The study presents experimental results determining the free chlorine content by UV-Vis absorption spectrophotometry using a calibration curve with the standard solution NaOCl. The chlorine in exists an aqueous solution as HOCl and OCl- depending on pH of media, that are knowm as free chlorine. The maximum absorption wavelengthts of OCl- and HOCl in aqueous media formed from sodium hypochlotrate are 291 and 292 respetively. Based on these wavelenghts OCl- and HOCl content might be determined using UV-Vis absorpton spectrophotometric method resulted in good data.

The semiarid region of Brazil is one of the main characteristics the average index of precipitation below 800mm per year and covers a large part of the Northeast region, leading the urban populations to the rationing of water. This work proposes the application of a constructive methodology for homes, so that this can become high enough in water. It was taken as a case study, the city of Pompeii in Paraiba - Brazil. This work presents a study of the potential for storing rainwater for residences, with a view to verify the viability of a project sustainable construction.

In recent times, Interior design practices have seen a dramatic shift with design strategies, which is focusing on providing healthy and sustainable indoor environments for the occupants. Interior designers feel compelled and can easily make a positive difference to the environmental problems extenuating it through their design choices to pursue sustainable design solutionsfor the given space.

The pure film of polymer (PVA) and films filled with Manganese Chloride (MnCl2.4H2O) salt with different weight ratios ((1,3,5,7,9,11,13,15) wt%) have been prepared by using casting method. The thermal and dielectric properties of (PVA-Manganese Chloride) composites films have been studied.

Sodium nitrite (NaNO2) presents in vegetables and is routinely used as a color fixative and as a preservative for meat and fish. Chronic ingestion of NaNO2 induced abnormalities in the biochemical parameters associated with the oxidative stress. The present study was carried out to investigate the protective efficacy of alpha lipoic acid (ALA) on the liver and kidney function tests and the oxidative stress alteration induced by NaNO2 in male albino rats; moreover the microscopical examination was studied.

Consumed worldwide, coffee is a very popular drink, with distinctive aroma and flavor. Coffee beverage is produced from ripe fruit of known species of the genus Coffea, in which Coffeaarabica, Coffealiberica and Coffearobusta stand out. Coffee quality is defined by a set of physical, chemical, sensory and safety attributes, able to meet the taste of different types of consumers. This study analyzed six samples of coffees, three with registration: Sample A, Sample B and Sample C, and three without registration of ANVISA: Sample A. Sample B and Sample C.

Introduction: Non-small cell tumor is the most common type of lung carcinoma and the treatment involves surgery, chemotherapy, and radiation therapy. In this sense, the search for new chemical substances with characteristics of selectivity, effectiveness and low toxicity have been investigated in the treatment of cancer. Studies show that sericin, a protein extracted from silkworm cocoons, has antitumor and pro-apoptotic activity. Objective: To analyze the potential antitumor effect of sericin on non-small cell lung cancer cell line.

Resistant varieties developed through plant breeding have made much contribution to Agriculture. This is because stability in crop production depends more on resistant varieties. Based on this, detailed review on the cytoplasm resistance and cytoplasm defense was carried out to enable Plant breeders develop yam genotypes with acquired disease resistance. Therefore yam plants that failed to inherit resistance genes could be made to acquire cytolasmic resistance mechanisms through field evaluation in hotspot agro ecologies.

The sustainability of organic rice agribusiness is determined by the performance of the agribusiness system consisting of subsystems providing production inputs, on-farm subsystems, processing/ handling results subsystems, marketing subsystems and supporting element subsystems. In Indonesia, especially East Priangan is known as an area of organic rice development. Currently, the development performance shows a decrease in indicators including productivity, production, planting area and the number of farmers involved in organic rice cultivation.

Objectives: This study aimed to obtain information about the dietary pattern and feeding problems of autistic children in Mumbai. Methods: It was a cross sectional study conducted on autistic children from various special schools in Mumbai. Fifty autistic and fifty age and gender matched typically developing (TD) children were selected for the study. The age group of children was 5-15 years. General information, details about their eating behavior and food habits of the children was collected from parents using a questionnaire.
