Dye-sensitized solar cells (DSSC) mainly use organic components as an alternative way of light harvesting element to replace the traditional silicon solar cells. N atural dye alternatively is being used as sensitizers to overcome the limitation of inorganic ruthenium dye which contains heavy metal. In this study, DSSC is expected to enhance its optical properties and light absorption by implementing gold (Au) nanoparticles. Various natural and organic sources can be extracted and acted as a photosensitizer to trap solar energy. Fresh Hibiscus Rosa-Sinensis flowers are one of the good candidates to give higher light absorption in DSSC. The characteristics of the dye photosensitizer will be observed under UV-Vis-NIR Spectrophotometer. The efficiency of complete DSSC will be determined by using LIV tester. An attempt to enhance light-harvesting efficiency and hence the light to current conversion efficiency by mixing Au nanoparticles TiO₂ paste. Au nanoparticle was selected because it can act as a medium between the dye and TiO₂ to increase the electron transmission speed. The Hibiscus dye in DSSC achieved an efficiency of 0.14%. However, the efficiency reduced to 0.000178% as Au NPs was added. The effects of the addition of Au nanoparticles are discussed.

Changes in the spatial and temporal rainfall pattern affected by the climate change need to be investigated as its significant characteristics are often used for managing water resources. In this study, the impacts of climate change on rainfall variability in Johor was investigated by using General Circulation Model (GCM) on the availability of daily simulation for three representative concentration pathways (RCP) scenarios, RCP 2.6, RCP 4.5 and RCP 8.5 for interval year of Δ2030, Δ2050 and Δ2080. In addition, the annual future rainfall trend for the first interval year of Δ2030 was also made. Daily rainfall series from eight (8) stations in Johor, Malaysia capturing 30 years period (1988-2017) with less than 10% missing data were chosen. The annual mean rainfall for RCP 2.6, 4.5 and 8.5 was predicted increase by 17.5%, 18.1% and 18.3%, respectively as compared to historical data. Moreover, the Mann-Kendall (MK) test was used to detect the trend and resulted in no trend for RCP 2.6. Even so, RCP 4.5 showed a significant upward trend in Muar and Kota Tinggi, and for RCP 8.5, all regions were detected to have an upwards trend except for Pontian and Kluang. In general, the concentration of greenhouse gases from RCP 8.5 gave the highest rainfall in future.

Political Ideology, Policy Attitudes and Public Support for European Integration
Authors: Toshkov Dimiter
Published: February 2023

How does public support for European integration relate to the broader political views of European citizens? This article maps in a comprehensive way the relationships between support for European integration, left-right ideological positions and policy attitudes towards redistribution, immigration and gay rights. We introduce the use of flexible non-parametric methods (generalized additive models) and more appropriate measures of dependence (the distance correlation coefficient) to explore and measure the strength and forms of these relationships across time (2004-2020), countries and indicators of European integration support. We find that the link between public support for European integration and left-right ideology is weak. The exact form of the relationship depends on the operationalization of European integration support, the country and the time period, but it rarely resembles the classic inverted-U curve suggested by existing literature and studies of party positions. In fact, average EU support is typically highest at the moderate left rather than at the center. The relationship of support for further European integration with immigration attitudes is much stronger, stable, consistent and almost linear; with support for gay rights it is also linear but considerably weaker; with support for redistribution there is practically no relationship at all. While public opinion is much less structured and less extreme than party positions, there is some evidence that – across countries – the strength of the links between EU support, left-right and policy positions at the party level is associated with the strength of these links at the level of the public. Furthermore, over time the strength of the link of public EU support with different policy attitudes covaries systematically with the salience (media presence) of the issue at the EU level.
Sand Shoal Dynamics of a Tide-Dominated Estuarine Embayment: Comparison of a Numerical Sediment Transport Model against Field Observations
Authors: Williams Ben , Nielsen Lex , Glamore Will , Rayner Duncan , Flocard Francois , Williams David
Published: February 2023

This paper presents an innovative and detailed dataset of currents and sediment transport observations over a sand shoal system responsible for focusing wave energy on eroding coastline. The data are used to measure the performance of a detailed numerical sediment transport model of the sand shoal system. The predictive skill of the model is 0.96 for tidal elevations within Port Phillip Bay, 0.75 for tidal currents over the shoals, and 0.80 for bedload transport. Analysis of available bathymetric data suggests the sand shoal system exhibits large-scale mobility over unexpectedly short timescales, which must be driven by exceptionally strong tidal currents. Simulated residual bedload estimates are of the order of 5,000 m3/ m / annum over the crest of the bank and are highly ebb-dominant. The data and calibrated model system will be used as a tool to inform the efficacy of various coastal management options at Portsea.
The impact of age and Alzheimer’s disease on locus coeruleus mediated neuromodulation of neural circuits and goal-directed behavior
Authors: Joshi Siddhartha
Published: February 2023

Neuromodulators affect cognition and behavior via their actions on brain wide neural networks. The locus coeruleus norepinephrine (LC-NE) system is one of the brain’s major neuromodulatory systems. Aging and neurological diseases lead to changes in brain structure that impact the normal functioning of brain networks and neuromodulatory systems. Although the precise nature of this impact, its diagnosis and quantification remain a challenge, recent studies in humans and in animal models have started to reveal details about the effects of intrinsic neuromodulators on neural networks and behavior. These recent findings are beginning to suggest how systems neuroscience approaches might help develop new tests to supplement the wide range of established clinical assays for testing cognitive deficits due to aging and Alzheimer’s disease. Here, I will review what we know about networks that perform computations driving perception and action and how these networks are affected by activation of the LC-NE system. I will examine what is known about aging and Alzheimer’s disease related changes in these networks and in the LC-NE system and the resulting impact on perception and action. I will discuss the relationships between activation of this system and changes in pupil size, recently explored with precision in humans and in animal models. I will examine how, when combined with perceptual or cognitive tests, these findings provide a basis for exploring the use of pupillometry as a non-invasive assay of age- and disease-related decline in neuromodulatoryfunction.
What explains the failure to identify replicable moderators of symptom change in social anxiety disorder?
Authors: Erceg-Hurn David M , McEvoy Peter
Published: February 2023

Trials of cognitive behaviour therapy (CBT) for social anxiety disorder (SAD) have struggled to identify replicable moderators of treatment outcome. This could be due to a genuine lack of effects, or a spurious finding caused by methodological factors such as inadequate testing of theory-driven moderators, use of small homogenous samples, failure to model non-linear relationships, and over-reliance on significance testing. We probed explanations for the field’s failure to detect moderators by testing whether 15 theory-driven and atheoretical variables moderated treatment outcome in a large heterogeneous sample treated with group CBT for SAD. Moderation was not assessed by only using p-values for linear models, but also by considering effect sizes, plots, and non-linear relationships. Despite using a comprehensive approach to assess moderation, only two variables – the baseline severity of SAD symptoms and fear of negative evaluation (FNE) – were found to moderate social anxiety symptom trajectories. FNE had a non-linear relationship with symptom change that would have been missed using common research methods. Our findings suggest both a genuine lack of effects and limitations of research methods have contributed to the field’s inability to identify moderators. We provide suggestions that may increase the likelihood of future researchers detecting genuine effects.
Virtual reality exposure therapy for reducing social anxiety associated with stuttering: The role of outcome expectancy, therapeutic alliance, presence and social presence
Authors: Chard Ian , van Zalk Nejra , Picinali Lorenzo
Published: February 2023

Although several trials have demonstrated the effectiveness of Virtual Reality Exposure Therapy (VRET) for reducing social anxiety, there is little understanding about the factors that lead to symptom reduction across different treatment designs. Such factors may include outcome expectancy, therapeutic alliance, presence (perception of being in the virtual environment) and social presence (perception of interacting with others). We report on findings from a pilot trial of VRET targeting social anxiety in people who stutter, and examine the association of these four factors with treatment outcome. People who stutter reporting heightened social anxiety (n = 22) took part in the trial after being recruited via online adverts. Remotely delivered VRET was administered to participants in three sessions across three weeks. Each session targeted both performative and interactive anxiety. A virtual therapist helped participants to engage with treatment strategies, whilst also guiding them through exercises. Findings showed that presence and social presence were both negatively related to changes in fear of negative evaluation between pre- and post-treatment. However, presence, outcome expectancy and therapeutic alliance were positively related to changes in social anxiety symptoms. Furthermore, outcome expectancy and therapeutic alliance were quadratically related to fear of negative evaluation change. Nevertheless, the effect of presence on social anxiety, and the effects of presence and therapeutic alliance on fear of negative evaluation must be interpreted with caution as these were not large enough to reach sufficient statistical power. Therapeutic alliance did not mediate the relationship between outcome expectancy and treatment outcome. These findings suggest that the current VRET protocol affected social anxiety and fear of negative evaluation differently. We discuss how presence may underlie these mixed associations. We also suggest that the unexpected positive effects on social anxiety symptoms may have resulted from insufficient treatment strategies which inadvertently encouraged maladaptive learning.
Analisis Prospektif Strategi Pengelolaan Kawasan Gambut Secara Berkelanjutan Pasca Kebakaran di Kecamatan Bukit Batu Kabupaten Bengkalis

Peat areas have unique characteristics as wetlands on land but are highly flammable if there are El Nino symptoms. The peat area has a protection function and a cultivation function and this is important for the life of living things. To date in 2021, where this research was conducted, the condition of the peat area in Bukit Batu District, Bengkalis Regency is very easy to burn, this requires a sustainable peat area management strategy from the ecological, social, and economic aspects so that fires do not occur in the future. This research can be useful for stakeholders to manage peat areas in a sustainable manner by taking into account the ecological, economic, and social aspects. Repeated fires in the same location make peat even more degraded. For this reason, it is necessary to manage post-fire peat areas, so a management strategy using prospective analysis is needed. The prospective analysis is a method that can be used to find strategies that can be applied in the future. The results of the prospective analysis in this study recommend that there are three strategies that need to be applied, from the ecological aspect, namely the conservation and rehabilitation strategy, from the social aspect, namely the MPA-preneurship strategy and from the economic aspect, namely the strategy of using burned land. These three strategies can be carried out simultaneously and holistically by involving many stakeholders in peat areas.

This paper deals with linearized and normalized differential equations of relative motion of the system under the influence of magnetic force air resistance and oblateness of the earth in Nechvill's co-ordinate system. We have linearized the problem keeping in view that the length of the string connecting the two satellites is infinitesimally small in comparison to the distance of centre of mass of the system from the centre of attracting force and introduction of rotating frame of reference eliminates the product terms as usual. We have obtained a system of six orders non-autonomous, non-linear equations of motion describe the motion of one of two satellites and the motion of satellite relative to the first may easily be obtained by m1ρ1 + m2ρ2 = 0
Effect of Poverty on Students' Participation in the Class at Community Schools in Nepal
Authors: Thapa Yogendra
Published: February 2023

To analyse the effect of poverty on households towards class participation at community schools is the main objective of this study. A cross-sectional survey is conducted within two districts among five hundred thirty students adopting random sampling. Data on class participation are collected from semi structured survey questionnaires and analysed using bivariate and multivariate analysis with help of Stata 14. It is found that poverty hinders involvement in academic activities and managing learning facilities. Parents with poverty have been involved in nonacademic activities and are unable to manage the academic home environment. As a result their children were irregular and absent, and they were involved in nonacademic activities, which are more favourable for the poverty zone except for extracurricular activities. By addressing students’ diversity and local context, students living in poverty may have done better class participation.
Nepali Educational Grammar: Theory and Practice
Authors: Mandal Ramdeo
Published: February 2023

Although efforts are being made by domestic and foreign writers, it lacks standard level wise Nepali  grammar. Therefore, the main goal of it is to develop standard level wise Nepali grammar by keeping standard grammatical contents regarding level. Primary and secondary sources were used to collect data, and qualitative analysis was performed through library work, comparative method and descriptive method. In various grammar studies alphabets, letters, syllable structure, word class, gender, number, person, tense, aspect, sense, voice, negative and positive, vocabulary, sentence difference, spelling, causative verb, idioms and definitional words are included. There is no clear boundary for grammar in different levels such as lower secondary Nepali grammar. Secondary Nepali grammar and expression, compulsory Nepali for proficiency level, higher secondary Nepali grammar and expression, and graduate level (301). It seems there is uncertainty rather than uniformity during teaching-learning. Therefore, particularly Nepali grammar should be developed to get rid of such situation and to compensate its lack.

Object: The object of the article is to study the modeling of investment processes on the example of airlines.Methods: Systematic approach, the methods of scientific knowledge, induction, deduction, comparison, statistics, comparability, financial analysis, mathematical modeling, analysis and forecasting.Results: The financial risk of the considered airline project is mainly related to the prices for aircraft maintenance services, which are at low limits. The severity of the consequences of this risk is crit ical and there is a high probability of these events. From the risk analysis, it can be concluded that the most likely financial risk is the one that can suffer the most damage. Air Astana JSC needs to use the proposed risk analysis to form a judgment about the possible conse-quences and probabilities of investment project risks. Based on the research of investment processes in airlines, recom-mendations were formulated in the field of investment project evaluation.Conclusions: Based on the analysis of the investment activity of the Kazakh company, it was revealed that outdated methods of evaluating the effectiveness of investment projects are used and it was proposed to use quantitative risk analysis and break-even assessment of the airline’s investment projects for this purpose. Despite the difficulties, avia-tion financing is an opportunity for new participants to get attractive returns, provided that the asset type and timing are chosen correctly. Based on the calculations, the inefficiency of the investment activity of the proposed Kazakh airline was revealed. The proposed methodology for calculating the break-even boundaries of investment projects will help improve the efficiency of investments

Published: February 2023

This paper studies the effects of aluminium content in the composite powder on the structure of detonation gradient coatings based on NiCr-Al. Gradient coatings were obtained by detonation spraying with a gradual stepwise decrease in the barrel filling volume with an acetylene-oxygen gas mixture from 50% to 25%. The elemental and phase composition, microstructure and surface roughness of coatings based on NiCr-Al with different aluminium content of 15%, 20%, and 30% were investigated. By varying the aluminium content in the powder composition, coatings with a gradient structure were obtained. The study results showed that the phase composition of the gradient coating strongly depends on the mass fraction of Al. In the case of an aluminium content of 30% in the composition of the composite powder, the formation of aluminium oxide was detected. It is established that under the same detonation deposition modes, the formation of the gradient structure of coatings will strongly depend on the aluminium content in the NiCr-Al composition. The study results showed that the optimal composition of the powder is NiCr – 80% and Al – 20% to obtain NiCr-Al coatings with a gradient structure.

Published: February 2023

This work studies the influence of maleic anhydride grafted polypropylene (PP-g-MA) content on thermal and mechanical properties of polypropylene (PP) composites with two types of clays, differing modifier density in the interlayer space, Cloisite15A and Cloisite20A. PP/clay composites are melt blended in presence of different content of PP-g-MA from 3, 6, 9, and 12 wt.%. It is found that Cloisite15A with a high density of the modifier promotes the formation of intercalated structures, while Cloisite20A with a low density of the modifier, predominantly exfoliated nanocomposites are formed. In the first case, the structure tends to become intercalated whilst composites with Cloisite20A favor the formation of predominantly exfoliated structures. The formation of the nanocomposite is accompanied by a significant increase in thermal stability (50% weight loss is observed at temperatures of 360°C and 430°C for polypropylene and nanocomposites based on it, respectively). An analysis of the mechanical properties of nanocomposites generally indicates an increase in the elastic modulus by 15-20%, and this effect is more pronounced for exfoliated structures, the yield strength practically does not change and the elongation at break decreases noticeably.

This article discusses possible solutions to one of the problems associated with the low efficiency of existing thermal power plants. These factors are due to both the depreciation of equipment and the lack of any effective technologies for intensifying heat and mass transfer processes. The relevance of research topics is also confirmed by the fact that at the state level it is proposed to legally oblige the subjects of the heat and power industry to carry out preventive measures aimed at optimizing existing enterprises. The description of the reasons for the occurrence of scale deposits that appear in the in-line cavities is given. Due to the fact that the thermal conductivity of solid deposits is much less than the thermal conductivity of the metals from which the heat exchanger tubes are made, they significantly reduce the intensity of the processes and the intensity of heat transfer. Solid deposits lead to a decrease in the coolant flow rate, an increase in fuel consumption and a violation of the technological mode of operation of the entire heat exchange unit. The authors analyzed various technological aspects of various methods for cleaning heat exchanger tubes from solid scale deposits, on the basis of which the advantages of the electrohydraulic treatment method are substantiated. A schematic diagram of the device is given and a brief description of the method of cleaning the pipes of heat exchangers from solid scale deposits is given using electro-hydro-pulse action. The results of the application of this technology for cleaning heat exchange pipes at specific heat and power enterprises are shown, which confirm its advantages over other cleaning methods, both in terms of processing time and energy costs. The influence of the degree of purification of heat exchange pipes from solid deposits on the thermophysical parameters and efficiency of the heat exchanger is considered.

For the first time, the authors proposed the use of the mathematical apparatus of non-standard analysis to solve certain non-trivial problems of theoretical electrical engineering. It was established that the axiomatics of non-standard analysis allows to simplify the analysis of transient processes in high-order electric circuits when the switching laws are violated. It is shown that the application of non-standard analysis methods in theoretical electrical engineering provides an opportunity to use the traditional classical method of transient processes analysis of circuits with violation of switching laws. Only by using methods of non-standard analysis, it is possible to strictly prove the fulfillment of the law of energy conservation in such schemes. Also, examples of solving such tasks are given. It is recommended to expand the scope of application of non-standard methods of analysis in problems of various branches of science and technology, which use differential calculus and boundary transitions, and the solution of which is limited or impossible by standard approaches.

Published: February 2023

The effect of silver plasmonic nanoparticles on triplet-singlet energy transfer in the donor-acceptor pair of organic dyes was studied. Layered dye films were prepared on the surface of glass and island silver films using the Langmuir-Blodgett method. Amphiphilic analogs of Rose bengal and polymethine dye were used as donor and acceptor of energy. A polymer monolayer was deposited between monolayers of donor and acceptor molecules to exclude the competing triplet-triplet energy transfer. The spectra of delayed fluorescence and phosphorescence of donor-acceptor films and the delayed luminescence lifetime of donor in these films have been measured. It is shown that a threefold increase in the fluorescence intensity and a twofold increase in the donor phosphorescence intensity are observed on silver island films. The successful triplet-singlet energy transfer is evidenced by both the quenching of donor centers and appearance of sensitized delayed fluorescence of the acceptor with the duration close to the donor triplet lifetime. In the presence of silver nanoparticles, in addition to enhancement in the intensity of the donor emission, an increase in the efficiency of tripletsinglet energy transfer was observed. The obtained results can be used in various optical devices.
