矿渣与工业废渣改良黄土的性能与机理研究进展

黄土在世界上分布面积较广,在我国也有约60×104 km2的分布,具有湿陷性是其区别于其它区域性土的最显著特点,并由此引发造成各种地质灾害和工程问题.采用石灰、水泥或高分子材料等对其进行改性以达到消除湿陷性或提高黄土强度的目的,是岩土工程领域的重要课题.选用矿渣和工业废渣作为改性参料,用以研究改性黄土的力学特性变化和改...     

工业园能源代谢分析

运用工业代谢分析方法对某农药化学工业园能源代谢系统进行量化分析. 结果表明:提升能源转化水平、改善能源利用效率是优化该工业园能源系统的2个有效途径,可减少能源代谢过程中的资源消耗与环境压力. 进一步根据能源代谢模型量化分析得出,提升工业园热电厂运行水平,达到供热煤耗0.043 t/GJ,供电煤耗4.538 t/(104 kW·h)(2004年江苏省平均水平),将较2005年水平减少原煤消耗35.31%;将能源利用水平较低企业的电力利用效率和蒸汽利用效率分别提高到园区平均水平(58.01%和63.84%),可较2005年水平减少原煤消耗2.5%左右.      

工业燃煤链条炉细粒子排放特征研究

链条燃煤锅炉是当前我国工业锅炉的最主要应用炉型,其容量占到了工业锅炉总容量的85%,是重要的大气污染物排放源之一.本研究在3个地区选取了5种典型容量的链条炉,应用自行设计的二级稀释系统现场测试其细粒子（PM_2.5）和各种气态污染物的排放特征.结果表明,链条炉烟气中的PM_2.5质量粒径呈单峰或双峰分布,第1个峰值在0.14 μm处,第2个峰值在1 μm后;湿法除尘和旋风除尘对PM_1.0的细粒子仍具有有效的去除效率;在相同或相似除尘控制技术的条件下,PM_2.5的排放水平随锅炉容量的增大而减小.在PM_2.5中,SO^2-₄是最丰富的离子,质量分数在20%～54%范围内;C是最丰富的元素,质量分数在7.5%～31.8%之间,其次是S,质量分数为8.4%～18.7%.采用碳平衡法计算得出PM_2.5、NO_x和SO₂的排放因子分别为0.046～0.486 　g·kg^-1、 1.63～2.47　g·kg^-1、 1.35～9.95　g·kg^-1,这为建立我国的工业锅炉排放清单及大气污染来源分析提供了必要的基础数据.

Participative Versus Assigned Production Standard Setting in a Repetitive Industrial Task: A Strategy for Improving Worker Productivity

Abstract

The participative standard with feedback condition was superior to the assigned difficult (140% of normal) standard with feedback condition in terms of worker productivity. The percentage increase in worker productivity with the participative standard and feedback condition was 46%, whereas the increase in the assigned difficult standard with feedback was 23%, compared to the control group (no standard, no feedback). Worker productivity also Improved significantly as a result of assigning a normal (100%) production standard with feedback, compared to the control group, and the increase was 12%. The participative standard with feedback condition emerges as the optimum strategy for improving worker productivity in a repetitive industrial production task.     

Occupational Cognitive Failures and Safety Performance in the Workplace

Introduction. The majority of industrial accidents occur because of human errors. Human error has different causes, however, in all cases cognitive abilities and limitations of human play an important role. Occupational cognitive failures are cognitively-based human errors that occur at work. The aim of this study was to examine the relationship between occupational cognitive failures and safety consequences. Method. Personnel of a large industrial company in Iran filled out an occupational cognitive failure questionnaire (OCFQ) and answered questions on accidents. Univariate and multiple logistic regression analysis were used to determine the relationship between cognitive failures and safety consequences. Results. According to developed regression models, personnel with a high rate of cognitive failure, in comparison to low rate, have a high risk of minor injury involvement (OR 5.1, 95% CI [2.62, 10.3]); similar results were for major injury and near miss. Discussion. The results of this study revealed usefulness of the OCFQ as a tool of predicting safety-related consequences and planning preventive actions.     

Multiple dimensions of work-related risk factors and their relationship to work ability among industrial workers in Iran

Objectives. The present study was designed to investigate the simultaneous effects of physical, psychosocial and other work-related risk factors on the work ability index (WAI) score among industrial workers. Methods. This study used a cross-sectional design with a questionnaire survey. A total of 280 workers were included in the study. Data were collected using three questionnaires including the Persian version of the WAI, the Persian version of the job content questionnaire and an author-developed measure (to assess work-related factors, health-related factors and socio-demographic characteristics). Results. The majority of the participants were young, but they had poor WAI scores (mean 37.3?±?6.4) and 44.3% of them had poor or moderate work ability. Occupational accidents and injuries were found to be the strongest predictors of WAI scores. Additionally, there was a strong association between WAI scores and supervisor support, skill discretion, occupational training, sleep quality, work nature and educational level. Conclusions. Intervention programs should focus on improving supervisor support, sleep quality, job skills and knowledge and on decreasing physical and mental work demands. Additionally, implementing a comprehensive occupational health and ergonomics program for controlling and reducing hazardous working environments and occupational injury rates should be considered.
