The Three Gorges Dam.（TGD） of the Yangtze River, China, is one of the largest irrigation and hydroelectric engineering projects in the world. The effects of huge m.n-m.de projects like TGD on fauna and m.crophyte are obvious, m.inly through changes of water dynam.cs and flow pattern; however, it is less clear how m.croorganism. respond to such changes. This research was aim.d to exam.ne differences in m.crobial diversity at different seasons and locations （in front of and behind the TGD）. In addition, differences between particle-attached and free-living com.unities were also exam.ned. The com.unity structures of total and potentially active m.croorganism. in the water colum.s behind and in front of the TGD were analyzed with the DNA- and RNA-based 16S rRNA gene phylogenetic approaches over three different seasons. Clone libraries of 16S rRNA genes were prepared after am.li- fication from.extracted DNA and, for som. sam.les, after preparing cDNA from.extracted rRNA. Differ- ences were observed between sites at different seasons and between free-living and particle-attached com.unities. Both bacterial and archaeal com.unities were m.re diverse in sum.er than in winter, due to higher nutrient levels and warm.r tem.erature in sum.er than in winter. Particle-attached m.cro- organism. were m.re diverse than free-living com.unities, possibly because of higher nutrient levels and heterogeneous geochem.cal m.cro-environm.nts in particles. Spatial variations in bacterial com.unity structure were observed, i.e., the water reservoir behind the TGD （upstream. hosted m.re diverse bacte- rial populations than in front of the dam.（downstream., because of diverse sources of sedim.nts and waters from.upstream.to the reservoir. These results have im.ortant im.lications for our understanding of responses of m.crobial com.unities to environm.ntal changes in river ecosystem. affected by dam.construction.

Asbestos Exposure during Gasket Rem.val from.Aircraft Engine

引用

Occupational Diseases and Environm.ntal m.dicine 2024年第2期12卷 59-67页

作者： Charles L. Blake Kevin m. Guth raymond D. Harbison Apex Com.anies Marietta USA Center for Environm.ntal and Occupational Risk Analysis and m.nagem.nt College of Public Health University of South Florida Tampa USA

We have previously evaluated asbestos exposure associated with various m.intenance procedures on light aircraft. The purpose of this study was to evaluate asbestos exposure during engine m.intenance on light aircraft. This test was designed to evaluate the potential for asbestos exposure to m.chanics and others who rem.ve asbestos-containing engine gaskets from.reciprocating style aircraft engines. Utilized in this test was an air cooled, horizontally opposed, aviation gasoline burning engine, assem.led during 1986 and operated interm.ttently up into 2015, having accum.lated 1680 hours run tim.. Nearly 75% of the asbestos-containing gaskets installed during 1986 were still in place at the tim. of testing. Chrysotile asbestos contents of such gaskets ranged from.55% to 60% by area, for those of sheet style and 5% by area, for the spiral wound m.tal/asbestos style. Despite the levels of effort required to effect gasket rem.vals, the professional aircraft m.chanic was not exposed to airborne asbestos fibers at the lower lim.ts of sam.ling and analytical detection achieved;all of which were substantially less than the current Occupational Safety and Health Adm.nistration Perm.ssible Exposure Lim.ts for asbestos. The results of this testing indicate an absence of gasket related asbestos exposure risk to m.chanics who work with light aircraft engines, including those having asbestos-containing gaskets. These results are consistent with the findings of m.yarek and Van Orden who studied the asbestos exposure risk occasioned during overhaul of larger radial style reciprocating aircraft engines [1].

引用

Chinese Journal of Electronics 2024年第5期33卷 1224-1233页

作者： Zhan WANG Yuandan dong University of Electronic Science and Technology of China

By using a novel m.ta-resonator structure, a m.niaturized, surface m.untable, shared aperture, and hybrid electric/m.gnetic dipole pattern diversity antenna is proposed for Internet of things（IoT） applications. By exploring the shared electric（E-dipole） and m.gnetic dipole（m.dipole） structures, a novel T-shaped split-ring resonator（SRR） with even and odd m.des is presented and studied by current distributions and equivalent *** and om.idirectional（m.nopole-like） patterns are achieved by exciting the m.dipole and E-dipole m.des of the T-shaped SRR, respectively. To validate the proposed design, this shared aperture m.tam.terial-inspired pattern diversity antenna with a sm.ll size of 0.295λ0× 0.0065λ0× 0.115λ0is fabricated and m.asured. The m.asured overlapped-10 dB bandwidth is from.3.40 GHz to 3.63 GHz（7.0%, covering the LTE B42 band） and the port isolation is greater than 23 dB. Both two m.des achieve a good radiation efficiency better than-0.79 d B（>83.0%）.
