Yield prediction before harvesting is one of the tools in order to planning food production supply in future.Yield prediction was carried out for Wheat(Triticum aestivum) using different meteorological variables with agrometeorological indices in Hamedan district during 2003-04 and 2004-05. According to correlation coefficients, standard error of estimate as well as relative deviation of predic...

PURPOSE The purpose of this prospective study was to evaluate the safety of zygomatic bone harvesting and to determine whether a particulated zygomatic bone graft can be used simultaneously with 1-stage dental implants to reconstruct resorbed edentulous alveolar ridges. MATERIALS AND METHODS Altogether, 82 dental implants were placed in 32 patients. Particulated bone grafts harvested from the...

Artificial rainwater harvesting system (ARHS) is a new way to increase water supply in semi-arid area, and has developed rapidly recent years in northwestern China. Not only it used in domestic supply, but also in agricultural as supply irrigation. More than 2 million water cellars have been built in Loess Plateau of China. In this paper, based on 5 years’ related experiments, field engineering...

The growing popularity of solid state thermoelectric devices in cooling applications has sparked an increasing diversity of thermoelectric coolers (TECs) on the market, commonly known as “Peltier modules”. They can also be used as generators, converting a temperature difference into electric power, and opportunities are plentiful to make use of these devices as thermoelectric generators (TEGs) ...

in this research, the accelerated ripening of the kabkab dates from khalal to tamr using nacl and acetic acid solutions was studied. fruits at khalal stage were harvested and washed with distilled water before being treated with ripening inducers: 1. nacl solutions, 2. acetic acid solutions and 3. aqueous solution of nacl (1%) and acetic acid. moisture, ph, colour, brix and textural firmness of...

Gnathostoma spinigerum third stage larvae antigen is necessary for Western blot analysis in the diagnosis of Gnathostomiasis. Acid pepsin solution is required for digestion of eel's liver( Fluta alba ) to yield the larvae for antigen preparation. Here, he reported the feasibility of using orange juice as an alternative to enzyme pepsin in harvesting Gnathostoma spinigerum third stage larvae. Fr...

This article presents a dual-frequency (DF) dual-input-dual-output interface based on reconfigurable switching converter for thermoelectric energy harvesting. The DF operation decouples the rate of extraction at input stage from distribution output stage. automatically makes transitions among two energy-harvesting modes and one energy-recycling mode according to load condition. low-frequency ha...

Background: The leaves, roots and seeds of Lovage (Levisticum officinale Koch) being used as an herb, vegetable and spice. Objective: The aim of this study is evaluation of the changes of phytochemical compound in aerial parts of the Lovage plants at different developmental stages as well as antioxidant activity. Methods: The plants were harvested from Hezar Mountain. After drying, essent...

Recommended by Xue-Zhong He We consider a periodic time-dependent predator-prey system with stage structure and impulsive harvesting, in which the prey has a life history that takes them through two stages, immature and mature. A set of sufficient and necessary conditions which guarantee the permanence of the system is obtained. Finally, we give a brief discussion of our results.
