元首们的健康生活

布莱尔:狂爱足球的健将英国首相布莱尔一直是一名活跃的"体育健将".中学时代,他是非常出色的校橄榄球队队员,还当过校板球队队长,以后又对篮球和网球颇感兴趣.做首相后,虽然工作繁忙,但布莱尔仍然定期游泳、打网球、上健身房.很多时候,布莱尔一家还要同保镖们拉开架势,来一场别开生面的"家庭足球大赛".如此注重锻炼,难怪布莱尔自豪地表示,他现在的身材跟大学刚毕业时一样标准.

一起丙烯腈贮罐爆炸事故分析

[本刊讯]2月7日14时50分,厦门长天塑化有限公司东区一空置两年多的丙烯腈(V5006)贮罐发生爆炸,并导致相邻3.5米的(V5005)丁酯储罐外表冷却层燃烧,事故虽未造成人员伤亡和环境污染,但造成了极大的社会影响.事故发生后,市、区安监、消防,海沧公安、环保等单位领导及工作人员迅速赶到事故现场,对事故进行调查处理.经初步分析:事故原因是由于公司没有严格动火制度,员工切割丙烯腈回流管时产生火花引起丙烯腈回流管着火,火源经管道引至储罐,导致丙烯腈储罐爆炸.

Flammability of heat transfer fluid aerosols produced by electrospray measured by laser diffraction analysis

Accidental release of pressurized high flash point heat transfer fluids can result in fire and explosion hazard scenarios in the process industry. An experimental investigation on ignition of aerosols of a heat transfer fluid is carried out, and characterization of aerosol and its ignition process by non-intrusive laser diffraction technique is reported. Propagation speed of the aerosol combustion flame front as analyzed from the laser diffraction measurement agrees with high-speed visual camera observation. Flammability of the aerosol, which is based on the chances of the global flame appearance in the aerosol, is mainly controlled by aerosol droplet size and the droplet volume concentration.     

Protection Against Dust by Respirators

This article is a brief review of the mechanism of action of fibrous filters and of the performance of respirators; it neglects many of the complications discussed in longer and more detailed articles. An expression is given for the pressure drop across a filter in terms of fibre diameter and filtration velocity. The particle capture mechanisms of interception and diffusional deposition are introduced and the way in which filtration efficiency varies with particle size is discussed. Filters with fibres of small diameter are shown to be the most efficient, but their use can cause problems. Electrically charged materials are widely used in respirators because of their high efficiency and low pressure drop. Types of material, their means of charging, and their method of action are described. An account is given of respirator leakage, the protection factor, and of the way that these may vary in a period of use. The leakage of air and particles through face seal leaks and leaky valves is discussed. The frequent discrepancy in the protection given by respirators in the workplace, on the one hand, and that suggested by laboratory measurements, on the other, is reviewed, and the article ends with an account of the combined effect of aerosol penetration through a filter and through a leak.     

Combating interference by unauthorised persons

Under the new threat situation it is necessary to impede and if necessary detect ingress by unauthorised persons into the relevant establishment. It may be necessary to take additional measures to protect installations or parts thereof that are especially hazardous or at risk from terrorist attacks from interference by unauthorised persons.

It is the duty of the state to take precautionary and preventive measures to impede or prevent external terrorist attacks or entry by force into establishments. The necessary resources for this purpose must be made available even in times of limited budgets.

Since total protection can never be guaranteed, external emergency measures have a particularly important role to play. The competent authorities in this sector must receive the necessary information from the operators and must take the measures within their sphere of responsibility without delay.

Much of the information necessary for assessment of the risk situation by the operators and the authorities is already available under the provisions on the safety report and the external alarm and emergency plans according to European Seveso II Directive (96/82/EC).

It is recommended that a restriction of disclosure of information on the grounds of public safety should only be permitted for establishments/installations which are to be regarded as security-relevant on the basis of the hazard and the risk analysis.

The outline of the systematic approach of a security analysis like it is proposed in Germany is described separately.     

Initiation of dust explosions by electric spark discharges triggered by the explosive dust cloud itself

An investigation of ignition of dust clouds by the use of electric spark discharges triggered by the explosive dust cloud itself has been conducted. This method of triggering capacitive sparks probably represents a realistic mechanism for initiating accidental dust explosions in industrial practice. Unlike the conventional method for determining the minimum ignition energy (MIE) in the laboratory, the delay between dust dispersion and spark discharge is not a degree of freedom. In stead, the transient dust cloud itself is used to initiate spark breakdown between electrodes set at a high voltage lower than breakdown in pure air. In the present study, different kinds of dusts were tested as ‘spark triggers’, and they exhibited quite different abilities to trigger breakdown. Large particles were found to initiate breakdown at lower voltages than smaller ones. In general, conductive particles were not found to initiate breakdown at lower voltages than dielectric ones when using the same dust concentration.Minimum ignition energies (MIE) of three dusts (Lycopodium clavatum, sulphur and maize starch) were determined using the authors' method of study. The MIEs were somewhat higher than those obtained using conventional methods, but relatively close to the values obtained through conventional methods.     

碳纳米管对不同分区溶解有机物的吸附研究

选用单壁碳纳米管、多壁碳纳米管两种吸附剂,对广州市3种地表水体(城市径流、农田径流、森林径流)中不同分区溶解性有机物(DOM)进行吸附研究,并以腐殖酸溶液作为标准对照组。以UV254、荧光激发-发射矩阵光谱、溶解性有机碳质量浓度作为吸附效果的评价指标。结果表明,在UV254上,单壁碳纳米管比多壁碳纳米管平均多吸附11%的DOM。3种地表水样中均无Ⅰ区荧光峰,而有明显的Ⅱ、Ⅲ、Ⅳ区荧光峰。水样中II区、III区、IV区、Ⅴ区荧光峰的位置分别为Ex230/Em345、Ex245/Em445、Ex275/Em320、Ex335/Em380,误差在40 nm内。多壁碳纳米管吸附溶解性有机物的动力学模式符合准二级动力学方程,决定系数高达0.994 7。Langmuir方程相对于Freundlich方程更适合描述MWNT-1030对DOM的吸附过程。

Suicidal behavior by motor vehicle collision

BACKGROUND: The ability for suicides of drivers to be disguised as traffic accidents raises the possibility that suicidal behaviors of this nature are far more prevalent than previously thought, potentially impacting health, road safety, and insurance companies. METHOD: Persons residing at the Gold Coast, Australia, identified as having a history of suicidal ideation and behaviors (n = 1,196), were sent a mail-out survey after their consent was obtained in initial telephone contact (CATI random digit-dialing). Among those responding, 412 had made suicide plans or arrangements and 228 suicide attempts. RESULTS: Of those who reported planning a suicide, 14.8% (19.1% of male planners and 11.8% of female planners) had conceived to have a motor vehicle "accident" (n = 61). Of all attempters, 8.3% (13.3% of male attempters) had previously attempted via motor vehicle collision (n = 19). All attempters reported having emotional or mental problems at the time of the event. Suicide planners were significantly more likely to be in full-time employment and have a partner and children compared with other planners. CONCLUSION: The study gives a rare insight into driver suicide plans and attempts, via a large-scale community survey, to provide the best opportunity of collecting unbiased data on the driver suicide behavior. Results suggest the use of this method, particularly in attempts made by males, may be underreported leading to inaccuracy of statistics. The motives behind choosing this method are somewhat different to those behind other methods, including financial benefits and eliminating stigma in the aftermath of a suicide.     

Thermal shielding by water spray curtain

The mitigation of the consequences of storage-tank fire is a great safety concern in petro-chemical and gas industries. A technique to protect the integrity of neighbouring structures is the water spray curtain. It can be operating downward in front of or oriented to the surface to be shielded. Simple modelling, laboratory experiments and field tests for these two types of thermal shielding are presented.

Attenuation factor of 50–75% can be expected with the vertical curtain while 90% can be reached with the impinging curtain if spray overlapping is achieved.
