The structure of assimilating organs in five species of Сlimасорtеrа is described: mesophylls of cotyledon, leaf, bract and perianth. The change type mesophylls assimilating organs from the cotyledons (and leaf bracts, bracteoles) to perianth in species Climacoptera on saline soil and Mirzachul (Uzbekistan, Province Sirdarya) and Kyzylkums (Uzbekistan, Province Buhora, Navoiy, Karakalpakstan, Province Miskin) related C3 and C4 types of photosynthesis. Identified quantitative parameters Kranz-cells and their variability in the ontogeny of plants and species specificity. The level of their specialization, xeromorphy and halomorphy is determined. Regularities of adaptation of succulent species with the Kranz anatomy to xero- and halo factors, which enable insights into the nature of their halophytism, are revealed. A high coefficient of the similarity of species from one section in different habitation conditions was shown using the cluster analysis.

Flexibility played an important role in enabling managers to invest in the future plays. The purpose of this study was to evaluate the impact of the financial flexibility of companies listed on the stock exchange is capital structure decisions. The Survey of aim, an applied research.

Finally, with regard to the limitations of the study, data were collected on 125 companies and Then, using a Cochran formula 94 companies with a convenient random sampling (samples available) were selected.. Document the results for statistical analysis and provide the final solution, the researchers statistical methods using SPSS software has attempted to analyze the questions and hypotheses. Two hypotheses using multiple linear regression and multivariate F and t tests were analyzed. Hypothesis test results show that: All variables marginal value of cash, the value of flexibility and leverage ratios, capital structure decisions have direct and significant relationship.

The aim of this research is Effect of School in preventing of crimes committed by children and adolescents. The book about the role of the school and its agents on the prevention of crime, children and teenagers every year, with the reopening of schools discussions about the quality of education, training, schools and its likes, but the attention of public opinion, experts in this field and officials to other tasks and education that is farmed later.

Schools as a task that the education of children and teenagers in the hours of the night and day is the most important are that can prevent social damage. prevention of students to the crime, especially after the stages of education and reach a large, something that is in proportion to their age and gender, should be the executive plan and Management style in schools, the most important factor in achieving the effectiveness and, therefore, when a combination of strong leadership decision-making in which all teachers feel that they have provided that the learning more desirable. for having a healthy society should be the role of educational institutions, deeming it is very important and the effects of that. Education is one of the most important and most influential institutions in improving the current training in society for the development and improvement of the pattern of life.

Identity and culture are two interrelated terms. Culture can shape the identity and make a fixed identity or hybrid one. This paper examines the formation of hybrid cultural identity of the male educated character, Obi Okonkwo, in Chinua Achebe's (1930-2013) No Longer at Ease (1960). The researchers make use of the issues of postcolonial arguments based on the theories of Homi K. Bhabha (1949- ) and Frantz Fanon (1925-1961). One of the consequences of confrontation between two different cultures during colonisation is transforming of identity, which results in hybridity of identity of the colonised people and culture. According to Bhabha, the space between different cultures, in which a hybrid identity is created, is third space. This third space depicts how colonialism and colonial power can transform the identity and make hybrid identities in Nigeria. By considering the situation of a hybrid character like Obi and British power, Achebe tries to focus on the problems of identification among Nigerians. Obi's life and identity have been formed based on the effects of colonialism. Fanon usually puts emphasis on the role of education and literature in the reviving of self-respect of Africans. For Fanon, 'inferiority complex' caused by colonial education, invites the black man to follow white man's values and forget his own culture. This process results in the rejection of native values by the black people. No Longer at Ease provides a picture of beauties and complexities of Nigerian culture. Achebe shows that religion and rituals are two important factors in keeping the native culture, identity and social norms of Nigeria alive. Illustrating the old tradition of Nigeria, he tries to reject the colonial thinking about Africa as a land without history and civilisation.

Background: Neurofibromatosis is an autosomal dominant disorder, which means only one copy of the affected gene is needed for the disorder to develop. If only one parent has neurofibromatosis, his or her children have a 50% chance of developing the condition as well. The affected child could have mild NF1 even though inherited from a parent with a severe form of the disorder. Cases: Reviewing 2 cases of a family that mother and his sister previously diagnosed. Each son assessment by radiological intervention such as MRI, of course history and clinical assessment at that time be taken. In this report, we were finding ectopic Neurohypophsis in one of the son that it was rare finding in this disease. Also, in this article we review of literature and references.

Adenosarcoma is a biphasic tumor with benign epithelial elements and a sarcomatous stroma. Typically it presents as a solitary large polypoid mass arising from the uterine fundus. In this case report we presented a 64 year-old woman with postmenopausal bleeding and endometrial polypoid lesion in sonographic report. Pathologic examination of the curetting specimen revealed a mixed epithelial-mesenchymal tumor that it was diagnosed as adenosarcoma.

Human being has long been considered by management experts in the organization and management world.

The change is fast, complex and unpredictable and is a significant impact on organizations and their leadership style. Managers should be competent leaders to transform his people and organizations to obtain the necessary returns. A leader because of the wide variety of workplaces have different roles to play in order to enable them to cope with the changes to abilities such as group-oriented, strong communication, solving problems, creating changes need to leader.

The purpose of this study was to compare the effectiveness of Map concept teaching with traditional teaching methods on academic achievement, material durability and misunderstanding reduction of science between fifth grade students of Zahedan. The quasi-experimental method is used in this study. Four classes were chosen for the study, two classes as control group (one is guy class and the other is a girl class) and two classes as an experimental group (one is guy class and the other is a girl class) and a pre-test applied to equal experimental and control group. Teaching was done with the traditional and wide methods over 20 sessions of classes in two groups, with the approach of the conceptual map and two classes in control groups. Finally, achievement test scores, retention issues test and misunderstanding test of both groups were compared and were analyzed by using analysis of variance and mix analysis of variance between and inside groups. The results showed that teaching by conceptual map approach is more effective on raising achievement and sustainability issues, as well as reducing misunderstandings of students compared with conventional and common method. In addition results indicate that there is a significant difference between girls and boys in terms of academic achievement, and the impact of a concept map approach on academic achievements of girls is more than boys, but there is no significant difference between male and female groups in the durability of the issues and reducing misunderstandings.
