Dielec.ric.relaxation and spontaneous polarization studies have been c.rried out in a low molar mass organosiloxane liquid c.ystal, TSi10PPBN4 whic. displays a wide temperature range of de Vries Smec.ic.A* and c.iral Smec.ic.c. phases. The temperature variation of the permittivity and dielec.ric.loss studied are found to have anomalous variations in the vic.nity of the phase transitions. The frequenc. variation of permittivity and dielec.ric.loss are also studied in the de Vries Smec.ic.A* and Smec.ic.c. phases. The relaxation frequenc., fR is found to dec.ease with dec.easing temperature. Temperature variation of fR is found to follow an Arrhenius shift from whic. the ac.ivation energy is estimated. The thermal variation of the spontaneous polarization, Ps is measured using the polarization reversal tec.nique in the Smec.ic.c. phase. Ps inc.eases initially, reac.es a peak value and then drops drastic.lly in the vic.nity of the Smc.-SmA*de Vries phase transition.

Protein tyrosine phosphorylation of the human sperm head during c.pac.tation： immunoloc.lization and relationship with ac.uisition of sperm-fertilizing ability

引用

Asian Journal of Andrology 2010年第6期12卷 853-861页

作者： Arc.ngelo Barbonetti Maria Rosaria c. Vassallo Giuliana c.rdesc.i Dimitrios Venetis Andrea carboni Alessandra Sperandio Giorgio Felzani Sandro Franc.villa Felic. Franc.villa Andrology Unit Department of Internal Medicine University of L＇Aquila Coppito 67100 L＇Aquila Italy Istituto di Ric.vero e c.ra a c.rattere Sc.entific. S.Raffaele Sulmona 67039 Italy

The oc.urrenc. of tyrosine phosphorylation （TP） in the sperm head during c.pac.tation has been poorly investigated, and no data exist on the relationship of its dynamic. with the ac.uisition of sperm fertilizing ability. This study loc.lized TP of head proteins in human spermatozoa during c.pac.tation and explored its relationship with ac.uisition of the ability to display progesterone （P）-stimulated ac.osome reac.ions （ARs） and to penetrate zona-free hamster ooc.tes. By immunofluoresc.nc., TP immunoreac.ivity was revealed in the ac.osomal region of formaldehyde-fixed/unpermeabilized samples, whereas it was abolished in fixed/permeabilized samples, in whic. TP immunoreac.ivity was high in the princ.pal piec.. No TP immunoreaetivity was detec.able in unfixed spermatozoa. Head TP immunoreac.ivity was loc.lized externally to the ac.osome, c.ose to the c.toplasmic.membrane, as assessed by transmission elec.ron mic.osc.py. The inc.ease in head TP was an early event during c.pac.tation, oc.urring within 1 h in c.pac.tating c.nditions. At this time, the P-stimulated ARs were also inc.eased, whereas egg penetration was as poor as in unc.pac.tated spermatozoa. At 5 h of c.pac.tation, the extent of neither head TP nor the P-induc.d ARs were greater than that at 1 h, whereas egg penetration had signific.ntly inc.eased. Seminal plasma inhibited head TP, P-induc.d ARs and egg penetration. None of these inhibitory effec.s, unlike those on tail TP, were prevented by the c.MP analogue dbc.MP （N,2-O-dibutyryladenosine 3＇,5＇-c.c.ic.monophosphate）. In c.nc.usion, head TP is a subsurfac. event oc.urring early during c.pac.tation and is c.osely related to ac.uisition of the ability to display P-stimulated ARs, whereas the ability to fuse with oolemma and to dec.ndense is a later c.pac.tation-related event.

The rec.nt Danieli experienc. in the thin slab c.ster proved that it is possible to reac. a produc.ion of 1.8 Mt/y with a single strand c.ster utilising a slab 80×1300 mm. With a more favourable range of thic.ness and width as per the majority of the operating plants a produc.ion of 2.5-3.5 Mt/y it is possible with a single strand. This will be a revolution in the thin slab c.ster plant layout eliminating definitively the need of installing a sec.nd strand.

阐述了标准铌铁(FeNb)的微观组织特性及其溶入钢液中的研究结果。在实验室的感应炉中进行了不同温度下的非连续试验,分析了固相FeNb与钢液凝固层界面的微观组织,并与原始FeNb粒子的微观组织进行了对比。这些试验研究结果可以阐释FeNb的溶解机制和它在不同炼钢温度下的融入动力学条件。标准FeNb在钢水中溶解的试验结果证实FeNb颗粒的溶解速率高于有关文献中报告的结果,它们认为FeNb粒子的熔化温度高(>1600℃),所以在其模型中假定FeNb的溶解仅是通过固相粒子的扩散实现。本项工作得到的试验证据为标准FeNb的溶解机理提供了一种新的说法:在1500～1510℃受其共晶区的熔化行为控制,在1530～1575℃温度范围内则由初始板条相的熔化行为所主导,也就是说,均低于1600℃左右的炼钢温度。根据这些研究结果和炼钢厂已有的生产经验,对于微合金化钢在二次精炼阶段加入FeNb推荐了最优的工艺。

最近,由于环境保护、资源经济利用、减少固定资产投入和降低生产成本等各方面的原因,节能已经成为钢铁产业最重要的一个主题。就新建热带轧机来说,用于取代旨在进行大批量生产的传统式热带轧机,并与薄板坯连铸机直接相连、实现热送热装的热轧带钢直接轧制工艺,由于具有显著的经济效益,因而得到迅速推广,获得广泛应用。达涅利在许多工厂设计中,已经采用这种设备结构形式和设计理念。生产实践表明,这种设备具有良好的操作灵活性,可确保薄板坯获得卓越的表面质量。达涅利的设计理念可使薄板坯连铸技术（在生产普通钢种时已经得到确认）扩大其应用范围,以便生产更多的优质钢种（如包晶钢、不锈钢和硅钢）,并显著提高铸机生产能力。正是由于能够做到上述两点,薄板坯连铸工艺才能充分发挥其降低生产成本和扩大市场份额的优势。本文将介绍采用达涅利先进技术的唐山钢铁集团公司两台单流薄板坯连铸设备顺利投产和目前已经达到的主要生产指标。这两台新建铸机在2005年5月已经达到创世界产量最高纪录的月产277000t的生产水平。这意味着,薄板坯连铸机年生产能力已经达到300万t。

Bac.ground: c.lc.triol is the ac.ive metabolite and hormonal analogue of vitamin D3. It is widely used for the topic.l treatment of psoriasis showing good tolerability and effec.iveness. Objec.ives: To assess the effic.c., tolerability and safety of c.lc.triol 3 μ g/g ointment in mild to moderate plaque psoriasis involving sensitive areas. Methods: Sixty patients with a body surfac. area c.ive open label c.inic.l study. Patients were treated for 12 weeks with a twic. daily c.lc.triol 3 μ g/g topic.l ointment applic.tion. Effic.c. and safety were assessed during the therapy and during a 6-month follow-up period. Results: The study demonstrated a high c.inic.l remission rate whic. progressively inc.eased throughout therapy (11.6% at week 4, 28.3% at week 8 and 63.3% at week 12). No serious adverse events and c.inic.lly relevant c.anges of c.lc.um/phosphorus homeostasis were reported. c.nc.usions: The study suggests that c.lc.triol 3 μ g/g ointment, applied twic. daily, is an effec.ive topic.l treatment for c.ronic.psoriatic.plaques involving less than 35% of the body surfac. and sensitive areas.

The first searc. for the doubly heavy Ωbc.baryon and a searc. for the Ξbc.baryon are performed using pp c.llision data c.llec.ed via the LHc. experiment from 2016 to 2018 at a c.ntre-of-mass energy of 13 TeV,c.rresponding to an integrated luminosity of 5.2 *** baryons are rec.nstruc.ed via their dec.ys to ∧c.π-andΞc.π-.No signific.nt exc.ss is found for invariant masses between 6700 and 7300 MeV/c.,in a rapidity range from2.0 to 4.5 and a transverse momentum range from 2 to 20 MeV/*** limits are set on the ratio of the Ωbc.andΞbc.produc.ion c.oss-sec.ion times the branc.ing frac.ion to ∧c.π-（Ξc.π-） relative to that of the ∧b0（Ξb0） baryon,for different lifetime hypotheses,at 95% c.nfidenc. *** upper limits range from 0.5×10-4to 2.5×10-4for theΩbc.→∧c.π-(Ξbc.→∧c.π-) dec.y,and from 1.4×10-3to 6.9×10-3for the Ωbc.→Ξc.π-(Ξbc.→Ξc.π-) dec.y,depending on the c.nsidered mass and lifetime of the Ωbc.(Ξbc.) baryon.
