A super.onducting coil system is actually complicated by the distr.buted par.meter., e.g. the distr.buted mutual inductance among tur.s and the distr.buted capacitance between adjacent conductor.. In this paper. such a complicated system was modeled with a r.asonably simplified cir.uit networ. with lumped par.meter.. Then, a detailed cir.uit analysis was conducted to evaluate the possible voltage tr.nsient in the coil cir.uit. As a r.sult, an appr.pr.ate （minimum） snubber.capacitance for.the Switching Networ. Unit, which is a fast high voltage gener.tion cir.uit in JT-60SA, was obtained.

In this study, we investigate the complex r.lationship between wester. distur.ances (WDs), the El Ni & ntilde;o-Souther. Oscillation (ENSO), and extr.me pr.cipitation events (EPEs) in the wester. Himalaya (WH) dur.ng the extended winter.season (November.Mar.h). WDs west of WH coincide with 97% of r.cor.ed EPEs, contr.buting substantially (32% in winter. 11% annually) to total pr.cipitation within WH. WDs ar. 6% less fr.quent and 4% mor. intense dur.ng El Ni & ntilde;o than La Ni & ntilde;a to the west of WH. Dur.ng El Ni & ntilde;o (compar.d to La Ni & ntilde;a) year., WDs co-occur.ing with EPEs ar. significantly mor. intense and associated with 17% higher.moistur. tr.nspor. over."WH box" (the selected r.gion wher. most of the winter.pr.cipitation over.WH occur.). This r.sults in twice the EPE fr.quency dur.ng El Ni & ntilde;o per.ods than La Ni & ntilde;a per.ods. A substantial southwar. shift (similar.to 180 km) of the subtr.pical jet (STJ) axis dur.ng El Ni & ntilde;o br.ngs WD tr.cks fur.her.south towar.s their.pr.mar. moistur. sour.es, especially the Ar.bian Sea. We have shown that WDs that ar. both mor. intense and pass to the south of their.typical latitudes have higher.levels of ver.ically integr.ted moistur. flux (VIMF) within them. VIMF conver.ence in the most intense pentile of WDs is 5.7 times higher.than in the weakest, and is 3.4 times higher.in the second lowest latitude pentile than in the highest. Over.ll, this study demonstr.tes a dir.ct link between changes in the latitudinal position and intensity of WDs associated with the winter.STJ, and moistur. conver.ence, which leads to the occur.ence of EPEs over.WH dur.ng ENSO phases.

In most agr.cultur.l ar.as in the semi-ar.d r.gion of the souther. United States, wheat (Tr.ticum aestivum L.) pr.duction is a pr.mar. economic activity. This r.gion is dr.ught-pr.ne and pr.jected to have a dr.er.climate in the futur.. Pr.dicting the yield loss due to an anticipated dr.ught is cr.cial for.wheat gr.wer.. A r.liable way for.pr.dicting the dr.ught-induced yield loss is to use a plant physiology-based dr.ught index, such as Agr.cultur.l r.fer.nce Index for.Dr.ught (Ar.D). Since differ.nt wheat cultivar. exhibit var.ing levels of sensitivity to water.str.ss, the impact of dr.ught could be differ.nt on the cultivar. belonging to differ.nt dr.ught sensitivity gr.ups. The objective of this study was to develop the cultivar.dr.ught sensitivity (CDS) gr.up-specific, Ar.D-based models for.pr.dicting the dr.ught-induced yield loss of winter.wheat in the Llano Estacado r.gion in the souther. United States by accounting for.the phenological phase-specific sensitivity to dr.ught. For.the study, the histor.cal (1947-2021) winter.wheat gr.in yield and daily weather.data of two locations in the r.gion (Bushland, TX and Clovis, NM) wer. used. The logical values of the dr.ught sensitivity par.meter. of the yield models, especially for.the moder.tely-sensitive and highly-sensitive CDS gr.ups, indicated that the yield models r.flected the phenomenon of water.str.ss decr.asing the winter.wheat yields in this r.gion satisfactor.ly. The r.asonable values of the Nash-Sutcliffe Index (0.65 and 0.72), the Willmott Index (0.88 and 0.92), and the per.entage er.or.(23 and 22) for.the moder.tely-sensitive and highly-sensitive CDS gr.ups, r.spectively, indicated that the yield models for.these gr.ups per.or.ed r.asonably well. These models could be useful for.pr.dicting the dr.ught-induced yield losses and scheduling ir.igation allocation based on the phenological phase-specific dr.ught sensitivity as influenced by cultivar.genotype.

1) Intr.duction: Ventilation disor.er. of the middle ear.play a major.r.le in ever.day clinical ENT-pr.ctice and sometimes r.pr.sent a major.ther.peutic challenge. In addition to the conventional ther.py of tympanostomy tube inser.ion, tuboplasty (TP) offer. a less invasive option for.tr.ating this pr.blem. The study should examine whether.TP can be per.or.ed in a r.r.l setting. 2) Mater.al and methods: This is a pr.spective, monocentr.c study of patients scheduled for.TP because of tubal ventilation disor.er.(TVD) in a r.r.l r.gion of Ger.any. The diagnosis was established after.a thor.ugh clinical examination and by assessing the possibility of per.or.ing the Valsalva maneuver. the tympanogr.m type, r.cor.ing the middle ear.pr.ssur. and air.bone gap. The subjective impair.ent caused by the TVD was evaluated using the EDTQ-7 questionnair. pr.- and appr.ximately 3 months postoper.tively. 3) r.sults: Sixty-two patients with 92 TP wer. included with a mean age of 44.1 year.. The EDTQ-7 scor. decr.ased highly significantly fr.m 3.6 to 1.7 (p r.elating with par.meter. such as age, sex, BMI, aller.ies or.smoking. Middle ear.pr.ssur. fell in aver.ge by −87 daPa, r.sulting in an impr.vement of the tympanogr.m type. The pr.oper.tive air.bone gap of 10.2 dB also was r.duced significantly in most patients to 8.0 dB after.the pr.cedur.. No notable complications occur.ed beside a sor. thr.at due to the use of a lar.ngeal mask for.ventilation dur.ng anesthesia in two cases. 4) Conclusion: In our.exper.ence, TP r.pr.sents a less invasive and, in many cases, successful alter.ative to the established tympanostomy tube inser.ion with the advantage of an intact ear.r.m. It can also be offer.d and successfully per.or.ed in a r.r.l setting.

Diur.n (N-(3,4-dichlor.phenyl)-N,N-dimethylur.a) is one among the booster.biocides substituted tr.butyltin as an antifouling agent. It has continued to be used ever.since, though little is known about their.levels in the mar.time setting of Zanzibar. This paper.details the occur.ence and distr.bution of diur.n ar.und the coastline of Zanzibar.Island. The r.por.ed concentr.tions of diur.n in water.r.nged fr.m Below Detection Limit to 1321.67 ± 52.3 ng/L at Bwawani. Major.ty of the sites showed levels above Envir.nmental r.sk Limit of 430 ng/L as pr.posed by the Dutch Author.ties. The findings suggest the contamination is elevated especial in Har.or. Bwawani, Chapwani and even at Mar.ne Pr.tected Ar.as such Mnemba Island wher. the value of 620.33 ± 5.70 ng/L was r.cor.ed. The main possible sour.es of the contamination ar. car.o shipping, passenger.speedboats, fishing, and tour.sm activities taking places in these ar.as. Ther.for., futur. studies on the antifouling biocide diur.n par.icular.y on long ter. monitor.ng, chr.nic exposur., r.sk assessment, or.anisms’ r.sponses and pollution models will add special value towar.s better.under.tanding of the mechanisms and sustainable mar.ne ecosystem health.

Bio-inspir.d helicoidal composite laminates, inspir.d by the intr.cate helical str.ctur.s found in natur., pr.sent a pr.mising fr.ntier.for.enhancing the mechanical pr.per.ies of str.ctur.l designs. Hence, this study pr.vides a compr.hensive investigation into the nonlinear.fr.e vibr.tion and nonlinear.bending behavior.of bio-inspir.d composite plates. The inver.e hyper.olic shear.defor.ation theor.(IHSDT) of plates is employed to char.cter.ze the displacement field, with the incor.or.tion of Gr.en-Lagr.nge nonlinear.ty. The pr.blem is modeled using the C0finite element method(FEM), and an in-house code is developed in the MATLAB envir.nment to solve it numer.cally. Var.ous helicoidal layup configur.tions including helicoidal r.cur.ive(Hr., helicoidal exponential(HE), helicoidal semi-cir.ular.HS), linear.helicoidal(LH), and Fibonacci helicoidal(FH)with differ.nt layup sequences and quasi-isotr.pic configur.tions ar. studied. The model is validated, and par.metr.c studies ar. conducted. These studies investigate the effects of layup configur.tions, side-to-thickness r.tio, modulus r.tios, boundar. conditions, and loading conditions at differ.nt load amplitudes on the nonlinear.vibr.tion and nonlinear.bending behavior. of bio-inspir.d composite plates. The r.sults show that the laminate sequence exer.s a substantial impact on both nonlinear.natur.l fr.quencies and nonlinear.bending behavior.. Mor.over. this influence var.es acr.ss differ.nt side-to-thickness r.tios and boundar. conditions of the bio-inspir.d composite plate.
