FORMULATION AND EVALUATION OF GEL MASK PEEL OF BLACK GLUTINOUS RICE EXTRACT (ORYZA SATIVA VAR GLUTINOSA) AND GREEN TEA (CAMELIA SINENSIS)

Introduction: Black glutinous rice (Oriza sativa var glutinosa) and green tea (Camelia sinensis) are plants that are useful for moisturizing the skin. The purpose of this study was to obtain the best formulation of peel-off gel mask preparations from black glutinous rice and green tea extract. Method: The gel mask formulation was made on the basis of variations in the concentration of Hydroxy Propyl Methyl Cellulose (HPMC) of F1 (2,5%), F2 (3%) and F3 (3,5%) with evaluation including organoleptic tests, pH, viscosity, homogenity, dispersity test, and drying time at temperatures of 4oC, 25oC, 40oC for 28 days. Results: The evaluation results of the three formulations met the requirements for a good peel-off gel mask. pH results are between 4.6-5.5 which is still in the standard range of 4.5-6.0. The results of the viscosity test are 6.500-12.166.7 cps which are in the range of 6.000-24.000 cps, the dispersion area meets the requirements of 5-7 cm, the result of the drying time is 15-22 minutes which are in the range of 15-30 minutes. Conclusion: The conclusion of this study was that F1, F2, and F3 met all the requirements for peel off gel masks by storing at temperatures of 4oC, 25oC, 40oC for 28 days.

WETLANDS CONSTRUÍDOS COM MEIO SUPORTE DE SOLO NA REMOÇÃO DE COLIFORMES TERMOTOLERANTES DE ESGOTOS DOMÉSTICOS

<p>O trabalho avaliou o desempenho dos <em>wetlands</em> construídos de fluxo vertical (WCFV) com meio suporte de solo misturado com areia na remoção de coliformes termotolerantes (CTer). O experimento era composto por dois sistemas: 1. Monocultura: Latossolo vermelho-amarelo plantado com a cultura do arroz (<em>Oriza sativa</em> L), operado com diferente taxa de aplicação de hidráulica (TAH) de esgoto de 4 cm/d, 8 cm/d e 15 cm/d; 2. Policultura: Latossolo amarelo plantado com as culturas do arroz (<em>Oriza sativa</em> L), do feijão (<em>Phaseolus vulgaris</em> L) e do milho (<em>Zea mays</em>), operado com TAH de 2,4 cm/d e 4,7 cm/d. As eficiências de remoção de CTer variaram, respectivamente, de 87,8% a 100% e 97,8% a 100% nos sistemas 1 e 2. Os fatores que contribuíram para a remoção de CTer foram a baixa umidade, o baixo teor de matéria orgânica e a colmatação. Os dois solos se mostraram eficientes na remoção de CTer. A rotação de culturas proporcionou uma remoção maior e em um período mais longo de tempo de operação, além de ter contribuído para um maior controle a colmatação do solo. Independentemente do tipo de solo e dele estar sendo cultivado com monocultura ou policultura, nos primeiros cinco meses de operação dos sistemas (1º ciclo), as TAH mais baixa favoreceram uma maior remoção de CTer com maior variabilidade nas eficiências de remoção. Com a continuidade da aplicação do esgoto para tratamento (2º ciclo), as eficiências de remoção reduziram e se tornaram aproximadamente constantes, sendo maiores quando se utilizou maior TAH.</p><p><strong>Palavras chaves:</strong> condutividade hidráulica; águas residuárias; microrganismos patogênicos; colmatação, rotatividade de culturas.</p><p> </p><p align="center">WETLANDS CONSTRUCTED WITH SOIL SUPPORT MEDIUM IN REMOVAL OF THERMOTOLERANT COLIFORMS FROM DOMESTIC SEWAGE</p><p><strong>Abstract</strong></p><p>The work evaluated the performance of constructed wetlands vertical flow (WCFV) with soil support medium mixed with sand in the removal of thermotolerant coliforms (ThC). The experiment consisted of two systems: 1. Monoculture: Red-yellow Latosol planted with rice (<em>Oriza sativa</em> L), operated with hydraulic application rates (HAR) of 4 cm/d, 8 cm/d and 15.0 cm/d; 2. Polyculture: Yellow Latosol planted with rice (<em>Oriza sativa</em> L), beans (<em>Phaseolus vulgaris</em> L) and maize (<em>Zea mays</em>), operated with HAR of 2.4 cm/d and 4.7 cm/d. ThC removal efficiencies ranged from 87.8 to 100% and 97.8 to 100%, respectively, in systems 1 and 2. The factors that contributed to the removal of ThC were low humidity, low organic matter and clogging. Both soils proved to be efficient in removing ThC. Crop rotation provided greater removal in a longer period of operation, in addition to controlling soil clogging. Regardless of the type of soil and whether it is being cultivated with monoculture or polyculture, in the first five months of operation of the systems (1st cycle), the lower HAR favored greater removal of ThC with greater variability in removal efficiency. With the continued application of sewage for treatment (2^nd cycle), the removal efficiencies reduced and became approximately constant, being higher for the highest HAR.</p><p><strong>Key words: </strong>hydraulic conductivity; wastewater; pathogenic microorganisms; clogging, crop rotation.</p>

Quality of drained waters of the irrigated rice frames during the establishment of pre-germinated cultivation system

Irrigated rice (Oriza sativa L.) pre-germinated production systems occupy approximately 100 thousand ha, annually cultivated in Rio Grande do Sul State, mainly in poorly drained areas, and with infestation of competing plants, especially red rice (Oriza sativa L.). This system constitutes the main technologic resource for rice crops produced on an ecological basis, by means of soil tillage and water management. Despite this, water outlets, specifically after seeding, have outstanding agronomic and environmental implications. Loss of nutrients and the physical and chemical quality of drained water have been questioned by public research and environmental institutions. This work evaluated the effects of different soil tillage systems and retention time of water in irrigated rice frames. The experiment was conducted in Viamão town, Rio Grande do Sul State. Two different soil tillage systems and four different times of frame drainage after seeding were investigated. Results showed that the main limiting attributes of water quality were turbidity, biochemical oxygen demand (BOD) and phosphorus (P) content, reaching 1800 TNU, 115 mg L-1, and 1.6 mg L-1, respectively. These attributes showed values higher than established environmental thresholds. Water quality was inappropriate to discharge directly into water courses, regardless of treatments.An alternative is the immediate placement in rice production areas, in more advanced development stages of plants. Pre-germinated rice crops require a system framework to avoid nutrient loss and consequent reduction of soil fertility.
