Real cockpit proposal for flight simulation with airbus A32x models: an overview description

This paper describes the several steps to build an elaborate flight simulator cockpit, where the hardware is designed based on Mechatronic principles and the proposed software was developed using agile methodologies to create a Cyber-Physical System (CPS). Furthermore, this research attempts to simulate the real environment from an aircraft as close as possible with a real scale developed cockpit. Based on this, the presented paper contributions include: (1) The implementation of a complex dynamic system such as a CPS, where the Mechatronic system is part of it; (2) The deployment of a scale model of an Airbus A32x aircraft (one of the most used), integrating into a mathematical model adapted to the operation of an aircraft flight simulation system, regarding the physical forces involved. This project is also used to captivate the students’ motivation to the areas of technology such as electronics and programming and permits its development as a student project and thesis. Results allow validating the proposed cockpit.This work has been supported by FCT - Fundação para a Ciência e Tecnologia within the Project Scope: UIDB/05757/2020.info:eu-repo/semantics/publishedVersio

INITIAL DEVELOPMENT OF EUCALYPTUS CLONE I144 (Eucalyptus grandis x Eucalyptus urophylla) IN RESPONSE TO FOLIAR AND SOIL FERTILIZATION

The nutritional management of eucalyptus (Eucalyptus spp.) is one of the main factors responsible for the success of its cultivation. We aimed to evaluate the initial growth and nutritional status of eucalyptus clone I144 (Eucalyptus grandis x Eucalyptus urophylla) submitted to foliar fertilizers application containing boron-B, iron-Fe and bio-stimulant and via soil application of nitrogen-N and phosphorus-P doses. The experiment has been conducted in a rural private property of Tamarana, Parana (PR) in a subdivided plots experiment design with four replications (n=4). The plots treatments were boron, boron+iron, boron+iron+bio-stimulant applications under algae (Ecklonia maxima) presence and a control (water). The subplots treatments were composed by the application of 100, 150 and 250 g plant-1 rates of 10-20-00 (N-P2O5-K2O) and a control (0 g plant-1 of 10-20-00). It was evaluated the height and diameters of plants at 45, 78, 117, 150 and 235 days after planting (DAP) and the leaves nutrient content (N, potassium-K, calcium-Ca, magnesium-Mg, sulfur-S, copper-Cu, zinc-Zn, manganese-Mn and Fe) at the end of the cultivation. The fertilization via soil did not interfere on either growth or macronutrients contents. On the other hand, the combined application of foliar fertilizers has increased the macronutrients contents without interfering on growth parameters

ITASAT-2 Mission Overview

The ITASAT-2 project is part of a progressive development of CubeSat space missions at the Instituto Tecnológico de Aeronáutica (ITA). Focused simultaneously on space weather and on the development of new technological solutions, the ITASAT-2 mission is based on the previous developments of the ITASAT-1 and SPORT missions. Consisting of three 12U CubeSats in a formation flight, the mission expands on the study of ionospheric plasma movements and density, small-scale ionospheric structures, magnetic field, and radiation environment. On the development of technological solutions, the mission proposes to test a baseline option at LEO to understand the influence of ionospheric phenomena and signal deterioration on geolocation/aviation-related services. While it allows for the development of support technologies closely related to airworthiness and flight safety, the formation flight arrangement is expected to provide novel (temporal) insights on the evolution of ionospheric events. This paper presents an overview of the ITASAT-2 mission with the main mission objectives, the concept of operation, initial Systems Engineering analysis, and expected work for the next phases of the project

Análise semiótica das capas da Revista Secretária Executiva do ano 2000

As capas de revistas funcionam como uma vitrine para atrair público. Com a evolução da profissão de secretária (o) notou-se a utilização e a evolução dos recursos semióticos nas capas de revistas direcionados para a categoria secretarial, por isso, torna-se importante compreender como esta (e) profissional era representada (o) em determinada época. Diante disso, este trabalho teve como objetivo compreender como a (o) profissional de Secretariado era representada (o) nas capas da revista Secretária Executiva à luz da semiótica. Em relação aos procedimentos metodológicos, este estudo se caracterizou como descritivo, qualitativo, tendo como amostra 12 capas de revistas do ano 2000. Os resultados encontrados mostram a exclusão do homem no ofício, a falta de representatividade de pessoas negras, gordas, de idade madura e a utilização de manchetes com duplo sentido. Por fim, conclui-se que a questão da estética, do gênero e da sensualização da (o) profissional era reproduzido constantemente, fomentando o estereótipo da profissão. ABSTRACT The covers of a magazine act as a showcase with the objective of attracting the public. With the evolution of the profile of the profession, covers started to use semiotic resources directed to the secretarial category, so it is important to understand how this professional was represented the 2000s. The secretarial professional was represented on the covers of a specific magazine for this category in the 2000s in the light of semiotics. Regarding the methodological procedures, this study is characterized as descriptive, with a qualitative approach, having as a sample 12 magazines from the year 2000. The results showed the exclusion of men, the lack of representation of black, fat, and older secretaries, and the use of headlines with double meanings. Finally, from the results found, we can conclude that the issue of aesthetics, gender and sensuality of the professional was constantly reproduced, promoting the stereotype that the profession is considered feminine.

Engineering Challenges of a CubeSat Mission Around the Moon: First Steps on the Path to SelenITA

Flying beyond Earth\u27s sphere of influence has been part of the main goals in space exploration. Efforts of the Artemis program now encompass different classes of missions, including CubeSats. With the challenges of deep space as mission drivers, planning, designing, launching, and operating a CubeSat for a Moon mission is proving to be a step up in difficulty. In this context, SelenITA Mission is conceived as a science mission supporting the Artemis efforts, planned to operate at Low-Lunar Orbit (LLO), flying below 200 km gathering space weather and geophysics observations, marking the first Brazilian mission to the Moon. This paper outlines the engineering challenges encountered this far in the development of SelenITA. It presents the aspects of lunar orbits and the effects of Moon\u27s potential field on a 12U CubeSat in LLO. A Reference Scenario is established, followed by an exploration of the extreme lunar environment\u27s effect on the satellite\u27s thermal, radiation, and power aspects. Communication limitations in the cislunar environment are analyzed, and strategies for the Attitude and Orbit Control Subsystem are discussed. The paper also addresses the challenges associated with delivery, uncertainties, and supply chain. A conceptual overview of the system is presented, concluding with the future steps

Production optimization of biodiesel from frying oil waste to reduce the environmental impacts

The objective of this study was to reduce the environmental impacts of used frying oil waste through the production of biodiesel. A 22 factorial planning has been used to evaluate the influences of alcohol/oil and reaction time on the biodiesel production yield. The optimal condition to produce the biodiesel has been found by use of the response surface methodology and analysis of variance to obtain the fitting model. This study was conducted in Campinas city, Brazil, where were collected the waste oil. An analysis of ecological cost also has been developed. Cooking oils collected from Campinas homes were mixed with ethanol in planned proportions (1:9, 1:7 and 1:5) and were transesterified at 60 °C and planned reaction times (30, 60 or 90 min), in order to obtain biodiesel, using 0.1% NaOH as a catalyst. The results of the physical-chemical analyses demonstrated that the biodiesels obtained possessed characteristics close to those required by Brazilian standards. This fuel could be used in fleets of buses, trucks and machines, or even sold to fuel distributors, which results in a solving between US$0.8 and US$4.5 millions. Thus, Campinas would gain environmental credits and become a sustainable city8621625CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQsem informaçãoThe authors thank to Nine July University (UNINOVE) and National Research Council CNPq for the financial support

Lessons Learned During Testing Through Commissioning of the Joint Brazil-US SPORT Mission

SPORT is an international partnership mission between Brazil and the United States to study ionospheric space weather processes that occur at low latitudes. Operating a CubeSat on orbit is certainly one of the most exciting milestones of a CubeSat project, but it is only a part of the mission. To be able to achieve this milestone the efforts of the engineering team were focused late in the project on the integration, testing, and delivery followed by the on-orbit commissioning of the observatory. This paper details the major events and lessons learned by the SPORT team during these phases of the project. SPORT experienced a failure of the battery subsystem during environmental testing followed by physical damage during shipping from Brazil to the United States for Launch. However, more than pointing out these problems, solutions, and lessons learned, this paper explains how the international team worked to overcome the issues and finalize the observatory for delivery and launch. After release from the ISS the SPORT team looked forward to the on-orbit observatory operations, first contacts, and the commissioning phase of the observatory, that is also described on this paper

Sensory acceptance and physico-chemical composition of mixed minas frescal cheese

Buffalo milk presents higher proteins and lipids concentration than cow milk, which provides a better yield in cheese-making production and products with considerable sensory approval. However, buffalo milk is not regularly available throughout the year due to different handling conditions. Thus, to guarantee the supply of buffalo milk dairy products during the year, the addition of bovine milk is an alternative. Therefore, this study aimed to test the effect of a buffalo and bovine milk mixture for the Minas Frescal cheese elaboration by physico-chemical, sensory analysis and obtaining yield. The raw material was analysed for the parameters of acidity, density, fat, total solids and solid-not-fat. There were 3 Minas Frescal cheeses elaborated from 3 formulations: 100% buffalo milk, 100% bovine milk and the mixture of 50% of each milk. The cheeses were submitted to the Gravimetric and Gerber methods to obtain values of moisture and fat, as well as to obtain, indirectly, fat in dry matter. For bovine and buffalo milk, the parameters evaluated (acidity, density, fat, total solids and solids-not-fat) complied with Brazilian legislation and parameters described in the literature. For the bovine, mixed and buffalo fresh cheeses, values were obtained, respectively, for moisture (74.04, 60.93 and 63.61), fat in dry matter (44.35, 42.23 and 46.03) and cheese yield (27, 20.8 and 24.2), indicating a higher yield for the bovine Minas Frescal cheese and higher fat content for the buffalo cheese. The overall acceptance of the mixed Minas Frescal cheese was significantly superior to the bovine and buffalo cheese. The parameters of colour, appearance, texture, flavour and overall acceptance were above 8 points in the hedonic scale (‘moderately liked’ to ‘extremely liked’), and the aroma attribute scored was above 7 (‘I enjoyed regularly’ to ‘moderately liked’). Therefore, the elaboration of Minas Frescal cheese from the mixture of 2 matrices (buffalo and bovine milk) demonstrated technological viability with the potential to meet the demands of the consumer market

Kinin B1 receptor deficiency protects mice fed by cafeteria diet from abnormal glucose homeostasis

The kallikrein–kinin system has been implicated in body weight and glucose homeostasis. Their major effectors act by binding to the kinin B2 and B1 receptors. It was assessed the role of the kinin B1 receptor in weight and glucose homeostasis in B1 receptor knockout mice (B1RKO) subjected to a cafeteria diet (CAF). Wild-type (WT) and B1RKO male mice (C57BL/6 background; 8 weeks old) were fed a standard diet (SD) or CAF for 14 weeks, ad libitum, and four groups were formed: WT-SD; B1RKO-SD; WT-CAF; B1RKO-CAF. Body weight and food intake were assessed weekly. It was performed glucose tolerance (GTT) and insulin tolerance tests (ITT), and HOMA-IR, HOMA-β and HOMA-β* 1/HOMA-IR were calculated. Islets from WT and B1RKO were isolated in order to measure the insulin secretion. Western blot was used to assess the hepatic AKT phosphorylation and qPCR to assess gene expression. CAF induced a higher body mass gain in B1RKO compared to WT mice. CAF diet increased epididymal fat depot mass, hepatic fat infiltration and hepatic AKT phosphorylation in both genotypes. However, B1RKO mice presented lower glycemic response during GTT when fed with CAF, and a lower glucose decrease in the ITT. This higher resistance was overcomed with higher insulin secretion when stimulated by high glucose, resulting in higher glucose uptake in the GTT when submitted to CAF, despite lower insulin sensitivity. Islets from B1RKO delivered 4 times more insulin in 3-month-old mice than islets from WT. The higher insulin disposition index and high insulin delivery of B1RKO can explain the decreased glucose excursion during GTT. In conclusion, CAF increased the β-cell function in B1RKO mice, compensated by the diet-induced insulin resistance and resulting in a healthier glycemic response despite the higher weight gain
