Analysis of Ecological Agriculture from the Perspective of Maintaining the Biodiversity of Agricultural Lands
Authors: Sandu Mariana , Strateanu Amalia Gianina , Udrea Lavinia
Published: November 2023

The intensification of agriculture, the specialization of production and the use of a wide range of agrochemicals has led to the loss of biodiversity on agricultural land, namely the cultivation of a small number of high-yielding varieties and short crop rotation. The loss of biodiversity and the homogenization of crops directly affects the productivity of agroecosystems and implicitly the sustainability of food systems.

In this context, the article proposes an analysis of the evolution of ecological agriculture from the perspective of the need for a change in the structure and operation of agriculture to restore the biodiversity of agricultural land. The analysis is oriented towards the economic, social and environmental aspects given the fact that, often, ecological agriculture is proposed as a solution to ensure the food security of the world’s population.

The analysis of data on global organic agriculture indicates that, in 2021, the total area of agricultural land cultivated in the organic system represented approximately 1.6% of the total agricultural land, the number of producers registered in organic agriculture reached approximately 3.7 million and the global market for organic products reached 125 billion euros.

With regard to organic agriculture in Romania, in 2021, the total area cultivated in an ecological system was 578.7 thousand ha (3.2% of agricultural land cultivated organically in the EU), and the number of economic operators was 12,231.

Given that the productions obtained in the ecological system are 20-40% lower than those in conventional agriculture, the integration of ecological practices in agriculture has the potential to increase the productions obtained and maintain biodiversity on agricultural land.

Authors: Ciornei Laurentiu , Strateanu Amalia , Udrea Lavinia
Published: November 2023

The actual economic development is increasingly conditioned by the environment and resources. Reducing the impact of human activities on the environment and decreasing the pressure on natural resources are requirements that can be achieved by adopting a circular economy, in order to replace the economy based on a linear process of production and consumption. The concept of circular economy is strongly used, both in Europe and worldwide, but, apart from a few practical models, the rest is limited to ideas and concepts. The aim of this article is to enhance to the scientific research of the circular economy and its impact on the mountain economy, especially on biodiversity. First of all, this article will focus on the definition of the circular economy, from the point of view of the sustainable development of the mountain area in Romania, and, secondly, this paper adopt a critical analysis of the concept, from the perspective of biodiversity. Considering that there are a lot of theories on the international level that argue and prove the potential of the circular economy, we refer to a few national models of circular economy, as landmarks, to support its application in the Romanian mountain area.

Published: November 2023

Vegetables are especially important in human nutrition. Rational nutrition is unimaginable without the daily use of various varieties of vegetables. Green vegetable plants are important for every family that has a garden. This category includes several vegetables, such as: spinach, salad, green garlic, loboda, green onions, etc. Perennial greens should be grown in a marginal area, so as not to create problems when preparing the soil for other crops. From the salad category, Lettuce is the most widespread, it is cultivated for its heads and leaves, which can be eaten in salads, it is also eaten raw, especially when other vegetables on the market are missing. Lettuce is an annual plant with a main pivoting root, leaves full of fleshy and thin vitamins, but it is also a herbaceous plant. It is part of the Compositae family. Following the completion of research on the behavior of eight lettuce varieties grown in solarium on different vegetation cycles, at the Ulmi Variety Testing Center we performed the determination of parameters that influence the quality of lettuce production from which the following measurements are derived: plant height, average weight of plants at harvest, leaf embossing, dry substance, leaf thickness, plant diameter, the shape of the head and variety color. The present paper aims to determine some parameters that influence the quality of salad production. Eight lettuce varieties grown in the solarium were monitored at the Ulmi Variety Testing Center. The parameters followed in the study were: plant diameter (cm), plant weight (g), leaf thickness (mm), embossing size (cm), height of flowering plants (cm) and soluble dry matter.

Published: November 2023

Hingga saat ini, kecelakaan pesawat udara masih tidak bisa dihindari meskipun telah didukung dengan kemajuan teknologi aeronautika dan adanya ramalan cuaca. Kecelakaan dalam penerbangan dapat berakibat fatal sehingga menimbulkan kekhawatiran. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang berperan dalam kejadian kecelakaan pesawat udara di Indonesia melalui pendekatan the shell model. Penelitian ini menggunakan analisis deskriptif dengan metode kualitatif melalui wawancara mendalam dengan informan penelitian dan melakukan telaah literatur. Komponen yang diteliti, berdasarkan the shell model, meliputi faktor manusia, mesin, standar/prosedur, dan lingkungan. Literatur menyebutkan bahwa kecelakaan pesawat udara di Indonesia paling banyak disebabkan oleh faktor manusia (67,12%). Namun, hasil penelitian menunjukkan bahwa kecelakaan pesawat udara di Indonesia tidak disebabkan oleh faktor tunggal, melainkan faktor-faktor lain yang saling mempengaruhi sehingga mengakibatkan kecelakaan. Faktor-faktor tersebut adalah faktor manusia, mesin, standar/prosedur, dan lingkungan yang saling berhubungan satu sama lain sehingga membentuk komponen-komponen penting dalam penerbangan. Terjadinya ketidakseimbangan pada salah satu komponen tersebut dapat mempengaruhi komponen lainnya sehingga dapat mengakibatkan kegagalan dalam penerbangan. Kesalahan pilot bukan merupakan satu-satunya penyebab terjadinya kecelakaan, melainkan adanya faktor-faktor lain yang turut andil dalam kejadian tersebut. Beberapa temuan yang diketahui turut andil dalam terjadinya kecelakaan pesawat udara adalah penumpang yang tidak mematuhi standar keselamatan di dalam pesawat udara, seperti tidak menonaktifkan handphone atau mengubah ke mode pesawat udara, penggunaan mesin pesawat udara yang lama dengan alasan masih layak pakai padahal mesin dan pesawat udara telah ditentukan batas waktu penggunaannya, faktor personal atau pekerjaan pilot itu sendiri, dan cuaca buruk.

Authors: Oliveira Weslley Rodrigues , Rosário Flavio Jean do , Murta Camila Bicalho , Yamamoto Gustavo Pimenta , Cenachi Adriana Regina Campolina
Published: November 2023

Objetivo: Realizar análise com o propósito de investigar a associação entre a cobertura das vacinas conjugadas e fatores de risco para morbimortalidade na doença pneumocócica invasiva (DPI), a fim de avaliar novas abordagens de prevenção. Revisão bibliográfica: No Brasil, a presença das vacinas conjugadas para pneumococo tem papel substancial na redução da incidência e da morbimortalidade de DPI na população, principalmente pela alta incidência do subtipo 11. Entretanto, esses indivíduos têm maior risco de contrair DPI causada por sorotipos não cobertos (PCV13 e PPV23). Isso destaca a necessidade de futuras vacinas conjugadas se adequarem a novas cepas. Fatores que influenciam na mortalidade: uso prévio de antibióticos, antibiótico inadequado no tratamento inicial, resistência microbiana e o uso de vancomicina. O uso de penicilina ou amoxicilina foi visto como fator protetor. Considerações finais: A vacina conjugada PCV13+PPV23 mostra-se imperativa para redução da morbimortalidade. Entretanto, a crescente incidência dos sorotipos 19A e 6A ressalta a necessidade de nova vacinação. Uso prévio de antibióticos mostrou relacionar-se com piores desfechos. O diagnóstico e início precoce do tratamento são fatores protetores e modificáveis.

Published: November 2023

Objetivo: Revisar os aspectos clínicos da endocardite infecciosa e descrever as atualizações dos critérios de Duke. Revisão bibliográfica: A endocardite infecciosa é uma inflamação nas válvulas cardíacas causada por infecção por microrganismos, principalmente bactérias, sendo a principal causa de infecções cardíacas. Fatores de risco, como uso de drogas injetáveis e cirurgia valvar, aumentam a suscetibilidade. Essa condição pode levar a complicações crônicas, incluindo insuficiência cardíaca, além de possuir uma taxa de mortalidade hospitalar de 15-20%, podendo chegar a 30% nos primeiros 30 dias. Em 2023, a Sociedade Internacional de Doenças Infecciosas Cardiovasculares atualizou os critérios diagnósticos, incluindo novos microrganismos para melhorar a sensibilidade do diagnóstico. Além disso, houve a inserção do critério cirúrgico a fim de facilitar o diagnóstico. Considerações finais: As modificações nos Critérios de Duke em 2023 buscam melhorar a investigação e padronização do diagnóstico para intervenções direcionadas precoces e precisam ser divulgadas e discutidas para melhorar os prognósticos dos pacientes.

Physical activity levels and sleep quality among military aircrew during COVID-19: A questionnaire-based pilot study
Authors: Guru Chandra Sekara , Murtaza Murtaza , Mahajan Uma
Published: November 2023

Objective:

Adequate physical activities (PAs) and sleep quality are also crucial factors for maintaining optimal performance in military aircrew given the physiological demands of alien flying conditions and the occupational stress of the military lifestyle. During the COVID-19 pandemic, PA levels and sleep quality are compromised globally. Due to a lack of adequate research studies, this pilot study was aimed at assessing the PA levels and sleep quality among military aircrew during the COVID-19 pandemic.

Material and Methods:

Fifty-nine aircrew (Weight: 68.7 ± 6.45 kg and body mass index: 22.6 ± 1.76 kg/m2) of a training establishment voluntarily participated in this anonymous pen-paper pilot survey. The participants included instructors/trainee aircrew and one female aircrew. Responses for the validated International Physical Activity Questionnaire, Pittsburgh Sleep Quality Index (PSQI) questionnaire, and self-rating before the pandemic along with demographic details were collected. Data were expressed as a median and interquartile range with statistical significance set at 0.05.

Results:

About 80% of participants reported participating in games and PA regularly. Before the pandemic, 68% of aircrew did moderate-vigorous PA and >93% had average-good sleep quality. Total PA during the pandemic was 1059 (594, 1074) MET-min/week with an energy expenditure of 1226.48 (623.7, 2036.7) Kcal/week. Time spent sitting was 6 (5, 10) h/day and more than 86% of aircrew reported good global PSQI score. The effect of the pandemic was observed as significantly reduced energy expenditure, that is, 1001.25 (673.2, 1794) Kcal/week among aircrew who self-rated high levels of PA before the pandemic (P= 0.042). Aircrew who regularly played games significantly engaged in more total PA of 1547 (827, 1911) MET-min/weeks (P< 0.0001) with a significantly higher energy expenditure of 1752.7 Kcal/week (P< 0.0001).

Conclusion:

Despite pandemic restrictions, aircrew who were regularly involved in PA/games were able to maintain a better PA level. Moreover, aircrew with better sleep quality significantly engaged in higher PA levels and lesser sitting time. Sedentary behavior was assessed as sitting time increased in trainee aircrew, aircrew who were not involved in active flying, and aircrew with bad sleep quality.
A rendszeres testedzés hatására kialakuló kardiális változások dinamikája

Published: November 2023

A rendszeres, intenzív fizikai aktivitás hatásait a sportkardiológia számos kutatása tanulmányozta: mind a kardiovaszkuláris prevencióban betöltött szerepét, mind az élsportolók esetén a testedzés kiváltotta miokardiális hipertrófiát, a sportszívet részletesen jellemzi az irodalom. Ebben a rövid áttekintésben összefoglaljuk a hosszú távú, rendszeres edzés által kiváltott kardiális adaptáció kialakulásának, és a sportolás felfüggesztése utáni visszafejlődésének ütemét, a szakirodalomban leginkább leírt három fő aspektus (morfológia, funkció, elektromos tulajdonságok) figyelembe vételével. Míg a legtöbb sportkardiológiai tanulmány egészséges kontrollokhoz hasonlította az élsportolók adatait egy adott időpontban, mi az utánkövetéses (longitudinális) eredményekre fókuszáltunk, amelyek alapját a sportolók rendszeres edzés és/vagy az edzés felfüggesztése előtti, saját adatai képezték. Az intenzív fizikai edzés már körülbelül 2 hét után szignifikáns kardiális funkcionális javulást váltott ki, míg a sinus bradycardia és bal kamrai hipertrófia első jelei általában 2 hónap edzés után mutatkoztak. Ezen változások hasonló tendenciáját korábbi kisállatmodelles kísérletek során is megfigyelték. Mind a humán, mind a kísérletes eredmények szerint az edzés felfüggesztését gyors morfológiai, funkcionális és elektromos regresszió követi. Az eredmények arra utalnak, hogy az edzés kiváltotta kardiális funkcionális javulás (korai diasztolés funkció, maximális oxigénfelvétel) korábban megjelenik, mint a morfológiai és elektromos változások. Az eredmények azt sugallják, hogy a kardiális funkcionális javulás lehet a sport elsődleges következménye, míg a morfológiai és elektromos változások a szív és a szisztémás keringés rendszeres hemodinamikai terhelésének másodlagos következményei lehetnek. Az edzés okozta eltérések a kialakulásukhoz képest gyorsabb ütemben fejlődnek vissza.
A kardiovaszkuláris esemény utáni betegek irányelvek szerinti lipidcsökkentő kezelésének lehetőségei Magyarországon 2023-ban: a fixkombináció prioritása
Authors: Márk László , Nagy Mária , Papp Viola
Published: November 2023

Lipidológiai alaptétel, hogy minél nagyobb a kardiovaszkuláris kockázat, annál nagyobb nyereség érhető el, ezért lenne nagy jelentősége az akut koronáriaszindrómán (ACS) átesett betegek irányelvek szerinti kezelésének. Ennek ellenére magyarországi vizsgálatok, valamint a multinacionális DaVinci és SANTORINI-tanulmányok is csupán 20% körüli 1,4 mmol/l LDL-koleszterin- (LDL-C) célérték elérést igazoltak. Ennyi lenne a napi gyakorlat során az elérhető maximum? Nyilvánvalóan nem. A svéd infarktusregiszter, a SWEDEHEART eredményei szerint az ACS utáni betegek második követéses vizsgálata során az 1,4 mmol/l célérték elérése 2020-ban 41%, 2021-ben 52%, 2022-ben pedig 56% volt. Ebben a nagy intenzitású statinok adásán kívül annak lehet a legnagyobb szerepe, hogy az ezetimib adása az évek során egyre gyakoribbá vált, 2022-ben meghaladta az 50%-ot. Az ezetimib alkalmazásának fontosságát támasztják alá újabb klinikai vizsgálatok is, valamint egy új szakértői állásfoglalás, amely szerint a statin és ezetimib kombináció már az igen nagy kockázat megállapításakor elsővonalbeli kezelésként elindítandó. A statin és ezetimib fixkombinációs adása 87%-kal javítja az adherenciát a kéttablettás adagoláshoz képest. Kedvezőbb adherencia esetén kevesebb kardiovaszkuláris esemény várható.

Electrochemically mediated amine regeneration (EMAR) is emerging as a promising electrochemical approach for carbon capture from point sources. In this study, for the first time, the absorbent chemistry of the EMAR process was revived by considering criteria beyond metal-amine complexation. The systematic investigation focused on using secondary amines, which were previously overlooked in EMAR due to limited metal-amine interaction, despite their proven effectiveness in conventional carbon capture processes. The integration of secondary amines— monoethanolamine (MEA), aminomethyl propanol (AMP), and methyldiethanolamine (MDEA)—with the benchmark ethylenediamine (EDA) was thoroughly studied, evaluating their impact on absorption and desorption kinetics and capacities, and electrochemical performance. Among the blends, EDA+MDEA emerged as the top performer, particularly excelling in electrochemical aspects. The charge transfer resistance (RCT) of the deposition reaction, as the rate-limiting step, for the EDA+MDEA blend was reduced by 40% compared to pure EDA, and the heterogeneous electron transfer rate constant (k0) improved threefold. In the bench-scale assessments, the EDA+MDEA blend showed a notable decrease in desorption energetics to 37 kJ/molCO2, marking a 34% reduction compared to the 56 kJ/molCO2 required for pure EDA. This marks the lowest reported energetics for an EMAR process targeting point source carbon capture. This research paves the way for future systematic investigations of a wider range of amine blends for EMAR and eventually the process implementation at larger scales.

Steam adsorption equilibrium data is important for many carbon capture applications, including direct-air capture, point-source, and pre-combustion carbon capture. However, there is a dearth of concentrated unary equilibrium data for H2O at temperatures greater than 100°C. In this study, unary steam adsorption equilibrium data was measured at 110°C and up to approximately 1.0 bar partial pressure with a steam microscale dynamic column breakthrough (μDCB) apparatus using a milligram quantities of adsorbent. These partial pressures are equivalent to those used in industrial carbon capture processes. The construction of the apparatus is detailed, along with the necessary calibrations and validations to ensure accurate equilibrium measurement. Three adsorbents were considered in this study: an activated carbon (Calgon BPL), an amine-functionalized polymer (Lewatit VP OC 1065), and a metal-organic framework (CALF-20). It was observed that steam adsorbs strongly on all three materials at 110°C. Activated carbon and Lewatit displayed type-3 isotherm shapes, and CALF-20 displayed a type-5 isotherm shape. Activated carbon and Lewatit were modeled with the GAB isotherm, and CALF-20 was modeled with the cubic-Langmuir isotherm. The 110°C data was compared against H2O equilibrium data collected at 25°C as a function of relative pressure. An in-house dynamic column breakthrough simulator coded in MATLAB was able to predict the μDCB composition breakthrough curves well for all three materials. The data obtained from the steam breakthrough experiments has important process implications and highlights the need to measure steam adsorption data for any proposed carbon capture material.

An enormous value proposition exists when molecules like acetic acid and methanol are derived from natural gas. With abundant worldwide resources, methane to methanol (M2M) by partial oxidation or acetic acid through C-insertion is considered one of the catalysis's most enterprising chemical transformations. In this work, significant catalytic challenges successfully tackled are the continuous partial oxidation of methane to methanol and acetic acid at atmospheric pressure. In continuous flow and at atmospheric pressure, a modified silica-supported bimetallic (AuFeHS) catalyzed methane to methanol using H2O2 with an impressive yield of 224 mmol/gFe+Au. Co-feeding CO in the stream produces acetic acid, demonstrating a selectivity switch from methanol with an overall yield of 92 mmol/gFe+Au.

Published: November 2023

Dive into the colourful realm of textile wastewater, where α-Fe2O3 attached carbon material, born from the corn husk (Fe-AC@CH), emerges as an eco-hero in the battle against cationic dye pollution, starring Methylene Blue (MB) and Malachite Green (MG). Our journey ventures deep into the synthesis and structural mysteries of Fe-AC@CH, unravelling its secrets through a high-tech arsenal: Fourier-Transform Infra-Red (FT-IR), X-ray diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Field Emission Scanning Electron Microscopy (FESEM), High-Resolution Transition Electron Microscopy (HRTEM), and Raman Spectroscopy. In the quest for optimal adsorption, we meticulously dissect the variables — adsorbent dose, contact time, solution pH, initial dye concentration, and temperature — orchestrating the perfect conditions for MB and MG removal. Isothermal revelations spotlight the Langmuir and D-R isotherm models as the guiding stars, while kinetic analyses unveil the captivating dance of the pseudo-first-order model, boasting stellar correlation coefficients (R2) and perfect harmony with experimental sorption capacities (Qe). Enter the realm of MG, where the intraparticle diffusion kinetic model adds another layer to our understanding, seamlessly aligning calculated Qe values with experimental results. The grand finale reveals physisorption as the masterstroke governing the enchanting adsorption narrative of both MB and MG onto the Fe-AC@CH composite. This ground-breaking study not only anoints Fe-AC@CH as the stalwart defender against cationic dyes in textile wastewater but also heralds corn husks as sustainable sorcery, conjuring eco-friendly adsorbents. The results, a treasure trove of insights, navigate the intricate interplay between composite structure, adsorption kinetics, and isothermal behavior, ushering in a green revolution in the removal of cationic dyes from our waterways.

É consenso que o conhecimento é pressuposto fundamental para preservação de qualquer bioma. Entretanto, um a cada três adolescentes não sabe informar em que bioma vivem, sendo uma informação bastante preocupante quando pensamos na preservação da biodiversidade para as futuras gerações. O objetivo principal deste estudo é investigar se essa proporção é a mesma na região do semiárido da Paraíba e avaliar o conhecimento e a percepção de estudantes do ensino médio integrado ao técnico em agropecuária sobre o bioma Caatinga. Os dados foram coletados através de um formulário, contendo 13 questões objetivas e discursivas, aplicado a 77 alunos do primeiro ano. Dentre eles, cerca de 53% afirmaram que vivem no bioma Caatinga, superando a média nacional. Os discentes citaram plantas e animais nativos do bioma; espécies introduzidas, exóticas ou domesticadas foram frequentemente relatadas (ex.: nim e boi). Infelizmente, nenhum estudante já esteve em uma Unidade de Conservação, mas os estudantes citaram várias formas de preservação e conservação da Caatinga, como não provocar queimadas, não poluir os rios e não desperdiçar alimentos. Os alunos ilustraram a paisagem do bioma Caatinga com poucos elementos, além de outros que carregam uma visão negativa do bioma. Todo o conteúdo trabalhado no questionário foi dialogado em uma roda de conversa, que trouxe a explicação de vários conceitos e elucidou dúvidas dos entrevistados.

Reflexões sobre a morte, o luto e a emoção no contexto pandêmico: entre os olhares de Norbert Elias e Mauro Koury
Authors: Paz ALmeida Alexandre
Published: November 2023

Este artigo apresenta contribuições teóricas sobre o fenômeno do luto, da morte e das emoções como parte das reflexões desenvolvidas por Koury (2003, 2004, 2005), pioneiro na consolidação teórica e metodológica de pesquisas em Antropologia e Sociologia das Emoções no Brasil, analisando as inter-relações entre emoções, indivíduo e sociedade, principalmente na contemporaneidade urbana brasileira. O tema do luto e da morte foi trabalhado enquanto recorte para pensar os processos de mudança comportamental entre a ideia de sociedade tradicional e relacional, para padrões mais individualizados e intimistas, experienciados por classes médias e populares de cidades do Brasil. O artigo também teceu considerações sobre a influência que Norbert Elias pareceu desenvolver no pensamento de Koury e suas formulações conceituais a respeito da vergonha, embaraço, autocontrole, entre outros, fundamentais no olhar de Koury (2003) em relação à formação de um ser discreto.
