Authors: Minh Nguyễn Phước
Published: July 2021

Vietnam is one of the leading rice export countries in the world. ST25 fragrant rice (Oryza sativa L.) won the top prize for best rice in the world in 2019 and the second at World's Best Rice Contest 2020. Plasma has been considered as an innovative food processing technology. The aim of this study demonstrated the impact of time (4, 6, 8, 10, 12 min), power (160, 180, 200, 220, 240 W) and oxygen flow rate (0.2, 0.4, 0.6, 0.8, 1.0 ml/min) to the physicochemical and functional qualities of ST25 fragrant rice flour. Results showed that under plasma treatment time at 10 minutes, power 200 W, oxygen flow rate 0.8 ml/min, the amylose content (16.67±0.01 %), pasting temperature (83.21±0.02 oC), water absorption index (14.54±0.00 gm/gm sample), water solubility index (10.31±0.02 gm/100 gm sample), swelling power (14.96±0.00 gm/gm sample) were recorded. Under plasma treatment, surface of the ST25 fragrant rice flour became more hydrophilic to absorb more water resulting to shorter cooking time. Plasma treatment provides environmentally friendly processing of rice grain to limit pesticide abuse towards ecological farming.
Regulacyjna funkcja intuicji językowej w rozwijaniu podsystemu leksykalno-semantycznego: test wnioskowania znaczeń w limitowanym czasie
Authors: Piegzik Wioletta A.
Published: July 2021

The paper emphasizes the role of linguistic intuition in current L2 processing. Intuition, as a mental disposition operating in implicit systems, is in close correlation with working memory. It infers quick, almost immediate meaning of un unknown word which appears in a context. Linguistic intuition has a regulatory function, i.e. it allows to continue language activities and overcome linguistic deficits. In the second part, Timed inference test as a tool for developing and testing vocabulary is proposed as well as the results of the empirical study on intuitive behaviour in L2. The results of the study show that inference of word’s meaning under time constraint is lower that the results of inference without time pressure. The study involves a group of 102 students of French as a foreign language at B1 level.
Rozwijanie sprawności pisania obcojęzycznego na przykładzie polsko-niemieckiego internetowego projektu tandemowo-tridemowego „Schreiben(üben) im e-Tandem/e-Tridem” – możliwości i ograniczenia
Authors: Pawłowska-Balcerska Agnieszka
Published: July 2021

Although in the age of media writing is experiencing a kind of renaissance, and young people cannot imagine everyday life without texts, e-mails, online discussion forums or virtual instant messaging, writing as part of institutionalized teaching evokes rather negative associations among many learners. Therefore, based on the example of the Polish-German online tandem-tridem project, an attempt will be made in this article to answer the following questions: How can one draw on the positive, out-of-school experiences of learners with (foreign) writing in foreign language classes? How can they be used in the institutionalized process of teaching and learning foreign languages while developing writing skills? What advantages and dangers are associated with the mentioned activities?
TED talks as resources for the development of listening, speaking and interaction skills in teaching EFL to university students
Authors: Kozińska Katarzyna
Published: July 2021

The article presents a study conducted on 27 university students and 5 of their teachers in the Winter semester 2020/21. The study was conducted because of recommended online teaching at Polish universities and almost four decades after the first TED event, when the TED community has become worldwide and the recordings of the events can be accessed online cost-free by anybody. The popularity of TEDs and the need to teach online prompted the author to incorporate it in teaching practice and review research literature from the areas of SLA (Second Language Acquisition), EFL (English as a Foreign Language) teaching and learning, socio-constructivism and adult learning. Based on this review, a hypothesis was formulated: TED talks support the development of listening, speaking, and interaction skills when used as a supplementary resource in teaching English as a foreign language to university students. Three supplementary questions were formed to test the hypothesis. Data was obtained in an online questionnaire and analysed using the qualitative data analysis framework of Miles and Huberman (1994). The study confirmed the hypothesis. Lessons with TEDs are valued as varied, interesting, inspiring and supporting oral communication skills’ development. Results are discussed, conclusions drawn and further research explored.
The influence of foreign languages on L1: the case of intervocalic stop occlusion
Authors: Sypiańska Jolanta
Published: July 2021

The aim of the article is to investigate cross-linguistic influence (CLI) of foreign languages on the L1 also referred to as L1 drift. The influence is measured by means of the degree of intervocalic stop occlusion in all the languages of L1 Polish, L2 Spanish and L3 English multilinguals. Although Polish is a language with no systemic spirantization of intervocalic stops, the assumption is that if L1 Polish is under the influence of L2 Spanish in multilinguals the degree of intervocalic stop occlusion may be lower in the otherwise non-spirantized context in L1 Polish. The degree of intervocalic stop occlusion is calculated with measures of intensity: Cmin, Vmax; but also with measures of relative intensity used in spirantization research: IntDiff and IntRatio. The results show that only Cmin and Vmax effectively capture the influence of L2 on L1, whereas the extent of the influence is conditioned by how well the speakers master spirantization in their L2 Spanish. Finally, as predicted, the L3 does not constitute a source of influence for the L1.
Modalizatory jako wielowymiarowe zagadnienie w nauce języka szwedzkiego
Authors: Kowal Iwona
Published: July 2021

Sentence adverbials build a multidimensional constituent in many languages, i.e. they can, among others, modify the meaning of the entire sentence, emphasize a particular element in it, or build the coherence in texts. Due to the multifaced character of this linguistic phenomenon the acquisition of it in foreign language learners can be a complex process. The learner is not only faced with a variety of different words and phrases that can be used in order to deliver a complementary information in the text, but also, depending on the structural requirements of the specific language, has to learn to put this constituent in the correct place in the sentence. In present paper the use of sentence adverbials in Polish learners od Swedish will be presented. The data considered in the analysis comprises two types of texts: a summary of an expository text and a narrative. The results show that foreign language learners at the intermediate stage of the language use a broad repertoire of sentence adverbials and place them in appropriate contexts. In narratives modal expressions predominate, while in summaries connectives and intensifiers are used more often. The learners can place sentence adverbials correctly in the sentence, especially in main clauses. However, the word order in dependent clauses when other sentence adverbials occur, except for sentences with the negation inte, is still under development.
A direct measure of subjective business uncertainty
Authors: Glocker Christian , Hölzl Werner
Published: July 2021

We present an uncertainty measure that is based on a business survey in which uncertainty is captured directly by a qualitative question on subjective uncertainty regarding expectations. Uncertainty perceptions display persistence at the firm level and changes are associated with past business assessments and expectations. While our uncertainty measure correlates with commonly used alternatives, it is superior in forecasting and suggests a larger role of uncertainty shocks for aggregate fluctuations. Its informational content is highest when considering smaller firms or firms with a low growth rate. Our results confirm the feasibility of constructing uncertainty measures from business survey questions that elicit information on uncertainty of respondents directly.
Datenqualität und -kuratierung als Voraussetzung für Open Research Data
Authors: Azeroual Otmane
Published: July 2021

Die Bedeutung von Daten für Gesellschaft und Wirtschaft kann nicht überschätzt werden und nimmt im Zuge von Digitalisierung weiter zu. Die Nachnutzung vorhandener Daten bietet erhebliche Vorteile auf wissenschaftlicher, politischer, sozialer, kultureller und insbesondere wirtschaftlicher Ebene. Die Öffnung von Datensammlungen (Open Data) stößt sowohl im öffentlichen als auch im privaten Sektor auf gesteigertes Interesse. Dies geht auf die Bemühungen zur vermehrten Transparenz im öffentlichen Sektor und auf die Begeisterung für Big Data und Datenanalyse zurück. In den letzten Jahren haben daher immer mehr Ministerien bzw. Regierungen begonnen, ihre Daten zu veröffentlichen. Diese sogenannten Open Government- oder Open Research-Bewegungen haben zur Einführung zahlreicher Portale geführt, die eine Infrastruktur für den Zugang zu Forschungsdaten bereitstellen. Die Entwicklung dieser Infrastruktur verändert die Art, wie Forschende nach Daten zur Beschreibung ihres Forschungsgegenstandes oder nach analysierbaren Forschungsdaten suchen. Implizit geht es vor allem darum, mehr Datenaustausch und Transparenz zu erreichen, um die Öffnung weiterer Datensilos für breite Anwenderkreise voranzutreiben. Qualitätsfragen spielten dabei in der Anfangsphase eine zu geringe Rolle. Dieser Beitrag will darauf aufmerksam machen, wie Datenqualitätskriterien sowohl für die Quelldaten als auch die Metadaten Infrastrukturen optimieren können.

Authors: Demir Funda , Ozen Meral Yildirim , Derun Emek Moroydor
Published: July 2021

In this study, essential (Ca, Cr, Cu, Fe, K, Mg, Na, P, Zn), and non-essential (Al, Ni, Pb) element contents of the drinking and baby water samples which are sold in the local market and tap water samples in Istanbul were examined. It was determined that elements of Cr, Cu, Fe, P, Zn, Al, and Ni were below detection limits in all water samples. Among the non-essential elements analyzed in water samples, Pb was the only detected element.

At the same time, the percentages that meet the daily element requirements of infants were also calculated. As a result of the evaluations made, there is no significant difference in infant nutrition between baby waters and other drinking waters in terms of the element content.
Filling the Void in Archaeological Excavations: 2D Point Clouds to 3D Volumes
Authors: Nobles Gary R. , Roosevelt Christopher H.
Published: July 2021

3D data captured from archaeological excavations are frequently left to speak for themselves. 3D models of objects are uploaded to online viewing platforms, the tops or bottoms of surfaces are visualised in 2.5D, or both are reduced to 2D representations. Representations of excavation units, in particular, often remain incompletely processed as raw surface outputs, unable to be considered individual entities that represent the individual, volumetric units of excavation. Visualisations of such surfaces, whether as point clouds or meshes, are commonly viewed as an end result in and of themselves, when they could be considered the beginning of a fully volumetric way of recording and understanding the 3D archaeological record. In describing the creation of an archaeologically focused recording routine and a 3D-focused data processing workflow, this article provides the means to fill the void between excavation-unit surfaces, thereby producing an individual volumetric entity that corresponds to each excavation unit. Drawing on datasets from the Kaymakçı Archaeological Project (KAP) in western Turkey, the article shows the potential for programmatic creation of volumetric contextual units from 2D point cloud datasets, opening a world of possibilities and challenges for the development of a truly 3D archaeological practice.
Highly conjugated carbazole-based monomers for the control of nanotubular surface structures by soft template electropolymerization
Authors: Fradin Caroline , Guittard Frédéric , Darmanin Thierry
Published: July 2021

In this work, a bioinspired approach is used to prepare nanotubular structures with tunable hydrophobicity and water adhesion by a soft template surfactant-free electropolymerization in organic solvent. Various highly conjugated carbazole-based molecules are used as monomer. The presence of water in the organic solvent enables the formation of porous and rough nanostructures. Their shapes depend essentially on the nature of the monomer and the way it polymerizes. Various morphologies were obtained from nanoparticles network to horizontally or vertically aligned nanotubes. The nanostructured surfaces reach superhydrophobic properties and their dynamical behavior varies with the monomer from sticky to slippery. For example, using 9,3′:6′,9″-tercarbazole (TC) very long nanotubes are observed but their number is higher at constant potential. At high deposition charge, it is observed that most of the tubes are even collapsed leading to a strong increase of surface hydrophobicity with apparent contact angle up to 143° with strong water adhesion comparable to rose petals or gecko foot.

Tempolimit 130 auf Autobahnen: Eine evidenzbasierte Diskussion der Auswirkungen
Authors: Bauernschuster Stefan , Traxler Christian
Published: July 2021

Welche Effekte würde ein allgemeines Tempolimit auf deutschen Autobahnen mit sich bringen? Stefan Bauernschuster und Christian Traxler versuchen, sich dieser oft emotional diskutierten Frage empirisch zu nähern. Die Autoren stoßen dabei rasch an Grenzen: Die Datenlage ist dürftig und kausale Evidenz ist rar. Gleichwohl skizzieren sie in ihrem Beitrag auf Basis der vorhandenen Daten und der internationalen Literatur eine Einschätzung, wie sich die Einführung eines Tempolimits 130 unter anderem auf Verkehrssicherheit, Emissionen und Zeitverluste auswirkt. Vieles spricht dafür, dass der Nutzen eines Tempolimits die möglichen Kosten übersteigt. Die Autoren rufen zu einer Stärkung der evidenzbasierten Verkehrspolitik auf.

Authors: Tyagunova Tanya
Published: July 2021

Dieser Beitrag fokussiert die universitäre mündliche Prüfung als spezifische kommunikative Praxis. Seinen Ausgangspunkt bildet die Beobachtung, dass sich die Situation eines Prüfungsgesprächs für Prüflinge vor allem als Problem der Formulierung einer angemessenen Antwort unter den Bedingungen der doppelten Offenheit der Prüfungskommunikation konstituiert: der Offenheit der Antwortevaluation und der Unsicherheit bezüglich der Kriterien der Antwortangemessenheit. Der Beitrag verfolgt das Ziel, empirisch zu rekonstruieren, wie dieses Problem von den Prüflingen bearbeitet wird. Anhand der Analyse von Interaktionssequenzen aus mündlichen Prüfungen in den modularisierten Lehramtsstudiengängen wird gezeigt, wie Prüflinge mit der Aufforderung zur Verbalisierung ihres Wissens situativ umgehen. Die rekonstruierten Techniken können als verfahrensbegrenzte regulative Mechanismen verstanden werden, sich als wissend und diskursfähig darzustellen. Sie stellen den Ausdruck einer praxisinternen Verfahrenskompetenz dar.

Authors: Guryeva Alla B. , Alekseyeva Vilyuia A.
Published: July 2021

Objective — Investigating the features of blood biochemical parameters in patients with type 2 diabetes mellitus (DM2), depending on the somatotype sensu the Rees-Eysenck body index. Material and methods — We examined 88 women of Yakut nationality (39-74 years old) with an established diagnosis of DM2. An anthropometric examination with consequent somatotyping according to the Rees-Eysenck body index, along with determination of BMI were carried out. The biochemical blood test results were copied from the anamneses of female subjects. Statistical analysis was performed using the SPSS Statistics software package for Windows (version 17). Methods of parametric and nonparametric statistics were used. Results — We established that the anthropometric parameters and BMI of women with DM2 were significantly higher. According to the BMI gradation, obesity was more common in people with DM2. The results of somatotyping implied that 11.4%, 50.0% and 38.6%of the examined women belonged to the asthenic, normosthenic and pyknic somatotypes, correspondingly. The distribution of somatotypes among women with DM2 differed from the general population distribution in a smaller fraction of individuals with asthenic somatotype. Blood biochemical parameters in subjects with asthenic body type were within the reference limits (except for glucose), in contrast to those of women with other somatotypes. Conclusion — Women with asthenic somatotype are less at risk of developing DM2. Even if the ailment develops, their blood biochemical parameters remain within reference limits, with the exception of glucose.

Authors: Novozhilova Nina E. , Pianzina Anna V. , Korol Victoria A.
Published: July 2021

This article reviews the most common oral health problems, which could be associated with coronavirus disease 2019 (COVID-19). Several reports were published, which described various oral manifestations of COVID, including dysgeusia, petechiae, candidiasis, traumatic ulcers, herpesvirus infection, geographic tongue, thrush like ulcers, among others. Alterations of smell and taste seem to be the most common manifestations of COVID in the orofacial area, which could be directly related to the effect of the virus. Other oral conditions seem to be secondary to the decrease of host defense, or else caused by the drugs and intensive care used in the treatment of COVID-19.

Authors: Altukhova Aljona V. , Kaurkin Sergey N. , Skvortsov Dmitry V. , Akhpashev Alexander A. , Zagorodniy Nikolay V.
Published: July 2021

The goal of this research was to investigate functional and biomechanical symptoms in patients with chondromalacia patella. Material and Methods — Gait biomechanics was assessed in 35 patients with diagnosed unilateral chondromalacia patella and in 20 healthy adult controls. We recorded hip and knee movements, impact loads and temporal characteristics of the gait cycle (GC) during self-paced walking. Results — The temporal characteristics of gait and the impact loads remained normal in the patient population. Hip flexion amplitude decreased both on the affected (p=0.002) vs. unaffected (p=0.016) sides, compared to healthy control, whereas the amplitude phase increased on the affected (p=0.012) vs. unaffected (p=0.001) sides, versus healthy control. Hip extension and adduction-abduction amplitudes did not change significantly. Stance-phase and swing-phase knee flexion amplitudes did not change significantly. Knee extension amplitude on the affected limb increased (p=0.015), and knee rotation on the unaffected limb decreased versus control (p=0.016). The so-called stairstep symptom defined in the study was found in 83% of patients: in 23 patients bilaterally and in 6 patients unilaterally. Conclusion — Chondromalacia patella affected the gait biomechanics on both sides. The changes in the kinematic patterns during the flat-surface walking were not substantial. The only pathognomonic functional symptom of the condition was the stairstep symptom.
The Holy Family as a Model of the Spiritual Life in Bl. Bolesława Lament’s Teaching
Authors:   Cardinal Stefan Wyszynski University, Korbut Ewa
Published: July 2021

The Christian spiritual life, the essence of which is holiness, needs an example that sheds clear light on the path of love for God and neighbor. In her teachings, Bl. Bolesława Lament indicates that the example of the Holy Family of Nazareth’s life is especially helpful in for man’s spiritual development. The Holy Family’s example can help shape the spiritual life of believers according to the Incarnation. The essence of the Holy Family’s example is its deep focus on the mystery of Incarnation and, thus, union with Christ, the Incarnate Word. Moreover, the hidden life of Jesus, Mary, and Joseph provides a solid foundation on which apostolic life can take on form.
Baptism as the Beginning of the Path to Moral Perfection in One’s Personal and Social Life
Authors:   John Paul II Catholic University of Lublin, Zadykowicz Tadeusz
Published: July 2021

The Christian moral life can be compared to a path marked out by particular stages. The beginning of this path is no less important than its end, which is perfection in the temporal dimension and salvation in the ultimate spiritual dimension. Contrary to popular opinion, the beginning of the path is not associated with an individual’s personal desire to be perfect; rather, it is a gift from God, who accompanies man throughout his entire life and needs his free response. Among the many gifts that God imparts to man, man receives essential gifts in the sacrament of Baptism. These gifts constitute the subject of moral action itself; they interiorly form man without determining his actions absolutely or depriving him of his freedom. A “new,” free, and responsible action, the fruit of which is man’s perfection as an individual and as a member of a natural and supernatural society, flows from this interior transformation. The basic character of the gifts of the sacrament of Baptism is that they are the source itself of a specifically Christian morality and not just an ordinary aid in the moral life.

Published: July 2021

After the Second Vatican Council, the Church in Białystok became open to the catechetical trend of kerygmatic renewal. Influenced by Her predecessors, the Church began to move away from didactic catechesis and to developing a catechesis based on initiation. Drawing on years of pastoral experience, the Archdiocese of Białystok implemented its own catechetical program that includes scripts and teaching aids based on a catechumenal model of formation to prepare children to receive the Sacraments of Reconciliation and the Eucharist.
Bisphosphonates after denosumab withdrawal reduce the vertebral fractures incidence
Authors: Grassi Giorgia , Chiodini Iacopo , Palmieri Serena , Cairoli Elisa , Arosio Maura , Eller-Vainicher Cristina
Published: July 2021

Objective

Several studies showed the occurrence of vertebral fracture (VFx) in patients discontinuing denosumab (Dmab), suggesting the need of bisphosphonate (BPs) therapy to mitigate this VFx risk increase. However, the morphometric VFx (morphoVFx) incidence after Dmab discontinuation and the BPs effect on VFx risk in this setting are still a matter of debate.

Design

Retrospective, monocentric study.

Methods

In 120 patients (111 females) discontinuing Dmab, 19 have not been treated (non-treated group: 16 females, aged 63.5 ± 15.0 years) and 101 patients have been treated (treated group: 95 females, aged 70.0 ± 10.6 years) with BPs (28 alendronate (ALN); 73 zoledronate ZOL), single infusion), respectively. We evaluated the incidence of both clinical VFx and morphoVFx in treated group and non-treated group.

Results

Patients in treated group showed a 5.5% VFx incidence (n = 6, three clinical, three morpho VFx), which was anyway lower than non-treated group patients (n = 4, 21.1%, four clinical, three multiple, P = 0.029), despite a comparable FRAX score at the time of Dmab initiation. The logistic regression analysis showed that the VFx incidence was independently associated with the lack of BPs treatment (odds ratio: 13.9, 95% CI 1.7–111.1, P = 0.014), but not with the number of Dmab injections, age, duration of BPs before Dmab initiation, the BMD at Dmab withdrawal, and the prevalence of VFx at Dmab withdrawal.

Conclusions

The Dmab withdrawal is associated with an increased risk of clinical but not morphometric VFx. Therapy with ALN or with a single ZOL treatment is partially effective in reducing the increased VFx risk after Dmab withdrawal.

Aim

The risk of differentiated thyroid cancer (DTC) recurrence is widely evaluated according to the 2015 ATA Risk Stratification System. Topography of malignant nodules has been previously reported as an additional risk factor but is not included in the ATA system. Thus, our study aimed to evaluate the relationship between DTC topography and response to initial therapy.

Patients and methods:

We enrolled 401 low- to intermediate-risk patients with DTC who had undergone thyroidectomy and radioiodine therapy. DTC topography was recorded and compared with the response to therapy as assessed 12 months after the end of therapy.

Results

Overall, 366/401 (91.3%) patients had an excellent response to initial therapy while 22/401 (5.5%) and 13/401 (3.2%) had incomplete biochemical or structural responses, respectively. Incomplete response occurred in 10/36 (27.8%), 5/125 (4.0%), and 4/111 (3.6%) patients whose unifocal malignant nodules were located in the isthmus, right lobe, or left lobe. Incomplete response was also observed in 4/54 (7.4%) and 12/75 (16%) patients carrying multifocal cancers in one or both lobes, respectively. Patients with isthmic cancer more frequently demonstrated incomplete response compared with those who had cancer in other locations (P = 0.00). No significant relationship was found with age, gender, maximum size of malignant nodule, Hashimoto’s thyroiditis, vascular invasion, and extrathyroidal extension (P = 0.78, P = 0.77, P = 0.52, P = 0.19, P = 0.73, and P = 0.26, respectively). The risk of incomplete response was about 65% higher in patients with isthmic lesions compared with other patients (odds ratio = 6.725). A log-rank test demonstrated that disease-free survival (DFS) of patients with isthmic lesions was significantly shorter than that of other patients (P = 0.02).

Conclusion

Our data show that isthmus topography of malignant thyroid nodules is a risk factor for having both persistent disease 12 months after primary treatment and reduced DFS.

Published: July 2021

Cellulose materials and related bioresources have been the first-line tools of defense of human health against COVID-19. The alfa cellulose, wood cellulose, and multilayer composite face masks have been used by billions, simultaneously with millions of tons of cellulosic bioresources-based medical specialty, hygiene, and packaging products used to deal with the global disaster. This editorial considers recently available facts and disputes some statements that have appeared in the media during the year 2020 concerning properties and the risks of the masks. According to recent findings, the carbon dioxide concentration increases by 2.3 to 4.3 times inside of the mask, compared to ambient air, and therefore we suppose that there will be also a concentration increase of larger chemical compounds, toxins, volatile organic compounds (VOC), and particles. These quantities should be measured, and the data used in further research aimed at quality improvement.
Catalytic condensation of depithed sugarcane bagasse derived levulinic acid into diphenolic acid
Authors: Mthembu Lethiwe Debra , Lokhat David , Deenadayalu Nirmala
Published: July 2021

Levulinic acid (LA) is a platform chemical that can be produced from biomass. Diphenolic acid (DPA) is a derivative of LA with the potential to replace bisphenol A, a plasticizer. To determine the optimum conditions for DPA production, commercial LA was used with a mild environmentally benign acid, namely, methanesulfonic acid (MsOH). The optimized reaction parameters were time (6 h), temperature (75 °C), and catalyst loading (5.5 g), yielding 65.8% DPA at 90% LA conversion. The response surface methodology (RSM) study indicated that the temperature had the most significant effect on DPA yield, followed by time and catalyst loading. The analysis of variance (ANOVA) revealed that the model was able to satisfactorily predict the DPA yield. To determine the effect of catalyst on DPA production from commercial LA, ionic liquids (ILs), MsOH, and sulfuric acid were used. IL catalysts produced 59 to 68% of DPA, MsOH produced 65.6% of DPA, and sulfuric acid produced the maximum DPA of 74%. The study of LA: phenol ratio revealed that more reactants (2:5) yielded the most DPA (86.35%). The optimized reaction conditions were then used to produce DPA from LA derived from depithed sugarcane bagasse (DSB), which yielded 64.5% of DPA.
Educación política para una democracia radical
Authors: Sant Edda
Published: July 2021

Este artículo parte del argumento, la democracia liberal está en crisis. Partiendo de un análisis sistemático de la literatura, se identifican modelos alternativos que podrían remplazar este tipo de democracia hasta ahora hegemónico. A continuación, se hace una propuesta para una educación política alineada con la democracia radical que plantean Ernesto Laclau y Chantal Mouffe. Se entiende que el objetivo de la educación democrática radical y política debe facilitar que el alumnado pueda abrir, expandir y cambiar el proyecto democrático. Para ello, se propone tres pedagogías: pedagogías para la diferencia, para la articulación y para la equivalencia que, desde este punto de vista, pueden contribuir a este objetivo. Se termina el artículo presentando ejemplos de cómo estas pedagogías se podrían llevar a la práctica basados en las investigaciones cualitativas recientes de la autora Edda Sant.

Evaluación de algunos factores de riesgo para la presentación de síndrome de úlcera gástrica (SUGE) en el caballo criollo colombiano en el Valle de Aburrá, Antioquia (Colombia)
Authors: Gómez Felipe , Ruiz Jhon Didier , Balvin Dubel
Published: July 2021

Las úlceras gástricas se definen como la pérdida de continuidad de la mucosa gástrica. Se originan principalmente por desequilibrio entre factores injuriantes y de protección del estómago. Generalmente se manifiestan con signos como pérdida de peso, cólico, bruxismo e inapetencia, conllevando al bajo rendimiento del animal y pérdidas económicas. El objetivo del presente estudio fue determinar la prevalencia y factores de riesgo para la presentación de SUGE en CCC del Valle de Aburra. Se realizó gastroscopia a 100 animales de diferentes pesebreras, entre dos y 25 años de edad; cada estómago se caracterizó macro y microscópicamente. Las lesiones macroscópicas se valoraron de acuerdo con el grado de lesión según el Equine Gastric Ulcer Council, y la clasificación microscopica se basó en una adaptación hecha por patrones de descripción de lesiones más utilizados como: The sidney system y Equine gastritis grading system (EGGS). Para el análisis de los resultados, se tuvieron en cuenta variables como la intensidad del ejercicio, alojamiento, tipo y frecuencia de alimentación, transporte y frecuencia del mismo. El 65% de los equinos evaluados presentaron lesiones compatibles con SUGE. Macroscópicamente el grado 2 de severidad fue el más común (38%), con mayor presentación en la región aglandular. Microscópicamente el edema en la región fundica y pilórica fue la lesión más frecuente (35,2% y 30,7%, respectivamente). Los principales factores de riesgo asociados a la presentación de las lesiones fueron el transporte de los animales y la intensidad del ejercicio.

Bromatological parameters in 39 Warakú verdadero (Leporinus agassizi) and 21 Warakú pinima (Leporinus fasciatus) fillets were analyzed at three different sites of the Vaupés River, Colombia sampled during a hydrobiological cycle. The bromatological parameters did not shown significant differences in relation to the sites and season of capture. At point 3 and during the descending water season, Leporinus agassizi had the highest values for dry matter (25.24%), protein (19.82%) and ash (2.16%). The highest lipid value for this species was found in low waters at point 1 (2.93%). Leporinus fasciatus showed the highest levels of dry matter (25.19%) and ash (2.16%) at point 3 during ascendant and high waters, respectively. The bromatological parameters tends to vary regarding the time of year. It was possible to determined that these fish species have great potential for continental aquaculture thus constituting a healthy food model.

The first case of gynandromorphy in Centris pallida (Hymenoptera: Apidae: Centridini)
Authors: Barrett Meghan
Published: July 2021

A case of gynandromorphy is reported for the first time for Centris pallida Fox, a bee species found predominantly in the deserts of the southwestern United States and northern Mexico. This specimen marks only the second report of a gynandromorph within the tribe of oil-collecting bees, Centridini, and the first Centris Fabricius. The specimen exhibits mosaic gynandromorphy, with male and female characteristics randomly distributed throughout the body. Males of C. pallida are morphologically and behaviorally dimorphic (a large and a small male morph), and the male characteristics of the gynandromorph are more similar to the large male morph, which is also most similar in head width to the specimen.

El motor de combustión interna de encendido provocado es una máquina térmica que permite obtener una potencia mecánica a partir de la energía química de un combustible. El presente trabajo tuvo como objetivo evaluar el desempeño de un motor de combustión interna mediante el balance de energía y exergía, bajo el uso individual de las tres gasolinas comercializadas en el Ecuador (súper, extra y ecopaís). La metodología experimental consistió en la puesta en marcha bajo el uso individual de las gasolinas hasta alcanzar su máxima potencia a una velocidad de giro del motor, donde se tomaron mediciones de temperatura, consumo específico del combustible y la relación aire combustible para un tiempo de tres minutos. Los resultados muestran una eficiencia energética de 11,31 % para gasolina súper, 10,75 % para gasolina extra y 10,39 % para gasolina ecopaís. En lo relacionado a la eficiencia exergética se estableció un 58,81 % para la gasolina súper, 58,89 % para la gasolina extra y un 59,19 % para la gasolina ecopaís. Los resultados permiten concluir que existe un potencial exergético de mejoramiento que puede ser una oportunidad para aumentar la eficiencia energética.

Purpose: This retrospective study investigated the feasibility, diagnostic, and therapeutic advantages of the gastrografin challenge on patients with adhesive small bowel obstruction (ASBO). Methods: There were 125 patients reviewed who were admitted to the Department of General Surgery at a single institution (September 2018 to August 2019) with a diagnosis related to ASBO. The study population included 100 patients (114 cases) who had received initial conservative management. Patient characteristics and operation rates were compared between the gastrografin challenge success group and failure group, and operation rates and length of hospital stay were compared between the gastrografin challenge group and “non-challenge” group. Results: During the study period, 21 patients with ASBO underwent the gastrografin challenge. The challenge was successful in 17 patients where the bowel obstruction was resolved without the need for surgery. Among patients who failed the challenge, 2 patients underwent adhesiolysis and 2 patients were able to progress their diet avoiding surgery. In patients who underwent surgery (n = 2), the length of hospital stay was significantly shorter in the gastrografin challenge group compared with the “non-challenge” group sub analysis (n = 13 cases; 10.5 vs. 20 days, p = 0.038), indicating that the gastrografin challenge assisted rapid decision-making for surgery. No adverse events were reported for the 21 gastrografin challenges. Conclusion: In patients with ASBO, the gastrografin challenge is an accurate, safe method to determine the need for surgery. In addition, the gastrografin challenge may reduce the length of stay in patients who required surgery for ASBO resolution.
Case Report of a Laparoscopic Primary Diaphragmatic Repair in Acute Penetrating Trauma: Is It Within the Realm of an Acute Care Surgeon?
Authors: Pillay Yagan , Vetter Cheyenne
Published: July 2021

The laparoscopic repair of traumatic diaphragmatic injuries in the acute phase has not been well established. The current consensus view is an elective repair by a surgeon with an advanced laparoscopic skill set. This case report illustrates the position that with judicious patient selection an acute repair is not only possible but well within the realm of an acute care surgeon. Anterior diaphragmatic injuries with penetrating trauma can even be repaired primarily without the need for prosthetic reinforcement. It is hoped that this case report will add to the surgical armamentarium of the acute care surgeon.
