脱硫细菌的培育及最佳生长条件的研究

从云南某硫化矿酸性废水中，分离出一株氧化亚铁硫杆菌，其最佳生长条件的研究表明，最佳培养温度为30％左右，最佳生长pH为2．0～2．5，最佳生长初始Fe^2＋浓度为0．15mol／L左右，同时在进行细菌培养时接种量取在10％是比较恰当的。

Of Bodies, Place, and Culture: Re-Situating Local Food

In the US, an increasingly popular local food movement is propelled along by structural arguments that highlight the inequity and unsustainablity of the current agri-food system and by individually based arguments that highlight personal health and well-being. Despite clear differences in their foci, the deeper values contained in each argument tend to be neglected or lost, while local innovations assume instrumental and largely market-based forms. By narrowing their focus to the rational and the economic, movement activists tend to overlook (or marginalize) the role of the sensual, the emotional, the expressive for maintaining layered sets of embodied relationships to food and to place. This paper seeks to show that cultural and nonrational elements are fundamental to local food discussions. It proceeds from the assumption that, without them as full partners, the movement cannot be sustained in any felt, practiced, or committed way. To this end, it discusses the concept of place and bodies in place, as well as the connections between the ecological and the cultural, the sensual and the scientific. It offers a new set of questions and conceptual tools with which advocates and activists may “ground,” and thereby revalue and restore, the promise and practice of local food.     

石化企业安全文化建设

随着国企改制的不断深化,安全管理显现出许多薄弱环节,尤其是在能源勘探开发过程中发生的重特大事故,不断给安全生产发出了黄牌警告.近年来,多种因素导致员工"三违",造成恶性事故不断,其原因是由于企业缺乏安全文化氛围和员工缺乏必要的自我安全保护意识,盲目蛮干导致事故高发.因此,加强企业安全文化建设是提高全员安全意识的一种行之有效的方法,并可以进一步促进和提高员工的自我安全保护意识和安全技术素质.本文阐述了企业安全文化建设在新形势下的重要意义,并针对石化企业开展安全文化建设提出几点建议.     

Not drowning, waving!: Safety management and occupational culture in an Australian commercial fishing port

An ethnographic study of safety management was conducted in a commercial lobster fishing industry, in a small fishing town in Southern Australia. The objectives were to test the utility of the ethnographic method for exploring the nature of the relationship between occupational culture, workplace social organization, and safety management.Available accident data suggests this particular fishery may not have the same high incidence of occupational trauma normally attributed to commercial fishing. Changes in licensing laws and improved management of fish stocks have significantly reduced risk exposure. Participants in this study had a good understanding of their physical workplace risks, but accepted some of these with too few defences. Wear rates of personal flotation devices (PFDs) were below 1% for the study period.The paper suggests that participants do not have a strong learning culture, and links this to occupation-wide cultural assumptions, other external issues and safety management issues. Assessment of the social and cultural context of safety management can offer policy makers a ‘road-map’ to guide their interventions. The utility of ethnographic methods for this type of analysis is significant, and will be enhanced by improving the transparency of the research method.     

浅析推进校园安全文化建设

校园,特别是普通高等院校的校园作为文化、科学、技术的人才培育基地,应始终代表中国先进文化的前进方向,实践安全文化的理论研究和探索,为人类抵御各种灾害事故提供精神和智力支持。因此,倡导和推进高校安全文化建设,已成为时代赋予高校的又一项社会责任。笔者浅析安全文化的内涵、安全文化的功能,并对推进高校安全文化建设的意义进行探讨,提出了高校安全文化建设的途径。     

Metaprotella Sandalensis (Crustacea: Amphipoda: Caprellidae): A Bioindicator of Nutrient Enrichment on Coral Reefs?

The population of the caprellid Metaprotella sandalensis Mayer (Crustacea: Amphipoda) associated with the seaweed Turbinaria ornata (Turner) J. Agardh was studied on a spatial scale in relation to the influence of physico-chemical factors on the coral reef system at Mauritius Island. Some areas of the coast of Mauritius are currently subject to disturbance due to industrialisation and rapidly growing tourist development programmes, meanwhile other sites of the island are still unaltered. T. ornata was sampled at 12 stations, distributed around the whole island to represent the heterogeneous conditions. The density of Metaprotella sandalensis living on T. ornata was measured. The linear regression and the multivariate analysis showed a strong correlation between the densities of the caprellid and the physico-chemical parameters. The highest densities of M. sandalensis were found in the most stressed sites characterised by the highest values of nitrate, phosphate, chemical oxygen demand and silting. According to these results and taking into account that M. sandalensis and T. ornata are widely distributed in most of the tropical ecosystems, we preliminarily propose usage of the density of this caprellid as a new monitoring tool on coral reefs or, at least, as a first diagnosis for the detection of nutrient enrichment on these ecosystems.     

一切建筑事故都是可以预防的

通过分析建筑事故的种类及其成因,以及建筑事故与自然现象和人为因素之间的关系,论证了建筑生产企业中的人因事故是可以预防的,而且通过预测预报、预警预防、应急救援、加固改造等手段,尤其是采取合理规划选址、避开地震发生区进行建设开发等有效、合理的技术措施,自然原因造成的环境类建筑事故如地震灾害等也是可以预防的。无论从建筑事故发生的原因角度出发,还是从建筑事故的性质特点角度出发,建筑事故适合用分析和拓扑理论进行研究,用因子分析法,结合指标分析和拓扑理论,可以得出一切建筑事故都是可以预防的结论。     

燕岩溶洞旅游资源及其旅游深度开发研究

广东怀集的燕岩溶洞因金丝燕的定期群居而成为独特的溶洞旅游景观。基于对它的深入考察，阐述了地貌环境与结构、小气候生境、溶蚀过程等与金丝燕群居于此溶洞的关系。结果表明，新生代造山运动形成的高险地貌，继之溶蚀形成的节理裂隙发育的巨洞为金丝燕提供了着附的安全环境；宽阔的地下河及其造就的高湿度提供了金丝燕习惯栖息的海洋性小气候；硬质水温条件以及盆地孤峰模拟的海岛生境则成为金丝燕久居的重要原因。燕岩旅游资源划分为观赏性旅游资源、参与性旅游资源、娱乐性旅游资源等不同类型，形成洞内与洞外不同组合。燕岩旅游的深入开发有赖于对生态文化的发掘。为此，要通过客流分流、建筑控制、活动限定等措施保护金丝燕的生存环境；提炼金燕文化的精髓，积极利用“燕子节”等节庆活动以及其它文化场馆展示其深厚的文化底蕴，优化旅游资源结构，塑造燕岩生态文化旅游的独特品牌形象。     

基于PDCA模式的化工企业安全文化探讨

近年来,化工事故屡次发生,给国家和人民带来了巨大的经济损失.为了减少化工企业的安全生产事故,有的通过HSE管理体系降低安全事故率,有的通过危险性评价来控制危险源.从文化管理的角度探讨化工企业的安全文化建设问题,以期减少化工企业的安全生产事故. 根据安全文化管理的优势以及化工生产的特点,引入PDCA管理模型,把化工企业安全文化建设分4个阶段,系统地讨论了化工企业的安全文化建设问题,并且形成了一套化工企业的文化建设体系,可供企业参考.
