Background

Establishing rapport and empathy between patients and their health care provider is important but challenging in the context of a busy and crowded emergency department (ED).

Objective

We explore the hypotheses that rapport building, documentation, and time efficiency might be improved in the ED by providing patients a digital tool that uses Bayesian reasoning–based techniques to gather relevant symptoms and history for handover to clinicians.

Methods

A 2-phase pilot evaluation was carried out in the ED of a German tertiary referral and major trauma hospital that treats an average of 120 patients daily. Phase 1 observations guided iterative improvement of the digital tool, which was then further evaluated in phase 2. All patients who were willing and able to provide consent were invited to participate, excluding those with severe injury or illness requiring immediate treatment, with traumatic injury, incapable of completing a health assessment, and aged <18 years. Over an 18-day period with 1699 patients presenting to the ED, 815 (47.96%) were eligible based on triage level. With available recruitment staff, 135 were approached, of whom 81 (60%) were included in the study. In a mixed methods evaluation, patients entered information into the tool, accessed by clinicians through a dashboard. All users completed evaluation Likert-scale questionnaires rating the tool’s performance. The feasibility of a larger trial was evaluated through rates of recruitment and questionnaire completion.

Results

Respondents strongly endorsed the tool for facilitating conversation (61/81, 75% of patients, 57/78, 73% of physician ratings, and 10/10, 100% of nurse ratings). Most nurses judged the tool as potentially time saving, whereas most physicians only agreed for a subset of medical specialties (eg, surgery). Patients reported high usability and understood the tool’s questions. The tool was recommended by most patients (63/81, 78%), in 53% (41/77) of physician ratings, and in 76% (61/80) of nurse ratings. Questionnaire completion rates were 100% (81/81) by patients and 96% (78/81 enrolled patients) by physicians.

Conclusions

This pilot confirmed that a larger study in the setting would be feasible. The tool has clear potential to improve patient–health care provider interaction and could also contribute to ED efficiency savings. Future research and development will extend the range of patients for whom the history-taking tool has clinical utility.

Patients’ Perspectives on Qualitative Olfactory Dysfunction: Thematic Analysis of Social Media Posts
Authors: Parker Jane K , Kelly Christine E , Smith Barry C , Kirkwood Aidan F , Hopkins Claire , Gane Simon
Published: December 2021

Background

The impact of qualitative olfactory disorders is underestimated. Parosmia, the distorted perception of familiar odors, and phantosmia, the experience of odors in the absence of a stimulus, can arise following postinfectious anosmia, and the incidences of both have increased substantially since the outbreak of COVID-19.

Objective

The aims of this study are to explore the symptoms and sequalae of postinfectious olfactory dysfunction syndrome using unstructured and unsolicited threads from social media, and to articulate the perspectives and concerns of patients affected by these debilitating olfactory disorders.

Methods

A thematic analysis and content analysis of posts in the AbScent Parosmia and Phantosmia Support group on Facebook was conducted between June and December 2020.

Results

In this paper, we identify a novel symptom, olfactory perseveration, which is a triggered, identifiable, and usually unpleasant olfactory percept that persists in the absence of an ongoing stimulus. We also observe fluctuations in the intensity and duration of symptoms of parosmia, phantosmia, and olfactory perseveration. In addition, we identify a group of the most common items (coffee, meat, onion, and toothpaste) that trigger distortions; however, people have difficulty describing these distortions, using words associated with disgust and revulsion. The emotional aspect of living with qualitative olfactory dysfunction was evident and highlighted the detrimental impact on mental health.

Conclusions

Qualitative and unsolicited data acquired from social media has provided useful insights into the patient experience of parosmia and phantosmia, which can inform rehabilitation strategies and ongoing research into understanding the molecular triggers associated with parosmic distortions and research into patient benefit.

Authors: Kwun Ju-Seung , Yoon Chang-Hwan , Kim Sun-Hwa , Jeon Ki-Hyun , Kang Si-Hyuck , Lee Wonjae , Youn Tae-Jin , Chae In-Ho
Published: December 2021

BACKGROUND

Acute myocardial infarction may be associated with new-onset arrhythmias. Patients with myocardial infarction may manifest serious arrhythmias such as ventricular tachyarrhythmias or atrial fibrillation. Frequent, prolonged electrocardiogram (ECG) monitoring can prevent devastating outcomes caused by these arrhythmias.

OBJECTIVE

We aimed to investigate the incidence of arrhythmias in patients following myocardial infarction using a patch-type device—AT-Patch (ATP-C120; ATsens).

METHODS

This study is a nonrandomized, single-center, prospective cohort study. We evaluated 71 patients who had had a myocardial infarction and had been admitted to our hospital. The ATP-C120 device was attached to the patient for 11 days and analyzed by 2 cardiologists for new-onset arrhythmic events.

RESULTS

One participant was concordantly diagnosed with atrial fibrillation. The cardiologists diagnosed atrial premature beats in 65 (92%) and 60 (85%) of 71 participants, and ventricular premature beats in 38 (54%) and 44 (62%) participants, respectively. Interestingly, 40 (56%) patients showed less than 2 minutes of sustained paroxysmal atrial tachycardia confirmed by both cardiologists. Among participants with atrial tachycardia, the use of β-blockers was significantly lower compared with patients without tachycardia (70% vs 90%, P=.04). However, different dosages of β-blockers did not make a significant difference.

CONCLUSIONS

Wearable ECG monitoring patch devices are easy to apply and can correlate symptoms and ECG rhythm disturbances in patients following myocardial infarction. Further study is necessary regarding clinical implications and appropriate therapies for arrhythmias detected early after myocardial infarction to prevent adverse outcomes.

Published: December 2021

Генералізований пародонтит є одним із найчастіших стоматологічних захворювань, що може призвести до рухомості та втрати зубів. Основним його етіологічним чинником є зубний наліт, однак генералізований пародонтит є мультифакторним захворюванням. Наявні дані про вплив рівня вітаміну D на генералізований пародонтит. Вітамін D справляє плейотропну дію, впливаючи на різні ланки патогенезу генералізованого пародонтита. Стимулюючи секрецію антимікробних пептидів, вітамін D підвищує місцевий імунітет та негативно впливає на пародонтопатогени; модулюючи імунну систему, впливає на перебіг запалення в тканинах пародонта та імунну відповідь; підвищуючи всмоктування кальцію та зменшуючи виділення паратгормона, стимулює мінералізацію кісткової тканини. Висока поширеність дефіциту та недостатності вітаміну D у всьому світі говорить про актуальність вивчення його впливу на організм людини загалом та ротової порожнини зокрема.

Published: December 2021

Objective: Kaempferia galanga L. rhizome (KGR), has been empirically used in Indonesia, particularly by Javanese, to cure inflammation. KGR contains various secondary metabolites which explain its pharmacology activities, among them is ethyl p-methoxycinnamate (EPMC). However, due to the different seasons of our country, the yield of extraction is often unalike. In this work, we determined the percentage of yield (w/w), the water content (thermogravimetric method), and the concentration of EPMC in the Ethanol extract of Kaempferia galanga L. Rhizome (EEKG) harvested from the rainy (EEKG-R) and dry seasons (EEKG-D).

Methods: The sun-dried rhizomes were cold macerated for 3x24 h with 70% ethanol, filtered, and the solvent was evaporated at 40-45 °C until a viscous extract was obtained. The determination of EPMC in the extract was carried out using the RP-HPLC standard addition method. Detection was set at 308 nm; injection volume 20 µl; flow rate 1.0 ml/min. The column used is C18 (length 250 mm, internal diameter 4.6 mm, particle size 5 µm).

Results: The yield of EEKG-R (harvested in the rainy season) = 14.56% w/w, water content = 4.37%, and the EPMC = 0.01%. Meanwhile the yield of EEKG-D (harvested in the dry season) = 5.79% w/w, water content = 18.76%, and the EPMC = 0.001%.

Conclusion: Different climates affect the percentage yield and the quality of the extract. In our work, the EEKG-R (harvested in the rainy season) revealed a better quality compared to that of EEKG-D (harvested in the dry season) This study gives important information to standardize and optimize the harvest time of KG rhizomes for drugs development, which are strongly influenced by seasonal differences.

Published: December 2021

Objective: Noni fruit (Morinda citrifolia L) and cinnamon bark (Cinnamomum burmannii) are plants that have the hypoglycemic effect on their ethyl acetate fraction in the single dose. This study was to determine the hypoglycemic activity of the combination of ethyl acetate fraction (FEM) and cinnamon bark (FEC) in glucose-induced mice, as well as the dose of the combination of FEM and FEC which could have a hypoglycemic effect.

Methods: The methods were including extraction using liquid-liquid extraction, identification by TLC, and assay of hypoglycemic activity in mice induced by oral glucose for a moment in the eight groups that were normal control, negative control, positive control, dose 1-5. The activity tests were performed at 30th, 60th, 90th and 120th of minutes.

Results: The research showed that the yield of FEM and FEC were 5.25% and 8.05%. Identification of compounds by TLC showed that the FEM and FEC were 4 and 3 spots. The results of a hypoglycemic test showed that the combination of FEM and FEC on glucose-induced mice showed a decreased effect of mice blood glucose levels better than a single dose of these fractions.

Conclusion: The hypoglycemic activity test at a combined dose of FEM 175 mg/kg BW and FEC 150 mg/Kg BW have provided hypoglycemic activity better compared to other dose groups with a percentage decrease in average relative blood glucose at the 30th, 60th, 90th, 120th minute were 29.57%, 44.94%, 43.40% and 40.55%, respectively. Thus, the combination of the FEM and FEC in glucose-induced mice gave a hypoglycemic effect in mice.

Published: December 2021

Objective: This study was aimed to evaluate the role of genistein or 4',5,7-trihydroxyisoflavone as a phytoestrogen in the treatment of estrogen deficiency-induced neuroinflammatory. The specific objectives of this study were to determine the anti-neuroinflammatory effect of genistein through measurement of MHC II and Arg1 expressions on microglia HMC3 cell line, as well as to prove that the effect occurs in an ER-dependent manner, through the measurement of free-ERβ expression.

Methods: The cells were cultured in 24-well microplates, induced with 10 ng IFN-γ, and incubated for 24 h to activate the cell to M1 phenotype which has pro-inflammatory characteristics. Genistein with a concentration of 50 μM was added to the cells. The expression of MHC II, Arg1, and free-ERβ as markers was tested through an immunocytochemistry method and measured using the CLSM instrument. In silico approach was also conducted to determine the interaction between genistein and ERβ, compared to 17β-estradiol. Genistein structure was prepared with Avogadro 1.0.1, and molecular docking was done using PyRx 0.8 software. Biovia Discovery Studio Visualizer 2016 was used to visualize the structure of genistein against 3OLS protein. The physicochemical characteristics of genistein were analyzed using the SwissADME web tool.

Results: Genistein can decrease MHC II expression and increase Arg1 expression in microglia HMC3 cells compared to negative controls (p<0.005), with expression value of 472.577±26.701 AU and 114.299±6.578 AU. But, genistein cannot decrease the free-ERβ expression in cells (p<0.005). The results of in silico analysis showed that genistein is an ERβ agonist.

Conclusion: Genistein shows anti-neuroinflammatory effects by decreasing the MHC II expression and increasing Arg1 expression in the microglia HMC3 cell line. However, this effect does not occur through the binding of genistein to ERβ, but it is likely to occur through the binding of genistein with other types of ER.

Published: December 2021

In the coffee zone of the town La Unión- Nariño, native or introduced trees are associated with the productive systems of the farms, mainly because they provide shade for coffee crops, where particular aspects such as species biodiversity and silvicultural management are unknown. With the aim of knowing the woody species of common use and the cultural importance, a semi structured survey was applied to 100 coffee growers who were selected at random and aleatorily distributed in three altitudinal ranges: (m.a.s.l.): I (<1500), II (1500-1800) and III (> 1800). Species richness was determined for each chosen range; for diversity between ranges, the Jaccard Index (JI) and the Cultural Importance Index (CI) were used. The latter was determined by adding up the intensity of use (IU), frequency of citation (FC), and use value (UV). In the three altitude ranges evaluated, 59 tree species were found. These were distributed in 32 botanical families and 46 genera. The fabaceae family was the most representative, followed by rutaceae, myrtaceae and bignoniaceae; 45.8% of the species were introduced. Among the altitudinal ranges, a low degree similarity was found; ranks I and II shared 24 species, which is equivalent to 33.8% of their floristic composition. As for ranges I and III, they had an even lower degree of similarity: 24.2%; only 17 species were shared. The species I. densiflora had the highest percentage of CI, with 32.92%, followed by C. sinensis with 31.98%; then the species T. gigantea and P. americana with 30.49% and 26.27% respectively. These species were of great importance to coffee growers due to the positive impact they have on the family economy and their contribution to the environmental well-being of production systems.

Las comunicaciones de misión crítica utilizadas a nivel mundial para la seguridad pública han estado basadas en soluciones de banda angosta, enmarcadas en los diferentes protocolos incluidos en Land Mobile Radio (LMR), como APCO 25, utilizado por la Policía Nacional. Si bien estas tecnologías han sido de gran importancia y cuentan con una madurez de implementación bastante consolidada para la transmisión confiable de voz, tienen limitantes para la transmisión de datos como imágenes y videos, por lo que se hace necesario el aprovechamiento de una tecnología como Long Term Evolution (LTE). Teniendo en cuenta esta necesidad, se llevó a cabo una revisión de la literatura científica-técnica, realizando un análisis del estado del arte de artículos seleccionados de varias bases de datos; asimismo, se determinaron criterios de inclusión y exclusión para el estudio, gracias a lo cual se logró identificar que hoy en día no se tiene la capacidad tecnológica para realizar un desarrollo de una red LTE para seguridad pública; con base en lo anterior, se identificó la necesidad de una implementación tecnológica que garantice la coexistencia de las dos redes LMR y LTE, aprovechando las bondades de cada una de ellas en una suma que incrementa las capacidades tecnológicas en el servicio de policía.

Las obligaciones internacionales contraídas por Colombia que garantizan derechos y libertades exigen su cumplimiento en favor de los habitantes del territorio. A pesar de esto, cada año el Estado resulta responsable por violaciones en ese sentido, evidenciándose en ocasiones el desconocimiento respecto de mecanismos efectivos de protección de los derechos por parte de la sociedad y de las víctimas, fomentándose así la impunidad. Se pretende a través de esta investigación basada en problemas exponer de manera crítica el mecanismo de queja del Comité de Derechos Humanos de la ONU, mediante una propuesta que acerque los enfoques académicos a la resolución de los problemas reales de la sociedad a partir del análisis de casos decididos por el Comité en contra de Colombia, para proponer la necesidad de generar desde la educación una cultura efectiva de promoción, divulgación y protección de derechos, libertades y garantías previstas en instrumentos internacionales. Finalmente, se evidencia el escaso aprovechamiento que se da al Comité y el desconocimiento de sus funciones, como también el hecho de que Colombia sigue presentando altos índices de violación a los derechos humanos, sobre todo respecto de las garantías de acceso a la justicia.
Strategies of the Texts Translation Published on the Languages of the Indiginous Peoples of the Russian Far East
Authors: Osipova Marina V.
Published: December 2021

Lately more and more articles are published, in which the problem of translation the works written in the native languages of the indigenous peoples of Russia are touched upon. Their authors (Yu.V. Limorenko, A.M. Kotorova, N.Ya. Bulatova etc.) emphasize the importance of such translation in popularization the cultural heritage of these peoples. However there isnt any research that highlights the questions of creation of the corpus of translated texts, what kind of methods and strategies were used by translators. It should be mentioned that that the corpus of translated texts can be divided into two types. The first type includes texts written and translated by scientists, missionaries and historians. To the second type belong texts translated by amateur and professional writers. That is why the aim of this article is to answer the question about the stages of the creating of the corpus of the translated from the native languages texts, to determine the most productive methods of translation and to find out what strategies of translation were used by the translators - whether they used their own knowledge of the native languages or interlinear translation, or processed the translation made by the author himself. To achieve this aim the comparative-historical and hermeneutic approaches are used.

Published: December 2021

Climate change causes fluctuations in temperature and precipitation. As
a result, it affects the discharge of rivers, the most important
consequence of which is the tendency toward extreme events such as
torrential rains and widespread droughts. River discharge is one of the
most important climatic and hydrological parameters. Investigating the
changes in this parameter is one of the main prerequisites in the
management and proper use of water resources and rivers. Most trend
detection studies are based on analyzing changes in the mean or middle
of the data. They do not provide information on how changes occur in
different data ranges. Therefore, to investigate parameter changes in a
different range of the data series, various regression models were
proposed. Frequentist quantile regression and Bayesian quantile
regression models were used to estimate their trend and trend slope in
different quantiles of discharge in different seasons of the year for
Arazkouseh, Tamar, and Galikesh stations of Gorganroud basin in northern
Iran with the statistical period of 1346–1396 (1966–2016). The results
show that in most seasons of the year, high discharge rates for all 3
stations have decreased with a steep slope, and only in summer, Tamar
and Galikesh stations have had an increasing trend, but low discharge
rates have not changed significantly. Spatially, the discharge values at
Arazkouseh station have a decreasing trend with a higher slope rate, and
in terms of time, the most decreasing trend has been in spring.
Comparing the models also shows that the Bayesian quantile regression
model provides more accurate and reliable results than the
frequency-oriented quantile regression model. In general, quantile
regression models are useful for predicting and estimating extreme high
and low discharge changes for better management to reduce flood and
drought damage.

Background. Kaposiform hemangioendothelioma (KHE) is a rare vascular
tumor of infancy commonly associated with Kasabach-Merritt phenomenon
(KMP) that includes thrombocytopenia and coagulation dysfunction.
Platelet receptor CLEC-2 -tumor cell podoplanin interaction is
considered the key mechanism of thrombocytopenia in KMP, however, the
effect of long-term exposure to podoplanin on platelet function is
unknown. Procedure. Here we examined blood samples from six patients
with KHE and one KMP. Platelet calcium signaling and functional
responses to conventional activation and CLEC-2 stimulation were
analyzed by continuous and endpoint live cell flow cytometry. Platelet
aggregation in response to ADP or rhodocytin was analyzed by low-angle
light scattering approach (LaSca). Additionally, ex vivo thrombus
formation on collagen was observed in parallel-plate flow chambers.
Results. We demonstrate that in KHE/KMP platelet functional responses to
strong stimulation were on the lower boundary of age-matched normal
ranges, while calcium mobilization and fibrinogen binding upon
stimulation with ADP alone were significantly lower than control values.
Platelet di-aggregate formation in response to ADP was also diminished
in most of the patients. Formation of platelet aggregates in
collagen-coated parallel plate flow chambers was also noticeably lower
than in the age-matched control group. Calcium mobilization in response
to CLEC-2 stimulation was unaltered in the patients and could be blocked
by low-molecular-weight inhibitors, 2CP and HB125. Conclusions. While
platelet responsiveness in KHE/KMP is moderately altered, their CLEC-2
receptors remain functional and respond to inhibition. Therefore, our
findings suggest that CLEC-2-targeting molecules are new potential
agents in therapeutic management of this life-threatening condition.
The Effect of Mushroom Manager Behavior on Organizational Charlatan and Organizational Loneliness
Authors: ERGÜN Hüsnü
Published: December 2021

The mushroom-type manager expects employees not to have much knowledge on organizational issues, but to follow the instructions and directives without question. This study aims to examine the effect of the mushroom-type management approach on the loneliness levels of the employees and organizational charlatan behaviors. Therefore, the research is designed in a relational screening model. The research was carried out in the province of Denizli in Turkey with 464 participants. In the research, the mushroom type management scale, UCLA loneliness scale-3, and organizational charlatan scale were used.  Validity and reliability studies of the Turkish mushroom-type management scale for schools have been reconstructed. UCLA loneliness scale-3 and organizational charlatan scale were adapted to Turkish by the researcher.  The data were collected with the help of electronic forms. Regression analysis was carried out to determine the extent to which mushroom type management predicted teachers’ organizational loneliness behaviors and teachers' organizational charlatan behaviors. As a result of the research, it has been found that mushroom management positively affects the other two variables. For this reason, school principals can be suggested mushroom management behavior.

Authors: Arshed Saima , Mirhosseini-Alizamini Mehdi , Baleanu Dumitru , Rezazadeh Hadi , Inc Mustafa , Hussain Majid
Published: December 2021

This paper considers the non-linear Kudryashov's equation, that is an
extension of the well-known dual-power law of refractive index and is analog
to the generalized version of anti-cubic non-linearity. The model is
considered in the presence of full non-linearity. The main objective of this
paper is to extract soliton solutions of the proposed model. Three
state-of-the-art integration schemes, namely modified auxiliary equation
method, the sine-Gordon expansion method and the tanhcoth expansion method
have been employed for obtaining the desired soliton solutions.

Authors: Rana Siddra , Mehmood Rashid , Muhammad Taseer
Published: December 2021

The existing investigation highlights oblique Jeffrey fluid with mixed
convection on a stretched surface. Also chemical reactions with properties
of homogeneity and heterogeneity are considered. The leading physical model
is converted in a non-linear system of ODE by means of proper similarity
alterations. Influence of all relative physical constraints on velocity,
temperature as well as on concentration are expressed geometrically.
Physical magnitudes of interest like friction measurements, thermal and
concentration transport rates of chemical spices at the surface are studied
numerically.

Authors: Waheed Asif , Imran Ali , Javeed Shumaila , Baleanu Dumitru , Zeb Muhammad , Ahmad Sohail
Published: December 2021

In this study a novel mathematical model for electroosmotic flow for Cu-water
based nanofluid with heat transfer phenomenon is reported for
scraped-surface heat exchanger. The flow is initiated due to motion of lower
wall of the channel and axial pressure gradient. The flow is modelled with
aid of low Reynolds number and lubrication approximation theory. Exact
analytical expressions are gathered for axial velocity, and stream functions
for various stations of scraped-surface heat exchanger. Physical phenomenon
of electro osmotic parameter are investigated on velocity profile, velocity
distribution and pressure rise at edge of the blades. It is reported that
electro-osmotic parameter mainly works as dragging force, it can be used to
control the flow. This controlling mechanism may be helpful in mixing
different materials in scraped-surface heat exchanger. Pressure rise at edge
of the blades mainly rises below the blades with electro-osmotic, whereas,
this profiles is suppressed for region above the blades and between the
blades.

Authors: Khater Mostafa , Attia Raghda , Elagan Sayed , Bayones Fatma
Published: December 2021

In this paper, we study the soliton wave of the fractional Benjamin-Ono
equation based on the extended simplest equation method. The accuracy of the
obtained soliton wave solutions is investigated by comparing the obtained
analytical and semi-analytical solutions. The semi-analytical solutions are
constructed by applying the Adomian decomposition method. The
semi-analytical method is used based on the constructed initial and boundary
conditions from the obtained analytical solutions. Both solutions
(analytical and semi-analytical) are plotted through different techniques
for explaining the internal waves of deep-stratified fluids.
Numerical approach to simulate diffusion model of a fluid-flow in a porous media
Authors: Aghdam Yones Esmaeelzade , Farnam Behnaz , Jafari Hosein
Published: December 2021

When a particle distributes at a rate that deviates from the classical
Brownian motion model, fractional space derivatives have been used to
simulate anomalous diffusion or dispersion. When a fractional derivative
substitutes the second-order derivative in a diffusion or dispersion model,
amplified diffusion occurs (named super-diffusion). The proposed approach in
this paper allows seeing the physical background of the newly defined Caputo
space-time-fractional derivative and indicates that the order of convergence
to approximate such equations has increased.
Graphene-based Newtonian nanoliquid flows over an inclined permeable moving cylinder due to thermal stratification
Authors: Ghani Siti , Yarmand Hooman , Noor Noor
Published: December 2021

Heat flux enhancement due to utilization of graphene, graphene nanoplatelets,
and graphene oxides in water/ethylene-glycol based nanofluids over an
inclined permeable cylinder is focused in the present study. The governing
PDE are reformulated into non-linear ODE by applying similarity
expressions. A shooting procedure is opted to reformulate the equations
into boundary value problems which are solved by employing a numerical
finite difference code in MATLAB. The effects of constructive parameters
toward the model on non-dimensional velocity and temperature dissemination,
reduced skin friction coefficient and reduced Nusselt number are
graphically reported and discussed in details. It is observed that by
in-creasing the thermal stratification and inclination angle, the
temperature profile and Nusselt number for the selected nanofluids will be
decreased.
Non-differentiable solutions for non-linear local fractional heat conduction equation
Authors: Zhang Sheng , Zheng Xiaowei
Published: December 2021

Fractional calculus has many advantages. Under consideration of this paper is
a (2+1)-dimensional non-linear local fractional heat conduction equation
with arbitrary degree non-linearity. Backlund transformation of a reduced
form of the local fractional heat conduction equation is constructed by
Painleve analysis. Based on the Backlund transformation, some exact
non-differentiable solutions of the local fractional heat conduction
equation are obtained. To gain more insights of the obtained solutions, two
solutions are constrained to a Cantor set and then two spatio-temporal
fractal structures with profiles of these two solutions are shown. This
paper further reveals by local fractional heat conduction equation that
fractional calculus plays important role in dealing with non-differentiable
problems.
Sedimentation of two spheres in a square tube
Authors: Guan Geng , Ying Yuxiang , Nie Deming
Published: December 2021

In this study, we simulated the sedimentation of two identical spheres having
the same density in a square tube. Compared with the center-line and the
diagonal planes (including the reverse diagonal plane), the sedimentation of
spheres on other planes is more complicated. Results show that at relatively
low and high Reynolds number, the spheres will deflect and eventually move
to the diagonal plane of the square tube. At the medium Reynolds number, the
spheres settle near the initial plane. The possible mechanisms underlying
these behaviors are examined. Finally, it is shown that the distance
between the spheres increases with an increase in the Reynolds number, which
is applicable to all the initial settlement planes studied.

Self-Silencing Strategies in Casual Conversations about Politics in Rural Poland
Authors: Malewska-Szałygin Anna
Published: December 2021

Self-silencing can be a discursive strategy for presenting personal opinions in casual conversations about politics, especially when these take place in an unpredictable or hostile socio-political environment. In such situations, political identities may be performed through the use of inferred forms, such as allusion, irony or implicit suggestion. In this article, forms of muting one’s voice by using indirect speech are tracked in interviews conducted among villagers in the mountainous Nowy Targ county in southern Poland at the beginning of the 21st century. The aim in presenting these examples is to show that sometimes selfsilencing can serve to make an adversary’s voice more audible, to help avoid definitive judgement and to create space for an exchange of opinions.
Regimeideologi og politisk historiebrug i Rusland: Udstillingen »Rusland – Min Historie«
Authors: Suslov Mikhail
Published: December 2021

The article analyses representations of history in today’s Russia as part of the ideology for expressing central political concepts underlying the Putinist regime. Mainstream interpretations of history build on a populist vision of Russia as a community with a stable, unchangeable core of identity. In this ideological context, history serves as the canvas on which the ‘authentic’ Russian identity manifests itself. The present research article examines representations of history by focusing on the concepts of ‘historical sovereignty’, ‘unity of history’, and the role of elites in history. It finds that regime ideology in today’s Russia relies on a sizable infrastructure that involves producing historical knowledge for the purpose of securitizing history and making it an instrumental element in the populist (conservative-communitarian) ideology. Sources for this study come from the network exhibition ‘Russia – My History’, contextualized through content analysis of the key producers of ideology in Putin’s Russia.
