Zasada tzw. "prawdy materialnej" i "prawdy formalnej" analiza logiczno-filozoficzna i przeglądowa
Authors: Łukowski Łukasz , Żukowski Bartosz
Published: October 2023

Concepts of material and formal truth have a long and well-grounded tradition in the doctrine of law. It seems, however, that they need some clarification and conceptualisation in purely philosophical and logical terms. In this paper, we propose such a theoretical analysis. These considerations are followed by a review of the key aspects of the current Polish legislation, which is written from the point of view of the conclusions reached through the first level of analysis.

Published: October 2023

Thoraco-abdominal aortic aneurysm (TAAA) open repair is a high-risk surgery further burdened with both mortality and morbidity. Despite numerous experimental endeavors and technical advancements, spinal cord ischemia (SCI) is still the most formidable morbidity to be resolved, irrespective of the open or endovascular surgical approach. It presents a spectrum of severity, ranging from temporary or permanent paraparesis to paraplegia with or without autonomic dysfunction. The timing of SCI occurrence is a crucial factor, with approximately 15% of cases manifesting intraoperatively, 50% within 48 h post-surgery, and the remaining 35% classified as late SCI, occurring more than 48 h after the procedure. The mechanism responsible for SCI is complex and multifactorial; hence, understanding its underlying pathophysiology is essential for its effective management. Over the last decade, strategies to enhance spinal cord perfusion and minimize the risk of SCI during TAAA open repair have been implemented. These include optimization of hemodynamics, hemoglobin levels, cardiac function, and cerebrospinal fluid pressure, ensuring collateral vascular network stability and distal aortic perfusion and intrathecal administration of drugs. A multimodal approach involving anesthesiologists and surgeons can lead to improved neurological recovery and a reduced incidence and severity of SCI.

Comparison of ultrasound-guided genicular block vs. intrathecal morphine for postoperative analgesia in patients undergoing knee arthroplasty: A randomised prospective study
Authors: Canakci Ebru , Coskun Ilker
Published: October 2023

Aim:  Total knee arthroplasty (TKA) is a major orthopedic surgical procedure often necessitating effective postoperative analgesia. This study aimed to compare the analgesic efficacy of ultrasound-guided genicular block (GB) and intrathecal morphine (ITM) in patients undergoing THA under spinal anesthesia.Method: A prospective, randomized, single-blind study was conducted at Ordu University Training and Research Hospital from October 1, 2022, to April 1, 2023. Eligible patients aged 18 to 90 undergoing knee surgery with spinal anesthesia were randomized into two groups: Group ITM received intrathecal morphine, while Group GB underwent ultrasound-guided triple genicular block. Pain scores, rescue opioid consumption, time to initial mobilization, and Modified Bromage Scale (MBS) scores were assessed at five time points (0, 2, 6, 12, and 24 hours) within the first 24 hours post-surgery.Results: At the 24-hour mark, cumulative tramadol consumption was significantly lower in Group ITM compared to Group GB (35.45±54.84 vs. 63.37±37.7 mg, respectively, p = 0.028). Group ITM also exhibited statistically lower Numeric Rating Scale (NRS) scores at 12 hours (p = 0.005) but had similar scores at other time points. Additionally, time to first ambulation and MBS scores were consistent across all intervals (p < 0.05).Conclusions: In patients undergoing knee arthroplasty with spinal anesthesia, those receiving ultrasound-guided genicular blocks demonstrated higher opioid consumption over a 24-hour period compared to those receiving intrathecal morphine. However, regarding postoperative pain scores, both groups exhibited similar outcomes. These findings provide valuable insights into the selection of postoperative analgesic modalities for TKA patients.

TOURISM GROWTH AS A DRIVER OF MIGRATION PATTERNS: EVIDENCE FROM CROATIA
Authors: Ivandić Ria , Ivandić Neven
Published: October 2023

Purpose – This research investigates to what extent local economic growth driven by tourism was able to prevent emigration from local areas. The relative economic prosperity of the Western Member States is considered to have had a large pull effect on immigrants following the enlargement of the EU to Central and Eastern European states. A similar pattern has been established in Croatia, where a mass exodus of the population has been recorded in the years following the 2013 EU Accession. Methodology – To do so, we use the newly released Population Census data from 2021, along with data from the earlier Census, to create a panel dataset of all municipalities and cities in Croatia and estimate the role of tourism. These data sources overcome the measurement errors in previously available annual migration data from the Ministry of Interior and allow for a more disaggregated analysis using detailed variables on the age and sex profile of citizens. We estimate a linear regression model using Ordinary Least Squares with the difference in population change as the dependent variable and measures of tourism development as the independent variable. Findings – We find evidence that the size of tourism is negatively associated with the size of emigration from the local area. We then investigate the mechanisms behind the relationship between local tourism growth and emigration, testing whether tourism is more correlated with emigration of younger or older individuals, men or women. Contribution – This paper is the first to shed light into the empirical nexus between tourism growth as the cause of the retention of population. Policy wise, it gives important insights into understanding how economic opportunities are key for individuals’ decision to emigrate that could be relevant for policymakers interested in ways to retain local populations. Finally, methodologically, to the best of our knowledge, it is the first research to explore migration patterns using the 2021 Census.

Authors: Skalska Teresa
Published: October 2023

Purpose – The aim of the article is to assess the significance and level of inconvenience of selected attributes of tourist services provided for people with various types of social exclusion, the disability among them. It may be helpful for understanding the possibility of separating customer groups and seeing their needs at particular stages of the supply chain in tourism (information, accommodation, transport, organization and intermediation). Methodology – The survey was conducted among disabled and seniors helped to identify quality gaps in the provision of tourism services, taking into account their complementarity and accessibility at every stage of the delivery. The empirical data were obtained as a result of a survey conducted with the use of the CAPI (Computer-Assisted Personal Interview) method among persons with disabilities (n=610). The survey aimed to acquire respondents’ opinions on the significance (importance) and individual inconvenience to the respondent of a number of services related to a tourism trip. The method of Importance-Performance Analysis (I.P.A) and basic measures of descriptive statistics were used to analyze empirical data. Findings – The survey results show how much the expectations of people with disabilities differ from the stereotyped perception of both the community itself and barriers to information services and participation in the tourism market. The important gap related to the widespread use of modern information technologies in tourism services was particularly highlighted. The results of the study will help to indicate to what extent the tourist experience of a disabled person and seniors affect the assessment of the significance and inconvenience of selected attributes of tourist services. It can point out stereotyped perception of restrictions and expectations. Contribution – The results of the author’s original research are mostly of practical and social character. They can be used by entrepreneurs to analyze the quality and reliability of services provided by their partners and the behavior and needs of the disabled people and seniors in tourism. They will also be useful for local and regional authorities responsible for ensuring the competitiveness and inclusiveness of tourism regions.

Authors: Dadić Fruk Lorena
Published: October 2023

Purpose – To fund their missions, non-profit organizations (NPOs) use a variety of fundraising activities such as applying for public funds (grants), contacting potential donors by phone, email, or through social networks; organizing various events; renting property, collecting membership fees, and selling their own products and services. The aim of this paper is to investigate whether there are any statistically significant differences between NPOs operating in Croatian coastal tourist destinations and NPOs operating in continental destinations with regard to selling products and services to raise funds. Methodology – For the purpose of obtaining answers to the research questions, primary research was conducted using an online structured questionnaire. Research in Croatian coastal tourist destinations was conducted from May to June 2018, while in continental tourist destinations from November 2019 to March 2020. The sample numbered 756 NPOs, and a total of 389 correctly completed questionnaires were returned. Findings – The results of the research show that almost all activities relating to selling products and providing services, with the exception of activities in organizing guided tours, are carried out more often by NPOs operating in Croatian coastal destinations. Activities relating to the organization of guided tours are more often carried out by NPOs operating in continental destinations. Contribution – The theoretical contribution of the paper show that the coastal NPO as a non- profit destination stakeholder led effective policy in the most cases but not in all. The paper’s practical contribution is that it provides the representatives of NPOs with a new approach about the activities of fundraising. Future research needs to be done to estimate the impact of NPOs on tourism sector, before fundraising strategies becomes widespread.

Hydration for Adult Patients with Nephrolithiasis: Specificities and Current Recommendations
Authors: Courbebaisse Marie , Travers Simon , Bouderlique Elise , Michon-Colin Arthur , Poli Laura , Baron Stéphanie , Prot-Bertoye Caroline
Published: October 2023

Nephrolithiasis affects around 10% of the population and is frequently associated with impaired dietary factors. The first one is insufficient fluid intake inducing reduced urine volume, urine supersaturation, and subsequently urinary lithiasis.
Kidneys regulate 24-hour urine volume, which, under physiological conditions, approximately reflect daily fluid intake.
Increasing fluid intake has a preventive effect on the risk of developing a first kidney stone (primary prevention) but also decreases the risk of stone recurrence (secondary prevention).
Current guidelines recommend increasing fluid intake at least at 2.5L /day to prevent stone formation, and even at 3.5-4L in some severe forms of nephrolithiasis (primary or enteric hyperoxaluria or cystinuria). Fluid intake must also be balanced between day and night, to avoid urinary supersaturation during the night. Patients should be informed and supported in this difficult process of increasing urine dilution, with practical ways and daily routines to increase their fluid intake. The liquid of choice is water, which should be chosen depending on its composition (such as calcium, bicarbonate or magnesium content). Finally, some additional advices have to be given to avoid some beverages such as those containing fructose or phosphoric acid, which are susceptible to increase the risk of nephrolithiasis.

Published: October 2023

It was of great practical significance to repair the toxicity of salt stress environment to soybean seedlings and maintain the balance between agricultural production and ecological environment in the Yellow River valley of China. ‘Xudou 20’ was used as the experimental material, a large-scale planting variety in the old Yellow River basin. Endophytes 131 and 137 isolated from soybean root nodule were taken as the research objects, and the soybean plants were cultivated by pot culture in intelligent artificial incubator. Salt stress group, bacteria suspension group and control group were set up to study the effects of inoculation treatments on the activities of superoxide dismutase (SOD) and catalase (CAT) of soybean seedlings under different NaCl stress. The results showed that when inoculated with endophyte 131 bacterial suspension and cultured for 14 days, the SOD activity was the highest (14.89 U•g−1•FW) at the salt concentration 50 mmol•L-1. When inoculated with 131 bacterial suspension (2:1) and cultured for 28 days, the SOD activity reached the highest (0.94 ug-1FW) at the salt concentration of 50 mmol•L-1, and the CAT activity amounted to the highest (1910 U•g−1•min−1). The 16S rDNA sequencing and phylogenetic analysis showed that the most similar strain of strain 137 was Bacillus cereus, and the most similar strain of strain 131 was Enterobacter ludwigii. Therefore, the activities of SOD and CAT in soybean seedlings inoculated with endophytes 131 and 137 increased at different degrees under salt stress, which could effectively alleviate the damage of salt stress environment to plants, and thus improve the stress resistance of plants.
Neural Networks-Based Approach for Detecting and Filtering Misleading Audio Segments for Classroom Automatic Transcription
Authors: Hewstone Jorge , Araya Roberto
Published: October 2023

Audio recording in classrooms is a common practice in educational research, with applications ranging from detecting classroom activities to analysing student behaviour. Previous research has employed neural networks for classroom activity detection and speaker role identification.
However, these recordings are often affected by background noise that can hinder further analysis, and the literature has only sought to identify noise with general filters and not specifically designed for classrooms. Although the use of high-end microphones and environmental monitoring can mitigate this problem, these solutions can be costly and potentially disruptive to the natural classroom environment.
In this context, we propose the development of a neural network model that can specifically detect and filter out background noise in classroom recordings. This model would allow the use of lower quality recordings without compromising analysis capability, thus facilitating data collection in natural educational environments and reducing the costs associated with high-end recording equipment.

Authors: Shestopalov Yury , Shakhverdiev Azizaga , Arefiev Sergey V.
Published: October 2023

The behaviour and bifurcations of solutions to three-dimensional (three-phase) quadratic polynomial dynamical systems (DSs) are considered. The integrability in elementary functions is proved for a class of autonomous polynomial DSs. The occurrence of bifurcations of the type twisted fold is discovered on the basis and within the frames of the elements of the developed DS qualitative theory. The discriminant criterion applied originally to two-phase quadratic polynomial DSs is extended to three-phase DSs investigated in terms of their coefficient matrices. Specific classes of D- and S-vectors are introduced and complete description of the symmetry relations inherent to the DS coefficient matrices is performed using the discriminant criterion.
AGPNet: Augmented Graph Pointpillars for Object Detection from Point Clouds
Authors: Wang Xiaohua , Liu Jian , Liao Zhonghe
Published: October 2023

In the realm of autonomous vehicle environment perception, the primary objective of point cloud target detection is to swiftly and accurately identify three-dimensional objects from point cloud data. To meet this requirement, the prevalent network architecture employed in the industry is the voxel-based PointPillars model. Nonetheless, this model faces challenges in maintaining detection accuracy when objects are obscured or diminutive in size. In response to this issue, we introduce AGPNet, a novel model that seamlessly integrates four key modules: Data Augmentation, Dynamic Graph CNN, Pillar Feature Net, and Detection Head (SSD). The Data Augmentation module enhances the adaptability of point cloud data to complex and ever-changing real-world environments. The Dynamic Graph CNN module endows the network structure with geometric features, which encapsulate not only the point itself but also its adjacent points. The Pillar Feature Net module translates three-dimensional point cloud data into pseudo-image data through the utilization of voxels. Subsequently, the Detection Head (SSD) module leverages this pseudo-image data to conduct target detection of three-dimensional objects. Our experiments, conducted on the KITTI dataset, demonstrate that our proposed method boosts object detection accuracy by 6-7 percentage points compared to the PointPillars model, while maintaining similar detection times.

On September 26, 2022, NASA's Double Asteroid Redirection Test (DART) mission successfully impacted Dimorphos, the natural satellite of the binary near-Earth asteroid (65803) Didymos. Numerical simulations of the impact provide a means to explore target surface material properties and structures, consistent with the observed momentum deflection efficiency, ejecta cone geometry, and ejected mass. Our simulation that best matches observations indicates that Dimorphos is weak (less than a few Pa), similar to asteroids (162173) Ryugu and (101955) Bennu. We find that a bulk density of Dimorphos, ρB, lower than ≈ 2400 kg/m3, and a low volume fraction of boulders (≲ 40 vol%) on the surface and in the shallow subsurface, are consistent with measured data from the DART experiment. These findings suggest Dimorphos is a rubble pile that might have formed through rotational mass shedding and re-accumulation from Didymos. Our simulations indicate that the DART impact caused global deformation and resurfacing of Dimorphos. ESA's upcoming Hera mission may find a re-shaped asteroid, rather than a well-defined crater.

This study focuses on the environmental conditions of the Mahanadi Estuary near Paradeep Harbor and the adjacent sea. Data collected from May 2013 to April 2020 from 32 GPS fixed stations was analyzed to assess the water quality in different zones (estuarine, mixed zone, mixed zone south, and mixed zone north) of study area. Parameters such as pH, SST, TSS, nitrite, phosphate, silicate, TOC, chlorophyll, fecal coliform, and heavy metals were used to estimate the Water Quality Index (WQI) for each zone. The study found a deterioration (>30%)in the overall water quality of the Mahanadi Estuary from 2013 to 2020, potentially attributed to river inflows, port activities, and industrial outflows in to the coastal ecosystem. Seasonal variations in temperature, salinity, turbidity, nitrite, nitrate, and ammonia were observed. The water quality showed a deteriorating trend in estuarine, mixed zone, mixed zone south, and mixed zone north. Based on the water quality indices, the ecosystem shows moderate levels of stress. The degraded water quality highlights the need for a targeted mitigation plan to reduce external pressures and enhance the overall ecosystem quality.

Hydrogen-centered electrochemical technologies play a vital role in sustainable energy conversion and storage. One of the challenges in achieving cheap hydrogen is to bridge the gap between advanced electrocatalysts and highly effective electrodes. Here, we synthesized BaRuO3 in four polymorphs with distinct RuO6 connections to rationalize the impact of crystal structure feature on transferable alkaline hydrogen evolution activity. The 9R-BaRuO3 displays the best hydrogen evolution reaction activity and stability in alkaline solution with a small Tafel slope of 30 mV dec-1 and a low overpotential of η10 < 51 mV, which is comparable to Pt/C and superior to the most highly efficient ruthenium-based oxide hydrogen evolution catalysts reported to date. Such performance is ascribed to its high intrinsic activity that is delivered by the d-d interaction and optimal intermediate adsorption. More importantly, 9R-BaRuO3 can be easily synthesized on a large scale as demonstrated by the 9R-BaRuO3-500 g sample in this study. The high intrinsic activity and micron size of 9R-BaRuO3 powders enable a successful performance transfer from a lab-based three-electrode system to a commercial alkaline electrolyser operated under industrial conditions. The findings presented here not only demonstrate a robust and efficient HER electrocatalyst for practical electrolysers, but also emphasize the effect of structural features in the design of advanced electrocatalysts.

Background: Combined oral contraceptives (COCs) are reliable medications used as a contraception method. One of the most common reasons for discontinuing COCs is their association with negative mood disorders. Studies have confirmed the anti-anxiety and mood-stabilizing effects of lavender.
This study was conducted to investigate the effects of lavender essential oil (LEO) on mood disorders associated with the use of COCs.
Methods: This triple-blinded clinical trial was conducted on 60 married women (aged 15-49 years old) who were consumers of COCs, referring to 26 health centers in Tabriz, Iran. The participants were randomly assigned to either the intervention (consuming one gelatin capsule containing 80 mg LEO daily) or control (consuming one placebo capsule daily) group. The intervention continued for 56 days. Scores for Positive and negative were determined using the Positive and Negative Affect Schedule (PANAS) questionnaire, and stress, depression, anxiety were measured using the DASS-21 questionnaire on day’s 28th and 56th post-intervention. Data analysis was conducted using the t-test and ANOVA with the RM model and a p-value of < 0.05 was considered significant for all analyses.
Results: A statistically significant difference was observed in mood disorders, stress, and depression between women receiving LEO or placebo. The consumption of LEO increased the positive mood on day 28 [MD (95% CI): 4.5 (2.1 to 7.0), p=0.001] and day 56 [5.9 (3.4 to 8.3), p<0.001] while decreased the negative mood on day 28 [MD (95% CI): -3.5 (-5.3 to -1.3), p<0.001] and day 56 [-4.3 (-6.3 to -2.2), p<0.001] , stress on day 28 [MD (95% CI): -4.9 (-7.1 to -2.8), p=0.001] and day 56 [-5.3 (-7.6 to -3.1), p<0. 001], and depression on day 28 [MD (95% CI): -3.0 (-4.9 to 1.1), p=0.003] and day 56 [-3.1 (-5.0 to 1.2), p=0.002]. There was no statistically significant difference between the two groups in terms of anxiety.
Conclusions: The consumption of LEO with COCs improved mood disorders and reduced stress and depression. It is expected that appropriate counseling and education should be offered to women using COCs regarding the possibility of mood changes, providing appropriate solutions, including the simultaneous use of LEO.

Temporal overlapping effect in pump-probe technique on the Rhodamine 6G with addition copper nanoparticle
Authors: khalid Saad
Published: October 2023

This study took place utilizing the laser "Pump-Probe" probe technique to investigate the properties of a rhodamine 6G laser dye. 532 nm wavelength laser was employed for excitation of the dye "pumping", while another laser with a wavelength of 657 nm was utilized for sensitization "probe". A copper nanomaterial with an average size of 43 nm has been added to the system. The green laser pulse width was modulated at various percentages, including 5%, 10%, 20%, 30%, 40%, and 50% of the original pulse width. The pulse utilized for the pumping process was divided into two components, one of the tow pulse was directed towards the dye, while optical path of the other component was altered by employing multiple mirrors, the modification in the optical path was implemented in order to establish an accurate delay time between the two pulses and control their overlap by extending the duration of the laser pulse. The transmittance laser intensity was determined both before and after the addition of the nanomaterial. Additionally, (FWHM) of the output laser pulse was computed. The wavelength of the output laser pulse was also determined through calculation. The study findings demonstrated a discernible impact resulting from the alteration of laser pulse width as well as the influence of the nanomaterial on the intensity and optical characteristics of the dye. This study is a component of a series of research endeavors focused on comprehending the interplay between nanomaterials and laser dyes as well as the resultant impact of these interactions on the characteristics of laser dyes.

Stroke is a neurologic disease caused by sudden disturbance of cerebral blood circulation. Studies have shown that patients with psoriatic disease (PsD) (psoriasis and psoriatic arthritis (PsA)) may have an increased risk of stroke, but the results are inconsistent. The aim of this study was to provide an updated meta-analysis about the risk of stroke in PsD. Electronic databases was searched to identify relevant studies. Random-effects model was used to analyze the risk of stroke in patients with PsD. Subgroup analyses were conducted to identify sources of heterogeneity between studies and further explore risk relationships. This meta-analysis found an increased risk of stroke in patients with PsD, with the pooled relative risk (RR) of 1.23 (95% confidence interval (CI): 1.20-1.27). In subgroup analysis stratified by severity of psoriasis, the risk of stroke was higher in severe (RR = 1.42, 95% CI: 1.22-1.65) than in mild psoriasis (RR = 1.12, 95% CI: 1.03-1.21). In the subgroup analysis of stroke type, PsD patients had a greater risk of ischemic (RR = 1.49, 95% CI: 1.26-1.76) than hemorrhagic stroke (RR = 1.30, 95% CI: 0.80-2.11). The RRs of stroke in PsD patients from Asia, Europe, and the United States were 1.26 (95% CI: 1.08-1.46), 1.19 (95% CI: 1.08-1.31), and 1.28 (95% CI: 0.75-2.17), respectively. Patients with PsD have an increased risk of stroke. Severe psoriasis patients may have a higher risk of stroke than mild.

ATP is a universal energy currency that is essential for life. ATP generation based on the degradation of L-arginine can be used for the bottom-up construction of synthetic cells. In an earlier design of this pathway, a relatively slow L-arginine/L-ornithine antiporter limited ATP production. After testing homologous proteins, we now implement an antiporter (ArcD from Lactobacillus sakei) with improved transport kinetics, leading to faster ATP recycling in organelle-like vesicles. Furthermore, we exploit the L-arginine-dependent ATP formation for the synthesis and export of glycerol-3-phosphate with complete recycling of waste products, ensuring sustainable production of building blocks. The exported glycerol-3-phosphate from the feeding vesicles serves as a precursor for the biosynthesis of phospholipids in utilizer vesicles, which provides the basis for the expansion of the cell membrane. We thus develop an out-of-equilibrium metabolic network for ATP generation and couple metabolic energy production to lipid synthesis in an organelle-like system, inspired by compartmentalization in eukaryotic cells.
CK2α-mediated phosphorylation of GRP94 facilitates the metastatic cascade in triple-negative breast cancer

Published: October 2023

Distant metastasis is a significant hallmark affecting to the high death rate of patients with triple-negative breast cancer (TNBC). Thus, it is crucial to identify and develop new therapeutic strategies to hinder cancer metastasis. While emerging studies have hinted a pivotal role of glucose-regulated protein 94 (GRP94) in tumorigenesis, the exact biological functions and molecular mechanisms of GRP94 in modulating cancer metastasis remain to be elucidated. Our study demonstrated an increased expression of GRP94 in TNBC correlated with metastatic progression and unfavorable prognosis in patients. Functionally, we identified that GRP94 depletion significantly diminished TNBC tumorigenesis and subsequent lung metastasis. In contrast, GRP94 overexpression exacerbated the invasiveness, migration, and lung metastasis of non-TNBC cells. Mechanistically, we found that casein kinase 2 alpha (CK2α) active in advanced breast cancer phosphorylated GRP94 at a conserved serine 306 (S306) residue. This phosphorylation increased the stability of GRP94 and enhanced its interaction with LRP6, leading to activation of canonical Wnt signaling. From a therapeutic standpoint, we found that benzamidine, a novel CK2α inhibitor, effectively suppressed GRP94 phosphorylation, LRP6 stabilization, and metastasis of TNBC. Our results point to the critical role of CK2α-mediated GRP94 phosphorylation in TNBC metastasis through activation of Wnt signaling, highlighting GRP94 as a therapeutic target to impede TNBC metastasis.
