Development of an in situ loop-mediated isothermal amplification technique for chromosomal localization of DNA sequences

In situ loop-mediated isothermal amplification (in situ LAMP) combines in situ hybridization and loop-mediated isothermal amplification (LAMP) techniques for chromosomal localization of DNA sequences. In situ LAMP is a method that is generally more specific and sensitive than conventional techniques such as fluorescence in situ hybridization (FISH), primed in situ labeling (PRINS), and cycling primed in situ labeling (C-PRINS). Here, we describe the development and application of in situ LAMP to identify the chromosomal localization of DNA sequences. To benchmark this technique, we successfully applied this technique to localize the major ribosomal RNA gene on the chromosomes of the Zhikong scallop (Chlamys farreri).     

拉萨航路一次颠簸过程的成因分析和数值模拟

颠簸是成都—拉萨航路影响飞行安全与正常的重要因素。本文分析了2009年10月23日发生在拉萨航路太昭航段的两例颠簸事件,并利用WRF模式进行了数值模拟预报。结果表明,这是一次典型的晴空颠簸过程,在高空急流区边缘,冷暖平流交汇的梯度带上,上升和下沉气流的转换区域内产生了飞机颠簸。分析WRF模式计算得到的L_P颠簸指数,能够确定飞机颠簸发生的区域、高度和强度,具有一定的预报指示意义。      

高原机场的航空天气预报

按照民航管理局相关规定的划分,海拔高度1500米（4922英尺）及以上、低于2438米的是高原机场;海拔高度2438米（8000英尺）及以上的是高高原机场。西南地区高原机场有10个,高高原机场9个（其中2个在建）。
