Perception of Medial Consonants by Children With and Without Speech and Language Disorders: A Preliminary Study
Authors: Brosseau-Lapré Françoise , Schumaker Jennifer , Kluender Keith R.
Published: April 2020

Purpose

The aim of this preliminary study was to investigate perception of the early-acquired consonant /p/ and later-acquired consonant /ʃ/ in medial word position by preschoolers with and without speech and language disorders.

Method

Twenty-four children, six with isolated speech sound disorder (SSD-only), six with SSD and concomitant developmental language disorder (SSD + DLD), and 12 with typical speech and language skills (TD) completed a battery of standardized speech and language tests as well as an identification task of /aCa/ disyllables. Targets and foils varied by only one place, manner, or voice feature. Mixed analysis of variance (participant groups × two target consonants) was conducted to compare performance of children in the three groups (between-subjects) and to compare performance on consonants that are early acquired or later acquired (within-subject).

Results

All groups of participants were more accurate in perceiving the early-acquired consonant than the later-acquired consonant. Overall performance by children with SSD-only did not differ significantly from children with TD. As a group, children with SSD + DLD were less accurate than children with TD and children with SSD-only for both target consonants.

Conclusions

Children with SSD + DLD performed less well than peers with SSD-only and with TD with both predictably easy and difficult sound contrasts. Children with SSD-only performed nominally less well than children with TD for the speech sound with which they have difficulty, but this difference did not reach statistical significance for these relatively small group sizes.

Authors: Vasilenko N V , Linkov A J , Tokareva O V
Published: April 2020

Clustering of services in the conditions of digital economy development is considered as a way of their integration with the purpose of increasing customer satisfaction, as well as that of strengthening the competitive position of service organizations based on the promotion of green consumption. Services are clustered with the aim of satisfying one main or several interconnected needs of individuals or businesses taking into account the degree with which the consumer influences the process of service delivery. This paper demonstrates how clustering of services can be used to solve sustainability problems. It is shown that digital technologies allow the service provider to customize a service to fit the needs and requirements of a particular consumer within the first type of clustering in the service sector, and they are also included in the service support of the main service within the second type of clustering. Moreover, these technologies have their own value for the consumer within the third type of clustering and provide tools for the fourth type of clustering. In general, digitalization promotes technologization and cooperation in service clusters. The authors suppose that further research can be done into how the types of clustering mentioned manifest themselves in different industries.

Published: April 2020

The food-borne micronutrient deficiency causes diet-related diseases. The problem is part of great challenges and demands a solution. The human body is the most vulnerable to selenium deficiency. The physiological requirement in this micronutrient is, in one respect, small – 70 mg per day, on the other hand, it causes a number of serious diseases. The experience was obtained of providing the population with micronutrients. It is possible to include biologically active supplements, vitamin and mineral preparations (VMP) into the ration, direct micronutrient supplementation into food products at the production stage, fortification of animal feedstuff, etc. Fortification of plant raw material with selenium during the growing stage was studied. Further, the fortified plant raw material is supposed to be used in prophylactic food products manufacturing. The most common plants with high biologically active substance (BAS) content, including selenium were chosen. They are certified and widely used in pharmacology and food industry. The most prospective concentrator agent is sweet-clover. The fortification technology for hydroponically grown sweet-clover was carried out in laboratory. Growing of the plant was carried out on hydroponics by putting it into the natural environment system. For achieving the optimum the following factors were varied: the content and concentration of the medium; the concentration of selenium preparation; temperature, humidity and dormancy period of the plant. It was established that the plant consumes selenium well in combination with the definite set of biologically active substances from the medium. As compared to the original selenium content (0.312 mg/kg of dry raw material) its quantity reached 3.50±0.80 mg/kg after fortification. Total selenium content in sweet-clover may be forecast with allowances for the preset parameters. It is advisory to continue the research on adapting the plant fortification technology using selenium preparations on commercial scale. The allowances should be made for climatic conditions, supplementation method, strength of the solutions, growth environment.

Authors: Karpov Denis , Sinitsyn Anton
Published: April 2020

An algorithm for integrated non-destructive diagnostics of technical condition of structures of buildings and constructions using the temperature field analysis is proposed. An attempt is made to systematize, characterize and build a logical sequence of stages for energy inspection of heat-consuming and heat-generating construction objects and their structural elements. The presented algorithm differs from the well-known technologies for energy monitoring of buildings and structures by the presence of two additional steps, which are an integrated part of any energy examination: determination of the relative surface humidity of building structures and the actual mass flow of coolant through a heating system using qualitative and quantitative assessment of thermal images. The implementation of energy (thermal imaging) and technical examinations according to the presented structural scheme requires appropriate equipment, as well as involvement of highly qualified specialists (civil engineers, thermal power engineers, thermal physicists, thermal imaging operators, etc.).

Authors: Kuznetsova Tatiana , Ivanchenko Olga , Trukhina Elena , Nikitina Maria , Kiseleva Anastasia
Published: April 2020

The metabolism of Chlorella sorokiniana is subjected to changes caused by various cultivation conditions. If dosed ultraviolet radiation is used, there is a possibility of a compensatory increase in the synthesis of carotenoids which prevent oxidative stress. Strain 211-8k was cultured under various lighting conditions: control sample was subjected to fluorescent light; sample 1 was subjected to dosed periodic ultraviolet irradiation for 15 minutes every day and fluorescent lighting; sample 2 was subjected to ultraviolet irradiation for 30 minutes in the stabilization phase. Periodic UV exposure negatively affects the population growth of C. sorokiniana which was possible to detect only on the ninth day and the biomass yield significantly decreased. A single UV exposure for 30 minutes lead to a slight decrease in the yield of air-dry biomass which with a further population growth may be compensated. Periodic exposure to UV radiation stimulates carotenoids synthesis, the yield in terms of dry biomass exceeded the control sample on average by 30%. A single ultraviolet irradiation for 30 minutes in the stabilization phase lead to a decrease in the biomass content of both chlorophyll and carotenoids. Microscopy of microalgae showed that ultraviolet radiation leads to the formation of cells with signs of apoptosis.

Authors: Mukhametshina Elvina , Aitov Ibragim
Published: April 2020

The article describes an innovative method of volumetric assessment and certification of oil-contaminated land plots, which allows us to give an accurate assessment of the volume content of some limiting factors (in this work we considered such factors as oil pollution, chloride concentration and pH). This technique involves building 3D models, tabular systematization of concentrations and volumes of oil pollution, and improving the certification of the above-mentioned areas using special QR codes and parcel codes created by us. The method described by us makes it easier and at the same time increases the objectivity of certification of oil-contaminated land plots, reflects the qualitative and quantitative volume-time parameters of plots, increases the convenience, efficiency and reliability of accounting, data transmission and storage. To speed up the processing of information, we suggest using new forms of its representation (parcel codes). Parcel codes are an intermediate link for creating QR codes.

Published: April 2020

The authors propose the evaluation of the level of development of waste management and the factors associated with effectiveness of waste management in the world. Scientific novelty consists in new principle of the selection of factors. This principle based on the balance between the rate of waste generation and the efficiency of utilization, depending on income level in the countries. As a result, the factors affecting the effectiveness of waste management selected and classified by the method of expert evaluation. The algorithms has been proposed for calculate of the indicators of the intensity of waste generation, of the efficiency of utilization, of the balance of waste, of the overall efficiency of waste management. The evaluation of the effectiveness of waste management was applied by method of score of 217 countries of the world for 2018. The study found a correlation between the effectiveness of waste management and the country’s per capita income. This evaluation allows classifying countries on the level of per capita income and by the types of balance between the intensity of waste generation and the efficiency of waste utilization. On this basis the authors proposed to form a balanced policy of waste management.

Published: April 2020

Perfection of technological processes, both in preliminary preparation of raw materials and during the final mandatory step of pasteurization, plays a key role in ensuring the quality of finished products, which is important in the production of canned dietary products. The aim of the research was to develop a more efficient way of blanching raw materials with its hardware and soft pasteurization modes, which will allow the production of high quality and competitive compotes for functional nutrition. We have developed and proposed a method of pulse-steam blanching of raw materials directly in glass jars with saturated water vapor, instead of the traditional method using hot water. The essence of the method is as follows. Fruits stacked in jars are pulse heated for 100–160 seconds (depending on the volume of the container) with saturated water vapor with temperature of 105–110 °C, and then fed into jars with cycles of 10 and 10 seconds respectively. The use of pulsed supply of saturated water vapor contributes to achieving more even heating of the fruit, which are characterized by a relatively large internal thermal resistance, causing overheating of the surface layers, and also provides an increase in the temperature of the product, which allows to pour into the jars syrup at relatively high temperature (97–98 °C), while the traditional technology accounts for the temperature of only 80–85 °C. Implementation of this method ensures the temperature level of the product entering the pasteurization stage being 78–80 °C, as opposed to the traditional method, where the temperature of the product is 45–48 °C. After that, the jars will be filled with syrup with a temperature of 97–98 °C, sealed and sent for pasteurization on accelerated modes. To implement the new method of blanching, the design of the device for pulse-steam blanching of fruits in glass jars has been developed. New thermal sterilization regimes have been developed, taking into account the increased temperature of the product after sealing and improved technology for the production of pear compote. The results of physical and chemical testing confirm the high quality of the finished product.

Published: April 2020

The article is devoted to development of prediction methodology for potential damage from misuse of agricultural lands such as accommodation of oil and gas industry facilities, transport, infrastructure complexes, and emergency management. The purpose of the research is to propose a methodology for determination of potential damage to territory from misuse of agricultural lands. In order to do this, the following objectives need to be achieved: - group the sources of damage from agricultural lands misuse based on empirical evidence; - determine and classify the main types of damage and their periods; - develop the methodology and mathematical apparatus for calculation and prediction of damage extent on the “municipal district-region” level; - predict the losses from agricultural lands misuse in accordance with conditions of the Samara region. The proposed methodology allows one to more accurately assess the damage to large territories (district, region, country), which is essential to the work of administrative bodies. For calculation purposes, all cases of agricultural lands misuse are divided into four categories, each of which has its features of damage development. The obtained methodology was tested in the Samara region, where annually from 2.5 to 4.0 thousand ha of agricultural lands are used for other purposes than intended. Note that more than 20% of this number is removed from use for a long period of time (for more than 10 years). Oil spills account for 2.3-4.0% of land misuse. In 2021 the resulting damage could amount to 1.9 billion rubles.
Models of Frequency Characteristics of Ecological Systems and their Conversion to Sound Form
Authors: Bogomolov Alexander , Nevezhin Victor , Piskun Elena , Khokhlov Vladimir
Published: April 2020

Real-time monitoring of the state of ecological systems can contribute to early warning of their deviation from an equilibrium state (homeostasis) or a change that leads to a threat to human health or existence. In addition to the existing means of monitoring the state of ecological systems and models for predicting the assessment of their state in the future, it is proposed to use models of the frequency characteristics of these systems, monitoring of which can detect signals about the appearance of unwanted deviations from homeostasis in the form of a change in the frequency spectrum. A change in the frequency spectrum can be converted into the sound waveform, which will allow timely detection of this undesirable change in the state of the ecological system. As a new information channel and analysis of the dynamics of the state of ecological systems, in the article it is proposed to use the wavelet transform of time series with the subsequent translation of the totality of their harmonic vibrations into sound form. In contrast to the Fourier transform, in which the spectrum of stationary and non-stationary processes is practically indistinguishable and it is impossible to determine the moment of the appearance of a new harmonic, the wavelet transformation gives this opportunity. In addition to the purely utilitarian application of the conversion of the vibrational characteristics of an ecological system into sound form, it becomes be possible to convert them into the “music” of ecological systems, which may give a new direction for creative understanding of the state of nature.

Published: April 2020

We resolved the issue of eliminating unauthorized dumps of municipal solid waste (MSW). The MSW placement problem attracts special attention of the urban residents in the Russian Federation. However, the number of unauthorized MSW dumps in our country continues to increase. The accumulation of municipal waste in certain localities of urbanized centers, as well as in unauthorized dumps near residential areas is a serious problem for the environment and human health. MSW decomposition products lead to chemical, physical, and biological pollution of the lithosphere, hydrosphere and atmosphere. It is difficult to eliminate unauthorized dumps of municipal solid waste, since it is virtually impossible to have advance knowledge about the places of their formation. The objects of our investigation were MSW dumps. We conducted laboratory studies on the composition of wastewaters from the areas of unauthorized dumps within Saratov region, and discovered that precipitation-generated runoff from unauthorized dumps contained manifold excesses of toxic pollutants (heavy metals, organic matter, etc.). We proposed an original method for converting unauthorized dumps of solid household waste into the MSW landfills. The method includes two components: vertical planning of previously formed dump volume and annular surrounding drainage of the open type. The drainage ditch is connected to the water-collecting well, which is linked to the water storage tank joined, in its turn, to the water treatment plant.

Published: April 2020

The amount of electronic waste is growing annually all over the world, today it is almost 45 million tons. Less than 20% of electronic waste is being decontaminated and recycled. The rest is being taken to landfills or to places which are not supposed to store hazardous waste. This increases the adverse impact on the environment due to the fact that the waste consists of over 50% of hazardous components. At the same time, it also contains rare and expensive metals including indium. To extract indium from electronic waste it is necessary to justify the method of leaching. For this purpose research on leaching of indium from mobile phone screens has been done using various acids and parameters of the leaching process. As a result of the analysis, 6 methodologies were tested with various acid concentrations, the contact time of solid matter with a chemical reagent and temperature. The results of experimental research on the determination of metal concentration in mobile phone screens and the analysis of methods on indium leaching from mobile phone screens into a solution for further research are presented.

The article is devoted to the topical problem of rational use of energy and nutrient content of feed in obtaining livestock products (milk) from cows by shifting the energy balance of the animal’s body towards “productive energy”, i.e. the synthesis of fat and proteins. The authors would like to point out that one of the main factors influencing fluctuations in the energy balance of an animal are microclimate parameters, as the deviation of the microclimate parameters from the established optimal limits leads to a reduction in milk yields by 10 to 20%. Therefore, the aim of our work is to develop an energy-saving technology for the formation of optimal microclimate in livestock facilities using air conditioning systems, which can regulate most of the parameters of the microclimate inside them, namely: temperature, relative humidity and internal air velocity, concentration of harmful gases (carbon dioxide, ammonia, and hydrogen sulfide), dust and microorganisms. The presence of the mode enabling recirculation air purification allows to save heat energy and energy coming with feed by up to 50% compared with typical microclimate systems. To this end, we have systematized separate data from scientific researches done by various scientists in the fields of animal hygiene and veterinary medicine and obtained dependencies of influence of microclimate parameters (temperature, relative humidity, internal air velocity) on the productivity of animals (cows) and feed consumption.

The relevance of the study of the genesis of theoretical and methodological foundations of the formation of innovative investment agricultural organizations’ policies appears under the pressure of technological transformation in the sustainable development of the economy. The beginning of the 21st century is marked by frequent cycles of both development and stagnation of economic trends. Disclosure of the transformation ontology involves identification of changes in all the functional processes of the studied object, including the relationship of the subject (active or passive activity) to objects and instruments of influence. Markers and indicators measuring the level of quality and the return efficiency of transformed objects are also subjects to changes.

Published: April 2020

Socio-ecological problems are relevant, both at the global and at the national and regional levels. In 2020, much attention is paid to ecology. Due to environmental problems, it is planned to switch from a standard economic linear model to a circular economy. The authors considered the theoretical side of the circular economy, as well as the principles of such a model. The article discusses the existing scheme for the disposal of municipal solid waste, and also shows a new scheme for the disposal of municipal solid waste in the Arkhangelsk region as part of the EcoTechnoPark Shiyes project. The article discusses both the positive and negative aspects of this project. The authors conducted a sociological survey among the population of the Russian Federation, where it was proposed to evaluate the attitude to the EcoTechnoPark Shiyes project and the possibility of organizing separate waste collection. At the end of the article, possible solutions to the problem of recycling solid waste are suggested, options for adaptation and motivation of the population to solve this problem are considered.

People are exposed to a significant amount of man-made hazards upon contact with technological systems, and foundry engineering industrial sites belong undoubtedly to such systems. Foundry shops are characterized by high noise and temperature thresholds that affect the human body. Unsatisfactory condition of the air is considered to be an acute problem in foundry engineering. In this connection, the state of air and its composition change, which can certainly affect health of workers, and the latter may be seen in the respiratory, cardiovascular, nervous systems, and digestive organs functional changes. However, up to date, the effect of health hazards of foundry engineering on the microbiocenosis of human intestine remains poorly studied. The paper apprizes the microbiota of human large intestine being exposed to integrated effects of foundry engineering factors. A structural change of the intestinal coenotype accompanied by a change of absolute dominants and opportunistic microorganisms appearance is established. Intestinal microbiocenosis disorder is accompanied by a high detectability of parasitic protozoa Blastocystis spp. in the sampling material. The obtained blastocyst isolates have pathogenic properties of varying degree of manifestation, which indicates their unequal etiological significance in the development of the pathological process. The isolated strains of protozoa have a high anti-interferon activity characterizing their persistent properties. This characteristic brings along the displacement of normal symbionts by blastocysts and colonization of the intestinal mucous membranes with these protozoa.

The purpose of the work was to study some safety indicators of the fat component of instant noodles, the most popular brands in the Russian Federation, and to predict their potential effects on the human body. The subject of the study was the physicochemical changes of the extracted fat component from fast food products. The most popular instant products - instant noodles of 3 popular brands were selected as the objects of research. According to the results of studies, it was noted that the mass fraction of compounds insoluble in petroleum ether is more than 1% - 1.2 and 1.1, respectively, and exceeds the recommended norms for deep fat. The content of epoxides exceeds the recommended allowable level of 17-24 mmol/kg by almost 2-2.2 times. The increased content of fat oxidation products is a potential risk factor that provokes diseases of the gastrointestinal tract, cardiovascular and immune systems, as well as changes in the blood formula. The data obtained indicate the need for a critical assessment of production technology, as well as the advisability of introducing regulatory standards regarding the safety control of the fat component of fast food products in order to reduce the effects of toxic products of fat oxidation on the human body and, as a consequence, reduce the prevalence of civilization diseases.
