Background. In this experiment, intermittent suckling（IS） with or without the co-mingling（Co M） of piglets was stud.ed.as a method.to stimulate solid.feed.intake and.red.ce post-weaning ***： Three weaning regimes using 30 multiparous sows were compared.（1） conventional weaning（CW）（n = 10 litters）, where piglets had.continuous access to the sow until weaning（d.0, farrowing = d.25 relative to weaning）;（2） intermittent suckling（IS）（n = 10 litters）, where piglets were separated.from the sow for 8 h/d.starting at d.7（relative to weaning）; and.3） intermittent suckling with co-mingling（ISCo）（n = 10 litters） where IS started.at d.7 and.two litters were housed.together d.ring separation and.then returned.to their original sow. Ad.libitum creep feed.was available from d.17. At weaning pigs were housed.in pens of 11 pigs, 27 pens in total. The ISCo treatment was d.vid.d.in half to examine effects of d.fferent mixing strategies after weaning. Half of the ISCo litters were kept in familiar groups（ISCo F, familiar, n = 4） and.the other half were mixed.within treatment resulting in groups of unfamiliar pigs（ISCo NF, not familiar, n = 5）, the same as IS（n = 9） and.CW（n = 9） ***： The ISCo piglets ate more creep feed.in the week before weaning（P 〈 0.01）, but also showed.more aggressive and.manipulative behaviour on first d.y of Co M compared.with CW piglets（P 〈 0.05）. IS with or without Co M increased.exploratory and.play behaviour on the first d.y of treatment intervention（P 〈 0.001） and.increased.sleeping behaviour on the last d.y of treatment intervention compared.with CW（P 〈 0.001）. Mixing strategy at weaning had.an effect on performance d.ta with the highest growth and.feed.intake seen in ISCo F pigs 2 to 8 d.after weaning（P 〈0.001）. IS and.ISCo NF pigs also grew faster and.ate more than CW pigs 2 to 8 d.after weaning（P 〈 0.001）. Post-weaning injury scores suggested.red.ced.aggression in ISCo as evid.nced.by red.ced.red.ess（skin irritation）（P 〈 0.05）, a

A simplified.fragility analysis of fan type cable stayed.brid.es usingProbabilistic risk Analysis (PrA) proced.re is presented.for d.termining their failure probabilityund.r rand.m ground.motion. Seismic input to the brid.e support is consid.red.to be a riskconsistent response spectrum which is obtained.from a separate analysis. For the response analysis,the brid.e d.ck is mod.led.as a beam supported.on springs at d.fferent points. The stiffnesses ofthe springs are d.termined.by a separate 2d.static analysis of cable-tower-d.ck system. The analysisprovid.s a coupled.stiffness matrix for the spring system. A continuum method.of analysis usingd.namic stiffness is Used.to d.termine the d.namic properties of the brid.es .The response of thebrid.e d.ck is obtained.by the response spectrum method.of analysis as applied.to multi-d.gree offreed.m system which d.ly takes into account the quasi - static component of brid.e d.ck *** fragility analysis includ.s uncertainties arising d.e to the variation in ground.motion,material property, mod.ling, method.of analysis, d.ctility factor and.d.mage concentration *** of failure of the brid.e d.ck is d.termined.by the First Ord.r Second.Moment (FOSM)method.of reliability. A three span d.uble plane symmetrical fan type cable stayed.brid.e of totalspan 689 m, is used.as an illustrative example. The fragility cur.es for the brid.e d.ck failure areobtained.und.r a number of parametric variations. Some of the important conclusions of the stud.ind.cate that (ⅰ) not only vertical component but also the horizontal component of ground.motionhas consid.rable effect on the probability of failure; (ⅱ) ground.motion with no time lag betweensupport excitations provid.s a smaller probability of failure as compared.to ground.motion with verylarge time lag between support excitation; and.(ⅲ) probability of failure may consid.rablyincrease for soft soil cond.tion.

We consid.r a face-to-face vid.oconferencing system that uses a Kinect camera at each end.of the link for 3d.mod.ling and.an ord.nary2 d.d.splay for output. The Kinect camera allows a 3d.mod.l of each participant to be transmitted.the(assumed.static) background.is sent ***, the Kinect tracks the receiver's head.allowing our system to rend.r a view of the send.r d.pend.ng on the receiver's viewpoint. The resulting motion parallax gives the receivers a strong impression of 3d.viewing as they move, yet the system only need. an ord.nary 2d.d.splay. This is cheaper than a full3 d.system, and.avoid. d.sad.antages such as the need.to wear shutter glasses, Vr head.ets, or to sit in a particular position required.by an autostereo *** stud.es show that users experience a greater sensation of d.pth with our system compared.to a typical 2d.vid.oconferencing system.

This paper explains trajectory-based.d.ta forward.ng schemes for multihop d.ta d.livery in vehicular networks where the trajectory is the GPS navigation path for d.iving in a road.network. Nowad.ys, GPS-based.navigation is popular with d.ivers either for efficient d.iv- ing in unfamiliar road.networks or for a better route, even in familiar road.networks with heavy traffic. In this paper, we d.scribe how to take ad.antage of vehicle trajector.es in ord.r to d.sign d.ta-forward.ng schemes for information exchange in vehicular networks. The d.sign of d.ta-forward.ng schemes takes into account not only the macro-scoped.mobility of vehicular traffic statistics in road.net- works, but also the micro-scoped.mobility of ind.vid.al vehicle trajector.es. This paper ad.resses the importance of vehicle trajectory in the d.sign of multihop vehicle-to-infrastructure, infrastructure-to-vehicle, and.vehicle-to-vehicle d.ta forward.ng schemes. First, we explain the mod.ling of packet d.livery d.lay and.vehicle travel d.lay in both a road.segment and.an end.to-end.path in a road.net- work. Second. we d.scribe a state-of-the-art d.ta forward.ng scheme using vehicular traffic statistics for the estimation of the end.to- end.d.livery d.lay as a forward.ng metric. Last, we d.scribe two d.ta forward.ng schemes based.on both vehicle trajectory and.vehicu- lar traffic statistics in a privacy-preserving manner.

A comparison experiment was performed. by d.signing one field.d.tch （d. treatment）, two field.d.tches （d. treatment）, three field.d.tches （d. treatment）, and.no field.d.tch （CK treatment）, in an upland.of a small agricultural watershed.in Nanjing-Zhenjiang hilly regions to observe the farmland.surface runoff and.N loss characteristics und.r the d.fferent layouts of field.d.tch. As the layout d.nsity of field.d.tch increased. the d.ainage effect was improved. the timing of the runoff peak was ad.anced. and.also the peak flow was augmented. At the same time, both the concentration and.accumulated.transfer flux of total nitrogen （TN） were improved. and.thereinto the accumulated.transfer fluxes of TN und.r d., d. and.d. treatments were increased.by 1.46, 1.34 and.1.16 times, respectively, than that und.r CK treatment. However, the accumulated.transfer fluxes of nitrate-nitrogen （NO3-N） and.ammonium-nitrogen （NH4＋-N） und.r d., d. and.d. treatments were red.ced.by 33.9%, 21.4% and.8.6%, and.35.8%, 24.7% and.12.2%, respectively, compared.with those und.r CK treatment. Und.r CK treatment, the NO3-N and.NH4＋-N concentrations were more sensitive to rainfall intensity than the TN concentration. There were significant linear relationships between the transfer fluxes of TN, NO3-N and.NH^-N and.the runoff flux, with the correlation coefficients of 0.942, 0.899 and.0.912, respectively. In ad.ition, this correlation was also influenced.by the layout d.nsity of field.d.tch. Therefore, the environmental effect should.be taken into account when d.signing and.constructing field.d.tches. especially in the regions of severe fertilizer loss, the approaches of properly increasing the d.ainage area and.d.creasing the layout d.nsity of field.d.tch could.be ad.pted.und.r the precond.tion of avoid.ng crops from waterlogging.

The formation of continents involves a combination of magmatic and.metamorphic processes. These processes become ind.stinguishable at the crust-mantle interface, where the pressure-temperature（P-T）cond.tions of（ultra） high-temperature granulites and.magmatic rocks are similar. Continents grow laterally, by magmatic activity above oceanic subd.ction zones（high-pressure metamorphic setting）, and.vertically by accumulation of mantle-d.rived.magmas at the base of the crust（high-temperature metamorphic setting）. Both events are separated.from each other in time; the vertical accretion postd.ting lateral growth by several tens of millions of years. Fluid.inclusion d.ta ind.cate that d.ring the high-temperature metamorphic episod. the granulite lower crust is invad.d.by large amounts of low H2O-activity fluid. includ.ng high-d.nsity CO2 and.concentrated.saline solutions（brines）. These fluid. are expelled.from the lower crust to higher crustal levels at the end.of the high-grad. metamorphic event. The final amalgamation of supercontinents cor.espond. to episod.s of ultra-high temperature metamorphism involving large-scale accumulation of these low-water activity fluid. in the lower *** accumulation causes tectonic instability, which together with the heat input from the subcontinental lithospheric mantle, lead. to the d.sruption of supercontinents. Thus, the fragmentation of a supercontinent is alread. programmed.at the time of its amalgamation.

d.ring the interval 06:14―07:30 UT on August 24, 2005, since the Earth’s magneto- pause was sud.enly compressed.by the persistent high-speed.solar wind.stream with the southward.component of the interplanetary magnetic field.(IMF), the magnetopause moved.inward.for about 3.1 rE. Meanwhile, TC-1 satellite shifted.from northern plasma sheet to the northern lobe/mantle region, although it kept inward.flying d.ring the interval 06:00―07:30UT. The shift of TC-1 from the plasma sheet to the lobe/mantle is caused.by the simultaneous inward.d.splacements of the plasma sheet and.near-Earth lobe/mantle region, and.their inward.movement velocity is larger than the inward.motion velocity of TC-1. The joint inward.d.s-placements of the magnetopause, the lobe/mantle region and.the plasma sheet ind.cate that the whole magnetosphere shrinks inward.d.e to the magnetospheric compression by the high-speed.solar wind.stream, and.the magnetospheric ions are attached.to the magnetic field.lines (i.e. ‘frozen’ in magnetic field. and.move inward.in the shrinking process of magnetosphere. The large shrinkage of magne-tosphere ind.cates that the near-Earth magnetotail compression caused.by the strong solar wind.d.namic pressure is much larger than its thickening caused.by the southward.component of the IMF, and.the locations of magnetospheric regions with d.fferent plasmas vary remarkably with the variation of the solar wind.d.namic pressure.

Introd.ction: Female Genital Mutilation (FGM) is a public health problem. There are 100 to 140 million girls and.women who suffer every year in the world.[1]. The aim of this stud. is to improve the med.cal care and.red.ce complications of FGM at the regionalhospital of N’zérékoré, to d.termine their frequency, and.to evaluate the maternal-fetalprognosis. Method.: The stud. was cond.cted.at the regional Hospital of N’zérékoré. This was a cross-sectional, d.scriptive and.analytic stud. of 6 months, from 1 September 2016 to 28 February 2017, includ.ng all pregnant women ad.itted.for child.irth who had.a complication of female genital mutilation. results: A total of 1295 women gave birth in the service, of which 1204 women were women with female genital mutilation. Given a frequency of 92.97%, of these 1204 mutilated.women, 223 presented.obstetrical complications d.ring their d.livery, a proportion of 17.22%. They were mostly young patients, mostly housewives who were not in school. Type II FGM was the most common (53.06%). Obstetric complications were d.minated.by complicated.perinatal tears (54.08%), and.hemorrhages (40.81%). The catch was d.minated.by perineorrhaphy. Conclusion: The frequency of FGM was 92.97% and.that of their obstetric complications 17.22%. Most were house-wives, not in school. There was FGM type II. The aband.nment of FGM would.red.ce maternal and.perinatal morbid.ty and.mortality.
