基于人机工程学的可升降办公桌设计研究

文章分析了传统坐姿办公引起的健康问题,指出采用可升降办公桌实现站坐交替是保证健康办公的重要措施,并利用三维数字人体模型实测从人机工程学角度分别对升降办公桌各主要人机尺寸进行系统的分析研究,提出符合中国人健康办公要求的可升降办公桌的设计尺寸范围。坐姿下的桌面高度:700~760mm,站姿下的桌面高度:950~1350mm,桌面的长度:1 300~1500mm,桌面的宽度:810mm,坐姿下支肘高度:200~312mm,站姿下支肘高度:950~1 050 mm,两肘支撑的间距:500 mm,控制钮的高度:850 mm。     

办公椅中的人体工程学原理

办公椅是一种工作用椅，舒适度是它的主要要求，到现在为止，办公椅的设计是不正确的因为这些设计不能使人保持理想的坐姿。坐椅设计上的这种不足称之由“结构性缺陷”．为保持理想的坐姿，介绍了靠背、座面、中心支架的注意点。     

快乐早餐桌

早餐桌似乎可以成为一种标志,就像是否戴着婚戒一样,它不是必须的.但却象征着一种生活,每个人都应该坐在桌前认真地享用早餐.虽然一张早餐桌未必能真地改变什么.但它会提醒你去改变.     

SHA坐具之韵律——源自维也纳

什么坐姿是最舒服的?答案是:最舒服的坐姿永远是下一个坐姿。在这简单的论述背后隐藏着一个哲理。Variéer,一个新的坐具家具品牌把这个论述作为设计的前提。人生来是运动的、而不是坐着的。因此Variér生产的椅子是革命性的椅子。这个Norwegian公司的椅子,凳子和躺椅都可以不停的动,这样人坐在上面可以有身本的运动以及恢复新的创造力。     

从人体工程学看电脑桌的误区

在购买电脑时,必须挑选一个合适的电脑桌,因为它与您的健康有着密切的关系。我们每天可能要有几个小时坐在电脑桌前操作,不合适的电脑桌给健康带来的累计损害就不是一件可以忽略的小事情了,它不仅会带来颈肩腕综合症,而且会使视力下降。尤其对处于成长发育阶段的青少年学生,这种不利影响所造成的伤害可能会影响孩

扮酷你的桌面

打开电脑．整天面对的都是windows系统的桌面，时间一长，是不是有点枯燥呆板的直觉？想过把你的桌面打扮一下吗？呵呵，那就让我们白己动手来扮酷我们的桌面吧。     

布匹复验的半自动装置

我厂一织整理车间布匹复验原来是两人站在一只长方桌对面,左右走着翻布查看,后改为两人对面坐在凳上用手左右移动桌面翻布查看(桌面下装有四只滚珠轴承),但是劳动强度仍较高,经我厂有关技术人员和工人同志一起研究,试制成了半自动装置,可以不必用手左右移动桌面,而通过电动机构来回移动桌面,两人只需坐着翻布查看,如发现布面     

Beer brewing using a fusant between a sake yeast and a brewer's yeast

Beer brewing using a fusant between a sake yeast (a lysine auxotrophic mutant of sake yeast K-14) and a brewer's yeast (a respiratory-deficient mutant of the top fermentation yeast NCYC1333) was performed to take advantage of the beneficial characteristics of sake yeasts, i.e., the high productivity of esters, high tolerance to ethanol, and high osmotolerance. The fusant (F-32) obtained was different from the parental yeasts regarding, for example, the assimilation of carbon sources and tolerance to ethanol. A brewing trial with the fusant was carried out using a 100-l pilot-scale plant. The fusant fermented wort more rapidly than the parental brewer's yeast. However, the sedimentation capacity of the fusant was relatively low. The beer brewed using the fusant contained more ethanol and esters compared to that brewed using the parental brewer's yeast. The fusant also obtained osmotolerance in the fermentation of maltose and fermented high-gravity wort well.     

Tobacco smoking using a waterpipe: a re-emerging strain in a global epidemic

Objective: To conduct a comprehensive review regarding global waterpipe use, in order to identify current knowledge, guide scientific research, and promote public policy.

Data sources: A Medline search using as keywords "waterpipe", "narghile", "arghile", "shisha", "hookah", "goza", "hubble bubble" and variant spellings (for example, "hooka"; "hukka") was conducted. Resources compiled recently by members of GLOBALink were used.

Study selection: Every identified published study related to waterpipe use was included.

Data synthesis: Research regarding waterpipe epidemiology and health effects is limited; no published studies address treatment efforts. Waterpipe use is increasing globally, particularly in the Eastern Mediterranean Region, where perceptions regarding health effects and traditional values may facilitate use among women and children. Waterpipe smoke contains harmful constituents and there is preliminary evidence linking waterpipe smoking to a variety of life threatening conditions, including pulmonary disease, coronary heart disease, and pregnancy related complications.

Conclusions: More scientific documentation and careful analysis is required before the spread of waterpipe use and its health effects can be understood, and empirically guided treatment and public policy strategies can be implemented.

Latex as a sunscreen carrier in a silicone vehicle

This work comprises a study of the adsorption-desorption of three chemical sunscreens on the polymer surface of the latex Aquacoat, which has a high specific surface. The aim was to delay the release of these filters from the silicone excipient containing them and therefore increasing the substantivity, i.e. prolonging the sunscreening effect.
