Published: December 2024

Abstract
The paper presents a new dry-dock method for assessing the deformation of submarine hulls using TLS point cloud data and the point cloud spatial expansion method (PCSE). The advantage of the proposed approach is the high-resolution deformation analysis that can be conducted in the case of both the availability and a lack of technical documentation on the submarine hull. The geometry assessment involves two-plane hull symmetry in longitudinal sections of a tested Kobben-class submarine located in Gdynia, Poland. The features of PCSE introduce additional geometrical parameters that are not available in the original point cloud method. The procedure for local fitting of a plane into the expansion eliminates the problem of varying densities of the hull point cloud. Accuracies of several millimetres are achieved and are applicable to multi-temporal monitoring of the deformations of submarine hulls. The assessment of similar deformations is not possible in the original point cloud method, due to the unknown parameters of the orientation and curvature of the convex cylindrical hull surface. The PCSE-based parameterisation presented here enables the creation of alternative quasi-planar point cloud projections to extract new spatial information on the object. The results of this study were verified using theoretical values derived from design data on the Kobben-class submarine, and demonstrated the effectiveness of our method in terms of detecting deformations even without design references. The proposed methodology is uniform, and can be adapted to other symmetrical structures.

This study looks at how behavioral biases affect investment choices and market efficiency. This research was conducted because many millennials invest on a bandwagon without having a good understanding of investment. This kind of study use the structural equation modeling analysis method. The study's findings indicate that the bias variable overconfidence behavior can strongly influence perceived market efficiency. Nevertheless, choices about investments are unaffected by the overconfidence bias, representational bias, anchoring, and availability behavior. The variable investment decision significantly influences perceived market efficiency. Investors with investment experience above five years and a high income can make a difference in investment decisions chosen by investors. This study theme's practical application relates to the findings of overconfidence bias, which has a substantial detrimental impact on investors' perceptions of market efficiency. A high degree of confidence among investors can lead to illogical judgments and disregarding all dangers, resulting in inefficient market circumstances.

Hajat lembur: a disaster literacy on ritual communication on the Lembang fault
Authors: Rosfiantika Evi , Aunillah Rinda , Gustaman Budi 
Published: December 2024

The Hajat Lembur is a yearly ritual by Batu Lonceng Villagers, in West Bandung-Indonesia, following the 1956 landslide disaster that occurred in the Lembang Fault area. A series of local wisdom emerged as important messages tucked into the procession that are related to the ritual communication concept. Based on the three interrelated terms of ritual communication: communication, communion, and commonality (Couldry,2003), this research seeks to reveal the meaning of the Hajat Lembur tradition as disaster risk reduction literacy. This research uses a case study approach, conducted by participatory observation in the Hajat Lembur ritual procession in 2023; in-depth interviews with two informants, in the form of opinion leaders who play a central role in the ritual procession; and literature reviews. The results showed that in terms of communication, the Hajat Lembur tradition is interpreted as a transcendent medium about the importance of maintaining harmonisation between humans, nature, and the Creator. In terms of communion, it is a celebration of the sacred Batu Wahyu that led to an agreement to establish a sacred forest, as an area that must be preserved. In terms of commonality, this ritual is a joint expression of the Batu Lonceng Village community about the importance of protecting nature and the environment inherited by the ancestors. Although there is a need for more established local knowledge in this area, this research contributes to the future of disaster mitigation management by emphasising rationality and local wisdom in dealing with natural disasters.

This study examines the function of da'wah communication in disseminating knowledge, education, and counsel to mitigate divorce rates in Central Aceh Regency. This study incorporated A descriptive qualitative methodology, specifically observation, interviews, and document analysis of pertinent literature, legislation, regulations, and scholarly publications . This methodology provided comprehensive insights into the intricate dynamics of da'wah communication and its influence on marital stability. The study investigated three principal questions: What impact does da'wah communication as an information provider have on divorce rates? How does its educational role affect marital stability? How does its advisory role aid in decreasing divorce rates in the Central Aceh District? The results demonstrate that da'wah communication significantly lowers the divorce rate in Central Aceh District by functioning as a source of knowledge, education, and guidance; effectively resolving family disagreements is essential for fostering patience and encouraging spouses to uphold marital integrity under divine guidance. In contrast, families who do not engage in da'wah communication are more susceptible to issues, misunderstanding, and divorce. These findings underscore the need to incorporate da'wah communication into community initiatives to mitigate divorce rates and promote healthier family relations. Future studies may investigate the enduring impacts of da'wah communication on marital stability and its possible implementation in many cultural settings.

Предложен новый способ дериватизации спиртов для их анализа методом масс-спектрометрии с матрично-активированной (МАЛДИ) и поверхностно-активированной лазерной десорбцией/ионизацией (ПАЛДИ). Подход основан на силилировании аналитов бромметилхлордиметилсиланом в присутствии амина с образованием соединений с ковалентно-связанным зарядом. На примере серии алифатических, терпеноидных и стероидных спиртов показано, что дериватизация протекает количественно, а регистрируемые в условиях МАЛДИ и ПАЛДИ масс-спектры содержат интенсивные пики ионов, соответствующие катионным частям получаемых производных.
A new method of derivatization of alcohols for their analysis by matrix-assisted laser desorption/ionization (MALDI) and surface-assisted laser desorption/ionization (SALDI) is proposed. The approach is based on the silylation of the analytes by bromomethylchlorodimethylsilane in the presence of tertiary amines to yield the fixed-charge containing derivatives. The proposed method was tested using aliphatic, terpenoid and steroid alcohols. MALDI and SALDI mass spectra of all derivatives contained intense ion peaks corresponding to their cationic parts.

Разработана методика определения фосфонилированного тирозина – маркера экспозиции к фосфорорганическим отравляющим веществам (ФОВ), в сухих образцах плазмы крови методом тандемной жидкостной хроматомасс-спектрометрии высокого разрешения. Показана стабильность сухих образцов при хранении в течение 2-х месяцев при температурах 22 и 40 оС при использовании в качестве носителя бумаги «Protein Saver 903 Card». Установлено, что температура хранения оказывает значительное влияние на стабильность сухих образцов: при повышенной температуре содержание определяемых соединений снижается практически в три раза в сравнении с такими же образцами, хранившимися при комнатной температуре. Показано, что в отсутствие специальной бумаги возможно использовать в качестве носителя фильтровальную бумагу «синяя лента». При этом аддукты ФОВ с тирозином надежно определяются через 1 месяц после хранения образцов при комнатной температуре (22 оС). В условиях повышенных температур (40 оС) использование фильтровальной бумаги не рекомендуется. Предложенный способ хранения и анализа образцов позволяет отбирать большие серии образцов и легко транспортировать их, а также автоматизировать процесс анализа. Сухие пятна могут доставляться в лаборатории по всему миру в обычных конвертах без обязательных для жидких биообразцов согласований.
A procedure for the determination of phosphonylated tyrosine, a marker of exposure to organophosphorus nerve agents, in blood plasma dry spot (DBS) samples by means of liquid chromatography/tandem high resolution mass spectrometry was developed. The DBS samples on Protein Saver 903 Card substrates were shown to be stable for 2 months on storage at 22 and 40 оС. It was found that the temperature of storage has a high impact on the stability of the DBS samples: the concentration of the analyte in the samples stored at 40 оС was about 3 times lower compared to the samples stored at room temperature. It was shown that the special Protein Saver 903 Card substrates could be replaced by an ordinary blue ribbon filter paper. In the latter case, the tyrosine adducts of nerve agents were reliably determined in the DBS samples stored for 1 month at room temperature (22 оС). However, for storage at elevated temperatures (40 оС), the use of filter paper substrates is not recommended. The proposed approach to storage of blood samples allows one to take and easily transport large series of samples and automate their analysis.

Одной из центральных задач технико-криминалистического исследования документов является установление времени и последовательности нанесения записей в документ такими распространенными средствами письма, как шариковые ручки. Для её решения требуется получить информацию о составе компонентов паст шариковых ручек, которыми исполнялись записи, о том, какие качественные и количественные изменения претерпели компоненты во времени после нанесения записей на документ, а также о том какие изменения наблюдались с компонентами чернил под воздействием окружающей среды либо под воздействием внешних источников таких как фото-, термо-, УФ-, ИК-, микроволновых излучений. В этой связи, целью данной работы являлось развитие подхода, позволяющего выявлять изменения в составе паст ручек, протекающих в штрихах с течением времени, а также установление временных зависимостей, с помощью которых стала бы возможной оценка срока давности исполнения записей. В результате работы оценены возможности жидкостной хроматографии/масс-спектрометрии при обнаружении изменений в составе паст шариковых ручек BIC Original, Corvina 51 и Pilot. Проведено моделирование процессов деградации красителей при воздействии на штрихи УФ-излучения и определены кинетические параметры, описывающие степень превращения красителей.
One of the central problems of documents forensic examination is the determination of the ink deposition date by such common writing instruments as ballpoint pens. To solve this problem, it is necessary to get information about the composition of ballpoint pen inks that were used for depositing inks, to get information about qualitative and quantitative changes of components undergoing in time after depositing inks on a document, as well as to know changes in the composition and properties of the ink caused by environmental influences or intentional effects on document such as photo-, thermal-, UV-, IR-radiations, microwave and other types of external influences. Therefore, the purpose of this research was to develop an approach that allows one to detect changes and establish dependence of these changes in the ballpoint pen composition that occur in strokes over time. As a result of this study, the possibilities of liquid chromatography/mass spectrometry for the detection of changes over time in the composition of ballpoint pen inks BIC Original, Corvina 51 and Pilot were estimated. Modeling of the dyes degradation under the influence of UV radiation on strokes was carried out. Kinetic parameters that describe the degree of dyes conversion were determined.
