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. .

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. This comprehen.ive comparison.provides valuable guidan.e for selectin. effective n.merical methods for differen.ial equation. in.en.in.erin..

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).

Aeromagn.tic data over the Mamfe Basin.have been.processed. A region.l magn.tic gridded dataset was obtain.d from the Total Magn.tic In.en.ity (TMI) data grid usin. a 3 × 3 con.olution.(Han.in.) filter to remove region.l tren.s. Major similarities in.magn.tic field orien.ation.an. in.en.ities were observed at iden.ical location. on.both the region.l an. TMI data grids. From the region.l an. TMI gridded datasets, the residual dataset was gen.rated which represen.s the very shallow geological features of the basin. Processin. this residual data grid usin. the Source Parameter Imagin. (SPI) for magn.tic depth suggests that the estimated depths to magn.tic sources in.the basin.ran.e from about 271 m to 3552 m. The highest depths are located in.two main.location. somewhere aroun. the cen.ral portion.of the study area which correspon. to the area with positive magn.tic susceptibilities, as well as the areas exten.in. outwards across the eastern.boun.ary of the study area. Shallow magn.tic depths are promin.n. towards the n. portion.of the basin.an. also correspon. to areas of n.gative magn.tic susceptibilities. The basin.gen.rally exhibits a variation.in.depth of magn.tic sources with high, average an. shallow depths. The presen.e of in.rusive ign.ous rocks was also observed in.this basin. This characteristic is a poin.er to the existen.e of geologic resources of in.erest for exploration.in.the basin.
