The Impacts of Politicization on Public Health Workers: The COVID-19 Pandemic in Oregon and Montana.

Context: The contributions from the field of public health to human society are numerous and are often taken for granted. The COVID-19 pandemic thrust the largely invisible public health workforce into the public eye. Like other career civil servants at the intersection of the citizen-state encounter, reports of uncooperative, hostile, and even violent confrontations between public health workers and those they serve are on the rise.

Stabilizing Effect of a 4c/6e Hypervalent Bond in Dinitrodiphenyl Disulfides and Their Thermochemical Properties: Experimental and Computational Approach.

Thermochemical properties and intramolecular interactions of 2,2'-dinitrodiphenyl disulfide (2DNDPDS) and 4,4'-dinitrodiphenyl disulfide (4DNDPDS) were determined and analyzed. Their standard molar formation enthalpies in the gas phase (Δ(g)'s) were experimentally determined; theoretically, they were computed using the G4 composite method and atomization reactions. Specifically, Δ(g)'s were obtained by combining formation enthalpies in the condensed phase and enthalpies of phase change.

Thermochemical Study of 1-Methylhydantoin.

Using static bomb combustion calorimetry, the combustion energy of 1-methylhydantoin was obtained, from which the standard molar enthalpy of formation of the crystalline phase at = 298.15 K of the compound studied was calculated. Through thermogravimetry, mass loss rates were measured as a function of temperature, from which the enthalpy of vaporization was calculated.

Assessment of Aflatoxin M1 and M2 exposure risk through Oaxaca cheese consumption in southeastern Mexico.

The present study evaluated the exposure of Southeast Mexican population to Aflatoxin M1 (AFM1) and M2 (AFM2) through the consumption of Oaxaca cheese. The intake of Oaxaca cheese was assessed via a food 7-day dairy questionnaire (N = 1100, 2014 and 2015). Thirty Oaxaca cheeses were randomly sampled, and the origin of the samples was also investigated.

The Intramolecular Hydrogen Bond N-H···S in 2,2'-Diaminodiphenyl Disulfide: Experimental and Computational Thermochemistry.

The intramolecular hydrogen bond of the N-H···S type has been investigated sparingly by thermochemical and computational methods. In order to study this interaction, the standard molar enthalpies of formation in gaseous phase of diphenyl disulfide, 2,2'-diaminodiphenyl disulfide and 4,4'-diaminodiphenyl disulfide at T = 298.15 K were determined by experimental thermochemical methods and computational calculations.
