Essential oils obtained from hydrodistillation of three medicinal plants grown in Vietnam were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). The monoterpene hydrocarbons, α-pinene (50.2%), β-pinene (23.6%) and limonene (5.3%) were the most abundant constituents of the rhizome oil of Zingiber collinsii Mood & Theilade (Zingiberaceae). The main compounds of the stem oil of Croton kongensis Gagnep., (Euphorbiaceae) were benzyl benzoate (12.7%), β-selinene (9.8%), bulnesol (8.0%) and 5,6,7,8-tetrahydroquinoxaline (7.4%). The leaf oil of Goniothalamus albiflous Ban., consisted mainly of α-pinene (26.2%), caryophyllene oxide (10.6%) and 1,8-cineole (9.7%). The composition of the oils of Zingiber collinsii and Croton kongensis was being reported for the first time.

近年来,刺激响应聚合物因其独特的性质而受到广泛关注,这类聚合物能够感受外界环境刺激(包括光、电、热、力、氧化还原、pH、化学、环境和生物信号等刺激)而产生响应,从而引起体系物理或化学性质的改变。而梯度聚合物则是伴随着可控自... 详细信息

近年来,刺激响应聚合物因其独特的性质而受到广泛关注,这类聚合物能够感受外界环境刺激(包括光、电、热、力、氧化还原、pH、化学、环境和生物信号等刺激)而产生响应,从而引起体系物理或化学性质的改变。而梯度聚合物则是伴随着可控自由基聚合技术的诞生、发展而出现和形成的一类新型聚合物,区别于无规和嵌段聚合物,梯度聚合物表现出单体组成沿分子链渐变的性质,其中,由亲水性单元和憎水性单元组成的两亲性梯度聚合物在选择性溶剂中可自组装形成多种聚集体,因此具有多方面的潜在应用价值,比如超分子组装体、智能涂料、网络或这些可能应用的组合。本文调研了有关梯度聚合物方面的研究工作,综述了几种梯度聚合物的合成方法,如活性阴离子聚合法、可控自由基聚合法(包括氮氧稳定自由基聚合、原子转移自由基聚合及可逆加成断裂链转移自由基聚合)和开环聚合法等,同时阐述了梯度聚合物的自组装及刺激响应行为,尤其是其独特的热和pH敏感性。此外,还对由两亲性嵌段聚合物和两亲性梯度聚合物自组装形成的聚集体的刺激响应行为进行了详细地论述和比较,并指出了梯度聚合物的应用前景和发展方向。

The experiment was conducted by using 20 bulls of Lai Sind cattle (a cross breed between Red Sindhi and local Vietnam yellow cattle) from 15 - 16 months of age, weighed approximately 154 - 156 kg, housed individually with provision of adequate feed trough and free access to water to evaluate the effect of tannin sourced from green tea by-product and addition of bio-char on methane production and animal performance. The experimental diets were formulated by replacing elephant grass in basal diet by bio-char and green tea by-product with the replacement of 0.5 - 1 bio-char and 3% - 5% green tea by-products, respectively to make the content of tannin in the diet of 7.3 g and 12.5 g tannin per kg dry matter. Results from this study revealed that bio-char and green tea by-product included into the diet with different levels had significantly affected on the feed intake, as the increasing level of tannin in the diet tended to increase the feed intake. The inclusion of green tea by-product in the diet which resulted in the content of tannin in the diet of 12.5 g/kg DM had significantly reduced methane emission without altering animal performance, thus the inclusion of 0.5% bio-char and 5% of green tea by-product can be applied in order to mitigate methane emission, thus contributed to environment protection.

越南制糖业热电联产的发展前景

越南每年生产大约15 0 0万吨的甘蔗和大约5 0 0万吨的蔗渣。有利用蔗渣来发展热电联产的潜力,这可以帮助该国克服目前的电力短缺。本文分析了三种方案下越南制糖业发展热电联产的潜力所在,发现如果利用糖厂加工甘蔗后剩下的蔗渣进行发电,每年可发电10 0～30 0兆瓦,这要根据糖厂和热电厂所采用的技术不同以及现有糖厂改造的可能性而定。本文也评价了这样一种热电联产的投资成本情况,结果发现,对所有类型的糖厂来说,这将都是一个有利可图的方案。作者还发现,从热电联产所节省下来的费用将完全能够弥补由于糖厂甘蔗加工技术效率不高而引入热电联产时的成本。而有现代技术的糖厂将有大量的剩余电力,这些厂的大多数将能够盈亏平衡,如果它们以大约4 .5美分/ k Wh出售它们的剩余电力时。投资成本的假设条件对盈亏平衡成本和平均生产成本的关系很大。本文建议,制糖业的热电联产无论是对现有糖厂还是新建糖厂的投资者都一样是一个有吸引力的方案。
