基于VNTR技术的食用红甜菜不育系的选育

甜菜在世界糖料作物中占有重要地位,为选育提高育种效率,符合人们期望性状的优良品系,增加甜菜糖产量,分子辅助育种越来越被育种家们重视。而对于受到细胞质基因和细胞核基因控制甜菜雄性不育性的分子标记研究是近年来取得了较大突破。本实验是以食用红甜菜(工大食甜1号)为实验材料,利用数目可变的串联重复序列(VNTR)技术对其细胞质和细胞核育性类型进行鉴定,从中选育出了11株不育型甜菜。通过对其田间鉴定表明,选育的11株甜菜不育率稳定,不育率达到100%。

《山海经》佩饰的复原分析

《山海经》虽被不少人视为一部记录虚构故事的奇书,但其中的佩饰描写具有一定的写实性。基于神话《山海经》中关于中国古人佩饰的描写,结合文献记载和考古实物,对《山海经》中的佩饰进行复原分析。研究认为:在头饰方面,玉胜之原型是织机上的卷经轴;角饰“觡”源于鹿图腾,且必须与面具相组合,才能显露萨满的神秘感;冠不具有实用功能,但具有鲜明的政治性,其原型应具有商、周时期冠的特征;瞂饰是头盔,其造型体现了天圆地方的观念和鸟崇拜的痕迹。在耳饰方面,古人认为金环耳饰乃鬼之神所戴,具有辟邪之功能。在腰饰方面,玉璜是贵族佩带之物,其纹样体现求仙之气;剑为男子所佩之物,佩剑的社会风尚是自上而下形成的。     

苏州古典园林纹样涵义的追溯

Geologic Workflows: The Metamorphosis of the Great Rock

Creating a series of inspirational museum spaces inside an irregularly shaped void at the heart of a massive artificial rock formation is no everyday task. To fulfil the dream that had driven construction of the Great Rock at Budapest Zoo & Botanical Garden over a century ago, and to make the most of the space available, local firm PLANT – Atelier Peter Kis devised an innovative workflow that began with 3D scanning of the decaying concrete structure. Architect Péter Kis and landscape architect Sándor Bardóczi describe it.     

Effects of an external electric field on the collection efficiency of air filters: Filtration mechanisms with an external e-field

An external electric field was applied on the filter to improve its collection efficiency, and the collection efficiencies of the different filters under various conditions were evaluated. Dominant electrical filtration mechanisms for each condition were investigated using experimental and theoretical approaches. Four types of air filters were used as test filters: a charged fiber filter, a low-grade filter with 50% collection efficiency in the most penetration particle size (MPPS) zone, and two high-grade filters with more than 95% collection efficiency in the MPPS zone. Three different particle charge states—neutralized, single-charged and uncharged—were considered. For neutralized particles, the external electric field led to a 14.5%p. and 2.5%p. increase in the collection efficiencies of the low-grade filter and charged fiber filter, respectively. With the electric field, the collection efficiency of the low-grade filter increased by 30%p. for single-charged particles. The electric field also affected the collection efficiencies of the charged filter and high-grade filters, but the effect was not significant. For uncharged particles, the electric field did not lead to a remarkable increase in the collection efficiencies of any of the filters. Through experimental and theoretical analysis, it was found that the polarization force imposed on the charged fiber was the dominant factor for the charged fiber filter regardless of application of the external electric field. The Coulombic force imposed on the electric field was the dominant factor for the low-grade filter, while both the Coulombic and the polarization forces affected the collection efficiency of the high-grade filter.
