Published: July 2023

Grupa młodych klientów jako podmiot rozważań badawczych jest interesującą poznawczo grupą społeczną. Młodzi klienci stanowią istotną siłę nabywczą. Atrakcyjność tego segmentu wynika z per- spektywicznego punktu widzenia banków, w ramach którego młodzi klienci staną się w niedalekiej przyszłości zasobnymi dorosłymi, korzystającymi z usług sektora bankowego. Celem artykułu bę- dzie przedstawienie i ocena rachunków bankowych oferowanych młodym klientom. Autorki będą poszukiwały odpowiedzi na pytania badawcze, jak wygląda oferta rachunków bankowych dedy- kowanych młodym klientom; czy jest ona dostosowana do potrzeb tej grupy i czy jest zróżnicowa- na. W części empirycznej, egzemplifikującej zagadnienie teoretyczne rachunków bankowych dla młodych klientów odwołano się do stanu z kwietnia 2021 roku. Z analizy ofert bankowych wynika, że rachunki dedykowane młodym klientom są skierowane zazwyczaj do grupy wiekowej w prze- dziale 18–26 lat. Chociaż zdarzają się produkty adresowane do osób w wieku 13–24 lat lub do 30. roku życia. Analizowane produkty to darmowe rachunki osobiste, z dostępem do programów rabatowych i promocji powiązanych z bankami partnerów biznesowych. Oferta jest zróżnicowana i młodzi klienci mogą w niej znaleźć rozwiązania dopasowane do ich indywidualnych potrzeb.

La fraternité en droit civil contemporain
Authors: Wagoue Tongoue Diane Carlyne
Published: July 2023

La fraternité s’entend généralement comme la loi de l’amour. Dépassant désormais le cadre familial qui l’a vu naître, elle est souvent perçue telle l’une des inventions de l’hypocrisie sociale. Pourtant, sa dimension altruiste lui donne toute sa fertilité. L’ambition de la réflexion de l’auteure est de démontrer que la fraternité, sans laquelle tous les avantages publics et individuels seraient douteux et précaires, est un objectif structurant de l’ordre juridique en droit civil. Indispensable pour le respect de la dignité de la personne, elle permet une humanisation des relations sociales. Elle apparaît aujourd’hui en tant que matrice des principes gouvernant les relations entre les individus. Cette reconnaissance contemporaine de sa capacité à légitimer des droits et des obligations juridiquement contraignantes favorise un dépassement de son essence facultative pour l’imposer dans de nombreux rapports sociaux. Ainsi, à côté d’une fraternité généralement consentie par les particuliers, il existe de nos jours une fraternité imposée par la loi.

Authors: Goncharov Vitalii Viktorovich
Published: July 2023

This article is devoted to the analysis of modern problems and prospects for the development of the institute of public control over representative bodies of local self-government in the Russian Federation. This topic is of particular relevance due to the fact that these public authorities are directly elected by the people. The subject of the analysis is the relevant provisions of the legislation of Russia devoted to the consolidation of the mechanism of organization and implementation of public control over the activities, acts and decisions of representative bodies of local self-government and the practice of their application. General and private scientific methods were used in the work, in particular, dialectical, logical, historical-legal, formal-legal, comparative-legal. The author examines the role and place of representative bodies of local self-government in the system of public authorities in the Russian Federation. The paper identifies and formalizes the main problems that hinder the organization and implementation of public control over representative bodies of local self-government in the Russian Federation, develops and justifies a system of measures for their optimal resolution. The issues of development in the scientific legal doctrine and introduction of new forms, methods, principles and types of public control measures in relation to representative bodies of local self-government in the Russian Federation need further scientific understanding.

The superlattices composed of polar/polar perovskites have two-dimensional electron gas (2DEG) at the interface, which has broad applications in nano devices, super sensitive sensor devices, high electron mobility transistor, etc. Tuning the electronic properties of the 2DEG at the interface perovskite superlattice, such as the coupling between strain gradient and the electronic properties of the 2DEG in correlated electronic systems, is of great significance. In this paper, the properties of (LaAlO3)4.5/(KNbO3)8.5 superlattice, which is composed of KNbO3 and LaAlO3, are systematically investigated through first-principles density functional theory calculations. The band structure of (LaAlO3)4.5/(KNbO3)8.5 superlattice exhibits 2DEG at the interface, which is consistent with the result in the literature. The band structure, density of states, magnetic moments and carrier concentration at the interface are fully investigated by using compressive gradient and tensile strain gradient, respectively. The results show that compressive strain gradient can effectively reduce the 2DEG concentration at the interface. When the compressive strain gradient coefficient reaches 12%, the 2DEG concentration decreases by 76.4%, and the interface magnetic moment disappears. The total magnetic moment of the superlattice decreases by 88.44%. When the tensile strain gradient is 12%, the electron gas concentration at the interface is increased by about 23.9%, and the interface magnetic moment is reduced by about 90.7%. At the same time, an obvious magnetic moment appears in the layer near the interface. Hence, the strain gradient can be a new approach to regulating the electron gas concentration at interface of perovskite superlattice. The tensile strain gradient increases the electron gas concentration at the interface, while the compressive strain gradient reduces the electron gas concentration. Therefore, it opens up a new way to exploring the regulation of high-performance spin polarized carrier gas at the oxide interface.

The electro-optical properties of polymer dispersed liquid crystal film vary with liquid crystal content and externally applied electric field, but the analysis of the film morphology cannot directly reflect the mechanism of electro-optical properties. Therefore, the polymer dispersed liquid crystal film prepared by blending liquid crystal material E7 and photopolymer NOA65 is used. Herein, the dielectric polarization regulated electro-optical properties and their related mechanisms under different liquid crystal content and electric fields are revealed. The results show that in a frequency range of 10–1–106 Hz, the film exhibits three relaxation processes respectively at low frequency, medium frequency and high frequency, which are generated by thermionic polarization, interfacial polarization and orientation polarization. According to the Arrhenius equation, the activation energy values of such polarization processes are calculated. It is found that with the increase of liquid crystal content, the activation energy of orientation polarization decreases from 0.88 eV to 0.83 eV, leading the threshold field strength and the saturation field strength of the diversion of liquid crystal molecule to decrease. Thermionic polarization under DC electric field forms an internal electric field, which causes the threshold field strength and saturation field strength to increase greatly, as compared with the scenarios under AC electric field. Such a thermionic polarization also leads the polarization relaxation time to increase, resulting in the extension of response time. This study is of guiding significance in further analyzing and improving the electro-optical properties of polymer dispersed liquid crystal films.
Study on the Performance Certification for Underground Buried Fire Hydrants using Water Sources
Authors: Han Yong-Taek
Published: July 2023

This study reviews and evaluates technical standards of “underground fire hydrants”,that are installed in places vulnerable to fires, such as traditional markets and doss houses in Korea, and that are easily used by fire-fighters as the first response to fires. In the future, this is expected to be a fire-fighting facility that can be used stably using a water source without additional equipment such as a pressurized water transport device or electricity that is required to be installed in a fire prevention reinforcement district. We reached the following technical conclusions regarding this facility. Test items to review the technical standards as a fire-fighting facility include the buoyancy and drainage test, opening and closing control test, edge sharpness test, water resistance test, material test, salt spray test, rubber material test, static load test, impact test, internal pressure test, storage device strength test, photo-luminescence labeling test, and labeling. As a result of reviewing the technical standards of the aforementioned study, the “underground buried fire-fighting hydrant” was not assumed to be applied directly to the installation site, but a procedure for establishing technical standards and performance inspection were suggested to be necessary.

Authors: Thomas Reji Kurien , Bose Satyam Khagen
Published: July 2023

The implementation of agronomic activities, based on the use of biostimulants, is an important element of agroecological practices. Therefore, a comprehensive field trial was carried out to evaluate the potential of biostimulants in growth promotion across four districts of Maharashtra (Jalna, Ahmednagar, Aurangabad and Nasik). The study aimed to evaluate the candidacy of selected biostimulants in improving onion (Allium cepa L.) extracted from proprietary technology involving adaptive molecular re-engineering for plant growth biostimulants category. Three biostimulants were preliminary analyzed for their nutritional content. Compositional analysis revealed the presence of several macro, micronutrients as well as humic, fulvic acid. The concentration of humic and fulvic acid in sediment extract were ranged from 34-38 and 10.5-10.8 g/100g respectively. The organic carbon, total nitrogen, phosphorus, and ash contents ranged between 54-57,0.4-0.6, 0.3-0.4, and 3.3-7.2% respectively. Ash and total nitrogen content were the same for the extract 0.2% and 7.8% respectively. Onion crops were treated in three different modes, seed treatment, root drenching and foliar spray. Biostimulants were applied in combination with three different levels of chemical fertilizer 50%, 75%, and 100% RDF and compared with Control (100%RDF without biostimulants). Several qualitative and quantitative parameters such as firmness, pungency, neck diameter, bulb diameter, and yield were analysed.

It was observed that all three biostimulants (Asaava, Somrith, and Yuvaani) significantly(P<0.001) affected all the measured plant traits. In addition to this, overall, we found excess chemical fertilizer imposed adverse effect on plant growth parameters. Moreover, it was concluded that with seed treatment followed by root drenching and foliar spray and optimized dosage scheduling, yield can be further improved. The best effect in overall growth and yield potential of the plants were noticed in Asaava treated plants.

Therefore, the aim of this phenomenal study is to establish the database system development of mental health care for the elderly during the COVID-19 public sentiment by using a geographic information system (GIS) to create a model database system.

Materials and Methods: A cross-sectional questionnaire was conducted by an elderly survey using a four-stage stratified random sampling to select 1,647 respondents aged 60 and over from the six subdistrict health promotion hospitals in four provinces, respectively. Descriptive statistics and stepwise multiple regression were used to analyze the data.

Results: The majority of the respondents were female (64.80%), aged 60–65 years (31.90%), and Buddhist (99.60%). Marital status: mostly married, live as a couple, or as a married couple (49.2%); level of education: mostly primary school (4th grade; 54.7%); not working (60.80%); average monthly income less than 1,000 baht (31.2%); with income sources, mostly from pensions (80.6%); income received is mostly inadequate (44.2%); and the majority had chronic diseases (58.8%), with mostly moderate health conditions in the last 6 months (44.3%). Significant factors affecting mental health problems or associated with stress in the elderly during the COVID-19 period were: participation in religious activities; daily activities (ability to perform basic daily activities); social support (from family, relatives, and friends); income; and anxiety during COVID-19. All of these factors could together predict the preventive behavior against mental health problems in the elderly during the COVID-19 period.

Conclusion: Based on the presented results, interdisciplinary healthcare teams should consider social support and access to healthcare when developing interventions for encouraging and promoting health outcomes in order to improve physical and psychological COVID-19 preventive behaviors and for the government in terms of increasing family income, particularly the oldest pension among elderly people during the COVID-19 pandemic.

Shisha smoke is becoming more prominent among adolescent which is known to be carcinogenic posing a serious threat to public health as well as the risk of pathogenic bacteria associated with the mouthpiece. This research is carried out to determine the prevalence and antibiogram of bacteria associated with mouthpiece of shisha equipment in Port Harcourt metropolis. A total of twenty (20) mouthpiece of shisha equipment were swabbed using sterile swab sticks and samples subjected to standard microbiological technique as well as standard plate count, culturing, identification and antibiotic susceptibility pattern using Kirby Bauer Disk diffusion method.  The total heterotrophic bacteria count ranged between 2.0±1.5 ×103 to 6.5±5.3 ×103 CFU/ml) Borokiri township and Ogunabali respectively. The total Staphylococcal count ranged from 1.6±0.5 ×102 CFU/ml to 3.3±0.3 ×102 CFU/ml in Ogunabali township and Borokiri sandfield respectively. A total of fourteen (14) bacteria isolates were identified belonging to the following genera; Staphylococcus spp, Klebsiella spp, Bacillus spp, Pseudomonas spp, Micrococcus spp and Lactobacillus spp. The prevalence of the bacteria indicated that Staphylococcus had the highest occurrence (28.57%), followed by Pseudomonas spp (7.07%), having the least prevalence across the locations. The Antimicrobial sensitivity testing results shows that Staphylococcus spp Bacillus spp and Micrococcus spp was more susceptible to Erythromycin, Gentamicin and Ofloxacin (100%) and resistant to Augmentin, Cefuroxime, Cloxacillin, Cefuroxime and Ceftazidime (100%). Lactobacillus spp, Pseudomonas spp and Klebsiella spp were more susceptible to Ciprofloxacin and Ofloxacin (100%) and resistant to Gentamicin, Nitrofurantoin, Ceftazidime, Cefuroxime, Augmentin and Cefixime (100%). These bacteria isolated are mostly pathogenic and may result in an increase in health issues as a result of non-hygienic protocol used during using mouth to mouth smoking with the shisha equipment. Medical personnel should enlighten the public especially the adolescent about the risks involved in smoking Shisha.

The study examined the disaster rehabilitation and restoration program towards oil spill impacted communities in selected states in Niger Delta Region, Nigeria. The study was carried  out from six (6) LGAs from three (3) states, that is, Akwa Ibom, Bayelsa and Delta while questionnaire was administered among 400 respondents with return rate of 94% amounting to 375 valid questionnaires. The returned questionnaires were analysed using descriptive statistics and ANOVA for the study hypotheses. The outcome of the study indicated that repair of damaged community infrastructure (31.7%) and community arrest of the vandals (27.5%) are the most adopted disaster rehabilitation practices while application of fertilizer to improve the soil quality (35.2%) as the major restoration practices. Statistically, there was no significant difference in various rehabilitation programs among selected communities (where p > 0.05, p= 0.336); however, restoration programs showed a significant different among the selected community (where p > 0.05, p= 0.003). Deployment of capable hands for post disaster activities and stricter monitoring of activities during and after remediation, to ensure that the activities they have implemented are in accordance with regulatory standards was recommended.

Mortality from vmelanoma is associated with metastatic disease, but the mechanisms leading to spreading of the cancer cells remain obscure. Spatial profiling revealed that melanoma is characterized by a high degree of heterogeneity, which is established by the ability of melanoma cells to switch between different phenotypical stages. This plasticity, likely a heritage from embryonic pathways, accounts for a relevant part of the metastatic potential of these lesions, and requires the rapid and efficient reorganization of the transcriptional landscape of melanoma cells. A large part of the non‐coding genome cooperates to control gene expression, specifically through the activity of enhancers (ENHs). In this study, we aimed to identify ex vivo the network of active ENHs and to outline their cooperative interactions in supporting transcriptional adaptation during melanoma metastatic progression. We conducted a genome‐wide analysis to map active ENHs distribution in a retrospective cohort of 39 melanoma patients, comparing the profiles obtained in primary (N = 19) and metastatic (N = 20) melanoma lesions. Unsupervised clustering showed that the profile for acetylated histone H3 at lysine 27 (H3K27ac) efficiently segregates lesions into three different clusters corresponding to progressive stages of the disease. We reconstructed the map of super‐ENHs (SEs) and cooperative ENHs that associate with metastatic progression in melanoma, which showed that cooperation among regulatory elements is a mandatory requirement for transcriptional plasticity. We also showed that these elements carry out specialized and non‐redundant functions, and indicated the existence of a hierarchical organization, with SEs on top as masterminds of the entire transcriptional program and classical ENHs as executors. By providing an innovative vision of how the chromatin landscape of melanoma works during metastatic spreading, our data also point out the need to integrate functional profiling in the analysis of cancer lesions to increase definition and improve interpretation of tumor heterogeneity.

Published: July 2023

Purpose

We validate the routine use of a two‐dimensional (2D) diode matrix for patient specific pre‐treatment verification for Cyberknife (CK) stereotactic radiosurgery and to compare it with film dosimetry.

Materials and method

A total of 46 patients were selected according to the most frequent diseases treated at our institution with the CK system, that is, brain metastases, meningiomas, spine metastases, and prostate tumors. All cases were evaluated with GAFChromic EBT‐3 films and SRS MapCHECK for Fixed cone, IRIS, and MLC collimators of the CK.

Results

The highest mean passing rate was observed for the SRS MapCHECK system compared to films. In order to assess if the two techniques provide statistically different results, a Wilcoxon Signed‐Rank non‐parametric test was performed (p < 0.05) and we found gamma values significantly lower for EBT‐3 films with respect to the SRS MapCHECK. We noticed a moderately significant association between the two techniques using Spearman's rank correlation coefficient (rs > 0.4). We also performed the Bland–Altman statistical method: less than 5% of the differences resulted outside the range (mean ± 1.96 × SD), so the two methods can be considered interchangeable within the combined inaccuracy.

Conclusions

The use of SRS MapCHECK for CK patient specific quality assurance (QA) is feasible for a variety of clinical districts and could be reliably used as a replacement for radiochromic films.

In March 2020, the Belgian government ordered a complete lockdown as an attempt to decrease the progression of the COVID‐19. The aim of the present study was to examine lockdown‐related changes in psycho‐affective states as well as their relations with experiential diversity and autobiographical memory. A total of 186 Belgian citizens completed an online survey assessing lockdown‐related changes in various dimensions: work, leisure activities, affective state, sleep quality, fatigue, and autobiographical memory. Results revealed that well‐being during the lockdown was related to changes in experiential diversity and to the richness of participants' memories. Moreover, the content and the phenomenology of memories were more negative when memories pertained to the lockdown situation. These findings provide new evidence that mental well‐being of Belgian citizens during the first lockdown was related to how pandemic‐related sanitary constraints affected the diversity of activities that they could undertake.
Strengthening Mechanisms in Bulk FeCoCrNiAlx (x=0, 0.5, 1.0) High‐Entropy Alloys Fabricated by Laser Melting Deposition

Herein, FeCoCrNiAl
x
(x = 0, 0.5, 1.0) high‐entropy alloys (HEAs) are fabricated by the laser melting deposition (LMD) technique. With the increase of Al content, the LMD‐ed microstructure transitions from a single face‐centered cubic (FCC) phase to a dual‐phase structure containing a small amount of body‐centered cubic (BCC) phase (5.3%), and the proportion of the final BCC phase increases significantly to 98.2%. In addition to the compression tests, four strengthening models are used to evaluate the theoretical strength of the three alloys. The addition of Al element as grain refiner can improve the ultimate compressive strength of HEAs; however, the yield strength and plasticity do not improve, as theoretically expected. The FCC phase with more slip systems leads to higher plasticity in the LMD‐ed FeCoCrNi HEA but results in lower yield strength. The LMD‐ed FeCoCrNiAl0.5 HEA exhibits the best combination of strength and plasticity. Therefore, to meet the required service requirements, the content of Al in the FeCoCrNiAl
x
HEA should be carefully controlled under the premise of considering the actual working conditions.
A pH‐Cascaded DNA Hydrogel Mediated by Reconfigurable A‐motif Duplex, i‐Motif Quadruplex, and T·A‐T Triplex Structures
Authors: Hu Yuwei , Ke Yujie , Willner Itamar
Published: July 2023

Governed by pH‐configurable A‐motif, i‐motif and T·A‐T triplex configurations, a cascaded DNA hydrogel subjecting to diverse pH values is presented. Under highly acidic conditions (pH 1.1), N1 protonation of adenine (pKa 3.5) in A‐strands generates AH+‐H+A units, resulting in a parallel A‐motif duplex crosslinked hydrogel. Under mild acid conditions (pH 5.2), the dissociation of A‐motif duplex into single A‐strands occurs due to the deprotonation of adenine, while N3 protonation of cytosine (pKa 6.5) in C‐strands creates hemi‐protonated C:C+ units, resulting in i‐motif bridged hydrogel. At neutral pH (pH 7.2), deprotonation of cytosine separates i‐motif crosslinkers. Simultaneously, the addition of auxiliary T‐strands results in the N3 protonation of thymine (pKa 10), generating T·A‐T triplex stabilized hydrogel. Under mildly alkaline conditions (pH 10.2), T·A‐T triplex separates into single T‐stands and A‐T duplex, resulting in the disassembly of DNA hydrogel. Therefore, a stepwise pH‐cascaded DNA hydrogel dictates the formation of structures following the pH steps 1.1 → 5.2 → 7.2 → 10.2 where pH‐triggered DNA secondary structures, including A‐motif, i‐motif and T·A‐T triplex, stabilize the hydrogel. The study advances DNA hydrogels from single pH‐responsiveness to multiple cascaded pH values, which opens up new possibilities for the development of smart hydrogels capable of adapting to various environmental conditions.
