Постановка задачи. Одной из актуальных научно-технических задач в строительстве является совершенствование методов мониторинга состояния строительных конструкций (в том числе в стесненных условиях работы) при строительстве уникальных сооружений и объектов незавершенного строительства, обеспечивающих надежный контроль их качества, устойчивости и безопасности. Довольно часто возникают условиях, при которых нет возможности выполнить полноценный мониторинг отдельных видов деформаций строительных конструкций традиционными методами. Требуется разработка универсальных, надежных и удобных методов контроля различных геометрических параметров сооружения с целью своевременного принятия мер по обеспечению стабильности и устойчивости сооружения, чтобы исключить переход сооружения в ограниченно работоспособное или в аварийное состояние. Результаты и выводы. Предложенные в работе методы определения деформаций и качества изготовления строительных конструкций с использованием метрической фотосъемки позволяют провести полноценный мониторинг их технического состояния с необходимой точностью. Все перечисленные в статье способы контроля отрабатывались и проверялись на зданиях и сооружениях законсервированной Воронежской атомной станции теплоснабжения. Statement of the problem. One of the urgent scientific and technical problems facing construction is the improvement of methods for monitoring the state of building structures (including under confined working conditions) during the construction of unique structures and objects of unfinished construction, ensuring reliable control of their quality, stability and safety. Oftentimes, conditions arise where it is impossible to perform a full types of deformations of building structures using traditional methods. It is required to develop universal, reliable and convenient methods for controlling various geometric parameters of the structure in order to take timely measures to ensure the stability and stability of the structure in order to exclude the transition of the structure to a partially operable or emergency state. Results and conclusions. The suggested methods for determining deformations and the quality of manufacturing of building structures using metric photography make it possible to conduct a full-fledged monitoring of their technical condition with the required accuracy. All the control methods listed in the article were developed and tested on the buildings and structures of the mothballed Voronezh nuclear heat supply station.

Gotu Kola (Centella asiatica (L.) Urb) is a plant widely grown and scientifically proven to be an antioxidant. This study makes a lotion formula containing dried Gotu kola herb with varying concentrations of emulgator span 60 and tween 60. It determines the concentration of span 60 and tween 60, producing lotions with the most stable physical quality and accelerated storage methods. The lotion was prepared using a concentration of Centellaasiatica (L.) Herbaceous Dry Herb extract of 1% and an Emulgator span 60 and tween 60 in a concentration variation of 5%, 7.5%, and 10%. The stability of the lotion was determined based on quality observations. The physical condition before and after the storage is accelerated for six cycles at a temperature of 5oC and 35oC in organoleptic, homogeneous, pH, viscosity, diffusion power, and emulsion type. The research results show the physical quality stability of formula I (5% emulgator) did not meet the requirements of the dispersion test before storage was accelerated. In contrast, the formula with a 7.5% emulgator met the physical quality requirements of the preparation before and after storage was accelerated. Additionally, the 10% emulgator did not meet the requirements of the dispersion test after accelerated storage. The type of emulsion in all three formulas is the M / A type. The most stable physical quality of the three preparations is a formula with a 7.5% emulgator.Keywords: Lotion, Gotu kola (Centella asiatica (L.)

The criteria of the coordinate measurements quality at pilot-experimental production based on contemporary methods of quality management system and traditional methods of the measurements quality in Metrology are considered. As an additional criterion for quality of measurements, their duration is proposed. Analyzing the problem of assessing the quality of measurements, the authors pay particular attention to the role of technological heredity in the analysis of the sources of uncertainty of coordinate measurements, including not only the process of manufacturing the part, but all stages of the development of design and technological documentation. Along with such criteria as the degree of confidence in the results of measurements; the accuracy, convergence, reproducibility and speed of the results must take into account the correctness of technical specification, and such characteristics of the shape of the geometric elements to be controlled, such as flatness, roundness, cylindrical. It is noted that one of the main methods to reduce the uncertainty of coordinate measurements is to reduce the uncertainty in the initial data and measurement conditions, as well as to increase the stability of the tasks due to the reasonable choice of the basic geometric elements (measuring bases) of the part. A prerequisite for obtaining reliable quality indicators is a quantitative assessment of the conditions and organization of the measurement process. To plan and normalize the time of measurements, the authors propose to use analytical formulas, on the basis of which it is possible to perform quantitative analysis and optimization of quality indicators, including the speed of measurements.
