Published: September 2024

Abstract
This study aims to investigate the effects of manure and vermicompost in terms of soil elasticity modulus changes in loam soil. The uniaxial compression test measures the compressive strength of a soil cylinder without any lateral load. The modulus of elasticity was determined by plotting the strain-stress diagrams and calculating the slope of these diagrams. The increase in moisture and organic matter content significantly improved soil flexibility and decreased its elasticity modulus. It was found that adding animal manure had a greater effect on the flexibility of the soil as compared to vermicompost, while the elasticity modulus of the samples containing animal manure was lower. The interaction effect of moisture and the organic matter content indicated that the increase in humidity was more effective in the soil containing vermicompost as compared to the soil containing manure, such that when the manure rate was around 19%, the moisture increase had no significant impact on the elasticity modulus. It was found that adding organic matter was more effective at the low moisture level of 15.5% than at higher moistures where the effect of adding organic matter did not affect the soil elasticity modulus decrement as strongly.

Published: September 2024

Abstract
The introduction of the obligation to prepare ESG reports taking into account EU Taxonomy is a challenge for enterprises, but at the same time opens up the possibility of using disclosures in this area to assess entities in the context of environmentally sustainable activities. Legal changes in the field of the Green Deal have been introduced in the last three years, and in the area of EU taxonomy this process is still ongoing, resulting in a deficit of research on the effects of implementing the new legal regulations. The main goal of our study is to assess the importance of the newly applicable ESG reporting and environmental disclosure requirements under EU Taxonomy in improving the quality and comparability of sustainability reporting and the creation of ESG ratings. A qualitative research method was applied based on multiple case studies using content analysis on the basis of ESG reports for 2021-2022 for entities listed on the Warsaw Stock Exchange. The research results indicate a very low level of activities classified as environmentally sustainable and taxonomy-aligned. Additionally, the results may also indicate problems with implementing the new solutions in reporting practice. At the same time, a positive impact is noted of the implementation of taxonomic reports on improving the comparability and detail of disclosures.

Published: September 2024

Objective: The aim of this study is to analyze the importance of various assets as safe havens (hedges) for investment protection, considering systemic risk events, such as the case of COVID-19.

Theoretical Framework: In the study, the behavior of the Brazilian Stock Exchange Indicator is discussed, considering the pandemic period, as well as its relationship with other important financial market assets, such as gold, oil, and the dollar.

Method: Due to the adequacy of the data, considering differences and cointegration, the methodology used in the study was the Autoregressive Distributed Lag (ARDL) model, proposed by Pesaran et al. (2001).

Results and Discussion: The results reveal significant implications for portfolio management in situations of financial risk, highlighting the volatility of the exchange rate and gold, as well as the impact of oil prices on the Brazilian stock market. The estimation of the error correction term found an adjustment speed of 5.7%, indicating a significant long-term association between the variables.

Research Implications: The research highlights that, in the short term, oil and gold prices affect stock indices differently compared to the exchange rate, while in the long term these effects are similar. Thus, for the exchange rate, entry and exit points for investments should be defined. The results are crucial for investment managers and policymakers, especially in contexts of systemic risk.

Originality/Value: The research provides valuable insights for managers and investors, highlighting the importance of understanding the historical behavior of economic variables across different time horizons. Future studies can explore alternative methodologies and consider various economic contexts to enhance the understanding of financial asset behavior, as each country may present a different reality.

Published: September 2024

In the study, we aimed to assess the public perceptions of the prevalence, satisfaction and challenges of electronic health (e-health) services in Bangladesh. An online survey with a self-administered structured interview was conducted with 150 respondents to collect general perceptions from people living in rural and urban areas. The study revealed that the prevalence of e-health services was moderate in Bangladesh. During the COVID-19 pandemic, people accessed online vaccine registrations (58%) and telemedicine (23%) and downloaded COVID test reports (17%). The study did not find an association between e-health services and the respondents’ age, gender, living conditions and marital status based on the results of the chi-square test and the Mann-Whitney U test (p > 0.05). Spearman’s correlation coefficient confirmed that individuals were moderately satisfied with their access to e-health services (r = .536), the availability of updated COVID-related information on websites (r = .585), and government advertisements (r = .547). The respondents reported major challenges such as high internet costs, lack of awareness, insufficient internet speed, and an information gap regarding e-health services in Bangladesh. These results offer important insights to laypeople, health experts and practitioners, policymakers and government health authorities.

Authors: Fristikawati Yanti 
Published: September 2024

Salah satu hak yang dimiliki manusia adalah hak untuk hidup, di mana hal ini terkait juga dengan Upaya penghapusan kemiskinan agar manusia dapat memenuhi kebutuhan hidupnya. Manusia harus dilindungi dari berbagai ancaman termasuk ancaman dari kemiskinan yang merupakan bagian dari Sustainable Development Goals (SDG’s) di mana setiap manusia atau individu harus dijamin oleh negara agar tidak menderita kemiskinan. Tujuan yang pertama dari SDG’s adalah Menghapuskan Kemiskinan, namun di sebagai belahan bumi, masih terdapat kemiskinan sehingga mengancam kehidupan mereka, di mana mereka tidak dapat memenuhi kebutuhan hidupnya termasuk akses kesehatan, nutrisi buruk bagi anak-anak dan pendidikan yang baik. Salah satu penyebab kemiskinan adalah menurunnya kualitas lingkungan, terutama untuk mereka yang mengandalkan alam untuk kehidupan sehari-hari seperti nelayan dan petani, di mana bila lingkungan rusak, maka hasil tangkapan berkurang dan hasil panen pun menurun. Permasalahan yang akan dibahas dalam tulisan ini adalah bagaimana pengaturan tentang perlindungan lingkungan khususnya yang terkait dengan lingkungan laut dan lahan serta peran negara agar tidak dapat mengurangi kemiskinan. Metode penelitian yang digunakan adalah Yuridis-Normatif yaitu kajian Pustaka baik dari buku, jurnal, dan aturan di Indonesia. Salah satu cara untuk menanggulangi kemiskinan adalah dengan menjaga atau melindungi lingkungan agar tidak tercemar atau tidak terjadi penurunan kualitasnya. Pengaturan tentang perlindungan lingkungan dan juga peran atau tanggung jawab negara diperlukan sebagai upaya untuk menanggulangi kemiskinan. Aturan di Indonesia sudah cukup untuk melindungi lingkungan. Indonesia juga telah ikut serta dalam pembahasan mengenai tujuan Pembangunan berkelanjutan ini yang menghasilkan suatu Deklarasi SDG’s pada tahun 2015. Komitmen internasional ini menjadi tanggung jawab masing-masing negara agar dapat dilaksanakan di negaranya. Diharapkan agar aturan yang ada tentang perlindungan lingkungan dapat diterapkan termasuk pula adanya peran serta negara atau pemerintah, sehingga lingkungan tetap terlindungi dan kemiskinan dapat ditanggulangi.

The paper reports the results of study of composition, emission, and optical properties of polycrystalline W and Mo samples implanted with Ba+ ions and coated with submonolayer Ba atoms by applying Auger electron spectroscopy, secondary electron emission coefficient s technique, as well as the photoelectron quantum yield Y. The experimental part was carried out by using the instrumentation and under vacuum Р ≈ 10-6 Pa. It is shown that during the implantation of Ba ions in the surface layers of refractory metals, a mechanical mixture of the W + Ba and Mo-Ba types is formed. It has been established that the values of the coefficient of secondary electron emission s and the quantum yield of photoelectrons Y at the same value of the work function еφ in the case of implantation of Ba+ ions are much larger than in the case of deposition of atoms. The obtained experimental results are substantiated by theoretical calculations.

Complex methods of physical and chemical analysis: differential thermal analysis (DTA), X-ray phase analysis (XRD), microstructural analysis (MSA), as well as density and microhardness measurements, were used to study the nature of chemical interaction in the Ho-Sb-Te ternary system over the entire concentration range along the following sections:1. Sb2Te3-Ho2Te3, 2. Sb2Te3-HoTe, 3. HoTe-Sb, 4. HoSb-HoTe, 5. Sb2Te3-Ho, 6. HoSb-Te. The projection of the liquidus surface of the ternary system and the diagrams of the state of internal sections were constructed according to experimental data and literature data on binary systems: Sb-Te, Sb-Ho, Ho-Te. It is established that sections (1), (2), (3), (4) are quasi-binary, and (5), (6) are non-quasi-binary sections of the ternary system. The incongruently melting compound HoSbTe3 is formed in the Sb2Te3-Ho2Te3 system and the area of solid solutions based on Sb2Te3 ~ 3‑5 mol% at 300K was found.

Published: September 2024

The produced ZnO<S> films were characterized with the crystallographic orientation (001) and lattice parameters a = b = 0.3265 nm and c = 0.5212 nm. ZnO1—хSх nano-crystallites on the surface of the film had characteristic sizes ranging from 50 nm to 200 nm. The lattice parameter of ZnO1—хSх nano-crystallites was experimentally determined to be aZnO<S>= 0.7598 nm. The study has shed light on what occurs to lattice parameters of the ZnO film and the geometric dimensions of ZnO1—хSх nano-crystallites on the surface of the film under the influence of gamma-irradiation. It has been determined that the crystal structure of ZnO1—хSх nanocrystallites represents a cubic lattice and belongs to the space group F43m. It has been determined that after γ-irradiation at doses 5∙106 rad, the resistivity of ZnO<S> films reduced to ρ = 12,7 W∙cm and the mobility of the majority charge carriers (µ) became 0.18 cm2/V∙s, whereas their concentration (N) had increased and equaled 2.64∙1018 cm-3. The study of the current-voltage characteristics of p- ZnO<S>/n-Si heterostructures before and after γ‑irradiation at doses of 5∙106 rad revealed that the dependence of the current on voltage obeys an exponential law which is consistent with the theory of the injection depletion phenomenon. It was determined that under the influence of γ-irradiation at doses of 5∙106 rad, the capacitance of the p-ZnO<S>/n-Si heterostructure at negative voltages increases and the shelved curve sections and peaks are observed on the curve due to the presence of a monoenergetic level of fast surface states at the heterojunction.
SCAPS Numerical Analysis of Graphene Oxide/Zirconium Disulfide Solar Cells
Authors: Al-Dmour Hmoud 
Published: September 2024

This work studies the performance of solar cells composed of two different materials, graphene oxide (Go, hole transport material) and zirconium disulfide (ZrS2, electron transport materials) using the SCPAS -1D simulation. It has been found that Go/ZrS2 solar cells show better performance with high short circuit current, Jsc, of 38 mA/cm2 and the power conversion efficiency, η, of 17% compared with other solar cells based on graphene oxide and perovskite materials. Additionally, the short circuit current density decreases from 38 mA/cm2 to 22 mA/cm2 when the energy gap of ZrS2 increases from 1.2 eV to 17 eV. The increasing the operating temperature and the work function of back contact also led to decrease the open circuit voltage and power conversion efficiency of the cells, while the short circuit current density was slightly enhanced. That is attributed to changes in the electrical properties of Go and ZrS2 layers, including their charge carrier mobility and characteristics of the interfacial layers.
