Numerical study on the flow past a finite-length tapered cylinder
Authors: Wang Shifeng , Zheng Kaixuan , Nie Deming
Published: January 2023

In this study, the flow past a finite-length tapered cylinder is numerically
investigated via the finite-volume method with Reynolds numbers ranging
from 50-250 and taper ratio l = 1.5. The corresponding lift and drag
coefficients, as well as the Strouhal numbers are presented. The factors
related to the discontinuity, through Reynolds numbers of 100 - 200, in the
lift coefficient, which is related to the wake structure of the tapered
cylinder, are explained. Furthermore, the influence of the wake structure
on the discontinuity in the lift coefficient is discussed. Finally, a
comparison of the Strouhal numbers between the circular cylinder and tapered
cylinder at the same Reynolds number is performed.

Published: January 2023

This paper's numerical study, which applies the finite volume approach and
SIMPLE algorithm, aims to dynamically analyze airflow through a channel with
Z-obstacles. Three distinct models were used to place the Z-barriers inside
the channel. According to Demartini et al.'s model (2004) and as depicted in
example A from the present analysis, the first Z-barrier (fin) is attached
to the top wall (heated) and the second (baffle) to the bottom wall
(insulated). The Z-barriers, on the other hand, were positioned in the
second model on the same wall (in-line arrangement), either on the top
surface (two fins in example B) or on the bottom wall (two baffles in
example C). With the help of these studies, fluid dynamics in solar air
collectors with barriers will be better understood and designed.

Published: January 2023

The lattice Boltzmann method has become a promising numerical technique and
is now being considered as an alternative to the conventional CFD methods
owing a possibility to simulate more complex geometries at relatively low
computational costs. The simulations of complex and very fine resolution
computational domains in CFD is challenging due to the lack of memory
resources and long processing times, therefore parallel computing is being
considered as a promising way to cope with this ever increasing mission of
computational power. In this work parallelization of 2-D lattice Boltzmann
model based CFD code using message passing interface was performed to
increase speedup factor for parallel computing. Lattice Boltzmann approach
based CFD code of a benchmark Lid driven cavity flow problem was
parallelized using different message passing interface subroutines and made
to run on a cluster system of processors. The time and speed up factor for
execution of the benchmark problem was investigated. The results showed that
these message passing communications have little influence on the
performance of the parallel lattice Boltzmann method.

Authors: Tolba Ahlam , Ramadan Dina , Almetwally Ehab , Jawa Taghreed , Sayed-Ahmed Neveen
Published: January 2023

The inverse Lomax distribution has been extensively used in many disciplines,
including stochastic modelling, economics, actuarial sciences, and life
testing. It is among the most recognizable lifetime models. The purpose of
this research is to look into a new and important aspect of the inverse
Lomax distribution: the calculation of the fuzzy stress-strength reliability
parameter RF = P(Y < X), as?suming X and Y are random independent variables
that follow the inverse Lomax probability distribution. The properties of
structural for the proposed reliability model are studied along with the
Bayesian estimation methods, maximum product of the spacing and maximum
likelihood. Extensive simulation studies are achieved to explore the
performance of the various estimates. Subsequently, two sets of real data
are considered to highlight the practicability of the model.

In this article, we adopted the classical and Bayesian approach to develop
the problem of estimation and prediction of the inverse Lomax distribution
under Type-I hybrid censored scheme. Firstly, we presented maximum
likelihood estimators and Bayes estimators of the unknown parameters under
consideration of squared error loss equation. In Bayesian approach, we used
Markov chain Monte-Carlo method by applied importance sampling technique.
Asymptotic confidence intervals and Bayes credible intervals are
constructed. The estimators are tested by building sim?ulation study.
Secondly, For given Type-I hybrid censoring sample Bayesian prediction of
future order statistics are formulated (two-sample case). Finally, the
numerical computations are adopted on a real data set for illustrating
purpose.

Authors: Ahmad Imtiaz , Ahsan Muhammad , Elamin Abd , Abdel-Khalek Sayed , Inc Mustafa
Published: January 2023

In this study, we use an effective meshless method to estimate the numerical
solution of 3-D time-fractional Sobolev equation. The recommended meshless
method is used for the spatial derivatives while the Liouville-Caputo
derivative technique is utilized for the time derivative portion of the
model equation. Accuracy of the method is assessed via error norms and
comparison is made with the exact solution and other numerical methods given
in more current literature, which demonstrated that the suggested strategy
produces excellent performance and is more computationally efficient.

Authors: Ahmad Imtiaz , Abdel-Khalek Sayed , Alghamdi Ahmed , Inc Mustafa
Published: January 2023

Numerical solution of the generalized Burger?s-Huxley equation is established
utilizing two effective meshless methods namely: local differential
quadrature method and global method of line. Both the proposed meshless
methods used radial basis functions to discretize space derivatives which
convert the given model equation system of ODE and then we have utilized the
Euler method to get the required numerical solution. Numerical experiments
are carried out to check the efficiency and accuracy of the suggested
meshless methods.

Published: January 2023

In this study, numerical studies to clarify the influence of wave number and
amplitude on thermal-flow behavior of wavy annular finned-and-tube heat
exchangers are described. For a range of Reynolds number from 4400 to
14300, the influence of wave amplitude, 1.5 ? A ? 4.5 mm, and wave numbers,
2 ? Nw ? 6, on forced convection heat transfer was examined. It was revealed
that the wave amplitude and number have an impact on the heat flux, Colburn
factor, and friction factor. The wavy annular-fins with a 3 mm amplitude and
Nw = 4 waves obtained the highest values at all Reynolds numbers in terms of
the overall performance criterion (j/f1/3).

Authors: Zhou Min , Xu Qiuping , Zuo Dong , Wang Zhiyi , Zhang Maohua , Liu Tingting , Liu Renqi
Published: January 2023

Background/Aim. Pericapsular nerve group block (PNGB) does not affect the motor nerve while blocking the obturator and femoral nerves. The aim of the study was to determine the application value of PNGB for hip replacement in the elderly. Methods. Ninety elderly patients who underwent hip replacement from March 2019 to October 2020 were randomly divided into the fascia iliaca compartment block (FICB) group and the PNGB group. FICB and PNGB were performed prior to subarachnoid block (SAB). Their baseline data, operation conditions, incidence of adverse reactions, visual analog scale (VAS) score, heart rate (HR), mean arterial pressure (MAP), plasma cortisol (COR), and epinephrine (E) levels were compared. Results. VAS score, E, and plasma COR levels in the PNGB group were lower than those in the FICB group at time points T2?T4 (T2: 10 min after nerve block; T3: at position changing; T4: after position changing) (p < 0.001). There were no significant differences in HR and MAP between the two groups at any time point (p > 0.05). In the PNGB group, the ultrasonic imaging time was shorter, the time point of pressing patient-controlled analgesia (PCA) for the first time was later, and the numbers of pressing PCA were fewer than those of the FICB group (p < 0.001). No local anesthetic poisoning took place after the nerve block, and no hematoma at the puncture site, nerve injury, nausea and vomiting, dizziness, or delirium occurred. Conclusion. Both FICB and PNGB prior to SAB were highly safe for hip replacement in the elderly; however, PNGB has shorter ultrasonic imaging time, better analgesic effect, and milder oxidative stress, so it is worth applying it clinically.

Published: January 2023

Aspergillus, Penicillium and Talaromyces species are frequently cited as
contaminants of various substrata and are often associated with indoor
environments. The main purpose of this study was to assess the potential
pathogenicity of aerosol-derived fungi from Aspergillus, Penicillium and
Talaromyces genera, isolated in the rooms for con?servation of cultural
heritage artefacts, via estimating hemolytic activity. Hemolysis was
detected in 20.58% of tested isolates at 37?C (11.76% partial and 8.82%
complete) and 64.71% at 25?C (38.24% partial and 26.47% complete). The
majority of isolates that caused ? hemolysis led to the significant
oxidation of hemoglobin iron with methemoglobin content in blood agar
medium, higher than 80%. Aspergillus melleus was the only tested fungi that
caused formation of ferry hemoglobin after the incubation at 25?C. Obtained
I values (index of activity for hemolytic exoenzymes) for ? hemolysis were
in range of from 0.13 to 0.60 for 37?C, while for the temperature of 25?C
values were in range of from 0.08 to 0.50. The same values for ? hemolysis
were in range of from 0.03 to 0.08 (37?C), i.e. 0.06 to 0.49 (25?C).
Monitoring of pathogenic airborne fungi in indoor environments and
estimation of their virulence is essential for the adequate assessment of
human health risks.

Published: January 2023

Bacillus spp. are well known to protect plants from seed or soil-borne
pathogens by the synthesis of various metabolites with antimicrobial
activity, such as hy?drolytic enzymes and antibiotics. This study aimed to
select the most effective Bacillus spp. from a group of ten antagonistic
strains by antifungal activity assay. Bacillus strains were primarily
isolated from the soil and identified as B. safensis, B. pumilus and B.
subtilis by 16S rDNA sequencing. The four analyzed fungi: Macrophomina
phaseolina, Alternaria alternata, Cladosporium cladosporoides, and
Sclerotinia sclerotiorum, were obtained from sunflower seeds and identified
using PCR analysis and primers specific for ITS region. The antifungal
activity of bacterial strains was examined in a dual plate assay. Bacillus
spp. demonstrated the highest antagonism against S. sclerotiorum, followed
by C. cladosporoides, M. phaseolina, and A. alternata, with an average
percentage of growth inhibition (PGI) of 77%, 70%, 64% and 59%,
respectively. Overall, Bacillus spp. included in this study demonstrated a
rather strong biocontrol potential, although the effect of particular strain
varied depending on the tested fungi. The highest antagonistic effect toward
M. phaseolina and A. alternata was exhibited by B. safensis B2 and B.
pumilus B3. B. pumilus B11 and B. subtilis B32 were the most efficient
against C. cladosporoides, whereas B. pumilus B3 and B. subtilis B7 had the
highest antifungal activity against S. sclerotiorum. Findings point to the
fact that the most effective Bacillus spp. could be used as potential
biocontrol agents for improving plant health and productivity.

Authors: Galic Milica , Cilerdzic Jasmina , Stajic Mirjana
Published: January 2023

Nowadays, there are huge amounts of lignocellulosic materials left in agroforestry practice, which can be transformed into useful products. Biomass exploitation could be aiming not only at replacing conventional energy sources but also at preserving biodiversity and natural ecosystems. Five micromycetes were studied with goal to determine their potential to produce active cellulases as well as the ability to decompose pretreated wheat straw and oak sawdust after seven days of solid-state fermentation. Wheat straw was better lignocellulosic substrate than oak sawdust for the production of cellulases in all five micromycetes. Thus, Penicillium solitum BEOFB 1190m has shown to be the best producer of highly active forms of xylanases (7532.36 ? 89.37 U/L). The most active endo- and exocellulases (2299.70 ? 72.17 U/L and 195.66 ? 4.64 U/L, respectively) were produced by Trichoderma harzianum BEOFB 1230m, while the maximal value of ?-glucosidase activity (215.69 ? 3.13 U/L) was detected after Fusarium graminearum BEOFB 820m cultivation. T. harzianum also showed high efficiency in wheat straw cellulose and hemicellulose depolymerization (23.90% and 33.00%, respectively), which resulted in the highest dry matter loss (36.25%). The results of the study showed great potential of tested micromycetes to synthesize cellulolytic enzymes and consequently transform abundant, low-cost plant residues such as wheat straw into useful products including biofuel.

Authors: Borges JS , Soares CJ , de Bragança GF , Vilela ABF , Soares PBF
Published: January 2023

Objective

This study aimed to evaluate the effect of activated charcoal toothpaste on the color stability of teeth subjected to tooth bleaching and pigmenting agents.

Methods

A total of 120 bovine crowns were randomly divided into 12 groups (n=10) according to two study factors: staining solutions (three levels): saliva (control), coffee, and red wine; and toothpaste (four levels): BPC, Bianco Pro Clinical (Bianco Oral Care) (Control); BIW, Black is White (Curaprox); BCA, Bianco Carbon (Bianco Oral Care); and NAT, Natural Suavetex (Suavetex). The samples were subjected to office bleaching with a 35% hydrogen peroxide-based gel (Whiteness HP Blue, FGM), followed by immersion in the solution for 45 minutes per day and daily toothbrushing for 7 days. The color (ΔE) and luminosity changes (ΔL*) were measured using reflectance spectroscopy (Vita EasyShade). The CIE values (L*, a*, b*) were measured at baseline after bleaching (T0) and immediately after immersion in solution each day (Ti1–Ti7) and after all toothbrushing cycles (Tb1–Tb7). ΔE and ΔL were analyzed using a two-way analysis of variance and Tukey’s test (α=0.05). The clinically unacceptable level of ΔE > 3.3 was used to evaluate the color change.

Results

The color change was significantly influenced by the staining solutions and toothpastes (p<0.001). The color change (ΔE) was significantly higher when immersed in wine than in coffee, and lower ΔE values were observed for artificial saliva (control), irrespective of the toothpaste used. In artificial saliva, BPC, BIW, and BCA resulted in significantly lower ΔE values than NAT, which presented a clinically unacceptable level of dental color change (ΔE>3.3). Coffee resulted in a lower (L*) reduction than wine, irrespective of the toothpaste used.

Conclusion

Charcoal toothpastes resulted in a color change on the surface of the tooth enamel (ΔE). The bleaching effect of the charcoal toothpastes and control evaluated in this study partially reduced the color changes on the surface of the tooth enamel caused by staining solutions but was unable to reestablish the measured values to the baseline. For teeth immersed in artificial saliva, the color change was not noticeable in BCA, BIW, and control-BPC (ΔE≥3.3), except for NAT, which showed a significant color change.

Published: January 2023

This study aimed to compare the fracture toughness of molars with wide mesio-occlusal-distal (MOD) cavities restored with regular and flowable bulk-fill resin composite and a conventional resin composite after 250,000 mechanical cycles of chewing simulation. Thirty-two extracted mandibular third molars were selected and class II MOD cavities involving 2/3 of the intercuspal width and 4 mm depth were prepared. Teeth were divided into four groups based on resin composite type and insertion technique (n=8): (1) CT, unprepared teeth (control); (2) CV, conventional resin composite (Tetric N-Ceram, Ivoclar Vivadent) with incremental technique; (3) R-BF, regular bulk-fill resin composite (Tetric N-Ceram Bulk Fill, Ivoclar Vivadent) with a single increment; and (4) F-BF, flowable bulk-fill resin composite (Tetric N-Flow Bulk Fill, Ivoclar Vivadent) with a single increment, except for a 1-mm-thick layer at the occlusal surface, restored with conventional resin composite (Tetric N-Ceram). All specimens were evaluated to detect the presence and propagation of enamel cracks using a LED transilluminator before and after 250,000 mechanical cycles (SD Mechatronic GmbH). After a chewing simulation, they were subjected to a compressive force in a universal testing machine (DL-2000, EMIC) until fracture. The maximum fracture load of the specimens was measured (N) and the fracture patterns were classified based on the fracture site (above or below the cementoenamel junction [CEJ]). Data were statistically analyzed with one-way ANOVA. All specimens survived after 250,000 mechanical cycles, and no statistically significant differences among groups were observed regarding the fracture toughness (p<0.05). The fracture analysis demonstrated that failures below the CEJ were more common in CV (75%), while CT, R-BF, and F-BF showed this type of failure in 38%, 63%, and 63% of the specimens, respectively. The results of the crack analysis showed that the occurrence of new cracks and crack propagation was also higher in CV (33.3%), followed by R-BF, F-BF, and CT (14%, 14%, and 11% of the specimens, respectively). Teeth restored with regular and flowable bulk-fill composites showed similar fracture toughness after the chewing simulation compared to those restored with the conventional resin composite and unprepared teeth. Furthermore, teeth restored with both regular and flowable bulk-fill composites showed a lower incidence of enamel cracks and fractures below the CEJ compared to those restored with the conventional resin composite.

No artigo apresento a composição de um acervo literário disponibilizado a um projeto de leitura para adolescentes escolarizadas, cujo foco é discutir maus tratos emocionais ou violência psicológica. Ao criar um programa de leituras para meninas em que a liberdade para pensar e escolher fosse o meio e o fim, reuni um grupo de livros que têm em comum, temas ou protagonistas meninas, mocinhas ou mulheres que extrapolam os clássicos papéis destinados culturalmente ao gênero feminino. Na construção dessas personagens e tramas, os autores e autoras apresentam desfechos inusitados, inteligentes, bem humorados, afetivamente includentes e com lógicas não violentas. No trabalho, apresento o acervo produzido por esse trabalho de pesquisa e intervenção. Os maus tratos emocionais são um fenômeno caracterizado por um constante e reiterado desrespeito ao outro. Muitas vezes sutil, se manifesta pelo desprezo, desqualificação ou depreciação de gostos, escolhas e competências, através de falas, comentários ou mesmo argumentações que ridicularizam, desabonam e desacreditam a imagem do outro de forma direta ou indireta, publicamente, na presença e mesmo na ausência do envolvido. É uma violência que, em parte considerável das vezes, abre portas para outras manifestações e formas de violência como violência física, moral, patrimonial, sexual. Na elaboração desse "conceito", busquei conhecer pesquisas, artigos e palestras desenvolvidas por pesquisadores na área.
limites no apreço pela cosmovisão

Published: January 2023

O presente estudo tem como objetivo traçar uma crítica ao sentido de apreço pela cosmovisão ocidental, através de reflexões acerca de cosmogonia, semântica cultural da beleza e do mito e da relação desses a partir da análise dos mitos de Oxum, divindade iorubana, também cultuada no Brasil, e Afrodite, divindade grega, que costuma compor os currículos escolares como referência ao mundo antigo, ou a sociedades politeístas, as quais são um tabu no atual mundo cristão ou cristianizado. Concluímos, portanto, no sentido de apresentar o processo estruturalmente racista de tentativa de apagamento das culturas africanas no contexto brasileiro, tendo como inferiores divindades negras-africanas e supervalorizando a cultura ocidental, inclusive suas divindades brancas, haja vista a valorização da visão no ocidente e a valorização do holístico.

Published: January 2023

Este estudo tem como objetivo apresentar o iconotexto em correlação com o ethos prévio e com o ethos discursivo existentes na capa do livro Sobrevivendo no Inferno do grupo de rap paulista Racionais Mc’s. Desse modo, tomamos como discussão os postulados da análise de discurso de linha francesa, basicamente as ideias de Maingueneau (2020) e também as reflexões da imagem que o enunciador constrói de si, da Amossy (2016). Além das contribuições de Mariano (2014, 2020) para os estudos do ethos. Assim, consideramos que o iconotexto enquanto indissociação do visual/verbal também é inseparável do ethos prévio e do ethos mostrado/dito na materialidade analisada.

Este artigo é parte da tese intitulada "Juventudes e Deficiência: Narrativas Autobiográficas de Jovens Mulheres" que está sendo produzida no Programa de Pós-graduação em Educação na Universidade Federal do Rio Grande do Sul. Ao abordar o tema das juventudes, o argumento procura desnaturalizar ideias e concepções correntes. Assim, o conceito é afastado tanto do singular, juventude, como do termo adolescência, considerado, em muitos estudos seu sinônimo. Juventudes, no plural, também se justifica no reconhecimento da existência de múltiplas experiências juvenis. Este artigo ancora-se na sociologia da juventude. Dialoga-se com autores como Luís Antônio Groppo (2016, 2017) a fim de historicizar distintas concepções; Karl Mannheim (1993 [1928]); Marialice Foracchi (1972) em se tratando de geração; e pesquisadores como Mário Margulis e Marcelo Urresti (2000); Silvana Goellner (2003) no que envolve as moratórias social e vital, enfatizando, nesta última, questões relativas ao gênero e ao corpo.

Os anúncios publicitários são formas de comunicação de massa. Um anúncio impresso tem o potencial de atingir milhares de pessoas. Por outro lado, pesquisas sobre comunicação de massa têm demonstrado como um único anúncio se abre a diferentes interpretações. O objetivo deste artigo é analisar anúncios publicitários veiculados em revistas impressas brasileiras pelo viés da Análise Crítica do Discurso, enfatizando aspectos relacionadas aos discursos públicos na modernidade tardia, como a mercantilização da linguagem, a hibridez discursiva e a relação entre os elementos linguísticos e imagéticos na busca de persuadir os consumidores. Para tanto, utilizo as concepções de Chouliaraki e Fairclough (1999), a Gramática do Design Visual, de Kress e van Leeuwen (2006) e pesquisadores que lidam com a linguagem publicitária e sua função persuasiva. Os resultados indicam que a mercantilização da linguagem e a hibridez apresentada nos anúncios analisados configuram-se como importantes estratégias persuasivas usadas pelos produtores dos anúncios na busca de venderem seus produtos.
Surface Urban Heat Island In Moscow During The COID-19 Pandemic Lockdown In 2020
Authors: Lokoshchenko Mikhail A. , Enukova Eugeniya A.
Published: January 2023

The influence of the COronaVIrus Disease 2019 (COVID-19) pandemic lockdown (the period of strict quarantine measures) in the spring of 2020 on the ‘Surface Urban Heat Island’ (SUHI) geographical phenomenon in Moscow has been studied. For this purpose, we used the measurements of the surface temperature TS made by Moderate Resolution Imaging Spectroradiometer (MODIS) radiometer installed on Terra and Aqua satellites. As a result, TS during the 2020 lockdown, both in the city and surrounding rural zone, was found lower than at the same calendar time in the previous 20 years due to the relatively cold spring. The SUHI intensity as the difference between TS inside Moscow and the surrounding rural zone around it during the lockdown was also lower than usual (on average in the previous 20 years), but this decrease is relatively small and nonsignificant. The Normalized Difference Vegetation Index (NDVI) in Moscow and Moscow region during the lockdown was close to its usual values, but the leaf area index (LAI) was significantly lower than its average values in the previous 20 years. Thus, the weakening of the SUHI during the lockdown in 2020 was caused mostly by lower heat loss due to transpiration in the rural zone. This was associated with the slowdown in vegetation development as a result of the cold spring. Besides, an additional possible reason was the reduction of human activity due to the collapse of many anthropogenic heat sources in the city. According to long-term MODIS data, the SUHI intensity in Moscow and the surface temperature in Moscow region, as well as the NDVI and LAI values, do not demonstrate statistically significant long-term trends in the spring season over the past 21 years, despite climate changes. In spring, during faster snow melting in cities, when it still persists in the rural zone, the SUHI intensity can be record high (up to 8 ºC).

Authors: Hanif Aysha , Shirazi Safdar A. , Jabbar Muhammad , Liaqat Anum , Zia Sahar , Yusoff Mariney M.
Published: January 2023

Ecosystem services provided by urban parks play a significant role in visitors’ well-being. The provision of these services depends upon the well-designed green spaces built to fulfil the needs of people. As these services are linked with visitors’ well-being, particular emphasis to indicate them is needed. However, minimal documentation is found regarding these valuable services, particularly in the context of Lahore. So, in this study, an effort was made to highlight visitors’ preferences for the available ecosystem services provided by urban parks in Lahore, Pakistan. These ecosystem services are beneficial in enhancing the well-being of people. Fifteen parks in Lahore were selected in this study to highlight the visitors’ preferences in visiting the parks. A questionnaire-based survey was conducted in these parks to collect information. The questionnaire was compiled to record socio-demographical profiles, usage patterns, choices, and visitors’ opinions about the services provided by the parks. A total of 300 responses were recorded to depict the survey findings. The result highlights that 60-80% of visitors like to come to the parks having maximum services regardless of how distant is from their residence. It also reveals that large-sized parks with maximum facilities attract more visitors than small and medium-sized parks. As in these parks, people only from neighbouring areas visit due to their accessibility. The findings will be helpful for the managers and planners of the urban park to improve the ecosystem services for the well-being of people. It will also indicate the choices of people based on that information, the status of parks can be improved, and new parks can be developed to meet the visitors’ needs.
Climate-Related Gradients On Vegetation Diversity Of The Altai-Sayan Orobiome (Southern Siberia)
Authors: Bocharnikov Maxim V.
Published: January 2023

An analysis of the spatial organization of vegetation cover has been carried out for the Altai-Sayan orobiome in connection with climatic conditions in the Southern Siberian mountains based on original relevés of plant communities at the 4 altitudinal spectra. Basic bioclimatic parameters on the altitudinal spectra of vegetation have been determined according to latitudinal and longitudinal differentiation of climate. Correlation and discriminate analyses allowed to identify the regional features of altitudinal gradients in species diversity of the spectra as well as the role of parameters in the structure of typological diversity of vegetation for belts of high-mountain tundra, alpine and subalpine meadows and sparse forests, dark coniferous mountain taiga forests, chern-taiga forests, small leave – light coniferous subtaiga forests, forest-steppe. A compiled bioclimatic scheme characterizes the spatial organization of orobiome’s vegetation by basic bioclimatic parameters on the regional level (continentality index, average temperature of January). This scheme shows regional features of the diversity of vegetation in Southern Siberia, in adjacent plain and mountain regions according to climatic conditions. Identified patterns determine unity of the Altai-Sayan orobiome as well as regional differentiation that reflected on the development of types of vegetation zonality. They can be used to analysis of vegetation forming in different mountain systems.
Contribution Of The Different Sources To The Formation Of Alluvial Sediments In The Selenga River Delta. (Eastern Siberia, Russia)
Authors: Zaharova Ellina D. , Belyaev Vladimir R.
Published: January 2023

Unraveling sources of sediment supply, their temporal and spatial variability is of key importance to determine origin of deposits and to explore the formation mechanism of Selenga Delta landscape units. From an environmental point of view this solution would help to identify the particle-bound pollution sources. We used geochemical fingerprinting (the FingerPro R package), which is a modern quantitative implementation of the method of sedimentary provenance analysis. The main aim was to recognize the main patterns of sediment and associated particle-bound pollutants transport and deposition within the delta. At the old floodplain from 55% to 90% of sediments were delivered from the eroded floodplain and terrace banks upstream and only about 10-15% originates from the remote basin sources. Sedimentary environment in the Khlystov Zaton reveals a greater variety than on the floodplains. 40% of sediments from the upper 5 cm-layer originated from the flood, taking place in 2013, and 30% were the product of floodplain and terraces banks erosion. Nevertheless, analysis of the fine-grained component of suspended sediment sets the material from eroded floodplain banks as the dominant source of accumulation within the delta. This means that the self-absorption is the leading process in the Selenga delta at the moment. Heavy metals and metalloids accumulates in the lower reaches of the Selenga on the floodplain surface, deltaic lakes and oxbows during high floods. Runoff decrease during floods can lead to the release of pollutants into the Lake Baikal.

Forrest Gump’s Contribution to Research Methodology: An Analogy for Organizational Culture and Some Musings on How to Write about Comparisons
Authors: Racine Michel , Gould Anthony M.
Published: January 2023

When the fictional character Forrest Gump said: “Life is like a box of chocolates,” he offered an intriguing insight into at least one aspect of human existence. However, in creating his analogy he likely fell into a trap that sometimes ensnares social science researchers. For example, since the 1950s authors in disparate academic and professional genres have used metaphors/analogies to better understand organizational culture and create imagery encapsulating its key components. However, this essay argues that this genre is not always associated with methodological rigor. Problems include: metaphors/analogies are often employed without associated rationale; and, authors define their object of analysis in overly broad ways and/or fail to specify an agenda. This article explores these limitations in their historical context and offers a strategy for remedying them, a strategy with implications for scholarly written communication. Identified problems and a proposed solution are somewhat generic and are therefore relevant wherever analogies are used.

Dengan metode kualitatif dan studi pustaka, penulis mendeskripsikan pemahaman yang dapat diambil dari hadits ini. Berdasarkan hasil penelitian ditemukan bahwa banyak perbedaan pendapat dalam rincian akad hawalah. Kemudian ditemukan juga bahwa salah satu hadits yang dijadikan rujukan tidak memiliki derajat shohih dan hadits tersebut juga tidak mengarah langsung pada akad hawalah.

Henoch-Schonlein purpura (HSP) is the most common vasculitis in childhood and is clinically characterised by purpura, abdominal pain, arthritis and renal involvement. Scarcely, some patients with HSP may not always show visible rash and can present with insidious abdominal symptoms. We present two patients: an 8-year-old boy who was initially considered as having infectious diarrhoea and mesenteric lymphadenitis, then intussusception, appendicitis, appendicopathia oxyuriaca and post-operative ileus. However, he was finally diagnosed with HSP, as the typical rash appeared 10 days after onset of abdominal symptoms. The second patient was a 5-year-old boy with recurrent vomiting, abdominal pain and mild dehydration, where swollen joints and typical rash appeared on day 3. Both patients were successfully managed with orally administered corticosteroids. The patients did not have any further consequences of HSP.

Authors: Belmonte Martínez Isabel María
Published: January 2023

El presente artículo comienza poniendo de manifiesto la importancia que el conocimiento y el aprendizaje tienen en el contexto actual para hacer frente a los enormes retos a los que nos enfrentamos como sociedad. Se hace un especial énfasis en el impacto que la COVID-19 ha supuesto a todos los niveles, especialmente en lo que a la cuestión de género se refiere, y el retroceso que se ha sufrido en esta materia como consecuencia de la pandemia, al mismo tiempo que se destaca la importancia de aquélla como factor de crecimiento.
A continuación se describen las principales estrategias y políticas públicas existentes a nivel europeo de cara a la consecución de la igualdad de género. Seguidamente se analizan las principales manifestaciones que el principio de igualdad tiene en el sector público (estatal y autonómico) con el fin de comprobar si realmente dicha igualdad es una realidad o una aspiración cuya consecución se torna necesaria si queremos conseguir una sociedad más inteligente, sostenible e integradora.
Para finalizar se analiza el papel que la educación y el aprendizaje tienen en la consecución del principio de igualdad, haciendo una especial mención al aprendizaje de mujeres y niñas en las carreras STEM como una de las principales herramientas para hacer frente a los grandes retos y desafíos que se nos plantearán en el presente y en el futuro a la humanidad.
