Authors: Zhong Tao , Zhuang Zian , Dong Xiaoli , Wong Ka Hing , Wong Wing Tak , Wang Jian , He Daihai , Liu Shengyuan
Published: July 2021

BACKGROUND

Tuberculosis (TB) is a pandemic, being one of the top 10 causes of death and the main cause of death from a single source of infection. Drug-induced liver injury (DILI) is the most common and serious side effect during the treatment of TB.

OBJECTIVE

We aim to predict the status of liver injury in patients with TB at the clinical treatment stage.

METHODS

We designed an interpretable prediction model based on the XGBoost algorithm and identified the most robust and meaningful predictors of the risk of TB-DILI on the basis of clinical data extracted from the Hospital Information System of Shenzhen Nanshan Center for Chronic Disease Control from 2014 to 2019.

RESULTS

In total, 757 patients were included, and 287 (38%) had developed TB-DILI. Based on values of relative importance and area under the receiver operating characteristic curve, machine learning tools selected patients’ most recent alanine transaminase levels, average rate of change of patients’ last 2 measures of alanine transaminase levels, cumulative dose of pyrazinamide, and cumulative dose of ethambutol as the best predictors for assessing the risk of TB-DILI. In the validation data set, the model had a precision of 90%, recall of 74%, classification accuracy of 76%, and balanced error rate of 77% in predicting cases of TB-DILI. The area under the receiver operating characteristic curve score upon 10-fold cross-validation was 0.912 (95% CI 0.890-0.935). In addition, the model provided warnings of high risk for patients in advance of DILI onset for a median of 15 (IQR 7.3-27.5) days.

CONCLUSIONS

Our model shows high accuracy and interpretability in predicting cases of TB-DILI, which can provide useful information to clinicians to adjust the medication regimen and avoid more serious liver injury in patients.
Metadata Correction: “Desensitization to Fear-Inducing COVID-19 Health News on Twitter: Observational Study” (Preprint)
Authors: Stevens Hannah R , Oh Yoo Jung , Taylor Laramie D
Published: July 2021

BACKGROUND

As of May 9, 2021, the United States had 32.7 million confirmed cases of COVID-19 (20.7% of confirmed cases worldwide) and 580,000 deaths (17.7% of deaths worldwide). Early on in the pandemic, widespread social, financial, and mental insecurities led to extreme and irrational coping behaviors, such as panic buying. However, despite the consistent spread of COVID-19 transmission, the public began to violate public safety measures as the pandemic got worse.

OBJECTIVE

In this work, we examine the effect of fear-inducing news articles on people’s expression of anxiety on Twitter. Additionally, we investigate desensitization to fear-inducing health news over time, despite the steadily rising COVID-19 death toll.

METHODS

This study examined the anxiety levels in news articles (n=1465) and corresponding user tweets containing “COVID,” “COVID-19,” “pandemic,” and “coronavirus” over 11 months, then correlated that information with the death toll of COVID-19 in the United States.

RESULTS

Overall, tweets that shared links to anxious articles were more likely to be anxious (odds ratio [OR] 2.65, 95% CI 1.58-4.43, P<.001). These odds decreased (OR 0.41, 95% CI 0.2-0.83, P=.01) when the death toll reached the third quartile and fourth quartile (OR 0.42, 95% CI 0.21-0.85, P=.01). However, user tweet anxiety rose rapidly with articles when the death toll was low and then decreased in the third quartile of deaths (OR 0.61, 95% CI 0.37-1.01, P=.06). As predicted, in addition to the increasing death toll being matched by a lower level of article anxiety, the extent to which article anxiety elicited user tweet anxiety decreased when the death count reached the second quartile.

CONCLUSIONS

The level of anxiety in users’ tweets increased sharply in response to article anxiety early on in the COVID-19 pandemic, but as the casualty count climbed, news articles seemingly lost their ability to elicit anxiety among readers. Desensitization offers an explanation for why the increased threat is not eliciting widespread behavioral compliance with guidance from public health officials. This work investigated how individuals' emotional reactions to news of the COVID-19 pandemic manifest as the death toll increases. Findings suggest individuals became desensitized to the increased COVID-19 threat and their emotional responses were blunted over time.

Hemp! Thread, cloth and a calendar
Authors: Boertien Jeannette
Published: July 2021

Hemp cultivation and hempen cloth is the main theme of this paper. Iron Age textile fragments from the Southern Levant indicate that most textiles were made of some kind of plant fiber. Traditionally this region was regarded as linen territory, and indeed most textile finds were registered as such. The difference between linen and hemp is difficult to tell even with a regular microscope. But when using a scanning electron microscope, the difference becomes visible. This technique sheds new light on the use of bast fibers in the region. A piece of fabric from Tell Deir Alla in the Jordan Valley was the first item that could be registered as hempen cloth from the Southern Levant. The textile fragment was found amidst the loom weights of the loom on which it was woven, which raises new questions. Was the textile made of local hemp grown in the Jordan Valley? To answer this question, the cultivation of hemp will be discussed in relation to soil and climatic conditions of the central Jordan Valley. To investigate if growing hemp would fit into the farmers year course a ‘Deir Alla Agricultural Calendar’ was designed, based on the Gezer Calendar, a Hebrew inscription on limestone dated to ca. 925 BCE. Finally stalks of fiber hemp and examples of hempen thread and fabric will reveal how the material looks and… feels.

Published: July 2021

Prokaryotic microbial cells especially bacteria are highly emphases for their exopolysaccharides (EPS) production. EPS are the higher molecular weight natural extracellular compounds observe at the surface of the bacterial cells. Nowadays bacterial EPS represent rapidly emerging as new and industrially important biomaterials because it having tremendous physical and chemical properties with novel functionality. Due to its industrial demand as well as research studies the different extraction processes have been discovered to remove the EPS from the microbial biofilm. The novelties of EPS are also based on the microbial habitat conditions such as higher temperature, lower temperature, acidic, alkaliphilic, saline, etc. Based on its chemical structure they can be homopolysaccharide or heteropolysaccharide. EPSs have a wide range of applications in various industries such as food, textile, pharmaceutical, heavy metal recovery, agriculture, etc. So, this review focus on the understanding of the structure, different extraction processes, biosynthesis and genetic engineering of EPS as well as their desirable biotechnological applications.
SYNTHESIS AND CHARACTERIZATION OF TEMOZOLOMIDE LOADED THERANOSTIC QUANTUM DOTS FOR THE TREATMENT OF BRAIN GLIOMA
Authors: Parashar Ashish Kumar
Published: July 2021

In the present study, we have synthesized a multifunctional nano-carrier for the targeted delivery of temozolomide to brain glioma cells. The synthesis involved the surface modification of Ag2S quantum dots (QDs) with PEG2000. Silver sulphide quantum dots (Ag2S QDs) have gained a lot of attention as a theranostic agent because they have outstanding optical and chemical features that make diagnosis and therapy easier at the same time. PEGylation of QDs provides active binding sites for the conjugation of other bio-molecules while also stabilising the carrier in a biological environment. Angiopep-2 (ANG-2), a 19-aa oligopeptide, was incorporated as a targeting agent for the specific targeting of the nano-carrier to the brain glioma cells. LRP1 (low-density lipoprotein receptor-related protein 1) is abundantly expressed in both brain capillary endothelial cells and glioma cells. Angiopep-2 can bind to LRP1 and use receptor-mediated transport to cross the blood–brain barrier. As a result, ANG can be employed to deliver drugs to both the brain and the tumour locations. Fourier transform infrared, ultraviolet-visible, and fluorescence spectroscopy were used to extensively examine the structural features and optical qualities. The efficiency of entrapment was determined to be 71±0.8%. At the lysosomal pH (pH 5.0), the prepared TMZ-ANG-PEG-QDs formulations show a sustained release pattern of TMZ (68.6±0.2 percent in 24 hr). Drug-loaded QDs had higher cytotoxicity and cellular uptake, and were taken up preferentially by malignant cells through receptor-mediated endocytosis pathways. As a result, we postulated that the synthesised QDs could be a good choice for theranostic applications, particularly for targeted drug delivery and cellular imaging at the same time.

Г. В. Адамович и Михаил Иванников (Вокруг «Дороги»)
Authors:   Tallinn  University, Данилевский Александр
Published: July 2021

Речь в статье о том, как уязвленный сириновской карикатурой на себя в романе «Дар» Адамович решил заслонить его (выместив таким образом на периферию читательского сознания) автором печатавшейся в том же номере парижских «Современных записок» повести «Дорога», намеренно завышая при этом талант М. Д. Иванникова и превознося его как своего рода «подлинного В. Сирина», – и это в то время, когда Иванников всеми силами тщился не походить на Сирина (хотя и использовал в своей художественной практике некоторые сириновские художественные находки). Комизм ситуации со временем еще более усугубился тем обстоятельством, что довольно скоро после того Адамович не только запамятовал фамилию пестуемого им «конкурента Сирину», но и напрочь утратил представление о его, Иванникова, творческой манере, – настолько, что не смог атрибутировать следующий шедевр прозаика – необычайно заинтриговавший этого авторитетного критика рассказ «Правила игры».
Экзистенциальные и топографические аспекты геопоэтики в романах Ирины Одоевцевой
Authors:   Институт литературоведения Люблинского католического университета Иоанна Павла II, Возьняк Анна
Published: July 2021

Целью статьи является анализ проблем геопоэтики в романах «Ангел смерти», «Изольда» и «Зеркало» с точки зрения экзистенциальных проблем: культурной и духовной отчужденности эмигрантов. Рассматриваются черты поэтики романов, и прослеживается вопрос, как онтологические элементы влияют на образ пространства, как осуществляется парадигма «человек – место». Данная проблематика видится также в аспекте новаторских эстетических тенденций прозы 30-хх гг. XX в. (кампа и массовой культуры). В романах автора доминирует городское пространство, топосы «городов памяти» (Москва, Петербург) и реальных городов (Париж, Ницца, Венеция). Важным выводом анализа становится обнаружение приема транслирования чувств героинь романов на описываемые объекты пространства.

What’s the Matter with Jarrettsville? Genre Classification as an Opportunistic Construct
Authors: Childress C. Clayton
Published: July 2021

The study of genre classifications within creative industries typically orients  toward the maintenance of order within organizational and institutional contexts. This study takes up the case of Jarrettsville, a work of fiction published in the United States in Fall 2009 to highlight prevalent disorders and debates in the development of a work of fiction. What looks like a clear and ordered process of genre assignment after-the-fact may actually contain a wealth of negotiations, strategic practices, and decisions to be made. In short, the assignment of genres can be conflicted, debated and opportunistic. As a work of culture is transmuted into a piece of commerce, cultural workers must navigate the interplay between text and context, and sometimes with competing agendas. When texts don’t fit a preferred context, the text itself may change. And when the context of the texts’ fabrication as a piece of commerce does not fit the text, contexts must be mediated as well.

This case study highlights these processes in action.

OBJECTIVES The objectives of this study were to understand the
challenges faced by early adopters of MIS mitral surgery in the national
health system in the United Kingdom. It was to (i) capture the
significance of the scrutiny introduced by reporting surgeon specific
results during the introduction of surgical innovation, (ii) understand
how individual personality and behaviour helped these surgeons succeed
despite, in many cases, little wider support, (iii) to help more
surgeons adopt these patient-centred techniques. SETTING AND
PARTICIPANTS The study is based on a qualitative exploration of the
reported experiences of all ten early adopters of MIS cardiac surgery in
the NHS between 2006-2016. Interviewees were recruited by invitation
through their professional society (BISMICS). All interviewees consented
to the process; ethical permission was not deemed necessary. RESULTS The
experience of introducing surgical innovation into the NHS was
unanimously noted to be difficult with few incentives and many systemic
and institutional obstacles. Despite this there was a general belief in
pushing forward with these patient centred procedures while accumulating
the evidence to support it. CONCLUSIONS Individual determination,
confidence, mental agility and self-reflection were seen as
characteristics of those who were successful. All surgeons agreed that
the reporting of surgeon specific results were not conducive to adoption
of innovation in teams. Starting a new program as two surgeons appeared
to help reduce perceived pressures. Surgical innovation and its early
adoption are always likely to be difficult and needs to be recognised as
such, within the NHS

Published: July 2021

Introduction. Calcium silicate (CS) dental cements have numerous clinical
indications in dentistry including pulp capping, root end surgery,
perforation repair and apexification/apexogenesis treatment. Materials and
methods. Novel CS based dental cement with incorporation of SrCO3
radiopacifier named ALBO-DENT was used as an experimental cement material
while Portland cement (Aalborg, Denmark) and ProRoot MTA (Tulsa Dental, USA)
were used as controls. The radiopacity evaluation was performed using
digital Trophy Radiographic system with an intention to precisely determine
the minimum of radiopaque agent needed to confer to ISO radiopacity
requirement. Thereafter, biocompatibility of material was tested in in vitro
conditions in mouse fibrosarcoma L929 cell culture treated with materials?
extracts. Cell morphology was observed using phase-contrast microscopy,
while cell viability was measured using crystal violet (CV) and
3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assays.
Results. Radiopacity evaluation revealed that 30%wt addition of SrCO3 was
necessary to achieve satisfactory radiopacity (3.45 mm Al). Cytotoxicity
analysis using CV and MTT assays revealed that pure extracts of ALBO-DENT
presented superior biocompatibility when compared to PC and MTA controls
while serial dilutions of experimental cements? extracts as well as that of
PC and MTA did not influence L929 cell viability. Conclusions. Novel
formulation of CS cement - ALBO-DENT presented satisfactory radiopacity and
adequate biocompatibility.

Published: July 2021

Introduction. Dental caries is, along with periodontitis, the most frequent
oral disease and represents a chronic, progressive, multifactorial process
that leads to loss of hard dental tissues. The oral health status analysis
and caries risk factors assessment in early childhood and adolescence are
necessary for creating strategies in oral health promotion and preventive
treatment. The aim of the present study was to evaluate caries prevalence in
12 and 15-year-old schoolchildren in Cukarica, a municipality of Belgrade.
Material and method. The retrospective study included 409 schoolchildren of
both genders. The oral health status was registered using the Klein-Palmer
DMFT system (D - Decayed, M - Missing, F - Filled teeth). The methods of
descriptive statistics were performed and p-values lower than 0.05 were
considered statistically significant. Results. The younger group included
214 children (52.3%) and the older group 195 (47.7%). Individual caries rate
was higher in 15-year-old children (81.02%) comparing to 12-year-old (57%).
The mean value of decayed teeth for all participants was 2.43 and of total
DMFT was 8.99%. Conclusions. Oral health promotion programs gave positive
results. Moreover, it is important to implement them in the underdeveloped
regions of Serbia with an improvement of the oral health literacy of parents
and raising awareness of oral diseases.
Farm animal welfare: A key component of the sustainability of farming systems
Authors: Broom Donald
Published: July 2021

Consumers of food and other products now demand sustainability of production methods and, for most people, the welfare of production animals is an important component of sustainability. Products are not considered to be of good quality unless the welfare of the production animals is good. This is part of a more general change in knowledge that there are few differences between humans and other animal species, with the conclusion that each individual life should be valued and that causing poor welfare to a farmed animal is morally wrong. All vertebrate animals and some invertebrates are now shown to be sentient, that is they have the capacity to have feelings. There have been major advances in animal welfare science so that housing and management systems that result in poor welfare of the animals are now identified and every producer needs to change their systems and methods to ensure good welfare and avoid all of the worst welfare problems.

Paraffins and paraffin waxes are chemically stable. For that reason, for many types of oil, the treatment of high-paraffinic oils is conducted with the addition of modifiers of rheological properties. The flow properties of high paraffin oils are affected by the number and shape of formed paraffin crystals. The process of modifying of rheological properties of high paraffin oils consists of adding certain additives, which enable a change in the morphology of paraffin crystals. Adding additives to oil is most effective at pressures and temperatures at which paraffin crystallization has not yet occured. There is a large number of additives that have different applications. One of them is an additive that is used to lower the melting point and shear stress, and it is called a melting depressant. In crude oil, the total content of paraffin and the distribution of paraffin vary significantly. Therefore, for each type of oil the most effective melting point depressant is invented and developed separately. Other additives are paraffin inhibitors, paraffin removers and flow enhancers. The application of modifiers of rheological properties is important in solving the problem of flow of high paraffin oils. With this method, the problem of flow in the tubing, well lines, process vessels and oil pipeline is solved in the well.

Concept “ideal technology of food preservation“ represents procedure which is efficient during inactivation of toxic microorganisms and microorganisms that cause bleeding, which helps to preserve nutritive and organoleptic food properties. There are not any negative consequencies in the final product, which is economically competitive and ensures profitability for food processing industry. For inactivation of microorganisms which are transmitted by food in food processing industry, mainly is used thermal treatment. However, heating of products causes the loss of sensory properties ( texture, taste, smell and color ) and nutritition quality of products ( reduction of biology active compound content ). As the interest of production companies is closely linked to implementation of process, by which simulatenously can be reduced microbiological ballast and preserve the quality of food products. These procedures are known as alternative or mild technologies for food preservation. In this chapter, there has been given the overview of contemporary studies, which are related to development and application of application of new preservation technologies during processing of vegetable origin raw materials. Apart from that, there have been analyzed opportunities of their application in future for comercial use in industrial conditions.

The structure of cationic starch derivatives was characterized by using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The properties of materials such as cationic degree, viscosity, swelling capacity, solubility and moisture content were determined according to standard methods. The degree of cationization of the prepared cationic starches varied from 0.048 to 0.162 mmol g-1for samples with GTMAC and from 0.032 to 0.156 mmol g-1for samples with BHC. The FTIR and SEM characterization showed that incorporation of a cationic moiety onto the backbone of the starch was successful.

Entre las diferentes tipologías, la vivienda constituye el tipo constante a lo largo de la historia. En tal condición, es el más acertado para abordar el análisis de cómo llegan los modelos centrales a la realidad argentina en un incipiente movimiento moderno durante la primera parte del siglo XX. El epicentro receptor de esas nuevas ideas es Buenos Aires y como adherente principal a las respuestas universales, es a la vez el emisor de tales respuestas a provincias como Córdoba, Tucumán y Rosario, las cuales buscan desde el interior de las regiones la propia arquitectura entre posturas particulares y exógenas. Con el propósito de reflexionar acerca de las distintas miradas a ese movimiento moderno transculturado, en el presente artículo se recurre a casos de estudios concretos en los que cada exponente busca dotar de identidad a las propuestas formales mediante la comprensión del espíritu del lugar y del tiempo, para generar así soluciones singulares en el territorio argentino.

El presente artículo de reflexión indaga en diversos procesos de diseño de la vivienda unifamiliar latinoamericana de los siglos XX y XXI. Dicha tipología, una de las más constantes a lo largo de la historia, se ha mantenido casi inmutable en lo esencial, es decir, en espacios para reunir a la familia, servicios a diferentes escalas y ámbitos para descansar. Lo variable, enfocado en el lenguaje y su significado, ha evidenciado la participación del propietario en el juego de poder de cada momento por medio de tipos que manifiestan el espíritu de la época y el del lugar al introducir innovaciones. En la medida que la vivienda ayuda a construir, delinear y manifestar la identidad de cada región y el carácter mestizo de nuestra cultura, a través de ella se reflejan tensiones entre lo local y lo global, el presente y el futuro, y se ponderan conceptos propios del paisaje donde se inserta. Entre tendencias centrípetas y centrífugas, entre lo auténtico y lo ilimitado, las construcciones se acercan a la hibridez conceptual y formal característica del diseño latinoamericano, definido desde sus orígenes por la riqueza contenida en sus multiformes fisonomías.
El habitar en altura en la Córdoba moderna del siglo XX
Authors: Carmignani Mara Gabriela
Published: July 2021

El presente artículo expone reflexiones acerca de las tipologías residenciales colectivas que durante las primeras décadas del siglo XX se crearon en Argentina, particularmente en la ciudad de Córdoba, a partir de procesos de transculturación de modelos del Movimiento Moderno procedentes de realidades europeas. La temática se aborda desde el significado ontológico del habitar, para ordenar luego la vivienda en altura en clasificaciones de tiempo y espacio en que el interés particular se acentúa en el componente antropológico y geográfico latinoamericano. Las propuestas logradas reflejan cómo las búsquedas se adaptan a los modelos universales o generan reelaboraciones propias para conferirles un carácter singular y regional, en medio de un fenómeno de modernización definido por nuevos modos de vida, nueva cultura urbana y nuevas condicionantes del habitar.
Una pedagogía para el objeto de diseño industrial digital
Authors: Vidal Prada Ernesto
Published: July 2021

Para la sección “Disertaciones sobre Diseño del Vol 6, Nº 1 de la revista Designia, el autor invitado presenta un artículo corto de reflexión, en el que se discute acerca de la enseñanza y aprendizaje del diseño industrial en contextos digitales.

En este caso, a partir de la propuesta pedagógica titulada “Aulas con sentido” en la cual se plantea un esquema básico y punto de partida para pensar el uso de herramientas digitales dentro de cursos académicos de un programa de Diseño Industrial.

De acuerdo con la experiencia descrita, la reflexión implica la realidad de la disciplina más allá del uso de la tecnología, en este caso a partir de la representación digital del objeto de diseño de diseño, su función comunicativa y vinculación con el contexto.
color en la revitalización del patrimonio modesto
Authors: Mariconde María Marta , Incatasciato Adriana
Published: July 2021

Los cambios culturales contemporáneos invaden los sentimientos de pertenencia y el desarrollo del sentido de lugar, como una necesidad del hombre de identidad con su ciudad. El lugar está ligado a la identidad. Cada grupo humano sostiene una relación muy estrecha con su lugar, con su territorio, ejerce una apropiación del mismo, posee un sentimiento de pertenencia y de orientación en él.

Ese sentimiento de “pertenecer a” implica compartir intereses, memorias y experiencias con otros; poseer valores en común y sentimientos profundos de identificación, además de situarse en un territorio compartido. Al respecto, según Marina Waisman, el concepto de identidad implica el de unidad, adquiriendo sentido si está en presencia de una multiplicidad que le es ajena. Así pues, la identidad de un grupo humano se va construyendo al tiempo que va calificando el propio entorno.

El enfoque sobre la imagen morfológica expresiva deviene en uno de los instrumentos de lectura del desarrollo urbano para todas aquellas intervenciones que alteran la consolidación del tejido. Desde esta mirada, el color, como atributo ligado a la forma, debe ser considerado un importante recurso en la estructuración de la imagen, conformándose en un referente del entorno. El color verifica y sustenta su actuación, construye, acentúa o materializa la imagen, logrando ser referente identificatorio, de apropiación y arraigo del ciudadano. En este sentido es considerado como una de las herramientas más fuertes, tanto eficaces cuanto económicas, para la revalorización y puesta en valor de micro-áreas con valor de patrimonio modesto, en un corto plazo.

Para la recuperación del imaginario cultural de una región se debe trabajar entonces en la consolidación y recuperación de la identidad, logrando la puesta en valor del patrimonio vivo, arquitectónico y social. En ese sentido, se presentarán propuestas de intervenciones cromáticas realizadas en localidades del interior de la provincia de Córdoba, Argentina.
Trofozoito de Entamoeba coli con cuatro núcleos
Authors: Traviezo-Valles Luis Eduardo , Galindez Andrea
Published: July 2021

Entamoeba coli (E. coli) fue identificada primeramente por Lewis (1870), pero fue Gras en 1877 quien hace su descripción. Es un parásito comensal que habita el intestino grueso del humano y su presencia siempre ha estado asociada a la patógena Entamoeba histolytica; en condiciones normales el trofozoito de E. coli debe medir entre 15 y 50 µ, se mueve poco y sin direccionalidad definida, emitiendo seudópodos romos, cortos, no hialinos y sin apreciarse una diferenciación clara entre ectoplasma y endoplasma. El trofozoito presenta un solo núcleo que al teñirlo, permite apreciar un cariosoma irregular, no compacto, de gran tamaño, excéntrico y una cromatina perinuclear que tiene forma de gránulos gruesos e irregulares.
Del yo metafísico al yo psíquico
Authors: Alemany Navarro Pedro David
Published: July 2021

En este artículo se mostrarán, desde una perspectiva diacrónica, las fórmulas retóricas de conversión presentes en el autorretrato del pensador que se embarca en el viaje introspectivo, retrospectivo y alterspectivo que supone el proceso de auto-escritura. Por otra parte, se enmarcará también la evolución del yo metafísico al yo psíquico en la historia de la autobiografía filosófica; evolución estrechamente relacionada con una progresiva secularización de la retórica de conversión y del proceso de auto-escritura mismo.

La condición transcendental de la libertad según Fichte
Authors: Justo Domínguez Emilio-José
Published: July 2021

El pensamiento de Fichte supone el hecho de la libertad y mediante el análisis del yo ofrece un fundamento transcendental para su afirmación. Así contribuye a elaborar un concepto de libertad que permite pensar la conciencia del ser humano, su relación con los demás y su organización política. En este artículo se presentan las líneas fundamentales de la filosofía de Fichte que se refieren a la condición transcendental de la libertad y a su relación con el absoluto. Además, se intentan mostrar las potencialidades del idealismo para pensar la realidad desde la libertad.
Plate Structural Analysis Based on a Double Interpolation Element with Arbitrary Meshing
Authors: Ton-That Hoang Lan
Published: July 2021

This paper presents the plate structural analysis based on the finite element method (FEM) using a double interpolation element with arbitrary meshing. This element used in this research is related to the first-order shear deformation theory (FSDT) and the double interpolation procedure. The first stage of the procedure is the same with the standard FEM for the quadrilateral element, but the averaged nodal gradients must be computed for the second stage of this interpolation. Shape functions established by the double interpolation procedure exhibit more continuous nodal gradients and higher-order polynomial contrast compared to the standard FEM when analysing the same mesh. Note that the total degrees of freedom (DOFs) do not increase in this procedure, and the trial solution and its derivatives are continuous across inter-element boundaries. Besides, with controlling distortion factors, the interior nodes of a plate domain are derived from a set of regular nodes. Four practical examples with good results and small errors are considered in this study for showing excellent efficiency for this element. Last but not least, this element allows us to implement the procedure in an existing FEM computer code as well as can be used for nonlinear analysis in the near future.
