Abstract Honeybees (Apis mellifera L.) (Hymenoptera: Apidae) coexists with humans in urban habitats foraging, mainly, sources containing carbohydrates. The behavior and risks for bees using soft drinks in their diet are poorly studied. The time spent by bee workers visiting soft drink leftovers in plastic cups and its death were evaluated. Bee workers spent more time visiting soft drinks in plastic cups (200 mL) than flowers of Schinus sp. (Anacardiaceae), Anadenanthera sp. (Fabaceae), Vernonia sp. (Asteraceae), Citrus sinensis L. (Rutaceae) and Cissus rhombifolia Vahl (Vitaceae), the five most visited honey plants in the field. Drowning mortality and the bee preference varied with the amount of soft drinks leftovers in cups. We present the first study of behavior and drowning mortality of A. mellifera feeding on leftover soft drink in plastic cups in urban areas, in the Brazilian Cerrado biome. This study may help to understanding the adaptive mechanisms of honeybees to explore habitats dominated by humans and unusual diets.

Abstract The application of biostimulants in agriculture has been used to increase crop yield. This study evaluated the effects of exogenous application of thiamine and nicotinamide on soybean plants. The experiment was conducted in Cassilândia, MS. The randomized blocks design with 5 treatments and 8 replications was used. The treatments consisted of concentrations of nicotinamide and thiamine at 0, 50, and 100 mg L-1 of water, applied exogenously when the plants were at the V3 stage. Gas exchange, number of grains per pod, number of pods, and grain yield were assessed. Plant height was increased by applying vitamins, with all treatments outperforming the control. The application of nicotinamide or thiamine at doses between 50 and 100 mg L-1 favors the development and grain yield of soybean plants, making it possible to use them as a biostimulant.

Published: February 2025

RESUMO O presente trabalho visou estabelecer uma relação entre os níveis de desfolha, em diferentes épocas de desenvolvimento da cultura de tomate, e sua influência na produção.Os tratamentos consistiram em cinco níveis de desfolha (0, 25, 50, 75 e 100%) em cinco diferentes estágios fenológicos da cultura (15, 30, 45, 60 e 75 dias após a germinação). Os dados obtidos revelaram que uma desfolha de 25%, efetuada em qualquer época do ciclo cultural, não interferiu na produção enquanto que uma desfolha de 100%, nas diferentes fases da cultura, reduziu significativamente a produção. Além disso, observou-se que os índices de 50% e 75% de desfolha prejudicaram a produção quando efetuados aos 30 dias, embora não tenham interferido quando realizados aos 15 e 45 dias, podendo até ser favoráveis como foi constatado na desfolha de 75% aos 60 dias.

RESUMO Neste trabalho teve-se em vista testar um novo tipo de lona plástica de polietileno com aditivos para a sua maior impermeabilidade, procurando apresentar uma nova alternativa no expurgo de cereais ensacados. Os testes abrangeram estudos comparativos entre esse novo tipo de cobertura com outras duas tradicionais lonas de PVC, de uso comum no tratamento de cereais. Esses estudos comparativos foram realizados em instalações da CEAGESP, em São Paulo, entre os meses de abril a junho de 1986, tendo como base o controle de infestações de Sitophilus zeamais Motschulsky, principal praga do milho armazenado. Os tratamentos com 3 tipos de lonas plásticas incluíram 2 dosagens de fosfina (2 e 4g por tonelada de cereal) e 2 períodos de exposição (72 e 96 horas). Os resultados apresentaram um completo controle dos estágios adultos da praga. O controle dos estágios imaturos de S. zeamais variou de 99,12 a 99,86% entre os tratamentos, não mostrando diferenças sensíveis no desempenho dos diferentes tipos de lona. De acordo com as condições experimentais, concluiu-se que a nova lona plástica de polietileno pode ser comparada em nível de eficiência com tradicionais lonas de PVC comumente empregadas no expurgo de cereais armazenados.

RESUMO Oobjetivo deste trabalho foi avaliar a estabilidade e a persistência de dois tipos de formulações deBaculovirus anticarsia desenvolvidas pelo Instituto Biológico do Estado de São Paulo e que foram armazenadas em condições ambientais e submetidas à radiação ultravioleta em testes de laboratório e campo. A formulação pó molhável (PM) foi preparada mediante a impregnação direta das suspensões de vírus e adjuvantes sobre uma mistura de inertes de origem mineral, em que predominava o caulim. A formulação óleo emulsionável (OE) foi obtida a partir da incorporação do patógeno suspenso em água com óleo de milho e adjuvantes. No teste de estabilidade, as formulações, o tratamento padrão (vírus semi-purificado) e a testemunha (água) foram mantidos em condições ambientais (prateleira), abrigados da luz, e a cada 120 dias amostras eram inoculadas em dieta artificial e fornecidas às lagartas deAnticarsia gemmatalis no início do 4º ínstar. As observações foram feitas durante 20 meses. Para o estudo do efeito protetor das formulações foram realizados dois testes sendo um representado pela radiação proveniente de lâmpada germicida (espectro ultravioleta) e outro em condições naturais (radiação solar). No caso da persistência (radiação solar), as formulações, o produto padrão (vírus impuro resultante da maceração de lagartas infectadas) e a testemunha (água) foram pulverizados, no campo, em parcelas de soja do cultivar IAC-8. Amostras de folíolos coletados no terço superior das plantas no dia da aplicação e após 1, 3, 7 e 14 dias foram levadas ao laboratório e fornecidas a lagartas de A. gemmatalis para avaliar a perda de atividade do patógeno em função do tratamento. Após 20 meses de armazenamento, a formulação OE perdeu apenas 18,33% de sua atividade original, enquanto a formulação PM já aos 12 meses teve sua eficiência reduzida para apenas 11,67%. Não foram constatadas diferenças entre as formulações com relação ao efeito protetor contra a radiação ultravioleta emanada de lâmpada germicida, pois ambas conferiram proteção ao vírus, se comparado com o patógeno semi-purificado. Em condições de campo, a formulação OE favoreceu a persistência do patógeno, mantendo mais de 60% da atividade após quatorze dias da aplicação. A formulação PM foi consideravelmente removida das folhas pela chuva.

RESUMO O presente estudo avalia comparativamente a estrutura da pele normal de bubalinos e bovinos, através de biópsias incluídas em parafina e coradas pelos métodos de Hematoxilina-Eosina (H.E.) para evidenciação dos co ponentes celulares, de Mallory para evidenciação de fibras colágenas e elásticas e de Perdrau para fibras reticulares. Demonstrou-se que há grande semelhança na estrutura da pele das duas espécies, variando basicamente no número de folículos pilosos, que é maior em bovinos e no aspecto das glândulas sebáceas, que é multilobular nos búfalos e bilobular nos bovinos. Revelou-se ainda que as fibras reticulares estão distribuídas de forma semelhante nas duas espécies e que na região da prega ano-caudal, os bubalinos apresentam diferença no número de feixes de fibras elásticas na derme, determinando um tecido conjuntivo mais frouxo que em bovinos.

ABSTRACT The present work evaluated the tuberculin skin test for the diagnosis of tuberculosis in buffaloes. In Experiment I a comparative study was carried out of tuberculin skin reaction between buffaloes and bovines experimentally sensitized with M.bovis or M.avium that showed reactions 1.8 times greater in caudal fold than in the cervical region of buffaloes and cervical reactions 1.69 times greater in buffaloes than in bovines. The caudal fold test (CFT) reading by paquimeter was suggested, classifying as positive the reactions greater than 10.O mm, suspect between 6.4 and 9.9 mm and negative when smaller than 6.3 mm. In the cervical comparative test (CCT), buffaloes were classified as reagent when skin reaction was greater than 5.0 mm, suspect between 3.0 and 4.9 mm and negative when smaller than 2.9 mm. In Experiment II, the tuberculin tests in buffaloes naturally exposed to M.bovis or other environmental mycobacterias were compared to the anatomic, histopathological, bacteriological and molecular biological analysis which revealed that the CFT showed 43.24% of false positive results and 33.33% of false negative results. If the modified values were used, percentage of false positive results decrease to 10.81% and zero respectively in both tests, although the percentage of false negatives do not change. There was no significant interference of environmental mycobacterias infection in the buffalo tuberculin tests.

RESUMO Myocastor coypus é um roedor silvestre originário da América do Sul que habita o sul do Brasil, estendendo-se para a Argentina e Uruguai, onde é conhecido como "nutria". Realizou-se um levantamento da fauna parasitária deste roedor no seu habitat natural, identificando os nematódeos do intestino delgado, bem como taxas de prevalência, abundância, intensidade média e amplitude de variação dos encontrados. Foram capturados e sacrificados 24 ratões-do-banhado, durante o período de Abr/97 a Nov/97. Em seguida, foram necropsiados, tendo-se acesso ao intestino delgado. O conteúdo deste órgão foi colocado em um balde graduado, onde 50% deste foi processado em tamis de malha O,150 mm e inspecionado macroscopicamente na busca de nematódeos. Os parasitas encontrados foram acondicionados em frascos contendo A. F. A., para posterior processamento e identificação. Os resultados obtidos para prevalência, abundância e intensidade média, respectivamente, foram os seguintes: Strongyloides spp. ( 83,33%; 247,92 e 297,50), machos de Longistriata maldonadoi (62,50%; 9,25 e 14,80), machos de L. myopotami (91,67%; 141,42 e 154,27), fêmeas de L. maldonadoi e L. myopotami (87,50%; 144,92 e 165,62) e Trichostrongylus colubriformis (54,17%; 21,46 e 39,62).

Resumo O objetivo é refletir sobre o Código de Águas de 1934 e os serviços de abastecimento de água e coleta de esgotos no Brasil no primeiro governo de Getúlio Vargas. Tratado pela historiografia majoritariamente como um instrumento para regular o setor de energia hidrelétrica, o código apresenta elementos que o extrapolam: regular o uso da “água” imposto pela conjuntura de acumulação ampliada do capital e sistematizar uma legislação difusa e seus diferentes usos, colocando em evidência questões como salubridade, poluição etc. Tais elementos, por sua vez, correspondem aos planos de Vargas de “reconstruir” a nação. Para tanto, foi realizado um balanço historiográfico sobre os temas e analisada a legislação pertinente.

The SOFA scale should be used to predict the outcomes of thermal injury. Objective. To study the possibilities of the SOFA scale in predicting the outcomes of thermal injury in stratification groups of revised Frank index (RFI). Material and methods. A retrospective study included 196 patients stratified into 3 groups: RFI≤70 (54 patients, all survived), RFI 71—180 (120 patients: 96 survived, 24 died), RFI≥181 (22 patients, all died). We analyzed SOFA scores within 3 days after injury (SOFA1, SOFA2, SOFA3) and compared in patients of three groups stratified by RFI including between patients with RFI≤70 and survivors with RFI 71—180, survivors and deceased patients with RFI 71—180, with RFI ≥181 and deceased patients with RFI 71—180. Results. SOFA score within 3 days after injury was significantly higher in deceased patients compared to survivors. After 3 days, SOFA scores were similar (in patients with RFI≤70 and survivors with RFI 71—180, as well as in patients with RFI≥181 and deceased patients with RFI 71—180). Scores were significantly higher in deceased patients with RFI 71—180 compared to survivors for 3 days. ROC analysis of injury outcome depending on SOFA1, SOFA2 and SOFA3 scores showed that all areas under ROC curves (AUCs) exceeded 0.9 with maximum AUC for SOFA3 (0.960). The cutoff point for SOFA1-SOFA3 was SOFA score ≥4. SOFA score ≥4 predicted unfavorable outcomes, SOFA score<4 predicted favorable outcomes. Conclusion. SOFA score characterized clinical severity in RFI-stratified groups. SOFA score ≥4 predicted unfavorable outcomes. Prediction of outcomes after thermal injury using SOFA scale is the most relevant for patients with RFI 71—180.

Objective. To develop the optimal method for assessing the risks of difficult tracheal intubation in obese patients. Material and methods. A prospective study included 116 patients who underwent surgery in 2022. To predict the risk of difficult tracheal intubation, the authors used the original scale of high-risk tracheal intubation (SHORT). Neck circumference was measured in all patients using a standard centimeter tape. The authors measured mouth opening width, maximum range of movements in atlanto-occipital joint using a universal medical goniometer. In addition, all patients were divided by gender. Depending on statistical significance of all parameters, all indicators were assigned points from 0.5 to 1.5. ROC-analysis was performed. Results. AUC was 0.906±0.045 with 95% CI 0.817—0.994. This model was significant (p<0.001). Difficult tracheal intubation was predicted by SHORT score ≥2. Sensitivity and specificity of the model were 90.5% and 80.0%, respectively. Conclusion. SHORT has demonstrated diagnostic value in predicting difficult airways in bariatric surgery. According to the authors, this scale can improve the quality of predicting difficult tracheal intubation in obese patients, and, accordingly, improve the quality and safety of anesthetic management.

Postoperative cardiovascular complications (CVC) are associated with higher morbidity and mortality. Ambiguity in definition of CVC creates confusion in assessment and management of patients. Objective. To determine the incidence and timing of CVC after major abdominal surgery, as well as their impact on 30-day mortality. Material and methods. A prospective cohort study was conducted between January and May 2022. Data were collected in patients who underwent major abdominal surgery. The primary outcome measure was CVC defined by the consensus “Standardized Endpoints for Perioperative Healthcare Outcomes—Key Outcomes for Perioperative and Anesthesia Care” within 30 days after surgery. The secondary outcome measure was 30-day postoperative mortality. Results. The study included 403 patients, and 21 (5.2%) ones developed CVCs. Thirty-three (8.2%) patients died within 30 days after surgery, and cardiovascular death was observed in 6 (18.2%) cases. Mortality was higher in patients with postoperative CVC (28.5% vs. 7.1%). This relationship remained after risk adjustment with hazard ratio 4.15 (95% CI 3.14—5.48). We estimated absolute mortality risk reduction by 0.4 (95% CI 0.3—0.5) in the absence of all CVCs. This would provide a relative mortality risk reduction by 21.3% if all CVCs were prevented. Conclusion. Under certain conditions, 1 out of 5 postoperative deaths related to CVC could be avoided. Our results provide a basis for further research.
A ray tracer model for analysis of solar concentrating systems
Authors: Nyeinga Karidewa , Okello Denis , Nydal Ole Jorgen
Published: February 2025

This study describes a 3D ray tracer model for analysis of a small-scale solar concentrating system where thermal heat is collected for cooking purposes. Emitted sun rays were traced from the source through all reflections until they intercepted with the receiver or were lost. The algorithm of the ray tracer and its implementation in MATLAB is clearly described. The ray tracer was programmed to contribute to the development of small-scale concentrating solar energy systems with integrated heat storage units. The ray tracer was demonstrated for selected cases where continuous reflecting surfaces and flat mirror-tiled surfaces were compared. Off-focus sensitivity analysis was shown and this could provide guidelines for the required solar tracking accuracy. The flux distribution on the absorber was analysed and found to be concentrated on a small area on the target for continuous reflecting surfaces and having high intensities. However, for reflectors with mirror tiles, an elongated image was formed centred on the focal point with low intensities. Small misalignment of the reflector in the order 0.2° had minimal impact on the interception ratio, but any further increase in the tracking errors caused a sudden drop in the interception ratio to zero. Results showed that there is close agreement in flux distribution and the tracking error impact on interception ratio, when compared with the literature. This model could be a useful tool when designing the reflection and absorption components of solar concentrators for complex systems with several components in a non-symmetric 3D arrangement.

Authors: Chibaya Gwarega , Naidoo Deshini , Govender Pragashnie
Published: February 2025

Introduction: Namibia signed the UNCRPD in 2007 without any reservation. The country uses a monist system prescribedin its constitution. Therefore, the UNCRPD became part of the national binding document related to disability. This paperexplores the perspectives of disability stakeholders on the implementation of the UNCRPD in Namibia.Methods: An exploratory qualitative study using in-depth interviews was conducted in Omusati and Khomas regions,Namibia. Key stakeholders in disability policy formulation and implementation were included in the study. Policymakers(n=4), implementers (n=7) and representatives from Non-Government Organisations (n=3) were recruited via purposivesampling. Data were thematically analysed.Results: The findings revealed evidence of fundamental national disability rights-enabling strategies. These includedisability rights-enabling environment, national disability policy and legislative framework, and disability rightsenforcement strategies. However, there are setbacks in implementing the UNCRPD in Namibia, such as the challengescreated due to insufficient collaborative and technical capacity, limited aggregated disability data and lack of expertiseand experience to apply UNCRPD concepts to advance disability rights.Conclusion: The disability sector may utilise policy and legislative framework and disability rights enforcement strategiesto develop an Integrated National Disability Strategy to support occupational freedom and justice for persons withdisabilities.

Two novel ecological ionic-liquid derivatives based on imidazolium (ILs), namely, 3-(2-ethoxy-2-oxoethyl)-1-phenethyl-1H-imidazol-3-ium-chloride [OE-IM+, Cl-] and 3-(4-ethoxy-4-oxobutyl)-1-phenethyl-1H-imidazol-3-ium-chloride [OB-IM+, Cl-] was studied by Electrochemical Impedance Spectroscopy (EIS), Potentiodynamic Polarization (PP), SEM/EDX analysis and theoretical calculations. It is found that the studied ionic liquids exhibit high inhibition performance for Mild steel (MS) in 1 M HCl. Hence the formation of a barrier layer that retards redox reactions and therefore prevents the corrosion process of MS. Inhibition efficiency for all the compounds increases with their concentration and follows the order [OE-IM+, Cl-] [OB-IM+, Cl-], indicating effective performance was achieved as the length of the alkyl chain attached to the imidazolium ring extended. Furthermore, DFT and MD simulations were used, revealing the impact of molecular configuration on the anticorrosive properties of these chemicals.

Students have different abilities based on their individual interests, talents, and learning styles during classroom learning. Generally, the teacher's teaching style in the classroom is implemented based on the material delivered to students. The teaching style used by the teacher must certainly align with the learning style of each student. Students' learning styles are divided into three categories: visual, kinesthetic, and auditory learning styles. The TaRL approach is a learning method that does not refer to grade levels but rather focuses on students' ability levels. The purpose of this Classroom Action Research is to increase student motivation using the Teaching at the Right Level (TaRL) approach in learning in grades X-12 at SMAN 8 Bandung. The subjects of this study were 36 students from grades X-12 at SMAN 8 Bandung. Data collection was conducted through observation, and data analysis used quantitative descriptive techniques. The results showed that student learning motivation could be assessed as follows: interval 1, which means strongly agree (10.7%); interval 2, agree (64.3%); interval 3, disagree (25%); and interval 4, strongly disagree (0%). Thus, it can be concluded that the use of the Teaching at the Right Level (TaRL) approach can effectively increase the learning motivation of grade X-12 students at SMAN 8 Bandung.

Published: February 2025

In 2021, an archaeological excavation was conducted at the Paraje de la Horca site in Borja, province of Zaragoza. During the excavation work, up to fifteen medieval Islamic burials could be identified, supposedly chronologically datable between the 8th and 12th centuries, located on a previous site from the Late Antique period. This necropolis constitutes a new example of a maqbara, which, when put in common with others in the surrounding area, can shed light on the evolution of the Andalusian funerary ritual in the middle Ebro valley.

Authors: Pérez Martín Irene , Salinas Pleguezuelo Elena
Published: February 2025

The following work focuses on the study of the Islamic ceramic from a house of the archaeological site of Barrio Andalusí (Almería), with the aim of recognising what type of ceramic ware was consumed in the 12th century in al-Mariyya. To this end, an analysis of the ceramics at the morphological, technical and decorative levels was carried out. In addition, the reference literature on Andalusi ceramics has been used to obtain more information on the dispersal and dating of the documented assemblage. This has allowed for a critical study of issues related to functionality, continuities and innovations, local production and imports, and socio-economic aspects of ceramics.
La huerta de Untinyān (Ontinyent, Valencia). Aproximación a un conjunto irrigado en el secano andalusí valenciano
Authors: Robledillo Sais Miguel
Published: February 2025

In present-day municipal district of Ontinyent (Valencia), there is an irrigated agricultural area sustained by a hydraulic system that collects its water mainlfrom the Clariano river. The origin of this periurban farmland dates back at least to the time of al-Andalus, since it already existed at the time of the arrival of the Christian troop in the 1240s. Until now, there had been no thorough investigation into this topic, nor had it been possible to provide a more precise account of its origin and evolution. Through the application of the so-called agrarian archaeology, we propose a reconstruction of the possible layout of the canals that composed this hydraulic system and an identification of the present-day plots of land within the historical spaces of Andalusí farmland. Additionally, we present a sequence of the construction of the system, offering hypotheses on the dating of its different phases. Finally, we attempt to justify why we believe that the peasant communities of Untinyān were responsible for constructing most of this landscape, locating what are possibly the settlement sites of these groups.
