Background and purpose: Industrial effluent and sewage sludge are used as fertilizer since they contain high levels of nutrient. The main pollutant in industrial effluent is heavy metals. In this study an assessment was made on the impact of industrial wastewater effluent and sewage sludge on accumulation of heavy metals in agricultural soil at Agh ghallah industrial Estate. Materials and meth...
This paper studies the effects of rural infrastructure development on agricultural production technical efficiency, using data from the second agricultural census of China. Employing Data Envelopment Analysis, this paper first estimates agricultural production technical efficiency of each administrative area of China. A Tobit model is then applied to study the effects on agricultural production...
soil contamination significantly reduces environmental quality and affects human health. to investigate and assess the effects of land use on the concentrations of some heavy metals in surface soils of golestan province, 227 soil samples (0-60 cm) were collected from three types of land uses including agricultural lands, natural, and industrial areas. the total metals and metalloids (cr, se, as...
The grain procurement and marketing system was established in China in the early 1950s. The primary policy objective was to ensure equal and relatively efficient distribution of limited grain among consumers and industrial users, and to ensure the growth of grain production at the planned rate. At the same time, it was assigned another important task: to divert agricultural surplus into investm...
The industrial robotics is the ideal technology platform to build the foundations for a significant innovation in production systems. In fact, industrial robots combine high flexibility and adaptability, effective (re)configurability at batch change, easiness and speed of programming, operation robustness and complete integration with advanced technology in the field of mechanics, information t...
New Social Structures Are Generating New Leadership Styles Different epochs produce different kinds of leadership – with different patterns of hierarchical authority, different skill sets and attitudes, and different institutional incentives. Societies today are experiencing significant changes potentially as far reaching as the transition from agricultural to industrial societies. Today’s epoc...
Most of the interfaces which are designed to control or program industrial robots are complex and require special training for the user. This complexity alongside the changing environment of small medium enterprises (SMEs) has lead to absence of robots from SMEs. The costs of (re)programming the robots and (re)training the robot users exceed initial costs of installation. In order to solve this...
There are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of China lands which are facing serious problem of desertification. Theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofNortheast China, North central china and most of northwest china. Biological methods are theultimate way for drift sand stabilization and a fu...
