The importance of research and the need for him

We have recently increased prevalence of behavioral problems rate, especially among young people, and this has become clear to all. In the light of social changes, political and economic and security conditions and technological advances enormous, especially in the means of communication such as the Internet and satellite television and mobile phone, resulted in the entry of some habits and Western values on our society which led to a vibration private values with low economic situation and the increasing youth unemployment and the resulting frustrations led to a situation of social chaos that we see now in th

También, intentamos arrojar luz sobre muchas preguntas sobre elarte de investigar, las cuales seguramente admiten varias respuestas y opiniones,pero que creemos pueden ser todas igual de válidas.

In this paper, Response Surface Method (RSM) is utilized to carry out an investigation of the impact of input parameters: electrode type (E.T.) [Gr, Cu and CuW], pulse duration of current (I_p), pulse duration on time (T_on), and pulse duration off time (T_off) on the surface finish in EDM operation. To approximate and concentrate the suggested second- order regression model is generally accepted for Surface Roughness Ra, a Central Composite Design (CCD) is utilized for evaluating the model constant coefficients of the input parameters on Surface Roughness (Ra). Examinations were performed on AISI D2 tool steel. The important coefficients are gotten by achieving successfully an Analysis of V

Improving" Jackknife Instrumental Variable Estimation method" using A class of immun algorithm with practical application

Artificial Intelligence Algorithms have been used in recent years in many scientific fields. We suggest employing flower pollination algorithm in the environmental field to find the best estimate of the semi-parametric regression function with measurement errors in the explanatory variables and the dependent variable, where measurement errors appear frequently in fields such as chemistry, biological sciences, medicine, and epidemiological studies, rather than an exact measurement. We estimate the regression function of the semi-parametric model by estimating the parametric model and estimating the non-parametric model, the parametric model is estimated by using an instrumental variables method (Wald method, Bartlett’s method, and Durbin

Lorraine Hansberry’s A Raisin in the Sun (1959) appeared at the beginning of renewed political activity on the part of the blacks; it is a pamphlet about the dream of recognition of black people and the confusion of purposes and means to reach such recognition. It embodies ideas that have been uncommon on the Broadway stage in any period. Situations such as a black family moving into an all-white neighborhood were not familiar before this time; they were just beginning to emerge. In depicting this so realistically, Hansberry depends more on her personal experience as an African American embittered by social prejudices and discrimination. 

The research discusses the relations between Turkey and Japan, which began between the Ottoman Empire and the Meiji Empire in Japan since the arrival of Sultan Abdul Hamid II to power in 1976 and his interest in Japan as the first Asian country to achieve modernization. Both faced one problem during the late nineteenth century, which is the ambitions of Tsarist Russia and the suffering of the parties suffered unequal treaties. Relations between them have begun to develop slowly and gradually, especially after Japan received a large Ottoman delegation on board the Ertugrul frigate in 1890, through the First World War and the Treaty of Sevres, the arrival of Mustafa Kemal Ataturk to power and the establishment of the modern Republic of Turkey

      لاشك ان الاشكالية السياسية ومنها السلطة، اشكالية ابدية ما دام الانسان على وجه الارض يتحرك، والحضارة الاسلامية والعربية لم تكن ولن تكون مستثنى من هذه الاشكالية نظرا لطبيعة السلطة من جهة ولطبيعة الانسان الساعي دوما للسيطرة والحصول على المزيد من القوة وتحقيق الذات، لقد تناول الفلاسفة المسلمون  السياسة والامور التي تخص الدولة ونشاتها وكيفية ادارة الحكم الرشيد في الدولة منذ البواكير الاول

Exchange of information through the channels of communication can be unsafe. Communication media are not safe to send sensitive information so it is necessary to provide the protection of information from disclosure to unauthorized persons. This research presented the method to information security is done through information hiding into the cover image using a least significant bit (LSB) technique, where a text file is encrypted using a secret sharing scheme. Then, generating positions to hiding information in a random manner of cover image, which is difficult to predict hiding in the image-by-image analysis or statistical analyzes. Where it provides two levels of information security through encryption of a text file using the secret sha

Perimenopausal bleeding, is a very common problem, which is an alarming symptom for both; women and their doctors because of the rising fears of cellular changes or tumor of endometrium. In our study we tried to prove that collecting endometrial samples using the outpatient method of Pipelle is as effective as collecting the endometrial samples in the traditional method of Dilation and Curettage (DandC) in operation theatre which necessitates general anesthesia. Ninety four patients more than 40 years old were included in the study, all of them were complaining of abnormal uterine bleeding (pregnant ladies and ladies using hormonal contraception were excluded from the study) and endometrial samples were collected first in outpatient

Synthesis and study liquid crystalline properties of novel Benzimidazol-8-hydroxyquinoline complexes by reaction of a-Chloro acetic acid with 3,3'-dimethylbiphenyl-4,4'-diamine in 10% aqueous sodium hydroxide to synthesized compound [I] then the later compound reacted with o-phenylenediamine in 4N Hydrochloric acid to synthesized compound N4,N4'-bis((1H-benzo[d]imidazol-2-yl)methyl)-3,3'-dimethyl-[1,1'-biphenyl]-4,4'-diamine =[II] . While the complexes [III],[IV],[V],[VI] and [VII] synthesized from reacted compound [II] , 8-hydroxyquinoline with metal(II) salts { M= Mn(II), Fe(II), Ni (II), Cu(II),and Zn(II)}. Newly synthesized compounds were characterized using melting points, FT-IR, UV-Vis spectra, and some of them 1H NMR spectroscopy. ma

A new pavement technology has been developed in Highway engineering: asphalt pavement production is less susceptible to oxidation and the consequent damages. The warm mix asphalt (WMA) is produced at a temperature of about (10-40) ^oC lower than the hot asphalt paving. This is done using one of the methods of producing a WMA. Although WMA's performance is rather good, according to previous studies, as it is less susceptible to oxidation, it is possible to modify some of its properties using different materials, including polymers. Waste tires of vehicles are one of the types of polymers because of their flexible properties. The production of HMA, WMA, and WMA modified with proportions of (1, 1.5, and 2%) of rub

The aim of this study is to provide an overview of various models to study drug diffusion for a sustained period into and within the human body. Emphasized the mathematical compartment models using fractional derivative (Caputo model) approach to investigate the change in sustained drug concentration in different compartments of the human body system through the oral route or the intravenous route. Law of mass action, first-order kinetics, and Fick's perfusion principle were used to develop mathematical compartment models representing sustained drug diffusion throughout the human body. To adequately predict the sustained drug diffusion into various compartments of the human body, consider fractional derivative (Caputo model) to investiga

Background: The aim was to ascertain the current practice of adjuvant therapy for tonsillectomy and to determine whether it is evidence based.
Methods: A questionnaire answers were obtained from sixty otolaryngologists in Baghdad.
Results: There was no any enthusiasm for routine intra-operative local anaesthesia. Paracetamol (Acetaminophen) is prescribed by nearly all surgeons for postoperative analgesia,
and the current literature supports its efficacy and safety. Further, some practitioners combine paracetamol with NSAIDs, and/or Tramadol-Opioids. Evidence to support the additional use of these agents is, however non existent or limited. For the use of antibiotics, we found some of the otolaryngologist
