The value systems of college students are presumably as representative of the respective national cultures as the value systems of any other group wou 当已经担任管理职务的个体反应是利益时,对学生应答者的用途似乎适当对研究问题。 大学生价值系统作为据推测是各自全国文化的代表,象其他小组价值系统。 早先...
WJ Bailey,RB Jr,RA Baylouny - 《Journal of Organic Chemistry》 被引量: 339发表: 1962年 Evidence for a [2+4] cycloaddition in the ion-molecule reaction of ionized 1,3-butadiene with vinyl ethyl (methyl) ether in the gas phase By use of deuterium labelling it is shown that the radical...
Tissue engineered products (TEPs), which mean biomaterials containing either cells or growth factors or both cells and growth factors, may be used as an alternative to the autografts taken directly from the bone of the patients. Nevertheless, the use of TEPs needs much more understanding of bio...

Accidental and intended Ricinus communis intoxications in humans and animals have been known for centuries but the causative agent remained elusive until 1888 when Stillmark attributed the toxicity to the lectin ricin. Ricinus communis is grown worldwide
The goal of this session was to synthesize and conclude together with attendees: Can we predict how secondary products and in particular ozone-initiated terpenoid reaction products and secondary organic aerosols cause health effects and under what circumstances? Can we identify which compounds cause ...
Further, a number of research groups reaffirmed a need for better understanding of biological mechanisms and apparent associations of various health effects with components of particulate matter (PM), such as elemental carbon, certain organic species, ultrafine particles, and certain trace elements such...
