The objective of this work was to evaluate the production costs and profitability indexes of sorghum crop for silage production under different irrigation depths. The work was conducted at the Federal Institute of Education, Science and Technology of Ceará (IFCE) – Umirim Campus, from September to December 2016. The treatments were arranged in 5 x 5 split plots with 5 replications. Irrigations were performed on a daily basis, and the applied depths were calculated based on crop evapotranspiration (ETc). The primary treatments were 50, 75, 100, 125 and 150% of ETc, associated with different levels of carnauba bagana mulch (0.00, 2.50, 3.75, 5.00, and 6.25 cm). Effective Operating Cost (EOC), Total Operating Cost (TOC), Gross Revenue (GR), Operating Profit (OP), Profitability Index (PI) and Break-Even Price (BEP) were estimated. According to the indicators analyzed, it was found that this is a promising crop within the different agricultural production schools, with favorable rates for the producer. The variety evaluated presents high resistance as to the water limitation factor, showing positive indicators such as break-even point below the average prices practiced in the region.

Corn is a widely used crop for silage. However, due to the changes introduced in recent genotypes, regional information related to the agronomic production behavior and the chemical composition of the silage produced becomes necessary for the appropriate technological development destined to agricultural and animal production in the Amazon region. With this premise, the present study aimed to evaluate the agronomic performance of corn hybrids cultivated for silage production and the chemical composition of the ensiled material. The experiment was conducted from October 2020 to March 2021, under field conditions, in the experimental area of the Federal Institute of Education, Science and Technology of Rondonia, Colorado do Oeste Campus, in the municipality of Colorado do Oeste, RO, Brazil. The experimental design used was completely randomized, composed of six corn hybrids (GNZ7210 VTPRO2, AG8480 VTPRO3, BM3073 VTPRO3, BM270 VTPRO2, BM3066 VTPRO3 and BM3077 VTPRO3) and five replicates, cultivated at spacing of 0.80m between rows and 0.20m between plants. There was variation in the agronomic performance of the commercial corn hybrids for the southern region of Rondônia. The silages produced from the six corn hybrids showed bromatological and chemical characteristics that characterize them as silages of very good quality, despite showing significant differences in the percentages of DM, MM, CP, N-NH3/TN, NDF and ADF. The hybrid BM3073 PRO3 stood out for fresh matter yield, shoot N content and quality of the silage produced, which may result in the reduction of silage production costs.

Crop rotation is one of the pillars of conservation agriculture. This practice has offered a series of advantages in terms of improving soil physical, chemical, and biological conditions. These advantages result in yield increases for all economic crops involved in the rotation systems and may also reduce production costs. In this context, the aim of this study was to compare the profitability of crop rotation systems with different levels of crop diversification. The experimental design was randomized blocks, with five treatments and four replications. The treatments included one less diversified crop rotation system (control) with soybean and wheat and four more diversified crop rotation systems (involving three or more species), including soybean, wheat, black oats, maize, canola, barley, blue lupine, white oats, beans, radish, triticale, rye, hairy vetch, and sorghum, under no-tillage conducted during a three-year cycle. Analyses were conducted considering productivity, operating cost, and economic profit. The highest accumulated gross yields were obtained in the more diversified crop rotation systems. The results show that the more diversified crop rotation systems were more profitable. When the opportunity cost was included, the most diversified crop rotations presented greater economic feasibility. The less diversified crop rotation system presented a negative economic profit. The crop rotation systems including beans presented the highest economic profit.

The objective of this study was to evaluate the viability of pasture with high production capacity and the potential for production of silage using different sources and doses of nitrogen (N) by quantifying the productivity of dry matter (DM), some qualitative characteristics, the total cost of production (TC) and total operating cost (TOC) of silage production. The experimental design was randomized block in a factorial scheme with four replications including two sources of nitrogen (urea and ammonium nitrate) and five N doses (0, 50, 100, 150, and 200 kg ha-1 by cutting). The increase in N provided greater DM and crude protein content and reduced the fiber content in neutral detergent. The source of N did not affect the chemical composition, and therefore, it is recommended to use urea due to the ease of acquisition and higher economic return. The production of Mombasa silage can be economically viable due to high DM and crude protein content combined with low production costs. The smallest TC and TOC were obtained in the absence of nitrogen fertilization; however, the proper management of N ensures high productivity in cattle feed with higher total profit when using 100 kg ha-1 N by cutting with ammonium nitrate.

Connected and automated vehicle (CAV) technologies could transform the transportation system over the coming decades, but face vehicle and systems engineering challenges, as well as technological, economic, demographic, and regulatory issues. The authors have developed a system dynamics model for generating, analyzing, and screening self-consistent CAV adoption scenarios. Results can support selection of scenarios for subsequent computationally intensive study using higher-resolution models. The potential for and barriers to large-scale adoption of CAVs have been analyzed using preliminary quantitative data and qualitative understandings of system relationships among stakeholders across the breadth of these issues. Although they are based on preliminary data, the results map possibilities for achieving different levels of CAV adoption and system-wide fuel use and demonstrate the interplay of behavioral parameters such as how consumers value their time versus financial parameters such as operating cost. By identifying the range of possibilities, estimating the associated energy and transportation service outcomes, and facilitating screening of scenarios for more detailed analysis, this work could inform transportation planners, researchers, and regulators.

Purpose This paper aims to analyze strategies that promote sustainability in higher education institutions (HEIs), focusing on the case study of a federal institute of higher education in Brazil. Design/methodology/approach The research was based on a scientific literature review on sustainability in HEIs, to identify the recurrent actions for sustainability in these institutions; and a case study of a federal institute of higher education in Brazil, to illustrate how these actions are being implemented by HEIs. Findings Concerns about sustainability, prompted by the Brazilian federal legislature, led federal HEI to change its internal processes, infrastructure and organizational culture toward sustainability. Practical implications The findings presented in this study, more specifically the sustainability plan of the Federal Institute for Education, Science and Technology of Santa Catarina, aligned with the recommendations proposed, can be used and replicated in other HEIs. Originality/value Scientific literature about organizational changes led by sustainability concerns, in HEIs specifically, still needs more attention in the academia. By addressing the case of a Brazilian public institution of higher education, this paper contributes to the literature on sustainability in higher education by reporting the process of implementation of a sustainability plan.

Resumo Este artigo discute a gramática de relações raciais e os racismos a partir do caso de um professor do Instituto Federal de Educação, Ciência e Tecnologia São Paulo (IFSP) que fez um post em seu perfil do Facebook, o qual foi denunciado por alguns segmentos sociais como racista. Metodologicamente, empreendemos um estudo de caso que foi operacionalizado a partir da averiguação e análise do que foi dito pelo professor, como também as notas emitidas pela instituição, coletivos e movimentos negros, matérias jornalísticas sobre o caso e entrevista com estudantes. Inferimos que a gramática das relações sociais com foco racial está passando por mudanças de representação, por isso, há “choque” entre os sentidos visados (coordenações formais) entre os atores. Analisamos, sob uma perspectiva weberiana, as relações sociais que se estabeleceram e entendemos que as mesmas são balizadas por probabilidades de ações dentro de um sentido visado pelos atores. Assim, olhamos as ações discursivas dos agentes que proferiram e se justificaram ao perceber a gramática das relações raciais. Para tanto, realizamos uma descrição analítica do caso construindo um aporte teórico, significando e conceituando categorias-chave, como democracia racial. Palavras-chave: Relações Raciais; Racismos; Estudo de caso. Abstract This article sought to discuss the grammar of race relations and racism from the case of a professor at the Federal Institute of Education, Science, and Technology of Sao Paulo (IFSP) who posted on his Facebook profile and was denounced as racist by some social segment. Methodologically, we elaborated a case study that analyses what was said by the professor, as well as the notes released by the institution, collectives, and black movements, newspaper articles about the case, and interviews with students. We infer that the grammar of social relations with a racial focus is provoking changes in representation, so there is a “shock” between the senses targeted between the actors. We analyze, through a Weberian perspective, the social relations that are established and we understand that they are marked by probabilities of actions within a targeted sense (formal coordination) by the actors. Thus, we look at the discursive performances of the agents who uttered and justified themselves by understanding the grammar of racial relations. For this purpose, we carried out an analytical description of the case by constructing a theoretical contribution, meaning, and conceptualizing key categories such as racial democracy. Keywords: Social Relationships; Racisms; Targeted sense. Resumen Este artículo busca discutir la gramática de las relaciones raciales y el racismo a partir del caso de un profesor del Instituto Federal de Educación, Ciencia y Tecnología de São Paulo (IFSP) que hizo una publicación en su perfil de Facebook y fue denunciado por algunos sectores sociales como racista. Metodológicamente realizamos un estudio de caso que se operacionalizó a partir de la captura y el análisis de lo que dijo el docente, así como las notas emitidas por la institución, los colectivos y movimientos negros, los artículos periodísticos sobre el caso y las entrevistas con los estudiantes. Inferimos que la gramática de las relaciones sociales con un enfoque racial está experimentando cambios en la representación, por ello se da un "choque" entre los sentidos mentados por los actores. Analizamos, desde una perspectiva weberiana, las relaciones sociales que se establecen y entendemos que están guiadas por las probabilidades de acciones dentro de un sentido específico (coordinación formal) por parte de los actores. En concordancia, observamos las actuaciones discursivas de los agentes que se pronunciaron y se justificaron al percibir la gramática de las relaciones raciales. Por ello, realizamos una descripción analítica del caso, construyendo una contribución teórica, significando y conceptualizando categorías clave como democracia racial. Palabras clave: Relaciones raciales; Racismos; Direcciones de destino.
