Tanulmányom legfőbb célja, hogy a szövegelemzés által izgalmas, kiterjedt összefüggésekre utaló motívumokat tárjak fel a címben jelölt Rakovszkyelbeszélésben, amely 2009-ben jelent meg a szöveggel azonos címet viselő, többnyire hosszabb elbeszéléseket tartalmazó, A Hold a hetedik házban című kötetben.Röviden a narrációval és az elbeszélés szerkezetével foglalkozom, hosszabban pedig az idő-és térszerkezetet, a szövegben felbukkanó szereplők lelki sajátosságait és motivációit, a mű metaforikus motívumait és azok összefüggéseit, valamint a cím jelentéslehetőségeit, illetve annak a művel való kapcsolódási pontjait vizsgálom. Végül a kötet és az eddigi Rakovszky-életmű kapcsán megjelent szakirodalom, valamint saját meglátásaim alapján megpróbálom elhelyezni a szöveget egyrészt irodalomtörténeti, másrészt pedig az írói életmű kontextusában.Egy általunk 2022-ben, középiskolai magyartanárokkal végzett pedagógusnézet-kutatás 2 -melyben fogalomtérképes, interjús és kérdőíves vizsgálat is zajlott -részben azt az eredményt mutatja az újabb, tehát 21. századi vagy kortárs irodalom kapcsán, 3 hogy a magyartanárok a végletekig feszített munkatempón, a tantervi szabályozókon és a tananyag tömörségén felül azért foglalkoznak csak csekély számú kortárs irodalommal a tanórákon, mert kevés az olyan szakirodalom, melyekben ezeknek a szövegeknek az interpretálásáról olvashatnak, ami pedig idő hiányában komoly támasza lehetne a pedagógusoknak.

“…Some studies have shown that TiO 2 could promote the formation of char layers, and both oxides of iron and SiO 2 have also been shown to promote the flame retardancy of materials. In addition, BF exhibits high strength, excellent thermal stability, and chemical stability. , Therefore, the production of inorganic paper using BFs holds a promising application in the fields of fire retardance and thermal insulation. − However, as a result of its chemical inertness, it is necessary to introduce reinforcing phases in the BF network to improve paper-forming properties and provide more possibilities for the application of BFs in the field of paper-based materials. − Aramid fiber is a high-performance organic synthetic fiber with lightweightness, good thermal stability, chemical resistance, insulation, and self-extinguishing properties. − Aramid nanofibers (ANFs) retain these excellent properties of macroscopic aramid fibers . Previous studies have shown that ANFs can be used to prepare materials with excellent thermal stability and insulation through processes such as electrospinning, vacuum-assisted pumping filtration, and freeze drying. − In addition, ANFs also own the characteristics of nanomaterials, such as high specific surface area and high aspect ratio, which help to improve the interfacial bonding with the substrate, thus enhancing the mechanical properties of the material. , ANFs can serve as reinforcing phases in composites with other matrices, such as bacterial cellulose, poly(vinyl alcohol), hydroxyethyl cellulose, and carbon nanotubes, improving interface bonding and resulting in a significant enhancement of mechanical strength. − Therefore, ANFs show great applications in various high-performance and multifunctional materials.…”

The flame-retardant paper has gradually evolved into a necessary material in various industries as a result of the rising importance of fire safety, energy efficiency, and environmental preservation. Traditional cellulose paper requires the addition of a large amount of flame retardants to achieve flame retardancy, which poses a serious threat to mechanical quality and the environment. Therefore, there is an urgent need to develop inorganic fiber flame-retardant paper with good flexibility, high thermal stability, and inherent flame retardancy. Herein, inspired by the "brick-and-mortar" layered structure of nature nacre, we developed a layered composite paper with a unique alternating arrangement of organic−inorganic fibers by synergistically integrating environmentally sustainable basalt fiber (BF) and high-performance aramid nanofibers (ANFs) through a vacuum-assisted filtration process. The as-prepared ANFs/BF composite paper exhibited low thermal conductivity (0.024 W m −1 K −1 ), high tensile strength (54.22 MPa), and excellent flexibility. Thanks to its excellent thermal stability, the mechanical strength remains at a high level (92%) after heat treatment at 300 °C for 60 min. Furthermore, the peak heat release rate and smoke generation of ANFs/BF composite paper decreased by 44.6 and 95.3%, respectively. Therefore, the composite paper is promising for applications as a protective layer in flexible electronic devices, cables, and fire-retardant and high-temperature fields.

“…Notably, basalt fiber is an environmentally friendly option with a cost comparable to other fiber types. Moreover, it enhances temperature resistance, corrosion resistance, chemical properties, and mechanical properties (Karacor and Ozcanli, 2022;Shoaib et al, 2022;Tamás-Bényei and Sántha, 2023).…”

This study investigates on the impact of basalt fiber reinforcement concrete in protected building and structures. Basalt fibers, derived from the melting of basalt rock at temperatures ranging from 1,500 to 1700°C, are recognized as sustainable and environmentally friendly fiber materials. Various studies have revealed differing optimal percentages of basalt fibers for enhancing the mechanical and chemical properties of concrete. The objectives of this paper are to investigate the effects of basalt fibre reinforcement on mechanical properties like tensile, compressive, and bending strengths. Additionally, performance indicators like void content, water absorption, chloride ion permeability, alkali and slag resistance, temperature stability, shrinkage characteristics, and abrasion resistance will be evaluated. Basalt fibre is typically utilised to increase the mechanical properties and durability of concrete, which has an impact in the effect on protected buildings and structures. The findings indicate that the most effective percentage range for improving mechanical properties lies between 0.1% and 0.3% of basalt fibers. Notably, concrete reinforced with basalt fibers demonstrates superior mechanical and chemical performance in alkaline environments compared to other fiber types. Moreover, the addition of 0.5% basalt fibers to concrete has been shown to significantly reduce chloride ion penetration, as evidenced by a decrease in RCPT load from 2,500 (C) to 1900 (C), indicative of enhanced chloride resistance. Reinforced concrete containing basalt fibers exhibits remarkable temperature resistance, withstanding temperatures exceeding 800°C due to its high-water absorption capacity. Additionally, basalt fibers exhibit resilience at temperatures up to 200°C. However, it is noted that the introduction of 0.14% basalt fibers leads to a slight increase in water absorption from 4.08 to 4.28. In general, basalt fibres are beneficial to many aspects of concrete; they strengthen resistance to temperature, alkali, acid exposure, and chloride while also improving mechanical qualities such as bending and tensile strength. The development of basalt fibres that extend building lifespans and improve concrete quality for structural engineering applications is making encouraging strides, according to all the results.
