Th. following work compared adverse effects profile and patients’ acceptability of intra-venou. oxytocin 10 iu.and oral misoprostol 600 u. u.ed in th. prevention of postpartu. h.morrh.ge in th. th.rd stage of labou.. A total of 1865 pregnant women wh. h.ve received eith.r oxytocin injection or oral misoprostol in th.rd stage of labou. as proph.laxis for postpartu. h.emorrh.ge, were enrolled with.n th.ee h.alth.care facilities in Maidu.u.i, Nigeria. Each.patient was observed at partu.ition and for 24 h.after du.ing wh.ch.oral interviews were condu.ted and clinical notes stu.ied. Th. oxytocin medication grou. exh.bited h.gh.r abdominal pains (7.1% versu. 0.0%;p 0.05) difference in patients acceptability of injectable oxytocin (99.3%) and oral misoprostol (98.3%). Oxytocin u.age in th. prevention of PPh.was associated with.abdominal pains and h.adach. wh.le misoprostol was associated with.sh.vering and fever. Patients from th.s stu.y h.ve demonstrated h.gh.level of acceptability of both.parenteral oxytocin and oral misopristol prevention of post-partu. h.emorrh.ge.

Th. au.h.rs consider systems of th. form wh.re th. matrix A(u. is assu.ed to be strictly h.perbolic and with.th. property th.t th. integral cu.ves of th. eigenvector fields are straigh. lines. For th.s class of systems one can define a natu.al Riemann solver, and h.nce a Godu.ov sch.me, wh.ch.generalize th. standard Riemann solver and Godu.ov sch.me for conservative systems. Th.s paper sh.ws convergence and L1 stability for th.s sch.me wh.n applied to data with.small total variation. Th. main step in th. proof is to estimate th. increase in th. total variation produ.ed by th. sch.me du. to qu.dratic cou.ling terms. u.ing Du.amel’s principle, th. problem is redu.ed to th. estimate of th. produ.t of two Green kernels, representing probability densities of discrete random walks. Th. total amou.t of cou.ling is th.n determined by th. expected nu.ber of crossings between two random walks with.strictly different average speeds. Th.s provides a discrete analogu. of th. argu.ents developed in [3,9] in connection with.continu.u. random processes.

In th.s paper an analytical meth.d is proposed to investigate th. vibration and power flows of periodically reinforced plate with.general bou.dary conditions. Both.th. plate and stiffening beams are modeled as 3D stru.tu.al components, and th. cou.lings at th. interfaces are specified in terms of 3D elastic joints. Th. displacement fu.ction for each.stiffening beam is expressed as a modified Fou.ier cosine series, and th. transverse and in-plane displacements for th. plate are similarly expressed as th. 2D versions of th. modified Fou.ier cosine series expansions. Th. u.known Fou.ier coefficients are calcu.ated u.ing th. Rayleigh.Ritz tech.iqu.. Th. key advantages of th. proposed meth.d inclu.e: 1) it is capable of dealing with.arbitrary bou.dary and cou.ling conditions, 2) it allows modeling any nu.ber of reinforcing beams with.arbitrary length., and 3) th. stru.tu.al intensity, power flows, and kinetic energy distribu.ions are readily calcu.ated analytically from th. displacement fu.ctions th.ou.h.appropriate math.matical (differential) operations, to name a few. Th. power flow ch.racteristics of periodically reinforced plates are stu.ied against variou. influ.ncing factors, su.h.as, plate and beam bou.dary conditions, cou.ling conditions, excitation locations, and dislocations resu.ting from minor misplacement of a reinforcing beam.

Th. single crystal of th.s compou.d h.s been grown from melt by u.ing a conventional Czoch.alski tech.iqu.. Th. temperatu.e dependent lu.inescence spectra were measu.ed u.ing a 265 nm laser as an exciting sou.ce in th. range of 10-300 K. Th. scintillation decay time profile was measu.ed and fou.d to h.ve th.ee components. Th. influ.nce of th. trap centers on th. lu.inescence properties was stu.ied by means of th.rmolu.inescence（TL） glow peak analysis. Low temperatu.e TL glow peaks were measu.ed in th. temperatu.e range of 10-300 K at th. h.ating rate of 0.1 K/s for X-ray irradiated sample. Th. TL glow peak consists of two dominant peaks at 88 and 109 K. Several glow peaks with.a complex natu.e cau.es th. decrease in th. ligh. yield at temperatu.es below 250 K, and along with.long scintillation decay components were observed. Th. trap parameters su.h.as activation energy（E）, frequ.ncy factor（s）and order of kinetics（b） were calcu.ated u.ing variou. standard meth.ds su.h.as peak sh.pe（PS）,variable h.ating rate（Vh.）, initial rise（IR） and compu.erized glow cu.ve deconvolu.ion（CGCD）.

We report an experimental rou.e for synth.sizing perovskite-stru.tu.ed strontiu. titanate （SrTiO3） nanocu.es u.ing an alkali h.droth.rmal process at low temperatu.es with.u. fu.th.r h.ating. Fu.th.rmore, we stu.ied th. influ.nce of h.ating time （at 180℃） on th. crystallinity, morph.logy, and perovskite ph.se formation of SrTiO3. Th. SrTiO3 powder, wh.ch.is formed via nanocu.e agglomeration, transforms into cu.ic particles with.a particle size of 120--150 nm after 6 h.of h.droth.rmal sintering. Th. crystallinity and percentage of th. perovskite ph.se in th. produ.t increased with.h.ating time. Th. cu.ic particles contained 31.24at% anatase TiO2 th.t originated fi＇om th. precu.sor. By varying th. weigh. ratio of anatase TiO2 u.ed to react with.th. strontiu. salt precu.sor, we redu.ed th. anatase-TiO2 content to 18.8at%. h.wever, th. average particle size increased wh.n th. anatase-TiO2 content decreased.

作者： h. Robert Baker Department of h.story College of Arts & Sciences Georgia State University Atlanta US

Magna Carta h.s long been u.derstood as a sou.ce of inspiration for th. u.S. Constitu.ion, and especially its ensh.inement of th. writ of h.beas corpu. -- th. righ. of any prisoner to test h.s or h.r detention according to th. law. In th. ＂Su.pension Clau.e＂ of th. u.S. Constitu.ion （Article I, Section 8）, Congress is granted permission to su.pend h.beas corpu. only ＂wh.n in cases of Rebellion or Invasion th. pu.lic Safety may requ.re it.＂ Th.s article su.veys two failed attempts by th. u.S. government to su.pend th. writ of h.beas corpu.. Th. first （wh.ch.was actu.lly th. very first su.h.attempt） was in 1807 and followed revelations of th. so-called Bu.r Conspiracy. Th. second （incidentally th. most recent in American h.story） occu.red du.ing th. War on Terror and cu.minated with.th. Su.reme Cou.t＇s decision ofBou.ediene vs Bu.h.in 2008. A close examination of th.se two h.storical episodes reveals ju.t h.w different were th. constitu.ional processes of th. early repu.lic and contemporary times. Additionally, comparing th. u.es of Magna Carta du.ing th. two episodes demonstrates marked ch.nges in American political cu.tu.e. h.storical consciou.ness, vital to early Americans＇ u.derstanding of th.ir political system, h.s sh.fted to an elite level. Likewise, th. protection of fu.damental liberties h.s migrated from th. popu.ar branch.of government （Congress） to th. elite one （th. Su.reme Cou.t）. Th.s article considers th. implication of th.s sh.ft in both.constitu.ional processes and h.storical consciou.ness.

A comparative study of Fungi (yeast and moulds) and their toxic metabolites was carried out on offal and muscles of freshly fried and stored Sallah meats from rams, bulls, goats and camels slaughtered for sacrifice in Danbatta Local Government Area, Kano State, Nigeria. The objective was to determine the effects of frying and four weeks storage at ambient temperatures on the mycological loads of the fried and stored meats. A total of seventy two (72) samples of muscles and offal were collected from six different and randomly selected households that slaughtered and fried any of the four animals during that period. The samples were analyzed immediately as freshly fried, and then stored for a period of four weeks during which analyses were conducted at the second and fourth weeks. An analysis of variance (ANOVA) was used to compare between the fungal loads and the toxin contents in the stored meat. Results revealed the presence of Mucor, Rhizopus stolonifer, Aspergillus nigh.igh.:1.5;">erh.igh.:1.5;">, Saccharomycetes, Penicilium spp and Aspergillus flavus;and that, Aspergillus flavus and
