The ways of creating a trust
Authors: Digori Irina
Published: October 2024

This article explores the ways of creating a trust, according to Article 2074 of the Civil Code of the Republic of Moldova. To shed light on the legislative inspiration and the distinct characteristics of various methods of establishment, a comparative analysis is conducted concerning the provisions outlined in Book X (Trusts) of the Draft Common Frame of Reference, as well as the Civil Codes of the Province of Quebec, France, Romania, and the Republic of Moldova. The discussion emphasizes the ways for voluntarily creating a trust, namely by contract, unilateral declaration, and will, all of which are comprehensively regulated. Additionally, the article addresses the mechanism of creating a trust through administrative act or court decision, situations that necessitate explicit legislative regulation before implementation. The paper also delves into the relationship between ‘law’ and ‘administrative act’ as sources of trusts, presenting a hypothesis that the legislator intentionally substituted this term in the legislation of the Republic of Moldova.

President of the Republic of Belarus – head or head of state?
Authors: Скороход Игорь
Published: October 2024

Using linguistic and historical and legal methods, the author set out to show that the President of the Republic of Belarus is not the head of state, but the head of state. It is noted that the constitutional content of the concept of “head of state” does not significantly depend on the form of government. The issues of incorrect translation and substitution of words in аrt. 79 of the draft Constitution of the Republic of Belarus at the republican referendum on November 24, 1996. As a result, the President of the Republic of Belarus unreasonably, in addition to the will of the people, received the status of ,,Head of State”. An assessment of the consequences for the country and society of the ,,President-Head of State” union is given. It is shown that such a combination allows the President not to act, but to rule alone, which leads to the formula: ,,president” – ,,head of state” – ,,sovereign”. In conclusion, it is concluded about the monarchization of the institution of the presidency and the formation of a new atypical form of government in the country – the ,,republican elected monarchy”.

Authors: Vrabie Dina
Published: October 2024

In the procedure for returning or exercising the right of visitation , the child’s opinion is to be considered, as is done in many other matters concerning the child’s rights and interests. International provisions allow administrative and judicial courts not to order the child’s return, in cases where he objects. And given the fact that the procedure for returning or exercising the right of visitation was established with the aim of protecting the exclusive child’s interests, his opinion must be considered, if it’s found that his age and degree of maturity allow him to perceive and expose themselves to the situation in which he is.

Authors: Cristea Daniel , Calendari Dumitru
Published: October 2024

Even if the legal system has a clear regulation regarding the conduct of the criminal process, in the application of which the principle of human dignity must be respected, we cannot say that this principle of human dignity cannot or has not been violated. The legislative shortcomings must be removed so that there is no possibility of taking advantage (abuse of authority). They can be considered fundamental defects that can affect the decisions of the courts. The examination and analysis of the normative framework will be presented in order to comply with and implement some procedural guarantees of protection and respect for human dignity within the evidentiary procedures. So said, the result of the research resides, on the one hand, in the systematization of the works in the field and the laws in force, with the highlighting of the most important ideas that refer to the object of study but, at the same time, also an attempt to analyze the aspects their positive and critical aspects, formulating their own ideas regarding respect for the principle of human dignity. On the other hand, practical aspects of the violation of the principle of human dignity are addressed in order to highlight its particularities in practice, the legal bodies. The conducted study thus allows establishing the directions and trends of the procedural-criminal policy promoted along the lines of ensuring and realizing the right to respect the principle of human dignity.

Authors: Cebotari Valentina , Strelciuc Viorica
Published: October 2024

With the registration of the marriage certificate, the spouses are mutually and jointly obligated to provide each other with material maintenance and moral support, both during the marriage and after its dissolution. When establishing the payment of alimony from the spouses, both the period of cohabitation of the spouses that gives the right to maintenance and after the dissolution of the marriage will be taken into consideration. The role of the court is essential, manifested through the meticulous examination of all the factual and legal circumstances that influence good faith in the right to receive maintenance from a spouse or former spouse. When determining the right that gives rise to the maintenance obligation, the court will assess the evidence submitted in the case, taking into account the principle of good faith or its absence. The court may dismiss the application if it considers that the spouse requesting the maintenance obligation has acted contrary to good faith.
A Comparative Analysis of Dramatic Structure in Lorraine Hansberry’s A Raisin in the Sun (1959) and August Wilson’s Fences (1986)
Authors: El Bakal Mohamed , Amesnaou Mohamed
Published: October 2024

This paper conducts a comparative analysis of the dramatic structures in Lorraine Hansberry’s A Raisin in the Sun and August Wilson’s Fences, utilizing Freytag’s Pyramid as a framework. Despite differences in scene and act composition, both plays share a similar narrative structure marked by multiple climactic points rather than a single one. Each play presents the lives of African American families in mid-20th century America, grappling with themes of racial oppression, economic hardship, and personal aspirations. Hansberry’s work primarily addresses the relationship between African Americans and White society, while Wilson’s focuses on intergenerational conflicts within a Black family. Both playwrights weave moments of heightened tension throughout the narratives, surprising audiences with new inciting incidents just as the action seems to be falling. This study reveals that although Fences was written nearly 30 years after A Raisin in the Sun, the two plays mirror one another in their exploration of socio-economic struggles and racial dynamics. Ultimately, the paper illustrates how both works encapsulate a continuous struggle for dignity and self-actualization within the constraints of a racially discriminatory society.
Bengali Translation and Validation of Academic Resilience Scale in Bangladeshi School-Going Students
Authors: Ahmed MD. Faisal
Published: October 2024

This study aimed to translate and validate the Academic Resilience Scale (ARS) for use among Bangladeshi school students in Bengali. The ARS, developed by Martin and Marsh, measures students' ability to cope with academic challenges. This study addresses the gap in validated Bengali instruments for assessing academic resilience. A cross-sectional design study involving 234 students aged 12-18 years from two schools in Dhaka, Bangladesh, was used. The ARS underwent a rigorous translation process, which included two forward translations, two back translations, and comparisons of the original and translated versions. The data collected were collected by administering both the original and translated ARSs, with a one-week interval between administrations. Analysis was conducted using SPSS 29.0, employing descriptive statistics, Pearson correlations, Cronbach’s alpha, and independent sample t-tests. Descriptive statistics revealed mean scores for the original ARS (M = 23.78, SD = 7.456) and the translated ARS (M = 23.77, SD = 7.516), indicating similar levels of academic resilience. Pearson correlations between the original and translated items ranged from .909 to .941 (p < .01). Cronbach’s alpha was 0.747 for the original scale and 0.754 for the translated ARS, demonstrating acceptable reliability. No significant sex differences in resilience scores were found for either version. The Bengali-translated ARS is a reliable and valid tool for measuring academic resilience among Bangladeshi students. This validated scale offers a valuable resource for future research and interventions aimed at improving academic resilience. Future studies should address limitations and explore resilience factors in diverse contexts.

Freedom and Bondage: An Interpretation of the Concept of Freedom in Middlemarch
Authors: Song Jialu , Li Tao
Published: October 2024

George Eliot, a renowned female writer and philosopher of the Victorian era, significantly embodied her philosophical ideas within her novels. The characters in Middlemarch relentlessly pursue freedom amidst the constraints of human nature, legal frameworks, and personal desires. This paper posits a remarkable resonance between George Eliot’s concept of freedom in Middlemarch and Baruch de Spinoza’s interpretation of freedom in his philosophical work, Ethica. However, Eliot’s creation of Middlemarch was not intended to serve as a vehicle for Spinoza’s view of freedom. Spinoza’s concept of freedom provided solid theoretical support for Eliot’s literary creation, and based on this, Eliot deepened the concept of freedom within Middlemarch, demonstrating her profound understanding and development of Spinoza’s ideas. Furthermore, this paper also reveals the complex societal issues and sharp human contradictions highlighted in the characters’ pursuits of freedom in Middlemarch. By analyzing Eliot’s thoughts on freedom and examining the influence of Spinoza’s view of freedom on her creation, this paper aims to open up a new path to help readers gain a more comprehensive grasp of Eliot’s philosophical ideas and the implications embedded within her literary oeuvre.

Authors: Zhao Tingting
Published: October 2024

Objective: The paper aimed to explore the significance of serum sST2 and cfDNA to prevent atrial inflammation in children with severe pneumonia complicated by myocardial damage. Methods: 120 children with severe pneumonia complicated by myocardial damage who were treated in the Children's Department of the author's hospital from April 2021 to December 2023 were recruited as research subjects. The children were randomly divided into two groups, one group of 60 children received personalized care intervention based on serum sST2 and cfDNA (personalized care group), and the other group of 60 children received routine care (routine care group). The clinical data of the two groups of patients were compared. The changes in serum sST2 and cfDNA levels of patients were compared before and after care. ELISA kits were used to test atrial inflammation marker levels before and after patient care. The patient's cardiac function was assessed through cardiac ultrasound. the nursing intervention effects of the two groups was compared. The patient satisfaction with nursing care was compared between the two groups. Results: There was no distinction in the general record of the two groups (P>0.05). Before care, there was no distinction in serum sST2 and cfDNA levels between the two groups (P>0.05). After care, the serum sST2 and cfDNA levels in the personalized care group were lower than those in the routine care group (P<0.05). There was no difference in CRP, cTn, 1L-6 and TNF-α between the two groups before nursing (P>0.05). After nursing, the levels of CRP, cTn, 1L-6 and TNF-α in personalized nursing were lower than those in the conventional nursing group (P<0.05). Parameters such as EF and E/A in the personalized care group were higher than those in the routine care group (P<0.05). The LVEDd and LVESd in the personalized care group were smaller than routine care group (P<0.05). The improvement rate of cardiac function, remission rate of atrial inflammation and 6-month re-hospitalization rate in the personalized care group were lower than conventional care group (P<0.05). The very satisfied rate in the personalized care group was higher than routine care group (P<0.05), and the dissatisfaction rate in the personalized care group was lower than routine care group (P<0.05). Conclusion: Personalized nursing intervention based on serum sST2 and cfDNA can significantly improve the cardiac function of children with severe pneumonia complicated by myocardial damage, reduce the levels of atrial inflammation markers, and advance the satisfaction of children and their families.

Abstract
Forest damage caused by deforestation and degradation is one of the five most important environmental problems. Global warming is an important issue that occurs due to economic activities that are carried out without paying attention to the environmental impacts that have caused the temperature on earth in recent years. This can lead to a decrease in carbon sequestration in the forest. The purpose of this study was to determine the potential for biomass, carbon storage, and carbon dioxide uptake above and below ground in Banten Grand Forest Park. The method of placing the plot is purposive sampling, while the technique of collecting biomass data is the destructive and allometric approach. The results show that there is no significant difference between total biomass, carbon storage, and carbon dioxide absorption between mixed forest, reforestation plantations, and Shorea leprosula plantations in Banten Grand Forest Park. The values of biomass, carbon storage, and carbon dioxide absorption were 30.70-46.23 tons/ha, 14.43-21.73 tons C/ha, and 52.95-79.75 tons CO2/ha, respectively.

Published: October 2024

ABSTRACT
The Gunung Dahu Research Forest Area was originally degraded land that was converted into forested land through a revegetation program with dipterocarp tree species in 1997. Intensive revegetation activities within the area have increased forest cover and increased water infiltration capacity. This study aims to determine the effect of changes in land cover and stand characteristics on hydrological characteristics in the Gunung Dahu Research Forest. The results showed that revegetation activities had increased forested land cover to 113.8%. This increase in forested area is supported by an increase in standing stock volume up to 276 m3/ha. This increase plays an important role, especially in increasing infiltration capacity due to the deeper tree roots. Changes in land cover were influenced by hydrological conditions with an increase in lateral flow of 127%, baseflow of 483.8%, and a decrease in surface runoff of 5.8%. Forested land cover is important so that water sources are maintained and can be sustainably utilized by the community.

ABSTRAK
Kawasan Hutan Penelitian Gunung Dahu awalnya merupakan lahan terdegradasi yang diubah menjadi lahan berhutan melalui program revegatasi dengan jenis pohon dipterokarpa pada tahun 1997. Kegiatan revegetasi yang intensif di dalam kawasan telah meningkatkan tutupan hutan dan meningkatkan kapasitas infiltrasi air. Penelitian ini bertujuan untuk mengetahui pengaruh perubahan tutupan lahan dan karakteristik tegakan terhadap karakteristik hidrologi di Hutan Penelitian Gunung Dahu. Analisis perubahan tutupan lahan dilakukan menggunakan data citra satelit Landsat tahun 1997, 2007, dan 2020. Citra ini kemudian dianalisis menggunakan metode klasifikasi terbimbing dan penentuan karakteristik hidrologi menggunakan Soil and Water Assessment Tools. Hasil penelitian menunjukkan bahwa kegiatan revegetasi telah meningkatkan tutupan lahan berhutan menjadi 113,8%. Peningkatan luas berhutan ini didukung dengan peningkatan volume standing stock sampai 276 m3/ha. Peningkatan tersebut telah meningkatkan kapasitas infiltrasi karena semakin dalamnya perakaran pohon. Perubahan tutupan lahan memengaruhi kondisi hidrologi, yaitu peningkatan aliran lateral 127%, aliran dasar 483,8%, dan penurunan limpasan permukaan 5,8%. Tutupan lahan berhutan menjadi penting agar sumber air tetap terjaga dan dapat dimanfaatkan oleh masyarakat secara lestari.

Hutan memiliki peran yang sangat penting dalam menjaga keseimbangan iklim Bumi. Keberadaan hutan dan komponen-komponen penyususnnya memiliki kemampuan untuk mengurangi jumlah karbon dioksida dalam atmosfer. Penelitian bertujuan untuk menghitung konsentrasi simpanan karbon dan menganalisis korelasi antara kerapatan tegakan dan karakteristik tanah terhadap jumlah karbon dalam tanah pada hutan tanaman tegakan campuran Schima wallichii dan Acacia mangium. Penelitian dilakukan teknik pengambilan sampel sistematis berupa jalur sebanyak 5 jalur dan setiap jalur dibuat plot pengamatan berukuran 20 m x 20 m sebanyak 5 plot sehingga jumlah plot pengamatan ada 25 plot. Parameter yang diamati adalah C-organik tanah, kerapatan tegakan, dan bobot isi tanah. Hasil penelitian menunjukkan variasi nilai berat jenis tanah di hutan tanaman tegakan campuran Schima wallichii dan Acacia mangium berkisar antara 0,505 - 0,795 g/cm3, C-organik tanah antara 0,07 - 0,20%. Rata-rata stok karbon dalam tanah mencapai 200,22 ton per hektar. Semakin tinggi nilai C-organik dan kerapatan tingkat pohon, jumlah karbon dalam tanah juga semakin tinggi. Sebaliknya, semakin tinggi bobot isi tanah, jumlah karbon organik dalam tanah cenderung lebih rendah.
Classifying Liver Fibrosis through the Utilization of Transfer Learning and FCNET Classifiers
Authors: S Karthick
Published: October 2024

Abdominal Radiology is used for monitoring patients with liver diseases and to measure severity of liver fibrosis by using Ultrasound (US) images which is obtained by scanning. Scanning uses high frequency sound waves to take images of the affected human organs. Since liver is situated deep into the body the signal get weaker each time it passes through other organs which makes it difficult for diagnosis to overcome this difficult transfer learning technique is proposed in this system. The first step is to remove unwanted disturbances from the US images which is accomplished by pre-processing steps. To ensure the quality of the input images they undergo resizing of resolution, adjusting variations in brightness and contrast. The goal of pre-processing technique is to enhance the quality, uniformity, and relevance of the input images, making them suitable for feature extraction and subsequent classification of liver fibrosis stages. The next step is to apply the Expectation Maximum (EM) algorithm based on Region of Interest (ROI), which is a clustering technique used for image segmentation. The EM algorithm iteratively assigns pixels to different clusters based on their intensities and probabilistic models, aiming to identify distinct regions. The feature extraction process is carried out by Fully Connected Convolutional Neural Network (FCNET) models which enable extracting high level representations from original images and transfer learning classification is used for classification of fibrosis stages with improved accuracy.

This project suggests utilizing a deep learning system to classify IoT networks. The preprocessing technique receives the input data. The dataset’s null and repeated values are eliminated using this method. Following preprocessing, the preprocessed data is moved into the feature selection block. The feature selection process makes use of the chi square. The extraction areas are processed using the Chi Square technique to extract different characteristics and select the aspects that are needed to improve classification. Subsequently, the data extraction procedure moves on to categorization. Convolutional neural networks (CNNs) are utilized for classification based on the model’s performance analysis using CNN classification. This paper provides a useful model to classify IoT network traffic in an actual IoT scenario. The software used to implement this project is Python.
An Investigation of the Convergence of Average Peak Accelerations for High-Speed Planing Craft
Authors: Riley Michael , Murphy Heidi , Aron Brock
Published: October 2024

This paper summarizes the results of an investigation of the convergence of average peak accelerations as more and more peaks are recorded during rough-water trials of small high-speed craft. Existing guidance from multiple sources suggest that more peaks is better, but how much more, and what engineering rationale should substantiate the answer? To address the question, simplified equations and numerous examples of peak acceleration data sets are presented. The results demonstrate that convergence of the average of the highest 10 percent of peaks (A1/10), and the average of the highest 1 percent of peaks (A1/100), and the A1/100 / A1/10 ratio means that the shape of the cumulative distribution of the data set becomes more stable as the number of peak acceleration data points increases. A simple percent-difference criterion is presented for quantifying the stability of the cumulative distribution shape.

Two-spotted spider mite, Tetranychus urticae Koch, is one of the most damaging pests of many economically important crops. The acaricidal, ovicidal and nymphal activity of three essential plant oils viz. neem, mahagoni, castor and two insect growth regulators viz. buprofezin and lufenuron + Emamectin benzoate were evaluated against T. urticae under laboratory conditions and in the potted plants. Results showed that mahagoni oil (100%) and lufenuron + emamectin benzoate(100%) performed the most efficient acaricidal agent againstT. urticae in the laboratory conditions. Mahagoni oil also showed the highestovicidal efficacy (77.2%)and lufenuron + emamectin benzoate (74.6%) showed the second highest ovicidal efficacy against T. urticae. Castor oil showed the lowest percent of ovicidal efficacy (48.1%). In the case of the nymph, the highest average mortality was observed in mahagoni oil (55.4%) followed by lufenuron + emamectin benzoate (52.8%). The lowest nymphal mortality was observed in castor oil (31.3%). In potted bean plants, all the treatments showed a significant reduction in the adult population over control up to 21 days. The adult T. urticae population’s survival rate progressively declined throughout the length of the days after treatment (DAT) for each treatment up to sevendays, then slightlyclimbed up to 21 days. However mahagoni oil (77.8%) and lufenuron + emamectin benzoate (72.2%) showed the highest mite mortality compared to all other treatments. Thereforemahagoni oil and lufenuron + emamectin benzoatewere found to be the most effective to control T. urticae.
