Validating improved-MODIS products from spectral mixture-Landsat snow cover maps in a mountain region in southern Spain
Authors: Pimentel Rafael , Marín Carlo , De Gregorio Ludovica , Callegari Mattia , Pérez-Palazón María J. , Notarnicola Claudia , Polo María J.
Published: December 2018

Abstract. Remote sensing is the only feasible data source for distributed
modelling of snow in mountain regions on medium to large scales, due to the
limited access to these areas together with the lack of dense ground
monitoring stations for snow variables. Observations worldwide identify snow
cover persistence together with snowfall occurrence as the most affected
variables by global warming. In Mediterranean regions, the spatiotemporal
evolution of the snow cover can experiment quick changes that result in
different accumulation-ablation cycles during the cold season. High frequency
sensors are required to adequately monitor such shifts; however, for trend
analyses, the Landsat time series constitute the only available source of
data, being their frequency low for this regime, especially when cloudy
conditions limit the available images. On the other hand, the MODIS daily
series provide more than 15 years of continuous snow maps, despite the
spatial resolution may pose a constraint in areas with abrupt topography;
several approaches have been done to improve their spatial resolution from
combining different information. This work presents a methodological approach
to validate the improved MODIS daily snow cover maps from Notarnicola et al. (2013a, b),
with 250 m spatial resolution, in Sierra Nevada (southern Spain),
from a reference data set obtained by spectral mixture analyses of Landsat TM
data by Pimentel et al. (2017b). This reference time series of fractional
snow maps, with 30 m spatial resolution, were validated from high resolution
local time series of snow maps obtained by terrestrial time-lapse cameras.
The results show a significantly high correlation between the two snow map
products both on a global and basin scales in the Sierra Nevada area.
Selected areas and time periods are shown to address the convergence and
divergence between both products and assess the development of a fusion
algorithm to retrieve daily Landsat-resolution snow maps on a long term
basis.
Linked thick to thin – skinned inversion in the central Kirthar Fold
Belt of Pakistan
Authors: Hinsch Ralph , Asmar Chloé , Nasim Muhammad , Abbas Muhammad Asif , Sultan Shaista
Published: December 2018

Abstract. The Kirthar Fold Belt is part of the lateral collision zone in Pakistan linking the Makran accretionary wedge with the Himalaya orogeny. The region is deforming very obliquely, nearly parallel to the regional S-N plate motion vector, indicating strong strain partitioning. In the central Kirthar Fold Belt, folds trend roughly N-S and their structural control is poorly understood. In this study, we use newly acquired 2D seismic data with pre-stack depth migration, published focal mechanisms, surface and subsurface geological data as well as structural modelling with restoration and balancing to constrain the structural architecture and kinematics of the Kirthar Fold Belt. The central Kirthar Fold Belt is controlled by Pliocene to recent inversion of Mesozoic rift related normal faults. Focal mechanisms indicate dip-slip faulting on roughly N-S trending faults with angles in the order of 45°, which are too steep for newly initiated thrust faults. The hinterland of the study area is primarily dominated by strike slip faulting. The inverting faults do not break straight through the thick sedimentary column of the post-rift and flexural foreland; rather the inversion movements link with a series of detachment horizons in the sedimentary cover, progressively imbricating the former footwall of the normal fault. Due to the presence of a thick incompetent upper unit (Eocene Ghazij shales) these imbricates develop as passive roof duplexes. Finally, the youngest footwall shortcut links with a major detachment and the deformation propagates to the deformation front, forming a large fault-propagation fold. Shortening within the studied sections is calculated to be on the order of 20 %. The central Kirthar fold belt is a genuine example of hybrid thick- and thin-skinned system in which the paleogeography controls the deformation. The locations and sizes of the former rift faults controls the location and orientation of the major folds. The complex tectonostratigraphy (rift, post rift, flexural foreland) alone with the strong E-W gradients defines the mechanical stratigraphy, which in turn controls the complex thin-skinned deformation.

A Picture is worth a Thousand Words: A Study on Millennial Women’s Curation of Self on Facebook Profile Pictures
Authors: Rajan Benson
Published: December 2018

La interacción humano-computadora funciona en una propiedad mixta (MR), y la imagen de perfil de Facebook es una de esas funciones de la MR (Rajan, 2018). Los usuarios de Facebook interactúan con las imágenes de perfil ya que son el primer componente del perfil de Facebook de un usuario. Este estudio muestra que las mujeres millenials (entre las edades de 18 y 25 años) cuidan y mercantilizan (Kasch, 2013) sus propias presentaciones en Facebook. El objetivo de las millenials es tener una identidad digital única mostrando conscientemente elementos como el atractivo, el estilo de vida y la ropa a través de imágenes de perfil. Las imágenes que utilizan buscan obtener, a menudo, una sensación de estado de celebridad evocado a través de las interacciones con los usuarios (me gustas, comentarios, etc.) con estas imágenes. Por otro lado, también son conscientes de que sus imágenes evocan una variedad de efectos entre sus usuarios. Esto incluye sentimientos de excitación sexual y el intento de otros usuarios de comunicar dicha excitación a través de mensajes sexualmente explícitos (verbales / visuales). Tal afecto, propiciado por el patriarcado, predetermina los patrones de auto-presentación y percepción de los cuerpos femeninos (Bordo, 1993). Este estudio utiliza una combinación de entrevistas cualitativas en profundidad y cuestionarios de encuestas de autoevaluación para comprender la curación detrás de la imagen del perfil de mujeres millenials en Bangalore (India). Este estudio realizó una encuesta a 117 mujeres millenials de entre 18 y 25 años de edad. Este artículo estudia el proceso detrás de la elección de determinadas imágenes de las mujeres, los propósitos a los que están dirigidos conscientemente y el poder de implicación afectiva del compromiso anticipado con estas imágenes. Se utiliza una versión modificada del framing de Goffman (1976) de los Anuncios de Género para analizar las fotos de los perfiles de Facebook de mujeres milenarias. Este estudio observó que las mujeres aplican procesos elaborados para lograr la imagen de perfil “perfecta”. La imagen de perfil tiene múltiples propósitos para el usuario, incluida la auto-afirmación de clase, la mercantilización del yo y la elección del yo en “redes sociales” en función de las expectativas de la sociedad. Estas millenials solían ser conscientes de que estas imágenes están incrustadas en una sociedad patriarcal y evocan respuestas afectivo-sexuales en otros usuarios.

Estudo epidemiológico de pacientes portadores de infecção do complexo bucomaxilofacial tratados no Hospital Universitário de Maringá: estudo retrospectivo ao longo de 8 anos
Authors: Farah Gustavo Jacobucci , Quinto José Henrique Santana , Farah Izabella Giannasi , Chistoffoli Marcelly Tupan , Luppi Caroline Resquetti
Published: December 2018

Infecções agudas bucomaxilofaciais podem ser condições clínicas graves e de ocorrência comum, caracterizadas pela disseminação do processo infeccioso a tecidos adjacentes e espaços faciais da região de cabeça e pescoço, podendo resultar em várias complicações, até mesmo em óbito, embora seja raro. Objetivo: realizar uma análise epidemiológica de infecções maxilofaciais, relacionando os dados ao tratamento instituído e à sua efetividade, bem como analisar dados referentes a idade, sexo, principais dentes envolvidos e tempo total de internação. Sujeito e método: foram analisados retrospectivamente 240 prontuários de pacientes admitidos no Hospital Universitário de Maringá com infecção odontogênica, atendidos pela equipe de Cirurgia e Traumatologia Bucomaxilofacial no período de janeiro de 2009 a janeiro de 2017. Resultados: a média de idade dos pacientes foi de 38 anos, com 57 mulheres e 54 homens. A média de temperatura de admissão foi38,5°C. A região mais acometida foi o ramo posterior da mandíbula, tendo uma média de duração de infecçãoe hospitalização de 6,1 dias. A principal conduta foi drenagem e antibioticoterapia, sendo que cerca de 13pacientes não precisaram desse tipo de intervenção, e um paciente evoluiu a óbito. Conclusão: com base nestes resultados e na literatura, infecções odontogênicas merecem atenção, pois podem ser fatais e requerem internação rápida e tratamento adequado. Esse, portanto, é um assunto de grande importância para o cirurgião-dentista, que exerce papel fundamental na prevenção e no tratamento. A resolução precoce ainda é a forma mais adequada para evitar complicações mais graves.
What Preservice Music Teachers Say About Educative Mentoring Before Student Teaching: A Focus Study Research Project
Authors: Abramo Joseph Michael , Campbell Mark Robin
Published: December 2018

In this study, we investigated 12 preservice music education seniors’ expectations and conceptions of their mentoring relationships with their cooperating teachers prior to their student teaching experiences. Data included responses from a survey and 3 focus group sessions. Using “educative mentoring” as a framework, we found that participants desired nurturing relationships where cooperating teachers served as critical friends and coaches. The seniors saw their relationships as providing normative practice; however, perhaps contradictorily, they also wanted cooperating teachers to provide emotional support and share personal stories. Additionally, they did not prioritize the connection of theory and practice during these relationships. This contrasts with previous research involving cooperating teachers, who saw their relationships as helping student teachers generate a personal style of teaching, creating an inquiring stance toward learning to teach, purposefully mitigating student teachers’ emotional responses to teaching, and explicitly connecting theory to practice. These differences in conceptions between student teachers and cooperating teachers might create areas of disagreements and misunderstandings. Based on these findings, teacher educators and university supervisors might give cooperating teachers direct philosophical guidance centered around educative mentoring, reconceptualize the role of supervisor toward coinquirer, and conceive of student teaching experiences beyond 1-on-1 mentorships.
Elma Lewis, Her School of Fine Arts, and Her Vision of Arts Education as Cultural Emancipation
Authors: Hope Sonya White
Published: December 2018

The purpose of this article is to present findings from my study of Elma Lewis and her philosophy that illuminate key relationships between effective arts education for Black students and contemporary music education practice. Critical race theory provides the defining lens through which I examine Elma Lewis, her work, and prominent turn-of-the-21st-century music education philosophy and practice. Of import are resonances and dissonances between Lewis’s views, the music education as aesthetic education perspective, and the music education as activity paradigm. I assert that Lewis advanced a philosophy of arts education as cultural emancipation (AECE) and contextualize her views within present-day education models of culturally oriented teaching and African-centered pedagogy. Scenarios envisioning 21st-century applications of AECE philosophy for music teaching and learning in diverse and dominant culture populations conclude this article.
Feasibility of Real-Time Mobile Phone Case Notification by Village Malaria Workers in Rural Myanmar: A Mixed Methods Study
Authors: Aung Pyae Linn , Pumpaibool Tepanata , Soe Than Naing , Kyaw Myat Phone
Published: December 2018

Malaria burden has markedly decreased in Myanmar and is on course for elimination by 2030. Interrupting of local transmission is essential, and timely notification within 24 hours of disease occurrence by frontline village malaria workers (VMWs) is a crucial initial component of timely follow-up by response teams. Here we studied the feasibility of real-time case notification using mobile phones among VMWs in the remote Banmauk Township, Sagaing Region, Myanmar. A structured quantitative and qualitative questionnaire was used for data collection after implementing the intervention for six months between May and October 2018. Ten VMWs from the National Malaria Control Programme (NMCP) in ten scattered villages from the township were randomly recruited and given one day of on-site training on reporting methods and how to use their own mobile phone. VMWs received 5,000MMK (approximately 3USD) per month remuneration. The baseline demographics of VMWs were not significantly different. Twenty-four out of 25 (96%) malaria patients were notified within 24 hours by the ten VMWs during the study period. All submitted information were said to be complete and correct. VMWs suggested the system as simple and acceptable despite some challenges. In the qualitative study, almost all VMWs were satisfied with the system and willing to use it in the future. This mobile phone reporting system is more efficient and easier to use than other more complicated online mobile applications. However, only a few indicators can be submitted using this approach and the system cannot be used in areas without network coverage.

Ants Are at the First Stage of the Notion of Zero
Authors: Cammaerts Marie-Claire , Cammaerts Roger
Published: December 2018

The notion of zero is rarely apprehended by animals. We examined if ants possess this ability in four experiments, each time using two colonies and operant conditioning. Ants succeeded in significantly comprehending the absence of a cue, but not as well as learning an existing cue, and they soon lost their learning. Ants thus have a sensory notion of the absence of an item, but not the abstract notion of a sensu stricto mathematical zero.
Wavelet Cross-correlation in Bivariate Time-Series Analysis
Authors: Souza Eniuce Menezes de , Félix Vinícius Basseto
Published: December 2018

The estimation of the correlation between independent data sets using classical estimators, such as the Pearson coefficient, is well established in the literature. However, such estimators are inadequate for analyzing the correlation among dependent data. There are several types of dependence, the most common being the serial (temporal) and spatial dependence, which are inherent to the data sets from several fields. Using a bivariate time-series analysis, the relation between two series can be assessed. Further, as one time series may be related to an other with a time offset (either to the past or to the future), it is essential to also consider lagged correlations. The cross-correlation function (CCF), which assumes that each series has a normal distribution and is not autocorrelated, is used frequently. However, even when a time series is normally distributed, the autocorrelation is still inherent to one or both time series, compromising the estimates obtained using the CCF and their interpretations. To address this issue, analysis using the wavelet cross-correlation (WCC) has been proposed. WCC is based on the non-decimated wavelet transform (NDWT), which is translation invariant and decomposes dependent data into multiple scales, each representing the behavior of a different frequency band. To demonstrate the applicability of this method, we analyze simulated and real time series from different stochastic processes. The results demonstrated that analyses based on the CCF can be misleading; however, WCC can be used to correctly identify the correlation on each scale. Furthermore, the confidence interval (CI) for the results of the WCC analysis was estimated to determine the statistical significance.
Higher order Markov Chain Model for Synthetic Generation of Daily Streamflows
Authors: Pereira A. G. C. , Sousa F. A. S. , Andrade B. B. , Campos Viviane Simioli Medeiros
Published: December 2018

The aim of this study is to get further into the two-state Markov chain model for synthetic generation daily streamflows. The model proposed in Aksoy and Bayazit (2000) and Aksoy (2003) is based on a two Markov chains for determining the state of the stream. The ascension curve of the hydrograph is modeled by a two-parameter Gamma probability distribution function and is assumed that a recession curve of the hydrograph follows an exponentially function. In this work, instead of assuming a pre-defined order for the Markov chains involved in the modelling of streamflows, a BIC test is performed to establish the Markov chain order that best fit on the data. The methodology was applied to data from seven Brazilian sites. The model proposed here was  better than that one proposed by Aksoy but for two sites which have the lowest time series and are located in the driest regions.

Police and prosecutorial appeals for information and wanted notices in a changing media landscape

Police and prosecution can appeal to the public for information to further their case. This requires a balancing exercise between the rights of the suspect (and other people involved), specifically the right to privacy and the interest of criminal investigations. Appeals for information and wanted notices require a medium as well. Also, in order for the appeal to be effective, other (news)media need to publish the appeal as well: it needs to be newsworthy and attractive for the public intended. Based on deskresearch, this article describes how an ever-changing media landscape and different media revolutions affect the appeals for information.
Onder een vergrootglas: de gevolgen van media-aandacht voor sociale professionals die werken met moeilijk bereikbaren
Authors: Suijkerbuijk Karlijn , de Jong Jeanet
Published: December 2018

Under the microscope: effects of media attention on social professionals who work with the hard-to-reach.

While media coverage supports citizens in exercising their democratic rights, developments in the media have turned organizations into glass houses. In this article we investigate what media attention and subsequent public reactions after incidents mean for social professionals who work with the so-called ‘hard-to- reach’. We draw on a practical example, literature and interviews. Media attention turns out to affect the public image of organizations and professionals and consecutively alters the long term public judgment. This results in professionals feeling powerless, unrecognized and pressurized. Professionals adopt different strategies to deal with the effects of media attention: resignation, defensiveness, caution and organizational blame.
Recht is niet alleen recht als er recht op staat

Recht is niet alleen recht als er recht op staat Over het (h)erkennen van de rechtskracht van private normen

Met het Achmea/Rijnberg-arrest van de Hoge Raad leek een doorbraak te zijn bereikt inzake de doorwerking van private regelgeving in het recht. Wanneer partijen het onderling eens zijn over de toepasselijkheid van bijvoorbeeld gedragscodes, toetst de Hoge Raad er ook aan zonder de juridische status ervan te beoordelen. De vraag wat te doen wanneer de relevantie van private regelgeving tussen partijen wordt betwist, blijkt echter een veel lastiger te nemen hobbel. Recente jurisprudentie over normalisatienormen toont aan dat het in zo’n geval buitengewoon complex is om te bepalen welke rechtsgevolgen aan private regels moeten worden verbonden. Wettelijke (h)erkenningsregels die de rechter behulpzaam kunnen zijn bij het kwalificeren en waarderen van private regels worden in die situatie node gemist. Hier ligt ook een taak voor wetgevingsjuristen. De vraag is alleen of één algemeen wettelijk kader voor uiteenlopende vormen van private regelgeving momenteel al haalbaar is. Werken met experimenteerbepalingen zou wel eens vruchtbaarder kunnen blijken te zijn. Dergelijke bepalingen zullen alleen werken wanneer wetgevingsjuristen, die ze moeten opstellen, zich eerst verdiepen in de schaduwwereld van private normen waarop deze bijdrage enig licht probeert te werpen.

Silver – soluble compounds. Determination in workplace air
Authors: Surgiewicz Jolanta
Published: December 2018

Silver compounds are generally insoluble in water. The few soluble silver compounds include, e.g. silver nitrate, silver fluoride, silver perchlorate. These compounds are used in chemical analysis and organic catalysis to produce other silver compounds (e.g. halides), explosives, antiseptics (in medicine ), mirrors; they are also used in classical photographic technique.

Soluble silver compounds are irritating and corrosive to the skin and mucous membranes of the eyes; they also cause permanent damage to the eyes and dysfunction of the respiratory and nervous systems.
Maximum admissible concentrations (MAC) for soluble silver compounds, expressed as silver, was set at 0,01 mg/m3.
The aim of the study was to develop a method for determination of concentrations of soluble silver compounds in the air at workstations in the range from 1/10 to 2 MAC value.
The developed method of determination consists in: taking an air sample on a membrane filter, washing out soluble silver compounds from the filter with deionized water and determination of these compounds as silver by flame (air-acetylene) atomic absorption spectrometry (F-AAS).
The method enables the determination of silver in the concentration range of 0.070÷2.00 µg/ml. The obtained silver calibration curve is characterized by a correlation coefficient R2 = 1.0000. The limit of silver detection (LOD) is 0.009 µg/ml, the limit of quantification (LOQ) is 0.027 µg/ml, and the recovery rate is 0.99.
The developed method allows the determination of soluble silver compounds in the air at workstations in the concentration range of 0.001÷0.028 mg/m3 (for an air sample with a volume of 720 l), which corresponds to 0.1÷2.8 times the MAC value.
The method is characterized by good precision and accuracy and meets the requirements of the European standard PN-EN 482 for chemical determination procedures.
The method for the determination of soluble silver compounds has been recorded in the form of the analytical procedure set out in the Annex.

Published: December 2018

The article dwells upon the peculiarities of remote piloted vehicles of on-board navigation complex. It is highlighted that total number of the remote-piloted vehicles have increased and as a result the question of their integration into common space with manned aircraft becomes urgent. It is possible only when specified quality of the remote piloted vehicle movement parameters have been determined, including accuracy and interference immunity. It has been highlighted that remote-piloted vehicle equipment is subject to stringent requirements for minimization of cost, mass and size characteristics and power consumption, which are often mutually contradictory, and their implementation in general leads to deterioration of accuracy. The problem of ensuring accuracy and noise immunity when using the general-purpose element base becomes urgent.

O ESTADO DE DIREITO “CONFRONTADO” PELA “REVOLUÇÃO DA INTERNET”!
Authors: Bolzan de Morais José Luis
Published: December 2018

A revolução tecnológica e seus impactos sobre a fórmula Estado (Liberal) de Direito impõem ao jurista a construção de um novo saber, o qual passa pelo reconhecimento dos limites genéticos e contingenciais que são peculiares ao próprio modelo Estado Liberal, bem como as projeções que se podem fazer a partir do “interregno” de suas crises. Com isso, rediscutindo a viabilidade do projeto constitucional moderno, propõe-se, utilizando da pesquisa bibliográfica, verificar as circunstâncias da experiência político-jurídica contemporânea tomando como referência a era da quantificação e a afetação dos direitos e liberdades fundamentais.

The article presents the results of strained hydrocarbons formation study during the catalytic transformation of methanol into hydrocarbons on zeolite H-ZSM-5. The formation of the following strained cyclic compounds was determined: 1,1-dimethylcyclopropane, 1,2-dimethyl-cyclopropane, 1,1,2-trimethylcyclopropane, 1,2,3-trimethylcyclopropane, 1,1,2,2-tetramethylcyclo-propane, 1,1,2 , 3-tetramethylcyclopropane. The non-stationary character of strained cyclic hydrocarbons formation with a pronounced hydrocarbons formation rate maximum and subsequent deactivation of the catalyst was found. The temperature effect on strained hydrocarbons yield was evaluated. Thus, with an increase in the process reaction temperature up to 400 °C, a maximum of strained hydrocarbons accumulation rate was achieved as 8-8.5 g(Hyd)/(kg(Cat)·h) on 350 h of reaction, and a further increase in the reaction temperature leads to a decrease in the strained hydrocarbons accumulation rate. The effect of the methanol feed rate on the strained hydrocarbons formation rate was also studied. An increase in the methanol feed rate from 0.02 ml/min to 0.16 ml/min results in increase in the strained hydrocarbons formation rate up to 37 g (Hyd)/(kg(Cat)·h). The article presents results of H-ZSM-5 physicochemical study used by ammonia chemisorption, nitrogen phisisorption, X-ray photoelectron spectroscopy. Physicochemical studies of catalyst samples after the methanol transformation process to form strained hydrocarbons showed a twofold decrease in the number of acid sites from 1.2 mmol(NH3)/g (sample) to 0.3 mmol (NH3)/g(sample) and a significant decrease in surface area of micropores from 294 m2/g for the initial sample to 16 m2/g for the sample after the reaction. The X-ray diffraction spectroscopy method showed that the composition of the catalysts H-ZSM-5 surface includes carbon, oxygen, silicon and aluminum. Carbon concentration was found to be 4.3 at.% on the surface of the initial catalyst. While the carbon concentration increases up to 14.1 at.% during the reaction. Also oxygen content on the catalysts surface decreases from 59.9 to 53.4 at%, silica concentration decreases from 35.5 to 32.1 at.%. The following indicates the formation of a carbon surface layer over the catalysts.

Published: December 2018

This work is continuation of synthesis researches of substituted macroheterocyclic compounds with 1,2,4-thiadiazole fragments. Data of synthesis of complexes with divalent d-metals (Ni, Co, Zn) on the basis of received earlier brominenitrosubstituted isothiadiazole three-unit product are presented. Complexes of BAB-type product consisting 1,2,4-thiadiazole and bromine-nitro-isoindole fragments were received by interaction 3,5-bis-[5(6)-bromine-6(5)-nitro-3-iminoizoindolin-1-ilidenamiino]-1,2,4-thiadiazol with acetates of d-metals in 2-ethoxyethanol at 100 ºC for 2 h. After the reaction the mixture was poured into water and precipitate was filtered and washed with 5 % ammonia, water and hot organic solvents (acetone, methanol, dimethylformamide, pyridine). Yield of target products was 18 – 28 %. The resulting complexes are dark brown powders with high solubility in alcohols, DMF, insoluble in water, dichloromethane and hexane. The structures of products were established by data of mass spectrometry, elemental analysis, UV-vis and IR spectroscopy. Data of MALDI-TOF mass spectrometry showed that complexes with metal of three-unit product with 1,2,4-thiadiazole fragment were isolated as monohydrate by analogy with literary for 1,3,4-thiadiazole. Data of atomic absorption analysis with good convergence of the experimental and calculated values confirmed monohydrate structure these products. These complexes of three-unit products will be used for synthesis of new various substituted macroheterocycles with 1,2,4-thiadiazole fragments.

INFLUENCE OF INTENSITY OF ULTRASONIC ACTION ON DEGREE OF PURIFICATION OF HALITE WASTE FROM CALCIUM SULPHATE IMPURITY
Authors: Nisina Olga E. , Lanovetskiy Sergey V. , Kosvintsev Oleg K.
Published: December 2018

When enriching potassium-magnesium ores, millions of tons of solid halite waste are formed, occupying vast areas and posing a danger to the environment. The main useful component of both these wastes is sodium chloride, which serves as a raw material in many chemical industries. The most common processing lines are the production of technical sodium chloride and technical sodium chloride solution. These products are intermediate and can be used in further chemical processes. Obtaining these products of the required quality is hindered by the presence of impurities, such as CaSO4, MgCl2, insoluble residues. The most undesirable impurity is calcium sulphate, the concentration of which can reach 3%. According to the literature sources, the optimal intensity of ultrasonic treatment of the water-dispersed medium was determined. The results of analyzes of phase and granulometric composition of solid halite waste (quarry salt and halite dump) are presented. The character of distribution of calcium sulfate impurity in crystals of halite waste is revealed. The article examines the results of the study of the influence of the intensity of ultrasonic treatment on the residual content of calcium sulphate in halite waste. Based on the results of the studies, the duration and intensity of the ultrasonic effect were established, at which the minimum concentration of calcium sulfate in the resulting halite raw material is reached. The obtained results allowed to establish the optimal regime of the process of cleaning the halite raw materials (intensity of ultrasonic action, processing time), which allow to significantly reduce the content of calcium sulphate during the mechanical cleaning stage and confirmed the potential possibility of using the obtained results for improving the technology of sodium chloride technical solution production, solid halite waste produced by potassium chloride "Uralkali".

Published: December 2018

Artiklen præsenterer et læringsdesign, som bidrager med at undersøge, hvordan man kan arbejde med digital dannelse igennem design af robotter og spil i en dansk højskolekontekst.I efteråret 2017 etableredes et teknologispor på Askov højskole. Teknologisporet består af to linjefag: ”Game design” og ”Robotter”. De to linjefag er forbundet af et fælles fag i programmering.Grunden til, at teknologisporet etableredes, var flerfoldigt. Vi vil gerne understøtte udvikling af de unge højskoleelevers digitale dannelse og herunder deres forståelse af hverdagenes teknologier. Artiklen præsenterer forskellige aspekter af digital dannelse i relation til eksempler fra teknologisporet.Derudover introducerer artiklen en tredelt model for digital dannelse fra en designvinkel. De tre niveauer: 1) Teknikken, som omhandler konkret anvendelse og forståelse af teknologien fx programmering, test og fejlfinding; 2) Praksisfællesskabet, som omfatter aktiv deltagelse i et fagligt fællesskab omkring design af ny teknologi; 3) Transformationslaget, som omfatter innovation og kritisk tænkning med udgangspunkt i ens personlige ståsted.
Processus de changement vers des pratiques plus inclusives : étude de la nature et de l’impact de conflits cognitifs
Authors: Bergeron Geneviève , Prud’homme Luc
Published: December 2018

Pour soutenir les changements inhérents à l’inclusion scolaire, plusieurs chercheurs démontrent l’importance d’offrir aux enseignants des moments leur permettant de rendre explicites et de remettre en question les croyances, les théories subjectives ainsi que les valeurs sur lesquelles s’appuient leurs pratiques. Le fait de vivre des déséquilibres sur certaines de ces dimensions permettrait ainsi d’entrevoir de nouvelles options pour soutenir le projet inclusif (Ainscow, 2005). Cet article s’appuie sur une analyse secondaire des résultats de deux recherches-actions-formations et vise à décrire la nature de conflits cognitifs vécus par des enseignants et leur impact sur le processus de changement. Les résultats mettent en évidence l’influence de conflits entourant les conceptions de la diversité, de l’apprentissage et de l’enseignement. Ces conflits aident les enseignants à être plus attentifs aux manifestations de la différence, à mettre à l’essai de nouvelles pratiques centrées sur l’apprentissage et à s’engager davantage dans le processus de changement.
