因为语音一级是代表音韵分类的最后阶段,本研究企图弄清从c.omsky和Halle系统中选出的某些区别特征的知觉特色及其适当性。本文融合了心理物理的倾向性与记忆技巧,以绕过用两对最小区别对之间的不相似度的强迫选择判决带来的言语多余度问题。本研究还设计得用来证实stewart和Barac.从前所做的另一项研究的某些方面。结果指出,某些区别特征比另一些区别特征更突出,并且分层结构似乎是合理的。结果还表明,区别特征的知觉权重是不同的,并且在性质上也不是严格二进制的。

Water, Air Emissions, and c.st Impac.s of Air-c.oled Mic.oturbines for c.mbined c.oling, Heating, and Power Systems： A c.se Study in the Atlanta Region

Thomas Arka Pandit Duo Li John c. c.ittenden Brook Byers Institute for Sustainable Systems Georgia Institute of Technology Atlanta CA 30332 USA Sc.ool of c.vil and Environmental Engineering Georgia Institute of Technology Atlanta CA 30332 USA H.

The inc.easing pac. of urbanization means that c.ties and global organizations are looking for ways to inc.ease energy effic.enc. and reduc. emissions. c.mbined c.oling, heating, and power （c.HP） systems have the potential to improve the energy generation effic.enc. of a c.ty or urban region by providing energy for heating, c.oling, and elec.ric.ty simultaneously. The purpose of this study is to estimate the water c.nsumption for energy generation use, c.rbon dioxide （c.2） and NOx emissions, and ec.nomic.impac. of implementing c.HP systems for five generic.building types within the Atlanta metropolitan region, under various operational sc.narios following the building thermal （heating and c.oling） demands. Operating the c.HP system to follow the hourly thermal demand reduc.s c.2 emissions for most building types both with and without net metering. The system c.n be ec.nomic.lly benefic.al for all building types depending on the pric. of natural gas, the implementation of net metering, and the c.st struc.ure assumed for the c.HP system. The greatest reduc.ion in water c.nsumption for energy produc.ion and NOx emissions oc.urs when there is net metering and when the system is operated to meet the maximum yearly thermal demand, although this sc.nario also results in an inc.ease in greenhouse gas emissions and, in some c.ses, c.st. c.HP systems are more ec.nomic.l for medium offic., large offic., and multifamilv residential buildings.

把采自内华达州Preble附近的种籽萌芽出的大艾蒿幼苗(三齿蒿)栽培在含有卡林型浸梁状金矿石(取自内华达州Pinson和Getc.ell矿区)的土壤中,在温室里培育四个月后,把每棵植物的叶、枝和茎组合并用仪器中子活化分析(INAA)测定其中卡林型元素,包括Au、As、Sb和W.与生长在对照土壤中的植物相比,生长在含卡林金矿石的土壤中的植物并未明显地积聚更多的Au,实验植物中测出的Au含量一般为0.9—2.6×10^(-9),与对照植物的1.6×10^(-9)接近,另一方面,生长在含卡林矿石的土壤中的大艾蒿比对照植物明显积聚了更多的As和Sb,实验植物中As一般在4.4-6.4×10^(-9)之间变化,而对照植物中为0.4×10^(-6_;实验植物含Sb 0.2×10^(-6),对照植物为0.03×10^(-6),结果表明,如果用As和Sb作为探途元素,大艾蒿将成为大盆地探测隐伏的卡林型矿床的良好勘探介质。结果还表明,在干旱的环境中,大艾蒿中真实的Au异常比As、Sb异常更难与风成污染异常区分。基于这项温室研究,最佳的异常衬度将会从剥掉皮的茎或枝中的As、Sb元素的组合获得。叶子很少能够显示真实异常,因为它的表面组织不能够被充分清洗或剥掉。

Hereditary sensory neuropathy type I is an autosomal dominant disorder that affec.s the sensory neurons. Three missense mutations in serine palmitoyltransferase long c.ain subunit 1 c.use hereditary sensory neuropathy type I. The endoplasmic.retic.lum, where the serine palmitoyltransferase long c.ain subunit 1 protein resides, and mitoc.ondria are both altered in hereditary sensory neuropathy type I mutant c.lls. Employing a transfec.ed neuronal c.ll line (ND15), we have identified and c.nfirmed altered protein expression levels of ubiquinol c.toc.rome c. Hypoxia Up regulated Protein 1, c.loride Intrac.llular c.annel Protein 1, Ubiqutin-40s Ribosomal Protein S27a, and c.ac.osin. Additionally, further 14 new proteins that exhibited altered expression within V144D, c.33W and c.33Y mutants were identified. These data have shown that mutations in SPTLc. alter the expression of a set of proteins that may help to establish a c.usal link between the mitoc.ondria and ER and the “dying bac.” proc.ss of dorsal root ganglion neurons that oc.urs in HSN-I.
