Drinking adequate amounts of fluids is important for maintaining normal bodily functions. When body water losses exceed fluid intake, dehydration may result, which can lead to numerous consequences such as headaches, dizziness, decreased mental focus, and fatigue. An athlete, who has high physical demands, may experience these negative consequences as well as muscle cramps, increased strain on the heart, and decreased athletic performance. Some beverages can replenish lost fluids better than others, due to their electrolyte (i.e. sodium, potassium, magnesium) content. This may include whey-permeate based beverages. In order to prevent dehydration, it is important to monitor fluid consumption and fluid losses. A beverage intake questionnaire (BEVQ-15) can be used to quickly assess usual beverage intake. Studies have shown that this questionnaire is accurate in children, adolescents, and adults. However, there are currently no validated methods for usual habitual beverage intake in athletes. This dissertation evaluated the taste of a new whey-permeate hydration beverage, and the accuracy and test-retest reliability of the BEVQ-15 within NCAA Division 1 collegiate athletes and found positive results. Measurements in urine and blood can be also be used to assess hydration status, but some of these methods are more expensive and less practical for daily use in real-world settings. Urine color (UC) has been studied as a hydration indicator, but this dissertation is the first to evaluate the accuracy and reliability of this method within a diverse group of collegiate athletes, in a real-world setting. Our results suggest that UC is a simple and reasonably accurate hydration assessment method when compared to another urinary assessment method. Nonetheless, there is limited research which has studied this topic. Future work can address methods to improve the effectiveness of these approaches for maintaining and evaluating fluid intake and status in the collegiate athletic population.

Full textAbstract : The speed with which the world operates today has direct repercussions on everything around us and, in the foreground, on the construction market, where the criteria are more and more demanding such as short construction times, complexity of forms, etc. The use of fluid concretes where rheological properties are well controlled is a key to satisfy these criteria, especially since we are on the threshold of a new era in the construction world including the 3D concrete printing. However, an adequate selection of mineral additives (MA) and chemical admixtures (superplasticizers, SP and viscosity agents, VA) that are used in the design of fluid concretes is a crucial problem. A very extensive experimental program is conducted to shed light on the effect of eight different MA in binary and ternary systems as well as the effect of their interactions with the chemical admixtures (SP and VA) on the properties of concrete equivalent mortars (CEM). Two classes of fluid concretes are investigated in this study, including self-consolidating concrete (SCC) for building constructions and semi-flowable concrete (SFC) for transportation infrastructures. Particular attention is paid to the rheological properties, without neglecting the heat of hydration as well as the mechanical properties. The results showed that it is difficult to generalize on the influence of MA on the properties of CEM. The physical properties of MAs such as fineness, shape or particle size distribution are factors that play an important role in the rheology of fluid concretes. However, the influence of these factors can be masked by the physical and chemical interaction that may occur between the powders and the chemical admixtures used (type of SP in the presence or not of a compatible VA). The particle morphology of MA has a direct effect on the plastic viscosity of CEM. An angular and irregular shape (Ferret factor around 0.4) contributes to increase the plastic viscosity of CEM and a spherical shape (Ferret factor close to 1) contributes to decrease their plastic viscosity. Moreover, the results of the statistical analysis showed that the influence of MA in ternary combination (low-reactivity powder with high-reactivity powder), in the presence of a relatively high water-to-powder ratio (W/P) of 0.45, on the majority of responses is only the sum of the individual effects of these powders. On the other hand, an interaction effect between the powders for some responses began slightly when the W/P was decreased to 0.41. However, in developing 28- and 91-day compressive strengths, high-reactivity powders such as silica fume or metakaolin generally had positive contribution higher than low-reactivity powders. Results of ternary CEM hydration followed by isothermal calorimetry did not show the expected synergistic effect of combining a low-reactivity powder with another with high reactivity due to increased demand in SP in the presence of the latter. A multiparametric optimization allowed selection of ternary cements used to develop ecological concretes with the best performance. Finally, the use of the CEM method in prediction of the effect of AM on concrete was discussed.

Full textНа основании анализа теоретических, экспериментальных и практических работ выделено основные причины возникновения миграции пластовых флюидов на начальном этапе формирования тампонажного камня главными этих причин следует считать появление движущей силы, которая возникает при уменьшении гидростатического давления столба там понажного расствора и образовании суффозионных каналов миграции пластовых флюидов. При исследовании характера и условий передачи гидростатического давления через столб тампонажного раствора в процессе его твердения установлено, что причиной передачи давления является фильтрация флюида через пористую среду с продуктов гидратации цемента, а её прекращение связано с процессами зарастания поровых каналов. Показано, что существующая на сегодняшний день рекомендация, согласно которой конец схватывания в нижней порция тампонажного раствора должен наступать не позднее двух часов до начала схватывания верхней порции, справедлива только для портландцементных растворов. Для специальных цементов и тампонажных растворов с добавкой замедлителя сроков схватывания эта рекомендация неприемлема. Установлено наличие связи между величиной передаваемого давления и прочностью камня на сжати е независимо от типа вяжущего, наличия и вида добавок регуляторов срока схватывания тампонажного раствора и других факторов. Устанавлены критические значения границ прочности камня на сжатие, при которых начинается снижение коэфициента передачи и полностью прекращается передача давления, которые соответственно составляют 0,56 i 1,42 МПа. Тампонажные растворы, граница прочности камня которых на сжатие не превышает 1,42 МПа, не обеспечивают герметичности цементного камня, а их использование может стать причиной возн икновения заколоннс й миграции пластових флюидов. Усовершенствована технология разобщения продуктивных горизонтов, которая заключается в цементирование двумя порциями тампонажних растворов с разными темпами набора прочности камня. Нижняя порция (для интервала залягания продуктивного горизонта) должна достигать прочности,42 МПа, до того, как прочность верхней порции достигнет 0,56 МПа. Разработано методику подбора рецептур тампонажного раствора для конкретных горно-геологических условий ДДв. Предложено для снижения проницаемости цементного камня на начальных стадиях твердения связывать избыток воды затворения и придавать ей начальное напряжение сдвига кремнийорганическими соединениями типа АКОР. На основе теоретических и экспериментальных работ разработана методика и определены оптимальные концентрации АКОРбзоо» составляющие в зависимости от водоцементного соотношения Зн-6% массы вяжучего. Пористость цементного камня на начальной стадии твердения не зависит от типа вяжущего, водоцементного отношения и введённых химреагентов, а определяется только степенью его гидратации. Исследованы технологические свойства рецептур тампонажных растворов и полученного цементного камня з добавками АКОР. Добавка АКОРбзоо в состав тампонажного раствора улучшает его реологические параметры, повышает седиментационную устойчивость, понижает фильтрацию и не изменяет при этом сроков схватывания. АКОРбзоо существенно снижает проницаемость камня на начальной стадии твердения без ухудшения его прочностных характеристик. Экспериментальными исследованиями величины расширения при твердении цементно-зольных смесей с добавками АКОРвзоо установлено, что они являются безусадочными. Изучением влияния добавки АКОРбзоо на кинетику объемных изменений расширяющихся тампонажных растворов установлено, что она не уменьшает величины расширения. Коррозионная устойчивость цементно-зольных смесей с добавкой АКОРвзоо в агресивных солях сульфата и хлорида магния повышается. По результатам експерименгальных исследований показана целесообразность использования добавки АКОРбзоо при пластовых температурах 100-тТ30°С. Результаты проведённых научных исследований вошли в состав проектов руководящих нормативных документов по креплению скважин для буровых организаций Департамента геологии и использования недр, и ДК ’’Укргаздобыча”.

The given thesis contains the study of the nature: and conditions for pressure transmission through the column of g routing mortar in the process of its setting. There has been fixed the relation between the value of the pressur transmitted and the rock compressive strength. Also there ha ve been defined the critical values of compression strength of cement rock, at which pressure transmission starts lowering and stops. Cementing tehnology has been improved, and methods of selecting formulae to prevent gas, oil and water manifestations at the initial stage of grouting mortar settihg have been developed. To lower the perméabilité of cement rock at the initial stage of setting, it has been suggested to add mixing water excesses and to dring them to the initial stress level of the displacement by AKOP - silicon organic compouds belonging to silanes. There have been described the positive properties of grouting mortars and of formed rock wint AKOP admixtures. The results of the inverstigation can be found in the nonnative documents on well grouting, sent winh the aim of implementation to the drilling enterprises that belong to the Departament of geology and mineral and natural resources use in Ukraine, and to ’’Ukrgazvydobuvannia” branch company. The recommendations at cementing tehnology are introduced in drilling Companys.
