The article presents results of milk productivity analysis and calculation of the breeding value of cows (EBV) of different levels of productivity, using the BLUP ANIMAL MODEL methodology. The studies were carried out on Simmental cows from 14 regions of Russia, the total number was 61816 heads. The levels of development of the main parameters of milk productivity were assessed and a forecast of the breeding value of cows according to a number of parameters was obtained. It was found that productivity of Simmental cows born after 2005 is significantly higher: by +617 kg of milk (P≤0.001) and + 0.06% of protein in milk (P≤0.001), with a decrease of -0.02% of fat (P≤0.001), a service period of -4 days (P≤0.001) and the number of milking days by -20 (P≤0.001) in comparison with cows born earlier. Animals born after 2005 have higher EBV by mass fraction of milk fat with an average productivity of 5000 to 7000 kg of milk, where they have positive values in the range of + 0.0021 ... + 0.0041%, in comparison with cows born before 2005 years, which have negative values -0.0107 ... -0.0020%. As for EBV by mass fraction of milk protein of cows born after 2005, they had negative values in the range of -0.0037 ... -0.0008%, nevertheless, their values were much higher than the values of cows born earlier 2005 (values of -0.0057 ... -0.0028%). Sufficiently high correlation coefficients were obtained, r = 0.568 between phenotypic parameters of milk yield and its estimates, and r = 0.450 between parameters of the mass fraction of fat and its estimates.

The purpose of this study is to determine the relations between AgNOR characteristics, obtained by means of computer analysis, in populations of intact lymphocytes of hybrid sheep of different genotypes and to select parameters for functional assessment of nucleoli. The AgNOR state was studied in peripheral blood lymphocytes of hybrid sheep of three genotypes: purebred F1 Romanov sheep with argali (group 1), hybrids carrying 3/4 of Romanov sheep blood and 1/4 of argali blood (group 2), and hybrids with 7 / 8 blood of domestic sheep and 1/8 of argali blood (group 3). The number of argyrophilic zones (AgNOR), their total area (ΣSNOR), their average color density (DNOR), and average color density of the nucleus (DN) and its AgNOR-free area (DF) were taken into account. Parameters which characterize argyrophilic zones and the correlation coefficients between them were calculated in the samples of lymphocytes obtained from hybrids of different genotypes and from their generalized population. The study of the preparations was carried out on the equipment of the Altami company (Russia, S.-P.). Image processing and analysis were performed using the Image Scope 1.0 software (SMA, Russia, M.). The closest correlations exist between parameters of color density, which confirms an equal possibility of using them in assessing the state of argyrophilic zones. It was found that the correlation coefficients between different compared features have values from close to 0 to 1.0. The number of AgNORs in a cell, their total area and average density are characteristics that complement each other, since they are weakly correlated with each other. To assess the state of the nucleus -forming system, it is advisable to take into account mutually complementary features: the number of AgNORs, their total area, as well as the average optical densities of AgNOR (DNOR). The average nucleus density, closely correlated with DNOR values, can serve as an alternative to this parameter.

The article presents results of studies on milk productivity of crossbred first-calf heifers obtained by crossing Bestuzhev cows with red Danish bulls. Feeding of both groups (control and experimental) was carried out with proper and balanced ration. Total nutritional value of the ration was 14.07 energetic feed units (EFU). One EFU accounted for 85.15 g of digestible protein, dry matter per 100 kg of live weight - 3.6 kg, fiber from dry matter - 23%. Sugar - protein ratio of the diet was at the level of 0.8. As a result, crossbred first-calf heifers had higher parameters of milk yield (by 20.57%), fat content (by 0.23%) and protein (by 0.07%) in milk compared to pure-bred Bestuzhev peers; they had also higher milking capacity index (by 14.14%). In addition, crossbred first-calf heifers show better development, their live weight is 26 kg or 5.64% higher than the level of the breed minimum requirements. Consequently, the effect of heterosis is noted when crossing Bestuzhev cows with red Danish bulls, which has a positive effect on better development of crossbred heifers and on increase of their milk productivity. As a result, crossbred first-calf heifers meet the modern requirements of milk production technology on an industrial basis better than their Bestuzhev peers. Therefore, this method of crossing with the red Danish breed is advisable and should be used in selection and breeding work with the Bestuzhev breed.

Published: February 2022

Taking into account the growth of population, reduction of energy costs in food production is one of the urgent tasks of the human community. Metabolic energy is used for synthesis of new substances, is excreted from the body as part of milk, and is also converted into heat energy to maintain a constant body temperature of animals. The multi factor nature and complexity of the phenomenon currently does not allow to design a "metabolic map" of the genesis of gross feed energy into food for humans. Analysis of the problem (by methods of biological statistics) allows us to establish the most general concept and make a preliminary conclusion about the action and interaction of individual processes of using metabolic energy in a whole organism, to establish the value of independent factors - arguments and the influence of biological functions on the vital activity of animals. Improvement of isotherm by hereditary and technological factors contributes to growth of energy efficiency, productive animal husbandry.

The article analyzes the period of abnormally hot weather in the autumn and winter periods of 2019-2020 agricultural year, which was unprecedented and allowed the plants to overwinter successfully and even to go through a certain stage in their development and form a fairly high yield. It is a great anomaly with a typical return period of about 40 years. According to observations at Timiryazevsky agrometeorological post for 1990-2019, the average annual temperature increased by 1.04 ° С, atmospheric precipitation increased by 111.0 mm. The greatest increase of air temperature and atmospheric precipitation occurred in winter months. Analysis of wintering conditions for 2015-2020 agricultural years showed that positive temperature anomalies for the studied cold period of 2019-2020 reached up to 31.0 ° C. The amount of precipitation exceeded the average years long norms in November 2015 by 100 mm. Therefore, if earlier, the harvest of winter crops decreased due to freezing, as a result of snowlessness and severe frosts, then in recent years, soaking and asphyxiation played a certain role due to powerful snow cover. Such methods, as comparison, analysis and generalization of data, were used to process the analysis of the original data. To study the long-term changes of the periodic transformation function of the average annual temperature dynamics and the annual sum of atmospheric precipitation, the Fourier series was used and the parameters of the best sinusoidal approximation, the trend and the method of correlation, discriminant analysis were determined. The practical significance of the work was determined by the results of the research on the conditions for overwintering of winter crops and adaptation of agriculture to the changing conditions of the regional climate.

There is a great number of repeated and permanent spring wheat crops with insufficient areas occupied by forecrops of the first group in the grain-sowing zones of the Omsk region, which leads to a decrease of soil fertility, productivity and grain quality. The aim of the research is to reveal the influence of rapeseed forecrop on fertility, phytosanitary state of agrophytocenosis, productivity and technological properties of spring wheat grain in the forest-steppe of Western Siberia. Complex studies were carried out in a stationary crop rotation of Omsk Agrarian Scientific Center (rapeseed-wheat-soybean-wheat) in 2011-2017. The effectiveness of different intensity impact of soil cultivation systems in crop rotation and effectiveness of intensification means were studied in a two-factor experiment on meadow-black soil. The influence patterns of agricultural technologies on soil fertility elements, phytosanitary state of agrophytocenosis, productivity and technological parameters of grain were established. It was found that in case of intensity decrease of soil cultivation systems in a crop rotation, especially with limited application of intensification means, there is a spring wheat yield decrease after rapeseed forecrop by 0.17 t / ha. Grain yield increases to 2.88 t / ha in case of complex usage of chemicals, with a decrease of variability over years (variation coefficient) from 55 to 37% or by 1.5 times. The application of fungicides reduces the development and prevalence of infections on the upper layer of leaves and increases yield by 0.56 t / ha or by 27.5%. An increase of the mass of 1000 grains, the nature of grain, the content of protein and gluten was observed on the variant of intensive cultivation technology.

The paper presents results of study of the effectiveness of mineral fertilizers in the technology of spring wheat cultivation. Experimental studies were carried out on the experimental field of Ulyanovsk State Agrarian University in 2017-2020 in a five-field grain green manure crop rotation: green manure fallow - winter wheat - spring wheat - soybeans - barley. We studied change of grain yield and quality of spring wheat of Ulyanovskaya 100 variety in the experiment. Mathematical processing of the data showed that a significant increase of spring wheat grain yield was provided on the variants with fertilizer application at a dose of 40 and 60 kg / ha of active agent, which was 0.57 t / ha and 0.73 t / ha, respectively. At the same time, there was an increase of gluten amount up to 27.8% and improvement of its quality in the variant with application of fertilizers at a dose of 60 kg / ha of active agent (73 FDM units), which assigns it to the I quality group. The performed correlation-regression analysis made it possible to reveal the relationship between the grain yield of spring wheat and the conditions of its formation. A direct relationship was revealed between the yield and the background of crop nutrition (r = 0.64). It is important to note that the main factor which influences gluten accumulation in grain is mineral nutrition of plants (R2 = 0.55), the determination coefficient of the dependence of gluten accumulation on the hydrothermal index was R2 = 0.26. The research results showed a close relationship between the mass fraction of gluten and protein in the grain of spring wheat of Ulyanovskaya 100 variety (R2 = 0.70). The accumulation of protein varied from 264 (control) to 509 kg / ha (N60P60K60) within the research years.

Temperature is one of the most important abiotic factor, the critical values of which can have a negative impact at different stages of plant growth and development. The work shows the effect of this factor on corcule growth of different quality dill seeds obtained from different tillering parts. Experimental data indicate that the initial sizes of a corcule of the first tillering part are 34.6% higher than the second. A significant variation in morphometric parameters of dill seeds was noted including those characterizing the correlation of the corcule, endosperm and seed, both within individual parts and the plant as a whole. New data on the influence of high and low temperature factors on corcule growth of dill seeds from different tillering parts were obtained. First and second part corcules showed significant sensitivity to prolonged continuous exposure to increased temperatures during the upswelling period. Second-part seed corcules appeared to be more sensitive to temperature stress and reacted to it more explicitly. The corcule growth and germination of seeds slowed down in case of increase of the upswelling temperature to 30-35 ° C for the first part and 25-30 ° C for the second one. The physiological response to continuous increased temperatures (30-40 ° C) is a progressive inhibition of the corcule growth. The maximum temperature which allows corcule growth differs significantly for different tillering parts. When approaching the critical temperature (40 ° C), the differences are leveled. Significant (p <0.001) differences in dynamics of corcule growth in comparison with the control (20 ° C) were observed only at temperatures below 10 ° C for seeds of the first part and 15 ° C for seeds of the second part.

Knowledge of genetic nature of plant height parameter is important in order to detect short-stemming donors that shorten the length of the stem without deteriorating grain productivity. Identification of short-stemming genes and study of their selection significance in the genotype are used in selection of pairs of wheat varieties for crosses as short-stemming donors in new variety development. The aim of this work is to determine the variability and inheritance of stem length of soft winter wheat and to find a system of genetic control in specification of this parameter, using classical methods of assessment and DNA markers. The research was carried out at Federal State Budgetary Scientific Institution "Omsk Agrarian Scientific Center" in 2017 - 2020. The experiment had three-fold repetition. The object of the research is 3 varieties and 3 lines (LG2, LG3, LG4, Severnaya Zarya, Novosibirskaya 32, Omsk ozimaya), as well as 30 hybrids of the first generation (obtained according to full diallelic scheme) of domestic and foreign selection. Plant nutrition area was 10 x 20 (cm2). The forecrop was black fallow. Samples were screened with application of SSR marker of Rht8 gene. The experiment showed that demonstration of the trait in soft winter wheat descendants depends both on variety specificities and nuclear-plasma relationships. The donors of the "short-stemming" trait were identified: LG2 and Severnaya Zarya. Based on the statistical and molecular genetic analyzes (analysis of F1 hybrids, TCA (total combining ability) effects, as well as identifying the alleles of genes responsible for short-stemming), associations “DNA marker - TCA effect) were determined for the stem length parameter: LG2 (TCA = -1.23) ; Rht 8s (192 bp); Severnaya Zarya - (TCA = -1.21) = Rht 8s (192 bp). Lines of winter soft wheat carrying Rht 8s allele (192 bp) in their genotype, have a reduced stem height and can be recommended as sources of short stemming for usage in selection programs aimed at reducing plant height.

The most common reason for varietal impurities of long-stalked type in the crops of fiber flax is non-compliance with the basic requirements of internal control when working with several flax varieties on the farm or when carrying out a variety change. During field testing, the identification of biological impurity of the intermediate type is not completely carried out due to the unevenness of the crops. Due to morphological similarity of fiber flax varieties, it is impossible to determine the percentage of mechanical variety impurities of the long-stalked type. The aim of the research is to study the reproduction dynamics of variety impurity of K-7009 long- stalked form of flax, which has a yellow color of seeds, in the seeds of fiber flax contaminated with it after 6-year sowing. The aim is also to clarify the parameter of variety purity of fiber flax seeds of the following categories: genuine seeds (GS) and elite seeds (ES) in State Standard GOST R 52325-2005. The research was carried out in 2015-2020 in the field conditions of the Experimental field of the Federal State Budgetary Scientific Institution "Federal Scientific Center of Bast Cultures" in Tver region. The objects of the study were plants and seeds of Antey fiber flax variety (control). The usage of variety admixture of the long-stalked flax form with a marker trait made it possible to accurately determine its content in the crop in case of seed multiplication in nurseries of primary seed growing, superelite (GS) and elite (ES). It was found that variety contamination of fiber flax seeds with variety admixture in the amount of 0.2-1.0% did not affect the yield of seeds and straw. As a result of five-year reproduction of seeds in the crops of GS category, an increase in the amount of variety impurity was noted by 0.1-1.3%, in the ES category - by 0.3-2.1% compared to initial contamination. Based on the obtained experimental data, it was recommended to reduce variety purity index for the category of genuine fiber flax seeds in State Standard GOST R 52325-2005 to 99.5%, elite - to 90%.

Traditional methods of combating bacterial diseases of plants, including vascular bacteriosis of Cruciferous plants, do not currently allow to achieve effective result, which, among other things, is associated with the ability of phytopathogens to adapt to changing environmental conditions. Application of bacteriophages as antibacterial agents is a farsighted and effective direction in the field of plant protection. The aim of the study was to develop a technology for production and control of Xanthomonas campestris phage biological product, taking into account previously defined technological parameters. The objects of the study were X. campestris pv. campestris Cl34-UlSAU bacteriophage isolated from cabbage samples with signs of vascular bacteriosis from the fields of Ulyanovsk region, Staromainsky district. As a production strain, we used X. campestris pv. campestris Xc2 bacterial strain. The authors carried out studies on selection of suitable conditions, taking into account previously defined parameters: a method for bacteriophage removal from a production culture of bacteria, suitable passage time for production of a phage preparation, appropriate balance of phage and bacterial culture for cultivation, suitable temperature for bacteriophage cultivation. The paper introduces a scheme for production and control of Xanthomonas campestris pv. campestris phage biological product, which consists of 4 stages: sample preparation of a production culture of bacteria for compliance with the properties of the declared strain, sample preparation of a production strain of Kl34-UlSAU bacteriophage for compliance with its activity after storage, production of a phage product with reference to production scaling, pouring, purity control, bacteriophage titer, its specificity and spectrum of lytic action, storage of a biological product.

In this paper, we propose a traffic signal control method in intelligent transportation and geoinformation systems, based on a deterministic predictive model. The method provides adaptive control based on traffic data, including data from connected and autonomous vehicles. The proposed method is compared with the state-of-the-art traffic signal control solutions: empirical control algorithms and reinforcement learning-based control methods. An advantage of the proposed method is shown and directions of further research are outlined.

We discuss a range of problems relating to road pavement defects detection and modern approaches to their solution. The presented comparison of publicly available datasets allows one to make a conclusion that the problem of segmentation of road pavement defects in driver wide-view road images is difficult and poorly investigated. To solve this problem, we have developed algorithms for generating a synthetic dataset for cracks and potholes distress based on computer graphics methods and deep convolutional generative adversarial networks. A comparison of the accuracy of road distress segmentation was performed by training a fully convolutional neural network U-Net on real and combined datasets.

We discuss paraxial light beams composed of decentered Gaussian beams, with their phase selected in a special way so that their superposition is invariant as it propagates in free space, retaining its cross-section shape. By solving a system of five nonlinear equations, a superposition is constructed that forms an invariant off-axis elliptic Gaussian beam. An expression is obtained for the orbital angular momentum of this beam. It is shown that it consists of two components. The first of them is equal to the moment relative to the center of the beam and increases with increasing ellipticity. The second one quadratically depends on the distance from the center of mass to the optical axis (an analogue of Steiner's theorem). It is shown that the orientation of the ellipse in the transverse plane does not affect the normalized orbital angular momentum.

We study the propagation of optical vortices in a system which consists of a tandem of a multi-helical and twisted anisotropic fiber. We show that at certain resonance regimes of the optical fibers such a system allows one to control sign flipping of the topological charge and the circular polarization of the input optical vortex. Moreover, parameters of the multihelical and the twisted anisotropic fibers are established for the implementation of a logical operation that corresponds to the sequential executing of two fundamental SWAP and CNOT gates over the states of circularly polarized optical vortices.

Language is a way of communication with other people. People can make conversation through a set of words that become a sentence. There is one language that uses as the International language to communicate with other people who come from other countries in this world. Thus, English is used as an intermediate language for communication. One of nations, that use English to communicate, is the Philippines. The research found some phenomena that exist when Filipino speakers speak English. There were two objectives to be analyzed in this study: to find out the English words that the vowel is changing from English vowel into Tagalog vowel and identify the phonological process of Filipino speakers’ pronunciation in the vowel change. The phonological approach is used to solve the problem formulation of the research. The research analyzed a short movie entitled “Everglow” from the Philippines and analyzed the vowel changes in Filipino speakers’ pronunciation. The analysis showed that there were 11 English vowels changes in Filipino speakers’ pronunciation. Furthermore, three phonological processes were found in the vowel change, such as vowel lengthening, vowel raising, and vowel insertion. However, the most phonological process that was usually found in the vowel changes was the vowel lengthening.  Keywords: vowel change, Filipino, phonology.

The COVID-19 pandemic has had an impact on all aspects of life, including Indonesian banking. Furthermore, there has been a rapid growth of both Islamic and conventional banking industries. Therefore, this study aims to analyze the diﬀerences in the ﬁnancial ratios of capital adequacy ratio, non-performing loans/non-performing ﬁnancing, return on asset, return on equity, operating expense to operating income, as well as loan to deposit ratio/ﬁnancing todeposit ratio of Islamic and conventional banking during the COVID-19 pandemic. Acomparative analysis method was used with a quantitative approach, and data analysis was carried out using the independent sample t-test and the Mann-Whitney rank test. The results showed that during the COVID-19 pandemic, there were signiﬁcant diﬀerences in the ﬁnancial performance ratios of capital adequacy ratio, non-performing loans/non-performing ﬁnancing, return on asset, return on equity, operating expense to operating income, and loan to deposit ratio/ﬁnancing to deposit ratio for both Islamic and conventional banking. Moreover, conventional banking tends to have better ﬁnancial performance compared to Islamic bankingduring the COVID-19 pandemic. The implication of this study is that the public can ﬁnd out the ﬁnancial position of both Islamic and conventional banks and make comparisons to ascertain which one has a better ﬁnancial position in times of crisis.

Objective: In this study, the relationship between the Covid-19 vaccination rates in different countries and the performance of stock market indices were examined. The study aims to supply further evidence for policymakers to promote vaccination programs.

Methods: In the study, stock market performances and Covid-19 vaccination data of a total of 49 countries in the MSCI indices were used. Countries are sorted and grouped according to the date they reached the 10%, 50%, and 75% vaccination rates. Afterward, t-tests were used to determine whether there was a difference between the stock market returns of the countries in different groups according to their vaccination performances.

Results: This research shows that countries with rapid Covid-19 vaccination have lower volatility and higher performance in the stock markets. It has been determined that the stock market performances are higher in the countries which reached the 10% and 50% vaccination level of the population earlier. No statistically significant relationship was found between reaching the 75% vaccination level and the stock market performance. The first quartile of countries that completed 10% vaccination earlier have %9,7 higher stock market performance on average between 31.12.2020-28.05.2021 than the countries in the last quartile. Research results are also robust when tested separately for developed and emerging markets.

Conclusions: The results of the study show that vaccination has a positive contribution to financial markets. It is thought that the findings obtained in the research provide important information for investors and policymakers.

Published: February 2022

The aim of this study is to examine the effects of the pandemic process on immigrants in Turkey based on the findings of previous studies and to make policy recommendations based on the results obtained. The question of the research is “What are the effects of the pandemic process on immigrants in Turkey?” presented in the form. In order to answer this question, five sub-questions were sought in the study. In the study, in which qualitative research methods and techniques were used, the document analysis technique, which is one of the qualitative data collection techniques, was used to obtain the data to be used. In order to provide data for the study, first of all, national and international databases were searched by using keywords, word groups and subject headings that could provide data about the study subject. The documents obtained with the easily accessible sampling method were evaluated by considering the questions to be answered in the study. As a result of the evaluation, themes were created by taking into account the study areas covered in the researches. The data related to the themes created are transferred under the related theme title. Finally, quantitative data on the themes created are presented in a table. Although the data presented by the studies differ from each other, when these data are taken as a whole, it is seen that the majority of immigrants have information about Covid-19. However, the rate of immigrants accessing information through public institutions and organizations is very low. Social media and traditional media are the channels that immigrants use most in accessing information. In this process, some of the immigrants who applied to the hospital units had problems in accessing health services. A significant part of the children of immigrants did not have any problems in accessing distance education. A significant part of the immigrants had problems in accessing their livelihoods in this process. As a result of this situation, immigrants also experienced problems in accessing adequate food, shelter opportunities, energy resources and basic hygiene requirements.

Raffles's observations of the arts of visual culture in Java during his reign in 1811-1816
Authors: Iswahyudi
Published: February 2022

Raffles introduced government directly in Java and tried to do various things that he considered useful for his government. It abolished the slave trade, forced labor and permanent surrender of cash crops, and gave farmers the freedom to choose their own crops to grow. Later he also introduced the land tenure system, which abolished the unpopular forced farming system established by the Dutch, in which crops were grown and handed over to the government. In addition, he ordered the restoration of the Borobudur temple and other temples, and allowed research related to these cultural buildings. During his reign, Raffles increased his knowledge of Javanese customs, history, beliefs, geography, and natural history and compiled information for a book which he would later publish. This has a very big influence when it is associated with the end of the British rule in Java, it has a direct and indirect impact on the development of information and appreciation of the reception of art and culture observers of the indigenous Javanese population from Europe.

Analysis of mastery and application of the competency-based approach by area of knowledge in professors of the Autonomous University of Baja California (UABC, Mexico)
Authors: Ritchie Dr. Patricio Henríquez , Álvarez Mariscal MIriam
Published: February 2022

The aim of the research was to evaluate from the perception of university professors from four areas of knowledge of a Mexican public university the effectiveness of the competency-based approach regarding its application in the classroom. The dimensions considered were: syllabus; knowledge of the approach; application in the classroom; and perception of advantages and disadvantages of said approach. The sample consisted of 341 professors. Descriptive and comparative analyses were performed (chi-square). The main results, among others, show that depending on the area of knowledge a considerable percentage of professors are not familiar with the approach and they find it difficult to apply in the classroom; this regarding the type of teaching methods related to the approach as well as the learning assessment strategies used. It is also questioned the impossibility of the application of the approach in large groups. The development of this research, among other contributions, presents empirical evidence that contributes to the discussion on the difficulties and possibilities in the instrumentation of the competency-based approach in the classroom; the importance of assessing the institutional context; and the particularities of the area of knowledge where the approach is applied

The Role of the Presence of Aliphatic Alcohols on the Formation of Wormlike Micelle of Anionic-Cationic Surfactants Mixture
Authors: KHALİL Rabah , ALSAMARRAİ Liqaa
Published: February 2022

Thermodynamically controlled supramolecular gel or aggregate is commonly resulted from the formation of one-dimensional micelles through specific self-assembling of amphiphilic molecules. This phenomenon is commonly referred to as the formation of worm- or thread-like micelle which is still considered as quite complicated and obscure. This, in spite of the recent physical insight for interpreting this phenomenon, is referred to as the critical intermolecular forces (CIF) of which still needs further support. Therefore, attention by scientists in this field should be given in order to make this transition phenomenon clear. In this work, investigations concerning the effect of addition of aliphatic alcohols with different chain lengths of even carbon numbers (ethanol, 1-butanol, 1-hexanol, 1-octanol and 1-decanol), at different concentrations (0.002-0.040 M), and temperatures on the formation of wormlike micelle for the mixture of anionic sodium dodecylsulfate (SDS) and cationic cetyltrimethylammonium bromide (CTAB) surfactants were carried out. The formation of these one dimensional micelles were practically detected by following the sharp change of physical properties through the presence of a remarkable high viscosity peak. The results indicate there is no linear or systematic relationship between the effects of the presence of these alcohols with their chain lengths. It has been found that the presence of aliphatic alcohols causes a positive effect on the formation of one dimensional micelles. The ability of the transition from spherical to wormlike micelles increases with increasing their concentrations of alcohols except for that of 1-octanol. The obtained achievements were explained in terms of CIF theory which then offered a reasonable support to this theory. It was concluded that alcohols particularly ethanol and 1-octanol can be employed as adjustment reagents for controlling required viscosity of threadlike micelles.

Published: February 2022

Ko je leta 2020 pandemija COVID-19 zajela cel svet, so se izobraževalne ustanove zaprle in izobraževanje se je preselilo v domove izobraževancev. Posledično so se številne države soočile z izzivom nepričakovanega in pospešenega prehoda na spletno učenje. Napočil je ključni čas za razmislek o digitalni tehnologiji, pedagogiki in izobraževanju. Digitalna tehnologija je imela pomembno vlogo pri omogočanju učiteljem poučevanja na daljavo z uporabo orodij, ki so omogočala sinhrono in asinhrono komunikacijo s celotnim razredom, skupinami in posameznimi izobraževanci, dostop do učnih gradiv ter interaktivne in skupne dejavnosti. V prispevku obravnavamo elemente, ki so pripomogli oziroma omogočili izvedbo izobraževanja preko spleta, kot so digitalna tehnologija, modeli oziroma okvirji poučevanja s pomočjo mobilnih naprav, e-izobraževanje in druge. Poleg tega predstavimo tudi samo izhodišče za tako hiter prehod na izobraževanje preko spleta, to je izbruh pandemije COVID-19.
