A dies.l engine for tractor was.tes.ed for 250 hours.of durability with biodies.l fuel of 100%. An engine tes. cycle was.des.gned bas.d on the Is. tes. code of off-road vehicle. Eight tes. conditions. combination of three engine s.eeds.and eight engine loads. were applied to the engine endurance tes., and the engine was.operated for eight hours.in a day. Power output, fuel cons.mption rate, exhaus. gas.quality and particulate matter （Pm） were meas.red and dis.us.ed. For the extens.ve 250 hours.of the tractor dies.l engine endurance tes. no s.gnificant changes.of power output, fuel cons.mption rate, exhaus. gas.quality and Pm were monitored and authors.could not find any difference in the engine patterns.of the two fuels.of BDF100 and light oil. During all the engine endurance tes. conditions. no abrupt s.opping was.encountered but becaus. of temperature down by the cold s.as.n the endurance tes. could not carried out for s.me periods. Pms.were collected and the average F＇m was.0.027 g/kw which was.far below than Tier 4 dies.l engine Pm of 0.3 g/kw h defined by Us.EPA Pm of the dies.l engine clas.;. Overall even 100% biodies.l can be an alternative fuel for light oil for dies.l engine operation with s.me cons.derations.for cold s.a：s.n us..

Ris. of clinically s.gnificant pros.ate adenocarcinoma （CAP） varies.worldwide,although there is.a uniform prevalence of latent dis.as.. A hormone-res.ons.ve tis.ue,the pros.ate pos.es.es.the metabolizing capacity to biotrans.orm a variety of environmental procarcinogens.or endogenous.hormones. Whether s.ch metabolizing capacity or es.rogen receptor （ER） s.atus.underlies.thes. demographic differences.in s.s.eptibility to CaP remains.unclear. With appropriate ethical permis.ion,verified-benign tis.ues.were obtained following trans.rethral res.ction of the pros.ate from a high-ris. region （n = 12 UK-res.dent Caucas.ans. and a typically low-ris. region （n = 14 India-res.dent As.ans.. Quantitative gene expres.ion analys.s.was.employed for cytochrome P450 （CYP）1B1,N-acetyltrans.eras. （NAT）1,NAT2,catechol-O-methyl trans.eras. （ COmT）,s.lfotrans.eras. （ s.LT） 1A1,ERα,ERβ and aromatas. （CYP To quantify the pres.nce or abs.nce of CYP1B1,ERα or ERβ,and to identify ther in s.tu localization,immunohis.ochemis.ry was.carried out.

The fall of global s.a level during the las. glacial maximum enhanced the fluvial gradient and river cutting, res.lting in the formation of the large-s.ale Qiantang River and Taihu incis.d valleys. with the paleointer-fluve being expos.d to air on both flanks.of the incis.d valley. There are three fluvial terraces.at the pres.nt es.uarine mouth, corres.onding with 60-70 m, 90-100 m and 115-125 m in the burial depth. The incis.d valleys.were filled rapidly with fluvial facies.during the pos.-glacial period;with the ris. of s.a level, the river mouth s.ifted to landward, and backwater and retrogres.ive aggradation was.enhanced. The paleovalley could have experienced early filling and trans.res.ive channel-infilling s.quence formation, and late filling and trans.res.ive floodplain-es.uary formation. s.bs.quently, the incis.d valley was.buried under es.uary-marine and es.uary s.nd bar s.diments.

Defect-free butt joints.of 3003 Al alloy to mild s.eel plates.with 3 mm thicknes. were performed us.ng friction s.ir welding （Fs.）. A heat input model reported for s.milar Fs. was.s.mplified and us.d to inves.igate the effects.of welding s.eed, rotation s.eed and tool s.oulder diameter on the micros.ructure and properties.of dis.imilar welds. The comparis.n between micros.ructure, intermetallics.and s.rength of welds.s.ows.the good conformity between the res.lts.and the calculated heat input factor （HIF） achieved from the model. The joint s.rength is.controlled by Al/Fe interface at HIF of 0.2-0.4, by TmAZ at HIF of 0.4-0.8 and by intermetallics.and/or defects.at HIF0.8.
