Description:

Western corn rootworm is one of the most dangerous pests of maize, and both the larvae and the imagoes thereof may cause significant damage to the plants. The options of controlling these pests have recently become highly limited, thus creating a great demand for new control methods complying with sustainable plant protection. These requirements are met by the natural enemies of these pests, such as entomopathogenic nematodes (e.g. Heterorhabditis bacteriophora, Gerritsen, 1994). The objective of this study was to determine whether the viability and larvicide effect of a single injection into the soil of 2 billion nematodes using various amounts of water (50, 100 or 200 L/hectare) was maintained even with the lower quantities. Our studies proved that the entomopathogenic nematodes retain their viability and larvicide effect when applied using 50 L/ha of water. The efficacy of the biological agent did not differ from that of Force 1.5G, a product containing Tefluthrin as active ingredient, which was used as positive control.

Aspects concerning the observation process modelling in the framework of cognition processes

Claudiu Radu Pozna Radu Emil Precup

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2012-04-17

Volume: 9

Issue: 1

Page Range: 203-223

Description:

This paper presents results concerning the observation process modelling in the framework of cognition processes which belong to a new pattern of human knowledge. The cultural origin of the patterns is analyzed in terms of philosophical, psychological and linguistic points of view. A scenario concerning a robot integrated in a cognitive system is given in order to test the theoretical approaches. The definitions of signatures and of signature classes are given as one of the first steps in an alternative modelling approach to the observation process. An example that deals with the observation process modelling is offered.

The Role of Economic Growth and FDI in Ecological Footprint and the Load Capacity Factor: Evidence From Türkiye

Zafer Adali Ayyüce Memiş Karataş Xin Zhao İlkay Güler Gökçen Aydinbaş

Publication Name: Acta Montanistica Slovaca

Publication Date: 2025-01-01

Volume: 30

Issue: 1

Page Range: 193-208

Description:

Proposed sustainable economic development and growth have been among the leading and desired objectives of policymakers. Thus, various investigations have been conducted, considering different social, political, and economic factors to lessen environmental degradation and improve biocapacity. Within this context, Türkiye is one of the most essential cases because of its location and role in the global supply chain, emerging countries' members, and the severity of the environmental situation. Thus, the study employs the Fourier ARDL, FADL co-integration tests, FMOLS estimations with Fourier Terms, and Fourier Toda-Yamamoto analysis to investigate the role of economic growth and FDI in ecological footprint and the load capacity factor along with considering some control variables over the period between 1982 to 2021. As a result of the investigations, it is concluded that the economic growth, the FDI, and the remaining variables do not promote impact the load capacity factor. However, the considered variables pressure the environment when the ecological footprint is regarded as the environmental indicator, and the pollution haven hypothesis holds for Türkiye. To reverse and mitigate the harmful effects of economic activities, efforts, and policies should be made toward environmentally friendly forms of production, trade, FDI, and renewable energy sources.

Effect of junction type on the vibroacoustic response of a system of plates

Dániel Feszty Marcell Treszkai

Publication Name: Proceedings of Inter Noise 2021 2021 International Congress and Exposition of Noise Control Engineering

Publication Date: 2021-01-01

Volume: Unknown

Description:

Modelling of junctions is one of the most challenging tasks in vibroacoustics, especially for Statistical Energy Analysis (SEA), where the results heavily depend on the damping (DLF) and coupling loss factors (CLF). Also, it is an interesting question to determine that to what extent does the DLF or CLF contribute to the overall vibroacoustic characteristics of a structure? The aim of this paper is to investigate via measurements and SEA simulations the effect of the ratio of DLF and CLF on the response of a system for various junctions, such as riveting, bolting, line and point welding, between two steel plates. Loss matrices are determined experimentally by the Power Injection Method in the 200-1600 Hz frequency range. The simulation was performed in the ESI VA One software by using its analytical CLF formulations and compared to experimental data. For the reference case, a bended plate structure was considered, representing an ideal junction between two subsystems. This was equipped with damping foils to ensure the same weight and then compared to the results from other joints. Results showed that increasing the CLF could be more effective than focusing on increasing the DLF.

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.

Understanding intentions towards seeking university-business partnerships – analysing four european cases

Zsolt Kohus Katalin Czakó Zoltán Baracskai

Publication Name: Journal of International Studies

Publication Date: 2021-01-01

Volume: 14

Issue: 2

Page Range: 228-244

Description:

It is an important economic and social issue for universities to provide value for their communities by seeking and maintaining partnerships with local firms. This paper analyses institutions of different national economies. It systematises the differences and similarities in the communication of universities aiming to partnering. To this end, we present four European cases from France, Germany, Hungary and Poland. The methodology lies in its grounded theory approach to a continuous multi-case analysis. Our hypotheses are as follows: There are role differences of universities in the observed cases (H1). There are different understandings behind fruitful university-business partnerships (H2). The rate of diversification in local industries effects the presence and types of university services and business partnering activity (H3). Data hubs were extracted from institutional communications and integrated with local economic data input. The novel approach of applying the grounded theory supports complex observation. Notions of fruitful partnerships are institution-specific, but we identify two opposite perspectives of strategies to run efficient university-business partnering. The structure of the local industrial environment, research output and university-business interactions have definable mutual effects.

Correspondences between Hungarian women's marital names and the traditional family schema

Judit Baranyiné Kóczy

Publication Name: Cognitive Linguistic Studies in Cultural Contexts

Publication Date: 2021-01-01

Volume: 14

Issue: Unknown

Page Range: 151-183

Description:

A marital name makes a statement about women's cultural values with respect to their family schemas. In Hungary, adopting the husband's full name by marriage is no longer required, thus women have the opportunity to choose from seven different name structures. The paper aims to uncover the motivations behind women's preference for marital name structures as influenced by the traditional family schema that they maintain in their background. Data for this analysis is extracted from a questionnaire distributed to 533 women, which seek to obtain information on key elements of the traditional family schema. Results do not reveal a direct correlation between the selection of marital names and any single component of the traditional family schema; however, overall the results of the survey outline a systematic correspondence between marital names and women's conformity or non-conformity to the traditional family schema. In conclusion, the various marital name structures reflect diverse family schemas, in particular, they are representatives of Hungarian women's different extent of adherence to the traditional family schema.

Experimental results of sliding and welding tests in a novel construction method for steel-concrete composite bridges

János Szép Daniel Gosztola

Publication Name: Fib Symposium

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: 923-930

Description:

The primary objective of this study is to introduce a novel construction method used for steel-concrete composite bridges. Throughout the article, domestic and international solutions and practices will be provided for various girder-prefabricated deck slab connections, as well as construction methods for steel-concrete composite bridges. The new bridge construction technology involves the construction of a prefabricated deck slab on-site, which is moved into its final position on the main girders. During prefabrication, a stud plate is positioned within the formwork, facilitating the sliding of the deck slab elements onto the girder. The upper flange and stud plate are joined by welding following the sliding of the deck parts. The key challenge for this technology is achieving a sufficiently low friction coefficient between the stud plate and the flange using a suitable material. However, it is imperative to identify a material that can be compatible with the welded connection. Laboratory experiments were carried out to investigate the effect of materials on the friction coefficients between steel plates and the welding of the connection. The ideal material has been identified through experiments to lower the coefficient of friction to 4-8% while the welded joint can be achieved.

The effect of image feature qualifiers on fuzzy colorectal polyp detection schemes using KH interpolation - Towards hierarchical fuzzy classification of coloscopic still images

Brigita Sziová László T. Kóczy Szilvia Nagy

Publication Name: IEEE International Conference on Fuzzy Systems

Publication Date: 2018-10-12

Volume: 2018-July

Issue: Unknown

Page Range: Unknown

Description:

Previous studies showed that intensities, intensity variation, edge densities, structural entropies of colonoscopy images and their wavelet transforms are good candidates for being selected as antecedents in fuzzy decision methods using KH interpolation for determining whether an image segment contains colorectal polyp segment. In the present consideration, we check which possible antecedent dimensions need interpolation, whether the average and variation of the gradients makes the classification more effective and whether some of the features can be omitted for some classes of images. The method is tested on three available databases consisting of images of three different resolutions, and according to the results, different resolutions, different types of polyps require different classification schemes, thus a hierarchical decision system needs to be built.
