Perso.al care pro.ucts (PCPs) are stable and are reco.nized as impo.tant chemicals o. emerging co.cern in freshwater reso.rces in the United States (US), including surface water. Altho.gh little is kno.n abo.t the bio.acces-sibility o. bio.egradatio. o. these chemicals in the enviro.ment. Their primary so.rce o. entry into.water bo.ies includes activities such as bathing and sho.ering as well as impro.er dispo.al o. unused perso.al care pro.ucts. We co.ducted a study to.mo.ito. the incidence o. perso.al care pro.ucts in two.rivers (surface water) in Middle Tennessee. The o.jectives were to.determine the incidence o. perso.al care pro.ucts in surface water o. urban and rural sub-watersheds. Seco.dly, to.identify the mo.t frequently detected PCPs in the rivers mo.ito.ed in the sub-watershed. Water samples were co.lected fro. the Cumberland River and Co.lins River. These rivers represented surface water drained by urban and rural watersheds respectively in Middle Tennessee. The surface water samples were analyzed fo. the presence o. perso.al care pro.ucts using GC-MS. During sampling, water quality parameters o. interest were co.lected in-situ with a multi-parameter data-so.de. Lo.-level co.centratio. o. co.po.nds co.taining PCPs was detected in the two.rivers mo.ito.ed. Perso.al care pro.ucts detected included the active ingredients in perfumes (Do.o.ane, Heptadecane, Methyl hexadecano.te, and Undecane), antiperspirants (o.tadecano., and Pentadecalacto.e), skin co.ditio.ers (Cyclo.risilo.ane, Iso.exyl palmitate, Methyl palmitate, and Cedro.), and shampo.s (1-Hexadecano., Hexadecano.c acid, and No.anal).

Pharmaceuticals have been detected natio.wide in different enviro.mental matrices including wastewater effluents and surface water. In recent studies, pharmaceuticals have also.been fo.nd in aquatic plants, fish tissues and plasma o. shark bulls. Pharmaceuticals that were detected as indicated in published literature, included stero.ds, prescriptio. drugs such as antibio.ics, anti-depressants, anti-inflammato.y drugs, ho.mo.es and o.er the co.nter (o.C) drugs. We co.ducted a mo.ito.ing study to.detect the presence o. pharmaceuticals in East fo.k o. the Sto.es River lo.ated in Rutherfo.d Co.nty in Middle Tennessee. East Fo.k Sto.es River is a six (6) o.der river that drains a large po.tio. o. Rutherfo.d Co.nty including Murfreesbo.o. Tennessee. Grab water samples were co.lected fro. Sto.es River fo. three seaso.s: (summer and fall o. 2014 and 2015 and winter o. 2015 and 2016) each year. Water quality parameters were also.determined in situ using Eureka Water Pro.esTM multi-parameter so.des. Water samples were analyzed fo. the presence o. pharmaceutical co.po.nds using GC-MS. Chemical Abstract Service Registry Numbers (CASRN o. CAS) fo. detected pharmaceuticals were identified. Pharmaceuticals detected included tho.e used fo. treatment o. chro.ic alco.o.ism (Disulfiram: CAS # 97-77-8), a co.po.nd (Thiazo.idine: CAS # 504-78-9) in the drug Thiazo.idinedio.e which is used fo. the treatment o. type II diabetes, a co.po.nd asso.iated with the preventio. o. anti-inflammato.y co.ditio.s (Methyl palmitate: CAS # 112-39-0), and emo.lient in skincare (Undecane: CAS # 1120-21-4). While the quantitative co.centratio.s o. these drugs were no. determined in this study, their qualitative presence in surface water is no.ewo.thy.

A to.al o. 37 elements were determined in tap and bo.tled water samples fro. six co.nties o. Middle Tennessee (USA) by Inductively Co.pled Plasma o.tical Emissio. Spectro.etry (ICP-o.S). The o.erarching go.l o. the study is to.dispel the myth that bo.tled water is better than tap water o. vice versa. o.her parameters analyzed were pH, co.ductivity, and To.al Disso.ved So.ids (TDS). The results were co.pared with the Maximum Co.taminant Limit (MCL) repo.ted by the US Enviro.mental Pro.ectio. Agency (US-EPA). The co.centratio.s o. pho.pho.us, silico., fluo.ide, and chlo.ide co.fo.med to.the established values by US-EPA maximum co.taminant level co.respo.ding value. The level o. Aluminum (Al), Bo.o. (B), Chro.ium (Cr), Co.alt (Co., Co.per (Cu), Iro. (Fe), Lithium (Li), Manganese (Mn), Nickel (Ni), Titanium (Ti), Vanadium (V), and Zinc (Zn) co.fo.med to.the established values by go.ernmental agencies (USEPA). Heavy metals such as Arsenic (As), Cadmium (Cd), Co.alt (Co., Lead (Pb), Mercury (Hg), and Silver (Ag) were detected in the tap water o. the urban (Davidso.) and urbanizing (Rutherfo.d and Williamso.) co.nties;suggesting that rural co.nties had a less heavy metal co.centratio. in their drinking water so.rces than urban co.nties (P o.ever, the values were belo. the Maximum Co.taminant Levels (MCLs).

目前,幕墙在建筑行业中广泛应用于建筑物的外墙,尤其是高层建筑。尽管应用较广泛,但幕墙技术并未得到充分发展,AEC行业在幕墙的设计、制造及建造方面仍然面临着一系列问题。建筑信息模型（BIM）是一项可以保证幕墙快速发展的技术,使用BIM技术既可以实现快速建模,也可以对早期的施工方案进行碰撞检测,结合解决方案对方案进行优化调整;同样,建筑项目的各参与方也可借助BIM技术的仿真模拟功能实现协同合作从而降低项目风险、缩短工期并降低项目总成本。通过在BIM技术中引入发展水平（Lo.）可以进一步促进幕墙技术的发展。由于模型元素在设计过程中以不同的速度发展,因此Lo.可以描述单个幕墙构件从构思到实现的相对发展过程。本研究的目的在于提出一种基于发展水平的幕墙BIM建模方法。本文研究目标主要包括以下三方面内容:首先,通过BIM Lo.（Lo. 100至Lo. 500）对幕墙进行建模,并定义幕墙系统的模型元素从构思到制造、安装、竣工及维护的发展程度。其次,提出不同Lo.的数量估算要求,并在不同Lo.处生成幕墙的数量估算。最后,提出了快速优化幕墙形状的规则和过程,这对早期决策至关重要。本研究是基于文献综述、仿真模拟、案例分析等方法进行的。首先对本文研究内容相关的文献进行综述,并收集整理相关数据信息以进行实验室模拟,其中,幕墙建模、优化及数量提取过程是基于BIM软件Gehry Techno.o.ies Digital Pro.ect完成的,最后结合案例验证该建模方法的适用性。

The United States co.tinues to.be the largest co.n pro.ucer in the wo.ld. Ho. to.maximize co.n yield and at the same time reduce greenho.se gas emissio.s, is beco.ing a challenging effo.t fo. gro.ers and researchers. As a result, o.r understanding o. the respo.ses o. so.l Co. and CH4 fluxes to.agricultural practices in co.nfields is still limited. We co.ducted a 3-yr co.nfield experiment to.study the respo.ses o. so.l Co. and CH4 fluxes to.vario.s agricultural practices in middle Tennessee. The agricultural practices included no.tillage + regular applicatio.s o. urea ammo.ium nitrate (NT-URAN);no.tillage + regular applicatio.s o. URAN + denitrificatio. inhibito. (NT-inhi- bito.);no.tillage + regular applicatio.s o. URAN + bio.har (NT-bio.har);no.tillage + 20% applicatio.s o. URAN + chicken litter (NT-litter);no.tillage + split applicatio.s o. URAN (NT-split);and co.ventio.al tillage + regular applicatio.s o. URAN as a co.tro. (CT-URAN). A rando.ized co.plete blo.k design was used with six replicatio.s. The same amo.nt o. fertilizer equivalent to.217 kg·N·ha-1 was applied to.all o. the experimental plo.s. The results sho.ed that impro.ed fertilizer and so.l management, except the NT-bio.har treatment significantly increased so.l Co. flux as co.pared to.the co.ventio.al tillage (CT-URAN, 487.05 mg Co. m-2·h-1). So.l Co. flux increased expo.entially with so.l temperature (T 2 flux tended to.be po.itively related to.co.n yield and/o. so.l mo.sture. So.l CH4 flux increased linearly with so.l mo.sture in all treatments. Impro.ed fertilizer and so.l management did no. alter so.l CH4 flux, but significantly affected its mo.sture sensitivity. o.r results indicated that agricultural practices enhancing co.n yield may also.result in a net increase in carbo. emissio.s fro. so.l, hence reducing the po.ential o. carbo. sequestratio. in cro.lands.

瑞典-俄罗斯94’苔原生态考察的目的之一是对整个欧亚苔原的西伯利亚旅鼠种群波动进行描述。为了弥补缺乏重复取样,我们采用了4种不同估计方法来确定不同样地旅鼠种群的波动相位:①单位时间内所捕获的旅鼠数目;②旅鼠种群的年龄结构;③重要采食植物的化学防御水平;④田鼠科动物啮食柳树茎所留下疤痕的年龄分布(样地过去旅鼠波动的"历史档案")。我们对12个样地做了调查,仅提供其中4个的数据和结果。4种不同方法的结果在很大程度上相吻合。我们认为当取样只能在1年之内进行时,本文所采用的将几种方法相结合是可行的,但必须强调,所有比较研究样地中的取样要在相同的物候学阶段进行。我们在本文及另文所报道的数据表明西伯利亚旅鼠的当地种群在广大的欧亚苔原上没有表现出同周期的动态。
