Development of sublimation drying modes of rose hip fruits Freezing drying of rose hip

The aim of the study was the selection of effective modes of rosehip sublimation dehydration. An Iney-6M unit was used for freeze drying. The selection of the duration of the sublimation stage and the final drying temperature was carried out. At the same time, such indicators as the duration of drying, organoleptic assessment and the preservation of vitamin C were analyzed. The duration of freeze drying of rose hips with a period of sublimation of 4, 5, 6 and 7 hours was 6, 7, 8 and 8.5 hours, respectively. It was found that with a decrease in the duration of the sublimation stage, a decrease in the quality characteristics of dry rose hips is observed. It was found that when the drying temperature changes from 70 to 40 °C, the drying time increases from 6.5 to 9.5 hours. At the same time, the loss of vitamin C also decreases. Based on the research, the most favorable modes of sublimation dehydration of rose hips have been determined - the final drying temperature is 50 °C and the duration of the sublimation stage is 5 hours. Under these modes, the duration of lyophilization is 8 hours, the total organoleptic assessment is 18.25 points out of 20, and the preservation of vitamin C is 27%. Lyophilized rose hips can be used as an independent product, or ground into powder for adding to other products - confectionery, dairy, bakery products, as well as biologically active additives and functional food.

Enhanced large-scale validation of satellite-based land rainfall products

Satellite-based precipitation estimates (SPEs) are generally validated using ground-based rain gauge or radar observations. However, in poorly instrumented regions, uncertainty in these references can lead to biased assessments of SPE accuracy. As a result, at regional or continental scales, an objective basis to evaluate SPEs is currently lacking. Here, we evaluate the potential for large-scale, spatially continuous evaluation of SPEs over land via the application of collocation-based techniques (i.e., triple collocation (TC) and quadruple collocation (QC) analyses). Our collocation approach leverages the SM2RAIN (Soil Moisture to Rain) rainfall product, derived from the time series analysis of satellite-based soil moisture retrievals, in combination with independent rainfall datasets acquired from ground observations and climate reanalysis to validate four years of the EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites) H-SAF (Satellite Application Facility on Support to Operational Hydrology and Water Management) H23 daily rainfall product. Large-scale maps of the H23 correlation metric are generated using both TC and QC analyses. Results demonstrate that the SM2RAIN product is a uniquely valuable independent product for collocation analyses, as other available large-scale rainfall datasets are often based on overlapping data sources and algorithms. In particular, the availability of SM2RAIN facilitates the large-scale evaluation of SPE products like H23 – even in areas lacking adequate ground-based observations to apply traditional validation approaches.

A method to measure activities in the digital economy

Subject. We make our own method to evaluate the economic value of activities as part of the digital economy and examine its impact on the national economy and Russia’s GDP, in particular. The article presents the digital economy of Russia in figures. We make suggestions on the use of new sources of data, methods for data collection and processing, which would be consistent with the modern digital reality. Objectives. We carry out our own comprehensive study into the measurement of the digital economic activity, present our own method and the respective outcome. Methods. Considering specific goals and objectives, we applied economic, economic-mathematical, statistical, logic and other methods of research, data processing and summary. Results. We present our own technique for measuring the economic value of the digital economic activity in the Russian Federation. Conclusions and Relevance. There are several methods for such measurements in the world. Each of them have its own strengths and weaknesses. We devised an independent product promising to become a recognized statistical study for purposes of the digital economy measurement.

MEASURING ACTIVE FERRITE ANTENNA AFA-1M

В статье описана малогабаритная широкополосная активная ферритовая антенна АФА-1М для измерений магнитных полей в диапазоне частот от 10 Гц до 300 кГц. Антенна может быть использована как самостоятельное изделие, так и в составе автоматизированных измерительных комплексов для измерения электромагнитных полей помех, а также для проверки системы защиты информации от непреднамеренной утечки за счет побочных электромагнитных излучений. The article describes the small-sized broadband active ferrite antenna AFA-1M for measuring magnetic fields in the frequency range from 10 Hz to 300 kHz. The antenna can be used as an independent product and as a part of automated measuring systems for measuring electromagnetic fields of interference, as well as to verify the protection of information from unintentional leakage due to spurious electromagnetic radiation.

Model and algorithm of hierarchical control of technical parameters of automatic spacecrafts at autonomous and complex tests

We consider the problem of rational statistical control technical parameters of automatic spacecraft (AKA) in the process of their ground testing in autonomous and complex testing in a three-tier hierarchical structure: independent product testing, independent testing systems and comprehensive testing of the AKA in general. The mathematical model of control, the formalized statement of a problem and algorithm of optimization of statistical control of sets of products and their technical parameters on hierarchy of working off is given. At the same time, the model and algorithm allow you to select the optimal product range of each level of the hierarchy from the sets that are subject to mandatory control, take into account the specified requirements for technical parameters and the results of monitoring the technical parameters of the lower levels of products when planning and carrying out control of the parameters of the higher levels.

Marketing of Experience in Creating of Value Product

The brand experience is considered as an independent product or economic proposal. The stages of growth of consumer value of the goods depending on his level of condition and price segment are considered. The article presents the dynamics of the formation of the consumer value of the product in terms of its trademark depending on the stage where the product is located in the processing chain production-consumption in the system of marketing management. The mechanism of value creation in marketing impressions is developed. The effect assessment of impressions on the model of «emperor with no clothes» is proposed.

Maximizing the Competitive Value of Product Design Innovation: Re-framing and Re-aligning the Design-Business Relationship

This paper focuses on the contribution of the independent product design industry to business and strategy development processes of contemporary organizations. It embarks from the observation that whilst some policy-makers and enlightened businesses recognize the role and value of design beyond the traditional and narrow confines of technical or ‘commodity’ input, many fail to understand its potential as a transformative tool. Applying evidence from three empirical studies, and taking the perspective of design creative, the paper addresses three questions: why is it that product designers have encountered resistance in their efforts to promote themselves as well-placed and knowledgeable providers of strategic development intelligence and advice; what proven contributions can product designers offer with respect to their client’s business development planning?
