The recent development in statistics has made statistical distributions the focus of researchers in the process of compensating for some distribution parameters with fixed values and obtaining a new distribution, in this study, the distribution of Kumaraswamy was studied from the constant distributions of the two parameters. The characteristics of the distribution were discussed through the presentation of the probability density function (p.d.f), the cumulative distribution function (c.d.f.), the ratio of r, the reliability function and the hazard function. The parameters of the Kumaraswamy distribution were estimated using MLE, ME, LSEE by using the simulation method for different sampling sizes and using preli

Show MoreThis research of using Feldspar in the production self compacting concrete (SCC) ( 5,10,15 )% as partial replacement by weight of cement .In this research some of fresh properties of SCC ( slump flow used V-funnel test and filling ability used ( U- box test ) for concrete mixes and also some of the harden properties of SCC ( compressive and flexural tests ). The research results showed that negative effect of Feldspar on the fresh properties of self compacting concrete but the positive effect of Feldspar on the harden properties of self compacting concrete .
The concept of civil society is one of the relatively recent concepts that have emerged clearly on the political and social arena especially in European countries, where it effectively contributes to the process of democratic transformation through the multiple roles and functions that it exercises, and acts as mediator between the state and the individual. Civil society in essence works to bring about change in society whether it is political, economic, social or cultural .The civil society appeared in Iraq after 2003, as is the case with many concepts that entered Iraq and took upon themselves the building of a democratic Iraq .Accordingly civil society institutions are the entity capable of rebuilding the Iraqi personal
... Show MoreThis paper attempted to study the effect of cutting parameters (spindle speed and feed rate) on delamination phenomena during the drilling glass-polyester composites. Drilling process was done by CNC machine with 10 mm diameter of high-speed steel (HSS) drill bit. Taguchi technique with L16 orthogonal layout was used to analyze the effective parameters on delamination factor. The optimal experiment was no. 13 with spindle speed 1273 rpm and feed 0.05 mm/rev with minimum delamination factor 1.28. &

Show MoreThe research aims to demonstrate the role of organizational justice as an independent variable in influencing the achievement of development of the sense of psychological ownership of workers as a dependent variable. The current research variables were distinguished as being effective variables in terms of the field and affecting the achievement of success for organizations. In order to achieve this goal, it was applied on a sample of employees in the Iraqi Ministry of Transport employees, whose number reached (84) individuals, and the data were collected through the questionnaire as a main tool, to come out with a set of conclusions that contribute to raising the levels of the researched company, and based on the importance of the
... Show MoreThe structural properties of ternary chalcopyrite AgAlSe2 compound alloys and thin films that prepared by the thermal evaporation method at room temperature on glass substrate with a deposition rate (5±0.1) nm s-1 for different values of thickness (250,500 and 750±20) nm, have been studied, using X-ray diffraction technology. As well as, the optical properties of the prepared films have been investigated. The structural investigated shows that the alloy has polycrystalline structure of tetragonal type with preferential orientation (112), while the films have amorphous structure. Optical measurement shows that AgAlSe2 films have high absorption in the range of wavelength (350-700 nm). The optical energy gap for allowed direct transition we

Background: Ulcerative colitis is a chronic inflammatory condition characterized by relapsing and remitting episodes of inflammation limited to the mucosal layer of the colon.Loop ileostomy might be helpful in the management of the disease.
Objective: To evaluate the role of loop ileostomy in the management of ulcerative colitis.
Methods: Between Januarys 2008 and January 2018, patients with fulminant ulcerative colitis resistant to medical therapy had been referred to our surgical unit and were included in our study. Assessment of the patients’ medical status (serum electrolytes, total serum protein, complete blood count, erythrocyte sedimentation rate, general stool exam,and abdominal ultrasound
... Show MoreThis study aims to explain the purposes of thinking in light of the Holy Qur’an. The study adopted the deductive method by analyzing the meanings of the eighteen thinking verses mentioned in the Holy Qur’an That is by referring to the ancient and contemporary book interpretations and inferring the purposes of thinking from the context of those verses. The study concluded that there are seven main purposes, for thinking in the light of the Holy Qur’an, are understanding the universal regulations, contemplating the social codes, inferring, extracting maxims and meanings from the Qur’anic proverbs, analyzing the situation objectively, balancing between interests and evils, and freeing the mind from the authority of the paranormal.

... Show MoreIn the last decades of the twentieth century, ideas emerged that were increasingly being floated, stating that the planet is suffering from a population explosion, depletion of resources, and environmental problems that require action to be addressed. Although these problems in practice need scientific solutions, the problem is that these solutions collide with ideologies. Here the green political thought emerges, based on the criticism of many ideological axioms. The owners of green thinking agree that most environmental damage is due to the humanist doctrine. It criticizes modernity accompanied by a scientific revolution, where this criticism centered around (the rationality of the scientific and technological mind), here the green pol
