Circularity of Brazilian silk: Promoting a circular bioeconomy in the production of silk cocoons.

The bioeconomy is considered one of the three main sectors with the greatest opportunities for the development of the circular economy in Brazil, who is one of the largest silk producers in the world; and sericulture is an agribusiness that contributes greatly to the bioeconomy in Brazil. Therefore, this research aimed to identify opportunities for creating value by internalizing flows in the production of silk cocoons by promoting a circular bioeconomy. To that end, a tool was used to assess the circularity of the referred system.

Construct Validity and Reliability of the Work Environment Assessment Instrument WE-10.

The purpose of this study was to validate the construct and reliability of an instrument to assess the work environment as a single tool based on quality of life (QL), quality of work life (QWL), and organizational climate (OC). The methodology tested the construct validity through Exploratory Factor Analysis (EFA) and reliability through Cronbach's alpha. The EFA returned a Kaiser-Meyer-Olkin (KMO) value of 0.

Sustainability of sugarcane lignocellulosic biomass pretreatment for the production of bioethanol.

The sustainability of a biofuel is severely affected by the technological route of its production. Chemical pretreatment can be considered the traditional method of decomposition of the lignocellulose into its mono and oligomeric units, which can be further bioconverted to ethanol. The evaluation of the recent advances in chemical pretreatments of sugarcane bagasse, especially diluted acids, alkaline, organosolv and ionic liquids, identified the critical points for sustainability.

Five-Year Incidence of Hospital-Based Emergencies Related to Acute Recreational Intoxication in Minors.

Background: Alcohol or other drug (AOD) intoxication in minors is a public health challenge. We characterized underage patients admitted to an emergency department (ED) with acute, recreational AOD intoxication.

Methods: We conducted a 5-year (2012 to 2016) analysis of minors admitted to the only hospital-based pediatric ED in an urban area.

Life cycle assessment of medium-density fiberboard (MDF) manufacturing process in Brazil.

Brazil is one of the largest producers of medium-density fibreboard (MDF) in the world, and also the MDF has the highest domestic consumption and production rate in the country. MDF applications are highlighted into residential and commercial furniture design and also a wide participation in the building sector. This study aimed to propose ways of improving the environmental cradle-to-gate life-cycle of one cubic meter MDF panel by means of a life-cycle assessment (LCA) study.

Quality of life assessment in people with HIV: analysis of the WHOQOL-HIV syntax.

This study aims to analyze the syntax of the World Health Organization's quality of life HIV/AIDS instrument (WHOQOL-HIV), provided by the WHOQOL-HIV Group. As a result, errors and inconsistencies in the syntax of WHOQOL-HIV were found. In face of the fragility found, two new syntaxes for WHOQOL-HIV were proposed: (a) a correction of errors found in the original syntax; and (b) restructuration of the calculation of scores for WHOQOL-HIV, bringing it closer to the WHOQOL-100.
