Description:

Cercospora-leaf spot (CLS) of sugar beet, caused by Cercospora beticola Sacc., is a major foliar disease of sugar beet in all sugar beet growing areas, worldwide, causing up to 50% yield loss. The disease is now dominant in almost all sugar beet growing areas of Europe, including Hungary. The use of fungicides has been being an integral part of the control of CLS of sugar beet. In recent decades, resistance of C. beticola to fungicides belonging to different groups of active substances has been described in many countries worldwide, including Hungary. The picolinamides are a new distinct group of fungal respiration inhibitors (QiI – FRAC Group 21) promise to be a good alternative in the management of fungicide resistance in crops. The florylpicoxamid fungicide were tested and evaluated over two seasons, in vegetation period of 2020 and 2021 for controlling CLS of sugar beet in Hungary. This fungicide was applied as straight formulated product at a range of dose rates, and they showed very effective control of CLS compared to the untreated control check plots and the reference fungicide products difenoconazole and epoxiconazole. All tested dose rates of florylpicoxamid provided effective control of against CLS of sugar beet. The area under the disease progress curve values (AUDPC) was significantly correlated with yield decrease, but AUPDC did not correlated with sugar content of the roots. Additionally, the results showed in two investigated years, the efficacy of florylpicoxamid for the control on CLS of sugar beet crop.

Description:

Recently, the development of functional foods enriched with plant phenolic compounds attracted the attention of researchers due to their favorable health properties. Naringin (NAR) and hesperidin (HES) are two main bioflavonoids available in high concentrations in citrus (CTS) fruits, including juice processing by-products like peel, membranes, and seeds. In general, NAR and HES offer potential health benefits in various diseases including diabetes mellitus, certain types of cancer, and obesity. However, to take advantage of the benefits of flavonoids in CTS, researchers must consider various factors since the development of enriched food is valueless if the bioactive compounds are not stable in the food matrix or are not absorbed appropriately throughout the digestive system. This study presents the sensory, physicochemical, and organoleptic properties of CTS-enriched dairy products produced by different technologies. This paper also includes the extraction methods, encapsulation technologies, and beneficial effects of NAR and HES. Overall, results supported that incorporating HES and NAR improves the antioxidant properties and, in some cases, the consumer acceptance of dairy products. In the future, the application of encapsulation technologies will probably come to the fore in the functional food industry, since encapsulation is used to mask unpleasant feelings during eating, such as the bitter taste of CTS flavonoids.

Basque identity and soccer

Róbert Győri Szabó

Publication Name: Soccer and Society

Publication Date: 2013-07-01

Volume: 14

Issue: 4

Page Range: 525-547

Description:

Football is regarded as one of the defining elements of the local national identity in Spain - a country with diverse historical nationalities. The game serves as the means for a nationality to dissociate from the majority-controlled state. The importance of national identities to be found on the territory of Spain is central to any worthy understanding of the history of football up to the present day, and it is especially true in the case of Basque football. Sport, and especially football, plays an important role in emphasizing the Basque national identity in all the Basque regions, and it is a special manifestation of their political beliefs. As this essay tries to argue, the game has become an integral part of Basque national culture while the football clubs and national teams have assumed political importance. The Basques have their own national teams, i.e. clubs, whose teams represent the Basque nation as also the country Euskadi. Thus, the essay aims to examine the relationships between football and Basque national identity in a historical perspective. © 2013 Copyright Taylor and Francis Group, LLC.

The concepts of state responsibility and liability in nuclear law

Gábor Kecskés

Publication Name: Acta Juridica Hungarica

Publication Date: 2008-06-01

Volume: 49

Issue: 2

Page Range: 221-252

Description:

The legal concept and the doctrinal theory of state responsibility and liability have been in the focus of public international law for a long while. By means of domestic legislation, national law-regardless of the relevance of the international legal framework-governs the system of civil liability within the area of civil law of each state. Whereas, as opposed to the framework of civil liability governed by diverse domestic rules, exclusively a standard regulation framed at an inter-state level can secure a uniform system of state liability. The issue of state responsibility for nuclear damages raises specific questions to be examined in the framework of general international regulations (e.g., Conventions adopted within the area of nuclear law) related to responsibility and liability. Thus, answering or the clarification of these specific pivotal questions within the scope of public international law shall be our starting point, which may also entail the modification of the matter of state responsibility and liability (not only in the concerned branch of law). © 2008 Akadémiai Kiadó.

Description:

The aim of our research was the identification of nosocomial pathogens found in the internal drinking water network of healthcare facilities which can cause infections in hospitals. In this study, the composition of bacterial communities from the internal water network of a health institution in Győr (Hungary) was examined using standard culture-based methods. Identification of the bacterial isolates was performed using Analytical Profile Index (API). Members of 13 bacterial taxa were recovered from a multi-storey healthcare institution. 10 species were identified via API20E and API20NE testing, out of which isolates of genera Aeromonas, Pseudomonas and Sphingomonas were found in the highest proportion on different media. These bacteria can cause nosocomial infections in clinical environments, leading to serious illnesses mainly in patients, as they may have multiresistance genes. In addition, Legionella species were also identified in the water samples, which are also known to be nosocomial pathogens, since they can be spread with aerosols in hospital environments and can cause severe respiratory diseases in immunocompromised individuals.

Cultural Influence on Sustainability Discourse: A Comparative Analysis of CEO Letters in the Cosmetics and Fashion Industry

Lívia Ablonczy-Mihályka Zsuzsanna Pálffy

Publication Name: Journal of Ecohumanism

Publication Date: 2024-08-03

Volume: 3

Issue: 4

Page Range: 2779-2792

Description:

The national cultural background of a company's founders and managers significantly influences corporate culture and communication. Over the past two decades, the link between culture and sustainability practices has been demonstrated, including how sustai nability embeddedness is reflected in CEO letters. This study examines if companies in the cosmetics and fashion industries reveal cul tural influences on sustainability in their CEO letters. These letters, the most influential part of annual reports, convey the CEO's vision, operations, and performance. Using quantitative and qualitative content analysis, the research investigates whether national culture influences the content of CEO letters by analysing letters from 15 companies across 10 countries. The study found no statistically significant correlation between Hofstede's cultural dimensions and sustainability narratives in CEO letters. However, feminine cultures tend to have stronger sustainability orientations. These findings suggest that companies should adapt their sustainability communication to align with local cultural values, thereby enhancing stakeholder engagement, particularly for multinational beauty and fashion companies.

Influence of imperfections in the buckling resistance of steel beam-columns under fire

Samer Nemer F. Papp

Publication Name: Pollack Periodica

Publication Date: 2021-08-01

Volume: 16

Issue: 2

Page Range: 1-6

Description:

This paper presents an investigation on the influence of structural imperfections on the ultimate load capacity of steel welded beam-columns with class 4 cross-section under elevated temperatures. This is done by considering different amplitudes for the global and local (plate) imperfections, and different residual stresses distributions available in the literature. To this purpose, a geometrically and materially non-linear finite element model using Abaqus software has been used to determine the buckling resistance of a steel welded beam-column at elevated temperatures, using the material properties of EN1993-1-2. The imperfection sensitivity of beam-columns is reported: the influences of the amplitudes of the geometric imperfection and the patterns of the residual stress on the load capacity are compared.

Residual elimination algorithm for solving linear equations and application for sparse systems

B. Török Gyozo Molnárka

Publication Name: ZAMM Zeitschrift Fur Angewandte Mathematik Und Mechanik

Publication Date: 1996-12-01

Volume: 76

Issue: SUPPL. 1

Page Range: 485-486

Description:

A new direct algorithm for solving linear system of equations will be presented. Short theoretical background and analysis of the proposed method will be given. We formulate an optimized version of the proposed algorithm, which also works for sparse matrices. The complexity of the suggested algorithm for full matrix systems is n3/3 H- O(n2) where n is the dimension of the problem. The numerical experiments show that some versions of the residual elimination algorithm can be competitive with the Gaussian elimination both in complexity and precision. Moreover the sparse linear solver based on this algorithm has some advantages in parallel environment.

Investigating Combustion Process of N-Butanol-Diesel Blends in a Diesel Engine with Variable Compression Ratio

Kristóf Lukács György Szabados Ákos Bereczky

Publication Name: Clean Technologies

Publication Date: 2021-09-01

Volume: 3

Issue: 3

Page Range: 618-628

Description:

The search for alternative fuels for internal combustion engines is ongoing. Among the alternatives, plant-based fuels can also be mentioned. Alcohol is not a common fuel for diesel engines because the physical and chemical properties of the alcohols are closer to those of gasoline. In our research, the combustion properties of diesel-n-butanol mixtures have been investigated to obtain results on the effect of butanol blending on combustion. Among the combustion properties, ignition delay, in-cylinder pressure, and heat release rate can be mentioned. They have been observed under different compression conditions on an engine on which the compression ratio can be adjusted. The method used was a quite simple one, so the speed of the engine was set to a constant 900 rpm without load, while three compression ratios (19.92, 15.27, and 12.53) were adjusted with a fuel flow rate of 13 mL/min and the pre-injection angle of 18◦ BTDC. Blending butanol into the investigated fuel does not significantly affect maximal values of indicated pressure, while much more effect on the pressure rising rate can be detected. Furthermore, heat release rate and ignition delay increased at every compression ratio investigated. Despite the low blending rates of butanol in the mixtures, butanol significantly affects the combustion parameters, especially at high compression ratios.
