Abstract

Our aim in this paper is to study the relationships between min-cs modules and some other known generalizations of cs-modules such as ECS-modules, P-extending modules and n-extending modules. Also we introduce and study the relationships between direct sum of mic-cs modules and mc-injectivity.

في هذا البحث نقوم بدراسة العلاقة بين اصغر مقاسات التوسع و بعض التعميمات الأخرى لمقاسات التوسع مثل مقاسات ال ECS ومقاسات التوسع من النمط P وكذلك مقاسات التوسع من النمط n. وأيضا قدمنا ودرسنا العلاقة بين المجموع المباشر لأصغر مقاسات التوسع والمقاسات الاغمارية من النمط mc.

Abstract

In this paper, we study the direct sum of min (max)-CS modules. We show that the direct sum of min (max)-CS modules need not be min (max)-CS module. So we give many sufficient conditions under which the direct sum of min (max)-CS modules become min (max)-CS module

Abstract

Objectives: To choose the best mode of delivery for term, frank or complete, breech presentation through studying the perinatal outcome of each mode of delivery decided when managing a group of pregnant ladies presented with breech delivery in our centre.
Methods: One hundred and fifty pregnant ladies presented at term with singleton, frank or complete, breech presentation for delivery in our centre during the period from May 2004 to August 2005.
Mode of delivery, parity, gestational age, maternal age, maternal medical illness, and birth weight where the variables that have been tested in each delivery included in the study to verify their relationship to perinatal outcome.
Results: No significant relationship is found between the occurrence of adverse perinatal outcome and the variables. However, mode of delivery was the major determinant of the perinatal outcome.
of the 150 pregnant ladies, 46 were delivered vaginally, 32 had elective caesarean section, and the remaining 54 pregnant, had undergone an emergency caesarean section because they were presented with labour. Thirteen (8.6 %) babies were adversely affected by the process of delivery, 9 (5%) of them were delivered by vaginal route, 3 (2 %) delivered by emergency caesarean section and one (0.6%) by elective caesarean section.
Conclusion: Elective caesarean section is regarded the safest way of delivery for those with term, frank or complete, breech presentation.
Key Words: Breech, Perinatal outcome, Cesarean Section (CS).

Abstract

Sewage sludge samples were collected from Al-rasafa and Al-karkh refinement stations which represent the main stations of Baghdad city. Samples were collected from all treatment stages: before, after, and during refinement processes.The High Purity Germanium Coaxial Detector system with energy resolution 1.8 keV for energy line 1333 keV of Co – 60 radioactive sources was used to measure radioactivity from both natural and artificial sources. GENIE – 2000 analysis the results statistically and qualitatively. The results showed that all sewage sludge samples exhibited natural radioactive level and sometimes less than the international regular standards, but Al–Karkh station showed increment in radioactive levels than Al– Rasafa station. Cs – 137 artificial radionuclide was detected in the samples with low concentration.

جُمعت عينات من المياه الثقيلة من محطات تصفية مدينة بغداد المتمثلة بمحطات تصفية الرستمية لجانب الرصافة ومحطة تصفية الكرخ لجانب الكرخ. أُخذت العينات من كل وحدات المعالجة في المحطات بحيث تمثل عينات قبل التصفية وأثناء المعالجة وبعد التصفية. أُستخدمت منظومة كاشف الجرمانيوم عالي النقاوة ذات ميز طاقي مقداره 2 keV لخط الطاقة 1333 keV التابع لنظير الكوبلت – 60 المشع لقياس مستوى النشاط الاشعاعي للعينات. حُللت العينات نوعياً وإحصائياً بأستعمال البرنامج 2000 - Genie . بينت النتائج أن العينات المأخوذة من هذه المحطات تحتوي على نشاط اشعاعي ضمن المعدلات الطبيعية المعتمدة دولياً وفي بعض الاحيان أقل من هذه المعدلات ولكن لوحظ أن هناك زيادة في مستويات النشاط الاشعاعي لمحطة تصفية الكرخ مقارنةً مع محطة الرستمية وتم الكشف عن وجود نظير السيزيوم – 137 الصناعي في عينات قبل التصفية وبتراكيز 2.51 بكريلكغم و 1.65 بكريلكغم لمحطتي الكرخ والرصافة على التوالي. وحُُُُسبت النسبة المئوية للتصفية وتفوقت محطة تصفية الكرخ على حساب الرصافة في تقليل تركيز نويدات النظائر المشعة.

Abstract

Background and objective: Ocular drug delivery research is challenging due to the presence of anatomical and physiological barriers. The ophthalmic preparation of diclofenac sodium (DC) for relieving ocular inflammation is presently available in the market only as an eye drop solution with low ocular bioavailability. The goal of our study was to prepare and evaluate an eye drop formulation, containing a nanocarrier, chondroitin sulfate (CS)-chitosan (CH)-nanoparticles (NPs) (CS/ CH-NPs) is being evaluated for improving the bioavailability of diclofenac sodium into the eye. Methods: Formulation was developed and optimized for three different variables (chondroitin sulfate, chitosan, and initial drug concentration). The developed formula was evaluated by various in-vitro parameters such as particles' size, entrapment efficacy, zeta potential, and in vitro release profile.Results: The particles' size, entrapment efficacy, and zeta potential of the best formulation were found to be 251.1±15.12nm, 73.2±5.3%, and 38.89±5.05mV, respectively. Furthermore, the best formulation showed a biphasic release profile, initial burst release in the first hour, followed by sustained release within 24hours.Conclusion: Promising results of in-vitro studies indicated that CS-CH-NPs could be a potential substitute for improved ocular delivery of diclofenac sodium.

Abstract

In this paper; a simple and powerful technique is proposed to encrypt and compress the color image in one step based on Compressive Sensing (CS) with using multi-chaotic system (Chen and Chua) as measurement matrix. The CS is used due to many properties; Greatly reduce the ratio of signal sampling, the size of capacity, power unitization, computational complexity that need to represent a sparse signal or images and lead signal processing into a new revolutionary era. In addition to all the above features; it combines encryption and compression in the one step. Also using chaotic system (Chen and Chua) as measurement matrix in CS provides high level of security to the encryption and compression image since each one of chaotic system has Three-dimension variable. The simulation results demonstrate the compression and encryption color image has low storage size and transmitted requirement, high security, large key size and low encryption time requirement since image compression and encryption in the same step, incoherence, key sensitivity, and resistance to brute force attack. Also the recovered image, has good quality (to human perception) and saves both the clarity and the characteristics of the image.

Abstract

Nontraditional machining processes are used for machining too hard, brittle and strong conductive materials. The aim of this research is to achieve an economic and efficient machining process in machining HSS by using wire cut machine. Experimental investigations were conducted on WEDM with using different machining parameters such as (pulse duration (μs), pulse interval (μs), Servo feed and Servo voltage (V)). The experiments were designed according to DOE, which is done by using Taguchi design parameter method to investigate the optimum machining parameters, which gives the best values for MRR and CS in order to achieve an economic and efficient machining process. The results obtained from the experimental work show that the optimum values of MRR and CS are obtained with the best values of Servo voltage (V), pulse duration (μs), pulse interval (μs), Servo feed and which they are presented with (A1, B3, C2 and D3) which they are equal to (20 v, 120 μs, 35 μs, and 450 mm/min).

Abstract

This study aims at examining teachers' attitudes of Basra University towards using Code-Switching(henceforth as CS), as an instructional strategy during the Language teaching process.The theoretical part of the study presents the various definitions of the term CS ,its types , its functions, the reasons that lie behind using it, the different attitudes towards using it in ELT and the use of CS as a pedagogical tool in teaching English as an FL. The practical part of the study deals with the research methodology . The study ends up with some conclusions and recommendations that regard CS as a sufficient means by which teachers can hold a positive attitude towards using it when they give their teaching lectures in the classrooms.
