ABSTRACT Introduction: Although the 2019 severe acute respiratory syndrome coronavirus 2 infection (SARS-CoV-2, COVID-19) pandemic poses new challenges to the healthcare system to provide support for thousands of patients, there is special concern about common medical emergencies, such as stroke, that will continue to occur and will require adequate treatment. The allocation of both material and human resources to fight the pandemic cannot overshadow the care for acute stroke, a time-sensitive emergency that with an inefficient treatment will further increase mortality and long-term disability. Objective: This paper summarizes the recommendations from the Scientific Department on Cerebrovascular Diseases of the Brazilian Academy of Neurology, the Brazilian Society of Cerebrovascular Diseases and the Brazilian Society of Neuroradiology for management of acute stroke and urgent neuro-interventional procedures during the COVID-19 pandemic, including proper use of screening tools, personal protective equipment (for patients and health professionals), and patient allocation.

ABSTRACT Objectives: to analyze the adequacy of maternal and child-care in prenatal care, childbirth and the puerperal period, in the public health service. Methods: longitudinal study carried out in a city in Paraná with 357 puerperal women in a public maternity ward, outpatient clinic for immediate puerperal return and home visit 42 days postpartum. Four care domains were grouped (1 - Prenatal, 2 - Maternity, 3 - Immediate puerperal return, 4 - Late puerperal return). Mean, median, standard deviation and coefficient of variance were calculated considering adequate assistance when ≥ 70%; and inadequate, inferior. Results: lowest suitability average in Domain 3 (39.37%) and highest for Domain 4 (74.82%); median of 50.00% at 3 and 76.90% at 4. The largest standard deviation, in Domain 3 (25.18%); and high coefficient of variance for 1 and 3. Conclusions: in maternal and child follow-up, rates close to adequate in maternity care and higher in late puerperal return, meanwhile prenatal and immediate puerperal return were below the recommended in the health care network.

Published: August 2020

ABSTRACT Objectives: to unveil the experience of mothers of children who had a cerebrovascular accident due to sickle cell disease. Methods: qualitative, phenomenological research based on Martin Heidegger’s philosophical framework. Ten mothers participated in the Association of People with Sickle Cell Disease of Minas Gerais. For the interpretative analysis of the reports, we performed the vague and medium understanding followed by hermeneutics. Results: the study revealed that, for the mother, the experience means remembering the diagnosis of the disease that had a significant impact. These women are in the center of care, and the consequences of stroke cause suffering. In this wandering, they seek to educate their children as close as possible to normal. Final Considerations: the study pointed out that we should look at these mothers seeking to see the multiple facets of their existence to the challenge of caring for the existential complexity of the human being.

Published: August 2020

ABSTRACT Objectives: to assess the sexual function of pregnant women and the influence of sociodemographic, obstetric, and behavioral factors on sexual dysfunction. Methods: cross-sectional study conducted with 141 pregnant women attended by the Single Health System and 120 by one private service, totaling 261 participants. A questionnaire containing sociodemographic, obstetric, and behavioral variables was applied, as well as the Female Sexual Function Index instrument, which was used to assess sexual function. Associations between variables and sexual dysfunction were made using the chi-square test, considering a statistically significant result when p < 0.05. Results: among the participants, 32.1% had sexual dysfunction, and the variables “age”, “income” and “type of health service” had an influence on sexual dysfunction. The prevalence of pregnant women was between 21 and 30 years old (p < 0.001), with an income between 1 and 2 minimum wages (p = 0.048) and used the public health system network (p = 0.000). Conclusions: the factors associated with sexual dysfunction are “young pregnant women”, “low income” and “attended in the public health service”.

Published: August 2020

ABSTRACT Objectives: to analyze the relationship between maternal age and the source of healthcare payment with mode of delivery in public and private national hospitals between the years 2012 to 2017, and the length of hospital stay. Methods: cross-sectional study of 91,894 women who had children in public and private hospitals between 2012 and 2017. Data were collected from the Diagnosis-Related Groups Brazil system and a comparative analysis was performed between patients in public care and those in supplementary healthcare. Results: in public care, the majority were vaginal deliveries and the reverse occurred in supplementary health. The proportion of cesarean sections was higher in the age group 31 to 40 years old in both services. The hospital stay was longer among women who underwent a cesarean section. Conclusions: high maternal age and the source of healthcare payment influence the mode of delivery, which interfere with the length of hospital stay.

Published: August 2020

ABSTRACT Objectives: to analyze how children with type 1 diabetes mellitus and their families explain the pathology, based on their understanding of the factors related to the discovery of diabetes, the etiology, treatment, and prognosis of the disease. Methods: qualitative methodological approach, based on medical anthropology and the narrative method. In-depth interviews were conducted with 12 families of children with type 1 diabetes mellitus attending follow-up consultations at a specialized center. The statements were subjected to inductive thematic analysis. Results: the explanatory models identified describe the families search for the clarification of the signs and symptoms that the child had. Faced with the disease, families reorganized themselves to meet new health care needs of children, such as adequate nutrition, physical exercise, and blood glucose monitoring. Final Considerations: knowing the explanatory models allows the understanding of how families give meaning to the child’s illness, favoring daily nursing care and an effective control of the disease.

Published: August 2020

ABSTRACT Objectives: to identify the female homicide profile in the city of Goiânia. Methods: a cross-sectional, descriptive study that characterized female deaths by homicide from 2008 to 2015. They occurred in Goiânia, and registered in the Mortality Information System. Cases of homicide of women aged ≥ 10 years were eligible. Other causes of death were excluded. Descriptive statistical analysis with frequencies. Results: three hundred seventy-six women died from assault, with an increase in the percentage of deaths annually. Most of the victims were young (57.5%), single (78.8%), mixed-ethnicity (61.1%) and with low education (58.4%). The most frequent means of assault was firearm (64.0%). The health districts with the highest record of female deaths due to assault were southwest, center and northwest. Conclusions: the predominant profile of women victims of femicide was young, mixed-ethnicity, single, with low level of education and living in less favored regions.

Published: August 2020

ABSTRACT Objectives: to investigate the factors associated with the mode of delivery in pregnant women in the city of Belo Horizonte. Methods: cross-sectional study developed with data from the study “Being born in Belo Horizonte: survey on childbirth and birth” carried out in seven maternity hospitals in Belo Horizonte - Minas Gerais. The final sample consisted of 1088 pregnant/postpartum women. In this study, to verify the magnitude of the association between the outcome variable and its possible determinants (exposure variables) logistic regression models were constructed to estimate the Odds Ratio. Results: increasing age, the lack of companionship, the hospital’s private financing for performing delivery and being a first-time pregnant woman increased the chance of delivery by cesarean section. Final Considerations: the knowledge of factors associated with the prevalence of cesarean sections can support reflections among health professionals about this surgical procedure in certain situations, especially when there are no precise clinical indications.

Published: August 2020

ABSTRACT Objectives: to discuss the (in)visibility of children with special healthcare needs and their families in the Primary Health Care scenario. Methods: experience report about the difficulties faced by researchers from different regions of Brazil to locate children with special healthcare needs in the scope of primary care. Results: the main reason for these children and their families to be “unknown” and, therefore, not assisted in PHC, is the fact that they are followed-up by institutions/outpatient clinics and specialized and/or public rehabilitation clinics, or even because they have private health insurance. Final Considerations: transferring care responsibility to the Primary Health Care teams to specialized and rehabilitation institutions may be related to the lack of knowledge of the care demands of this group, as well as to the relevance of care centered on rehabilitation and the specialty instead of the long-term care, one of the features of primary health care.

Nine professionals from the nursing team of a pediatric hospital unit in Porto Alegre/RS participated in the study. A sociodemographic questionnaire and semi-structured interviews were used with content analysis. Results: the results reinforced the importance of pain assessment with family participation and the need to use tools and process improvements in the training and sensitization of professionals. Final Considerations: after the study was concluded, there was a clear need to address the issue, highlighting its relevance for pain resolution in pediatric patients.

Authors: Corrêa Verônica Braga , Nunes Michelle Darezzo Rodrigues , Silveira Ana Luiza Dorneles da , Silva Liliane Faria da , Sá Selma Petra Chaves , Góes Fernanda Garcia Bezerra
Published: August 2020

ABSTRACT Objectives: to identify, in the scientific literature, the educational practices performed by nurses with the families of children and adolescents using long-term venous catheters, concerning home care. Methods: integrative review in LILACS, PubMed, SCOPUS, Web of Science and CINAHL databases, from August to September 2018. Results: we analyzed eight articles that met the inclusion criteria. The results showed that all studies are international, mostly North American and with low level of evidence. The educational practices found were home visits, production of printed educational materials, use of mannequins for simulation, creation of an educational video, and combined educational practices. Final Considerations: the care provided by families at home in the countries studied is more complex than in Brazil, and the conclusion is that Brazilian studies need to advance in publications related to this area.

Authors: Carlos Diene Monique , Campeiz Ana Beatriz , Oliveira Wanderlei Abadio de , Silva Jorge Luiz da , Wernet Monika , Ferriani Maria das Graças Carvalho
Published: August 2020

ABSTRACT Objectives: to characterize and analyze the experiences of families involved in domestic violence against children and adolescents, based on the Paradigm of Complexity. Methods: qualitative research, in which data of 15 families was collected through documentary research, open interviews and field diary. The data were analyzed through thematic analysis. Results: two categories “I don’t have it” and “I didn’t have it” emerged, revealing the historicity that marks the violence experienced in the present. They include social vulnerability, maternal burden, associated with urban violence to which families are exposed. At the same time, stories of violence by the intimate partner, as well as intergenerational violence and drug abuse have impacted the current moment. Final Considerations: nursing can contribute to attribute new meaning to violent stories woven by families, as well as to the interdisciplinary construction of perspectives and interventions that consider the multiple violence and adversities to which such a population is exposed.

Authors: Santos Fernanda Batista Oliveira , Rabelo Ana Renata Moura , França Bruna Dias , Carregal Fernanda Alves dos Santos , Marques Rita de Cassia , Silva Kênia Lara da
Published: August 2020

ABSTRACT Objectives: to know the professional trajectory of the black nurse Maria Barbosa Fernandes and to analyze elements of her professional practice based on the cultural competence model of CampinhaBacote. Methods: historical-social study with an analysis of the findings in light of the Cultural Competence model. Results: Maria Barbosa was the first black woman to earn a nursing degree at the Escola de Enfermagem Carlos Chagas (Carlos Chagas Nursing School) (1935-1938), and the documentation about her history allowed us to infer the experience of discrimination and invisibility. However, her professional trajectory was marked by careful attention to the singularities and the sociocultural reality of individuals, with an emphasis on acting in vulnerable scenarios. Final Considerations: the pairing of the theme of black women in nursing with the reference of Cultural Competence consists of an invitation to value diversity in the profession and seek to move towards care committed to overcoming inequalities, through inclusive practices and culturally sensitive care.

Published: August 2020

ABSTRACT Objective: To establish the association between initial and residual angulation of the distal interphalangeal joint (DIJ) in mallet finger treated conservatively. Methods: An observational, prospective, descriptive and analytical research developed with uncomplicated closed mallet finger patients between January and December 2017. A total of two measurements of the DIJ were done, at the initial trauma and 6 weeks after conservative treatment. All measurements were ranked according to the Crawford Classification and Relative Risk was measured. Results: In total, 43 patients were studied, in which 53.48% of outcomes obtained were excellent. The sample was divided in two groups; one with less than 30º of DIJ initial angulation, which had 28% of residual angulation. The second group with more than 30º presented 72.22% of residual angulation. The Relative Risk to present a residual angulation in patients that had 30º of DIJ initial angulation was 2.99 (CI 95%) with p = 0.0059. Conclusion: It is suggested that patients with an initial DIJ angulation more than 30º are more likely to present residual angulation with conservative treatment. Level of Evidence IV, Case series.

Published: August 2020

ABSTRACT Objective: To evaluate the complication rate of total knee arthroplasty (TKA) in octogenarian patients and identify predictive factors. Methods: The study comprised 70 octogenarians and 70 non-octogenarian patients as control group, all submitted to TKA. We analyzed the medical records of these patients, seeking for complications during the first postoperative year. Regarding the risk factors, we evaluated: age, sex, race, American Society of Anesthesiologists score, body mass index, smoking, hypertension and diabetes mellitus. Results: In the control group, the incidence of complications was 7.1%. Whereas in the octogenarian group it was significantly higher, reaching 34.3% (OR 6.8; 95% CI 2.4-19.1). We found no association to sex, skin color, and comorbidities. Age is an independent risk factor for postoperative complications. Our data may help patients to acknowledge the risks of undergoing primary TKA and physicians to assess and adjust perioperative risk. Conclusion: The incidence of postoperative complications is significantly higher in octogenarians. Level of Evidence III, Case-control study.

Published: August 2020

ABSTRACT Objective: Brachial plexus injury can lead to significant functional deficit for the patient. Elbow flexion restoration is a priority in surgical treatment. Free functional muscle transfer is an option for early or late treatment failure. This study evaluated patient characteristics and elbow flexion muscle strength after gracilis functioning muscle transfer. Methods: Medical records of 95 patients operated from 2003 to 2019 were analyzed and the following variables recorded: age, gender, nerve transfer used to motorize the gracilis muscle, time between trauma and surgery, age at surgery and elbow flexion strength after a minimum of 12 months following functioning muscle transfer. Results: 87 patients were included, averaging 30 years of age (17 to 57 years). Fifty-five achieved elbow flexion muscle strength ≥ M3 (55/87, 65%), with a mean follow-up of 37 months. The nerves used for activation of the transferred gracilis were: 45 spinal accessory, 10 intercostal, 8 median n. fascicles, 22 ulnar n. fascicles and 2 phrenic nerves. Conclusion: Functional muscle transfer is a viable surgical procedure for elbow flexion in chronic traumatic brachial plexus injuries in adults. Level of Evidence II, Retrospective study.

Published: August 2020

ABSTRACT Objective: To compare postoperative radiographic outcomes of Schatzker type V and VI tibial plateau fractures treated with double-plate or single lateral locked plate. Methods: Sixty-three patients operated from December 2011 to February 2016 were selected, 47 from the double-plate group and 16 from the single lateral locked plate group. Minimum follow-up for all patients was 6 months. Fracture reduction evaluation was based on radiographic parameters: joint reduction, sagittal alignment, coronal alignment, and condylar width. Results: Radiographic evaluation showed no statistical difference in the immediate or late postoperative periods. Conclusion: Despite the reduced sample, this study is aligned with current results published in the medical literature. The severity of Schatzker type V and VI tibial plateau fractures can be minimized by the correct indication for the implant regarding fracture morphology. Level of Evidence III, Retrospective comparative study.

Published: August 2020

ABSTRACT Objective: To evaluate if the levels of serum total protein and serum albumin are risk factors for surgical complications of free flap limb reconstruction. Methods: Consecutive inclusion of all patients undergoing microsurgical flaps for limb reconstruction of complex injuries. We recorded epidemiological and laboratory data, including total proteins and fractions, for descriptive and analytical statistics. Results: Our study analyzed one microsurgical flap from 35 patients that underwent complex injuries of the limbs. In total, 23 patients were men, and mean age of all patients was 35 years. After statistical analysis, no influence of pre or postoperative hypoalbuminemia was observed on the incidence of complications. Patients with hypoalbuminemia had a higher length of stay than those with normal albumin levels (p = 0.008). Conclusion: We observed that 71% of patients had hypoalbuminemia in early postoperative period and we suggest a nutritional support for patients requiring complex traumatic limb reconstruction. Hypoalbuminemia in patients subjected to microsurgical flaps for the treatment of complex traumatic limb injuries did not influence the complications that required surgical reintervention; However, it was associated with prolonged hospital stay. Level of Evidence II, Retrospective study.

Authors: Sambuy Marina Tommasini C. , Nakamoto Hugo A. , Bolliger Neto Raul , Mattar Jr. Rames , Rezende Marcelo R. , Wei Teng Hsiang
Published: August 2020

ABSTRACT Objective: Dupuytren’s disease is a genetic disorder related to the proliferation of myofibroblasts. The pluripotent property of stem cells present in adipose tissue inhibits myofibroblast proliferation. Our study sought to evaluate the effect of stem cell-rich fat grafts in patients that underwent limited fasciectomy. Methods: We studied 45 patients, in a single-blind, prospective, randomized clinical trial. All patients underwent limited fasciectomy. In one group, fat graft was injected. Results: The total passive extension deficit results did not exhibit a significant difference. Fat group exhibited worse functional score at 6 months and 1 year postoperatively, such as higher complication rates (43%), when compared with control group (8%), and more pain at 6 weeks follow-up. Conclusion: Fat grafting associated with limited fasciectomy promotes worse functional results compared to conventional limited fasciectomy in the short term. However, long-term results and recurrence rates should be further assessed. Level of Evidence II, Prospective comparative study.
Sympatry between species of Juliomys (Rodentia: Sigmodontinae) along an altitudinal gradient in the Serra da Bocaina National Park

Published: August 2020

Abstract The altitudinal gradient found in the Atlantic Forest may play a role in establishing sympatry areas between congeneric species of sigmodontine rodents. For some genera with cryptic species, the elucidation of spatial patterns of distribution may be useful to understand reproductive isolation and speciation patterns, as well as spatial and temporal factors determining the boundaries of species’ geographical distributions. Here we evaluated the occurrence of sympatry between Juliomys species along an altitudinal gradient in the Serra da Bocaina National Park (SBNP). Additionally, we review the occurrence of J. rimofrons and add new records of species occurrence in the SBNP, aided by karyological and molecular data. The study was carried out at four sites in the SBNP, which ranged between 770 and 1,200 m a.s.l. We captured 24 Juliomys specimens. Six out of 24 specimens were collected and karyotyped. For J. pictipes, the karyotype had a 2n of 36 and a FN of 34, and for J. ossitenuis 2n of 20 and FN of 36. Seventeen out of 24 Juliomys specimens were used in the cytochrome b phylogeny: 12 specimens grouped with J. pictipes and five with J. ossitenuis. Additionally, a specimen previously identified as J. rimofrons (MN 77793) clustered together with J. pictipes. Juliomys pictipes and J. ossitenuis were found in sympatry in two out of four sites in altitudes higher than 1,000 m a.s.l.. Our karyological and molecular data provided the detection of two Juliomys species in the SBNP for the first time (J. pictipes and J. ossitenuis) and disregarded the previous record of J. rimofrons. Our record of sympatry between J. pictipes and J. ossitenuis represents the fifth known record of sympatry between these species up to date.
First record of plastic ingestion by an important commercial native fish (Prochilodus lineatus) in the middle Tietê River basin, Southeast Brazil
Authors: Urbanski Bruna Q. , Denadai Ana C. , Azevedo-Santos Valter M. , Nogueira Marcos G.
Published: August 2020

Abstract This is the first study to report the plastic ingestion by Prochilodus lineatus in Brazilian fluvial ecosystems. We examined 32 individuals collected in two contrasting lotic environments: the highly polluted Tietê River and its much less degraded tributary, Peixe River. Most individuals, 71.88%, contained plastic in their digestive tract, with averages of 3.26 and 9.37 particles per individual in the tributary and main river, respectively. The blue color was predominant among the observed plastic particles and size ranged from 0.18 to 12.35 mm. Plastic ingestion must be accidental, predominantly, since the species has an iliophagous eating habit. As this species is regionally the most important fishery resource, potential adverse effects of this type of contamination may be transferred to human consuming populations. Mitigation measures against pollution are urgent in the Tietê River basin.

Análise da pressão em recipientes de plástico devido à reação do ácido acético com bicarbonato de sódio
Authors: Lapolli E.L. , Coelho Sara E.
Published: August 2020

Resumo Neste artigo, foi desenvolvido uma expressão, a partir de primeiros princípios, para o aumento da pressão provocada pelo dióxido de carbono, resultante da reação entre o bicarbonato de sódio e o vinagre no interior de uma garrafa de polietileno tereftalato (PET). Esta reação, neste tipo de recipiente, é comumente utilizada em competições de lançamento de foguetes no âmbito nacional por estudantes de ensino médio. A motivação dá-se pela segurança, controle e desperdício de material, já que os estudantes realizam os testes sem controle sobre o parâmetros físicos e químicos. Um outro fato, é que as duas equações existentes, descrevem bem o comportamento da pressão em recipientes rígidos fechados até 60 PSI, o qual é metade do valor da pressão de trabalho de uma garrafa PET do tipo reciclável. A expressão, aqui estabelecida, apresenta concordância com a equação empírica até 160 PSI, e por consequência, com os dados experimentais.
Órbitas esféricas de fótons ao redor de um buraco negro de Kerr

Published: August 2020

Resumo Buracos negros são regiões aprisionadas do espaço-tempo. A sua inexorável atração gravitacional determina que nada – nem mesmo a luz – pode escapar desta região. Logo, um buraco negro não pode ser observado diretamente. Tem de ser estudado pelo modo como influencia o movimento das partículas de matéria e os raios de luz ao seu redor. Estas trajetórias são determinadas (em uma certa aproximação) pelas geodésicas da geometria do buraco negro. Em particular, geodésicas nulas – aquelas que raios luminosos seguem – possuem considerável interesse astrofísico: representam como a radiação emitida ao redor do buraco negro, ou proveniente de fontes longínquas, é distorcida pelo buraco negro. Neste trabalho apresentamos as equações de movimento de raios de luz na geometria de Kerr, que descreve um buraco negro com rotação, utilizando a teoria de Hamilton-Jacobi. Em seguida, analisamos as condições de existência das órbitas esféricas de fótons ao redor do buraco negro. Estas órbitas, representando fortes encurvamentos da luz, são a chave para determinar a aparência ótica do buraco negro. Por fim, por meio de métodos computacionais, apresentamos graficamente algumas destas trajetórias.

Authors: Faria Marina Vilela Brandão Leite , Botelho Maria Izabel Vieira , Silva Edson Arlindo
Published: August 2020

Resumo: O Programa Bolsa Família é uma política pública social que pode ser acessada tanto pela população rural quanto urbana. O objetivo deste estudo foi refletir em que medida o acesso a este programa, adotado para combate à pobreza, pode representar um fator estruturante de possibilidades de estratégias de diversificação dos meios de vida. Trata-se de uma pesquisa qualitativa, que utilizou como fontes de informação a revisão bibliográfica e a análise documental, bem como entrevistas semiestruturadas realizadas com representantes de organizações e com representantes de unidades familiares beneficiadas da zona rural do município de Luminárias, estado de Minas Gerais. A partir do acesso ao programa, verificou-se a manutenção de aspectos relacionados à vida digna, viabilizados principalmente por meio do consumo e da minimização de vulnerabilidades e privações, principalmente das mulheres. Estes são aspectos fundamentais para superação da pobreza e para viabilização de estratégias de diversificação dos meios de vida. O estudo sugere outras reflexões relacionadas a fatores estruturantes de diversificação dos meios de vida, como: o modelo de desenvolvimento rural, relações entre o rural e o urbano e a qualidade dos serviços acessados por meio das condicionalidades do programa.

Resumo: Neste artigo, buscou-se estudar as transmissões de volatilidade de preços entre commodities agrícolas brasileiras, mais especificamente o etanol, o açúcar e a soja. Fez-se o uso de dados diários entre 25 de janeiro de 2010 e 28 de dezembro de 2018, obtidos no CEPEA. Inicialmente, estimou-se um modelo de vetor de correção de erros para filtrar as séries de sua relação de longo prazo e, na sequência, modelar suas respectivas volatilidades sem a interferência do comovimento entre as médias dos preços por meio da versão multivariada do modelo de heterocedasticidade condicional autorregressivo generalizado Baba-Engle-Kraft-Kroner. Os resultados sugerem que os preços do etanol, da soja e do açúcar estão relacionados à dinâmica de equilíbrio de longo prazo e de curto prazo, mas não é possível concluir que exista transbordamento de volatilidade entre os preços analisados. Conclui-se que a preocupação com o etanol como causa da instabilidade dos preços de alimentos não pode ser justificada pelos resultados encontrados.

Abstract: Agribusiness, including all its dimensions, is the largest economic sector in Brazil and plays a fundamental role in the development of the country's economy. About one-fourth of the Brazilian Gross Domestic Product (GDP) is composed of agribusiness. The objective of this article is to evaluate the participation of agribusiness in the economy of an important region of Brazil from 2010 to 2015. The evaluation was carried out through the decomposition of GDP, with an analysis of aggregate inputs, agro-livestock products, industrialization, and services. This article presents three main contributions to the understanding and composition of agribusiness GDP. The novelty of this article lies in the fact that it is the first work in the literature to present the steps of the methodology for calculating GDP in a region representing Brazilian agribusiness, considering its aggregates and relating the generation of taxes and other factors. In addition to the empirical and methodological contributions, this article highlights the relevance of agribusiness to the Brazilian economy, which, in turn, has relevance to global agribusiness.

Abstract: Successive reforms in the Common Agricultural Policy (CAP), enlargements of the European Union (EU) and pressures in the public budget increase the need for empirical studies to assess the role of subsidies in shaping firms’ performance and, hence, to support policy-makers decisions and decision-making in the productive sector. This paper assesses whether subsidies affect the technical efficiency of 1,943 Portuguese agribusiness firms over 2007-2015. By applying stochastic frontier models and fixed-effects models, to calculate the average efficiency of these firms, the results show different effects of subsidies among agribusiness sectors. The stochastic frontier model revealed that the subsidies have a positive and significant impact on the technical efficiency of three sectors, animal production, manufacture of food, and manufacture of paper. Further, except for firms in the forestry and logging sector, Portuguese agribusiness firms had higher average efficiency levels when subsidised, which provides evidence that subsidies could be important and contribute positively to the technical efficiency of Portuguese firms.

ABSTRACT The water deficit in arid and semiarid regions and the high cost of fertilizers are factors for the study of application of sewage on agricultural crops. Therefore, the objective of this study was to evaluate the effect of application of different doses of treated sewage from the tertiary treatment (TS-3), and mineral fertilizer on the yield and production components of common bean plants. The experiment was conducted in Janaúba, MG, Brazil, using a randomized block design, with four repetitions, in a split-plot scheme, with five treatments in the plots consisting of potassium (K2O) applications at the dose required by common bean plants via clear water + 40 kg ha-1 of K2O mineral (Control), and TS-3 applications supplying 20, 40, 60 and 80 kg ha-1 of K2O, and two cultivars in the subplots, BRS-MG-Madreperola and Ouro Negro. The cultivar Ouro Negro was more responsive than the cultivar BRS-MG-Madreperola to the different TS-3 doses and mineral fertilizer regarding their leaf, stem, and shoot dry weights, and their ratios. However, the highest doses of K2O via TS-3 affected negatively the grain yield in common bean plants. The dose of 20 kg ha-1 of K2O via TS-3 is the best dose for common bean plants.

ABSTRACT The soil is an important component in the biogeochemical cycling of carbon (C) and nitrogen (N). The objective of this study was to evaluate the changes caused by different types of land use on the C and N stocks in areas of Cerrado at different depths: area under conventional tillage, no-tillage, grazing, eucalyptus and area under native vegetation of Cerrado in the municipality of Luis Eduardo Magalhães, BA, Brazil. The highest C content was found for no-tillage area in the surface layer up to 10 cm; however, there was a decrease in its content along the depths. Areas under no-tillage had lower values of C in the surface layer (0-5 cm) and below 20 cm. Among these, C stocks were significantly lower compared to the use of grass and eucalyptus at the depth of up to 40 cm. Considering the depth of 0-60 cm, the highest C stock was found in areas under native vegetation, 62.81 Mg ha-1, followed by the area under cultivation with eucalyptus, 60.70 Mg ha-1. The lowest C stocks were found in areas under conventional use, 44.87 Mg ha-1. Conventional planting reduced N stocks by up to 61 and 56% when compared to areas under native Cerrado vegetation and eucalyptus plantations, respectively, both at a depth of up to 10 cm. Therefore, land use practices such as eucalyptus cultivation and no-tillage contribute to C and N storage over time.

ABSTRACT The objective of this study was to estimate the general combining ability (GCA) and specific combining ability (SCA) of cotton genotypes subjected to water stress, based on fiber quality traits. Irrigated cotton plants were grown in the dry season in the Northeast region of Brazil and subjected to 23 days without irrigation at the beginning of the flowering stage. GCA and SCA analyses were based on the partial diallel model. Significant differences were found for GCA for all traits, with predominance of additive effects. The crossing between the genotypes FM-966 and CNPA-5M was the most promising hybrid combination, showing great potential for improvements in fiber quality in environments subjected to water stress, such as the Semiarid region of the Northeast of Brazil.

ABSTRACT This research aimed to monitor and evaluate air-conditioned trucks transporting day-old chicks, in various shifts of travel, through general packet radio service (GPRS) technology to provide real-time thermal control for poultry industry managers. The Control-Broilers equipment used were GS-105 and the Monitorar Platform. GS-105 is composed of sensors, a microprocessor, GPRS, and batteries. The Monitorar Platform provided nine applications that acted in coordination with web technology RESTful services. Twenty-eight chick transports were evaluated and monitored using the Control-Broilers. Truck routes were supervised by two researchers to ensure real-time data transmission through laptops and smartphones. Three air-conditioned trucks were used during two of days shifts. The vehicles had the same dimensions, but the routes, travel times, and load densities varied. Measurements of the air temperature, relative humidity, and specific enthalpy inside the trucks were recorded every minute. The experimental design was entirely randomized in a 3 × 2 factorial scheme, which represented the three trucks (CL, CA and JA) in two transport shifts (day and night), containing four repetitions (travel).The air-conditioned trucks transporting day-old chicks presented a 92.85% efficiency for real-time data transmission using GPRS technology. The trucks during the travel shifts did not provide thermal homogeneity in chick loads. The night shift presented worse thermal conditions.

ABSTRACT Solanum paniculatum L. (jurubeba) is among the numerous medicinal plants used by the Brazilian population, and the use of its leaves is quite popular, in the form of tea, as a remedy against hangovers after excessive consumption of alcohol and food, besides being used in the form of ointments as healing agent and also in the treatment of liver and digestive problems. Leaves of medicinal plants usually have a high moisture content, requiring its reduction by drying, so that the product can be stored safely until its processing. The objective of this study was to evaluate the drying kinetics of jurubeba leaves and to determine the effective diffusion coefficient and activation energy during drying. Jurubeba leaves were dried at different air temperatures (30, 40, 50, 60 and 70 °C) and speed (0.4 and 0.8 m s-1). The Midilli model satisfactorily fitted to the observed data of drying of jurubeba leaves for all air conditions. Increasing the drying air temperature and speed reduced the drying time and increased the effective diffusion coefficient. For the air temperature range from 40 to 70 °C, as the drying air speed increases, the activation energy for the drying of the jurubeba leaves is reduced.
