Abstract

Objective:
The main objective of the present study was to characterize the extracts obtained from the bark of three oak species in order to assess their use in potential cosmetic products.

Methods:
The extracts were obtained from the oak barks (periderm and rhytidome) using ultrasound-assisted extraction. The total polyphenolic content was assessed afterward, using the Folin–Ciocâlteu method, while the antioxidant capacity was determined using methods based on the neutralization of the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and 2,2-diphenyl-1-picrylhydrazyl radicals. To assess the tyrosinase inhibitory effect, a protocol using L–DOPA as the substrate of the enzyme was employed.

Results:
The extracts presented high levels of polyphenolic compounds, with Q. cerris having the highest content. Because of the high concentration of the extracts in polyphenolic compounds, they revealed a great reducing capacity against both DPPH and ABTS radicals, but unfortunately the tyrosinase inhibitory activity of the tested extracts was very weak compared to the positive control.

Conclusions:
The extracts may have beneficial effects when used in cosmetic products because of the antioxidant effects, but more studies must be conducted for the determination of the main phytochemical compounds comprised in the extracts and their correlation to the biological effects.

Published: April 2024

Abstract

Objective:
Obesity is defined as the abnormal and excessive accumulation of fat. Enlargement of white adipose tissue due to obesity activates the sympathetic nervous system to stimulate lipolysis to break down fat extensively. This causes a lot of free fatty acids to circulate in the body. Excessive circulating free fatty acids affect many cells and produce oxidative stress, which spreads throughout the body. This research purpose is to determine the anti-obesity and antioxidant activities of ethanol extract of B. pandurata rhizome (EEBP).

Methods:
Fingerroot rhizomes were extracted using maceration and the extract was used for in vivo, antioxidant, and total flavonoid concentration tests. Anti-obesity test was carried out by dividing mice into 6 groups such as normal controls, obese controls, standard groups, and extract-treated groups (100, 200, 400 mg/kg b.w). The in vivo test parameters observed included measurement of body weight and also liver, kidney, spleen, and retroperitoneal fat index measurement. Furthermore, in this research antioxidant test was performed using the DPPH method.

Results:
In vivo test showed that the giving of EEBP at a dose of 400 mg/kg b.w. effectively decreased body weight and retroperitoneal fat, but slightly affected the organ index of mice such as the liver, renal, and spleen. Furthermore, the antioxidant test showed that the IC50 EEBP results obtained were 37,05 µg/ml. In addition, the total flavonoid content found in the EEBP is 15,775 mgQE/g.

Conclusion:
The present study showed that EEBP may have a considerable potential anti-obesity agent and also has a very strong antioxidant effect.

Abstract
Crises such as the COVID-19 pandemic challenge some established human-landscape interactions notably. In this article, we analyse whether the pandemic had an impact on the perception of urban green spaces (UGS) and usage behaviours in Leipzig, Germany. We use a quantitative survey to understand people’s attitudes. Our study is novel in that it firstly explores the relationship between UGS and visitors during the final phase of the COVID-19 pandemic (winter 2022/2023), contrary to the vast majority of already existing studies that relied on digitally distributed surveys due to the lockdown protocols. Secondly our study does not apply exclusively online methods to reach out to the participants. The survey results show that about 40% (of the 115 participants) use parks more frequently during the final phase of the COVID-19 pandemic compared to before 2020. Characteristics such as proximity to home, naturalness and cleanliness have become the most relevant. We see a notable increase in the demand for secure public green spaces, particularly among female visitors. Every second respondent confirmed experiencing considerable difficulties when accessing UGS, revealing the existing (spatial) deficits in environmental justice. These results should be considered by urban planners to adapt UGS to the changing demands of the citizens.

Abstract
In this article, we identify the spatial mobility of the populations of selected urban centres in Poland, Romania, Slovakia and Hungary. In total, 1,616 interviews were conducted. Additionally also interviews with the employees responsible for crisis management were conducted. Based on the analyses, five different clusters were identified, with different patterns of inhabitants in terms of their spatial mobility in the event of war. The most significant factors influencing their mobility in crisis situations are country of residence, age, number of people in the household and sex. This research can help develop evacuation strategies at different levels of governance.

Abstract
This paper highlights the results of an experimental study on the preparation and characterization of Luffa cylindrica fiber (LCF) and groundnut shell particle (GSP) reinforced phenol-formaldehyde (PF) hybrid composites. The amount of LCFs was fixed at 25 wt%, while the amount of groundnut shell particles ranged from 0 to 25 wt%. Observations were made regarding the water absorption and thickness swelling behaviour of prepared hybrid composites. In addition, the mechanical behaviours of hybrid composites have been studied under both dry and wet conditions. In comparison to dry conditions, the mechanical properties of the hybrid composites were lower when they were wet. Hybrid composites comprising 25% Luffa cylindica fibre and 15% groundnut shell particle (25LCF/15GSP) exhibit the highest level of mechanical properties under both conditions. The percentages of water absorption and thickness swelling increase as groundnut shell particles increase. The composite 25LCF/25GSP exhibited the highest percentage of water absorption and thickness swelling. Compared to date palm leaf (DPL)-reinforced composites, 25LCF/15GSP showed more significant mechanical and physical properties. We concluded that the inclusion of groundnut shell particles in LCF/PF composites substantially improved the mechanical properties of the hybrid composite. The range of increment, however, was narrower under moist conditions compared to dry conditions.
Carbon Credits and Crude Oil: An Investigation of the Price Returns Interaction in the International Market
Authors: de Salles André Assis , Lima Renato Barros 
Published: April 2024

Abstract
This paper aims to verify the relationship between the international markets for crude oil and carbon credits. We studied the returns of prices practiced in these markets, focusing on the transmission of shocks between oil prices and carbon credit prices. The methodological approach used financial econometrics to study these variables’ risk and return relationships. Besides causality and cointegration hypothesis tests, the VECM and GARCH models were estimates. There is a short- and long-term interaction between these variables. The volatility models show a significant association between the volatilities of the two variables of interest. Fossil fuels, mainly crude oil, generate energy that has substantial restrictions. At the same time, the carbon credits market has shown significant growth that can contribute to the use of energy from fossil fuels with parsimony and responsibility. Studying these variables and their interactions contributes to understanding the importance of the carbon market.
EU Health Union: Legal Aspects and Digital Health

Published: April 2024

Abstract
Recurrent health crises and outbreaks of infectious diseases of international concern have created a specific EU public health policy. Its role was further strengthened by the COVID-19 pandemic, which triggered the next stage in the integration process of the Member States: the European Health Union. The research is carried out using a literature review method (a review of literature and documents in the field of public health policy and the European Health Union) and a comparative-legal method for comparing EU legal acts on which the Health Union is based (endogenous comparison) and the legal acts of EU and the Republic of Slovenia (exogenous comparison). The findings are examined using a qualitative content analysis method, which allows for meaningful aggregation and use of the data under study to answer the research questions. The European Health Union builds on and extends existing areas of public health and requires greater integration between Member States. One of its most essential pillars is a single information system with a single database to improve the health of individuals, resilience to cross-border health crises, patient mobility, and joint research on the most severe diseases. Member States, including Slovenia, must follow EU public health commitments. As the Slovenian legislative proposal analysis on the digitalization of healthcare shows, this challenging task will also require respect for the institute (safeguards) of other areas of law.

Published: April 2024

Abstract
This research paper focuses on enhancing the surface characteristics of the 316 stainless steel (SS316) alloy, including roughness, microhardness, and corrosion resistance. Where the application of ND-YAG laser technology, a highly relevant and timely area, was investigated deeply. The Q-switching Nd: YAG Laser was used with varying laser energy levels within the context of the laser shock peening (LSP) technique. The corrosion resistance of the 316 ss alloy is evaluated in a corrosive environment of 500 mL of saliva (with a pH of 5.6) through electrochemical corrosion testing. Corrosion rate was determined based on the analysis of polarization curves. The outcomes of this research reveal that as the laser energy was increased, there was a noticeable enhancement in the mechanical properties of the 316 ss alloy’s surface. Importantly, the corrosion rate experiences a significant reduction, decreasing from 4.94 mm/yr to 3.59 mm/yr following laser shock peening (LSP) application.
