In this study, simply supported reinforced concrete (RC) beams were analyzed using the Extended Finite Element Method (XFEM). This is a powerful method that is used for the treatment of discontinuities resulting from the fracture process and crack propagation in concrete. The mesoscale is used in modeling concrete as a two-phasic material of coarse aggregate and cement mortar. Air voids in the cement paste will also be modeled. The coarse aggregate used in the casting of these beams is a rounded aggregate consisting of different maximum sizes. The maximum size is 25 mm in the first model, and in the second model, the maximum size is 20 mm. The compressive strength used in these beams is equal to 26 MPa.

In real conditions of structures, foundations like retaining walls, industrial machines and platforms in offshore areas are commonly subjected to eccentrically inclined loads. This type of loading significantly affects the overall stability of shallow foundations due to exposing the foundation into two components of loads (horizontal and vertical) and consequently reduces the bearing capacity.

Based on a numerical analysis performed using finite element software (Plaxis 3D Foundation), the behavior of model strip foundation rested on dry sand under the effect of eccentric inclined loads with different embedment ratios (D/B) ranging from (0-1) has been explored. The results display that, the bearing capacity of st

Background: Visceral Leishmaniasis( VL ) is a systemic infection of the reticulo- endothelial system that could affect the immune system and biochemical parameters like the concentration of Copper which may be significantly hanged .
Objective: The study aims to evaluate the level of cytokines (INF- γ ,IL-10 ) and trace element (Cu ) in Visceral Leishmaniasis in children after diagnosis .
patients and Methods: A total of 98 children, whose their ages ranged (6 menthes -5 years) were attending the Central Public Health Laboratory and Teaching Laboratories of Medical City, who were suspected to be infected with kala- azar, who were diagnosed by both IFAT technique and Rapid Kala-azar (r-K39) detecting test and trying to evaluate the

     In this paper we tend to describe the notions of intuitionistic fuzzy asly ideal of ring indicated by (I. F.ASLY) ideal and, we will explore some properties and connections about this concept.

Background: Unstable pelvic ring fractures (PRF) are high energy trauma, commonly associated with systemic and soft tissues elements injures, the external fixation as an emergency and final treatment is one of the options in its management.

Objective: to evaluate the value and role of external fixation for unstable (PRF) and its clinical outcomes.

Patients and methods: twenty one patients with unstable P.R.F have been treated by external fixation , they were 16 men and 5 women ,their  average age was 28 years (range ;18-60 years) , two thirds of the cases were due to road traffic accident , 85% were hemodynamicaly unstable , urological and neurological, anorectal injuries were the commonest associate

This research involved synthesis of new β-Lactam derivative from Azo compound[4-amino-N-(pyrimidine-2-yl)-3-(pyrimidine-2-yldiazenyl) benzene sulfonamide] (S1) record previously by many steps. Starting conversion the free amino group in an azo comp. to chloro acetamide derivative(S2), then reacted it with urea to give the oxazole ring  derivative (S3) that which containing free amino group. The condensation reaction between the amino group and P-bromobenzaldehyde to produce Shiff base (B14). Finally staudinger's cyclo addition reaction go run between the Shiff base derivative (B14) and chloro acetyl chloride in the presence of tri ethyl amine (Et₃N) as Base catalyst and dioxane a

The investment contract that has a foreign element is considered amongst the contracts that have their legal and international economical weight, for what it represents in all countries’ economies, and achieving progress in many fields that investment has its effects on their growth and establishment as its at the centre of everyone’s attention. As well as that the variety in opinions and the presence of differences in the contents of these contracts, and the confusion between them and other international contracts, and the considerable interest jurists have in them have all led to not having a legal definition for them, as most definitions the describe them are more economical than they are legal, and the reason for that is that law

The research targets study of influence of additives on sand mold’s properties and, consequently, on
that of carbon steel CK45 casts produced by three molds. Three materials were selected for addition
to sand mix at weight percentages. These are sodium carbonates, glycerin and oat flour. Sand molds
of studied properties were produced to get casts from such molds. The required tests were made to
find the best additives with respect to properties of cast. ANSYS software is used to demonstrate
the stresses distribution of each produced materials. It is shown that the mechanical properties of
casts produced is improved highly with sodium carbonates and is less with oat flour and it is seem a
few with glycerin additives

The main aim of this research paper is investigating the effectiveness and validity of Meso-Scale Approach (MSA) as a modern technique for the modeling of plain concrete beams. Simply supported plain concrete beam was subjected to two-point loading to detect the response in flexural. Experimentally, a concrete mix was designed and prepared to produce three similar standard concrete prisms for flexural testing. The coarse aggregate used in this mix was crushed aggregate. Numerical Finite Element Analysis (FEA) was conducted on the same concrete beam using the meso-scale modeling. The numerical model was constructed to be a bi-phasic material consisting of cement mortar and coarse aggregate. The interface between the two c
