Construction training process of highly skilled players in mini-football for competition period

Analyzed the structure and content of the competition period in mini-football. It was determined that the structure of the competition period consists of 4 competitive mesocycles. In each mesocycle includes various types of micro-cycles (competitive, cross-game and rehabilitation). Reflects the ratio of specific and non-specific (general preparations) means training work. So in the competitive period for competitive mesocycles general preparations exercises ranged from 38.3 to 42.4%, special-preparation - from 29.9 to 32.6%, competitive - from 20.9 to 23.3%. The intensity of the training load in intergame microcycles less than competitive. This corresponds to the strategy of building the training process in the competitive period. During the competition period the ratio of the training load was: aerobic focus - 49.2%, mixed - 46.1%, anaerobic alactate - 2.4%, anaerobic glycolytic - 2.3%. Defines the scope and focus of the training load: longer the aerobic work, then - mixed, anaerobic- alactate and anaerobic-glycolytic. The comparative characteristics of the intensity of the training load in competitive and intergame microcycles

Performance of Tack Coat Materials in Saskatchewan Climate

Tack coat materials are used to provide sufficient bond between an existing asphalt concrete layer and a new asphalt concrete overlay or between two lifts of a new asphalt concrete layer. Tack coat materials are typically emulsified bituminous materials. Tack coat performance has not been extensively studied in the harsh climate of Saskatchewan. In practice, tack coat materials are often picked up on the tires of paving equipment, which leaves little tack coat material in the wheel paths where it is needed most. An ideal tack coat material should have a short curing time and a high bond strength to achieve better constructability and performance of the pavement structures. Improper installation of the tack coat material can lead to a poor bond and premature failure of the pavement structures. The objective of this research is to evaluate the strength and performance of several tack coat materials in Saskatchewan climate. Findings from this research will be used by the Saskatchewan Ministry of Highways and Infrastructure to create a recommended tack coat material list and provide guidelines for construction best practices. Currently, most tack coat materials selected for road construction in Saskatchewan are the basic slow-setting emulsion, SS-1. The tack coat materials tested in this research include basic anionic emulsions: SS-1, SS-1h, MS-1, a cationic emulsion: CSS-1h, and three proprietary quick setting/non-tracking emulsions provided by industry partners. Tack coat performance was evaluated through a field study as well as a laboratory-testing program. Ten test sections were constructed in August 2017 on a two-way, two-lane rural highway near Blaine Lake, Saskatchewan. At the time of test section construction, weather conditions, tack coat material curing properties, and application rate were measured. The proprietary products had faster setting and breaking times as well as less pickup of tack coat onto vehicle tires than all other products. All tested products had better setting and breaking times than SS-1. A correlation between tack coat breaking and setting times with temperature and humidity at the time of construction was observed. Two distress surveys were conducted post-construction in September 2017 and after one year in September 2018. The two distress surveys did not show early distresses or deformities in the road due to poor bonding between pavement layers. Laboratory testing was conducted on the cores collected from the test sections to evaluate the interlayer shear strength using a Louisiana Interlayer Shear Strength Tester according to AASHTO TP 114. Cores collected after construction were separated into two groups: baseline cores and freeze-thaw conditioned cores. Baseline cores were tested to measure initial bond strength after construction. Conditioned cores were exposed to three levels of freeze-thaw cycling: 3, 9, and 15 freeze-thaw cycles. Each freeze-thaw cycle consisted of twelve hours of freezing at -25°C and twelve hours of thawing at 15°C. The baseline cores, one year cores, and laboratory conditioned cores were tested to evaluate the change in bond strength over time. The laboratory-performance of tack coat materials was quantified based on interlayer shear strength (ISS), strain, k modulus, energy to peak stress, and the type of failure of core samples. Samples collected after one year showed higher ISS than baseline cores. Lab conditioned cores had higher ISS than baseline cores but lower ISS than year one cores. The increase in bond strength after one year and lab conditioning can be attributed to the continuous curing of tack coat materials. The failure type of bond strength samples was classified into two types according to shape and location of the failure surface: Type A (clean failure at the tack coat surface) and Type B (failure partly in the mix). Failure Type B indicates that the tack coat material can successfully provide enough bond strength to make the two asphalt concrete lifts behave as one thick homogenous layer. Although TackMaxTM and Colasphalt Tack had lower ISS values than SS-1 NB (50-50W) and SS-1 (30-70W), TackMaxTM and Colasphalt Tack showed stronger type of failure (Type B). Therefore, failure mode should be considered when evaluating bond strength of cores in addition to ISS value. The energy required to reach the peak shear stress is a comprehensive parameter that accounts for both the applied stress and the amount of deformation that the sample undergoes before reaching bond failure. Results show that the ranking of tack coat materials varies if the energy values are used as the ranking criterion instead of ISS values. Therefore, the energy required to reach peak shear stress is a significant parameter that should also be considered when evaluating tack coat materials. Overall, SS-1h, MS-1, CSS-1h, and the 3 proprietary products showed better performance than SS-1 emulsion according to the test results of the baseline and year one cores

Економічна культура як фактор інноваційного розвитку економіки країни

Проблеми взаємовпливу та взаємозв'язку економіки і культури складні й різноманітні, тому є теоретично й практично актуальними: без глибокого вивчення і методологічного та інституціонального визначення їх ролі неможливо зрозуміти сутність сучасних тенденцій в глобалізованому економічному процесі і нові тенденції суспільного середовища. В сучасному розумінні роль культури в економічному аспекті слід розглядати як функціонально пов’язану з усім суспільним виробництвом, головним чином – у відтворенні робочої сили та «інтелектуальному оснащенні» працівника. Сьогодні інновації та знання пронизують не тільки всі сфери певної національної економіки, вони «розсіюються» у світовому просторі, перетинаючи державні кордони. У цьому випадку мова йде про міжнародний перелив або трансфер знань, який формується під впливом економічної культури суспільства

Microscopic Studies of Sedimentary Organic Matter: Key to Understanding Organic-Rich Strata, with Paleozoic Examples from Western Canada Basin

Organic matter in sediments and sedimentary rocks provides data and interpretations on biosphere-geosphere interactions. In modern and ancient depositional settings, a combination of anoxia and substantial bio-productivity leads to the preservation of abundant organic matter, which in turn is transformed during subsequent burial into kerogen, the source of oil and gas deposits. Kerogen can be evaluated by organic geochemistry and organic penological methods, whose parameters are used to define organic fades for fine-grained, sedimentary rock sequences. Organic geochemistry uses Rock-Eval pyrolysis and elemental analysis to determine amounts of organic C, H, and Ï in kerogen to assess petroleum potential and origin. Organic petrology uses reflected light microscopy to characterize dispersed organic matter in rocks, in terms of macerals and organic facies, which is then used to interpret the paleoenvironment and paleoecology of organic-rich sedimentary rocks. This paper outlines the organic petrology of several hydrocarbon source rocks from western Canada, illustrating the success of this method in evaluating and understanding organic-rich rocks. Résumé La matière organique dans les sédiments et les roches sédimentaires fournit des données et des informations sur les interactions entre la géosphère et la biosphère. Dans les bassins sédimentaires actuels ou anciens, la présence de conditions anoxiques en même temps qu'une forte bio-productivité conduit à la conservation de grands volumes de matière organique, lesquels se transforment par la suite en kérogène, la source des gisements de pétrole et de gaz. On utilise des méthodes de géochimie et de pétrologie organique pour étudier le kérogène et les données qu'elles fournissent permettent de définir les faciès des séquences de roches sédimentaires à grains fins. En géochimie organique, la pyrolyse Rock-Éval et l'analyse élémentaire permettent de déterminer les quantités de C, H et O organiques du kérogène et d'évaluer le potentiel pétrolier ainsi que l'origine. En pétrologie organique la microscopie en lumière réfléchie permet de caractériser la matière organique dispersée dans les roches. Ensuite, des macéraux et faciès organiques décrits on peut déduire les paramètres paléo-environnementaux et paléo-écologiques des roches sédimentaires riches en matière organique. On trouvera dans le présent article des descriptions abrégées de la pétrologie organique de plusieurs roches mères de l'Ouest canadien et qui illustrent bien l'efficacité de cette méthode dans l'évaluation et la compréhension des roches riches en matière organiques

An Enumeration Problem for Sequences of n-ary Trees Arising from Algebraic Operads

This thesis solves an enumeration problem for sequences of complete n-ary trees. Given the sequence of all complete n-ary plane trees with a given number of internal nodes (weight), in lexicographical order, we perform graftings with the basic n-ary tree to construct sets of sequences of trees of higher weight. Determining the number of elements of these sets solves a problem originating from the theory of free nonsymmetric operads, as the sets of sequences of trees are equivalent to spanning sets of homogeneous subspaces of a principal operad ideal. Two different solutions will be presented: one using recurrence relations and properties of forests, the other using occupancy problems

Towards understanding the design of dual-modal MR/fluorescent probes to sense zinc ions

A series of gadolinium complexes were synthesised in order to test the design of dual-modal probes that display a change in fluorescence or relaxivity response upon binding of zinc. A dansyl-DO3ATA gadolinium complex [GdL1] displayed an increase and a slight blue-shift in fluorescence in the presence of zinc; however, a decrease in relaxation rate was observed. Consequently, the ability of the well-known zinc chelator, BPEN, was assessed for relaxivity response when conjugated to the gadolinium chelate. The success of this probe [GdL2], lead to the inclusion of the same zinc-probing moiety alongside a longer wavelength emitting fluorophore, rhodamine [GdL3], to arrive at the final iteration of these first generation dual-modal zinc-sensing probes. The compounds give insight into the design protocols required for the successful imaging of zinc ions
