Abstract
This study examines the stability of double-diffusive convection in a Kuvshiniski viscoelastic nanofluid, in which the fluid is affected by two fields (such as temperature and salinity) that influence its density. The classical Fick’s law, which assumes an immediate response of temperature to the heat flux gradient, is not entirely correct because it suggests an instantaneous reaction at all points, which is not entirely accurate since information propagates at a finite speed. This shortcoming of Fick’s law leads us to consider the Maxwell–Cattaneo effect (MC effect). Thus, our research focuses on Maxwell–Cattaneo double-diffusive convection in a horizontal layer of a porous medium saturated with viscoelastic nanofluid. Here, the fluid’s small dimensions result in its relaxation time being comparable to its thermal diffusion time, necessitating the use of the Maxwell–Cattaneo relationship. The behavior of viscoelastic nanofluids is described by a constitutive equation of the Kuvshiniski kind, and for the porous medium, Brinkman–Darcy model is considered. The nanofluid model includes the effects of Brownian diffusion and thermophoresis, with the assumption that the flux of the nanoparticle volume fraction is zero at the isothermal boundaries. The framework of linear and nonlinear stability theory leads the analysis. By applying linear stability theory with the help of normal mode technique, the conditions for the occurrence of both stationary and oscillatory convective motions are found in terms of a critical thermal Rayleigh number. The Kuvshiniski viscoelastic fluid exhibits Newtonian behavior in a state of stationary convection. We have discussed two cases for oscillatory convection that are when (i) Maxwell–Cattaneo coefficient for temperature (C

T
) = 0 and (ii) Maxwell–Cattaneo coefficient for salinity (C

C
) = 0. Convective heat and mass transfers are determined using a weakly nonlinear stability analysis. The effects of various factors on oscillatory and stationary states as well as the mass and heat transport are depicted graphically. It is found that with increase in the value of Kuvshiniski parameter F, thermal Rayleigh number Ra also increases for both cases C

and thermosolutal Lewis number Ls for both stationary as well as oscillatory convection. With increase in the value of Darcy number Da, an interesting pattern can be seen. For stationary convection, Ra increases with Da, but it has reverse effect on oscillatory convection (for both the cases). Streamlines, isotherms, and isohalines are also examined.
Regulation of Lithuania and Czechoslovakia trade relations: Negotiations and agreements in 1931-1939
Authors: Bukelevičiūtė Dalia 
Published: October 2024

The world great economic depression had influence on Lithuanian economics only in 1931, and then in Czechoslovakia became aware of its negative results earlier. In 1931 the highest possible negative trade balance for Lithuania was a result of great economic depression and the difference between import and export of goods, i.e., 19 mln. Lt. In 1932 in Lithuania was discussed the question of balance decreasing and searching for a new market for Lithuanian agriculture products in Czechoslovakia. At the period of great depression, Czechoslovakia introduced quotas for butter, pigs, eggs, fats, and geese. The quotas were introduced for the products that Lithuania was interested in exporting and to decrease the trade balance with Czechoslovakia. In 1932, Lithuanian representative J. Aukštuolis went to Prague. He had to search for new markets for Lithuanian products and to find contacts with Czechoslovakian trade people and official persons. The official persons of Czechoslovakia didn’t want to give licenses for Lithuanian agricultural products because they wanted to protect their market. In 1932, in autumn, in Prague after long discussions began negotiations between Lithuanian and Czechoslovakian delegations. The goal of the negotiation was to determine quotas for Lithuania. This negotiation was sharp and serious, but the Lithuanian delegation got quotas for some agricultural products. Since 1932 it was the tradition that the Lithuanian delegation went to Prague and negotiated with Czechoslovakia for quota determination. In 1936 and 1937, quotas were determined by the intermediation of embassies. Czechoslovakia didn’t want to determine quotas for Lithuania because it was afraid of other states' interests. The Lithuanian delegation was satisfied with the negotiation results only in 1932 and in 1934. In 1932-1937, the Czechoslovakian delegation didn’t agree to sign an agreement with Lithuania. All negotiations finished only in oral agreement. Since 1932 Lithuania began to limit imports, and it influenced Czechoslovakia's interests to export textile products. In 1937, the trade balance was active for Lithuania. Czechoslovakia began to review the trade perspectives with Lithuania because of the change in trade relations. In 1938 and 1939, official persons of Lithuania and Czechoslovakia signed an agreement for trade development. There were determined how much and what products states must sell to each other.
Some Customary Law Nuance on that Hagiography: Attempt of Interpretations
Authors: Ščavinskas Marius 
Published: October 2024

Early sources about vendetta custom are some papers of the German Order provided in the XIII century. Some of these customs reflect in the Statutes of Lithuania, in some judicial cases of the XVI century, and in modified law records of other Baltic tribes, first of all in the Prussian Pamedė statute-book (XIV). But we can also find vendetta custom in hagiographical sources of late X-early XI centuries, sacred for St. Wojciech and St. Brunon of Querfurt martyrdom in Baltic lands.
The motives of murdering the missionaries let us think like that. As St. Vaitiekus came from Polish lands, he was attacked as a Polish agent or ally. Another motive—he was murdered as he was recognized as a person who was dipping people into water (baptizing) or torturing them in other ways. Here we can find elements of vendetta customs.
There is no direct data about reasons for murdering St. Brunon in the hagiographic sources provided to him. It is said that Netimer's brother Zebedene, who probably came when he found out about Netimer's baptism, told them to kill Brunon. It is worth being said that Netimer, the leader of one of the Baltic tribes, killed his anonymous brother because he didn't want to be baptized. So the anger of Zebedene was directed against Brunon as the causer of those events. Thus, there also arises a motive of vendetta.
According to E. Usačiovaitė, St. Vaitiekus was sacrificed for Baltic gods. But earlier mentioned motives for killing the missionaries don't allow giving prominence to sacral motives. If St. Vaitiekus was sacrificed to gods, how would Prussians later render his head or body as a ransom to Polish Duke Boleslaw the Brave? In the case of St. Brunon, he could incur the displeasure of pagans when he threw their idols into the fire, but it didn't happen like that. So, it doesn't allow denying the vendetta motive for disposing of the first missionaries into Baltic lands.
A szakmai és szervezeti elköteleződés szerepe a munkahelyről való kilépés szándékában tanárok körében
Authors: Koltói Lilla , Kiss Paszkál 
Published: October 2024

Háttér: A munkavállaló viszonyulása magához a munkához, valamint a szakmájához és a szervezetéhez fontos szerepet játszik abban, hogy kitart-e a munkahelye mellett vagy felmond. Aki elhivatott, vagy a jó munkahelyi kapcsolatokban találja meg a munkája értelmét, az kevésbé valószínű, hogy kilép a munkahelyéről, mint az, akinek a domináns munkaorientációja az anyagiak. Számos kutatás rámutatott, hogy a szakmai és szervezeti elkötelezettség növeli a munkával való elégedettséget, valamint csökkenti a kilépési szándék erősségét. Cél: Kutatásunkban tanárok mintáján vizsgáljuk a munkaorientáció, a szakmai elkötelezettség, valamint a szervezeti elkötelezettség és szervezetpolgári magatartás összefüggését a munkahelyről való kilépési szándékkal az öndeterminációs elmélet, azaz az alapvető pszichológiai szükségletek munkahelyi kielégülése keretében. Módszer: Az online kutatásban (N = 324) vidéki és fővárosi általános és középiskolai tanárok vettek részt. A változók közötti összefüggéseket egy útmodell segítségével, valamint szóasszociációk és szakmai remények-félelmek kvalitatív elemzésével vizsgáltuk. Eredmények: Az eredmények alapján az mondható, hogy kutatásunkban a tanárok mintáján a legfőbb munkaorientáció az elhivatottság és a társas beágyazottság, melyek az alapvető pszichológiai szükségletek kielégülése mellett hatással vannak a szakmai és szervezeti elkötelezettségre. A szakmai elkötelezettség mint legerősebb meghatározó tényező mellett a szervezeti elkötelezettség is negatív kapcsolatban áll a kilépési szándékkal. A kvalitatív adatok elemzése megerősíti és ki is bontja ezt az összefüggést: az elhivatottság, a tanítás öröme, a társas kapcsolatok munkahelyen megtartó erővel bírnak, ugyanakkor rávilágítanak a pálya rendszerszintű és egyéni nehézségeire, a tanárok anyagi helyzetüktől és pályaváltástól való félelmeire is.
Cartografía temática y recursos TIC en la enseñanza y aprendizaje de la Geografía regional de Europa
Authors: Macía Arce Xosé Carlos , Rodríguez Lestegás Francisco , Armas Quintá Francisco Xosé 
Published: October 2024

In this article, we present a classroom experience with university students in training to be secondary school geography teachers. It is based on a didactic proposal using thematic cartography (Eurostat, ESPON, ESPON-SIESTA and the Information Society Atlas in Galicia) and ICT resources (statistical sources, free picture banks, aerial photography, Google Earth and Google Maps). The proposal´s aim is to use contents from the regional geography of Europe as a base or starting point to show a series of didactic recommendations for the teaching and learning of geography and social sciences. What is more, everything is with a clear idea, from a descriptive and rote geography to an active and critical geography, in which students participate in the construction of knowledge and increase their ability to reflect on geographical issues. The results of the experience will highlight the value of these tools in secondary education. We had also previously assessed the presence of thematic cartography and ICT resources within the required official Galicia curriculum to teach geography in compulsory secondary education. The idea is to deepen the value of the curriculum in didactic code, to know what tools it offers, how it offers them and with what intentions. This solution, among other opportunities, will allow us to identify a curriculum offering a specific teaching model. On the other hand, it will also give us the opportunity to firmly rebuke all the proposals considered to be erroneous, repetitive, or of little didactic value.
Franquismo y memoria democrática: el continuo reto de la formación ciudadana en Secundaria
Authors: Andreu-Mediero Beatriz , Fernández-Fernández Alba 
Published: October 2024

Promoting political education in young people, along with instilling democratic values, is essential in our students' classroom training. However, fifteen years after the implementation of Spain's law of historical memory and amidst years of debate on the necessity of building a democratic memory around our recent history, teachers continue to face challenges when teaching recent Spanish history, encompassing the Civil War, Franco's dictatorship, and the Transition. How do students interpret present-day events in relation to the historical curricular contents they have studied during Secondary and Baccalaureate education?
This paper presents an approach to understanding the perceptions of students in the 1st and 2nd years of the Baccalaureate regarding current issues related to Francoism and democratic memory. The students had been exposed to the conceptual contents of this historical period during their 4th year of ESO and 2nd year of the Baccalaureate when the study was conducted. Our research relies on the analysis of three specific questions in a questionnaire designed to elucidate their perception of a pressing social problem, exemplified by the exhumation of Franco from The Valley of the Fallen. This approach seeks to shed light on key aspects of the teaching and learning of history, particularly in the context of secondary education.

Being a teacher today has regained new importance in the formation of citizens. On one hand, we want individuals who are critical and committed to their time, and for this, it is essential to understand the world we live in, to position ourselves within these new contexts of change and regulations. We are participants in the global and national crises, migration and its integration issues, as well as the political, economic, social, and cultural tensions of each region—factors that should enable us to provide responses in educational settings through critical reflection and participatory action. This academic work presents a qualitative and descriptive approach, arising from the analysis of documents related to the educational policy of our country: the General Education Law of Peru, the National Education Project, curricular plans, as well as the syllabus of the History and Geography degree program at a public university, with the aim of identifying, categorizing, and analyzing the subjects where citizenship-related issues are addressed, either explicitly or implicitly.
Finally, after conducting a documentary analysis of the syllabus from the History and Geography degree program at a public university in Lima, we present a discussion of the findings and the respective conclusions. It is important to mention that, regarding teacher training for citizenship, there are various Peruvian studies that provide a complementary perspective on the gaps between the teacher training intended to be provided at universities and the development of social science subjects in schools.

Abstract
Despite decades of research on yoga and depression, subjective experiences of participants in these studies have rarely been reported, and never in individuals receiving heated yoga for depression. We examined patient-reported qualitative findings from an 8-week randomized controlled trial of heated yoga for depression. Eighty medically healthy participants with moderate-to-severe depression were randomized to 8 weeks of at least twice-weekly heated yoga classes, derived from Bikram yoga, or a waitlist control. Fifty-seven participants received a clinician-administered exit interview at intervention completion/study withdrawal. The exit interview assessed: (1) how participants felt immediately following the heated yoga sessions (acute effects), (2) what they liked or found helpful about heated yoga over the 8-week intervention (positive effects), and (3) what they disliked/did not find helpful over the 8-week intervention (negative effects). Qualitative data were analyzed using thematic analysis. Acute improvements in depressive symptoms (i.e., immediately following yoga) were the most commonly reported (n = 44, 77.2%), followed by overall positive effects on depressive symptoms (i.e., over the course of the 8-week intervention; n = 33, 57.9%), including improvements in sleep (n = 10, 17.5%), energy (n = 13, 22.8%), mood (n = 18, 31.6%), motivation (n = 2, 3.5%), and concentration/decision-making (n = 5, 8.8%). Overall negative effects (i.e., over the course of the 8-week intervention) included dislike of various aspects of the intervention (n = 19, 33.3%), such as instruction (n = 7, 12.3%), difficulty (n = 7, 12.3%), repetitiveness (n = 3, 5.3%), class length (n = 2, 3.5%), and boredom (n = 7, 12.3%). Most participants reported both overall positive and negative effects (n = 37, 64.9%). Of the rest, 19 (33.3%) reported only overall positive effects, and 1 (1.8%) reported only overall negative effects. Most participant experiences were positive. Negative effects were less common and primarily involved dislike of different aspects of the heated yoga. The findings support strong acceptability and subjective improvement in depressive symptoms in depressed individuals.

Micro-implants made from metals, have been developed and modified to apply to many of the orthodontic situations one of which is absolute anchorage. The continuous use of metals in oral cavity has led to a great number of laboratory and clinical studies on the damaging effects of this products to person’s general health. Owing to this, it is must to rule out the best mini-implant with least cytotoxicity and high corrosion resistance. : The aim of this in-vitro study was to evaluate and compare the cytotoxicity and corrosion resistance of Titanium and Stainless steel Orthodontic mini-implants.The sample comprised of 20 mini-implants which were divided into 4 groups, each group consisted of 5 mini-implants.2 groups of Titanium mini-implant and 2 groups of Stainless Steel mini-implant. Subsequently, each sample was submerged in artificial saliva for 60 and 90 days, at 37°C. After this, saliva with the mini-implant corrosive product extracts were evaluated for cytotoxicity and the mini-implants were tested for corrosion resistance. In intergroup comparison for cytotoxicity, significant values seen with Orlus mini-implants and least significant values with Favanchor mini-implants. Whereas, for corrosion resistance, a highly significant difference seen for values between all the 4 mini-implants with higher values in Favanchor mini-implants. There was a highly significant difference for all the 4 mini-implants, with least cytotoxicity seen in Titanium mini-implants than Stainless Steel mini-implants. Mini-implants of all the 4 groups exhibited good corrosion resistance, with comparatively high corrosion resistance seen in Titanium mini-implants than Stainless Steel mini-implants.

Abstract
Licorice of the taxonomic genus Glycyrrhiza is a traditional Chinese medicinal plant. Its large-scale cultivation is threatened by insect pests, including the whitefly Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae). Our study (1) examined the preference of B. tabaci for G. uralensis Fischer ex de Candolle, G. glabra L., and G. inflata Batalin through caged trials; (2) identified the volatile organic compounds (VOCs) released by the three Glycyrrhiza species using headspace gas chromatography–mass spectrometry (HS-GC-MS); and (3) screened the olfactory behavior responses of B. tabaci to the key VOCs identified. The caged host preference trial showed that B. tabaci had a clear preference for G. uralensis over G. inflata and G. glabra. Through HS-GC-MS analysis, we identified 26, 33, and 31 VOCs from G. uralensis, G. glabra, and G. inflata, respectively. (3Z)-Hexen-3-ene-1-yl acetate, trans-3-hexen-1-ol, cis-3-hexen-1-ol, 3-carene, and β-pinene were selected for further olfactory response assays on the basis of variable importance projection values and quantity differences. From these, we learned that cis-3-hexene-1-ol and trans-3-hexene-1-ol, abundant in G. uralensis, attract B. tabaci, whereas 3-carene and β-pinene, abundant in G. inflata, repel B. tabaci. The different VOCs from these three species of licorice may be primary factors affecting the preference for and feeding on cultivated licorice by B. tabaci. Our results will facilitate studies on the potential of using selected VOCs for managing B. tabaci, perhaps in push–pull strategies of their use against the pest.
Risk Assessment and Remediation Options for Oil-Contaminated Soil and Groundwater: A Comparative Analysis of Chemical, Physical, And Biological Treatment Methods
Authors: Atemoagbo Oyarekhua Precious 
Published: October 2024

Oil contamination of soil and groundwater poses significant environmental and health risks, prompting this study to evaluate the effectiveness, costs, and environmental impacts of various treatment methods. A comprehensive review of 50 case studies and research papers reveals that biological treatment methods, specifically biodegradation and phytoremediation, achieve the highest contaminant removal rates (85-95%) at lower costs ($50-100/m3), outperforming chemical oxidation and solvent extraction (60-80%, $100-500/m3) and physical methods (40-70%, high energy consumption). Furthermore, risk assessment indicates biological methods pose the lowest environmental risks, while chemical methods pose the highest. Sensitivity analysis underscores the importance of site-specific conditions and contaminant levels. Overall, the results suggest biological treatment methods, particularly biodegradation, as the most effective and cost-efficient option for oil-contaminated soil and groundwater remediation.
