Published: May 2019

Purpose of Study: The article is devoted to the study of the organization of educational activities of volunteers as a social and educational project. It is established that the strategic goal of the new generation of Federal-state educational standards is the formation of graduates ' competences. A framework of competence approach helps to gradually transfer the student from learning activities to his future professional activities. In this article, the authors identify the activities of volunteers as one of the ways to adapt students to real working conditions. The article reveals the essence of volunteer activity, which allows to acquire new and improve existing competencies as a social and educational project. In the Nizhny Novgorod State Pedagogical University named after KozmaMinin, the development of volunteer activities proceeds through the work of The center "territory of opportunities", implemented within the framework of the project "Social and educational environment", in which a sufficient number of stakeholders are involved, providing students with the opportunity for further employment. The article also highlights the activities carried out by the Center, for which volunteer students are offered a lot of special courses (social design, robotics, ZD-modeling). On the basis of the revealed facts, the positive effect of volunteer activity for all participants of this process is established.
Methodology: The paper presents an analysis of employed student volunteers. As practice shows, students engaged in volunteer activities, quickly enough to get a job in the profession, unlike students who do not have the experience of volunteering. 49% of volunteers work on a permanent or partial basis, while students without volunteer experience employ only one in three students (33%) [Pavlov, Kindaev, Vinnikova, & Kuznetsova, (2016)]. In order to identify the positive impact of this activity on the development of students as professionals, we have shown the activities Of the center "territory of opportunities", which operates in the Nizhny Novgorod state pedagogical University named after KozmaMinin.
Results: Results showed ha students engaged in volunteer activities are more satisfied with their leisure time compared to ordinary students. In addition, the study showed that those students who have devoted their time to participate in volunteer activities are employed much faster than students who have not engaged in volunteering.
Implications/Applications: The higher education institutions should make every effort to improve the conditions in which volunteer activities are carried out and offer ample opportunities for the development of the student's personality because students can easily employ both in the learning process and after graduating from high school.

Published: May 2019

Case:
A 32-year-old right-handed surgeon presented with a history of intermittent pain at the right medial epicondyle, a mild Tinel's sign, and dysesthesia in the ulnar nerve distribution. Dynamic ultrasound demonstrated a hypertrophic anconeus epitrochlearis bilaterally, and chronic irritation of the ulnar nerve. Anterior release with myectomy of the accessory muscle was performed. No compressive symptoms were present at 1-year follow-up.

Conclusions:
The anconeus epitrochlearis is an often-underappreciated cause of ulnar nerve compression that can lead to significant functional impairment. Dynamic ultrasound is an excellent diagnostic modality, and anterior release with myectomy provides durable relief with minimal downtime.

Abstract
Background: How to promote true recovery from poststroke upper limb motor impairment has remained an urgent public health problem. Acupuncture has the potential to facilitate poststroke recovery. Abdominal acupuncture, based on the recently discovered acupoint system on the anterior abdominal wall, appears attractive because it induces less pain, and allows concurrent limb rehabilitative training during treatment. However, its clinical efficacy has not been systematically demonstrated, and its neurophysiological mechanism has remained obscure.

Methods: First-onset stroke survivors (0.5-3 months post-stroke) will be randomly divided into 3 groups (N=22 in each), respectively receiving (1) abdominal acupuncture, (2) abdominal acupuncture with sham needles, and (3) no acupuncture. All subjects will concurrently receive basic treatment, including upper limb rehabilitative training and measures for secondary stroke prevention. Clinical scores reflective of motor functions and impairment (Wolf motor function test, Fugl-Meyer assessment, Brunnstrom staging), evaluation of daily life ability, surface electromyography, and motor-imagery functional magnetic resonance imaging will be collected as outcome measures before and after intervention. Upper-limb muscle synergies will be identified from the collected surface electromyography.

Discussion: The study will use abdominal acupuncture to improve recovery from motor dysfunction of the upper limb after stroke, to observe the effects of abdominal acupuncture on post-stroke upper limb motor functions, and to analyze the relationship between changes in upper-limb functions and measurements from both multi-muscle surface electromyographic data and brain activations during motor imagery from functional magnetic resonance imaging, so as to explore possible mechanisms of neuroplasticity associated with abdominal acupuncture.

Trial registration: This trial was registered with the ClinicalTrials.gov (ID: NCT03712085) on 7th July 2018, and last updated on 16th Oct 2018.

Interdisciplinary efforts in high‐throughput field phenotyping
Linking proximal and remote field phenotyping
Cyberinfrastructure for high‐throughput field phenotyping
Plant breeding and agronomy are labor‐intensive sciences, and the success of these disciplines is critical to meet planetary challenges of food and water security for the world's growing population. Recent gains in sensor technology, remote sensing, robotics and autonomy, big data analytics, and genomics are being adopted by agricultural scientists for high‐throughput phenotyping, precision agriculture, and crop‐scouting platforms. These technological gains are ushering in an era of digital agriculture that should greatly enhance the capacity of plant breeders and agronomists. This report encompasses the priorities and recommendations that emerged from two USDA National Institute of Food and Agriculture (NIFA)‐funded Big Data Driven Agriculture workshops held on 26–27 Feb. 2018 in Arlington, VA. The objectives of the workshops were to bring together diverse subject‐matter experts in the represented disciplines of plant breeding, machine learning, remote sensing, and big data infrastructure and analytics to (i) explore how large and comprehensive datasets in plant breeding, genomics, remote sensing, and analytics will benefit agriculture; (ii) discuss strategies for creating a successful field phenotyping campaign and to determine protocols for the collection and analysis of agricultural big data; (iii) consider how to best engage the broader community of public and private plant breeders and agronomists to determine additional challenges, make wider use of the data, and ensure application of standardized methods to other datasets; and (iv) generate a report describing cross‐cutting short‐ and long‐term funding needs for continued success in this domain.

Core Ideas
Bahiagrass–rhizoma peanut mixtures resulted in similar whole soil C stocks as N‐fertilized bahiagrass monocultures.
Bahiagrass–rhizoma peanut mixtures had greater total and particulate organic matter C than rhizoma peanut monocultures.
Particulate organic matter C/N ratio of rhizoma peanut and N‐fertilized bahiagrass monocultures were lower than C/N ratio in bahiagrass–rhizoma peanut mixtures.
The use of δ13C to verify changes in the soil organic matter caused by the plant component was a better predictor than the use of δ15N.
Soil particulate organic matter (POM) represents a labile soil organic matter (SOM) fraction and is an important source of nutrients for soil microorganisms and plants. This study assessed C and N stocks in POM and soil mineral‐associated fractions for forage mixtures of rhizoma peanut (RP; Arachis glabrata Benth.) and bahiagrass (Paspalum notatum Flüggé) in contrast with their monocultures. Treatments included two bahiagrass entries receiving 90 kg N ha–1 harvest–1, two RP entries, and the four bahiagrass–RP combinations. Samples were collected from the 0‐ to 15‐cm soil depth in July 2015 and in September 2016, after seven harvests. Soil samples were fractionated into POM and mineral‐associated organic matter (MAOM) by dispersion with sodium hexametaphosphate and sieving (53 μm). Samples were analyzed for δ13C, δ15N, and total C and N. Groups of bahiagrass, bahiagrass–RP, and RP were contrasted. There were no differences in N stocks among forage treatments. Bahiagrass–RP mixtures had greater soil POM‐C stock (5.1 Mg C ha–1) than RP monocultures (4.0 Mg C ha–1). Soil POM C/N ratio was lower for bahiagrass (18.2) and RP monocultures (16.2) than bahiagrass–RP (20.6). Bahiagrass–RP and bahiagrass had similar soil δ13C and were less depleted than RP (–23‰ vs. –26‰ and –26‰ vs. –28‰, for POM and MAOM, respectively). Soil POM‐C stock under forage mixtures was not different from N‐fertilized bahiagrass, and it was greater than RP. Hence, mixing RP and bahiagrass can be an option to increase POM‐C without the need of N fertilizer.

Core Ideas
For preferential flow modeling, different macropore types must be considered.
A method was developed for separating biopores and cracks in 3D images from XRCT.
The method enabled a more objective determination of structuring element sizes.
The voxel‐based approach was found useful for quantification of macropore types.
In structured soils, earthworm burrows, root channels, shrinkage cracks, and interaggregate spaces form complex macropore networks. Depending on the type and morphological properties, each macropore surface type is coated with specific organo‐mineral compounds, differently affecting sorption and mass exchange during preferential flow and turnover processes. For a quantitative, macropore type–specific analysis using X‐ray computed tomography (XRCT) with subsequent three‐dimensional (3D) image analysis, a discrimination of biopores from cracks and interaggregate spaces is necessary. We developed a method that allows separating biopores from other larger macropores in 3D images from XRCT of intact soil cores. An image‐processing workflow using the MAVI (Modular Algorithms for Volume Images) software framework ToolIP (Tool for Image Processing) was created to handle XRCT 3D images. Masking steps enabled to retain the surface roughness in the resulting two images of separated biopores and cracks. As a key point, the sizes of the structuring elements used in the spherical opening and dilation were objectively determined. For this purpose, maximum differences in the pore shapes between the 3D images of cylindrical biopores vs. more flat cracks and unregularly interaggregate spaces were focused. At the given resolution of 231‐μm voxel edge length, an optimum size of 2.5 voxels was found for both processing steps. The voxel‐based approach is applicable to XRCT 3D images of different spatial resolution and appears useful for the quantification of physicochemical surface properties of different macropore types for soil volumes, enabling a more precise description of preferential flow and transport.

The short-term streamflow forecast is an important parameter in studies related to energy generation and the prediction of possible floods. Flowing through three Brazilian states, the Paraíba do Sul river is responsible for the supply and energy generation in several municipalities. Machine learning techniques have been studied with the aim of improving these predictions through the use of hydrological and hydrometeorological parameters. Furthermore, the predictive performance of the machine learning techniques are directly related to the quality of the training base and, moreover, to the set of hyperparameters used. The present study explores the combination of the Gradient Boosting technique coupled with a Genetic Algorithm to found the best set of hyperparameter to maximize the predicting performance of the Paraíba do Sul river streamflow.

A hidroxiapatita cerâmica foi sintetizada pelo método de co-precipitação úmida e digestão lenta, tendo como reagentes precursores o ácido ortofosfórico e o hidróxido de cálcio. Desta forma, a síntese da hidroxiapatita deficiente é iniciada. O artefato de síntese baseado em haste metálica é montado em um Becker com solução de hidróxido de cálcio com gotejamento controlado de ácido fosfórico na taxa de 5 gotas por minuto em fluxo constante em um total de 5 horas em um sistema montado sobre a placa de aquecimento com agitação magnética. A massa obtida foi seca (estufa a 500C) por 3 dias, triturada (gral de ágata) e peneirada (tamizes controladas). Os pós foram prensados por prensagem uniaxial usando uma força de 500Kg em um molde-matriz de aço com um diâmetro de 15mm e uma altura de 3-4mm. Em seguida, as pastilhas obtidas foram calcinados a 1100ºC em forno com rampa específica controlada. As pastilhas foram caracterizadas por DRX, FTIR, Raman e AFM, além da análise do dilatômetro e histeresímetro. Após essa etapa, as nanopartículas de prata (AgNPs) foram sintetizadas na superfície e analisadas por MEV e EDS. Foi possível obter o modelamento das etapas cruciais. Os resultados mostraram que foi possível obter a matriz de hidroxiapatita comprovada pela caracterização físico-química e recobrí-la com nanopartículas de prata (AgNPs) em estrutura semelhante ao design final necessário para aplicação de defeitos ósseos críticos.

El suicidio se considera un problema de salud pública que ha aumentado exponencialmente, por lo que identificar población en riesgo suicida, así como factores asociados es esencial para su prevención en la población adolescente. Este estudio, analizó en qué medida la autoestima, la desesperanza y factores sociodemográficos, inciden en la presencia de riesgo suicida en adolescentes de educación media superior; para ello, se trabajó con un total de 74 participantes hombres y mujeres con un rango de edad de 15 a 18 años, de una población no clínica clasificados en dos grupos: con y sin riesgo suicida, en igual número y características de edad y sexo. Se aplicó la escala de riesgo Suicida de Plutchik (1989; 1998), la escala de Autoestima de González-Arratia (2011) y la escala de Desesperanza de Córdoba, Rosales y Eguiluz (2005). Los resultados indicaron la existencia de una relación positiva significativa entre las variables de riesgo suicida y desesperanza e inversa con autoestima. Respecto al tipo de familia, los participantes de familia monoparental, puntuaron más alto tanto en riesgo suicida como en desesperanza. Del modelo de regresión logística binaria, se obtuvo que la variable que predice el riesgo suicida es la desesperanza, seguida de la autoestima. No se reportan diferencias entre hombres y mujeres en ninguna de las variables evaluadas. Se concluye que la desesperanza incrementa la probabilidad de riesgo suicida, por lo que su inclusión es esencial en futuros estudios empíricos, así como en modelos de prevención e intervención en adolescentes.

Published: May 2019

Trata-se de uma revisão narrativa sobre a importância da consulta do enfermeiro durante o pré-natal da gestante de baixo risco, utilizando a abordagem centrada na pessoa - gestante. O pré-natal é o acompanhamento da evolução da gestação que visa cuidar da saúde da mulher e do seu bebê até que o parto ocorra, também é o momento que a gestante vivencia diferentes sentimentos, por isso o estabelecimento de relação com a enfermagem se faz imprescindível. O pré-natal quando realizado com qualidade desempenha importante papel na redução da mortalidade materna e infantil. Informações sobre as diferentes vivências devem ser trocadas entre as mulheres e os profissionais de saúde. A consulta de enfermagem é uma atividade que irá proporcionar ao enfermeiro (a) condições para atuar de forma direta e independente com a paciente, caracterizando dessa forma sua autonomia. Segundo a Secretaria Municipal de Saúde do Rio de Janeiro, a abordagem centrada na pessoa – gestane deve ser uma ferramenta primordial na Estratégia de Saúde da Familia, pois propicia o vínculo, atendimento integral e fortalecimento da longitudinalidade do cuidado alem de ser uma tecnologia leve, utilizada pelo profissional que permite idenificar as últiplas vulnerabilidades, fazendo com que diminuam se as chances de complicações e mortalidade materna e infantil e uma boa qualidade do pré-natal. Espera-se que este estudo contribua para reflexão do enfermeiro, quanto a sua importância nesse contexto, visando uma assistência à gestante cada vez mais humanizada e científica.
