Land leveling is one of the most important steps in soil preparation and cultivation. Although land leveling with machines requires considerable amount of energy, it delivers a suitable surface slope with minimal soil deterioration as well as damage to plants and other organisms in the soil. Notwithstanding, in recent years researchers have tried to reduce fossil fuel consumption and its delete...

Machines are one of the most important production elements used by companies in phase. Sudden deterioration machinery creates a process that can lead to halt and therefore delay orders. For this reason, enterprises decide replace their old machines with newer technological machines. This replacement decision is not easy as it includes many criteria there alternative on market. From point view, ...

Stability is of primary importance for any control systems. Stability of both linear and nonlinear uncertain systems has received a considerable attention in the past decades (see for example, Tanaka & Sugeno, 1992; Tanaka, Ikeda, & Wang, 1996; Feng, Cao, Kees, et al. 1997; Teixeira & Zak, 1999; Lee, Park, & Chen, 2001; Park, Kim, & Park, 2001; Chen, Liu, & Tong, 2006; Lam & Leung, 2007, and re...

The proposed study addresses a two-echelon sustainable supply chain (SC) model with single-vendor and single-buyer by considering the detrimental impacts of environmental pollution due to production. Moreover, an estimation function measure production is developed through separate modelling. In entire chain, we assume deterioration rate increases time it also depends on product’s expiration dat...

abstract seed deterioration of seed is one of the most important limiting or even hindering factors in germination. the main purpose of this study was to determine the effects of salicylic acid and gibberellic acid hormonal on improvement and prevailing seed deterioration in two sesame cultivars. this studywere carried out at the department of agronomy and plant breeding seed laboratories of co...

Ripening and senescence are the ultimate phases in the developmental events of fruits that result in the expression of the quality characteristics inherent to the fruit. Although it is difficult to demarcate a dividing point between ripening and senescence, the former can be designated as the quality-developing phase, whereas the latter predominantly involves the loss of quality. Degradation of...

Milk, which has a very important place in human nutrition, can be harmful terms of health when it is not produced, stored, processed, and necessary controls are performed under hygienic conditions. Even if raw milk contains small number bacteria, degraded short time after the milking by effects microorganisms transmitted from environment various ways constitutes potential source many pathogens ...
