abstract strawberry is one of the most important fruit crops in the world. in this study, effect of different plant densities were studied on yield and fruit quality of strawberry 'selva' in greenhouse and laboratories of university college of agriculture and natural resources during 2002-2003. uniform stolens of strawberry were planted in holes of plastic column according to factorial in compl...

The current paper summarizes the results of a study aimed at assessing the effectiveness of design for recycling strategies for plastic components. Interviews and site visits were conducted with computer disassemblers and plastics recyclers based in the United States and Europe to investigate the effectiveness of design for recycling guidelines. Both manual and automated recycling technologies ...

Making use of concrete materials in cut-off walls, because of their low permeability and standing high Hydraulic Gradient caused by underground drainage, has attracted great amount of attention. Using ordinary concrete with high elasticity modulus, compared to other materials may accompany with problems including brittleness of cutoffs due to dynamic stresses. To solve this problem, adding a ce...

The quantity of plastic parts in mechanical and electronic industry during past 2-3 decades has a tendency to grow up. Mechatronics systems, in particular, apply many parts of plastic materials. A plastic, which is one of the most versatile materials in the modern age, is widely used because this is an easiest way to get parts of complicated geometrical form and properties. The injection moldin...

The purpose of this paper is to study the behavior of elastic-plastic stresses under severe drag braking. A railway wheel performs three tasks, aiding in trian movement, supporting the car load, and acting as a brake drum. Finite element computer programs are developed for elasto-plastic stress analysis. An attempt is made here to find an improved fillet profile of the wheel with the intention ...

ABSTRACT- To compare the effects of six types of non-living mulches (wheat straw, sawdust, coco peat, peat moss, transparent and black plastic) with metribuzin on yield and yield components of tomato cv "CH" and the weed control efficiency, a study was conducted in a randomized complete block design with three replications at School of Agriculture, Shiraz University in 2012. Plots without mulch...

the aim of this study was to compare and validate the selected methods for estimating fat percentage. for this purpose, 30 inactive female students of shahid rajaei university (age=20.93±1.91; height=164.73±4.57cm; weight=56.65±8.02 kg) were selected voluntarily. they were randomly placed in one of the four different conditions (digital, harpenden, plastic calipers and electrical bioimpedance) ...

The annual American Society of Plastic Surgeons’ “Plastic Surgery: The Meeting” is always filled with great educational events and endeavors, and the 2015 gathering in Boston was truly exceptional. Perhaps the most memorable and most rewarding panel that we had the honor and pleasure to be a part of was the Medical Student Session, moderated by one of the first Plastic and Reconstructive Surger...
