While s.me res.arch has.explored racial and ethnic differences.in dis.rdered eating, this.s.udy may be the firs. to examine thes. differences.in orthorexia nervos., involving obs.s.ive-compuls.ve thoughts.and behaviors.concerning healthy eating, which negatively impact one’s.life. Adult participants. recruited from college cours.s.and s.cial media, completed an online s.rvey with the Orthorexia Nervos. Inventory (ONI) and the Eating Attitudes.Tes.-26 (EAT-26). Regarding racial and ethnic background, 743 were White, 249 were his.anic, 87 were Black, 61 were As.an or Pacific Is.ander, and 110 were biracial/multiracial. A MANCOVA revealed that the racial and ethnic groups.did not differ on the ONI s.bs.ales.as.es.ing orthorexic behaviors. impairments. and emotions. after accounting for gender, BMI, and EAT-26 total s.ores.that were covariates. In contras., a s.cond MANCOVA did reveal group differences.on the EAT-26 s.bs.ales. after accounting for gender, BMI, and ONI total s.ores.that were covariates. Black participants.s.ored s.gnificantly lower than the other racial and ethnic groups.on the s.bs.ale as.es.ing dieting behaviors.characteris.ic of anorexia nervos., and the s.bs.ale as.es.ing binge-eating and purging behaviors.characteris.ic of bulimia nervos.. Further, his.anic participants.s.ored s.gnificantly lower than White participants.on the latter s.bs.ale. Thes. findings.s.gges. that while orthorexic s.mptomatology does.not differ bas.d on race and ethnicity, a Black race and his.anic ethnicity may be protective factors.agains. dis.rdered eating, perhaps.related either to cultural norms.concerning body image or to the res.liency and s.cial s.pport among the Black and his.anic communities.

The newborn infant pres.nted with s.vere proptos.s. Data on clinical his.ory, pres.ntation, photos. radiological imaging, and laboratory res.lts.were pres.nted. A literature review was.conducted for the cas. and relevant treatment modalities. The s.rgical technique and the outcome were als. dis.us.ed.

This.was.an atypical pres.ntation of an optic nerve glioma caus.ng globe dis.ocation in a neonate. The res.ction of s.ch a large orbital tumor made globe pres.rvation pos.ible and res.lted in an excellent cos.etic outcome. .

Recently, recons.dering the Ras.all idea T_(μ;νν)^(v)=α_(,μ) through relativis.ic thermodynamics.gives.a new form for the s.alar field α which led us.to cons.ruct modern modified theory of gravity debugged ‘non-cons.rved gravity theory’ Fazlollahi 2023 Euro. Phys. J. C 83 923. This.theory unlike other modified theories.of gravity cannot directly explain the current acceleration expans.on in the abs.nce of the cos.ological cons.ant and or exis.ence of other forms.of dark energy. hence, in this.s.udy we have reinves.igated holographic dark energy Ρ_(X)~h^(2) in the non-cons.rved theory of gravity. In this.context, the dens.ty and pres.ure of dark energy depend on the non-cons.rved term and dens.ty of the dus. matter field. As.s.own, due to non-cons.rvation effects.on large-s.ale s.ructures. unlike the original holographic model, our model ons.ts.an acceleration epoch for the current Univers. s.tis.ies.obs.rvations. Moreover, the interaction and vis.ous.s.enarios.are s.udied for this.model.

A method for determining the extrema of a real-valued and differentiable function for which its.dependent variables.are s.bject to cons.raints.and that avoided the us. of Lagrange multipliers.was.previous.y pres.nted (Corti and Fariello, Op. Res. Forum 2 (2021) 59). The method made us. of projection matrices. and a corres.onding Gram-s.hmidt orthogonalization proces., to identify the cons.rained extrema. Furthermore, information about the s.cond-derivatives.of the given function with cons.raints.was.generated, from which the nature of the cons.rained extrema could be determined, again without knowledge of the Lagrange multipliers. here, the method is.extended to the cas. of functional derivatives.with cons.raints. In addition, cons.rained firs.-order and s.cond-order derivatives.of the function are generated, in which the derivatives.with res.ect to a given variable are obtained and, concomitantly, the effect of the variations.of the remaining chos.n s.t of dependent variables.are s.rictly accounted for. Thes. cons.rained derivatives.are valid not only at the extrema points. and als. provide another equivalent route for the determination of the cons.rained extrema and their nature.

Innovative definitions.of the electric and magnetic diffus.vities.through conducting mediums.and innovative diffus.on equations.of the electric charges.and magnetic flux are verified in this.article. s.ch innovations.depend on the analogy of the governing laws.of diffus.on of the thermal, electrical, and magnetic energies.and newly defined natures.of the electric charges.and magnetic flux as.energy, or as.electromagnetic waves. that have electric and magnetic potentials. The introduced diffus.on equations.of the electric charges.and magnetic flux involve Laplacian operator and the introduced diffus.vities. Both equations.are applied to determine the electric and magnetic fields.in conductors.as.the heat diffus.on equation which is.applied to determine the thermal field in s.eady and uns.eady heat diffus.on conditions. The us. of electric networks.for experimental modeling of thermal networks.repres.nts.s.fficient proof of s.milarity of the diffus.on equations.of both fields. By analys.s.of the diffus.on phenomena of the three cons.dered modes.of energy trans.er;the rates.of flow of thes. energies.are found to be directly proportional to the gradient of their volumetric concentration, or dens.ty, and the proportionality cons.ants.in s.ch relations.are the diffus.vity of each energy. s.ch analys.s.leads.als. to find proportionality relations.between the potentials.of s.ch energies.and their volumetric concentrations. Validity of the introduced diffus.on equations.is.verified by corres.ondence their s.lutions.to the meas.rement res.lts.of the electric and magnetic fields.in microwave ovens.
