BACKGROUND AND AIMS A major challenge in plant ecophysiology is understanding the effects of multiple sub-optimal environmental conditions on plant performance. In most Mediterranean areas soil salinity builds up during the summer because of low availability of soil water coupled with hot temperatures. Although sunlight and soil salinity may strongly interact in determining a plant's performanc...

BACKGROUND: The color of all ceramic restorations has a significant effect on the final appearance restoration. AIM: This study aimed to evaluate different shading techniques stability monolithic zirconia crowns cemented upper anterior teeth. METHODS: In this study, there were nine patients. Each patient undergone reduction for six Fifty-four jacket constructed using CAD/CAM technique. Accordin...

This study was conducted to evaluate the effects of providing shade on growth performance, welfare, and meat quality of grazing sheep under high ambient temperature. A total of 120 healthy male Ujumqin wool sheep (a local breed; BW = 18.7 ± 1.27 kg; 14 wk old) were randomly and equally divided into shaded and unshaded treatments with 3 pens per treatment. Sheep were grazed on an unshaded pastur...

An attractive feature of competitive markets is that they maximize the sum of consumer and producer surplus. Producer and consumer surplus are shown in the market supply and market demand diagram in Figure 7-4. Recall that the producer surplus for all producers is the area above the supply curve and below the market price line, and that the consumer surplus for all consumers is the area below t...

We present an object-space algorithm for global illumination of polygonal scenes containing diiuse area light sources. Our method works within a progressive-reenement radiosity framework. Starting with a minimal scene mesh, we subdivide elements along shadow boundaries and where otherwise needed to capture intensity gradations accurately. Intensities at mesh points are computed by a method that...

Automotive sheet panel strain measurement usually involves large surface areas. For high resolution analysis, using the circle grid analysis method, several hundred elements must be measured. Existing technologies are limited to the small surface that area can be measured in one setup. As well, the (X,Y,Z) location on the part is not accurately available. This paper reports a new surface strain...

Fruit water balance is determined by entry of sap through xylem and phloem, and losses due to back̄ow from fruits to other organs, and to transpiration. The latter, which may vary according to growing and climatic conditions, plays a signi®cant role in fruit water balance. To better understand and predict tomato fruit transpiration, measurements of the transpiration rate of shaded and nonshaded ...
