Affective Factors on Reliability of Laboratory Tests Based on ISO 17025:2005

تعد معولية الفحوصات المختبرية الركيزة الأساسية في الجانب التطبيقي لجودة المشاريع إلانشائية، إذ لا يمكن قبول أو رفض المواد إلانشائية المستخدمة في تلك المشاريع إلاٌ بعد مرورها بالفحص المختبري الذي يتم بموجبه القبول أو الرفض لتلك المواد. أن العديد من المنظمات أخذت بالسعي نحو تحقيق الميزة التنافسية، وذلك بتقديم خدماتها بجودة عالية من خلال تطبيقها معايير إدارة الجودة الشاملة، فكان من الضروري للمختبرات إلانشائية تبني أدارة الجودة اسلوبا في عملها، لاسيما تطبيق معايير المواصفة العالمية ISO 17025:2005 مما يحسن أداء هذه المختبرات من الناحية الإدارية والفنية. يتضمن هذا البحث دراسة إحصائية لعينة من المختبرات إلانشائية وشركات المقاولات إلانشائية ودوائر تنفيذ المشاريع في بعض المؤسسات الحكومية، لتحديد العوامل المؤثرة على معولية (موثوقية) الفحوصات المختبرية، واثبتت النتائج لكل محور هي (مؤثرة، مؤثرة جدا) بحسب ما تم وضع ارقام إليها إذ ستقدم المنهجية المتبعة في البحث توصيات ومقترحات تساعد الكوادر العاملة في المختبرات بالتركيز على العوامل المؤثرة على معولية الفحوصات والتعامل معها على وفق معايير المواصفة العالمية ISO 17025:2005.The reliability of the laboratory tests is the main pillar in the applied side of the quality of the construction projects. The construction materials used in these projects cannot be accepted or rejected until they have passed the laboratory examination according to which these materials are accepted or rejected.. Many organizations have sought to achieve the competitive advantage by providing high quality services through the implementation of the overall quality management standards. It was necessary for the construction laboratories to adopt the quality management method in their work, in particular the application of the standards of ISO 17025: 2005, Which improve the performance of these laboratories in terms of administrative and technical. This research includes a statistical study of a sample of construction laboratories, construction contracting companies and project implementation entities in some government departments to determine the factors affecting the reliability of the laboratory tests. The methodology used in the research will provide recommendations and suggestions to help the laboratory staff focus on the factors influencing the Reliability of tests and handling them according to the  ISO 17025: 2005

An Overview of Differences Between Types of Chimeras and Their Impact on Humans

Chimera has several important definitions that are common to each other, where he is known a single creature that is made up of two or more separate populations of genetically unique cells that originated from various zygotes. Definition can be interpreted as cells from one person might appear in another individual in a process known as chimerism. These cells may be incorporated into the parenchyma or they may circulate. Chimeras are divided into several types depending on several factors such as the percentage of chimera cells in the body of the organism neighborhood, origin, or other reasons, which includes microchimeras, natural human macro-chimeras and man-made chimeras. Chimeric cells in human can arise from three significant sources, namely originating from gestation, blood transfusions, and transplants

EFFECT OF HERBICIDES ON GROWTH, GRAIN YIELD AND QUALITY OF BARLEY

This experiment was aimed to study the effect of   herbicide (lintur @180 g.ha-1 + Axial @1.5 L.ha-1, Navigator @ 1.25 L.ha-1 and the control treatment) in the companion weeds. Besides, grain yield and its components of three cultivars of barley (IPA 99, Buhooth 256, Aldebaran). The experiment was carried out according to RCBD, within split plot arrangement using three replicates. The cultivars represented the Main-plots, while herbicides and control treatments represented the sub-plots. The second included a laboratory experiment with four replicates of 50 seeds per replicate to study some grain quality characteristics resulting from the first field experiment. The results were showed the superiority of the Buhooth 256 cultivar in number of spikes, weight of 1000 grains, and the grain yield with an average of 495.10 spike.m-2, 22.23 g, and 1.46 ton.ha-1, respectively. Buhooth 256 also recorded the best results in increasing the percentage of weed control, reducing weed dry weight, and increasing the inhibition ratio. The same cultivar exceeded in most characteristics of grain quality. The treatment of herbicides (lintur + Axial) exceeded by achieving the highest average number of spikes of (471.60 spike.m-2), and the highest number of grains per spike with (51.77 grain.spike-1). Coupled with the weight of 1000 grains (21.47 g), and the highest grain yield (1.53 ton.ha-1)

SPARC 2017 retrospect & prospects : Salford postgraduate annual research conference book of abstracts

Welcome to the Book of Abstracts for the 2017 SPARC conference. This year we not only celebrate the work of our PGRs but also the 50th anniversary of Salford as a University, which makes this year’s conference extra special. Once again we have received a tremendous contribution from our postgraduate research community; with over 130 presenters, the conference truly showcases a vibrant PGR community at Salford. These abstracts provide a taster of the research strengths of their works, and provide delegates with a reference point for networking and initiating critical debate. With such wide-ranging topics being showcased, we encourage you to exploit this great opportunity to engage with researchers working in different subject areas to your own. To meet global challenges, high impact research inevitably requires interdisciplinary collaboration. This is recognised by all major research funders. Therefore engaging with the work of others and forging collaborations across subject areas is an essential skill for the next generation of researchers

Effect of Heat Treatment on Corrosion Behavior of Duplex Stainless Steel 2507 in Artificial Saliva

The effect of heat treatment of duplex stainless steel 2507 on its corrosion in artificial saliva is studied. The microstructure of the steel is analyzed using scanning electron microscopy and x-ray diffractometry. The hardness and the corrosion resistance of the alloy are determined and potentiodynamic measurements are performed. An optimum mode of heat treatment is suggested for raising the corrosion resistance of steel 2507

Data reduction in headspace analysis of blood and urine samples for robust bacterial identification

This paper demonstrates the application of chemical headspace analysis to the problem of classifying the presence of bacteria in biomedical samples by using computational tools. Blood and urine samples of disparate forms were analysed using a Cyrano Sciences C320 electronic nose together with an Agilent 4440 Chemosensor. The high dimensional data sets resulting from these devices present computational problems for parameter estimation of discriminant models. A variety. of data reduction and pattern recognition techniques were employed in an attempt to optimise the classification process. A 100% successful classification rate for the blood data from the Agilent 4440 was achieved by combining a Sammon mapping with a radia( basis function neural network. In comparison a successful classification rate of 80% was achieved for the urine data from the C320 which were analysed using a novel nonlinear time series model. (c) 2005 Elsevier Ireland Ltd.
