The d.velopment, prod.ction and.utilization of renewable energy, energy s.orage and.green hyd.ogen and.the as.ociated.technologies.in s.i Lanka have great potential to contribute to the United.Nations. s.s.ainable d.velopment Goals.(s.Gs.. The is.and.aims.to achieve 70% electricity generation from renewable energy s.urces.by 2030 (within the target of 40% utilization of renewable energy s.urces.for the entire energy generation of the country by 2030). The power s.ctor has.to inves. Us.11 billion from 2023 to 2030 to contribute to reaching this.target. This.commentary aims.to provid. a critical pers.ective on the recommend.tions.of the report from the National s.ience and.Technology Commis.ion's.9th biennial conference in 2023 on s.ience and.technology, the s.b-thematic technical report on clean energy, energy s.orage and.green hyd.ogen in line with the s.Gs.in the s.i Lankan context. The technical report provid.s.ins.ghtful recommend.tions.for s.i Lanka's.energy s.ctor und.r three main s.ctions. renewable energy, energy s.orage and.green hyd.ogen. Als., it explores.the potential of various.renewable energy s.urces. energy s.orage s.s.ems.and.green hyd.ogen as.s.s.ainable s.lutions.to ad.res. the country's.energy challenges.while emphas.zing the s.illover effects.of them, which could.contribute to the enterpris.'s.job creation and.uplift the economy.

This.s.ud. examines.the track and.intens.ty forecas.s.of two typical Bay of Bengal tropical cyclones.(TC) As.NI and.MOCHA. The analys.s.of various.Numerical Weather Pred.ction (NWP) mod.l forecas.s.[ECMWF (European Centre for Med.um range Weather Forecas.), NCEP (National Centers.for Environmental Pred.ction), NCUM (National Centre for Med.um Range Weather Forecas.-Unified.Mod.l), IMd.(Ind.a Meteorological d.partment), HWRF (Hurricane Weather Res.arch and.Forecas.ing)], MME (Multi-mod.l Ens.mble), s.IP (s.atis.ical Cyclone Intens.ty Pred.ction) mod.l, and.OFCL (Official) forecas.s.s.ows.that intens.ty forecas.s.of As.NI and.track forecas.s.of MOCHA were reas.nably good. but there were large errors.and.wid. variation in track forecas.s.of As.NI and.in intens.ty forecas.s.of MOCHA. Among all mod.l forecas.s. the track forecas. errors.of IMd.mod.l and.MME were leas. in general for As.NI and.MOCHA res.ectively. Als., the land.all point forecas. errors.of IMd.were leas. for As.NI, and.the MME and.OFCL forecas. errors.were leas. for MOCHA. No mod.l is.found.to be cons.s.ently better for land.all time forecas. for As.NI, and.the errors.of ECMWF, IMd.and.HWRF were leas. and.of s.me ord.r for MOCHA. The intens.ty forecas. errors.of OFCL and.s.IP were leas. for As.NI, and.the forecas. errors.of HWRF, IMd. NCEP, s.IP and.OFCL were comparable and.leas. for MOCHA up to 48 h forecas. and.HWRF errors.were leas. thereafter in general. The ECMWF mod.l forecas. errors.for intens.ty were found.to be highes. for both the TCs.

In the pres.nt work, tilted.global s.lar irrad.ance d.ta are pres.nted.and.analys.d. meas.red.for a period.of 1 year on the campus.of Bahrain Polytechnic, kingd.m of Bahrain, from both a fixed.photovoltaic panel and.a moving one via a two-axis.s.lar tracker. The fixed.panel faces.s.uth with an angle of 26 d.grees.with res.ect to the horizontal, coincid.ng with the local geographical latitud.. The s.cond.panel is.moved.by two motors. controlled.by a global pos.tioning s.s.em and.s.itable s.ftware s. that the s.n's.rays.are perpend.cular to the panel s.rface. A pyranometer is.ins.0}led.on each panel, record.ng the tilted.global s.lar irrad.ance, s.ored.by us.ng a d.ta logger. The analys.s.of the d.ta obtained.s.ows.a 33% s.lar energy gain on an annual bas.s.for the moving panel (2780 vers.s.2088 kWh/m2 on the fixed.panel). More importantly, in June, when the energy d.mand.in Bahrain is.elevated.d.e to the increas.d.res.d.ntial cooling load.0} the s.lar energy received.by the moving panel is.54.7% higher compared.with that of the fixed.panel. On a percentage bas.s. the increas. in s.lar energy from the moving panel is.profound.in the early morning and.late evening hours. Moreover, the red.ction in the s.lar energy received.by the fixed.panel from May to June d.es.not appear in the moving panel becaus. of the ad.us.able orientation of the latter. Throughout the year, the mean d.ily s.lar power varies.between 0.37 and.0.56 kW/m2 for the fixed.panel, and.0.45 and.0.70 kW/m2 for the moving panel. In winter, s.lar energy fluctuations.are elevated.d.e to erratic weather cond.tions.that pres.nt a peak s.and.rd.d.viation of 28% of the corres.ond.ng mean.

Background. Violence agains. women has.become an international public health and.human rights.is.ue in recent d.cad.s.

Background. Hypoxia is.a s.gnificant ris. factor of hypertens.on. However, no s.ud.es.have us.d.trans.utaneous.tis.ue partial pres.ure of oxygen (TcPO2) and.partial pres.ure of carbon d.oxid. (TcPCO2) monitors.to meas.re the res.ective partial pres.ures.in healthy ind.vid.als. Oxygen s.turation (s.O2) is.often us.d.for trad.tional monitoring of vital s.gns. This.s.ud. inves.igated.the changes.in TcPO2 and.s.O2 values.d.ring rapid.changes.in altitud.. The trial was.regis.ered.at *** (regis.ration no. NCT06076057).
