A state-of-the-art review of solar passive building system for heating or cooling purpose

Frontiers in Energy 2016年第3期10卷 347-354页

The major portion of energy in a building is consumed by heating, ventilating, and air-conditioning （HVAC）. The traditional heating and cooling systems contribute greatly to the emission of greenhouse gases, especially carbon dioxide. Four different ways, i.e., Trombe wall, solar chimney, unglazed transpired solar facade, and solar roof, are adopted for solar heating. Similarly, two major ways, i.e., evaporative cooling and building integrated evaporative cooling are adopted for cooling of the building. Therefore, an attempt has been made in this paper to compile the developments of solar heating and cooling technologies in a building.

A series of reticulated Arabidopsis thaliana mutants were previously described. All mutants show a reticulate leaf pattern, namely green veins on a pale leaf lamina. They have an aberrant mesophyll structure but an intact layer of bundle sheath cells around the veins. Here, we unravel the function of the previously described reticulated EMS-mutant dovl （differential development of vascular associated cells 1）. By positional cloning, we identified the mutated gene, which encodes glutamine phosphoribosyl pyrophosphate aminotransferase 2 （ATase2）, an enzyme catalyzing the first step of purine nucleotide biosynthesis, dovl is allelic to the previously characterized cial-2 mutant that was isolated in a screen for mutants with impaired chloroplast protein import. We show that purine-derived total cytokinins are lowered in clovl and crosses with phytohormone reporter lines revealed differential reporter activity patterns in dovl. Metabolite profiling unraveled that amino acids that are involved in purine biosynthesis are increased in dovl. This study identified the mo- lecular basis of an established mutant line, which has the potential for further investigation of the interaction between metabolism and leaf development.

A Review of <i>Paulownia</i>Biotechnology: A Short Rotation, Fast Growing Multipurpose Bioenergy Tree

引用

American Journal of Plant Sciences 2013年第11期4卷 2070-2082页

作者： Niraj kumarmangalam Yadav Brajesh nanda Vaidya Kyle Henderson Jennifer Frost Lee Whitley Marshay Stewart Sadanand arun Dhekney Nirmal Joshee 1Agricultural Research Station Fort Valley State University Fort Valley USA Agricultural Research Station Fort Valley State University Fort Valley USA Department of Plant Sciences University of Wyoming Sheridan Research & Extension Center Sheridan USA Wesleyan College Macon USA

Paulownia is a genus of fast-growing and multipurpose tree species that is native to China. Due to their rapid growth and value in the timber market, many Paulownia species are cultivated in several temperate zones worldwide. Economic importance of Paulownia is increasing as new uses and related products are developed. It is also suitable as a lignocellulosic feedstock crop for the bioethanol industry in the Southeastern USA. A number of Paulownia species are valuable sources of secondary metabolites including flavonoids with high antioxidant activities. A high demand for planting material in domestic and international markets for afforestation and bioenergy production has necessitated the development of efficient micropropagation protocols for rapid and mass propagation of Paulownia. Over the past several decades, research on Paulownia species has been conducted to develop micropropagation, somatic embryogenesis and genetic transformation protocols for use in agroforestry and reforestation programs. Given the economic importance and current and potential future uses of Paulownia, this paper reviews the development of biotechnological approaches for plant propagation and genetic improvement, and antioxidant potential of secondary metabolites occurring in species.

肝脏损害是由于微循环障碍、肝细胞变性坏死而引起的肝功能异常,它影响到几乎每个年龄段人群肝脏细胞的重要生物活性,而常规用药来抑制肝脏损害是远远不够的。而且,由于对抗疗法所用药物往往具有肝毒性,反而加剧了肝脏功能的紊乱。为了寻找安全有效的替代药物,人们逐渐把目光转向了具有保肝作用的药用植物,并对其进行系统性的方法学研究和药用原理评估。药用植物治疗肝病具有悠久的历史,最早可追溯到公元前2100年的中国夏朝和古印度吠陀时期,但是能证明那个时期药用植物有效治疗肝病的证据却很难寻觅。本文旨在系统性地概述现今在临床治疗和实验研究中最常用以及最有效的保肝类药用植物。
