Using Innovative Tools and Lean Writing Workflow Processes to Accelerate Regulatory Document Writing

Lean writing workflow processes can streamline development of complex documents, including protocols and other regulatory submissions. This paper outlines standard development timelines and describes useful lean writing workflow methods and tools to reduce protocol development timelines without sacrificing document quality. We present the results of a survey completed by 75 Medical writers (MW) that reveal the strategies used during document preparation and use real case scenarios (protocol development) that illustrate how innovative tools and approaches can be efficiently used to create a lean writing workflow process. Software tools (e.g., proofreading assistance, citation manager, collaborative authoring and reviewing) were widely accepted and used during protocol development according to the MWs surveyed. Most of the surveyed writers (62%) hypothesized a reduction in production time by about 25%. Efficient collaborative work across different time zones had a marked impact on shortening timelines while maintaining production of high-quality documents. Real case scenarios were used to illustrate how innovative tools and approaches can positively impact timelines and efficiently create a lean writing workflow process regardless of therapeutic area. The real case scenarios showed that protocol development time can be decreased by about 26% without compromising the quality of the document. This shows that software tools, templates, checklists, and collaborative writing were more impactful than hypothesized by the MWs included in the survey. With clear workflow processes, roles, and responsibilities backed by innovative software applications, template guidelines, and collaborative work processes, MWs can overcome common development challenges and improve their lean regulatory writing skills.

Scabies in dermatovenerologist practice: a clinical case of delayed diagnosis in a patient with chronic dermatosis. Case report

Despite the current approaches to diagnostics and treatment, regulatory documentation and guidelines, the diagnosis of scabies can often be delayed. The long-term scabies can mimic acute and chronic dermatoses which causes inadequate treatment. Physicians, including dermatovenerologists, misdiagnose scabies. Aim – to clarify historical aspects of scabies, present a clinical case of scabies complicated by allergic dermatitis and lymphoplasia in a patient with Darye's disease as an example of delayed diagnosis of scabies, errors in management tactics and features of treatment of scabies in a patient with chronic dermatosis.

OPTIMIZATION OF THE METHOD OF QUANTITATIVE DEFINITIONS OF FLAVONOIDS IN THE RAW MATERIALS OF "MENYANTHIDIS TRIFOLIATAE LEAVES"

The aim of the study is to optimize the methodology of quantitative determination of flavonoids in the leaves of Menyanthidis trifoliatae. In official medicine, the leaves of Menyanthidis trifoliatae are used for anorexia and dyspeptic disorders.
 In the current regulatory documentation (State Pharmacopoeia of the Russian Federation), it is proposed to evaluate the quality of raw materials by the content of the amount of flavonoids in terms of rutin using spectrophotometry. This technique is based on the ability of flavonoids containing free aromatic hydroxyl groups to form colored products with diazotized sulfanilic acid. The disadvantage of this technique is the long and time-consuming stage of cleaning raw materials from certain groups of lipophilic substances, which can also react with diazotized sulfanilic acid to form colored products.
 We have proposed a selective method for the quantitative determination of flavonoids in the herb trifoliate by the method of spectrophotometry in terms of rutin. The technique is based on the ability of flavonoids to form stable colored complexes with aluminum chloride. We have selected the optimal conditions for extraction and complexation reaction of aluminum chloride with flavonoids of M. trifoliatae extract. The proposed method has been validated and is suitable for use in an analytical laboratory.

ВОЗМОЖНОСТЬ ИСПОЛЬЗОВАНИЯ ПОРТУЛАКА ОГОРОДНОГО (PORTULACA OLERACEA L.) ДЛЯ ОБОГАЩЕНИЯ МЯСНЫХ РУБЛЕНЫХ ИЗДЕЛИЙ

The purpose of the study is to identify the possibility of using the aerial part of purslane in cutlet recipes. Objectives: to determine the dosage of purslane in ground turkey meat, ensuring the best quality indicators of the product; to conduct a tasting assessment of the product; to develop a schematic diagram for the production of semi-finished meat and vegetable products. The components for the production of chopped semi-finished meat products complied with the regulatory documentation: turkey meat – in accordance with GOST R 55365-2012 “Mince meat. Technical conditions" and GOST 32951-2014 "Semi-finished meat and meat-containing products. General technical conditions"; chicken eggs – according to GOST 31654-2012 “Chicken eggs for food. Technical conditions"; onions – according to GOST 34306-2017 “Fresh onions. Technical conditions"; black pepper – according to GOST 29050-91 “Spices. Black and white pepper. Technical conditions"; table salt – according to GOST R 51574-2018; vegetable oil – according to GOST 1129-2013; breadcrumbs – according to GOST 28402-89. Organoleptic and tasting assessment of finished products was carried out in accordance with GOST 31986-2012 (GOST 7269-2015 and GOST 9959-2015) on a 5-point scale. A recipe was developed for turkey meat cutlets with the addition of a plant component – purslane. Purslane was collected in the vicinity of Krasnoyarsk and was added crushed to minced meat in dosages from 3 to 9 % in increments of 3 instead of raw meat. The study of the organoleptic characteristics of the finished minced meat product showed that the rational dosage introduced into the meat cutlet mass of the vegetable ingredient is 6 % of the mass of the minced meat. The test sample with the introduction of 6 % plant component received the highest rating from tasters. Stages for the production of cutlets have been developed with the addition of chopped aerial parts of purslane to the recipe. The use of purslane in the recipe for chopped semi-finished meat products will help expand the range of this type of product, improve the consumer properties of meat products, increase the content of essential components in the composition, and reduce costs.

ИССЛЕДОВАНИЕ ХИМИЧЕСКОГО СОСТАВА НЕКОТОРЫХ ПРЕДСТАВИТЕЛЕЙ РОДА TANACETUM L.

The purpose of the study is to study the biochemical parameters of three species of the genus Tanacetum: T. balsamita L. (balsamite), T. balsamitoides Sch.Bip. (P. balsamonosa) and T. vulgare L. (P. vulgare). For the study, we used the raw materials of tansy produced by OJSC Krasnogorskleksredstva, a wild-growing type of tansy harvested in the Ufa District of Bashkiria, and we also used the raw materials of balsam tansy and balsam-like tansy, grown in the botanical garden-institute (Ufa). For chemical analysis, plants were harvested at the beginning of flowering, cutting off shoots at a level of 10–15 cm from the ground. The raw materials were dried using the air-shade method under canopies in ventilated rooms, laid out in a thin layer and stirred periodically. The raw materials were packaged and stored in accordance with the requirements of regulatory documentation (OFS.1.1.0019.15) at room temperature in a dry room, not infested with pests, with good ventilation, without direct sunlight. Commodity analysis of raw materials was carried out by generally accepted pharmacopoeial methods according to the following indicators: moisture, total ash and ash insoluble in hydrochloric acid. Qualitative detection of biological active substances was carried out using qualitative reactions and chromatographic research methods. Quantitative determination of ascorbic acid (FS.2.5.01.06.18), tannins (OFS 1.5.3.0008.18) and organic acids (FS.38) in tansy flowers was carried out by titrimetric methods, determination of essential oil content by steam distillation (OFS.1.5.3.0010.15). The commodity indicators of the raw materials of the studied tansy samples: moisture, total ash and ash insoluble in a 10 % hydrochloric acid solution do not exceed the content standards specified in the pharmacopoeial monograph. The chemical composition of the studied tansy species contains valuable biologically active substances, among them essential oils, tannins, ascorbic acid, and organic acids, which may allow the use in scientific medicine not only of T. vulgare, but also of T species used so far only in folk medicine balsamita and T. balsamitoides, which successfully passed the introduction test at the South Ural Botanical Garden-Institute of the Federal Research Center of the Russian Academy of Sciences.

Особенности создания трансформаторов судовых систем электродвижения

The necessity of new organizational and technical solutions in shipbuilding to ensure the quality of marine transformer transformers is substantiated. The analysis of the requirements of the Russian Maritime Register of Shipping, the current ISS for dry transformers is carried out, the experience of enterprises of related industries and foreign companies, the design features of power transformers of the ship's electric propulsion system are considered. The results of the analysis of the requirements for power transformers of marine electric propulsion systems, the features of their design and operation are presented. The main parameters of the converters in operating and emergency modes are considered and analyzed. The organizational and technical directions of ensuring increased reliability of marine converter transformers are proposed. Unlike converter transformers for land transport, there are no regulatory documents for power converter transformers in shipbuilding. The regulatory documents in force in shipbuilding do not fully take into account the specifics of marine conversion transformers. The existing main features of marine converter transformers are noted. High economic losses in the event of an accident of marine converter transformers determine higher requirements for their electrodynamic stability compared with converter transformers for land transport. In shipbuilding, there are no requirements for determining the partial short-circuit voltage and the splitting short-circuit voltage during testing of transformers necessary for the analysis of their characteristics and modes. When creating marine converter transformers, it is necessary to justify the characteristic modes of marine transformers using computer modeling, develop methods for measuring and calculating the parameters of selected modes and perform process calculations for the most likely accidents in the transformer – rectifier system. With the increase in the power of shipboard electric propulsion systems, the development of state regulatory documentation to ensure the quality of development and operation of converter transformers is becoming increasingly relevant.

ASSESSMENT OF THE QUALITY OF ENRICHED YEAST-FREE BREAD FROM DIFFERENT TYPES OF FLOUR

Today, nutrition is an important factor that determines the state of human health. It is thanks to the right diet that the human body resists the harmful effects of the environment, which affects life expectancy and even the emotional state. The world is facing the issue of the relevance of producing products characterized by high nutritional value and high consumer properties. Bread is accessible to all segments of the population and is one of the most consumed products. There is a growing interest in yeast-free bread, which is widely considered to be healthier and more nutritious, usually contains more vitamins and minerals, and has a lower glycemic index, i.e. less impact on blood sugar levels, making it more beneficial for diabetics The possibility of making yeast-free bread using different types of flour: rye, whole wheat, and first-grade wheat was investigated. The organoleptic characteristics of the prepared bread products were determined. It was found that all the prepared bread samples comply with the regulatory documentation in terms of surface condition, consistency, smell, and taste. Thus, based on the results of the organoleptic tests, all types of flour used in the study can be used for the preparation of yeast-free bread. To increase the nutritional value of bread products, it is proposed to add pumpkin meal, a natural product of plant origin containing more than 50 different biologically active components: a significant amount of proteins, essential amino acids, vitamins, minerals, and dietary fiber, to the recipe of unleavened bread made from different types of flour, which can improve the quality and nutritional value of bread. It has been shown that the addition of meal in the amount of 5% provides excellent organoleptic characteristics for the resulting bread products.

On the issues of criticism and further development of the national regulatory framework for the calculation of structures for seismic impacts

A scientific analysis of the provisions of the studies [1–4] devoted to the critical analysis of the state of regulatory documentation on the calculation of structures for earthquakes has been carried out. In these works, it is argued that the developers of domestic standards made a serious methodological mistake when dynamic coefficients, rather than reaction spectra, were used when setting the initial seismic information. It is believed that in foreign norms, as well as in the monographs of famous foreign scientists, the ground parts of structures during earthquakes are not affected by any external forces. This incompleteness of representations is present in the equation of horizontal vibrations in translated and domestic works and monographs, but in them, unlike the analyzed works, it is not stated that during earthquakes the ground parts of structures are not affected by any external forces. The reasons for the inadequacy of mathematical models of the interaction of foundations and structures are revealed and the equations of translational and rocking plane-parallel vibrations of a rigid structure on a pliable base are given, clearly taking into account the effect of gravity.

RENTAL HOUSING IN MULTIFUNCTIONAL COMPLEXES. STANDARDIZATION PROPOSALS

The article considers proposals for changes to regulatory documentation in Ukraine, for the introduction of a new typological unit - rental housing. From the point of view of the historical evolution of residential construction, - replenishment of the typological series of residential buildings with the type of "rental housing", - the return of the concept of "income building", which spread in Europe from the end of the 19th century - the beginning of 20th century. An urgent problem at the moment is the shortage of housing. Including for young families. The war destroyed housing in many cities and towns of Ukraine. As a result, there was a large category of people - temporarily displaced persons. People who, unfortunately, lose their homes every day as a result of rocket and artillery shelling, urgently need to rebuild or build new houses and apartments in the safest possible places. The provision of housing is at the core of human nature as a civilized individual. Thus, according to the model of "Maslow's pyramid" - a diagram that hierarchically represents human needs - these needs are based on physiological needs, and the second place is occupied by the safety of health, property and the future of a person. The following social and psychological factors are based precisely on stability in the field of safety and physiology. Therefore, among other things, it is high-quality and safe housing that will give a person psychological confidence and will be able to influence various social factors at the national level, including the demographic situation, which suffered a very significant negative impact during the war. Providing clear regulatory limits and definitions will allow designers to be armed with clear tools to implement the new typological unit of "rental housing". Implementation of the principle of parametric normalization will allow finding innovative design solutions. Current building regulations of Ukraine do not define "Rental housing" as a separate typological unit. Similarly, in the new National Classification of Buildings and Structures NK 018:2023 [23], the type "rental housing" did not appear, although the Law of Ukraine "On Rental Housing" has currently been adopted in the first reading. The functional classification of housing for temporary residence refers to premises such as residential apartments, apart-hotels, hotel apartments and others - to buildings of public purpose. At present, only such type of individual accommodation as dormitories refers to residential buildings. Therefore, the inclusion of such types of buildings as rental residential buildings in the regulatory documentation in Ukraine is an urgent and socially significant task.

ECOLOGICAL AND HYGIENIC ASSESSMENT OF THE QUALITY OF BURDOCK ROOTS OF LARGE FLORA OF URBANIZED TERRITORIES OF THE CENTRAL BLACK EARTH REGION

The roots of the bladder are mainly used in the form of aqueous extracts, and the pharmacological effect is due to water-soluble compounds based on polysaccharides. The study of the peculiarities of accumulation of this group of compounds is relevant. The aim of this study the relationship between the accumulation of heavy metals and arsenic and biologically active substances in the roots of ordinary burdock, collected on the territory of the Voronezh region in biogeocenoses experiencing various anthropogenic effects. In the Voronezh region, 51 points of harvesting plant raw materials were selected. The study of the content of heavy metals and arsenic in the roots of the bladder, the sum of polysaccharides in terms of fructose and the sum of extractive substances extracted by water was conducted according to pharmacopeic methods. The total amount of gravimetrically precipitated water-soluble polysaccharides was determined by a previously developed and validated patented procedure. Correlation coefficients were analyzed to examine in detail the effects of heavy metals and arsenic on the accumulation of biologically active substances. Of the samples examined, some do not meet the requirements of the regulatory documentation for arsenic content. Significant physiological barriers have been identified to the accumulation of ecotoxicants in the roots of common burdock, which is especially noticeable for elements such as lead, mercury, arsenic, cadmium, cobalt and chromium. The raw material can selectively concentrate copper and zinc. In eight samples prepared under urbocenosis conditions, this indicator was below the minimum numerical value. Low correlation of the content of large sum of gravimetrically determined polysaccharides and extractive substances in samples of burdock roots was revealed. extracted with water, containing heavy metals and arsenic, wherein the numerical value of the sum of the polysaccharides in terms of fructose is largely dependent on the concentration of toxic elements in the plant; which is probably due to the formation of strong metal-monosaccharide complexes, which make it difficult to obtain colored complexes of monomer sugars with a complexing agent during spectrophotometric determination.

Експериментальні дослідження параметрів мікроклімату в салоні автобуса в холодну пору року

The paper analyzes the current state of research on microclimate parameters in bus cabins and identifies the main issues of the given topic. The authors analyzed and explained the importance of ensuring a favorable microclimate in vehicle cabins and assessed the risks of non-compliance. The relevance of the topic is confirmed by the existing scientific publications of foreign scientists who worked in this field and investigated similar issues. In addition to scientific works, an analysis of regulatory documentation in the world and Ukraine was conducted, existing problems and conflicts in requirements and parameters were considered. Theoretical knowledge is supplemented by experimental studies - the technical characteristics of the investigated bus are shown and the essence of the experiment is presented. Experimental studies were carried out in the passenger compartment of the Ukrainian-made Electron A18501 bus. Microclimate parameters such as temperature, humidity, and the amount of air throughout the passenger compartment in the cold season were measured using special equipment. Measurements were taken in the front, middle and rear of the bus cabin. A total of 4 conditional measurement zones were defined: zone 1 (between the wall of the driver's cabin and the passengers’ platform), zone 2 (in the area of the passengers’ platform), zone 3 (between the passengers’ platform and the rear door) and zone 4 (in the area of the rear door and the engine compartment), where the temperature and air humidity were determined at specific points. Measurements of the amount of air coming from the heating equipment (diffusers) were also made in certain locations. Analyzing the regulatory documents, in particular those used in our country, it was established that air temperature and humidity should be measured at the level of the feet and heads of passengers. There is no need to take measurements at waist level in vehicle cabins, unlike the driver's cabin, unless the bus is operated in very cold or very hot conditions. Since the climate in Ukraine is moderate, there is no need to carry out such additional measurements. The bus traveled along the route Ryasne 1-Levandivka-Sknyliv in Lviv during the experiment. This route fully corresponds to the city bus driving cycle, and its length is comparable to the value of the average city bus route. As a result of the experiment, it was determined that there are specific points in the cabin where the parameters of the microclimate do not correspond to the normative ones. These identified shortcomings require further research in order to improve the comfort of the microclimatic conditions in the bus cabin.

Recommendations are given for improving supervisory activities and introducing changes to the current regulatory documentation.

A COMPARATIVE STUDY OF THE COMPONENT COMPOSITION OF THE HERBS OF SOME SPECIES OF THE GENUS ACHILLEA L.

The article presents the results of a comparative study of the component composition of herbs of some species of the genus Achillea L. growing in the Samara region - common yarrow (Achillea millefolium L.), cartilaginous yarrow (Achillea cartilaginea (Ledeb. ex Rchb.) and noble yarrow (Achillea nobilis (L.). Spectrophotometry and high performance liquid chromatography were used as methods of investigation.
 As a result of comparative spectrophotometric analysis of water-alcoholic extracts of common yarrow herbs, yarrow cartilaginous herbs and noble yarrow herbs revealed that the absorption curve of their UV spectra is due mainly to hydroxycinnamic alcohols, in particular chlorogenic and caffeic acids (290 sh. and 330 nm). When aluminum (III) chloride solution was added to the water-alcoholic extracts of yarrow herb from the studied species, a bathochromic shift of the long-wave band at 400 nm was observed due to the flavonoids.
 The content of total flavonoids in the plant raw material is: common yarrow - 0.68±0.01%, cartilaginous yarrow - 0.65±0.02%, noble yarrow - 0.69±0.02%.
 Chlorogenic acid, cynaroside, cosmosiin, apigenin and luteolin were identified in water-alcoholic extracts from the above described species using HPLC method. In addition, the presence of caffeic acid was detected in the water-alcoholic extracts of noble yarrow herbs.
 The content of cosmosiin in the plant raw material is: common yarrow - 0.61±0.01%, cartilaginous yarrow - 0.56±0.02%, noble yarrow - 0.62±0.02%.
 The results of the study can be used in the development of regulatory documentation for medicinal plant material "Yarrow herb" for inclusion in the State Pharmacopoeia of the Russian Federation.

Determination of controlled parameters for designing a network for geotechnical monitoring of underground pipelines in the cryolithozone

Relevance. Determined by the need for geotechnical monitoring in the areas of distribution of permafrost soils for underground pipelines. The geotechnical system “permafrost soil – underground pipeline” is subject to the influence of exogenous geological processes during operation, cyclical changes in the state of soils of the seasonal layer of thawing and freezing, thawing of permafrost soils from the thermal effect of the pipeline, changing the plan-altitude position. The variety of schemes for interaction of the pipeline body with varieties of lithological structure of permafrost soils along the route should be worked out in detail at the design stage and also assessed in detail during geotechnical monitoring of the pipeline. The lack of regulatory requirements for the monitored parameters of underground pipelines leads to the use of non-standardized and varied monitoring networks from project to project. The lack of standard values ​​for the maximum deformations of an underground pipeline leads to the need to use calculation methods for determining the maximum deformations of the base and pipeline. The authors proposed the use of a comprehensive methodology for calculating underground pipelines, developed by employees of JSC TomskNIPIneft to determine the maximum permissible deformations of the pipeline at each point of the route with the presence of permafrost soils at the design stage, with further use of the results obtained as a controlled criterion when conducting geotechnical monitoring. Aim. To determine the controlled parameters for geotechnical monitoring of underground pipelines in the cryolithozone at the operational stage based on the application of a comprehensive methodology for calculating underground pipelines, as well as the formation of requirements for the system of information points. Methods. Review of the regulatory framework for geotechnical monitoring, analysis and evaluation of the applied methods and designs for monitoring underground pipelines, analysis of a comprehensive methodology for calculating underground pipelines in relation to the purposes of geotechnical monitoring. Results. Based on the results of the review of regulatory and technical documentation, the authors have revealed a lack of specification of methods, equipment, volume of the geotechnical monitoring network and frequency of pipeline monitoring, as well as the requirement for the use of the calculation method of limiting deformations and the lack of description of possible methods. A detailed analysis of the complex methodology for pipeline calculations, developed at JSC TomskNIPIneft, substantiates its use for geotechnical monitoring purposes, and notes the advantage of the methodology in the detail of the obtained limit values ​​of deformation with an accuracy of one meter along the axis of the pipeline route. The authors studied the methods and designs used for monitoring deformations of underground pipelines and established the compatibility of using a complex methodology with any design and method of monitoring. The paper introduces the list of the main monitored parameters and justification for the scope of the geotechnical monitoring network for underground pipelines.

Analysis of methods for modeling operating modes of compressor equipment that ensures the operation of field low-temperature separation units

Objective. A booster compressor station (BCS) is one of the key technological facilities necessary to ensure the effective operation of low-temperature separation technology for natural gas in field gas preparation systems for transportation. Ensuring promising operating modes of booster compressor stations with high efficiency is an urgent task. Method. One of the tools for solving this problem is mathematical modeling of the operating modes of centrifugal compressors (hereinafter - CPC), which are part of gas pumping units (GPU). The basis of the mathematical model is the gas dynamic characteristic (GDC) of the pulp and paper mill. The existing regulatory documentation presents simplified methods for modeling HDC, which are suitable for low-pressure pulp and paper mills with a pressure ratio of up to 1.5 and the number of compression stages of no more than three, but are not suitable for multi-stage high-pressure pulp and paper mills. Result. The results of a comparison of three methods of modeling the hydrodynamic characteristics (method of reduced characteristics, refined method of reduced characteristics, method of two-parameter approximation) of high-pressure pulp and paper mills are presented using the example of a pulp and paper mill with a pressure ratio of up to 2.0, intended for equipping a gas pumping unit as part of field booster compressor stations. An analysis and comparison of the obtained modeling results with actual data was carried out. Conclusion. When using the UMPH-2D modeling method, the smallest errors were obtained (no more than 2.0%), which, in turn, indicates its highest accuracy among the considered methods for recalculating the gas flow characteristics of high-pressure and multi-stage compressors.

Problematic issues of rationing and identification of the fat phase of dairy products

The purpose of the work: to identify problematic issues of rationing and detection of adulteration of milk and dairy products with fats of non-dairy origin of the fat phase and to propose ways to improve the rationing and application of methods of quality control of milk and dairy products in the practice of control and supervisory measures. To obtain the necessary data, legislative, regulatorytechnical and regulatory — methodological documentation, scientific publications and dissertations for the period from 2018 to 2023 were used. It has been established that at present, the detection of falsification of milk and dairy products within the framework of control and supervisory measures has a number of difficulties, which are related both to the legality of the use of existing control methods and regulatory framework, and to the informativeness of the control methods used and the relevance of the regulatory framework. To solve this issue, it is necessary to introduce new more inf into institutions that ensure the activities of Rospotrebnadzor new more informative control methods. One of which is the gas chromatographic determination of the triglyceride content in the fat fraction of the product, which makes it possible to detect the introduction of non-dairy components of less than 30 % and the use of animal fats as substitutes for milk fat. One of these methods is the determination of triglycerides of the fat fraction of the product, based on the extraction of lipids from the product sample, followed by direct gas chromatographic determination of their content. To evaluate products, it is necessary to adjust the regulatory documentation applicable to milk and dairy products, including the inclusion of clear identification indicators of the fat phase of milk fat in TR CU 033/2013 « On the safety of milk and dairy products».
