Climate change impacts on malaria are typically assessed with scenarios for the long-term future. Here we focus instead on the recent past (1970-2003) to address whether warmer temperatures have already increased the incidence of malaria in a highland region of East Africa. Our analyses rely on a new coupled mosquito-human model of malaria, which we use to compare projected disease levels with ...
This article investigated the long-term variation of the boreal summer (JJA) moisture circulation over South China (SC). The total precipitable water (TPW) and moisture convergence over SC have increased obviously, such trend is not a local phenomenon, but the result of large-scale circulation anomaly. In the past few decades, the water vapor transport from southern hemisphere and subtropical w...
Mortality follow-up of two census samples allowed an estimate of socio-economic differentials in mortality for old men, using occupational classes and levels of education reported by individuals when they were active. The study shows persisting mortality differentials after 60 years of age. Over the 1960-65 and 1990-95 periods mortality differentials remained constant between non-manual upper c...
The field of criminology has experienced rapid growth in the last three decades. During this time become institutionally independent, but at same time, impact criminological research on policy been declining face a populist punitive turn. These developments call for reflexive introspective account state discipline. Using qualitative methods, we analyse Presidential Addresses given annual meetin...
Warming-induced drought has widely affected forest dynamics in most places of the northern hemisphere. In this study, we assessed how climate warming has affected Picea crassifolia (Qinghai spruce) forests using tree growth-climate relationships and the normalized difference vegetation index (NDVI) along the Qilian Mountains, northeastern Tibet Plateau (the main range of Picea crassifolia). Bas...

Recent decades have witnessed the growing use of non-native plants in Iran while their use is very challenging and high-cost for the country. This raised a new approach in recent decades towards the use of native plants. Native species are precious because they possess the main ecological factors and they are already compatible with the region. Accordingly, this research was conducted to evalua...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
