Hydrology helps determine the character of wetlands; wetlands, in turn, regulate water flow, which influences regional hydrology. To understand these dynamics, we studied the Naoli basin where, from 1954 to 2005, intensive marshland cultivation took place, and the watershed's wetland area declined from 94.4 × 10(4)ha to 17.8 × 10(4)ha. More than 80% of the wetland area loss was due to conversio...

in order to study the effect of intercropping (mix cropping) of three sesame genotypes (sabzevar, kashmar and kalat) a field experiment was conducted based on a complete randomized block design with three replications at research station, college of agriculture ferdowsi university of mashhad, in year 2009. the experimental treatments were: sole cultivation of sabzevar, kalat, kashmar genotypes,...

The agricultural economy of the coastal zone of Queensland and adjacent areas of New South Wales is dominated by sugar production designed for inter-state and overseas export destinations. The modern bulk-cargo terminals which provide shipment facilities at six Queensland sugarports constitute a critical element in a complex system of cultivation, processing, transport and marketing which is cl...

Abstract High biodiversity tends to lead the public, including experts, towards one definite direction, namely conservation. Then came idea of need identify areas with high for Furthermore, any area must be conserved and should not cleared cultivation. However, after being protected, how use public welfare is done immediately, even never. In fact, many conservation have been damaged, some under...

this study investigated the status of mechanized power and self-propelled rice cultivation machinery in guilan province in northern iran. the raw data was obtained from 2013 statistics of the agricultural jihad organization of guilan province. power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

China has limitedly encouraged the talent flow, in which the flow of young talents mainly including the university graduates draws many people's attention. But the recent employment of university graduates is not desirable. The key of this problem lies in the ability of university graduates does not meet the demand of units, so it is necessary now to solve the problem of employability of univer...

Rice, being a major staple crop in South Asia carries its importance in ensuring food security of the region, including in India and Bangladesh. Both the countries have agriculture-based economies where more than 50 percent of the active working population is engaged in agricultural activities. As per UN data, agriculture contributed 17.1 and 18.3 percent, in 2011, in the gross domestic product...

This paper analyzed dynamics of crop diversification in one of the agriculturally prosperous districts of Indian Punjab using Gibbs Martin Index. Spatio-temporal analysis of crop diversification in the district shows decline in crop diversification in most of the blocks (administrative sub divisions). The cropping pattern in most of the blocks of the district has become over specialized in the ...

In this paper we describe several prototypes of self-replicating robotic systems that have been developed at JHU. In contrast to self-reconfiguration, selfreplication is the process of assembling a functional robot from passive components. The robot that is assembled (the replica) is an exact copy of the robot doing the assembling. Our presentation marks the beginning of the JHU effort in this ...
