Physical and chemical characterization of yacon (Smallanthus sonchifolius) roots cultivated with different doses of potassium fertilization

The already marked tendency for functional food consumption, low in calories, and with biologically active properties, has been increasing. In this scenario, yacon tuberous roots, with high levels of nutraceutical fructooligosaccharides, gain importance. However, these nutraceutical properties depend on fertilization management. Thus, our study aims to evaluate different doses of potassium fertilization on the physicochemical characteristics of yacon roots. The experimental design consisted of randomized blocks, with 4 replications and 5 treatments: four doses of potassium fertilization (50%; 100%; 150%; 200%) of the reference value, corresponding to 178.7 kg.ha-1; 357.4 kg.ha-1; 536.1 kg.ha-1; 714.8 kg.ha-1 of potassium chloride – (KCl), and a control (soil without fertilization). The chemical features evaluated were pH, total titratable acidity, soluble solids, conductivity, turbidity, moisture and ashes. The texture profile was analyzed through toughness, adhesiveness, cohesiveness, chewability index, elasticity, and gooeyness. Most of the variables were influenced by potassium soil fertilization. Only turbidity, conductivity and gumminess showed no response to the applied doses, not fitting the tested models. Potassium fertilization improved both chemical (higher levels of soluble solids and less acidity) and physical characteristics (less hardness, chewability, cohesiveness, and adhesion) of yacon tuberous roots, bringing greater quality to the final product. Highlights Yacon is considered a prebiotic food. Several immunostimulatory characteristics promote antimicrobial, anti-inflammatory, and antioxidant activity. Potassium is associated with root size, shape, texture, color, flavor, acidity, nutrient transport resistance, nutritional value, and even market value. Texture constitutes an important factor and quality criterion for the sensory acceptance of food. Thus, the results obtained show that potassium fertilization improves both physical and chemical characteristics of yacon roots. The best results were observed with the maximum dose of potassium fertilization (357.4 kg.ha-1 of KCl).The already marked tendency for functional food consumption, low in calories, and with biologically active properties, has been increasing.

Use of the queuing theory for analysis and dimensioning of the system of attendance in a lottery house in the municipality of Marabá/PA

It is almost inevitable that we find queues in customer service systems, and the Lottery Houses are a great example of this situation, since they offer several services with high demand. Given the current fierce competition in the economy and the growing need to win customers and keep them faithful, in this case study the queuing theory was applied to analyze the agglomeration in Lottery houses in order to verify the sizing and measures of the service system. For this purpose, data were collected such as λ (average arrival rate) and μ (average attendance rate) that later generated parameters in order to know the behavior of the queue and the attendance at the place. The results showed an adequate and stable service system in which the two boxes of the establishment are sufficient to meet the needs of its clients for the analyzed period. For future research it is recommended to apply the concepts of queue theory in other periods of operation of the organization so that the analyzes of the current system are closer to the real.É quase que inevitável nos depararmos com filas em sistemas de atendimento, e as Casas Lotéricas são um grande exemplar dessa situação já que oferecem diversos serviços possuindo uma alta demanda. Tendo em vista a competição acirrada presente na economia nos dias atuais e a necessidade crescente de conquistar clientes e mantê-los fiéis, neste presente estudo de caso foi aplicada a teoria das filas para analisar a aglomeração em casas Lotéricas a fim de verificar o dimensionamento e medidas de desempenho do sistema de atendimento. Para tal objetivo, foram feitas coletas de dados como λ (taxa média de chegada) e μ (ritmo médio de atendimento) que posteriormente geraram parâmetros a fim de conhecer o comportamento da fila e do atendimento no local. Os resultados evidenciaram um sistema de atendimento adequado e estável no qual os dois caixas do estabelecimento são suficientes para atender as necessidades dos seus clientes para o período analisado. Para pesquisas futuras recomenda-se a aplicação dos conceitos de Teoria das filas nos demais períodos de funcionamento da organização para que a as análises do sistema atual sejam mais próximas do real.São Cristóvão, S

Lessons Learned During Testing Through Commissioning of the Joint Brazil-US SPORT Mission

SPORT is an international partnership mission between Brazil and the United States to study ionospheric space weather processes that occur at low latitudes. Operating a CubeSat on orbit is certainly one of the most exciting milestones of a CubeSat project, but it is only a part of the mission. To be able to achieve this milestone the efforts of the engineering team were focused late in the project on the integration, testing, and delivery followed by the on-orbit commissioning of the observatory. This paper details the major events and lessons learned by the SPORT team during these phases of the project. SPORT experienced a failure of the battery subsystem during environmental testing followed by physical damage during shipping from Brazil to the United States for Launch. However, more than pointing out these problems, solutions, and lessons learned, this paper explains how the international team worked to overcome the issues and finalize the observatory for delivery and launch. After release from the ISS the SPORT team looked forward to the on-orbit observatory operations, first contacts, and the commissioning phase of the observatory, that is also described on this paper

LE FORT I OSTEOTOMY AS A SURGICAL APPROACH TO REMOVE A JUVENILE OSSIFYING FIBROMA IN THE MAXILLARY SINUS: PEDIATRIC CASE REPORT

Ossifying fibroma (OF) is a well-defined benign neoplasm formed by different fibrocellular tissue and mineralized material. The OF clinical presentation is commonly an asymptomatic slow-growing swelling, mainly affecting the posterior mandibular region. Radiographically, this condition is characterized as a well-defined lesion with radiopaque and radiolucent areas. Histopathology shows dense cellular fibrous stroma and characteristic spheroidal calcifications called psammoma bodies. Regarding pediatric patients, the Juvenile Ossifying Fibroma (JOF) is an uncommon benign fibro‑osseous lesion with fast growth that impacts the facial skeleton, as it has a high-frequency potential. It occurs in early life, and approximately 79% are diagnosed before the age of 15 years. It affects both genders equally, and the maxilla is more involved compared to the mandible, there are cases also discovered in the orbit and skull. Surgical intervention to remove the tumor is the treatment of choice. The article presents a case of a pediatric patient who had the diagnosis of Juvenile Ossifying Fibroma and was submitted to surgical removal. The Le-Fort I Osteotomy approach proved to be safe, as it allows direct access to the base of the skull, allows good visualization and tumor exposure, and also allows easy tumor manipulation and curettage, enabling the preservation of facial aesthetics.Ossifying fibroma (OF) is a well-defined benign neoplasm formed by different fibrocellular tissue and mineralized material.

Bovine Mastitis Caused by Multidrug-Resistant Nocardia farcinica

Background: Mastitis caused by Nocardia is characterized by pyogranulomatous inflammation related to inadequate hygiene conditions and is difficult to treat. Prompted by the absence of documentation of Nocardia farcinica associated to bovine mastitis in the Northeast region of Brazil, this is the first report to describe bovine mastitis caused by multidrug-resistant N. farcinica. Case: Four milk samples (one from each teat) obtained from a 3-year-old Jersey cow raised on a property located in the metropolitan region of Recife, Pernambuco state, Brazil, were submitted to the Laboratory of Infectious-Contagious Diseases of the Veterinary Hospital at Universidade Federal Rural de Pernambuco. At the laboratory, samples were cultured in base agar enriched with 7% sheep blood (blood agar) in a microbiological incubator at 37°C under aerobic conditions for 72 h. After only 48 h, however, pure bacterial colony growth was observed in all samples. Macroscopic analysis revealed small colonies, with an irregular shape, dry aspect, and greyish in color. Gram-positive rods forming filaments and/or ramifications were observed using a Gram staining method. Nocardia spp. were identified according to morphotinctorial characteristics. Susceptibility testing using the disc-diffusion method in agar (antibiogram) was performed using the following antibiotics: penicillin (10 IU), tetracycline (30 µg), amoxicillin (10 µg), gentamicin (10 µg), cephalexin (30 µg), erythromycin (15 µg), cephalothin (30 µg) and ampicillin (30 µg). However, the organism exhibited resistance to all drugs; as such, a new milk sample was obtained at the same location the initial samples were collected. Samples (approximately 5 mL) were collected aseptically and separately from all four teats in sterile bottles, during which the presence of granular material was noted. Bacterial culture was performed as previously described and, after 48 h, colony growth with the same characteristics as the first isolation were observed, and with same morphotinctorial characteristics in the Gram stain. A resistance profile was observed for 14 of the antimicrobial drugs tested; sensitivity was verified only for ciprofloxacin and amoxicillin with clavulanic acid. One bacterial colony was selected and sent to the Center of Strategic Technology of Northeast (CETENE-PE) for species identification using a matrix-associated laser desorption ionization-time of flight (MALDI-TOF/MS) technique, which confirmed the species to be N. farcinica. Molecular characterization of 16s ribosomal DNA was performed using polymerase chain reaction with universal prokaryotic primers 516F-13R. Subsequently, the amplified product was subjected to sequencing, and the result was analyzed for quality using Phred base calling software; bases with a Phred value > 20 were kept. The sequence was evaluated using GenBank, in which the isolate exhibited 99% similarity to N. farcinica. Discussion: Clinical findings and animal history associated with microbiological culture and bacterial identification using the MALDI-TOF technique, as well as DNA sequencing, confirmed the case of clinical mastitis to be caused by N. farcinica. These bacteria are considered saprophytes, and their occurrence is associated with deficiencies in hygienic-sanitary management, such as not using pre- and post-dipping, which may favor mammary gland infection. Treatment of N. farcinica mastitis is effective only when properly performed, with agent identification and antibiotic sensitivity tests in vitro associated with the adoption of hygienic-sanitary measures. This is the first description of bovine mastitis caused by N. farcinica in the northeast of Brazil. Multidrug resistance should raise awareness of producers searching for laboratory aids in agent identification as well as antibiotic sensitivity tests, and to develop a proper therapeutic protocol based on results obtained in laboratory examinations

PHYSIOLOGICAL PERFORMANCE OF SEEDS OF Phaseolus vulgaris L. AS A FUNCTION OF ZINC AND PHYSIOLOGICAL MATURITY

The objective of this study was to study the physiological quality of bean treated with levels of zinc during the physiological maturation stage. The work was carried out at Fazenda Ponte da Braúna and at the Seed Analysis Laboratory of the Center for Agricultural Sciences and Engineering at the Federal University of Espírito Santo. Bean seeds of the cultivar Peanut were treated with Zn at concentrations of 0; 2.5; 5.0; 7.5 and 10 g kg-1 of seeds and sown in the field. The variables analyzed were seed moisture, 1000-seed weight, length, width and thickness of pods and seeds, germination, germination speed index, shoot length, root length, shoot and root dry matter. The experimental design used was completely randomized, in the factorial 5 x 7 (zinc doses x maturation periods), with four replications of 25 seeds. The seeds of the bean cultivar Amendoim treated with zinc at 10 g kg-1 seeds showed the highest values of pod length, thickness, and width. The seeds of the bean cultivar Amendoim showed the highest germination means and GSI after 35 days from anthesis. The treatment of seeds of the bean cultivar Amendoim with zinc does not influence the seedling characteristics. Seed treatment with zinc does not interfere with the seed maturation time of the bean cultivar Amendoim.  The physiological maturation of seeds of the bean cultivar Amendoim occurs after 42 days from anthesis. The seed water content of the bean cultivar Amendoim at the stage of physiological maturation is 19

Relationship between the vertical countermovement jump and the simulated performance of the initial 15 meters of crawl swimming performed by adolescent athletes

Background: The start in swimming occurs via a jump that propels the swimmer into the pool. The relationship of the power generated by the start jump to first 15-m performance in swimming events is not yet known. Objective: Verify the correlation of the countermovement vertical jump (CMJ) with the simulated start performance of the crawl swimming. Materials and Methods: The present research was observational pilot study. The sample consisted of 12 Brazilian swimmers aged between 12 and 16 years (male). The CMJ was analyzed by a specific Platform for Jump Testing. Afterward, the athletes were directed to an Olympic swimming pool and positioned themselves in the starting block. Then, at the sound signal (whistle), they swam the first 15 meters of the pool in crawl style at the highest possible speed to simulate the start of the competition of swimming. Results: Thus, the study showed a negative correlation of the CMJ with the simulated start of 15 meters in the crawl style (r =-0.816; p=0.001). The analyses indicated that the CMJ contributes 66% (F (1.10) = 19.92; p=0.001) for the performance of 15 meters during the simulated start of the crawl stroke. It was shown that for every 1 cm increase in CMJ height, there was an improvement of 0.0885 milliseconds in swimming performance. Conclusion: CMJ is associated with the variation of the sprint time during the simulated start of a swimming test in the crawl swimming style
