Authors: Bastidas Orlando , Santiago Etenaldo Felipe , Silva Luciana Ferreira da
Published: January 2025

Desde 2001, as Nações Unidas incluíram em sua agenda a avaliação do desenvolvimento sustentável por meio de indicadores que viabilizam parâmetros de comparação entre diversos países. A despeito da eficiência desses indicadores como ferramenta de avaliação, estes podem ser melhorados e/ou adaptados para contextos específicos. Nessa perspectiva, no presente estudo foi avaliada a sustentabilidade da agricultura familiar, bem como identificadas as bases e diretrizes de desenvolvimento sustentável no município de Dourados, Mato Grosso do Sul (MS), Brasil, a partir das percepções dos agricultores familiares da região. A pesquisa foi orientada em estudos de caso exploratórios em campo, em 20 unidades de produção orgânica agroecológica certificadas, e também se recorreu a bancos de dados oficiais. Nesse contexto, foram propostos os Índices de Desenvolvimento Rural Sustentável (IDRS). A metodologia utilizada para a elaboração do Índice foi a análise de Cluster e o Biograma de Sustentabilidade. Os resultados para o Índice de Desenvolvimento Sustentável Integrado (S³) foram de 0,6998, o que indicou um nível estável de Desenvolvimento Rural Sustentável (DRS), com alguns indicadores em estado crítico. Diante desses resultados, foi possível concluir que os produtores do município estão inseridos em uma estrutura institucional e cultural de sustentabilidade; por outro lado, ainda se necessita a soma de esforços que colaborem para a melhoria da qualidade de vida e aquisição de bens primários naqueles sistemas produtivos, o que pode ser obtido pela maior participação dos institutos de governança e apoio técnico.
Paisagem, topofilia/topofobia e empreendedorismo: uma proposta de modelo teórico
Authors: Siffert Paulo Vitor , Silva João Paulo Moreira , Guimarães Liliane de Oliveira , Salume Paula Karina
Published: January 2025

Resumo: O objetivo deste ensaio foi criar um aparato teórico-metodológico que permita analisar os simbolismos da paisagem e como estas afetam – de maneira topofilica ou topofóbica – as relações dos empreendedores com o lugar. A proposta é entender um pouco mais como o contexto socioespacial do empreendedorismo pode direcionar o perfil de culturas empreendedoras locais a partir dos simbolismos, com cargas culturais, impressos na paisagem, e pela forma como esses significados são apreendidos pela comunidade empreendedora. Para tanto, recorremos aos debates teóricos desenvolvidos na Antropologia e Sociologia sobre cultura e nas discussões sobre paisagem e relações subjetivas com o lugar, correntes na Geografia Cultural. A aproximação dos conceitos de topofilia e topofobia foi inspirada pelo uso recente (2020) do termo, em um contexto mais prático e menos teórico, como sendo um dos fatores-chave para o desenvolvimento de um ecossistema empreendedor. Trata-se, então, de averiguar o potencial de uso e a validade desse conceito para a compreensão do fenômeno do empreendedorismo, sendo útil a busca por delinear um arcabouço teórico-metodológico para compreender com maior profundidade tais implicações.
Pro-environmental behavior and its determinants: evidence for Mato Grosso do Sul
Authors: Constantino Michel , Tabak Benjamin Miranda , Garcia Ricardo Alexandre Martins
Published: January 2025

This article investigates the importance of individual characteristics, including a proxy for testosterone levels (using the biological marker 2D:4D ratio as proxy), to explain students’ pro-environmental behavior. We employ machine learning modeling from artificial neural networks. We elaborate an environmental score based on 13 questions related to the environmental impact generated by the individuals. We analyzed which profile variables are most important to explain pro-environmental behavior. The results are in line with the literature, which proves the importance of the 2D:4D ratio as a predictor of pro-environmental behavior (testosterone levels), gender, and age. These results suggest evidence for elaborating public policies to preserve and reduce environmental degradation based on individuals’ characteristics and biological markers.

Published: January 2025

The availability of quality seeds is critical to supporting the sustainability of agriculture, which is further reinforced by the success of contract farming between seed companies and partner farmers. To foster a mutually beneficial partnership, it is essential to align the needs of farmers with the facilities and services provided by the company through well-defined contract terms and conditions. This study aims to explore the contract attribute preferences and their importance levels among farmers, growth leaders, and companies using a quantitative approach. A discrete choice experiment utilizing the conditional logit model was employed to investigate the preferences of 170 farmers, while a descriptive analysis was used to outline the preferences of other stakeholders. The findings indicate that farmers prefer written agreements over informal ones, favor shorter contract durations, and demand higher prices. Additionally, farmers showed a marked preference for receiving inputs, incentives, and credits. The preference patterns of stakeholders align with those of farmers regarding agreement form, inputs, price, incentives, and credit, although stakeholders tend to favor contracts with longer durations. Based on the rank-based quotient method, both growth leaders and farmers identified price, input subsidies, incentives, credits, agreement form, and duration as the most important attributes in maize seed partnership contracts, in descending order of importance. Contrarily, the company prioritizes input subsidies over other attributes, including price, duration, credit, incentive, and agreement form. These insights can inform the design of more suitable and effective contracts, thereby fostering sustainable partnership relationships in the future.

Objectives. To determine the overall mortality and risk factors of COVID-19 patients who were admitted to the Home Isolation (HI) program in Bangkok, Thailand, during the epidemic crisis in 2021.

Methods. We conducted a retrospective cohort study using the data from a government telehealth application from July to December 2021. The vital status was verified from the government database on September 20, 2022. We used survival analysis to analyze the 28-day mortality and independently associated factors.

Results. Of 90 854 reported cases, the average age was 37.27 years, and half were men. Initial symptoms included being asymptomatic (51.66%), having mild symptoms (35.60%), or experiencing severe symptoms requiring nonurgent (11.27%) or urgent referral (1.47%). The 28-day mortality rate was 0.80%. Factors associated with 28-day mortality included older age, male gender, higher body mass index, severity of initial symptoms, and time to admission.

Conclusions. The Home Isolation program was able to manage a high volume of patients, including severe cases, exceeding its initial design. Thailand’s COVID-19 mortality rate remained relatively low compared with other countries. Proactive bed surge planning and continuous plan improvement were crucial for future preparedness.

Published: January 2025

Case:

A 14-year-old male athlete presented with a 9-month history of low back pain, worse with hyperextension. Nonoperative management for bilateral L4 spondylolysis had been unsuccessful. The patient underwent a novel magnetic resonance imaging (MRI) that generated a synthetic computed tomography (sCT). MRI/sCT revealed nonunion of the spondylolysis with persistent edema. The patient underwent minimally invasive bilateral L4 robot-navigated intralaminar screw fixation. CT at 3 months demonstrated complete healing.

Conclusion:

This case is the first to document the use of MRI-generated sCT in the management of pediatric spondylolysis, offering improved assessment of both bony and soft tissue pathology in a single study without the ionizing radiation of traditional CT.
Improved trafficability over soft soils using ground matting
Authors: Rushing John , Hansen Bradley , Parker Michael
Published: January 2025

Soft soils pose mobility challenges, even for vehicles designed with superior off-road capabilities. When numerous vehicles travel the same path, permanent deformation of the soil can result in rut depths that exceed vehicle ground clearance. These challenges can be overcome by modifying ground conditions to improve bearing capacity or spreading wheel loads over a greater area. Researchers at the U.S. Army Engineer Research and Development Center conducted field tests to quantify the performance benefits of a ground matting system made of connected fiberglass panels designed to improve vehicle mobility on soft soils. Soil conditions included silt, sand, and highly organic soil with varying strength. Test vehicles included wheeled trucks with gross weights of approximately 6350 kg per axle. Performance of the matting system was assessed by the number of allowable vehicle crossings with and without matting present. Results from testing showed that allowable number of vehicles increased by at least a factor of ten on the weakest soils. Data presented herein includes geotechnical site characterization, soil deformation as a function of traffic, and material characteristics for the fiberglass matting system.
Paleoenvironmental conditions and evolution of a muddy turbidite system: an integrated sedimentological and ichnological analysis
Authors: Cabrera-Ortiz José F. , Dorador Javier , Rodríguez-Tovar Francisco J. , Pérez-Asensio José N.
Published: January 2025

Recent advances in characterization of turbidite-fans have been achieved through various methodologies, including flume-tank experiments, numerical modeling, seismic analysis, and integrated core and outcrop studies. Ichnology has proven valuable for understanding turbidite systems by providing insights into paleoenvironmental conditions such as oxygen levels, nutrient availability, hydrodynamic energy, and sedimentation rates. Since the 1960s, the Nereites ichnofacies has been linked to flysch deposits, characterized by features such as graphoglyptids, shallow-tier ichnotaxa, complex grazing trails, and diverse, but low density, trace fossils. The aim of this study is to combine ichnological and sedimentological data to improve recognition of subenvironments in turbidite systems. Analysis of five sections in a late Miocene, muddy turbidite system in the Tabernas Basin (SE Spain) shows that: 1) the distal fan lobes are characterized by a high diversity and abundance of predepositional trace fossils linked to the Paleodictyon ichnosubfacies, indicating stable and oligotrophic conditions, and 2) the proximal fan lobes by a low diversity and abundance of postdepositional trace fossils with abundant Ophiomorpha rudis ichnosubfacies in areas close to the feeder channel.

Authors: Perez-Manchon David , Azpeleta-Noriega Clara , Gal-Iglesias Beatriz , Ruiz-Zaldibar Cayetana
Published: January 2025

Background
Sleep quality is a strategic public health priority and is the key factor in studying circadian rhythms and their chronotypes. University students are a particularly vulnerable population group. The objective of the research is to show the impact of an intervention aimed at improving sleep quality among first-year academic nursing students.
Methods
The study is a two-arm pilot randomized clinical trial conducted from October 2022 to March 2023. Two groups were randomly assigned to an experimental group (n = 20) that received a cognitive behavioural intervention of active-constructive learning methodology to improve sleep quality and a control group (n = 20) that followed their usual daily routine. In both groups, ambulatory circadian monitoring was carried out over a period of 7 days, and Pittsburgh Sleep Quality index questionnaire was administered, pre- and post-intervention. Satisfaction was assessed in the intervention group at the end of the intervention. This study is performed according to the CONSORT statement.
Results
Of the 40-participant included in the study, 85% were female and 15% male with a mean age of 19.8. After the intervention, circadian parameters of interdaily stability, rhythm regularity and amplitude, and sleep parameters such as less exposure to blue light 2h before bedtime and lower sleep latency improved in the intervention group.
Conclusions
Cognitive behavioural therapy intervention aimed at nursing students has improved the main marker of circadian health robustness and sleep quality, while provoking high degrees of satisfaction in the participants.

Authors: Torki Alireza
Published: January 2025

Aims: This study aimed to investigate the correlation between pregnancy complications and placental histopathology in samples collected at Shahid Sadoughi Hospital in Yazd from 2013 to 2022.
Method: A census sampling approach was utilized to examine all placental samples submitted to the pathology department at Shahid Sadoughi Hospital between 2012 and 2014. Following approval from the Research Council of the Faculty of Medicine at Shahid Sadoughi University of Medical Sciences in Yazd and clearance from the ethics committee, the study commenced. Stakeholders were briefed on the study objectives, methodology, and 15 data confidentiality. Patient records were scrutinized based on predefined criteria, and relevant information was extracted.
Results: The retrospective analysis included 210 subjects with an average age of 28.78±5.51 years. The average gestational age in the sampled cases was 32.98±4.09 weeks. The highest incidence of pregnancy-related pathologies was attributed to IUGR at 20.0% and IUFD at 18.1%. The predominant placental histopathological findings were categorized as no significant abnormalities (26.2%) and multifocal ischemic changes (21.0%).
Conclusion: The study findings establish a significant association between pregnancy complications like IUGR and IUFD and specific placental histopathological patterns. Notably, a substantial proportion of cases exhibited diverse placental histopathologies, particularly those with unremarkable findings and multiple ischemic changes. These results underscore the importance of diligent placental histopathological assessments in the investigation of pregnancy complications, aiding in enhanced clinical decision-making. The study recommends comprehensive placental histopathological evaluations in suspected high-risk pregnancies to improve clinical management strategies

Kappaphycus alvarezii (Doty) Doty ex Silva, a red seaweed widely cultivated for carrageenan polysaccharide, is also a potential source of the valuable pigment phycoerythrin (PE). Therefore, this study aims to extract phycoerythrin from K. alvarezii, evaluate its antimicrobial, antioxidant, and anticancer activities, and identify its biomedical potential for future therapeutic applications. The protein content of phycoerythrin pigment extracted from K. alvarezii was found to be 69.84% and showed excellent antimicrobial activity against Klebsiella oxytoca and Proteus mirabilis, with a minimum inhibition zone of 11 mm. It showed significant in vitro antioxidant activity, as analyzed using total antioxidant, hydrogen peroxide scavenging, reducing power, DPPH, and ABTS assays. Further, the pigment exhibited potent cytotoxicity against a human lung cancer cell line, with an IC50 value of 131.7 µg mL-1. Furthermore, increasing the concentration of phycoerythrin pigment decreased the cell proliferation and induced apoptosis, as confirmed by Annexin V/PI staining. Comprehensive characterization using FT-IR, HPLC, and GC-MS analysis revealed the nature of pigment and functional groups, highlighting its potential for biomedical applications. The molecular docking of K. alvarezii-derived compounds revealed significant binding affinities with 13 antibacterial target proteins. These results highlight the potential of K. alvarezii bioactive compounds as promising antibacterial agents. The phycoerythrin extract from K. alvarezii demonstrated potent antimicrobial, antioxidant, and anticancer properties, with significant cytotoxicity against lung cancer cells and confirmed apoptosis induction.

Design and performance analysis of n-MoS 2 /p-Si heterojunction solar cell for emerging optoelectronic applications
Authors: Pradhan Ritishri Priyaranjan , Mishra Sheo Kumar , Singha Monoj Kumar , Kumar Arvind
Published: January 2025

Sustainable, green, clean energy sources based electrical energy conversion is essential to the modern world. A solar cell or photovoltaic cell acts as a major part of that to accomplish the energy interest. Two-dimensional materials such as Molybdenum disulphide (MoS2) based heterojunction solar cells attracted researchers for their extraordinary chemical, physical, thermal, mechanical, optical, and electrical stability. In this work, we simulated the electrical behavior of n-MoS2/p-Si-based heterojunction-based solar cells with the help of the Solar Cell Capacitance Simulator - One Dimensional (SCAPS-1D) simulation tool. We examine the performance of MoS2-based solar cells by varying the active layer’s thickness, which leads to the changing of the band gap variation in the electron affinity, and explore the performance of devices with different metal contacts. The impact of interfacial defect density, series, and shunt resistance is also evaluated on various working temperatures of the devices. The best combinations of different parameters give an efficiency (η) of 12%, which is sufficiently high enough compared to the previously published experimental work. This will provide essential insight into the development of high-performance solar cells with two dimensional (2D) materials.
Bile Leaks Requiring Multiple ERCPs – Risk Factors for Poor Outcomes
Authors: Miller Alexander T. , Dairi Obaida F. , Sogaard Kristian K. , Gardner Timothy B.
Published: January 2025

Introduction: Bile leaks may require intervention with endoscopic retrograde cholangiopancreatography (ERCP). Success rates with ERCP are reported to be over 90%; however, a subset of patients still require multiple ERCPs to achieve resolution. We investigated demographic and interventional factors necessitating multiple ERCPs to achieve bile leak resolution.Methods: We retrospectively reviewed cases from 2014–2024 at our institution that involved bile leaks requiring an ERCP. We categorized leaks into those that required two or less ERCPs for resolution versus those that required three or more ERCPs while examining the demographic and interventional risk factors between the two groups.Results: A total of 143 cases were included in our analyzed sample. 83.2% (n = 119) required two or less ERCPs for resolution while 16.8% (n = 24) required three or more ERCPs until resolution. We did not find a difference between the etiology of the leak or the location when the leak was identifiable; however, we did observe a significantly higher percentage of cases where the leak was not identified in the three or more group compared to the two or less group, 33.33% vs. 14.29% (p = 0.0373). Cases requiring two or less ERCPs more likely used plastic stents, 89.1% vs 66.7% (p = 0.010). Finally, cases requiring three or more ERCPs were more likely managed with a sphincterotomy without stent placement, 12.5% vs 1.7% (p = 0.033).Conclusions: Performing stent placement AND biliary sphincterotomy at time of index ERCP led to more rapid resolution of bile leaks, irrespective of patient characteristics or type of leak.
CPMFD: An algorithm for Classification of Point Mutations together with Frameshift Determination in related mRNA sequences
Authors: Mondal Probir , Banerjee Pratyay , Basuli Krishnendu
Published: January 2025

Mutations are responsible for the genetic origin of various diseases. Existing techniques for mutation identification often fails to detect the full spectrum of mutations in complex genomes hindering progress in diagnosis, treatment and prevention of diseases. Here we propose an algorithm to identify the location
and type of mutation occurring in a mutated string with respect to a reference mRNA sequence. In addition to identifying insertion and deletion, by constructing suitable rational combinations of the prime numbers, our algorithm is able to classify point mutations in a novel way by distinguishing missense mutation from silent mutation. Moreover, the method allows to locate regions in the sequence undergoing frameshift. This algorithm turns out to be efficient when applied on simulated dataset. Application of this framework to two haplotypes of the Plasmodium falciparum datasets exhibit different mutation profile to develop similar chloroquine resistance. We investigate the β-globin genes found in pygmy and common chimpanzee to identify mutations of all sort distinguishing the two species. Additionally, in Alzheimer datasets, our method meticulously identifies true variations in the related genes.

Bayesian estimation of failed transfer of passive immunity IgG cut-off values for predicting pre-weaning morbidity in beef calves
Authors: Thompson Alexis C. , Scott Matthew A. , Dewell Renée D. , Dominguez Brandon J.
Published: January 2025

Failed transfer of passive immunity (FTPI) has been used to predict pre-weaning disease in beef calves. However, FTPI has a wide range of reported sensitivities and specificities; therefore, the diagnostic value of testing for FTPI to predict a beef calf’s disease risk is questionable. Our objective was to determine the positive and negative predictive value of FTPI classification on pre-weaning morbidity in beef calves using a Bayesian latent class analysis. Pre-weaning health records and IgG concentrations from 1,569 beef calves across 3 populations were used. Calves were classified as having FTPI using 7 IgG cut-off values (500, 800, 1,000, 1,200, 1,600, 1,800 and 2,400 mg/ dL). A Bayesian latent class model assuming conditional in­dependence between the IgG concentrations and morbidity diagnosis was used to obtain estimates of the test sensitivity, specificity and positive and negative predictive value for the IgG cut-off values using informed priors; estimated herd cumu­lative incidence of morbidity ranged from 3.5% to 26.1%. Immu­noglobulin G had a median (95% credible interval) sensitivity ranging from 28% (22%, 36%) for 500 mg/dL to 47% (40%, 55%) for 2,400 mg/dL and a median (95% credible interval) specificity ranging from 98% (95%, 100%) for 500 mg/dL to 64% (62%, 67%) for 2,400 mg/dL. Testing for FTPI performed the best in herds with a high cumulative incidence of morbidity (> 15%). In herds with low cumulative incidence of morbidity, testing for FTPI did not aid in the detection of calves that would develop pre-weaning morbidity.
Accessing Education: Equity, Diversity, and Inclusion in Online Learning
Authors: Ikebuchi Shelly
Published: January 2025

As Canadian post-secondary institutions emerge from the pandemic restrictions, they are in a historically unique position to assess how online education has both facilitated and hindered learning, and how the effects might be greater for some. In this study, open-ended comments from the Canadian Digital Learning Research Association 2022 Spring National Survey were analyzed to understand how online and/or hybrid learning both supported equity, diversity, and inclusion (EDI) and presented EDI-related challenges. The findings were that: (a) online and hybrid learning presents challenges of access for students marginalized by “race,” class, and location; (b) online and hybrid learning supports EDI by increasing access and flexibility; (c) pedagogy and course design are central to ensuring that online and/or hybrid learning supports EDI; and (d) student experiences and expectations around online learning indicate a need for support and flexibility. These findings highlight some of the promises of online and hybrid learning, but they also bring to light some of the challenges. This paper discusses three challenges, access, pedagogy, and technology, as well as flexibility, and recommendations that might begin to address EDI.

Published: January 2025

This study investigates students' understanding of scientific article writing techniques, their perceptions of the challenges they face when writing these articles, and the features of guidebooks that best meet their needs. Employing a mixed-methods approach with a Convergent Parallel design, the research combines quantitative data collected through tests and questionnaires with qualitative insights from open-ended questions. The findings reveal that students' knowledge of scientific article writing falls into the moderate range (46%). While they demonstrate a good understanding of submitting articles to journals, they struggle with using AI applications, properly citing references, and documenting post-publication work. Students' primary challenges include articulating their research methodology, crafting effective sentences and paragraphs, structuring the article appropriately, utilizing AI technology during the writing process, and navigating the submission process to scientific journals. Furthermore, the study highlights students' desires for a guidebook that goes beyond theoretical discussions. They are looking for one that includes practical examples, video tutorials, project assignments, and guidance on using AI platforms to aid their writing. These insights significantly contribute to designing a scientific article writing guidebook tailored to the needs of Generation Z students, ultimately enhancing the quality of scientific writing education.

Published: January 2025

O presente artigo tem por objetivo explorar, através da relação entre Sócrates e a formação – e tendo como base o desenvolvimento de sua mestria –, como Sócrates constitui, a partir da filosofia, uma forma de vida e, como isso, passa a influenciar o desenvolvimento de seu papel como mestre. O material utilizado, visando bem contemplar ao objetivo proposto, se dá pelo contato com os diálogos platônicos, tendo como referência, sobretudo, a obra Apologia de Sócrates. A pesquisa também possui por fundamento a utilização de materiais complementares de pensadores e comentadores que agregam e auxiliam para um maior aprofundamento da temática. Assim, o trajeto desenvolvido pelo presente escrito repousa, inicialmente, na identificação de como Sócrates estabelece, através da filosofia, uma forma de vida. Na sequência, o texto nutre-se em torno da análise das dimensões do ocupar-se, tomando como referência nessa explanação a fundamentação estabelecida a partir do contato com o sentido pedagógico das metáforas socráticas. E, como último movimento da pesquisa, se postula uma análise reflexiva a respeito da contribuição de Sócrates para a formação humana, tendo como base os dois passos discutidos: uma forma de viver ancorada no viés filosófico e uma pedagogia exemplificada pelas metáforas socráticas.
Adenocarcinoma of small bowel: why is it so rare

Small bowel adenocarcinoma (SBA) is a rare gastrointestinal neoplasm and despite the small intestine's significant surface area, SBA accounts for less than 3% of such tumors. Early detection is challenging and the reason arises from its asymptomatic nature, often leading to late-stage discovery and poor prognosis. Treatment involves chemotherapy with a 5-fluorouracil combination, but the lack of effective chemotherapy contributes to a generally poor prognosis. SBAs are linked to genetic disorders and risk factors, including chronic inflammatory conditions. The unique characteristics of the small bowel, such as rapid cell renewal and an active immune system, contributes to the rarity of these tumors as well as the high intratumoral infiltration of immune cells is associated with a favorable prognosis. Microsatellite instability in SBA is associated with a high tumor mutational burden, affecting the prognosis and response to immunotherapy. The presence of PD-L1 and programmed cell death, along with tumor-infiltrating lymphocytes, plays a crucial role in the complex microenvironment of SBA and contributes to a more favorable prognosis, especially in the context of high MSI tumors. Stromal tumor infiltratinglymphocytes are identified as independent prognostic indicators andthe association between MSI status and a favorable prognosis, emphasizes theimportance of evaluating the immune status of tumors for treatment decisions. 
In conclusion, small bowel adenocacinoma is a rare disease, the organ has some caracteristics that contributes to the small incidence of SBA. Finally, the diagnosis, treatmentand survival are challenging.
Produção artesanal de queijos: avaliação das condições de processamento, da qualidade higiênico sanitária e físico-química de queijos tipo coalho e manteiga

Published: January 2025

Os queijos mais populares na região Seridó são os queijos de coalho e manteiga, cujo processo de fabricação favorece a contaminação microbiológica desses produtos e a variação na composição dos mesmos. Diante da importância econômica,
objetiva-se avaliar as condições de produção, bem como a qualidade microbiológica e físico-química dos queijos de coalho e de manteiga produzidos na região Seridó/RN. Para tanto, foi aplicado um check list em cinco queijarias artesanais, visando avaliar as condições higiênico-sanitárias de produção dos queijos, como também foi realizado um treinamento, a implantação de Boas Práticas de Fabricação e acompanhamento das medidas corretivas. Além disso, foram realizadas análises microbiológicas de coliformes a 35º e 45° em amostras de leite, queijos, água e utensílios, contagem de bactérias mesófilas no leite, Staphylococcus spp. nos queijos e utensílios e Salmonella sp. nos
queijos, totalizando 30 amostras de cada item analisado de cada queijaria artesanal. Foram também realizadas análises físico-químicas (umidade, cinzas, lipídios, pH, acidez, teor de
cloretos e cor) em cinco amostras de queijo de coalho e em cinco de queijo de manteiga. Os resultados encontrados mostraram um elevado percentual de não conformidades em
todos os estabelecimentos analisados. Durante o diagnóstico a contagem de bactérias mesófilas no leite foi superior ao recomendado à legislação, assim como a contagem de
coliformes a 35°C e 45°C nas amostras de água. Quanto aos queijos de coalho e manteiga em ambos foi detectada a presença de Salmonella sp. no momento do diagnóstico.
Contagens elevadas também foram observadas para as amostras de utensílios. Após a implantação das BPF nas queijarias artesanais observou-se aumento das porcentagens de
conformidades nos itens higiene do ambiente e manipulação de alimentos, o que refletiu na melhoria das condições de processamento do queijo de manteiga através da redução
significativa (p<0,05) de coliformes a 35°C e 45°C. Neste queijo assim como no queijo de coalho, foi observada ausência de Salmonella sp. nas amostras após a implantação das
BPF. Em relação aos aspectos físico-químicos, os queijos apresentaram variação na composição química entre os diferentes produtores da mesma região, no entanto se
encontraram dentro dos parâmetros estabelecimentos pela legislação. Diante desses resultados enfatiza-se a importância da implantação das Boas Práticas de Fabricação para
a melhoria da qualidade microbiológica de queijos artesanais. E em relação aos parâmetros físico-químicos demonstrou-se que a forma de fabricação artesanal apesar de proporcionar a elaboração de queijos com constituintes diferentes, garante a
conformidade desses produtos com a legislação.
Variação da biomassa em guildas tróficas de peixes em resposta a seca em um reservatório no semiárido

Published: January 2025

Os estudos sobre a composição das guildas tróficas de peixes é fundamental para a determinação da estrutura trófica e da utilização dos recursos alimentares por diferentes espécies em ambientes decorrentes de variações temporais, por exemplo, uma seca prolongada, tendo efeito sobre a riqueza e abundância dessas espécies, modificando a biodiversidade. Assim o presente trabalho tem como objetivo mostrar que com a redução no volume de água e pluviosidade do reservatório de Santa Cruz promove alterações negativas na biomassa das espécies de peixes presentes nas guildas tróficas. Foram utilizados dados precipitação (mm), percentual do volume de água acumulado e biomassa capturada dos peixes trimestralmente, entre fevereiro de 2010 e novembro de 2014. Para a análise foram utilizados dados de CPUE, com o objetivo de verificar alterações significativas para cada guilda trófica foi aplicada PERMANOVA, posteriormente foi aplicado o teste não paramétrico de Kruskal-Wallis para verificar qual espécie apresenta maior contribuição de CPUE entre os anos de coleta. Para verificar variação na formação das guildas foi feito uma analise de presença e ausência para todas as espécies e por fim com o objetivo de verificar a organização temporal das guildas tróficas foi aplicado o teste de correlação não paramétrico de Sperman. Foram encontradas 22 espécies apresentando variação temporal distribuídas em cinco guildas tróficas. A guilda Detritívora/Iliófaga apresentou maior biomassa seguido das guildas Carcinófaga, Insetívora, Onívora e Piscívora. Nossos resultados mostram que a redução temporal na biomassa das guildas tróficas Detritívora/Iliófaga e Carcinófaga estão relacionadas com os fatores de redução de volume de água e precipitação, já as demais guildas suas oscilações temporais de biomassa podem esta relacionadas com diversos fatores como exploração de recurso alimentar em maior abundância em determinado ano, favorecendo a presença de algumas guildas.
Toxicidade de inseticidas neonicotinoides sobre abelhas Apis mellifera L. (africanizadas)
Authors:   , Soares Jefferson Bruno Carvalho
Published: January 2025

As abelhas melíferas apresentam um importante papel tanto na parte econômica como ambiental. Entretanto, nos últimos anos tem sido observado um declínio em nível mundial das colônias de abelhas, causando preocupação entre pesquisadores e apicultores. A exposição aos agrotóxicos pode acarretar sérios problemas para as abelhas e aos serviços de polinização. Nesse sentido, é de extrema importância determinar a toxicidade de inseticidas que são utilizados para o controle de pragas. O objetivo desse trabalho foi determinar a toxicidade dos produtos (Actara® 250 WG – Tiametoxam); (Evidence® 700WG – Imidacloprido1); (Nuprid® 700WG Imidacloprido2); (Orfeu® 200WG – Acetamiprido) e (Focus® 500WG – Clotianidina) sobre abelhas Apis mellifera, tendo sido avaliados alguns parâmetros toxicológicos, como Tempo Letal (TL50) para a aplicação tópica e oral, Dose letal (DL50) para aplicação tópica e Concentração letal (CL50) por ingestão, além de determinar o coeficiente de periculosidade (HQ). Para isso abelhas foram expostas aos inseticidas em diferentes concentrações e os dados de mortalidade submetidos às análises de sobrevivência e regressão Logit. Independente da forma de exposição todos os inseticidas testados ocasionaram a morte de 100% das abelhas, com a TL50, variando entre 0.68 a 3.85h para exposição tópica e 0.64 a 4.2h para exposição oral. Para a DL50 e CL50, o tiametoxam, Imidacloprido1, imidacloprido2, acetamiprido, e o clotianidina apresentaram os respectivos valores para as DL50, 7.5, 38, 57, 131, 10.5 ng/abelhas e CL50, de 5.56, 24.4, 278, 50.8, 6,8 ng.μl-1 respectivamente. Quanto ao Coeficiente de Risco (HQ) todos os inseticidas independente da cultura ou praga apresentaram um HQ maior que 50, variando de 157,7 (acetamiprido utilizado no algodão para o controle do Aphis gossypii) a 66.666,7 (tiametoxam utilizado no café para o controle da Leucoptera coffeella e Dysmicoccus texensis), mostrando o altíssimo nível de periculosidade destes inseticidas para as abelhas.
