Balancing Tourism and Community Well-Being: Evaluating Pilgrimage Services in Częstochowa
Authors: Ingaldi Manuela 
Published: January 2025

Abstract
As people seek novel and engaging experiences during their leisure time, places of worship and religious sites emerge as popular tourist destinations. In Poland, Częstochowa stands out as one such revered location, home to the Black Madonna Monastery. Annually, approximately 4 million tourists flock to this sanctuary, with many opting for pilgrimages on foot.
While visiting Częstochowa, tourists rely on well-prepared infrastructure to facilitate their stay. However, some residents, particularly those living near the sanctuary, express grievances regarding the inconveniences caused by the influx of tourists. Achieving a harmonious balance between the needs of tourists and those of the residents is imperative. While tourists contribute significantly to the city’s revenue, residents strive to maintain a semblance of normalcy amidst the tourist influx.
Therefore, analyzing residents’ perspectives is crucial to identify areas needing improvement concerning pilgrimage-related activities and to gauge resident satisfaction levels. This paper aims to assess the impact of tourism services on the development of Częstochowa and the daily lives of its residents. Conducted through direct interviews with Częstochowa residents, the research employed the Critical Incident Technique (CIT), typically used for evaluating service quality. This method not only facilitated the organization of obtained data but also highlighted areas needing enhancement. Following the direct interviews, the analysis phase commenced, wherein critical incidents were identified, categorized into positive and negative incidents, and further grouped accordingly. Subsequently, a matrix classifying critical incidents was constructed to identify particularly impactful incidents and those causing significant resident dissatisfaction. The research findings were then presented to city authorities to pinpoint areas for potential improvement as identified by residents. These recommendations aim to not only foster the city’s development but also enhance residents’ quality of life. Such initiatives constitute significant strides towards fostering sustainable tourism in Częstochowa.

Authors: Silva Pablo Dutra da , Filho Pedro Bertemes 
Published: January 2025

Abstract
Wearable and portable devices are gaining significant popularity across consumer electronics as well as in medical and industrial fields. To ensure that these devices are both comfortable and appealing to users, they need to have low battery consumption and be compact in both size and weight. The EGluco project is focused on developing a wearable device for non-invasive blood glucose monitoring. This multi-sensor device incorporates electrical bioimpedance spectroscopy as one of its measurement techniques. One of the earlier versions of the device was deemed unsuitable as a wearable due to its large size and high power consumption. To make the device more suitable for wearability, the previous hardware was assessed, and a new design was proposed that simplified the system’s power supply and reduced the operating voltage. This article presents two of these designs: an improved Howland current source with a supply voltage of 3.3 V, an output current of 250 μA, and the ability to conduct bioimpedance analysis up to 1 MHz using pulsed DIBS (Discrete Interval Binary Sequence) signals, and an instrumentation amplifier with the same supply voltage as the current source, a voltage gain of four, and a slew rate of 150 V/μs. By simplifying the power supply and implementing other changes, the device’s size was reduced to a single 5 × 5 cm circuit board, compared to the previous configuration of four separate boards connected by cables.

Abstract

Background
A stuck leaflet is a rare complication of transcatheter aortic valve implantation (TAVI). It occurs when one of the leaflets in the implanted valve doesn’t open and close properly. This complication can lead to serious health problems, even death.

Case presentation
We describe a rare case of a stuck “open” leaflet after TAVI. To our knowledge, this is the first reported case in which this frightening complication has been resolved by ballooning procedure, with no need for another valve implantation.

Conclusions
This case highlights the potential role of ballooning procedure as a treatment for stuck leaflets after TAVI.

Abstract
In this work, it was proposed to replace the conventional reinforcement of the unsaturated polyester resin by a mineral, from a siliceous volcanic rock of volcanic nature, perlite. UPR/perlite composites with different proportions of phase components (from 1% to 5% of powder mass part). We used unsaturated polyester resin (UPR) as well as the hardener cobalt octoate and treated and untreated perlite of different dimensions (greater than 60µm, and less than 60µm). The composites were prepared by the contact molding process. The composite plates are hardened for 24 hours at room temperature then placed in an oven for 15 hours at 50°C to undergo post-curing. The composites obtained were subjected to different characterization techniques, namely rheological tests (dynamic mechanical analysis (DMA)), thermal tests (differential calorimetric analysis (DSC)) and Thermogravimetric analysis (ATG) and structural characterization by Fourier transform infrared (FTIR). The DMA measurements showed that the UPR/perlite composites with untreated filler presented conservation modules higher than that of the resin without perlite for the rates of 3% and 4%, while for the composites with treated filler, that at 3% of perlite shown the highest modulus along the glassy zone. Also, the glass transition temperature of the UPR resin was not affected by the addition of perlite. The decrease in intensity at mid-height of the tan δ peaks allowed deducing the existence of a fairly strong UPR/perlite interface. DSC thermograms showed that the exothermic peak is shifted to higher temperatures, due to a delay in the curing reaction caused by the presence of the perlite particles. This study concluded that the perlite enhances the properties of composites.

Published: January 2025

Abstract
Built environment contributes significantly to social and economic development, but it is also resource intensive. It is therefore one of the main producers of emissions and carbon footprint. Choosing building designs with a long service life is the key to resolving environmental problems. In this paper, the life cycle of a residential building is evaluated to reduce the greenhouse gas emissions and costs associated with the construction, use and disposal of the building. Life Cycle Assessment and Life Cycle Costing methods were used to evaluate the environmental and financial impact of the residential building. The system boundaries were defined as “Cradle to Grave” and a lifetime of 60 years. The calculation showed that the building emitted 843 tons of CO2e, or 19.8 kg CO2e/m2/year, and the life cycle costs were 2 026 €/m2. Considering the phases considered, the energy consumption phase (B6) caused the highest CO2e emissions, up to 50.1%.

Authors: Belmouhoub Ameur , Abdelouahed Assia 
Published: January 2025

Abstract
Utilizing waste plastic and rubber in civil engineering is one of the most environmentally friendly and economically advantageous options. In this work, the aim was to study the relationship between porosity, ultrasonic pulse velocity, and water absorption using waste plastic and rubber in ordinary concrete and analyze the results with a program called JMP, where cement was replaced with rubber as a mass substitute in proportions of 2% and 4% and sand was replaced with plastic as a mass substitute in proportions of 2%, 4%, and 6%. The tests used were ultrasonic speed at 28 days, porosity, water absorption by total immersion, and sorptivity. The findings reveal that as the amount of rubber and plastic increases, the speed of ultrasonic decreases. Additionally, higher amounts of rubber and plastic lead to increased porosity, water absorption by total immersion, and sorptivity. The speed of ultrasonic pulses varies between 4065.04 m/s and 3838.90 m/s, porosity levels range from 11.63% to 13.44%, water absorption by total immersion falls between 5.40% and 6.16%, and sorptivity ranges from 9.93 g/m2 to 13.99 g/m2. Furthermore, the addition of rubber and plastic waste causes large voids and cracks to form inside the concrete structure. These voids and cracks can increase the porosity of the concrete, which raises the rate of water absorption and lowers the ultrasonic pulse velocity, according to scanning electron microscopy (SEM) data. After assessing the data, it was determined that the numerical simulations for various factors such as ultrasonic pulse velocity, porosity, water absorption by total immersion, and water absorption by capillary exhibited strong correlation, with calculated coefficients R&sup2; near 1.
Optimal Treatment Methods for Anti-Tartar Management in Circulating Water Systems
Authors: Mazouz Kherouf 
Published: January 2025

Abstract
Utilizing seawater in industrial water systems leads to scale formation on heat exchange surfaces, reducing efficiency significantly. Even a 1 mm deposit causes a 30% decrease in effectiveness, raising cooling or condensation temperatures by 6°C and increasing electrical power consumption by 18%. Preventive measures include chemical treatments, which require careful balancing to avoid corrosion risks, and physical treatments like magnetic or electronic conditioners, which vary in efficacy. Water softening replaces metals with sodium ions but may increase mineral content, exacerbating scale buildup. Corrosion control is essential to counter metal degradation. Balancing prevention strategies is crucial. Research explores using Mediterranean seawater in cyclic systems to conserve freshwater and enhance coastal water availability. The aim is to find economically viable methods to stabilize cooling systems for both soft and saline water.

Published: January 2025

Abstract
The dual system buildings consisting of Unreinforced Masonry (URM) Shear Walls and Reinforced Concrete (RC) Frames are part of the existing buildings patrimony in Romania. Being a seismic zone, the qualitative evaluation of this type of structural system represents both a specific and a holistic approach. Thus, the in-depth knowledge of the initial situation of the building, including the level of degradation as well as the causes that produced these damages represents the present study. Also, notions such as: the level of degradation importance, the level of damage (destruction), the correction coefficient of the bending stiffness, the level of knowledge, the evaluation methodology are interpreted, in order to establish a score of the degree of seismic configuration of the lateral system and degree of structural damage. This information leads to the establishment of the seismic risk class of the analyzed building and to the establishment of the intervention works necessity.

The rights and obligations of the owner of the aggregator of information about goods and services in relations with the consumer
Authors: Chagina Elizaveta Mihailovna 
Published: January 2025

The development of digital technologies and the emergence of large Internet platforms that allow consumers to choose and purchase goods and services, aggregators of information about goods and (or) services, makes the issue of regulating the activities of these entities relevant precisely in terms of their interaction with consumers. It is no secret that when making a purchase and sale agreement or providing paid services through an information aggregator, the consumer does not interact directly with the seller or contractor, relying only on the information about the counterparty or the product (service) provided by the information aggregator, which inevitably raises the question of the role of the owner of such an aggregator in legal relations with consumers, his rights and obligations, as well as the limits of his liability for violation of consumer rights. The author of the work has chosen a formal legal method, as well as a method of analysis and interpretation of normative legal acts as the basis of the research methodology. As a result of the research, the author concludes that despite the fact that currently the legislation in the field of consumer protection contains a number of norms regulating the rights and obligations of the owner of the aggregator of information on goods and services in relations with the participation of consumer citizens, the current legal regulation in this area is not without gaps. Thus, attention is drawn to the fact that the existing limitation of liability of the owner of the aggregator of information about goods and services for providing the consumer with false information about the counterparty or about the product or service leads to a violation of the balance in his legal relations with the consumer and insufficient protection of the latter's rights. In this regard, the author makes suggestions for improving the legal regulation.

Published: January 2025

Objectives:
The distribution of ABO, Rhesus (Rh) (D, C, E, c, and e), and K antigens varies from one region or ethnic group to another. The objective of the study was to determine the prevalence of ABO, Rh phenotypes, and Kell antigens among pregnant women of Lelna ethnic group in Kebbi state, Northwest Nigeria.

Material and Methods:
One-hundred and ninety-six pregnant women, aged 18–42 years, were recruited for the study from the antenatal Clinic of General Hospital, Zuru, Kebbi State, between October 2021 and November 2022. ABO, Rh (D, C, E, c, and e), and K antigens were determined using standard techniques.

Results:
The study showed the prevalence of blood groups A, B, O, and AB as 20.9%, 13.3%, 64.3%, and 1.5%, respectively, while Rh (D)-positive and Rh (D)-negative individuals were 95.4% and 4.6%, respectively. The frequencies of C, E, c, e, and K were 15.3%, 14.3%, 14.3%, 20.9%, and 6.6%, respectively. However, cDe/cDe (RoRo) had the highest frequency of Rh phenotype of 70.4% while CDe/cDe (R1Ro) had the least frequency of Rh phenotype among Rh (D) positive pregnant women, but cde/cde (rr) phenotype had the highest prevalence among the Rh (D) negative pregnant women of 3.1%.

Conclusion:
The study has shown that blood group O and cDe/cDe (RoRo) were the most common ABO and Rh blood group phenotypes, respectively, among the pregnant women of the Lelna ethnic group in Kebbi state. This knowledge can serve as a guide to the blood bank in adjusting the bloodstock by blood type and assuring adequate blood supply to meet up with the demands of the patients and, most especially pregnant women to minimize or prevent blood transfusion reactions in the locality.
