BEYOND FIATFALVA DAM ARE NO TROUT, NOR WEALTHY MEN

Andor Wesselényi-Garay

Publication Name: Metszet

Publication Date: 2024-01-01

Volume: 15

Issue: 5

Page Range: 26-33

Description:

Commenting on the state of contemporary architecture in Transylvania leads to certain contradictions, a falling ethnic Hungarian population, abandoned rural buildings, palaces, barns and churches. Maybe there are no contemporary buildings, only restoration projects, or the act of restoration acts as a contemporary indicator of new beginnings. Elements of the design being executed in stainless steel or glazed installations are signs of high-tech architecture.

Szonja Jenei Sándor Remsei Szilvia Módosné Szalai

Publication Name: Hrvatski Geografski Glasnik

Publication Date: 2024-01-01

Volume: 86

Issue: 2

Page Range: 5-17

Description:

In the 20th century, transportation heavily relied on hydrocarbons. Currently, the initial transition to electric propulsion is being witnessed.There's an ongoing debate among technical experts regarding its effectiveness alongside the start of battery production. Our research focuses on the labour market impact of companies operating in battery manufacturing, component production, and disposal in Hungary, as well as the opinions of local residents regarding the establishment of these organizations. Our research aims to track the differences and similarities between the governmental standpoint and the population's views. Hungary stands out for its rapid industrialization, focusing on enhancing GDP and job creation.The population is concerned about employing immigrant workers and potential battery production and disposal accidents. Our qualitative study adheres to the European Green Deal principles, including insights on battery manufacturing from transportation experts, manufacturers' associations, and environmentalists. Our quantitative research shows a preference for living at an unrealistic distance from such facilities. Many citizens advocate for the cessation of battery factory operations or investments, a stance mainly due to limited public awareness. Middle-aged individuals exhibit the most fear, and we correlate our findings with societal facts and negative incidents. To mitigate these tensions, mass education, tighter regulation, and increased sanctions are recommended.

Publication Name: Studies in Fuzziness and Soft Computing

Publication Date: 2024-01-01

Volume: 427

Issue: Unknown

Page Range: 15-23

Description:

An assessment of local needs and conditions is essential to support an efficient waste management system, which can be used to select the components and waste management options that best meet these circumstances and their resource requirements. Each of these activities requires careful planning, but the model of sustainable municipal waste management offers a comprehensive interdisciplinary framework. The aim of the research is to develop and present a methodology as an environmental engineering problem that can be applied in practice to evaluate the sustainability of regional municipal waste management systems. As a result of the research, an integrated and interdisciplinary approach will be developed that can be effectively applied at regional level and give an accurate picture of the actual evolution of the role and impact of the waste management planning process and its implementation.

The Effect of Rectangle Shaped Cutouts of Corrugated Paperboard Packages on Compressive Strength of Boxes

Péter Böröcz Lajos Fehér

Publication Name: Advances in Transdisciplinary Engineering

Publication Date: 2024-01-01

Volume: 59

Issue: Unknown

Page Range: 81-87

Description:

Corrugated paperboard boxes are widely used as packaging in logistics processes. Corrugated boxes must have adequate strength to ensure proper protection of the product. In many cases, the product will require cutouts in the side walls of the boxes. These significantly affect the strength behavior of the box which can be determined by measurements and various models. The aim of this study is to determine the compressive strength of corrugated cardboard boxes of different sizes and different rectangle shaped cutouts formed on them. Five different box dimensions and five different cutout rates were investigated. Box compression tests were carried out to obtain the compression force result of the boxes. The results of these measurements were compared with the box compression force estimation formulas. Two types of McKee formula were used for the comparison that are commonly used in industry. The complete and the simplified McKee formulas are the used models in this study. The constant parameters for both McKee formulas was calculated for each cutout rates. For higher cutout ratios the accuracy of both the simplified and the complete McKee formula increases. In three groups at 0%, 4% and 16% cutouts the fitted complete and simplified McKee formulas predict the BCT results with significant differences. It can be observed that neither the complete nor the simplified McKee formula is able to account for changes in compression force due to variations in box size for any cutout category.

Description:

Naringin is a flavonoid found primarily in citrus species with especially high concentrations being present in grapefruit (Citrus paradisi), bitter orange (Citrus aurantium), and pomelo (Citrus grandis). Because of its many positive effects on human health, naringin has been the focus of increasing attention in recent years. Recently, conventional extraction methods have been commonly replaced with unconventional methods, such as ultrasound-assisted extraction (UAE) and other, more eco-friendly extraction methods requiring little-to-no environmentally harmful solvents or significantly less energy. Naringin analysis is most commonly done via high-performance liquid chromatography (HPLC), and ultrahigh-performance liquid chromatography (UHPLC) coupled with a mass spectrometer (MS) or a photodiode array (DAD) detector. The aim of this review is to provide an overview of recent trends developments in the extraction, sample preparation, and liquid chromatographic analysis of the compound originating from citrus fruits or their products.
