BACKGROUND

Wearables provide opportunities for frequent health data collection and symptom monitoring. The feasibility of using consumer cellular smartwatches to provide information both on symptoms and contemporary sensor data has not yet been investigated.

OBJECTIVE

This study aimed to investigate the feasibility and acceptability of using cellular smartwatches to capture multiple patient-reported outcomes per day alongside continuous physical activity data over a 3-month period in people living with knee osteoarthritis (OA).

METHODS

For the KOALAP (Knee OsteoArthritis: Linking Activity and Pain) study, a novel cellular smartwatch app for health data collection was developed. Participants (age ≥50 years; self-diagnosed knee OA) received a smartwatch (Huawei Watch 2) with the KOALAP app. When worn, the watch collected sensor data and prompted participants to self-report outcomes multiple times per day. Participants were invited for a baseline and follow-up interview to discuss their motivations and experiences. Engagement with the watch was measured using daily watch wear time and the percentage completion of watch questions. Interview transcripts were analyzed using grounded thematic analysis.

RESULTS

A total of 26 people participated in the study. Good use and engagement were observed over 3 months: most participants wore the watch on 75% (68/90) of days or more, for a median of 11 hours. The number of active participants declined over the study duration, especially in the final week. Among participants who remained active, neither watch time nor question completion percentage declined over time. Participants were mainly motivated to learn about their symptoms and enjoyed the self-tracking aspects of the watch. Barriers to full engagement were battery life limitations, technical problems, and unfulfilled expectations of the watch. Participants reported that they would have liked to report symptoms more than 4 or 5 times per day.

CONCLUSIONS

This study shows that capture of patient-reported outcomes multiple times per day with linked sensor data from a smartwatch is feasible over at least a 3-month period.

The possibilities of Open Science for knowledge transfer in the science-policy interface
Authors: Olesk Arko , Kaal Esta , Toom Kristel
Published: June 2019

This paper explores the possible role of Open Science in the knowledge transfer between research and policy, focusing on its potential use by scientific councillors at Estonian ministries. Qualitative interviews with scientific councillors show that they perceive their role as intermediaries between research and policy and focus their work on improving the quality of research commissioned by their ministry. This process, for them, involves using existing academic articles and datasets to which, however, they lack official access. We show that Open Science can contribute to knowledge transfer if there are knowledge brokers in public sector organizations.
Between offensive and defensive mediatization. An exploration of mediatization strategies of German science-policy stakeholders
Authors: Scheu Andreas
Published: June 2019

The study contributes to mediatization research. Mediatization is understood as a process during which individual and collective actors adapt towards the demands of publicity and public attention. The manuscript introduces a differentiation of mediatization strategies, ranging from defensive to offensive strategies. This conceptual differentiation is applied empirically regarding relevant stakeholders within the German science-policy constellation from politics, science, and science funding. Results are based on 35 in-depth interviews with decision makers. The results section deals with similarities and differences considering the mediatization of organizations, and introduces a typology of science-policy stakeholders based on the conceptual differentiation of mediatization strategies.
The Effect of Spatial Distance and Domain Knowledge Distinctiveness on Auditor Reliance on IT Specialists
Authors: Hirsch Rina M.
Published: June 2019

Due to limitations in IT expertise, auditors frequently rely upon IT specialists during audit engagements. Does social similarity between the auditor and an IT specialist induce social biases that affect the auditor's reliance on the specialist? Using an experiment with 60 auditors, I examine how financial auditors' reliance on IT specialists is affected by two dimensions of social similarity: the IT specialist's spatial distance (in-house office location versus sourcing from another office) and domain knowledge distinctiveness (distinct versus overlapping) relative to financial auditors. My findings provide evidence of a possible boundary condition to the widely accepted social identity theory by documenting the interaction of two dimensions of social similarity on auditor behavior. Specifically, when IT specialists possess distinct (overlapping) domain knowledge, auditors place greater (similar) reliance on out-of-office specialists relative to in-house specialists.

The aim of this study was to understand the effects of Blighia sapida aril consumption on viscera and their functionalities. For this instance, quantities of arils were cooked (500 g/l) and lyophilize. Six homogeneous groups of young rats were fed ad libitum with six different diets which can be distinguished by the level of Blighia sapida aril powder put in the diet formulate. There were control diet (0% Blighia sapida arils powder), Bs1 (6.25% Blighia sapida arils powder), Bs2 (12.5% Blighia sapida arils powder), Bs3 (25% Blighia sapida arils powder), Bs4 (50% Blighia sapida arils powder) and Bs5 (75% Blighia sapida arils powder). At the end of the experimentation, blood samples were collected and were used for analyses of plasmatic bilirubin content. After sacrificed the experimental rats, stomach, liver, kidney, heart and lung were removed and weighted. These organs were processed for histopathological studies. There were no different variation (p>0.05) of bilirubin content between rats which received control diet and those which received the experimental diets. Organs weight of rats fed with diets Bs1, Bs2 and diet Bs3 were not globally different (p>0.05) compare to those of the control diet while organs weight of rats fed with diets Bs4 and Bs5 were globally reduced (p<0.05). No pathologies on viscera were observed when Blighia sapida aril powder is consumed with moderation (under a value of 50 % of nutrition value need). But, when consumed with exaggeration it provokes lipid nephrosis lesions on kidneys cells and necrosis on hepatic parenchyma. We can notice that Blighia sapida aril is rich nutritiously but it must be consumed with moderation in order to avoid pathologies on viscera.

Adolescence is a period of transition from childhood to adulthood with developmental tasks to obtain social roles and emotional freedom from parents, but adolescents are still not able to control themselves properly. This study analyzes the influence of parents socialization method and self control on manners character of adolescence. This study used a cross-sectional research design. A diverse sample of both junior high school students in Cibinong sub-didtrict, Bogor District (n=187; 87 boys and 100 girls) were selected considering proportionate random sampling method to answer survey using questionnaires. The collected data was analyzed by descriptive statistic and path analysis. Findings of this study suggest that there is no difference between boys and girls in parental socialization method, self control, and manners character of adolescence. The results showed that parental socialization method (ρ=0,333) and self control (ρ=0,365) had direct positive effects on manners character of adolescence. Furthermore, parents socialization method also had indirect effect on manners character of adolescence through self control variable (ρ = 0,108). Total effect of the parental socialization method on the character manners is 44,1 percent, greater than effect of self control on the manners character ofadolescence (36,5%).
Un motivo literario a la luz de La Celestina: de los libros de caballerías al teatro áureo
Authors: Martín Romero José Julio
Published: June 2019

El presente estudio determina la existencia de un motivo literario no detectado hasta ahora: el contratiempo peligroso de la cita secreta nocturna de los amantes. Demuestra que su origen se encuentra en la muerte de Calisto en La Celestina. Además, establece la estructura del motivo: la cita erótica secreta y nocturna, la aparición de personajes inoportunos y la lucha consecuente. Asimismo, analiza su aparición en diversos libros de caballerías, así como en el teatro áureo (El caballero de Olmedo de Lope de Vega). Este artículo, por tanto, muestra que la influencia de los libros de caballerías va más allá de lo que normalmente se acepta y alcanza diversos géneros literarios.

Published: June 2019

Tomato is a significant vegetable crop with numerous health benefits derived from its carotenoids, flavonoids and other phytonutrients contents. This work studies the nutritional qualities and carotenoids contents of five different cultivars of tomatoes (San Marz, Nasmata, Roma VF, Ogbomoso local and 4-lobes). The variations of pH, titratable acidity, reducing sugar, total solid, lycopene and beta-carotene contents of these tomatoes were investigated under ambient temperature and field ripening techniques and the mean values of these parameters investigated at different ripening stages and techniques were compared. Lycopene contents were significantly higher (p < 0.05) in tomatoes subjected to field ripening compared with those ripened under ambient temperature. The highest lycopene content (17.18 μg/g) was observed in Roma VF cultivar at fully-ripe stage under field ripening technique while the lowest value (0.64 μg/g) was in 4-lobes cultivar at semi-ripe stage under ambient temperature ripening. Similar trend was observed in the variation of betacarotene (a pro-Vitamin A index) among the tomato cultivars. The evaluated reducing sugar contents (ranging from 1.84 to 5.23 μg/g) were significantly higher (p < 0.05) in fully-ripe tomatoes compared to semi-ripe ones under field ripening and the trend was reversed for some cultivars under ambient temperature ripening. The titratable acidities of the tomatoes were significantly higher at the semi-ripe stage (0.24 to 0.38 %) under field ripening than those obtained under ambient temperature ripening (0.15 to 0.25 %). The pH of the tomatoes ranged from 3.58 to 4.07 and 3.46 to 5.40 under field and ambient temperature ripening, respectively, and the higher pH values obtained under ambient temperature ripening condition could make such tomatoes unsuitable in tomato processing plants. Consumption of tomatoes for the purpose of dietary antioxidant lycopene and pro-Vitamin A could maximally be achieved at fully-ripe stage under field ripening condition.
An Assessment of Anaerobic Thermophilic Co-Digestion of Dairy Cattle Manure and Separated Tomato Greenhouse Waste in Lab-Scale Reactors
Authors: Kovačić Đurđica , Kralik Davor , Jovičić Daria , Spajić Robert
Published: June 2019

Anaerobic co-digestion of dairy cow manure (DCM) and separated tomato greenhouse waste (tomato stalks and leaves (TSL) and rotten and damaged tomato fruits – TF) was conducted under batch thermophilic conditions (T = 55 °C) for period of 45 days. Concentrations of substrates (tomato waste) were 5 and 10% (w/v). Each substrate, as well as experimental mixtures, was analysed in order to specify the content of pH, total solids (TS), volatile solids (VS), total extractable nitrogen (TN) and total organic carbon (TOC). Biogas yield and composition, as well as cumulative biogas curves, were reported. In comparison to DCM monodigestion (329.5 cm3·g−1 VS), biogas yield was significantly improved in experiment C (365.1 cm3·g−1 VS) (with 5% (w/v) TF added), whereas methane yield did not show any significant difference. Experiment D (with 10% (w/v) TSL added) resulted in significantly lower biogas and methane yields in contrast to the rest of experiments performed. Average methane content in all analysed experimental samples ranged from 65 to 69%. It is evident from the results that biogas production can be improved by addition of separated tomato greenhouse waste to DCM process and issue of organic waste disposal could be effectively solved.

Proposed paper deals with experimental tests performed on the Nieman M01 FZG test rig. Experiments were carried out in accordance with STN 65 6280 standard for FZG scuffing tests, from which load values for each load level were obtained. HCR gears made of 16MnCr5 material were utilized during experimental tests. Gear surface was deposited by PVD coatings of nACRo4 and TiAlN + DLC. Conventional lubricant MADIT PP 90H and biological lubricant OMW Biogear S150 were selected for lubrication environments. Aim of the experimental tests lied in application and comparison of PVD coatings deposited on HCR gears. Values of the maximum height of the assessed profile Rz for tip and reference diameters were measured after each load level. Results of experimental tests were statistically processed and relations between the maximum height of assessed profile Rz and load levels for both utilized coatings in both environments were established on the basis of these results.
Comparison of Mainstream Smoke Composition from CR20 Resin Filter and Empty-Cavity Filter Cigarettes by Headspace SPME Coupled with GC×GC TOFMS and Chemometric Analysis

Published: June 2019

A previously established method based on headspace solidphase microextraction (HS-SPME) and comprehensive two-dimensional gas chromatography (GC×GC) coupled to time-of-flight mass spectrometry (TOFMS) has been used to evaluate and compare the profiles of semi-volatile compounds present in mainstream tobacco smoke particulate matter trapped on glass fibre filters for two types of cigarettes differing only in filter design. In the first cigarette, the filter cavity contained approximately 60 mg of a weakly basic macroporous polystyrene resin cross-linked with divinyl benzene and with surface amine functionality (CR20), whereas in the second cigarette, it was empty.

Relative quantitative analysis, chemical identification, and chemical grouping allowed the use of both parametric and non-parametric analyses to identify differences in the chemical composition of the smokes from these cigarettes. The analysis demonstrated that in addition to the selective partial removal of volatile carbonyls and HCN demonstrated previously, CR20 selectively, but incompletely removed 316 compounds from the particulate phase of cigarette smoke, mainly aryl and aromatic hydrocarbons as well as other more volatile species. In contrast, the relative proportion of amines, hydroxylated aromatic compounds and less volatile species was increased in the smoke from the cigarette containing CR20 in the filter.

Our findings show that high resolution GC techniques combined with mass spectrometry and chemometric approaches are powerful tools for deconvoluting the complexity of combustion aerosols, as well as helping to identify changes in chemical composition resulting from modifications to cigarette designs.

Education for Sustainability: Developing Ecocritical Literature Circles in the Student Teacher Classroom
Authors: Guanio-Uluru Lykke
Published: June 2019

How can student-teachers learn efficient ways to encourage sustainability thinking in their pupils and fulfil the competence aims on sustainability outlined in national subject curriculums as a response to UNESCO’s programme on Education for Sustainable Development, ESD? The core hypothesis of this project was that tailored literature circles, focused on the ecocritical aspects of literary texts, would make student-teachers aware of how they can use literature as a process to reflect on sustainability. This would enable them to incorporate sustainability thinking into their own teaching practices.

The project’s tailoring of the standard literature circle roles (Daniels 1994, 2002, 2006) involved the design of reading roles that highlighted ecocritical and generic aspects of the studied texts and the application of an analytical matrix developed by literary scholars researching the representation of nature in children’s and young adult literature. This article presents the results of a small-scale study testing the ecocritical literature circles approach and its impact on student-teachers’ conception of their own ability to meet the competence aims on sustainability in their teaching. The intervention included lectures on ecocriticism and on the posthuman debate prior to the literature circles and student feedback through pre- and post-circle questionnaires. It was implemented in the teacher-training classroom, working with dystopian science fiction texts for young adults. These texts present the reader with visions of the future. The study showed that the ecocritical literature circles, and in particular the ecocritical reading roles, were considered useful by the participating student-teachers. The participants also reported a significant increase in confidence relative to their own ability to discuss sustainability issues with their pupils.
The Need for a Sustainable and Balanced Critical Approach in Book Reviews
Authors: Demir Cuneyt
Published: June 2019

Book reviews are important in offering guidance to prospective readers. What is expected from them is to be not only informative and evaluative but also unbiased and balanced. Therefore, the use of correct discourse is necessary to prevent asymmetrical domination of the reviewer, and to create a healthy setting to sustain credibility of book reviews in terms of prospective readers. In that sense, this study investigated two discourse devices, namely euphemism and dysphemism. Euphemism can be defined as polite and agreeable words or expressions that are used in place of harsh or offensive ones; however this research investigated if these expressions might lead to undue praise for a book. On the other hand dysphemism is a kind of language that uses disparaging and derogatory terms instead of complimentary or neutral ones. Reviewers may consciously or unconsciously use these linguistic devices in their critiques of books, however; the balance between them is of great importance because any unbalanced negative or positive critical act may bring about unfair judgements in would-be readers regarding the quality of the mentioned book. The present study investigated a hundred book reviews and picked up euphemistic and dysphemistic expressions. The result is of importance in helping the book reviewers to choose the true word of expression without being unnecessarily soft or offensive. Any possible biases against a book because of book reviewers’ inattentive word selection may be prevented in view of the present study. Finally, this study is important for instructors of academic writing to increase their awareness for the importance of discourse devices in book reviews, which is necessary for sustainable development of education; in other words, instructors of academic writing at universities may rearrange their instruction curriculums through saving a slot for euphemism and dysphemism for prospective students.

Published: June 2019

E-leadership has not been thoroughly explored, especially in Thai higher educational institutions. This study was conducted in a scenario planning workshop with 20 participants who were administrators, lecturers, staff members, and stakeholders of both Thai public and private higher educational institutions. The aim of this research was to develop the scenarios for Thai higher educational institution leaders to use E-leadership in 2027. The three scenarios for educational leaders to use E-leadership were developed for future Thai higher educational institutions and were e-leaders and international collaborations; e-leaders, innovation and sustainable environment; and e-leaders and the current situation. The scenarios were developed using STEEP analysis. The social aspect includes the phenomenon of youth called “digital natives”, increased individual learning and society of learning, generation gap, well-educated employees, and an aging society. The technological aspect is acclimatizing to the need of users, advancing technology and innovation, technology being everywhere, and competition within technology development. The economic aspect considers increase in oil prices, investment in university, increasing numbers of cross-institutions, and rapid economic growth in ASEAN. The environmental aspect considers global warming, climate change, and redesigns learning space. Lastly, the political aspect considers government policies in education and improved environmental governance. It does not only benefit higher education, but also schools or any organization that could apply this sustainable education research to develop human resources for the future.
“Verbindlichkeit”: Some drafts of a groundwork in moral philosophy
Authors: Moskopp Werner
Published: June 2019

All of metaethical positions today can be replaced by a universal architecture of moral philosophy, all but one: moral realism. Here, I use the term “metaethics” to refer to any theory of ethics concerning the groundwork of ethics, on the one hand, and the inquiry of the use of philosophical words, concepts or methods on the other. In this article, I will present my hypothesis that in moral philosophy, we do not need any specialized metaethics at all. Metaethics as a discipline of philosophy is only required by the work of moral realists, who try to show us a realm of values and norms that exist (per se) naturally, non-naturally or supernaturally. How can they know? The effort of metaethical realists cannot be proven either in ontology or in the philosophy of language or in cognitive science or in any meta-science that works en plus to ethics, because even in every additional discipline, we have to accept the presupposition of a validity of judgments. So, let us try it the other way around; we have to find a way to found ethics by following its structures, and that means, based on David Velleman’s concepts: a) We have to search for a ubiquitous point of ethical theory in its foundation – here, no kind of value or norm can be found that is not based on a universal formal structure of normativity. b) We have to start an empirical inquiry to collect norms and values in actual use. MFT, moral psychology and moral sociology are in charge here. The combination of such an abstract groundwork with mere empirical study has to be legitimized again. Hence, I am going to try to sum up the main ideas of such a project to show the relevance of a new architecture of moral philosophy today. There is a line of reasoning that addresses the possibility of a transcendental critique in practical philosophy; therefore, it has to look into the different notions of “intuition” in moral methods like it was used by Sidgwick (Rashdall, Green, Ross, Brentano, McTaggart) and Moore on the one hand and Brentano and Bergson on the other. In my view, there is a way to combine these perspectives using the two-level-model of Hare, Singer, Greene, where “intuition” is used to categorize habits and customs of the common sense morality in general while a critical reflection uses act-utilitarian calculus to provide a universal decision – in the sense of “concrete reason” – for any possible actor in a singular situation (Hegel, Peirce, Bloch etc.). The change between these levels may be explained by means of a pragmatistic kind of continuum of research with an ideal summum bonum in the long run and a concept of common sense morality as can be found in every group or society.
Modernism and nihilism of the Constitution for the Earth
Authors: Lesňák Slavomír
Published: June 2019

This article uses the post-modern Nietzsche affirmation as a criterion for an analysis of the philosophical concept of the Constitution for the Earth (Šmajs, 2015) and other texts by Josef Šmajs, the principal author of the theory of evolutionary ontology. The author draws the attention of the group of authors of the Constitution for the Earth to the risk of the modernist and nihilist application of evolutionary ontology and proposes that the theory be extended to include new criteria and methods to enable it to be applied in a more acceptable manner. The author places efforts aimed at the biophilic transformation of culture into the value-based and ethical framework of moderate anthropocentrism instead of the ecocentric approach preferred by the creators of evolutionary ontology. The author also underlines the risk of the application of an ecocentric approach through the application of recent analysis of media presentations of those who support and deny climate change in the work entitled Environmental Ethics and Behavioural Change (Franks, Hanscomb & Johnston, 2018).
Effective altruism for the poor
Authors: Synowiec Jakub
Published: June 2019

The aim of the paper is to contribute to the debate on effective altruism. It is an attempt to present it as a universal moral proposition – not only a new charity model for the richest citizens of the world. The article starts with a definition of a hypothetical group of relatively-poor effective altruists. Their hypothetical living conditions and opportunities are juxtaposed with the theory of effective altruism developed by Peter Singer and William MacAskill and with career guides proposed by 80000hours.org – one of the websites gathering effective altruists. In the last part, selected practices for relatively poor effective altruists are described. The conclusion of the paper is, that although most of the reflections behind the concept of effective altruism are developed for the richest people in the world, it is a universal ethical position that can be applied into lives of relatively poor people, whose contribution should not be underestimated.

Authors: Varecha Daniel , Kohar Robert , Brumercik Frantisek
Published: June 2019

The article is focused on braking simulation of automated guided vehicle (AGV). The brake system is used with a disc brake and with hydraulic control. In the first step, the formula necessary for braking force at the start of braking is derived. The stopping distance is 1.5 meters. Subsequently, a mathematical model of braking is created into which the formula of the necessary braking force is applied. The mathematical model represents a motion equation that is solved in the software Matlab by an approximation method. Next a simulation is created using Matlab software and the data of simulation are displayed in the graph. The transport speed of the vehicle is 1 〖m.s〗^(-1) and the weight of the vehicle is 6000 kg including load. The aim of this article is to determine the braking time of the device depending from the input data entered, which represent the initial conditions of the braking process.

Authors: Sarker Dulal , Khan Abdur Rouf , Islam Muhaiminul
Published: June 2019

Land use-transportation comprehensive planning has become an increasingly common technique in regional and sub-regional planning processes. Since land use management strategies act as an effective tool to achieve transportation planning objectives, it is important to identify the relationship between land use pattern and travel behaviour. This study examined the relationship between transportation and land use in Rajshahi city. Rajshahi is a major urban, commercial and educational centre of Bangladesh. In Rajshahi, Shaheb bazaar zero points to New Market road is one of the most important roads. After construction of this road in 2013 intense development has taken place beside it. To identify this primary relationship data has been collected from different types of field survey. Then the impact of land use and transportation has been determined by comparing with the previous database. The findings of the study show that there exist a reciprocal relationship between land use and transportation system and the impacts on both. The study also notes that the impact of transportation on land use is more than the impact of land use on transportation. The study will help to control the haphazard growth and traffic congestion of the concerned area in the future.

The aim of this article is to define the theoretical basis of brand value from the viewpoint of domestic (Slovak) and foreign authors and its impact on sales. This includes a regression and correlation analyses focused on investigate the dependence between the brand value and sales in automotive industry. The basic sources of research were secondary data obtained from worldwide surveys in the form of rankings published by Forbes magazine, annual reports of companies and published professional publications. General scientific methods were applied for the processing of the data, as well as mathematical-statistical methods to evaluate the data collated from the results of regression and correlation analyses and test the linear independence. The results of analyses show that the brand value and sales are linearly dependent, specifically it is medium-strong direct linear dependence. Therefore, the brand value has a direct effect on sales volume.
Dynamic magnetoelastic properties of TbxHo0.9−xNd0.1(Fe0.8Co0.2)1.93/epoxy composites

Published: June 2019

TbxHo0.9−xNd0.1(Fe0.8Co0.2)1.93/epoxy (0 ⩽ x ⩽ 0.40) composites are fabricated in the presence of a magnetic field. The structural and dynamic magnetoelastic properties are investigated as a function of both magnetic bias field Hbias and frequency f at room temperature. The composites are formed as textured orientation structure of 1–3 type with 〈1 0 0〉 preferred orientation for x ⩽ 0.10 and 〈1 1 1〉-orientation for x ⩾ 0.25. The composites generally possess insignificant eddy-current losses for frequency up to 50 kHz, and their dynamic magnetoelastic properties depend greatly on Hbias. The elastic modulus (E3
H and E3
B) shows a maximum negative ΔE effect, along with a maximum d33, at a relatively low Hbias ~ 80 kA/m, contributed by the maximum motion of non-180° domain-wall. The 1–3 type composite for x ⩾ 0.25 shows an enhanced magnetoelastic effect in comparison with 0 to 3 type one, which can be principally ascribed to its easy magnetization direction (EMD) towards 〈1 1 1〉 axis and the formation of 〈1 1 1〉-texture-oriented structure in the composite. These attractive dynamic magnetoelastic properties, e.g., the low magnetic anisotropy and d33
,
max as high as 2.0 nm/A at a low Hbias ~ 80 kA/m, along with the light rare-earth Nd element existing in insulating polymer matrix, would make it a promising magnetostrictive material system.
Simultaneous quadriceps and contralateral patellar tendon ruptures in a patient with chronic renal failure following electric shock; a case report and review of the literature

Published: June 2019

Bilateral extensor tendon ruptures of the knee are not uncommon. However, simultaneous ruptures of the patellar tendon (PT) and contralateral quadriceps tendon (QT) are relatively rare injuries. These ruptures are frequently associated with chronic renal failure and minor trauma. However, they can occur spontaneously in healthy individuals. In this case report, a 43-year-old male with chronic renal failure who sustained bilateral extensor tendon ruptures (right knee: QT rupture, left knee: PT rupture) following an alternating current electrical shock was reported. To our knowledge, simultaneous quadriceps and contralateral patellar tendon rupture following an electric shock have not been reported yet. Etiology, mechanism of injury and treatment options of this rare injury are discussed together with a thorough literature review.

Published: June 2019

Introduction. Bisphosphonates (BPs) represent the main therapy in patients with osteoporosis, although a long-term treatment can lead to atypical fractures.

Material and methods. We conducted a retrospective study between 2008 and 2017 and included 23 female patients with atypical femoral fractures (AFFs). The mean period of BPs therapy administration was 5.2 years. We included 7 subtrochanteric fractures and 18 femoral shaft fractures. Two of the total patients presented bilateral femoral fractures. 18 patients presented prodromal symptoms from 2 to 18 months before the diagnosis of fractures, all of them following low energy trauma. All the patients included in our study underwent surgery with intramedullary nail or gamma nail. The postoperative mean follow-up was 2 years. Results. Of all 23 female patients with a total of 25 fractures – 10 underwent osteosynthesis with gamma nail and 15 underwent osteosynthesis with intramedullary nail. From the total number of patients: 13 patients achieved complete union, 6 presented delayed union and 3 non-union (2 intramedullary nail and one gamma nail), whereas in one patient treated previously with gamma nail we observed implant failure.

Conclusion. The treatment of AFFs after BPs therapy administration represents a challenge for orthopaedic surgeons regarding both surgical technique and postoperative follow-up.

Authors: Depken Craig , Chiseni Chanda , Ita Ernest
Published: June 2019

We utilize two waves of the National Income Dynamics Study in South Africa to estimate the returns to education in 2010 and 2012. We find that during this time period the returns to education were approximately 18% per year of education and that the returns were higher for females relative to males and higher for those living in urban relative to rural areas. The policy implications include a suggestion to continue investment in educational infrastructure, especially in rural areas, so as to increase the returns to education in those areas.
Characteristics of Undeclared Work in Service Sector in Countries of South East Europe
Authors: Bejaković Predrag , Stefanov Ruslan
Published: June 2019

The undeclared work is a complex and multifaceted phenomenon that has been present in all countries, regardless of its social and political establishment. Notwithstanding, the empirical evidence suggests that informal economy is more prevalent in countries with lower levels of GDP. Furthermore, the informal economy is present in sectors with lower level of capital and higher level of labour intensity. Therefore, the theory and everyday experience imply that the informal economy is more widespread among the services than the goods sectors. This paper provides an overview on the informal work and unofficial economy in the services sector in the former socialist countries in South East Europe. For the reduction of undeclared activities, it is necessary to simplify the procedures for establishing small businesses, to stabilize the tax system, to ensure high tax morale and trust in society and towards institutions, and to decrease the state regulatory burden.

Research subject. Anomalous sections present in the oil- and bituminous-bearing Bazhenov Formation (BF), in the central areas of the West Siberian basin, are considered to have emerged due to the injection of plastic pulp masses from the sedimentation slope into weakly lithified basal deposits. The aim of this research was to evaluate the as-emerged rocks by analyzing their composition and structure at the macro- and micro- levels. Materials and methods. We investigated reference well sections in the Imilor deposit to elucidate the interaction of the rocks with sandy-clay landslide pulp, their volumetric weight, ductility or brittleness, caused by the presence or absence of a continuous mineral frame. Results. According to core and well logging data, nine regional packs were distinguished in the BF stratotype. The maximal depth of the natural hydraulic fracturing of the rocks is explained by their high bulk density. The lateral movement of the main slump mass is found to have occured on the stratigraphic level of the first and second BF packs, since these layers possessed zero-buoyancy with regard to the injected pulp under their approximate equality in terms of bulk density. The traces of such active movements were revealed in rock samples from the walls of horizontal cracks in the form of clay intrusions having a thickness of about 0.1 mm and strict orientation of all micro-crystals along the walls and the flow. It is shown that inclusions of the rocks under investigation (bazhenits) in BF are generally characterized by their initial stratigraphic sequence, which is confirmed by the sequential disintegration of proto-bazhenit plates during the process of BF up-floating on a growing sedimentation slope. During the disintegration of the lithified and non-lithified layers of radiolarits, the former crumbled due to alternating loads, while the latter - mobile radiolarites - were represented by the hydraulic fracturing liquid, along with quicksand. Conclusion. A detailed petrographic study of core samples from intact deposits of the Bazhenov and George Formations and their anomalous sections have allowed their layer-by-layer comparison to be confirmed the landslide hypothesis and to be derived the information on the degree of lithification of the BF strata during the formation of its anomalous sections.
The variations of chemical composition and features of the distribution of rare elements in chondrites of fragments of the Chelyabinsk meteorite

Research subject. This paper reports the results of a series of experiments carried out to study the mineral and geoche mical features of 10 Chelyabinsk meteorite fragments. In addition, these fragments were analysed in terms of their chemical composition.

Materials and methods. The fragments under study were represented by light-grey granular rocks of the chondrite structure having either isometric or elongated shape. Their surface was largely covered with a black-brownish fusion crust with a thickness of approximately 1 mm. The petrogenic components of the meteorite and the content of rare elements were studied using the methods of chemical silicate analysis and ICP MS respectively. All measurements were carried out using an Agilent 7700x quadrupole mass spectrometer produced by the Agilent Technologies company. The composition of sulphides and metal particles was determined by electron probe microanalysis (PCMA) usinga JXA8200 microanalyzer (Jeol, Japan).

Results. The chondri and cementing matrix are found to be primarily composed of olivine and orthopyroxene. The inter-chondruli matrixis shown to consist of a pyroxene-olivine aggregate with inclusions of plagioclase, apatite, fused glass and ore minerals (tenite, kamasite, troilite, rarely pyrrhotine, pentlandite, single grains of chromite and ilmenite). The concentration of the majority of rare and ore elements in the Chelyabinsk meteorite samples is established to be close to their average values for LL-chondrite. When normalizing to coaly chondrite, the substance of the meteorite fragments and the average LL-chondrite were closest to coaly chondrite in terms of the content of siderophile elements (Mo, Ni, Cr, Co, V and Cu). At the same time, the studied meteorite fragments are shown to contain a significantly lower (nearly by one order) concentration of chalcophyle elements (Zn, Pb and Sn) with regard to С1.

Conclusion. A comparison of the obtained and published analytical data (ICP MS) has allowed us to make a conclusion on the geochemical heterogeneity of different meteorite remainst hat were scattered over a wide area of the Chelyabinsk Region. The acquired evidence suggests the differentiation of meteorite substance at early stages of the formation of terrestrial planets, which is likely to have occurred due to impact processes.
ANÁLISE E PROPOSTA DE MELHORIAS NA ARBORIZAÇÃO DE UMA AVENIDA DO MUNICÍPIO DE CAMPOS DOS GOYTACAZES, RJ

Published: June 2019

A arborização é um elemento relevante para minimizar os impactos causados pela urbanização desordenada. O objetivo da pesquisa foi analisar e propor melhorias para arborização viária no município de Campos dos Goytacazes, RJ. Com base na literatura especializada, as espécies de plantas foram identificadas e propôs-se, na via onde o estudo de caso foi conduzido, melhorias para a arborização local. Foram identificadas 245 plantas, pertencentes a 37 espécies, dentre as quais cerca de 40% são nativas do bioma Mata Atlântica. Mais de 20% das plantas são aroeiras, Schinus terebinthifolius, o que não é recomendado. Entre as plantas exóticas, algumas são inapropriadas para arborização urbana, como a Leucaena leucocephala e Nerium oleander. Constatou-se muitas inconsistências na arborização da área de estudo, como a presença de plantas em locais inapropriados, espécies exóticas, muitas delas consideradas invasoras, plantas tóxicas ou inapropriadas para arborização viária. Uma nova proposta de arborização foi elaborada para sanar os problemas diagnosticados, que também incluem baixa densidade arbórea, necessidade de planejamento e elaboração de regras que visem a implantação e manejo adequado da arborização municipal.

Authors: Leitão José Carlos , Fernandes Cleonice Terezinha
Published: June 2019

A revisão sistemática é um importante processo metodológico que faz a síntese dos estudos acerca de determinado tema, bem como mostra as lacunas para possíveis investigações. O presente estudo teve como objetivo revisar a literatura sobre estudos na área da inclusão de sujeitos com deficiência visual na rede regular de ensino brasileira. Foram utilizados descritores em língua portuguesa: “inclusão na educação”, “educação inclusiva”, “deficiência visual”, “deficientes da visão”, “educação dos cegos”, e encontradas 452 publicações em bases de dados eletrônicas, lista de referências e comunicação pessoal. Após avaliação, 11 estudos preencheram os critérios de inclusão. A revisão revelou: um reduzido número de artigos que discute metodologias de ensino e estudos experimentais; predominância de estudos de caso e descritivos, com ênfase na mostra dos serviços e percepção dos profissionais; inúmeras variáveis passíveis de futuras investigações; e maior concentração de pesquisas sobre políticas públicas de inclusão na região sudeste do Brasil.
