المستخلص: his study aimed investigating the cytotoxic effect of crude enterotoxins on normal and cancer cells both invitro and invivo. the present study included isolation and identification of Pathogenic Escherichia coli, From Children (under 3 - years for both sexes) infected with severe diarrhea, from March to June 2005, and as follows : *Sixtysix Islates (60%) were obtained from 110 samples. These Isolates were Identified according to morphological and biochemical tests, and for confirmation by Api - 20E System. *Serological identification for these Isolates( 66 isoleates )showed that only 12 (18%) isolates were belonged to Enteropathogenic group of E. coli.(EPEC).* The results of using Suckling Mouse Assay(SMA) showed that only 13 (19.6%) out of 66 Isolates were capable of producing heat - stable (ST) enterotoxin, therefore these isolates belonged to Enerotoxigenic group of E.coli ( ETEC).Whereas the EPEC isolates were all negative for this test. According to the toxin activily that was evaluated by (SMA) the Isolate No. 99 determined as the most efficient Isolate in producing the (ST). The same Isolate (99) of E. coli showed its ability to produce heat Labile enterotoxin (LT), by using Rabbit lileal Loops.The Isolate (99) revealed for sensitivity to Ampicillin, Gentamicin, Nalidixic acid and Nitrofurantoin antibiotics, but resistance to Amoxicillin , Cefixime, Cephallothin, Ciprofloxacin and trimethoprim.This Isolate also showed its ability to adhere by using the special media that contain the congo red stain, and by using hemagglutination test because it posseses the colonization factors antigen (CFA/1) and CFA /III However it failed in producing hemolysin enzyme that hemolyze red blood cells The toxin reserved Its activity at temperatures (20,40,60 and 80)c0 , but loss some of its effect at 100 c0 and kept its activity at 4 c0 for (24 - 48) hrs, It was found that the highly toxic activity reduced in the PH 5,9.5. The time ofmice response to enterotoxin was determined. At 90 minutes, as the maximum of response and 180 minutes as the optimum time of response. Enterotoxin was purified partially by using sepharose CL - 6B, and the molecular weight for (ST) was 17378 dalton. LD50 of both bacterial Suspension and crude enterotoxin in mice was 2.13 × 108 cell/ mice, and 48.75 mg/ mice respectively. The crude enterotoxin showed more severe effect than the bacterial suspension in spleen, Intestine, and Lung, while the effect of bacteria suspension was more severe in Liver.The therapeutic dose of crude enterotoxin was determined according to LD50 in mice it was revealed that the concentration of 390 mg/kg have the activity in reducing the tumor volume when injected directly in tumor, with an inhibition ratio between(83 - 89)% beginning at 8th day of the 25th injecting days. While when the toxin was injected intraperitonealy, the inhibition ratio of tumor was Less than the injection in tumor it self. The dose 97.5 mg/kg that given daily for 25 days showed more efficiectly in reducing the tumor in percent of 73.3. The Comparitive study between the relative volume of tumor in treated group and the relative volume of tumor in control group revealed that there was significant difference statistically important all over the treatment time.. The necrosis and fibrosis were the most important characteristics in treated groups after histopathological examination which appearantly with the progress of treatment associated with volume decrease of tumor, so it was found that the last stage of treatment showed the cancer cells presented like small Land Surrounded by dense fibrous tissue. The treatment by using all toxin concentration in both ways of injections on murine bone marrow cells, showed significant increase in blast Index (BI) and mitotic Index (MI) when compared with control.The toxic effect of crude extraction was studied in tumor cell lines (in vitro), Hep - 2 and AMN - 3 and the normal cell line REF, the study showed that the toxic effect depend on the type of cells, the dose and the time of exposure. This study revealed that the AMN - 3 Cells were more Susceptible from that of Hep - 2 Cells and the high concentration caused inhibition to the growth of the tumor cells, Specially the concentration of 60000 Mg/ml, Also growth and multiplication of REF cells. Whereas the concentrations of 1875and 3750 Mg/ml were found as an inhibitor to REF Cells. Partially purified enterotoxin (ST) showed that it's effect was found to in hibit Hep - 2, AMN - 3 and REF cells at 72 hrs of exposure and has an inducer effect to growth of cells at 24 hrs of exposure in all concentrations,but the effect was differ in the time of exposure at 48hrs,that the three concentrations (1.986,3.965and 7.95) Mg/ml showed inducing effect ,while the three hight concentrations(15.86,158.6 and1586) Mg/ml showed inhibition effect to AMN - 3 cells.Also the hight concentrations(30000 and 60000) Mg/ml werefound as inhibitor to REF cells at( 48,72)hrs,but they were inducer of growth at 24hrs of exposure. The toxicity effects of crude enterotoxin were studied in human Lymphocyte multiplication (in vitro) , and the higher concencentration showed decline in Mitotic index (MI), but It was induced cells to transform in present of mitogen, so there was inverse in blast index (BI) when compare with the control.

The response of the NE213 detector for neutrons is formed not merely due to the neutrons elastic scattering on hydrogen nucleus. The response function shape also depends on proton leakage from detector volume, double scattering on hydrogen and scattering (elastic, inelastic) on carbon nuclous. The proton leackage is an edge effect, which is most important for small volumes of scintillator detectors.The program has been written in FORTRAN - 77 language. The calculations results were compared with experimental data of the efficiency measurements, for eight NE213 (8.5 × 100)cm liquid scintillator detector.One can see a good agreement between our results and the experimental data. Finally, the average percentage error of the efficiency values in our calculations results was less than (2%).

المستخلص: Arabic is one of the ancient living languages in the world. It has gained great attention that no any other language has gained from the scholars. This degree of attention has its own reasons. It is the language of the glorious Qur’an, the sacred book of Muslims. Thus, it has achieved its sacredness through its relevance to this great book. Understanding the purposes of the linguistic discourse was the objective of the researchers. So understanding the syntactic structures of Arabic and apprehension of its linguistic phenomena were the priority of the issues taken care by old linguists. The linguistic study has attained its higher standard earlierly, and the grammatical level was the most interesting one among the other levels tackled by scholars. The grammatical lesson began simple and easy on the hands of Arab scientists. Like any other science, being easy first, then it starts becoming complicated in research. This same description can be applied to Arabic. It has become complicated and a number of foreign trends such as logic, philosophy and philology, have penetrated into it. Then, it has be come a normative prescriptive lesson, away from being descriptive besides the obvious difficulties of approaches which made it difficult. So that scholars found it wise to escape. Since language is one of the means of learning and thinking, one can realize the sufferings faced by learners. So the voices were raised and complaints heard about the difficulty of the grammar lessons. This led to the appearance of a call for simplification. Old Arab grammarians have their attempts in this respect and they have written grammatical briefs and didactic poems to facilitate keeping the grammar of language by heart yet, Sibawayhi’s Book is still the controlling source which governs our grammar. The briefs and poems have no longer the power to meet the requirements of the grammar lesson. Even the old publications however scientific they are, cannot remedy the miserable. A number of scientific scholars have undertaken this task. Their endeavor has been welcomed recently. And as much as possible they have made use of the old attempts such as that of Ibn Madha’a Al - Qurtubi (592H). Really, one of the modern remarkable attempts may be that of Ibrahim Mustafa whose opinions have their obvious influences on the modern grammatical lesson. He tries to depend on meaning when interpreting linguistic phenomena. As far as he got rid of the theory of grammatical operator (al - a’amil), which was the basis for grammatical lesson that governed and complicated it, he was agreed by plenty of scholars such as Dr.Ahmed Abdulsattar Al - Juwari and Dr.Mahdi Al - makhzoomi and others. Since Arabic is an inflected language, one can imagine the difficulty faced by the researcher to facilitate its grammar. Really, no language can be simplified, but there are a group of ideas through which the linguists try to interpret the linguistic phenomena and this should be the concern of the researcher. These attempts showed extreme criticism and they were not free from some shortcoming. This study tries to shed light on these attempts and simplifies Arabic grammar comprehensively. We have discussed the difficulties of Arabic grammar and the reasons beyond that, in addition to grammar, its evolution and development as well. The study has also tackled thoroughly the phenomenon of parsing in Arabic, and the attitude of the old grammarians towards this phenomenon. The researcher has carried out an analytical study of the researchers’ opinions in simplification to be aware of the value of these opinions, and whether they can be a right nucleus to a simple and easy grammar lesson. It is not easy to achieve that because of the width of the scope of the research, greatness of differences and abundance of Arabic produced knowledge in the field of grammar. Clearly, the shortage of the serious analytic knowledge of simplification in this area, led the researcher to carry out this type of study characterized by modernity and scientificness trying to find out the essence of the notion of simplifican and main elements which guided the scholars to come out with conclusions and recommendations to serve Arabic language and support those who study it. God is beyond our purpose

المستخلص: ان تعلم اللغة الانكليزية في الوقت الحاضر يعتبر المفتاح الذي يفتح العديد من الابواب امام اي مهني. يرغب عدد اكثر واكثر من الناس الذين لم يتعلموا هذه اللغة من قبل ان يتعلموها ليكونوا متابعين للتغيرات المستمرة . نلاحظ ان العديد من مدرسي اللغة الانكليزية في العالم تم استدعائهم للتدريس في اماكن مرتبطة بمهنة ما. تقدم هذه الكورسات بشكل عام للبالغين من الطلاب الذين يتقاسمون اهتمام وظيفي مشترك بتعلم اللغة الانكليزية , وهذا ما يدعى باستخدام الانكليزية لاغراض خاصة.يعرف مصطلح الانكليزية لاغراض خاصة كطريقة تتمحور حول المتعلم لتدريس الانكليزية لغة اجنبية او لغة ثانية والتي تم تطويرها منذ 30 عاما. انها تلبي حاجات المتعلمين البالغين الذين هم بحاجة لتعلم لغة اجنبية لاستخدامها في مجالاتهم الخاصة , مثل العلوم , التكنولوجيا , الطب والتعليم الاكاديمي. يوصى بالبرنامج الحالي لتدريس اللغة الانكليزية لاغراض خاصة لموظفي جامعة بغداد ولاختصاصي اللغة الانكليزية الذين يرغبون بتعلم كيفية تصميم الكورسات والبرامج التي تستخدم لتدريس الانكليزية لاغراض محددة كل حسب مجال اختصاصه مثل الانكليزية في مجال الاعمال , الهندسة المدنية, الاغراض الاكاديمية وكذلك لاغراض الخدمة الصحية. علاوة على ذلك تقديمهم لما يتعلق بالانكليزية لاجل اغراض خاصة مثل الاستراتيجيات التعليمية او التوجيهية, تكييف وتطوير المواد, التقييم.طبقا لذلك فان الموظفين في جامعة بغداد بحاجة لدراسة كورس لغة انكليزية لاغراض محددة تلبي احتياجاتهم المختلفة ومتطلبات عملهم, وعلى حد علم الباحث فانه لم بتم تحليل حاجات المتعلمين ومتطلبات عملهم, وتبعا لذلك لم يتم تصميم اي كورس لتطوير اداء الكادر الوظيفي في الجامعة وفقا لهذه المعايير. وهذه هي المهمة التي ستقوم بها الدراسة الحالية, اي ان البحث الحالي يهدف الى ملء هذه الفجوة. ولتحقيق اهداف هذه الدراسة, قام الباحث باعداد فقرات استبانه ومقابلة. تتالف هاتان الاداتان من اسئلة مختلفة والتي تبحث عن معلومات حول احتياجات الموظفين الخاصة والمختلفة ومتطلبات عملهم. لتامين صدق فقرات هاتان الاداتان, تم عرضهما على مجموعة من الخبراء والاختصاصيين. وحسب الثبات باستخدام معاملة بيرسون لحساب معامل الارتباط. استخدمت النسبة المؤية لحساب اجابات افراد العينة. بعد تاكيد صدق وثبات فقرات الاستبانه والمقابلة, قام الباحث ببناء البرنامج المقترح وقد تم تامين صدق البرنامج من خلال عرضه على عدد من الخبراء والمختصين. في ضوء تحليل ومناقشة النتائج استنتج الباحث ما يلي : 1. اللغة الانكليزية مطلوبة بشكل خاص لاجل اغراض وظيفية.2. يحتاج الموظفين لكل مهارات اللغة, اي الاصغاء, التكلم, القراءة, والكتابة. 3. يتم التركيز في اختيار مواد كورس تدريس اللغة الانكليزية لاغراض خاصة على بعض جوانب اللغة كالمفردات والقواعد.4. هنالك حاجة لكلتا اللغتين العربية والانكليزية في شرح المواد.5. ان الهدف الرئيسي من وراء تدريس اللغة الانكليزية لاغراض خاصة لموظفي جامعة بغداد هو لتمكين المشاركين من التحكم او السيطرة على المهارات الاساسية في الاصغاء, التكلم, القراءة, والكتابة بطريقة تلائم اهداف ومتطلبات وظائفهم.وفي ضوء نتائج الدراسة, يوصي الباحث بالاتي : 1. يجب ان يحتوي منهاج تدريس اللغة الانكليزية الذي صمم للمتعلمين في كليات جامعة بغداد على كورس لتدريس الانكليزية لاغراض خاصة والذي يتوقع استخدامه لاغراض وظيفية مستقبلية.2. يمكن استخدام تحليل حاجات الموظفين والذي تم القيام به وتحديده في هذا البحث كاساس لاي محاولة لتصميم برنامج جديد لتدريس اللغة الانكليزية لاغراض خاصة. يحدد هذا التحليل الاهداف والحاجات الرئيسية للموظفين.3. ان البرنامج المقترح لتدريس اللغة الانكليزية لاغراض خاصة يمكن اعتماده حتى لموظفي بقية الجامعات والوزارات والمؤسسات. | Nowadays to learn English is a key that opens many doors for any professional man. More and more groups of people who haven’t learned this language before require to knowing it to be updated with the continuous changes. We see that many English teachers around the world are called on to teach in career - related settings. These courses are generally integrated by adult students joined with a common professional interest in learning English. This is English for specific purposes.English for specific purposes is known as a learner - centered approach to teaching English as a foreign or second language that developed about 30 years ago. It meets the needs of mostly adult learners who need to learn a foreign language for use in their specific fields, such as science, technology, medicine, leisure, and academic learning. The current ESP course is recommended for the personnel at the University of Baghdad and foreign and second language professionals who wish to learn how to design ESP courses and programs in an area of specialization such as English for business, for civil engineering, for academic purposes, and for health service purposes. In addition, they are introduced to ESP instructional strategies, materials adaptation and development, and evaluation.In post - April - 2003 Iraq, the English language has undergone radical changes in both status and orientation. English as a second language has been gaining ground and attitude. The use of English has rechecked in the last two years and the need for it is becoming more and more, a necessity in everyday life. The increasing use of computers and the International Web has made English a must for government personnel, especially those in the academic milien. Accordingly, Personnel at the University of Baghdad need to study an English course for special purposes that meets their different needs and their job requirements. To the best of the researcher’s knowledge no analysis of the learners’ needs and job requirements has been carried out and subsequently no course has been devised to develop the University staff’s performance according to these criteria. This is a task the present study has undertaken, i.e., the current research aims at filling this gap.In order to achieve the aims of this study, the researcher has constructed a questionnaire and an interview. These two instruments consist of different questions that seek information about the employees’ different personal needs and their job requirements. To ensure the validity of these instruments, the researcher exposes them to a number of experts and specialists. Reliability is computed by using Pearson’s formula for correlation coefficient. The percentage is used to calculate the subjects’ responses. After ensuring the validity and reliability of the questionnaire and interview, the researcher has prepared the proposed programme. The validity of the proposed programme has been ensured through its exposure to a number of experts and specialists. In the light of the analysis and discussion of the results, it has been concluded that : 1. English is required basically for occupational purposes.2. All the skills namely, listening, speaking, reading, and writing are needed by the personnel.3. In selecting materials for an ESP course, certain language aspects such as grammar and vocabulary have been focused on.4. Both Arabic and English are needed to explain the materials.5. The main objective behind teaching an ESP course for the employees at the University of Baghdad is to enable the participants to manipulate the basic skills of listening, speaking, reading, and writing in such a way as to satisfy the objectives and requirements of their jobs.In the light of the results and the conclusions, the researcher recommends the following : 1. The ELT course to be designed for the learners at the University of Baghdad should include an ESP course that is expected to be used for occupational purposes.2. The personnel needs analysis that has been carried out and outlined in this investigation could be used as a basis for any attempt to design a new ESP programme. This analysis characterizes the main objectives and needs of the prospective personnel.3. The suggested ESP programme is reliable even for the employees of other universities, ministries and establishments.

These crystals may aggregate and provide a nidus for the formation of renal stone ( Nephrolithiasis ). This study was performed to explore the diuretic effect of Rowatinex , Hydrochlorthiazide and some medicinal plants ( corn silk , celery , barley and senna ) , and there effect in attenuation or prevention of the development of nephrocalcinosis in an experimental model .Fourty - two local domestic rabbits were used in the present study , they were divided in to seven groups . One group was used as the control in which oxalic acid in a dose of 333 mg /kg orally was given to induced nephrocalcinosis . Other groups were treated two hours before induction by one of the above mentioned agents for each group . nephrocalcinosis was assessed by estimating blood urea nitrogen ( BUN) , serum creatinine , potassium and sodium , urine calcium inaddition to general urine examination on two occasions : 1 day and 10 day after induction , also the histopathological examination of the rabbits kidney in the last day of experiment to detect the improvement in the treated groups in comparison to the control group . Animals pretreated with Rowatinex ( 200 mg/day ) orally and continued on the same dose for successive 10 days after induction , had a significant lower level(p<0.05) of BUN, serum creatinine ,potassium and higher level of serum sodium also elevation of urine calcium due to the diuretic effect of Rowatinex , also the histopathological examination showed a well improvement in comparison with the control group . Pretreatment with Hydrochlorthiazide ( 1 mg/kg body weight ) orally in a single dose before induction caused a significant lowering (p<0.05) of BUN , serum creatinine and potassium and prevention of hyponatremia , also significant lowering of urine calcium also the histopathological examination which showed a notice improvement in comparison to the control group but it is less than that produced by Rowatinx. Aqueous extract of Corn Silk (1 gm /kg / day ) orally given before induction and continued for successive 10 days cause a significant lowering ( P<0.05 ) of BUN , serum creatinine , potassium and prevention of hyponatremia also elevation of urine calcium level due to it is diuretic effect . In addition to the histopathological examination which showed a significant improvement in this case .Pretreatment with aqeous extract of fresh Celery ( 8 gm /kg / day ) add to the animal food continued on the same dose for 10 days after induction produced a significant ( p<0.05 ) reduction in BUN , serum creatinine , potassium level and prevention of hyponatremia , while elevation of urine calcium level as a diuretic effect and the histopathological examination which showed an improvement and reduction of the severity of nephrocalcinosis .Pretreatment with aqeous extract of Barley ( 1 mg/kg /day ) given orally and aqeous extract of Senna ( 1 gm /kg /day ) given orally and continued for 10 successive days also showed a significant ( p<0.05 ) reduction of BUN , serum creatinine , potassium and prevention of hyponatremia in addition to increase urine calcium level . The histopathological examination showed a a notice improvement in comparison to the control group , but inspite of this improvement there is also a side effect compined with using Senna which is represented by diarrhea which is due to the known purgative effect of Senna . And as aconclusion , the results of the previously mentioned drugs and medicinal plants showed a significant diuretic and attenuating effect on the induced nephrocalcinosis at the tested doses , so there is a possibility of using these agents in the treatment of this model of nephrocalcinosis with apossible preventive opportunity in patients at ahigh risk of developing nephrocalcinosis and may also with a long course of treatment help patients with renal stone disease .

المستخلص: Prostate - specific antigen (PSA) is a serine protease expressed at high levels in prostate epithelium & elevated PSA in serum is well established marker of prostate cancer. Recently, the relative proportions of free PSA & PSA complexes to α1 - antichymotrypsine have become important variables in distinguishing between prostate cancer & benign prostatic hyperplasia (BPH). Numerous studied have demonstrated the production of PSA in female tissues e.g. breast & low levels of PSA are present in female sera.In this prospective study, we measured the levels of total PSA by mini VIDAS machine in the sera of 45 newly diagnosed breast cancer female patients & correlated these with selected clinicopathological variables includes : - Patient’s age, menopausal status, tumor size & volume, histological type & grade of the tumor , lymph node status & steroid hormone receptor status.The detected level of total PSA in the sera of healthy control was <0.07 ng/ml. About 35.6% of the total cases of women with breast cancer showed a higher levels (≥0.07 ng/ml) of total serum PSA.Chi - square & T - tests were used to identify the significance of association between total serum PSA levels & the clinicopathological variables. However, it has been found a significant association (P<0.05) between the level of total serum PSA & patient’s age, menopausal status, lymph node status & steroid hormone receptors (estrogen/ progesterone receptors).On the other hand, it has been identified there was no significant association (P>0.05) between the levels of total serum PSA & tumor size & volume, & histological type & grade of the tumors.We concluded that total serum PSA cannot be used as a screening program for early detection of breast cancer, but may be useful in close follow up the patients & may have a prognostic guide to response to the type of treatment.According to the results of our study, we recommend further study include larger sample size, combination of total serum PSA with other tumor marker.

المستخلص: It is well documented that intake of highly concentrated dose of ethanol has injurious effect on gastric mucosa. Many mechanisms have been implicated in the pathogenesis of gastric lesions induced by ethanol. Some drugs and aqueous extract of medicinal plants were used in the current study to explore their effectiveness and whether may be helpful to reduce the injurious effect of ethanol and to produce possible gastric cytoprotective action.The parameters of gastric mucosal lesion were measured before and after administration of Lansoprazole, aqueous extract of Curcuma, Marshmallow, Slippery Elm, Calendula, Chamomile and Garlic , In addition to measurement of the serum glucose, calcium ,potassium and sodium levels and the possibility of having any change in their values after administration of ethanol. The obtained results can be summarized as the following : - • Ethanol was found highly effective to induce gastric lesion in ratio of 100% when administered orally. This effect was associated with significant rise of serum glucose level and decrease of calcium level but with no significant change in serum levels of potassium and sodium.• Lansoprazole is one of proton pump inhibitors (0.04 mg/kg) was given orally 1 hour before ethanol administration produced highly significant reduction in gastric lesion parameters with preventive index equal to 95% and suggestive a possible cytoprotective property of the drug. This effect was accompanied with slight increase in glucose level and insignificant change in serum calcium, potassium, and sodium levels.• Curcuma its aqueous extract has antioxidant effect, 1.5 ml was given orally, produced highly significant reduction in gastric lesion parameters with preventive index equal to 93% and this effect was associated with no significant changes in the serum glucose, calcium, potassium, and sodium levels.III• The aqueous extract of Marshmallow, Slippery Elm, Calendula and Chamomile 1.5 ml was given orally for each, produced significant decrease in gastric lesion parameters with preventive index equal to 42%, 46%, 14.6% and 15.8% respectively. This effect was associated with significant increase in serum glucose level of the first two plants and with significant decrease in glucose level of the later twoplants .There is no significant changes in serum calcium, potassium and sodium levels of these medicinal plants except Chamomile.• The aqueous extract of garlic 1.5 ml was given orally produced significant rise in gastric lesion parameters which completely differ from the effect of other medicinal plants. This effect was accompanied with significant reduction in serum glucose and potassium levels.The obtained results in this study indicated that all medicinal plants except garlic have beneficial cytoprotective action on the gastric mucosa and the possibility of using these plants in clinical trials as gastric cytoprotective remedy for patients with gastric ulcer.

المستخلص: The aim of this study is (forecasting the precipitation by using cloud cover data in Iraq). To achieve this goal, the properties of low, medium and high clouds affecting Iraq mounted (27) types are studied through their diffusion percentage (coverage), base height, types and the relation between each of these properties and rainfall with its five shapes (drizzle - rains - snows - heavy showers and thunderstorms). for eight climatic stations from Iraq (Mosul, Kirkuk, Baghdad, Rutba, Al - Hay, Diwayniya, Nasiriya and Basra).The research results were reached the following points : - Concerning the clouds' properties like their diffusion percentage and base height, the results have proved that the season difference affects these two properties greatly where the diffusion percentage of the clouds increases during winter and decreases during spring and autumn, also the base height of the clouds decreases during winter and increases during spring and autumn. - As to the nine types of low clouds, it is found that they do not appear evenly for some types appear more than the others.Generally, the types of low clouds that hold the characteristics of the layered clouds and the accumulated clouds are the most apparent types in Iraq weathers such as the layered accumulation clouds on one hand. The appearance of types with the layered shapes increases during cold months (winter), whereas the appearance of types with accumulated shapes increases during moderate months (spring and autumn) on the other hand. - For types of medium clouds, their appearance average also varies according to their types. The appearance of the layered types increases during winter and the appearance of the accumulated types increases during spring and autumn, too. - The high clouds are characterized with their all nine types being at the peak of appearance averages during spring, autumn then winter.The results, related to the relation between rainfall and its types with the clouds' base height, prove that there are heights for clouds' bases contribute largely in forming rainfall and its shapes Vs the non contribution of other heights except with too little rates of rainfall. Regarding the relation nature between rainfall and its shapes with low and medium clouds, it is clear that not all types of low and medium clouds are unproductive for some types are greatly responsible of forming rainfall compared to other types thathave a too little role, on one hand. It is found that there are certain types of clouds responsible of certain types of rainfall and its shapes, on the other hand. In order to complete the picture concerning this subject, the analytic method of flat and upper maps air for the two pressure levels (850 - 500) Millibar is used to define the types of the flat and upper pressure system responsible of forming the types of clouds and their height forming in tum different rainfall shapes. The results have proved the existence of a certain order for those different pressure systems during the formation of a certain shape of clouds and rainfall. This order is exposed to change during the occurrence of another shape of rainfall. These changes can be used for future forecast of various rainfall shapes. In addition, T t/> gram diagram is used to define the thickness and height of chosen types of low and medium clouds functionally through following ·up the temperature of air and dew point.

المستخلص: Most of developing countries suffered from economical crisis in 1980s of the last century which was caused by the external debts. In order to avoid this crisis and to rectify imperfections in economy, these countries tended to. Implement recitification programs that has led to change the economical policies that were implementel baler. Recenty, Jordan has tended to Privatization and the main reason for that are the economical crises from which Jordan has suffered. So, Jordan adapts rectification policies, the most important of which is Privatization policy as a result of unsatisfied Performance of the Public Sector, This study aims at : 1 - Evaluation privatization impacts on Jordan general budget.2 - Studying the of privatization on some general economical remarks in Jordan economy. This study involves four chapters : The first deals with the concept of privatization, its aims, techniques and the obstacles it was faced by. The second chapter deals with presenting and analyzing on Jordan general budget. The third chapter deals with the direct impacts of privatization on Jordan general budget, Finally, the third capter presents the indirect impacts of privatization on Jordan general budget. This study leads us to infer some conclusions, the most important of which : 1 - One of the most important reasons that makes the Public sector companies failing at performing its duty is the laws and instructions by which these companies are working since these laws and instruction limited the activity of public sector companies. 2 - Privatization process has led to decrease the general external debt of the national grass product from 223% in 1989 to 78. 4% in 2001 Also, this process has led to decrease the general internal debt of the national gross product form 41% in 1989 to 22% in 2001 which has positive impact on the general budget. This studs steers the researcher to the following recommendations. 1 - To motivate the private sector for investment, there is necessity, for a legal background that protects it and saves the capital. In addition to profits of the investment process. 2 - Gradual preenting of interests for the privatized companies in the stock market to get the best income. That is because presenting the whole interests may cause a decrease in their prices. Consequently, the price of buying the government companies lass than the compete price.

المستخلص: ان المسالة المهمة والرئيسة في التطبيقات الاحصائية تتمثل بمعرفة التوزيع الخاص بالمجتمع المطلوب دراسته ومعرفة خصائص ذلك المجتمع كي يتم تمثيل المجتمع تمثيلا سليما من خلال استعمال الاساليب الاحصائية الشائعة.في بعض مسائل الاستدلال الاحصائي المدروسة يتم افتراض | In some problems of statistical inference considered, we assumed that the distribution of random variable being sampled is known except, perhaps for some parameters.In practice, however, the functional form of the distribution is seldom, if ever, known. It is therefore desirable to devise some procedures that are free of or depending on few information or assumption concerning distribution.In this dissertation we demonstrate and study some procedures that are commonly referred to as nonparametric or distribution - free and also semiparametric methods.The term “Distribution - free” refers to to the fact that no assumption are made about the underlying distribution except that the distribution function is absolutely continuous.The term “Nonparametric” refers to the fact that there are no parameters involved in the traditional sense of term parameter used thus far.The term “Semiparametric” refers to combine the parametric term with nonparametric term, which there is few information or assumption about the distribution function.In chapter one we demonstrate an introduction to the problem, the main of the study and the historical review.In chapter two we demonstrate several nonparametric and semiparametric estimators for probability density function and these estimators are “fixed kernel which use fixed bandwidth or smoothing parameter, variable kernel which use variable bandwidth for each observation, semiparametric estimator which combine between two estimators {parametric by using of MLE and nonparametric estimator by using of fixed kernel}”.Beside these estimators we suggest four estimators like semiparametric estimator but the first suggestion combine MLE & variable kernel, the second suggestion combine two nonparametric estimators, the third suggestion combine robust estimator (for the mean & variance) with fixed kernel estimator, Finally we suggest estimator that combine robust estimator with variable kernel.Beside to above we demonstrate several estimators for smoothing parameter or bandwidth one of these estimators suggested from the author.Then we make a comparison between the parametric, nonparametric and semiparametric estimators with respect to bandwidth estimators by using simulation experiments, depending on different distributions (Normal, Lognormal and bimodal), different sample sizes and variances.We find that the best estimator for the density function is the first semiparametric estimator when we are using the 1st & 2nd distributions (Normal & Lognormal) except in few cases where we find the 1st suggested estimator is the best. And when we are using the 3rd distribution (Bimodal) we find that, the 2nd suggested estimator (Nonparametric estimator) are the best except in few cases where the other suggested estimators beside to 1st semiparametric estimator are the best.Also we find that the (BCV) estimator is the best estimator for the smoothing parameter when we are using the 1st distribution (Normal), except in few cases where the OS estimator is the best for h.For the 2nd distribution (Lognormal) we find the (LSCV) estimator is the best estimator for the smoothing parameter.Finally, For the 3rd distribution (Bimodal), We find that the (BCV) estimator is the best estimator for h except when the sample size equal to 100 (n=100), where the (DPI) estimator is the best.

المستخلص: خلال العقد الاخير من القرن العشرين بعض المنظمات صنعت تاريخا بينما الاخرى اصبحت تاريخا، وذلك بسبب ان الاولى اهتمت بمواردها غير الملموسة، مثل، المعرفة وراس المال الفكري، بينما الثانية اهملتها واعتمدت فقط على الموارد الثابتة. ونظرا لاهمية الموارد غير الملموس | Over the last decade of twentieth century, some companies have made history, while others have became history. Because the first have given priorities to intangibles, like (Knowledge and Intellectual) and others had neglected it, depending on their existed resource only. For the importance of the intangible resources, organizations have created specific management units, called “Knowledge management” which give high attention to that resources. Environments is continually exceeding in complexity, in the same time technological development continuous and exceeding change, in addition to a crossing cultures, in such situation, knowledge management became unable to support organization knowledge needs because it take care in internal function and activities only, and ignore the outside environment. According to that environmental pressure and its threat, organizations should adapted, to do that organizations created comprehensive knowledge management (CKM) which cares about internal and external organizational environment in the same time. (CKM) is a hole philosophy which aimed to pursue and support intangibles and systemic knowledge, and in the same time give importance to intellectual capital (IC) which considered the main creator of knowledge. The (CKM) has four basic approaches : Internal efficiency approach, information systems approaches, personnel efficiency approach and (IC) approach. (IC) has been chosen as a moderate variable between the independent variable (CKM) and dependent variables (Organizational effectiveness).The research is divided in to two major parts : First side : Theoretical part which has shown in two chapters, the first one shows previous studies and the methodology of the research. The methodology contains research problem which summaries the necessity of the benefit that organizations can get from there intangible resources. Three major hypotheses have emerged from research problem, with many branch hypothesis have followed as follow : The second chapter was titled “the research theoretical, frame work, (CKM, IC, And organizational effectiveness). This chapter takes in details the meaning of (KNM) and the difference between it and the partial KM. the chapter in the same time shows its basic philosophy and explain its variables measure. There are high importance to (IC) especially about its meaning. Second side : practical side : In this side the research measured the hypothesis which depending on information had collected from electric sector by questionnaire, which was considered as a basic instrument to collect information. In addition the researcher used many others ways for this purpose, like interview and documents. Third chapter had describe and analyzed research variables according to sample response. The fourth chapter shown result analysis and hypothesis approval. The last part of this chapter explained the importance of the effective variables and its priorities. The fifth chapter was appalled for results, recommendations, and suggestions. The researcher used many statistical instruments to improve the right or wrong of hypothesis, the importance among them are : simple & multiple regression, Path analysis, factor analysis, Canonical correlations. The research has reached many results, the most important among them are mentioned below : A - all major and branch hypothesis have significant impact on organizational effectiveness and (IC).B - the impact of (CKM) on organization effectiveness accordance (IC) is more than the impact with out (IC).C - intangible resources have a high importance in increasing organizational effectiveness.D - Organizations which researched do not give suitable carefulness to their intangible resource.At the end the researcher give many recommendations : 1. Organizations should give large carefulness to knowledge because it is a power, otherwise its power will be usefulness.2. Organizations must established (CNM) which maintain knowledge and adapt (IC) according fixed technology.3. A high attention should be given to human capital as it is the most importance part in (IC).4. Organizations priorities should be listed according to their mission and strategies.5. Giving the structural capital and relation capital for purpose of (IC).6. Organizations must sharing in knowledge portfolio knowledge to success and servile.
