Protective clothing for pesticide operators: part I – selection of a reference test chemical for penetration testing

A systematic approach was taken to develop a database for protective clothing for pesticide operators; results are reported as a two-part series. Part I describes the research studies that led to identification of a pesticide formulation that could serve as a reference test chemical for further testing. Measurement of pesticide penetration was conducted using different types of pesticide formulations. Six fabrics were tested using 10 formulations at different concentrations. Three formulations were subsequently selected for further testing. Analysis of the data indicated that, when compared with other formulations, mean percent penetration of 5% Prowl 3.3 EC [emulsifiable concentrate diluted to 5% active ingredient (pendimethalin)] is either similar to or higher than most test chemicals. Those results led to choosing 5% Prowl 3.3 EC as a reference test liquid. Part II of the study, published as a separate paper, includes data on a wide range of textile materials.     

When the dark ones become darker: How promotion focus moderates the effects of the dark triad on supervisor performance ratings

The current study adds to a growing body of research on dark personality traits by investigating the moderating role of promotion focus on the relationships among dark triad traits and facets of job performance. Specifically, we investigated the effects of the dark triad (i.e., Machiavellianism, narcissism, and psychopathy) on supervisor ratings of performance, and the moderating effect promotion focus has on those effects. Using field data, we surveyed 549 employees from a manufacturing company in the USA and obtained supervisor ratings of task performance and helping behavior for each employee. We found support for multiple hypotheses, which suggests that managers rated narcissistic and psychopathic employees as having poorer task performance and psychopathic employees as engaging in fewer helping behaviors than employees low in those traits. Furthermore, promotion focus strengthened these negative relationships. We did not find these effects for Machiavellianism. Implications of these findings for future dark personality research as well as the practical implications for managers and organizations are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Energy's role in the extraversion (dis)advantage: How energy ties and task conflict help clarify the relationship between extraversion and proactive performance

While academic and practitioner literatures have proposed that extraverts are at an advantage in team‐based work, it remains unclear exactly what that advantage might be, how extraverts attain such an advantage, and under which conditions. Theory highlighting the importance of energy in the coordination of team efforts helps to answer these questions. We propose that extraverted individuals are able to develop more energizing relationships with their teammates and as a result are seen as proactively contributing to their team. However, problems in coordination (i.e., team task conflict) can reverse this extraversion advantage. We studied 27 project‐based teams at their formation, peak performance, and after disbandment. Results suggest that when team task conflict is low, extraverts energize their teammates and are viewed by others as proactively contributing to the team. However, when team task conflict is high, extraverts develop energizing relationships with fewer of their teammates and are not viewed as proactively contributing to the team. Our findings regarding energizing relationships and team task conflict clarify why extraversion is related to proactive performance and in what way, how, and when extraverts may be at a (dis)advantage in team‐based work.

基于投影寻踪的资源环境综合绩效评估方法研究

资源环境综合绩效评估是建设节约型社会的一项基础工作.在传统的资源环境综合绩效指数中,各种资源消耗和污染物排放绩效的权重相等,导致综合评价结果的合理性受到影响.针对该问题,通过构建投影指标函数和采用遗传算法对投影方向进行优化,提出了基于投影寻踪的资源环境综合绩效评估方法,并应用于2007年中国各省、直辖市和自治区的资源环境绩效评估.研究结果表明,中国资源环境绩效水平空间差异明显,呈现东部高西部低的特征,因此必须合理调整西部地区的经济结构,提高资源利用效率和加强环境保护,实现可持续发展.该方法的权重取值较为客观和科学,评估结果合理,值得推广应用.     

中原经济区城市资源环境绩效指标体系构建与实证

为了识别城市或“相似群体”最重要的资源环境“短板”问题,以中原经济区31个城市为研究区域,选择水土资源、能源、环境质量和污染物排放及治理水平等4个方面共计33项指标,利用层次分析修正法确定指标权重,采用正向指标极大化、负向指标极小化、适中指标平均化的标准化方法对研究区域内各市资源环境绩效进行测算. 研究表明:①从资源环境绩效角度来看,中原经济区城市可分为“双高”超载型、农业型、“双低”超载型、资源型四大类. ②占中原经济区城市总数2/5的资源型城市,由于过度强调资源产出、忽视环境保护而成为经济区环境问题高发、资源环境矛盾较为突出的集中区域. ③在对4个Ⅰ级指标(资源利用效率、能源利用效率、环境质量指数、污染物排放及治理水平)设定均衡权重情况下,15个城市的能源利用效率居末位,10个城市的资源利用效率居末位,表明中原经济区提高资源环境绩效应率先在能源、资源利用效率领域实现突破. 所构建的资源环境绩效评估指标体系仍有待进一步优化,今后应加大对可再生资源能源利用、农村生态环境特别是农村土地重金属及有机物污染等问题的关注.      

Impact of various blends of Mimusops elengi methyl esters on performance and emission characteristics of a diesel engine

The basic objective of the research work was to study the effect of various blends of Mimusops elangi methyl ester (MEME) on engine performance, combustion, and emission characteristics of a single-cylinder direct-injection compression ignition engine, running at constant speed. The raw oil was extracted from Mimusops elangi seeds through mechanical crusher. The neat MEME was obtained through transesterification process and mixed with diesel in versatile proportions of 10% of MEME (10% MEME–90% Diesel), 20% of MEME(20% MEME–80% Diesel), 30% of MEME(30% MEME–70% Diesel), 40% of MEME(40% MEME–60% Diesel), and 100% MEME on a volume basis. Their properties were validated based on ASTM standards. Experimental investigation revealed that the 20% blend resulted in 4.18%, 5.12% more prominent performance characteristics of brake thermal efficiency, brake specific energy consumption, and superior emission diminution of 5.26% of HC, 16.6% of CO, 6.2% of smoke when compared with base diesel fuel, despite marginal penalty of 5.26% of carbon dioxide and 4.8% of oxides of nitrogen emission at full load condition. Characteristics of combustion parameters like pressure inside the cylinder and rate of the heat released were superior for 20% blend of MEME at the peak load condition.     

Experimental investigation of performance and emission characteristics of diesel engine using Jatropha biodiesel with alumina nanoparticles

Biodiesels have come up as a very strong alternative for diesel fuel. Biodiesels such as Jatropha Oil Methyl Ester (JOME) are comparable in performance with that of the diesel engine. The thermal efficiency of engines fuelled with biodiesels was found lower than conventional diesel fuel but due to the bio-origin, the emission characteristics are much better. However, biodiesel increases the NOx emissions as these are rich in oxygen, hence nanoparticles are used in this experiment to curb the high temperatures and reduce the NOx formation. The experiment on naturally aspired diesel engine was conducted with four prepared test fuels other than neat diesel and neat biodiesel. The 50 and 150 of alumina nanoparticles were added separately to the pure diesel and pure Jatropha biodiesel to form the nano emulsions using ultrasonicator. The properties of nanoemulsion were evaluated using dynamic light scattering technique using zetasizer. The performance and emission characteristics of multi-cylinder diesel engine with these nanoemulsions were compared with that of neat fuels. The results showed that using nanoparticles with diesel and biodiesel can contribute in a more efficient, economical, and eco-friendly engine operation.
