1. Dietary risk assessment of fluoride, lead, chromium, and cadmium through consumption of Tieguanyin tea and white tea
Abstract Food and beverage consumption is the most possible route of human exposure to undesirable elements. Tieguanyin tea and white tea are widely-consumed beverage, which may be contaminated by fluoride (F), lead (Pb), chromium (Cr), and cadmium (Cd). For this study, the contamination levels and dietary exposure risks of these elements were studied from 7

2. Do climate changes alter the distribution and transmission of malaria? Evidence assessment and recommendations for future studies
Abstract Malaria, a mosquito-borne infectious disease, is considered a significant global health burden. Climate changes or different weather conditions may impact infectious diseases, specifically those transmitted by insect vectors and contaminated water. Based on the current predictions for climate change associated with the increase in carbon dioxide con

4. Characterization of Some Efficient Cellulase Producing Bacteria Isolated from Pulp and Paper Mill Effluent Contaminated Soil
ABSTRACT The wide variety of bacteria in the environment permits screening for more efficient cellulases to help overcome current challenges in biofuels production. This study focuses on the isolation of efficient cellulase producing bacteria found in pulp and paper mill effluent contaminated soil which can be considered for use in large scale biorefining. F

5. Interactions between plant hormones and heavy metals responses
Abstract Heavy metals are natural non-biodegradable constituents of the Earth's crust that accumulate and persist indefinitely in the ecosystem as a result of human activities. Since the industrial revolution, the concentration of cadmium, arsenic, lead, mercury and zinc, amongst others, have increasingly contaminated soil and water resources, leading to sig

6. Evaluation of the microbiological quality of ricotta cheese commercialized in Santa Catarina, Brazil
Abstract Ricotta cheese has low fat and salt contents and a high quantity of proteins. The diversity of the nutrients and the high water content are factors that favor the development of microorganisms in this product. In this context, the aim of this study was to evaluate the microbiological quality of ricotta commercialized in the western region of Santa C

7. Serotypes of Salmonella in Broiler Carcasses Marketed at Ibague, Colombia.
ABSTRACT Salmonella enterica is a large group of Gram-negative bacteria responsible for a number of foodborne infections associated with the consumption of contaminated poultry products. The hygienic status of raw chicken meat marketed at Ibague, Tolima, Colombia, is currently unknown. To address this issue, a cross-sectional study was conducted to estimate

8. Influence of lubricant oil residual fraction on recycled high density polyethylene properties and plastic packaging reverse logistics proposal
Abstract To recycle post-consumer HDPE contaminated with waste lubricating oils, companies include prior washing and drying in the process. This consumes large amounts of water and energy, generates significant effluent requiring treatment. This study assesses lubricating oil influence on HDPE properties to evaluate the feasibility of its direct mechanical r

9. Elimination of coliforms and Salmonella spp. in sheep meat by gamma irradiation treatment
This study aimed at evaluating the bacteriological effects of the treatment of sheep meat contaminated with total coliforms, coliforms at 45 °C and Salmonella spp. by using irradiation at doses of 3 kGy and 5 kGy. Thirty sheep meat samples were collected from animals located in Rio de Janeiro State, Brazil, and then grouped in three lots including 10 sample

10. Evaluation of the PetrifilmTM EB and TEMPO® EB systems with ISO 21528-2:2004 method for the count of Enterobacteriaceae in milk
The development of alternative microbiological techniques is driven by the necessity to meet the current needs to deliver rapid results in the manufacturing process of foods, but it is important that these methods be evaluated for each application. The objective of the present study was to assess the PetrifilmTM EB and the TEMPO® EB systems with ISO 21528-2

12. Reflexões sobre a relação entre a personalidade bordeline e as adicções / Thoughts on the relation between borderline personality and addictions
Compulsive behavior, acting out pathologies and feelings of emptiness are increasingly frequent in contemporary psychoanalytical practice. Such symptoms are contaminated or even brought forth by the pressure of strongly rooted ideals of current culture regarding consumerism and its void promises of providing inner fulfillment. The result becomes even more ev
