THE ULTRASOUND APPLICATION IN THE PRODUCTION OF FERMENTED MILK PRODUCTS
Authors: Yaremchuk Oleksandr , Novgorodka Nadii
Published: June 2022

Fermented dairy products are one of the most important sources of essential amino acids, vitamins, trace elements and other biologically active substances that support the activity of the human immune system and reduce the impact of harmful environmental factors, so their daily presence in the diet is recommended.

The longest stage in the production of such dairy products is the fermentation process. This process requires the use of large volumes of production areas, and high energy consumption to maintain the temperature, so reducing the duration of the fermentation process without adversely affecting the consumer properties of products is a priority.

The development of various types of dairy products is also relevant, which is natively enriched with functional substances and does not require special additives, which translates it into the segment of natural and organic products, as well as reduces costs and increases the availability of certain medical diets.

The ultrasonic treatment of the fermented mixture is a promising tool for solving the tasks. In recent decades, ultrasound has proven to be a powerful and economical tool for changing the physical state of matter, dispersing, emulsifying, changing the rate of diffusion, crystallization and dissolution of substances, and activation of chemical and biochemical reactions.

It is becoming more widely used in various technological processes due to these properties, as well as the emergence of relatively inexpensive, efficient and reliable ultrasonic equipment that allows you to generate ultrasound of different frequency and intensity.

The control indicator in the research was to measure the increase in the active acidity of milk during fermentation by lactic acid mesophilic microorganisms. Thus, the possibility of using ultrasonic treatment as a factor in intensifying the fermentation process is proved.
INCREASING THE ULTRASONIC TECHNOLOGICAL ACTION EFFICIENCY IN THE FOOD RAW MATERIALS PROCESSING
Authors: Bernyk Iryna
Published: June 2022

The increase of ultrasonic technological action efficiency at food raw materials processing by taking into account their rheological properties is investigated. We have proved the need to determine the classification characteristics of food media, which are crucial for their processing and reflect the change in ultrasonic treatment. The mode of loading on the emitter, physical characteristics and conditions of exposure to the emitter are among the key features. It was found that acoustically unlimited media with constant and variable physical parameters with constant and variable dimensions have a significant impact on the processing. The efficiency of the oscillations in acoustically unlimited and limited environments is ensured by matching the value of the input resistance with the source of oscillations and with the waveguide system. Physical characteristics of food media, conditions of influence on the emitter are revealed. The identified classification features reflect the main key aspects of improving the efficiency of ultrasonic technological action in the food raw materials processing, which are related to the assessment of the waves’ propagation in the media and the interaction of these waves with the emitter. It is established that the Kelvin-Voigt model is one of the most reliable, it reflects the certain rheological properties of the medium in the conditions of ultrasonic cavitation treatment. Taking into account the conversion of ultrasonic energy, the main stages of the process are identified. The dependences of the amplitude of the sound pressure on the thickness of the fluid treatment layer are established, taking into account the viscosity of the liquid. The dependences of the radius of the cavitation bubble on the amplitude of the sound pressure and the thickness of the liquid layer are revealed. The wave resistance of the medium is studied and analytical dependences are obtained to determine the intensity of the technological process by which the increase of the efficiency of the processes of ultrasonic technological action in the food raw materials processing is realized.
MODELING OF TECHNOLOGICAL PROCESSES OF FILLING THE GEOMETRIC STRUCTURES OF THE WORKING BODIES OF A BUNKER TYPE OF AGRICULTURAL MACHINES WITH MATERIALS OF A SPHERICAL SHAPE
Authors: Dubchak Viktor , Pryshlyak Viktor
Published: June 2022

Optimization of geometric parameters of bunkers, feeders of agricultural machines depends on the type of process, mechanical and technological properties of materials, production technologies. Modern containers can be metal, plastic or glass. Growing requirements in a competitive market environment necessitate the constant improvement of existing and the creation of new machines with optimal parameters of the working bodies. Various agricultural materials, such as sandy soils, grain, fertilizers, tubers, fruits have different properties of flowability and mutual movement of particles in the form of spherical bodies. The article presents improved theoretical principles of practical orientation of optimal filling of containers with agricultural materials.

As a result of research on modeling of technological processes of filling geometric structures with working materials of spherical shape, using a fundamental analytical and mathematical apparatus, an algorithmic model that describes the optimal filling of space typical for seed boxes, harvesters or seeders has been developed. The maximum filling of a given flat and three-dimensional geometric figure by a set of balls of the same radius have been calculated, namely, the quantitative component of such optimal filling is described, and the criterion for estimating such filling is formed. Such processes occur during the production operation of seeders and planters, machines for harvesting and post-harvest processing of grain, root crops, fruits, etc.

The use of an algorithm for mathematical analysis and calculation of technological processes and technical systems provides the creation of the necessary conditions to prevent injury to seeds. In addition, innovative methods of theoretical analysis and calculation of processes, as well as phenomena characteristic of agro-industrial production have been proposed. These methods can be effectively applied in the educational process when preparing specialists for project activities.

Authors: Donskaya Olga , Polyakov Nikolay
Published: June 2022

Тhis article deals with the problem of implementing responsibility for evading the execution of punishments not related to deprivation of liberty. The authors of the article note that at present there is no really effective mechanism for implementing responsibility for evading serving a sentence not related to deprivation of liberty. The only existing form of implementing criminal executive responsibility for malicious evasion from serving a sentence not related to deprivation of liberty is to replace the punishment imposed by a court verdict with a more severe one.
The scientific article concludes that the concept of malicious evasion of punishment of one or another of the types under consideration should also be contained in the articles of the Criminal Code of the Russian Federation regulating these types of punishments. Proposals are being made to supplement the Criminal Code of the Russian Federation with relevant norms.

ISSUES RELATED TO THE ACQUISITION OF OWNERSHIP TO THE «ABANDONED» UNDOCUMENTED SHARES OVER THE ISSUER
Authors: Lazarenko L.B. , Bijieva A.U.
Published: June 2022

In the article, the authors describe problematic issues that have existed for many years, in the resolution of which issuers of shares are directly interested. In an effort to put the registers of shareholders in order, reflecting the existing shareholders in them, issuers faced the problem of «abandoned» shares, identifying inactive shareholders for many years for various reasons, including the lack of legal successors of a deceased individual or the liquidation of a legal entity. included in the register of shareholders of the issuer. The authors identified problematic issues related to the acquisition by the issuer of ownership of ownerless shares, since, on the one hand, the legislation does not provide for a mechanism for excluding inactive “deceased” shareholders from the register (this problem is especially acute in closed joint-stock companies, given the limited number of shareholders), which affects the rights and interests of the issuers of shares, on the other hand, violation of the rights of shareholders in the case of illegal alienation of shares through abuse and unfair actions of third parties (including raider takeovers). The absence in modern civil legislation of a clear definition of the status of a non-documentary security, its legal nature in relation to controversial legal relations, regulating property and obligations related to the acquisition of ownership of «abandoned» shares for the issuer, gave rise to disputes among theorists, and also influenced the formation of various judicial practice when considering claims of issuers of shares for the recognition of ownership of ownerless book-entry securities. In the article, the authors, analyzing the current legislation, including civil and securities legislation, the emerging judicial practice, offer their position when considering disputes over claims of issuers about rights to «abandoned» uncertified shares by recognizing by the court the ownership of ownerless («abandoned» owners ) shares for the issuer for their further distribution.

Authors: Obesnyuk Valery
Published: June 2022

Previously carried out measurements of tritium activity in surface waters or snow with a 10–1000x excess over the background away from industrial sites of nuclear industry enterprises cannot be associated with technological accidents. They fully comply with the standard technological regime peculiar to a specific design of a nuclear reactor. It is shown that the intensity of dispersion of tritium compounds is mainly responsible for turbulent diffusion in “the flare” of the exhaust pipe, even during calm. This fact can be used to organize quantitative control of emissions to atmosphere during the year.

Published: June 2022

The article devotes to algorithm for the instrumental spectrum correction of a CdTe detector in the low-energy X-ray region with a cutoff energy < 150 keV. By minimizing the influence of the detector’s response function, the algorithm allows the instrumental spectrum to be reconstructed, approaching its shape closer to the true one. Particular attention is paid to the low-energy region with the boundary energy up to 100 keV. For a given region, the algorithm makes it possible to correct the spectrum taking into account the difference between the theoretical efficiency curve and the modeled efficiency curve. The main goal of developing an improved algorithm is to determine the characteristics of the radiation quality of an X-ray facility.
Direcciones del yeísmo en España: nivelación dialectal e integración sociolingüística
Authors: Molina Martos Isabel
Published: June 2022

Se estudia el yeísmo en su dimensión de cambio lingüístico panhispánico, planteando la necesidad de una metodología coordinada que permita la comparabilidad de su evolución en las distintas regiones de la geografía del español. La ausencia de unidad metodológica lleva a reflexionar sobre las dificultades de entender la dirección del proceso desde una perspectiva global. Desde este planteamiento se ilustran a través de los análisis realizados en las ciudades de Madrid y Málaga (España), en el marco del “Proyecto para el Estudio Sociolingüístico del Español de España y América” (PRESEEA), las perspectivas sobre las que puede arrojar luz la aplicación de una metodología comparada. La innovación oscila entre dos polos: el dialecto y la variedad estándar, generando soluciones nuevas que configuran regiolectos. A su vez, a las dinámicas niveladoras del dialecto se superponen las situaciones de variedades en contacto que se derivan de los movimientos migratorios.

Authors: Banks Briony , Connell Louise
Published: June 2022

We present a database of category production (aka semantic fluency) norms collected in the UK for 117 categories (67 concrete and 50 abstract). Participants verbally named as many category members as possible within 60 seconds, resulting in a large variety of over 2000 generated member concepts. The norms feature common measures of category production (production frequency, mean ordinal rank, first-rank frequency), as well as response times for all first-named category members, and typicality ratings collected from a separate participant sample. We provide two versions of the dataset: a referential version that groups together responses that relate to the same referent (e.g., hippo, hippopotamus) and a full version that retains all original responses to enable future lexical analysis. Correlational analyses with previous norms from the USA and UK demonstrate both consistencies and differences in English-language norms over time and between geographical regions. Further exploration of the norms reveals a number of structural and psycholinguistic differences between abstract and concrete categories. The data and analyses will be of use in the fields of cognitive psychology, neuropsychology, psycholinguistics, and cognitive modelling, and to any researchers interested in semantic category structure. All data, including original participant recordings, are available at https://osf.io/jgcu6/.

Study of Honeycomb Air Curtain for a Freezer Room to Enhance Protection against Warm Air Infiltration
Authors: Peem Pongsupat  , Juntakan Taweekun  , Piyanut Saengsikhiao
Published: June 2022

The objective of this research is to present the energy-saving effect of applying an air curtain to prevent the penetration of warm air through a freezer door. Retail business is highly competitive in many aspects, including the factors affecting the cost of the store. The most important cost for many businesses is the cost of supplying energy to refrigeration systems. Therefore, the operator must try to reduce the energy consumption of the freezer room. Normally, a freezer room consumes cooling energy when its door is opened for the loading and unloading of goods, leading to the infiltration of warm air from outside. For this reason, we conducted experiments in which air curtains were used. We compared two types of air curtain grille: Common and honeycomb. The experiment was designed to assess whether the honeycomb grille could provide a stronger air curtain and more effectively prevent the penetration of warm air. For the experiment, we used a freezer with a temperature of −25 ๐C. The freezer room door measured 200 × 100 m2 and an air curtain was installed 5 cm above the outer freezer door. The velocity of the air curtain was 6.5 m/s. Simulations were carried out using solid workflow simulation software. The changes in temperature and air velocity were simulated in the room, considering three scenarios: Type 1: Leaving the freezer door open for 1 hour without the air curtain operating. This resulted in warm air inflow at the top of the door and cold air outflow at the bottom of the door. When a steady-state was reached, the room temperature was 6.05 ๐C. Type 2: Leaving the freezer door open for 1 hour, using an air curtain with a common grille to prevent the infiltration of warm air. The results showed that an air curtain could prevent the infiltration of warm air. The outside air tries to push through the air curtain, which can be seen from the curvature of the air curtain line in the model. When a steady-state was reached, the room temperature was −2.41 ๐C. Type 3: Leaving the freezer door open for 1 hour, using an air curtain with a honeycomb grille to prevent the infiltration of warm air. The honeycomb grille air curtain was slightly better at preventing the infiltration of warm air than the common grille. There was less curvature in the air curtain line, which means that the strength of the air curtain is greater. When a steady-state was reached, the room temperature was −2.64 ๐C. In conclusion, the results demonstrated that the honeycomb grille air curtain can prevent the infiltration of warm air 9.54% better than the common grille air curtain.

The issues of improving thermal comfort inside the building have become a global point of research interest attributed to the realization that people spend more than 90% of their time in the indoor environment. This study investigated the thermal comfort temperature range for indoor open spaces in second level of the Universiti Tun Hussein Onn Malaysia (UTHM) library. The study conducted through subjective measurement (thermal sensation questionnaire) and physical measurement (air temperature, relative humidity, air velocity, mean radiant temperature measurement). A total of 120 occupants completed the thermal sensation questionnaire of indoor open spaces for morning and afternoon sessions for six days. Physical measurements data were also collected at eight measurement sampling point across the indoor open space for six days. The linear regression analysis for air temperature with thermal sensation vote (TSV) and predicted mean vote (PMV) for both morning session and afternoon session shows a good fit of the regression model on the observed data. It shows 70% of the variation in the output variable of TSV and PMV can be explained by the input variables of air temperature. The thermal comfort temperature ranges for TSV of -0.5 to +0.5 were within the range of 24.17 ºC to 25.01ºC for morning session and 23.63 ºC to 24.20 ºC for the afternoon air temperature. In addition, the thermal comfort temperature ranges for PMV of -0.5 to +0.5 were 24.03 ºC to 25.15 ºC for morning session and 23.70 ºC to 24.47 ºC for the afternoon. By using linear regression equation, the relation between air temperature, PMV and TSV were obtained.

This paper presents the impingement flow study on the temperature profile perforated plate. Icing is one of the most hazardous threats in aviation and this leads to unsafe flight conditions. Hence, thermal anti-Icing is very much useful in aircraft to prevent ice accretion on the surface. On the other hand, the hotspot temperature of this technique might destroy the Aluminum-based Bias Acoustic Liner (BAL) plate. Thus, it is highly essential to study the hotspot temperature profile on the perforated plate. This study is concerned with a numerical study of the convective heat exchange between an impinging air jet at temperatures of 70 °C and a structured perforated surface using the Fluent tool. The model is designed in an Aluminium plate with the dimensions of 100 mm x 100 mm x 1mm containing 0.15 cm diameter perforated hole. In addition, the 0.25 cm diameter circular nozzle is maintained at a constant jet-to-target distance of 3.71 cm. In this sense, the standard k-ω turbulence model jet equation is applied to this three-dimensional domain with periodic boundary conditions for the Reynolds numbers ranges from 2000–9000. The simulations are performed based on the gap between two holes and the hole configuration (tandem and staggered) at different jet velocities. The simulation results reveal that there is a rapid increment in heat transfer with Reynolds number and the maximum local Nusselt number decreases by seven and increases to 24 when the Reynolds number varies from 2508.17 to 8778.588 at the surface of the perforated plate. The findings of the hole arrangement on the perforated plate indicate that the tandem hole configuration without a center hole is highly recommended for bias acoustic liners than the staggered configuration. Since the tandem hole arrangement has higher dimensionless temperature, a thicker high temperature layer will be developed at the outer surface. Hence, this kind of perforated plate is more suitable to prevent ice accretion in aircraft applications.

Among the many health monitoring techniques for structures, one relatively new technique is based on electromechanical impedance (EMI) measurements. The goal of this investigation was to see if the EMI approach could be used to assess the health of metallic structures. In order to achieve this objective, the feasibility of numerical simulation of piezoelectric transducer – structure interaction in the field of the EMI technique to perform structural health monitoring using commercial finite element (FE) software, ANSYS was investigated. The numerical simulations were carried out to find the effect of different types of damage such as crack and to investigate the effect of temperature on the crack detection. When compared to experimental impedance responses found in the literature, where EMI is used to monitor different undamaged and damaged structures made of steel and aluminium, the developed FE models successfully obtained similar results with good agreement. This research revealed that the FEM could be a good alternative to experimentation for studying the EMI approach.

Boilers are widely used in industries to produce steam. In some sectors, the steam generated is utilized directly in the production line for heating. Certain industries use steam to produce electricity. Fire tube boilers are limited to generating steam for processing; meanwhile, water tube boilers are widely used in electricity generation besides steam generation for processing lines. Subcritical boilers, supercritical boilers, and Heat Recovery Steam Generator (HRSG) are types of boilers commonly used to produce high capacity steam. This review article focuses on the optimization of HRSG operational efficiency. Industry players are keen on the improvement of operational efficiency since these directly influence the operating cost. Steam pressure, steam output, heat transfer efficiency and temperature distributions are key areas comprehensively reviewed in this article. Generally, improvement studies on boilers are not feasible to conduct during operation. Therefore, the scaled-down model used in the experiment or the boilers CFD models are simulated to understand the characteristics of the boilers. This review article is expected to overview HRSG boiler efficiency improvements and factors influencing boiler operational parameters.

AbstractMaluku as an archipelagic province requires a comprehensive understanding. Given the diverse characteristics of the region, of course, a good understanding is needed to maintain and maintain the integrity of the region. Various cultures, ethnicities, religions, are such a large capital to maintain the ecosystem of life that exists in each region. The diverse life style of the Maluku people, of course, contains various characters of different people's lives. Communities inhabit areas that are mostly known to be coastal areas, so the cultural character of the people will also be different from those in mountainous or inland areas. The environment in which they live their lives has shaped the character of their society. The awareness of the community to protect and maintain the environment has shown that the dependence of the local community on the environment itself is very high. Therefore, awareness in understanding the background of the ecosystem of life in each region is very important.Keywords: Environment, Communication.

Adult giraffes reach heights of 4.5 meters with a heart-to-head distance of over 2 meters, making cranial blood supply challenging. Duplex ultrasound confirmed that the giraffe jugular vein collapses during head movement from ground level to fully erect, negating the possibility of a siphon mechanism in the neck. We showed that in a collapsible tube, flow is significantly influenced by a short length siphon structure over a simulated head to heart distance for a giraffe, with the length of the siphon structure determined according to brain case measurements.

Background: this research on E-learning was geared towards determining how E-learning policy pedagogy influences student-centred collaborative learning and development in higher institutions. Objectives: the objectives were to determine: the effect of E-learning on students' achievement; the extent of the relationship between learner-centered pedagogy and students' performance; the extent to which students-centered collaborative learning affect development. Design: 246 was realised as sample size using Topmans formula at 5% level of tolerance and 95% level of confidence from infinite population. Questionnaire was used to collect data, 246 copies of the questionnaire were distributed and 230 copies were returned. Method: Descriptive research method was adopted for the study. Three hypotheses were tested; the first and the third were tested using linear regression while the second was tested using Pearson product moment correlation coefficient statistics. Findings: The findings show that E-learning had a significant positive effect on students' achievement; secondly, there is a significant relationship between learner-centered pedagogy and students' performance; thirdly, Student-centered collaborative learning had a significant positive effect on development. Result: Teachers, students and other administrative staff should be involved in the full utilisation of the educational system of teaching, learning and the use of modern information and communication technologies (ICT). Recommendation: The study recommends that for e-learning to be effective, E-learning facilities should be appropriately maintained. Stable internet should be provided to support easy and fast learning and teaching; the staff and students should learn the basic knowledge on how to operate the computer and its peripheral devices; electricity is a basic requirement needed for the computer and its peripheral devices to function, so government should ensure that all institutions are connected to a stable electric grid.
