Desenvolvimento de produtos artesanais em bambu e em bambu laminado colado e a transferencia desse conhecimentopara a comunidade do Assentamento Rural Horto de Aimorés

Introdução: O bambu é uma cultura perene, renovável, de rápido crescimento, com produção anual de colmos e com milhares de possibilidades de uso. O Assentamento Rural Horto de Aimorés, distante 15 km da UNESP, possui cerca de 350 famílias assentadas pelo INCRA, desde o ano de 2007, e a comunidade, que tem por característica básica o trabalho com a terra, vem buscando alternativas de sustentabilidade, fixação ao campo e geração de renda. Este trabalho faz parte do projeto de extensão “Implantação do Projeto Bambu no Assentamento Rural Horto de Aimorés”, Unesp – Unisol / Banco Real - Santander, desenvolvido no Laboratório de Experimentação com Bambu da Unesp, campus de Bauru. O projeto de extensão universitária prevê um conjunto de atividades de capacitação e desenvolvimento pautadas em estudos na área da sustentabilidade e do design de modo a dar condições técnicas para geração de renda. Objetivos: O objetivo deste trabalho foi o desenvolvimento de três produtos artesanais em bambu, pulseira, pegador de pimenta e pote de aperitivos, capazes de gerar renda. Depois de desenvolvidos pelos agricultores, os produtos são periodicamente expostos ao público através da participação em feiras e mostras locais na cidade, como por exemplo, feira Ubá e feira do grupo Pão de Açúcar. Métodos: Este trabalho ocorreu em três etapas, a primeira envolvendo a colheita e processamento do bambu. A segunda através de oficinas de extensão com os agricultores, para a confecção dos produtos artesanais em bambu in natura. A terceira envolvendo a geração de renda com os agricultores através de participações em amostras e feiras locais. Resultados: As oficinas ocorreram de forma prática e permitiu aos agricultores o aprendizado de todo o processo para a confecção do produto final. A confecção dos produtos artesanais tem mostrado a viabilidade técnica da utilização do bambu como matéria prima e a capacitação e evolução mostrada pelos agricultores permitem que se desenvolvam novos produtos, num processo gradual e contínuo de aprendizado e geração de renda.

Avaliação de monitorias realizadas em um centro de ciências

In this paper we investigate the social interaction established between monitors and student-visitors to a science museum in terms of knowledge mobilized by the explanation about principle operating of Van De Graff Generator. Our research was conducted at a university public that maintains a Center of Sciences and the data were collected through recording video and audio of the dialogues established around a demonstration experiment. Data analysis is established around the conceptual correctness of the explanations made by the monitors. We also conducted a structured interview from a single question: what is the main difficulty faced in planning and conducting his presentation at the Science Center? The results show that the monitors were not able to exceed the process description of the operation of the experimental equipment, not being able to establish an interaction that fosters discussions of scientific concepts with visitors. Our research also found that, although the university maintained a Sciences Center, not there is a link between teacher training and activities in non-formal settings.

The Caracara genus (Aves: Falconidae) is composed by species C. cheriway, ("Crested Caracara"), and C. plancus (Southern Caracara). This study aimed to describe in detail and compared the cranial osteology of C. cheriway and C. plancus, identifying osteological cranial characters for a future systematic work. The two common characters of Caracara species are: the projection of rostro parasphenoid reaches 50% of the distance from the occipital condyle to the pterygoid; the upper maxilla has about 4/9 of the total length of theskull, the symphysial portion of mandible occupies about 1/7 of its total length, the proximal portion of lacrimal bone ends in a rounded shape and has about 1/4 of the width of the distal portion. The unique characters of C. cheriway are: the interorbital width is about 1/2 of the parietal region, shows a frontal bone prominence; presence of lacrimal process of frontal bone; the proximal portion of the lacrimal bone reaches 1/5 of the distance from the orbital arc to the jugal bone; the distance between the distal portions of two lacrimal bones reach 5/6 of the parietal width, the ratio between the interorbital diameter and parietal region ranges from 2 times; the zygomatic process occupies about 40% of the distance between its origin in the skull and jugal bone. The unique characters of C. plancus are: the interorbital width is approximately 4/7 of the parietal width; show a rostral medial concavity; the proximal portion of the lacrimal bone is about 1/4 of the width of the distal; the proximal portion of the lacrimal bone reaches 1/7 of the distance from the orbital arc to the jugal bone; the distance between the distal portions of two lacrimal bones reaches 6/7 of the width parietal one; the ratio between the interorbital diameter and parietal region varies 1, 75 times, the zygomatic process occupies about 35% of the distance between its origin in the skull and jugal bone.

Assessment of the risk of raw milk consumption related to staphylococcal food poisoning

This study aimed to identify the risks of staphylococcal food poisoning due to the consumption of raw milk. Fifty-one farms in Londrina (PR) and 50 in Pelotas (RS) were analyzed, to determine the population of coagulase-positive staphylococci (UFC/ mL), as well as to verify the ability of producing Staphylococcal Enterotoxin A (SEA) by immunodifusion (OSP), the presence of the gene for the production of SEA (PCR) in the cultures, and the research of enterotoxin (SEA to SEE) in milk samples using ELISA commercial kit. Considering the 101 farms analyzed, 19 (18.8%) presented coagulase-positive staphylococci count above 105 UFC/mL. For the evaluation of the enterotoxigenic ability (SEA) by the OSP technique, six cultures coagulase-positive (5.5%) were positive to the test and identified as S. aureus. From the coagualse-negative sample, one (5.5%) was OSP positive. For the evaluation of the presence of the gene for EEA synthesis, 51 cultures of staphylococci were tested. From this total, 14 (27.45%) presented the gene, and from that, only 5 (9.81%) cultures were capable of expressing it in the technique of the OSP. The morphologic characteristic of the evaluated cultures that had enterotoxigenic capacity, from the 14 (33,3%) cultures that presented the gene for EEA production, 05 (11.9%) were characterized as typical cultures of S.aureus in Baird Parker agar. All the 12 milk samples studied for the presence of EEA to EEE in milk were negative. Thus, it can be concluded that there is extensive contamination of raw milk for staphylococci coagulase, however, most of the isolated strains were not enterotoxigenic or did not express such a characteristic. Only 9.81% of the tested colonies expressed the gene and effectively produced SEA. None of the samples had sufficient counts to produce detectable amounts of SEA. The milk samples did not present risk to cause staphylococcal food poisoning if consumed in natura until the collection moment.

Caracterização química e legalidade em bebidas não alcoólicas de maçã

Apple is a fruit that offers promising prospect for industrialization as it has favorable characteristics for this purpose and can obtain products with good acceptance. In Brazil, approximately 15% of the production is processed into juice, and a portion is exported. Among the fresh fruit and juice, apple adds US$ 30 million annually to the Brazilian foreign exchange earnings. The aim of this study was to characterize, using chemical analysis, concentrated juices, commercial apple juice, nectar, and soft drink. In addition, to compare them with their respective Quality and Identity Standards (PIQ) published by the Ministry of Agriculture, Livestock and Food Supply (MAPA) and Codex Alimentarius. Concentrated juices and commercial beverages were analyzed in triplicate for soluble solids content (Brix), pH, total acidity (AT), and ratio. In concentrated juices, the Total Sugar Reducer (ART) was also assessed. The results obtained in the laboratory were compared with the PIQ and Codex Alimentarius to verify compliance with applicable regulations. Seven concentrate juices, five juices, six nectars, and three apple-flavoured soft drinks were analyzed. The Brix of pulpy and clarified concentrated juices were, respectively, 71.16±1.29 and 40.40±0.57°Brix. In all concentrated juices, the Brix was in accordance with Codex Alimentarius. The Brix and AT in sweetened clarified juices were 11.50±0.14°Brix and 0.18±0.04g of malic acid/100g sample. In pulpy whole juices the values ​​were 11.20±0.70°Brix and 0.30±0.06g of malic acid/100g sample. The values of Brix and AT in apple-flavoured soft drinks were 11.03±0.93°Brix and 0.18±0.04g of malic acid/100ml sample. Commercial juices and soft drinks also presented °Brix and AT in accord with the PIQ established by MAPA. The apple nectars could not be compared with the standards because they are not published by MAPA or Codex Alimentarius. The definition of the PIQ is an important tool for quality control of beverages manufacture in Brazil. Therefore, it is recommended for the control agencies to define the parameters that are not established.

Processamento da amostra das silagens de grãos úmidos de sorgo com baixo e alto tanino na determinação da digestibilidade aparente em equinos

There were used four castrated male horses, crossbred. It was used randomized block by design for four replications. The objective was to evaluate the effect of using samples, ground or in natura, in the precision of the mobile nylon bag technique (MNBT) in comparison to the total collection (CT) method in oder to estimate the apparent digestibility coefficient (DC) of nutrients of high-moisture grains silage of sorghum with low (SSLT) and high (SSHT) tannin in the feeding equine. No effect was observed for MNBT and CT methods with in natura sample for DC of DM, OM, CE, CP to SSLT (P>0.05), whose average values were 81.71, 84.23, 82.27 e 81.43%, respectively. The MNBT did not showacuracy to evaluate of DC of the SSHT, with ground and in natura samples. It was concluded that MNBT containing in natura sample should be used to determinating the DC of SSLT to DM, OM, CE and CP for equines.

Determinação do teor de glicose em bagaço de cana-de-açúcar hidrolizado pelo processo de conversão enzimática

The production of ethanol and sugar from sugarcane juice generate as byproduct, the bagasse. Currently, the bagasse, an industrial lignocellulosic biomass, can be used for production of second-generation ethanol, since when it is submitted to hydrolytic processes generates fermentable sugars. The objective of this study was to produce fungal enzymes capable of hydrolyzing this lignocellulosic biomass to generate glucose. For this, we used the mushroom species Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, and Pycnoporus sanguineus as potential sources of laccase, manganese peroxidase and lignin peroxidase enzymes, capable of hydrolyzing the crushed sugarcane. The hydrolysis process was performed with the highest enzymatic activities observed from laccase in L. edodes (39.23 U-mL after 25 day incubation), P. ostreatus (2.5 U U-mL after 27 day incubation), P. sanguineus (80 U-mL after 27 days of incubation) and P. eryngii (16.45 U-mL 15 days incubation). MnP and LiP showed no significant results. The enzymatic hydrolysis of sugarcane bagasse in natura (32,17% hemicellulose, cellulose 52,45% and 10,62% lignin) and bagasse hydrolyzate with 7,0% H2SO4 (0,20% hemicellulose, 68,82% to 25,33% cellulose and lignin) were evaluated for each enzymatic obtained. Compared to others, the enzymes produced by P. sanguineus incubated in sugarcane bagasse showed better efficiency resulting in glucose with an average content of 0,14 g-L. Although the levels of glucose determined in this work were low in relation to the literature, it can be stated that the laccase, manganese peroxidase and lignin peroxidase enzymes demonstrated good hydrolytic potential, especially those produced by the fungus P. sanguineus.

Base genética do hábito de crescimento e florescimento em tomateiro e sua importânciana agricultura

Hybrids or open pollinated tomato cultivars used for sauces and ketchups production usually has determinate growth habit, while most of the genotypes used in the production to salads (in natura consumption) has indeterminate growth habit. Additionally, growth habit can have influence on culture management, productivity and total soluble solids (TSS) in fruits. The growth habit is mainly controlled by the gene SELF-PRUNING (SP), which is a component of a small gene family which is also part of the gene SINGLE FLOWER TRUSS (SFT), currently considered one of the components so sought after 'florigin'. Understanding the biochemical function and physiological effect of such genes in interaction with the environment and other genes (epistasis), allows the manipulation of parameters such as precocity and TSS. It also provides subsidies to understand the genetic basis of semideterminate growth, which combines the advantages of determinate and indeterminate habit and can be used for plant breeders to development of new cultivars.

CHARACTERIZATION STUDY OF CAMBUCI FRUIT [Campomanesia phaea (O. Berg.) Landrum] AND ITS APPLICATION IN JELLY PROCESSING

CHARACTERIZATION STUDY OF CAMBUCI FRUIT [Campomanesia phaea (O. Berg.) Landrum] AND ITS APPLICATION IN JELLY PROCESSING The objective of this paper was to study possible differences of varieties of cambuci fruit reported by producers by means of fruit characterization and elaboration of jelly. The fruits were divided in four possible varieties groups, named as A, B, C and D, and submitted to analysis regarding weight, ash, moisture, pH, soluble solids, acidity, ratio, ascorbic acid and water activity. To the preparation of the jelly was chosen the variety A with two formulations, 50%50% and 40%60%, fruit and sugar respectively. Concerning the possible varieties of cambuci only water activity was not significantly different. The acidity and ratio of B variety are noteworthy, because it did differ from the others presenting a more satisfactory result for in natura consumption. All other tests presented statistic alteration of at least one variety, but since these data can be influenced by edaphoclimatic conditions they must be carefully observed. Lower results for pH, acidity, luminosity and degrees hue, were observed for the 60% sugar jelly sample, which contributed for its better results in the preference test for the attributes appearance, color, flavor and texture. The evaluation of attribute aroma of both samples (50% and 60%) did not differ.
