Authors: Suyudi Aria , Budi Henry Soelistyo 
Published: December 2023

<p class="GLR-Abstract">A decade after the enactment of Law Number 24 Year 2009 on the Flag, Language and Coat of Arms and Anthem which introduces mandatory use of Indonesian language in memorandums of understanding or agreements involving state institutions, government agencies, Indonesian private institutions or Indonesian citizens, there are still many questions arised about the extent of which these norms should apply in the private commercial sphere. Various litigations filed before the court to declare the agreement null and void for failure to meet the language provisions. While some lawsuit has been successful, but more recent court decisions have been consistently rejecting petition to declare an agreement as null and void for failure to comply with article 31 Law Number 24 Year 2009.</p><p class="GLR-Abstract">This paper will conduct a normative study to determine the extent of which the mandatory use of the Indonesian language in the agreement has affect the private commercial sphere. In what instance violation of the provision has been fully regarded as violation of an Objective Condition for a valid agreement as regulated in Article 1320 of the Civil Code which makes the agreement null and void by law and what does not.</p>This paper will study the laws and regulations related to the mandatory use of the Indonesian language in private commercial contracts to find out about situation and study its implementation in selected court decisions to understand the situation and provide possible recommendation for improvements

Proposta de uma ferramenta computacional para traçar cartas solares e dimensionar dispositivos para sombreamento
Authors: Fernandes Leandro Carlos 
Published: December 2023

Conhecer ferramentas para estimar os percursos do Sol na abóbada celeste é de grande utilidade para projetistas de edificações. Atualmente, vários programas oferecem soluções contemplando a geometria solar. No entanto, parte desses programas exige licenças caras, enquanto algumas das soluções gratuitas apresentam fragilidades, como: gráficos com baixa resolução; apenas uma opção de sistema de projeção; código fechado; dificuldades para realizar adição de funções e para fazer frente às atualizações dos sistemas operacionais. Em relação a esses problemas, ferramentas em planilhas eletrônicas apresentam vantagens: muitos profissionais são familiarizados com as planilhas; os editores permitem salvar arquivos antigos em formatos recentes; o acréscimo de módulos ou funções é facilitado. Diante do exposto, a pesquisa aqui relatada teve o objetivo de desenvolver em planilha eletrônica uma ferramenta para traçar cartas solares e dimensionar dispositivos para sombreamento. Foi utilizado um método híbrido para o desenvolvimento da ferramenta, com características do método cascata (por haver uma ideia prévia da ferramenta e das etapas para a sua produção) e do método prototipagem (por envolver testes de protótipos). O desenvolvimento envolveu etapas como: identificação dos elementos a serem representados; escolha dos sistemas projetivos; cálculo das posições aparentes do sol e das respectivas coordenadas; representação das seções horizontal e vertical de uma abertura; e implementação dos controladores dos elementos gráficos. Os resultados mostraram que, em um arquivo leve e com uma interface amigável é possível plotar a carta solar, alternar rapidamente entre diferentes métodos de projeção e adicionar módulos para o dimensionamento de dispositivos para sombreamento.

Published: December 2023

O presente artigo resulta da minha pesquisa de Mestrado, ainda em processo de realização, na Faculdade de Formação de Professores da Universidade do Estado do Rio de Janeiro. Meu objetivo consiste em dar visibilidade, de maneira preliminar e parcial, visto que a pesquisa está em andamento, à produção cotidiana de um habitus precário – que se manifesta em disposições sociais para pensar, sentir e agir precarizadas diante da sociedade e da escola capitalista – de um grupo definido de crianças e adolescentes do lixão de Jardim Gramacho. Parto do pressuposto que as desigualdades escolares estão relacionadas com a estrutura das relações de classe, com defendia Pierre Bourdieu. Tais desigualdades são acentuadas pelo capitalismo periférico brasileiro, dando origem a uma “ralé estrutural”, conforme defendido por Jessé Souza, cujo habitus específico não atende às demandas da rotina escolar.

Published: December 2023

The paper presents the results of a study of the possibilities of using hydroabrasive cutting to produce standard samples for testing carbon-carbon materials for bending, stretching, compression, etc., to determine ultimate and long-term strength. It is known that the selective ability of the jet (compacted hydroabrasive flow) to flow around obstacles leads to a deviation of the trajectory of its movement, and, as a result, a change in the predicted shape of the cutting groove. For carbon-carbon materials, the problem becomes more acute, since the alternation of high-strength carbon fiber bundles with a softer pyrocarbon phase and a certain hollowness of the structure create conditions for active flow dissipation and blurring of the cross section behind the zone of direct hydroabrasive influence. Another problem is the effect on the properties of the residual moisture that is stored between the fibers.
It is shown that the rational conditions of water-abrasive cutting and the use of tools to compensate for the jet trajectory distortion allow limiting the zone of destruction to 0.5...0.8 mm and ensuring almost complete removal of moisture from the samples within 60 minutes. Based on the width of the destruction zone, it is proposed to introduce the coefficient of the plane of the active section of the sample, which considers these features of the process.
The impact of demographic changes in Poland on the development of the aesthetic medicine market
Authors: Tomaszewski Mateusz 
Published: December 2023

The phenomenon of an "aging Polish society" is a multi‑faceted problem which includes, among others, an increase in average life expectancy, an increased proportion of older people in the population, as well as migration to large cities. These changes, which have been taking place for many years, have impacted the development of the aesthetic medicine market. Through analyzing the general population demographics against the demographics of the aesthetic medicine market, we believe that in the coming years there will be an increased demand for aesthetic treatments in people over 50 years of age, especially in offices located in large urban centers.

Authors: Lovshenko F. G. , Lozikov I. A. 
Published: December 2023

The paper presents the results of a study of the influence of technological factors of open melting on the structure and properties of modified heat‑resistant chrome bronzes. The role of protective atmospheres and deoxidizers in the formation of the chemical composition of alloys is studied and their optimal combination is proposed, consisting in a combination of Cryolite and argon to protect the copper melt during alloying with its preliminary deoxidation with a modifier based on the composition “Cu – 10 % B”, developed and produced at a pilot production facility at the Belarusian‑Russian University. An idea of the kinetics of the dissolution process of a mechanically fused modifying ligature with a high content of an alloying component and its effect on the formation of the structure of cast materials is obtained. The optimal duration of the doping time and the base temperature, depending on the size of chromium inclusions and the state of the surface of its particles, are determined. The phase composition and physico‑mechanical properties of experimental bronzes have been studied.It has been established that the use of a mechanically fused modifying ligature with a high content of alloying component having chromium particles close to micro‑/nanodisperse size with a non‑oxidized surface and a highly effective deoxidizer modifier reduces the temperature and duration of melting, obtaining alloys with a microcrystalline type of structure (2–5 microns) and a complex of physico‑mechanical properties not inferior to, and in terms of heat resistance superior analogues, which is confirmed by the data of production tests at JSC “Belcard” (Grodno, RB) of contact spot welding electrodes made of experimental bronzes, which are 3.8 times more resistant than those used by the plant.

Abstract
Urbanization and land cover change are significantly affecting the availability of habitats for wildlife worldwide. However, linking species persistence to large-scale habitat changes is challenging, especially when wildlife monitoring data is lacking. In China, the Eurasian otter (Lutra lutra) is a species of conservation concern and is listed as endangered as a consequence of declining populations across the country. Hong Kong is home to a small population of Eurasian otters, which are primarily restricted to a set of wetlands in the inner Deep Bay area. However, the drivers of their historical distribution changes are largely unknown. We combined otter spraint data from 2018-2019 with historical records of otter data spanning 1959-2018 to examine otter habitat preference and changes in their distribution, relating this with land cover changes measured by Landsat-5 and Landsat-8 satellite remote sensing in the past (1986 and 1995) and present (2018) using supervised random forest classification. We found that otters showed habitat preference for fish ponds and watercourses, and persisted in areas where fish pond area was more readily available. We also found no significant effect of the extent of land cover changes on otter persistence, suggesting that the species is resilient to some level of fish pond loss and find value in available terrestrial habitats. Our results demonstrate the utility of relating satellite remote sensing data to species distribution data over decadal time scales and highlight the importance of managing terrestrial and wetland habitats for otters and other key species in increasingly urbanized landscapes.
Selection of tool-hole size and development of cranial implants for Ti Gr.2 perforated sheet during the flexible die-less forming process

Published: December 2023

Abstract

Single Point Incremental Forming (SPIF) is a versatile and flexible technology for manufacturing sheet metal components in small series. However, SPIF in the biomedical field can be difficult because there are many challenges. One of the main issues is controlling the settings of the process and making sure the components meet the required size standards for production. The primary goal of this study is to determine the impact of various process parameters on the formability of perforated Titanium Grade 2. The geometrical parameters, such as tool and hole diameters, were initially investigated for the formability of sheet material. Later, SPIF parameters such as toolpath, feed, and step depth were varied at three levels, and the part responses were recorded in terms of roughness, maximum temperature, and accuracy. The results reveal that the hole diameter is a significant factor for formability and the highest temperature attained during the process. It is found that surface roughness begins to decrease as the tool diameter increases for the perforated sheet. In addition, the cranial implants were prepared at specific tool-hole diameters combinations, and all sound parts were evaluated for roughness, thickness deviation, and accuracy. The cranial implant, formed with follow periphery, feed rate of 300 mm/min, and a step depth of 0.2 mm, results in both improved forming accuracy and a reduction in surface roughness. The variation in microstructure and hardness for base and optimally formed sample were also investigated.
A Dark Energy Paradigm: IV. A Cause of the Baryon Asymmetry to Predict Quark Masses as Evidence
Authors: Moon Yong-Jae , Koh Wook 
Published: December 2023

Abstract
Previously, no theory could explain what causes the baryon asymmetry and where the quark masses come from. In this paper, we propose that a cause of the baryon asymmetry can be explained in the dark energy paradigm a unified dark sector that is based on Planck’s dimensional analysis, ΛCDM , energy conservation, and force equilibrium to predict quark masses as evidence. We find that the quark confinement can be described by the Cornell potential. We find that the baryon asymmetry can be caused by “quark confinement with antiparticle conversion”. Finally, we find that quark masses can be predicted in the unified dark sector, which agree with the observed data with 1% differences (or within error ranges).

Abstract
Discarded cigarette butts (CBs) may leach toxic elements and can contaminate different environments. Here, the concentration levels of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in CBs leachates were determined, and the release rate of these pollutants from three types CBs including smoked CBs with and without tobacco (SCBs and SFs) and unsmoked filters (USFs) was examined. The mean levels of PCBs were < LOD-1.36, <LOD-1.02 and < LOD − 0.86 µg/L in SCBs, SFs, and USFs leachates, respectively. The concentrations of OCPs in SCBs and SFs leachates were < LOD-0.14 and < LOD-0.10 µg/L, respectively. The toxicity equivalent (TEQ) of the dioxin-like PCBs from the CBs leachate samples ranged from 2×10− 6-1×10− 4 ng/L. Despite the very low TEQs values in CBs leachates, continuous discharge and the toxicities of the PCBs in the aquatic environments could have unfavorably impacts on the the water boddies and/or human health. Regarding the globally great number of littered CBs and their chemical contents there should be a special facilitator attention on this global problem.

Abstract
Pancreatic cancer is one of the most malignant tumor types characterized by high metastasis ability and low survival rate. As a chromatin-binding protein, HMGA2 is widely overexpressed and considered an oncogene with various undefined regulatory mechanisms. Herein, we demonstrated that HMGA2 is highly expressed in pancreatic cancer tissues and promotes tumor malignancy through cell proliferation, metastasis, and xenograft tumor growth in vivo. Moreover, HMGA2 enhanced the cellular redox status by inhibiting reactive oxygen species and promoting glutathione. Importantly, significantly ameliorated ferroptotic cell death was observed in cells overexpressing HMGA2. Conversely, HMGA2 deletion exacerbated ferroptosis. Mechanistically, HMGA2 activated GPX4 expression through regulation at transcription and translation levels. HMGA2 promoted cis-element modification in the promoter region of the GPX4 gene by enhancing enhancer activity through increased H3K4 methylation and H3K27 acetylation. Furthermore, HMGA2 stimulated GPX4 protein synthesis via the mTORC1-4EBP1 and -S6K signaling axis. The overexpression of HMGA2 alleviated the decreased GPX4 protein level resulting from the pharmacologic inhibition of mTORC1. Conversely, HMGA2 deletion more pronouncedly reduced the phosphorylation of 4EBP1 and S6K compared to the control. A strong positive correlation between HMGA2 and GPX4 expression was confirmed using immunohistochemistry staining. We also demonstrated that HMGA2 mitigated the sensitivity of cancer cells to combination treatment with a ferroptosis inducer and mTORC1 inhibition or gemcitabine. In summary, our results revealed a regulatory mechanism by which HMGA2 coordinates GPX4 expression and underscores the potential value of targeting HMGA2 in cancer treatment.
