AbstractIntroductionPersonal protective equipment (PPE) recommended for use in West Africa during the Ebola outbreak increased risk for heat illness, and countermeasures addressing this issue would be valuable.Hypothesis/ProblemThe purpose of this study was to examine the physiological impact and heat perception of four different personal cooling devices (PCDs) under impermeable PPE during low-intensity exercise in a hot and humid environment using thermal manikin modeling and human testing.MethodsSix healthy male subjects walked on a treadmill in a hot/humid environment (32°C/92% relative hum

Abstract:
Injectable pre-formed physical hydrogels provide many advantages for biomedical applications. Polyelectrolyte complexes (PEC) formed between cationic chitosan (CHT) and anionic polymers of cyclodextrin (PCD) render a hydrogel of great interest. Given the difference between water-soluble (PCDs) and water-insoluble PCD (PCDi) in the extension of polymerization, the present study aims to explore their impact on the formation and properties of CHT/PCD hydrogel obtained from the variable ratios of PCDi and PCDs in the formulation. Hydrogels CHT/PCDi/PCDs at weight ratios of 3:0:3, 3:1.5:1.5, and 3:

Abstract:
The fate of PCDDs, PCDFs, and PCBs in sewage sludges after different management techniques — such as agricultural application, land restoration, and marine disposal — was studied. Changes observed in the concentrations, in the ratio between PCDD and PCDF levels, and in the isomeric distribution suggest the influence of the sewage sludge on the sludge-treated areas (soils and sediments). Whereas land application techniques seem to produce no serious environmental consequences, marine disposal practices produce considerable increases in the levels of contamination in marine sediments.

Abstract:
In this study, we report the mercury ions (Hg[Formula: see text]) mediated phosphorus-containing carbon dots (PCDs) as a selective “off–on” fluorescence probe for glutathione (GSH), cysteine (Cys) and homocysteine (Hcys). PCDs obtained by hydrothermal reaction are sensitive to Hg[Formula: see text] ions and its fluorescence can be significantly quenched owing to the electron transfer from the lowest unoccupied molecular orbital (LUMO) of PCDs to Hg[Formula: see text]. Interestingly, the weak fluorescence of Hg[Formula: see text]-mediated PCDs could be gradually recovered with the addition of G

O estudo foi realizado em uma empresa referência em inclusão. Foram utilizados o Inventário de Concepções de Deficiência em Situações de Trabalho e o Inventário de Valores Organizacionais. Também foram feitas entrevistas com PcDs, seus gestores e coordenadores do programa de inclusão. Verificou-se que existe uma correlação negativa entre a percepção que a

Abstract:
The question of how to treat people with cognitive disabilities (PCDs) poses an important problem for Rawlsian theories of justice because it is unclear whether PCDs are included within the scope of moral personhood. Rawls’s Standard Solution focuses on nondisabled adults as the fundamental case, while later addressing PCDs as marginal cases. I claim that the Standard Solution has two weaknesses. First, it relies on a dichotomy between nondisabled and disabled that is tenuous and difficult to defend. Second, it makes the theory circular in a vicious way.I argue that Rawls’s theory can be revis

A study was undertaken of the PCDD and PCDF export vectors from a major facility that comprises a bleached kraft pulp mill, paper mills, and previously, a timber processing sawmill. The PCDD and PCDF levels in pulps, untreated effluent, the final effluent, sludges, and discharge to the receiving waters, were studied. The total toxic equivalents were calculated, and the individual PCDD and PCDF profiles showed that there were several contributing sources of dioxins. The various effluent streams that contribute to the final effluent were studied, including the bleached effluent, the other kraft

Analysis of the current state of the problem of the dioxins and polychlorinated biphenyls (PCBs) determination in baby food products and the development of sample preparation methods for determining these xenobiotics in food products for infants and young children. Dioxins form a group of structurally and chemically related chlorinated tricyclic oxygen-containing aromatic compounds (congeners), which includes 75 polychlorinated dibenzo-para-dioxins (PCDDs) and 135 polychlorinated dibenzofurans (PCDFs).

Abstract:
Porphin-based carbon dots (denoted as PCDs) are prepared through a one-step hydrothermal method by using meso-tetra (4-carboxyphenyl) porphin (TCPP), citric acid, and ethanediamine as precursor. PCDs give rise to the optimal photoluminescence at λex/λem = 375/645 nm, exhibit an excitation-independent property, excellent water solubility, and good biocompatibility, which provide red emission and avoid the autofluorescence as an efficient fluorescent imaging probe. On the other hand, when Eu3+ is added into PCDs, the carboxylate groups located on the surface of PCDs exhibit high affinity to Eu3+
