Study of Carbon Dioxide Diffusivity Through Sand
No full textThe purpose of this study was to measure the diffusion of carbon dioxide through sand and determine the viability of using cheap carbon dioxide sensors to measure diffusion. The data for the study was collected with the use of the K-30 and K-33 ELG carbon dioxide sensors in a diffusion cell set up made from PVC pipe fittings. The carbon dioxide concentration data was taken using software known as �Gaslab� and was interpreted using a program written by the author. The program was designed to run simulations of the column with given diffusivities, and use an optimizer to find the diffusivity that resulted in the least deviation between simulation and data; this diffusivity would then be taken as the diffusivity of the material in the column. Three series of experiments were run, the first quantified the rate of leaking within the column, the second validated the use of the column to measure diffusivity by measuring the diffusivity of carbon dioxide in air, and the third measured the diffusivity of carbon dioxide through dry sand sieved to ASTM 40-80 grain. The measured diffusivity of carbon dioxide through air matched the literature diffusivity and the diffusivity of carbon dioxide through the sand used was found to be (3.5 � 0.49) x 10-7 m2/s. These results suggest that the column set up was adequate for measuring the diffusivity of carbon dioxide through the sand sample, and could be used to measure the diffusivity of carbon dioxide or other gases through sands or porous materials.Chemical Engineerin
Enhancing Creative, Learning and Collaborative Experiences through Augmented Reality-compatible Internet-of-Things Devices
No full textThe "Maker Movement" is a cultural phenomena rooted in DIY culture, which stresses making devices and creations on your own rather than purchasing it ready-made. At the core of the Maker Movement, is the "Maker Mindset"; a collection of attitudes, beliefs and behaviors that emphasize the importance of creativity, experimentation and innovation in the learning process. Since the Maker Mindset embodies constructionist principles at its core that push makers to experiment and problem-solve by collaborating with fellow makers through hands-on activities, it can be said that these activities comprise of Creative, Learning and Collaborative experiences. While Internet-of-Things devices have long been used to enhance these activities, research pertaining to using Augmented Reality in tandem with IoT for the purpose of enhancing experiences core to the Maker Mindset is relatively unexplored. Three different systems were developed with the goal of addressing this -- MicrokARts, ShARed IoT and MechARspace. Each system focuses on enhancing one of the three core experiences through AR-compatible IoT devices, whilst ensuring that they do not require prerequisite knowledge in order to author AR experiences. These systems were evaluated through user studies and testing over a variety of age-groups, with each system successfully enhancing one core experience each through the use of AR-IoT interactions.</p
The role of housing in the formation of the living space of Tyumen dwellers in 1950-1960
No full textСтатья посвящена проблемам жилищного строительства и его роли в формировании жизненного пространства тюменцев. Автор исследует процесс трансформации городского пространства, его влияние на облик города и образ жизни населения. На основе сопоставления показателей, отражающих динамику роста частного и государственного жилого фонда и темпов увеличения населения, в работе делаются выводы о потребностях и реальной степени обеcпеченности населения жильем. В статье подробно изучается процесс расширения городского пространства, дается характеристика основным направлениям, способам и темпам развития областного центра. Автор детально описывает жизненное пространство тюменцев, останавливаясь на особенностях и оценивая уровень его комфорта для горожан. Статья основана на архивных материалах, впервые вводимых в научный . The article is devoted to the problems of house building and its role in forming the life space of Tyumen citizens. The author studies the transformation process of urban space, its influence on the image of the city and the population’s way of life. Having compared the indices of the dynamics of private and state housing stock growth and the speed of population growth, the author makes conclusions about the population’s housing needs and their actual provision with it. The article scrutinizes the process of urban space expansion, describes the main directions, ways and rates of the development of the regional centre. The author describes the living space of Tyumen citizens in details, pays attention to its peculiarities and evaluates whether it is comfortable enough for the citizens. The article is founded on the archival files never published before
Sanok hundred’s men (sotni) in the 15th century (to the question about the origin of royal servants in late-medieval Poland)
No full textСтатья посвящена одной из групп королевских крепостных слуг в Червоной Руси XV века. Сделан вывод, что саноцкие сотные были потомками древнерусских пленников, посаженных на землю . The article is devoted to the group of the royal bondservants in Red (Galician) Rus’ in the 15th century. The author comes to the conclusion that the Sanok hundred’s men (sothni) were the descendants of ancient Russian serf-captives settled on land (smerdy)
Выбор присяжных заседателей и экспертов-непрофессионалов в сравнительной перспективе: евразийский контекст.
No full textThis article compares (1) the qualification of jurors or lay assessors; (2) methods of listing candidates for lay adjudication; and (3) selection and empanelment of jurors and lay assessors for a particular case, in various post-Soviet countries and Western countries. Two key issues are examined. The article examines whether the legislation of post-Soviet countries in relation to the qualification, listing and empanelling of jurors and lay assessors is consistent with the standards applied in developed democracies. Simultaneously, the article explores what standards and rules of selection of lay adjudicators should be incorporated into the legislation of post-Soviet states in order to insure impartiality and independence of lay adjudicators. The article reveals a significant number of defects and gaps that allow executives and court personnel to manipulate the selection process and hamper the formation of impartial, independent and representative lay courts. An examination of the legislation in post-Soviet countries and of the empirical data collected in Russia lead to the conclusion that the mechanisms of the voir dire, peremptory challenges and challenges to entire juries should be reviewed and improved in order to provide reliable safeguards for the selection of impartial and independent lay adjudicators and prevent parties from excluding prospective lay adjudicators for discriminatory reasons.Данная статья сравнивает квалификации присяжных заседателей, а так же экспертов-непрофессионалов; методы выбора кандидатов для непрофессионального судебного рассмотрения; и выбор и внесение в список присяжных заседателей экспертов-непрофессионалов для конкретных случаев в различных странах постсоветского режима и в западных странах. Исследованы два ключевых вопроса. Первый: совместимо ли со стандартами, применяемыми в развитых демократических государствах, законодательство постсоветских стран в отношении квалификации, выбора и внесения в список присяжных заседателей экспертов-непрофессионалов. Одновременно, статья исследует, какие стандарты и правила выбора непрофессиональных присяжных заседателей должны быть включены в законодательство постсоветских государств чтобы гарантировать беспристрастность и независимость непрофессиональных участников процесса. Статья показывает значительное количество дефектов и промежутков, которые позволяют руководителям и персоналу суда управлять процессом отбора и препятствовать формированию беспристрастной, независимой и представительной коллегии присяжных. Экспертиза законодательства в постсоветских странах, а так же эмпирических данных, собранных в России, приводят к заключению о том, что механизмы предварительной проверки компетентности и допустимости присяжного заседателя, отвода без указания причины и вызова всех присяжных должны быть рассмотрены и улучшены для того, чтобы обеспечить надежные гарантии для выбора беспристрастных и независимых судей-непрофессионалов и препятствовать тому, чтобы стороны исключили подходящего судью-непрофессионала по дискриминационным причинам
