Most solar collectors in Nigeria are mounted without consideration of optimum tilt angle for maximum radiation. To address the gap, a flat plate surface collector area 0.15 m2, hinged on horizontal support quick adjustment inclination between 0 to 90o was fabricated marked out at 1o intervals telescopic leg graduated degrees. Measurement radiation varying degrees taken 12:00 noon and 2.00 pm 4 ...

der folgende text, der unter der betreuung von herrn dr. touraj rahnema entstanden ist, erw?hnt zuerst kurz die bestimmenden züge der literarischen schule, die im europ?ischen kulturraum allgemein als romantik verstanden wird, will aber darüber hinaus die romantik als eine art lebenshaltung und kunstverst?ndnis begreifen, die unabh?ngig von einer bestimmten kunstperiode genauso auch in ?stliche...

In die manufacturing industries surface roughness is considered as a vital quality characteristic in order to retain the consumers’ satisfaction. On the other hand, manufacturers want to minimize the machining time which eventually reduces their cost. This research deals with an optimization problem to minimize the machining time (T) for end milling operation on hot die steel (H13), subject to ...

This article focuses on the optimization of tilt angle for solar panels in Gulf Cooperation Council (GCC) countries. The is a crucial factor that affects amount radiation received by panel. study uses mathematical model to calculate optimal based latitude and longitude location compares results with PVWatts calculator. importance selecting maximizing energy production emphasized. finds calculat...

in this paper, multi-stage optimum design of composite pressure vessels is presented. the design variables for composite vessels include the head shape, the winding angle, the layer thickness, the number of layers, and the stacking sequence. a parameter called modified shape factor is introduced as an objective function. this parameter takes into account the effects of the internal pressure and...

The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

Nemaline myopathy is a congenital neuromuscular disorder, which primarily affects the thin filaments. Clinically the most important feature is muscle weakness; however, this weakness is poorly understood. The present investigation aimed to determine the torque angle relationship of the knee extensor muscles during in vivo muscle contractions in a family with a novel phenotype of nemaline myopat...

To achieve uniform thickness of coated films using non-Newtonian fluids, we are often required well-designed geometries of flow channel in a slot die. This is the case especially for fluids with the properties of both shear thinning and yield stress which is non-negligible in a range of low shear rate such as in an intermittent die coating. In the present work, flow in the slot die has been stu...

Many people who are terminally ill would prefer to die at home. Integrated professional working is necessary to enable patients to remain in their homes for end of life care. This article describes how an integrated district nursing team in Lincolnshire provides end of life care to patients in the community. The team uses the Gold Standards Framework and the Liverpool Care Pathway to provide op...
