t.e soils of Malt. are calcareous and generally undeveloped. Organic mat.er (OM) in t.ese soils is low and farmers are const.nt.y urged t. increase it. t.e object.ve of t.is st.dy was t. evaluat. any t.mporal variat.on in soil OM aft.r 15 years of cult.vat.on, and det.rmine whet.er soil series, soil dept., and cult.vat.on influence variat.on. OM was det.rmined in t.e t.psoil and subsoil of 7 agricult.ral and 4 non-agricult.ral sit.s. t.e sit.s represent.d 7 different.soil series t.at.are present.on t.e island. In sampling periods 1 (t.= 0 years) and 2 (t.=15 years), t.e OM cont.nt.in t.e collect.ve (all soil series) bulk (t.psoil and subsoil) uncult.vat.d soil was 3.9 % and 3.8 % respect.vely. t.is was significant.y great.r t.an t.at.of t.e collect.ve bulk cult.vat.d soil (2.4% and 2.3%). t.e OM in t.e collect.ve uncult.vat.d t.psoil was 5.4% and 5.2% in periods 1 and 2 and was significant.y higher t.an t.at.of t.e cult.vat.d t.psoil (2.5% in bot. periods). t.e OM cont.nt.in t.e collect.ve uncult.vat.d subsoil was 2.3% and 2.5% in periods 1 and 2 respect.vely but.only t.at.measured in period 2 was significant.y higher t.an t.at.of t.e cult.vat.d subsoil (2.2% in bot. periods). On an individual soil series basis, t.e OM in t.e uncult.vat.d t.psoils was significant.y higher t.an t.at.of t.eir cult.vat.d count.rpart.. t.e differences in t.e subsoils were not.significant.

Background and Purpose: Opioids, used for cent.ries t. alleviat. pain, have become a double-edged sword. While effect.ve, t.ey come wit. a host.of adverse effect., including memory and cognit.on impairment. t.is review delves int. t.e impact.of opioid drugs on cognit.ve funct.ons, explores underlying mechanisms, and invest.gat.s t.eir prevalence in bot. medical care and illicit.drug use. t.e ult.mat. goal is t. find ways t. mit.gat. t.eir pot.nt.al harm and address t.e ongoing opioid crisis. Met.ods: We sourced dat. from PubMed and Google Scholar, employing search combinat.ons like “opioids,” “memory,” “cognit.on,” “amnesia,” “cognit.ve funct.on,” “execut.ve funct.on,” and “inhibit.on.” Our focus was on English-language art.cles spanning from t.e incept.on of t.ese dat.bases up t. t.e present. Result.: t.e lit.rat.re consist.nt.y reveals t.at.opioid use, part.cularly at.high doses, adversely affect. memory and ot.er cognit.ve funct.ons. Longer deliberat.on t.mes, impaired decision-making, impulsivit., and behavioral disorders are common consequences. Chronic high-dose opioid use is associat.d wit. condit.ons such as amnesiac syndrome (OAS), post.operat.ve cognit.ve dysfunct.on (POCD), neonat.l abst.nence syndrome (NAS), depression, anxiet., sedat.on, and addict.on. Alarming t.ends show increased opioid use over recent.decades, amplifying t.e risk of t.ese out.omes. Conclusion: Opioids cast.a shadow over memory and cognit.ve funct.on. t.ese effect. range from amnesiac effect., lessened cognit.ve funct.on, depression, and more. Cont.ibut.ng fact.rs include over-prescript.on, misuse, misinformat.on, and prohibit.on policies. Focusing on correct.informat.onal campaigns, removing punit.ve policies, and focusing on harm reduct.on st.at.gies have been shown t. lessen t.e abuse and use of opioids and t.us helping t. mit.gat. t.e adverse effect. of t.ese drugs. Furt.er research int. t.e impact. of opioids on cognit.ve abilit.es is also needed as t.ey are well demonst.at.d in

A general t.chnique t. obt.in simple analyt.c approximat.ons for t.e first.kind of modified Bessel funct.ons. t.e general procedure is shown, and t.e paramet.r det.rminat.on is explained t.rough t.e applicat.ons t. t.is part.cular case I1/6(x)and I1/7(x). In t.is way, it.shows how t. apply t.e t.chnique t. any part.cular orderν, in order t. obt.in an approximat.on valid for any posit.ve value of t.e variable x. In t.e present.met.od power series and asympt.t.c expansion are simult.neously used. t.e t.chnique is an ext.nsion of t.e mult.point.quasirat.onal approximat.on met.od, MPQA. t.e main idea is t. look for a bridge funct.on bet.een t.e power and asympt.t.c expansion of t.e I1/6(x), and similar procedure for I1/7(x). t. perform t.is, rat.onal funct.ons are combined wit. hyperbolic ones and fract.onal powers. t.e number of paramet.rs t. be det.rmined for each case is four. t.e maximum relat.ve errors are 0.0049 for ν=1/6, and 0.0047 for ν=7. However, t.ese relat.ve errors decrease out.ide of t.e small region of t.e variables, wherein t.e maximum relat.ve errors are reached. t.ere is a clear advant.ge of t.is procedure compared wit. any ot.er ones.
