Schistosomiasis mansoni, known colloquially as bilharzia, came to Puerto Rico with the slave trade [1-3]. At the beginning of the 20th century, schistosomiasis was limited to several low-prevalence locations in Puerto Rico (Mayaguez, Utuado and Aibonito) and the adjacent island of Vieques an area of high prevalence. The change from a coffee economy (that was precipitated in part by Hurricane Sa...

Agarwood is a kind of important and precious traditional Chinese medicine. With the decreasing of natural agarwood, artificial cultivation has become more and more important in recent years. Quantifying the formation of agarwood is an essential work which could provide information for guiding cultivation and controlling quality. But people only can judge the amount of agarwood qualitatively by ...

Agriculture has two ways to increase its output, expanding the land area under cultivation and improving the yields on cultivated land. If agricultural growth and performance taken to increase the farming incomes of rural families, then a third way can be added, i.e. shifting the product composition to higher value products. For decades, it has been commented that, globally the possibilities fo...

The Imam Khomeini sugarcane agro-industry is one of ten sugarcane agro-industry plantations in Khuzestan province. As regard as the drains has been installed  in this plantation many years ago so there is water and salt balance in this land that is one of the condition for implementation controlled drainage. This research was designed to investigate the possibility of using a controlled drainag...

Weather and climatic parameters and their impact on farming plants are one of the foremost effective factors on improvement of crop yield. The potential facilities of various regions may be determined with agroclimatic study and exploit maximally from these facilities. In order to evaluate agroclimate of colza cultivation throughout the selected substations at Hamedan Province in this current i...

Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and discriminate among 17 unknown genotypes (considered potentially salt tolerant) and 16 known olive cultivars. Fifteen decamer primers which produced 38 reproducible polymorphic bands in the genotypes were selected for analysis. The RAPD markers resulted in 93 distinct banding patterns. Based on either ...
