欧洲橱柜行业发展趋势

舒乐公司是由德国舒乐先生在1956年创立的，是一个咨询性的企业，已经有了将近50年的经历，到目前为止已经参与了将近3千个工厂设计和流程优化项目，已经具备覆盖全球的服务网络。能够做到这个程度，也是因为我们舒乐是属于整个豪迈集团的一个部分，并与器械分销商建立一种联系，从咨询设备开始，豪迈集团不仅为大型的木工企业提供咨询，同时也为非常小的企业提供咨询，最大的企业有将近9千多名员工，最小的企业也尝试过只有8个雇员。为企业设计工厂的面积最小只有将近500平米，最大的达到11万平米。从1956年开始，舒乐公司进行了工厂组织管理的研究。舒乐先生的目标是希望我们的木工企业具备更好的提高效率，能够赢得利润，能够更具有竞争力。包括成本控制，以及对员工的奖励和激励政策。1974年开始对在木工行业计算机应用技术的研发。海尔是舒乐在中国长期的合作伙伴，包括在德国非常多的大型的企业也在使用舒乐的软件系统。     

Lipid stability during the frozen storage of fillets from silver catfish exposed in vivo to the essential oil of Lippia alba (Mill.) NE Brown

BACKGROUND: Lippia alba is effective in sedating and reducing stress to fish during transportation. Because some in vitro studies have demonstrated the antioxidant activity of L. alba, we hypothesized that its use in vivo could result in antioxidant effects post mortem. Therefore, in this study we evaluated whether the essential oil of L. alba (EO) used as sedative for fish transport would increase the lipid stability of fillets from silver catfish during frozen storage. RESULTS: The exposure to the EO in vivo did not affect conjugated diene values. However, EO (30 and 40 µL L^?1) delayed the peak formation of peroxides (from the third to the sixth month of storage) and thiobarbituric reactive substances (from the ninth to the twelfth month of storage) when compared to control fillets. After exposure to 40 µL L^?1 EO the free fatty acid content was higher than for control at the start of fillet storage, with no differences among groups thereafter. CONCLUSION: The essential oil of L. alba used as sedative in the water to transport silver catfish can delay lipid oxidation of fillets during frozen storage. Thus L. alba may be a promising source of natural active compounds for use in aquaculture and the food industry. © 2012 Society of Chemical Industry     

An overview on bioaerosols viewed by scanning electron microscopy

Bioaerosols suspended in ambient air were collected with single-stage impactors at a semiurban site in southern Germany during late summer and early autumn. Sampling was mostly carried out at a nozzle velocity of 35 m/s, corresponding to a minimum aerodynamic diameter (cut-off diameter) of aerosol particles of 0.8 mum. The collected particles, sampled for short periods ( approximately 15 min) to avoid pile-up, were characterized by scanning electron microscopy (SEM). The observed bioaerosols include brochosomes, fungal spores, hyphae, insect scales, hairs of plants and, less commonly, bacteria and epicuticular wax. Brochosomes, which serve as a highly water repellent body coating of leafhoppers, are hollow spheroids with diameters around 400 nm, resembling C(60) or footballs (soccer balls). They are usually airborne not as individuals but in the form of large clusters containing up to 10,000 individual species or even more. Various types of spores and scales were observed, but assignment turned out be difficult due to the large number of fungi and insects from which they may have originated. Pollens were observed only once. The absence these presumably elastic particles suggests that they are frequently lost, at the comparatively high velocities, due to bounce-off from the nonadhesive impaction surfaces.

Plasma-assisted chemical vapor deposited silicon oxynitride as an alternative material for gate dielectric in MOS devices

Silicon oxynitride films have been deposited on Si substrates at 200 °C by a remote-plasma-assisted process in a RF-plasma CVD reactor using Si(OC₂H₅)₄ (TEOS) as a precursor and nitrogen as gas ambient. During deposition the Si substrates were biased with negative voltages of −120 and −600 V or were under no DC bias and the influence of this voltage on the film properties has been considered. Film parameters, such as density, chemical bonds, refractive index, composition, oxide and interface charge densities of the deposited dielectric films have been estimated by analysis of the results from the infrared (IR) spectroscopy, spectral ellipsometry (SE) and capacitance-voltage (C-V) measurements. The IR and SE results have proven the films are oxynitrides of silicon with predominantly oxide network. The analysis of the capacitance-voltage characteristics has shown that the dielectric charge densities increase with increasing DC bias but they remain considerably low in comparison to that for a standard SiO₂/Si structure before any annealing steps.     

SUVA as control parameter for the effective ozonation of organic pollutants in secondary effluent.

Recent research projects have shown a good suitability of the ozonation process to transform trace concentrations of most pharmaceuticals in wastewater treatment plant (WWTP) effluents. The concentrations of carbamazepine and 17 alpha-ethinylestradiol, for instance, were reduced below their detection limits by use of ozone dosages resulting in a specific ozone consumption of 0.5 mg O3/mg DOC0. At the same time a good disinfection performance was achieved. The given hygienic requirements of the EU bathing water directive (e.g. 2,000 N/100 mL faecal coliforms) are fulfilled without the formation of bromate (<10 microg/L). As technical control parameter of the ozonation process usually the residual ozone in the liquid phase or in the off-gas are used. However, at very low specific ozone consumptions, ozone reacts instantaneously with dissolved compounds and cannot be detected. Hence, alternative parameters should be used for effective operation control. The present paper evaluates the relation between UVA decrease and the removal of different compounds (endocrine disrupting compounds, pharmaceuticals, iodinated X-ray contrast media), microbial parameters and bromate formation. The results can be used as a guideline for the control of the oxidation performance at large scale ozonation units.
