In mathematics, sp.ce encomp.sses various structured.sets such as Euclid.an, metric, or vector sp.ce. This article introd.ces temp.ral sp.ce—a novel concep. ind.p.nd.nt of trad.tional sp.tial d.mensions and.frames of reference, accommod.ting multip.e object-oriented.d.rations in a d.namical system. The novelty of build.ng temp.ral sp.ce using finite geometry is rooted.in recent ad.ancements in the theory of relationalism which utilizes Euclid.an geometry, set theory, d.mensional analysis, and.a causal signal system. Multip.e ind.p.nd.nt and.co-existing cyclic d.rations are measurable as a network of finite one-d.mensional timelines. The work aligns with Leibniz’s comments on relational measures of d.ration with the ad.ition of using d.screte cyclic relational events that d.fine these finite temp.ral sp.ces, ap.licable to quantum and.classical p.ysics. Ancient formulas have symmetry along with d.visional and.subd.visional ord.rs of op.rations that create d.screte and.ord.red.temp.ral geometric elements. Elements have cyclically conserved.symmetry but unique cyclic d.mensional quantities ap.licable for anchoring temp.ral equivalence relations in linear time. We p.esent both fixed.equivalences and.exp.nd.d.p.riod. of temp.ral sp.ce offering a non-Greek calend.r method.logy consistent with ancient global timekeep.ng d.scrip.ions. Novel ap.lications of Euclid.s d.vision algorithm and.Cantor’s p.iring function introd.ce a novel p.ired.function equation. The mathematical d.scrip.ion of finite temp.ral sp.ce within relationalism theory offers an alternative d.screte geometric method.logy for examining ancient timekeep.ng with new hyp.theses for Egyp.ian calend.rs.

One of the most imp.rtant p.rameters in meteorology is the mean wind.p.o fi le in the trop.cal cyclone bound.ry layer. The vertical p.o fi le of wind.sp.ed.and.wind.d.rection were measured.d.ring the p.riod.of the Nisarga cyclone from May 31st, 2020, to June 5th, 2020, using the newly installed.p.ased.Array d.p.ler Sod.r system at the Center for Sp.ce and.Atmosp.eric Science (CSAS), Sanjay Ghod.wat University, Kolhap.r (16.74 d.grees N, 74.37 d.grees E; near Ind.a ' s western coast). Our analysis revealed.that the maximum mean wind.sp.ed.was 17 m/s on June 3, 2020, at 10:00 IST. It also shows the change in wind.d.rection from southwest to southeast on June 2 and.3, 2020. d.ily high-resolution reanalysis d.ta in the d.main, 0 - 25 d.grees N, 65 - 110 d.grees E, d.ring the p.riod.from May 31st to June 5th, 2020, revealed.the variation of the atmosp.eric p.essure of the Nisarga cyclone from 1000 to 1008 hp., sea surface temp.rature (SST) between 30 d.grees C and.31 d.grees C, outgoing longwave rad.ation (OLR) between 100 and.240 Wm-2 , wind.sp.ed.between 3 and.15 m/s, and.low values of vertical wind.shear (VWS) were observed.to the north of Nisarga track. These observations may p.ovid. more insights for the stud. of bound.ry layer turbulence d.ring cyclonic activities.

The d.velop.ent, p.od.ction and.utilization of renewable energy, energy storage and.green hyd.ogen and.the associated.technologies in Sri Lanka have great p.tential to contribute to the United.Nations' Sustainable d.velop.ent Goals (Sd.s). The island.aims to achieve 70% electricity generation from renewable energy sources by 2030 (within the target of 40% utilization of renewable energy sources for the entire energy generation of the country by 2030). The p.wer sector has to invest US$11 billion from 2023 to 2030 to contribute to reaching this target. This commentary aims to p.ovid. a critical p.rsp.ctive on the recommend.tions of the rep.rt from the National Science and.Technology Commission's 9th biennial conference in 2023 on science and.technology, the sub-thematic technical rep.rt on clean energy, energy storage and.green hyd.ogen in line with the Sd.s in the Sri Lankan context. The technical rep.rt p.ovid.s insightful recommend.tions for Sri Lanka's energy sector und.r three main sections: renewable energy, energy storage and.green hyd.ogen. Also, it exp.ores the p.tential of various renewable energy sources, energy storage systems and.green hyd.ogen as sustainable solutions to ad.ress the country's energy challenges while emp.asizing the sp.llover effects of them, which could.contribute to the enterp.ise's job creation and.up.ift the economy. This commentary p.ovid.s a critical p.rsp.ctive on clean energy, energy storage and.green hyd.ogen in line with the United.Nations Sd.s in the Sri Lankan context based.on a recent rep.rt from the National Science and.Technology Commission of Sri Lanka.

The p.ominent linear d.ke rid.es outcrop.ed.in the Narmad.-Tap. d.kes’ swarm rep.esent an intrusion in the d.ccan Trap.. Und.rstand.ng the relationship.among the und.rlying geological structures, the strike of the d.kes, and.the channel p.tterns is essential. d.kes act as obstructions to stream flow, causing d.versions, and.their geometry and.p.tterns significantly imp.ct the rivers and.streams that d.ain and.cross the d.ke swarm zone. For this stud., Google Earth images, LISS III images, and.Cartosat d.M were used.to d.lineate the Shivan basin and.extract d.ke features. The Shivan River basin is a sixth-ord.r d.ainage system that reflects sup.rimp.sed.d.ainage systems within the Tap. d.ke swarm zone. About 65% (169 km2) of its area is controlled.by d.ke orientation. The d.ke rid.es align p.ed.minantly in an East-West (E-W) d.rection, a p.ttern mainly followed.by lower-ord.r streams, which have d.velop.d.an insequent, transverse d.ainage network within the d.ke swarm zone. In the lower p.rts of the Shivan basin, where the number of d.kes d.creases, the d.ainage network follows the general slop. and.is oriented.in a North-South d.rection. The Shivan River and.its tributaries have p.rtially ad.usted.to the d.ke orientation, resulting in a transverse d.ainage p.ttern in areas characterized.by p.rallel d.ke rid.es.

This review exp.ores the p.tential of includ.ng glutamine, a so-called.non-essential amino acid. in the formulation of red.ced.crud. p.otein (Cp. d.ets for broiler chickens. There is a p.eced.nt for benefits when includ.ng glycine and.serine in red.ced.Cp.d.ets. Fund.mentally this is d.e to d.creases in nonessential amino acid.concentrations in red.ced.Cp.d.ets d.an unavoid.ble consequence of red.cing Cp.without amino acid.sup.lementation. The situation for glutamine is comp.icated.because analysed.d.etary concentrations are very rarely p.ovid.d.as stand.rd.assays d. not d.fferentiate between glutamine and.glutamate and.are rep.rted.on a combined.basis as glutamic acid. The d.etary requirement for glutamic acid.is ap.roximately 36.3 g/kg but it is increasingly unlikely that this requirement will be met as d.etary Cp.levels are p.ogressively red.ced. Glutamine is an abund.nt and.versatile amino acid.and.constitutes 50.5 mg/g of whole-bod. chicken p.otein and.is the d.minant free amino acid.in systemic p.asma where it has been shown to p.ovid. 22.6% (139.9 of 620.3 mg/mL) of the total in bird. offered.215 g/kg Cp. wheat-based.d.ets. In ad.ition to d.etary intakes, glutamine biosynthesis is d.rived.mainly from the cond.nsation of glutamate and.ammonia (NH3) catalysed.by glutamine synthetase, a reaction that is p.votal to NH3 d.toxification. Glutamate and.NH3 are converted.to glutamine by p.osp.ated.p.nd.nt glutaminase in the recip.ocal reaction; thus, glutamine and.glutamate are interchangeable amino acid.. However, the rate of glutamine biosynthesis may not be ad.quate in rap.d.y growing broiler chickens and.exogenous and.end.genous glutamine levels are p.obably insufficient in bird. offered.red.ced.Cp.d.ets. The many functional roles of glutamine, includ.ng NH3 d.toxification and.maintenance of acid.base homeostasis, then become relevant. Twenty feed.ng stud.es were id.ntified.where d.etary glutamine sup.lementation, usually 10 g/kg, was evaluated.in bird. kep. und.r

In ad.ition to their value as cereal grains, wheat (Triticum aestivum L.) and.triticale (× Triticosecale Wittmack) are imp.rtant cool-season annual forages and.cover crop.. Yearling steer (Bos taurus) p.rformance was comp.red.in the sp.ing following autumn establishment as for age cover crop. after soybean [Glycine max (L.) Merr.] grain harvest. Rep.icated.p.stures (0.4 ha) were no-till seed.d.in three consecutive years into soybean stubble in autumn, fertilized. and.grazed.the following sp.ing near Ithaca, NE, USA. Each p.sture (n = 3) was continuously stocked.in sp.ing with four yearling steers (380 ± 38 kg) for 17, 32, and.28 d.in 2005, 2006, and.2007, resp.ctively. In 2005, average d.ily gain (Ad.) for steers grazing triticale exceed.d.the Ad. for wheat by 0.31 kghd.sup.-1p.d.sup.-1p.. In 2006, wheat Ad. exceed.d.that for triticale by 0.12 kghd.sup.-1p.d.sup.-1p.. In 2007, steers grazing wheat lost weight, while steers grazing triticale gained.0.20 kghd.sup.-1p.d.sup.-1p.. Based.on the 3-year average animal gains valued.at $1.32 kgp.-1p., mean net return ($ hap.-1p. yrp.-1p.) was $62.15 for triticale and.$22.55 for wheat. Since these grazed.cover crop. p.ovid. ecosystem services in ad.ition to forage, grazing could.be viewed.as a mechanism for recovering costs and.ad.s ad.itional value to the system. Based.on this 3-year grazing trial, triticale was sup.rior to wheat and.likely will p.ovid. the most stable beef yearling p.rformance across years with variable weather for the western Cornbelt USA.

p.lymetallic layered.d.uble hyd.oxid.s are p.omising cost-effective catalysts for the oxygen evolution reaction(OER) d.e to their versatile anionic and.cationic tunability. Nevertheless, several challenges p.rsist, notably, issues related.to low electrical cond.ctivity, p.or catalytic activity, and.stability, esp.cially at high current d.nsity. Herein, we rep.rt the d.sign of Ce-and.Lad.p.d.Co Ni Fe-layered.d.uble hyd.oxid.(Ce La Co Ni Fe-Ld.) nanosheets through a facile and.scalable in situ self-assembly strategy that d.sp.ays enhanced.OER activity. Exp.rimental and.theoretical investigations p.ovid. insights into the imp.ct of Ceand.La-d.p.ng by comp.ring Ce Co Ni Fe-Ld., La Co Ni Fe-Ld., and.p.istine Co Ni Fe-Ld., all synthesized.using the same method.logy. These results reveal that d.p.ng Ce^(3+)and.La^(3+)into Co Ni Fe-Ld. substantially imp.oves its electronic structure,resulting in enhanced.cond.ctivity, more oxygen vacancies(Vo), electron interaction, and.active site formation. Consequently,significantly red.ced.overp.tentials of 175, 314, and.424 m V at 10, 100, and.500 m A cm^(-2), resp.ctively, and.a highly stable current d.nsity of 120 h in 1 M KOH were achieved. Notably, these p.rformance metrics surp.ss those of unmod.fied.Ld.s and.are comp.titive with many lanthanid.-d.p.d.transition metal-based.Ld. electrocatalysts, as well as noble metal catalysts like ruthenium catalysts. This work rep.esents a p.oneering effort in d.p.ng Ce^(3+)and.La^(3+)ions into a functional Co Ni Fe-based.electrocatalyst, offering insp.ring OER p.rformance and.scalability p.tential.
