The first evidence of cryo-milling improving enzymatic production of chitooligosaccharides from chitin biomass
Authors: Mukherjee Saumashish , Sarma Sreedhara Sudhakara , Rao Tata Narsinga , Madhuprakash Jogi
Published: January 2024

Cryo-milling offers an energy-efficient approach to process α-chitin, the most prevalent and well-structured chitin form. In contrast to ball-milling, cryo-milling operates at low temperatures (<123 K), preventing heat-related charring and chitooligosaccharide loss. This study explored various cryo-milling conditions' impact on α-chitin, resulting in reduced crystalline plane intensity, increased surface area and smaller particle size without substrate breakdown or functional group loss. Additionally, the study investigated cryo-milled α-chitin's enzymatic hydrolysis for the first time. Using Paenibacillus sp. LS1's chitin-active-secretome, cryo-milled α-chitin exhibited a twofold increase in GlcNAc yield compared to unmilled α-chitin. Hydrolysis with recombinant Chi5 from Paenibacillus sp. LS1 resulted in twofold and fourfold increments in (GlcNAc)2 and GlcNAc yield, respectively. Overall, cryo-milling emerges as a gentle and effective alternative to ball-milling. It reduces α-chitin crystallinity and particle size, and increases the available surface area for enhanced enzymatic saccharification, thereby facilitating chitooligosaccharide production.
Temor perpetuo y la chispa del odio en La conjura contra América
Authors: Bustamante Petit Armando
Published: January 2024

¿Qué hubiera pasado en Estados Unidos si un candidato pronazi hubiera ganado las elecciones presidenciales de 1940? La miniserie original de HBO, basada en el libro homónimo de Philip Roth, reescribe la historia mientras se pregunta si algo similar podría ocurrir hoy, en una sociedad polarizada que, bajo ideas radicales, ve a las minorías como una amenaza. Desde la mirada de la familia y el barrio, retrata una pesadilla americana al cuestionar su propia imagen nacional y la fragilidad de un democracia que, aparentemente, no es inmune al virus del fascismo.

Estudio de Audiencias Interseccional: Jóvenes Cisgénero y Heterosexuales en Apps de Citas
Authors: Vasen Isabel
Published: January 2024

Inscripta en el campo de Comunicación y Género, la presente investigación cualitativa indaga en cómo el consumo de las apps de citas y la sociabilidad erótico-afectiva circundante están condicionados por el entrecruzamiento de la clase social, el género, y la sexualidad entre jóvenes cisgénero y heterosexuales residentes en el Área Metropolitana de Buenos Aires. Para ello, se realizaron veintidós entrevistas semiestructuradas a usuaries que fueron analizadas mediante una codificación temática y una codificación axial. En primer lugar, el consumo de las apps de citas está estratificado socialmente, lo cual refuerza la homogamia de clase y termina por producir una plataformización del espacio social. Esto pone en tela de juicio la noción de contrato de lectura, en tanto la preferencia por una app u otra no sería exclusivamente enunciativa, sino que el factor de la clase social tendría más peso. Asimismo, presenta un caso de enclasamiento del consumo de medios digitales que se agrega a la generización descripta por investigaciones recientes. En segundo lugar, las interacciones están regidas por un ritual de cortejo cisheteronormativo que sanciona y disciplina a quienes intentan transgredirlo. Se destaca el caso de las mujeres cisheterosexuales entrevistadas que quieren empezar a salir con mujeres y no lo logran por “problemas de comunicación”. En un contexto de cambio social incitado por la masificación de los feminismos, las subjetividades cambian más rápido que las estructuras interaccionales y se produce una histéresis. Finalmente, el artículo ofrece futuras líneas de investigación.

Published: January 2024

Caenorhabditis elegans has been used as a central model system for broad-spectrum
research studies across diverse modern biological domains. A study was conducted to
evaluate the potential of sunflower oil-based nanoemulsions for lifespan enhancement in
stressed C. elegans worms, that had been fed on nematode growth media (NGM) seeded
with two strains of pathogenic bacteria (Salmonella enterica serovar Typhimurium and
Staphylococcus aureus). Nanoemulsions were fabricated using HI-CAP®
100 modified
food starch, and their stability was tested under different processing conditions
(temperature, pH, ionic strength) over a period of 5 months. Lifespan assay results
demonstrated that sunflower-oil-based nanoemulsions with droplet size 170.2±9.3 nm,
significantly facilitated the growth of C. elegans under stress conditions and increased the
lifespan of the worms from the previously recorded 11 days to 26 days in the current

flavonoids from four different grades of Zhenghe white tea (arranged from lowest to
highest): Shou Mei (SMT), Gong Mei (GMT), White Peony (WPT) and Silver Needle
(SNT). The ultrasound-assisted extraction parameters (ethanol concentration, liquid-solid
ratio, ultrasonic power and extraction time) were optimised to produce crude flavonoid
extracts. The optimal parameters were as follows: SMT (60%, 42:1 mL/g, 130 W and 45
mins); GMT (67%, 40:1 mL/g, 100 W and 43 mins); WPT (47%, 31:1 mL/g, 110 W and
52 mins); and SNT (61%, 33:1 mL/g, 100 W and 65 mins). The extraction yields obtained
under their respective optimal extraction parameters were as follows: 12.9 (SMT), 12.2
(GMT), 15.0 (WPT) and 16.5% (SNT). It is interesting for industries to note that different
ultrasound-assisted extraction parameters are required when different grades of white tea

Published: January 2024

Purpose: The aim of the research is to estimate the production and marketing efficiency of okra under the protected agriculture system and to identify the most important production and marketing problems.

 

Theoretical Framework: The least squares method OLS was used to estimate the parameters of the short-term

cost function using the statistical program SSPS, and the short-term cubic cost function was adopted.

 

Design/Methodology: Data were collected through a questionnaire form for a random sample of 62 farmers of the covered okra crop in Baghdad Governorate (Mahmoudiya District) for the season 2022-2023, to measure the production and marketing efficiency of okra under the protected agriculture system.

 

Findings: There is economic efficiency in the production of okra, the ratio of return to costs is greater than one, while the production costs function indicated that the crop does not achieve the required level of efficiency, as the optimal volume of production was about 12.22 tons. the average production volume of the selected sample was about 4.3 tons, and the estimated results also indicated that the total cost about 23350570 ID, and the marketing efficiency of the crop about 85%.

 

Practical and Social Effects: The study benefits okra farmers through knowledge of the optimal use of available resources, i.e. the production of the largest amount of goods and services using the elements of production available, exploiting the resources available to it to produce goods and services that specialize in its production, farmers achieve marketing efficiency through maximizing the ratio between outputs and inputs.

 

Value or Origin: The agricultural sector in Iraq is of great importance among other economic sectors. Meanwhile, it faces many challenges, including population increase, limited land and water resources, inefficient use of available resources, and lack of the seasonality of agricultural production coincides with the periods required for consumption, which makes the transition to protected agriculture necessary to increase agricultural production as one of the means of agricultural intensification to increase agricultural production to meet the increased demand for crops. Therefore., studying marketing efficiency is one of the important studies, as it is the main factor for continuing to deal in the production and of any crop or not.

Published: January 2024

A seca é um evento natural recorrente,e sua avaliação é primordial em locais suscetíveis, a citar a região do MATOPIBA, um acrônimo dos quatro estados que a compõe (Maranhão, Tocantins, Piauí e Bahia), a qual vem sendo bastante explorada. Portanto, objetivou-se através deste trabalho identificar e compreender a variabilidade espaço temporal de eventos de secas meteorológicas ocorridas nas microrregiões pertencentes ao MATOPIBA através de técnicas de análise de serie temporais. Utilizou-se séries de dados históricos mensais de precipitação e temperatura do ar para o período de 1961 a 2018 provenientes das reanálises do CRU-TS-4.03. A caracterização da seca se deu através do Índice Padronizado de Precipitação e Evapotranspiração-SPEI, especificamente o SPEI com incidência de doze meses (SPEI-12), o qual caracteriza uma interface da seca meteorológica. As microrregiões com características homogêneas do SPEI-12 foram obtidas por meio da análise de agrupamento, assim como aplicação dos testes não-paramétricos de Mann-Kendall e Sen’s e de homogeneidade de Pettitt para verificar os padrões temporais para a região. Desse modo, através da variabilidade das secas na região foi possível observar o aumento progressivo de intensidade e magnitude desse evento em toda a região, com ênfase nos períodos mais recentes. Além disso, constatou-se que o grupo mais seco foi o Grupo 5, o qual engloba grande parte do estado do Tocantins (com exceção de três micros) e uma microrregião do extremo sul maranhense. Em contrapartida, destaca-se o Grupo 1 como o mais úmido do período analisado, o qual abrange o sudoeste do Maranhão e norte do Tocantins. Quanto às análises de tendências, identificou-se que todas as micros analisadas apresentaram tendências decrescentes significativas, acarretando no aumento dos eventos de secas na região durante os anos avaliados.Palavras-chave: Índice de precipitação e evapotranspiração, variabilidade, agrupamento, tendência.

Em um sistema urbano historicamente desigual como o de Recife, diferentes realidades hídricas se sobrepõem para a construção da cidade anfíbia. Nesse sentido, mesmo a água sendo um elemento abundante na paisagem recifense, as pessoas estabelecem relações distintas, a depender do território que está inserida e a classe social a que pertence. Assim sendo, objetivou-se com este artigo discutir as desigualdades socioterritoriais da cidade do Recife a partir da relação entre a população e os corpos d’água. Para tanto, realizou-se uma pesquisa bibliográfica que abarcou a compreensão do território recifense e a interação dos indivíduos com a natureza, bem como visitas in loco de forma a subsidiar e elucidar as análises teóricas.

The knowledge of the spatial variability of soil attributes has been characterized as an important step for an adequate management to be carried out. Thus, the aim of this study was to evaluate spatial variability of soil resistance to penetration in areas under forest and converted to agricultural uses in the Amazon, Brazil. The study was carried out in Typic Hapludultsin the San Francisco Settlement located in the municipality of Canutama, Amazonas, Brazil. Four areas were selected. The collections proceeded at the crossing points of the grids, under the layers of 0.00-0.05; 0.05-0.10; and 0.10-0.20 m, making a total of 80 sample points in each area. Physical soil analyzes were carried out, with the criterion of determining the texture, soil resistance penetration and soil moisture. The variation in soil moisture content remained constant in all evaluated layers. The PR and soil moisture showed a spatial dependence structure that made it possible to analyze the influence on the different conditions of use and evaluated layers, since the scope of spatial dependence was preponderant to evaluate the scales of spatial variation, mainly in verifying the possible effects and factors that most affect these variables analyzed.

No município de Belém, capital do estado do Pará, encontra-se os Lagos Água Preta e Bolonha, utilizados como fonte de fornecimento de água para parte da população da Região Metropolitana de Belém (RMB). Apesar da importância destes mananciais, a área da bacia do rio Murucutu encontra-se antropizada, principalmente devido aos impactos causados pelo crescimento urbano. Partindo dessa premissa, este trabalho teve por objetivo realizar um levantamento bibliográfico referentes a qualidade da água dos Lagos Água Preta e Bolonha, e compreender como as ações humanas comprometem a manutenção desses recursos. Para a execução do estudo, realizou-se uma revisão bibliográfica em publicações científicas, nacionais e internacionais, indexada nas bases de dados SCIELO e Google Acadêmico, entre o período de 2011 e 2022. Foram encontrados 17 trabalhos referentes à temática proposta e pode-se notar que os lagos são fundamentais para o abastecimento público da RMB, nos entanto, próximo aos lagos bacia estão localizados vários bairros que causam pressão urbana em seu entorno, situação que causa diversos problemas, tanto sociais quanto ambientais. Falta ainda dados de um programa de monitoramento das águas dos lagos. Contudo, apesar dos fortes impactos ambientais descritos na literatura, os lagos ainda conseguem manter o abastecimento da região.

A ruptura em série de barragem pode gerar danos catastróficos para a população localizada a jusante e ao meio ambiente. Diante disso, o presente estudo tem como objetivo fazer uma análise entre os resultados gerados pela ruptura hipotética em cascata de quatro barragens situadas na cidade de Caruaru-PE. Foram realizadas três simulações hidrodinâmicas, com a finalidade de prever se o rompimento de uma das barragens em análise resultaria no rompimento em cascata dos barramentos a jusante. Além disso, foram comparados os hidrogramas de ruptura calculados através dos softwares HEC-HMS e HEC-RAS, utilizados para gerar os mapas de inundação a fim de analisar as potenciais áreas atingidas. A metodologia foi baseada em: descrição da área de estudo como características técnicas da barragem, desenvolvimento do hidrograma de ruptura por meio do software HEC-HMS 4.8 e simulação de ruptura nos três cenários analisados, através do software HEC-RAS 6.2. Foi constatado, por meio das modelagens hidrodinâmicas, que nos três cenários, o rompimento da barragem a montante geraria o rompimento em cascata do barramento a jusante. Também foi possível concluir que as vazões de rupturas, obtidas com a simulação do HEC-HMS são maiores que as obtidas com o HEC-RAS. Além disso os mapas de velocidade, profundidade e intensidade apresentaram manchas semelhantes no primeiro e segundo cenário para os níveis de perigo e o terceiro cenário níveis mais altos. Almeja-se com os resultados encontrados, auxiliar na elaboração de medidas mitigadoras para minimizar os danos gerados pelo eventual rompimento das barragens em estudo.

This study investigated the potential influence of artificial nocturnal lighting (ALAN) on the diet and behavior of the owl Tyto furcata in the Caatinga biome, northeastern Brazil, from 2016 to 2021. The diet of T. furcata was compared between two adjacent areas, the National Park (PARNA) Furna Feia and the urban area of the municipality of Mossoró, a semiarid region of the west of the State of Rio Grande do Norte, with different ALAN intensities. The analysis of the geographic information system (GIS), using night images from the SNPP and NOAA-20 satellites, identified that ALAN in PARNA Furna Feia was absence, while in the urban perimeter of Mossoró, ALAN was present. The diet of T. furcata owls at PARNA Furna Feia comprised mostly of bats and nocturnal rodents captured at night under rocks and caves. In the urban area of Mossoró, the diet consisted mainly of diurnal birds and rodents captured during the night, when they rested in roosts under ALAN. Thus, urbanization affects the foraging behavior and diet of this bird of prey in Caatinga. ALAN appears to be one of the environmental conditions that T. furcata favors in urban habitats in the Caatinga biome, as it allows nightly hunting under artificial lighting of birds aggregated in roosts.

As interações entre formigas e plantas ocorrem em redes ecológicas dinâmicas e complexas. A riqueza presente nessas relações atrai a comunidade científica na tentativa de compreender a estrutura dessas redes. Essa pesquisa teve como objetivo identificar as espécies de formigas em inflorescências de espécies arbóreas em uma área de savana no município de Vigia, estado do Pará. Foram selecionadas seis espécies arbóreas e para cada espécie foram selecionados 10 indivíduos em fase de floração. Os dados foram coletados quinzenalmente durante o período diurno de outubro/2021 a setembro/2022. O material coletado foi transportado para o Laboratório de Ciências da Terra e Ecologia do Museu Paraense Emílio Goeldi para posterior identificação em nível de gênero e espécie. As formigas registradas nas seis espécies arbóreas totalizaram 1.010 indivíduos em onze espécies, destacando-se Camponotus crassus em todas as espécies arbóreas e Nesomyrmex spininodis e Solenopsis sp. exclusivas de uma espécie. A composição de formigas dominantes visitando flores em uma savana na Amazônia Oriental foi similar as espécies mais comuns de formigas que visitam plantas na área central de distribuição do Cerrado.

Translator   Solos arenosos que ocorrem próximo a centros urbanos são impactados pela atividade exploratória da mineração. No Amazonas essas áreas estão associadas a Campinaranas, cuja fragilidade do ecossistema torna importante a ampliação de conhecimento para compor planos de restauração eficientes. O objetivo deste estudo foi caracterizar e classificar solos arenosos sob Campinaranas de dois municípios da região metropolitana de Manaus. Foram selecionadas cinco áreas em Manaus e Presidente Figueiredo, onde perfis foram abertos para caracterização morfológica, química, física e mineralógica do solo. Os perfis 01, 02 e 03 foram classificados como Neossolo Quartzarênico Órtico típico, o Perfil 4 como Espodossolo Humilúvico Órtico dúrico e o Perfil 5 como Neossolo Quartzarênico Órtico espodossólico. Os solos analisados apresentaram consistência solta a muito friável, com textura variando de franco arenosa a areia. Os teores de argila foram baixos, resultando em baixa densidade e alta porosidade. A acidez variou de fortemente ácida à extremamente ácida, com maiores concentrações de H+Al e Al3+ nos horizontes superficiais. O carbono orgânico total apresentou maiores concentrações nos horizontes superficiais e no horizonte Bh do P04. A capacidade de troca de cátions efetiva e total também foram maiores em superfície e nos horizontes Bh (P04) e C4 (P05). Em relação a mineralogia, foram encontradas maiores proporções de formas cristalinas de Al2O3 e Fe2O3 em comparação com as formas amorfas, principalmente no Bh (P04) e em agregados de matéria orgânica no P03, evidenciando o processo de podzolização e a influência do Al na formação desse solo.
