Mapping QTLs on BTA6 affecting milk production traits in a Chinese Holstein population

To make marker-assisted selection (MAS) more effi-cient in improving economically important traits for farm animals, one important factor is to find markers linked to the quantitative trait loci (QTL) as closely as possible. So it is best to use the gene per se underlying the QTL. A whole genome scan for QTL is the prerequisite in the be-ginning, then mapping on some special important chro-mosomes, and then fine mapping in some target region on given chromosome aiming at gene cloning and c…     

Expression of reconstructive hFⅧ in the hrDNA by using hrDNA targeting vector

Our lab has constructed a new nonviral vector-hrDNA targeting vector（pHrneo）, pHrneo is a human derived vector that can target gene into human ribosomal DNA（hrDNA） locus. In this study, we inserted expression cassette of reconstructive hF Ⅷ （hFⅧ-BDDAK39） to pHrneo to construct targeting vector： pHrneo-BDDAK39. Through electroporation of pHrneo-BDDAK39 into HT1080 cells, we identified the homologous recombinants by PCR and Southen blotting, and tested the expression of hFⅧ- BDDAK39 in the hrDNA locus. The hFⅧ-BDDAK39 was successfully targeted into hrDNA locus of HT-1080 by pHrneo-BDDAK39, and the efficiency of site-specific integration was 2.0×10^-5. hFⅧ-BDDAK39 in hrDNA locus of HT-1080 is found to be able to express efficiently （32±5 ng·10^6 cells^-1 .24 h^-1）. Targeting vector pHrneo-BDDAK39 can find use in gene therapy for hemophilia.

小波变换用于数字图像相关法位移场的平滑处理

基于小波多分辨率分析，对数字散斑相关法获得的位移场进行平滑处理。将含噪声的位移场进行小波分解，获得在不同尺度上的小波系数；根据位移和噪声在频率上的区别，消除属于噪声的小波系数，从而实现噪声滤除；讨论了小波基的选择和去除属于噪声的小波系数关键技术问题，实验结果表明位移场的噪声得到了很好的滤除。此方法尤其适用于非平稳位移场噪声的平滑处理，小波变换在噪声滤除方面具有一定优势。

除雪机器人

一到冬天，我国北方许多城市的道路就会被积雪覆盖。为了不让积雪影响交通，环卫工人们总是辛苦地铲雪。如果机器人能帮他们除雪，那该有多好啊。为此，我想发明一种除雪机器人。这种机器人可以先将雪吸到“肚子”里的储雪盒中，

三色堇的育苗及栽培技术

三色堇又名蝴蝶花、猫脸花、鬼脸花,是堇菜科、堇菜属的两年生草本植物,现代F1代杂交种多作一年生栽培,学名为Viola Tricolor,英文名为Pansy,原产地为南欧,三色堇为冷季型植物,喜欢冷凉的气候环境.早期三色堇的耐高温能力较差,主要在秋季播种,应用于春季花坛.经过育种工作者的努力,选育出了许多更耐寒及耐高温的品种,目前已广泛栽培,因此现在的三色堇不仅适宜布置春季花坛,而且大量运用于秋冬季花坛,大大丰富了秋冬季花坛的色彩.
