Refrigerated storage of pitombas subjected to different packaging

This study aimed to verify the effect of the association between refrigeration and packaging on the preservation of postharvest quality of pitombas during storage. The fruits were harvested, transported to the laboratory, where they were selected, washed with neutral detergent and drinking water, and left to dry. Subsequently, the fruits packed in polypropylene (PP), low-density polyethylene (LDPE), polyethylene terephthalate (PET), polyvinyl chloride (PVC) + expanded polystyrene (EPS), and no packaging (Control). After this process, they were stored at temperatures of 6, 8, 10, 12, and 14±1 °C at 75±5% relative humidity (RH). The fruits were evaluated during 12 days for postharvest preservation, firmness, soluble solids content, pH, hue angle and chroma of the peel, with three replications of 10 fruits each, using a completely randomized design in a 5 × 5 × 7 factorial scheme (5 temperatures × 5 packages × 7 days of analysis). The results were subjected to analysis of variance (P≤0.05) and, when significant, the means were compared using the Scott-Knott test and regression at a 5% significance level. The use of LDPE packaging associated with refrigeration at 6 °C can be used to store pitombas for 12 days, as these conditions preserved the evaluated parameters, guaranteeing fruit quality.This study aimed to verify the effect of the association between refrigeration and packaging on the preservation of postharvest quality of pitombas during storage.

The use of controlled atmosphere with low level of oxygen maintains the quality of guava fruit (Psidium guajaba l. cv. ‘Pedro Sato’) during cold storage

POR] O efeito da atmosfera de armazenamento com diferentes concentrações de oxigênio (controle, 20%, 15%, 10%, 5% e 1%) foi investigado durante o armazenamento refrigerado de goiabas ‘Pedro Sato’. As atmosferas com as menores concentrações de O2 (5% e 1%) reduziram significativamente a taxa respiratória o que resultou no retardamento do proceso de amadurecimento, o que foi confirmado pela manutenção da coloração mais verde (°h), maiores teores de açúcares solúveis totais e redutores, bem como, menor solubilização dos compostos pécticos. Os frutos controle e os armazenados nas maiores concentrações de oxigênio (20% e 15%) apresentaram pico climatérico no 16o e 20o, respectivamente. Entretanto, este não foi observado para os mantidos nas atmosferas contendo 10%, 5% e 1%. Além dos aspectos fisiológicos, as atmosferas com as menores concentrações de O2 (5% e 1%) reduziram o desenvolvimento de podridões o que resultou na manutenção da aparência de conseqüentemente da qualidade final do produto após 28 dias de armazenamento a 12,5°C. [ENG] The effect of storage atmospheres containing different oxygen levels (control, 20%, 15%, 10%, 5% e 1%) was investigated during the cold storage of ‘Pedro Sato’ guava. Atmospheres with the lowest O2 concentrations (5% and 1%) significantly reduced the respiratory rates which delayed the ripening process, which was confirmed by the maintenance of greener colour (°h), higher total soluble and reducing sugar contends, as well as, lower pectic compound solubilization. Control fruit and those stored at the highest oxygen concentration (20% and 15%) presented climateric pick at the 16th and 20th day, respectively. It was not observed for fruit maintained at atmospheres containing 10%, 5% and 1%, although. Despite the physiological aspects, the atmospheres with the lowest O2 concentrations (5% and 1%) reduced rot development leading better appearance maintenance and consequently better final product quality after 28 days of storage at 12.5°C.Os autores gostariam de agradecer a Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) pela concessão da bolsa de pós-doutorado (Proc. no 05/56160-0) e do auxílio à pesquisa (Proc. no 05/56159-1)

PASO -- Astronomy and Space Situational Awareness in a Dark Sky Destination

The Pampilhosa da Serra Space Observatory (PASO) is located in the center of the continental Portuguese territory, in the heart of a certified Dark Sky destination by the Starlight Foundation (Aldeias do Xisto) and has been an instrumental asset to advance science, education and astrotourism certifications. PASO hosts astronomy and Space Situational Awareness (SSA) activities including a node of the Portuguese Space Surveillance \& Tracking (SST) infrastructure network, such as a space radar currently in test phase using GEM radiotelescope, a double Wide Field of View Telescope system, a EUSST optical sensor telescope. These instruments allow surveillance of satellite and space debris in LEO, MEO and GEO orbits. The WFOV telescope offers spectroscopy capabilities enabling light curve analysis and cosmic sources monitoring. Instruments for Space Weather are being considered for installation to monitor solar activities and expand the range of SSA services.Comment: 9 pages, 2 figures, Keywords: Dark Sky, radioastronomy, space, space debris, space situational awareness; Draft from Talk presented at Astronomy and Satellite Constellations: Pathways Forward, IAU Symposium 385, October 2023, Ed.

Neurofeedback como opção terapêutica no manejo da fibromialgia / Neurofeedback as a therapeutic option in the management of fibromyalgia

A fibromialgia é uma síndrome de dor musculoesquelética comum, crônica, muitas vezes debilitante, que envolve dor generalizada em pontos específicos, e muitas vezes é acompanhada de fadiga, sono desordenado, queixas cognitivas e uma série de outras queixas somáticas, bem como sofrimento psíquico. No cenário de tratamentos surge o neurofeedback, que ensina os indivíduos a autorregularem suas ondas cerebrais e intervém no nível do sistema nervoso central. O objetivo desse trabalho visa avaliar a utilização do neurofeedback como opção terapêutica no manejo da fibromialgia, a fim de buscar estratégias mais eficazes para o tratamento dessa dor crônica, bem como minimizar os impactos negativos na qualidade de vida dos pacientes acometidas. Esse estudo trata-se de um artigo do tipo revisão sistemática, com artigos publicados nos últimos 10 anos. Utilizou-se os bancos de dado PubMed e a Biblioteca Virtual em Saúde com os descritores “Neurofeedback AND Fibromyalgia”. Vários estudos foram feitos em busca de melhoras na qualidade de vida dos pacientes que sofrem com fibromialgia, buscando uma alternativa através de modulação ou condicionamento por neurofeedback. Encontrou-se não uma forma de curar a doença ou dar fim aos seus sintomas, mas de atenuá-los consideravelmente. Conclui-se que a utilização do condicionamento/modulação por neurofeedback é significativamente efetiva na diminuição dos sintomas apresentados pelos pacientes, proporcionando assim, uma melhoria em sua qualidade de vida

Innovation of Textiles through Natural By-Products and Wastes

Nowadays, the competitiveness of the textile industry and the consumers’ interest have been increasing the demand for innovative and functional textiles. Allied to this, sustainable developments are playing an increasingly important role in the textile industry. Such concerns led to a new development strategy based on the valorization of bio-based wastes and by-products of different industries, inserting this in the circular economy paradigm. These bio-based wastes and by-products come from several industries, as the agri-food industry. These resources present an enormous potential for valorization in the textile finish due to their intrinsic properties (antimicrobial, prebiotic, antioxidant activity, among others). This chapter will review the latest innovation and textile product development through different by-products and wastes, their main properties and characteristics and the advantages that they offer to the textile industry

Evaluation Process: Elaboration of the Individual Educational Program

Inclusive education recommends access to quality education for all, allowing the appropriation of knowledge and the development of skills, guiding individuals according to responses adapted to social demands. The public school is the guarantor of quality responses to the socio-cultural, physical or mental diversity of the individual. The objective of this study is to meet what is suggested by the national and international directives for an inclusive school, and intends to analyze the evaluation process that the multidisciplinary teams elect for the design of the Individual Educational Program (PEI). Data collection will be done through questionnaires and interviews with multidisciplinary special education teams from 3 school groups. The preliminary results point out that although all are based on dec-Law 3/2008, each grouping is organized in its own way, and there is no uniformity in the processes

The role of Trichoderma reesei cellulases in cotton finishing

Knitted and woven cotton fabrics were treated with a mono component Trichoderma reesei endoglucanase (EGII) and with experimental Trichoderma cellulase mixtures containing different cellulase profiles. The cellulase action was evaluated by measuring weight loss, pilling, and bursting strength. Of the experimental mixtures, Cellulase F, being an EGII-enriched preparation, was the best mixture to obtain the highest pilling reduction with the lowest strength and weight losses on cotton knitted fabric. The monocomponent EGII was, however, even more efficient with respect to good depilling with minimal negative effect on the knitted fabric. The results obtained with the different cellulases were found to depend on the fabric type. In the case of ring-spun woven fabric, purified EGII was the best enzyme in depilling with the lowest weight loss. Cellulase B (containing CBHI and EGII) reduced the pilling tendency, but the weight loss was higher as compared to that obtained with the monocomponent EGII. In the case of open end-spun woven fabric, Cellulase B and Cellulase E (EGII enriched, CBHI negative) resulted in improved depilling, but at the same time they caused relatively high weight loss
