Published: September 2024

A cobrança pelo uso de recursos hídricos pode ser entendida como uma forma de incentivar o uso racional da água, arrecadando recursos financeiros para investimentos em ações de recuperação e conservação ambiental. Diante disso, objetivou-se analisar a cobrança pelo uso da água na bacia hidrográfica do rio São Francisco (BHSF) entre os anos de 2011 e 2020. Para tanto, realizou-se um levantamento bibliográfico de pesquisas oriundas de trabalho de mestrado e de doutorado relacionadas ao estudo dos recursos hídricos, artigos científicos, legislações, planos de aplicação, relatórios de gestão, deliberações e informações sobre a cobrança da água, arrecadação e projetos executados na BHSF, nas páginas eletrônicas do Comitê de Bacia Hidrográfica do rio São Francisco e da Agência de Bacia Peixe Vivo. Com os resultados, notou-se que a cobrança na referida bacia hidrográfica está alcançando, de forma efetiva e institucional, os seus objetivos. Os recursos disponíveis não são suficientes para atender às demandas de investimentos necessárias para mitigar os principais desafios da bacia hidrográfica. Observou-se, também, que houve constante aumento na arrecadação de recursos, provenientes de usos diversos da água, entre os anos de 2011 e 2018, assim como um crescimento expressivo da cobrança com a nova metodologia iniciada no ano de 2019, principalmente para irrigação e transposição. Apesar dos esforços e do comprometimento dos órgãos gestores do rio São Francisco, a enunciada bacia hidrográfica enfrenta obstáculos expressivos, marcados pela elevada demanda pelo uso de recursos hídricos, assim como a distribuição irregular das ações de recuperação na bacia hidrográfica.

Published: September 2024

O crescimento da produção mundial de plásticos tem levado ao aumento desses resíduos nas praias como consequência do descarte inadequado. Esse estudo avaliou os resíduos plásticos coletados em seis praias (Artistas, Atalaia, Cinelândia, Robalo, Refúgio e Viral) situadas na cidade de Aracaju, estado de Sergipe, Nordeste do Brasil. Foram realizadas duas coletas em cada praia no período de outubro de 2023 a abril de 2024, na faixa de areia (FA) e faixa de vegetação (FV). A área de coleta foi delimitada em 2.000m2 a partir do limite da preamar no sentido costa, para FA e a partir do início da vegetação no mesmo sentido, para FV. Foram coletados 2.823 itens, equivalente a 22.298g distribuídos nas FA e FV. A quantidade em massa (12.544g) foi maior na FV. Não houve diferença entre as quantidades de itens encontrados entre as FA e FV. A praia do Viral apresentou maior quantidade em massa (8.943g), enquanto a Cinelândia, a menor (1.147g). Em relação aos itens, as maiores quantidades foram encontradas na Atalaia (590) e Refúgio (572) e a menor na Cinelândia (299), predominando fragmentos, embalagens e copos. A classificação revelou que o poliestireno - PS (23,7%) e polietileno de alta densidade - PEAD (20,6%) foram os mais prevalentes. Os resultados demonstram a necessidade de políticas públicas que tratem especificamente sobre o assunto a exemplo de campanhas educativas sobre o uso consciente dos plásticos e seu descarte adequado.

O presente trabalho tem por objetivo propor uma metodologia para subsidiar o futuro processo de enquadramento dos cursos d’água superficiais da bacia do rio Piauitinga, baseada na aplicação concomitante da modelagem de qualidade da água e das curvas de permanência de qualidade. Foram estabelecidas duas condições para simulações da qualidade da água, sendo a condição atual com eficiência de 0% e a segunda considerando eficiência de 70% de remoção de demanda bioquímica de oxigênio (DBO), considerando os cenários de ocorrência e não ocorrência de autodepuração, para o ano de 2024. As cargas totais de DBO5,20 foram estimadas nas ottobacias da bacia, no nível 6, considerando-se o esgotamento doméstico e efluentes industriais como fontes poluidoras. Através do modelo QUAL-UFMG, foram simulados os perfis de DBO5,20 e de Oxigênio Dissolvido (OD) ao longo do rio Piauitinga. As curvas de permanência de qualidade para o parâmetro DBO5,20 foram construídas para rio de água doce, classes 1, 2 e 3. A capacidade de autodepuração do rio Piauitinga permitiu a redução acima de 25% da carga total de DBO5,20, indicando a necessidade de ampliação da cobertura do serviço de tratamento de esgotos na área de estudo. Os resultados demonstram que a metodologia adotada se mostrou adequada para auxiliar o processo de enquadramento de corpos d’água.
Urine analysis in monoclonal gammopathies at diagnosis: settling cut-off values
Authors: Vidal-Pla Mònica , Nuez-Zaragoza Elisa , Bhambi Indira , Aguadero Vicente
Published: September 2024

Objectives

Laboratory testing has an extensive role in the diagnosis of monoclonal gammopathies. Since the last updates of the International Myeloma Working Group (IMWG) guidelines for the diagnosis of monoclonal gammopathies, debate has arisen as to whether urine analysis remains relevant for the diagnosis of these entities.

Methods

We carried out a retrospective study with data from 132 patients with a newly diagnosed serum M-protein. Patients were divided into two groups depending on the presence of M-protein in urine and different variables were recorded and statistically compared between groups.

Results

The aim of the study was to find a serum M-protein cut-off value under which urine analysis could be avoided in the first laboratory diagnosis. The results show that when the concentration of serum M-protein is ≤3.5 g/L and eGFR is >30 mL/min/1.73 m2 (sensitivity (S): 100 %, specificity (Sp): 49 %, negative-predictive value (NPV): 100 %) the probability of finding M-protein in urine is negligible. Patients with alpha heavy chain have a higher probability of having M-protein in urine. Thus, when the heavy chain of the M-protein is gamma or mu, serum cut-off value can be raised up to ≤4.9 g/L (S: 97 %, Sp: 52 %, NPV: 98 %).

Conclusions

Settling these two cut-off values when a new M-protein is discovered could avoid a significant number of urine analyses, optimizing laboratory and healthcare resources.

Authors: Teng Mark Feng , Ma Maggie
Published: September 2024

The present study examined self-efficacy, working memory, and English proficiency in a multimedia writing environment. The research design included a survey to assess self-efficacy and a writing assessment within a multimedia environment, while controlling for working memory capacity and levels of English proficiency. Data collection methods comprised a survey on self-efficacy beliefs in multimedia writing, a working memory task, and the standardized College English Test Band 4 in China. The participants were a total of 406 Chinese university students. The results support the reliability of the self-efficacy questionnaire, with five dimensions: linguistic knowledge, planning, monitoring, evaluation, and performance. These five factors were positively correlated with the students’ writing performance in a multimedia environment. The structural equation modeling findings suggest that working memory and English language proficiency moderate learners’ self-efficacy in EFL multimedia writing. Relevant implications based on the findings were discussed.

Published: September 2024

Currently, it is difficult to distinguish the inner quality of pachycarpous fruits using nondestructive instruments, and trace nutrients and flavor compounds are rarely considered in fruit sorting. In this study, the external features and internal quality indices of an extensively farmed citrus fruit, the Guanxi honey red pomelo, were measured. The correlation between the inner and external quality was analyzed using Pearson correlation, canonical correlation, and grey correlation analyses. This research innovatively introduced bitter substances and revealed that the height-diameter ratio could serve as a predictor for ultra-size fruits, which partially reflects inner quality indices. Several grey formulas were developed to express these correlations and were fitted to a matrix, which demonstrated accuracies at all level 1 (C < 0.35, P > 0.95). Based on the matrix, fruit quality analysis of white and red pomelo showed high prediction accuracy in TSS and bitter substance indices (R2 = 0.6 – 0.8) and indicated that mature and symmetrical pomelo (height-diameter ratio of 0.9 – 1.1) exhibit a similar quality pattern. This study achieved rapid quality assessment using easy measurable shape characteristics and explored the application of characteristic bitter substances in the quality evaluation model, providing theoretical references and potential application guidance for pachycarpous fruit sorting, as well as introducing a new idea to incorporating characteristic quality into modeling index.

Pea is the delicious vegetable consumed in India. Conventional irrigation is being practiced to cultivate pea crop, which consumes lot of water and uneven distribution of soil moisture. Drip irrigation plays a major role for uniform distribution of water. Further water saving and maximum water use efficiency can be achieved through innovative technologies like soil moisture sensor based irrigation scheduling for pea. Moisture presence in soil can be detected by soil moisture sensors or Tensiometers. When irrigation is scheduled based on soil moisture measurement using tensiometers or soil moisture sensors, it would increase fresh pod yield of pea and improve water productivity.A research was conducted on pulse crop of pea (Pisum Sativum L.) to decide irrigation quantity and frequency according to the presence of soil moisture with different irrigation and fertigation treatments. The research findings indicated irrigation at the soil moisture tension of “30 kPa with 1.2 times more fertilizer application would bring maximum yield and water productivity of pea.

A trial was conducted to study the effect of drinking water frequency on production performance of lactating Deoni cows with the objectives to assess the effect of different drinking water frequency on water intake, dry matter intake and nutrient digestibility. Nine lactating Deoni cows were selected on the basis of age, body weight, parity, stage of lactation and milk yield and divided into three groups comprising of 3 animals in each group. The experiment was conducted in three periods in Switch over design in order to expose each group to all the three treatments. The control treatment (T1) received ad libitum drinking water whereas, treatment T2 and T3 received drinking water twice and thrice daily, respectively. Significantly higher water intake was noticed in thrice daily watering than rest of the treatments, while intake of water was decreased in twice daily watering compared to other treatments. Dry matter intake was positively correlated with water intake. Significant increase in dry matter intake was observed in ad libitum and thrice daily watering whereas, dry matter intake was decreased when frequency of watering adjusted to twice daily. The apparent digestibilities of all the nutrients including DM, CP, CF, EE and NFE was significantly improved due to restriction of drinking water to twice daily (T2). However, ad libitum and thrice daily watering were at par for DM, CP, CF and NFE digestibility except EE digestibility differ significantly in all the treatments.

Published: September 2024

The Andaman and Nicobar Islands have been actively seeking sustainable alternatives to plastic and recent research by the ICAR-Central Island Agricultural Research Institute (CIARI) and the ICAR-National Bureau of Plant Genetic Resources (NBPGR) has identified Macaranga nicobarica, commonly known as the “Giant leaf” plant, as a promising substitute for plastic packaging. This study investigates the potential of M. nicobarica as an alternative source for plastic plates, focusing on its growth, development, and leaf characteristics. Germplasm of M. nicobarica was collected from three locations in the Nicobar Islands and conserved for further study. Morphological observations were made on leaf production patterns and various leaf characteristics, and statistical analyses were conducted to compare these traits among different accessions of M. nicobarica and other relevant species (M. tanarius and M. indica). Significant variations were observed in leaf characteristics among M. nicobarica accessions, with some displaying larger dimensions and higher leaf area compared to others. Furthermore, M. nicobarica exhibited distinct differences in leaf characteristics compared to other species of the Macaranga genus. A dendrogram analysis confirmed the clustering of all M. nicobarica accessions, distinct from other studied species. The findings suggest that M. nicobarica, particularly accession IC: 626370, holds significant potential as an alternative source for plastic plates, owing to the size and texture of its large leaves. This research contributes to the ongoing efforts to reduce plastic dependency in the Andaman and Nicobar Islands, highlighting the importance of indigenous resources like M. nicobarica in fostering sustainable solutions for environmental challenges.

Thermoelectric coolers utilizing peltier effect offer a promising solution for cooling applications. This study elaborates the design and optimization of a TEC-operated cool chamber and evaluation of developed thermoelectric cool chamber. A number of elements need to be carefully considered during the design process, including heat load assessment, TEC module selection and effective heat dissipation techniques. Appropriate TEC modules are chosen based on estimated cooling load, temperature difference achieved, power consumption, maximum cooling capacity of each TEC and heatsink. The solar photovoltaic operated thermoelectric cool chamber comprises essential components such as SPV Panel, solar charger controller, battery, PWM controller, TEC module with heat sink, and insulated box (TCC unit). The design considerations involve estimating total power consumption and determining the number and ratings of solar panels, batteries, and power conditioning devices to ensure reliable electricity supply. The system operates on SPV-generated power, utilizing MPPT charge controllers to maximize power output. Pulsed width modulation (PWM) systems efficiently regulate power distribution to thermoelectric modules, optimizing performance. The thermoelectric cool chamber was developed of 40 L water capacity. It was observed that, the chamber and water temperature in developed thermoelectric cool chamber was reduced from initial temperature by 11.85°C and 11.56°C, respectively after 24 hours. The chamber and water temperature after 24 hours were 13.31°C and 13.49°C, respectively. The performance evaluation showed that the chamber’s cooling efficiency was influenced by factors such as cooling load and water volume. This comprehensive approach enables the development of an effective and sustainable thermoelectric cooling system suitable for various applications.
