Many rivers originate in high mountainous regions. However, the effects of climate warming on the runoff and water balance in these regions remain unclear due to the lack of observational data from harsh environments, and the variable influences of climate change on alpine land-cover types with different water balances. Using observations and simulations from Coup Model, water-balance values collected at five alpine land-cover types(steppe, shrub meadow, moist meadow, swamp meadow, and moraine) in a small alpine watershed, the Qilian Mountains in Northwest China, from October 2008 to September 2014, were compared. Measured evapotranspiration, multilayer soil temperatures and water contents, and frozen-depth data were used to validate Coup Model outputs. The results show that elevation is the primary influence on precipitation, evapotranspiration, and runoff coefficients in alpine regions. Land-cover types at higher elevations receive more precipitation and have a larger runoff coefficient. Notably, climate warming not only increases evapotranspiration but also particularly increases the evapotranspiration/precipitation ratio due to an upward shift in the optimum elevation of plant species. These factors lead to decrease runoff coefficients in alpine basins.

Objective: Adopting the methods of Evidence-based Medicine research to acquire the dominant prescriptions of Shanghan Zabing Lun in the treatment of Endometriosis, meanwhile to fully dig the value of classical prescriptions. Method: Firstly, we searched and collected the literatures from last three decades in CNKI, Wanfang and VIP databases, which are about classical prescriptions treating endometriosis. Then, by screening all the literatures, we obtained the clinical research literatures and individual case reports. Finally, we went through the internal quality of the two categories of literatures to get the dominant prescriptions. Results: 22 Shanghan Zabing Lun prescriptions have been used in the treatment of endometriosis. According to the clinical research and case literatures, Guizhi Fuling Wan is the prime prescription to treat endometriosis with high quality and high frequency. Conclusions: Through evidence-based medical research and evaluation of evidence, it can be seen that treatment of endometriosis presents a certain tendency that Guizhi Fuling Wan, Wenjing Decoction and Dahuang Zhechong Wan have good clinical effect treating endometriosis and their syndromes are well matched with the symptoms of endometriosis in the present clinical environment.

The possibility of applying steel slag as mineraladmixture in steam-cured concrete was investigated. Thecompressive strength, chloride permeability, carbonationdepth and drying shrinkage of concrete and the microstructurecharacteristics of hardened paste were studied. Results showthat the steam-cured concrete containing steel slag at a highwater-to-binder ratio has low compressive strength, coarsepore structure, moderate permeability, large carbonation depthand great drying shrinkage. The negative effects of steel slagon the mechanical and durability performance of steam-curedconcrete become smaller at a low water-to-binder ratio or byadding ultrafine ground granulated blast furnace slag（UGGBS）. The later-age hydration of cement is significantlypromoted by adding steel slag. The pozzolanic reaction andmicro-filler effect of UGGBS result in dense structure, whichmakes great contribution to the strength development anddurability performance of steam-cured concrete. These effectsof steel slag and UGGBS are significant at a low water tobinder ratio. The steam-cured concrete containing steel slag-UGGBS blended mineral admixture at a low water-to-binderratio has the best performance with high compressive strength,fine pore structure and good durability.

The recently emerged double-cable conjugated polymers have come into focus due to their significantly improved power conversion efficiencies (PCEs) in single-component organic solar cells (SCOSCs). In this work, the effect of chlorination in double-cable conjugated polymers with linear benzodithiophene backbone and pendant perylene bisimide on the photovoltaic performance in SCOSCs has been studied. After introducing chlorine atoms into conjugated side chains, the highest occupied molecular orbital level of the conjugated polymers is down-shifted, thus resulting in a higher open-circuit voltage. As a result, the chlorinated double-cable conjugated polymer exhibits improved photovoltaic performance from 3.46% to 3.57%.
