Published: March 2024

Németország vállalatai, (melyek között megtalálhatóak kicsik, közepesek és nagyvállalatok egyaránt) a legnagyobb tőkebefektetőnek számítanak Magyarországon. Ezen írás szerzői indokoltnak tartják, hogy a Németországhoz fűződő kereskedelmi és együttműködési kapcsolatok elemzésén túlmenően megfelelő figyelem fordítódjon az egyes tartományokhoz fűződő kapcsolatok differenciált megközelítésére, különös tekintettel az egyes tartományok fejlettségi adottságaira és esélyeire, valamint a Magyarországhoz fűződő kapcsolatok tradícióira és az e kapcsolatokban rejlő lehetőségeire. Több, a magyar kapcsolatok szempontjából kiemelt jelentőségű tartománnyal vegyes bizottság működött és működik ma is, melyek tevékenységükkel hozzájárulnak a gazdasági társadalmi lehetőségek kiaknázásához, a befektetési lehetőségek felméréséhez, a két ország közötti párbeszéd és együttműködés erősítéséhez. A vegyes bizottságok és más keretek között tett közös kezdeményezések jelentősen hozzájárultak és hozzájárulhatnak a jövőben is az európai fejlődéshez.

Published: March 2024

A Z generáció munkahelyválasztásának szempontrendszerét számos tényező befolyásolja. Egyéni preferenciák mellett a generáció-specifikus jellemzők, makrohatások és aktuális fogyasztói, HR trendek. Meglátásunk szerint a mai munkaerőpiaci körülmények között különösen fontos, hogy egy munkáltató képes legyen a potenciális munkavállalókat érdemben megszólítani, elérni és megtartani. Ehhez komplex munkáltatói márkaépítési stratégiára van szükség, amely a szervezetfejlesztési szempontok mellett, a generációs sajátosságokat épp úgy figyelemeb veszi, mint az egyéni szinten realizálódó munkahelyválasztás preferenciarendszert és a nagyobb teljesítményre ösztönző motivációs eszközöket. Ebben a tanulmányban a Z generációra, és különösen a kínai fiatalokra összpontosítunk, abból a szempontból, hogy hogyan választanak munkahelyet, és hogyan motiválják őket a jobb teljesítményre.

Background: Synchronous colorectal cancers are defined by the presence of at least two cancers (primary self-standing tumors) in the same time, in the same patient. In these conditions, the tumor with the maximum diameter has nomenclatures such as “primitive”, or “index”. The preoperative diagnosis of synchronous tumors is very important, as it can turn into metachronous tumors, which require a new surgical intervention.

Case report: In the following, we report a case of a 54 year-old patient without any related oncological family history but with important cardiovascular comorbidities, who has been operated for stenotic synchronous cancer of the recto-sigmoid junction and middle rectum. During the initial work-up, no liver or peritoneal metastases were noted on the CT scan. The surgical intervention opted for was a recto-sigmoid laparoscopic with subtotal mesorectal excision followed by a termino-terminal mechanical stapled colorectal anastomosis. The histopathological examination showed both lesions to be moderately differentiated (G2) adenocarcinomas, with subserosal invasion in 2 of the 12 detected lymph nodes. Immunohistochemistry further revealed microsatellite instability, with MLH1 and PMS2 mutation.

Conclusion: The literature review highlights certain particular aspects regarding the clinical, surgical and morphological management of such cases compared to cases with single tumor. The peculiarity of this case was laposcopic resection of the colon segment, and the microsatellite instability of the specimen, assessed by ancillary studies. Early preoperative diagnosis of synchronous tumors allows the selection of appropriate therapeutic management, depending on their location at the level of the affected colonic segments.

A teacher is a person who has academic competence and qualifications as a learning agent, provides knowledge, provides guidance and direction to students according to their scientific field, and will make students intelligent, smart, able to understand the knowledge that has been taught and has broad and critical thinking insights. Shadow teachers are teachers who work directly and face to face with children and assist the class teacher. The presence of a shadow teacher is very helpful in conditioning the class when the class teacher is providing lessons and explanations to students. Shadow teacher will deal with one student with special needs. Competency standards for shadow teachers meet three criteria, pedagogical standards, personality standards and professional standards. To become an shadow teacher, you need a supportive academic education, having an educational certificate at the level of D-IV/S1 PGTK or psychology or other relevant education. Or a diploma D-II PGTK from an accredited study program. The need for shadow teachers who are really needed by inclusive schools is not yet balanced with the number of students with special needs in schools. Apart from that, shadow teachers have not been provided with adequate training. This research was carried out through a literature review with a qualitative approach. The systematic review process uses various literature reviews and articles from national scale scientific journals. The analysis obtained from the study is that training is needed to support the competence of accompanying teachers in the process of teaching students with special needs. The training required is 1) explanation of inclusive education, 2) children with special needs and their characteristics and diversity, 3) growth and development of children with special needs, 4) how to provide stimulation to children with special needs, 5) how to care for and protect children with special needs, 6 ) create an individual learning program. The number of shadow teachers currently in Samarinda city inclusive schools is not yet comparable to the inclusion schools that have been decreed by the Mayor.

Published: March 2024

Before new trends emerge after the COVID pandemic is over, this paper aims to examine the development of recent research trends in the theories and methods applied to studies of local communities' behaviours towards environmental protection in the years 2018–2021. This paper presents a review of more than one thousand local communities' environmental conservation behaviours that was published between 2018 and 2021. The purpose of this research is to achieve its objective. Following that, content analysis was performed on the articles that were pertinent. In order to clarify, categorise, and interpret the current research on rural tourism definitions and applications, a classification scheme and an extensive literature review have been presented in this article. Both of these elements are presented in this paper. A total of 38 academic papers from 25 different journals published between the years 2018 and 2021 are included in this review's classification scheme. These papers are organised according to their use of one of five primary keywords: local, community, environmental, conservation, or behaviour. The fact that the articles under consideration in this research were only found in the Scopus database represents a potential limitation of the bibliometric mapping. This research contributes to the existing body of knowledge by conducting a bibliometric review of studies that have already investigated locals' perspectives on tourism, and this review adds to the tourism literature by analysing the growing trend of looking at how different communities' actions affect environmental protection. Future research on these trends can be guided by identifying where the gaps in knowledge currently exist.

This article aims to analyze the waste problem at the new Mayangsari River tubing tourist attraction, Semarang City, and find out the forms of waste management at the Mayangsari River tubing tourist attraction, Semarang City. This study uses a descriptive qualitative research method. This research is located in Kalipancur Village, Ngaliyan District, Semarang City. The data in this study were collected through data collection techniques in the form of interviews, observation, and documentation. The informants in this study were taken from the management of the Tourism Awareness Group (Pokdarwis), the management of the Family Disaster Preparedness (KSB), the management of the River Care Community (KSP), the Rukun Warga and Rukun Tetangga groups, as well as the community, especially those who open businesses in these tourist areas. Data were analyzed using Miles and Huberman's interactive analysis model. The opening of the Mayangsari river tubing tour has resulted in an increase in the amount of waste generation. The increase in the amount of waste occurs on holidays in line with the high number of visitors. Every week about half of the contents of the garbage pickup is waste generated from tourist sites. The most common type of waste is plastic from food scraps. Trash is still found dumped around the river. Garbage is mixed even though organic and non-organic trash bins have been provided by the manager. Waste management through the application of 3 R (reduce, reuse, and recycle) has not been carried out by the management of this tourist spot. The waste generated from this tourist location is only limited to being collected then transported and then disposed of.

Metodología: se ha empleado la metodología usual en las ciencias jurídicas para un estudio jurisprudencial; esto es, estudio de la resolución, de la normativa y de los estudios doctrinales relevantes sobre el tema en cuestión. Resultados: el Tribunal Constitucional ha validado la constitucionalidad de la declaración de interés general de la función de asistencia y cooperación de las diputaciones provinciales por parte de la Generalitat Valenciana, con el propósito de facilitar su participación económica obligatoria en la dotación del fondo de cooperación municipal. Se muestra la discrepancia de criterio de los magistrados del Tribunal, haciendo especial mención a los votos particulares emitidos. Conclusiones: la STC 124/2023 revela cómo la coordinación ha posibilitado un medio de interferencia sobre las diputaciones provinciales, planteándose ciertas dudas desde la perspectiva del respeto a la autonomía provincial. No se descarta la posibilidad de que en el futuro otras comunidades autónomas consideren oportuno realizar detracciones forzosas de fondos provinciales para destinarlos a los municipios situados en su ámbito territorial, limitando de esta manera la plena disponibilidad de sus ingresos.

Published: March 2024

Herbal medications have high demand in both advanced and budding nations because of their increased bioavailability and minimal side effects. In the present study, the ethanolic and acetone extracts from Bauhinia tomentosa leaf were investigated for their antibacterial potential against Gram-positive (Staphylococcus aureus), Gram-negative bacteria (Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa) and yeast (Candida albicans). Phytochemical examination revealed the presence of diverse secondary metabolites, such as flavonoids, alkaloids, phenolic compounds, tannins, and saponins in leaf extracts. GC-MS analysis detected 15 chemical constituents in the extracts, with the major compounds such as 2-Phenyl-1-3- Oxazol, Caryophyllne, dodecanoic acid, d-glycero-d-galacto-haptose, Phytol, Tetradecanoic acid, 1-Hexacosanol, Isophytol, Oleic acid, 7H-Purine-2-amine,7-methyl, and eicosane. Antibiotics study have been used to explore drug resistance in pathogens. These extracts exhibited concentration-dependent antibacterial activity against the tested bacterial strains. The acetone displayed higher antibacterial activity than the ethanol extract, which could be attributed to the efficiency of the solvent extract in extracting the bioactive compounds. The findings of this study offer valuable information regarding the phytochemical composition and antibacterial potential of B. tomentosa leaf extract. The bioactive compounds identified through GC-MS analysis may be responsible for the observed antibacterial activity. Furthermore, the leaf extracts were non-toxic, and their potent antibacterial effects may be attributed to the presence of bioactive phytoconstituents. Future studies may contribute to the development of B. tomentosa based antimicrobial agents with potential therapeutic applications.

Published: March 2024

As fraturas/luxações da vértebra L7 são frequentes na coluna vertebral de cães e os sinais clínicos neurológicos decorrem do comprometimento das raízes nervosas da cauda equina, e perda de relação de sustentação da pelve e sacro com o restante da coluna lombar, o que pode ser suficiente para impedir a deambulação do animal. O tratamento conservativo pode ser realizado em cães com sinais neurológicos leves e com pouco deslocamento dos corpos vertebrais, no entanto, o tratamento cirúrgico pode prevenir lesões adicionais à cauda equina, aliviar a compressão medular e promover estabilidade. Existem várias técnicas cirúrgicas para estabilização das fraturas lombossacras, mas foram descritas há muitos anos, as ilustrações estão disponíveis apenas em imagens em preto e branco ou de baixa qualidade, dificultando o entendimento dos procedimentos. Dessa maneira, o objetivo deste trabalho é apresentar uma breve revisão sobre as técnicas, adicionando imagens autorais que permitam melhor entendimento da mesma, além de material ilustrativo para referências em trabalhos futuros. As imagens foram confeccionadas por meio de instrumentação em cadáveres e modelamento computacional 3D.

Geological structure and metallogeny of Precambrian sedimentary structures of western Aldan-Stanovy Shield
Authors: Puliaev N. A.
Published: March 2024

The article presents the results of the study by various geologists of the geological structure and prospects of ore-bearing trog complexes performing structures such as throgs, which were identified at different stages of geological research in the western part of the Aldan-Stanovy shield. The main types of traction complexes and their sections were determined. The nature of the occurrence of sedimentary (terrigenous), volcanogenicsedimentary and metavolcanic rocks performing throgs and forming throg complexes was established. The nature of the ratio of these rocks in the context of the trog complex in the studied trogs was described. The results of the study of trog complexes showed that they are generally characterized by facies variability, heterogeneity of metamorphism and dynamothermal processing of rocks (especially in the sides of trogs) with the formation of mylonites and cataclasites. It was established that the throgs are confined to three regional systems of discontinuous disturbances. Both consonantal and secant discontinuities were marked inside the throgs, defining their block tectonics. The results of determining the geological age of the rocks of the trogovoi complex were presented. The trog structures are characterized by ore mineralization associated with the processes of sedimentation (ferruginous quartzites, copper sandstones) and volcanogenic ore formation (copper-crusted and polymetallic mineralization), as well as with the processes of metamorphogenic-hydrothermal redistribution of ore matter (stratiform scheelite mineralization, ore-bearing quartz veins). It was also found that the metallogeny of the trog structures has not been studied sufficiently. Nevertheless, the majority of geologists who studied the trogovye complexes noted in their reports that Precambrian trogovye complexes can be considered as important and metallogenically promising geological objects in the western part of the Aldan-Stanovy Shield and deserve more in-depth study.

Oxidovanadium β-nitro 5,10,15,20-tetraphenylporphyrinato, VOTPPNO2 (1a) and oxidovanadium β-nitro 12,13- dibromo 5,10,15,20-tetraphenylporphyrinato, VOTPPBr2NO2 (2a) were designed and synthesized in good yield. All of the synthesized oxidovanadium porphyrins were characterized by various spectroscopic techniques viz. UV-visible, FT-IR, EPR spectroscopy and MALDI-TOF mass spectrometry, cyclic voltammetry and computational studies. In TGA study, both oxidovanadium porphyrins 1a and 2a show good thermal stability up to 277 ºC and 303 ºC respectively. The paramagnetic nature of vanadium of 1a and 2a were confirmed by electron paramagnetic resonance spectroscopy. The HOMO-LUMO gaps of 1a and 2a show less than VOTPP confirmed by cyclic voltammetry studies. In DFT studies, vanadyl porphyrin 2a slightly exhibited nonlinearity as compared to 1a due to presence of bromo groups on the porphyrin core. Oxidovanadium porphyrin catalysts, 1a and 2a were investigated for selective epoxidation of various alkenes using H2O2 as an oxidant and NaHCO3 as promotor in CH3CN at 60 ℃ with good TOF values (6159-8746 h-1). Both the catalysts mimic vanadium bromoperoxidase activity for oxidative bromination of thymol and some other phenols using HClO4-KBr-H2O2 system in water at room temperature with good TOF values (22899-35357 h-1). 1a and 2a were recovered at the end of the various catalytic cycle indicating their reusable and sustainability.

We present the gas-phase synthesis of 2-methyl-prop-1-ene-1,1-diol, an unreported higher energy tautomer of isobutyric acid. The enol was captured in an argon matrix at 3.5 K and characterized using IR and UV/Vis spectroscopy, combined with density functional theory computations. Upon irradiation the enol rearranges to form isobutyric acid and dimethylketene. Moreover, we also identified propene, photochemically formed from dimethylketene.
Development of a portable SERS tool to evaluate the effectiveness of washing methods to remove pesticide residue from fruit surface

Pesticides are commonly used to control pests and improve crop productivity in agriculture. Upon post-harvest, concerns have emerged regarding the potential harmful health effects resulting from the presence of pesticide residues. Analyzing these residues on crop surfaces is challenging due to their typically low concentration and potential interference from the complex matrix of the produce’s surface. To address this challenge, we developed a portable surface-enhanced Raman spectrometer (SERS)-based approach that offers a fast turnover rate, simplified protocol, on-site capability, and high sensitivity. Further, this new approach was used to investigate the efficacy of various washing methods to remove a fungicide (ferbam) from peach surfaces. Household washing methods were compared with the chlorine wash used in the food processing industry (25 mg/L, sodium hypochlorite). The 1- and 5-minute chlorine wash (25 mg/L) proved most effective in removing pesticide residues, compared to tap water, sodium bicarbonate, and vinegar-soaking methods. Among household washing agents, sodium bicarbonate and vinegar provided superior removal effectiveness compared to tap water. In addition, SERS analysis on the flesh and backside of the skin revealed negligible penetration of ferbam into peaches. This study not only introduces an innovative method for measuring pesticide residues but also contributes to our understanding of pesticide removal and penetration. This knowledge is crucial for the effective use of pesticides and mitigation of their exposure through food sources.

We studied the adsorption of CO on PdPt nanoparticles with different metal ratio using theoretical calculations (DFT) and experimental investigations. A model catalyst was employed, where platinum (Pt) and palladium (Pd) were co-deposited via physical vapor deposition on the surface of α-Al2O3(0001). CO was used as a probe molecule for the particles’ surface composition. Polarized infrared reflection absorption spectroscopy (FT-IRRAS) enabled the observation of CO adsorption on top and side facets. The role of the Pd/Pt alloy ratio on the adsorption was investigated by comparing the FT-IRRAS data for different alloy arrangements and pure Pd and Pt nanoparticles. The dependence of the IR bands on the local atomic pattern was investigated via DFT calculations, revealing that both bulk alloy composition, as well as nearby atoms, influence the wavenumber of the bands.

Photoelectrochemical (PEC) water splitting is attracting significant research interest in addressing sustainable development goals in renewable energy for the future. Current state-of-the-art, however, cannot provide photoanodes with simultaneously high efficiency and long-lasting device lifetime. Here, we report a large-scale NiFe oxyhydroxides-alloy hybridized cocatalyst layer on photoanodes that exhibit a record value of applied bias photon-to-current efficiency (ABPE) of 4.24% in buried homojunction-free photoanodes and stability over 250 hours with above 88% retention of the initial current density. These performances represent an increase over the present highest-performing technology by 408% in stability and the most stable competitor by over 330% in efficiency in alkaline media. These results originate from a previously unexplored mechanism of light-induced atomic reconfiguration and surface amorphization in NiFe-based materials. This process self-generates at low biases and, in short times, a catalytic-protective amorphous/crystalline heterostructure that provides abundant highly catalytic active sites for reaction and insulates the photoanode from performance degradation. NiFe oxyhydroxides generated by photons are more than 200% higher than the quantity that pure electrocatalysis would otherwise induce, overcoming the threshold for an efficient oxygen reduction reaction in the device. While of immediate interest in the industry of water splitting, the light-induced NiFe oxyhydroxides-alloy co-catalyst developed in this work provides a general strategy to enhance further the performances and stability of PEC devices for a vast panorama of chemical reactions, ranging from biomass valorization to organic waste degradation, and CO2-to-fuel conversion.

Published: March 2024

The packing and geometry of compressed small molecule precursors largely dictate the kinetically controlled formation processes of carbon nanothread materials. Structural ordering and chemical homogeneity of nanothread products may deteriorate through competing reaction pathways, and molecular phase transitions can disrupt precursor stacking geometries. Here, we report the formation of well-ordered, double-core nanothreads from compressed α-furil via a unique polymorphic transition pathway that serves to optimize molecular geometry for pressure-induced reaction. At ~1.6 GPa, α-furil transforms to the photoactive trans-planar conformation, which was previously theorized but not observed. Crystalline packing of the trans-planar structure provides closely overlapping molecular stacks that result in topochemical-like Diels-Alder cycloaddition reactions between furan rings upon further compression. The controlled reaction pathways on both sides of the molecule produce two linked “cores” of chemically homogenous nanothreads, and successive nucleophilic addition reactions crosslink a large fraction of the diketone bridge between monomers.

Messenger RNA (mRNA) display is being increasingly adopted for peptide drug candidate discovery. While many conditions have been reported for the affinity enrichment step and in some cases for peptide modification, there is still limited understanding about the versatility of peptide—puromycin—mRNA/cDNA (complementary DNA) complexes. This work explores the chemical stability of mRNA/cDNA hybrid complexes under a range of different fundamental chemical conditions as well as with peptide modification conditions reported in an mRNA display setting. We further compare the stability of full complexes originating from two different mRNA display systems (RaPID and cDNA-TRAP). Overall, these complexes were found to be stable under a broad range of conditions, with some edge conditions benefitting from encoding directly in cDNA rather than mRNA. This should allow for more and broader exploitation of late-stage peptide modification chemistry in mRNA display, with confidence regarding the stability of encoding, and potentially better hit-finding campaigns as a result.
