Thermoregulatory System

In the constantly changing conditions of the external environment, the microclimate is supported by the stabilizing systems of the building in the overall system ”building - exterior fences and engineering equipment”. To create a comfortable microclimate in the room, special systems are used: heating, ventilation, and humidification. To create thermal comfort indoors means ensuring its complex meteorological conditions in which the thermoregulatory system of the body is in a state of the least tension, and all the other physiological functions occur at the level most beneficial for the body. In the modern world the quality of the indoor environment is a priority, part of the requirements is reflected in the modern standards of green building, part in the national standards. So the Russian Federation has legislative and normative-legal acts, reflecting the characteristics of environmental quality: GOST (State Standard) 30494-2011, SanPiN (Sanitary Regulations and Norms) 2.1.2.1002-00, GOST R ISO (Russian National Standard) 7730-2009, SN 2605-82, SNiP (Construction Standards and Regulations) 23-05-95 and others. Normalized microclimatic indicators include temperature, humidity and air velocity, surface temperature of building envelopes, objects, equipment. But at the present stage, the formation of a harmonized and safe environment of the room depends on many factors, which should not only reflect functional, social, climatic, urban planning, construction design, architectural-artistic and economic characteristics, but also socio-psychological and environmental components of the room.

Standard Development

Основными средствами локализации нефтяных разливов в акваториях являются боновые заграждения. Несмотря на их повсеместное использование, в течение долгого времени отсутствовал национальный стандарт, регламентирующий требования к данному виду оборудования. Соответствующий стандарт - ГОСТ Р 58190-2018 - был введен в действие 1 апреля 2019 года. Основой для его создания стал нормативный документ ПАО «Транснефть», доработанный с учетом анализа зарубежного опыта нормирования требований к боновым заграждениям, опыта эксплуатации бонов морских тяжелых, состояния рынка данного вида оборудования, используемых материалов и технологий производства. ГОСТ Р 58190-2018 впервые определил боны морские тяжелые как отдельный класс боновых заграждений, установил и закрепил на национальном уровне требования к ним, что надо расценивать как важный шаг в обеспечении качества данного вида оборудования. В настоящей статье авторы, принимавшие участие в разработке стандарта, представляют анализ итогов разработки и рассматривают возникшие в связи с этим проблемные вопросы. Сформулированы рекомендации с целью повышения качества деятельности в области технического регулирования. Сделан вывод о целесообразности рассмотрения вопроса о создании в перспективе национального стандарта, определяющего основные типы боновых заграждений, требования к ним, рекомендации по применению. Опыт разработки ГОСТ Р 58190-2018 может быть распространен на другие виды оборудования и использован при разработке других национальных стандартов. The basic means for the containment of oil spills in water areas are booms. Despite its common usage, for a long period of time there were no national standard regulating the requirements to this kind of equipment. Such standard, GOST R 58190-2018, became effective on April 1, 2019. The basis for its establishment was Transneft PJSC reference document, which was revised with regard to the analysis of foreign experience in standardizing the requirements for booms, experience in operating heavyweight marine booms, the state of the market for such equipment, materials and production technologies used. GOST R 58190-2018 for the first time determined heavyweight marine booms as a separate group of defense booms, established and consolidated the requirements for such equipment effective on the national level. Within the present article the authors, who took part in the standard development, set forth the analysis of the development results and consider problems related to this issue. The authors present recommendations with the purpose of increasing the quality of measures taken in the field of technical regulation. The conclusion is made whether it is practical to consider the question of creating national standard, which defines basic types of defense booms in general, the requirements and application recommendations. The experience of developing GOST R 58190-2018 can also be applied to other types of equipment and used for the development of other national standards.

Milk and dairy products play an important role in the human diet and society's health. The aim of this study was the assessment of the microbial quality of industrial and traditional breakfast cream in Alborz province, Iran. In this study, 40 different samples of breakfast cream (20 samples of traditional breakfast cream and 20 samples of industrial pasteurized breakfast cream) were collected randomly in Alborz province in 2018. Microbial quality tests were performed according to Iran National Standards on Coliforms, Escherichia coli, and Staphylococcus aureus, and then the collected data were analyzed. The microbiological examinations revealed that 43% of the samples were contaminated with coliform bacteria that 12 samples (60%) out of 20 samples of traditional cream, 5 samples (25%) out of 20 samples of industrial cream were higher than the allowable microbial limit of the national standard of Iran. About 15% of samples of traditional creams and 10% of industrial creams were contaminated with Escherichia coli. 10% of samples of traditional cream were contaminated with Staphylococcus aureus, which was not observed in industrial creams. High contamination with bacteria, needs using different methods to control microbial growth, including the promotion of sanitary awareness among laborers, the codification of microbial standards for traditional dairy products, training to staff for preparing the cream and disinfection of tools.

Abstract The importance of water in everyday life is clear for humans and living creatures. In addition to supplying the water required for the body, it also contains necessary minerals. An increase or decrease in these minerals is responsible for various diseases and problems. Due to the growing consumption of treated water in Birjand, Iran and the need for the continuous monitoring of the quality of treated water, this descriptive research aimed to determine the chemical and microbiological quality of treated water of desalination stations in Birjand from September 23rd, 2015 to March 19th, 2016 (autumn and winter). Samples were directly taken from the desalination stations of Birjand. Physical and chemical tests were performed according to the Standard Methods. The results were compared with national standards as well as World Health Organization (WHO) guidelines. The results showed that almost all measured chemical and bacterial characteristics were less than the national and international standards. Also, the samples were standard in terms of coliforms and fecal coliforms. In some stations the concentrations of free residual chlorine and also magnesium were higher than standards. Therefore, periodic investigation of quality parameters is recommended in all desalination stations to reflect the results to authorities.

Cheese and yogurt are two kinds of nutritious dairy products that are used worldwide. The major preservatives in dairy products are sodium benzoate, potassium sorbate, and natamycin. The maximum permitted levels for these additives in cheese and yogurt are established according to Iranian national standards. In this study, we developed a method to detect these preservatives in dairy products by reversed phase chromatography with UV detection in 220 nm, simultaneously. This method was performed on C18 column with ammonium acetate buffer (pH=5) and acetonitrile (73 : 27 v/v) as mobile phase. The method was carried out on 195 samples in 5 kinds of commercial cheeses and yogurts. The results demonstrated insufficient separation where limit of detection (LOD) and limit of quantitation (LOQ) ranged from 0.326 to 0.520 mg/kg and 0.989 to 1.575 mg/kg in benzoate and sorbate, respectively. The correlation coefficient of each calibration curve was mostly higher than 0.997. All samples contained sodium benzoate in various ranges. Natamycin and sorbate were detected in a remarkable amount of samples, while, according to Iranian national standard, only sorbate is permitted to be added in processed cheeses as a preservative. In order to control the quality of dairy products, determination of preservatives is necessary.

The quality of education is still a benchmark of human resources (HR) in each country. The current era of revolution 4.0 requires a curriculum that is innovative, creative, and based on the needs of market share and the world of work with the addition of several new literacies. This study aims to identify and evaluate the tertiary curriculum (higher education curriculum) that has been applied in a higher education institution of health sciences in Buleleng, which refers to the national standard of higher education no. 44 of 2015. The evaluation was based on input, process, and output. The method used was the mixed method by using questionnaires and focus group discussions on 32 lecturers from the three knowledge fields of midwifery, nursing, and pharmacy. The results show that of the four standards evaluated, the learning process standard and assessment standard need to get priority in improving the academic system at the institution. Both of these components must be immediately improved in terms of concepts and understanding so that the goals, achievements, and quality of graduates can still be improved and maintained. Internal discussions and workshops should be done regularly each semester to refresh pedagogical ability and understanding of the regulatory faculty curriculum.

Explosive Devices

Portable X-ray imaging systems are routinely used by bomb squads throughout the world to image the contents of suspicious packages and explosive devices. The images are used by bomb technicians to determine whether or not packages contain explosive devices or device components. In events of positive detection, the images are also used to understand device design and to devise countermeasures. The quality of the images is considered to be of primary importance by users and manufacturers of these systems, since it affects the ability of the users to analyze the images and to detect potential threats. As such, there exist national standards that set minimum acceptable image-quality levels for the performance of these imaging systems. An implicit assumption is that better image quality leads to better user identification of components in explosive devices and, therefore, better informed plans to render them safe. However, there is no previously published experimental work investigating this. Toward advancing progress in this direction, the authors developed the new NIST-LIVE X-ray improvised explosive device (IED) image-quality database. The database consists of: a set of pristine X-ray images of IEDs and benign objects; a larger set of distorted images of varying quality of the same objects; ground-truth IED component labels for all images; and human task-performance results locating and identifying the IED components. More than 40 trained U.S. bomb technicians were recruited to generate the human task-performance data. They use the database to show that identification probabilities for IED components are strongly correlated with image quality. They also show how the results relate to the image-quality metrics described in the current U.S. national standard for these systems, and how their results can be used to inform the development of baseline performance requirements. They expect these results to directly affect future revisions of the standard.
