To date, few reports have been concerned with the physical properties of the liquid phases of imidazoles and benzimidazoles- potential starting materials for a great number of ionic liquids. Prior research has indicated that alkylimidazole solvents exhibit different, and potentially advantageous physical properties, when compared to corresponding imidazolium-based ionic liquids. Given that even the most fundamental physical properties of alkylimidazole solvents have only recently been reported, there is still a lack of data for other relevant imidazole derivatives, including benzimidazoles. In this work, we have synthesized a se- ries of eight 1-n-alkylbenzimidazoles, with chain lengths ranging from ethyl to dodecyl, all of which exist as neat liquids at ambient temperature. Their densities and viscosities have been determined as functions of both temperature and molecular weight. Alkylbenzimidazoles have been found to exhibit viscosities that are more similar to imidazolium-based ILs than al- kylimidazoles, owed to a large contribution to viscosity from the presence of a fused ring system. Solubilities of CO2 and SO2, two species of concern in the emission of coal-fired power generation, were determined for selected alkylbenzimidazoles to understand what effects a fused ring system might have on gas solubility. For both gases, alkylbenzimidazoles were deter- mined to experience physical, non-chemically reactive, interactions. The solubility of CO2 in alkylbenzimidazoles is 10%-30% less than observed for corresponding ILs and alkylimidazoles. 1-butylbenzimidazole was found to readily absorb at least 0.333 gram SO2 per gram at low pressure and ambient temperature, which could be readily desorbed under an N： flush, a behavior more similar to imidazolium-based ILs than alkylimidazoles. Thus, we find that as solvents for gas separations, benzimidazoles share characteristics with both ILs and alkylimidazoles.

This study investigated carcass characteristics of guinea fowl reared under intensive system and fed diets containing yellow maize, millet and white sorghum as energy sources compared to commercial broiler diets (control). A completely randomized design was used where 160 guinea fowl keets were randomly assigned to four dietary treatments. Data were analyzed using Procedure General Linear Model in Statistical Analysis Software (version 9.0). Results showed that dietary treatment did not (p > 0.05) influence carcass characteristics of guinea fowl at the same age. However, carcass characteristics significantly (p < 0.05) increased with age. From 6 to 16 weeks of age carcass dressed weight of guinea fowl increased from 301.73 ± 9.49 g to 1003.65 ± 26.77 g;288.18 ± 9.49 g to 952.58 ± 26.77 g;305.00 ± 9.49 g to 976.55 ± 26.77 and 292.81 ± 9.49 g to 970.08 ± 26.77 g for control, maize, millet and sorghum diets, respectively. Carcass yield slightly increased from 69.93% ± 3.67% to 72.81% ± 2.67%;73.85% ± 3.67% to 76.31% ± 2.67% and 70.55% ± 3.67% to 72.37% ± 2.67% for control, millet and sorghum diets, respectively. Carcass yield of guinea fowl on maize diet decreased with age (76.18 ± 3.67 to 71.68 ± 2.67). Other parameters including empty gizzard, heart, liver, drumstick, thigh, back and breast increased with guinea fowl age for all the dietary treatments. Maize, sorghum or millet diets can be used in guinea fowl diets without affecting carcass characteristics. Further studies on the acceptance of meat by consumers and cost-benefit analysis of the dietary treatments should be conducted to enable formulation of guinea fowl diets using local feed resources.

本文从放电靶电流出发,采用一种新的研究方法,即将靶电流分解为多个代表具体放电特性的特征参数,全面而系统的研究了不同的工作气压条件下,靶电流各特征参数随靶电压的增加而进行的演化.结果发现高功率脉冲磁控溅射技术(HPPMS)放电靶电流在靶电压由低向高增加的过程中,出现靶电流峰值和平台值的交替变化,体现出明显的阶段性放电特征,且不同的放电阶段在不同气压下出现一定的移动,会在测量范围内出现某些放电阶段的缺失.本文还通过等离子体发射光谱对HPPMS放电靶前等离子体测量发现五个不同的放电阶段分别主要对应氩原子、铬原子、氩离子、铬离子和氩、铬高价离子的放电,但不同的放电条件下相邻的阶段会出现一定程度的交叠.

聚合物导电性能差,表面电荷积聚所产生的电容效应致使其表面电位衰减,采用等离子体浸没离子注入对其表面改性是非常困难的.建立了绝缘材料等离子体浸没离子注入过程的粒子模拟(PIC)模型,实时跟踪离子在等离子体鞘层中的运动形态及特性并进行统计分析.并基于PIC模型,将聚合物表面的二次电子发射系数直接与离子注入即时能量建立关联,研究了聚合物厚度、介电常数和二次电子发射系数等物理量对鞘层演化、离子注入能量和剂量的影响规律.研究结果表明:当聚合物厚度小于200μm,相对介电常数大于7,二次电子发射系数小于0.5时,离子注入剂量和高能离子所占的份额与导体离子注入情况相当.通过对聚合物表面离子注入剂量和高能离子所占份额的研究,为绝缘材料和半导体材料表面等离子体浸没离子注入的实现提供了理论和实验依据.

Journal of Computer and Communications 2014年第2期2卷 85-90页

作者： ricky Timothy Gultom Maya Retno Ayu Setyautami Iis Solichah Faculty of Computer Science Universitas Indonesia Depok Indonesia.

This article contains a system conversion from object oriented design into Software Product Line (SPL) using delta modeling of Abstract Behavioral Specification (ABS). ABS is a modeling language which targets system with high level of variety and supports SPL development with delta modeling. The case study of this thesis is a digital library system called Library Automation and Digital Archive (LONTAR). Originally, LONTAR only uses SOAP-based web service. With ABS, LONTAR will be converted into SPL and implement another web service called REST. The motivation of this conversion of LONTAR from object oriented into SPL is because it is easier to develop system with ABS than using regular object oriented. Product definition in ABS is relatively easier than creating a new subclass and do customization to make it works well.
