This study aimed to optimize the ultrasound-assisted extraction of phenolic compounds from the bagasse of umbu-cajá (Spondias bahiensis), a native Brazilian fruit, and to assess their bioaccessibility. Additionally, the influence of different concentrations of the umbu-cajá bagasse (SBB) extract on the oxidative stability of pre-cooked goat meatballs was investigated over a 10-day refrigerated storage period by quantifying lipid oxidation products. A central composite rotational design determined the optimal ethanol concentration, sonication time, and bagasse-solvent ratio. The optimized extract was applied to meatballs at two concentrations: EX2 (meatballs with 7.0 g/100 g of added SBB extract) and EX4 (meatballs with 13.7 g/100 g of added SBB extract). A control treatment (no antioxidant) and BHT-treated meatballs (0.02 g/100 g) were included as references. Meatballs were evaluated by measuring instrumental color, peroxide value, TBARS, carbonyl compounds, and through simulated digestion. Optimal extraction conditions were 55 % ethanol, 20 min of sonication, and a 1:36.8 bagasse-to-solvent ratio (m/v). The extract showed high antioxidant activity and bioaccessibility of catechin (1243.75 %), epicatechin gallate (918.75 %), procyanidins B2 (915.38 %), gallic acid (319.76 %) and procyanidins B1 (136.36 %). SBB extract slowed lipid oxidation until day 10 and protein oxidation until day 5 but did not inhibit color change. The meatballs had low content of oxidative compounds and high antioxidant capacity in the intestinal fraction, indicating that SBB extract can partially or totally replace the synthetic preservative. © 2025

Statistical trends of rainfall (annual and seasonal rainfalls) in Kerala, India were characterised using the 44-years (1980–2023) data of Modern-Era Retrospective Analysis for Research and Applications (MERRA) version 2. Monthly rainfall data were collected from the selected fifty locations which represent the state as a whole, and the collected data were then categorised into annual as well as seasonal (winter, summer, monsoon and post-monsoon) datasets based on the classification proposed by Indian Meteorological Organisation (IMD). Lag-1 autocorrelation, modified Mann Kendall (mMK), Pettitt test and Theil-Sen’s slope methods were used to determine the statistical characteristics of rainfalls in Kerala. Mean rainfalls were 3124 mm, 66 mm, 527 mm, 1667 mm and 862 mm, respectively, for annual, winter, summer, monsoon and post-monsoon periods. mMK based statistical trend analysis revealed an overall decreasing trend characteristics in annual (-0.54 mm.y⁻¹), monsoon (-1.20 mm.y⁻¹), and post-monsoon (-0.93 mm.y⁻¹) seasons whereas winter and summer rainfalls showed an increasing trend (0.67 mm.y⁻¹ and 3.40 mm.y⁻¹, respectively) for the state as a single unit. Pettitt test indicated four dominant periods of change in rainfall characteristics in the study area that spanned over the decades of 1980, 1990, 2000 and 2010, in which major changes in annual and seasonal rainfalls were occurred during 1990’s, 2000’s and 2010’s. Theil-Sen’s slope-based estimation of rate of change in rainfall showed an average variation of -4.33 mm.y⁻¹, 0.17 mm.y⁻¹, 6.27 mm.y⁻¹, -6.54 mm.y⁻¹ and − 3.28 mm.y⁻¹ for annual, winter, summer, monsoon and post-monsoon seasons, respectively. Though the winter and summer rainfalls showed an increase in its rate during the period of analysis, annual rainfall showed an overall reduction in the amount of rainfall received in the state.

Latin American Business Review 2019年第1期20卷 83-107页

The young Latin American democracies have been structuring their political parties for day-to-day management. In this context, it is important to understand how such structures could be affected by the so-called invisible side of organizations, which are composed of networks of relationships between elected politicians and then relationships between these and external militant groups, which can greatly influence the candidates’ performance and the very dynamics of the party. This article seeks to unravel some of these dimensions. We select for analysis the case of the PCdoB (Communist Party of Brazil), in the Metropolitan Region of Belo Horizonte, state of Minas Gerais, Brazil. The results show the nature of the embeddedness of these actors in the political system, highlighting weaknesses and possibilities. © 2019, © 2019 Taylor & Francis Group, LLC.

Regarding the solution of combinatorics problems, is important to evaluate the cost and the benefit among obtaining solutions of high quality in detriment of the computational resources required. The problem presented here is about the routing of a vehicle with pickup and delivery of product with time window constraints. This problem requires to be attended with instances of great scale (nodes ≥ 100). We have a large quantity of nodes with restrictions of time windows (≥ 90%) and with a large factor of amplitude (≥ 75%) as well. The problem is NP-hard and for such motive the application of an exact method of solution to resolve it, is limited by the practical time for routing. This paper proposes a specialized genetic algorithm, which offers solutions of good quality in computational times that do useful its application. © 2005 IEEE.

Model Assisted Statistics and Applications 2022年第4期17卷 259-264页

作者： Garg, Nishesh Gupta, Narain Post Graduate Program in Management (Executive) MDI Gurgaon India Operations Department MDI Gurgaon India

A global revolution is called upon to transition into renewable sources of energy from fossil fuels in an accelerated manner by various countries to become net zero carbon emitter with self-committed timelines. This study identified carbon dioxide emissions and participation of renewable energy in total energy supply as two major dimensions and discusses the impact of various independent variables quantitively by multipanel regression in timeseries and countries for comparative correlation analysis. Theme based industry expert interviews adds qualitative dimension to the study. The results suggest that country's energy need and availability of fossil fuels within, determines the RE adoption rate, while countries with high reliance on coal and crude are shifting towards RE sources. Investments in research and development in hydrogen, fuel cells and storage are yet to make an impact in this direction since they are recent in this long game of energy transition. © 2022-IOS Press.

Web accessibility has been the subject of much discussion regarding the need to make Web content accessible to all people, regardless of their abilities or disabilities. While some testing techniques require human intervention, accessibility can also be evaluated by automated tools. Automated evaluation tools are software programs that examine the code of Web pages to determine if they conform to a set of accessibility guidelines that are often based on the Web Content Accessibility Guidelines Version 2.0 (WCAG 2.0), developed by the World Wide Web Consortium (W3C). In this context, the purpose of this study is to analyze an automated software program for evaluating authenticated environments and verify the usability of this tool, since automated systems require precision and reliability in terms of both results and use in any type of environment. With this in mind, this paper aimed at evaluating the ASES software by means of a heuristic evaluation carried out by three experts. The analysis revealed major accessibility problems, as well as improper functioning of available tools and inconsistency of results. Furthermore, ASES was found to have problems of efficiency, interaction, validity, and reliability in the results presented. Considering that this is an open-source accessibility testing tool that can be found on a government web site, the correction or improvement of the system's deficiencies identified in this study is highly recommended, as there is a lack of software available to evaluate authenticated environments. © 2014 Springer International Publishing.

Efficient production planning requires well-structured models compatible with metaheuristic and other optimization techniques. This study compares three established metaheuristic methods - sanitized-teaching-learning-based optimization (s-TLBO), Particle Swarm Optimization (PSO), and Differential Evolution (DE) with a termination criterion of equal number of functional evaluations - for profit-maximizing production planning. The focus is on a single-level problem involving complex constraints, non-linear costs, budget and raw material limitations. The paper presents two solution strategies: a penalty-based and a correction-based approach. Analyzing 300 unique instances of the problem reveals that s-TLBO implemented with correction-based approach consistently outperforms the other methods in devising optimal production plans for two Saudi Arabian petrochemical industries with 24 products, 54 processes, and three raw materials for plant 1 and two raw materials for plant 2. © 2024 IEEE.

To enhance production planning efficiency, it's crucial to have well-structured models that align with metaheuristic and other optimization techniques. This research conducts a comparative analysis of three unique metaheuristic methods: sanitized-teaching-learning-based optimization (sTLBO), Particle Swarm Optimization (PSO), and Differential Evolution (DE) with a termination criterion of equal number of functional evaluations. The primary focus lies on profit-maximizing production planning within a single-level framework, encompassing intricate domain constraints, nonlinear costs, budget limitations and raw material constraints. The paper introduces three correction-based solution approaches. Upon evaluating 300 distinct instances of the problem, the study reveals that s-TLBO integrated with correction-based approach 1 and 3 consistently outperforms the other methods when it comes to devising optimal production plans for a Saudi Arabian petrochemical industry. This industry scenario involves 24 products, 54 processes, and three raw materials. © 2024 IEEE.
