We report the discoveries of a nuclear ring of diameter 10″ (∼1.5 kpc) and a potential low-luminosity active galactic nucleus (LLAGN) in the radio continuum emission map of the edge-on barred spiral galaxy NGC 5792. These discoveries are based on the Continuum Halos in Nearby Galaxies—an Expanded Very Large Array (VLA) Survey, as well as subsequent VLA observations of subarcsecond resolution. Using a mixture of Hα and 24 μm calibrations, we disentangle the thermal and nonthermal radio emission of the nuclear region and derive a star formation rate (SFR) of ∼0.4 M
☉ yr−1. We find that the nuclear ring is dominated by nonthermal synchrotron emission. The synchrotron-based SFR is about three times the mixture-based SFR. This result indicates that the nuclear ring underwent more intense star-forming activity in the past, and now its star formation is in the low state. The subarcsecond VLA images resolve six individual knots on the nuclear ring. The equipartition magnetic field strength B
eq of the knots varies from 77 to 88 μG. The radio ring surrounds a point-like faint radio core of S
6 GHz = (16 ± 4) μJy with polarized lobes at the center of NGC 5792, which suggests an LLAGN with an Eddington ratio of ∼10−5. This radio nuclear ring is reminiscent of the Central Molecular Zone of the Galaxy. Both of them consist of a nuclear ring and LLAGN.
Investigating the Accretion Nature of Binary Supermassive Black Hole Candidate SDSS J025214.67−002813.7

Published: March 2022

We present results of a multiwavelength analysis of SDSS J025214.67−002813.7, a system that has been previously classified as a binary active galactic nucleus (AGN) candidate based on periodic signals detected in the optical light curves. We use available radio−X-ray observations of the system to investigate the true accretion nature. Analyzing new observations from XMM-Newton and NuSTAR, we characterize the X-ray emission and search for evidence of circumbinary accretion. Although the 0.5–10 keV spectrum shows evidence of an additional soft emission component, possibly due to extended emission from hot nuclear gas, we find the spectral shape is consistent with that of a single AGN. Compiling a full multiwavelength spectral energy distribution (SED), we also search for signs of circumbinary accretion, such as a “notch” in the continuum due to the presence of minidisks. We find that the radio–optical emission agrees with the SED of a standard, radio-quiet, AGN; however, there is a large deficit in emission blueward of ∼1400 Å. Although this deficit in emission can plausibly be attributed to a binary AGN system, we find that the SED of SDSS J0252−0028 is better explained by emission from a reddened, single AGN. However, future studies of the expected hard X-ray emission associated with binary AGNs (especially in the unequal-mass regime) will allow for more rigorous analyses of the binary AGN hypothesis.
Robust Absolute Solar Flux Density Calibration for the Murchison Widefield Array

Published: March 2022

Sensitive radio instruments are optimized for observing faint astronomical sources, and usually need to attenuate the received signal when observing the Sun. There are only a handful of flux density calibrators that can comfortably be observed with the same attenuation setup as the Sun. Additionally, for wide field-of-view (FoV) instruments like the Murchison Widefield Array (MWA) calibrator observations are generally done when the Sun is below the horizon, to avoid the contamination from solar emissions. These considerations imply that the usual radio interferometric approach to flux density calibration is not applicable for solar imaging. A novel technique, relying on a good sky model and detailed characterization of the MWA hardware, was developed for solar flux density calibration for MWA. Though successful, this technique is not general enough to be extended to the data from the extended configuration of the MWA Phase II. Here, we present a robust flux density calibration method for solar observations with MWA independent of the array configuration. We use different approaches—the serendipitous presence of strong sources; detection of numerous background sources using high dynamic range images in the FoV along with the Sun; and observations of strong flux density calibrators with and without the additional attenuation used for solar observations—to obtain the flux scaling parameters required for the flux density calibration. Using the present method, we have achieved an absolute flux density uncertainty ∼10% for solar observations even in the absence of dedicated calibrator observations.
Fast Radio Bursts by High-frequency Synchrotron Maser Emission Generated at the Reverse Shock of a Powerful Magnetar Flare
Authors: Khangulyan D. , Barkov Maxim V. , Popov S. B.
Published: March 2022

We consider a magnetar flare model for fast radio bursts (FRBs). We show that millisecond bursts of sufficient power can be generated by synchrotron maser emission ignited at the reverse shock propagating through the weakly magnetized material that forms the magnetar flare. If the maser emission is generated in an anisotropic regime (due to the geometry of the production region or presence of an intense external source of stimulating photons), the duration of the maser flashes is similar to the magnetar flare duration even if the shock front radius is large. Our scenario allows for relaxing the requirements for several key parameters: the magnetic field strength at the production site, luminosity of the flare, and the production site bulk Lorentz factor. To check the feasibility of this model, we study the statistical relation between powerful magnetar flares and the rate of FRBs. The expected ratio is derived by convoluting the redshift-dependent magnetar density with its flare luminosity function above the energy limit determined by the FRB detection threshold. We obtain that only a small fraction, ∼10−5, of powerful magnetar flares trigger FRBs. This ratio agrees surprisingly well with our estimates: we obtained that 10% of magnetars should be in the evolutionary phase suitable for the production of FRBs, and only 10−4 of all flares are expected to be weakly magnetized, which is a necessary condition for the high-frequency maser emission.

Published: March 2022

For the Neotropical genusAngiopolybiaAraujo 1946, several phenotypic forms were previously described, however, they have not been studied within an integrative taxonomic framework. Here, we used molecular data (variation of two mitochondrial genetic markers with molecular species delimitation methods) and morphology (adult morphology, male genitalia, and scanning electron microscopy images) to test the number of species withinAngiopolybia. Specifically, we investigated the taxonomic validity of the morphological variantsA. pallensdark morph,A. paraensismorphparaensis,A. paraensismorphruficornis, andA. paraensismorphobscurior. Moreover, we reviewed the taxonomy and geographic distribution of the genus. Our results of morphological and molecular analyses are compatible with the current classification ofAngiopolybia, and we did not find reasons to propose the morphological variants ofA. pallensandA. paraensisas valid species. Additionally, we reassess the spatial range of the fourAngiopolybiaspecies and provide refined maps of their geographical distributions.
Multiplicity of nodal solutions in classical non-degenerate logistic equations
Authors: Cubillos Pablo , López-Gómez Julián , Tellini Andrea
Published: March 2022

This paper provides a multiplicity result of solutions with one node for a class of (non-degenerate) classical diffusive logistic equations. Although reminiscent of the multiplicity theorem of López-Gómez and Rabinowitz [1, Cor. 4.1] for the degenerate model, it inherits a completely different nature; among other conceptual differences, it deals with a different range of values of the main parameter of the problem. Actually, it is the first existing multiplicity result for nodal solutions of the classical diffusive logistic equation. To complement our analysis, we have implemented a series of, very illustrative, numerical experiments to show that actually our multiplicity result goes much beyond our analytical predictions. Astonishingly, though the model with a constant weight function can only admit one solution with one interior node, our numerical experiments suggest the existence of non-constant perturbations, arbitrarily close to a constant, with an arbitrarily large number of solutions with one interior node.

In this paper, we propose a numerical scheme to solve generalized space fractional partial differential equations (GFPDEs). Besides, the proposed GFPDEs represent a great generalization of a significant type of FPDEs and their applications, which contain many previous reports as a special case. Moreover, the proposed scheme uses shifted Chebyshev sixth-kind (SCSK) polynomials with spectral collocation approach. The fractional differential derivatives are expressed in terms of the Caputo's definition. Furthermore, the Chebyshev collocation method together with the finite difference method is used to reduce these types of differential equations to a system of algebraic equations which can be solved numerically. In addition, the classical fourth-order Runge-Kotta method is also used to treat the differential system with the collocation method which obtains a great accuracy. Numerical approximations performed by the proposed method are presented and compared with the results obtained by other numerical methods. The introduced numerical experiments are fractional-order mathematical physics models, as advection-dispersion equation (FADE) and diffusion equation (FDE). The results reveal that our method is a simple and effective numerical method.

V članku so predstavljene posebnosti fotografij, posnetih s pametnimi telefoni in njihov potencial za zbiranje prostovoljnih geografskih informacij. Ločljivost in jasnost fotografij, posnetih s pametnim telefonom, je danes že enakovredna fotografijam posnetih s kompaktnimi digitalnimi fotoaparati, hkrati pa omogočajo sprotno shranjevanje lokacije fotografiranja. Na primeru obdelave posamezne fotografije s pomočjo interaktivne orientacije, so te prednosti ovrednotene z vidika njihovega potenciala za fotogrametrični zajem, ob ažuriranju topografskih kart. Kljub dobrim potencialom, pa na koncu obseg zornega polja fotografije odloča o tem ali bomo iz take fotografije lahko izmerili merske 3R-prostorske podatke.

This article presents the characteristics of smartphone images and their potential for collecting the volunteered geographic information. Today the smartphone image quality is equivalent to those taken with compact digital cameras, and they allow the real-time storage of the location from where the image was taken. Taking the example of processing a single image by using interactive orientation, these advantages are evaluated in terms of their potential for photogrammetric measurements when updating topographic maps. Despite the promising potential, the field of view extent of an image ultimately determines whether we will be able to extract metric spatial 3D data from such an image.
Protagonisti socialne geografije: začetki
Authors: Gosar Anton
Published: March 2022

V geografiji je razlaga in opis prostorske stvarnosti v 20. stoletju doživljala različne raziskovalne pristope in opredelitve. Okroglo stoletnico praznuje socialnogeografsko nazorsko dojemanje procesov v kulturni pokrajini. V drugi polovici stoletja se je v okviru družbene oziroma kulturne geografije tudi v Sloveniji/Jugoslaviji pričelo uveljavljati prepričanje, da ima pri izgledu in funkciji določene pokrajine najbolj pomembno vlogo družba oziroma človek z njemu lastnimi interesi. Pot k takemu prepričanju so tlakovale osebnosti v Evropi in Severni Ameriki. Tovrstno teorijo in raziskovalno metodologijo so nekateri slovenski geografi, po avstrijsko-nemškem vzoru, vneto zagovarjali, drugi pa – predvsem zaradi skoraj izključnega zanikanja naravnogeografskih dejavnikov – nasprotovali. Na nasprotnih bregovih sta si s somišljeniki stala Svetozar Ilešič, zagovornik enovite/regionalne geografije in Vladimir Klemenčič, pobudnik »slovenske/ljubljanske šole socialne geografije«.

In geography of the 20th century, the interpretation of the existing spatial reality experienced different research approaches and definitions. Geographers came to the conclusion that society, man and social groups play also an important role in the contemporary appearance and function of a region. The path to such a belief has been paved before WW2 by several geographers in Europe and North America. Following the Austro-German model this theory and research methodology was in Yugoslavia advocated predominantly by Slovene geographers, while others – mainly due to the almost exclusive denial of the spatial physical-geographical factors – opposed it. Vladimir Klemenčič, the initiator of social geography thought in Slovenia, and Svetozar Ilešič, an advocate of the unified/regional geography, stood on opposite banks with like-minded people.
Analysis of visual elements of leisure attractiveness of Slovenian landscapes
Authors: Cigale Dejan
Published: March 2022

This paper discusses the attractiveness of the Slovenian landscape as a leisure space. It focuses in particular on relationship of attractiveness with landscape diversity and naturalness. As a starting point, the study of Perko et al. (2017) was used in which the authors identified the most and the least diverse Slovenian areas, i.e. landscape hotpots and coldspots. An online survey was conducted using photographs taken in selected hotspots and coldspots. Respondents were asked to rate the attractiveness of the landscapes shown in the photographs as destinations for a leisure trip. The attractiveness of the landscapes did not differ depending on whether they were in a hotspot or coldspot. On the other hand, the results clearly indicate the higher attractiveness of landscapes in which relatively natural landscape elements predominate.

Prispevek obravnava privlačnost slovenske pokrajine kot prostočasnega prostora. Posebej se osredotoča na povezavo privlačnosti s pokrajinsko raznolikostjo in naravnostjo. Kot izhodišče je bila uporabljena raziskava Perka in sodelavcev (2017), v kateri so avtorji določili najbolj in najmanj raznolika območja Slovenije, tj. pokrajinske vroče in mrzle točke. Izvedena je bila spletna anketna raziskava, v kateri so bile uporabljene fotografije, posnete v izbranih vročih in mrzlih točkah. Anketiranci so bili naprošeni, da ocenijo privlačnost pokrajin na fotografijah kot ciljev izletov. Privlačnost pokrajin se ni razlikovala glede na njihovo lego znotraj vročih ali mrzlih točk. Na drugi strani rezultati jasno kažejo večjo privlačnost pokrajin, v katerih prevladujejo razmeroma naravni pokrajinski elementi.
Demographic and Evolutionary History of Pallid and Shovelnose Sturgeon in the Upper Missouri River

Published: March 2022

Natural-origin Pallid Sturgeon Scaphirhynchus albus in the upper Missouri River are predicted to become extirpated as early as 2024. To aid in recovery efforts for this endangered species, we used genetic data from 17 microsatellite loci to infer demographic and evolutionary history of Pallid Sturgeon and a sympatric Shovelnose Sturgeon S. platorynchus. Our data indicated a recent sundering of geneflow between these species by overlapping allele size distributions at all loci and low level of genetic divergence (FST = 0.10). Tests for recent bottlenecks by using heterozygosity excess or allele frequency mode-shift tests indicated demographic stability for both species, while the M ratio identified that historic bottlenecks occurred in both species. Estimates of historical effective population size (Ne), based on coalescent modeling of allele size distribution, suggested that the geographic expansion of these species into the upper Missouri River during the late Pleistocene was associated with 10- to 19-fold reductions in Ne. By contrast contemporary estimates of Ne based on linkage disequilibrium revealed that Shovelnose Sturgeon (Ne = 2,983) had approximately 10 times greater Ne than Pallid Sturgeon (Ne = 254). Our results are consistent with the recent collapse of Pallid Sturgeon being caused by dam construction, which occurred between 1930 and 1965. Fortunately, genetic diversity remaining in this long-lived species provided an opportunity to conserve predam Pallid Sturgeon genetic diversity via a successful captive breeding program. We provide recommendations to address key conservation needs, including how to incorporate our estimate of Ne/adult census size of 0.26 (95% confidence interval of 0.16–0.47) into setting demographic recovery goals for Pallid Sturgeon.

Authors: Kengpol Athakorn , Punyota Wilaitip
Published: March 2022

According to the literature reviews on knowledge management, no evidence has been found on the knowledge management of vegetarian food among elderly people with chronic diseases. The objective of this research is to apply knowledge management in identifying appropriate vegetarian food for the elderly with chronic disease by using the deep convolutional neural network (DCNN). The contribution of this research is to enable people to use knowledge management and collect knowledge to create a machine learning algorithm system so that the elderly can access knowledge of vegetarian food in relation to chronic disease. The benefits of this research are that the elderly can learn to consume appropriate food based upon their chronic disease, and the food producers can provide food menus accordingly.

In recent years, wearable and mobile technologies have been applied in different domains such as medical, personal safety, sports, and lifestyle computing (Cheng & Mitomo, 2017). Wearable technologies may help users bring their experiences, engagements, and interactions from one context to another (Ching, Stewart, Hagood & Rashedi, 2016). These kinds of devices can be worn by people and they make it possible to enhance our lives. It is believed that wearable technology may also have a great impact on education because it could be adopted to foster educational experiences, inspire intrinsic motivation, and bring one close to youth culture and usage behavior (Larabi Marie-Sainte et al, 2016). However, there are few publications introducing wearable and mobile technologies within the framework of teaching, training, and learning.

Published: March 2022

Complex vesicovaginal fistulas present a unique challenge to surgeons, and surgical reconstruction outcomes may be suboptimal. The aim is to evaluate the patient’s characteristics as well as the factors influencing the functional outcome of complex vesicovaginal fistula surgical reconstruction. From 2016 to 2020, the medical records of 28 patients with complex fistulas were analyzed retrospectively. Means, ranges, and standard deviations were used in descriptive analysis. For categorical data, the Fisher exact probability test was used. The mean (standard deviation) age at presentation was 44.4 (10.04) years, while 85.7% (24) of patients were below 50 years of age. Hysterectomy was the most common aetiology in 21 (75%) patients, followed by radiotherapy in 3 (10.7%). Surgical repair success was seen in 24 (85.7%) patients. Four (14.2%) patients had an unsuccessful repair, one vaginal and three abdominal approach. All the failed abdominal repairs were radiation-induced fistula (p=0.001). Other factors that significantly influenced repair failure include vaginal mucosal atrophy (3 failures out of 8 patients, p=0.013), severe fibrosis around the fistula (4 failures out of 12 patients, p=0.024), non-placement of suprapubic catheter (2 failures out of 3 patients, p=0.006), and non-placement of interposition tissue flap (p=0.005). Hysterectomy and radiotherapy are the common causes of complex vesicovaginal fistula. The outcome of the repair is hampered by vaginal mucosal atrophy and severe scarring. The use of a suprapubic catheter and an interposition tissue flap improves the outcome. Post-irradiation fistula has a significant impact on repair outcome and necessitates special consideration for a comprehensive management strategy.

Published: March 2022

Purpose:

We report the outcomes of transperineal urethroplasty in patients with pelvic fracture urethral distraction defects (PFUDDs) over the past 12 years.

Materials and Methods:

Patients who received transperineal anastomotic repair of PFUDDs from January 2007 to December 2019 were retrospectively analyzed, specifically focusing on demographic findings, pelvic fracture type, urethral distraction defect length (based on retrograde urethrography and cystography), previous treatments, and ancillary maneuvers during surgery. Simultaneously, differences in clinical factors between successful and failed cases were also analyzed.

Results:

A total of 36 patients were included, with a final success rate of 83%. The mean age was 40.4 years, whereas the mean urethral distraction defect length was 31.9 mm. Most patients (69%) presented with unstable pelvic fractures. Treatment before referral included endoscopic treatment and urethroplasty in 13 (36%) and 2 cases (6%), respectively. For difficult cases, ancillary procedures, which included corporeal splitting (61.1%) and inferior pubectomy (8.3%), were performed. The postoperative average peak flow rate was 14.9 mL/s in the success group. Age and urethral defect length differed significantly between the success and failure groups.

Conclusions:

Over the past 12 years, transperineal urethral reconstruction demonstrated a success rate of 83% in 36 patients with PFUDD. Age and urethral defect length were identified as the two main factors affecting surgical prognosis.

Published: March 2022

Purpose:

To assess the clinical outcomes following dorsal buccal mucosal graft urethroplasty (BMGU) in perimenopausal women (PMW) suffering from urethral stricture disease.

Materials and Methods:

PMW (40–65 years) presenting with urinary symptoms were evaluated with uroflowmetry, voiding cystourethrogram (VCUG), and urethral calibration. PMW with maximum flow rate (Qmax) less than 10 ml/s or postvoid residual (PVR) volume greater than 50 ml, VCUG showing evidence of urethral stricture, and failure to calibrate with 14 Fr Foley catheter were included in the study. Patients with underactive bladder, carcinoma cervix, pelvic trauma, and oral submucosal fibrosis were excluded from the study. Patients satisfying inclusion and exclusion criteria underwent dorsal BMGU. Outcomes of the surgery were assessed by uroflowmetry at 3-monthly intervals.

Results:

The number of patients satisfying the inclusion and exclusion criteria between March 2014 and March 2020 was eight. The mean age of the patients was 52.1 years. The mean stricture length was 1.9 cm. The mean preoperative Qmax and PVR were 4.2 ml/s and 110 ml, respectively. The mean postoperative Qmax and PVR at 6 months were 15.4 ml/s and 39.1 ml, respectively. One patient had a recurrent stricture and underwent dilatation. Donor site complications were minor. The overall success rate of the procedure was 87%.

Conclusion:

Dorsal BMGU in females for urethral stricture disease offers successful urethral reconstruction and the advantage of least disruption of continence mechanism and resilience to hormonal changes in PMW.

Published: March 2022

Purpose Tyrosine kinase inhibitors (TKI) targeting vascular endothelial growth factor receptor (VEGFR) signaling pathways have been used for metastatic clear cell renal cell carcinoma (mCCRCC), but resistance to the drug develops in most patients. We aimed to explore the underlying mechanism of the TKI resistance with regard to programmed death-ligand 1 (PD-L1) and to investigate signaling pathway associated with the resistant mechanism.Materials and Methods To determine the mechanism of resistance, 10 mCCRCC patients from whom tumor tissues were harvested at both the pretreatment and the TKI-resistant post-treatment period were included as the discovery cohort, and their global gene expression profiles were compared. A TKI-resistant renal cancer cell line was established by long-term treatment with sunitinib.Results Among differentially expressed genes in the discovery cohort, increased PD-L1 expression in post-treatment tissues was noted in four patients. Pathway analysis showed that PD-L1 expression was positively correlated with the mammalian target of rapamycin (mTOR) signaling pathway. The TKI-resistant renal cancer cells showed increased expression of PD-L1 and mTOR signaling proteins and demonstrated aggressive tumoral behaviour. Treatment with mTOR inhibitors down-regulated PD-L1 expression and suppressed aggressive tumoral behaviour, which was reversed with stimulation of the mTOR pathway.Conclusion These results showed that PD-L1 expression may be increased in a subset of VEGFR-TKI–resistant mCCRCC patients via the mTOR pathway.

Ubiquitination is an ATP-dependent process that targets proteins for degradation by the proteasome. Here, we annotated 15 genes from the ubiquitin-proteasome pathway in the Asian citrus psyllid, Diaphorina citri. This psyllid vector has come to prominence in the last decade owing to its role in the transmission of the devastating bacterial pathogen, Candidatus Liberibacter asiaticus (CLas). Infection of citrus crops by this pathogen causes Huanglongbing (HLB), or citrus greening disease, and results in the eventual death of citrus trees. The identification and correct annotation of these genes in D. citri will be useful for functional genomic studies to aid the development of RNAi-based management strategies aimed at reducing the spread of HLB. Investigating the effects of CLas infection on the expression of ubiquitin-proteasome pathway genes may provide new information about the role these genes play in the acquisition and transmission of CLas by D. citri.

Supporting students’ transition into higher education: Motivation enhancement strategies
Authors: Kinsella Maurice , Wyatt John , Nestor Niamh , Rackard Sue , Last Jason
Published: March 2022

In this article, we explore first-year students’ transition into higher education (HE), focusing on the motivational factors that enhance their engagement. We argue that Student Support Professionals (SSPs) can play a pivotal role in heightening student motivation, given the broad range of academic, administrative, and pastoral responsibilities that this role entails. Against this background, we ask two questions: Firstly, how should we understand student motivation with specific regard to its antecedents, manifestations, and consequences? Secondly, what motivation-enhancement strategies can SSPs integrate into their practice to build a productive relationship with students? Drawing on self-determination theory (SDT) insights, we provide a taxonomy of student motivation, arguing that: Motivation exists in a continuum of self-regulation, motivation is contextual, motivation is multidimensional, and motivation is causally significant. Building on this taxonomy we offer practical guidance to SSPs who are looking to catalyse students’ intrinsic motivation, identifying three specific motivational enhancement strategies, namely: Fostering competence by establishing realistic expectations between oneself and students; fostering relatedness by providing resources for holistic student engagement; and fostering autonomy by empowering students in their decision-making. We argue that central to SSPs’ ability to foster engagement is possessing a conceptual and experiential understanding of student motivation, which can heighten their ability to respond to students’ needs. SSPs should approach this process of motivation enhancement as collaborative—working with students to discover both motivational impediments and motivation-enhancing resources to better engage with their HE experience.

The article presents the results of comparative tests on the wear resistance of composite materials (CM) sintered at high pressures and temperatures based on impact diamond (diamond-lonsdaleite abrasive — DLA) when processing silicon carbide (SiC). To assess the CM performance based on impact diamonds, a method has been developed for determining the wear resistance, based on the determination of the CM specific productivity. It is shown that for CMs based on impact diamond, it is expedient to use SiC as a binder. For CMs based on impact diamond with an additive of 40 vol.% SiC, specific productivity when machining a silicon carbide wheel is 25–30 % higher than for compositions containing dense BN phases — wBN and cBN. The decrease in the specific productivity of CM “impact diamond — cBN” relative to CM “impact diamond — SiC” is determined by the higher dispersion of crystals of dense BN phases in comparison with SiC, which generally impairs the abrasive ability of the material. In this case, the addition of a coarse fraction of impact diamond 100/63 μm to the charge composition does not lead to an increase in the specific productivity of the abrasive element as compared to CM based on DLA with a particle size of less than 40 μm. Preliminary mechanical activation of the initial charge also reduces the CM abrasive ability due to the formation of a highly dispersed structure of the material.

Environments for bathing and grooming procedures expose animals to a large number of stressors, such as dryer’s noise, changes in temperature and manipulation by strange people, causing apprehension, anxiety and fear that can lead to death due to physical trauma in attempts to escape or due to respiratory collapse secondary to acute stress. We report the case of a 6-month-old female Shih-tzu, with no previous signs of respiratory or cardiovascular disease, who died a few hours after bathing in a pet shop, with symptoms of stress and acute respiratory failure and with necroscopic changes compatible with hemorrhage and pulmonar edema, without signs of cranial trauma or trauma in other organs. The importance of minimizing stress in grooming procedures is emphasized, in order to avoid these acidentes, as well as the presence of the veterinarian responsible for the establishment, so that appropriate and early measures can be taken to prevent these potentially fatal conditions.

The students following Engineering disciplines should acquire a conceptual understanding of the concepts and the processors and attitudes. There are two recognizable learning environments for students: classroom and laboratory environments. With the COVID-19 Pandemic, both environments merged to online environments, impacting students' processes and characteristic attitudes development. This paper introduces a theoretical framework based on experiential learning to plan and deliver processes online. A case study based on the power-factor correction experiment was presented. The traditional experiment that runs for 2 hours was broken into smaller tasks such as pre-lab activity, simulation exercise, PowerPoint presentation, remote laboratory activity, and final report based on the experiential learning approach. The delivery of the lab under online mode delivery was presented. Then students' performance was compared before and after the online mode of delivery. It was found that students' performance on average has a distinct improvement. In order to obtain students' reflections about the online experiential learning approach, a questionnaire that carries close and open-ended questions was administered. The majority of the students liked the approach followed and praised for allowing them to experiment in a novel way during the COVID-19.

La investigación pretende describir la perspectiva de los estudiantes de la Licenciatura en Educación Primaria ante la educación virtual en tiempos de pandemia, se da respuesta a las preguntas de investigación sobre cuál es su concepto de educación virtual y qué características debe cumplir esta. Se realiza una investigación cualitativa, con diseño narrativo y alcance descriptivo, el análisis de los datos se hace con el software Atlas.Ti. Los resultados obtenidos indican que los estudiantes consideran este período de trabajo virtual muy estresante, por factores, como la comunicación y la dificultad en la conectividad y acceso a equipos tecnológicos. Se concluye que la educación virtual en su mayoría tiene que ver con generación de estrés por desconocimiento, es decir, a pesar de ellos ya tenían la experiencia con cursos virtuales, no fue lo mismo al trasladarlos todos a la misma modalidad.

Abstract

The present research describes the perspective of students enrolled in the Bachelor's Degree Program in Primary Education (LEIPURI-Licenciatura en Educación Primaria) on virtual education in times of pandemic. It answers research questions about what their concept of virtual education is and what are the characteristics it should fulfill. Qualitative research is carried out, with a narrative design and descriptive scope; the data analysis is done with the Atlas.ti software. The results obtained indicate that students rate this period of virtual work as being very stressful, due to factors such as communication, and the difficulty in connectivity and lack of availability of technological equipment. It is concluded that virtual education, for a significant part of the sample, is related to the development of stress due to lack of knowledge, that is to say, despite the fact that the students already had experience with virtual courses, there is no comparison when transferring them all to the same modality.
