Objective:To investigate the anti-inflammatory and analgesic effects of Solanum procumbens on complete Freund’s adjuvantinduced arthritis rat ***:We isolated and identified five compounds in the ethanolsoluble Solanum procumbens extract(SP)with anti-inflammatory effects,including ursolic acid,β-sitosterol,hexadecanoic acid,cisvaccenic acid,and vanillic ***,we investigated the anti-inflammatory effects of SP on rheumatoid arthritis symptoms,including paw volumes,local temperatures,withdrawal latency,and mechanical withdrawal threshold at the hind paw and white blood cell(WBC)number from complete Freund’s adjuvant-induced arthritis rat ***:We have successfully established a complete Freund’s adjuvant-induced arthritis rat model at a low dose(1 mg/mL).SP extract significantly reduced paw volumes(P<0.05),prolonged withdrawal latencies(P<0.05),decreased local temperature,and increased the mechanical withdrawal threshold(P<0.05),but only SP extract at the dose of 300 mg/kg significantly decreased WBC ***:SP extract could be a potential medication candidate with anti-inflammatory effects for arthritis,but it requires further investigation into the mechanism of the SP and its effectiveness on other models as well as clinical trials.

This study investigated the effect of installing underwater light-emitting diode(LED)lights in different locations(close and distant to the trap entrance)and orientations(normal and upside down direction)inside baited traps targeting snow crab(Chionoecetes opilio)off the coast of Newfoundland and Labrador,*** experimental treatments were evaluated in comparison with traditional baited traps(control).Our results showed each of the experimental treatments produced significantly higher(39%–57%;48%on average)catch per unit effort(CPUE)compared to the control traps,with no significant differences for both legal and sublegal-sized crab among the different experimental *** soak times significantly increased the CPUE of the illuminated traps,but did not affect the catch rate of the control *** results also indicated crab size frequency distributions were independent of experiment *** results suggest that fishing enterprises could improve their catching performance by adding LED lights to their traps,but the location and orientation of the lights appears unimportant.

This study investigated the behaviour and commercial catchability of snow crab(Chionoecetes opilio)in response to different low-powered LED lights under laboratory and field *** created a novel choice-experiment in a laboratory setting in which we investigated the behaviour of snow crab in response to coloured LED *** results showed that snow crab movement was dependent on light colour,with animals choosing to move toward blue and white lights,away from purple lights,and no detectable effect for green and red *** then conducted two field experiments to investigate the effect of the same LED lights on the catch rates of commercial traps during the 2016 snow crab fishery on the east coast of Newfoundland and *** from the first field experiment showed that adding white and purple LED lights into baited traps significantly improved Catch Per Unit Effort(CPUE)by 77% and 47% *** from the second field experiment showed that unbaited traps equipped with only LED lights(no bait),could also catch snow crab in comparable amounts to traditional baited traps,with soak time and depth explaining some of the variation in *** together,these experiments suggest that fishing enterprises can improve their catching performance and profitability by adding LED lights to their traps,or by using LED lights as a bait replacement.

激进女性主义将运动中性别不平等的根源视为父权制的结果。激进女性主义在体育领域对父权制的批判,主要集中在父权制暗含的男性身体优越性、父权制下的体育权力机构以及女性体育的男性中心取向等3个方面。激进女性主义认为,性别气质是社会建构的结果,并且可以通过运动予以解构和重建;女性对男性传统体育项目的参与挑战了传统的性别理解,同时,男性参与女性传统项目对于其人格的完整发展也是有益的。从本质上讲,激进女性主义所运用的是一种文化分析的方法,其力图通过对运动意义和流行方式的重新界定来实现实质性的性别平等。

Spatio-Temporal Determination of Irrigated Paddy Rice Pixels Using Evapotranspiration and Vegetation Indices: A Case Study for Ca River Basin in Vietnam

Nguyen Institute of Water Resources Planning Hoan Kiem Hanoi Vietnam Division of Water Resources Planning in Northern Central Region Institute of Water Resources Planning Hoan Kiem Hanoi Vietnam Department of Training and International Cooperation Institute of Water Resources Planning Hoan Kiem Hanoi Vietnam Division of Hydro-Meteorology Institute of Water Resources Planning Hoan Kiem Hanoi Vietnam

Improving irrigation monitoring and efficiency is a current priority of the Government of Vietnam, focusing primarily on the agricultural sector which consumes most of the available surface and groundwater. This paper presents how remote sensing can be used in an integrated manner to achieve better understanding of key eco-hydrological processes including precipitation, evapotran-spiration, irrigation and crop growth. The results indicated that Normalized Difference Vegetation Index derived from Moderate Resolution Imaging Spectroradiometer (MODIS) can be applied to determine irrigated pixels on a spatial and temporal basis. The validation using measured water level showed a Pearson correlation of 0.7 proving the high accuracy of this method. The inclusion of these technologies is deemed necessary to improve water resources monitoring and management and hence, ensure long-term drought resilience and water and food security. Ca River Basin in the central Vietnam was selected as a case study to test this approach.

以邢衡高速公路一期工程为例,采用数值模拟的方法,对高速公路路基下刚柔性长短桩复合地基的桩土应力比和沉降变形的变化规律进行了研究。研究结果表明:桩间距、柔性桩桩长、下卧层土体变形模量对桩土应力比的影响较小,适当提高柔性短桩变形模量可增加柔性短桩的荷载分担比;适当减小桩间距和提高柔性短桩变形模量可在一定程度上减小路基的沉降变形;下卧层土体的变形模量对路基的沉降变形影响较大。
