印度瘿蚊六新种(双翅目:瘿蚊科)

本种近似菲律宾一种稷(Panicum carinatum)上的Lasioptera paniculi Felt,但触角的节数不同,雌18节,雄16节;雌触角各节的比例不同而较短;抱器基节中等粗,端节较细。其雌触角18节也相似于印度一种稷Panicum fluitans上的L.flui-tans Felt,但触角第五节远比端节长,产卵器短得多。     

TY21a口服伤寒活菌苗肠衣胶囊的大规模现场试验

<正> 在世界许多地区伤寒仍然是一种重要的疾病,并能造成旅游者的一种感染。大部份地区伤寒的发病率在5-19岁年龄组的儿童中最高。在控制伤寒的方案中以学校为基地的免疫接种是恰当的,因为学龄儿童代表着伤寒“俘虏”人群。 虽然热酚灭活和丙酮灭活的不经肠道的灭活全菌体伤寒菌苗提供了有价值的保护,但很少用于系统的控制伤寒计划中,因为它们的副反应高。 抗伤寒免疫接种中的一个重要进展是     

Delivery of Functionality in Complex Food Systems: Physically Inspired Approaches from Nanoscale to Microscale,Wageningen 18–21 October 2009

The Wageningen Delivery of Functionality symposium covered all aspects involved with food structural design to arrive at high-quality foods which meet demanding customer expectations and regulatory requirements. The symposium integrated aspects from the structural organization of foods at molecular and supramolecular scales to dedicated techniques required to describe and visualize such structures, the gastro-intestinal events and how to model these in a laboratory setting, and finally the impact those food structures and ingredients have on the consumer’s physiology and on the human perception. As an interdisciplinary platform, bringing together more than 160 researchers from academia and industry, the symposium meanwhile fulfills an important role in the food science community.
