George Mann. Theatre Lethbridge: A History of Theatrical Production in Lethbridge, Alberta (1885-1988)
Authors: O'Neill Patrick B.
Published: January 2021

During the formative years of the Association for Canadian Theatre History, its members recognized the need for establishing basic records of dramatic activity within communities. Most members believed that a series of local studies and performance calendars, detailing the theatrical history of various towns and cities across the country, would engender a true basis for investigating the larger patterns of Canada's cultural development. Unfortunately, few such studies were undertaken and fewer completed. If nothing else, Theatre Lethbridge reminds us of why the founders of the association placed such importance on the preparation of local studies and calendars of performances. Mann documents the history of theatre in Lethbridge, provides new insights into the cultural setting of theatre on the Prairies and within Canada, and challenges us to rethink some established beliefs and attitudes.
Academic Trouble: A Response to "This Discipline Which Is Not One"
Authors: Bennett Susan
Published: January 2021

In this last term (Fall, 1994), I had one of those experiences which reminded me of the complicated and often troubled relation between my own life "as an academic" and the field in which I claim some expertise. Perhaps it was the context-another role, this one comprising one aspect of the "service" component of my job-that made what Ric Knowles very carefully argues about the "dizzying range of very different disciplines" so powerfully troubling. As a member of the University of Calgary's President's Committee on Sexual Harassment (a group that works on both policy and education), I chaired a post-production panel for a special performance of the Alberta Theatre Projects staging of David Mamet's Oleanna. I listened to panellists talk about "the case"-as if what we had just watched were an actual experience of sexual harassment and where the university's policy and the actions of the individuals had contravened general practice; I listened to other speakers critique the structure of Mamet's play and his realization of "characters" as if their behaviors were somehow unrelated to what happens in the 'real world' (if the academy can be thought of in this way); I heard women from the community offer accounts full of pain about the kinds of violence against women's bodies, part of their direct experience of the world and taken for granted-indeed, exploited in this particular production; and, finally, I heard from two actors with the company that we were all overreacting: that this was theatre, that their job was to entertain us and our task to be entertained. All this analysis, they implied, was no good whatsoever since it wrecked the whole premise under which we were all in this particular space at this particular time.
Establishing a Theatrical Tradition: Prince Edward Island, 1800-1900
Authors: Peake Linda M.
Published: January 2021

Theatrical activity in Prince Edward Island can be dated to 1800 when the Charlotte-Town Amateur Theatre opened. Throughout the century, dramatic entertainment flourished in local performances, with professional touring companies arriving from the 1880s on. During the last two decades of the century, a group of theatre people seeking a retreat from the pressures of a New York winter season purchased land and founded the Fortune Bay Actor's Colony.
Anne Nothof, ed. Les Théâtres Professionnels du Canada Francophone: Entre Mémoire et Rupture Sous la Direction de Hélène Beauchamp et Joël Beddows
Authors: Nelson Ian C.
Published: January 2021

Le théâtre foisonne depuis longtemps au sein des communautés francophones hors Québec mais souvent dans un contexte où la lutte pour la survivance linguistique et culturelle est difficile. Dans les cas les plus difficiles, on est souvent à court de moyens pour atteindre un véritable professionnalisme dans la pratique théâtrale, bien que le théâtre hors Québec se soit généralement affranchi de cette image de la survivance. La mission communautaire a animée de nombreux créateurs et, dans les milieux urbains, une quête esthétique a motivé les efforts qui ont permis la naissance à la quinzaine de compagnies professionnelles et aux trois associations qui assurent la coordination de certaines de leurs activités: l'Association des compagnies de théâtre de l'Ouest (ACTO) fondée en 1999, l'Association des théâtre francophones du Canada (ATFC) fondée en 1984 et Théâtre Action (TA) fondé en 1972, en Ontario. Le Cercle Molière de Saint-Boniface existe, certes, depuis 1925, mais les autres compagnies qui oeuvrent aujourd'hui n'ont été établies qu'à partir de 1967. Malgré la jeunesse de ces compagnies, on s'inquiète parfois que l'histoire récente soit oubliée. Par exemple, Richard Thérieux explique que pour le 25e anniversaire du Théâtre la Seizième «personne au conseil d'administration ne pouvait raconter l'histoire» (184). Heureusement, le théâtre professionnel émergent se trouve étudié et expliqué dans ce recueil de la collection sociologique «Roger-Bernard» des Éditions du Nordir. Hélène Beauchamp et Joël Beddows expliquent en préface que les textes rassemblés se veulent «une lecture historique des événements, une lecture doublée d'analyse» (9).

O caminho da saúde sexual e reprodutiva na América Latina: uma análise temporal de indicadores para cinco países da Região
Authors: De Oliveira Bonifácio Gabriela Marise , Rodriguez Wong Laura Lídia
Published: January 2021

Apresenta-se a evolução do padrão reprodutivo de diferentes países da América Latina com níveis de fecundidade distintos, procurando entender se a Região está tornando-se mais homogênea em termos de comportamento reprodutivo. Utilizam-se como indicadores desse padrão: proporção de mulheres sem filhos, idade mediana à primeira união e ao ter o primeiro filho e presença de filho ao usar contracepção pela primeira vez. Os dados provêm de pesquisas sobre saúde reprodutiva de Brasil, Colômbia, El Salvador, Peru, e República Dominicana em três pontos no tempo: décadas de 80 e 90 e início dos anos 2000 segundo idade e escolaridade. Os resultados mostram que as diferenças estão diminuindo entre os países com a proximidade dos níveis de fecundidade, mas ainda permanecem brechas por escolaridade que sugerem ampliar-se dentro dos países. Os resultados oferecem importantes insumos para entender os trajetos delineados por diferentes gerações nos países da Região no que se refere ao padrão reprodutivo.
Segregación residencial en la Región Metropolitana de Córdoba en el nuevo modelo de urbanización en Argentina: Censos 2001 y 2010
Authors: Molinatti Florencia
Published: January 2021

Córdoba, al igual que otras ciudades de Argentina y del mundo, expande su territorio más rápido que su población y como consecuencia su densidad bruta residencial ha caído un 1% anual en los últimos veinticinco años. En este contexto de expansión del entorno metropolitano, la construcción de urbanizaciones cerradas en la periferia se consolida como el uso de suelo predominante en este nuevo modelo de urbanización, donde predomina la polarización y fragmentación socioterritorial como consecuencia de la valorización del suelo urbanizable. Esta investigación tiene por objetivo analizar el fenómeno de la segregación residencial socioeconómica, a partir de la variable años de escolaridad promedio del jefe de hogar, en la Región Metropolitana de Córdoba en 2010, y las modalidades en las que ella opera en este nuevo modelo de urbanización; como así también indagar dicho fenómeno al interior de los municipios que componen este espacio metropolitano.
Lógica argumental de las políticas sobre envejecimiento y vejez en Uruguay: producción de sentido, tensiones y hegemonías
Authors: Berriel Fernando , Guidotti Gonzalez Carolina A.
Published: January 2021

En noviembre de 2016 fue aprobado en Uruguay el Segundo Plan de Envejecimiento y Vejez, para el período 2016-2019, que pretende avanzar en una perspectiva de integralidad y derechos de las personas mayores. Este trabajo presenta un análisis temático del plan, focalizándose en identificar su lógica argumental, los principales enfoques en los que se funda, así como los significados que le atribuye al envejecimiento, la vejez y las personas mayores. Se inicia con la definición de la formulación de políticas y de la lógica retórica expresada en documentos escritos en tanto prácticas sociales productoras de realidad. Complementariamente, se analiza el nivel de interdisciplina expresado en los lineamientos del plan, es decir, la mayor o menor hegemonía disciplinaria sobre la que fue erigido. De ello se desprenden algunas consideraciones sobre el papel de lo disciplinar en la configuración de las políticas públicas sobre vejez y envejecimiento en el país.

Purpose. Investigation of deformation of the mouth of the degassing well depending on the deformation of the rocks around the preparatory work Methodology. The deformation of the mouth of the degassing well as a function of deformations of the roof rocks of the preparatory workings from which the well was drilled is considered. The dependence of the required depth of well sealing on the level of methane leakage and roof deformation is established. Results. It is experimentally proved that in the zone of active shifts behind the operating lava, where the main amount of explosive methane is released from the massif, the mouths of degassing wells change and the main types of irreversible deformations take place. With the distance from the contour of the preparatory production, the distance between adjacent concentrated deformations of the wellbore increases according to the logarithmic dependence, and these deformations are distributed according to the normal law. The average value of the concentrated deformation of the degassing well is in logarithmic dependence on the displacements on the contour of the preparatory work. The tensile deformation of the degassing well axis decreases with distance from the production contour into the array. Stratification of rocks leads to gas leakage and air suction, which reduces the efficiency of degassing. Permissible concentrated deformations of the degassing wellbore should not exceed its radius. Originality. The empirical power dependence of the required length of sealing of the degassing well on the allowable leaks and displacements of the roof of the preparatory workings from which the well was drilled is established. Practical value. Methods for calculating the required sealing depth of the degassing well have been developed and measures have been proposed to increase its stability, which increase the reliability of the degassing system as a whole and help increase the safety of underground coal mining.
Identifying Biomolecular Targets of the Anticancer Vitamin-E-δ-Tocotrienol Using a Computational Approach: Virtual Target Screening
Authors: Brooks Wesley H. , Pevzner Yuri , Pevzner Elza , G. Daniel Kenyon , C. Guida Wayne , Brooks Wesley H. , P. Malafa Mokenge
Published: January 2021

In recent years, evidence has mounted that a particular form of vitamin E (its δ-tocotrienol variant) may
have cellular functions beyond that of an antioxidant, a role commonly ascribed to the tocotrienol class of
compounds. In particular, numerous studies of δ-tocotrienol’s effect on cancer cells have identified it as a
potent anticancer and antitumor agent. However, this important revelation of potential therapeutic use poses
a series of new challenges, with arguably the most important being the elucidation of the precise mechanism
of action responsible for the anticancer activity of δ-tocotrienol. As an initial step to address this question,
we have used a computational tool, Virtual Target Screening (a molecular docking-based tool that identifies
potential binding partners for small molecules), to identify potential biomolecular targets of δ-tocotrienol.
Then, to gain a consensus as to the type of biomolecular entity that could be a target for δ-tocotrienol, we
utilized PharmMapper and PASS (a ligand-based chemoinformatic approach), and ProBiS (a tool that
analyses binding site similarities across known proteins). The results of our multipronged computational
consensus-seeking approach showed that such a strategy can identify potential cellular targets of small
molecules. This is evidenced by our identification of estrogen receptor-beta, a protein that has been
previously shown to bind δ-tocotrienol, which elicited a cellular response. This study supports the use of
such a computational approach as an initial step in target identification to avoid time-consuming, costly
large-scale experimental screening, greatly reducing the experimental work to just one or a few candidate
proteins.

The Aral Sea ecological disaster zone affects the health status of the population living in this zone. Biochemical parameters are indicators of the metabolic functionality of the body. The article presents data about the biochemical parameters of blood plasma in the male population living in the ecological crisis zone of the Aral Sea region. It is shown that when determining the majority of indicators of biochemical analysis within the physiological norm, there is a significant percentage of people with deviations in these indicators. Such data make it possible to assume about the factors that can affect the entire population and have massive manifestations. Certainly, these factors, include the negative impact of the environment on public health. An increase in gamma — glutamyltransferase was found in 41 % of the subjects, an increase in cholesterol in 38 % and an increase in triglycerides in 34 %. In the inhabitants of the Aral Sea, a correlation was found between the biochemical parameters of blood serum from the dose of chemicals. It was shown that long-term chemical load in the crisis zone of the Aral Sea region causes a deviation of protein metabolism. The results obtained indicate a significant percentage of people with metabolic stress in the process of adaptation to high chemical load.

Published: January 2021

It is presented a developed and constructed histophotometric complex for quantitative evaluation in relative units of content of deposited insulin and zinc in insulin-producing B-cells of histologic preparations of pancreas. The method previously used in similar studies was based on a visual assessment of the results of coloring the preparations, or a more accurate quantitative one under the conditions of using universal complexes, including a microscope with built-in measuring devices (photometers), the disadvantage of which is, as a rule, a very high cost limiting the possibility of their use. In addition, such complexes, in connection with their universality, are not suitable for studies related to the study of the functional state ofpancreatic B cells using highly specific histochemical methods for detecting insulin. The authors aimed to develop and create a study-oriented histophotometric complex of zinc and insulin in B cells, created using inexpensive components, which would help make quantitative analysis significantly more accessible to researchers working in the field of experimental diabetology.

Published: January 2021

Tourism is one of the main sources of income in many countries; even some states depend highly on the tourism industry at present. The main purpose of tourism business activities is to create competitive tourist products in the international market. Achievement of these aims requires the development of the governmental regulation system, support of the tourism industry, the usage of promotion methods of tourism products. The article presents and assesses the state of development of the most necessary tourism products for the devel-opment of the tourism industry on the example of Aksa-Jabagly Nature Reserve in Kazakhstan. The results of the study show that if we consider the development level of the four most important tourist products, such as accommodation, transportation, tourist attractions and electronic service, then we can say that the level of their development and the conditions for providing quality services to tourists are relatively good according to the three previous indicators. Based on the analysis of the quality of electronic services in the field of research (the main criteria: telephone signal, Internet speed, electronic tickets, etc.), we found that the level of e-service development in this region is low, despite the fact that Kazakhstan has the potential of using high-quality internet coverage in its current development status.

Published: January 2021

For living organisms, the main indicators are the average values are meteorological and hydrological parameters that determine the coverage of the survival of species. Currently, all research on the trend in the land-scape of river basins should begin with an analysis of climate change, which is currently undergoing rapid dynamic changes. The purpose of the study is to analyze the long meteorological trends of atmospheric humidity of the Nura River Valley. In the presented study, we analyzed the daily data of two weather stations of the Central Kazakhstan for the period from 1939 to 2019 within. The territory of the Nura river basin belongs to areas of pronounced insufficient moisture. A distinctive feature of the river is that the bulk of the annual flow takes place in a short period of spring flood (early April to mid-May, 4–5 months). Within the Nura river basin, reliable trends of significant changes in annual, semi-annual and seasonal amounts of atmospheric precipitation have been revealed. All identified trends have positive indicators. The results can be used for agricultural planning in the context of climate change in the Central Kazakhstan.

Published: January 2021

Currently, infections produced by the gram-positive bacteria S. aureusrepresent a significant healthcare burden throughout the world. This is attributed to the ability of this bacterium to develop antibiotic resistance and efficiently evade human immune response. Therefore, research effort of many scientific laboratories worldwide is directed toward characterization of the genetic organization and molecular mechanisms responsible for S. aureuspathogenesis. This report is aimed to describe the growing body of evidence related to our understanding of the genetic organization and molecular interactions of the S. aureus leukocidins with the human cells that play an important role in bacterial pathogenesis, and represent a significant healthcare burden. Understanding of the genetic organization linked with additional mechanisms responsible for the realization of toxic potential, can help us to develop a better personalized approach for therapy against S. aureus infections. Thus, improved understanding of the molecular interactions betweenS. aureusleucocidins, and cell surface receptors may lead to the development of the alternative anti-microbial agents, that either independently or in combination with the current antibiotic treatment regimens will be used as an effective treatment strategy in clinic.

Статья посвящена истории, принципам и методам геоботанического исследования территории Северного (Степного) Казахстана и степной части мелкосопочника. Исследуемая территория Казахстана занимает большую площадь, и ботанико-географические исследования с дореволюционного периода продолжаются по сегодняшний день. Благодаря этим работам появились многотомные труды, создавались карты. Авторами приведена таблица, отражающая системный анализ проведенных работ по геоботаническому районированию территории Казахстана в составе СССР по работам разных авторов. Но, несмотря на это, данная территория нуждается в более локальном геоботаническом районировании, так как современная наука требует более тщательного, детального подхода во флористическом районировании. Хотя флористическое и геоботаническое районирования имеют различия по принципам работы, оба подхода сочетаются при разработке комплексного или синтетического ботанико-географического районирования. Каждый вид районирования зависит от природных условий, соответственно для проведения таких работ нужен системный анализ почвенного покрова, климатических условий, гидрологического характера и т.д. В статье дан анализ периодам исследования территории, принципам проведенных работ, также более детальное описание растительности ГНПП «Буйратау» по подзонам, в зависимости от физико-географических условий.

В статье приведен обзор современного состояния изученности рябчика Карелина (Fritillaria karelinii(Fisch. ex D. Don) Baker) из сем. Liliaceae по литературным, гербарным и материалам полевыхисследований, проведенных в марте 2020 г. на территории Алматинской области. На их основанииописаны природные популяции, выявлены особенности распространения на юго-востоке Казахстана изучаемого вида, луковицы которого в последние годы стали объектом стихийной и хищнической заготовки на территории Алматинской области с целью экспорта сырья в Китай. В китайской медицине их используют для получения противокашлевых и отхаркивающих средств. По литературным данным, у ряда видов рябчиков удалось выявить антигипертензивное, антиноцицептивное (обезболивающее), противовоспалительное, седативное и противоопухолевое действия, обусловленные наличием стероидных алкалоидов. Анализ коллекций гербарного фонда Института ботаники и фитоинтродукции свидетельствует о широком распространении изучаемого вида на территории Казахстана, около половины образцов которого собрано на юго-востоке Казахстана. Даны фитоценотическая и морфометрическая характеристики, а также картосхема расположения выявленных на территории Алматинской области ценопопуляций F. karelinii. Сравнительный анализ морфометрических показателей рябчика Карелина из трех популяций свидетельствует о том, что илийская популяция изучаемого вида характеризуется благоприятными экологическими условиями и отсутствием лимитирующих факторов. В то время как Капшагайская и Богетинская популяции подвержены сильной антропогенной нагрузке и нуждаются в охране.

Published: January 2021

Nowadays, using plant extracts and infusions as protectors against the impact of heavy metals, the molecular mechanisms, protective and adaptive reactions of plants are studied. The purpose of this article was to study the protective properties of beetroot seeds infusion in acute and sub-acute poisoning of rats with cadmium nitrate. For this experiment, we used 50 male rats. The animals were exposed to Cd nitrate, with an initial weight of 180 ± 30 g. The first groups of rats were injected with cadmium nitrate at a dose of 0.1 g/L intraperitoneally, the second groups received a 0.01 % solution of cadmium nitrate, 1 mL, 5 days a week, orally for 10 and 24 days. General blood tests and biochemical parameters in rats were investigated. By biochemical parameters, we determined liver enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, glucose, urea, creatinine, and total protein. The mean ± SEM values were calculated for each group to determine the significance of the intergroup difference. Each parameter was analyzed separate-ly using the one-way analysis of variance (ANOVA) test. To determine the difference between groups, Stu-dent’s «t»-test was used. Studies showed the presence of variations in the parameters of leukocytes, erythrocytes and platelets depending on the period of days of poisoning and biocorrection. There were small changes in the content of urea, creatinine, and protein, which were not reliably confirmed.

Published: January 2021

Abstract. The physical and mechanical characteristics of highly filled slag cements modified by the organic-mineral complex of LLC “MC Bauhemi” have been investigated. As a result of optimization, the area of permissible concentrations of organic-mineral additives was established according to the maximum criteria for the timing of the beginning and end of setting and strength in compression at the age of 7 and 28 days. It is shown that the expansion of the beginning of setting and its end is positively influenced by the presence of the plasticizer MC-PowerFlow 2695 from 0.43 to 0.8% and the organic-mineral complex Centrilit NC and Centrilit Fume SX in an amount from 3 / 5.25 to 5.2 / 7%, that with a simultaneous increase in the slag content from 50 to 70% in the composition of Portland cement, the start-end time of setting increases from 225/250 to 320/330 minutes, which is 1.3 / 1.5 times higher than similar indicators of no additive Portland cement. It was noted that at the age of 7 and 28 days, the introduction of an organic-mineral complex of the composition MC-PowerFlow 2695 from 0.28 to 0.64%, Centrilit NC from 4.23 to 7% and Centrilit Fume SX from 3 to 7% and at the content of GDSH in the amount of 50 and 70% contributes to the production of an artificial stone of the M500 brand with compressive strength in the range of 47 / 52.8 and 46/48 MPa. Using the method of superposition of response functions, the optimal area of permissible concentrations of the components of the Bauhemi organic-mineral complex, affecting the stated criteria, was determined when the slag content in Portland cement was 50 and 70%, namely: 0.6% MC-PowerFlow 2695, 5% Centrilit NC and 5 % Centrilit Fume SX. Further research will be aimed at studying the effect of this complex on the physical and mechanical properties with a slag content of 50 and 70% in the composition of Portland cement.

Abstract. In the 1950s and 1960s of the 20th century a lot of one- and two-span bridges with a span of 4-6 m were built on public roads on the territory of the former USSR. The paper describes the features of the design and construction of small four-hinged reinforced concrete bridges on lightweight supports of engineer Slovinsky system. The experience of surveying small bridges shows that in the context of a limited funding, compared to other types of bridges, maintenance and operation of these bridges does not get enough attention. There are relatively low material losses from their destruction and it is possible to restore them fairly easily. Therefore, many of them have a large number of defects and are in a poor physical condition. The purpose of the work is to draw attention of owners to the problems of small bridges using a specific example, as well as to present effective constructive solutions for the reconstruction of a small four-hinge bridge. These design solutions are developed on the basis of the research and development in Lviv National Polytechnic University and include the use of a reinforced concrete cover slab. The slab has been frequently used in other bridge reconstruction projects and proved its technical and economic efficiency in practice. The article gives characteristics of the bridge, the technical state of its structures, the main defects and damages, as well as the characteristics of the stream and its influence on the condition of the bridge. The design solutions for widening and strengthening the small bridge of the Slovinsky system can provide operational performance and consumer properties in accordance with the requirements of the current design standards for new bridges. These standards are able to ensure the service life of the reconstructed bridge.

O emprego de recursos tecnológicos computacionais pode ser considerado como um dos principais meios propulsores para diversas transformações ocorridas na sociedade. Em se tratando de gestão organizacional, é quase impensável que empresas busquem atuação diversificada sem o apoio de ferramentas computacionais. Neste sentido, é consenso que a correta utilização de Sistemas de Informação tende a contribuir positivamente para o gerenciamento de processos de negócios. Este artigo objetiva apresentar como foi o processo de construção de um software cuja premissa inicial seria contribuir para a informatização de processos internos e com a gestão de um setor de Assistência Estudantil, no caso do IFMG – Campus Bambuí. Os aspectos teóricos relacionados com esta pesquisa estão baseados nos conceitos de Sistemas de Informação e inovação tecnológica na gestão pública. O gerenciamento das informações deste setor pesquisado era feito apenas com o uso de documentos de texto e planilhas eletrônicas, dificultando sobremaneira a integração de dados. A pesquisa foi desenvolvida entre o segundo semestre de 2018 até o final de 2019. As etapas para a produção do software tiveram como base a adaptação de propostas da metodologia ágil Scrum, com vistas a gerar e disponibilizar um produto final com funcionalidades aderentes às necessidades do público em questão. Após a implantação do software foi possível notar que os processos de tomada de decisão dos gestores passaram a contar com o importante auxílio de informações geradas pelo sistema. O compartilhamento de informações entre os servidores públicos também foi facilitado. Por fim, a informatização do processo de registro de frequência dos estudantes residentes na Moradia Estudantil do campus otimizou o trabalho dos servidores públicos do setor, especialmente no que se refere à manutenção dos dados que, até então, era feita exclusivamente em papel.

O presente trabalho apresenta um sistema embarcado para o controle de posição de um robô paralelo com aplicação para acabamentos mecânicos. Anteriormente a máquina operava através do suporte computacional utilizando um dispositivo de alto custo. Dessa forma, com a substituição do aparato de processamento, sem a perda qualitativa, é possível estimar uma maior acessibilidade ao sistema concebido. Foi selecionada para a realização do trabalho a plataforma de software livre Arduino Due. O dispositivo controlado possui três bases manipuladas, com 300 mm de curso útil. Cada base é acionada por um motor de corrente contínua (CC) e um encoder, com resolução de 400 pulsos por volta. É utilizada a técnica de controle PID, com base no método Ziegler-Nichols de definição paramétrica. Para a melhor visualização, de forma gráfica, e definição dos dados empregados no sistema, desenvolveu-se um programa supervisório por meio da linguagem Java, que permite ao usuário definir os ganhos proporcionais, derivativos e integradores, bem como visualizar em tempo real a resposta sistemática perante aos parâmetros aplicados. Ao término do trabalho, pode se verificar um erro atuante máximo nos carros de aproximadamente 2,86%, obtendo por fim um dispositivo mais barato, com eficiência compatível com a original.

Published: January 2021

The house dust mites are considered to be an allergen source and a main cause of allergic rhinitis and allergic asthma. House dust mites, their feces and other allergens which they produce are usually major constituents of house dust. Any stir in the air causes settled dust, and therefore allergen source found in it, to become airborne and thus easier to be inhaled by people, possibly causing different kinds of allergic reactions (sneezing, for example). In this paper, the correlation between common home activities (walking around, bed making, vacuuming etc.) and airborne dust concentration is examined. In order to do so, a novel Internet of things architecture is proposed that is capable of establishing that correlation. This proposed system not only collects dust concentration but it also visualizes it in an easy to understand and interpret way.
