فاعلية التمويل الخارجي في تحقيق التنمية الاقتصادية في العراق
تعد مشكلة التمويل من اعقد المشكلات التيتواجهها التنمية الاقتصادية في مختلف البلدانالنامية بشكل عام وفي الع ا رق بشكل خاص، اذلم تعمل الحكومة الع ا رقية المبادة طوال ثلاثينعاما من تمويل التنمية الاقتصادية بالشكل الذييؤدي الى تطوير القطاعات غير النفطية واقامةقاعدة اقتصادية عريضة ومتطورة ذات مصادردخل متنوعة ومستدامة. ومن ثم تحقيق النمووالتنمية على الرغم من توافر العوائد الماليةالضخمة من القطاع النفطي، بسبب الحروبالتي قادها النظام المباد وما تبعها من عقوباتاقتصادية دامت لأكثر من عقد، فضلاً عنضخامة المديونية الخارجية وما تبعها من خدمةالدين والتعويضات

EFFECTS OF CRAB SHELL AND CHARCOAL REINFORCEMENTS ON THE MECHANICAL PROPERTIES OF POLYESTER MATRIX COMPOSITES
Composites are produced when two or more materials are used to give combination of properties that cannot be attained otherwise. This study aims to use crab shell and charcoal reinforcements to enhance the mechanical properties of polyester composites and decrease the environmental pollution caused by the agro waste. In this study, 5 – 25 wt. % of 100 g of grounded charcoal and crab shell with an average particles size of 150 μm were used for polyester matrix composites. Flexural strength, impact resistance, hardness and elastic modulus tests were carried out on the developed samples. The microstructure of the samples revealed a uniform distribution of the reinforcements within the polymer matrix with different morphology of the biocomposites. The results showed that the greatest flexural strength value of 361.37 MPa was obtained at 25 wt. % and the highest Brinell hardness number (BHN) was 118.27 at 20 wt. %. However, the highest modulus of elasticity was 335.63 MPa at 15 wt. % reinforcement with crab shell reinforced and was 308.64 MPa with charcoal reinforcements at 20 wt. %. Furthermore, the highest impact energy was 5.49 J for crab shell and 5.31 J for charcoal reinforced polyester composite. The development of the biocomposites of these materials will decrease the environmental pollution and improve the properties of the polyester matrix composites for engineering applications
Number of Spinal-Convex Polyominoes
In his paper we describe a restricted class of polyominoes called spinal-convex polyominoes. Spinal-convex polyominoes created by two columns such that column 1 (respectively, column2) with at most two set columns sequence of adjacent ominoes and column 2 (respectively, column1) with at least one set column sequence of adjacent ominoes. In addition, this study reveals new combinatorial method of enumerating spinal-convex polyominoes. Keywords—: Polyominoes, Spinal-convex, Set column sequence, enumerating

Frequency of ToxA and ExoS genes in Pseudomonas aeruginosa isolates obtained from different clinical specimens
The present study carried out in Azady teaching general hospital in Kirkuk city during the period from August 2017 to May 2018, to determine the frequency of ToxA gene and ExoS gene in P. aeruginosa isolates. Pseudomonas aeruginosa (100) isolates had been obtained from (1260) different clinical specimens, High prevalence of P. aeruginosa found in isolates obtained from burn swabs. Regarding to genders and ages, P. aeruginosa presented in females (58%) more than males (42%), regarding to age groups, P. aeruginosa presented more frequently (26%) in age group (20-30) followed by children (1-10) years that formed (22%). Molecular detection of virulence genes had been done by using conventional PCR technique, regarding to prevalence of ToxA and ExoS genes, ToxA gene presented (96%), ExoS gene (92%). Regarding to the distribution of genes in clinical specimens, ToxA gene present (100%) in all clinical specimens except in urine samples (90.9%) and low percentage found in sputum (50%). ExoS gene present (100%) in all isolates, while ExoS gene less frequently presented in ear swab isolates ( 83.3%) than other specimens, followed by urine specimens (81.8%), in bronchial washes isolates ExoS gene was absent. This study aims to determine the frequency of ToxA gene and ExoS gene in P. aeruginosa isolates that obtained from different clinical specimens
CONNECTION BEHAVIOR IN COMPOSITE PROFILED STEEL SHEET WITH FERROCEMENT (PSSF) SYSTEM
This paper concerns with the behavior of the connections in the composite Profiled Steel Sheet with Ferrocement (PSSF) systems. The PSSF panels is a light weight composite panel consists of a profiled steel sheet (PSS) and ferrocement panel connected together by either mechanical fasteners or by epoxy adhesive resin. Ten push-out specimens were tested. The veriables were the strength of morter and the volume friaction of wire mesh for ferrocement panels, and types of connection between the two components. The ultimate load, the load slip relationship, and modes of failure were recorded. The results showed that the specimens connected by using* bolts of 10 mm diameter can sustain load greater by 64% than those connected by using bolts of 5 mm diameter. The ultimate load was found not to be inflenced** when the strength of ferrocement is increased from 35 MPa to 45 MPa. Also the effect of volume fraction of wire mesh was observed to enhance slightly the ultimate load when the layers of wire meshs is increased from 2 to 3 layers. For the specimens made by connecting the ferrocement components to the PSS by adhesive epoxy layer, a rigid connection was obtained and sudden separation occurred between the ferrocement component and steel sheet after local buckling of PSS
