Entre el desarraigo y la querencia. Jóvenes rurales y TIC en Uruguay. Una aproximación cualitativa.
Authors: Sánchez Vilela Rosario , Borjas Celeste
Published: January 2021

Os estudos sobre o acesso e o uso das TICs concentraram-se principalmente no campo urbano, enquanto a juventude rural quase não foi abordada em sua especificidade. Esta pesquisa propôs uma abordagem para a compreensão desse setor populacional no Uruguai a fim de contribuir para sua visibilidade no espaço público. Apresentam-se aqui os resultados do estudo qualitativo de um grupo de jovens rurais uruguaios, composto por alunos do ensino médio agrário da Escola Agrária de Montes. O percurso que propomos parte de um panorama geral sobre a inserção dos jovens na população uruguaia e o acesso às tecnologias de comunicação, bem como a problematização das categorias juventude e ruralidade. O desenho metodológico adota uma abordagem socioantropológica em busca de significados e não de impactos, por meio de entrevista qualitativa. A análise explora dimensões espaciais e temporais da vida cotidiana - tempos de lazer, estudo e trabalho -, sociabilidade, representações e imaginários sobre essas tecnologias e projeções sobre o futuro. Os resultados da pesquisa permitem identificar algumas chaves para compreender as necessidades deste grupo populacional. As relações que se estabelecem em torno das TIC são apresentadas de forma ambígua e conflituosa. Sua chave interpretativa reside em uma situação vital atravessada pela tensão entre a expectativa iminente de migração para a cidade e o desejo de retorno ao meio rural e familiar.
Knowledge selection in initial teacher education programmes and its implications for curricular coherence
Authors: Rusznyak Lee
Published: January 2021

There are a multitude of concepts and techniques that could be important for teachers tolearn during their initial teacher education (ITE), but indiscriminately including all of themwould result in an overcrowded and fragmented curriculum. Given the limited time for ITE,rational knowledge selection choices must be made if coherent programmes are to beoffered to prospective teachers. This paper explores the approaches taken to addressing thecritical challenges facing education in South Africa and the principles from knowledgeselection that arise from these approaches. Different conceptions about how best to addressthese challenges offer directed priorities to guide knowledge selection decisions for ITEcurricula. Examples of knowledge selection principles that variously promote conceptual orcontextual coherence are presented and analysed, and tradeoffs associated with each one areconsidered. Although some recontextualising principles are mutually incompatiable, othershave the potential to coexist. In a four-year qualification, where sequencing choices can bemade, there exists the possibility of introducing different principles at different timeswithout unduly compromising internal coherence. A challenge for those who design ITEcurricula is to design conceptually coherent and/or contextually responsive curricula fullyaware of the affordances and limitations offered by different recontextualising principles.
Fostering the employability of business studies graduates
Authors: Hollis-Turner Shairn
Published: January 2021

Higher education is under pressure to enhance the employability of graduates by ensuring that they acquire competencies that make them employable in the labour market. This research project investigated the contribution of higher education towards the employability of graduates within a business diploma programme. A Delphi approach was employed with the Delphi panel consisting of three types of professionals – employers within the corporate sector, academics in the field of business studies, and graduates with workplace experience in the corporate sector. Both quantitative and qualitative data were obtained from three rounds of surveys. The findings show that disciplinary knowledge of Information Administration, Business Administration, Communication and Personnel Management, and the simulation of workplace practices as well as work-integrated learning opportunities are significant to enhancing the employability of office administrators and office managers. These findings provided academics with the opportunity to make improvements to the curriculum to foster the employability of the graduates.
Diagnosis of a “Plague” Image: A Digital Cautionary Tale
Authors: Green Monica , Walker-Meikle Kathleen
Published: January 2021

This brief study examines the genesis of the “misdiagnosis” of a fourteenth-century image that has become a frequently used representation of the Black Death on the Internet and in popular publications. The image in fact depicts another common disease in medieval Europe, leprosy, but was misinterpreted as “plague” because of a labeling error. The error was then magnified because of digital dissemination. This mistake is a reminder that interpretation of cultural products continues to demand the skills and expertise of humanists. Included is a full transcription and translation of the text which the image was originally meant to illustrate: James le Palmer, Omne bonum, cap. “De clerico debilitato ministrante sequitur videre” (On Ministration by a Disabled Cleric), London, British Library, Royal 6 E. VI, vol. 2, fols. 301rb–302ra.
The Black Death and its Consequences for the Jewish Community in Tàrrega: Lessons from History and Archeology
Authors: Colet Anna , Xavier Muntané i Santiveri Josep , Ruíz Ventura Jordi , Saula Oriol , Subirà de Galdàcano M Eulàlia , Jáuregui Clara
Published: January 2021

In 2007, excavations in a suburb of the Catalan town of Tàrrega identified the possible location of the medieval Jewish cemetery. Subsequent excavations confirmed that multiple individuals buried in six communal graves had suffered violent deaths. The present study argues that these communal graves can be connected to a well-documented assault on the Jews of Tàrrega that occurred in 1348: long known as one of the earliest episodes of anti-Jewish violence related to the Black Death, but never before corroborated by physical remains. This study places textual sources, both Christian and Jewish, alongside the recently discovered archeological evidence of the violence.
Plague Depopulation and Irrigation Decay in Medieval Egypt
Authors: Borsch Stuart
Published: January 2021

Starting with the Black Death, and continuing over the century and a half that followed, plague depopulation brought about the ruin of Egypt’s irrigation system, the motor of its economy. For many generations, the Egyptians who survived the plague therefore faced a tragic new reality: a transformed landscape and way of life significantly worsened by plague, a situation very different from that of plague survivors in Europe. This article looks at the ways in which this transformation took place. It measures the scale and scope of rural depopulation and explains why it had such a significant impact on the agricultural infrastructure and economy.
Seals as Conceptual and Ritual Tools in Chinese Buddhism, CA. 600–1000 CE
Authors: Copp Paul
Published: January 2021

In medieval China, this article demonstrates, nearly all forms of seals and sealing—both physical and metaphorical—were translated to use in religious practice: tropes of identity and material transmission; multiple styles of wearing and impressing seals; and the many forms of physical matrix and impression. This article focuses on the place of seals within Buddhism in China, especially within a broad family of localized ritual practices centring on incantations, amulets, and other ritual techniques and objects. Reflecting Buddhism's history there more generally, its uses of seals were amalgams of local Chinese and imported Indic and Central Asian practices.
Empire and Caliphate in the Life of John of Gorze
Authors: Levin Natalie Dawn
Published: January 2021

The Life of John of Gorze tells the story of a monk who served as an envoy from Otto I to ʿAbd al-Raḥmān III in the 950s. It reflects the turbulent political context in which it was written during the 970s and fits into the imperial program initiated by Emperor Otto I nearly a decade after John's mission. The text's engagement with Arabic literary motifs positions John and the Ottonian emperors as significant figures in Mediterranean politics and reveals the Latin author's knowledge of these Arabic sources.
Meubles: The Ever Mobile Middle Ages
Authors: Emery Elizabeth
Published: January 2021

Medieval furnishings preserved in aristocratic estates and ecclesiastical institutions took on new life in the nineteenth century as the turmoil of the French Revolution reactivated their use value, transforming them into collectibles, fuel, or raw materials for new building projects. This essay relies on the taxonomies of reuse proposed by archaeologist Michael Schiffer to evaluate the preservation, recycling, and repurposing of objects such as medieval choir stalls, chests, and beds by conservators, architects, artists, and collectors Alexandre Du Sommerard, Eugène-Emmanuel Viollet-le-Duc, Albert Jacquemart, Victor Hugo, Pierre Loti, and Frédéric Spitzer. These prominent figures' repurposing of antique furniture mirrors nineteenth-century constructions of the medieval period itself.
Reflection
Authors: Smail Daniel Lord
Published: January 2021

This contribution responds to the many insights about reuse and recycling generated by the contributors to this collection. Patterns of reuse are well known in archaeological and material-cultural circles and have been defined by a taxonomy of practices. As this collection suggests, however, it can be rewarding to apply these ideas beyond the material domain, and to think how they might help us understand the lives and afterlives of ideas, representations, texts, and landscapes. To think about reuse in this expansive way highlights processes or patterns that we may have missed by thinking about reuse primarily in the domain of the material.
Agricultural Treatises in Eurasia before ca. 1500: The Iceberg Method, a Survey, and a Grand Hypothesis
Authors: Myrdal Janken
Published: January 2021

This article analyzes all extant agricultural treatises produced before the sixteenth century throughout Eurasia, in order to highlight their importance for the study of agricultural praxis, their significance for constructing a transnational intellectual history of the medieval globe, and their relevance for the development of pragmatic literacies. Such texts emerged both in China and around the Mediterranean before 200 BCE, and somewhat later in India, but few have been preserved and many are difficult to date. Thereafter, the medieval transmission of agricultural knowledge moved via several different regional trajectories and traditions, with Anglo-Norman England becoming a fourth and largely independent birthplace of the agricultural treatise genre during the thirteenth century. The proliferation of these texts becomes evident throughout Eurasia around 1000 CE and increases further from the fourteenth onward. Throughout this longue durée, the contents of these treatises reflect real changes in agricultural technologies, dominant crops, and climate.
The Nationalist Turn in Youth Culture
Authors: Feischmidt Margit
Published: January 2021

This paper points to an important turn in youth culture which underpins increasing radical-right political sympathies and a propensity to national belonging and dignity-seeking among the youth. Qualitative analysis of 14 focus group interviews conducted in Hungary proves that the desire for political engagement of a significant segment of youth who have positioned themselves in opposition to a globalized youth culture and the apolitical stance of their generation. Inspired by cultural theories in political sociology that are also applied in the study of youth, and working with qualitative methods, this paper investigates the cultural dimension of radical-right politics and youth culture. The paper states that new forms of nationalism play a major role in the radical right turn among the youth by emphasizing the role of a general sense of disempowerment and disillusionment and claims for collective dignity which are framed in a hierarchical and mythical discourse about the nation. The major claim of this paper in this regard is that the renewal of nationalism and the commitment to the far-right in Hungary are closely connected.
The Revitalization of Social and Civic Participation in Eastern Europe?
Authors: Margarit Diana , Rammelt Henry
Published: January 2021

In the context of recent global economic and political changes, trade unions were forced to find new discursive and organisational strategies, as well as new means of imposing their agendas. However, the form and configurations of protests in Romania have shifted significantly from the workers’ strikes of the 1990s to middle-class protests, often described as being founded on the interests of young people and mainly focusing on the quality of democracy. In this paper we explain the weakness of interaction and the absence of spillover effects between popular protests and trade union mobilization. We demonstrate that, despite the high level of social mobilization Romania witnessed in the period January 2017–July 2018, and arguably since 2012, trade unions and popular protests did not manage to build on each other’s mobilization efforts. Although the mass protests might have positively influenced opportunity structures, trade unions were not able to benefit from them. Therefore, rather than looking at opportunity structures, in this paper we propose to understand the incapacity to join forces through an analysis of the mobilization claims of both parties and of their internal characteristics, such as their participants (by emphasizing the active involvement of young people), and organizational features. We argue that the lack of interaction between protests and unions is to be explained by incompatible mobilization frames: whilst unions also opposed the reform of the justice system, their main focus was the pension system and tax reform – moreover, they addressed issues specifically associated with work; popular protests, on the other hand, mobilized young people almost exclusively around the reform of the justice system.
Role of upper respiratory tract fibroscopy in patients with cervical lymph node metastases from squamous-cell carcinoma without the primary tumor found
Authors: Krylovetskaya M. A. , Komarov I. G. , Kontsevaya A. Yu. , Malikhova O. A.
Published: January 2021

Background. The detection of primary tumor in patients with cervical lymph node metastases without the primary tumor found is very important, because its location often determines the treatment strategy. The study objective is to analyze the capabilities of upper respiratory tract fibroscopy for the detection of primary tumor in patients with cervical lymph node metastases from squamous-cell carcinoma without the primary tumor found.

Materials in methods. A total of 70 patients with cervical lymph node metastases without the primary tumor found, in whom cytological examination of biopsy specimens collected from cervical lymph nodes revealed squamous-cell carcinoma, underwent upper respiratory tract fibroscopy in N.N. Blokhin National Medical Research Center of Oncology between January 2017 and May 2020.

Results. In 24 out of 70 patients, fibroscopy helped to identify the primary tumor and collect biomaterial for morphological examination. Twelve patients were found to have oropharyngeal cancer; ten patients were diagnosed with nasopharyngeal cancer; and 2 patients had laryngopharyngeal cancer. Fifteen out of 24 patients had tumors less than 1.2 cm.

Conclusion. Upper respiratory tract fibroscopy is a highly effective method for detecting small asymptomatic tumors. It can be recommended for the examination of patients with metastases from squamous-cell carcinoma without the primary tumor found, if the primary tumor is believed to be located in the upper respiratory tract

Published: January 2021

The study objective is to assess functional and oncologic results of transhyoid approach used for surgical treatment of oropharyngeal carcinoma.

Materials and methods. Operative records, hospital charts and data from out-patient department of 55 patients (T1 – 6, T2 – 16, T3 – 19, T4 – 14) with oropharyngeal carcinoma operated via a transhyoid approach were reviewed. Postoperative period was reviewed for complications. All oncologic adverse events were registered with special emphasis on the rate of local recurrence. A univariate analysis with chisquare and Fisher’s exact test was used to check the correlation between tumor factors and surgical variables (complications, mode of reconstruction). The influence of tumor- and treatment-related variables (T stage, differentiation, perineural invasion, p16 status, depth of invasion, extension to the oral cavity, adjuvant treatment) on the rate of local recurrence was studied in the same way. The log-rank test was used to assess differences in survival curves. The data was compared with other series of patients treated with the same technique.

Results. Seventeen (30,9 %) patients developed 29 complications. There was 1 postoperative death. Five (9,1 %) patients required repeated operation. The mode of reconstruction (primary closure vs flaps) was a major factor influencing the rate of complications. Fifty (92,6 %) patients were able to resume oral diet with a duration of nasogastric tube feeding of 7–35 days. Three-year overall/disease-specific survival for the whole cohort were 47 and 51,1 %, for p16-positive (22 %) cohort – 65,6 and 87,5 %, for p16-negative (78 %) cohort – 40,6 and 46,8 %. Thirteen (24 %) patients developed a local recurrence. The rate of local recurrence was negatively affected by p16 negativity (p = 0,048), depth of invasion >10 mm (p = 0,044) and depth of invasion >15 mm (p = 0,003).

Conclusion. Transhyoid approach may be considered as a surgical option for treatment of oropharyngeal carcinoma with acceptable rate of complications.

Dermal toxicity of anti-cancer drugs apparent in patients with thyroid cancer. This side effect appears, in particular, in relation to increased administration of targeted anti-cancer treatment, especially tyrosinkinase inhibitors, towards various receptors of growth factors which are applied in the ethiopathogenesis of a tumor cell. Our article focuses on the dermatotoxity, designated also as skin reaction, which most frequently occurs in patients treated by tyrosinkinase inhibitors – sorafenib, vandetonib, cabozantinib and lenvantinib. High prevalence of dermatotoxity, reported by patients, treated with these drugs underscores the need for greater understanding of the pathogenesis and management of this syndrome.

Introduction.The main method of preoperative diagnosis of thyroid tumors and the identification of possible metastasis is a cytological examination of smears obtained by fine-needle aspiration biopsy. However, the cytological material of the lymph nodes may not be adequate, and the detection of metastases faces a number of difficulties. In our recent study, we described a variant of the molecular classifier that allows the detection and typing of malignant thyroid tumors by analyzing several molecular markers in cytological preparations.

The study objectivewas to assess the applicability of the developed method for the preoperative detection of metastases of papillary and medullary thyroid cancer in the lymph nodes of the neck lateral cellular tissue.

Materials and methods.A total of 86 cytological samples were used, obtained from individual lymph nodes of 62 patients who had a diagnosis – thyroid cancer. Samples were analyzed by real-time polymerase chain reaction regarding the preselected set of molecular markers: the BRAF V600E mutation, the normalized concentration of HMGA2, FN1 and SERPINA1 mRNA, 5 miRNAs and the mitochondrial/nuclear DNA ratio. The decision tree-based classifier was used to discriminate between benign and malignant samples.

Results.The previously described classifier, based on the analysis of the BRAF V600E mutation, the content of HMGA2 mRNA, 3 miRNAs and the mitochondrial/nuclear DNA ratio, revealed metastases of thyroid cancer with good specificity (98 %) but less sensitivity (83 %). Therefore, a new classifier was built, including three markers – HMGA2 and FN1 mRNA, and miRNA-375, which, with regard to the detection of metastases, showed good sensitivity – 93 % with a slight decrease in specificity (up to 96 %).

Conclusion.Thus, we demonstrated the possibility of preoperative detection of thyroid cancer metastases in the lymph nodes of the neck lateral cellular tissue by analyzing several molecular markers in cytological material.

Published: January 2021

Olga Balashova - art historian, kmbs and KAMA lecturer, art critic, deputy director for the development of the National Art Museum of Ukraine (NAMU) in 2017-2020. The interview was recorded in February 2020 by assistant professor Anna Kaluger (Chair of Art History, Taras Shevchenko National University of Kyiv). This interview was conducted as part of the Ph.D. research "The structure of art criticism in Ukraine at the beginning of the XXI century." The discussion will focus on the definition of art criticism in the Ukrainian art context and its disciplinary boundaries. Olga Balashova talks about her career path as art historian and critic, determining for her theoretical influences, the school of art history at NAOMA, and her research priorities within the study of the history of criticism. Part of the interview focuses on the methods of teaching criticism in the humanities in the context of the internetization of criticism and the loss of its usual disciplinary basis - the history of art. It will also discuss the genre classification of criticism at the level of objects of study, in particular: the portrait of the artist, curatorial strategy, or phenomenological study of artistic events. The final part of the interview focuses on options for constructing the history of criticism in Ukraine: both the history of resources and the history of authors, the history of interpretations, and the history of methodological approaches.

A lot of educational institutions are facing the problem in conducting the physical classes due to COVID-19 pandemic recently. Therefore, most of the medium of teaching has been changed from a face-to-face method to online teaching. These changes may create some challenges to the students as well as the teachers or lecturers. In fact, different learning methods have their own strengths and weaknesses. Therefore, this study aims to analyze the preference of E-learning method among the undergraduate students based on multiple criteria. This study determines the priority of decision criteria in the selection of learning methods among the undergraduate students using Analytic Hierarchy Process-VIseKriterijumska Optimizacija I Kompromisno Resenje (AHP-VIKOR) model. The decision criteria that considered in this study are quality management system, information quality, flexibility, learning and teaching as well as attractiveness. Besides, blended learning, distance learning, and e-learning are identified as the alternatives of the learning methods as well as the most preferred learning method is determined in this study. The results of this study show that the most preferred learning method among undergraduate students is E-learning, followed by distance learning, and finally blended learning. Flexibility, information quality, and quality management system are ranked as the top three influential decision criteria. The significance of this study is to determine the most preferred learning method as well as the most influential decision criteria in the selection of learning methods among undergraduate students with AHP-VIKOR model.

Published: January 2021

The current technological revolution must be harnessed to increase access to information and help communities in developing countries make informed decisions that can improve their standard of life. The purpose of this study was to develop an app that attempts to complement traditional media by improving access to timely and relevant information to enhance teaching and learning in deprived rural contexts. The process was guided by design science research methodology. The paper responds to three questions: the processes considered for effective development of apps in resource-constrained environments; the value of mobile apps in supporting teaching; and how mobile apps transform deprived rural institutions. As part of the design research, the rural-university community was engaged in the construction of an app enabling access to educational information, registration portals, fee balances, and coursework. The findings indicate that the app was useful, easy to learn, and provided utility to its users, which consequently transformed their university life. The paper concludes by arguing that in a deprived learning context, mobile apps have the impetus to bridge the rural-urban dichotomy and recentre rural contexts in a direction for sustainable learning.

Published: January 2021

In our previous study, we proposed socialized creation competency as an advanced media information literacy. The competency involves four pillars: socialized creation, collaborative creativity, a critical eye and building affordance. The characterisation of this competency consists of all the component processes that make up social capital in ICT society. In this study, we extracted a concrete example to explain the socialised creation and to promote the sustainable development of society. The case we investigated was one in which civic IT engineers collaborated to develop program codes for a COVID-19 website. We collected and analysed related documents and communication records on Twitter. The results provided a deeper understanding of the importance of collaboration among diverse citizens, IT engineers, corporate workers and members of public sectors. Those players worked using a new style of production regarding Civic Tech and GovTech. Their activities blurred the borders of various organisations. Online services, GitHub, and other SNS were used for both creation and opinion exchanges, and emerging heterarchical communication was interrelated. The creators accepted the engagement of any citizen to vet opinions for purposes of improving the website. Records demonstrated the substantial potential for the needs of advanced MIL competency to understand civil society and collaborative creation by the public sector and citizens.

Authors:   Department of Business Administration at the National Chia-Yi University, Taiwan, Lee Hung-Wen
Published: January 2021

The purpose of this research article is to investigate the correlation among organizational socialization, job stress, and psychological contract based on employees’ viewpoint. Convenience sampling is used in this study. The questionnaires were distributed to employees in different organizations. Total number of questionnaires distributed was 380; 285 returned and 25 invalid. Total number of valid questionnaires is 260, total 68% valid returned rate. Questionnaire survey and multi regression were used for analysis. The findings include: Job stress is negatively influenced by organizational socialization. Psychological contract is negatively influenced by job stress; psychological contract is positively influenced by organization socialization; job stress plays a role of mediating effects between organizational socialization and psychological contract. In sum, employees’ psychological contract is indeed influenced by organizational socialization and job stress. Based on the result, employees’ future expectation has significant influence on job stress and psychological contract, indicating if a company can provide a clear view of their future, reasonable promotion and reward mechanism, complete and clear rules or norms, employees’ insecurity and uncertainty about their future will be lowered, their negative feelings caused by job stress will be reduced, and they will have higher organizational commitment. In the long term, the interaction between employees and the organization will be more positive, consistent, and harmonic.
Toilet Paper Thrones and Heated Tweets: Applying Moral Panic and Social Network Theory to Responses Over Panic Buying during COVID-19
Authors:   Acton-Boxborough Regional High School, 36 Charter Road, Acton, MA 01720, USA, Li Shuxuan (Elizabeth)
Published: January 2021

Social networks string everyone together. In the world affected by the COVID-19 pandemic, residents left their houses less often and maintained their connections online. Preparing for longer periods at home, some customers stockpiled supplies, the most discussed of which being toilet paper. When internet users came across videos of empty store shelves and people boasting about the amount of toilet paper they obtained, public contempt exploded over these supposed “panicked buyers.” From February to May of 2020, patterns of reaction against panic buying matched the description of a moral panic as presented by sociologist Stanley Cohen. The media is an agent of contagions in a social network. During COVID-19, news headlines often detailed shortages of supplies around the world. Meanwhile, social media became a platform for videos of stockpiling consumers, like those who built thrones out of toilet paper boxes. These behaviors from the media further escalated a small issue of temporary toilet paper shortage to almost a national emergency, while drawing attention away from shortages of crucial medical supplies and test kits.
Assessment of adenoid hypertrophy with clinical grading versus radiology and endoscopy- A cross-sectional study
Authors: O Sadhana , Jyothirmai A.S.L , Satish Chandra T , Murthy P.S.N
Published: January 2021

Chronic adenoid hypertrophy is the most common presentation seeking medical advice in pediatric age group. Evaluation of adenoid enlargement is usually done clinically, but its reliability in young children is questionable. Although various diagnostic procedures have been proposed to diagnose adenoid hypertrophy, there is poor concordance on the ideal method by clinicians. The purpose of this study is to corroborate a clinical grading that could guide the clinicians in accurate diagnosis of adenoid hypertrophy and to warrant the cases needing adenoidectomy and to calibrate this clinical grading with endoscopic and x-ray findings.

A cross-sectional study was conducted in a tertiary health care among 60 children aged between 3-14 years who presented with signs and symptoms of chronic adenoid hypertrophy are evaluated with clinical grading, endoscopy, lateral neck x-ray, and findings were documented. The proposed clinical grading comprised of nasal and paranasal symptoms, ear complaints, craniofacial abnormalities, and sleep disturbances.

The statistical analysis was done with Pearsons Chi square test and the correlation between endoscopic and clinical grading is highly significant (p=0.0006), and there is also a strong correlation between radiological and endoscopic grading (p=0.0003), the correlation between clinical grading and radiological finding (p=0.04) was significant.

Clinical grading was found to be a reliable parameter for assessment of the severity of adenoid hypertrophy. Though x-ray is a convenient procedure for diagnosing adenoid hypertrophy, it was found to be less accurate in assessing the clinical implications when compared to endoscopy.

Published: January 2021

Ground Magnetic measurement was carried out with the aim of delineating the subsurface structures on Dala hill, Kano State. Total magnetic intensity data were acquired using the SCINTREX proton precession magnetometer along closely spaced traverses. The acquired total magnetic intensity data were reduced and plotted using Golden Surfer software to produce the 2D and 3D surface maps for visual inspection. Five profiles AB, CD, EF, GH and IJ were selected for forward modelling using Mag2dc software to give detail information about the causative body parameters. The depths of these bodies from the surface fall in the interval 0.0 m to 8.5 m. The high magnetic anomaly field ranges from -21,752 to 47,205 nT which suggested area of iron occurrences. The study categorized the identified major anomalous features into two: the shallower bodies which penetrated down to a maximum depth of 67.3 m were inferred to be disturbed sediments, fire pits and kilns; whereas the rest, the deep-rooted features with greater depth of penetration reaching up to 193.2m, have high susceptibility range of up to 7.3 SI units, were interpreted to be intrusive ferromagnetic bodies. The findings of the study were in close agreement with recent archaeological findings about the hill.

Population in Adamawa Plateau faced to borehole failure and return to alternative water supply structures (wells and catchments) with a doubtful quality. This study was carried out to highlight the location of aquifers, their hydrodynamics characteristics and groundwaters quality in Mbakaou locality, which belong to the Adamawa Region. Combination of geological and geoelectrical surveys at 10 stations, with hydrodynamic study of 4 boreholes were carried out to characterize aquifers. Hydrochemical analysis of 10 waters samples has been done to determine physico-chemical water quality and origin of waters mineralization. Geological studies show that basement rocks, which constitute fractured aquifers, consists of a large assemblage of granitoid. Geophysics and drilling data highlight superficial aquifers located between 2 and 17 m and fractured aquifers located between 11 and 74 m, with resistivity ranging from 50 to 671 Ω.m. The borehole have yield varying between 2.80 and 5.14 m3/h. Transmissivity and permeability ranging from 10-6 to 10-5 m2/s and 10-7 to 10-6 m/s respectively, indicating that aquifers are semi-permeable. Waters are of good quality compared to WHO norms and weakly mineralized (35 to 247.9 mg/l). Piper diagram show that calcium and magnesium bicarbonate facies is dominant. Mineralisation of water is mainly influenced by water-rock interaction through silicate weathering.

Zinc coatings are widely used to protect steel goods from corrosion. The physics of methods of zinc applying to steel determines the coating morphology. Hot-dip zinc and thermodiffusion coatings are produced on steel by a diffusion mechanism and contain intermetallic phases according to the Fe-Zn diagram; however, they have different phase morphology, corrosion resistance, and consequently, different operating corrosive media. Thermodiffusion coatings have the highest corrosion resistance. However, their applying technique imposes a restraint on the dimensions of goods due to the small size of a chamber, and it requires much more time (several hours) compared to hot-dip zinc coatings applying for several minutes. In this respect, the authors suggest using the diffusion annealing of hot-dip galvanized goods to produce the entire intermetallic structure of the coating. The goal of the paper was to study the influence of the diffusion annealing modes on the microstructure and properties of hot-dip zinc coatings. The study showed the changes in the microstructure and elemental composition of the zinc coating phases as the result of soaking at the temperatures of 500 and 600 °С for 5 and 10 minutes. The authors researched the influence of annealing modes on the porosity of a coating and its microhardness. The coatings were quickly tested for corrosion resistance in the initial state and after thermal treatment. As a result of diffusion annealing, zinc coating becomes completely intermetallic, more homogeneous; its chemical composition becomes uniform. The study identified that to obtain the balance of physical-mechanical and technological properties, it is recommended to use the diffusion annealing mode with a temperature of 500 °С and soaking in a furnace for 5 minutes.

The study objective was to analyze the change in the morphology and microhardness of the AK5M2 alloy irradiated by an electron beam in various regimes. The authors modified the Al-5wt%Si alloy surface by an electron beam in the modes differed in the electron beam energy density (10, 20, 30, 40, and 50 J/cm2) and pulse durations (50 and 200 μs). The study identified that at electron beam parameters of 30 J/cm2, 200 μs, and 50 J/cm2, 50 μs, the maximum increase in microhardness to 860 MPa and 950 MPa was observed for each of the regimes, respectively. The microhardness value of the cast alloy was 520 MPa. Numerous micropores and microcracks characterize the irradiation surface morphology at beam parameters of 30 J/cm2, 200 μs. The material shrinkage during its high-speed crystallization can cause the formation of micropores. It is possible to assume that the generation of tensile stresses in a surface layer resulted from high cooling rates of a surface layer of the material from the molten state causes the formation of microcracks. The irradiation mode of 50 J/cm2, 50 μs leads to the complete dissolution of intermetallic and silicon particles in a surface layer; the crack density per surface area unit of the sample decreases against the regime of 30 J/cm2, 200 μs. The surface layer is characterized by the structure of high-speed cellular crystallization with the sizes of 500 to 800 nm formed in the volume of the grains that may cause an increase in the strength properties of the material.

Çalışmada akıllı ulaşım sistemleri için parametrik ve parametrik olmayan tahmin yöntemlerin kısa zamanlı trafik tahmin performansları incelenmiş ve tahmin değerlerinin sinyalize kavşakların devre süresine ve performansına olan etkisi araştırılmıştır. Kavşakta gözlemlenen trafik verilerine bağlı olarak gecikme sürelerinin iyileştirmesi ve kavşak bekleme sürelerinin azaltılarak, kavşak performans iyileştirmesi amaçlanmıştır. Çalışma bölgesi olarak Denizli ilinde yer alan Mimar Sinan kavşağı seçilmiştir. Kavşağın yaklaşım kollarında bulunan sensörler yardımıyla elde edilen veriler, veri setleri olarak düzenlenmiştir. Oto-regresif entegre hareketli ortalama (Auto-Regressive Integrated Moving Average-ARIMA) ve yapay sinir ağları (YSA) yöntemleri ile kısa zamanlı trafik tahminleri yapılmıştır. Tahmin sonuçları Webster yöntemi kullanılarak kavşak devre süresi optimizasyonu yapılmıştır. Optimum devre süresi ve yeşil süreleri hesaplandıktan sonra Webster gecikme metodu ile kavşak yaklaşım kollarının ve kavşak genelinin gecikme değerleri hem ARIMA yönteminden elde edilen hem de YSA yönteminden elde edilen tahmin sonuçları karşılaştırılmıştır. Kısa zamanlı trafik tahmininde YSA yönteminin ARIMA yöntemine göre daha başarılı olduğu görülmüştür.
