René d’Anjou in the Twilight of an Era: Last Prince or a “Roi Imaginé”
No full textThe launch of the Italian campaigns and the entry of Charles VIII into Naples in 1494 is a traditional political turning point in French history, on the border between the Middle Ages and the Early Modern period. This foreign political expansion was, of course, due to a number of things, one of which was the takeover of the Angevin inheritance, paved by the death of René of Anjou in 1480. However, the lord of Anjou and Provence was not only a great prince of this period, but his life’s work often crossed the sometimes blurred line between reality and imagination. The kingdoms of the dynastic legacy of the past, never possessed or long lost by the end of the fifteenth century, were revived again in his hands but in many ways for the last time. The presentation will seek to explore the imaginative elements of René’s figure and the extent to which these were perpetuated for a new, “unified” kingdom of France. As he proudly stated in his title: was the King of Jerusalem, Sicily and Hungary really one of the last counts of medieval France or was he already the prince of a new world
Trend analysis of temperature over the Meghalaya Plateau: A case study of Ri Bhoi District
No full textClimate change is a reality in the present world, and most nations are fighting this menace by bringing in mitigation measures to check our carbon footprint and developing measures to make ourselves more resilient to hazards associated with climate change and global warming. These necessities measure the nature and degree of change in the climatic elements, viz., temperature, rainfall, etc. Located on the northern slopes of the Meghalaya plateau, the Ri Bhoi district is characterized by a complex climatic condition owing to its altitudinal differences. The district is divided into two distinct zones: the Highland zone, located closer to Shillong, and the Lowland zone, lying closer to the Brahmaputra plains. The economy of Ri Bhoi district is agrarian in nature, where most of the rural populations live close to nature, following subsistence agriculture with fewer technological innovations; hence, awareness of temperature changes becomes essential for carrying out their livelihoods. In this context, the present paper attempts to analyze both the minimum and maximum average monthly, seasonal, and annual temperatures over two decades (1999–2019) in both zones. The Mann-Kendall (MK) trend test and Sen’s slope estimate were employed to find the nature of the temperature trend and its magnitude in the two zones of Ri Bhoi District. The findings suggest an erratic behavior of both the maximum and minimum temperature has been observed in the Highland and Lowland zones of Ri Bhoi district over the past two decades, impacting agriculture and agro-based livelihoods
Assessing animal species at risk for SARS-CoV-2 transmission: Bioinformatic analysis based on Angiotensin-Converting-Enzyme (ACE2) homology in edible and other animals
No full textA novel coronavirus called SARS-CoV-2 was detected in December 2019, leading to the COVID-19 pandemic that began in Wuhan, China. This virus is classified as severe acute respiratory syndrome SARS-CoV-2 due to its significant similarities with the SARS-CoV virus. Initially, bats were recognized as the primary animal hosts, but later research indicated that other animals could also serve as reservoirs, posing health risks, particularly for those species consumed by humans. SARS-CoV-2 binds to the angiotensin-converting enzyme 2 (ACE2) as its cellular receptor, utilizing the receptor-binding domain (RBD) of its spike protein, much like SARS-CoV does.
The study aimed to identify animals, particularly edible animals, that may be susceptible to infection by SARS-CoV-2. This was achieved through bioinformatics techniques, including alignment analysis of genomic sequences from selected animals, identity percentages comparison, and phylogenetic analysis based on the interaction between ACE2 and the receptor-binding domain (RBD) of SARS-CoV-2. This analysis identified rabbits, donkeys, alpacas, horses, wild boars, field rats, and monkeys as potentially susceptible edible animals. Additionally, primates were highlighted due to their close genetic resemblance to humans. Overall, 22 animals worldwide were identified as susceptible, marking them as possible reservoirs and hosts for the virus, emphasizing the need for vigilance around animals that humans may contact or consume
The current status, challenges and prospects of native pig production and large-scale farming in Laos
No full textThis review aimed to investigate the potential native pig development and the trend that large-scale farming may influence native pig production in Laos. The review found that native pigs were estimated to be around 88% of the total pig population in Laos in 2023. Commercial pig farming was found only in the main cities, particularly the central and southern provinces, which increased from 578 in 2019 to 703 farms in 2022 and 737 farms in 2023. Due to the serious economic crisis starting in 2021, many Lao pig producers stopped their businesses, leading to the decline of the commercial pig population by almost 30% in 2023 compared to 2022. The average pork per capita consumption in Laos in 2021 was estimated at about 14.2 kg. Though not as high as the backyard, commercial farms still contribute essentially to the pork supply in Laos (12%), increasing the volume from 87,628 tonnes in 2015 to 137,775 tonnes in 2024. The main native pig producers are small-scale rural farmers who have not yet improved productivity or reproductive performance, and the main purpose of their production is household consumption rather than market orientation. However, farmers, mainly in the main cities, improved them by cross-breeding native pig sows with Duroc boar for better lean meat. The main challenges for native production in Laos include poor farm setup and management, high cost of commercial feed, and poor breeding and genetic management. Therefore, creating awareness of the benefits of setting up a pig farm and management, providing better option strategies for utilising locally available feeds, and providing better strategies on pig breeding could improve native pig production in Laos.
Investigating the potential for dual-purpose use in winter oats
No full textDual-purpose usage is not a common technology for oats in Hungary, which is not surprising, as the area sown to our main crop is also very low. Yet the crop has a lot of untapped potential, not to mention its excellent nutritional parameters. In our experiment we investigated how much biomass can be expected after mowing winter oats at different phenological stages and whether we can expect a valuable grain yield after this process. Mowing was carried out at one-week intervals on a total of 4 occasions with 2 cutting heights. Plant height and NDVI values of the vegetation in the plots were measured during the experiment. After the harvest of the fully ripened grains, the yield and the thousand kernel weight (TKW) were determined. Our results show that with a lower cutting height (6 cm), a higher biomass yield can be achieved. The cutting height had no statistically verifiable effect on either NDVI or plant height. Droughty weather conditions during subsequent mowing significantly reduced the regeneration capacity of the plants, which was strongly reflected in the measured parameters. Furthermore, a higher grain yield was measured at a cutting height of 9 cm, which decreased gradually with the mowing time. Neither the cutting height nor the mowing time had any effect on the TKW
Két oktatási (a projektalapú és a kutatásalapú) stratégia hatása a diákok teljesítményére a kiválasztott biológiai absztrakt fogalmak esetében
Full text linkThe purpose of this study was to ascertain how two instructional strategies—project and inquiry—affect students' mastery of particular abstract biological concepts. The study used a quasi-experimental pretest-posttest control group design. 120 SS II Biology students were chosen at random from six coeducational schools located in two Local Government Areas (LGAs) in the state of Kwara. Treatment groups were assigned to participants at random. The Biology Student Achievement Test (r=0.88) and the Teachers' Instructional Guide on Project and Inquiry Strategies were the instruments utilised. Two theories were developed and put to the test at the significance level of 0.05. The intervention had a significant main effect on students' achievement on a subset of selected biological abstract concepts (F(2, 107) =12.061; p<0.05, partial η2 = 0.184), according to an analysis of covariance conducted on the gathered data. The students in the Conventional Strategy (CS) control group have the lowest adjusted mean achievement values (x ̅ = 17.20), whereas the students in the Project Strategy (PS) treatment group 1 have the highest adjusted mean achievement values (x ̅ = 23.21). It is indicated that PS > IS > CS is the order. The mean growth in accomplishment values for male students was higher at 21.94, compared to 17.13 for female students. Project and inquiry methodologies should be implemented in order to raise students' accomplishment in biology's abstract concepts, according to the findings.A tanulmány célja annak feltárása, hogy két oktatási stratégia – a projektalapú és a kutatásalapú tanítás – miként befolyásolja a diákok teljesítményét bizonyos absztrakt biológiai fogalmak elsajátításában. A kutatás kvázi-kísérleti, előteszt–utóteszt kontrollcsoportos elrendezést alkalmazott. A vizsgálat során 120 középiskolás (SS II) biológia szakos diákot választottak ki véletlenszerűen hat, két helyi önkormányzati területen (LGA) található koedukált iskolából Kwara államban. A résztvevőket véletlenszerűen osztották be a csoportokba. Az alkalmazott eszközök közé tartozott a Biológiai Diák Teljesítményteszt (r=0,88) és a Tanári Útmutató a Projekt és Kutatásalapú Stratégiákhoz. Két kutatási hipotézist állítottak fel, amelyeket 0,05-ös szignifikanciaszinten teszteltek. Az összegyűjtött adatokon elvégzett kovarianciaelemzés (ANCOVA) eredményei szerint az oktatási beavatkozás szignifikáns főhatást gyakorolt a diákok teljesítményére az adott absztrakt biológiai fogalmak körében (F(2, 107) =12,061; p<0,05, parciális η² = 0,184). Az átlagosan legmagasabb teljesítményértékeket a projektalapú stratégia (PS) szerinti oktatásban részt vevő diákok érték el (x̅ = 23,21), míg a hagyományos oktatási módszert (CS) alkalmazó kontrollcsoport diákjai mutatták a legalacsonyabb teljesítményt (x̅ = 17,20). Az eredmények szerint a stratégiák hatékonysága a következő sorrendet mutatta: PS > IS > CS.A nemek közötti különbségeket tekintve a fiúk átlagos teljesítménynövekedése (x̅ = 21,94) magasabb volt, mint a lányoké (x̅ = 17,13). A kutatás eredményei alapján javasolt a projektalapú és a kutatásalapú tanítási módszerek szélesebb körű alkalmazása a biológia absztrakt fogalmainak hatékonyabb elsajátítása érdekében
Az agilitás fejleszthetőségének vizsgálata a tanórán kívüli tevékenységek során
Full text linkIn contemporary sports, achieving higher levels of performance has become almost unimaginable without scientific support. This is equally true for modern football, where agility stands out as one of the most critical abilities. Agility is a multifaceted skill that encompasses components such as change-of-direction running, recognizing game situations, decision-making, and response time. While physical abilities contribute significantly to performance enhancement, the distinguishing factor in agility often lies in the speed of decision-making. The objective of our research was to investigate the trainability of agility. Specifically, we aimed to design an agility test that evaluates not only physical abilities related to direction changes – such as dynamic leg strength and running technique – but also agility in its full complexity, incorporating all related decision-making mechanisms. Our study sought to determine the extent to which agility could be developed in the examined age group through an 8-week training program consisting exclusively of agility tests. School sports clubs provided an appropriate foundation for the research, as participants were non-elite athletes, making short-term progress more likely. The study was conducted in 2023 at the gymnasium of Huszár Gál High School, Elementary School, Basic Art Education Institution, and Kindergarten. The participants were first- and second-grade boys, with an average age of 7.4 years. A total of 16 students took part in the research. At the start of the study, during the initial assessment, students performed several tests: a 20-meter straight-line sprint, a shadowing agility test, an auditory signal agility test, and a predetermined course agility test with a known route. Following this baseline measurement, an 8-week period commenced, during which students participated in sports club sessions twice a week. These sessions incorporated agility tests as training elements. Specifically, students performed three Agility T-tests and three Illinois agility tests during each session. After eight weeks, post-training assessments were conducted under identical conditions. The results indicated that incorporating agility tests as training elements led to significant improvements in time-based performance metrics. It was also evident that tasks requiring decision-making took longer to execute compared to those following predetermined routes. Our findings confirmed the hypotheses set before the research and provided answers to the research questions posed.Napjainkban az egyre magasabb szintű sportteljesítmény elérése tudományos háttér nélkül már szinte elképzelhetetlen. Így van ez a mai modern labdarúgásban is, ahol az egyik legfontosabb képesség az agilitás képessége, mely összetett, több részképességet foglal magába, úgy, mint az irányváltoztatásos futás, a játékszituációk felismerése, a döntéshozatal és a reagálás. A fizikai képességek fejlesztésével a sportolók teljesítőképessége nő az agilitás tekintetében, ami különbségként jelentkezhet, az a döntéshozatal gyorsasága. Jelen kutatásunk célja az agilitás fejleszthetőségének vizsgálata volt. Célkitűzéseink között szerepelt egy olyan agilitásteszt összeállítása, amelyben nem csupán az irányváltoztatással kapcsolatos képességeket – mint a dinamikus láberő, futótechnika – lehet vizsgálni, hanem az agilitást a maga komplexitásában minden hozzátartozó döntéshozatali mechanizmussal együtt. Kutatásunk során arra kerestük a választ, hogy az általunk vizsgált korosztályban milyen mértékben fejleszthető az agilitás egy olyan 8 hetes edzésprogrammal, amelyben kizárólag agilitástesztek szerepeltek. Az iskolai sportkörök megfelelő alapot nyújtottak a vizsgálatokhoz, hiszen a foglalkozáson résztvevők nem élsportolók, így egy rövidtávú vizsgálaton hamarabb várható fejlődés. A vizsgálatokat 2023-ban a Huszár Gál Gimnázium, Általános Iskola Alapfokú Művészet Oktatási Iskola és Óvoda tornatermében végeztük el. A vizsgált személyek valamennyien az iskola első és második osztályos fiú tanulói voltak. Életkorukat tekintve az átlagéletkor 7,4 év volt. Összesen 16 fő vett részt a kutatásban. A kutatás kezdetén a bemeneti mérés során a tanulók végrehajtottak egy 20 méteres egyenes vonalú futástesztet, egy követéssel történő agilitástesztet, egy hangjelzésre történő agilitástesztet, végül pedig egy irányváltoztatással történő agilitástesztet, ahol már ismert volt az útvonal. A mérést követően kezdetét vette egy 8 hetes időszak, melyben heti két alkalommal a sportköri foglalkozásokon belül végezték a gyerekek az agilitásteszteket, mint edzéselem. A foglalkozások alkalmával 3 darab Agility T tesztet és 3 db Illinois agilitástesztet hajtottak végre a tanulók. A 8 hetet követően ugyanolyan körülmények között került sor a kimeneti mérésre. A vizsgált eredmények arra mutattak rá, hogy az agilitástesztek edzéselemként történő alkalmazása jelentős fejlődést eredményezett az időeredményekben. Az is igazolódott, hogy az olyan feladatokban, ahol a döntéshozatal is szerepet játszik több időt vesz igénybe a végrehajtás, mint amikor egy előre ismert útvonalon haladnak végig a tanulók. A vizsgálatok során feltett kérdéseinkre választ kaptunk, a kutatás előtt megfogalmazott feltételezéseink beigazolódtak
A nők szerepe a marokkói Gnawa közösségben: pszichoterápia, szellemidézés és gyógyítás
Full text linkDescendants of slaves from the Sub-Saharan countries brought to Morocco, characterized by their special music with unique rhythms accompanied with spiritual traditions and practices for healing purposes. The Gnawa community represents an intangible cultural heritage in Morocco due to its special rituals and traditions in healing the sick from various diseases by practicing syncretic rituals, trance dances and spiritual music that makes the participant left up with ecstasy. These practices are centred in a ceremony called ‘lila’ in which women play a significant role by leading the healing rituals and communicating with the spirits that possess the participant in order to reach God.A Gnawa közösség tagjai a Szubszaharai Afrikából Marokkóba hurcolt rabszolgák leszármazottai, akik különleges ritmusokkal kísért zenéjükről, valamint spirituális hagyományaikról és gyógyító gyakorlataikról ismertek. A Gnawa kultúra Marokkó szellemi kulturális örökségének része, amely egyedülálló rituálékkal és hagyományokkal járul hozzá a betegek gyógyításához. A gyógyító szertartások szinkretikus rítusokat, transztáncokat és spirituális zenét foglalnak magukban, amelyek révén a résztvevők eksztatikus állapotba kerülnek. Ezek a gyakorlatok egy „lila” nevű ceremóniában összpontosulnak, amelyben a nők kiemelkedő szerepet játszanak: ők vezetik a gyógyító rítusokat, valamint kapcsolatot teremtenek a megszálló szellemekkel, hogy a résztvevők elérhessék Istent
