El miedo y la muerte en Edgar Allan Poe y su influencia en “El que se enterró” de Miguel de Unamuno
Authors: Martínez Ruiz Gema
Published: March 2023

La narrativa breve de Miguel de Unamuno ostenta una más que notable riqueza filosófica, y se ve influenciada por muchos de los pensadores y literatos más importantes de la Historia. La dialéctica, clave para comprender la naturaleza de sus relatos, es un elemento fundamental dentro de su literatura, ya que enfrenta fuerzas opuestas que coexisten entre sí. Es esta la lógica que se aprecia en uno de sus relatos más interesantes, “El que se enterró”, siendo un cuento que habla de la muerte, el temor y la vida. En este relato puede apreciarse una notable influencia de la narrativa breve de Edgar Allan Poe, sobre todo en lo que se refiere al tratamiento del miedo y de la presencia de la muerte, elementos clave de la literatura de terror del estadounidense. De este modo, este trabajo pretende relacionar ambas obras estudiando los conceptos de miedo y muerte, observando la importancia que tienen tanto en Unamuno como en Poe, para analizar cómo ha influido la obra de Poe en el bilbaíno.

La noción de frontera en Todo eso es yo
Authors: De Diego Pérez de la Torre Alba
Published: March 2023

El objetivo del presente artículo es reflexionar sobre la polisemia que entraña el concepto de «frontera» en la actualidad y su interrelación con otros fenómenos a los que suele ir aparejado, tales como: la escisión (y el diálogo) cultural, la violencia y, por último, el impacto que dicha situación desfavorable tiene sobre la construcción de la propia personalidad del individuo, llevando a sentimientos de desarraigo y alienación. Para ello, se tomará como base la novela Todo eso es yo, que refleja la complejidad intrínseca a este término a partir de una de las fronteras que, por desgracia, ha copado los medios de comunicación de los últimos años: la frontera entre México y Estados Unidos.
Heterotopía y desacralización en La Regenta. Posibilidades de transfiguración espacial
Authors: Bustelo Vega Ana
Published: March 2023

Es una característica común a gran parte de las obras del realismo decimonónico español el registrar numerosas deformaciones espaciales. El avance del Liberalismo, el auge de la burguesía y el surgimiento de nuevas formas de ocio promueven la transfiguración de los espacios, ajustándolos a sus nuevas funciones. Por tanto, este artículo pretende constituir una propuesta de trabajo, un adentramiento en las posibilidades de análisis de La Regenta a la luz de un estudio heterotopológico, descubriendo dicha tendencia a complejizar la legibilidad de las localizaciones, a la subversión de los espacios, especialmente en forma de heterotopías, sacralizaciones y desacralizaciones.
Poética de la imagen creacionista en Gerardo Diego: genética del poema y morfología de su lenguaje lírico
Authors: Conde Arroyo Pau
Published: March 2023

Este artículo plantea una aproximación teórica a la poética creacionista de Gerardo Diego con el objetivo de clarificar y precisar el papel que juegan la metáfora y la imagen en ella. Se plantea que la distinción entre ambas fundamenta la deriva creacionista de Diego, de modo que se examina su prosa crítica confrontándola con otros textos críticos sobre poética de algunos de sus coetáneos, como José Ortega y Gasset, Jorge Luis Borges y Juan Larrea. Así, se atienden los planteamientos programáticos y taxonómicos que abordan matizadamente la distinción entre metáfora e imagen en el seno de la producción lírica para dar cuenta de la controversia en torno al significado poemático.
Pretreatment efficacy and lignin solubility of organic solvents on juvenile slash pine chips for lignin value prior to pulping
Authors: Kwok Thomas T. , Bright John R. , Realff Matthew J. , Bommarius Andreas S.
Published: March 2023

Organic solvent treatment of wood chips can be a key to converting pulp mills into pulp-producing biorefineries. Choosing an optimal solvent requires screening of numerous industrially relevant solvents. This work considers the delignification efficacy of several aqueous organic solvents for juvenile slash pine chips and correlates this efficacy to the lignin solubility. No correlation was shown between the pretreatment efficacy and solubility of ethanol-extracted lignin in organic solvents. At least 10% (v/v) water and 10% (v/v) organic solvent are required for effective delignification, and the different solvent delignification profiles for aqueous mixtures of 1,6 hexamethylene diamine, ethanol, 1-methylimidazole, tetrahydrofuran, and ethylene glycol were determined experimentally. No correlations were found between lignin solubility, Hansen solubility parameters, and delignification. Therefore, solubility measurements should not be a screen for lignin value prior to pulping. However, a 50% (v/v) organic solvent pretreatment at 200 °C for 2 h is a valuable screen to rank the delignification efficacy of organic solvents for further optimization.
Effects of brown-rot decay on the electrical resistance of wood and its mechanism
Authors: Xu Huadong , Li Qizhe , Xu Qun , Bao Zhenyu , Wang Lihai , Xing Tao
Published: March 2023

The objective of this study was to investigate the effect of decay on the electrical resistance (ER) of wood with a high moisture content (> 45%) and to try to determine the mechanism. Poplar wood blocks were exposed to a brown-rot decay fungus (Gloeophyllum trabeum (Pers. ex. Fr.) Murr.) for 2 to 12 weeks to obtain different degrees of decay. The ER values of the non decayed and decayed wood at various moisture contents were measured using a voltammetry method and were statistically analyzed. It was found that the ER of the wood blocks decreased with the fungus exposure time. Changes in the ER were quick during the first 2 weeks of exposure, which suggested that it can be used to assess early wood decay. The ER values of the decayed wood at different moisture contents were generally lower than that of the non decayed wood. A large difference (approximately 50 kΩ) was found between them when the wood moisture content was above 45%. Further analysis showed that this was because of the increase in conductive ions in the wood, rather than an increase in the moisture content. These results may be helpful to better detect the internal decay of trees using ER-based methods and could partly explain ER differences in decayed trees.

Published: March 2023

A fluidized bed reactor pyrolysis process with recycled non-condensable gases was designed for a capacity of 5 kg/h based on previous basic studies of key parts. The main components of the pyrolysis process were introduced, and the performance was appraised. Initial experiments were conducted between 450 °C and 550 °C to characterize the bio-oil at different temperatures, using non-condensable gas as fluidizing medium. Simultaneously, the contents and higher heating value of non-condensable gases were determined. The results showed that the excellent efficiency of cooling and of capturing the organic compounds, contributing to a high yield of bio-oil and clean non-condensable gases. At 500 °C, the highest yield of bio-oil reached 55.6 wt%, and the yields of bio-char and gas were 23.4 wt% and 21 wt%, respectively. Non-condensable gas not only carried the organic compounds, but also participated in fast pyrolysis. However, temperature was the major factor affecting the chemical components of bio-oil. The heavy bio-oil mainly included long chain macromolecules and phenols. Higher temperature favored degradation and gas purification.
Chemical attributes of Gigantochloa scortechinii bamboo rhizome in relation with hydraulic conductance
Authors: Mohamed Johar , Hamid Hazandy A. , Nuruddin Ahmad A. , Majid Nik M. N. A.
Published: March 2023

Chemical changes during the maturation period of bamboo are believed to affect its conductance ability. However, prior studies on the bamboo’s chemical changes were inconclusive in implying that the maturation period affects the rhizome’s conductance ability. The rhizome’s conductivity is crucial to rapidly grow a new bamboo sprout. The aim of this study was to determine the variation of chemical attributes among study sites during the maturation period of bamboo rhizome (Gigantochloa scortechinii), and investigate the possibility of a relationship between the chemical attributes and hydraulic conductance. Destructive sampling was conducted using the selective random sampling method on four consecutive rhizomes. The chemical attributes were determined according to the TAPPI standard methods, except for the holocellulose. The results indicated that the ash content, alcohol-acetone solubility, and holocellulose were significantly different (p < 0.01) among the three study sites. In addition, the results indicated that decreasing ash content with age could not be used as a determinant factor for the decrease in the hydraulic conductance. However, increasing the hot water solubility, alcohol-acetone solubility, lignin, and holocellulose with the rhizome age were suggested to be related to decreasing the rhizome’s hydraulic conductance.
Characteristics and outcomes of Marijuana users admitted with sudden cardiac arrest
Authors: Mathew Don , D.O Jay Kim , Sherif Akil A
Published: March 2023

Background: Marijuana or Cannabis is the most commonly used illicit drug in the United States. An estimated 2 million adults who reported marijuana use also have cardiovascular disease. Marijuana use has been associated with acute myocardial infarction, heart failure and arrhythmias. However, the implications of marijuana use on sudden cardiac arrest outcomes is unknown. Methods: Using the National Inpatient Sample of the years 2018 & 2019, patient characteristics and in-hospital outcomes were compared between marijuana users and non-marijuana users admitted with sudden cardiac arrest. Results: The median age of marijuana users was lower at 46.8years. They had significantly lower prevalence of congestive heart failure, coronary artery disease, valvular heart disease, pulmonary circulation disorders, atrial fibrillation, hypertension, and diabetes and a significantly higher prevalence of chronic liver disease, depression, alcohol use, tobacco use, amphetamine/psychostimulant use, opioid use, cocaine use, and sedative use. Multivariable logistic regression analysis showed significantly higher odds for ventricular fibrillation (OR: 1.24; 95% CI: 1.09- 1.41; p- 0.001) but lower odds for mortality (OR: 0.86; 95% CI: 0.78- 0.96; p-0.011), need for mechanical ventilation (OR: 0.76; 95% CI: 0.67- 0.86; p- 0.000), and tracheostomy (OR: 0.46; 95% CI: 0.34- 0.62; p- 0.000). Marijuana users were also more likely to be discharged home with self-care (25.25% vs 11.53%). Conclusion: Among patients admitted with sudden cardiac arrest, marijuana users were found to have significantly higher odds for ventricular fibrillation. They were found to have lower odds for in-hospital mortality, mechanical ventilation, and tracheostomy and were more likely to be discharged home with selfcare, but this is mostly because marijuana users who are admitted with sudden cardiac arrest were younger and had considerably fewer chronic medical conditions. Large prospective cohort studies are needed to ascertain the health risks associated with marijuana use.
Perfil de Agenciamento dos Chief Executive Officers de maior sucesso no Brasil: O caso Forbes e a relação com remuneração executiva.
Authors: Oliveira Alexandre Silva de , Sonza Igor Bernanrdi de , Von Ende Marta _
Published: March 2023

Este trabalho objetiva analisar o perfil de agenciamento dos Chief Executive Officers (CEOs) de maior sucesso no mercado Brasileiro segundo a classificação FORBES. A base teórica que fundamenta o trabalho é a teoria do Valor Econômico Criado (VEC) de Malvessi (2001). Como metodologia busca-se replicar o procedimento descrito pela revista para premiar os agraciados no ano de 2019, com a utilização do Valor Econômico Criado (VEC), do ano de 2018 e do valor médio do VEC entre 2010 e 2018. Também trata os dados em painel para análise da relação entre a remuneração dos executivos e o VEC. Na validação os resultados das empresas ativas na Bovespa, totalizando 417 empresas, são analisados durante o mesmo período. Apesar dos premiados serem profissionais experientes e qualificados, os resultados não confirmaram o ranqueamento estabelecido pela Forbes e apontam que a remuneração dos executivos não é uma boa variável para explicar o desempenho das empresas no VEC.  Este trabalho contribui para a literatura e para a prática, uma vez que não se encontram trabalhos publicados, avaliando a transparência e confiabilidade das premiações e ranqueamento do desempenho dos profissionais do mercado.

Published: March 2023

O Imposto Predial e Territorial Urbano (IPTU) é um dos principais impostos cobrado pelas prefeituras, entretanto, em parte dos municípios a arrecadação do IPTU não é suficiente para cobrir seus gastos. O objetivo desse estudo é descrever os meios utilizados para a definição dos valores cobrados do IPTU no município de Jataí (GO) e discutir as estratégias de administração municipal para sua cobrança. A elaboração desse estudo foi constituída por duas etapas: pesquisa e revisão bibliográfica, e estudo de caso a partir da coleta e análise dos dados. Nas análises qualitativas teve-se a descrição, definição e explicação do fenômeno estudado, já nas análises quantitativas deu-se ênfase na objetividade, na análise dos dados e na utilização de ferramentas estatísticas. Verificou-se por este estudo a importância da atualização do mapa urbano e da planta de valores para o cálculo do IPTU, e o papel da administração pública nesse processo. Apesar do alto investimento para tal, foram evidenciados ganhos na otimização dos serviços e na possibilidade de correções de irregularidades para uma justa e transparente cobrança de tal imposto. Para outras pesquisas sugere-se verificar a possibilidade de uso de programas gratuitos que sejam capazes de atualizar ou aprimorar os serviços nas prefeituras.
Processo de seleção de ações listadas na bolsa de valores de São Paulo B3 utilizando os métodos multicritérios TOPIS
Authors: Domingues Maciel neto Jaime , Figueiredo Pinto Antonio Carlos , Cabús Klötzle Marcelo
Published: March 2023

A bolsa de valores de São Paulo, a B3, apresentou grande crescimento nos últimos anos, onde o IBOVESPA saiu de cerca de 45.000 pontos em 2015 para mais de 100.000 em 2020. O crescimento não se mostrou apenas no aumento expressivo do IBOVESPA, mas também pelo aumento do número e mudança do perfil de investidores, com maior participação pessoas físicas, destacando-se jovens e o maior participação de mulheres. Tendo em vista que o método de apoio à decisão TOPSIS (Technique for Order Preference by Similarity to Ideal Solutions) é um método de fácil aplicação, que não requer grandes dispêndios computacionais, aplicou-se este método considerando os principais índices fundamentalistas do último trimestre dos anos de 2010 a 2019 para selecionar as 5 mais bem ranqueadas pelo método e comparar o desempenho dessa carteira selecionada no ano subsequente da seleção com o IBOVESPA. Observou que o método conferiu maior resiliência a carteira que o índice no período de baixa da bolsa (2011 a 2015), ou seja, apresentou melhor resultado. No entanto, no período de alta (2016 a 2020) o IBOVESPA teve melhor desempenho que a carteira selecionada pelo método. Com esses resultados, concluiu-se que o método TOPSIS pode ser utilizado no processo de seleção de ações, mas não deve ser aplicado de forma isolada, mas sim como uma ferramenta a ser utilizada em conjunto de outras análise para formação de carteira.

Published: March 2023

El dextrano es un homopolisacárido de glucosa, formado en el jugo de caña de azúcar durante la postcosecha y es responsable de los bajos rendimientos de la evaporación y cristalización en la industria azucarera. La sacarificación enzimática del dextrano se ha destacado por sus rendimientos satisfactorios; sin embargo, dicho proceso enzimático requiere de una adecuada selección de la enzima y su concentración, así como el control de las condiciones ambientales de la biocatálisis. El objetivo de la presente investigación fue optimizar el proceso de hidrólisis enzimática de dextrano del jugo de caña de azúcar mediante la metodología de superficie de respuesta. Se utilizó un diseño central compuesto rotacional con tres factores independientes de cinco niveles: concentración de enzima, tiempo y temperatura de reacción y como variable respuesta: la reducción de la concentración de dextrano. Se utilizó la enzima comercial Dextranfree Xe la cual fue caracterizada cinéticamente. El experimento consistió en dos etapas, primero se utilizó un medio simulado de jugo de caña para determinar las condiciones óptimas y éstas aplicarlas después al jugo real de caña de azúcar.  Las condiciones ambientales óptimas de hidrolisis del dextrano en el simulado de jugo de caña resultaron ser: concentración de enzima 224 ppm, tiempo de reacción 32 minutos y temperatura de reacción 36 °C, para alcanzar un 70% de reducción de dextrano. Finalmente, las condiciones optimizadas fueron validadas aplicándolas al jugo de caña de azúcar, obteniéndose una reducción del 69.2% de concentración de dextrano; concluyéndose que dicho método fue efectivo.

Students can comprehend the conceptual contents of any subject in general, by three methods: by involving in experimental activities in physical lab, by simulating the experimentation through Virtual Laboratory (now on, VL) and simply by visualization. But the visualization method is relatively difficult as it demands a lot of attention and subject expertise and hence will only help in the later stages of learning process. Physical lab set up inherently has certain obvious constraints like accessibility, time, cost etc. The VL is the buzz word in the current scenario of booming e- learning and online classes. VLs are computer simulations that make real life conditions. Research studies in the past have demonstrated the utility of integrating VL tools with traditional teaching methods in enhancing students understanding, thinking and creativity. The present case study deals with evaluating student’s engineering chemistry learning outcomes in terms of scores secured in internal assessment test. The study also aimed at identifying and analyzing the data collected through robust feedback system, about the effectiveness of VL tools in increasing students’ understanding, active participation in classes and performance.

In recent years’ students are very reluctant to read books for studying for any course. They are preferring only teachers’ notes or PowerPoint slides and mobile apps for exam study. Any type of information or study material is easily available on various networking sites. This can lead to poor interest and less engagement of students in the classroom teaching learning process. Also, in class activities are not fulfilling the expected level of learning of students, especially in the conceptual courses. So students need an activity based learning approach in the classroom. Nowadays most of the teachers in engineering institutions face these challenges. Hence, to utilize the capabilities of students, make them aware of course related books and achieve expected level of learning of students, a poster presentation module was implemented. In this practice paper, implementation of poster development and presentation (PDP) to improve learning of course fluid mechanics and machineries is detailed. This PDP approach empowers the student in life-long learning skills. Keywords— Poster development and presentation, assessment, book reading, life-long learning.

Problem based learning, finding its root from the medical practices is now a widely used approach in several other domains. The method has also been used in computing and explored and researched with the programming courses as well. This work proposes one such model for first year c programming. A variant of the model was adapted to first design problem scenarios to teach the concept philosophy and then explain the underlying concept with c realization and its syntax. The students coming from non-circuit branches and having lower intrinsic motivation to study the course have shown gradual interest and motivation towards the much-needed 21st century skill. On finding that they lacked the debugging skills, even the syntax was explained with design philosophy and problem based learning. Understanding the class behavior being the research question, the work was analyzed using the mini-ethnography qualitative study. The study was carried out for a month span with seven sessions. The data was collected using observations and forms, and also thematic coding was carried out for the data analysis. The discussion section presents the analysis of the model proving the method to be an effective methodology for teaching and learning. Even the feedback collected for the model is positive and can be employed to teach other courses as well. Keywords—Mini-Ethnography; Problem Based Learning; Programming; Problem Solving

This paper presents the experiences and outcomes of teaching an elective course Multicore Architecture and Programming (MCAP) with an automotive industry- (Bosch Global Software Solutions, Bangalore, (BGSW).The practices and outcomes of the course for two different batches with two different modes of delivery, the online and physical mode are discussed. MCAP is a course which deals with higher levels of embedded systems concepts; hence for an effective learning and also to impart industry experiences, we adapted a co-design, co-delivery and coassessment with industry. The course is designed involving core concepts of MCAP, hands-on sessions, and also industry use cases. The delivery of the course is planned with both regular lectures by instructors and industry experts. The assessment was done for the hands-on sessions, higher cognitive level assignments and through end semester exams. The assignments were designed with the help of industry to assess higher cognitive level learning. The delivery and assessment happened in online for the first batch and in physical for the second batch. The outcomes of the course for both the batches were convincing, with the students readiness of having skills applied to embedded industry and concept learning. The students showed a lot of interest and enthusiasm to learn throughout the course, and this resulted in most of the students getting placed in automotive/embedded industry. Few students with interest further continued in the same area and have taken higher semester projects, internships and placements in the same area which aided them to choose their career ahead.

Unit Operations is the hallmark course of Chemical Engineering and allied disciplines. This involves the separation of products by physical means such as Distillation, Extraction, Gas absorption, Crystallization, Evaporation, Filtration, etc. Unit Operations course is usually offered in the second year of the undergraduate program in Biotechnology. The conventional pedagogy practiced to date was not so effective in the attainment of certain Program Outcomes (PO). To address this issue, categorization of the laboratory was done into four types: Demonstration, Exercise, Structural inquiry, and Open-ended experiments was made. The experiments were carefully designed to address some of the major Technical and Professional outcomes. Assessment criteria for each kind of experiment were mapped to Program outcomes, Outcome elements, and Performance Indicators. This helps in the evaluation of the attainment of Program Outcomes more accurately. The present study deals with an active and collaborative learning approach in the Unit Operations laboratory by framing Open-ended experiments using the concept of Design of Experiments (DoE). Full Factorial Design(FFD) and Response Surface Methodology(RSM) concepts were used to study the effect of various parameters on Liquid-Liquid Extraction operation. The study helped in addressing the Program Outcome-4 defined by the National Board of Accreditation, which is related to conducting investigations of complex problems. The evaluation of the students’ performance was done using rubrics-based methodology, and attainment of the graduate attributes addressed were documented. Quality students’s feedback was taken to identify scope for further improvement in the teaching-learning process.

Feedback is central to the development of student learning. The purpose of feedback is to address the learning gaps at the earliest possible stage of learning cycle. This paper presents the use of instant feedback in classes with the help of Audience Response System (ARS) in teaching of a First Year Engineering subject. The ARS is used to pose a few questions intermittently during a lecture on students' mobile phone. The students’ responses are used to identify the Strengths, Weaknesses, Opportunities and Threats (SWOT) based on correctness and confidence levels. SWOT analysis of every individual student allows a teacher to provide personalized coaching on the basis of the topics identified as areas of opportunity, threat and weakness. The performance of the entire class is also monitored at regular intervals.

Mentoring has a good impact and influence in undergraduate STEM students' perseverance. It is crucial in any profession and engineering is no exception. By supporting them in directing their efforts and by helping them create objectives and receive feedback, mentors may encourage and facilitate both professional and personal growth. In order for a mentee to maximize their potential, develop their skills, and transform into the person they want to be, mentoring involves guidance and support in the way they manage their learning. With this as the driving force, an effort is made in this study to develop a survey instrument to capture the understanding of the first-year engineering students in relation to the roles and responsibilities of mentors in engineering course, mentors' attention to the physical and mental health of students, goal-setting, mentees' skill development and maintaining trust and confidentiality. In fall 2022, a survey instrument was developed for quantitative analysis and administered to first-year engineering students at an autonomous college HITAM in South of India, 263 participants responded. The survey instrument's factor structure was determined using exploratory factor analysis (EFA), which yielded four factors. The Cronbach's α ranged from 0.67 and 0.92 and for factors' minimum and highest loading were 0.43 and 0.92. This survey instrument could be utilized by a varied institution in order to evaluate students' present levels of understanding for accountabilities and duties of mentors, to assist and encourage mentees learning so that they can reach their full potential and enhance their abilities.

The purpose of this study was to reveal Title IX fueled obstacles which prevent Black women from achieving equity in college sports. The researchers sought to provide a critical analysis of the synchronous burden of race and gender discrimination experienced by Black women in college sports. The study found this form of discrimination is unique to Black women as they experience sex discrimination similar to white women and race discrimination similar to Black men, but neither white women or Black men experience simultaneous forms of race and gender discrimination as Black women do (Crenshaw 1988; Mathewson; 1996). Title IX is a single-axis equity law which uses sex to factor discrimination, yet as Black women experience both race and gender discrimination synchronously this law does not protect Black women from discrimination in the way they experience it. Yet, examining the effectiveness of Title IX to prevent race and sex discrimination is problematic because even with the law, schools have not achieved gender equity in college sports  since its enactment in 1972 (Butler & Lopiano, 2003; Cooper & Newton, 2021;Kaplan, Hecker, & Fink, 2021; NWLC, 2022; Staurowsky, 2011; 2020; 2022). Another challenge is the NCAA Emerging Sports Program for Women uses a single axis lens to increase athletic opportunities for women. Therefore Black women are barred from benefiting from the increased access and athletic opportunities produced through the Emerging Sports program as it uses sex as a solo determinant to increase athletic opportunities. It is worth noting the extreme lack of research on Black women in sports has rendered Black women college athletes invisible in data on women’s sports (Butler & Lopiano, 2003; Carter-Francique & Flowers, 2013; Cooper & Newton, 2021; McDowell & Carter-Francique, 2017; Pickett et al, 2012; Staurowsky et al., 2021; 2022). This adds to the complexity of examining forms of discrimination experienced by Black women in college sports. The study found racial clustering, the single-axis lens of Title IX, and NCAA gender equity programs collectively provide harm to Black women in college sports and uniquely attack their ability to achieve equity in college sports.

The purple corn cob is an agro-industrial by-product that contains high-value bioactive compounds, which makes its use attractive for the development of extraction processes. The aim of this research was to extract the bioactive compounds from the purple corn cob by high isostatic pressure at different processing temperatures. Pressures of 0.01 MPa, 250 MPa, 450 MPa and 650 MPa for 3 minutes and at temperatures of 25 °C, 45 °C and 65 °C were used. High pressure extraction was compared with conventional extraction (2.5 h at 25°C). The purple corn cob extract obtained by isostatic processing at 650 MPa and 65 °C presented high antioxidant activity and content of bioactive compounds, unlike the conventional extraction of 2.5 h and 65 °C (p < 0.05). However, it did not show a significant difference with the extract obtained at 450 MPa and 45 °C (p > 0.05). Seven different anthocyanins were identified by liquid chromatography in the extracts obtained by high isostatic pressure (650 MPa at 65 °C) and hydroalcoholic maceration (2.5 h at 65 °C), mainly cyanidin-3-glucoside, pelargonidin-3-glucoside and peonidin-3-glucoside, and their respective malonyl derivatives. The high isostatic pressure increased the extraction of bioactive compounds by more than 50% and obtained them in shorter times, thus appearing as a new alternative, and eco-friendly method for the extraction of bioactive compounds from plant tissues.

Drought is an extreme climatic event that generates large impacts and losses in agriculture, causing the increase of global food insecurity and unsustainability of rural livelihoods. Based on this, the objective of this research was to conduct a systematic review of empirical studies that have reported the relationship between risk perception and adaptive strategies of farmers in the face of drought. For this reason, the review followed the guidelines and recommendations of the PRISMA statement. The databases consulted were Web of Science, Scopus and EBSCO. In total, 50 empirical studies, in Spanish and English, published between 2010 and 2021, that met the selection criteria were reviewed. The results highlight thdifferent factors influencingisk perception (years of experience, level of schooling, among others) and adaptation strategies (farm size, gender, access to credit, etc.). Finally, the effects of drought at the crop, livestock, personal and environmental levels were identified. In conclusion, we discuss its implications and limitations, highlighting the absence of studies in the Latin American region and in Spanish language. Future studies should be done with a place-based perspective, under which adaptive knowledge, beliefs, practices and actions can be recognized. On the other hand, climate change mitigation policies and programs must be proposed and implemented at a local scale.

Published: March 2023

Fruit waste is rich in phenolic compounds, including flavonoids with pharmacological potential for health, nutraceutical and technological properties. To characterize them, High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) was used, used for its high separation efficiency by HPLC and structural information from MS, a technique that allows analyzing a wide range of analytes in plant matrices. This study aims was to perform a systematic analysis based in SCOPUS of scientific productions of studies on techniques for detection and identification of flavonoids by HPLC-MS in fruit waste available in Latin America, between the years 2010-2022. Thus, the countries with the highest scientific production are Brazil (58.9%), Mexico (16.1%), Chile (9.2%), Argentina (7.1%) and Colombia (3.8%). There were also studies in collaboration with researchers from the USA and Europe. A total of 15.1% of the studies used HPLC-MS for determining these compounds, generally related to by-products of native or non-traditional fruits. It is known that agro-industrial waste matrices are chemically complex, being necessary analytical techniques such as HPLC-MS, which awakens interest for their study and the possibility of being isolated from vegetable by-products such as fruits. This is a green technology alternative to achieve sustainable use of this waste and be exploited by the food industry.
