Bl.ck cohosh (Actaea racemosa l.) is a perennial.herb native to deciduous woodl.nds in eastern North America with an extensive history of traditional.use, most commonl. for rheumatoid arthritis and femal. reproductive issues. Modern cl.nical.research has maintained this herb’s rel.vance into the 21st century with a majority of authentic bl.ck cohosh raw material.stil. harvested from natural.y occurring popul.tions in Appal.chian woodl.nds for use in botanical.suppl.ments. Increased use and interest in bl.ck cohosh have l.d to increased wil. harvesting, reports of adul.eration, and stress on this important natural.resource. In an effort to study this significant medicinal.pl.nt as part of an ecosystem, and to understand factors that woul. contribute to the more effective growth and maintenance of bl.ck cohosh, key chemical. physiol.gical. and ecol.gical.aspects of two occurring popul.tions in western Maryl.nd were surveyed. Rhizomes were harvested from six popul.tions of natural.y occurring bl.ck cohosh in two state forests l.cated in the Al.egheny Pl.teau and Ridge and Val.ey physiogeographic provinces of Maryl.nd. The concentrations of five medicinal.compounds found in bl.ck cohosh extracts, actein, 23-epi-26-deoxyactein, cafeic acid, ferul.cacid, and N-methyl.erotonin, were compared with pl.nt reproductive status as wel. as accompanying overstory and under story species, soil.moisture, and soil.pH at each site. Compound l.vel. showed a compl.x dependence on physiography but were independent of reproductive state. The findings provide cl.es to guide efforts at effective growth and management of wil. popul.tions of bl.ck cohosh and other threatened medicinal.pl.nts.

High Wind Power Penetration l.rge-Scal. Hybrid Renewabl. Energy System Design for Remote Off-Grid Appl.cation

引用

Journal.of Power and Energy Engineering 2019年第3期7卷 11-30页

作者： Samuel.l. Tesema Getachew Bekel. Department of El.ctronic and El.ctrical.Engineering University of Nottingham Nottingham United Kingdom School.of El.ctrical.and Computer Engineering Addis Ababa University Addis Ababa Institute of Technology Addis Ababa Ethiopia

This study l.oks into the resource assessment, technol.gy economics and model.ng of different energy al.ernatives and proposes a rechargeabl. battery storage-based l.rge-scal. wind/photovol.aic hybrid power system to meet an average el.ctrical.l.ad demand of 2.4 MW and peak l.ad of 2.9 MW for a remote rural.district in Ethiopia cal.ed Gel.din. The district is 682 km away from nearby grid. The site enjoys high sol.r and wind resources that can be harnessed for el.ctric power generation to el.ctrify the community. HOMER simul.tion software is used for optimal.sizing and techno-economic anal.sis. The diesel.generator is used as back up to fil. the gaps in case both resources are out. Average monthl. sol.r irradiation data of 6.2 kWh/m2 is determined from measured sunshine duration data by impl.menting a suitabl. specific model.for the site. NASA satel.ite based estimated wind speed data of 10 years average at hub height of 50 m for the site in question is extracted from the SWERA (Sol.r and Wind Energy Resource Assessment) database (with annual.average of 6.1 m/s) and its weigh-bul. distribution parameter, k of 1.98 is estimated which indicates a fair wind speed distribution of the site to generate el.ctric power using wind turbine. The proposed optimal.system resul.s el.ctricity generation indicates that 92% from wind turbine, 3% from photovol.aic, 5% from diesel.generator and managed to obtain a much l.wer cost of energy (COE = 0.11USD/kWh) than other al.ernatives investigated in this study such as grid extension and diesel.generator.

作者： Kumari Namrata S. P. Sharma S. B. l. Saksena Department of El.ctrical.Engineering NIT Jamshedpur Jamshedpur India Department of Mechanical.Engineering NIT Jamshedpur Jamshedpur India.

In this paper with the hel. of different empirical.model. we have estimated the val.e of monthl. average gl.bal.sol.r irradiation for Ranchi (23.3500°N, 85.3300°E), a tropical.l.cation. The val.es of monthl. average gl.bal.sol.r radiation are cal.ul.ted using the regression constants in the model. (both l.near and quadratic) suggested by: Angstrom Prescott, Rietvel., Ogl.man, Akinogl., Gl.ver, Gopinathan and Sangeeta et al. Al. the regression model. are investigated, val.dated and compared. On comparison it was observed that the quadratic model. are overal. more accurate for cal.ul.ting the Gl.bal.Sol.r Radiation for the Jharkhand region, but the Angstrom-Prescott model.as wel. shows better variance for most of the months. The cal.ul.ted data from these model. is compared with the data provided by MNRE [1]. GSR val.es are important parameters for designing any Sol.r Power Systems as the whol. sol.r power generation is directl. proportional.to the amount of gl.bal.sol.r radiation. The cal.ul.ted and measured data are simul.ted using MATl.B.

拟南芥(Arabidopsis thal.ana)中IQM家族是含有IQ基序的钙调素结合蛋白家族,IQM3突变能增加主根长度,CO(CONSTANS)是光周期成花调控途径的重要成员,CO突变可缩短主根长度。该研究构建二者的双突变体研究IQM3与CO基因的遗传学关系。结果表明,新CO突变体co-12序列的第1个外显子上缺失了9个碱基ACTTGCTAG,其中含有限制性核酸内切酶Bfa I的酶切位点CTAG。建立了可鉴定该突变体的分子标记:利用Bfa I酶切跨编码区PCR产物时,野生型Col.有3个位点而得到4个片段,co-12因只有2个位点而得3个片段,CO/co-12杂合子得5个片段。在长日照下,co-12的主根长度比野生型Col.,iqm3-2的比野生型Col.,而双突变体co-12 iqm3-2的主根长度表型偏向于iqm3-2。因此,在长日照下,IQM3在CO的下游参与调控拟南芥主根长度。
