In these complexes, metal ion assisted the assembly of the complex formation. ligands were prepared from the reaction of precursors with CS2, Preparation of the precursors was based on using of secondary diamines, which were synthesised in two steps; first step includes preparation of acetamide precursors from the reaction of benzidine with chloroacetyl chloride or dichloroacetyl chloride in the presence of alkali base (KOH), while second step based on preparation of secondary amines from the reaction of acetamide with primary amines.The ligands were prepared from the reaction of carbon disulfide and secondary amines in the presence of alkali base (KOH) that gave the free ligands (L1, L2, L3, L4).Where : L1= (potassium 2,2' - (biphenyl - 4,4' - diylbis(azanediyl))bis(2 - oxoethane - 2,1 - diyl)bis(propylcarbamodithioate)L2=(potassium2,2' - (biphenyl - 4,4' - diylbis(azanediyl))bis(2 - oxoethane - 2,1 - diyl) bis(benzylcarbamodithioate)L3= (potassium2,2' - (biphenyl - 4,4' - diylbis(azanediyl))bis(1 - chloro - 2 - oxoethane - 2,1 - diyl)bis(cyclohexylcarbamodithioate)) L4=(potassium2,2' - (biphenyl - 4,4' - diylbis(azanediyl))bis(2 - oxoethane - 2,1 - diyl) bis(isopropylcarbamodithioate)) The aim of preparation of the free ligands was to allow us conducting full characterisation on the ligands. The free dithiocarbamate ligands; L1 , L2, L3 and L4 (see Scheme). Scheme : Synthetic route for ligands L1 , L2, L3 and L4 The bimetallic complexes were synthesised using two approaches; (i) from the reaction of free ligand with metal ion, and (ii) via a one pot reaction. In free ligand approach; complexes were prepared from the reaction of equivalent potassium dithiocarbamate salt with equivalent of the metal salt; MnII, CoII, NiII, CuII, ZnII and CdII. In the second approach; the complexes were prepared in one pot reaction by mixing carbon disulfide, with the appropriate secondary amine and metal salt in the presence of (KOH) using mixture of MeCN : H2O. Ligands and complexes were fully characterised by elemental analysis for selected complexes, melting points, magnetic susceptibility for complexes, conductance, bacterial activity, FTIR, UV - Vis, mass spectroscopy L1 , L2, L3 and L4 and 1H - , 13C - , 13C - DEPT at 135º and COSY NMR spectroscopy. FTIR and NMR studies revealed a bidentate coordination mode of the CS2 moiety to the central metal ion. Furthermore, FTIR studies showed asymmetric (anisobidentate) and symmetric bidentate coordination mode. Physico - chemical analysis revealed that the bisthiocarbamate macrocyclic complexes exhibited four coordinate structures in the solid and solution state with the general formula : [M(Ln)]2 (where M = Mn II, CoII, NiII, CuII, ZnII and CdII; Ln = L1 - L4)

The swelling ratio was measured for all the hydrogel samples at 37°C, in three different media pH (1.2,4.7 and 6.8) as a function of time, the samples involving the highest swelling ratio were arranged as follows : PVA / PAA (5% ) > PVA / GA (5% ) It was observed that the swelling degree cross linked PVA hydrogels depend on pH on of buffer solution . The effect of pH on swelling ratio was also studied for all the hydrogel structures , the results show that the maximum swelling ratio was arranged as follows : pH =6.8 > pH =4.7 > pH =1.2 hydrogels cross linked PVA showed a typical pH responsive behavior such as high pH has maximum swelling while low pH shows minimum swelling. The drug Ketotifen hydrogen fumarate was mixed with polymer solutions crosslinking agent and mixture was added to the polymerization medium .The concentration of ( KET) released was measured by UV spectrophotometer. A calibration curve between absorbance and concentration was constructed to show the linearity by using serial dilution method from stock solution of pure drug .The concentration of release was calculated by extrapolation of the result on the calibration curve every 10 min . The detection limit for (KET) was minimum used (5 - 55) mg.L - 1 wave length at 300 nm . The drug release from the (KET) loaded hydrogel was studied in three different medias pH (1.2 ,4.7 and 6.8) at 37°C as a function of time .The results show that the samples involving the highest release of drug were arranged as follows : PVA / PAA (5%) > PVA / GA (5%) . The effect of pH on release of drug was also studied for all samples. The result shows the maximum release of drug was arranged as follows pH =(6.8)> pH =4.7 > pH =(1.2)

The optimum reaction conditions and other analytical parameters were evaluated. The results showed better optical characteristics for calibration curve and statistical data were obtained under optimum conditions using direct Spectrophotometric determination of micro amounts of copper ion. “Beer's law” is obeyed in the concentration range (0.1 - 10)g.mL - 1 , having molar absorptivity of 5842L. mol - 1. cm - 1. The value of detection limit was 0.0238g.mL - 1 . Interference study indicated that some metal ions like Ni+2, Cr+3 have exceeded the allowable limits of interference for copper ion absorbance signal. The proposed method was applied successfully for the determination of copper ion in various water samples.Part Two : Deals with the formation of a hydrophobic complex between copper ion and methionine in rich - surfactant phase, by “cloud point extraction” (CPE) methodology, coupled with UV - Visible spectrophotometry. This method involved reaction of copper ion with methionine as a chelating agent to form a hydrophobic complex. Which was extracted at specific pH by CPE technique using nonionic surfactant Triton X - 100.as an extraction medium. The complex was surrounded by surfactant micelles. The surfactant - rich phase was diluted with methanol and the complex was measured spectrophotometrically at it's (max= 294nm). Different factors that can influence the extraction efficiency of copper ion has been optimized by using one - factor - at - a - time (OFAT). These factors include solution pH, reagent and surfactant concentrations, temperature and incubation time. Besides the interference effect of cations was also considered under the optimized conditions, “preconcentration factor” of 90 was achieved. The linear range was (0.1 - 4)g.mL - 1 with “limit of detection” and limit of quantification (0.0071), (0.0215)g.mL - 1 respectively and molar absorptivity of (19621.5) L. mol - 1. cm - 1.The Stoichiometric study was determined by “mole ratio method and continuous variation method” (Job's) at specific pH. The results showed that the Stoichiometric ratio between copper ion and methionine was 1 : 2.The proposed method is compared with the direct spectrophotometry determination of copper ion and the results have shown that there is a significant differences in accuracy and precision between the two methods and the cloud point extraction which indicates that the latter is more accurate and more precise. The suggested method was applied successfully for the determination of copper ion in water samples

المستخلص: The contemporary world is characterized by change and instability due to the successive developments and challenges in all the fields and in all levels, whether local, regional and global. This is why decision makers are required to search in order to identify the changes and the challenges, which the institutions and the organization may face in all sectors in order to improve them and also to cope with the developments in order to deal with them positively, through the use of the contemporary concepts in administration. The reason behind this is to find new active systems which enhance the activity of the organization to achieve uniqueness.The development in administration is the real scale for the development in different aspects of life, and also the first step for the comprehensive development. It focuses on augmenting the efficiency of human beings and putting the organizational structures through organization, assigning the duties which are considered to be the basic activities for the administrative development. This should be done in a way that guarantees doing the duties in a more active way. The new trends in administrative development also focus on effecting changes in the behavioral and intellectual activities in the administrative system.They depend also on the integrative and comprehensive view for their elements in order to enable the organizations to adjust to the environmental changes through creating variables for the inputs and activities, in a way that leads to the increase of the abilities to create a healthy milieu and improve its abilities to solve the problems and achieve self - improvement in order to face the environmental demands. Universities are considered the major centers which make the changes and developments, because they have the premises of creativity and innovation, through their academic and administrative qualities, and also through their rare specialization working there. Universities are also considered the intellectual, academic and civilization center in their societies. So, their roles in human and economic development go beyond the university walls to serve the society and interact with the other societies through the process of education, production and the other services.The influence of the university in the society is determined by the roles which it does in activating the self - potentials of the society, to eradicate illiteracy, achieve total development, redeeming the gap between the society and the leading societies. This will not be achieve if the university is confined inside its walls, to lay ties with the society. It must expand its duties and roles to support the efforts of economic and social growth.The following are some of the important conclusions : 1 - The weakness of the university in making use of its qualities in a way that best reflects their fields. Many specialists are assigned to work in a work that is not their field of specialization and there is also no accurate job description for many of them.2 - The organizational Structure needs the management engineering which makes it more flexible and more diverse in a way that best suits the contemporary trends and advancements.

المستخلص: هدف البحث الحالي الى : - تحليل محتوى كتب الكيمياء للمرحلة المتوسطة على وفق قضايا العلم والتكنولوجيا والمجتمع والبيئة ( S.T.S.E ). ولتحقيق هدف البحث صيغ السؤالان الاتيان : - 1 - ما قضايا العلم والتكنولوجيا والمجتمع والبيئة ( S.T.S.E ) المتضمنة في محتوى كتب ا | The aim of the present research is to : Analysis of chemistry books for the intermediate stage and according to science and technology, society and environment issues ( S.T.S.E ). To achieve the aim of the research the following two questions formats : - 1 - What are the Science and technology, society and enviermental issues (S.T.S.E) which included in the content of the chemistry books for the preparatory stage?2 - What are the Science and technology, society and enviermental issues (S.T.S.E) which supposed to be included in the content of the chemistry books for the preparatory stage?And to answer the research questions : Related to the first question : - The researcher has depended on previous studies in the field of (S.T.S.E), movement and projects that has contributed to reform of the science curriculum in order to prepare a list of science and technology, society and enviermental issues (S.T.S.E) , the first draft of the issues list consisting of (9) main issues and (69)sub - issues emerged. The researcher distributed the first draft of the list among experts in teaching chemistry, curricula and teaching methods, teachers and supervisors who were expert in the area of teaching chemistry methodsthen the researcher gave them enough time to check each item and removing or adding what is suitable for the tool to become in its final draft which included (9) main issues they are (Air quality and the atmosphere, sustainable development, water security, health and preventive security, mineral resources investment, pollution of various kinds, energy, food industry, production of weapons technology) and from which (70) sub - issues emerge. Then, the researcher analyzed the content of the chemistry books for the preparatory stage in the academic year (2015 - 2016) depending on the prepared list of the (S.T.S.E), the researcher depended the unit analysis, both (implicit and explicit) and repetition unit of the Census, the stability of the analysis was counted with the agreement of an outlaws analysts and the researcher himself.The researcher used Holisti equation for calculating reliability coefficients values, the results showed by using frequencies and percentages : - 1 - The chemistry books for the preparatory stage achieved ( 35) sub - issues with percentage of (50 % ), and this percentage is not good if we compare it with the criterion percentage that was adopted by the researcher depending on the experts opinions which was ,(70%).2 - Principles of Chemistry book for the first level preparatory class is the most book that gave an attention to the (S.T.S.E) issues with percentage of (65%), and (156) recurrence, but the second preparatory class was the least book that gave an attention to the (S.T.S.E) issues with percentage of (14,17%), and (34) recurrence.3 - health and preventive security issues settled at the first place with percentage of (27,08%), and (65) recurrence in the chemistry books for the preparatory stage, While the production of weapons technology issues settled on the last place and did not get any recurrence. 4 - The - sub - issue (the role of the chemical elements in nature) had the biggest number of recurrence which was (31), and settled at the first place, while many sub - issues did not get any repetitions.Respecting the second question : - The researcher found that most of the sub - issues were not included in the content of the chemistry books for the preparatory stage , which was included by the researcher within the issues list (S.T.S.E), The researcher finds that it is possible that the chemistry books for the preparatory stage should include the (S.T.S.E) issues in its content , Being a contemporary and important manner commensurate with the size of these issues, taking into account integration and relay and balance specially the main issues (mineral resources investment, food industry, production of weapons technology ) , which the current study had talked about it the knowledge of the researcher. Even though, the first issues took the third place, and the second issues was in the fourth place, but the third issue did not get any recurrence, which means the absence of balance and integration, related to the content of the chemistry books for the preparatory stage.In the light of the findings, the researcher came out with several recommendations, they are : - 1 - Including chemistry books for the preparatory stage with main and sub - main issues of the (S.T.S.E) issues that have not been included. 2 - Drawing the attention of specialists to reform science curriculum especially chemistry curricula, as one of the important modern attitudes in the scientific education.3 - Involving people who are interested in environmental education and specialists in the field of environment within special committees for plan science curriculum and specially chemistry curriculum. Complementing the current search the researcher suggested to conducting other studies to analyze chemistry books for the other stages, and other subjects such as physics in the light of the same issues.

There is no difference statistically significant at the 0.05 level between mean scores of teach physics laboratories at Baghdad University / College of Education Pure Sciences / Ibn al - Haytham who underwent the training program on the use of virtual laboratories and who did not undergo training on technological literacy scale.2. There is no difference statistically significant at the 0.05 level of significance between the average theoretical performance of the students who are studying the use of virtual labs and theoretical average performance scores for students who are studying by the traditional way according to grades.3. There is no difference statistically significant at the 0.05 level between the average operational performance of the students who are studying the use of virtual labs and hands - average performance scores for students who are studying by the traditional way according to grades. To achieve the objectives , the researcher conducted a field experiment took full academic year according to two phases : - first : Applying a Virtual Laboratory Training program on the first experimental group which is consisted of (16) male and female physics laboratory teachers. That was after constracting the training program needs' (identifying the training materials , formulating the behavioral objectives with determining their levels, identifying performance activities, preparing for the use of the virtual laboratory , and a directory for teaching aide and devices.) The control group consisted of (16) male and female physics laboratory teachers whom never been presented or trained by the program.Second : The second sample consisted of (54) second grade physics student , from faculty of education / Ibn al - Haytham college of education for pure sciences. This sample was divided into two groups. The experimental groups consisted of (25) male and female students were trained by the training program , the students were trained by the training program , the control group consisted of (29) male and female students was applied during the academic year (2014 - 2015) and lasted for two semesters (10 weeks) on aerate of one day per a week. After applying the experiment , the following results were obtained : 1 - The training program for virtual laboratories led to a positive change in the level of technological literacy to teach physics laboratories around the e - learning and virtual public laboratories in particular.2 - The effectiveness of the virtual laboratory program raised the theoretical level of performance for students in the second phase - the Department of Physics in the optics laboratory material in comparison with the traditional method.3 - The effective virtual laboratory program raised the practical level of performance for students in the second phase - the Department of Physics - Optics Laboratory material in comparison the traditional method.In light of this, the researcher made a number of recommendations and suggestions

The researcher believes that.this classification is very important for the following reasons : 1 - This is the first study in Iraq for the analysis of questions for the.Biology book of the seconday stagedue to the importance of this stage, which is a passport to universities and scientific life. 2 The search results can be used when a revision or re - writing books, especially the questionsat the end of chapters to introduce four levels of classification in future editions. 3 - To emphasize the importance of the questions and their effective role in the educational process, which is the cornerstone to understanding the scientific material between the covers of the book. 4 - Confirmation researcher on the comprehensiveness and credibility and objectivity of the questions through the results obtained to be taking in the future. The research frame Questions from the ends of chapters for biology books of the three levels in the Secondary stage. The research sample The research sample included three biology books of the preparatory stage. the number of key and subset questions is (615) distributed as follows : It was 161 key questions distributed as follows : 70 questions for the fourth year which new respnt 43% of the total number25 questions for the fifth scientificyearwhich is 16% and for the sixthscientific yearther are 66 questions which is 41%, while the total key questions, along with its subsidiaries were 615 questions distributed as follows : Fourth Scientific 141 question (23 %) as well as the for the fifth year the questions number is 140with percentage 23% finelly. for the sixth scientificyear the number of the questions is (334) with percent age(54%). Research tool The questions at the ends of the chapters wereclassified according to the four levels of Gallagher and Aschner classifcation (cognitive thinking, convergent thinking, divergent thinking, Evaluation thinking) The questions were classified according to the following : 1 - Determine the relative weight of the content areas of the three books in recent editions, which studied by the students for the academic year 2013 - 2014. 2 - determine the relative weight for Gallagher and Aschnerclassification. 3 - Extraction of objectivity and essay questions for each chapter of the book. 4 - Find the inclusion of questions of the goals and course material and content. 5 - Find the truth range of the content by comparing expected specifications table with theobserved specifications table. Research Results The researcher rcaches to the following results : 1 The average relative weights of the cognitive levels of Gallagher and Aschner classification for the biology books of for the preparatory level of thinking cognitive is (80%) and for the convergent thinking (19.18%), while the divergent thinking has reached (0.81%), we did not find any replicate of the level of eveluating thinking. This suggests that the High levels of thinking was not demoustvted in those books and that makes students where not familier on these types of questions. 2 - The repetition of objectivity questions was (330) paragraph (53.65%) while the repetition of essay questions was (285) paragraph (34.46%).The book that in to account the objectivity standard was takes book of the fifth grade.And then book of the sixth grade and finally the book of the fourth grade. 3 - The inclusion in the books for the Scientific Fourth and Fifth Grades has been very weak compared to the proportion of inclusiveness adopted the coverage proportion for the sixth yeam book was 84.3% The rate of the proportion of inclusiveness for all the three books was 87.68% 4 - The value of the coefficient of truthful content was very weak (0.446) when compared to what the experts think of the weights for each of the cognihve field of obsened specifications table. Recommendations In light of the research results.we necommendthe following recommendations : 1 An attention is needed for different levels of when preparing textbooks questions for the purpose of improvement and development. 2 The book questions should not be focus on the essay questions, as should include objective questions (multiple choice, matching fictures and the assertion and reason and others). 3 - The questions book should cover chapter headings in the textbooks. 4 - drafting additional questions at the end of each book of the three books take into account the standards of good questions according to the higher levels of thinking. 5 - need to adopt a specification table when preparing the questions and evaluate constantly. Proposals In light of this, the researcher suggested a number of proposals, including : 1 - conducting similar studies for the final and school exam questions for biology subject according to Gallagher and Aschner classification. 2 - conducting similar studies to the ends of chapters questions fro chemistry and physics for the secondery level. 3 - Conduct studies to show the difficulties that hinder the application of the upper levels of the evaluation like divergent thinking andevalute thinking for the exams in biology at the various stages of study

However, some of the operating and administrative functional centers do not have to have administrative or even the willingness of mental and psychological ability to understand non - specialists and do not have the necessary competence, so the development of policies that are trying to eliminate this phenomenon and the resulting disadvantages. "Forums heads are academics before everything, not administrators, but they exercise the functions of the presidency of the section without having the necessary expertise and without access to any kind of pre - training and this means ambiguity of roles they have absence of advance preparation for the Head of Department to exercise its role creates a problem in itself." (Munir : 1999.56 - 57). "The nature of interlocking and complex role of Chairman of the Scientific Section and its administrative and academic tasks, especially in the absence of job descriptions and training programs to prepare who will take the job, may give rise to perceptions of non - specific about the powers and duties assigned to, which could be hampered by the performance of some of its functions and implement some of the duties entrusted to him, and so in the belief that they fall outside the framework of the powers and duties assigned to the President of the section "(age : 1998.256). So hold many conferences that shows the importance of developing the performance of educational leaders, as in the first Scientific Conference of the Colleges of Education and Human Sciences at the University of Anbar in 2011, and highlighted what is in it that there is weakness in the level of administrative performance of most of the educational leaders in Iraqi universities and the need to improve the performance of those leaders. (First Scientific Conference of Colleges of Education : University of Anbar 0.2011). Fifth Scientific Conference and discussed at the University of Maysan, 2012, which was held under the slogan (the role of universities in the construction and promotion) discussed the development of educational systems departments and it is different from other community systems departments because the entrance to the heterogeneous and difficult to adjust and control due to the different intellectual, cultural and social levels, which requires the presence of administrative leadership effective. (Fifth Scientific Conference : Maysan University, 2012). In addition to the above has the researcher conducted a number of meetings and interviews with a number of administrative leaders in Wasit University and their assistants and heads of academic departments, and through discussions it became clear that there are problems hindering the administrative performance of the development of the Heads of Departments, including the discrepancy in the decisions and instructions of the higher authorities, a what does not help to take the right decisions, poor rehabilitation of educational leadership and not giving in to the criteria for selecting the leadership, weak employment of modern information and communication technology in administrative work, the lack of secretarial effective offices in the scientific section, lack of equal validity with placed on the head of the department responsible. Based on what was presented conferences and problems and weaknesses, and studies of the recommendations made, as well as the interview conducted by researcher The problem with current research in the administrative performance development, and as the administrative work does not evolve, but the evolution of the existing performance of the exercise, change roles so is a set of ideas and routers work and the introduction of updates and make changes designed to improve the performance of heads of academic departments at the University of Wasit mode. And which will reflect positively on the administrative functioning of the first academic work and secondly in teaching, scientific research and community service. The importance of this study is being dealt with very topic in importance, namely the administrative performance development of the heads of academic departments at the University of Wasit in light of the administrative functions based on the areas of (planning, organization, guidance, administrative communication, monitoring and evaluation). Thus is the positioning of the new study and research topics from the university's success is linked to the successful divisions, and effective leadership for scientific department is always seeking to improve its performance in accordance with contemporary management trends.

المستخلص: يهدف هذا البحث الى التعرف على اثر التدريس باستراتيجيتي التخيل الموجه والتفكير التناظري في تحصيل مادة علم البيئة والتلوث والتفكير التاملي لدى طلبة كلية التربية الاساسية. ولتحقيق هذا الهدف وضع الباحث الفرضيتين الصفريتين الاتيتين : - 1 - لا يوجد فرق ذو دلالة | The current research aims to identify the impact of teaching by forwarded imaginary and analogy thinking in the achievement of environment science, pollution and contemplative thinking by students of the Basic Education College.To achieve this aims researcher put the two nil hypotheses as the following : 1 - There is no statistical significant difference at the level ( 0.05) between the average degrees of research groups in achievement test in the environmental science and pollution subject.2 - There is no statistical significant difference at the level ( 0.05) between the average degrees of research groups in Meditative Thinking scaleResearch was conducted on the second stage students in the Department of General Science / College of Basic Education / Haditha/The University of Al - Anbar for the first term of the academic year (2014 - 2015)Researcher adopted experimental design of the two experimental groups and the control group , the research sample selected intentionally the number of research sample reached ( 60 ) students from the second stage students in the Department of Science for the academic year ( 2014 - 2015 ), The first experimental group studied by forwarded imaginary thinkink , the second experimental group studied by the analogy thinking and the third group studied by the usual way.And groups are rewarded in the variables ( achievement in biology subject by the sixth year secondary school , and chronological age - month period , intelligence and thinking contemplative previous information, and back ground education by the parents). The experiment term study lasted by two lessons a week for each group , and the researcher himself teach research groups.The achievement test was built in the environment and pollution science of (45) subjective items, multiple choice , and (5) essay item , were verified from its sincerity by submit on a group of arbitrators , then applied on a prospective sample to make sure the clarity of its items and were confirmed its stability also has been discrimination coefficient, and the coefficient of difficulty of items and effectiveness of false alternatives.The researcher adopted a measure of Meditation thinking by Eysenk Wolsen after his translation , which consists (30) items , (20) items of the total items represent a positive mediation thinking while the rest (10) items representing negative. To ensure the veracity of the scale display on a group of specialists to judge the goodness in measuring the capacity to be measured and adopted 80% and above of the items on the validity of the scale.Then applied on exploratory sample to make sure the clarity of its items, and the account of stability coefficient, then after the data were analyzed and processed statistically and yielded the following results : 1 - A statistically significant differences at the level of significance ( 0.05) between the average scores of first students experimental group studied in accordance with the forwarded imaginary and strategy control group in favor of the experimental group students who have studied according to the imagination strategy in achievement test2 - There is no difference is statistically significant at the level of significance ( 0.05) between the average scores of students second experimental group which studied strategy of the analog thinking and the average score of the control group which studied the usual method in achievement.3 - There is no difference is statistically significant at the level of significance ( 0.05) between the average scores of students the first experimental group studied the strategy of forwarded imaginary and average grades second experimental group which studied the strategy of analog in the achievement.4 - Statistically significant differences at the level of significance ( 0.05) between the average score for the first experimental groups studied according to the forwarded Imitation and the second that studied the strategy of analog thinking in the development of meditation thinking test.5 - There is no difference statistically significant at the level of significance ( 0.05) between the average scores of the first experimental group which studied by strategy forwarded imagery and the average of second experimental group which studied by analog thinking in development of meditation thinking.In light of the search results, researcher came out by a number of conclusions, recommendations and suggestions
