Abstract The geographical distribution of sand flies in Brazil has been the subject of some studies, yet there is no information about the phlebotomine fauna in João Pessoa, State of Paraíba, Brazil. The aim of this work is to evaluate the occurrence and distribution of sand flies in the Atlantic forest fragments and to evaluate a possible dispersion in 06 nearby districts. Light traps were used during three consecutive nights, supplemented by an aspirator during the dry period and rainy season. A total of 222 sand flies were found, 143 (130 males and 13 females) in the Atlantic forest, and 79 in urban areas. During the entire dry season, three species of phlebotomine sand flies were recorded in 11 forest fragments, Lutzomyia longipalpis, Lu. migonei and Lu. whitmani. During the rainy season, only Lu. longipalpis was found. This was the only species identified in the studied neighborhoods during both seasons. The differences in diversity of sand flies encountered between natural habitats and urban areas may thus be correlated mostly with adaptations to particular habitats and availability of food. One species (Lu. longipalpis) appears to be rapidly adapting to urban areas because of deforestation.

Aromatic amines are important intermediates in the industry to produce a wide array of products, and the reduction of aromatic nitro compounds is the main methodology for their preparation. Considering this fact, the objective of this review is to describe the development of sustainable methodologies for the reduction of aromatic nitro compounds for their respective amines from 2017 to 2020. Thus, throughout the text, the reaction conditions and the various reagents, solvents and catalysts used in the synthesis of aromatic amines are presented, along with the main advantages of the methodologies described.

Objectives: Past suicide attempt (SA) is one of the most important risk factors for suicide death. An ideation-to-action framework posits that impulsivity, potentially traumatic events, and mental disorders also play a role in increasing suicide risk. This study aimed to assess the association between trait impulsivity, lifetime exposure to trauma, and post-traumatic stress disorder (PTSD) with SA in a sample of Brazilian college students. Methods: A total of 2,137 participants filled self-reported questionnaires consisting of a sociodemographic and clinical questionnaire, Trauma History Questionnaire, Post-Traumatic Stress Disorder Checklist – Civilian version, and Barratt Impulsiveness Scale. Results: Our findings suggest that trait impulsivity may be interpreted as exerting a distal effect on SA, even in the presence of other variables – such as trauma history, psychological neglect, and PTSD – which also increase the odds of SA. High and medium levels of impulsivity, history of trauma, and PTSD increased the likelihood of SA. Conclusions: Intervention strategies to prevent SA may target trait impulsivity and exposure to traumatic experiences.

Abstract The Nobel Prize in Chemistry 2019 recognized the importance of Li-ion batteries and the revolution they allowed to happen during the past three decades. They are part of a broader class of electrochemical energy storage devices, which are employed where electrical energy is needed on demand and so, the electrochemical energy is converted into electrical energy as required by the application. This opens a variety of possibilities on the utilization of energy storage devices, beyond the well-known mobile applications, assisting on the decarbonization of energy production and distribution. In this series of reviews in two parts, two main types of energy storage devices will be explored: electrochemical capacitors (part I) and rechargeable batteries (part II). More specifically, we will discuss about the materials used in each type of device, their main role in the energy storage process, their advantages and drawbacks and, especially, strategies to improve their performance. In the present part, electrochemical capacitors will be addressed. Their fundamental difference to batteries is explained considering the process at the electrode/electrolyte surface and the impact in performance. Materials used in electrochemical capacitors, including double layer capacitors and pseudocapacitive materials will be reviewed, highlighting the importance of electrolytes. As an important part of these strategies, synthetic routes for the production of nanoparticles will also be approached (part I).

Abstract In the second part of the review on electrochemical energy storage, the devolvement of batteries is explored. First, fundamental aspects of battery operation will be given, then, different materials and chemistry of rechargeable batteries will be explored, including each component of the cell. In negative electrodes, metallic, intercalation and transformation materials will be addressed. Examples are Li or Na metal batteries, graphite and other carbonaceous materials (such as graphene) for intercalation of metal-ions and transition metal oxides and silicon for transformation. In the positive electrode section, materials for intercalation and transformation will be reviewed. The state-of-the-art on intercalation as lithium cobalt oxide and nickel containing oxides will be approached for intercalation materials, whereas sulfur and metal-air will also be explored for transformation. Alongside, the role of electrolyte will be discussed concerning performance and safety, with examples for the next generation devices. Finally, a general future perspective will address both electrochemical capacitors and batteries.

Resumen Este estudio evaluó la contribución de la nutrición con potasio (K) y la aplicación de las láminas de las aguas residuales al rendimiento agronómico del algodón colorido. Los tratamientos consistieron en cinco láminas de riego (50, 75, 100, 125 y 150% de la evapotranspiración del cultivo - ETC) y cinco dosis de K (0, 50, 100, 150 y 200% de la recomendación del cultivo). Fue también utilizado un control absoluto de riego con lámina 100% de la ETC y fertilizado con una recomendación de 100% N-P-K. Así como los tratamientos el control también tuvo cuatro repeticiones. La altura de la planta, el diámetro del tallo, el área de la hoja y la acumulación de materia seca del algodón en los brotes se evaluaron a los 130 días después de la emergencia (DAE), mientras que el peso del algodón semilla, se evaluó a 135 DAE. Los resultados indican que el uso de aguas residuales domésticas tratadas para compensación del 100% de ETC promueve un mayor aumento de peso y crecimiento del algodón colorido sin la necesidad de fertilización con K, lo que evidencia el potencial de las aguas residuales para el algodón colorido para una agricultura sostenible.

Abstract This study evaluated the contribution of potassium (K) nutrition and application of wastewater depths to the agronomic performance of colored cotton. Treatments consisted of five irrigation depths (50, 75, 100, 125 and 150% of crop evapotranspiration - ETC) and five K doses (0, 50, 100, 150 and 200% of the recommendation for the crop) and an absolute control irrigated with 100% ETC water depth and fertilized with 100% N-P-K recommendation. Each treatment and the control had four replicates. Plant height, stem diameter, leaf area and shoot dry matter accumulation of cotton were evaluated at 130 days after emergence (DAE), whereas seed cotton weight was evaluated at 135 DAE. Our findings indicate that the use of treated domestic sewage for 100% ETC replacement promotes greater gains of weight and growth in colored cotton without the need for K fertilization, evidencing the potential of wastewater for colored cotton for sustainable agriculture.

RESUMO A utilização de esgotos domésticos tratados na agricultura mostra-se promissora por apresentar nutrientes essenciais para culturas, particularmente, no algodoeiro. Nesse sentido, o conhecimento das trocas gasosas foliares auxilia no entendimento de estratégias utilizadas pelas plantas sob manejos de água e nutrientes, uma vez que, os processos fisiológicos são diretamente influenciados por esses fatores. Diante do exposto e com o desígnio de servir como referência na investigação de respostas de plantas do algodoeiro aos fatores abióticos, objetivou-se avaliar o efeito da irrigação com água de esgoto tratado e doses de potássio nas trocas gasosas do algodoeiro colorido no semiárido pernambucano. O experimento foi em blocos casualizados em esquema fatorial com cinco lâminas de irrigação (50, 75, 100, 125 e 150% da ETc) e cinco doses de potássio (0, 50, 100, 150 e 200% do recomendado para a cultura) com quatro repetições. Os maiores valores para condutância estomática, transpiração, assimilação líquida, concentração intercelular de CO2 e eficiência de carboxilação foram obtidos nas plantas irrigadas com 110, 99, 117, 150 e 113% da ETc, combinadas às doses de potássio relativas a 96, 113, 97, 100 e 100% da recomendação para a cultura. O aumento das lâminas de irrigação proporcionou, também, a maior difusão de CO2 às plantas. A maior eficiência instantânea no uso de água foi na lâmina de 150% da ETc sem adubação potássica. Pelos dados da interação lâminas de irrigação versus doses de potássio, a dose mais eficiente de potássio ao algodoeiro colorido depende da lâmina de irrigação aplicada.

ABSTRACT The use of treated domestic wastewater in agriculture is promising because it contains essential nutrients for crops, especially for cotton plants. Information on leaf gas exchanges helps to understand the responses of plants to different water and nutrient managements, since they directly affect physiological processes. Thus, the objective of this study was to evaluate the effect of potassium fertilization and irrigation with treated wastewater on the gas exchange of naturally colored cotton plants grown in the semi-arid region of the state of Pernambuco, Brazil, providing a reference for evaluations of responses of cotton plants to abiotic factors. The experiment was conducted in a randomized block design, in a 5 × 5 factorial arrangement, with four replications. The treatments consisted of five potassium rates (0, 50, 100, 150, and 200% of the recommended rate for the crop) and five irrigation depths (50, 75, 100, 125, and 150% of the evapotranspiration of the crop). The highest stomatal conductance, transpiration, net assimilation rate, intercellular CO2 concentration, and carboxylation efficiency were found in irrigated plants with 110, 99, 117, 150, and 113% of ETc, combined with the potassium rates of 96, 113, 97, 100, and 100% of the recommendation rate for the crop, respectively. The increase in irrigation depths increased the diffusion of CO2 of the plants. The highest instantaneous water-use efficiency was found with the irrigation of 150% of ETc without potassium fertilization. According to the interaction between irrigation depths and potassium rates, the most efficient potassium rate for naturally colored cotton depends on the irrigation depth applied.

OBJECTIVES: To evaluate the safety and efficacy of endovascular intervention with angioplasty and stent placement in patients with transplant renal artery stenosis. METHODS: All patients diagnosed with transplant renal artery stenosis and graft dysfunction or resistant systemic hypertension who underwent endovascular treatment with stenting from February 2011 to April 2016 were included in this study. The primary endpoint was clinical success, and the secondary endpoints were technical success, complication rate and stent patency. RESULTS: Twenty-four patients with transplant renal artery stenosis underwent endovascular treatment, and three of them required reinterventions, resulting in a total of 27 procedures. The clinical success rate was 100%. All graft dysfunction patients showed decreased serum creatinine levels and improved estimated glomerular filtration rates and creatinine levels. Patients with high blood pressure also showed improved control of systemic blood pressure and decreased use of antihypertensive drugs. The technical success rate of the procedure was 97%. Primary patency and assisted primary patency rates at one year were 90.5% and 100%, respectively. The mean follow-up time of patients was 794.04 days after angioplasty. CONCLUSION: Angioplasty with stent placement for the treatment of transplant renal artery stenosis is a safe and effective technique with good results in both the short and long term.

OBJETIVO: O objetivo deste trabalho foi auditar a real quantidade de fluídos cristalóides infundidos por via intravenosa em pacientes submetidos a operações abdominais de grande porte num hospital universitário. MÉTODOS: Computou-se a carga hídrica total (CHT) de fluidos cristalóides intravenosos infundida diariamente do 1º ao 4º dia de PO em 31 pacientes submetidos à operações de grande porte. Comparou-se a CHT com a carga hídrica prescrita (CHP) pelo médico. A CHT foi definida como a somatória da CHP acrescida de diluentes e medicações intravenosas. O protocolo do serviço recomendava a hidratação venosa no peri-operatório entre 30 e 50 mL/Kg/dia em pacientes com prescrição de jejum oral. A comparação entre CHT e CHP foi realizada em todos os dias de pós-operatório pelo teste t pareado. Estabeleceu-se em 5% o nível de significância estatística. RESULTADOS: A CHT infundida do 1º ao 4ºdia de pós-operatório foi de 12,8 (6,4-17,5) L. Desse total, 9,5 litros (74,3%) corresponderam a CHP e 3,3 L (25,7%) a diluentes e medicações venosas. Em todos os dias de pós-operatório a CHT foi significativamente maior que a CHP (p<0.001). Até o 3º dia de PO os pacientes receberam uma CHT superior a 50 mL/kg/dia. CONCLUSÃO: Conclui-se que a prescrição médica não contém o real volume de fluidos cristalóides intravenosos infundido. O volume de diluentes e medicações intravenosas pode chegar a 25% da carga hídrica prescrita.

OBJECTIVE: The aim of this study was to audit the real amount of crystalloid intravenous fluids infused in patients underwent major abdominal operations in a University hospital. METHODS: The whole intravenous crystalloid fluid load (CHT) infused from the 1st to the 4th postoperative day in 31 patients underwent major abdominal operations was registered. This amount was compared to the volume daily prescribed (CHP) by the physician. CHT was defined as the sum of CHP plus diluents and intravenous drugs received by the patients. Hydration protocol of the service was 30-50 mL/Kd/day for patient with nil per os prescription. Comparisons between CHT and CHP was done in each postoperative day using paired T test. A 5% level was established as significant. RESULTS: CHT summed from 1st to 4th PO days was (mean and range) 12.8 (6.4-17.5) L corresponding to 9.5 L (74.3%) of CHP and 3.3 L (25.7%) of diluents and intravenous drugs. In each postoperative day, CHT was significantly greater than CHP (p<0.001). Until the 3rd PO day patients received a CHT greater than 50 mL/Kg/day. CONCLUSION:. Medical prescription does not contain the real amount of crystalloid intravenous fluids infused. Diluents and intravenous drug may reach 25% of the intravenous fluids load.

A pesquisa foi realizada com o objetivo de avaliar a qualidade sanitária de sementes de soja cv. Coodetec 217, colhidas por duas colhedoras operando em velocidades e pontos de coleta distintos. O delineamento foi inteiramente casualizado, no esquema fatorial 2x2x2. Os tratamentos foram constituídos por duas máquinas Massey Ferguson (MF 2003 e MF 2004), duas velocidades (4 e 7 Km.h¹) e dois pontos de coleta (tanque graneleiro e saída do tubo de descarga). A sanidade foi avaliada pelo método do papel de filtro, com quatro repetições de 50 sementes. Houve interação significativa para os fatores colhedora e ponto de coleta para a incidência de Penicillium sp. e Fusarium sp., entre colhedora e velocidade para Aspergillus spp., e, entre velocidade e ponto de coleta para Penicillium sp.. A presença de fungos associados às sementes, principalmente, Cladosporium sp. e Fusarium sp., independe do tipo de colhedora. Uma menor contaminação fúngica é observada nas sementes coletadas na saída do tubo de descarga à 4 Km.h-1. Para Fusarium sp., Aspergillus spp., e Penicillium sp. existe uma dependência dos fatores sobre suas incidências nas sementes da cultivar analisada, sob as condições estudadas.

The objective of this study was to evaluate the health quality of soybean seeds cv. Coodetec 217, in two harvesters operating at different speeds and in different collection places in the machine. The treatment consisted of two machines (Massey Ferguson, 2003 and Massey Ferguson, 2004), two speeds (4 Km.h-1 and 7 Km.h-1) and two collection places (grain tank and unloading exit). The analyses were realized at the Laboratory of Phytopathology at FCAV/UNESP, Campus of Jaboticabal, SP, Brazil. The seeds were analyzed by the Blotter test with four repetitions of 50 seeds. There was significant interaction for the factors machines and collection places for the incidence of Penicillium sp. and Fusarium sp., among machines and speed for Aspergillus spp., and among speed and collection places for Penicillium sp.. The presence of fungi associated to the seeds, mainly, Cladosporium sp. and Fusarium sp. did not depend on the machine type. Smaller contamination in general was verified in the seeds collected from the unloading exit and at the speed of 4 Km.h-1. For Fusarium sp., Aspergillus spp., and Penicillium sp. there was a dependence of the factors on their incidences in the seeds of the cultivars analyzed, under the studied conditions.
