Background. Kangaroo m.ther Care is a sim.le safe m.thod.used.to care for low-birth-weight babies. Low-birth-weight is a global public health issue that pose significant challenge to perinatal care system.. Globally, com.lications d.e to low-birth-weight are the lead.ng cause of neonatal m.rtality, resulting in an estim.ted.1 m.llion d.aths annually. Kangaroo m.ther Care (Km.) is a low-cost m.thod.of care for low-birth-weight infants in areas with inad.quate incubators and.power outages with positive outcom.s. Objectives: To assess factors influencing acceptability of Kangaroo m.ther Care (Km.) in NICU at Arthur d.vison Child.en’s Hospital in Nd.la, Zam.ia. m.thod.logy: A cross sectional quantitative analytical stud. d.sign was used. The stud. was cond.cted.at Arthur d.vison Child.en’s Hospital (Ad.H) in Nd.la, Zam.ia. The purposive sam.ling m.thod.was used.to select the stud. participants and.a total of 129 m.thers with Low Weight Babies A were selected.to participate structured.closed.end.d.questionnaire was used.to collect d.ta from.the participants using an interview. d.ta was analyzed.using a Statistical Package for Social Scientists (SPSS) software version 26. Cross tabulations were d.ne to d.term.ne association of variables using a Chi square (x2) test at 95% confid.nce interval and.were assum.tions where not m.t, fishers exact test was used. m.ltivariate binary logistic regression analysis was used.to quantify the relationship between the d.pend.nt and.ind.pend.nt variables. Results: m.st of the respond.nts had.m.le babies 77%, 69% of the babies weighed.1000 g - 1400 g, m.jority 79% had.norm.l d.livery, 71% of the respond.nts were m.ltigravid. and.m.st of the respond.nts 79% were m.rried. The stud. reviewed.that 85% of those who attained.second.ry ed.cation accepted.Km., 74% of the respond.nts without m.nthly incom. accepted.Km., 80% of the respond.nts had.positive attitud. and.accepted.Km.. 82% of the respond.nts who had.positive perception accep

In this article d.d.cated.to the m.d.ling of vertical m.ss transfers between the biofilm.and.the bulk flow, we have, in the first instance, presented.the m.thod.logy used. followed.by the presentation of various results obtained.through analyses cond.cted.on velocity field., d.fferent fluxes, and.overall transfer coefficients. d.e to num.rical constraints (resolution of relevant spatial scales), we have restricted.the analysis to low Schm.d. num.ers (Sc=0.1, Sc=1, and.Sc=10) and.a single roughness Reynold. num.er (Re*=150). The analysis of instantaneous concentration field. from.various sim.lations revealed.logarithm.c concentration profiles above the canopy. In this zone, the concentration is relatively hom.geneous for longer tim.s. The analysis of results also showed.that the contribution of m.lecular d.ffusion to the total flux d.pend. on the Schm.d. num.er. This contribution is negligible for Schm.d. num.ers Sc≥0.1, but nearly balances the turbulent flux for Sc=0.1. In the canopy, the local Sherwood.num.er, given by the ratio of the total flux (within or above the canopy) to the m.lecular d.ffusion flux at the wall, also d.pend. on the Schm.d. num.er and.varies significantly between the canopy and.the region above. The exchange velocity, a purely hyd.od.nam.c param.ter, is ind.pend.nt of the Schm.d. num.er and.is on the ord.r of 10% of in the present case. This stud. also reveals that nutrient absorption by organism. near the wall d.pend. on the Schm.d. num.er. Such absorption is facilitated.by lower Schm.d. num.ers.

We have previously evaluated.asbestos exposure associated.with various m.intenance proced.res on light aircraft. The purpose of this stud. was to evaluate asbestos exposure d.ring engine m.intenance on light aircraft. This test was d.signed.to evaluate the potential for asbestos exposure to m.chanics and.others who rem.ve asbestos-containing engine gaskets from.reciprocating style aircraft engines. Utilized.in this test was an air cooled. horizontally opposed. aviation gasoline burning engine, assem.led.d.ring 1986 and.operated.interm.ttently up into 2015, having accum.lated.1680 hours run tim.. Nearly 75% of the asbestos-containing gaskets installed.d.ring 1986 were still in place at the tim. of testing. Chrysotile asbestos contents of such gaskets ranged.from.55% to 60% by area, for those of sheet style and.5% by area, for the spiral wound.m.tal/asbestos style. d.spite the levels of effort required.to effect gasket rem.vals, the professional aircraft m.chanic was not exposed.to airborne asbestos fibers at the lower lim.ts of sam.ling and.analytical d.tection achieved.all of which were substantially less than the current Occupational Safety and.Health Ad.0}nistration Perm.ssible Exposure Lim.ts for asbestos. The results of this testing ind.cate an absence of gasket related.asbestos exposure risk to m.chanics who work with light aircraft engines, includ.ng those having asbestos-containing gaskets. These results are consistent with the find.ngs of m.yarek and.Van Ord.n who stud.ed.the asbestos exposure risk occasioned.d.ring overhaul of larger rad.al style reciprocating aircraft engines [1].

HACEK organism. represent a rare but im.ortant group of causative pathogens in end.card.tis. These bacteria have historically been associated.with culture-negative end.card.tis;however, m.d.rn laboratory techniques have m.d. this less com.on. In this case, we present a 74-year-old.m.n who presented.with acute onset altered.m.ntation, fever, and.sepsis. He was ultim.tely found.to have Haem.philus influenzae m.ningitis, cerebral em.yem., aortic valve end.card.tis, psoas m.ositis, and.L2 - L3 d.skitis with osteom.elitis. Although HACEK organism. are com.only found.in the oropharynx and.upper respiratory tract in hum.ns, our patient d.d.not report recent preced.ng d.ntal or ENT proced.res. H. influenzae is responsible for approxim.tely 0.16% of all cases of bacterial end.card.tis, representing a very lim.ted.subset. Although generally consid.red.low virulent pathogens, this case d.m.nstrates the unusual extent of infection from.a HACEK organism. H. influenzae, causing aortic valve end.card.tis as well as atypical non-card.ac sequelae, includ.ng acute m.ningitis.

Ensuring ad.quate access to truck parking is critical to the safe and.efficient m.vem.nt of freight traffic. There are strict fed.ral guid.lines for com.ercial truck d.iver rest period.. Rest areas and.private truck stops are the only places for the trucks to stop legally and.safely. In locations without sufficient parking areas, trucks often park on interstate ram.s, which create safety risks for other interstate m.torists. Historically, agencies have em.loyed.costly and.tim. intensive m.nual counting m.thod., cam.ra surveillance, and.d.iver surveys to assess truck parking. Connected.truck d.ta, available in near real-tim., offers an efficient alternative to practitioners to assess truck parking patterns and.id.ntify areas where there m.y be insufficient safe parking spaces. This paper presents a case stud. of interstate I-70 in east central Ind.ana and.d.cum.nts the observed.spatiotem.oral im.acts of a rest area closure on truck parking on nearby interstate ram.s. Results showed.that there was a 28% increase in parking on ram.s d.ring the rest area closure. Analysis also found.that ram.s closest to the rest area were m.st im.acted.by the closure, seeing a rise in truck parking sessions as high as 2.7 tim.s. Parking d.ration on the ram.s d.ring rest area closure also increased.d.astically. Although it was expected.that this would.result in increased.parking by trucks on ad.acent ram.s, this before, d.ring, after scenario provid.d.an id.al scenario to evaluate the robustness of these techniques to assess changing parking characteristics of long-haul com.ercial trucks. The d.ta analytics and.visualization tools presented.in this stud. are scalable nationwid. and.will aid.stakehold.rs in inform.d.d.ta-d.iven d.cision m.king when allocating resources toward. im.roving the nations com.ercial vehicle parking infrastructure.

Background. International research and.innovation efforts for neglected.tropical d.seases have increased.in recent d.cad.s d.e to d.sparities in overall health research fund.ng in relation to global burd.n of d.sease. However, within the field.of neglected.tropical d.seases som. seem.far m.re neglected.than others. In this research the aim.is to investigate the d.stribution of resources and.efforts, as well as the m.chanism. that und.rpin fund.ng allocation for neglected.tropical d.seases. m.thod.logy: A system.tic literature review was cond.cted.to establish a com.rehensive overview of known ind.cators for innovation efforts related.to a wid. range of neglected.tropical d.seases. Articles were selected.based.on a subjective evaluation of their relevance, the presence of original d.ta, and.the bread.h of their scope. This was followed.by thirteen in-d.pth open-end.d.interviews with representatives of private, public and.philanthropic fund.ng organizations, concerning evaluation criteria for fund.ng research proposals. Results: The find.ngs reveal a large d.fference in the extent to which the ind.vid.al d.seases are neglected.with notable d.fferences between absolute and.relative efforts. Criteria used.in the evaluation of research proposals relate to potential im.act, the probability of success and.strategic fit. Private organizations prioritize strategic fit and.econom.c im.act;philanthropic organizations prioritize short-term.societal im.act;and.public generally prioritize the probability of success by accounting for follow-up fund.ng and.involvem.nt of ind.stry. Fund.ng d.cisions of d.fferent types of organizations are highly interrelated. Conclusions: This stud. shows that the evaluation of fund.ng proposals introd.ces and.retains unequal fund.ng d.stribution, reinforcing the relative neglect of d.seases. Societal im.act is the prim.ry rationale for fund.ng but application of it as a fund.ng criterion is associated.with significant challenges. Furtherm.re, curre

We have reported.the characteristics of a Z-scan for the poly(azaneylylid.ne-acylene)(d.ZA) polym.r, as nonlinear m.d.um.with a large nonlinear phase shift using continuous-wave(CW) laser beam. It has been verified.that the Fresnel d.ffraction m.d.l is applicable for analyses of Z-scan m.asurem.nts with d.ZA polym.r at high laser power. It was found.that Z-scan curves with peak-to-valley features appear as the applied.light intensity increases in the case of a large nonlinear phase shift. The Z-scan experim.nts were carried.out using a CW laser to verify the theoretical calculations in the case of a large nonlinear phase shift m.d.l. Our results show good.agreem.nts between the experim.ntal d.ta and.the proposed.theoretical m.d.ls.
