Published: February 2023

A secagem é uma etapa determinante no processo de industrialização da madeira, exige muito critério e demanda o emprego de procedimentos técnico científicos. Muitas vezes, principalmente, micro e pequenas empresas que atuam no setor não adotam estes procedimentos, realizando o processo de secagem de forma inadequada. Neste contexto, o objetivo deste trabalho foi a produção de materiais digitais (informes técnicos e podcast) para divulgação científica da secagem da madeira. Os informes técnicos foram elaborados a partir da definição da temática, considerando demandas e anseios do setor. O podcast foi estruturado em episódios com entrevistas de professores e pesquisadores da área. As gravações ocorreram na Webconf da Universidade Federal de Pelotas (UFPel). Os áudios foram tratados e editados em programas livres e hospedados em plataformas livres. Foram produzidos dois informes técnicos e dezesseis episódios do podcast. Os materiais foram divulgados para empresas e associações do setor a partir de e-mails e disponibilizados no site do Laboratório de Secagem da Madeira (LASEMA) da UFPel. Materiais digitais como informes técnicos e podcasts, cada vez mais ganham importância, sendo promissoras ferramentas da divulgação científica no setor produtivo.
Aneurysmal subarachnoid haemorrhage in the pituitary fossa of a patient with acromegaly – a rare phenomenon
Authors: Fookeerah Prishila , McLean Mark 
Published: February 2023

Summary
The anatomy of the pituitary fossa is complex. The wall of the fossa can vary, resulting in inconsistencies in the nature and integrity of the sella barrier. Cerebrospinal fluid is generally confined to the subarachnoid space and does not circulate freely in the pituitary fossa. Spontaneous haemorrhage in the fossa typically occurs in the context of pre-existing intrasellar pathology such as a pituitary adenoma. Extravasation of blood into the subarachnoid space can rarely be observed following pituitary apoplexy. We describe the unique occurrence of subarachnoid haemorrhage in a largely empty pituitary fossa after the rupture of a cerebral aneurysm.

Learning points

Pituitary apoplexy and subarachnoid haemorrhage (SAH) are both high in the differential diagnosis of sudden onset severe headaches.

Haemorrhagic pituitary apoplexy may result in extravasation into the subarachnoid space, resulting in typical SAH symptoms and signs.

This is the first reported case of primary SAH resulting in blood pooling in an empty sella arising from previous surgical resection of a large macroadenoma.

Published: February 2023

In the study, band structure calculation in the points of high symmetry of the first Brillouin zone and alongside the lines that connect them has been derived by using CASTEP programs in which the pseudopotential method with the basis in the form of plane-waves is realized. The calculated value of the lattice parameters using GGA functional is well correlated with experimental data. According to the band diagram that was built for the Ag3AsS3 crystal using GGA method, band gap has an indirect type. The calculated value of the band gap is = 1.22 еV. The experimental value of the band gap obtained by Tauc’s method is = 2.01 еV, = 2.17 еV. Full and partial density of N(E) states for contributions of separate atoms has been calculated. As a result, the top of the valence band is formed by 3p-states of S atoms and the bottom of the conduction band is formed by 5s-states of Ag atoms and 3p-states of S atoms.

Authors: Lobo Joseph 
Published: February 2023

Background and Study Aim. Various published papers have already established the effectiveness of Kahoot! in bolstering students' academic performance through various games. However, there were few to no studies were conducted regarding its effectiveness in learning lecture-based concepts in Physical Education, most especially in the Higher Education setting. In this regard, this present study is aimed to assess the effectiveness of the said application via the Experimental approach.
Material and Methods. The respondents for the study are selected 2nd-year students from one section pursuing a Bachelor of Physical Education degree at City College of Angeles (Philippines). Participants were chosen via the Purposive Sampling Technique. 40 item test question covering the topics in Physical Education was formulated. The test question was used at the stage before the test and after the test. Furthermore, a questionnaire was used to assess students’ perception concerning the attribute of Kahoot! The entire experiment lasted for 5-weeks. The experiment was conducted two weeks after the start of the 2nd semester (academic year 2021-2022). Descriptive analyses (frequency, mean, and standard deviation) were used to describe the perception of students based on the application’s attributes. Paired t-test was utilized in order to assess the significant difference in the performance of students based on their pre-test and post-test scores.
Results. Based on the findings, students perceive all the attributes of the application to be ‘very high’ in terms of its accessibility (4.84 ± .22), enhancement factor (4.71 ± .27), motivational factor (4.65 ± .35), and objectives (4.78 ± .33). After the paired t-test analysis, a significant difference was observed between the scores of the students. The findings uncovered that students’ post-test scores are significantly higher (32.44) compared to pre-test scores (19.56) with a mean difference of 12.88 (p = .001).
Conclusions. Kahoot! is an effective pedagogical tool to be used for teaching and learning lecture-based concepts in Physical education. Recommendations for teachers and future research directions were also presented as a result of this investigation.

Published: February 2023

Background and Study Aim. Courage in sports is a concept that has attracted a lot of attention in recent years. It is very important for the athletes to reveal their psychological performance as well as their physical and technical skills during competition and or training times. In this context, this research is important in terms of revealing the mental endurance and courage levels of canoe athletes who struggle not only with their competitors but also with natural conditions.
Material and Methods. The sample of the research consists of 163 volunteer canoe athletes selected by simple random sampling method. In order to collect the necessary data in the research, the “Courage in Sports Scale” was used. The scale consists of the sub-dimensions of 'competence', 'determination', 'aggression', 'taking the risk' and 'being self-sacrificing'. T-test and ANOVA test were used in the analysis of the data. Statistically, the error level was accepted as p<.05 and the significance level was Alpha (α).
Results. In the study, it was determined that the perception scores of the athlete students between the courage scale components were close to each other. No statistically significant results were found in all sub-dimensions according to gender and weekly training duration variables. According to the age variable: a significant result was determined in the dimensions of determination and assertiveness, and in the dimensions of stability according to the variable of doing sports. According to the education variable, it was determined that there was no significant difference in the risk-taking sub-dimension. There were significant differences in the other sub-dimensions.
Conclusions. Without ignoring the acquisition of skills such as courage, it should be included in education and training programs from an early age and supported by sports training. Courage issues should be included in the training programs of educators (coaching training courses, seminars, etc.) and their importance should be emphasized.

Published: February 2023

This study aimed to decode the potential bioactive compounds and action mechanism of Hippophae rhamnoides in treating Sjögren’s syndrome using network pharmacology and molecular docking approach. The Traditional Chinese Medicine Systematic Pharmacology Database and Analysis Platform (TCMSP) and HERB (a High--throughput Experiment- and Reference-guided database of TCM) database were used to identify the active components of -Hippophae rhamnoides and their targets. Databases, including GeneCards, Online Mendelian Inheritance (OMIM), and DisGeNET, were used to acquire the major targets of action in Sjögren’s syndrome. Venn diagrams were constructed to identify the compound gene targets. Then the Search Tool for the Retrieval of Interacting genes/proteins database (STRING) platform was used to build a protein–protein interaction (PPI) network to analyze the potential protein functional modules. Analysis of Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) was performed through the Metascape platform to predict their biological processes and decipher the mechanism of action. The drug component–target–action pathway network was constructed through the Cytoscape 3.8.2 software. Furthermore, the AutoDock Vina software was used to perform molecular docking of core components and key targets, validating binding affinity between potential core components and key targets. Twenty-two Hippophae rhamnoide candidate compounds and 208 potential targets for Sjögren’s syndrome were acquired. The network analysis showed that the core active ingredients of Hippophae rhamnoides in regulating Sjögren’s syndrome were quercetin, kaempferol, and beta-sitosterol (β-sitosterol). Core targets included albumin (ALB), epidermal growth factor receptor (EGFR), Caspase-3 (CASP3), peroxisome proliferator-activated receptor gamma (PPAR-gamma or PPARG), estrogen receptor (ER) ESR1, heat shock protein HSP 90-alpha, EC 3.6.4.10 (HSP90AA1), plasminogen, EC 3.4.21.7 (PLG), MAPK14, MAPK8, and MAPK1. The KEGG analyses demonstrated that Hippophae rhamnoides could exert their functioning against Sjögren’s syndrome by reacting with the lipid and atherosclerosis signaling pathway and tumor necrosis factor (TNF) signaling pathway. Further, molecular docking analysis suggested that 10 compounds of Hippophae rhamnoides could be effective to treat Sjögren’s syndrome by matching five core genes to docking pockets. This study indicated that Hippophae rhamnoides’ functioning effects on Sjögren’s syndrome could be attributed to the regulation of a network comprising multi-targets, multi-compounds, and multi-pathways.

Published: February 2023

This study was undertaken to determine a statistical correlation between the role of time management and the academic performance of the college students during a pandemic. The population of the research consisted of distance learning students from the Department of Technology Teacher Education of Mindanao State University-Iligan Institute of Technology. One hundred eighty-two participants belonging to different courses who were selected randomly, ranging from first year to fourth year, participated conveniently in this study. Survey questionnaires regarding time management on a five-point likert scale were used to collect data from respondents and were disseminated through Google forms. Before utilizing scales, professionals in the field review them for validity. The variables' previous GPA correlated with .139 and a significance of .061 indicated that they have no significant relationship with how students manage their time. It is concluded that both variables have no significant relationship with each other and time management skills do not affect students' school performance significantly. However, students should be aware of time wastage and take responsibility for enhancing their time management skills and maintaining their grade point average.

Published: February 2023

SummaryIn well stimulation operations, the ability to sustain long-term conductivity of hydraulic/acid fractures defines an efficient and effective hydrocarbon production operation. However, it is challenging to keep the fracture conductive in the soft and weak carbonate formations due to many challenges. For example, the plastic deformation of rocks causes proppant embedment or asperities failure, resulting in fracture conductivity reduction. Consolidating chemicals, particularly diammonium hydrogen phosphate (DAP), have shown to be effective in rock consolidation and could reduce the decline in fracture conductivity if applied to carbonate formations. The previous research tested DAP at ambient conditions, whereas this work involves studying the hardening properties of DAP at reservoir conditions. The solutions with two initial concentrations (1 and 0.8 M) were tested at 77°F (ambient), 122°F, and 176°F. Furthermore, a post-treatment analysis was conducted to compare the performance of the chemical under different conditions. The analysis included understanding the changes in carbonate rocks’ (limestone and chalk) hardness (impulse hammer test and indentation test), porosity (helium porosimeter), permeability (steady-state and unsteady state nitrogen injection), and mineralogy [X-ray diffraction (XRD) and scanning electron microscopy (SEM)]. Results demonstrated that both rock lithologies reacted efficiently with the DAP solution, presented in terms of the noticeable improvements in their hardness. The elevated temperatures positively affected rock hardness, leading to a more than 100% increase in hardness for most samples. After obtaining successful results from experiments at various temperatures, the pilot American Petroleum Institute (API) conductivity experiments were conducted, testing the conductivity sustenance through the rock hardening concept. Preliminary API conductivity experiments have demonstrated that treated rock samples with DAP provided higher conductivity values than the untreated samples at high stresses. The results shown in this study provide a good foundation for further studies on the implementation of DAP in actual acid/hydraulic fracturing field operations.

Abstract
Stellaria media (L.) Vill. is widely distributed throughout the world and is traditionally used to treat inflammatory, respiratory, cardiovascular, and gastrointestinal diseases. This study was designed to phytochemically characterize and investigate the anti-ulcer activity of methanol extract of S. media (SME) in piroxicam (PRX)-induced gastric ulcer in rats. The plant extract was subjected to qualitative as well as quantitative analysis (HPLC and FT-IR) to elucidate the phytochemical composition. In vitro, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay was done to determine the antioxidant capacity. In 14 days of animal study, PRX (30 mg/kg, i.g.) was co-administered with omeprazole (OMP; 20 mg/kg, i.g.) as a standard gastroprotective drug and SME at 150, 300, and 450 mg/kg, i.g., respectively. The gastric pH, acid volume, acidity, ulcer score, hematological parameters, and serum levels of oxidants/antioxidants were determined along with histopathological studies of gastric tissue. Phytochemical analysis showed the presence of considerable phenolic and flavonoid contents which was corroborated with a significant DPPH radical scavenging (IC50: 27.94 µg/mL) activity of extract. Administration of SME at 150, 300, and 450 mg/kg exhibited a dose-dependent gastroprotective effect evidenced by an increase in gastric pH and acidity but a decrease in gastric acid volume, gastric ulcer score, and ulcer index. Treatment with SME normalized the altered hematological parameters and reduced the oxidative stress by decreasing serum levels of TOS and MDA, and increasing the TAC and CAT levels. In addition, histopathological findings supported the aforementioned results. This study concludes that Stellaria media has promising gastroprotective activity against PRX-induced gastric ulcer.
