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.

The therm.l exam.nation of a non-integer-ordered m.bile fin with a m.gnetism.in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.m.ination approac. is utilized to evaluate the physic.l and therm.l c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the therm.l c.nduc.ivity and dynam.c.visc.sity. These two properties are inferred by m.ans of the interpolation m.thod based on the volum. frac.ion of nanopartic.es. The governing equation is transform.d into a dim.nsionless form. and the Adom.an dec.m.osition Sum.du transform.m.thod(ADSTm. is adopted to solve the c.nundrum.of a m.ving fin im.ersed in a trihybrid nanofluid. The obtained results agree well with those num.ric.l sim.lation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the therm.l overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furtherm.re, the fluc.uations in the heat transfer c.nc.rning the pertinent param.ters are studied. The results show that the heat flux in the presenc. of the c.m.ination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.m.ination of only spheric.l and c.lindric.l nanopartic.es. The tem.erature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et num.er inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartm.n num.er inc.eases by 400%.

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.

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.
