Lost in hybridity? About dilemmas endangering meaningful tourism education at German universities of applied sciences
Authors: Rundshagen Volker , Gronau Werner
Published: February 2022

The contribution at hand sheds light on dramatically mounting tensions that academic tourism education in Germany is facing within the context of applied science universities. Drawing on the concept of organizational hybridity, we distil two dilemmas resulting from respectively incongruent expectation sets. Firstly, aspatial hybridity dilemmaresults from opposing missions of regional development and embeddedness versus internationalization prescriptions and efforts. Secondly, there is anideational hybridity dilemmaresulting from imperatives to serve employment markets versus academic purposes of serving social and scientific ideals. Based on a tourism program case from Northern Germany we highlight how a mélange of diverse, partly obscure and increasingly conflicting missions as well as largely inflated and for the most part incongruent stakeholder expectations threaten to tear the institution apart and to lead tourism education onto pathways where it could lose its bearings. We summarize our three major concerns of academicsdrifting off the course of integrityout of desperation resulting from overwhelming pressures,impoverished learning experiencefor our student constituencies andimpoverishment of researchin an era where we need meaningful research more than ever in tourism and beyond. We thus contribute to the debate about the future of tourism education in academia.
Review: Atopic Dermatitis - Exposome, Microbiome, Psyche,and Evolution
Authors: Penev Julian , Balabanova Milla , Bakardzhiev Ilko
Published: February 2022

Atopic Dermatitis (AD) is probably the most common type of eczema. The quality of life assessment reveals a number of negative consequences for patients with AD and their families. AD is associated with high levels of stress, stigma, social withdrawal, anxiety, depression, and even suicide ideation. Atopic dermatitis is a multisystem inflammatory disease with a multifactorial, and still controversial etiology. Complex interactions between genetic, psychoneuroimmune and endocrine factors, microbiome, exposome and environment, mental and social factors, diet and lifestyle are proposed. AD is difficult to treat, has a chronic course with peaks of exacerbation and pronounced manifestation of mental factors. Such complexity requires deeper understanding of mechanisms behind AD. We consider a possible psychogenic component in diseaseexacerbation, andoffera different point of view onrelationships of human body with the colonizing microbiomein the context of AD etiology and pathogenesis. These relationships are interpreted in evolutionary terms in an attempt to shed some light on mechanisms of chronic and pathological skin processes.

Pepper and Garlic Extracts as an Alternative Treatment to Onychomycosis: AMyth or Truth?
Authors: Chen Hsuan-Hsiang
Published: February 2022

Onychomycosis is a chronic disease ofa nail infection by the fungi. Based on the mode of nail invasion and morphologic patterns, it can be divided into 5subtypes: distal and lateral subungualonychomycosis, proximal subungualonychomycosis, superficial onychomycosis, total dystrophic onychomycosis, and endonyxsubungualonychomycosis.Common pathogens are dermatophytes, non-dermatophyte molds, and yeasts. In recent years, the development of new antifungal agents, such as allylamines and azoles, has provided good treatment options for onychomycosistherapy. There is a growing interest in the use of plant-derived compounds or alternatives to treat dermatophyte infection. Recently, a Chinese web page describing an alternative method for onychomycosis by using garlic and pepper extractswas very popular [Figure 1] [1]. They described 200 cases of onychomycosis patients treated once daily with a mixture of 100g garlic and 20g pepper extracted with 500ml acetic acid for 30 days. They claimed the cure rate was 94.05% and the effective rate was 99.88%. Although it may seem effective, the detailed exact preparation methods, the culture results, and the subtypes of the onychomycosis were not described. The treatment responses also seemed too good to be true. Martin et al. reviewed 7 controlled clinical trials performed to determine the effectiveness of plant extracts against fungal infection [2]. Among them, tea tree oil was the most thoroughly clinically tested. Solanum species and oil of bitter orange preparations were also reviewed. However, there were no researches on garlic or pepper preparation. Till now, there are still no peer-reviewed, double-blind, placebo-controlledclinical trials of garlic or pepper-based preparations used as an alternative treatment method for onychomycosis.

Introduction: Deep subcutaneous mycosis results from the involvement of subcutaneous tissue by microscopic fungi. Few studies have been conducted on these diseases in Benin. Patients and methods: This was a retrospective descriptive study that included all cases of subcutaneous mycosis recorded in the Dermatology-Venerology Department of the CNHU-HKM from 2009 to 2020. Results: 3 cases of deep subcutaneous mycosis were recorded in 12 years, including two cases of basidiobolomycosis and one case of fungal mycetoma. The cases of basidiobolomycosis were observed in two girls aged 7 and 8 years whose lesions were located on the right buttock, in the form of indurated placards, adherent to the superficial plane, measuring respectively 10cm by 5cm and 14cm by 7cm. Mycological examination of the biopsy specimens isolated Basidiobolus ranarum. The only case of fungal mycetoma was observed in a 39-year-old man, in the form of a nodular placard measuring 14cm by 12cm, polyfistulised, inflammatory and squamous-crusty with an irregular border that had been evolving for 15 years. Mycological examination of the pus revealed the presence of black grains and the identification of Madurella mycetomatis. Treatment with Ketoconazole was initiated in all three patients but the evolution could not be appreciated. Conclusion : Subcutaneous mycosis is rare in Cotonou, but probably underestimated.

Published: February 2022

Many studies have examined the vulnerability of calcifying organisms, such as the eastern oyster (Crassostrea virginica), to externally forced ocean acidification, but the opposite interaction whereby oysters alter their local carbonate conditions has received far less attention. We present an exploratory model for isolating the impact that net calcification and respiration of aquacultured eastern oysters can have on calcite and aragonite saturation states, in the context of varying temperature, ocean-estuary mixing, and air-sea gas exchange. We apply the model to the Damariscotta River Estuary in Maine which has experienced rapid expansion of oyster aquaculture in the last decade. Our model uses oyster shell growth over the summer season and a previously derived relationship between net calcification and respiration to quantify impacts of net oyster calcification and gross metabolism on carbonate saturation states in open tidal waters. Under 2018 industry size and climate conditions, we estimate that oysters can lower carbonate saturation states by up to 5% (i.e., 0.17 and 0.11 units on calcite and aragonite saturation states, respectively) per day in late summer, with an average of 3% over the growing season. Perturbations from temperature and air-sea exchange are similar in magnitude. Under 2050 climate conditions and 2018 industry size, calcite saturation state will decrease by up to an additional 0.54 units. If the industry expands 3-fold by 2050, the calcite and aragonite saturation states may decrease by 0.73 and 0.47 units, respectively, on average for the latter half of the growing season when compared to 2018 climate conditions and industry size. Collectively, our results indicate that dense aggregations of oysters can have a significant role on estuarine carbonate chemistry.
Controller-Einbindung in die Strategieentwicklung
Authors: Hiebl Martin R.W. , Pielsticker David I.
Published: February 2022

Bislang deuten vor allem qualitative Forschungsarbeiten an, dass Controller in den letzten Jahren verstärkt in die Strategieentwicklung verschiedener Organisationen eingebunden werden. Dies scheint insbesondere dann der Fall zu sein, wenn Topmanager eine derartige Einbindung fördern. Gleichzeitig bestehen nur wenige großzahlige empirische Studien zu den Treibern der Controlling-Einbindung in die Strategieentwicklung. Vor diesem Hintergrund untersuchen wir in diesem Beitrag, welcher Führungsstil des Topmanagements die Einbindung der Controller in die Strategieentwicklung begünstigt. Unsere Ergebnisse zeigen, dass unter Topmanagern mit einem eher transformationalen Führungsstil Controller stärker in die Strategieentwicklung eingebunden sind, während ein eher transaktionaler Führungsstil die Controller-Einbindung nicht zu begünstigen scheint.
The effect of hemicellulose content on mechanical strength, thermal stability, and water resistance of cellulose-rich fiber material from poplar
Authors: Wang Quanliang , Xiao Shengling , Shi Sheldon Q.
Published: February 2022

The hemicellulose content of cellulosic material from poplar chemi-thermomechanical pulp (CTMP) was controlled by a microwave-assisted formic acid (MFA) extraction process. The environmentally friendly, self-bonded, and cellulose-rich fiber sheets (around 0.3 mm thick and 280 g/m2 grammage) were fabricated via a molding and compression process. The results showed that the MFA treatment effectively controlled the hemicellulose content in the range from 6.8% to 20.4%. Mechanical testing results showed a good linear relationship between the tensile strength and the hemicellulose content, where a higher hemicellulose content obtained a stronger tensile strength. Meanwhile, as hemicellulose content decreased, the onset temperature, representing the thermal stability, increased from 318.1 °C to 335.7 °C and the elastic modulus, representing the mechanical stiffness, increased from 0.047 MPa to 0.068 MPa. Additionally, as the hemicellulose content decreased, the water-resistance of the cellulose-rich fiber sheets improved. During the hemicellulose removal process, the strength of single fibers was found to have a dominant role in the mechanical strength of the cellulose-rich fiber sheets, rather than the inter-fiber bonding strength. This was contrary to research on the delignification process, where the inter-fiber bonding strength was found to be more important than the strength of single fibers in deciding the material strength.
The Crisis of the Political. Polis and an Individual
Authors: Kazlauskas Raimondas
Published: February 2022

The article discusses the crisis of the political, treating this phenomenon as an interactive constellation of political, over-political and apolitical factors. The aim is to reconstruct the assumptions of the crisis and highlight its main features in the context of ancient Greece. Under the influence of Dionysian religion, theater was established as a compelling and universally accessible authority to legitimize democracy. Therefore my analysis focuses on the social change after which democracy was no longer perceived as a form of governance but as a form of collective ownership. The article explains how the unbridled demonstration of power quickly erased the long-cherished principle of verbal argumentation and pushed Greeks to practice of power politics. It is shown how, with the establishment of autocracy, parallel interchange between political and anti-political institutions emerged in the Greek polis.

Published: February 2022

OBJECTIVES

Dexamethasone is increasingly used for the management of children hospitalized with asthma in place of prednisone, yet data regarding the effectiveness of dexamethasone in children with asthma exacerbation severe enough to require hospitalization are limited. Our objective is to compare the effectiveness of dexamethasone versus prednisone in children hospitalized with an asthma exacerbation on 30-day reutilization.

METHODS

We conducted a retrospective cohort study at an urban, quaternary children’s hospital of children aged 4 to 17 years, hospitalized from January 1, 2014 to December 31, 2017, with a primary discharge diagnosis of asthma. A covariate-balanced propensity score was derived to account for physician discretion in steroid selection. A generalized linear model, including inverse probability treatment weighting, was used to detect differences in 30-day return utilization (unplanned readmission or emergency department visit) between children whose first dose of corticosteroid was dexamethasone versus prednisone.

RESULTS

Inclusion criteria were met by 1161 patients, of which 510 (44%) first received dexamethasone versus 651 (56%) who first received prednisone. The total cohort had a mean age of 8.5 years (SD 3.4). The covariate-balanced cohort had no significant differences in demographic characteristics or illness severity between groups. The dexamethasone group had a return utilization of 3.9% (20 of 510) versus 2.2% (14 of 651) for children treated with prednisone. The propensity score-adjusted analysis revealed the steroid treatment was not found to significantly affect the 30-day reutilization (adjusted odds ratio [aOR] 1.61; 95%CI 0.80–3.31).

CONCLUSIONS

The initial steroid choice (dexamethasone versus prednisone) was not associated with 30-day reutilization after hospitalization for an asthma exacerbation.
Family Psychosocial Assets, Child Behavioral Regulation, and Obesity
Authors: Rollins Brandi Y. , Francis Lori A. , Riggs Nathaniel R.
Published: February 2022

BACKGROUND AND OBJECTIVES

Little attention has been given to the study of early childhood factors that protect against the development of obesity and severe obesity. We investigated whether exposure to familial psychosocial assets and risks in infancy (1–15 months) and early childhood (24–54 months) and child behavioral regulation in early childhood predict longitudinal change in BMI (2 to 15 years).

METHODS

Participants included 1077 predominantly non-Hispanic, White, English-speaking mother-child dyads from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development dataset. Cumulative familial asset and risk indices were created using measures (eg, maternal parenting sensitivity, poverty) from 2 developmental periods (1–15 months, 24–54 months). A child behavioral regulation index was created on the basis of behavioral tasks and parent reports. Previously published BMI trajectories (nonoverweight [40th percentile], nonoverweight [70th percentile], overweight/obese, severely obese) were used as the outcome.

RESULTS

All indices predicted membership in the overweight/obese trajectory; however, when entered into the same model, only familial assets continued to reduce the odds of membership in this trajectory. Familial assets and child behavioral regulation independently reduced the odds of membership in the severely obese trajectory. Furthermore, child behavioral regulation and familial assets buffered the negative effects of familial risk on BMI trajectory membership.

CONCLUSIONS

Early exposure to familial assets and child behavioral regulation may have long-term protective effects on weight gain over early exposure to some familial risk factors (eg, poverty); thus, these indices may help foster obesity resilience.

Published: February 2022

In the context of the geological disposal of vitrified radioactive waste, cracks are expected at the full scale of the glass blocks. To simulate glass alteration in cracks, static dissolution experiments were conducted with confined SM539 glass powder, at 30 °C in a synthetic young cementitious water. Short and long-term glass dissolution rates were determined and compared with those measured in similar experiments with dispersed glass powder. A long-term rate ~ 10 times lower was found, which might be due to a limited access of the solution to the glass surface area, resulting in a much higher local SA/V and faster increase of local concentrations of leached glass constituents, with possibly a lower local pH. In both types of experiments, the altered glass powder was characterised by XRD and SEM-EDX. Some glass particles showed the presence of an amorphous multi-layer and of fibrous and spherical secondary phases.

Published: February 2022

Code-switching (CS) is a natural sociolinguistic phenomenon in bilingualism. This study investigated the attitudes of young and middle-aged Kannada–English-speaking adults towards CS. A total of 254 participants (143 young and 111 middle-aged) participated in this online survey. The survey included four components: demographic characteristics, proficiency, attitude and sentence acceptability task. Further, the study examined the relationship between age, proficiency, acceptability judgments and attitudes toward code-switching. Frequency analyses estimated the number and percentage of occurrences of the categorical variables. Chi-square test of association assessed the relationship between sociolinguistic variables such as age and language proficiency. Results revealed that participants generally had a positive attitude towards code-switching. The effects of age on attitudes towards CS are discussed. Overall, the study intended to draw insights regarding attitudes towards CS in India.
Reaction times to morphologically inflected nonwords
Authors: Cilibrasi Luca , Jiránková Lucie
Published: February 2022

Previous work has shown that monolingual speakers of English are sensitive to the presence of inflectional morphology when it is applied to nonwords. For example, when a nonword ends in a sequence of phonemes that respect the morphophonological rules regulating tense inflection, speakers are slower in recognising it. In this study, we investigated whether a similar pattern applies to second language learners as well. 91 learners of English with Czech as L1 where presented with a same/different minimal pairs task containing nonwords with various endings (in one condition, a sequence of phonemes that could be interpreted as an inflectional morpheme). Consistently with research on monolingual participants, the study showed that also second language learners are slower in processing nonwords that contain potential inflectional morphemes. The pattern was observed from low levels of proficiency, suggesting that learners are sensitive to these rules from early stages of learning.
Popular children’s songs and the display of Italian multilingualism in Australia
Authors: Santello Marco
Published: February 2022

Italians in Australia have been shown to have a varied linguistic repertoire, due to the presence of a high number of regional languages/dialects spoken in Italy, which they brought with them upon migration. Yet, their own efforts to bring attention to their multilingualism have not been fully explored. This article examines an audiocassette recording of a collection of children’s songs produced at the end of the 1970s by an Italo-Australian association for local circulation. It focuses on the design of the audiocassette cover and the range of regional languages/dialects of the songs in the collection, showing how (often mixed-language) texts and images aid language display. The results bring to the surface a deliberate effort to shed light on the rich multilingualism of Italy, which is consistent with the changing role of community languages in the period when this audiocassette was produced. These Italians in Australia make visible their multilingualism, presenting a range of regional languages/dialects also through their use in traditional songs, thereby showing another way in which multilingualism can be acknowledged and valued.
Adolescent test-taker characteristics
Authors: Cheong Yun-Yee
Published: February 2022

This qualitative validation study investigates the characteristics and needs of adolescent test-takers sitting the reading paper of the Singapore-Cambridge General Certificate of Education Ordinary-Level Chinese Language Examination (GCE 1160). Specifically, evidence gathered through semi-structured interview and document analysis was organised around the following three issues: adolescence and adolescent literacy; reading motivation, interests and authenticity; and new technologies and reading literacy. Findings from the analysis suggest that Singaporean adolescents are generally becoming less motivated to read extensively in the Chinese language, seemingly the direct result of digital technologies and heavy homework loads. It also appeared that motivation to read is connected to the relevance and appeal of texts available as well as the perceived value of reading in securing better education and job opportunities. Another pattern illustrated by the study was that the internet is the defining technology for literacy and learning for Singaporean adolescents. Whilst evidence suggested that the GCE 1160 reading examination is designed with adequate knowledge of adolescence and adolescent literacy, several threats to validity were identified, including the relatively low appeal of the passages to test-takers, and their relevance, authenticity and sensitivity to new technologies and reading literacy. Drawing on a socio-cognitive validation framework, the study analyses these threats to validity and outlines practical directions whereby policy-makers and test designers might develop the reading examination.
Poder divino y libertad creada en la modernidad temprana
Authors: Torrijos-Castrillejo David
Published: February 2022

El artículo reflexiona sobre el recelo moderno respecto de Dios como amenaza para la libertad humana. La doctrina sobre la relación entre la libertad y la gracia sostenida por el teólogo español Luis de Molina presenta algunos rasgos que podrían estar emparentados con dicho recelo. La providencia divina resulta salvada en su sistema mediante una concepción algo determinista de la psique humana. Así, no se preserva del todo la libertad, pero, sin embargo, se introduce cierta sospecha respecto del poder de Dios. El autor propone empero una reflexión tomista como una alternativa para contemplar la relación entre Dios y hombre en armonía.

Authors: Calonge-Miranda Adrián
Published: February 2022

El valle medio del Ebro se configuró en época romana como una zona dinámica que tenía unas conexiones terrestres y fluviales. Se desarrolló un conglomerado de ciudades donde predominaban las de pequeño tamaño junto con casos como los de Pompaelo (Pamplona, Navarra) y Caesaraugusta (Zaragoza, Aragón) que contaban con un tamaño mayor. Gracias al avance de la investigación en las entidades urbanas, se puede ubicar el lugar donde se levantaron las zonas productivas y los distritos artesanales, integrados o no en su urbanismo. El objetivo principal es analizar estas demarcaciones productivas en su relación con el resto de la ciudad y de las infraestructuras de comunicación, así como su desarrollo.

Published: February 2022

The paper presents the study results of photo and gamma radiation effect on the beryllium oxide (BeO) surface properties. Photoadsorption studies of О2 on BeO by the methods of infrared (IR) spectroscopy and manometry with a change in the temperature of preliminary annealing from 473 to 1073 K show that samples subjected to preliminary training at 473 K are most active. The maximum of adsorption activity on g-irradiated beryllium oxide is observed on the samples annealed at 673 K before the irradiation. The maximum of paramagnetic centers (PMCs) is also observed on samples annealed at this temperature. Comparison of electron paramagnetic resonance (EPR) and adsorption studies shows that absorption of H2 and O2 leads to the destruction of paramagnetic centers. It is assumed that, upon irradiation, adsorption centers with electron and hole modes are formed on the surface of BeO.

The article draws attention to the issues of ensuring safety and improving the effectiveness of projects in the context of innovative development. Modern state documents developed in the interests of ensuring environmental safety are presented. The main provisions of the Decree of the President of the Russian Federation dated 02.07.2021 No. 400 «On the National Security Strategy of the Russian Federation» aimed at ensuring environmental safety are considered. The author notes that the absence of a comprehensive environmental-oriented and risk-focused expertise of innovative projects in Russia is a serious threat to national security. The current state of affairs in the field of expertise of innovative projects is the basis for the occurrence of damage to the environment, the population and the economy, the magnitude of which is often several times greater than the magnitude of the commercial effects of innovative projects. The necessity of formation and development of the institute of integrated environmental-focused and risk-focused expertise of projects of complex systems and innovative technologies based on modern ideas about the ecological imperative of technological development of the civilization of the XXI century — the civilization of risk and knowledge.

Evaluation of the effectiveness of anti-crisis management of municipal unitary enterprises of the housing and communal sector in the territory of the Sverdlovsk region
Authors: Chechulin Ivan , Kudryavtsev Aleksandr
Published: February 2022

The article is devoted to the enterprises management’s effectiveness in the housing and communal sector, faced with economic difficulties, and search for possible ways to increase their financial stability. The relevance of the article is anticipated to the high social significance of the tasks facing the enterprises of the housing and communal sector, due to the need to resist global warming. According to the author, methodological approaches to anti-crisis management do not meet modern challenges and requires scientific revision. In order to verify this assumption, as well as to identify a possible direction for the further development of management approaches, methods of ranking statistical indicators and empirical-analytical methods were applied. As a result of the study, the author identified the most useful macroeconomic areas of company insolvency management, identified the most applicable models for predicting the likelihood of company insolvency, established low efficiency of enterprise rehabilitation procedures, and determined that public-private partnerships have the best economic indicators. The theoretical significance of this study lies in the determination by the author of the insufficient accuracy of the most common models for predicting bankruptcy, determination the most accurate and applicable to the industry, which can be used as a baseline for the preparation of the author’s own model. The practical significance is due to the fact that the author revealed better economic indicators of the public-private enterprises, which, in the author’s opinion, indicates the need for further development of the of anti-crisis management‘s methodology in the housing and communal sector with the aim to implement public-private partnerships.

Authors: Odabasi E. , Dayioglu A. Y. , Demir Yetis A. , Aydilek A. H.
Published: February 2022

Use of recycled materials instead of earthen materials is one way to improve the sustainability of highway infrastructure. Since geotextile filters and separators are used in such construction schemes, hydraulic compatibility of geotextile filters with recycled materials and their long-term performance is essential. A series of long-term filtration (LTF) tests were performed to evaluate the hydraulic compatibility of several woven and nonwoven geotextiles with four recycled materials commonly used in construction (recycled concrete aggregate, recycled asphalt pavement, foundry sand, and recycled asphalt shingle). Upon completion of the LTF tests, grain size analyses, permittivity tests, image analyses, and piping measurements were conducted to investigate the clogging and retention behavior of the geotextiles. The results indicated that majority of the recycled materials tested were compatible with the nonwoven and woven geotextiles. Excessive piping was not observed even under relatively high hydraulic gradients. Permittivity and percent open area were the main parameters that influenced the retention performance of the nonwoven and woven geotextiles, respectively. The success of the existing criteria in predicting the filtration performance was inconsistent, suggesting that a detailed parametric study was needed to propose new filter criteria for these materials.

COVID-19 infection rate in the construction and cleaning industry: known infections and unrecorded cases. Part 1 – men Aim: The aims of this study were to assess the prevalence of COVID-19 in the construction industry in Germany, the number of unreported cases (under-recording factor) and whether an increase in risk compared to the general population can be assumed in the construction industry, and to examine the influence of certain possible job-specific risk factors such as the location and nature of the activity on the infection-rate. Methods: We conducted a COVID-19 seroepidemiological study of n = 3,493 men who attended one of the participating occupational health service centres for occupational medical examinations. A questionnaire was also completed by the study participants on living conditions, occupational activity, position in the occupation and known previous infections, among other factors. Results: 3.4% of the men disclosed a previous COVID-19 Infection. Of the n = 3,374 men with no known infection, COVID-19 antibodies were found in n = 84 of the subject group (2.4 % relative to the basic population), hence 5.8 % of the men had a COVID-19 infection. Relative to the known COVID-19 infections, the number of unreported cases of non-diagnosed COVID-19 Infections (under-reporting factor) was thus 70 %. A clear influence of work on construction sites and in the cleaning industry could not be detected. For office work, there were indications of an increased risk of infection. Compared to the general population, it is unlikely that there is an increased risk associated with working on construction sites. The infection rate was lower in smokers than in non-smokers. Conclusion: Given 70 % unreported cases, company doctors, for instance, should use the determination of COVID-19 antibodies in unvaccinated men without a known infection to offer a booster vaccination to them as well as to persons with a known infection. Furthermore, the under-reporting factor, which is not low, indicates that not all people with an infection are successfully recorded, so that compliance with general protective measures is of great importance for containing the pandemic. Keywords: COVID-19 – infection rate – unrecorded cases – construction industry
A critical review of initial Resource and Reserve tonnage estimation and reporting
Authors: Roux L.
Published: February 2022

This review was initially motivated by the author's own experience in attempting to reconcile run-of-mine production tons with the Coal Resource and Reserve estimation of mineable, in-situ tonnages. The primary scientific measurements and observations that are collected during exploration at the beginning of the value chain will have a profound effect on the future of the mining operation. Due diligence must be exercised during the planning of a new mine and during the life of an existing mine. The comments provided by the technical and economic assessment group of Venmyn Deloitte confirmed the need for this critical review. They found the reporting of Coal Resources in South Africa to be inconsistent. This was particularly problematic in the Waterberg Coalfield in Limpopo Province. In this coalfield there are two types of coal deposit present. The first is comprised of the thick intercalated, cyclic coal and shale/mudstone sequences of the Volksrust Formation. This overlies multiple coal seams within the Vryheid Formation, each of which is thick enough to be extracted as an individual raw coal unit. On the other hand, the interbedded coal and shale seams of the Volksrust Formation require beneficiation to separate the coal from the shale. The review examines practices and methods, investigates alternatives, provides checks and balances, and tests these against actual production reconciliations. In conclusion, the best estimates of the mineable, in-situ tonnage will be obtained from the air-dry raw material density. These estimates should be adjusted afterwards to allow for free moisture content. The adjustments are derived from reconciliation data. The greatest contributing factor to the over-estimation of Reserve tonnages is the moisture content of the raw material. This fluctuates significantly under varying conditions in situ, as well as upon exposure to the natural environment. The air-dried density of the raw material includes inherent (structurally bound) moisture within the matrix. It provides credible tonnage estimations of raw material available while also providing an indication of voids within the volume of material being assessed. The calculated solids percentage can be used to adjust the specific gravity, which is determined via the Archimedes principle. This will supply a representative estimate of the material to be mined.
Proposta d’un model d’avaluació de les competències socials dels alumnes d’educació primària des de l'àrea d'Educació Física

Aquest article proposa un model d’avaluació de les competències socials des de l’àrea d’Educació Física. Per a la seva elaboració s’utilitza un disseny observacional nomotètic (diversos participants que executen una mateixa tasca), de seguiment (diferents patrons de conductes observades durant mesos) i multidimensional (diverses dimensions que es corresponen amb els criteris de l’instrument d’observació), amb la creació d’una eina ad hoc validada per experts. D’aquest disseny se’n deriven una sèrie de decisions sobre els participants, els instruments d’observació, de registre i el procediment d’anàlisi. S’utilitza l’anàlisi seqüencial de retards, prospectius i retrospectius, per obtenir les taules seqüencials que generen les discussions i l’anàlisi de resultats. L’anàlisi seqüencial posa en relació conductes obtingudes diacrònicament i busca patrons de repetició en el temps. D’altra banda, l’anàlisi seqüencial de retards es complementa amb la utilització de la tècnica de coordenades polars que permet obtenir un mapa complet de les interrelacions entre les diferents categories de les diverses dimensions. La característica més destacada de la recerca és la utilització del programa HOISAN 1.6.3 (Hernández-Mendo et alii, 2012), que permet, per primer cop, calcular de manera informatitzada l’anàlisi de coordenades polars. A partir de l’eina ad hoc i dels resultats obtinguts s’elabora la proposta de model d’avaluació de les competències socials de l’àrea d’Educació Física.
Indicadors d’avaluació per recollir informació a les sessions de psicomotricitat del segon cicle d’educació infantil
Authors: Segura Meix Míriam
Published: February 2022

Són moltes les escoles que actualment aposten per una psicomotricitat vivencial. Els estudis existents i la difusió que se n’ha fet han permès que els mestres i els psicomotricistes apliquin programes educatius basats en aquest corrent. L’acte de dissenyar, escollir els materials, preparar la sala, etc. ja és un hàbit per a molts educadors. No obstant això, l’avaluació i la coherència amb el currículum actual no està prou consolidada en totes les escoles. En aquest article el que pretenem és facilitar la tasca docent i oferir recursos per poder dissenyar instruments de recollida de dades, partint del treball d’investigació previ d’un grup de mestres de diferents nivells educatius. Basant-nos en l’anàlisi del currículum del segon cicle d’educació infantil, es presenta una distribució temporal d’indicadors relacionats amb la disciplina de psicomotricitat que engloben aspectes motors, relacionals, afectius i conductuals.

Technique of Hydrothermal Power System Balance Calculation with Allowance for the Regime Features of a Hydropower Station Based on the Cost of a Hydraulic Resource
Authors:   Novosibirsk State Technical University, Sekretarev Yuri I. , Myatezh Tatiana V. ,   Novosibirsk State Technical University
Published: February 2022

The present paper proposes a universal method for analyzing the efficiency of technical systems using the combination of an optimization method and a method of marginal utility evaluation. At present, the problem of optimal load distribution in the power system between a hydropower plant (HPP) and thermal power plants (TPP) is solved using the equality of the differential incremental rate characteristics of fuel consumption at TPP and water consumption at HPP by the Lagrangian multiplier method. In this case, the number of iterations can be five or more. The proposed approach is based, first of all, on the correct representation of the differential characteristics and calculation of a hydro resource price for the operational control of the HPP. Based on the comparison of water volume at a HPP and fuel amount at combined heat and power plants (CHPP) used for generation of 1 kW power, it is possible to determine a water price for a HPP. Using the examples of Novosibirsk HPP and CHPP, it is expected to develop an estimation of economic effect from the implementation of the developed criteria, the proposed method of determination of a water price at HPP. As a result of implementing the developed method for the HPP, a price of sold electricity in the flexible energy market will be comparable with the price for sold electricity produced at CHPPs, being equal to approximately 12 rubles/kW∙h
Autocompensation of Reactive Power in Electric Networks
Authors:   Vladimir Electromechanical Plant, Pavlov Valentine D.
Published: February 2022

The aim of this work is to assess the influence of a cascade of transformers and shunt reactors on the reactive power in the network at a symmetrical load. It has been established that any phase is a source of reactive power for the other two phases. Conversely, any two phases are the source of the third phase reactive power. Thus, with a symmetrical load, self--compensation of reactive power occurs. A cascade of transformers is represented by their simplified equivalent circuits (excluding scattering). If the transformers are identical, then the reactive power flow from the load is divided between them into equal parts. Therefore, the reactive power flow in the outer section is three times less than in the inner section. In accordance with this, in a real network, with an increase in the number of transformer substations and shunt reactors, the reactive power flow significantly decreases with distance from the load
