THE INFLUENCE FF MOTIVATION, KNOWLEDGE LEARNING PROJECT STRENGTHENING PROFILE OF PANCASILA (P5) STUDENTS INDEPENDENT CURRICULUM ON INTEREST IN CULTURAL FOOD OF INDONESIAN VEGETABLE PEELS IN CLASS 1 STUDENTS OF SDN CIREUNDEU 01 TANGERANG-SELATAN
Authors: Milawati Revilia
Published: January 2024

The Influence of Motivation, Learning Knowledge of the Pancasila Profile Project (P5) Independent Curriculum on Interests in My Indonesian Culture Food Pecel in students of SDN Cireundeu 01 South Tangerang. This research was conducted to analyze the relationship between motivation, knowledge, and interest in eating Indonesian traditional food, my cultural food, namely Pecel Sayur, in grade 1 students at SDN Cireundeu 01, South Tangerang. The data collection technique in this study was by distributing questionnaires. Learning is the main activity in the educational process in schools. Learning is a conscious effort to change attitudes and behavior. In an effort to achieve changes in behavior needed motivation. Motivation is one of the factors that encourage students to want to learn. Motivation to learn can be classified into two, namely intrinsic motivation (states that originate from within the student himself which can encourage him to take learning actions) and extrinsic motivation (states that come from outside the individual student that encourage him to carry out learning activities). Whether there is motivation to learn greatly affects the success of student learning. Learning success will be achieved if there is a will and drive to learn. Learning is a process where there is positive interaction between teachers and students in an effort to achieve learning goals. The achievement of learning objectives is one of the factors that determine the success of teaching and learning. Learning is the main activity in the entire education process in schools. The success of achieving educational goals is very dependent on the effectiveness of the learning process taking place. While learning can be interpreted as a relatively fixed change in individual behavior caused by experience and involving cognitive skills and attitudes in an effort to achieve educational goals. Learning is effective if the interaction between educators and students is active and the expected goals can be achieved within a predetermined timeframe. In connection with the achievement of learning and educational goals, fostering student learning motivation is a very important task for the teacher. Learning will take place effectively if students have motivation in learning. Teachers must make maximum efforts so that students are motivated to learn. Therefore, learning motivation is one of the keys to success in achieving learning goals. Learning motivation must be aroused in students so that students are motivated in learning traditional foods so that grade 1 elementary school students' knowledge of traditional foods increases and interest in eating traditional Indonesian food Pecel sayur is high.

LEARNING MEDIA IN THE PERSPECTIVE OF THE QUR'AN AND HADITHSalahuddin Musofeeroos01@gmail.comAbstrackThe development of science and technology is increasingly encouraging renewal efforts in the use of technological results in the learning process, and it is possible that the media must be adapted to the developments and demands of the times. Because of the right media support, learning objectives can be achieved well too. Therefore, a learning media will affect whether or not the information is complete and on target, and affects the final outcome of the learning  this process. At the time of the Prophet SAW, teaching and learning activities were known, so if we look back at the time of the Prophet SAW, actually the learning media itself already existed and had been applied by Rasulullah SAW. He is in teaching science to his friends cannot be separated from the existence of the media as a means of conveying Islamic religious teachings.
ANALYSIS OF ISLAMIC RELIGIOUS EDUCATION LEARNING MANAGEMENT AND ITS IMPACT ON TEACHING METHODS IN BAN BANGPU YARING PATTANI ELEMENTARY SCHOOL, THAILAND
Authors: Niwae Yahaya
Published: January 2024

The objective of this study is to analyze Islamic religious education learning management at Ban Bangpu Yaring Pattani Public Elementary School in Thailand. Utilizing a qualitative descriptive study and a case study approach, this research focuses on the perspectives of the school principal, teachers, and students. Data were procured via interviews, observations, and document analyses, which were subsequently interpreted qualitatively using the Huberman and Miles model. Our findings show that the Islamic religious education curriculum management at Ban Bangpu Yaring Pattani Public Elementary School undergoes several stages: (1) The planning of the curriculum begins with an emphasis on the Islamic curriculum at the basic education unit level, a SWOT analysis, the establishment of a curriculum development team for Islamic religious education, curriculum development, revision based on feedback, approval by the local Department or Office of Basic Education, followed by implementation. (2) The implementation of the Islamic religious education learning lacks innovation due to a majority of the teachers being senior staff. Their limited skills in utilizing new technology result in a reliance on traditional learning management models. As a consequence, the learning process fails to fully engage students and teachers struggle to keep pace with modern teaching styles. Notwithstanding, the teachers excel in dedicating ample attention to the students. (3) The evaluation of student learning outcomes has been conducted by teachers to determine the students' mastery of basic competencies in elementary school. The assessment of student learning occurs at the end of each basic competency using predefined indicators based on the minimum competency criteria value, conducted in four stages: classroom, school, regional, and national levels. This study underscores the need for more innovative approaches in Islamic religious education and training in new teaching methods for senior teachers to better engage students and match up with the dynamics of the modern world.

SOFT METROLOGY OF TRANSMISSION HAZE: AN EXPLORATORY STUDY
Authors: Santandreu Oliver M. , Leloup F.
Published: January 2024

This study assesses optical measurement methods for the characterization of transmission haze in correlation with its visual perception. For this, seven silica-filled amorphous polymer test samples were selected from a developed sample set. Commercial haze meters and alternative measuring techniques were used to quantify the haze of the test sample set optically. Visual scales were derived using the maximum likelihood difference scaling procedure, from multiple psychophysical tests in which the test samples were presented under different assessment conditions. More specifically, the test samples were backlit through a pattern mask, with 3 different, predetermined air gap distances between the specimen and the viewed contrast pattern. From the results a clear correlation between the visual and optical haze scales is demonstrated. The best correlation seems to be obtained when samples are presented with a 4 mm air gap.
VARIATION IN PHOTOPIC AND MELANOPIC LIGHTING IN SWISS OFFICES: A FIELD STUDY
Authors: Karmann C. , Pierson C. , Wienold J. , Barthelemes V. , Andersen M. , Danell M.
Published: January 2024

Health requirements for lighting in buildings are becoming increasingly important in building standards. Yet, there is a lack of concrete data on the lighting conditions that prevail in our workplaces, in terms of their spectral characteristics, their seasonal variation, the influence of orientation or the chosen blind control strategy, and how they might impact occupants’ well-being. The objective of this study is to start addressing this gap by offering insights into the kind of lighting environments that typical Swiss open-plan offices provide to their occupants regarding non-image forming (NIF) effects of light. Towards this end, we conducted on-site continuous measurements of spectral irradiance and photopic illuminance in two open-space offices presenting some common characteristics (e.g., WWR, artificial lighting strategy, climate) and some differences (e.g., orientation, floor to ceiling height, venetian blind control system). On average, we recorded three times more light, both photopic and melanopic, in office A compared to office B. Our hypothesis to explain such a large difference is that the blinds, which were exclusively manually controlled in office B, were kept mostly closed independently of the outside conditions. Automated blinds seem like a more suitable option to optimize daylight penetration and NIF effects of light, though it must be associated with a manual override option to avoid negatively impacting the occupant’s perceived comfort.
METRICS INDICATING PROPERTIES OF LIGHT COLOUR AND SUBJECTIVE EVALUATION OF COLOUR APPEARANCE
Authors: Iwata T.
Published: January 2024

In order to identify the relationship between the metrics indicating properties of light colour and subjective evaluation of colour appearance, field measurements and subjective experiments are carried out. It was shown that there are cases where general colour rendering index (Ra) is low and the Relative Gamut Area Index (Ga) is high. For RGBLED, duv and Ga were negatively correlated, however, it was suggested that even for the same CCT and duv, Ga varies with the type of light source. The subjects' evaluation showed that light sources with greater Ga were rated higher than light sources with greater Ra, for vividness and desirability. For naturalness, the light source with greater Ra was rated higher than light source with greater Ga for both the wood pieces and the flower painting, at 14000 K. No difference in evaluations was found between the visual objects, the wood piece and the flower painting.
CHARACTERISING CIECAM02 PREDICTIONS OF PERCEIVED COLOURFULNESS AND HUE CHANGES AT DIFFERENT LIGHT LEVELS DUE TO HUNT EFFECT
Authors: Li J. , Ohno Y.
Published: January 2024

The purpose of this study is to characterise the predictive performance of the CIECAM02 and CIECAM16 colour appearance models by comparing with experimental results on Hunt Effect over a wide range of illuminance levels. In our earlier experiments, red, green, yellow, blue colour matching data under higher illumination levels (6000 lx, 1000 lx, 100 lx) were collected. In this study, another experiment was conducted to collect colour matching data on Hunt Effect at lower illumination levels (300 lx, 100 lx, and 30 lx). The chromaticity coordinates of the matches and targets from both experiments were first calculated and plotted in CAM02UCS colour space. Then the CIECAM02 and CIECAM16 predictions of the colourfulness and hue angles for matches and targets were compared across different illumination levels (30 lx to 6000 lx). Slight differences (
EFFECTS OF LIGHT ON ATTENTION OF DAYTIME WORKERS: A LABORATORY STUDY
Authors: Rolf H. , Völker S. , Udovicic L.
Published: January 2024

Besides the ability of light to influence our circadian rhythm, an impact on our acute alertness was shown. In this study, we wanted to investigate whether light can be used to support employees’ attention at work, while complying with regulations for workplace lighting. In a laboratory setting, we examined differences between three light scenes that varied in their potential to activate ipRGCs. We found that lighting with the lowest activation led to better performance in attention tasks. Furthermore, also mood and self-rated comfort were improved. The impact of light on attention should therefore be seen in a broader context than only focusing on the activation of ipRGCs. In future studies, effects on our emotional system should be explicitly investigated in order to generate a more holistic knowledge and enable the design of supportive lighting that equally considers attention and well-being at work.

Published: January 2024

Over the past two decades, there has been a significant growth of interest in participatory mapping approaches in various research fields. However, their application in studying the effects of outdoor lighting on perceived urban experiences is relatively recent and limited. This paper aims to verify the capability of the Public Participation GIS (PPGIS) to access residents' location-specific knowledge and perceptions of outdoor lighting through an initial exploration of mapped places. It focuses on perceived overall lighting quality (POLQ) and perceived brightness (PB) as attributes for comparing mapped places. Additionally, the paper discusses participants' written feedback regarding the PPGIS survey. The findings reveal notable differences between areas with higher reported POLQ and PB, compared to those with lower POLQ and PB. Furthermore, a strong positive correlation between POLQ and PB attributes was found. Participants' feedback was predominantly positive. These results highlight the potential of PPGIS in future research on outdoor lighting.
ASSESSING THE USE OF ENVIRONMENTAL LIGHTING ZONES FOR THE PROTECTION OF AQUATIC NATURE CONSERVATION AREAS
Authors: Jägerbrand A. , Brutemark A. , Andersson P.
Published: January 2024

Anthropogenic light can have adverse effects on species and ecosystems, effects that are numerous and challenging to anticipate due to their high variability and complexity. In this study our objective was to investigate the feasibility of utilising environmental lighting zones for the management of aquatic Natura 2000 conservation areas. The aim of the Natura 2000 network is to ensure the long-term survival of Europe's most valuable and threatened species and habitats. Maintaining a favourable conservation status and sustainable management of these habitats is of utmost importance, necessitating the avoidance of negative impacts of human activities, including anthropogenic light. Our preliminary findings indicate that employing a relatively high number of environmental lighting zones intervals is essential for effective implementation of mitigation measures. This approach facilitates the identification of protected areas experiencing the highest levels of light emissions, aiding in targeted conservation efforts.
A CASE STUDY OF TUNABLE WHITE LED LIGHTING WITH NETWORKED LIGHTING CONTROLS
Authors: Miller N.
Published: January 2024

Networked lighting controls hold promise for energy savings, asset tracking, simplification of maintenance, and options for setting scenes or moods in architectural and treatment spaces. Tunability of light intensity and colour may support biological health, especially in healthcare and senior living spaces. However, in the US, their complexity too frequently results in systems hard to coordinate in colour, intensity, and timing, and frustrating for staff and users to use. This paper describes a Mild Cognitive Impairment center in Atlanta, with the design, installation, and extensive rework of the control system to achieve the controls intent. The research motivation was originally to document the effect of lighting and controls on MCI patients. When it became clear the networked system was behaving unpredictably, the motivation morphed into studying what went wrong and why, and how to avoid similar problems in the future. Standardization, interoperability of components, and a common vocabulary is needed.

Authors: Pan J. , Song L. , Cao L. , Li Q.
Published: January 2024

With the rapid development of Near Eye Display (NED) technology, there is an urgent need for accurate measurement techniques to evaluate NED quality. The key to precise characterization lies in determining the reference of the optical field, namely the exit pupil, eye point, and optical axis. However, conventional methods suffer from issues such as measurement errors, complex operations, and low efficiency. We propose a new method called the layer-by-layer scanning method to determine the optical reference in optical field measurements of NED. The layer-by-layer scanning method aims to improve measurement accuracy, simplify operations, and enhance efficiency.

As a first step, the distribution functions found in the literature were examined based on our measurement results, and the suitable functions for further work were determined. Temperature and forward current-dependent models are then created with the help of polynomial regression, for the parameters established during fitting. In the field of phosphor modelling, a new aging test based on samples with a distant phosphor arrangement was launched, the details of which are discussed in the paper.
CAN INACCURATE POWER IN SPECTACLES AFFECT VISUAL ABILITY AND CAUSE EYESTRAIN WHEN WORKING NIGHTS IN AMBER LED LIGHTING?
Authors: Hemphälä H. , Lindén J. , Skjöld A.
Published: January 2024

In a pilot intervention study with integrative LED lighting (white tuneable lighting during the day and blue-free amber at night) at a hospital ward, a problem arose. Some of the night staff complained about eyestrain, and other visual problems when working in amber lighting, that might have been caused by incorrect power in their spectacles. An optometrist performed visual examinations and distributed new updated spectacles. The participants rated eyestrain, visual ability, headache and if the lighting was sufficient for their work tasks. The visual acuity and visual ability improved, and the eyestrain was reduced. The amber lighting was regarded as insufficient to perform any work tasks.
The study shows a potential problem working in amber lighting with wrong power in spectacles. Amber lighting can reduce the ability to focus and therefore it might be necessary to recommend visual examinations to ensure accurate spectacles when working in amber lighting.
LIGHTING ENVIRONMENT DURING BREAKS WHEN WORKING FROM HOME
Authors: Mochizuki E.
Published: January 2024

The purpose of this study is to examine how to control the lighting environment during breaks to reduce visual fatigue due to VDT tasks. Subjective experiment was conducted in two experimental chambers assuming a work space with constant lighting condition during the task, 500 lx of the desktop illuminance at 5000K of the CCT, combined with 6 different lighting conditions during breaks. Visual fatigue of the subjects was evaluated by three methods, ART (Accommodation Response Time) and CFF (Critical Fusion of Flicker) as objective tests and questionnaires for evaluation of subjective symptoms of fatigue as a subjective test.
The results showed that visual fatigue was reduced by lowering illuminance or by providing variable lighting in the area around the subjects’ desk during breaks. However, the subjects felt less comfort in the case with variable lighting by spotlights around the desk than in the case with constant lighting during breaks.

Published: January 2024

The sunglass industry has seen a major development in the past few years, though without the development of sunglass simulation tools for the wearers. This study describes a protocol to accurately simulate sunglass filtered vision using hyperspectral imaging and colour appearance model. The use of hyperspectral imaging ensures that the spectral transmittances of the sunglasses can be applied to the spectral radiances of the target scene. This filtered hyperspectral data can then be converted into a colour image using CIE XYZ tristimulus values and image colour appearance model (iCAM06). The study also identifies the protocol for the testing of these filtered images through psychophysical experiments and formulates the key parameters for testing. Furthermore, the study also categorizes the acquisition parameters for accurate and fast application of sunglasses on hyperspectral images. Objective testing on the optimized hyperspectral data revealed a reduction of data size by four times, without any loss of colorimetric accuracy. The study lays out a clear path for the future execution of psychophysical experiments to validate the accuracy of reproduction for these simulated images.

Authors: Slembrouck N. , Audenaert J. , Leloup F.
Published: January 2024

Hyperspectral imaging techniques offer interesting new methods of measuring visual appearance. In this paper, two different types of hyperspectral cameras (snapshot vs. linescan) are compared on a theoretical and practical basis, and it is tested if they could be used for visual appearance measurements. The cameras are first characterized and calibrated. A GretagMacbeth ColorChecker® is then used to compare and evaluate the quality of the spectral reflectance measurements of the two cameras. Whilst the data of the snapshot camera better matches the spectral measurements obtained with two spectrophotometers, the spatial performance limits the usability of the device. Based on the findings of this study, further research is discussed in order to improve the measurement accuracy of the snapshot hyperspectral camera.

Published: January 2024

Easily controlled LED luminaires with a wide range of light colours and intensities have been developed recently. Their characteristics can be adjusted to mimic that of natural daylight. However, considering that the colour and intensity of daylight vary constantly with time and weather, it is necessary to verify whether the same effect can be achieved using LED luminaires for interior lighting. Therefore, this study examined a method for reproducing the correlated colour temperature (CCT) and illuminance fluctuations of daylight using LED luminaires. Two experiments were conducted using daylight or LED luminaires as the light source, and the physiological and psychological effects on the participants were compared in both experiments to verify whether the same effect can be achieved. The results showed no significant differences between daylight and LED luminaires in terms of physiological and psychological effects.

Low-position Road lighting systems (hereafter referred to as Low-position lighting) are effective in preventing collapse of lighting poles, fall of lamps from lighting poles, and in making inspections easier. In Japan, 'Road Lighting Installation Standards, 2007' is applied to performance indicators for road lighting systems, however these assume to set up the pole-type road lighting systems (hereinafter referred to as High-position lighting systems). The low-position lighting system has not yet been introduced in earnest. The present study compared the visibility of the Low-position lighting with conventional High-position lighting and confirmed that the Low-position lighting could achieve the same level of visibility performance as conventional High-position lighting. At last, we propose tentative performance indicators targeted on Low-Position lighting and summarized specific issues for the Low-position lighting.

According to the definition, the gloss value can be obtained from reflectance measurements with the geometries specified by the standards, or by measuring the bidirectional reflectance around the specular direction. We think that both approaches would allow National Metrology Institutes (NMIs) and Designated Institutes (DIs) to provide traceability of the measurement of specular gloss without the need of using the external reference glass plate required by the standards and specified in the definition. An expression for the calculation of the gloss value according to the definition and the standards is given in this work, which allows this value to be obtained from measurements of bidirectional reflectance. Gloss measurements of four samples provided by NCS were performed with different measuring systems and procedures, including commercial instruments and alternative methods based on measuring systems developed for measuring bidirectional reflectance at NMIs and DIs. A consistency analysis of the measurements is presented.

El propósito de este artículo es contribuir al estudio de las redes sociales como espacio de divulgación de la profesión y la disciplina del Trabajo Social. A partir de análisis de contenido de los diez perfiles profesionales con más seguidores en Instagram y reconocidos dentro del fenómeno microinfluencer en la geografía española, se describen los rasgos más característicos de la identidad digital, el contenido audiovisual y las concepciones epistemológicas y éticas que se identifican y se difunden del Trabajo Social. Si bien es una tarea urgente establecer puentes y complicidades entre la comunicación y el Trabajo Social para favorecer la divulgación del área de conocimiento y la experiencia profesional, no hay que obviar los riesgos y consecuencias derivadas de estas prácticas digitales. Los modos de producción no son ajenos al contexto neoliberal y mercantil actual, donde lo social se ha convertido en espacio de negocio y, en ocasiones, los objetivos profesionales quedan más supeditados a los medios que al fin.
Classification and Engineering Analysis of Solid Propellant Missile Telemetry Data
Authors: Cervantes Noel , Moore Nathan , Carpenter Mark , Hartfield Roy
Published: January 2024

This paper describes classification methods of missiles using solid rocket motors. Two classification scenarios are described: one shows how to classify shortly after launch, and another shows how to use the “max” parameters of the trajectory for classification. The first scenario will show that, within the first 30 s of telemetry data, the missile class can be quickly and accurately determined. To extend this scenario, we will then determine how much data are necessary to classify, so classification will then be attempted in the first 10 and 20 s. The importance of the telemetry data can then be quantified by a direct calculation of the Shapley values. To analyze robustness, missing data are simulated and imputed for classification. The second scenario utilizes the max parameters of the telemetry, such as apogee, to classify the missile. This scenario is more akin to analyzing trajectories that have already been completed. Various classifications using different inputs for classification are shown. Both scenarios will utilize Fisher’s discriminant analysis and neural networks to compare performance, and the main goal is to classify missiles. Using discriminant analysis and neural networks provides high accuracy.
Three-Dimensional Plate Dynamics in the Framework of Space-Fractional Generalized Thermoelasticity: Theory and Validation
Authors: Aydinlik Soner , Kiris Ahmet , Sumelka Wojciech
Published: January 2024

This work aims to study the dynamics of 3D plates under uniform and nonuniform temperature distributions in the framework of the space-fractional generalized thermoelasticity (S-FGT) approach. The quadratic eigenvalue problem is obtained, which means that the thermoelastic damping plays a meaningful role due to the plate’s thermal energy absorption. The plate’s complex frequency spectrum and mode shapes (free ends) under two different temperature distributions are considered for different values of the fractional continua order [Formula: see text] and the length scale parameter [Formula: see text]. For the first four frequencies, the fractional modes closest to the experimental results and the classical modes are presented with the absolute differences between them. For the nonuniform temperature distribution case, the mode shape analysis is performed assuming that modulus of elasticity, thermal expansion, and specific heat parameters are functions of the temperature. The primary outcomes of the paper can be stated as follows: 1) the S-FGT approach analysis gives more reliable results than the classical (local) theory; 2) the peak point of the out-of-plane mode amplitude is shifted toward the warmed zone; 3) a mode shifting is observed for the uniform temperature distribution in contrast to the nonuniform temperature distribution; 4) the fractional order derivative and length scale parameter depend on temperature, similar to other material properties such as elastic modulus, specific heat, and coefficients of thermal expansion; 5) a decrease in the fractional order is observed, while temperature increases for the fixed length scale parameter. These novelties indicate that the S-FGT approach establishes a new model for analyzing materials under heating, and the results may be beneficial for designing thermal structures.
Origami-Wrapped Structures with Corrugated Unfolded Forms
Authors: Kreider Matthew , Arya Manan
Published: January 2024

Stowage schemes based on origami wrapping patterns are useful for the design of various deployable spacecraft structures. These origami patterns allow for the compact stowage of flat sheets of small thickness. Typically, some other structure is needed to stiffen this thin sheet when it is fully deployed and flat. This paper describes a class of thin-shell structures that can be compactly stowed using origami wrapping methods but have a corrugated form when deployed. These structures cannot reach a flat state by design. The persistent corrugations provide stiffness without the need for an external structure, thus leading to overall savings in mass and complexity. The geometrical design of the corrugations is highly tunable. This paper describes a method for generating the form of these folding structures; the method guarantees that the structure can be unstrained both when compactly wrapped and when fully deployed. Test articles are fabricated to demonstrate the concept, and stowage experiments and stiffness experiments are conducted. A structural finite element modeling procedure is described to predict the deployed stiffness of these structures, and the stiffness predictions match the experimental results.

Published: January 2024

This study measures the film cooling effectiveness along the trailing edge (TE) of a turbine blade in a linear cascade. The film cooling effectiveness is measured and analyzed using the pressure-sensitive paint (PSP) technique. Two different TE designs are investigated: the standard pressure side cutback and the new alternating discharge design (referred to as a wavy-TE design). The alternating discharge design is a new design with a wavy structure between the pressure and suction surfaces at the TE. The new wavy structure allows the coolant to discharge from the TE so that it alternates between the pressure and suction surfaces. Testing is carried out in a five-blade, linear, steady-state cascade with inlet and exit Mach numbers of 0.20 and 0.30, respectively. The freestream turbulence intensity is measured to be 10.5% upstream of the blade leading edge. Coolant-to-mainstream mass flow ratios (MFRs) vary from 0.30 to 1.25% and coolant-to-mainstream density ratios (DRs) of 1.0, 1.5, and 2.0 are examined. A positive MFR and DR effect is witnessed. The results demonstrate the potential of the alternating discharge as a promising TE design and provide gas turbine designers with an improved TE cooling scheme.

Published: January 2024

"In a number of European Union countries, there have been cases where credit institutions and their infrastructure are used for money laundering, and the Republic of Latvia is no exception. The purpose of this article is to analyse the national and international legal frameworks in the field of autonomous money laundering, paying special attention to the use of the indirect proof method for proving the involvement of credit institutions in money laundering and the customer control mechanism implemented by credit institutions. The article has an introduction, three chapters and a conclusion. The first chapter of the article examines the national and international legal framework in the field of money laundering, the second chapter analyses ‘stand-alone’ money laundering and its proof, or the importance of indirect evidence in crimes of money laundering, and the third chapter deals with the identification of money laundering in credit institutions in the Republic of Latvia. Generally recognized scientific research methods, as well as legal interpretation methods, were used in the preparation of the article. Keywords: coercive measures, indirect proof method, ‘stand-alone’."
Legal Basis of Sanctions against Russia and Asset Confiscation
Authors:   Law Firm ‘BDO Law’, Latvia, Zelmanis Jānis
Published: January 2024

"This study provides an in-depth examination of the legal bases for current asset freezes in the European Union (EU) and the United States (US), and how these differ from confiscations of Russian state assets. It explores the evolving political deliberations that have led to new goals of making reparations to Ukraine, which has suffered extensive damage estimated at more than 600 billion euros as a result of Russia’s invasion. The primary focus of this study is on the potential confiscation of frozen state assets of Russia as a means to achieve reparations. Western governments have initiated comprehensive assessments of avenues to perform permanent asset seizures, with the overarching goal of strengthening the tracing, identification, freezing and management of assets as preliminary steps for potential confiscation. The study discusses the legislative pitfalls associated with sovereign asset confiscation, its challenges and limitations. It highlights how the principle of sovereign equality of states can hinder such actions, protecting the assets of Russia’s central bank from court proceedings and execution in another state. Despite Russia’s actions contravening the fundamental norms of international law, interpretations of customary international law maintain Russia’s immunity from legal proceedings in foreign courts. Therefore, it can be concluded that there are no legal bases for the expropriation of Russian sovereign assets. Keywords: confiscation of assets, Russian assets, reparations, legal considerations, International law, sanctions, sovereign equality."
Silica nanoparticles: Chemical synthesis and acute neurotoxic study in Wistar rat

Published: January 2024

Objectives:

In this study, silica nanoparticles (SNPs) were synthesized through the sol-gel approach, characterized using X-ray diffraction and examined for their potential to induce acute neurotoxicity in rats.

Materials and Methods:

The average particle size was confirmed to be 110 ± 5 nm through scanning electron microscope (SEM) analysis. An intraperitoneal injection of 25, 50, and 100 mg/kg of SNPs was administered twice over 24 h to rats, followed by autopsies 24 h later. Brain regions (cerebellum, frontal cortex, hippocampus, and corpus striatum) were analyzed for changes in antioxidant enzyme activity (superoxide dismutase [SOD], catalase [CAT], glutathione-s-transferase [GST], glutathione peroxidase [GPx], glutathione reductase [GR] and thiobarbituric acid reactive substance [TBARS] levels) and neurotransmitter concentrations (acetylcholinestrase [AChE], dopamine, serotonin and nor-epinephrine).

Results:

The activity of SOD, CAT and GST increased significantly in the high dose group, specifically in the hippocampus and corpus striatum. No significant change in GR activity was observed in any dose group. Significant alterations were observed in neurotransmitter concentrations in hippocampus and corpus striatum in rats treated with high dose.

Conclusion:

Overall, the outcomes derived from our research suggest that SNPs lead to dose-dependent oxidative harm and neurotoxic effects in different regions of brain.
