The terrestrial carbon sink provides a critical negative feedback to climate warming, yet large uncertainty exists on its long-term dynamics. Here we combined biosphere models (TBMs) and projections, together with climate-specific land use change, investigate both the trend interannual variability (IAV) of from 1986 2099 under two representative concentration pathways RCP2.6 RCP6.0. results rev...

to evaluate the effects of methanol and drought stress on chlorophyll fluorescence parameters, chlorophyll and relative water content in sugar beet, a study was conducted in 2008 in maahdasht (karaj, iran). aqueous solutions of 0 (control), 7, 14, 21, 28, 35% (v/v) methanol with each solution containing 0.2% glycine and a second factor, namely drought stress (irrigation after 70% depletion of a...

The increasing frequency of large, high-severity fires threatens the survival of old-growth specialist fauna in fire-prone forests. Within topographically diverse montane forests, areas that experience less severe or fewer fires compared with those prevailing in the landscape may present unique resource opportunities enabling old-growth specialist fauna to survive. Statistical landscape models ...

We have previously demonstrated that DT-010, a novel conjugate of danshensu (DSS) and tetramethylpyrazine (TMP), displays anti-tumor effects in breast cancer cells both in vitro and in vivo. In the present study, we investigated whether DT-010 enhances the chemotherapeutic effect of doxorubicin (Dox) in MCF-7 breast cancer cells and exerts concurrent cardioprotective benefit at the same time. O...

Census data from 1991 from Botswana and Namibia were analyzed using the ‘children ever born technique’ to estimate child mortality. The method used is reviewed briefly, with emphasis on aspects not covered by the standard UN reference on mortality estimation, Manual X. The census data appear to be of very high quality for use with the children ever born technique. Between the mid-1970s and the ...

OBJECTIVE Lead exposure has been associated with intellectual impairment in children in a number of international studies. Prevalence of elevated blood lead levels (eBLL > or = 10ug/dL) of between 5 - 15% has been reported among in Nairobi (UNEP, 2006). However, little is known about potential environmental exposure for eBLLs among children in Kibera, Nairobi. METHODS A descriptive, cross-sec...

The Himalayan and Tibetan Plateau (TP) region serves as the “Asian water tower”. Yarlung Zangbo basin (YZB) is one of most important major rivers originating from TP sustaining billions lives in downstream alluvial plain. Climate change has impacted hydrological cycle this alpine region; however, temporal spatial trends runoff balance not been quantified adequately. Here, we have optimized snow...

since the rate of return on different opportunities for investment is random, the optimal distribution of ones capital is put foreward as a stochastic control problem. in this paper, using modem techniques in the theory of random functions and the stochsatic calculus, the problem is discussed for the case when the information possessed by the different investors, as well as their probability be...

Pakistan is one of the most highly water-stressed countries in the world and its water resources are greatly vulnerable to changing climatic conditions. The present study investigates the possible impacts of climate change on the water resources of the Kunhar River basin, Pakistan, under A2 and B2 scenarios of HadCM3, a global climate model. After successful development of the hydrological mode...
