At present, many researchers concentrate on the researches of sink mobility and propose a lot of efficient data harvesting algorithms for wireless sensor networks (WSNs). In general, these algorithms mainly formulate their ideas in two ways, namely path-controllable and path-constrained sink mobility. In most application scenarios of WSNs, mobile sink is path-constrained and a big challenge of ...

With introduction of social niche effects into a model of cultural change, the frequency of a practice cannot predict the frequency of its underlying belief. The combination of a general model with empirical data from a specific case illustrates the importance of collaboration between modellers and field researchers, and identifies the type of quantitative data necessary for analysing case stud...

in order to investigate the effects of nitrogen application rates and different planting beds on yield and yield components of garlic (allium sativum l.), a field experiment was conducted as split plot based on a randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, iran, during 2009-2010. three nitrogen application rates ...

access to development and life quality improvement are ideals that all the time has involved human’s mind. nowadays development phenomenon besides economic programs contains cultural and social subject. one of the important subjects in development part is women's issues. in these days, even though trend to women's issues in new approaches of development has increased, but in many coun...

How can the differing levels of voter participation in sub-national parliamentary elections be explained? To answer this question I start from the current literature on cross-national comparative research, and apply explanatory approaches from this literature to the analysis of electoral turnout in sub-national units. I focus on two competing influential assessments in the literature, instituti...

nowadays, adolescent girls live in such a more complex and challengeable world that considering their infinite desires and potential abilities as social, cultural, economical and geographical conditions change their needs and social inclinations become more diverse and dynamic. this study probes into the social, cultural, and educational needs of adolescent girls studying at junior high school ...
