abstract there is not much sources about ancient carnival and ceremonies , but some information can be gain from documents . as a matter of fact the ceremonies were a part of zarartiyan principles which zartosht had taken them to his religion . it should be mentioned that the oldest ceremonies are about poster and agriculture principles this seasonal ceremonies were very important for agri...
Changes of land use/land cover have a significant impact on runoff by altering the surface evaporation, soil moisture conditions and the amount of trapped ground cover, which directly impact the sustainable development of the watershed ecology. In this paper, based on remote sensing images, we simulate runoff of land-use changes of different slopes using GIS technology and SWAT model in Erhai w...
Ants are known to function as reliable biological indicators for habitat impact assessment. They play a wide range of ecological roles depending on their feeding and nesting habits. By clustering ants in guilds, it is possible both to assess how agriculture and forest fragmentation can disturb ant communities and to predict the ecological impacts due to losses of a specific guild. This study ai...

An improved understanding of the ecology of fleas on California ground squirrels, Otospermophilus beecheyi, is warranted given the role of fleas in the transmission, and perhaps persistence, of the plague-causing bacterium Yersinia pestis. We sampled O. beecheyi on a seasonal basis from three study sites, each representing a different land use type (preserve, pasture, and agriculture) in the Sa...
one of the main resonator factors in watershed soil erosion is inappropriateland management including conversion of pasture land to dry-land farming.unfortunately, the changes of gara su watershed usages have been very common.thus, in order to understand the influence of land use on runoff rate and soil loss, soillosses were investigated and determined under both pasture and dry-land agricultur...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
