The need to increase agricultural production has become a challenging task for most countries. Generally, many resource factors affect the deterioration of level, such as low water desertification, soil salinity, on capital, lack equipment, impact export and import crops, fertilizers, pesticide, ineffective role extension services which are significant in this sector. main objective research is...

Abstract In the process of subway operation, braking system is a complex system, and its state detection for high data accuracy positioning According to structure principle method, basic performance parameters are analyzed, combined with abnormal brake cylinder pressure data, divided into two stages: establishment peak stability. And define six characteristic 90% time, special slope period stab...

The relations between language and thought in the normal person, and the connexion between the forms of their disturbance in the dysphasic, are questions which have aroused much discussion and little conclusion. But at least it would seem clear that the nearer an individual's daily occupation approaches to the purely intellectual, the more it is likely to be impeded by even a mild degree of dys...

The province of Quebec, historically known for its unusually high reproductive levels, has in the past few decades experienced a spectacular fertility decline. This more or less abrupt decline in fertility has corresponded with the socioeconomic transformation of this French-speaking province into a modern society. This paper presents a path analysis of period structural factors on fertility ch...

Despite common points in images, the differences put Iran cities in different categories based on deteriorated textures. This classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. F...

Classic theories of ageing consider extrinsic mortality (EM) a major factor in shaping longevity and ageing, yet most studies of functional ageing focus on species with low EM. This bias may cause overestimation of the influence of senescent declines in performance over condition-dependent mortality on demographic processes across taxa. To simultaneously investigate the roles of functional sene...

We suggest that working memory (WM) performance can be conceptualized as the interplay of low-level feature binding processes and top-down control, relating to posterior and frontal brain regions and their interaction in a distributed neural network. We propose that due to age-differential trajectories of posterior and frontal brain regions top-down control processes are not fully mature until ...
