This research analyzes a violation of airspace sovereignty by unmanned free balloons for espionage purposes. Each country has full and exclusive sovereignty over its entire territory which includes the surface of the earth and the contents of the earth beneath the surface, including air space. A country that violates sovereignty over airspace without permission entails responsibility for the passing country towards the lower country. The research method used is normative juridical using problem approaches such as the statute approach, conceptual approach, and case approach. The research findings show that unmanned free balloons are the same as the classification of aircraft regulated in Annex 2 of the 1944 Chicago Convention regarding unmanned free balloons which are defined as unpowered, unmanned, and lighter than air aircraft in air flight. The use of unmanned free balloons for espionage purposes in peacetime has no legal regulations, so that they have implications for violations of state sovereignty which give rise to state responsibility. ICAO or International Civil Aviation Organization needs to reconstruct the legal ground towards unmanned free balloons usage outside the function of meteorological purposes in order to avoid the false accused and declare specified sanctions towards the violators.

Published: January 2025

Investigation of zinc and copper deterioration after 10-year exposure in different environmental sites (rural, marine, industrial) of Lithuania has been com­pleted. Different survival of mycobial communities on corroded zinc and copper at the end of ten-year experiment has been identified. Morphological and structural changes of the surface were evaluated using optical, scanning electron, X-ray diffraction microscopy and wavelength dispersive X-ray fluorescence spectroscopy. The atmospheric corrosion level was determined using the weight loss method. The lowest destruction level of copper samples exposed to industrial environment has been established. Zinc samples indicated the crystalline phases of the zinc base, Zn4CO3(OH)6 · H2O, ZnSO4 · 3Zn(OH)2 and Zn5(OH)8Cl2 · H2O. The presence of ZnO and Zn5(CO3)2(OH)6 in some sites was detected. Copper samples contained Cu2O and the crystalline copper phases. In some sites (Cu, Zn)2Cl(OH)3, Cu2Cl(OH)3, Cu4(SO4)2(OH)6 and traces of disordered Na(Si3Al)O8 were detected.

Published: January 2025

The initial stages of Cu deposition onto unmodified and modified GC electrodes with selenium compounds were investigated in a 0.5 M H2SO4 + 0.01 M CuSO4 solution over a wide range of potentials, covering both underpotential and overpotential regions. The electrochemical techniques, such as cyclic voltammetry and chronoamperometry along with structural investigation like scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and ex situ atomic force microscopy (AFM), were applied to study the nucleation and growth of Cu onto a GC electrode. On the basis of analysis of the potentiostatic current transients, it has been shown that in the potential region where Cu underpotential deposition (UPD) onto a foreign substrate is usually observed, the initial stages of Cu electrocrystallization onto the GC electrode modified with selenium compounds quite well fit the instantaneous 2D nucleation and growth model developed by Bewick et al. In the overpotential region (OPD) Cu deposition was shown to proceed by the instantaneous 3D nucleation and diffusion-controlled growth model developed by Scharifker and Hills on both the unmodified and modified with selenium compounds GC electrodes. Meanwhile, in the OPD region two successive peaked segments with the characteristic current maxima (M1 and M2) in the transients for Cu deposition onto the Se-modified GC electrode indicating some complex nucleation and growth process were determined. Some morphologic characteristics have been discussed.

Published: January 2025

2-(Methylthio)quinazoline-4(3H)-thione was synthesized by the reaction of the corresponding 4-oxo quinazoline with Lawesson’s reagent (LR). 2-(Methylthio-4-thioxoquinazolin-3-yl)acetate was obtained in a similar way, while (4-oxoquinazolin-3-yl)ketones reacted with LR to give a mixture of thionation products – (4-thioxoquinazolin-3-yl)ketones and [1,3]thiazolo[2,3-b]quinazoline-5-thiones. Alkylation of 2-(methylthio)quinazoline-4(3H)-thione with chloroacetone, ω-bromoacetophenone or ethyl bromoactate gave the corresponding 4-S-substituted derivatives, which in the reaction with hydrazine hydrate afforded 2-methylthio-4-hydrazinoquinazoline. Methyl (2-methylthio-4-thioxoquinazolin-3(4H)-yl)acetate with hydrazine hydrate under appropriate conditions underwent the heterocyclization reaction to form the 6-methylthio-2H-[1,2,4]triazino[4,3-c]quinazoline system.

Published: January 2025

The aim of the present study was to develop the deposition process of cerium compound doped phosphate–permanganate conversion coating on the carbon steel surface and to evaluate its protective and self-healing capacities. The SEM and XPS techniques were applied to characterize the structure and composition of the investigated coatings. Voltammetric measurements were carried out to determine the protective ability of the passive layer, while EIS studies yielded information on the self-healing properties of different protective systems affected by introduced artificial defects. The phosphate–permanganate conversion coating on carbon steel was chosen as the base for deposition of cerium films from the Ce(NO3)3 solution without and with SO42– ions. The presence of permanganate in the phosphating solution and incorporation of Ce into the phosphate–permanganate layer on the steel surface increase the protective ability of the conversion coating. It was stated that the low frequency impedance has the same value as before the scratch formation. This suggests that the presence of Ce in the phosphate–permanganate coating leads to high values of low frequency impedance due to the healing of defects. These coatings provide corrosion protection for carbon steel and can be candidates for development of environmentally friendly pretreatments.

Published: January 2025

A method of macro-porous silicon formation is proposed, which is based on silicon cathodic polarization in molten calcium chloride. It is assumed that the porosity formation is due to interaction of electrochemically reduced calcium metal with the silicon substrate. Surface architectures were composed of the pores up to 10 micrometers in thickness. High photoactivity of the samples was determined by photoelectrochemical measurements using white light and ethyl viologen as an electroactive agent. The proposed method offers new opportunities for silicon surface technologies, for instance, preparation of efficient electrodes for batteries and photoelectrochemical hydrogen generation as well as the platforms for sensors and antireflection coatings for photodevices.
The influence of Vietnam and Sri Lanka spinel mineral chemical elements on colour
Authors: Kleišmantas Arūnas , Daukšytė Aistė
Published: January 2025

The chemical composition of 42 various colour spinel minerals from the Vietnam Luc Yan locality and the Sri Lanka Ratnapura locality were investigated and according to the results of the research the chromophore influence on colour was interpreted. It was established that the colour of spinel mineral is determined not only by chromium, iron, cobalt but also by vanadium. We assume that V3+ determines the brown or yellow spinel colour, since a relatively high content of V2O3 (0.44–0.88%), which may determine the orangey hue of mineral, was found in the investigated orangey pink samples from the Ratnapura locality. Other chromophores found in these samples, such as chrome oxide (0.05–0.36%), iron oxide (0.08–0.28%) and cobalt oxide (0.05–0.20%), show low or medium contents, which determined the pink hue of spinel. After carrying out the research on the samples of dark red spinel, it was established that the red colour is determined by a high content of Cr3+. The purple/violet colour of samples is determined by Fe2+ and a low content of Co2+, whereas the pink hue of samples is determined by Cr3+ and a high content of Fe2+, which saturation depends on the quantitative ratio of Fe2+ and Cr3+. Relatively low contents of chromophores V3+, Cr3+, Fe2+ and Co2+ were found in the pinkish grey spinel, thus their hue is grey.

Today, it is difficult to imagine global politics without the ideas and guidelines of the concept of sustainable development, which implies an urgent and inevitable need for a comprehensive solution to existing economic, environmental, and social challenges, which will become the only opportunity to protect the interests of future generations. Ukraine, whose political development vector is aimed at integration into the European Union (EU), has additionally faced many challenges associated with the full-scale war against it by Russia and economic and political instability. In this regard, the implementation of the principles of sustainable development is a complex but vital process that requires a thorough study of the best European practices and effective benchmarks that will contribute to overall progress. Accordingly, this monograph is devoted to studying the main problems and ways to introduce the values of sustainable development of the European Union in Ukraine at the level of companies, communities, and the country.
The first section of this work analyzes sustainability strategies in EU practice as a benchmark for the Ukrainian integration process, which allows for the identification of existing problems and prospects of the integration process in Ukraine, in particular in the context of introducing EU sustainable development values in Ukraine; to suggest potential ways of integrating the principles and values of European sustainable development into the Ukrainian context. The second section presents the best sustainable market practices, mainly through the measurement of corporate social responsibility of business, the introduction and regulation of benchmarks in responsible investment markets, and the example of marketing and labeling. The third section considers innovation benchmarks for advancing sectoral sustainability, in particular regarding the systematic provision of management of innovative development of an enterprise in the focus of sustainable development values and bioeconomy, ensuring the sustainability of the agricultural sector, capitalization of financial agents in the financial services market in Ukraine in the context of sustainable development and sustainability indices of leading European stock exchanges. As a result, this work allows us to disseminate the EU's experience in sustainable development and the values of the sustainable development goals, which will be useful among academic, business, and government circles in Ukraine.

An Approach for Hybridizing N-Subalgebra with Quantified Neutrosophic Set using G-Algebra
Authors: Khalid Neha Andaleeb , Saeed Muhammad
Published: January 2025

Neutrosophic sets are a generalized form of fuzzy sets as well as intuitionistic fuzzy sets, as they address the uncertainty factor as an independent component along with truthfulness and falsity. However, traditional neutrosophic approaches often struggle with effectively managing and quantifying indeterminate elements in complex algebraic structures. To address this limitation, this paper employs an expanded version of the neutrosophic set, incorporating a subalgebra. The proposed research is multifaceted: firstly, the new concept of N-Subalgebra (NSU) is proposed. This is the modified setting in the family of subalgebras whose proposed name is the representation of the author's initial name. Secondly, the hybridization is called Quantified Neutrosophic N-Subalgebra.

Effets de la Consommation de l’Énergie sur LES Émissions de CO2 : une Évidence dans les Pays de L’UEMOA
Authors: BALOGAN Komlan Anani-Adjeoda
Published: January 2025

Mots-clés : consommation dans les transports, EKC, panel, PMG, UEMOA
Résumé
Dans cette étude, nous évaluons l'effet de la consommation de l'énergie sur les émissions de
dioxyde de carbone (CO2) dans les pays de l’Union Économique et Monétaire Ouest-Africaine
(UEMOA) au cours de la période 1990-2015. Elle tente également de valider l'hypothèse de la
courbe de Kuznets environnementale (EKC). En utilisant les méthodes de cointégration de
Pedroni et de Kao sur les données de panel, nos résultats suggèrent une relation de cointégration
entre la consommation de l'énergie et les émissions de CO2 dans les pays de l’UELOA.
L'estimation par les PMG à long terme suggère que : la croissance économique joue un rôle
important dans la contribution aux émissions de CO2. Aussi, nous constatons que l'hypothèse
d'EKC en forme de U inversé est validée pour les pays de l’UEMOA. Comme option politique,
le contrôle de la consommation d'énergie dans le secteur des transports peut entraîner une
réduction significative des émissions de CO2. Alternativement, nous suggérons aux décideurs
politiques de mettre davantage l'accent sur un système de transport efficace sur le plan
énergétique et sur des politiques visant à minimiser la consommation de combustibles fossiles.
Ainsi, la qualité de l'environnement peut être améliorée avec un impact moins délétère sur la
croissance économique

Non-Communicable Diseases (NCDs) have become an increasingly significant public health issue annually, emerging as a leading cause of mortality worldwide. Diabetes mellitus is prevalent among the population, often accompanied by comorbidities such as hypertension. Hypertension frequently manifests without symptoms, leading affected individuals unaware of their condition. Data processing is essential to transform hypertension cases due to diabetes mellitus into comprehensible information. Mapping the distribution of hypertension cases using Quantum GIS (Q-GIS) is one method to achieve this. This study aims to map the distribution of hypertension cases using the Q-GIS application in 2022 in Cipaku District, Ciamis Regency, based on village or sub-district, age, and gender.This study employs a descriptive quantitative research design. The instruments utilized include Geographic Information Systems, observation sheets, hardware, software, and digital maps. Data analysis involves univariate analysis, with a simple random sampling technique applied. Preliminary research conducted in January by the Ciamis District Health Office identified Cipaku District as having the highest number of hypertension cases in Ciamis Regency in 2022, totaling 5,528 cases of hypertension.
