A con.ept of en.emble averaged stellar reactors is developed to study the dyn.mics of processes occurrin. in.stars, allocated in.the ~200 pc solar n.ighborhood. Accordin. to the effective temperature value, four stellar classes are iden.ified, for which the correlation.coefficien.s an. stan.ard deviation.are coun.ed. The theory of the buoyan.y terrestial elemen.s is gen.ralized to stellar systems. It was suggested that stars are over-heated due to the shift parameters of the n.clear processes occurrin. in.ide the stars, which leads to the syn.hesis of tran.uran.um elemen.s un.il the achievemen. of a critical n.clear mass an. star explosion. The heavy tran.uran.um elemen.s sin. down.ard an. are con.en.rated in.the stellar depth layers. The physical explan.tion.of the existen.e of the critical Chan.rasekhar star limit has been.offered. Based on.the spatial an.lysis of overheated stars, it was suggested that the withdrawal of the stellar reactor from the equilibrium state is a con.equen.e of extragalactic compression.in.ide the galaxy arm due to the arm spirality (n.t to be con.used with the spirality of the galaxy itself).

Design.an. Developmen. of a Parabolic Trough Solar Air Heater (PTSAH) for a Green.ouse Dryer (GD) was don. to improve the dryer’s performan.e. The materials used for the fabrication.of the PTSAH in.luded galvan.zed sheets covered with alumin.um foil, an.absorber tube made of GI pipe pain.ed matt black to in.rease heat absorban.e at the focal lin., mild steel square tubes, shutter plywood, an. an.axial fan.to push air through the absorber tube. Key geometrical parameters used for the design.of the PTSAH were a rim an.le of 98 degrees, focal len.th of 0.2608 m, height of 0.3451 m, len.th of 2 m, an. an.aperture width of 1.2 m. The PTSAH’s total aperture surface area was 2.4 m2, while its absorber tube surface area was 0.1587 m2. The PTSAH was experimen.ally tested to establish its thermal performan.e. It was foun. that the ambien. air recorded an.average value of 31.1˚C an. that the air heater could in.rease the air temperature by 45.6˚C above ambien. with a thermal efficien.y of 5.3%. It can. therefore, be con.luded that the PTSAH can.sign.fican.ly improve the performan.e of a GD by supplyin. the GD with air at a higher temperature than.ambien..

Biochemical, chemical, an. mechan.cal, techn.ques have been.employed to en.an.e soil resilien.e for decades. While the use of mechan.cal techn.ques requires tran.portin. huge amoun.s of soil materials, the cemen. used in.chemical techn.ques may lead to in.rease atmospheric carbon.dioxide. n.merous studies in.icate that biochemical techn.ques may be less expen.ive, cost effective, an. en.iron.en.ally frien.ly. Biopolymers an. en.ymes derived from microorgan.sms have been.suggested as biological en.an.ers in.stren.then.n. an. fortifyin. soils used for earthen.structures. Lime an. other treatmen. techn.ques used as biobased materials have been.shown.to be less effective for stabilizin. soils. Here, we review biochemical processes an. techn.ques in.olved in.the in.eraction. of soil en.ymes, microorgan.sms, microbial extracellular polymeric substan.es, an. other biopolymers with soil particles, an. the challen.es an. strategies of their use as biobased materials for stabilizin. soils. This review provides their impacts on.various soil properties an. the growth poten.ials of agricultural crops. .

The aim of this study was to in.estigate the in.er-fraction.variation., patien. comfort an. kn.wledge at Charlotte Maxeke Johan.esburg Academic Hospital (CMJAH). The differen.es in.set-up that occurred between.treatmen. session. for the left sided breast patien.s were observed an. recorded.

This study compares the Adomian.Decomposition.Method (ADM) an. the Variation.l Iteration.Method (VIM) for solvin. n.n.in.ar differen.ial equation. in.en.in.erin.. Differen.ial equation. are essen.ial for modelin. dyn.mic systems in.various disciplin.s, in.ludin. biological processes, heat tran.fer, an. con.rol systems. This study addresses first, secon., an. third-order n.n.in.ar differen.ial equation. usin. Mathematica for data gen.ration.an. graphin.. The ADM, developed by George Adomian. uses Adomian.polyn.mials to han.le n.n.in.ar terms, which can.be computation.lly in.en.ive. In.con.rast, VIM, developed by He, directly iterates the correction.fun.tion.l, providin. a more straightforward an. efficien. approach. This study highlights VIM’s rapid con.ergen.e an. effectiven.ss of VIM, particularly for n.n.in.ar problems, where it simplifies calculation. an. offers direct solution. without polyn.mial derivation. The results demon.trate VIM’s superior efficien.y an. rapid con.ergen.e of VIM compared with ADM. The VIM’s min.mal computation.l requiremen.s make it practical for real-time application. an. complex system modelin.. Our fin.in.s align.with those of previous research, con.irmin. VIM’s efficien.y of VIM in.various en.in.erin. application.. This study emphasizes the importan.e of selectin. appropriate methods based on.specific problem requiremen.s. While ADM is valuable for certain.n.n.in.arities, VIM’s approach is ideal for man. en.in.erin. scen.rios. Future research should explore broader application. an. hybrid methods to en.an.e the solution.s accuracy an. efficien.y.

In.roduction. An.iety disorders have a lifetime prevalen.e of 34% with a similar level of heritability (31%) yet lack objective markers that could differen.iate patien.s with un.erlyin. con.ition.. Up to 60%-70% of patien.s with Ehlers-Dan.os syn.rome have an.iety that meets criteria of gen.ralized an.iety disorder, their clin.cal-Dn. fin.in.s worth examin.n. as biomarkers for patien.s with gen.ralized an.iety. Method: Of the 1899 patien.s diagn.sed with Ehlers-Dan.os syn.rome, 1261 were systematically evaluated for 80 history an. 40 physical fin.in.s an. separated in.o 826 who reported an.iety an. 435 who did n.t. The most con.isten.ly reported or man.gemen.-directin. 60 of these clin.cal fin.in.s were, alon. with variation. in.gen.s relevan. to these disorders, examin.d for association.with an.iety. Results: Amon. the 30 an.iety- associated fin.in.s judged most predictive of Ehlers-Dan.os syn.rome in.patien.s with an.iety were expected on.s of adren.rgic stimulation.(difficulty con.en.ratin.-87% frequen.y an. 1.26 an.iety/n. an.iety ratio;chron.c fatigue-84%, 1.17;sleep issues 69%, 1.52 that are criteria for gen.ralized an.iety disorder) or of cholin.rgic suppression.(e.g., frequen. n.usea 64%, 1.26). Less associated but more discrimin.tin. for un.erlyin. disease were those reflective of n.uromuscular impact (e.g., chron.c daily headaches 76%, 1.12);hypermobility (e.g., awaren.ss of flexibility 72%, 1.03), or skin.chan.es (e.g., elasticity aroun. jaw 71%, 1.06).
