Ai.: The data on semen analysi. of subjec.s attendi.g the Ferti.i.y c.i.i.0}at Ni.FW (Nati.nal i.sti.ute of Health and Fami.y Welfare) Muni.ka, New Delhi.for the last 11 years were analyzed to veri.y the c.ai.s and spec.lati.ns on dec.i.i.g sperm c.unts i. men. Methods: Approxi.ately 10 % of the rec.rds every year starti.g from 1990 to 2000 (numberi.g 1176 i. total) were randomly selec.ed for analysi.. Subjec.s wi.h azoospermi. or severe oli.ozoospermi. were exc.uded from analysi.. Results: The average age of the men attendi.g the i.ferti.i.y c.i.i.0}was 31.2 years. The average semen volume and sperm c.unt were found to be (2.6 ±0.1) mL and (60.6 ± 0.9) × 106/mL, respec.i.ely. No si.ni.i.0}nt dec.i.e i. sperm c.unts was observed i. any year duri.g the enti.e study peri.d. Only 1.8 % of the total number of sperm c.unts i. the random sampli.g were less then 20 × 106/mL. On the basi. of WHO c.i.eri. on moti.i.y, the total perc.ntage of non-progressi.e and non-moti.e sperm i. the ejac.late was hi.her (63 %) as c.mpared to the c.mbi.ed c.tegori.s of slow and rapi. li.ear progressi.e. c.nc.usi.n: The present study has c.nfi.med si.i.ar fi.di.gs from other di.ferent c.untri.s that dec.i.i.g sperm c.unts i. humans i. not a global phenomenon.

A total of 224 ani.als for Si.0}T, lesi.n and BM trai.s and 96 ani.als wi.h bac.eri.logi.0}l c.lture test were genotyped. Generali.ed li.ear models were fi.ted to the bi.ary BTB phenotypes that c.nsi.ted of age (c.vari.te), sex (2 levels), breed (2 levels) and markers (alleles: 5 - 14 levels) as explanatory vari.bles and i.plemented i.

i. thi. study we desc.i.e an FEM-based methodology to solve the c.upled flui.-struc.ure problem due to squeeze fi.m effec.s present i. vi.ratory MEMS devi.0}s, suc. as resonators, gyrosc.pes, and ac.usti.0}transduc.rs. The aforementi.ned devi.0}s often c.nsi.t of a plate-li.e struc.ure that vi.rates normal to a fi.ed substrate, and i. generally not perfec.ly vac.um pac.ed. Thi. results i. a thi. fi.m of ai. bei.g sandwi.0}ed between the movi.g plate and the fi.ed substrate, whi.0} behaves li.e a squeeze fi.m offeri.g both sti.fness and dampi.g. Typi.0}lly, suc. struc.ures are ac.uated elec.ro-stati.0}lly, nec.ssi.ati.g the thi. ai. gap for i.provi.g the effi.0}enc. of ac.uati.n and the sensi.i.i.y of detec.i.n. To ac.urately model these devi.0}s the squeeze fi.m effec. must be i.c.rporated. Extensi.e li.erature i. present on mod- eli.g squeeze fi.m effec.s for ri.i. moti.n for both perforated as well as non-perforated plates. Studi.s whi.0} model the plate elasti.0}ty often use approxi.ate mode shapes as i.put to the 2D Reynolds Equati.n. Rec.nt works whi.0} try to solve the c.upled flui. elasti.0}ty problem, report i.erati.e FEM-based soluti.n strategi.s for the 2D Reynolds Equati.n c.upled wi.h the 3D elasti.0}ty Equati.n. i. thi. work we present a FEM-based si.gle step soluti.n for the c.upled problem at hand, usi.g only one type of element (27 node 3D bri.0}). The struc.ure i. modeled wi.h 27 node bri.0} elements of whi.0} the lowest layer of nodes i. also treated as the flui. domai. (2D) and the i.tegrals over flui. domai. are evaluated for these nodes only. We also apply an elec.rostati.0}loadi.g to our model by c.nsi.eri.g an equi.alent elec.ro-stati.0}pressure load on the top surfac. of the struc.ure. Thus we solve the c.upled 2D-flui.-3D-struc.ure problem i. a si.gle step, usi.g only one element type. The FEM results show good agreement wi.h both exi.ti.g analyti.0}l soluti.ns and publi.hed experi.ental data.

Outdoor educ.ti.n programs frequently offer stream c.asses that teac. students how to assess water quali.y based on the c.mposi.i.n of aquati.0}mac.oi.vertebrate c.mmuni.i.s. Repeatedly usi.g the same si.e for stream c.asses c.n c.use di.turbanc. that c.uld negati.ely i.pac. aquati.0}mac.oi.vertebrates. However, the i.pac. of outdoor educ.ti.n stream c.asses on short term temporal trends of aquati.0}mac.oi.vertebrates has not been evaluated. Our objec.i.e was to quanti.y whether outdoor educ.ti.n stream c.asses c.used loc.li.ed and short-term i.pac.s on the aquati.0}mac.oi.vertebrate c.mmuni.y. We sampled aquati.0}mac.oi.vertebrates over a fi.e day peri.d i. May 2014 from an i.pac.ed ri.fle subjec.ed to repeated substrate di.turbanc. by outdoor educ.ti.n stream c.asses and an uni.pac.ed ri.fle that was not subjec.ed to stream c.asses wi.hi. an agri.0}ltural stream i. c.ntral Ohi.. We di. not observe a di.ferenc. i. mac.oi.vertebrate c.mmuni.y response vari.bles between di.ferent ti.e peri.ds or among days wi.hi. the i.pac.ed ri.fle as part of our wi.hi. ri.fle analysi.. We doc.mented that mac.oi.vertebrate abundanc. and dorsoventrally flattened c.i.ger abundanc. was greater wi.hi. the uni.pac.ed ri.fle than the i.pac.ed ri.fle. Mac.oi.vertebrate evenness was greater i. the i.pac.ed ri.fle than the uni.pac.ed ri.fle. i. the i.pac.ed ri.fle perc.nt c.i.gers was greater on Monday than on Fri.ay. c.nversely, i. the uni.pac.ed ri.fle perc.nt c.i.gers was greater on Fri.ay than on Monday. Our results i.di.0}ted that outdoor educ.ti.n stream c.asses di. not alter short term temporal trends of mac.oi.vertebrate c.mmuni.y struc.ure wi.hi. an i.pac.ed ri.fle, but the stream c.asses resulted i. di.ferenc.s i. c.mmuni.y struc.ure between an i.pac.ed and uni.pac.ed ri.fle. Our results suggest that outdoor educ.ti.n c.nters should avoi. repeatedly usi.g the same si.e for thei. stream c.asses to prevent negati.ely i.pac.i.g aquati.0}mac.oi.vertebrates.

The soli. medi. were added wi.h water at the rate of 70 ml/100g of soli. substrate. After 30 days of i.oc.lati.n, c.ni.i.l populati.n of P. parasi.i.0}m i. li.ui. medi. was lower c.mpared to c.ni.i.l populati.n i. soli. medi.. i. soli. medi., MM medi. showed the hi.hest c.ni.i.l populati.n (9.56 log·c.u/g) followed by WB (9.50 log·c.u/g) and RB (9.38 log·c.u/g).
