Cyclic Voltammetric Determination of Methylparaben and Propylparaben in Pharmaceutical Preparations
No full textIn this study, a new technique was developed using rapid Cyclic voltammetry at hanging mercury electrode (HDME) and The anodic oxidation and cathodic reduction for the detrmination of two commonly used parabens (methylparaben (MP) and propylparaben (PP)) in maleate buffer at (pH 6) solution. The results show that the charge transfer processes were reversible. The method is used to determine methyl and propyl paraben in concentration range (2.66 × 10-8, 1.07 × 10-7) M at pH = 6 respectively. This method was applied successfully for the assay of the pharmaceutical preparations of the considered drugs.Key words: Cyclic voltammetry,methyl and propyl paraben, drug
التعريف بأخلاق اليهود ونفسياتهم في رواية ((علي أبواب خيبر)) لنجيب الكيلاني
No full textلم يترك مجالا للرواية العربية أن تنشأ بمقوماتها الذاتية و تختمر بعناصرها الداخلية وتظهر بهويتها العربية بل عليها طابع التقليد و التبعية وسارت في إتجاه غربي شكلا ومضمونا وهذا هو السبب وراء محاولات لإخراج الرواية بسمات عربية إسلامية والدكتورنجيب الكيلاني من الشخصيات الأدبية التي ساهموا في هذه الساحة فهو أول من جعل من ثوابت العقيدة وأخلاقيات الإسلام هدفا روائيا؛ واستطاع ان يقدم تصويرا من أهم صراع وقع علي الساحة الايدئولوجية بين القيم السامية التي يمثلها الإسلام والأفكارالسلبية التي تمثلها اليهود. ويحاول هذا البحث عن طريق قراءة النص الروائي والتركيز علي مضمونه بحثا وتحليلا أن يصور مدي نجاح الكاتب في الاستلهام من التاريخ وترسيخ مفاهيمه الساميه في القارئ وتسيير مشروع اسلمة الرواية العربية و يظهر مدي تمكنه من ابراز اهم صراع وقع في التاريخ بين الانسانية والايديولوجي السلبي و يبدو ان الكاتب ابدع اتجاها اسلاميا متطورا في كتابـه الروايه الإسلامية
Synthesis and Characterization of Heterocyclic Compounds from 8-Hydroxyquinoline
No full textThis research includes synthesized of heterocyclic compounds derivatives containing different rings through the use of 8- hydroxyquinoline as starting material and a reacted with p- phenylene diamine and benzldehyde derivatives, These compounds were characterized by melting point and FT.IR and 1HNMR Spectroscopy
Preparation of Activated Charcoal with High Surface Area from an Agriculture Wastes and Industrial Residues
No full textThis work was concentrated on preparation of activated carbon which also call (charcoal) from natural agricultural wastes (leg & leaves and empty ear of corn, Wheat & Barley grass and herb residues) and industrial residues (Paper drafts and Sawdust). These residues were treated first with Sodium Hydroxide (1:2) (1 of the raw materials : 2 of NaOH), then burning at 550 ± 25 °C for three hours to complete the carbonization process. The reaction mixture was purified by washing with distillation water and neutralized using 10% Hydrochloric acid. Reflux for one hour, filtrate and washing with distilled water, and leaves to dry at 110 – 120 °C for 24 hours. The physical properties of preparing activated carbon were determined and compared with a commercial activated carbon which supply by B.D.H. chemical compan
EFFECT OF SOAKING ON THE COMPACTION CHARACTERISTICS OF AL-NAJAF SAND SOIL
No full textThe process of salt dissolution is a reason of structure severe deformation by effective settlement. This paper investigates the effect of soaking process on the soil samples from site near the Faculty of Engineering at University of Kufa. Four samples (S1, S2, S3 and S4) were taken from different locations near the selected site. These samples were soaked for two weeks' duration then tested with standard Proctor to estimate the change in the maximum dry density with reference one (natural samples). http://dx.doi.org/10.30572/2018/kje/09020
Asthma knowledge in a sample of students at college of Health and Medical Technologies in Baghdad
No full textBackground: Bronchial Asthma (BA) is a chronic inflammatory, disease of the airway characterized. by therecurrent attacks, of the shortness, of breath that associated with wheezing, recurrent cough as well as chest tightness ,may be get worse, during exposure to smoke, dust, change in weather. The prevalence, of a,sthmawas .increasing globally, so the natural history of asthma is still,not well defined it thought to be of genetic and environmental factors represented by exposure to allergens. Aim: To determine the level of knowledge about asthma among students in College of health and medical technologies. Methodology: one hundred forty college students were selected using a designed questionnaire for collect information of students about,the,epidemiology of asthma, symptoms, trigger factors and source of their information. The knowledge, score was estimated the,measure level of the ,students’ knowledge.Results,: More than half of the sample had moderate knowledge level
Influence of various bioprocess factors on production of lipase from Pseudomonas aeruginosa

Volumetric and Viscometric studies of vitamin (B6) in aqueous and acidic media at different temperatures
No full textDensities and viscosities of pyridoxine(B6) in aqueous and acidic solutions at 298.15-313.15K have been measured. By Masson equation the experimental values of densities were used to estimate some significant parameters, such as apparent molal volume(Φv), limiting apparent molal volume(Φv0) and slop Sv, and the viscosity data have been investigatevia Jones-Dole equation, and the derived parameters, Jones-Dole coefficient B, and Falkenhagen coefficient A. The results were interpreted in term of solute-solute and solute –solvent interaction. The difference of B coefficient with temperature (dB/dT), was also determined the positive values indicate that pyridoxine(B6)in aqueous and acidic solutions is structure making
