Abstract

This paper presents an experimental investigation to predict the load-deformation behavior of High Strength reinforced concrete beams that failed in flexure and were repaired by epoxy injection.
Four simply supported reinforced concrete beams with dimensions of (120*230*2550mm) were investigated after repairing with epoxy resin injection method. Beams B1 and B2 have tensile steel ratio of 0.0099, while Beams B3 and B4 have tensile steel ratio of 0.0177.
Deflections were measured at first third, second third from the support and at mid span for all beams by using dial gauges.
The behavior achieved for resin injected high-strength reinforced concrete beams was similar to that of the original beams. However, the cracks do not re-open after retesting. Instead, new nearby cracks are developed and the repaired beams showed a greater ductility than the original beams

يقدم هذا العمل بحثاً عملياُ عن سلوك العتبات الخرسانية المسلحة المصنوعة من الخرسانة عالية المقاومة الفاشلة بالأنثناء و المُصلّحة بوساطة حقن التشققات (بالايبوكسي). تم استخدام أربعة عتبات خرسانية مسلحة عالية المقاومة بسيطة الاسناد. بأبعاد( 120*230 *2550 ملم ) حيث تمت دراستها بعد إصلاحها بطريقة الحقن بالأيبوكسي. العتبات B1 و B2 ذات نسبة حديد تسليح تساوي (0099و0) بينما العتبات B3 و B4 فكانت نسبة حديد التسليح فيها (0177و0).تم قياس الهطول عند الثلث الأول والثاني من المسند وعند منتصف الفضاء للعتبة قبل وبعد الأصلاح من خلال مقاييس مدرجة.طريقة التصليح من خلال الحقن بالأيبوكسي أظهرت تصرفاً لعلاقة الحمل-الهطول مشابهة لتلك العلاقة التي ظهرت للعتبات قبل عملية الأصلاح بهذه الطريقة مع فروق طفيفة ، أن التشققات لم تظهر مرة أخرى بعد الاصلاح بينما تشكلت تشققات جديدة قريبة. و بصورة عامة ، فان السلوك الإنشائي للعتبات الخرسانية ذات المقاومة العالية المصلحة كان مشابها لسلوك العتبات الاصلية مع مطيلية أعلى

Abstract

Incremental sheet metal forming is a modern technique of sheet metal forming in which a uniform sheet is locally deformed during the progressive action of a forming tool. The tool movement is governed by a CNC milling machine. The tool locally deforms and by this way the sheet with pure deformation stretching. The aim of the present work is to inspect, experimentally, the state of the residual stresses induced in SPIF parts made by A1050 aluminum. The forming surface was measured at four different angles using a ORIONRKS 6000 test (the X-ray diffraction technology was used to detect the residual stress) measuring instrument with the angles (0o, 15o, 30o and 45o) and the average residual stress value is recorded in (MPa), the residual stress in original blanks is (-6.29MPa). This specialized stress analysis system using the side-inclination method includes stress analysis software, the stress analysis sample stand and X-ray tube. A comparison study is made for tabulated values and experimental values for residual stress by using ANOVA model with the contribution of rotational speed, feed rate and forming depth with respect to residual stress is (63.7, 4.3 and 32)% respectively..

Abstract

For the sake of guarding the environment from the vital problems that results from the toxic effects of lead components, lead free (LKNN6-0.5%CeO2/polyester) piezoelectric composite are prepared in this work using cold press technique. Firstly, the lead free (LKNN6-0.5%CeO2) piezoceramics are prepared using normal sintering technique. The dielectric and piezoelectric properties of the composites were examined as a function of the volume fraction of ceramic particles, all composites showed well dispersion of the piezoceramic particles in the polyester matrix as shown in SEM images. The piezoelectric and dielectric coefficients were found to be improved as the concentration of ceramic particles increases. Although the procedure is simple, the composite prepared in this study exhibited better piezoelectric and dielectric constants with (d33=41 and Ԑr=157) at (80%) volume fraction.

Abstract

Background: Surgical sphincterotomy (SS) has been the most commonly used treatment for chronic anal fissure (CAF). Although effective, it is associated with gas and or fecal incontinence in (0-20%) inter-sphincteric Botulinum Toxin A (BTXA) injection is a non-surgical technique that may be used as an option under certain circumstances for treatment of such condition.Objective: To verify the effectiveness of the BTXA injection in relieving symptoms and healing of chronic anal fissures.Methods: Thirty patients with CAF were treated by BTXA 1 U/kg injected into the inter-sphincteric plane; as an outpatient procedure, patients were re-evaluated after 1 week, and then every 2 weeks until the fissure healed or surgery was required. The patients were followed up for one year by regular attachment through phone call or visit, to evaluate the effects of treatment. Results, complications and follow up were recorded.Results: In 25 patients (83%), the pain was disappeared after the first week; 20 patients (66%) presented with a complete healing of the fissure in a period ranging between 1 to 3 months. Gas incontinence was reported in 2 patients (6%) and solved spontaneously. No major complications were found, in 3 cases (10%) surgery was needed later on.Conclusion: Since it avoids the greater risk of incontinence associated with SS, and it can be done as outpatient procedure without admission or general anesthesia. We recommend the use of BTXA as the first therapeutic approach for patients with chronic anal fissure.Keywords: Botulinum Toxin A, anal fissure.Citation: Nashwan Q. Mahgoob, Muhammed M. kamal.

Abstract

Background:Osteoarthritis (OA) is a degenerative joint disease caused by gradual loss of cartilage. Telmisartan is an angiotensin II receptor antagonist, and act as a partial agonist on the nuclear peroxisome proliferator-activated receptor-gamma (PPAR-γ), that has been reported to exert anti-inflammatory effects.Objective:To evaluate the potential anti-inflammatory effect of telmisartan in patients with knee OA.Methods:Forty-two patients with painful knee OA were allocated into 2 groups, group (1): patients treated with naproxen tablets (500 mg/12 hr), telmisartan tablets (40 mg/day) and omeprazole (20 mg/day) for 3 months, while group (2): patients treated with naproxen tablets (500 mg/12 hr) and omeprazole (20 mg/day) for 3 months. The serum levels of IL-1β, high-sensitivity C-reactive protein (hs-CRP), TNF-α and erythrocyte sedimentation rate (ESR) were measured before and after 3 months of treatment.Results:Telmisartan when used in combination with naproxen resulted in significant decrease in serum levels of IL-1β and hs-CRP, higher than that produced by naproxen when used alone. The mean TNF-α level and ESR was decreased non-significantly in both study groups.Conclusion:Administration of telmisartan as an adjuvant therapy to naproxen in knee OA patients produced a significant decrease in the serum levels of IL-1β and hs-CRP, though no clear effect on TNF-α and ESR was noticed after 3 months treatment. Accordingly, many promising preventive strategies emerged from the available results since telmisartan relatively reduce the inflammatory burden in OA patients. The dose and duration of telmisartan treatment in this study did not indicate a risk of hypotension.Keywords:Telmisartan, naproxen, osteoarthritis, cytokinesCitation:Hmood SA, Mohammed MM, Kamal YM, Jasim NA.
