يهدف البحث إلى إدخال صف جديد من التوابع العقدية رمزنا له بالرمز يعتمد في تعريفه على تعريف صف هولدر الشهير ,حيث قمنا بدراسة العلاقة بين الصف الجديد وصف هولدر ومن ثم اثبتنا بعض الخواص التي يتمتع بها الصف . وفي النهاية قمنا بتطبيق هذه الدراسة لتقريب صف التوابع على منحنيات مغلفة تنتمي الى اسرة واسعة من المنحنيات . This research aimed to define a new class of complex functions , which depends in its definition on the definition of famous Holder class. We studied the relation between the new and Holder classes, then we proved some properties of the class . We finally applied this study to approximate the class of complex functions on closed curves , which belong to a wide class of curves.

حُضِّر مسحوق الفرايت ،حيث (x= 0.5) بالطريقة السيراميكية التقليدية ثنائية التلبيد ((CCDS. وحسبنا ثابت قوة الاهتزاز K للمواقع الرباعية والثمانية في شبكة الفرايت، و ثابت المرونة C11 ، ومعامل الانضغاط B . كما تم حساب سرعة الموجة المرنة الطولية والقصية وفق اتجاه أحرف البلورة المكعبية للعينة. بعد ذلك، حددنا تردد عتبة الانتقالات الالكترونية من طيف IR. علاوة على ذلك، تم حساب الحركية الجرية في المواقع الرباعية والثمانية، وتغيّر عزم ثنائي القطب المغناطيس للرابطة - . تم رسم العلاقة بين المساحة تحت القمم الماصة للحرارة (الانتالبية) في مخطط التحليل لحراري التفاضلي والوزني TG/DTA مع تغيّر الوزن TG%، وكذلك السعة الحرارية للعينة تحت ضغط ثابت Cp مع درجة حرارة معالجتها. ولوحظ أن لهذه السعة الحرارية قيمة حدية عند درجة الحرارة 175 .ferrite (x=0.5) was prepared by a well-known conventional ceramic double sintering method (CCDS). Force constant K was calculated for tetrahedral and octahedral sites. The elastic constant C11, bulk modulus B , longitudinal and shear wave velocities were calculated. Threshold frequency for electronic transition was determined using IR spectra. In addition, the drift mobility for tetrahedral and octahedral sites, as well as magnetic dipole moment changes for - bond were determined. The area beneath endothermic peaks was correlated to the weight change TG%. On the other hand, the heat capacity under constant pressure CP was correlated to sample treatment temperature. It has been noticed that the CP has a critical value at 175 .

أنجزت اختبارات الإصدار الضوئي التجاوبي على بلورة البيروفسكايت TbBaCoO3 عند درجة حرارة الغرفة من أجل سطوح مكشوطة حديثاً. استخدمت طاقة بداية التجاوب عند العتبةCo3p→3d لتحديد مساهمة الالكتروناتCo3d في عصابة تكافؤ البلورة. تم تحديد منحنيات توزيع الطاقة EDC المطابقة لعصابة تكافؤ البلورة من أجل طاقة إشعاع hv=60 eV. من أجل طاقة ارتباط 63.2eV وجدت المساهمة الرئيسية لإلكترونات Co3d في القمة الرئيسية عند طاقة7.46 eV تحت سوية فرمي، في حين لوحظت مساهمة إلكترونات Tb4f عند طاقة 12.08eV تحت سوية فرمي. كما بينت النتائج أن كثافة السويات بقرب سوية فرمي تأخذ صفة التهجين Co3d/O2p، وبدون أي مساهمة من Tb4f.Resonant photoemission of single crystals of the perovskite TbBaCoO3 has been carried out for freshly scraped surfaces. The resonance onset energy at the Co3p→3d threshold is used to explore the contribution of Co3d electrons to the electronic structure of the valence band. The Energy Distribution Curves (EDC) corresponding to the valence band of the crystal were determined for radiation energies hv in the region of hv=60 eV. For 63.2 eV binding energy, the main contribution of Co 3d electrons was found in the main valence band peak located at 7.46 eV below the Fermi level, whereas the contribution of Tb4f electrons was found at energy 12.08 eV below the Fermi level. The results show that the density of states close to the Fermi energy is of Co3d/O2p character, with any Tb4f contribution.

قدمنا في هذا العمل نموذجاً نظرياً لدراسة اهتزازات جملة كمومية بسويتي طاقة مفترضين وجود تفاعل متبادل بينهما من خلال: أولاً: تمثيل الجملة الكمومية ذات سويتي الطاقة بحفرتي كمون كموميتين لانهائيتين متآثرتين على بعد واحد x ومتناظرتين بالنسبة لمبدأ الإحداثيات o، ثمّ إيجاد المتجهات الخاصة والقيم الخاصة لهما باستخدام معادلة شرودنغر المستقرّة Stationary Schrödinger’s equation. ثانياً: إثبات أنّ التقريب غير الاضطرابي كاف لكتابة مؤثر الهاملتوني لهذه الجملة، ولاشتقاق معادلة رابي للجملة Rabi’s equation، وتطبيقها مباشرة على مؤثر التطور للحالة الابتدائية للجملة.We present a theoretical model for studying the oscillations among two-level quantum system when an interaction term is considered: First, we present the two-level quantum system with a symmetric double square potential well in interaction, in one dimension x, then we find the eigenvectors and the eigenvalues for this system by solving the stationary Schrödinger’s equation. Second, we proved that a nonperturbative approach can be conveniently used to write the Hamiltonian operator and to derive the Rabi’s equation for this system, directly applying the time evolution operator to the initial state of the system.

تمت دراسة مزيج من الجراثيم المرجعة للكبريتات (Desulfotomaculum, Desulfovibro ,(Desulfotomonas من أجل التحول الحيوي للفوسفوجيبسوم المدروس. وتبين أنه يمكن إذابة الفوسفوجيبسوم (مقدرة غ/ل) في أوساط ذات مصادر مختلفة للكربون تحتوي اللاكتات (3.65/ل), كحول (2.9غ/ل), كازئين (2.8غ/ل), كانت نسبة الإذابة أقل في الوسط المحتوي الغلوكوز (2.1غ/ل), وأقل بثلاث مرات تقريباً في الوسط الذي يحتوي خلات الصوديوم (1.35/ل). تم حساب التحول الحيوي للفوسفوجيبسوم على أساس كبريت الهيدروجين المنطلق في الوسط, والذي سجل أعظم قيمة له في الوسط المزود بالكحول حيث بلغت (1.29/ل). كما وجد أن الجراثيم المعزولة فعالة جداً في إرجاع الكبريتات من الفوسفوجيبسوم في الوسط المزود بالكحول (2.15غ/ل), وتخفيض (98.03%) من الاحتياج الكيميائي للأكسجين في الوسط المزود بالغلوكوز, وأكبر كمية ذائبة للفوسفوجيبسوم أزيلت في الوسط المزود باللاكتات ثم الكحول فالكازئين كمصدر للكربون. Mixture of sulphate-reducing bacteria (SRB) (Desulfotomaculum, Desulfovibro, Desulfotomonas) were studied for the biotransformation of phosphogypsum. This study shows that the greatest reduction of phosphogypsum (g/l) was possible among different cultures of carbon containing lactate (3.65), ethanol (2.9), casein (2.8); the melting rate was lower in the medium containing glucose (2.1), and three fold less in the medium with sodium acetate(1.35) almost. The biotransformation of phosphogypsum, was calculated on the basis of amount of hydrogen sulphide in cultures. In the studied cultures the greatest amount of hydrogen sulphide was produced from medium containing alcohol (1.29g/l). These isolated bacteria were found to be very effective in the reduction of (2.15 g/l) sulfate from phosphogypsum, with (98.03 %) reduction of Chemical Oxygen Demand in medium with glucose. The greatest amount of dissolved phosphogypsum was removed from medium containing Lactate, ethanol, casein respectively as sources of carbon.

تهدف هذه الدراسة إلى توصيف الظروف التشغيلية لمرشح الفحم الفعال المحضر من قشر الجوز والمنشط كيميائياً بكلوريد الزنك والمفحم عند الدرجة 600Cوذلك بالاعتماد على منحنيات الاختراق. طبقت فرضية انتقال الكتلة (MTZ) بهدف الحصول على تصميم تشغيلي للامتزاز على السرير الثابت والتي تساعد على تحديد متغيرات التشغيل على هذا السرير وذلك عند ثلاثة تراكيز ابتدائية للفينول 20, 40, 60ppm)). درست المتغيرات التشغيلية لعمود الامتزاز بحساب السعة الجزئية لمنطقة انتقال الكتلة F)) وارتفاع منطقة انتقال الكتلة Hz كذلك تم حساب عدد مكافئات الانتقال Nz والكمية الفعلية للفينول التي أزيلت على سرير ثابت من الكربون الفعال عند لحظة الاختراق ABP. The objective of the present work is to determine the operating conditions of an activated carbon filter, based on the characteristics of breakthrough curves. In order to properly design and operate fixed-bed adsorption processes, we apply the concept of the mass transfer zone (MTZ) that helps to obtain the evolutions of the operating parameters of the fixed-bed. Activated carbon is prepared from walnuts crust and activated by impregnating in aqueous zinc chloride solution of wt %(40). Phenol solutions were prepared in three initial concentrations of phenol (20, 40, 60 ppm). The experimental data were analyzed by calculating fractional capacity (F), the height of (MTZ) (HZ), the number of unit transfer equivalent (NZ), the amount of phenol eliminated by the bed of activated carbon at the breakthrough (ABP). The results of the study show that granular sizes (C, D) were more effective than (A, B).

تم عزل جراثيم عائدة لنوع المتقلبة الشائعةProteus volgaris من المياه الشاطئية لمدينة اللاذقية (المرفأ) الملوثة بالمواد النفطية الناتجة عن نشاط النقل البحري، واختبرت مقدرتها على تفكيك الألكانات النفطية الملوثة لهذه البيئة مخبرياً باستخدام تراكيز مختلفة من الملوثات النفطية. واستخدمت تقانة الكروماتوغرافيا الغازية (GC) لقياس تراكيز الألكانات النفطية. بينت النتائج أن الجراثيم المعزولة قادرة على تفكيك السلاسل الألكانية المختلفة، حيث كانت نسبة تفكيك كل من C12، C16، C18 هي 96.7%، 78.59%، 97.27 % على التوالي، بينما بلغت نسبة التفكك الاجمالي للسلاسل الألكانية 77.14% عند إضافة 10 ملغ/مل من الملوثات النفطية, بينما لم تتجاوز نسبة التفكك 17.26 % عند إضافة 75 ملغ/مل منها. وبالتالي فإن القدرة العالية لجراثيمProteus volgaris على تفكيك السلاسل الألكانية الطويلة يؤهلها لتكون فاعلة في عملية المعالجة الحيوية Bioremediation للبيئة البحرية الملوثة.Proteus volgaris was isolated from costal sea water of Lattakia city port, as it is contaminated with petroleum compositions coming from marine transportations activities. The ability of this bacteria to degrade the petroleum alkanes was studied by using different concentrations of petroleum as sole source of carbon and energy. The gas chromatography (GC) technique was used to measure the concentration of alkanes. Results showed that the isolated bacteria were able to degrade different alkanes chains. The ratio of biodegradation of C12, C16, C18 were 96.75%, 78.59%, 97.27% respectively, while the rate of biodegradation of the entire amount of alkanes was 77.14% in 10 mg/ml polluting concentration. The percentage of biodegradation at concentration 75 mg/ml of petroleum was 17.26%. Therefore, the high ability of Proteus volgaris to degrade the long chains alkanes recommended it to be effective in the bioremediation process of the contaminated marine environments.

تكمن القيمة العلمية والعملية لهذا البحث في التعرف على مواصفات الترب الغضارية الموجودة في منطقة النبك, وإمكانية استخدامها في إنشاء سد الوغر التجميعي. وقد تمت الدراسة على خمس عينات تم اختيارها من مقلع حفر الملاجئ الغضاري الذي سيستخدم في انشاء سد الوغر التجميعي, تم من خلالها تحديد بعض المواصفات الجيوهندسية لهذه الترب وأهمها (حد السيولة – حد اللدانة – دليل اللدانة - دليل القوام والسيولة – فعالية الغضار – درجة الانهياريه). وبالاعتماد على نتائج هذه الدراسة استخدمنا التصنيفات العالمية ( تصنيف كازاغراندي – نظام التصنيف الموحد – التصنيف الأمريكي والروسي حسب دليل اللدانة ) لدراسة ترب المنطقة المراد دراستها. واعتمدنا نتائج الدراسة لتحديد موقع هذه الترب وفقا للتصنيف العالمي, واقترحنا بعض الحلول المناسبة لتحسين خواص الترب المستخدمة في تشييد السدود الترابية. The scientific and practical value of this research appears in recognizing the characteristics of the clay soil, which is located in Alnabeck, and used in constructing ALwagar earth fill dam. We will study five samples chosen from the materials site Hofar ALmlagea and which will be used in constructing ALwagar earth fill dam through which some Geo-geometrical characteristics like (Liquid Limit, Plasticity Limit, plasticity index, Consistency Index, Liquidity Index, Clay activity, collapse degree) will be determined. Depending on the Results of this study, we used international classifications (Casagrande classification – Unified Soil Classification System) to study the soil of the studied area. We made use of the results of the experimental study to determine the position of soil according to the international classification, and we suggested some solutions to improve the characteristics of the soil which is used in constructing soil dams.

Theses fuzzy parameters are characterized by fuzzy numbers. For such problems, the concept of a-Pareto optimality introduced by extending the ordinary Pareto optimality based on the a-level sets of fuzzy numbers. The proposed solution method is based on cutting planes, which are based on local tradeoff ratios between the objective functions as prescribed by the decision maker at each iterate generated by the method. An illustrative numerical example is given to clarity this method.

تم، في هذا العمل، تسجيل عدد جسيمات ألفا الصادرة عن منبع من الأمريسيوم-241، والمتبعثرة على وريقات رقيقة من الذهب والألمنيوم بتابعية زاوية التبعثر q (0o – 30o)، باستخدام كاشف نصف ناقل وغرفة تبعثر رذرفورد. تم أيضاً قياس المقطع العرضي التفاضلي عن الناتج عن هذا التبعثر، وحساب العدد الذري للهدف تجريبياً، لكل من الذهب والألمنيوم. مقارنة النتائج التجريبية بالنتائج النظرية يشير إلى تطابق جيد بينهما.In this work, it has been recording the alpha particles emitted from an Amerecium-241 source, and scattered by a gold and Aluminum thin foils as a function of the scattering angle q (0o-30o), using a semiconductor detector and Rutherford scattering chamber. It always has been measuring the differential cross section resulting from this scattering, and experimentally determining the atomic number of Gold and Aluminum. Comparison between experimental and theoretical results shows a good agreement.

تم في هذا البحث تقديم طريقة عددية لحل مسألة الأمثليات غير المقيدة. تعتمد الطريقة على إنشاء قاعدة من المتجهات المترافقة، ثم تحديثها تكراريا بادخال متجهات تدرج مترافقة تحقق شرط الانحدار الأشد وشروط وولف-باول. اختُبِرتْ الطريقة بحل مجموعة من مسائل الاختبار القياسية الموجودة في دراسات سابقة. تبين النتائج العددية أن الطريقة المقترحة تستطيع إيجاد الحل العددي المضبوط من أجل الدوال التربيعية، وتستطيع أيضا تقديم حلول عددية عالية الدقة إذا كانت دالة الهدف فوق تربيعية. وبمقارنة النتائج التي تم التوصل إليها مع نتائج الطرائق الأخرى تظهر الكفاءة والفعالية التطبيقية للطريقة المقترحة.In this paper, we present numerical method for solving unconstrained optimization problems. The method is based on a set of conjugate search directions, and then this set is updated repeatedly by generating new conjugate gradient directions so that steepest descent condition and Wolfe- Powell conditions are satisfied. The method is tested on set of standard problems. Numerical experiments show that the proposed method can find exact solution for quadratic functions, so it can find high accurate solution for over quadratic functions. Moreover, the comparisons with other available results illustrate the applicability and efficiency of the presented method.

تركزت الدراسة على تحديد أهم الخصائص الهيدروكيميائية لمياه منطقة مصب نهر السن عبر تحديد تركيز الشوارد المغذية (النترات والنتريت والأمونيوم والفوسفات والسيليكات) والعوامل المؤثرة عليها، فضلاً على تحديد الكلوروفيل aفي عينات مائية جمعت من عدة مواقع من منطقة مصب نهر السن خلال الفترة الممتدة بين آذار 2011 وشباط 2012. رصدت أعلى التراكيز للشوارد المغذية على مدار العام في نقطة المصب S0 وتقاربت مع تركيز الشوارد المغذية في المحطة S50 على مدار أشهر العام بسبب جغرافية منطقة مصب نهر السن، كما تناقص تركيز الشوارد المغذية مع الابتعاد عن نقطة المصب متوافقاً مع تدرج الملوحة خلال جميع الطلعات البحرية، إذ شكّلت نقطة المصب المصدر الرئيس للمغذيات التي يتم توزيعها إلى باقي المحطات. أبدت تراكيز الشوارد المغذية تدرجاً واضحاً خلال أشهر الشتاء امتد إلى بعد 3000 متر عن نقطة المصب، بينما امتازت أشهر الصيف بتدرج أقل امتداداً في تركيز الشوارد المغذية، إذ انحصرت منطقة التدرج ضمن - 200 500 متر الأولى. أظهرت الدراسة الإحصائية وجود علاقة معنوية عكسية بين تركيز المغذيات وملوحة المياه، كما ارتبطت المغذيات إيجابياً فيما بينها، إذ أظهرت النترات علاقة ارتباط معنوية مع الفوسفات والسيليكات، بينما كانت علاقة ارتباط النترات مع النتريت وارتباط الأمونيوم مع النتريت معنوية ولكنها أقل أهمية.The study, has Focused on determination of the most important hydrochemical characteristics of AL-sin estuary area via determining the concentration of nutrient ions (nitrate, nitrite, ammonia, phosphates and silicates) and the factors affecting them. In addition, determining chlorophyll a in water samples collected from several locations of that area during the period between March 2011 and February 2012 was done. The highest concentrations of nutrient throughout the year were reported at river estuary point (S0) and converged with nutrient concentrations in the station S50 because of the geographic nature of AL-sin estuary area. A depression in their concentrations was observed in the station distanced away from the river estuary point, compatible with salinity gradient. River estuary point (S0) formed the main source of nutrients that are distributed to the rest of the stations. Nutrient concentrations showed clear gradual depression during the winter months down to 3,000 meters from the estuary point, while the gradient in the summer months has less extension; It was within the first 200 - 500 meters. Statistical study revealed a significant negative relationship between the nutrient concentrations and water salinity and positive relationship between each other. The nitrate showed a significant correlation with phosphate and silicate, while the correlation between nitrite and nitrate and the correlation between nitrite and ammonia were significant but less important.

تناول هذا البحث دراسة توزع ومصادر الفحوم الهيدروجينية العطرية متعددة الحلقات ( (PAHs في عينات مائية ورسوبية جمعت فصلياً من عشرة مواقع مختلفة من شاطئ مدينة طرطوس خلال العام 2010. تأثر تركيز مركبات الـ PAHs في العينات المائية للمواقع المدروسة بالتغيرات الفصلية وبمصادر التلوث الناجمة عن محطات الصرف الصحي. تراوحت التراكيز الإجمالية بين (147.14 – 6.97) ng/l مع سيطرة مركبات PAHs ذات الأصل البترولي و الحاوية على ثلاث حلقات و في معظم المحطات المدروسة. تميزت العينات الرسوبية بتراكيزمنخفضة لمركبات الـ PAHs مقارنة مع العينات المائية نتيجة عدم حدوث عمليات ترسيب فعالة. تراوحت التراكيز الإجمالية لمركبات PAHs بين 55.28 – 1.76) ng/g dw) مع سيطرة لمركبات الـPAHs ذات الأصل البترولي و الحاوية على ثلاث حلقات في الربيع والخريف, بالمقابل سادت مركبات PAHs ذات الأصل الحراري والحاوية على أربع حلقات في عينات الخريف.The distribution and sources of 14 compounds of Polycyclic Aromatic Hydrocarbons (PAHs) in marine water and sediment samples were studied. These samples were collected seasonally from 10 different locations of Tartous city (Syria) during the period Apr. – Nov. 2010. The concentrations of PAHs in the water samples of the study areas were affected by location and sources of pollution resulted from the domestic waste-water discharge. The total concentration of PAHs ranged from 6.97 to 147.1 ng/l and the petrogenic PAHs compounds containing 3 rings dominated the most sites. The sediment samples were characterized by the low concentrations of PAHs compared to the respective concentrations in the water samples due to the absence of effective depositional processes. The total concentration of PAHs ranged from 1.76 to 55.28 ng/g dw. The petrogenic PAHs compounds containing 3 rings were dominant in the spring and summer, while the pyrogenic PAHs compounds containing 4 rings were dominant in the autumn.

جمعت العينات من منتجات غذائية مختلفة ولعدة مرات في كل موسم ولمدة سنتين من اجل التعيين الكمي لحمض الفيتيك وقياس تركيزه في المنتجات المصنعة ودراسة تأثير العمليات التكنولوجية في التخلص من هذا المركب والتقليل من تأثيراته الصحية. بينت الدراسة بأن أغلب المنتجات المدروسة والمستهلكة في مدينة اللاذقية, تحتوي على مستويات عالية من حمض الفيتيك ولاسيما المنتجات غير الناضجة منها(0.15-3.57 غ%غ.م.ج) ومشتقاتها (0-1.95 غ%غ.م.ج), وأن تطبيق بعض المعالجات التكنولوجية على بعض الأغذية تخفض بين (20-60)% من المحتوى في حمض الفيتيك.

تعد المياه الجوفية مصدراً رئيساً للمياه المتاحة للاستعمال في المناطق الجافة وشبه الجافة، لذلك لابد من حماية نوعيتها، حيث تملك بيانات التوزع المكاني والزماني أهمية كبيرة. وتعد الطرائق الجيوإحصائية واحدة من أكثر التقنيات المتقدمة من أجل التنبؤ بنوعية المياه. استُخدمت طريقتا Kriging و IDW من أجل التنبؤ المكاني للنترات NO3- في المياه الجوفية. وأخذت البيانات من 21 بئراً موزعة في غوطة دمشق الشرقية. وبعد جدولة البيانات، تم رسم مخطط التغير. واستخدمت القيمة الأقل لـ RSS، وبناءً عليه وجد أن النموذج الكروي هو النموذج الأفضل. وتم تحديد الطريقة الأفضل للتنبؤ بناءً على cross-validation وقيمة RMSE. تظهر النتائج بأن طريقة Kriging هي الأفضل والأدق مقارنةً مع طريقة IDW. وتوجد تبعية مكانية كبيرة لمتغير النترات، تبلغ 2.2 %. ثم تمّ إعداد خرائط توزع النترات بطريقة Kriging، وتحديد مدى صلاحية المياه الجوفية للشرب والري، إضافةً إلى خريطة الاحتمالية للنترات عند العتبة الحدية 50 ملغ/ل.

Monodispersed CdSe nanoparticles with sufficient luminescence intensity have been prepared by chemical method in solution phase, and in two forms: CdSe as a core covered by Olic acide as an organic capping agent, while the second form is CdSe as a core covered by a layer of CdS (CdSe/CdS core shell). The nanodots size obtained directly from high resolution transmission electron microscopy (TEM) and absorption peaks using Paul Mulvaneys formula are in good agreement. The optical properties and the luminescence intensity as a function of CdSe concentration and the type of solvent have been investigated. The intensity of photoluminescence peak decreases and the peak shifts toward the blue energy side as the concentration reduced. تم في هذا العمل تحضير عينات سيانيد الكادميوم النانومترية (S CdSe NC) بطريقة كيميائية ضمن محاليلها الغروية وذلك بشكلين مختلفين بغية تحسين تألقها: الأول من خلال تغطية سطح بلورة CdSe بوساطة جزيئات عضوية (organic capping agent) مثل ((OA) Olic acide,). أما الشكل الأخر فيغطى بطبقة من مركب كبريت الكادميوم /Shell) CdS CdSe/CdS (core. تم تسجيل أطياف الإمتصاص والإصدار لهذه العينات ضمن مذيبات متنوعة وبتراكيز مختلفة. تم حساب حجم هذه العينات بطريقتين. الأولى مباشرة من صورة المجهر الإلكتروني عالية الدقة, أما الثانية فتعتمد على حساب نصف قطر العينة مستخدمين علاقة Paul Mulvaneys. أعطت الطريقتان قياساً متطابقاً بتقريب مقبول. تم أيضاً قياس شدة التألق الناتج عن جزيئات CdSe بالإضافة لطاقة قمة طيف الإصدار عند تراكيز معينة. وقد لاحظنا تناقصاً لشدة التألق، وانزياحاً لقمة طيف التألق نحو الطاقات الأعلى عند تناقص تركيز هذه البلورات. بيّن تحليل النتائج التجريبية أن شدة الإصدار ترتبط مباشرة بقطبية المذيب و تأثيرها في سطوح هذه المواد، بتناقص عدد جزيئات CdSe النانوية عند إنقاص التركيز.

يتضمن هذا البحث مناقشة طريقة تعيين البارامترات الهيدروجيولوجية باستخدام معطيات مراقبة نظام المياه الجوفية، وذلك بغية تحديد قيم هذه المعاملات على مساحات كبيرة. والتي تملك أهمية تطبيقية كبيرة وخاصةً عند نمذجة المسائل الهيدروجيولوجية حيث تسمح بإيضاح وتدقيق البنية الهيدروجيولوجية والهيدروديناميكية للمنطقة وأسباب تغير الخواص الرشحية للطبقة الحاملة للمياه وغيرها. وقد تبين من خلال هذه الدراسة أن الناقلية المائية تتغير من 36 إلى 570 م2/يوم، وعامل الرشح من 1 إلى 53 م/يوم، وكانت قيم المعطائية المائية منخفضة إلى متوسطة حيث تأرجحت بين 0.00004 و 0.2 بسبب ازدياد عامل الانتشار، في حين تراوحت التغذية الراشحة من 1 - 40 % من الهطولات تقريباً. إن النتائج التي تمّ الحصول عليها تتوافق توافقاً جيداً مع الخصائص الجيولوجية ـ البنيوية والليتولوجية ـ السحنية لمنطقة الدراسة. This research discusses the way of defining hydogeological parameters by using monitored data of the ground water system, for defining the values of these coefficients on large areas, which has a practical significance especially in modeling the hydrogeological problems which allows explaining and checking the hydrodynamic and the hydrogeological structures of the area and the reasons of changing the filteration properties of the aquifer. It appears that transmissivity varied from 36 to 570 m2/day, the permeability from 1 to 53 m/day, and the water yield from low to medium between 0.00004 and 0.2 because of the rising of the coefficient of diffusion. The filtration recharge approximately from 1 - 40% from the rain falls. The obtained results are in good conformity with the geological characteristics - structural and litologic - facies characteristics for the study area.

In this paper, spline collocation method is considered for solving two forms of problems. The first form is general linear sixth-order boundary-value problem (BVP), and the second form is nonlinear sixth-order initial value problem (IVP). The existence, uniqueness, error estimation and convergence analysis of purpose methods are investigated. The study shows that proposed spline method with three collocation points can find the spline solutions and their derivatives up to sixth-order of the two BVP and IVP, thus is very effective tools in numerically solving such problems. Several examples are given to verify the reliability and efficiency of the proposed method. Comparisons are made to reconfirm the efficiency and accuracy of the suggested techniques.في هذا العمل تم تقديم طريقة الشريحة التجميعية للحل العددي لنوعين من المسائل. النوع الأول هو مسألة القيمة الحدية في المعادلات التفاضلية الخطية المعممة من المرتبة السادسة و النوع الثاني هو مسألة القيمة الابتدائية في المعادلات التفاضلية غير الخطية المعممة من المرتبة السادسة. تم إثبات أن الطريقة المذكورة عند تطبيقها لمثل هذه المسائل تكون موجودة بشكل وحيد بالإضافة إلى تقدير الأخطاء وتحليل التقارب. تبين الدراسة أن طريقة الشريحة بثلاث نقاط تجميعية تستطيع إيجاد الحلول العددية الشرائحية ومشتقاتها حتى المرتبة السادسة للمسائل الخطية وغير الخطية المطروحة وبالتالي فهي أداة فعالة للحل العددي لمثل هذه المسائل. تم إثبات فعالية وكفاءة الطريقة المقترحة بحل عدد من مسائل الاختبار ومقارنة النتائج التي تم التوصل إليها مع نتائج لطرائق أخرى.

أعطت نتائج البحث الذي اعتمد على التحريات الهدروجيولوجية و التكتونية،المرتبطة بمصادر المياه العذبة في حوض السن، أن الحامل الأساس للمياه الجوفية في حوض السن يعود بشكل رئيسٍإلى الحامل المائي الجوراسي.يعتمد الحوض الصباب لنبع السن على التغذية الراشحة لمياه الأمطار و الثلوج عبر التشكيلات الجوراسية من المنطقة الشمالية والشمالية الشرقية للحوض.إن اتجاه حركة المياه الجوفية لهذا الحامل يكون نحو الغرب و الجنوب الغربي، حيث منطقة التصريف في نبع السن و الينابيع تحت البحرية قبالة الشاطئ. بينت الدراسة التكتونية وجود مجموعاتمن الشقوق و الفوالق ذات الاتجاهات NE-SW وENE-WSW و NW-SE.تتوافق حركة المياه الجوفية مع اتجاهات مجموعات الشقوق و الفوالق NE-SW و ENE-WSWو بنية فالق السن الذي يسمح بوجود علاقة تفاعلية بين الحامل المائي الرئيسي الجوراسي و بقية الحوامل الثانوية و خصوصا السينوماني.The obtained results by hydrogeological and Tectonic survey related to fresh water resources in Al-Sin Basin, indicated that the fundamental aquifer of underground water in AL-SIN region belong to Jurassic. The alimentary basin of Al-Sin spring depend upon filtration of rainfall water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation is toward west and south-west where we find flow place of Al-Sin spring and submarine fresh springs near seashore. Tectonical study shows the existence of fractures and fault groups with NE-SW, ENE-WSW and NW-SE directions. Groundwater movement has the same direction of fractures and faults NE-SW to ENE-WSW and Al-Sin fault structure which allow the existence of direct relation between principal Jurassic aquifer and secondary aquifer especially Cenomanian one.

يهدف هذا البحث إلى دراسة تأثير بعض الشروط التحليلية في تحديد الزرنيخ في الأوساط المائية بطريقة المعايرة الكمونية ومن ثم اختيارها بوصفها شروطاً مثلى معتمدة لهذا التحديد. تمت دراسة تأثير كل من(قيمةPH الوسط ، نوع وتركيز المحلول الموقي ، تأثير الشوارد المعيقة) على تحديد الزرنيخ في الأوساط المائية بالمعايرة الكمونية وذلك باستخدام محلول قياسي من اليود. كما تم العمل على رفع حساسية الطريقة والوصول بحد الكشف إلى مرتبة ppm. إذ تجدر الإشارة إلى أنّ هناك شروطاً hWتقنية يجب ضبطها لتحديد القيمة الفعلية لنقطة نهاية المعايرة ومعالجة البيانات الخاصة بسحاحة المحلول القياسي (السرعة الأولية والتباطؤ بالقرب من نقطة نهاية المعايرة). أظهرت الدراسة أن قيمة الـPH المناسبة للمعايرة الكمونية للزرنيخ باليود تترواح بين(PH:8-9)،كما تبين أن الاستجابة العملية للزرنيخ على مسرى البلاتين كانت سريعة عند استخدام Na2SO4 بوصفه محلولاً موقياً بتركيز0.1M والتي استخدمت بنجاح للتحديد الكمي للزرنيخ As3+ بحد كشف يصل إلى2×10-6 mol/l. كما تبين خلال الدراسة عدم إمكانية تحديد الزرنيخ بوجود شوارد النحاس في المحلول، في حين لا تؤثر وجود شوارد الرصاص والكبريتات والكلوريد. This research aims to study the effect of certain analytical conditions to determine the arsenic in aqueous media using a Potentiometric, and then choose and adopt the optimum conditions for this determinism. We studied the effect of each of the (PH value, type, concentration puffer, effect of crippling electrolytes) to determine the arsenic in aqueous media and calibration using a standard solution of iodine. We also worked on raising the sensitivity of the method detection limit access to the ppm. It should be noted that technical conditions must be tuned to determine the actual value of the end point calibration and data processing of standard solution (initial velocity and deceleration near the end point calibration). The study showed that the PH value appropriate for calibration of arsenic with iodine (8-9), also found that the response process of arsenic on the electrode platinum has been excellent when using Na2SO4 as puffer with concentration of 0.1 M, which has been successfully used to quantify arsenic As+3 up to detect up to 2 × 10-6M. As it turns out during the study, it was not possible to determine the arsenic presence of copper ions in the solution, while the presence of lead and sulfate ions and chloride was not affective.

حضرت مجموعة من العينات بتحميل أيونات الكبريتات على الخام الطبيعي السوري، بطريقة نقع عينات الخام بعد غسلها وتجفيفها في محلول مائي لكبريتات الأمونيوم مختلف التركيز، مع التحريك المستمر، وتركت لتجفّ في درجة حرارة الغرفة, ثم جففت العينات عند الدرجة 1100C وكلست عند الدرجة 6000C. درست خواص العينات الناتجة باستخدام طرائق الأشعة السينية X.R.D،الأشعة تحت الحمراء FTIR, التحليل الحراري الوزني التفاضلي TG-DTAوقياس المساحة السطحية النوعية. وجد أن عملية التحميل تؤدي إلى اختلاف في بنية العينات،إذ يظهر طور جديد من كبريتات العناصر الموجودة في بنية العينات الخام, وارتباطات ثنائية السن لأيونات SO42- مع بعض العناصر المعدنية. تزداد الفعالية الحفزية للمحفز المحضر في تفاعل تكسير البولي إيثلين ازدياداً واضحاً، مع اختلاف في انتقائية المركبات الناتجة عن التفاعل. Sulfated ions loaded on natural Syrian zeolite were prepared by impregnation method of zeolite samples in aqueous solution of ammonium sulfate with different concentrations. After that, the samples were dried at 1100C Followed by calcinations at 6000C. The Characterization tests have been done of prepared catalysts using X.R.D, FTIR, TG-DTA methods and by measurement of surface aria. A new phase of sulfated elements has been formed as a result of binding SO42- ions as sulfated complex coordinated with metal elements. The catalytic activity of sample in polyethylene cracking reaction was increased directly with the percent of sulfate ions

In this paper we present the structural, optical and electrical characteristics of ZnO thin films grown for different parameters by the atomic layer deposition (ALD) method. The films were grown on glass and silicon substrates at low temperatures. We used diethyl-zinc (DEZn) and deionized water as zinc and an oxygen sources, respectively. Measurements of surface morphology, photoluminescence at room temperature (RT PL) and Hall Effect were made for ZnO layers. The films obtained at 130°C show the highest carrier concentration (1.1×1019 cm-3) and the lowest resistivity (2.84×10-2 Wcm). The films exhibit mobility up to 19.98 cm2/Vs that we associate to the technological process used. نقدم في هذه الورقة الخصائص البنيوية والضوئية والكهربائية لأفلام رقيقة من أكسيد الزنك تمت تنميتها من أجل بارامترات مختلفة بوساطة طريقة الترسيب الذري الطبقي (ALD) . وقد نميت هذه الأفلام على ركائز من الزجاج والسيلكون عند درجات حرارة منخفضة. استخدمنا ثنائي إيتيل الزنك(diethyl-zinc) والماء منزوع الأيونات كمصادر للزنك والأكسجين، على التوالي. أجريت قياسات مورفولوجيا السطح، والتألق الضوئي في درجة حرارة الغرفة ومفعول هول لطبقات من أكسيد الزنك. وقد بينت الدراسة أن الأفلام التي تم الحصول عليها عند درجة حرارة130°C تظهر أعلى تركيز للحاملات(1.1×1019 cm-3) وأقل مقاومة(2.84×10-2 Wcm) . كما أظهرت الأفلام حركية تصل إلى 19.98 cm2/Vs وأنها ترتبط مع عملية التكنولوجيا المستخدمة.

The possibility of using tuff and modified Jordanian naturalzeolite to remove the iron ions, a model component of heavy metals in underground water, off aqueous solution were studied. Bench-scale process was used to remove the iron ions off standard solutions and real under ground water. Different parameters affected the ion exchange have been investigated, such as concentration, modifier type and PH. Zeolite characterizations weredetermined as XRD, XRF, BET, TGA, andFTIRmethods.We found that the modified zeolite with sodium chloride had more effect than other salts and the iron ions exchange efficiency depends on concentration.Zeolite efficiency was affected by PH value. Time of sorption equilibrium achieved within 250 min. The results agree with Langmuir model.درست امكانية استخدام الزيولايت الطبيعي الأردني الخام والمعدل لإزالة ايونات الحديد من المحاليل المائية والذي يمثل احد المعادن الثقيلةالموجودة احيانا في المياه العذبة الجوفيه. حيث تم استخدام الفلتره الثابتة لأجراء تجارب ازالة ايونات الحديد المحضر في محاليل معياريه وكذلك الموجود في مياه جوفيه حقيقتيه. درس تأثير بعض المتحولات على عملية التبادل الأيوني مثل: التركيز , الماده المستخدمه في التعديل ودرجة حموضة المياه (PH) وقد تم استخدام الزيولايت الصناعي (A 4ِ)للمقارنة . حددت مواصفات الزيولايتألمستخدمتحديد المساحه السطحييه النوعيه وفق طريقةBET, وبواسطة بعض الطرائق الأخرى مثل : .XRD , XRF, TGA ,FTIR وجد ان الزيولايت المعدل بكلوريد الصوديوم هو الأكثر فعاليه مقارنه بالأملاح الأخرىوان كفاءة التبادل الأيوني لأيون ألحديد تعتمد على التركيز, كما وجد ان قيمة PHتؤثر بشكل واضح على فعالية الزيولايت.لقد كان زمن الاتزان الكيميائي بعد 250 دقيقه ووجد ان النتائج تتطابق مع نموذج لانغمير (Langmuir). الكلمات المفتاحيه: التف الزيولاتي الأردني(الفلبسايت), المعادن الثقيله, التبادل الأيوني, نموذج لانغمير, توصيف الزيولايت.

يتضمن هذا البحث دراسة هيدروجيوكيميائية لبعض آبار المياه الجوفية المختارة من المنطقة الواقعة بين نهري الصنوبر والكبير الشمالي بهدف تحديد نوعية مياهها ومنشأ هذه المياه من أجل التخطيط المستقبلي الأمثل لاستعمالات الموارد المائية في هذه المنطقة. وقد تبين من خلال هذه الدراسة وجود نمطين هيدروكيميائيين أساسيين: الأول هيدروكربوناتي ـــــــ مغنيزي، كلسي، صودي للمياه، والثاني سولفاتي ـــــــ كلسي، مغنيزي، صودي، وهذه الأنماط الجيوكيميائية تشير إلى وجود عدد من الأملاح في المياه الجوفية تمّ حسابها إذ تبين تشكل ملحي كبريتات الصوديوم وهيدروكربونات الصوديوم واللذين يشيران إلى المنشأ الجوي الراشح للمياه (عميق وسطحي)، وملح كلور المغنيزيوم الذي يشير إلى المنشأ البحري، وأن المياه في كافة الآبار صالحة لأغراض الري.This research includes a Hydrogeochemical study of specific ground water wells between AL-Snobar and AL-Kabir AL-Shimali Rivers. This aims at specifying water quality and origion in order to plan the optimum future ways of using water supplies in the region. This study finds out two main hydrochemical types: a hydrocarbon type of water having a high content of magnesium, lime or sodium, and a sulpharic type of water having a high content of lime, magnesium or sodium. These two geochemical types show that a number of minerals can be found in groundwater such as Na2SO4 and NaHCO3 which indicates the air origin of filtrated water, and MgCl2 which indicates the sea origin. In addition, it indicates that groundwater in all wells can be used for irrigation.
