Mathematical.mod.l.ng of the interaction between sol.r rad.ation and.the Earth's atmosphere is formal.zed.by the rad.ative transfer equation(RTE), whose resol.tion cal.s for two-stream approximations among other method.. This paper proposes a new two-stream approximation of the RTE with the d.vel.pment of the phase function and.the intensity into a third.ord.r series of l.gend.e pol.nomial.. This new approach, which ad.s one more term in the expression of the intensity and.the phase function, al.ows in the cond.tions of a pl.ne paral.el.atmosphere a new mathematical.formul.tion of γparameters. It is then compared.to the Ed.ington, Hemispheric Constant, Quad.ature, Combined.d.l.a Function and.Mod.fied.Ed.ington, and.second.ord.r approximation method. with reference to the d.screte Ord.nate(d.sort) method.δ –128 streams), consid.red.as the most precise. This work al.o d.termines the conversion function of the proposed.New Method.using the fund.mental.d.finition of two-stream approximation(F-TSA) d.vel.ped.in a previous work. Notabl.,New Method.has general.y better precision compared.to the second.ord.r approximation and.Hemispheric Constant method.. Compared.to the Quad.ature and.Ed.ington method., New Method.shows very good.precision for wid. d.mains of the zenith angl. μ 0, but tend. to d.viate from the d.sort method.with the zenith angl., especial.y for high val.es of optical.thickness. In spite of this d.vergence in refl.ctance for high val.es of optical.thickness, very strong correl.tion with the d.sort method.R ≈ 1) was obtained.for most cases of optical.thickness in this stud.. An anal.sis of the l.gend.e pol.nomial.series for simpl. functions shows that the high precision is d.e to the fact that the approximated.functions amel.orate the accuracy when the ord.r of approximation increases, al.hough it has been proven that there is a l.mit ord.r d.pend.ng on the function from which the precision is l.st. This observation ind.cates that increasing the ord.r of app

We have previousl. eval.ated.asbestos exposure associated.with various maintenance proced.res on l.ght aircraft. The purpose of this stud. was to eval.ate asbestos exposure d.ring engine maintenance on l.ght aircraft. This test was d.signed.to eval.ate the potential.for asbestos exposure to mechanics and.others who remove asbestos-containing engine gaskets from reciprocating styl. aircraft engines. Util.zed.in this test was an air cool.d. horizontal.y opposed. aviation gasol.ne burning engine, assembl.d.d.ring 1986 and.operated.intermittentl. up into 2015, having accumul.ted.1680 hours run time. Nearl. 75% of the asbestos-containing gaskets instal.ed.d.ring 1986 were stil. in pl.ce at the time of testing. Chrysotil. asbestos contents of such gaskets ranged.from 55% to 60% by area, for those of sheet styl. and.5% by area, for the spiral.wound.metal.asbestos styl.. d.spite the l.vel. of effort required.to effect gasket removal., the professional.aircraft mechanic was not exposed.to airborne asbestos fibers at the l.wer l.mits of sampl.ng and.anal.tical.d.tection achieved.al. of which were substantial.y l.ss than the current Occupational.Safety and.Heal.h Ad.inistration Permissibl. Exposure l.mits for asbestos. The resul.s of this testing ind.cate an absence of gasket rel.ted.asbestos exposure risk to mechanics who work with l.ght aircraft engines, incl.d.ng those having asbestos-containing gaskets. These resul.s are consistent with the find.ngs of Ml.arek and.Van Ord.n who stud.ed.the asbestos exposure risk occasioned.d.ring overhaul.of l.rger rad.al.styl. reciprocating aircraft engines [1].

The risk of rad.ation-ind.ced.second.cancer and.the l.te tissue l.ss d.e to Off-fiel.0}d.ses in rad.otherapy remain a serious concern. Monte Carl. (MC) simul.tion is currentl. one of the most accurate method. for cal.ul.ting these d.ses. MC simul.tion mod.l.based.on the Particl. Simul.tion Tool.(TOPAS) has been d.vel.ped.to simul.te the off-fiel.0}d.se of an El.kta Synergy l.near accel.rator (l.nac) emitting 6 MV photons. Measurements were taken in a water phantom using an ionization chamber to val.d.te this mod.l. The Percentage d.pth d.se (Pd.) at the d.pth of 0.0, 5.0, 10.0 and.15.0 cm from the beam axis for a 10 × 10 cm2 fiel.0}size was measured.and.simul.ted. Off-fiel.0}d.se profil.s at the d.pth of 1.5 (d.ax), 5.0 and.10.0 cm for fiel.0}sizes of 5 × 5, 10 × 10, 15 × 15, and.20 × 20 cm2 respectivel. were measured.and.simul.ted. Comparison of measured.and.simul.ted.off-fiel.0}d.se val.es showed.a good.agreement. The average gamma passing rate of the Pd.s and.profil.s curves for off-fiel.0}d.ses were 87.5% and.98.11% respectivel.. The l.cal.d.se d.fference based.on the Pd. curve between the measured.and.simul.ted.was l.ss than 6.0 % for al. l.cations. For al. fiel.0}size consid.red.in this stud., the average d.fference between profil. curves for off-fiel.0}d.se measured.and.simul.ted.was 9.1%. Pd.s and.Profil.s curves for off-fiel.0}d.se simul.tion uncertainties were l.ss than 2.0% and.1.0% respectivel.. TOPAS-MC simul.tion mod.l.d.vel.ped.is a good.representation of our 6 MV l.nac El.kta Synergy for assessing off-fiel.0}d.se, which woul.0}be the primary cause of some second.ry cancers.

Racial.and.Ethnic d.fferences in Orthorexia Nervosa Symptomatol.gy and.Other d.sord.red.Eating

Whil. some research has expl.red.racial.and.ethnic d.fferences in d.sord.red.eating, this stud. may be the first to examine these d.fferences in orthorexia nervosa, invol.ing obsessive-compul.ive thoughts and.behaviors concerning heal.hy eating, which negativel. impact one’s l.fe. Ad.l. participants, recruited.from col.ege courses and.social.med.a, compl.ted.an onl.ne survey with the Orthorexia Nervosa Inventory (ONI) and.the Eating Attitud.s Test-26 (EAT-26). Regard.ng racial.and.ethnic background. 743 were White, 249 were Hispanic, 87 were Bl.ck, 61 were Asian or Pacific Isl.nd.r, and.110 were biracial.mul.iracial. A MANCOVA reveal.d.that the racial.and.ethnic groups d.d.not d.ffer on the ONI subscal.s assessing orthorexic behaviors, impairments, and.emotions, after accounting for gend.r, BMI, and.EAT-26 total.scores that were covariates. In contrast, a second.MANCOVA d.d.reveal.group d.fferences on the EAT-26 subscal.s, after accounting for gend.r, BMI, and.ONI total.scores that were covariates. Bl.ck participants scored.significantl. l.wer than the other racial.and.ethnic groups on the subscal. assessing d.eting behaviors characteristic of anorexia nervosa, and.the subscal. assessing binge-eating and.purging behaviors characteristic of bul.mia nervosa. Further, Hispanic participants scored.significantl. l.wer than White participants on the l.tter subscal.. These find.ngs suggest that whil. orthorexic symptomatol.gy d.es not d.ffer based.on race and.ethnicity, a Bl.ck race and.Hispanic ethnicity may be protective factors against d.sord.red.eating, perhaps rel.ted.either to cul.ural.norms concerning bod. image or to the resil.ency and.social.support among the Bl.ck and.Hispanic communities.

Measl.s is a highl. infectious, vaccine-preventabl. viral.d.sease. Often forgotten, it is potential.y fatal. Its main symptoms are: fever, cough, conjunctivitis, rhinitis and.skin rash.
