The im.act of arterial narrowing/blocking caused.by plaque build.p in arteries lead. to m.ny life-threatening consequences. This is recognized.as a cause in heart attacks and.peripheral vascular d.sease. d.agnosing the illness is only feasible after sym.tom. have presented.to the patient. Currently, the stand.rd.for visualizing coronary arteries is through angiography, which m.y have com.lications, and.im.act on the healthcare system. Furtherm.re, card.ac catheterization m.y also places high health risks, given its overall invasiveness. Card.ac arrhythm.as, infection, and.contrast d.e nephrotoxicity are recognized.com.lications within this process. Therefore, a noninvasive approach m.y have potentials to red.ce patient com.lications, finances surround.ng healthcare, and.m.re efficient patient care through earlier screening and.d.agnosing. This research ad.resses a new approach using photoacoustic (PA) im.ging. The transm.ssion properties of atherosclerosis within walls of arteries, can be exploited.using photo acoustics, to better visualize and.characterize the d.gree and.severity of atherosclerosis. The d.livered.energy is absorbed.by com.onents of the vascular tissue converted.into heat, lead.ng to transient therm.s elastic expansion, which creates an acoustic em.ssion. The therm.l response was analyzed.for its fall and.recovery tim.s that are attributed.to the artery fat type. The control param.ters, includ.ng the frequency, penetration d.pth, energy levels, and.tissue layer sizes, for m.ltilayered.structures were consid.red. The structures investigated.were fatty infiltrate within the artery, blood. bones, and.skin, within frequency range from.1 m.z to 3 m.z, and.typical tissue sizes in the m.lli to centim.ter range. As high as 14 m.as in the acoustic pressure at 1 m.z, resulted.in tem.erature d.fference of up to 3.4 K. When the operating frequency was altered.to 2 m.z, the tem.erature changed.to 23 K.

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.

Asbestos Exposure d.ring Gasket Rem.val from.Aircraft Engine

作者： Charles L. Blake Kevin m. Guth Raym.nd.d. Harbison Apex Com.anies Marietta USA Center for Environm.ntal and.Occupational Risk Analysis and.m.nagem.nt College of Public Health University of South Florida Tampa USA

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].
