Overview of The Methodological Characteristics of Soybean Research in Brazil
Authors: Ceolin Jean Francisco Ravanello , Pantoja Maria Júlia 
Published: December 2023

Objective: Analyze the methodological characteristics of research on soy in master's programs in agribusiness in Brazil.

Theoretical framework: Due to the economic-social importance that the soybean complex has for Brazil, studies carried out by researchers at postgraduate level in Agribusiness in the country are essential to subsidize improvements for the sector.

Methods: A bibliographical survey of dissertations from stricto sensu Postgraduate Programs in Agribusiness - academic modality was carried out.

Results and discussion: The results showed that in 49% of the dissertations, the research methods are not described, nor are the techniques used in data collection and analysis. Among the dissertations that explained the methodological procedures, more than half (57%) portrayed their research as exploratory. The qualitative approach was characterized by (48%) of the authors, (26%) of them defining the studies as quali-quanti. The interview technique was described in 48% of the works analyzed. More than one type of instrument was used in 22% of cases and the questionnaire presented the lowest proportion (13%). Most of the research carried out on soy focuses on the private sector (74%).

Implications of the research: Some characteristics and specificities should be analyzed in future studies, such as: verifying the types of work concentrated in specific areas, agronomy and economics, which appeared as priority in this research; and, analyze the veracity of the information presented by the authors regarding the approach to the data, as well as the data collection techniques, as inaccuracies were found in the reports of the analyzed works.

Purpose: The aim of this study was to investigate how soil bacterial abundance relates to soil C, N and P contents along land use change gradient in the Cerrado landscape.

Method/design/approach: Land use categories were classified according to the succession stage of natural vegetation and agricultural activity. Soil physicochemical analyzes and plate counts of cellulolytic, amylolytic, free-living diazotrophic, phosphate solubilizing and actinobacteria were carried out. Linear regression analysis was used to investigate the interaction between the abundance of bacterial cultivable groups and soil C, N and P contents. Redundancy analysis (RDA) was used to determine the influence of environmental variables. Land use change affected how bacterial cultivable abundance interacts to soil C, N and P dynamics.

Results and conclusion: The regression analysis revealed 27 significant interactions between bacterial cultivable abundance (BCA) and soil C, N and P contents. In general, the increase of BCA is related to higher soil C, N and P rates. The influence of BCA in soil nutrient cycling seems to be more expressive in stressful environments such as intermediate succession area and agricultural lands. Nitrogen was the most affected nutrient and actinobacteria are the microbial group that can most enhance soil fertility. RDA showed that K, Mg and Ca contents were the main environmental factors acting on bacterial abundance.

Research implications: Conservation of natural resources and maintenance of biodiversity.

Originality/value: Soil bacterial functional groups and actinobacteria are directly involved in biogeochemical cycling being key factors for ecosystem conservation.
Experimental Investigation of Control Effects of Flapping Jets on Supersonic Cavity Flow
Authors: Oka Yoshinori , Ozawa Yuta , Handa Taro , Nonomura Taku 
Published: December 2023

The present study investigated the effects of active flow control by high-frequency flapping jets on a supersonic cavity flow. The discharging position was varied at the leading edge, the bottom wall upstream side, the bottom-wall downstream side, and the trailing edge. The flapping jets’ frequencies were varied at 0 (non-flapping case), 15, and 22 kHz, respectively. Discharging non-flapping jets at the leading edge and the bottom wall upstream side remarkably enhanced pressure fluctuations and density gradients. The reverse flow near the bottom wall and the amplitude of the recirculation inside the cavity were enhanced when non-flapping jets were discharged at the leading edge. Discharging non-flapping jets at the bottom wall downstream side reduced the pressure fluctuations of the frequency lower than 8 kHz. Discharging flapping jets changed flowfields, although the flow control effects of discharging positions were dominant. The flapping-jet discharging at the leading edge reduced the size of the primary recirculation. Discharging flapping jets at the bottom wall downstream side showed further suppression effects on fluctuations than the non-flapping-jet discharging case. There were no significant effects on the pressure fluctuations when the jets were discharged at the trailing edge.
Experimental Investigations of Failure Behavior for Aerogel-Cored Stitched Sandwich Composites Under Vibration Conditions
Authors: Tian Zhiqiang , Zhang Peiwei , Fei Qingguo 
Published: December 2023

Aerogel-cored stitched sandwich composites (ACSSCs), which possess numerous desirable properties, are anticipated to become the preferred choice for next-generation integrated thermal protection systems (ITPSs) in high-speed vehicles. Despite the reinforcement provided by stitching, the ACSSC structures on vehicles’ outer surfaces remain vulnerable to damage resulting from the excessively high deformation and vibration that occur during high-speed flight. Accordingly, experimental tests were conducted to investigate the failure characteristics of ACSSCs under bending vibration conditions. The tests demonstrated that the ACSSC structures were prone to fatigue failure caused by vibration, which resulted in significant shear damage in the aerogel core. Furthermore, the study introduced a new method for indirectly characterizing the fatigue life of shear damage in the core. Finite element analysis was undertaken to elucidate the cause of the cracking near the bottom layer of the core. The results indicated that the crack location of the aerogel core was littered with the high stiffness and deformation of internal stitches.
Interacting Linear Modes in the Turbulent Flow of an Industrial Swirled Combustor

Published: December 2023

Swirled flows often feature global modes that become manifest as skew-symmetric helical vortices, also known as precessing vortex cores, which dominate the flow dynamics. This study uses linear stability analysis (LSA) and bispectral mode decomposition (BMD) to elucidate the interactions of such modes in the turbulent, nonreacting, swirled flow of an industrial, three-passage, aeroengine fuel injector obtained via large-eddy simulation. A discrete Fourier transform in time retrieves the modes as narrow-banded, evenly spaced peaks in the spectral amplitude of the turbulent signal, where the second mode is dominant. Similar arrangements are known to appear as a consequence of a saturated global mode, which amplifies its higher harmonic frequencies due to nonlinear effects. We show that each mode appears in the spectrum of LSA eigenvalues, indicating that the subdominant peaks are caused not only due to nonlinear interactions but that they have an underlying linear mechanism. A structural sensitivity analysis based on the adjoint LSA shows that the observed helical modes originate close to the exit plane of the fuel injector. Finally, the BMD reveals significant nonlinear interaction between the individual modes. It is hypothesized that this interaction amplifies the modes, which are linearly stable, leading to the strong dynamics in the flow.
WHAT CAN FIGHTING TELL US ABOUT JOURNALISTIC IDENTITIES?
Authors: Pereira Fábio Henrique 
Published: December 2023

ABSTRACT – In this essay we argue that journalists’ engagements, their fights, reveal, indeed, the dynamics of how their professional identities are constructed. By engaging in a struggle, the journalist seeks to state something about himself, for himself (and his profession group) and for the others (actors that participate in this public combat). The journalism fights reveal the way the professional group (or part of it) tries to manage its relationship with rival actors at the same time it expresses a public discourse about its practice, its identity. The journalism fights reveal the temporary or permanent alliance journalists establish within the professional group, as so with external actors who share the same interests. Fighting is also participating in the construction of a social problem, by converting some issues/situations specific to the professional group to a subject that interest the whole society.
RESUMO – Neste ensaio, argumentamos que o engajamento dos jornalistas, suas lutas, revelam as dinâmicas de construção das identidades profissionais. O jornalista, quando se engaja em um combate, tem a intenção de dizer algo sobre si, para si (para o grupo profissional) e para os outros (atores que participam do combate público). Os combates do jornalismo revelam a forma como o grupo profissional (ou parte dele) busca gerir as relações com atores concorrentes ao mesmo tempo em que exprime um discurso público sobre sua prática, sua identidade. Os combates do jornalismo também revelam as alianças, temporárias ou permanentes, que os jornalistas estabelecem no interior do grupo, mas também com atores externos, que partilham dos mesmos interesses. Combater é também participar da construção de um problema público, por meio da conversão de certas questões/situações específicas ao grupo profissionais em um tema de interesse da sociedade.RESUMEN – En este ensayo, sostenemos que el compromiso de los periodistas, sus luchas, revelan la dinámica de construcción de sus identidades profesionales. Cuando el periodista entra en combate, él pretende decir algo sobre sí mismo, para sí mismo (para el grupo profesional) y para los demás (actores que participan en el combate público). Las luchas del periodismo revelan la forma en que el grupo profesional (o parte de él) procura gestionar las relaciones con sus competidores mientras expresa un discurso público sobre su práctica y identidad. Los combates del periodismo también revelan las alianzas, temporales o permanentes, que los periodistas establecen dentro del grupo, pero también con actores externos, que comparten los mismos intereses. Combatir es también participar en la construcción de un problema público, a través de la conversión de determinadas cuestiones/situaciones propias del colectivo profesional en un tema de interés para la sociedad.

Published: December 2023

Objectives:
The position of the head to the neck is affected by various factors, including respiratory tract features, temporomandibular joint disorders, type of occlusion, and physical aspects. In addition, malocclusion can negatively affect the head-neck position. The present study aimed to evaluate changes in natural head position following treatment of Class II malocclusions with Farmand II functional appliance.

Material and Methods:
The present study was implemented as a historical cohort with the before and after design. Pre- and post-treatment lateral cephalometric radiographs of 33 skeletal Class II patients treated with the Farmand II functional appliance were included in the present study. The cephalometric analysis was done by tracing the related lines and landmarks. Facial angles and angles determining the natural head and neck position including craniohorizontal, craniocervical, craniovertical (CCV), and cervical curvature (CCI) were measured. Collected data were entered in Statistical Package for the Social Sciences (SPSS)-version 17 software. Paired t-test was used to evaluate the changes in cephalometric indices before and after treatment. P < 0.05 was defined to be statistically significant for all the tests.

Results:
The results of the present study, showed a significant reduction in the mean values of A point, nasion, B point (ANB) angle and angle of convexity following treatment (P < 0.001); also, Sella-nasion/Odontoid process tangent (SN/OPT) angle showed a substantial decrease in treated patients (P = 0.033), which is indicative of head flexion following treatment. Moreover, the decrease in the mean values of the craniocervical angles, including True vertical line (NL/VER) and Sella-nasion/true vertical line (SN/VER), suggests downward bending of the head in patients treated with this appliance (P-values of 0.029 and 0.012, respectively). The odontoid process tangent/cervical vertebra tangent (OPT/CVT) angle showed an insignificant increase (P = 0.260).

Conclusion:
The present study showed that patients treated with the Farmand II functional appliance tend to flex their heads and maintain their cervical vertebra in a more upright and straight position.
3D wrist imaging – Is it time for superman to retire?
Authors: Mørup Svea Deppe , Mussmann Bo , Pedersen Malene Roland Vils , Rasumssen Lykke Moseholm , Gaarde Katrine , Jensen Janni 
Published: December 2023

Objectives:
Computed tomography (CT) of the wrist may be challenged, due to patients’ inability to extend the arm for a “Superman pose” resulting in increased radiation dose due to scatter. Alternative positions and less dose administering modalities such as 3D Cone-beam CT (CBCT) and single-shot CT could be considered. This phantom study aimed to estimate scatter radiation dose in different phantom positions using helical and single-shot CT and 3D CBCT.

Material and Methods:
Wireless electronic dosimeters attached to the head and chest of an anthropomorphic phantom in various clinically relevant positions were used to measure scatter radiation. In helical CT, the following positions were used: Superman pose, semi-superman pose, wrist on the abdomen, and single-shot CT with the patient sitting in front of and behind the gantry. In 3D CBCT, the phantom was in a supine position with the arm extended laterally.

Results:
Helical CT using the Superman pose resulted in a total scattered radiation dose of 64.8 µGy. The highest total dose (269.7 µGy) was obtained with the wrist positioned on the abdomen while the lowest total dose was achieved in single-shot CT with the phantom sitting behind the gantry with the forearm placed inside the gantry (3.2 µGy). The total dose in 3D CBCT was 171.1 µGy.

Conclusion:
The commonly used semi-superman and wrist-on-abdomen positions in CT administer the highest scattered doses and should be avoided when either single-shot CT or 3D CBCT is available. Radiographers should carefully consider alternatives when a patient referred for wrist CT cannot comply with the Superman position.

Background
. We investigated the demographic, aetiological and clinical characteristics of patients who presented to the emergency department and had severe hyponatraemia.

Methods
. We retrospectively evaluated 1171 patients who presented to the emergency department and were diagnosed with severe hyponatraemia.

Results
. Over half the patients studied were women (53.5%). The mean age of women was higher (p<0.0001). The most common complaint was dyspnoea (16.8%) and 42.5% of the patients had an oral intake disorder. In addition, 22.3% of the patients were on loop diuretics. About 76.3% of patients were conscious, and the mean sodium level of these patients was higher than the mean sodium level of those who responded to verbal and painful stimuli (p<0.001). Severe isolated hyponatraemia was observed in 61.8% of the patients. The mortality rate was 12.8%. There was no difference between the mean sodium levels of the deceased and discharged patients (p=1.0). The mortality rate was higher in patients who had a history of cirrhosis and cancer, but was lower in patients with a history of coronary artery disease (p=0.0002, p<0.0001 and p=0.04, respectively).

Conclusion
. Severe hyponatraemia was more prevalent in women, serum sodium levels were higher in conscious patients, and the mortality rate was higher in patients who had a history of cirrhosis and cancer. We found that the mean serum sodium levels did not help in distinguishing between the deceased and discharged patients.

The research objective was to determine the results of the camat's assignment in fostering village governance in Lubuk Batu Jaya Subdistrict, Indragiri Hulu Regency. This is to find out the obstacles to the task of the sub-district head in fostering village governance in Lubuk Batu Jaya Subdistrict, Indragiri Hulu Regency. This type of descriptive research uses a quantitative approach with a population of 23 people, community leaders, village heads and camat office employees. Data collection was carried out by means of interviews, questionnaires, documentation and observation, all data collected were grouped by type and analyzed descriptively and conclusions could be drawn from the research results. Based on the results of the study, it was found that the evaluation of the sub-district head's duties in conducting Village Government Development in Lubuk Batu Jaya District, Indragiri Hulu Regency was in the quite good category, due to the five research indicators, namely providing guidance, giving direction, providing education and training, giving instructions and literature or the manual has been implemented. The inhibiting factor for the guidance carried out by the sub-district head to the village government is that the guidance carried out by the sub-district head has not been carried out routinely, the direction is given to the sub-district head only if the village apparatus experiences problems in the work process, and the sub-district head does not provide education and training every month, the sub-district head only provides guidance if he receives a report. village government task constraints.

В статье приведены результаты экспериментов по воспроизведению процесса прерывистого скольжения по готовому разрыву «stick-slip» в упруговязкопластичной модели. Известны многочисленные примеры экспериментального воспроизведения этого процесса для поиска признаков подготовки импульсного смещения по разрыву, которые могли бы интерпретироваться как предвестники готовящегося землетрясения в природе. В этих экспериментах в качестве моделей использовались горные породы и другие материалы, обладающие высокой степенью упругости и склонные к хрупкому разрушению. Представленные в настоящей статье результаты получены на упруговязкопластичных моделях. Использование таких моделей в описываемых экспериментах авторам не известны. Модельными материалами служили водная паста монтмориллонитовой глины и влажный речной песок. В результате проведенных экспериментов установлены характерные стадии деформирования околоразломной зоны, одна из которых соответствует медленному скольжению материала с апериодическими флуктуациями смещения. На основе анализа цифровых изображений определены как области избытка, так и области дефицита смещения по простиранию модельного разлома.
This paper presents the results of experiments to reproduce the process of stick-slip along a pre-existing stick-slip discontinuity in an elastoviscoplastic model. There are numerous examples of this process being reproduced experimentally to look for signs of the preparation of pulsed displacement along a fault, which could be interpreted as a harbinger of an impending earthquake in nature. In these experiments, rocks and other materials with high elasticity and susceptibility to brittle fracture were used as models. The results presented in this article were obtained using elastoviscoplastic models. The authors are not aware of the use of such models in the experiments described. The model materials were an aqueous paste of montmorillonite clay and wet river sand. As a result of the experiments, characteristic stages of deformation of the near fault zone were identified, one of which corresponds to slow sliding of the material with aperiodic displacement fluctuations. Digital image analysis was used to identify areas of both excess and deficient displacement along the strike of the model fault.
