Risk management of road and rail transport of hazardous materials in Sicily

A Transportation Risk Analysis (TRA) tool has been used to accurately assess the risk associated to a variety of road and rail transportation cases representative of hazardous materials transport by land in Sicily. Due to the high risk level, some risk mitigation options have been investigated: the possibility of changing route and/or transport modalities have been examined for each transportation activity, all the combinations of road, rail and intermodal (road+rail) transport have been calculated and that minimising the risk has been identified with the aid of the TRA tool.

The impact of job security,satisfaction and stress on performance assessment and optimization of generation companies

In this study, performances of Iranian thermal power plants have been assessed with respect to human factors such as job stress, satisfaction and security through data envelopment analysis (DEA). In the first step performance of power plants (DMUs) have been evaluated considering traditional production factors including installed capacity, internal consumption and fuel consumption as inputs and gross production as output (model 1). In the next step, model 1 is expanded to include three above mentioned human factors (model 2). Power plants have been ranked based on their relative efficiency scores in both models. Pearson and Spearman correlation coefficients between relative efficiency scores and rankings of power plants in two models have been calculated. The results show that efficiency scores and rankings of power plants in two models are quite different indicating that mentioned human factors have direct impact on overall performance of generation companies and that if we were to use just traditional factors it would not reflect the optimum efficiency of the DMUs. Finally, job security has been found as the most effective human factor in Iranian power plants. This is the first study that presents an integrated approach for assessment of electric power plants considering job stress, security and satisfaction. And it is shown that these human factors play important role in overall performance of generation companies.     

滑坡集成监测系统的研制

测量机器人(即自动电子全站仪)固然可以对滑坡进行自动化(或半自动化)监测,但测量机器人设站处(监测基点)的稳定性对监测精度的影响非常大,并且当测量视线被遮挡后测量机器人将无法监测相应的监测点.为了解决上述问题,笔者及科研组将GPS技术与测量机器人技术有机结合,开发出了滑坡集成监测系统.该系统彻底解决了监测基站不稳定对监测结果的影响问题,使监测的程序得以简化、监测的固定性投资成本得以降低.文章介绍了滑坡集成监测系统的结构、工作原理,给出了监测实例.以实际监测数据为依据,提出了滑坡预警的基本准则.

Modelling and control of the dispersion of hazardous heavy gases

Dispersion of several common `heavy' gases (ethylene, propylene, ammonia, and chlorine) has been modelled on the basis of modifications in plume path theory. The model takes into account, among other things, the variations in temperature, density, and specific heat during the movement of the heavy gas plume. The effects of wind speed, density of the gas, and venting speed on the plume dispersion have been simulated. Based on the simulations a set of empirical equations has been developed. The equations have been validated by theoretical as well as experimental studies.Studies have also been carried out to simulate the effect of venting speed (manipulated by injecting hot air with the released gas) on the plume dispersion. The study reveals that the effect of venting speed on dispersion is very pronounced and can be used to reduce the risk posed by the accidental luxurious release of toxic/flammable gases. For example an increase of 20% in venting speed of chlorine (54.1 m/s) can reduce the distance up to which toxic concentration would occur by about 1100 meters.
