, Cervicitis, Endometritis, Pyometra and anovulatory follicles, were 22.22 %, 0 %, 38.88 %, 33.33% and 5.55 % respectively. At the same time, the percentages of vaginitis, Cervicitis, Endometritis, Pyometra and anovulatory follicles were 16.66 %, 16.66 %, 0 %, 58.33% and 8.33% respectively the mares with grade III. In conclusion, the results of the present study revealed the prevalence of mare subfertility in mares due to pneumovagina. The author recommend more future studies to correlate between the prevalence of pneumovagina and the causes of uterine infection in mare

Field Evaluation to the attraction efficiency for the different sources of the red palm weevil aggregation pheromone

Field experiments were conducted during the periods from June, 2014 to March, 2015, in three date palm orchards located in Al Ain city, Abu Dhabi, United Arab Emirates, in order to evaluate the attraction efficacy for five different sources from the red palm weevil (RPW), Rhynchophorous ferrugineus Oliver (Coleoptera: Curculionidae), aggregation pheromone by using the standard four window black bucket trap.  The three orchards are characterized by having different levels of infestation incidence by red palm weevil. The Randomize Complete Block Design (RCBD) with five treatment and three replicates was used in each of the three orchards. The aggregation pheromone sources used in this experiment were: Rhyfer 700, Pherocon RDPW Lure, Ferrugitom 700, Weevil lure, and Ferrulure +. Collectively in the three farms as well as per each farm, Weevillure aggregation pheromone trap capture significantly lower average numbers of RPW adults than Rhyfer, Pherocon, Ferrulure, and Ferrugitom pheromone sources. Rhyfer pheromone is about 1.12, 1.18, 1.56 & 1.16 % more efficient than Pherocon, Ferrugitom, Weevillure & Ferrulure, respectively

Search for jet extinction in the inclusive jet-pT spectrum from proton-proton collisions at s=8 TeV

Published by the American Physical Society under the terms of the Creative Commons Attribution 3.0 License. Further distribution of this work must maintain attribution to the author(s) and the published articles title, journal citation, and DOI.The first search at the LHC for the extinction of QCD jet production is presented, using data collected with the CMS detector corresponding to an integrated luminosity of 10.7  fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Improvement of Fatigue Property in High Strength Aluminum Alloy by Shot Peening

Shot peening process has both the beneficial and detrimentaleffects; therefore, it is difficult and time–consuming task to determine the optimized process parameters based on the fatiguelife. In this study the fatigue of 7001-T6 high strength aluminum alloy has been investigate before and after a shot peeningis beneficial for a treatment to investigate where a shot peening is beneficial for a component with this combination. The effect of 12 min. shot peening on the fatigue behavior of the material used gave an increase in the fatigue life of up to 2.49 times depending on the applied stress, and a 28.34% increase in the endurance limit of the material. Cumulative fatigue damage was conducted under low-high and high-low stress amplitude .The fatigue life prolonging factor (FLPF) was calculated for different stress amplitudes and it was found that this parameter is an indicator for prolonging the fatigue life.</jats:p
