title: Analysis of main elements in locking plating design on a 2-part fracture of the surgical neck of the humerus using FEM and statistical analysis

description: ABSTRACT A large number of proximal humerus fractures are being treated with osteosynthesis. However, loss of reduction remains a serious problem and it can cause screw cutout at the humeral joint and reoperation. According to the interfragmentary strain theory, one should be aware of the balance between a flexible fixation, which stimulates callus formation, and an unstable fixation, leading to implant failure. The main elements that are implicated in this case include physiological loading conditions, support screws configuration, implant material and bone quality. The objective of this research was to detect the influence of the above elements to formulate a positive scene to reduce the risk of failure in the fracture. A factorial experimental design was used in combination with the use of the finite element method to give rise to data collection. The results suggested that implant material is the element with the most significant influence and it contributes to stabilizing the fracture fixation, following by the support configuration. The practice of including a medial support with calcar screws on different bone tissue qualities offers a more favorable rigidity than those who do not use them. This affirmation is supported by the results of recently published reports. In addition, the medial support reduces the strain in the bone-plate join. Although these results showed a too moderate evaluation per the use of an isotropic model, they are effective to know the biomechanical elements and their influence to describe a behavior trend and create a basis for future studies. In addition, the computing time decreased considerably.

title: Sensory evaluation and antioxidant capacity as quality parameters in the development of a banana, strawberry and juçara smoothie

description: Abstract In the present study a banana, strawberry and juçara smoothie was developed using an experimental mixture design. The juçara proportion was kept constant while the banana:strawberry ratio varied and the main responses were the sensory acceptability and the antioxidant capacity. From five formulations, only the one with the highest percentage of strawberry was rejected, most likely due to its lower sugar content and higher acidity. In general, panelists chose the sweeter formulations, which were those with a higher percentage of banana. Relating to the consistency, the best formulation was the one containing the same proportion of strawberry and banana pulp, which provided a better flow to the product. Additionally, this sample showed intermediate values of phenolic compounds and antioxidant capacity, as well as desirable physicochemical characteristics. In spite of being possible to obtain four formulations with good sensory acceptance, the one with equal amounts of banana and strawberry pulp is highlighted due to its antioxidant capacity and sensory characteristics, statistically corroborated by the desirability function.

title: Assessment of the product of nursing care in specialized hospitals

description: ABSTRACT Objective: To evaluate the product of care in units of specialized hospitals, identifying the items that most contributed to the score; to compare the product of care among hospitals, units, and shifts; to verify the association between demographic and professionals variables and the product of care. Method: Descriptive study, conducted in eight units of two specialized hospitals in the State of São Paulo. The evaluation of the product of care was performed by applying an instrument to 44 nurses. Results: "Multidisciplinary interaction and performance" obtained the lowest median in both hospitals, and the "Meeting assistance needs" and "Nursing care planning" were the better assessed ones. "Dimensioning of nursing staff" was the item that most contributed to the total score. There was a weak correlation between socio-demographic variables and score. Conclusion: The product of care, as found in both hospitals, was predominantly considered "good." The tool enabled the identification of critical aspects of the nursing work.

title: Spectral Efficiency Analysis in Massive MIMO using FBMC-OQAM Modulation

description: Abstract This article covers the potential of Filter Bank Multicarrier (FBMC) modulation as an alternative to be used in the future 5G wireless networks in which Massive Multiple-Input Multiple-Output (MIMO) will be deployed. The study compares orthogonal frequency division multiplexing (OFDM) with FBMC. The former is the multiplexing technique in 4G communications and the latter is one of the strongest candidates to replace OFDM in 5G networks. This comparison evaluates the spectral efficiency (SE) of a Massive MIMO (MM) system uplink under a single-cell environment. The diversity in MM permits a self-equalization of the channel, which the FBMC further benefits from, due to the confinement of the subcarrier in an assigned range. Due to the absence of the cyclic prefix, the FBMC has better SE than the OFDM for increasing signal-to-noise-ratio (SNR). One may find a scarce literature covering the FBMC in a large-scale multiuser MIMO scenario, which considers a large number of antennas at the base station (BS). Various scenarios are considered by varying the number of antennas, users and different cell radius. Moreover, the subcarrier modulations are simulated, and not considered Gaussian distributed, as in Shannon limit theory. In some cases, the FBMC allows doubling the cell radius for the same SE value of 3.8 bits/s/Hz/user. For a fixed cell radius of 750m and a SE of 3.5 bits/s/Hz/user, the OFDM requires three times more antennas than FBMC when both modulations are under the same conditions.

title: Performance of urea coated with polyurethane as a fertilizer for Phaseolus vulgaris L.

description: ABSTRACT Due to its great global importance, bean crop requires large-scale production, making necessary the usage of fertilizers. Among them, urea stands out as one of the most important. However, significant losses of nitrogen are constantly observed through leaching, volatilization and denitrification. In order to circumvent this problem, several research groups have studied the coating of fertilizers with polymers, since, through them, it is possible to control the release of nutrients as well as their availability in the soil. In this context, the present work aim son coating urea granules by means of a simple mixture of diphenylmethane diisocyanate and polyol polyether. Five types of coatings have been produced by varying the proportions of the reactants. All samples were characterized by infrared spectroscopy and scanning electron microscopy. In addition, in vivo assays were performed with Phaseolus vulgaris L.. Infrared spectra confirmed the polymerization by formation of the urethane bond. The micrographs showed coating with a thickness of less than 30 μm. Controlled release urea tests in water have shown that the polymer coatings delay release of the urea by approximately 50% over a period of 200 min. The results of the in vivo tests, in turn, showed that the use of urea with coatings in the 60:40 and 50:50 mass proportions (diphenylmethane diisocyanate/polyol polyether) increased the dry mass content in 52 and 22 %, respectively. In this way, it can be concluded that it is possible to coat nitrogen fertilizers simply with efficiency, allowing the release of nutrients into the soil and making it more sustainable.

title: Acid catalysts based on simple modification of chitosan for the esterification of oleic acid

description: ABSTRACT Chitosan is a linear polymer with excellent physicochemical properties and has been widely used in a variety of applications, including as a catalyst in various types of reactions. In this work, chitosanbased solids were synthesized in order to obtain an active and stable material to be used as a catalyst in esterification reactions. To this end, the chitosan was modified in order to potentiate its Bronsted acidity by acid hydrolysis using HCl or H2SO4 solutions and subsequent drying in a vacuum line. The synthesized materials were characterized and evaluated in the esterification reaction of oleic acid with methanol. Although modification of chitosan with dilute solutions of inorganic acids is a simple method for the preparation of heterogeneous acid catalyst, there is evidence that the materials are not stable against the leaching of the active species into the reaction medium under the conditions evaluated.

title: Spatial variability of coffee plant water consumption based on the SEBAL algorithm

description: ABSTRACT: Awareness of evapotranspiration (ET) and crop coefficient (Kc) is necessary for irrigation management in coffee crops. ET and Kc spatial variabilities are disregarded in traditional methods. Methods based on radiometric measurements have potential to obtain these spatialized variables. The Kc curve and spatial variability of actual evapotranspiration (ETa) were determined using images from Landsat 8 satellite. We used images of young and adult coffee plantations from OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors over a two-year period. Evapotranspiration was estimated using the Surface Energy Balance Algorithm for Land (SEBAL). Moreover, the reference evapotranspiration (ETo) was estimated through the Penman-Monteith method. We obtained the values for the evapotranspiration fraction (ETf), analogous to Kc, according to ET and ETo values. The study was conducted in Buritis, Minas Gerais State, Brazil, in areas cropped with Coffea arabica irrigated by central pivots. A comparative analysis was made using different statistical indices. Average ETa was 2.17 mm d−1 for young coffee plantations, , and the Kc mean value was 0.6. For adult coffee plantations, average ETa was 3.95 mm d−1, , and the K mean value was 0.85. The ET and K data obtained based on the SEBAL algorithm displayed similar values to studies that used traditional methods. This model has huge potential to estimate ET of different stages of coffee plantation for the region studied.
