Authors: McGavin Robert L. , Nguyen Hoan H. , Gilbert Benoit P. , Dakin Tony , Faircloth Adam
Published: April 2023

Rotary veneers from spotted gum (Corymbia citriodora) and white cypress pine logs (Callitris glaucophylla) recovered from the native forest in Queensland, as well as Queensland plantation hoop pine (Araucaria cunninghamii) logs were used to manufacture LVL products following six different lay-up strategies including blended species LVL. The different lay-up strategies were to determine the opportunities for improving the mechanical performance of plantation softwood LVL by including native forest veneers. The manufactured products were evaluated for their bending performance, tension, bearing strength perpendicular to the grain, and longitudinal-tangential shear strength. The all-spotted gum LVL showed superior performance in all testing compared to other construction strategies. Blending even a small amount of spotted gum veneer with plantation hoop pine veneer resulted in improved mechanical performance, especially in flatwise bending. Opportunities exist to develop more optimised construction strategies that target specific product performances while optimising the use of the variable veneer qualities generated from log processing.

Published: April 2023

The feasibility of performing finger jointing of green rubberwood was considered with typical adhesives used for gluing kiln-dried wood. The effect of initial moisture content of rubberwood (12 ± 1.1%, 37.6 ± 3.2%, and 61.2 ± 6.1%), hot air oven-drying temperatures (60 °C, 80 °C, and 100 °C), and types of adhesives (polyurethane (PU) and emulsion polymeric isocyanate (EPI)) on bending and compressive properties of finger jointed rubberwood products were investigated. The controls were manufactured from 12 ± 1.1% moisture content rubberwood. The type of adhesives had no significant effect on the examined properties of the finger-jointed specimens. The initial moisture content had a slight effect on the modulus of rupture (MOR) and modulus of elasticity (MOE) of specimens bonded with EPI adhesive. The MOR of all types of specimens bonded with EPI adhesive were slightly lower, but their MOE tended to be slightly higher than the control. The drying temperature slightly improved the MOE of specimens bonded with EPI adhesive. The result suggests that the finger jointing process of green rubberwood using typical adhesives could be performed without notably reducing the strength of the final products compared with the control.

Published: April 2023

In the biomedicine field, three-dimensional (3-D) printing of biomaterials can construct complex 3-D biological structures such as personalized implants, biodegradable tissue scaffolds, artificial organs, etc. Therefore, nanocellulose/gelatin composite hydrogels are often selected as bio-printing materials in the 3-D printing of biological scaffolds. Process parameters of 3-D printed bio-scaffolds were studied in this work because formation accuracy of scaffolds is an important part of the molding process. Firstly, the mixing proportion of nanocellulose and gelatin was explored, and the optimum proportion was selected. Then, the printing effects of different printing pressures, temperatures, speeds, and nozzle diameters were used in the 3-D printing. The filament widths were used to evaluate the molding effects. Finally, through the calculation and analysis of the grey correlation coefficient and grey correlation degree, the multi-objective optimization of the parameters was carried out. The combined effects of the process parameters and the influence degree order on the evaluation index were obtained. Using these parameters, the 3-D porous biological scaffolds were printed with high precision. Furthermore, using a microscope, the morphologies of CCK-8 cells were observed and the cell proliferation were analyzed. The results demonstrated that the printed bio-scaffolds had good biocompatibility.

Tar is an undesirable product of biomass gasification. Tar analysis is a challenging task because it is a complex mixture. The objectives of this study are to identify and quantify the major tar compounds in raw producer gas and deposits from a 10 kW downdraft gasifier using cedar pellets. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the 16 tar samples from raw producer gas under varying airflow rates and four tar samples from the deposit inside the suction pump after long-term operation. The results showed that tar in raw producer gas and tar deposits consisted of about 46 and 28 major chemical compounds, respectively. Tar in raw producer gas was found to contain three main groups of substances, including acids/ketones with 32.1 wt%, heterocyclics with 30.0 wt%, and light poly-aromatic hydrocarbons (light PAHs) with 31.8 wt%. Heterocyclic and light PAH compounds dominated in tar deposits and accounted for 58.6 wt% and 36.2 wt%, respectively. It was observed that the tar condensation problem was dominated by the components and the molecular weight of tar compositions instead of the tar concentration. These findings are useful for optimizing the gasification process and developing the gas cleaning system for a small downdraft gasifier.

Published: April 2023

Wood drying is an important stage in the woodworking process. After drying, wood is subject to a re-sawing process, for which a high quality surface, low material loss, and high efficiency are often required. In this paper, forecasted values were presented of cutting power for the re-sawing process of pine and beech wood that were dried with four different methods. Forecasting of cutting power for an industrial band saw machine that works daily in a Polish sawmill was determined. Values of cutting power were forecasted for a full range of feed speeds of the analyzed band saw machine. The achieved results allowed the observation of noticeable changes in the forecasted cutting power for a given sawing process as a function of the wood drying method applied. Significant changes were observed for pine wood, especially between air-dried pine wood and wood dried with warm air-steam mixture, and between pine wood dried in a conventional kiln and with warm air-steam mixture.

The emission of nitrous oxide is considerable in livestock systems, influenced by nitrogen fertilization and edaphoclimatic conditions. The aim of the research was to measure the flux of nitrous oxide (N2O) from the soil under Urochloa brizantha with nitrogen fertilization. In the pastures, a randomized complete block design was established with four replicates and three treatments, consisting of 2 m2 plots with U. brizantha fertilized with urea, bokashi and without fertilizer application. The gas samples were collected over three months between the rainy and dry seasons using the static closed chamber methodology. The samples related to the soil and plants were taken at a depth of 15 cm under undisturbed conditions every month, to quantify: gravimetric moisture, ammonium, nitrate, total carbon, total nitrogen, carbon/nitrogen ratio, and plant dry matter (DM). The ANAVA registered a significant difference between treatments for N2O, with the application of urea promoting higher accumulated flows (0.37 mg N2O m-2 h-1), followed by bokashi (0.34 mg N2O m-2 h-1) and lastly by the control (0.27 mg N2O m-2 h-1). The daily emission of the gas fluctuated in the rainy season, when soil moisture promoted higher emission peaks compared to the dry season. The fractions of nitrogen, carbon and DM were not affected by the treatments. The use of urea and the anaerobic conditions of soil due to the rains generated higher N2O values, while the organic amendment, bokashi, was the best alternative for the greenhouse gas mitigation and soil conservation.
Andrés Jolofo y el negro Roque: dos procesos de sucesión de la diáspora africana en el periodo esclavista de Antioquia, Nuevo Reino de Granada, 1657 y 1763
Authors: Vargas-Arana Paola , Yepes-Londoño Jorge-Humberto
Published: April 2023

los manuscritos aquí transcritos son dos piezas excepcionales de la historia de la diáspora africana en América que yacen en el Archivo Histórico de Antioquia. Aunque no aclaran si se trata de personas nacidas en África o en América, ambos se refi eren a hombres de piel oscura y ascendencia sociodemográfi ca africana, quienes vivieron en la provincia de Antioquia, Nuevo Reino de Granada, durante los siglos XVII y XVIII. El primero, de 1657, es el testamento de Andrés Jolofo un “negro horro”, o sea una persona que obtuvo la libertad durante su vida. Proponemos que el etnónimo Jolofo y los bienes que dejó son un puente para acercarnos tanto a la cultura Jolofo en África occidental, como a los registros de llegada de esta población al Nuevo Reino de Granada. La segunda transcripción es la mortuoria del negro Roque fallecido en 1763, la cual demuestra cómo las personas de la diáspora africana aprovechaban la porosidad del sistema esclavista pues, utilizando sus habilidades como negociante y constructor, Roque sorteó el estatus socio-jurídico que le impedía tener inmuebles por ser un esclavizado y llegó a adquirir casa y solar como peculio propio.
Honor, deshonra y justicia: injurias en la Real Audiencia de Santafé (1560-1662)
Authors: Gil-Yepes Julián-Andrés
Published: April 2023

el honor tuvo un rol fundamental en la jerarquización social de la cultura hispana, tanto peninsular como indiana, por lo cual se consolidó como uno de los pilares de la sociedad. Por este motivo la injuria tomó un importante papel en la vida cotidiana, y por eso permite analizar el honor antes, durante y después de una afrenta directa para observar la manera en la que este se ejercía, defendía, perdía y recuperaba. Este artículo dio cuenta de una investigación cualitativa y cuantitativa sobre la injuria en la Audiencia de Santafé (1560-1662), por medio de un análisis de los procesos criminales, el derecho indiano y el significado de los tipos de injurias. De este modo, se evidenció la manera diferencial en la que el honor fue ejercido por parte de hombres, mujeres, ofi ciales monárquicos y clérigos, con base en la manera en la que este fue vulnerado. Además, se identifi có que las injurias se servían de discursos conductuales, morales, religiosos, biológicos y de género. Los resultados dan pie a considerar a la injuria como un fenómeno cultural con una doble acepción, pues al mismo tiempo que representaba una transgresión del orden social, también terminó reproduciendo y fortaleciendo el mismo orden que transgredía.
El acceso a la libertad para la población esclavizada de la provincia del Chocó (Nueva Granada/Colombia) entre 1810 y 1851
Authors: Perdomo-Forero Yurany , Rodríguez-Caporalli Enrique
Published: April 2023

este artículo realizó una descripción cuantitativa de las vías por las que los esclavizados de la provincia del Chocó (Nueva Granada/Colombia) accedieron a la libertad entre 1810 y 1851. Para ello, se hizo una revisión documental de tres archivos históricos de los cuales se obtuvo un total de 1378 registros que permitieron crear una base de datos y organizar la información a partir de la siguiente propuesta de modalidades de libertad: libertad notarial, libertad por Ley de Manumisión de 1821 y fugas. Con esta recopilación se logró establecer que la principal vía para el acceso a la libertad de la población esclavizada en esta provincia fue por medio de la Ley de 1821. No obstante, estos casos se concentran en los dos últimos años de estudio (1850-1851), razón por la cual también cobra relevancia la libertad notarial de la que se encontraron mayores registros distribuidos en 28 años del periodo de análisis. Por otro lado, con respecto a las fugas se concluyó que, aunque su porcentaje como método de liberación fue mínimo, fueron en ocasiones una alternativa exitosa de resistencia al convertirse en medio para acceder a la libertad. La presencia de estas estrategias confi rma, además que, durante el periodo de estudio, los esclavizados estuvieron en constante búsqueda de su libertad y que no se limitaron únicamente a la propuesta republicana (Ley de Manumisión de 1821), la cual, como se demostró, solo tuvo un efecto realmente significativo en los dos últimos años de vigencia de la esclavitud (1850-1851).
Tierra: de tránsito por las ideas en la cultura occidental (siglos XVII al XIX)
Authors: Gutiérrez Felipe , Hernández Adolfo
Published: April 2023

el objetivo del artículo fue estudiar las transformaciones del concepto “tierra” como objeto de la ciencia moderna en Occidente. Metodológicamente, el texto recurrió a la historia de las ideas con el fi n de identifi car el tránsito de sus representaciones singulares entre los siglos XVII y XIX. Para tal fi n, se seleccionaron y compararon como fuentes los análisis desarrollados por algunos fi lósofos e historiadores de la ciencia como Giorgio Agamben, Michel Foucault, François Dagognet, Arthur Lovejoy y Stephen Jay Gould, entre otros. A partir de este revisión bibliográfi ca el artículo describió procesos de conocimiento implicados en esas derivas históricas de la idea de ciencia en la modernidad, por ejemplo, que el botánico de una hoja o un fruto, dedujo el árbol; el paleontólogo de un diente o un hueso, dedujo al animal; el nosólogo de un signo, derivó una patología; el geólogo de una roca, observó la tierra; el geógrafo de un escalonamiento temporal obtuvo la distribución espacial; el fi lólogo de la estructura de las palabras encontró el origen y composición de la cultura. De esta manera se concluyó que el conocimiento producido en estas ciencias del desciframiento, interesadas en la “lógica de lo viviente”, emergió en tensión con una teología cristianizante, dominante en Occidente, donde el Génesis planteaba una naturaleza creada desde el principio del mundo completa e inmutable, con sus mecanismos para regular la transformación. Sin embargo, la consideración de la variable tiempo hizo visible el espacio y este nuevo escenario llevó al surgimiento de teorías alternas como el preformismo y la epigénesis y a controversias como las que se tejieron desde el pensamiento científico en torno al cálculo de la edad de la tierra.
Ideario y accionar político de Antonio Nariño en la Nueva Granada: defensa de la soberanía popular, pragmatismo y autoritarismo (1810-1814)
Authors: Acevedo-Tarazona Álvaro , Rojas-López Estefanía
Published: April 2023

este artículo analizó la mutación en las posiciones políticas de Antonio Nariño en un periodo de incertidumbre y cambio entre 1810 y 1814. A partir del análisis de La Bagatela, el periódico fundado por Nariño en 1811, junto a los discursos, proclamas y misivas redactados por este en el ejercicio de su cargo como presidente del Estado de Cundinamarca, se mostraron las dos caras de este personaje, el prócer y el traidor, pero también las de una naciente opinión pública. Así, la trayectoria política de Nariño es el punto de partida para comprender la importancia de la prensa y de una primigenia opinión pública en la Nueva Granada en el siglo XIX, con sus dos caras: la de hacer circular ideas —formar opinión, llegar a un público cada vez más amplio—, pero también la de promover intereses personales, propagar divisiones, odios e ideas autoritarias. Se demostró que Antonio Nariño a través de sus escritos y su vida política se erigió como un crítico de las discusiones argumentadas por otros próceres, quienes propusieron soberanías que no eran viables para el territorio neogranadino. Además, se evidenció que la prensa se convirtió en un medio de opinión pública y de fomento del patriotismo en los ciudadanos neogranadinos.
A case report of acute bilateral bullous keratopathy in a septic calf

Published: April 2023

Bullous keratopathy occurs in dogs, cats and humans, and it is diagnosed by clinical and ophthalmic presentation. A 20 days old septic calf developed an acute bilateral ocular abnormality, with mild ocular discharge and corneal opacity. Slit-lamp biomicroscopy showed a severe central cornea oedema with a subepithelial bulla. The clinical diagnosis was bilateral bullous keratopathy; it was treated with glucose 35% ointment. After 2 weeks, corneal bullas were reabsorbed, and mild focal areas of corneal oedema were present bilaterally. Three weeks after discharging, the calf was hospitalised again for severe dyspnea, recumbency and depression and was euthanised due to worsening of clinical conditions. A necropsy was performed. Clinical signs, ophthalmic examination and histopathologic findings were suggestive of bullous keratopathy. Bullous keratopathy might be rare but due to the importance of predisposing diseases (i.e. septicaemia), early diagnosis and proper therapy could be useful to reduce farmers’ economic losses.
Chemicals management approach to sustainable development of materials
Authors: Ogunseitan Oladele A.
Published: April 2023

Throughout human history, the capacity to invent, manufacture, and use chemicals and materials has transformed concepts of development with path-dependent solutions to problems encountered in various industrial and societal sectors, including energy, transportation, food production, textiles, and personal care. It is increasingly clear that the trajectory of development initiated by some path-breaking materials is not sustainable. Recent developments in the concept of planetary boundaries have explored some reasons for unsustainability and ineffectiveness of current chemicals management practices. The reasons are almost always due to previously unknown chemical characteristics such as toxicity, reactivity, environmental recalcitrance, or increasing scarcity. In some cases, the suspected but ignored potential hazard of chemicals manifests slowly or becomes uncontrollable due to accumulation and biochemical or physical transformation in the environment. Consequently, environmental pollution by such chemicals is associated with alarmingly high levels of human mortality and disease burden worldwide. Recent examples include halogenated chemicals used as flame retardants and the thinning of the stratospheric ozone layer; bisphenol A used in plastics and microplastics widespread in biotic and abiotic ecosystem components, including the ocean; hormone mimicking chemicals such as phthalates in human tissues; neurotoxicity of lead used in solder materials, paints, and water distribution pipes; neurodevelopmental diseases associated with mercury used in ore beneficiation, in dental amalgams and lighting systems; and asbestos fibers used in ceiling tiles, roofs, and automobile brakes. These notorious examples have forced the introduction of retroactive policies to restrict the use of certain chemicals in materials development, and a few proactive policies designed to prevent the initial use of certain chemicals known or suspected to be hazardous. Improvements in the scientific knowledge and development of tools to screen for chemicals of concern have also led to the development of forecasting tools for improved management of chemicals. It could be impossible to foresee all potential risks associated with chemicals. Therefore, such management approaches can be most effective in supporting sustainable development of materials when they generate boundaries within which criteria for safety are understood and alternative assessments are continuous. This article situates the power of selected forecasting tools for early warning systems in a planetary boundary framework while highlighting gaps and incongruencies inherent in their use to support proactive and reactive regulatory policies, and for developing performance standards for lowering the chemical footprint of consumer products.

Graphical Abstract
Entanglements: Marking Place in the Field of Religion
Authors: McCutcheon Russell T.
Published: April 2023

Entanglements attempts to argue against those who claim that scholarship on the category religion is only of secondary interest, in that it fails to do primary research on real religions. The volume collects eighteen responses, written across twenty years, that each exemplify the inevitably situated, give-and-take nature of all academic debate. These essays call into question the often used distinction between primary and secondary sources, between description and analysis. Published here in their original form, each contribution is accompanied by new, substantive introduction describing the context of each response and explaining how each shows something still at stake in the academic study of religion–whether its the rhetoric used to authorize competing scholarly claims or the difficulty involved in suspending our commonsense view of the world long enough to study the means by which we have come to see it that way. An ethnography of scholarly practice written mainly for earlier career readers–whether undergraduate or graduate students or even tenure-track faculty–Entanglements tackles the notion that some scholarship is more pristine, and thus more valuable, than others, thereby modeling for scholars earlier in their careers some of the obstacles and arguments that may face them should their research interests be judged unorthodox.

Authors:   Perm Scientific-Industrial Instrument Making Company, Gilev D.G.
Published: April 2023

In the work, a fiber-optic resonator (FOR) was studied, which is used as a sensitive element of the angular velocity sensor. The measured operating parameters of the RVO are given and the dependence of the resonant frequency shift on the angular velocity is found. The developed layout made it possible to measure the minimum sensitivity to the angular velocity of this resonator and to evaluate the maximum measurement range. An estimate of the angular velocity measurement range gives values from minus 600,000 °/s to minus 10 °/s and from 10 °/s to 600,000 °/s.

This case study focused on zero emission via waste sludge treatment process from a brewery wastewater treatment plant. A perspective solution was based on three main processes by sludge digestion (40 m3/day), biogas recovery and purification for generation (20 kWh) and organic fertilizer production for green agriculture. The system is designed to integrated processes and operated autocompletively, except for the fertilization of crops. This work results showed that organic content decreased 55 - 70% after 20 days of sludge retention time (SRT) with 55 - 65% methane (CH4) yield. The contaminants in biogas was purified by high gravity rotating packed bed (HGRPB) device using aqueous solution (NaOH 0.01 M) and removal efficiency of CH4 concentration is 87%, this CH4 content met a demand of the standard for generator engines or boiler combustion. The digested sludge was combined with other by-products to produce organic fertilizer for green agricultural development, the quality of organic fertilizer was examined and met the regulations of Decree No. 84/2019/ND-CP of the Government: Regulations on fertilizer management. The achievements of this case study respond the harmonious combination among waste treatment, energy recovery and organic fertilizer production to contribute to the direction of the circular economy aspect and sustainable development.

Authors: Nguyen Khang
Published: April 2023

Drones are increasingly being used in surveillance, agriculture, and delivery tasks. However, the real-life application of images collected from drones in urban manage- ment in Vietnam is still limited. Although drone images have many advantages thanks to the flexibility of the latest devices, there are still new challenges, such as top-down views, small objects, arbitrary directions, and class imbalance. In this paper, we conduct research, survey, and evaluate the performance of CNN-based network architectures on object detection in aerial images. Experiments were conducted on seven deep learning network architectures: VGG, ResNet, ResNext, Res2Net, ResNeSt, HRNet, and RegNet to bring objective judgments and conclusions based on experiments, contributing to the development of solutions for applications of determining the status of urban traffic in Vietnam.

Published: April 2023

This systematic review focuses on issues and challenges related to pre-service English teachers (PSETs) in Malaysia for the past decade. Even though improving English language teachers’ quality is a primary agenda in the Malaysian Education Blueprint 2013-2025, review studies documenting the recent issues and developments of pre-service teachers who are just joining the teaching profession are still lacking. Combining Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) with published review guidelines, the review utilised seven databases to look for current research. Subsequently, the final search yielded twenty articles for the qualitative synthesis using ATLAS.ti. It has been determined that the PSETs in Malaysia experience issues and challenges in terms of (1) teaching competency; (2) professional development; (3) support; (4) the disparity between theories and classroom practices; (5) classroom management and (6) transition stage in becoming a teacher. This study concludes that future teacher education needs to prepare trainee teachers to be more resilient and adaptable to new environments, challenges and unforeseen circumstances. Finally, several recommendations were highlighted for further studies.
EMERGENCY REMOTE TEACHING IN INDONESIA: A MISSED OPPORTUNITY FOR GREATER LEARNER AUTONOMY
Authors: Defianty Maya , Wilson Kate
Published: April 2023

The sudden switch to learning from home during the COVID-19 pandemic impacted teachers across the world. In Indonesia, schools were closed from early March 2020 onwards. This paper presents the findings of a qualitative research project that investigated how Indonesian teachers of English responded to the challenges of Emergency Remote Teaching (ERT) and whether ERT would lead to greater learner autonomy. Ten teachers responded to an invitation to participate in focus groups and individual interviews on Zoom and to contribute examples of their lesson plans from the lockdown period. All teachers found that WhatsApp was the most efficient and effective platform for remote teaching, allowing synchronous and asynchronous sharing of audio, video and text-based materials. Despite the challenges of poor connectivity and lack of face-to-face contact, the teachers were able to continue involving their students actively in integrated, communicative tasks that pushed them to extend their communicative competence. Unexpectedly, however, the move to online teaching did not herald a shift towards greater learner autonomy. The data from this research shows that English language teaching in Indonesia is still firmly teacher-controlled despite the affordances of online learning.
ENGLISH LEARNING GOALS AND WILLINGNESS TO COMMUNICATE: A QUALITATIVE ANALYSIS IN A JAPANESE EFL CONTEXT
Authors: Fujii Satomi
Published: April 2023

This study examined the differences in English learning goals and specific actions for goal achievement according to the degree of willingness to communicate (WTC) among Japanese English as a Foreign Language (EFL) learners through qualitative analysis. This study aimed to ascertain: 1) the characteristics of English learning goals among learners with higher or lower levels of WTC, and 2) the differences in learner actions for goal achievement among learners with higher or lower levels of WTC. The participants were 84 undergraduate students in Japan, and they were divided into high-WTC and low-WTC groups using the WTC scale (Peng & Woodrow, 2010). Open-ended responses of the goals for learning English and actions for goal achievement were compared between these two groups using KH Coder 3. Coded data were analyzed in a co-occurrence network diagram. Results showed that high-WTC learners tended to have high-level goals, whereas low-WTC learners tended to have the lowest possible goals. High-WTC learners also had more interest in foreign countries and studying abroad. Furthermore, high-WTC learners tended to take a variety of specific actions for goal achievement, while low-WTC learners took rather general and common actions. The results showed clear differences between these two groups.

Aim. To analyze the level of biomarkers of inflammation and endothelial dysfunction in elderly patients with myocardial infarction (MI), hypertension (HTN) and frailty.

Material and methods. Three following clinical groups were formed: patients aged 60-74 years with MI+ grade 1-2 HTN (n=80); patients aged 60-74 with MI+HTN+prefrailty (n=52); patients aged 60-74 years with MI+HTN+frailty (n=114). In patients of all groups 2-4 months after MI, the levels of high-sensitivity C-reactive protein (hsCRP), intercellular adhesion molecule 1 (ICAM-1), nitric oxide (NO) metabolites — nitrates and nitrites, endothelin-1, desquamated endotheliocytes, vascular endothelial growth factor (VEGF) were determined.

Results. Patients with MI+HTN+frailty had a higher hsCRP — 6,4 mg/l compared with patients with MI+HTN+ prefrailty (4,2 mg/l; p<0,01) and patients with MI+HTN (3,2 mg/l; p<0,01). The level of ICAM-1 was 315,6, 242,7, and 213,5 ng/ml, respectively, in these groups (p<0,01). Patients with MI+HTN+prefrailty, MI+HTN+frailty and MI+HTN had following levels of nitrite (NO2-) and nitrate (NO3-) — 6,7, 5,4, and 7,2 pmol/l (p<0,01). A similar ratio is inherent in NO3-. On the contrary, the content of desquamated endotheliocytes and VEGF was significantly higher in patients with MI+HTN+frailty compared with patients with MI+HTN+ prefrailty (p<0,01). The level of endothelin-1 was also significantly higher in patients with MI+HTN+frailty compared with the MI+HTN+prefrailty group: 18,85 vs 13,41 fmol/l (p<0,05).

Conclusion. The levels of inflammation and endothelial dysfunction in patients with MI+HTN are significantly higher than those in patients with MI+HTN+frailty compared with patients with MI+AH+prefrailty and MI+HTN, with the exception of nitric oxide metabolites.

Austenitic and duplex stainless steels are majorly preferred for heat exchangers and chemical containers. This research work investigated the failure mechanism of dissimilar welded joints of AISI 347 and DSS 2205. The welded specimens were investigated using tensile shear tests, cross-tension tests, coach peel tests and microhardness tests. The specimen absorbed a maximum tensile shear load of 18 kN during the tensile shear test, and the failure mode was button pull-out with brittle fracture. The test sample absorbed a load of 15.1 kN during the cross-tension test, and the failure mode was button pull-out with brittle fracture. During the coach peel test, the sample absorbed a maximum load of 4 kN and ductile fracture was observed at the vicinity of the nugget. The failure mode in the coach peel test was of button pull-out type. The microhardness test recorded a maximum hardness of 312.8 HV, which is 78.74 and 7.1% higher than the base metal hardness values of AISI 347 and AISI 2205, respectively. The specimen failed under pull-out failure mode in all the tests, and hence, the weld zone was intact in all specimen arrangements and loading conditions.
Oblique DOM in enriched case hierarchies
Authors: Irimia Monica Alexandrina
Published: April 2023

This paper addresses syncretism patterns differential object marking (DOM) constructed with oblique morphology (dative, locative, genitive) induces cross-linguistically. It is shown that enriched case hierarchies (Starke 2017, Caha 2019, a.o.), which are also extended to ergative-absolutive systems, derive all these syncretisms. Enriched case hierarchies also capture crucial properties of the oblique DOM types discussed here: i) such categories have the syntax of direct objects, as types of structural accusatives, and not obliques, making their oblique appearance rather a matter of PF syncretism; ii) at the same time, oblique DOM can show syntactic differences from unmarked accusatives, motivating the need for more than one instance of the accusative in the hierarchy.

As cities work to accelerate sustainable-transport transitions, the expansion of cycling networks has become a significant topic of debate. Even as cycling mode shares are increasing across a number of North American contexts, ‘bikelash’ (i.e. community opposition to cycling facilities) remains prevalent. In this paper, we draw from qualitative questionnaire data and spatial analysis from Montréal, Québec to contribute a situated understanding of factors influencing both positive and negative social perceptions of cycling infrastructure. Our analysis confirms general trends that contribute to residents’ overall satisfaction with recent cycling interventions, including enhanced safety considerations and family-friendly infrastructure. We also identify particular sources of bikelash that require deeper consideration, including conflicting ideas about the impacts of cycling facilities on local businesses, divergent opinions about the planning process, perceived inequities in the distribution of cycling networks, as well as issues of seasonality and modal integration. These findings can be of interest to practitioners and decision makers working to support sustainable-mobility transitions, including recommendations on public communication and consultation processes, winter cycling facilities, integrated infrastructure for active travel, as well as the inclusion of social equity and critical disability perspectives.

Having caused a global pandemic in 2020, COVID-19 can be described as a paradigm-shifting event inmany aspects of modern life. The strict pandemic response in the beginning has gradually dissipatedover time as public support has declined. While different countries have had different approaches tomanaging COVID-19, all governments have fought a severe battle against fake news related to the virus,which in many cases has reduced the effectiveness of protection. The attitudes towards masking,lockdowns, and vaccination have become a political self-definition mechanism in many countries,influencing policy-making processes. Therefore, this study examines COVID-19-related fake news fromthree aspects: sentiment analysis, a network theory approach, and a survey.Keywords: COVID-19, sentiment analysis, fake news, network theory, survey
Discursos sobre violencia filio-parental en la red social Twitter
Authors: Palma-Durán José-Abdón , Ruiz-Callado Raúl
Published: April 2023

La violencia ejercida hacia los progenitores por parte de los descendientes adolescentes, conocida como violencia filio-parental (VFP), ha generado profundo interés durante la última década. Ello ha propiciado un incremento de la investigación y de los recursos públicos asignados a este fenómeno criminológico. El presente artículo analiza el discurso generado en la red social Twitter, con el objetivo de identificar los temas más tratados y los actores con mayor presencia pública e influencia sobre este tipo de violencia. Se analiza un corpus de 6146 tuits, lo que supone el total que incluye los términos filio-parental, filioparental o filio parental entre los años 2009 y 2022. Los datos muestran una actividad mayoritaria vinculada a la acción profesional y una influencia directa de los medios de comunicación tradicionales para marcar la agenda del discurso en esa red social. Ello ha resultado especialmente evidente tras la inclusión de contenidos relacionados con dicho tipo de violencia en programas de máxima audiencia de una televisión privada generalista en España, lo que ha supuesto una transformación cuantitativa y cualitativa del discurso en Twitter sobre la VFP.
Abstract
Violence against parents by adolescent offspring, known in Spain as violencia filio-parental (VFP), has generated a great deal of interest during the last decade, which has led to an increase in research and public resources allocated to this criminological phenomenon. This paper analyses the discourse generated in the social network Twitter with the aim of identifying the most discussed topics and the actors with a greater public presence and influence on this type of violence. For this purpose, a corpus of 6146 tweets has been analyzed, which represents the total number of tweets that include the terms filio-parental, filioparental or filio-parental between 2009 and 2022. The data shows a prevailing activity linked to professional actions and a direct influence of traditional media to set the agenda of the discourse in the social network. This has been especially evident after the inclusion of content related to this type of violence in prime-time programs of a generalist private television in Spain, which has led to a quantitative and qualitative transformation of the discourse on Twitter about child-to-parent violence.
L’impact de la crise sanitaire sur les métiers du care.
Authors: LOURS Caroline
Published: April 2023

À la suite de l’ethnographie d’une institution médico-sociale cet article tend à décrire les conditions de travail des professionnelles du médico-social pendant la crise du coronavirus. Je m’interroge tout d’abord sur les compétences nécessaires pour s’occuper de personnes considérées comme vulnérables du fait de leur handicap. Puis à l’impact de la crise sanitaire sur l’accueil des usagers souffrant d’un trouble du spectre autistique ainsi que sur la santé physique et mentale des éducatrices. De plus, les mesures étatiques, associées aux angoisses et aux difficultés physiques des professionnelles, ont mené à une politisation nouvelle dans ce secteur.
Contribution des medias sociaux à la prevention et à la lutte contre les violences conjugales. S'informer par les réseaux sociaux en temps de crise en Côte d'Ivoire.

Le déclenchement de la pandémie de la Covid-19 a amené les gouvernements africains à adopter une série de mesures visant à limiter la propagation du virus. Parmi ces mesures, figure celle du confinement et des restrictions de mouvement des populations qui ont eu, entre autres, pour corollaire la recrudescence des violences conjugales. Face à la recrudescence des violences faites aux femmes, l’État ivoirien à travers ses structures dédiées à la protection de la femme a mis en œuvre un ensemble de stratégies destinées à apporter une réponse efficace et efficiente aux violences basées sur le genre. Parallèlement aux mesures étatiques, se sont déployées sur les médias sociaux, des initiatives de sensibilisation, de dénonciation et prise en charge des VBG.
Cette étude se propose d’analyser la contribution des médias sociaux dans la prévention et la lutte contre les VBG en temps de crise sanitaire, comme celle de la Covid-19. Elle se déroule en Côte d’Ivoire et mobilise deux (02) techniques de collectes de données induisant chacune une technique d’analyse. La première technique fait référence à une analyse documentaire basée sur les statistiques et données dans le domaine des violences basées sur le genre durant les années 2018, 2019, 2020 et 2021. La deuxième technique consiste en une veille informationnelle et mobilise un corpus constitué des témoignages et réactions des populations sur les différents médias sociaux face aux cas de violences conjugales, sur les années 2020 – 2021. Les données recueillies sont ainsi analysées sous des aspects mixtes combinant le qualitatif et le quantitatif.
Les résultats de cette étude s’articulent autour de trois points clés. Le premier élément est relatif à la situation des violences conjugales avant et durant la période covid-19. Quant au second point majeur, il concerne la présentation du paysage des réseaux sociaux en Côte d’Ivoire. Enfin, le troisième axe des résultats est consacré à la mise en évidence des fonctions et rôles que revêtent les réseaux sociaux face aux violences conjugales en période de crise sanitaire.
Supernovae and gamma-ray burst connection
Authors: DELLA VALLE Massimo
Published: April 2023

I review the status of the Supernova/Gamma-Ray Burst connection. Two decades of observations have established that long-duration Gamma-ray Bursts are associated with very energetic SNe-Ib/c. These SN explosions are produced by the gravitational collapse of Wolf–Rayet progenitors, with masses on the main sequence, between 30–50 $M{\odot}$. Current measurements provide a GRB/SNe-Ibc ratio in the range $\sim$0.02–1.5$\%$,
so GRBs are very rare events, even when compared with the SN frequency. There is a minority fraction of long-duration GRBs with no accompanying SN that are likely produced during the merging of neutron star or white dwarf neutron star merger.
SPH simulations of the induced gravitational collapse

In the induced gravitational collapse (IGC) paradigm, a carbon–oxygen (CO) star collapses and explodes in a supernova (SN) in the presence of a binary companion, a neutron star (NS). The material ejected in the explosion is gravitationally attracted by the NS, triggering a hypercritical accretion process onto it. For compact systems, the accretion rate could be high enough for the NS to reach its critical mass, collapse in a black hole (BH) and emit an energetic (energy release $\gtrsim 10^{52}$ erg) gamma-ray burst (GRB). With the aim to identify the separatrix of systems in which a BH is formed and characterize the observational signatures of the above process, we have performed three-dimensional (3D) smoothed-particle-hydrodynamics (SPH) numerical simulations of the SN expansion in the presence of the NS companion and the evolution of the NS during the accretion process. We here summarize the results of the above simulations for a wide range of the initial conditions of the parameter space.
