作为非营利组织的协会，因其运营的特殊性，使得协会的管理者们常常面临困局。在最近一项对近1000名协会领导人的调查中，当被问到“未来一年发展组织的最大挑战是什么”时，最常见的回答是缺乏资源。“缺乏资源”很可能意味着缺乏足够的工作人员或者缺乏足够的资金。但是如果可以有效利用，会员就是多数协会的最大资源，这是需要最大化利用的资源。

Open Journal of Modern Hydrology 2014年第4期4卷 121-131页

Until the late 1950s the Hula Valley, located between altitude of 170 masl in the northern part and 61 masl in the southern part, was covered by the old shallow Lake Hula (1.5 m mean depth;1400 ha water surface);and 4500 ha of swamps partly or permanently were water covered. During 1950-1957 the old Lake Hula and the wetlands were drained and converted into agricultural usage. As a result of inappropriate agricultural management, a reclamation project (Hula Project, HP, 1990-1997) was implemented. A vertical plastic sheet (4.5 m deep) was placed along 2.8 km across the valley aimed at reduction of pollutants migration. This plastic barrier divided the valley into northern, organic, and southern mineral soil blocks. The HP was aimed at agricultural renovation together with prevention of water quality deterioration in the downstream Lake Kinneret. The chemical composition of the underground waters was monitored on a monthly basis in 14 drills and ground water table observation wells over the valley during 14 months. The Ground Water Table (GWT) in the northern part of the valley was shallower than in the south and seasonal fluctuation amplitudes were smaller in the north. Higher levels of TP, TDP, P-Ortho and particulate Phosphorus, TN and ammonium were documented in the southern underground waters. The level of nutrient concentrations in the south was probably enhanced by three factors: 1) accumulation by underground water migration;2) eroded substances from the southern mineral soil;3) intensive Evapo-Transpiration in the south. Due to the lower level of organic content in the south and in spite of possible underground accumulation no significant difference between southern and northern blocks was indicated for Nitrate (NO3) concentrations. Not like nitrates, the reduced nitrogen form of ammonium concentration in the undergrounds was higher in the south. It was suggested that the nutrient concentrations (dissolved and suspended) in the Southern underground waters we

Platelet-free plasma of human blood (sodium citrate and EDTA as an anticoagulant) and serum were stored at 4°C, room temperature (25°C) and at 37°C for 24 hours. RBC aggregation decreased after incubation of plasma and serum at 37°C for 4 hours. The RBC shape was changed at the same time: discocytes transformed to echinocytes. Storage of plasma and serum at 4°C and room temperature did not lead to significant alterations of RBC aggregation. The RBC shape did not change in influence of such plasma and serum. The most considerable decrease of RBC aggregation and change of their shapes were observed in the plasma and serum incubated at 37°C for 24 hours. Dilution of incubated plasma by fresh plasma led to consistent restoration of erythrocyte shape and their aggregation.

The low-temperature measurement of Hall effect of the two-dimensional electron system in a double-layered gated Si-δ-doped GaAs is presented.A complex peculiar nonlinear dependence of the depletion on gate voltage is *** nonlinearity is also explained on the basis of the assumption that the double-capacity model consists of two δ-doped two-dimensional electron layers and a metallic gate,and the experimental result that the electron mobility is linear with the electron density on a log-log scale.

河南偃师灰嘴遗址包含有仰韶中晚期、龙山中晚期、二里头时期及东周时期遗存。该遗址在龙山和二里头时期发展成为石器制造中心,在伊洛地区史前时期社会复杂化发展进程中扮演了重要角色。为了进一步了解各个时期的生计结构,我们对灰嘴出土的28件切割工具(刀、镰和矛)进行了微痕、淀粉粒和植硅体的综合分析。分析结果说明,刀和镰主要是用来收割栽培谷物,包括粟黍、薏苡、小麦族和稻谷,但也收获或加工其他植物,如大豆和多种块根类植物,如山药、百合科、栝楼根等。结合浮选结果进行综合性分析,可知先民在灰嘴居住的两千多年历史中的生计形态变化表现为:仰韶时期是以粟黍-薏苡为主,到龙山、二里头时期逐渐转变为以粟黍-薏苡-麦类-大豆为主,同时始终以稻米和多种块根植物为辅。
