The community awareness on responsible ownership associated with public policies is key to the promotion of animal welfare. Most cities have a large population of dogs and cats wandering causing serious health problems and abuse. This project aimed to guide and inform the population aimed at animal welfare with the simple and direct approach to issues related to responsible ownership, management, nature conservation and zoonoses. The methodology developed to approach the project in two modules: the I and II, along public and private Elementary and High Schools in Araçatuba. Module I (Mod.I) is basedon the use of puppet theater and musicals, considering the target audience children 3-10 years and the second module (Mod 2) consists of presentations of lectures by undergraduate and graduate course of Veterinary Medicine FMVA UNESP campus Araçatuba, being the target audience of High School teenagers. Data collection proceeded by questionnaires, with questions regarding the care and practices to pets. The results revealed that there is a lack of information about animal welfare practice.

This study aimed to map the classes of use and occupation and their conflicts in Areas of Permanent Preservation (APPs) in the basin of Ribeirão São Pedro - Botucatu (SP) with the use of remote sensing techniques - image obtained by satellite 2011 - and the use of GIS. For this, we used the GIS techniques, and the integration of information held in the Geographic Information System (GIS) - IDRISI, coupled with the use of digital maps, published by the Brazilian Institute of Geography and Statistics - IBGE, scale 1: 50,000 and satellite images LANDSAT - 5 (2011) sensor TM (Thematic Mapper) with spatial resolution of 30 x 30 meters, provided by the National Institute for Space Research (INPE) .The Geographic Information System (GIS) was used IDRISI Selva and software, CartaLinx. This work had as legal support environmental legislation, specifically, the Federal Law 12.651 / 12. Thus, the study of the watershed becomes an important tool to understand its dynamics in relation to the use and occupation of their area and to characterize their environmental problems and taking as legal counsel to the preservation and conservation of the land to support environmental legislation.

This study aimed to evaluate the hydrothermal effect on conservation of two jabuticaba fruits, Myrciaria jabuticaba Vell. Berg. Fruits were subjected to thermal treatment by 10 min at 5, 10, 15, 20 and 25 ºC and wrapped into expanded polystyrene trays, stored at 9 ºC and 85-90% RH, being evaluated every 5 d. Shelf life, weight loss, respiratory rate, soluble solids, titrable acidity, texture, C vitamin, pH, total and soluble pectin and polypheno loxidase activity were evaluated. Lower shelf life was observed for control treatment (31 d) and largest was found at 15, 20 and 25 ºC (45 d). A sligthly delay was observed in the breathing pick at 15, 20 and 25 ºC at 25 d and not in the 20 d as observed in the other treatments. Soluble solids increased with storage time for all of temperature treatment, but at 15, 20 and 25 ºC increase was smaller. Texture an C vitamin were higher in fruits stored at 25 ºC. Soluble pectin was smaller at the end of storage period, at temperatures of 20 and 25 ºC. Polyphenoloxidase activity decreased along 30 d regardless storage temperature. Treatments at 20 and 25 ºC were the most effective for mainteining posthaverst quality of the jabuticaba fruits.

Este trabalho teve como objetivo estudar o efeito combinado da desidratação osmótica e a influência do cloreto de cálcio em rodelas de kiwi submetidas ao processamento mínimo. Amostras com e sem desidratação osmótica foram armazenadas a 5 °C em embalagem PET. A adição do cloreto de cálcio foi realizada durante a desidratação osmótica. Foram avaliados a perda de peso, acidez, sólidos solúveis, pH, umidade, coliformes, fungos e leveduras nas amostras até 15 dias de armazenamento. A avaliação microbiológica e sensorial definiu a vida de prateleira do produto. Os resultados mostraram que o pré-tratamento osmótico com adição de cloreto de cálcio aumentou a vida útil em até 15 dias, enquanto as rodelas tratadas por osmodesidratação, sem a adição do sal apresentaram vida útil de 12 dias. Sensorialmente, os consumidores preferiram as rodelas de kiwi processadas com pré-tratamento osmótico e adição de cloreto de cálcio.

Este trabajo tubo como objetivo estudiar el efecto combinado de la deshidratación osmótica y la influencia del cloruro de calcio en rodajas de kivi sometidos al proceso mínimo. Muestras con y sin deshidratación osmótica fueron almacenadas a 5 °C en embalajes PET. La adición de cloruro de calcio fue realizada durante la deshidratación osmótica. Se evaluaron la pérdida de peso, acidez, sólidos solubles, pH, humedad, coliformes, hongos y levaduras en las muestras hasta 15 días de almacenamiento. La deshidratación osmótica consistió en la inmersión de las rodajas de kivi en solución de sacarosa a 60% y en solución de sacarosa (60%) con adición de cloruro de calcio (0,1 M), ambos tratamientos se realizaron a temperatura ambiente (25 °C) por 24 horas y relación fruta:solución de 1:5. Los resultados mostraron que el pré-tratamiento osmótico con adición de cloruro de calcio aumentó la vida útil hasta 15 días, en cuanto las rodajas tratadas por osmodeshidratación sin adición de sal presentaron vida útil de 12 días. Sensorialmente, los consumidores prefirieron las rodajas de kivi procesadas con pré-tratamiento osmótico y adición de cloruro de calcio.
