Poly Laevo Lac.ic.Ac.d (PLLA), in spite of being an exc.llent bioplastic. has exorbitantly high m.rket pric. due to the high c.st of raw m.terial (lac.ose, gluc.se, suc.ose). Henc., its m.nufac.ure is being attem.ted starting from.waste effluents suc. as c.eese whey and m.lasses. Earlier studies on the sam. in fluidized bed and sem.fluidized bed biofilm.reac.ors yielded enc.uraging results. The present study therefore involves design and analysis of inverse fluidized bed biofilm.reac.ors for lac.ic.ac.d synthesis. The perform.nc. features of the bioreac.or have been studied both m.them.tic.lly as well as experim.ntally. The inverse fluidized bed biofilm.reac.or has been found to provide m.re than 75% c.nversion of suc.ose/lac.ose even at high c.pac.ties (high feed flow rates) exc.eding 56,000 L/hr, within a reasonably low reac.or volum.. The frac.ional substrate c.nversion inc.eases, though sluggishly, with inc.ease in feed flow rate due to bed expansion and also with inc.ease in c.ll m.ss c.nc.ntration in biofilm.due to enhanc.m.nt in intrinsic.rate of bioc.nversion. The inverse fluidized bed biofilm.reac.or of proposed design c.uld be safely rec.m.ended for the c.m.erc.al synthesis of polym.r grade lac.ic.ac.d from.waste effluents suc. as c.eese whey and m.lasses. The low operating c.st of the bioreac.or (due to downflow m.de of operation) enhanc.s the ec.nom. of the proc.ss. This would also help in signific.ntly lowering the m.rket pric. of the green plastic.(PLLA) and shall prom.te its large sc.le m.nufac.ure and utilisation.

In the present work, tilted global solar irradianc. data are presented and analysed, m.asured for a period of 1 year on the c.m.us of Bahrain Polytec.nic. Kingdom.of Bahrain, from.both a fixed photovoltaic.panel and a m.ving one via a two-axis solar trac.er. The fixed panel fac.s south with an angle of 26 degrees with respec. to the horizontal, c.inc.ding with the loc.l geographic.l latitude. The sec.nd panel is m.ved by two m.tors, c.ntrolled by a global positioning system.and suitable software so that the Sun's rays are perpendic.lar to the panel surfac.. A pyranom.ter is installed on eac. panel, rec.rding the tilted global solar irradianc., stored by using a data logger. The analysis of the data obtained shows a 33% solar energy gain on an annual basis for the m.ving panel (2780 versus 2088 kWh/m. on the fixed panel). m.re im.ortantly, in June, when the energy dem.nd in Bahrain is elevated due to the inc.eased residential c.oling loads, the solar energy rec.ived by the m.ving panel is 54.7% higher c.m.ared with that of the fixed panel. On a perc.ntage basis, the inc.ease in solar energy from.the m.ving panel is profound in the early m.rning and late evening hours. m.reover, the reduc.ion in the solar energy rec.ived by the fixed panel from.m.y to June does not appear in the m.ving panel bec.use of the adjustable orientation of the latter. Throughout the year, the m.an daily solar power varies between 0.37 and 0.56 kW/m. for the fixed panel, and 0.45 and 0.70 kW/m. for the m.ving panel. In winter, solar energy fluc.uations are elevated due to erratic.weather c.nditions that present a peak standard deviation of 28% of the c.rresponding m.an. The data presented are useful for potential solar investm.nts in Gulf c.untries. Tilted global solar irradianc. data are m.asured and analysed for a period of 1 year on the c.m.us of Bahrain Polytec.nic. Kingdom.of Bahrain, from.both a fixed photovoltaic.panel and a m.ving one via a two-axis solar trac.er. Graphic.l Abstrac.

A 63-year-old m.n with diabetes and asym.tom.tic.c.ronary artery disease developed refrac.ory ventric.lar arrhythm.a at 20 hours at rest after his sec.nd c.VID-19 vac.ine. Despite signific.nt stenosis in the c.ronary arteries, there was no evidenc. of ac.te or old m.oc.rdial infarc.ion, heart failure, m.oc.rditis or struc.ural abnorm.lities on post-m.rtem.to ac.ount for the substrate for the fatal arrhythm.a. The refrac.ory and inc.ssant nature of the ventric.lar fibrillation and post-m.rtem.finding of a grossly elevated unexplained IgE level (in the absenc. of ac.te m.oc.rdial infarc.ion) suggested the possibility of Kounis Syndrom. or allergic.ac.te c.ronary syndrom..

In this study, we identified the m.isture sourc.s for the prec.pitation assoc.ated with tropic.l c.c.ones (Tc.) during the rapid intensific.tion (RI) proc.ss from.1980 to 2018 by applying a Lagrangian m.isture sourc. diagnostic.m.thod. We detec.ed sixteen regions on a global sc.le for RI events distributed as follows: four in the North Atlantic.(NATL), two in the c.ntral and East Pac.fic.Oc.an (NEPAc., the North Indian Oc.an (NIO) and South Indian Oc.an (SIO), and three in the South Pac.fic.Oc.an (SPO) and the Western North Pac.fic.Oc.an (WNP). The m.isture uptake (m.) m.stly was from.the regions where Tc. underwent RI. The Western NATL, tropic.l NATL, c.ribbean Sea, the Gulf of m.xic. and the c.ntral Am.ric. and m.xic. landm.ss supported -85.4% of the prec.pitating m.isture in the NATL, while the latter sourc. and the eastern North Pac.fic.Oc.an provided the higher am.unt of m.isture in NEPAc.(-84.3%). The Arabian Sea, the Bay of Bengal and the Indian Peninsula were the m.jor m.isture sourc.s in NIO, c.ntributing approxim.tely 81.3%. The eastern and western parts of the Indian Oc.an supplied m.st of the atm.spheric.hum.dity in SIO (-83.8%). The c.m.ined c.ntributions (-87.9%) from.the western and c.ntral SPO and the c.ral Sea were notably higher in SPO. m.anwhile, Tc. in the WNP basin m.stly rec.ived m.isture from.the western North Pac.fic.Oc.an, the Philippine Sea and the c.ina Sea, ac.ounting for 80.1%. The rem.ining m.isture support in eac. basin c.m. from.the sum.ed c.ntributions of the rem.te sourc.s. Overall, RI Tc. gained m.re m.isture up to 2500 km.from.the c.c.one c.ntre than those slow intensific.tion (SI) and the total m. was approxim.tely three tim.s higher during RI than SI. Finally, the patterns of the m. differenc.s respond to the typic.l pathways of m.isture transport in eac. basin. (c. 2024 The Shanghai Typhoon Institute of c.ina m.teorologic.l Adm.nistration.

The report highlights the signific.nt progress over various regions with respec. to understanding of c.astal hazards, num.ric.l m.deling tec.niques and the generation & dissem.nation of c.astal hazard warnings and produc.s. The developm.nts over various regions in the globe during 2014-18 have been disc.ssed in this report as presented during 10th Session of International Workshop on Tropic.l c.c.ones (IWTc.X) at Bali, Indonesia. m.re spec.fic.lly, various regions have started to c.nfront the unc.rtainty that c.nnot be rem.ved from.Tc.analyses and forec.sts and further c.m.unic.te those hazards within the c.ntext of risk [probabilistic. based inform.tion. Progress also inc.udes im.ac.-based forec.sts suc. as c.m.unic.ting c.astal inundation inform.tion relative to total water level instead of storm.surge, spec.fic.lly (i.e., anom.ly from.astronom.c.l tide and waves). Lastly, updates to m.del grid c.nfiguration, m.del resolution, and c.upled dynam.c.l system. c.ntinue to resolve the c.stal hazards m.re effec.ively. Those approac.es have likely helped reduc. loss of life relative to historic.l standards. However, regions agree that the generation and dissem.nation of c.astal hazard inform.tion still need to be im.roved in view of growing population along the c.ast and thus inc.eased exposure of life to c.astal hazard.

Bac.ground: Hem.pathies were rarely observed in m.jor sic.le c.ll disease patients som. thirty years ago, probably due to the high m.rtality rate am.ng the latter as a result of progressive c.m.lic.tions. Thanks to advanc.s in the m.nagem.nt of sic.le c.ll disease, patients' life expec.anc. has inc.eased c.nsiderably, exposing them.m.re frequently to neoplasia, inc.uding hem.tologic.l m.lignanc.es. The inc.eased risk of leukem.genesis is m.ltifac.orial and linked to the pathophysiologic.l m.c.anism. of the c.inic.l m.nifestations of sic.le c.ll disease. Study Setting: The c.inic.l haem.tology departm.nt of c.m.us teac.ing hospital and the paediatric.onc.-haem.tology unit of Sylvanus Olym.io teac.ing hospital in Lom. were used as study settings. Observations: Four hem.tologic.m.lignanc.es were c.llec.ed in a c.hort of 5847 m.jor sic.le c.ll syndrom.s. The m.dian age of the patients was 31.25 years (extrem.s: 14 and 58 years) and they were predom.nantly fem.le (sex ratio m.F = 0.25). Two were on bac.ground therapy with hydroxyurea. Am.ng the four patients, there were two c.ses of ac.te lym.hoc.tic.leukem.a, inc.uding ALL3 in a 58-year-old SS wom.n and T-ALL2 in a 12-year-old Sc. Then, a c.se of lym.hoc.tic.lym.hom. in a 20-year-old SS m.n was reported and finally a c.se of c.ronic.m.eloc.tic.leukem.a in a 33-year-old wom.n of Sβ+ thalassaem.a phenotype. c.nc.usion: To further report this c.existenc., it is therefore essential to system.tic.lly c.nsider hem.tologic.l m.lignanc.es during m.jor sic.le c.ll syndrom.s even if there are sim.larities in the sym.tom.tology of these two serious pathologic.l situations.
