In the current study, a mathematical model using the MATLAB program was studied depending on the logistic power peak function to simulate the change in the absorbance with the different values of the concentrations of Rhodamine B. There are five parameters that have been applied to the concentration values of this laser dye that are proposed by the logistic power peak function of the seventh degree. To measure the absorption measurements, a range of concentrations from 4.7x10-7 to 3.76x10-6 M was prepared from Rhodamine B and dissolved in deionized water with a peak absorption at 556 nm. A JASCO V-630 spectrophotometer was used to record the spectra of the dye. The intensity is detected using a silicon photodiode (S1337). The results were found that the suggested function approved the relationship between the absorbance and the values of the concentrations with a significant accuracy depending on the high values of the correlation coefficients between the approximated original data which were determined more than 99.2%. The advantages of this function represent by providing parameters, which are used to describe the mathematical processes with high-resolution property profiles.

Abstract: The experiment has been conducted at the poultry farm of Al-Qadisyah University, College of Agriculture, Department of Animal Production , for the period 24/11/2018 till 10/4/2019 by using 80 hatching chicks which belong to 20 dams and 5 sires, each sire includes 16 chicks. Four chickens are put with each sire, the first sire( Leghorn) crossbreeding with dams of Lohmann , the remaining sires are local cocks ,with five Lohmann hens. The chicks of each sire divided into two replicates ,each replicate contains 8 chicks , the experiment continues for 42 days of age. The experiment aims to study the effect of sire groups on growth traits (weight at hatching , weight at 42 days of age , weight gain and daily weight gain ) Also , the effect of sire on weekly consumption feed , in addition to estimate the heritability for previous traits and the genetic correlations among these traits. The results can be summarized as follows : 1- The overall means of weight at hatching , weigh at 42 days of age , weight gain and daily weight gain are 34.572 , 354.898 , 320.327 and 7.627 gm respectively , the sire groups appear significantly (p0.05) effect on weight at hatching and weight at 42 days of age and weekly consumption seeds. 2- Sex has significantly (p0.05) effect on weight at hatching and weight at 42 days of age. 3- The conversion feed ratio is 3.462 gm consume feed/ gm of meat. 4- The estimated values of heritability for weight at hatching weight at 42 days of age , weight gain and daily weight gain and daily weight gain , are 0.332 , 0.55 , 0.55 and 0.56 respectively. The values of genetic correlation between weight at hatching and weight at 42 days of age and between weight at hatching and weight gain are 0.98 and 0.58 respectively.

From the time being, there are even instances for application of mobile robots in our life like in home, schools, hospitals, etc. The goal of this paper is to plan a path and minimizing the path lengths with obstacles avoidance for a mobile robot in static environment. In this work we depict the issue of off-line wheeled mobile robot (WMR) path planning, which best route for wheeled mobile robot from a start point to a target at a plane environment represented by 2-D work space. A modified optimization technique to solve the problem of path planning problem using particle swarm optimization (PSO) method is given. PSO is a swarm intelligence based stochastic optimization technique which imitate the social behavior of fish schooling or bird flocking, was applied to locate the optimum route for mobile robot so as to reach a target. Simulation results, which executed using MATLAB 2014 programming language, confirmed that the suggested algorithm outperforms the standard version of PSO algorithm with the same environment conditions by providing the shortest path for mobile robot.

Chemical composition of the essential oil extracted by hydrodistillation (Clevenger apparatus) from some aerial parts (ripe and unripe fruit) of Pistacia Atlantica (Anacardiaceae) which are widely spread throughout the countries of the Mediterranean Sea and have been occupying a good part of the mount of Syria was determined by Gas Chromatography-Mass Spectrometer GC/MS. The results of analyzing showed that the oil consist of five compounds in ripe and unripe fruit, and it was found that the component with the highest ratio in both samples is the same 2-methylbutanal and its ratio 95.713% in the ripe fruit and 94.138% in the unripe fruit. The results of this study also show that the essential oil components of the Syrian Pistacia fruits are completely different from those in different environments due to the different types of pistacia species which have been studied and the different environmental conditions in which this plant grows.

This study aims to identify how Arab press deals with issues of tolerance and ways of addressing the Other. The study traces this theme in some of the major Arab daily newspapers inside and outside the Arab world. These newspapers are: Al-Ahram, Al- Riyadh, Al-Sharq Al-Awsat, and Al-Hayat. The study argues that the media alone do not create the image or even attempt to change it. In fact, there are other institutions that strive to do this. In all societies, there are institutions that actually provide the raw material which is then used to form the desired stereotypical image of individuals, societies, countries, and institutions. The media then seize this material, forge it and integrate it with framed media packages that are then used as ready-made recipes to produce, alter or reinforce these stereotypes in which the Other is always an embedded element. The study recommends that Arab media need to develop awareness among Arab citizens through enhancing positive principles and values that contribute to the social cohesion of the society. They also need to stress the issue of identity and encourage an active role of individuals in issues of common social interest. They need to promote a culture of acceptance of the Other, however different that Other might be.

The present study deals with the effect of parents- teachers conferences on the achievement of third Intermediate class . It has been noticed that some students' parents do not get involved in school activities or support school goals at home .and that will affect on the students' progress .

The books of travels that Muslim travelers undertook in different places; The descriptions of women focus on her physical image and places of temptation and beauty, which means that travelers have reflected different aspects of women's social, psychological, religious and moral natures, and these aspects were multiplied by the multiplicity of the image of women, so their views varied greatly through the multiplicity of sites and different countries, and whether the woman was a girl, sister or A wife, her image has changed with the different nature of these regions and the change of their cultures from one environment to another. From the sources of travel literature, whose beginnings we did not specify, because we followed the images of women in those books, some of which refrained from mentioning women, so we dealt with these texts from various travel sources, content with research until the end of the eighth century AH / fourteenth century AD, and although the features of authorship in travel literature Its features became clear during the fourth century AH / tenth century AD, which appeared at the hands of a number of Muslim travelers and contributed to the formation of the literary discourse in this type of ultra storytelling. We also set a historical beginning for the investigation of the research, because the trips began to flourish during the fourth century AH due to the flourishing of the civilizational aspects at that time and the cultural mixing between nations and peoples. We divided the research into an introduction and a summary in English, two chapters and a conclusion, then a list of margins, followed by a list of approved sources and references [ABSTRACT FROM AUTHOR]
