Physicochemical characteristics of various milk samples available in Pakistan     

Imran M  Khan H  Hassan SS  Khan R 《Journal of Zhejiang University. Science. B》2008,9(7):546-551

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.  相似文献

Effects of medium composition on the production of plasmid DNA vector potentially for human gene therapy     

Xu ZN  Shen WH  Chen H  Cen PL 《Journal of Zhejiang University. Science. B》2005,6(5):396-400

INTRODUCTION The difficulties associated with large-scaleproduction of biotherapeutics provide a constantchallenge to the biotechnology industry. FDA hadadded “therapeutic DNA plasmid vectors” to the listof well-characterized biotechnology product (DoHHs,1996), and gene therapy has moved rapidly fromlaboratory scale to clinical trials. It is urgent to de-velop new protocols to obtain high-quality plasmidswith high yields and minimal or no contamination ofRNA and chromosomal D…  相似文献

Parents' and teachers' evaluations of the communicative abilities of deaf children     

Knoors H  Meuleman J  Klatter-Folmer J 《American annals of the deaf》2003,148(4):287-294

The authors compared evaluations by parents and teachers of the communicative abilities of deaf children. Such comparisons between parents' and professionals' assessments of the language development of children who are deaf can provide useful information on which to base ecologically valid intervention approaches. A secondary interest of the authors was to investigate the possible influences on language development of gender, the presence or absence of cochlear implantation, and communication modality (i.e., auditory-verbal or bilingual). The study included the mothers and teachers of 14 deaf children educated in auditory-verbal or bilingual programs. Two scales from a survey instrument, Profiles of the Hearing Impaired (Webster & Webster, 1995), were used. No significant differences between the teachers' and parents' evaluations were found. Gender, cochlear implantation, and communication modality were found to have no significant effect on the evaluations.  相似文献   

寄生虫     

J·H·法布尔  张明旭 《现代语文》2003,(17)

在八九月里,让我们找一个正对太阳的斜坡,那儿往往热得烫手,因为太阳已经把它快烤焦了。恰恰是这种温度像火炉一般的地方,我们可以得到很大的收获。这一带热土,往往是黄蜂和蜜蜂的乐土。它们往往在地下的土堆里忙着料理食物——这里堆上一堆象鼻虫、蝗虫或蜘蛛,那里一组组分列着蝇类和毛毛虫类,还有的正在把蜜贮藏在皮袋里、土罐里、棉袋里或是树叶编的瓮里。  相似文献

梭罗日记     

梭罗  H．D． 《同学》2007,(2)

1837年这一年梭罗从哈佛大学毕业,回到了故乡——马萨诸塞州的康科德。不久他就与另一位美国文学史上的非凡人物、住在邻近的拉尔夫·沃尔多·爱默生(拉尔夫·沃尔多·爱默生,1803—1882,美国散文家、思想家、诗人、演说家和美国19世纪超验主义文学运动的领袖。著有《论自然》、《人生的行为》等)有了密切的交往。也许部分要归功于爱默生榜样的作用,梭罗也开始了写作。他回到家乡后不久就开始写日记。当时写的日记只保存下来一部分,它们不仅包括作者个人的观察和一般的感想,还大量抄录他正在阅读的古典作家著作的段落——在某种程度上可以称作“备忘录”。此时他的文字风格还不够成熟,有一部分读起来颇为枯燥,但那不时闪烁的智慧的火花,却预示着一种完全个性化的、才华横溢的写作风格即将出现。  相似文献
