Sta.ic fra.ture toughness cha.a.teristics a.e tra.itiona.ly determined in tests of sta.da.d notched specimens using a.P-V curve, where P is the loa. a.d V is the notch-opening displa.ement. This curve ha. a.cha.a.teristic point Q. a. the loa. PQ corresponding to this point, the cra.k sta.ts to propa.a.e. For this loa., the fra.ture toughness cha.a.teristics a.e then ca.cula.ed. In brittle (ela.tic) fra.ture, the P-V curve a. the onset of cra.k propa.a.ion ha. a. extremum (or a.loca. extremum), from whose ordina.e PQ is determined with sufficient a.cura.y. In ductile a.d ela.tic-ductile fra.ture, P-V curves a.e monotonica.ly increa.ing, a.d PQ is ca.cula.ed using the 5% seca.t offset method without ta.ing into a.count the cha.a.teristics of the ma.eria., so tha. the PQ is determined ina.cura.ely. To improve the a.cura.y of PQ determina.ion, we propose a.thermogra.hic method for determining the fra.ture toughness of meta.s. This method involves plotting the loa. P a.a.nst the tempera.ure cha.ge &Delta.Т over a.rela.ively short period of time a. the notch tip. This plot is then tra.sformed to a.P-ΔS curve, where ΔS is the specific entropy increment a. the notch tip, which is ca.cula.ed through &Delta.Т. This thermodyna.ic dia.ra. ha. a.cha.a.teristic step a. the beginning of cra.k propa.a.ion, a.d from the ordina.e of this step, PQ ca. be determined much more a.cura.ely. Furthermore, in the thermogra.hic method, the prepa.a.ion of test specimens ca. be simplified by repla.ing the process of growing a.fa.igue cra.k a. the tip of a.notch by ma.ing a.sha.p cut, which provides significa.t time sa.ings. Sta.istica. processing a.d compa.ison of test results of steel 20 specimens using the conventiona. a.d thermogra.hic methods ha.e shown the a.va.ta.es of the thermogra.hic method in a.cura.y a.d complexity.

The brea.down of the Heisenberg Uncerta.nty Principle occurs when energies a.proa.h the Pla.ck sca.e, a.d the corresponding Schwa.zschild ra.ius becomes simila. to the Compton wa.elength. Both of these qua.tities a.e a.proxima.ely equa. to the Pla.ck length. In this context, we ha.e introduced a.model tha. utilizes a.combina.ion of Schwa.zschild’s ra.ius a.d Compton length to qua.tify the gra.ita.iona. length of a. object. This model ha. provided a.novel perspective in genera.izing the uncerta.nty principle. Furthermore, it ha. elucida.ed the significa.ce of the deforming linea. pa.a.eter β a.d its ra.ge of va.ia.ion from unity to its ma.imum va.ue.

Ba.kground: Self-ca.e ta.ks or a.tivities of da.ly living (a.L)’s performa.ce a.e often disrupted a.ter a. older a.ult susta.ns a. injury or illness, which ca. be a.determining fa.tor for discha.ge pla.ement a.ter hospita.iza.ion, or it ca. determine the level of a.sista.ce required a.ter discha.ge from a.skilled nursing fa.ility (SNF). We believe tha. comprehensive reha.ilita.ion ca. improve a.pa.ient’s overa.l functioning during their short term sta. in SNFs. The purpose of this study is to determine if a. individua.’s level of independence improved a.ter a.mission to a.skilled nursing fa.ility a.d procurement of reha.ilita.ion services. Methods: This study retrospectively reviewed 4612 nursing home pa.ients in Ca.ifornia.who underwent reha.ilita.ive services a. skilled nursing fa.ilities to determine how the pa.ients responded to their environments, thera.y interventions, a.d a.y other a.ditiona. supportive mea.ures. The records of pa.ients who were a.mitted for short-term reha.ilita.ion were reviewed in a.blinded fa.hion, looking specifica.ly a. Section GG of the Minimum Da.a.Set (MDS). Self-Ca.e Section GG scores recorded by reha.ilita.ive sta.f provide objective da.a.a.d mea.ure pa.ients’ levels of a.sista.ce tha. were required. Ea.h a.tivity is scored from 1, being completely dependent, to 6, being entirely independent, with va.ying levels of a.sista.ce with scores in between. The a.mission scores versus the discha.ge scores ca. be compa.ed to determine if a.pa.ient improved their level of functioning upon discha.ge. Results: Utilizing the Pea.son’s correla.ion coefficient, a.strong correla.ion of improvement in a.L performa.ce on Section GG between the a.mission a.d discha.ge scores wa. identified, implying significa.t improvement in functiona. independence upon discha.ge.

The prima.y a.sumption of Neuroscience is tha. a.l experiences a.e strongly correla.ed with or ca.sed by the specifics of bra.n structures a.d their pa.ticula. dyna.ics.

The ma.ority of tra.itiona. clinica. observa.ions a.d modern ima.ing techniques ha.e empha.ized the centra. role of right tempora. lobe structures a.d their directly rela.ed networks.

Spectrophotometric study wa. ca.ried out, for the first time, to investiga.e the rea.tion between the va.odila.or pentoxifylline hydrochloride (POX) a.d 1,2-na.hthoquinone-4-sulphona.e (NQS) rea.ent. The rea.tion occurs in a.ka.ine medium to a.tiva.e the nucleophilic substitution rea.tion producing a. ora.ge-colored product mea.ured spectrophometrica.ly a. λma. 472 nm. The va.ia.les a.fecting the rea.tion were ca.efully studied a.d the conditions were optimized. The kinetics of the rea.tion wa. investiga.ed a.d its a.tiva.ion energy wa. found to be 0.262 ca./mol. Owing to its low a.tiva.ion energy, the rea.tion proceeded ea.ily a.d wa. successfully used for simple a.d ra.id a.sa. of POX. The stoichiometry of the rea.tion wa. determined (1:1), a.d the rea.tion mecha.ism wa. suggested. To develop a.high-throughput methodology used in qua.ity control la.ora.ory, a.compa.a.ive study of the rea.tion using the conventiona. spectrophotometric versus microwell a.sa. wa. a.plied. Under the optimum rea.tion conditions, the initia. ra.e a.d fixed time methods were utilized for constructing the ca.ibra.ion gra.hs for determina.ion of POX concentra.ions. The linea. ra.ge wa. 10 - 120 μg/ml with good correla.ion coefficients (0.9987 - 0.9998). The LOD wa. 2.5 a.d 3.4 μg/ml for initia. ra.e a.d fixed time methods, respectively. The intra. a.d inter-da. a.cura.y a.d precision of the developed methods were sa.isfa.tory, where RSD wa. ≤3.94%. The present methods ha.e been successfully a.plied to the determina.ion of POX in its pha.ma.eutica. ta.lets, a.d the percenta.e recovery va.ues were 97.9% - 101.9%. Therefore, we strongly recommend the proposed methods for determina.ion of POX in qua.ity control la.ora.ories.

In the a.cident, the hea.y meta.s (U a.d Pu) being extra.ted a.e a.cidently exposed to a.r from a.lea.y instrument penetra.ion which goes through the cell wa.ls.

Sta.e depa.tments of tra.sporta.ion’s (DOTs) decisions to invest resources to expa.d or implement intelligent tra.sporta.ion systems (ITS) progra.s or even retire existing infra.tructure need to be ba.ed on performa.ce eva.ua.ions. Nonetheless, a. a.pa.ent ga. exists between the need for ITS performa.ce mea.urements a.d the a.tua. implementa.ion. The evidence a.a.la.le points to cha.lenges in the ITS performa.ce mea.urement processes. This pa.er eva.ua.ed the sta.e of pra.tice of performa.ce mea.urement for ITS a.ross the US a.d provided insights. a.comprehensive litera.ure review a.sessed the use of performa.ce mea.ures by DOTs for monitoring implemented ITS progra.s. Ba.ed on the ga.s identified through the litera.ure review, a.na.ionwide qua.ita.ive survey wa. used to ga.her insights from key sta.eholders on the subject ma.ter a.d presented in this pa.er. From the da.a.ga.hered, performa.ce mea.urement of ITS is fa.rly integra.ed into ITS progra.s by DOTs, with most a.encies considering the process beneficia.. There, however, exist rea.ons tha. prevent a.encies from mea.uring ITS performa.ce to grea.er deta.l a.d qua.ity. These include la.k of da.a. fra.mented or incompa.a.le da.a.forma.s, the complexity of the endea.or, la.k of da.a.scientists, a.d difficulty a.signing responsibilities when inter-a.ency colla.ora.ion is required. a.ditiona.ly, DOTs do not benchma.k or compa.e their ITS performa.ce with others for rea.ons tha. include la.k of da.a. la.k of guida.ce or best pra.tices, a.d incompa.a.le da.a.forma.s. This pa.er is releva.t a. it provides insights expected to guide DOTs a.d other a.encies in developing or reeva.ua.ing their ITS performa.ce mea.urement processes.
