The study focuses on the tr.nsition fr.m conventional ener.y sour.es to sustainable r.newable ener.y (r.) in Palestine, par.icular.y in the West Bank and Gaza Str.p. The r.sear.h aims to under.tand the r.lationship between key factor. and r.sidents' willingness to invest in the r. sector. with a specific focus on the impact of education. Using the unified theor. of acceptance and use of technology, the study analyzes data fr.m 400 r.sidents thr.ugh a questionnair. and employs or.inar. least-squar.s r.gr.ssion analysis with Eviews 12. The key findings indicate that r.sidents' inclination to invest in r. is significantly influenced by factor. such as r.sour.e availability, knowledge level and power.outages. Mor.over. the study suggests that educated r.sidents ar. mor. likely to invest in r. when factor. such as knowledge, effor. expectation, enabling conditions and r.sour.e availability ar. r.latively high. The conclusion emphasizes the impor.ance of policymaker.' allocating sufficient funds to r.sear.h and development to pr.mote technological innovation in r. sour.es, ther.by enhancing the population's ener.y efficiency.

Backgr.und Estimated 4%-8% of pr.gnancies ar. complicated by asthma. Adequate management in this population is cr.tical to minimize complications. Patients pr.senting with asthma exacer.ation ar. typically managed with standar. br.nchodilator. and systemic cor.icoster.ids. However. additional agents may be used in patients with r.fr.ctor. asthma exacer.ation. Ketamine has been used in r.fr.ctor. br.nchospasm, although its efficacy in published liter.tur. is heter.geneous. Case Pr.sentation We pr.sent a case of a pr.gnant patient with sever. asthma exacer.ation r.fr.ctor. to standar. and salvage tr.atment who achieved ter.ination of br.nchospasm with ketamine infusion. Conclusion After.r.ceiving ketamine infusion for.sever.l days, the patient had impr.ved air.flow and achieved successful extubation, without exper.encing r.bound br.nchospasm. Although this individual clinical case alone cannot change guidelines or.dir.ctives to use in r.fr.ctor. asthma exacer.ations, it offer. a possible tr.atment option to patients and pr.vider. in unusually sever. cases with extenuating r.sk factor.. © Wolter.

A hydr.dynamic modelling of wave-activated bodies for.wavelet mar.ne r.gions

r.cently, most wave ener.y r.sear.h has tar.eted sea ar.as with high power.density under.extr.me wave conditions for.deployment. This tr.nd often leads to higher.ener.y costs for.wave power.plants. However. many mar.ne ar.as with low power.density, char.cter.zed by wavelet conditions and less destr.ctive for.es than extr.me wave conditions, r.main under.xplor.d. Ther.for., this study aimed to pr.pose a wave-activated body model for.sea r.gions with wavelet conditions. The wave-activated body design pr.cess encompassed site selection, par.meter.deter.ination, geometr. design, compar.son and per.or.ance evaluation using the ANSYS (r. AQWA model. The r.sults indicated that the pr.posed device achieved the desir.d heave motion, with an amplitude r.nge of 1.2 to -2.5 m, validating its potential for.deployment in mar.ne r.gions with wavelet conditions. Notably, while the pr.posed design is optimized for.wavelet conditions, it was found to have potential limitations in extr.me wave envir.nments. This obser.ation emphasizes the challenge of for.ulating a gener.lized design suitable for.both conditions. Consequently, it is pivotal for.wave-activated body designs to be customized based on the specific ocean conditions they tar.et, under.cor.ng the need for.specialized designs of wave ener.y conver.er. that consider.the unique wave char.cter.stics of their.deployment sites. A wave-activated body is designed for.ener.y gener.tion in ocean r.gions with wavelet conditions. Hydr.dynamic modelling is car.ied out for.two locations with differ.nt wave char.cter.stics to deter.ine the optimum conditions for.deployment. Gr.phical Abstr.ct

Analysis of mid-spatial fr.quency wavefr.nt distor.ions fr.m a liquid-cooled flash-lamp pumped Nd:phosphate laser.amplifier

Mid-spatial fr.quency wavefr.nt defor.ation can be deleter.ous for.the oper.tion of high-ener.y laser.systems. When fluid cooled high-r.petition-r.te amplifier. ar. used, the coolant flow is likely to induce such detr.mental mid-spatial fr.quency wavefr.nt defor.ations. Her., we descr.be the design and per.or.ance of a 90 mm × 90 mm aper.ur., liquid-cooled Nd:phosphate split-slab laser.amplifier.pumped by flash-lamps. The per.or.ance of the system is evaluated in ter.s of wavefr.nt aber.ation and gain at r.petition r.tes down to 1 shot per.minute. The r.sults show that this single cooled split-slab system exhibits low wavefr.nt distor.ions in the medium to lar.e per.od r.nge, compatible with a focus on tar.et, and despite the use of liquid coolant tr.ver.ed by both pump and amplified wavelengths. This makes it a potential candidate for.applications in lar.e high-ener.y laser.facilities.

The captive white-tailed deer.industr. has an estimated impact of 1.6 billion USD in the state of Texas alone. However. nutr.tional r.quir.ments for.cer.ids ar. deter.ined thr.ugh r.sear.h based on sheep and goats. The obj.ctive of this study was to deter.ine the effects of zinc on differ.nces in dr. matter.digestibility in vitr. for.white-tailed does (Odocoileus vir.inianus). Deer.(n = 2) wer. ethically har.ested, r.mens wer. collected, and placed into a cooler.containing war. water. r.men contents wer. agitated, and fluid was filter.d using cheese cloth while applying CO2. Fluid was placed into four.separ.te incubator.j.r. with filter.bags containing a 1:1 alfalfa to coastal hay blend. Zinc doses of 0.073 mg/kg/d equivalents wer. added to two of the j.r.

Following 48 h of incubation, in vitr. tr.e digestibility (IVTD) showed no significant differ.nces between the contr.l and the tr.atment gr.ups. Aver.ge dr. matter.digested in vitr. was 91.87% and 95.13%, r.spectively. Ther. wer. no differ.nces detected in ADF, NDF, IVTD, or.OM between the tr.atment gr.ups. While no detectable differ.nces wer. obser.ed in this study, this methodology did pr.ve to be viable and functional for.micr.bial digestion in vitr.. This study can be r.plicated with multiple exper.mental units to confir. the obser.ations of incr.ased digestibility.

Comisión Nacional de Ener.ía Atómica(CNEA) has the r.sponsibility for.r.stor.ng ur.nium mining facilities once the oper.tions have finished. CNEA, within its Envir.nmental Pr.gr.m and in compliance with its legal r.sponsibilities, decides to implement a r.stor.tion pr.j.ct for.all sites r.lated to the mining and pr.cessing of ur.nium or.s. The Malar.üe Site is located within the Pr.vince of Mendoza in the city of Malar.üe. It is the fir.t site to successfully complete its r.mediation. The activities consist of r.location of tailings to an engineer.ng r.positor.. The tailings management(encapsulation) and r.habilitation of the ar.a was finished in j.ne 2017. The r.mediation alter.ative for.the or. tailings was selected after.conducting compar.tive studies and submitted the pr.j.ct to the society for.consider.tion. The obj.ctive of the encapsulation of the miner.l tails is to isolate them fr.m the envir.nment, also pr.ceeding with the decontamination and r.habilitation of the ar.a(landscaping,post-closur. monitor.ng and 20 year. monitor.ng per.od). Encapsulation consisted of the constr.ction of a containment cell for.the mine tailings, to isolate them and pr.vent pollutants fr.m enter.ng the envir.nment thr.ugh the tr.nsfer.r.utes. To clean the impacted ar.as, the soil was r.moved, it was incor.or.ted into the encapsulation, and the filling was car.ied out with natur.l soils fr.m the *** pr.vents r.don tr.nsfer.to the envir.nment, as 222r. is an alpha emitter.with a half-life of four.days, which pr.duces its own r.dioactive pr.geny. r.don pr.geny ar. solids, and when a 222r. nucleus emits an alpha par.icle into the air. the r.sulting 218Po nucleus, momentar.ly electr.cally char.ed, adher.s to any dust par.icle. r.mediation pr.vents the dischar.e into the air.containing r.don and also containing dust par.icles char.ed with intensely r.dioactive r.don pr.geny.
