شهد العالم مع بداية القرن الحادي والعشرين تدشين مرحلة جديدة من التطور شملت مختلف الميادين لاسيما في مجال التطورات العلمية والثورة المعلوماتية.. كما إن مسار الديمقراطية في بعض دول العالم يصبح سالكا خاصة في تركيا, فمنذ اواسط الثمانينيات من القرن الماضي فتح المجال السياسي امام قوى كانت مسحوقة ومهمشة, ويكاد ان لا يكون لها وجود في الحياة السياسية للنزول الى ساحة العمل السياسي اسوة ببقية القوى الفاعلية في المجتمع التركي, وان كانت الديمقراطية قد اثبتت هشاشتها في تركيا, في ذلك الحين لان الجيش التركي هو الحارس التقليدي للعلمانية قد جعل نفسه قيما على الحياة السياسية في البلاد. وفي عقد التسعينات من القرن الماضي استثمر التيار الاسلامي في تركيا هذا الجو فتوسع في اطروحاته الفكرية واعماله الاقتصادية والاجتماعية وقام بمد شبكة من العلاقات والنشاطات مستغلا الضعف الذي دب في المؤسسة العسكرية والجماعات العلمانية بعد ان تراخت قبضت الاولى نتيجة للشروط التي طالبت بها المجموعة الاوربية كخطوة لدخول تركيا المحفل الاوربي, فيما استخدمت الحكومة التركية الاسلام لاستيعاب الاطروحات اليسارية والتخفيف من غلواء واثار المطالبات القومية للاكراد والارمن وغيرهم من القوميات والاقليات في البلاد, وقد نجح في استثمار هذا التوجه زعيم التيار الاسلامي نجم الدين اربكان الذي حصل حزبه (حزب الرفاه) في عدد من الانتخابات على عدد من الاصوات اهلته للدخول الى البرلمان ومن ثم المشاركة في تشكيل الحكومة, مناصفة مع حزب الطريق القويم, وبعد حل حزب الرفاه من قبل السلطات التركية عام 1997. عاد التيار الاسلامي وجدد نشاطه لكن هذه المرة بصورة اكثر فاعلية, من خلال حزب العدالة والتنمية الذي انبثق عن حزب الرفاه ومجموعات من احزاب اخرى غير اسلامية وفئات شبابية مؤثرة لم ترتبط سابقا باية جهة حزبية . وتأسس في عام 2001 بزعامة رجب طيب اردوغان الابن الروحي لزعيم التيار الاسلامي في تركيا نجم الدين اربكان ..

... Show MoreIn this work pyrazolin derivatives were prepared from the diazonium chloride salt of 4-aminobenzoic acid. Azo compounds were prepared from the reaction of an ethanolic solution of sodium acetate and calculated amount of active methylene compound namely, acetyl acetone to obtain the corresponding hydrazono derivative (1). Cyclocondensation reaction of compounds (1) with hydrazine hydrate and phenyl hydrazine in boiling ethanol affording the corresponding pyrazoline-5-one derivatives of 4-aminobenzoic acid (2,3). Then compound (3) was reacted with thionyl chloride to give the corresponding acid chloride derivative(4), followed by conversion into the corresponding acid hydrazide derivative (5) carboxylic acid thiosemicarbazide (11), esters
... Show MoreBiodiesel production process was attracted more attention recently due to the surplus quantity of glycerol (G) as a byproduct from the process. Glycerol Utilization must take in to consideration to fix this issue also, to ensure biodiesel industry sustainability. Highly amount of Glycerol converted to more benefit material Glycerol carbonate (GC) was one of the most allurement compound derived from glycerol by transesterification of glycerol with dimethyl carbonate (DMC). Various parameters have highly impact on transesterification was investigated like catalyst loading (1-5) %wt., molar ratio of DMC: glycerol (5:1 – 1:1), reaction time (30 - 150) min and temperature (40 – 80) ᴼC. The Optimum glycerol carbonate yie
... Show MoreThe paper presents the design of a system consisting of a solar panel with Single Input/Multiple Outputs (DC-DC) Buck Converter by using Simulink dialogue box tools in MATLAB software package for simulation the system. Maximum Power Point Tracking (MPPT) technique depending on Perturb and Observe (P&O) algorithm is used to control the output power of the converter and increase the efficiency of the system. The characteristics of the MSX-60 PV module is chosen in design of the system, whereas the electrical characteristics (P-V, I-V and P-I curves) for the module are achieved, that is affected by the solar radiation and temperature variations. The proposed design module has been found to be stable for any change in atmospheric tempera
... Show MoreSolid‐waste management, particularly of aluminum (Al), is a challenge that is being confronted around the world. Therefore, it is valuable to explore methods that can minimize the exploitation of natural assets, such as recycling. In this study, using hazardous Al waste as the main electrodes in the electrocoagulation (EC) process for dye removal from wastewater was discussed. The EC process is considered to be one of the most efficient, promising, and cost‐effective ways of handling various toxic effluents. The effect of current density (10, 20, and 30 mA/cm2), electrolyte concentration (1 and 2 g/L), and initial concentration of Brilliant Blue dye (15 and 30 mg/L) on
Background: Odontogenic tumors are a diverse group of lesions with a variety of clinical behavior and histopathologic subtypes, from hamartomatous and benign to malignant. The study aimed to examine the clinical and pathological features of odontogenic tumors in Baghdad over the last 11 years (2011–2021). Materials and Methods: The present retrospective study analyzed all formalin-fixed, paraffin-embedded tissue blocks of patients diagnosed with an odontogenic tumor that were retrieved from archives at a teaching hospital/College of Dentistry in Baghdad University, Iraq, between 2011 and 2021. The diagnosis of each case was confirmed by examining the hematoxylin and eosin stained sections by two expert pathologists. Data from pati
