1. Determination of Ethyl Carbamate in Commercial Sweetened Sugar Cane Spirit by ESI-MS/MS Using Modified QuEChERS and 18-Crown-6/Trifluoroacetic Acid Spiking Additives
A fast, sensitive, and selective direct injection electrospray tandem mass spectrometry (DI ESI MS/MS) method that is able to quantify ethyl carbamate in commercial sweetened sugar cane spirit is described. The preparation method uses a modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) with potassium carbonate added to sweetened sugar cane

2. USE OF RESIDUES FROM THE CELLULOSE INDUSTRY AND SUGARCANE BAGASSE IN PARTICLEBOARDS
ABSTRACT The use of alternative materials such as lignocellulosic residues in the production of particleboards has increased considering that these residues are produced in large volumes and often do not have an appropriate destination. This research studied the use of residues from cellulose industries, sugarcane bagasse, and castor oil-based polyurethane r

3. Reliability and geotechnical safety applied to deep foundations in precast concrete piles - case study
Abstract The Brazilian standard pertinent to the design and execution of foundations, NBR 6122/2019, establishes that the safety inspection of foundations of a given project must be conducted based on compliance with specified safety factors. Safety factor verification is imperative to meet regulatory requirements; however, it is not enough to guarantee the

4. Simple GFAAS Method for Determination of Pb, As, and Cd in Cannabidiol Extracts Used for Therapeutic Purposes
Cannabis sativa has many promising medicinal applications for the mitigation, or even cure, of chronic diseases. The high bioaccumulation potential of C. sativa enables its use for the phytoremediation and detoxification of soil, may increase the levels of inorganic elements in products such as cannabidiol (CBD) extracts being necessary the evaluation/monito

5. Regenerated Cellulose Membrane from Peanut Shell for Biodiesel Purification
Biodiesel purification by water washing has been proved to be an unattractive process from an economic and environmental point of view. In this work, we propose the use of regenerated cellulose membranes from peanut shell as an alternative in the biodiesel purification. The preparation of the membranes was optimized from a central composite design, resulting

6. Sobrecarga térmica em áreas rurais: a influência da intensidade do trabalho
Resumo Introdução: a legislação brasileira determina que se monitore o Índice de Bulbo Úmido Termômetro de Globo (IBUTG) nos ambientes de trabalho em que o calor possa representar risco à saúde dos trabalhadores. Porém, esse monitoramento e a adoção de medidas preventivas não são comumente observados. Objetivo: identificar e mapear a influ�

8. Effect of Job Rotation on the Risk of Developing Ul-WMSDS in Poultry Slaughterhouse Workers
ABSTRACT This study analyzed the effect of job rotation on the risk of developing UL-WMSDs in a poultry slaughterhouse with 1,200 workers. Three organizational settings were evaluated (“without job rotation”, “with job rotation - tasks >1h” and “with job rotation - tasks <1h”) using the OCRA Checklist method and the fulfillment of requirements fo

9. Um método de ensaio para determinação da concentração de óleo em amostras de águas contaminadas com óleos e graxas
RESUMO A concentração de óleos e graxas em amostras de águas contaminadas com resíduos oleosos pode ser determinada pelos procedimentos estabelecidos no Standard Methods for the Examination of Water and Wastewater. No entanto, sua aplicação nem sempre resulta em valores adequados ou níveis de precisão satisfatórios para atendimento de padrões norm

11. A stochastic approach for measuring the uncertainty of claims reserves
RESUMO Este trabalho visa a obter métricas para a quantificação da variabilidade das provisões técnicas de sinistros, fazendo uso de modelos determinísticos e estocásticos. Em suma, tudo o que os métodos tradicionais não fornecem (medidas de variabilidade e de insuficiência de capital) são de fundamental importância para uma gestão atuarial efic

12. Cardiac function and intracellular Ca2+ handling proteins are not impaired by high-saturated-fat diet-induced obesity
Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in myocardial calcium (Ca2+) handling, the aim of this study was to t
