Safety Climate in Finnish- and Swedish-Speaking Companies

The aim of this study was to compare assessments made by Finnish- and Swedish-speaking workers in Finland about the safety climate in their companies, because an earlier study showed that the accident frequency of Swedish-speaking workers was one third lower than that of Finnish-speaking workers. 148 Finnish-speaking and 138 Swedish-speaking workers from 14 small and medium-sized companies participated in this study. They filled out a Finnish safety climate questionnaire, the reliability of which was above the acceptable level. There were no differences between the language groups in the total variables of safety climate and safety action. Based on the differences in single items, we interpreted that Swedish-speaking workers stressed collective safety more, whereas Finnish-speaking workers put more emphasis on their personal responsibility for safety.     

Occupational Accidents of Finnish-and Swedish-Speaking Workers in Finland: A Mental Model View

This article is based on 2 studies. The aim of the first study was to examine the differences in occupational accident frequency between the 2 main language groups in Finland. Based on 3 independent statistical data sets, it was shown that Swedish-speaking workers had about 40% fewer occupational accidents than Finnish-speaking workers. The aim of the second study was to confirm the difference at company level. A field study in the province of Vaasa with 14 small and medium-sized manufacturing companies revealed that the accident frequency of Swedish-speaking workers was 21% lower than that of Finnish-speaking workers.     

宜兴煤矿安全经济护巷煤柱宽度的研究确定

为节省资源,留最窄护巷煤柱,在借用FLAC3D模拟软件掌握不同护巷煤柱宽度下巷道围岩应力应变后,结合模拟的结果和实验室试验新材料GRT-201加固后的煤岩体强度指标,最终确定煤柱留设宽度为2m,较正常煤柱宽度留设减小了20多米.现场操作后巷道的变形率控制在5％以内,大大降低留设煤柱宽度的同时保证了工作面的正常接替和安全回采.

SME application of LCA‐based carbon footprints

Following a brief introduction about the need for businesses to respond to climate change, this paper considers the development of the phrase ‘carbon footprint’. Widely used definitions are considered before the authors offer their own interpretation of how the term should be used. The paper focuses on the contribution small and medium sized enterprises (SMEs) make to the economy and their level of influence in stimulating change within organisations. The experience of an outreach team from the Engineering Department of a UK university is used which draws on the experience of delivering regional economic growth projects funded principally through the European Regional Development Fund. Case studies are used including the development of bespoke carbon footprints for SMEs from an initiative delivered by the outreach team. Limitations of current carbon footprints are identified based on this higher education‐industry knowledge exchange mechanism around three main themes of scope, the assessment method and conversion factors. Evidence and discussions are presented that conclude with the presentation of some solutions based on the work undertaken with SMEs and a discussion on the merits of the two principally used methodologies: life‐cycle analysis and economic input–output assessment.     

Renewable energy potential in India and future agenda of research

ABSTRACT

Demand of electrical energy is exponentially increasing causing environmental problems due to extensive use of fossil fuels. Hence, research has been promoted in renewable energy technologies to mitigate environmental pollution. Indian subcontinent is rich in renewable energy sources (RES). This paper describes potential of RES and region-wise installed capacity in India. Estimated potential of RES is 57 GW which is targeted to be 175 GW by 2022. A logical framework for our future research work has been presented. This includes performance optimisation of solar pumping system and reliability assessments of the designed system using reliability indices.

小流域面源污染减控措施优化管理

以长春市重要饮用水源地石头口门水库的莫家沟小流域为研究区,选择横垄耕作、修建梯田、退耕还林、化肥减施和人工湿地5种措施进行磷素削减处理,共计21个措施组合方案;以实施措施的费用最小为目标函数,以水库水质TP浓度和采用不同措施的土地面积为约束条件,建立小流域出口水质优化管理模型。模拟计算3个阶段的可行性最优方案分别为:2011—2020年,选取措施为施肥量不变,现状梯田面积不变,坡度≤5°的耕地采取横垄耕作,其他退耕还林;2021—2030年,在第一阶段实施方案的基础上,新建人工湿地0.03 km2;2031—2050年,全部农田原位退耕还林,保持人工湿地面积不变,最终实现入库水质ρ(TP)≤0.01 mg.L-1的目标。化肥减施和梯田建设面积是影响方案选择的主要因素。
