The rapid progress of water-dispersion paint and varnish materials from the group of waterborne is due to a number of their advantages in comparison with other paint and varnish materials from the category of environmentally friendly. They provide the possibility of low-temperature drying up to room temperature. The purpose is to establish the electrical conductivity and degree of dissociation of surfactants (surfactants) PAN and PES. The methodology of the work included the determination of the specific electrical conductivity (χ, mSm/cm) and the hydrogen index (pH) in freshly prepared and seasoned (at least 48 h) solutions with different additive contents (C = 0÷4 g/dm3) at T = 298 K. Introduction. It was found that at comparable concentrations in water (from 0.25 to 4 g/dm3), PAN is characterized by a greater range of changes in specific electrical conductivity (from 6.21 to 16.97 mSm) than PES (from 3.48 to 4.11 mSm). According to experimental data, sodium polyacrylate is a polyelectrolyte dissociating in water to form polyacrylate macroanions. The degree of dissociation of PAN in dilute solutions (0.25 g / dm3) is maximum and is 28 %. An increase in concentration (From 0.25 g/dm3) is accompanied by a decrease in α to the level of 8 % at SPAN = 4 g/dm3. Polyethersiloxane copolymer, in turn, is a weaker electrolyte than PAN. The degree of dissociation of its macromolecules in dilute solution (0.25 g/dm3) is 1.5 times less and is 19%). In the region of elevated concentrations (СPES = 4 g/dm3), α does not exceed 2 %, that is, 4 times lower than in the isoconcentration solution of PAN. Dissociation of amphiphilic compounds is accompanied by the release of slightly acidic functional groups, which provides a shift in the hydrogen index. With respect to bidistilled water (pH = 5.4), pH gradually decreases to a minimum level of 4.26 in PAN solutions and 4.64 in PES solutions. As the duration of the exposure of the solution increases, the change in α and pH is due to the accumulation of hydrolysis products, after 48 hours in the isoconcentration solutions of PAN and PES, the values of the hydrogen index changed by 0.1-0.8 and 0.1-0.4, respectively.

Biodiesel is a new replacement for various types of traditional fuels. There are many advantages of biofuel including renewable, less-flammability, and cheaper compared to traditional fuel, reduce greenhouse gas emissions, and others. However, the primary challenge of biofuel production in the large-scale production is related to purification of its unwanted impurities such as glycerol, water, methanol, soap/catalyst, free fatty acids, glycerides and others. Herein, glycerol is an unwanted impurity of biofuel that leads to problems including i) deposition in the bottom of fuel tank, ii) decantation, iii) engine durability problems, iv) setting problems, v) injector fouling, vi) storage problem, and others. Consequently, there are many ways to remove glycerol, and herein, the one alternative is extraction of glycerol from biodiesel via Natural Deep Eutectic Solvents. In this regard, the mixture of a methyltriphenylphosphonium bromide and ethylene glycol, as a Natural Deep Eutectic Solvent ais effective in removing glycerol from biofuel. In this work, we had investigated the formation mechanism of methyltriphenylphosphonium bromide and ethylene glycol, as a Natural Deep Eutectic Solvents, and then extraction of glycerol from biofuel via Natural Deep Eutectic Solvents via implementing Quantum Chemical Calculations using HyperChem software. The results imply that there are strong ionic and covalent interactions between bromine, methyltriphenylphosphonium and ethylene glycol according to optimized structures, bond length, energies, and others. Secondly, the extraction of glycerol from biofuel is mainly achieved via bromine ion of Natural Deep Eutectic Solvent, and the structure of Natural Deep Eutectic Solvent is remaining unchanged after this process, meaning its stability, and can be reused.

Thermal performance of copolymer based on polyethylene glycol fumarate and methacrylic acid in a dynamic mode, in an inert nitrogen environment are considered in the present work. Kinetic evaluation of thermal decomposition process was conducted using three different data processing methods (Friedman, Ozawa-Flynn-Wall, Kissinger-Akahira-Sunose). Utilizing a mixed-method approach kinetic triplets Eа, A, g(a) were received. The received kinetic parameters were used to calculate the thermodynamic characteristics of Gibbs energy (∆G), enthalpy (∆H) and entropy of activation (∆S). Copolymer thermal gravimetric analysis (TGA) and differential thermogravimetric analysis (DTA) curves were studied under nitrogen environment using a heating rate of 2,5, 5, 10 or 20°C/min. The method of Invariant Kinetic Parameters was used to identify the reaction model and pre-exponential factor. The main phase of copolymer decomposition was set, which occurred within a narrow temperature interval and is evidenced by the spike on the differential curve. Values for 13 reaction models were received. Utilised methods resulted in a proper energy activation alignment within 223-229 kJ mol-1. Design and experimental data provided close values. TGA and DTA curve analysis has shown a sufficient thermal stability of these copolymers under the nitrogen environment.

Digital financial inclusion is important to achieving the Sustainable Development Goals. Digital financial tools, such as mobile money, can, in principle, be used by anyone with a cell phone. Mobile money and services surrounding mobile money can help reduce poverty by helping increase remittances from labour migrants, helping households to weather negative shocks to income, and encouraging investments such as in farms or in self-employment activities. An extension of this logic is that, in refugee hosting areas, digital financial inclusion through mobile money can potentially play a role in improving the economic inclusion of refugees. This evidence brief shares findings from a project developing a mobile money system in the Somali region of Ethiopia and discusses ways that policies can help catalyse the use of mobile money in such regions.

Abstract

Horror is a popular video game genre, which has the ability to induce strong emotions such as fear and anxiety. Horror game sound partly derives from movie soundtracking, but the interactive and immersive nature of video games and game music challenges the traditional beliefs concerning the meaning and importance of sound design and soundtracking. In this review article, we discuss the relationship between the sonic design of horror games and experienced anxiety. We combine musicological and ludological viewpoints with clinical and neuropsychological ones to create a multidisciplinary overview of the subject. We will also discuss the paradox of how we can enjoy fear and anxiety inducing media, despite those emotions having a very negative association. Finally we will discuss the possible advantages of combining music and video games for the study of emotions in music, video games and psychology.

Analisamos neste artigo a hipótese de que teria havido no Brasil, em paralelo ao processo de redução da desigualdade de renda observado no início do século XXI, o encolhimento da classe média, como sugere estudo de Morgan (2017), ao apontar o grupo intermediário de renda (os 40% do meio da distribuição) como os “perdedores” relativos do processo redistributivo verificado no país entre 2001 e 2015. Utilizamos as PNADs 2001-2015 e uma metodologia indutiva para identificação da classe média com o intuito de examinar as características socioeconômicas desse grupo intermediário e a sua dinâmica distributiva interna, e assim verificar se é pertinente sua classificação como “classe média” e se, de fato, o grupo poderia ser considerado um perdedor relativo desse processo. Nosso exame desse grupo não confirma a interpretação de classe média perdedora.

This study seeks to perform production forecasts of gas wells using the concept of decline curve analysis (DCA) and regression analysis. The regression analysis was performed by fitting a polynomial curve fitting model to a set of production history data, so as to determine the initial gas flowrate. In addition, Gauss Jacobi method was used to provide a solution to the solved five-by-five matrix in order to compute values for the regression coefficients. Subsequently, a computer program “ROTEX” was developed to predict the efficacy of the proposed DCA and regression analysis method. Three wells (WELL Y1, Y2 and Y3) from a field in the Niger Delta region were evaluated with respect to forecasting future gas rates till abandonment. Consequently, Well Y1 was observed to have the potential to continue producing for the next 30 years, while Well Y2 and Y3 have the potential to produce for roughly five years before they reach abandonment. R-squared values were computed for each case, as a means to validate the integrity of the fitted regression curves to the production history data. All R-squared values were observed to be very close to unity and are thus considered reliable.

Artificial lift methods are used in oil wells when the natural energy of the reservoir is not enough to bring the reservoir fluids at the surface. Therefore, these methods are used to add the missing energy. There are many types of artificial lift methods with different characteristics. The selection of an artificial lift technique for a well is crucial because it influences long-term well production and operating costs. In our paper, we propose an application that allows a quick screening and selection of the best artificial lift technique. The application uses Boolean logic as a mathematical and conceptual approach. The model is based on a memory set of data which is working like a database and compares the information in order to select the best artificial lift method for a well data set. The results are presented in two layers such as a front page used for input data set and a second one where it will be displayed the selected method and its advantages and disadvantages.
Measurement report: Radiative efficiency estimates of (CF3)2CFCN, CF3OCFCF2, and CF3OCF2CF3 using high-resolution Fourier transform infrared spectroscopy

Abstract. Absorption cross-sections (ACS) of emerging greenhouse gases (GHG) were measured to estimate the radiative efficiencies (RE) using high-resolution Fourier transform infrared spectroscopy (HR-FTIR). For quantitative spectroscopy, the Beer–Lambert parameters of absorber pressure, temperature, and optical pass length (OPL) have been accurately determined to be traceable to the primary standards. The OPL of the multipass cell (MP) mounted on the HR-FTIR spectrometer was spectroscopically calibrated. A ratio of the averaged N2O absorptions was measured in the range of 2,217.4–2,219.0 cm-1 with a spectral resolution of 0.026 cm-1, yielding a ratio of OPLs between the MP and reference cell (RC). This cell-to-cell comparison (CC) method does not include the uncertainty in the referring line strength, thereby reducing the calibration uncertainty compared with a direct line-strength referring method. With the OPL-calibrated MP (3.169 ± 0.079 m), the ACSs were measured at low absorber pressures with a spectral resolution of 2 cm-1, integrated at 10 cm-1 intervals, and multiplied by the new narrow band model to yield the RE values. The RE values of the classic GHGs CF4, SF6, and NF3 were evaluated to be 0.085 ± 0.002, 0.573 ± 0.016, and 0.195 ± 0.008 W m-2 ppb-1, respectively, which are consistent with previously reported values. For the emerging GHGs, the RE values were determined to be 0.201 ± 0.008 W m-2 ppb-1 for (CF3)2CFCN (heptafluoroisobutyronitrile, commercially referred to as Novec-4710), 0.328 ± 0.013 W m-2 ppb-1 for CF3OCFCF2 (perfluoro methyl vinyl ether, PMVE), and 0.544 ± 0.022 W m-2 ppb-1 for CF3OCF2CF3 (1,1,1,2,2-pentafluoro-2-(trifluoromethoxy)ethane, PFMEE).

Abstract. Emission controls have substantially brought down aerosol pollution in China, however, aerosol mass reductions have slowed down in recent years in the Pearl River Delta (PRD) region, where secondary organic aerosol (SOA) formation poses a major challenge for air quality improvement. In this study, we characterized the roles of SOA in haze formation in urban Guangzhou City of the PRD using year-long aerosol mass spectrometer measurements for the first time and discussed possible pathways of SOA formations. On average, organic aerosols (OA) contribute dominantly (50 %) to non-refractory submicron aerosol mass (NR-PM1). The average mass concentration of SOA (including by less and more oxidized OA, LOOA and MOOA) contributed most to NR-PM1, reaching about 1.7 times that of primary organic aerosols (POA, including hydrocarbon-like and cooking-related OA) and accounting for 32 % of NR-PM1, even more than sulfate (22 %) and nitrate (16 %). Seasonal variations of NR-PM1 revealed that haze formation mechanisms differed much among distinct seasons. Sulfate mattered more than nitrate in fall, while nitrate was more important than sulfate in spring and winter, with SOA contributing significantly to haze formations in all seasons. Daytime SOA formation was weak in winter under low oxidant level and air relative humidity, whereas prominent daytime SOA formation was observed in fall, spring and summer almost on daily basis, suggesting for important roles of photochemistry in SOA formations. Further analysis showed that the coordination of gas-phase photochemistry and subsequent aqueous-phase reactions likely played significant roles in quick daytime SOA formations. Obvious nighttime SOA formations were also frequently observed in spring, fall and winter, and it was found that daytime and nighttime SOA formations together had resulted in the highest SOA concentrations in these seasons and contributed substantially to severe haze formations. Simultaneous increases of nitrate with SOA after sunset suggested the important roles of NO3 radical chemistry in nighttime SOA formations, and confirmed by continuous increase of NO+/NO2+ fragment ratio after sunset. Findings of this study have promoted our understanding in haze pollution characteristics of the PRD and laid down future directions on investigations of SOA formation mechanisms in urban areas of southern China that share similar emission sources and meteorological conditions.
Remote sensing of aerosol water fraction, dry size distribution and soluble fraction using multi-angle, multi-spectral polarimetry

Published: December 2022

Abstract. A framework to infer volume water fraction, soluble fraction and dry size distributions of fine-mode aerosol from multi-angle, multi-spectral polarimetry retrievals of column-averaged ambient aerosol properties is presented. The method is applied to observations of the Research Scanning Polarimeter (RSP) obtained during two NASA aircraft campaigns, namely the Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) and the Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP2Ex). All aerosol retrievals are statistically evaluated using in situ data. Volume water fraction is inferred from the retrieved ambient real part of the refractive index, assuming a dry refractive index of 1.54 and by applying a volume mixing rule to obtain the effective ambient refractive index. The uncertainties in inferred volume water fraction resulting from this simplified model are discussed and estimated to be lower than 0.2 and decreasing with increasing volume water fraction. The daily mean retrieved volume water fractions correlate well with the in situ values with a mean absolute difference of 0.09. Polarimeter-retrieved ambient effective radius for daily data is shown to increase as a function of volume water fraction as expected. Furthermore, the effective variance of the size distributions also increases with increasing effective radius, which we show is consistent with an external mixture of soluble and insoluble aerosol. The relative variations of effective radius and variance over an observation period are then used to estimate the soluble fraction of the aerosol. Daily results of soluble fraction correlate well with in situ-observed sulfate mass fraction with a correlation coefficient of 0.79. Subsequently, inferred water and soluble fractions are used to derive dry fine-mode size distributions from their ambient counterparts. While dry effective radii obtained in situ and from RSP show similar ranges, in situ values are generally substantially smaller during the ACTIVATE deployments, which may be due to biases in RSP retrievals or in the in situ observations, or both. Both RSP and in situ observations indicate the dominance of aerosol with low hygroscopicity during the ACTIVATE and CAMP2Ex campaigns. Furthermore, RSP indicates a high degree of external mixing of particles with low and high hygroscopicity. These retrievals of fine-mode water volume fraction and soluble fraction may be used for the evaluation of water uptake in atmospheric models. Furthermore, the framework allows us to estimate the variation in the concentration of fine-mode aerosol larger than a specific dry radius limit, which can be used as a proxy for the variation in cloud condensation nucleus concentrations. This framework may be applied to multi-angle, multi-spectral satellite data expected to be available in the near future.
Spatial characteristics of frazil streaks in the Terra Nova Bay Polynya from high-resolution visible satellite imagery
Authors: Bradtke Katarzyna , Herman Agnieszka
Published: December 2022

Abstract. Coastal polynyas around the Antarctic continent are regions of very strong ocean–atmosphere heat and moisture exchange, important for local and regional weather, sea ice production and water mass formation. Due to extreme atmospheric conditions (very strong offshore winds, low air temperature and humidity) the surface ocean layer in polynyas is highly turbulent, with mixing due to combined Langmuir, wind-induced and buoyancy-driven turbulence. One of the visible signs of complex interactions between the mixed layer dynamics and the forming sea ice are frazil streaks, elongated patches of high ice concentration separated by areas of open water. In spite of their ubiquity, observational and modelling analyses of frazil streaks have been very limited, largely due to the fact that their significance for heat flux and ice production is only just becoming apparent. In this study, the first comprehensive analysis of the spatial variability of surface frazil concentration is performed for the Terra Nova Bay Polynya (TNBP). Frazil streaks are identified in high-resolution (pixel size 10–15 m) visible satellite imagery, and their properties (surface area, width, spacing and orientation) are linked to the meteorological forcing (wind speed and air temperature). This provides a simple statistical tool for estimating the extent and ice coverage of the region of high ice production under given meteorological conditions. It is also shown that the orientation of narrow streaks tends to agree with the wind direction, suggesting the dominating role of the local wind forcing in their formation. Very wide streaks, in turn, deviate from that pattern, as they are presumably influenced by several additional factors, including local water circulation and the associated convergence zones. An analysis of peak wave lengths and directions determined from the images, compared to analogous open-water wave lengths computed with a spectral wave model, demonstrates a significant slow-down in the observed wave growth in TNBP. This suggests an important role of frazil streaks in modifying wind-wave growth and/or dissipation in polynyas.

In this study, a salt-tracer method applicability in Quaternary aquifer system groundwater was tested. The tracer experiment was performed in Vilnius University Kairėnai polygon for hydrogeological investigations in 2021. In Lithuania, experiments with tracers are not prevalent. Therefore, this work describes the practical use of the tracer for the analysis of the hydrogeological environment, a methodology that enables experiments with salt tracers. After the tracer test, the water flow rate was calculated at the time of the peak concentration of Cl-, which reached 9.41 m/d. The effective porosity value was calculated manually (0.16) and using TRAC code (0.1389 and 0.1341; normalized for background values). The main results of tracer experiments show that sodium chloride solution is effective as a tracer in the Quaternary aquifer system of Lithuania for actual nef calculation, where aquifer hydraulic conductivity values are similar to the studied area. Tracer peak analysis performed in this study confirms a possibility of estimating the heterogeneity of aquifer nef on site.

Farewells and language usage: Multilingual practices in Bolzano merchants’ documents
Authors: Meluzzi Chiara
Published: December 2022

Research on historical sociolinguistics has seen letter writing as a social practice which could present many instances of multilingualism. Merchants’ language management is also of particular importance for the role of traders in language contact and change. In this work, merchants’ correspondence from the town of Bolzano will be considered across the 18th and 19th century, by considering letters written by the Georg Anton Menz textile company to its correspondents. These letters have been preserved (and partly digitalized) in the archive of the Chamber of Commerce in Bolzano. The analysis will focus on language distribution, as well as on multilingual practices in closing formulas. It will be shown how the relative status of the languages involved changed over time, and how an Italian closing formula (addio, farewell) was used also to close German letters. This probably correlates on a specific writing style in use in the Habsburg Empire but uncommon for Italian commercial letters.

Authors: De Marco Anna , Palumbo Mariagrazia
Published: December 2022

he present study investigates the use of Discourse Markers (DMs) in the context of Italian migration varieties using an onomasiological approach, i.e. looking at the functions that DMs entail in conversation. Thus, this study focuses on intergenerational variation, namely, how the use of DMs in terms of their functional space varies across generations. We will consider only the metadiscoursive functions, i.e. all the microfunctions aiming at structuring the discourse, ensuring clarity and affecting the organization of discourse. They are analysed in two generations of Italian migrants living in Munich. Data are taken from a corpus of audio recorded interview with 13 Italian migrants living in Munich (average length of each interview, 30 minutes). Results point out that the second-generation informants DMs undergo both a gradual loss of types and a gradual reduction of tokens.

Investment Dispute Settlement Mechanisms under the Recovery of CalvoismReform Practices and way forward
Authors: Jillani Abid Hussain Shah , Habib Rao Imran , Razzaq Muhammad Umair , Raza Muhammad Muneeb
Published: December 2022

As the recovery of the Calvo Doctrine is becoming more and more apparent, the reform practice of the investment dispute settlement mechanism is also affected. The world's major economies have practiced different reform models according to their actual conditions, broadly categorized into the radical abandonment model represented by Latin American countries, the partial improvement model represented by the United States, and the institutional innovation model represented by the European Union. The essence of the Calvo Doctrine's "non-intervention" core corresponds to the field of investment dispute settlement, which is mainly reflected in the host country's opposition to the superior treatment of foreign investors over domestic investors, thus excluding investment disputes from being handled by international investment arbitration bodies. China, as the initiator of the "One Belt, One Road" initiative, should follow the trend of Calvo Doctrine recovery in the current reform of the investment dispute settlement mechanism, re-examine the international investment arbitration mechanism based on dialectical analysis of different reform proposals of various economies, explore and build a preventive and alternative approach based on investment dispute prevention and dispute mediation, and respond to the needs of the international community. To address the crisis of the legitimacy of the current investment arbitration under the revival of the Calvo Doctrine, we will explore the investment dispute settlement mechanism under the "One Belt, One Road" initiative from a new perspective with a distinctive Chinese solution.

Although effective, most treatments for perfectionism are inaccessible to the general population, and are time-, resource-, and cost-intensive. Online single-session interventions (SSIs) display promise in preventing and treating negative mental health symptoms; however, no studies have examined the effectiveness of an online SSI targeting perfectionism. To address this, the present study sought to evaluate a novel computerized, self-guided SSI. The two primary aims of the study were: 1) to assess the intervention’s acceptability, likability, and utility, and 2) to examine whether the intervention reduces perfectionistic attitudes, depression, anxiety, and stress in a college student population. At baseline, students at a liberal arts college (N=79) were randomized to receive a 40-minute perfectionism SSI or a stress-management control. Participants rated the perfectionism intervention as highly helpful, acceptable, and likable. The perfectionism intervention was associated with greater improvements in perfectionism, depression, anxiety, and stress; however, the differences in reductions between the groups were not statistically significant. Given the small sample size, the study was likely underpowered to detect differences between conditions. Future research with larger sample sizes, a less potent control group, and clinical populations is needed to test the effects of the intervention more extensively. Nevertheless, this study demonstrates that single-session perfectionism interventions hold promise and merit future investigation.

Evaluating the Sampling Precision of Social Identity Related Published Research
Authors: Wilson Cobe , Trafimow David , Wang Tony , Wang Cong
Published: December 2022

Social identity theory states that a person’s sense of who they are is based largely on their group membership(s). We categorize ourselves, identify with groups, and compare our groups with others, in the hopes that our self-esteem is maintained or boosted from this comparison. A prerequisite of scientific research, even regarding social identity, is that researchers need to be confident that the empirical facts really are factual; that is, that the sample statistics reported accurately estimate corresponding population parameters; this is known as sampling precision, or how precisely our sample corresponds to our population. By employing the recently invented a priori procedure, the present research assesses the sampling precision with which published experimental and correlational social identity research statistics, across three time periods, estimate corresponding population parameters. We hypothesized 1: The precision of research in the social identity area should be hopefully below the 0.10 level or at least the 0.20 level for true experimental designs and 2: Precision in the social identity area should be improving, with recent social identity research enjoying a precision advantage over less recent social identity research. A sample of 75 academic papers, across 46 different journals was collected for analysis. For experimental studies, the mean precision level was 0.51 and the median precision level was 0.50 (n = 39). For correlational studies, the mean precision level was 0.24 and the median precision level was 0.20 (n = 55). The main findings are pessimistic, but with the glimmer of light that precision is improving.

Effect of natural zeolite on the shear strength of cement stabilized loess soil
Authors: Tchakalova Boriana
Published: December 2022

The present study intends to make an initial assessment of the effect of a natural zeolite addition on shear strength of cement stabilized loess soil. Unconsolidated undrained triaxial compression shear tests were performed for zeolite & cement-treated and cement-treated samples. It is found that the addition of natural zeolite does not reduce the shear strength of the cement stabilized loess. It causes only slight changes in shear strength parameters of non-compacted loess-cement. This allows the natural zeolite to be successfully used for an improvement of the durability, impermeability, sorption and retardation characteristics of the loess-cement.
Impact of the loess’ hydraulic characteristics on its degree of saturation for the purpose of radon index measurements (Northeast Bulgaria case study)
Authors: Trayanova Mila , Kunovska Bistra , Valchev Simeon
Published: December 2022

Radon gas has high mobility and is driven by advection and diffusion with the soil gas throughout connected and water-unsaturated pores and/or cracks in permeable rocks and soils. Therefore, there is a need for quantitative assessment of the saturation state, even on a daily-base in order to estimate the radon potential correctly. The more so as, the permeability is one of the key factors in the radon risk assessment. For the purpose of such investigation, a vertical profile model was elaborated for a study site in Northeast Bulgaria. On the base of pedotransfer function analyses, the hydraulic parameters describing the retention function and the hydraulic conductivity function were determined for each case study. The results show that even in a month with high amount of rainfall precipitation (13% of the total amount per year), the loess profile at certain depths remains unsaturated, regardless the difference in the hydraulic characteristics.

Authors: Vasileva Tanya , Angelov Lyubomir
Published: December 2022

The liquefaction potential of soils with a content of fine-grained fraction from 14.72 to 66.88% and unit weight from 20.1 to 22.5 kN/m3 in the vicinity of Sofia was evaluated. The assessment was carried out using the cyclic shear stress method. The analysis was performed for a seismic impact with magnitude Ms = 7.5 and at the maximum reference horizontal acceleration at the ground surface αmax(g) = 0.23 and for free field conditions without load from buildings and facilities.
Layered double hydroxides as precursors for catalysts in Claisen-Schmidt condensation
Authors: Stoylkova Tanya
Published: December 2022

MMgAlO and MAlO mixed oxides (where M = Cu, Co, Zn and Ni) were obtained by thermal decomposition of the corresponding layered double hydroxides (LDH) precursors and used as catalysts for Claisen-Schmidt condensation of 2’-hydroxyacetophenone and benzaldehyde under solvent-free conditions. The catalysts were characterized by X-ray diffraction (XRD), atomic absorption spectrometry and temperature-programmed desorption of CO2 (TPD-CO2). Gas chromatography – mass spectroscopy (GC/MS) methods were used for the identification and quantification of the product mixture. A 2’-hydroxychalcone and 2-phenyl-2,3-dihydro-4H-chromen-4-one (flavanone) were received as main products. 3-Benzyl-2-phenyl-4H-chromen-4-one (3-benzylflavone) was achieved as a new product.

Geografinės informacinės sistemos glaudžiai siejasi su erdvinio turizmo samprata. Erdvinis turizmas suvokiamas kaip alternatyvi veikla, kurios metu sisteminami aplinkos duomenys ir pateikiami skaitmeniniu būdu. Erdvinių pokyčių turizmui naudojami senieji ir dabartiniai žemėlapiai, vietovių planai, vaizdinės priemonės, objektų aprašymas, kurie sugretinimo būdu parodo analizuojamos teritorijos pokytį. Toks procesas sukuria prielaidas turistinius maršrutus perkelti į erdvinį pavidalą. Pirmiausiai atliekama pasirinktos aplinkos analizė (naudojant georeferencinius informacijos įrankius); kultūrinių objektų informacijos sisteminimas ir gryninimas; vėliau atrenkamos profesionalios fotografijos, atskleidžiančios objektų išvaizdą (gali būti naudojamos palyginimui su praeities ir dabarties estetine būkle); kuriamas bendras vaizdas, kuriame atsispindi dizainas, aprašymo stilistika, nuotraukos, tikslinga objektų lokacija.

Sukurti erdvinių pokyčių skaitmeniniai žemėlapiai traktuojami kaip nauji turizmo produktai, kurie paslaugos teikėjams gali generuoti papildomas pajamas, o turistams leidžia ne tik keliauti individualiai bei pažinti kultūrinius, gamtinius objektus, bet taip pat skatina prisijungti prie darnaus turizmo plėtros. Sukurti erdvinio turizmo produktai gali būti perkelti į išmaniuosius įrenginius, o tai leidžia paslaugos vartotojams lengvai tyrinėti ir pažinti teritorijas, vertinti teritorijoje įvykusius istorinius ir šiuolaikinius pokyčius.
UGDOMOSIOS APLINKOS ĮTAKA IKIMOKYKLINIO AMŽIAUS VAIKŲ SOCIALINĖS KOMPETENCIJOS UGDYMUI(SI)

Published: December 2022

Straipsnyje, remiantis mokslinės literatūros analize bei atlikto tyrimo duomenimis, aptariamos ikimokyklinio amžiaus vaikų socialinės kompetencijos ugdymosi galimybės, panaudojant ugdomąją aplinką. Straipsnyje nagrinėjama problema – kokią įtaką turi ugdomoji aplinka ugdant vaikų socialinę kompetenciją ikimokykliniame amžiuje. Tyrimo tikslas – atskleisti ugdomosios aplinkos įtaką ikimokyklinio amžiaus vaikų socialinės kompetencijos ugdymui(si). Tyrimo uždaviniai: teoriškai pagrįsti ugdomosios aplinkos įtaką socialinės kompetencijos ugdymui(si) ikimokykliniame amžiuje; empiriškai atskleisti tėvų požiūrį į ugdomosios aplinkos įtaką ikimokyklinio amžiaus vaikų socialinės kompetencijos ugdymui(si). Tyrimo metodai: mokslinės literatūros analizė, apklausa (raštu), statistinė duomenų analizė. Tyrimo rezultatai atskleidė: ugdomoji aplinka yra erdvė, kurioje ugdytinis gyvena nuolatos, ir kuri skatina vaiko ugdymosi pasiekimus, jo individualų tobulėjimą. Ikimokyklinio amžiaus vaikas aplinkoje ne tik susipažįsta su įvairiais daiktais ir jų funkcijomis, tačiau kartu vaikas patiria įvairių įspūdžių, įgyja naujas patirtis, tyrinėja, eksperimentuoja ir atranda. Socialinės kompetencijos ugdymo svarba ikimokykliniame amžiuje neabejotina, kadangi socialinė kompetencija lemia vaiko kaip pilnateisės ir savimi pasitikinčios asmenybės sėkmę kitose ugdymosi srityse bei tolimesniame gyvenime. Ikimokyklinio amžiaus vaikų socialinės kompetencijos ugdymo tikslas - supažindinti ugdytinius su įvairiomis vertybėmis ir visuomenei priimtinu elgesiu, kad ugdytiniai gebėtų orientuotis aplinkoje, tinkamai joje elgtis, bendrautų ir bendradarbiautų su kitais, kontroliuotų savo elgesį bei emocijas.

Straipsnyje aptariamos naujausios lietuvių kalbos leksikos sluoksnio – neologizmų – rūšys ir jų paplitimas studentų kalboje. Tyrimo tikslas – atskleisti norminių ir nenorminių neologizmų paplitimą studentų kalboje. Tyrimo uždaviniai: 1) aprašyti neologizmų rūšis kilmės ir normos požiūriu; 2) apžvelgti studentų vartojamus neologizmus normos požiūriu. Tyrimo objektas – studentų kalba. Tyrimui pasirinkta kiekybinė tyrimo strategija. Tyrimo metodai –mokslinės literatūros analizė ir sintezė, studentų apklausa raštu, tyrimo duomenų statistinė analizė. Studentų kalbos tyrimas rodo, kad jie gausiai vartoja įvairių svetimų kalbų žodžių, tačiau kartais suranda šiems svetimžodžiams lietuviškų atitikmenų ir pakaitų. Norėdami suteikti kalbai ekspresyvumo, studentai dažnai vartoja tam tikslui sukurtus naujadarus. Remiantis tyrimo duomenimis galima teigti, kad studentų kalboje lietuviški naujažodžiai visiškai nukonkuruojami skolinių, įteisintų rekomendaciniame Valstybinės lietuvių kalbos komisijos svetimžodžių atitikmenų sąraše. Naujažodžio ar neteiktinos svetimybės pasirinkimas rodo, kad  beveik pusę klausimyne pateiktų naujažodžių nukonkuruoja neteiktinos svetimybės. Lyginant pirmosios ir antrosios apklausų raštu duomenis galima teigti, kad pusė tyrime pateiktų naujažodžių gerokai populiaresni už nevartotinas svetimybes, tačiau visi tyrime pateikti lietuviški naujažodžiai vartojami dažniau negu teiktini skoliniai.
