This study aims to compare the performance of two hydrological models, conceptual (HEC-HmS) and spatial (ATHYS) on the Aguibat Ezziar watershed. The comparative analysis is based on the performances of simulation in terms of Nash-Sutcliffe and RSR. The study requires the collection of a series of data as inputs models namely rainfall data, water quantity, soil occupation, DTm and requires also a calibration in order to evaluate these models in validation phase. The simulation results were obtained from the validation phase aiming to replicate the operation of watershed Aguibat Ezziar, and present a suitable adjustment perspective of the observed hydrograph. These results show that the objective is achieved and a model distributed like ATHYS plays an effective role to improve the efficiency and present a high advantage in anticipation of runoff volume comparing with other models.

Fuel ethanol is an important renewable and sustainable fuel, produced in China by fermentation of mostly corn, wheat and cassava feedstock. Fermentation produces an ethanol-lean broth (10 to 12 vol%). Ethanol is recovered by distillation, followed by a molecular sieve drying beyond the azeo-tropic point. The distillation and molecular sieve operations consume most of the total energy used, with the steam consumption currently being ~1.8 kg/kg ethanol, including 0.5 kg/kg ethanol in the final molecular sieve stage during regeneration. The objectives of the paper are fourfold: 1) firstly to study the distillation process of a large-scale cassava-based fuel ethanol production (200,000 tons per year), by field measurements and by using an Aspen Plus V8.2 simulation, with and without energy integration of condensers and reboilers, resulting in a distillation steam consumption of ~1.3 kg/kg ethanol;2) secondly, to examine the effects of using Very High Gravity (VHG) fer-mentation of cassava meal mash. By using VHG fermentation, the ethanol concentration in the fermenter broth is significantly increased, to about 19 vol% (15.4 wt%). The steam consumption is then reduced to ~0.94 kg/kg, representing a considerable saving in comparison with the current operation. Applying VHG fermentation needs minor additional investment, rapidly recovered through the energy savings and the smaller size of equipment;3) thirdly, to assess the application of a hybrid operation, where pervaporation will be used to selectively and continuously remove ethanol from the fermenter broth, thus slightly increasing the fermentation yield by reducing the risk of ethanol inhibition, whilst producing an ehtanol-rich permeate (about 30 wt%);and finally 4) to demonstrate that the production cost of cassava-based ethanol can substantially be reduced by applying the proposed improvements.

孔隙度—强度相关性：通过孔隙度测井资料获取破裂判据

An important source of revenues for Channel 4 comes from the campaign advertisement during commercial breaks. Given a set of campaigns(TV advertisements) and a set of breaks with air times, the Campaign Allocation Problem(CAP) is to determine how campaigns’ spots should be allocated to a subset of breaks in order to maximize total revenue and evenness with respect to all business rules and constraints.

使用移动电话引发脑部紊乱症状的报道正在增加 ,而且 Hockingc对此也有过描述。有人也收集到一系列这类病例 ,但尚未公开发表。这类病例的许多症状特征是头晕、定向力障碍、恶心、头痛和短暂性意识模糊。可预测这些症状是因前庭器官单侧刺激而引起 ,这些症状的发生是由辐射波对半规管内淋巴 (内耳膜迷路内的液体 )或毛细胞直接作用而导致 ,或因移动电话发热外耳道对流增高而产生这些症状。大多数患者陈诉耳周围有发热的感觉 ,常常伴有皮肤变红。Blanks等人指出 ,半规管的精确定位有明显的变化 ,其可导致某些人对较大热量刺激的一种偏受。由于常在喧闹的环境中使用移动电话 ,使用者持用此种工具时比普通电话更紧贴在耳朵上。本文作者有理的推测和临床证据支持这种假设 :某些人有前庭器官的短暂症状 ,与他们使用移动电话有关 ,可能占 5%～8%的移动电话使用者。本文作者还认为这种假设应做试验检测 ,因为移动电话在增加某些人患病的同时 ,移动电话的使用亦在增加。通过试验进一步确定这种假设也是重要的 ,以寻找定向障碍潜在的不明确症状的机理 ,以及强调这些症状未显示出对发生脑瘤有任何较大的危险性 ,最终要说明移动电话对脑瘤有还是没有任何关...
