Item غلاف العدد 44-2(2018-01-15)Item Simultaneous Spectrophotometric Determination of Iron and Cobalt by H-Point Standard Addition Method(كلية الدراسات العليا جامعة النيلين, 2018-07-15) M. AL Hassan, Tahani.; A-Z. Eltayeb, M.Iron is always found in association with cobalt in many samples, both natural and artificial. The H-point standard addition method (HPSAM) was applied for the simultaneous spectrophotometric determination of Fe(II) and Co(II) was carried out as Pan-complexes. Beer's law was obeyed at 473 nm for Fe(II) and 592 nm for Co(II) in the concentration range 5.0E-6 to 5.0E-5 mg/L, using 1-(2-pyridylazo)-2 naphthol (PAN) as chromogenic reagent and at pH 5.8Item تطوير نموذج لتشخيص الخطط العلاجية لمرضى السكرى باستخدام تنقيب البيانات(كلية الدراسات العليا جامعة النيلين, 2018-07-15) محمد حسن احمد, ناهد; عبد الكريم عبد الفضيل, طارقوجود كميات كبيرة من البيانات عن الامراض المزمنة أدى الى الحوجة الملحة للاستفادة من التقنيات الحديثة لتنظيم هذه البيانات وتحويلها الى معلومات مفيدة يمكن الاستفادة منهاItem تأثير برنامج صحي محوسب على معلومات الطلاب الصم حول أنماط الحياة الصحية في ولاية الخرطوم(كلية الدراسات العليا جامعة النيلين, 2018-07-15) محمد أحمد, بسمات; خالد الطعاني, نايفأكثر من 300 مليون انسان في العالم يعانون من الاعاقة السمعية، معظهم مصاب منذ الولادة ويعاني هؤلاء من صعوبة التواصل ومحدودية الوصول إلى المعلومات مقارنة بنظرائهم الطبيعيين.Item Correlation between Jitter and Retransmission Attempts in UMTS and VoIP over WiFi(كلية الدراسات العليا جامعة النيلين, 2018-07-15) Awad Elgamel, Diaeldin; Babiker A. Mustafa, Amin; El-Azhary, IsmailSimulation of VoIP (Voice over Internet Protocol) traffic through UMTS (Universal Mobile Telecommunication System) and WiFi (IEEE 802.11n) Jitter and Retransmission attempts parameters, alone and together are obtained, analyzed and a correlation between the two parameters were discussed. The average jitter is affected by many factors, which lead to non-uniform performance and readings. The conformance of the two parameters was matched for 50 and 70 mobile scenario, while variant readings were found in the 30 mobile scenarios.Item Conflicts and Natural Environment of the Sudan With some emphasis on Darfur Region(2018-07-15) El Siddig Ahmed El Tohami, Abu BakrThis paper is an attempt to highlight the strong link between the misuse of natural resources or resource degradation and conflicts in Sudan and vice versa and find out the impacts of conflicts. Critical review of relevant literature was done to satisfy the above mentioned objectives. Causes of conflicts in Darfur can be summed up as follows:Item Review of the Recycle and Reuse of Waste Plastics(كلية الدراسات العليا جامعة النيلين, 2018-07-15) Islam Salman Ali, Higazi; Karama Abdalla, BabikerPlastic recycling is a very important process to solve the environmental pollution problems and to reduce the cost of plastic manufacture. The paper tacked on the previous studies which were done on plastic recycling from 1994 to 2018 and it explain the most useful way for effect plastic recycling.Item إستخدام تقنيات تنقيب البيانات فى نظم دعم اتخاذ القرار للتنبؤ بالصادرات بالتطبيق على الجمارك السودانية(كلية الدراسات العليا جامعة النيلين, 2018-07-15) عوض محمد على, ياسر; حاج على, عوضتناولت الدراسة استخدام الطرق الاحصائية للتنبؤ بالصادرات الجمركية بالتطبيق علي الجمارك السودانية، كمنت مشكلة الدراسة فى عدم استخدام المؤسسات والهيئات لأنظمة دعم القرار الذي يؤدي إلى ضعف فى القرارات مما ينتج عنه تخطيط غير سليم ،هدفت الدراسة إلى تقديم دراسة تطبيقية فى مجال التنقيب فى البيانات لدعم صانعي القرار بهيئة الجمارك السودانية وذلك للتوصل إلى الطريقة الافضل من بين اربعة طرق احصائية، اعتمدت الدراسة علي المنهج الوصفي و المنهج الاستنباطي.Item Cloud Point Extraction and Pre-concentration for the Determination of Cadmium in Some Water Samples by Flame Atomic Absorption Spectrometry(كلية الدراسات العليا جامعة النيلين, 2018-07-15) E. Babiker, Rehab; A -Z Eltayeb, MohamedA cloud point extraction process using the nonionic surfactant (Triton X – 100) to extract cadmium (II) from aqueous solutions was applied. The method is based on the complexation reaction of Cd(II) with benzil bis(Semicarbazone) (BBSC) as a complexing agent and extraction of the complex formed. The analyte ions are quantitatively extracted to the phase rich in the nonionic surfactant t- octylphenoxy poly ethoxy ethanol (C14H22 O(C2H4O)n following centrifugation. The optimal extraction and reaction conditions were studied, and the analytical characteristics of the method were obtained. Linearity was obeyed in the range of 0.25 – 2.5 µg.ml-1 of Cd(II) ion.Item محتويات العدد الأربع والأربعون- الجزء الثاني يوليو - 2018(كلية الدراسات العليا جامعة النيلين, 2018-07-15) الدراسات العليا, مجلةمجلة علمية محكمة شهرية تصدر عن كلية الدراسات العليا بجامعة النيلينItem Design Integrated System for Sudan Electricity Distribution Company(كلية الدراسات العليا جامعة النيلين, 2018-07-15) فتوح عثمان, سيف الدينMost of the institutes, companies and corporations in the Sudanese market have many systems, but most of those systems are isolated and there is no exchange of information. As an Example of such systems are OpenERP and OpenKM systems which are Implemented in Electricity Company in Sudan, in these systems the user can attach document to OpenERP system and the same document will attach again into OpenKM system and that is not good practice. In this Paper Analytical Description Methodology and open source programs are used by describing and clarifying the Problem and add a middle layer between Two systems without restructuring them. The paper finds that by add middle layer, systems can pass data and perform transactions to each other in less time and cost.Item DESIGIN AND IMPLEMENTATION OF A SELF-STEERED CAR(كلية الدراسات العليا جامعة النيلين, 2018-07-15) Abdallah Ahmed, SaraRecent development of technology serves the needs of humanity.
