Background: Laparoscopic sleeve gastrectomy has gained more popularity as an independent bariatric procedure because laparoscopic sleeve gastrectomy was reported to be an effective, safe, and time-savingprocedure, leading to adequate weight loss for morbidly obese patients and becoming one of the most common procedures performed for the treatment of morbidly obese patients in the last few years until now.
Objectives: The aim of this study is to compare two different techniques of the reinforcement of staple line during LSG in the reduction of major complications (bleeding and leak).
Patients and methods: prospective randomized study of a consecutive series of 126 patients that underwent LSG between April 2014 till August 2015. Patients were randomly enrolled in two different techniques of reinforcing the staple line during LSG, Group A consisted of 63 patients that underwent sleeve gastrectomy using Ethicon Endo GIA stapleTM with staple line oversewn using 2.0 prolene continuous suture, group B also 63 patients who had the staple-line oversewn with a continuous suture using V-locTM and Covidien Endo GIA tristapleTM.
Results: 126 patients who underwent LSG, 82(65%) were women and 44(35%) were men. Median age was 36 years (range, 19–58 years) and median preoperative BMI was 45.4 kg/m2 (range, 37–62 kg/m2), Three patients (4.76%)from group (A) and 2 patients (3.17%)from group (B)developed primary hemorrhage (within the first 24 hours post operatively), overall bleeding rate in both groups was (3.96%), no leak in both groups and no mortality.
Conclusion: laparoscopic sleeve gastrectomy is a safe procedure as a sole weight reduction operation. The combination of meticulous surgical technique, reinforcement of the gastric staple line, lead to decrease the incidence of staple line leak whatever the suture material or stapler type used, but there is no significant decrease in the incidence of bleeding with staple line reinforcement.
It has become necessary to change from a traditional system to an automated system in production processes, because it has high advantages. The most important of them is improving and increasing production. But there is still a need to improve and develop the work of these systems. The objective of this work is to study time reduction by combining multiple sequences of operations into one process. To carry out this work, the pneumatic system is designed to decrease\ increase the time of the sequence that performs a pick and place process through optimizing the sequences based on the obstacle dimensions. Three axes are represented using pneumatic cylinders that move according to the sequence used. The system is implemented and
... Show MoreThe auditory system can suffer from exposure to loud noise and human health can be affected. Traffic noise is a primary contributor to noise pollution. To measure the noise levels, 3 variables were examined at 25 locations. It was found that the main factors that determine the increase in noise level are traffic volume, vehicle speed, and road functional class. The data have been taken during three different periods per day so that they represent and cover the traffic noise of the city during heavy traffic flow conditions. Analysis of traffic noise prediction was conducted using a simple linear regression model to accurately predict the equivalent continuous sound level. The difference between the predicted and the measured noise shows that

TRIPS agreement was The first to apply protection by patents. However, this type of protection, which grants exclusive and monopoly rights to patent owners, came at the expense of developing countries which are considered rich in biodiversity and also at the expense of traditional and poor knowledge of modern technologies. The release of new plant varieties has led to the emergence of biopiracy and looting of the rights of developing countries without a license
Well-dispersed Cu2FeSnSe4 (CFTSe) nanoparticles were first synthesized using the hot-injection method. The structure and phase purity of as-synthesized CFTSe nanoparticles were examined by X-ray diffraction (XRD) and Raman spectroscopy. Their morphological properties were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The average particle sizes of the nanoparticles were about 7-10 nm. The band gap of the as-synthesized CFTS nanoparticles was determined to be about 1.15 eV by ultraviolet-visible (UV-Vis) spectrophotometry. Photoelectrochemical characteristics of CFTSe nanoparticles were also studied, which indicated their potential application in solar energy water splitting.
The study dealt with The impact of dangerous goods Transportation for Maritime carrier responsibility, the study was exposed to the definition of dangerous goods. the study also dealt with the impact of IMDG code on the responsibility of the carrier, and the duties of the parties, as the study spotlights The duty of the carrier to prepare a compatible ship for dangerous goods transport, as well as the duty of the carrier to preserve the goods while highlighting to the difference in this obligation while transporting dangerous goods, and the study also reviewed the duties of the shipper, for example, his duty to inform the carrier with the dangerous nature of the goods and the role of IMDG code in dealing with the danger of these goods. t
