In order to quantitatively and qualitatively evaluate soybean yield under conditions of reducing the amount of irrigation water, a field experiment was carried out according to the design of the randomized whole lots with four replicates and four treatments in Moara Dominica in Romania in 2015 included four irrigation levels and as follows the first treatment (T1) with a decrease of 40 % Of the water requirement and treatment (T2), a decrease of 20% of the water requirement. As for the treatment (T3), irrigation was carried out according to the water requirement and the fourth treatment (T4), irrigation was carried out using a 20% increase over the water requirement. The study included in addition to the grain yield, the measurement of the biological yield, the weight of dry stems, pods, protein, protein and oil yield and water efficiency. The highest and lowest quantities of cereals were recorded 1950 kg. h-1 and 1085 kg. h-1 in T4 and T1 respectively. Reducing the amount of irrigation water results in a decrease in the crop yield and the percentage of oil in the seeds. The rate of oil decrease in seeds was more severe compared to other indicators. The oil yield in transactions (T2) and (T1) decreased significantly compared to the control treatment (T3).
Water productivity indicators showed a clear effect of the amount of irrigation water on all indicators of this study. Depending on the efficient use of water we can conclude that T2 was the best treatment compared to other treatments.

This study investigates the effects of changes of laser ablation energy parameters on the structural and optical properties of colloidal gold nanoparticles (AuNPs) prepared using pulsed Nd:YAG laser system at wavelength 1064 nm of highly purified solid targets of Gold noble elements plate in distilled water and studying the effects of colloidal AuNPs on the viability of MCF-7 cancer cell lines. Different laser ablation energies (500, 600, 700 and 800) mJ at a fixed number of laser pulses of (100) pulses were used to prepare colloidal AuNPs nanoparticles. The optical and surface morphological characteristics of AuNPs were studied using UV-Vis Spectroscopy, and Field Emission Scanning Electron Microscopy (FE-SEM). The results of UV-Vis absorption spectra showed an individual absorption peak in the visible region for the colloidal AuNPs solutions which appeared at (523-529) nm. Also, UV-Vis Spectroscopy results showed an increase in intensity of the absorption peaks and the concentrations of the materials.
The color of AuNPs solution was also changed from light to dark red with the increase in energy of the laser ablation. The results showed that the peaks of the surface Plasmon resonance peaks were shifted towards the longer wavelengths (converted to the red color). FE-SEM and TEM images analysis showed that most nanoparticle diameters were within the nanoscale. An increase in the average nanoparticle diameter was obtained with the increase of the laser ablation energy. The morphology of nanoparticles was almost spherical and homogenous with some agglomeration. The colloidal AuNPs showed concentration-dependent manner on the growth of MCF-7 breast cancer cells with IC50 value of about 12.98 mg/L.

The ground state charge and matter density distributions, the corresponding root mean square (rms) radii and the elastic electron scattering form factors for some sd-shell nuclei (such as 23Na, 25Mg, 27Al and 29Si nuclei) are studied by the radial wave functions of the harmonic oscillator (HO) and Woods-Saxon (WS) potentials. The calculated results are discussed and compared with the experimental data. It is found that the calculated results of charge and matter density distributions are in very good agreement with the experimental data.

Multi-objective optimization also known as multi-objective programming is an area of multiple criteria decision making that is concerned with mathematical optimization problems involving more than one objective function to be optimized simultaneously. In such circumstance, we have to be discovered out compromise arrangement which is ideal for all the objectives in a few senses. In this paper, we transformed multi-objective linear plus linear fractional programming problems to single QPP and then solved by methods of QPP. Illustrative numerical examples are displayed for exhibit reason. We have explored an arrangement to the MOLPLFP issue based on a hypothesis already considered by Dinkelbach. He clearly delineated a calculation for fractional programming with nonlinear as well as linear terms within numerator and denominator.

Molluscum Contagiosum virus (MCV), a double strand DNA virus that belongs to the Poxviridae family, MCV causes pearl disease. Seventy-five lesion samples were collected in Diyala province at dermatology clinics, from 30 September to 20 October 2019 from patients with Molluscum Contagiosum Virus after diagnosis by the specialist doctor, and further 25 samples were curreted frm skin as a control group collected from healthy. After viral genome extraction, specific primer was detected by conventional PCR then sequencing PCR then sequencing finaly registeration in NCBI and phylogenitic tree. Phylogenitic tree was generated to evlute the viral evalution and closest neighbour. The results of the PCR for control group (25 samples) were negative for all. From 75 samples only 7 samples were positive with specific bands at 393bp (9.3%) while 3 samples with specific bands at 393bp and nonspecific bands at 300bp (4%). Then samples with specific bands at 393bp that were divided into two groups according to similarity after sequencing. It was found that the matched rate was 100% when comparing each of these groups with the global isolates in NCBI. Two isolates were registered at NCBI with the accession number for the recorded isolates were LC520237 and LC520238.

In this work, ceramic crude petroleum filter was prepared from low-cost materials based on Kaolin powder and Alumina, with combustible materials as palm fronds powder which acts as pore creating the agent. The filter samples with different content (5,10,15,25,35 and 45) % of palm fronds were fabricated using a dry pressing method and fired at1100 ˚C. After that, samples of porous ceramic filters were prepared and some tests were carried out, such as characterization by X-ray diffraction, physical properties (linear shrinkage, mass loss) and mechanical properties (compressive strength and diametrical strength). Results showed that linear shrinkage was 7.7%, loss in mass was 49.4%, compressive strength was 2.2 Mpa and diametrical strength was 1.7 Mpa with a 45% ratio of fine (P.F). Crude petroleum passing through the filters evaluated by tests, such as (API Gravity, Sulfur Content and Asphaltenes Content). The result of API Gravity before immersion crude petroleum filter balls was 24.70 and after immersion crude petroleum filter balls for 14 days for 30% (P.F) increased to 32.5. Sulfur Content before immersion crude petroleum filter balls was 3.76 and after immersion crude petroleum filter balls for 14 days for 30% (P.F) decreased to 2.6.So Asphaltenes Content before immersion crude petroleum filter balls was 6.68 and after immersion crude petroleum filter balls for 14 days for 30% (P.F) decreased to 1.6.

Undoped and Aluminium (Al) doped ZnO thin films with different weight percentages (0, 2, 4, 6, 8%) were deposited on glass substrates using “sol-gel spin coating method”. Optical, Crystal structural and surface morphological characteristics of all prepared samples have been studied in terms of their doping effects. The crystal structural analysis was done by X-ray diffraction, and the results showed that all prepared films have “polycrystalline hexagonal” type structure with preferred orientation along (002) for all films except for the percentage (4%) where its preferred orientation was (101). The Al doping leads to decrease the crystallite size of ZnO thin films. Other structural properties such as lattice constant, texture coefficient, dislocation density and number of crystalline per unit area for all prepared films have been calculated. (FE-SEM) images results showed that all prepared films were in the range of (10-100nm) scale nanostructure. Also, the values of average grain size decrease and the surfaces became more homogenous with increase of Al doping ratio. The optical results showed that the optical transmittance is >90%, while the optical energy gap increased with increase of Al doping ratio.
