Abstract: Introduction: The aim of this study was to compare the behavioral disorders among children between the age of 7-12 who live in public or private care centers in Tehran.Material and Methods: The research method of causal-comparative and population of derelict and children 7-12 years institutionalized Tehran. Sampling was done and the way unit 128 children residing in public and private institutionalized were eligible to enter the study through behavioral assessment Rutter Scale (parents and teachers) were evaluated. A demographic list was also used. To analyze data collected, frequency table and U-Mann Whitney were conducted.Results: Results showed that abnormal behavior, social maladaptation, and the attention deficit disorder were significantly more in public than private centers. In antisocial behavior and hyperactivity-aggression no significant difference were observed. Anxiety and depression in governmental centers children is significantly higher than nongovernment centers. Children with poorly functioning families who were being held in both kind of facilities showed more behavioral disorders than orphan children.Discussion: It appears that private child care centers have been successful in working with orphaned children or those with uncaring parents. Skilled manpower and adequate distribution of resources among children (due to low numbers in each center) are considered to be part of the reason for this success.

Abstract: This research was carrying out with purpose of investigation about teachers’ and managers’ view about annual evaluation system of teachers’ performance. The research method was descriptive (survey research) and statistical population included all elementary teachers and managers in Malayer. The total numbers of teachers were 3050 and mangers were 301. For sampling, a biased method was used. So, 170 managers and 380 teachers were selected. The instrument was two research-made questionnaires. For validating of questionnaires, the content and formal validity was used. So, the specialists’ appraisal was applied. Also for making questionnaire reliable the Coronach’s alpha was used. So, alpha coefficient for managers’ and teachers’ questionnaire respectively was: 0.96 and 0.87. However, the result shows that from manager’s view the annual evaluation system of teachers’ performance is appropriate, but that from teachers’ view it isn’t good. Also another result shows that, there are significant differences between teachers’ and managers’ view about quality of annual evaluation system of teachers’ performance, in totally and in all domains (instructional domain, discipline domain, good humanity relationship, cooperation of teachers, scientific researches of teachers, and job motivation of teachers).
Red cell antigens: Structure and function
Pourazar Abbasali
Asian Journal of Transfusion Science , 2007,
Abstract: Landsteiner and his colleagues demonstrated that human beings could be classified into four groups depending on the presence of one (A) or another (B) or both (AB) or none (O) of the antigens on their red cells. The number of the blood group antigens up to 1984 was 410. In the next 20 years, there were 16 systems with 144 antigens and quite a collection of antigens waiting to be assigned to systems, pending the discovery of new information about their relationship to the established systems. The importance of most blood group antigens had been recognized by immunological complications of blood transfusion or pregnancies; their molecular structure and function however remained undefined for many decades. Recent advances in molecular genetics and cellular biochemistry resulted in an abundance of new information in this field of research. In this review, we try to give some examples of advances made in the field of ′structure and function of the red cell surface molecules.′

Extremal basic frequency of non-homogeneous plates
Abbasali Mohammadi
Mathematics , 2013,
Abstract: In this paper we propose two numerical algorithms to derive the extremal principal eigenvalue of the bi-Laplacian operator under Navier boundary conditions or Dirichlet boundary conditions. Consider a non-homogeneous hinged or clamped plate $\Omega$, the algorithms converge to the density functions on $\Omega$ which they yield the maximum or minimum basic frequency of the plate.
Optimal ground state energy of two-phase conductors
Abbasali Mohammadi,Mohsen Yousefnezhad
Mathematics , 2014,
Abstract: Consider the problem of distributing two conducting materials in a ball with fixed proportion in order to minimize the first eigenvalue of a Dirichlet operator. It was conjectured that the optimal distribution consists of putting the material with the highest conductivity in a ball around the center. In this paper, we show that the conjecture is not true for all dimensions $n \geq 2$.
A nonlinear eigenvalue problem arising in a nanostructured quantum dot
Abbasali Mohammadi,Fariba Bahrami
Mathematics , 2014, DOI: 10.1016/j.cnsns.2013.11.017
Abstract: In this paper we investigate a minimization problem related to the principal eigenvalue of the $s$-wave Schr\"{o}dinger operator. The operator depends nonlinearly on the eigenparameter. We prove the existence of a solution for the optimization problem and the uniqueness will be addressed when the domain is a ball. The optimized solution can be applied to design new electronic and photonic devices based on the quantum dots.
Faith & Reason: A Synthesis in Pakistani Society
Naveed Yazdani
Pakistan Journal of Commerce and Social Sciences , 2009,
Abstract: The basic objectives of this paper are to build a general level of understanding towards the need for synthesizing and harmonizing religious, scientific and philosophical thoughts as they are developed and practiced in Pakistan or in other words, bringing the Islamic and western incliners close to each other and also in outlining some practical methodological ways through which this process of integration can be put on track leading towards a forward looking and modern Pakistani society while retaining its core and basic fabric of faith and religion. The paper has three sections, the first section highlights the needs and reasons for synthesis in relation to various segments of our society and also point out the potential adverse consequences of not undertaking and building an integrative view. The second section suggests some ways, measures and methods of achieving the above mentioned thought of integration across the society and focuses on some of the collective and institutional level endeavors and commitments required to actualize this integration. The third section of this paper issues some warnings regarding the process of integration and its possible undesirable repercussions on the society, in light of some of the earlier such attempts. The research draws some practical steps which need to be undertaken in the Pakistani society for creating a synthesis between Faith and Reason.
Celiac Disease as a Potential Cause of Idiopathic Portal Hypertension: A Case Report
S Yazdani
Qom University of Medical Sciences Journal , 2012,
Abstract: Background and Objectives: Celiac disease can be associated with various extra intestinal symptoms such as primary biliary cirrhosis and auto immune hepatitis but idiopathic portal hypertension is a very rare phenamenon. IPH patient typically has splenomegally, esophageal varices and sometimes Icter and ascitis. Case Report: A case of IPH in a 38 year old woman with celiac disease. She had been suffering from Ascites, Splenomegally, malaise and apathy for several years and had undergone treatment for cryptogenic cirrhosis. Diagnostic re-examination of the patient such as Serology tests and markers from Wilson disease, auto immune and viral hepatitis showed negative reports, but her liver function test and ESR were prolonged In upper GI endoscopy esophageal varices was detected. Abdominal sonography reported moderate to severe splenomegally and rise of portal vein diameter but did not show any evidence of thrombosis. Liver biopsy revealed no sign of cirrhosis. But duodenal biopsy and serologic finding were compatible with celiac disease. Her symptoms improved on a gluten-free diet and her liver function test and ESR were normal.
An in vitro Study on the Adsorption, Absorption and Uptake Capacity of Zn by the Bioremediator Trichoderma atroviride

Abstract: The concentrations of Zn in the sediment of a polluted river at the Serdang Industrial Area were determined. These polluted sediment samples revealed high level of Zn (219. 27 μg/g). Isolation of fungi from this polluted sediment was also carried out using Rose Bengal Agar (RBA). The isolated fungi were exposed to different concentrations of Zn (0-6000 mg/L) on Potato Dextrose Agar (PDA) to find the most tolerant isolate. Trichoderma atroviride was found to have the highest tolerance and it was studied for growth rate, Zn uptake capacity, its tolerance to Zn and also localization of Zn by using Potato Dextrose Broth (PDB) as the liquid culture medium. In the present study the results found out that the uptake capacity of T. atroviride ranged from 18.1-26.7 mg/g in liquid media at Zn concentrations from 500 to 1000 mg/L. The isolate showed 47.6-64% adsorption and 30.4 45.1% absorption for Zn. Based on the present study, 5.7-7.4% of Zn removal was observed due to biomass washing. The high adsorption, relatively low absorption and high uptake capacity of Zn suggest that T. atroviride is a potential bioremediator of Zn. However, further studies are needed to confirm its practical use as a bioremediating agent for Zn under field conditions.
