Tecnologias de captação e aproveitamento de água de chuva para residências uni familiares

Water scarcity is becoming an increasing problem and more evident worldwide, rainwater utilization is characterized for being one of the simplest and cheapest solutions to preserve drinking water and is a known alternative technology and used to promote sustainability in buildings and reducing pressure on surface waters, it would also reduce runoff and can minimize flooding. The rainwater, while not potable may be used in potable water usage activities, and may thus saving 30 to 40% of potable water. In this work one can see the importance of the capture and use of rainwater (CAAC), bringing economy, to reduce consumption of potable water, reducing the problem of water shortage, and which methods and materials needed to cause its implementation. The work also promoted the characterization of rainwater in the city of Guaratinguetá (SP) and studied its potential use in public housing, calculating the volume needed for implementation of the tank and the cost to implement all rainwater utilization system, but because it is a region with a median rainfall index and the popular houses present an area of small water capitation, the result was not satisfactory. The cost for implementation was high and the financial return was well above average. The government should encourage and support more CAAC, as not thinking about the financial side is advisable to be widespread throughout the country, the benefits it can bring

Chemopreventive activity of systemically administered curcumin on oral cancer in the 4-nitroquinoline 1-oxide model

Curcumin has therapeutic potential in preventing several types of cancer, including colon, liver, prostate, and breast. The goal of this study was to evaluate the chemopreventive activity of systemically administered curcumin on oral carcinogenesis induced by 4-nitroquinolone-1-oxide (4-NQO). A total of 50 male albino rats, Rattus norvegicus, (Holtzman), were divided into five groups (n=10 per group). Four of these groups were exposed to 50 ppm 4-NQO in their drinking water ad libitum for 8 or 12 weeks, two groups were treated with curcumin by oral gavage at 30 or 100 mg/kg per day, and one group was treated with corn oil (vehicle) only. The negative control group was euthanized at baseline. Tongues of all animals were removed after euthanasia and used in the subsequent analysis because the tongue is the primary site of carcinogenesis in this model. Descriptive histological analysis and immunohistochemistry for PCNA, Bcl-2, SOCS1 e-3, and STAT3 were performed to assess the oncogenic process. The gene expression of Vimentin, E-cadherin, N-cadherin, or TWIST1 was assessed using RT-qPCR as a representative of epithelial-mesenchymal transition (EMT) events. The administration of curcumin at 100 mg/kg during the 12 weeks markedly decreased the expression of PCNA, Bcl-2, SOCS1 e -3, and STAT3. Curcumin also minimized the cellular atypia under microscopic analysis and diminished the expression of the genes associated with EMT. These findings demonstrate that the systemic administration of curcumin has chemopreventive activity during oral carcinogenesis induced by 4-NQO.

Photocatalytic and photoelectrochemical inactivation of Escherichia coli and Staphylococcus aureus

Water disinfection usually requires expensive chemicals or equipment. Chlorination is a common disinfection method, although it is not able to inactivate all pathogens. High concentrations of residual chlorine also cause an unpleasant taste and smell in drinking water. As an alternative, photocatalysis and photoelectrochemical treatment has a high disinfection potential in drinking water by using solid catalysts, such as titanium dioxide. Highly reactive hydroxyl radical generated during the process serves as the main oxidant, capable of inactivating a wide range of microorganisms. In this study, we proposed a novel comparison between Gram-positive and gram-negative microorganisms. An immobilized TiO2 film promoted higher efficiency in water disinfection processes. The treatment effectively inactivated Escherichia coli and Staphylococcus aureus bacterial microorganisms in a shorter period than other alternative methods.
