Thermochemistry of antioxidant action of isoflavones and their deprotonated forms in aqueous solution: hydrogen or electron transfer?
Authors: Biela Monika , Kleinová Andrea , Klein Erik 
Published: May 2022

Abstract
Isoflavones possessing several weak acidic hydroxyl groups can undergo successive deprotonations in aqueous solutions. Therefore, their antioxidant properties cannot be ascribed only to the neutral forms but also to corresponding phenoxide anions. It was already confirmed that isoflavones prefer the formation of dianions in aqueous solution. For eight isoflavones and their preferred (poly)deprotonated forms, thermochemistry of hydrogen atom transfer and electron abstraction was studied in terms of corresponding reaction enthalpies, i.e., O—H bond dissociation enthalpies and ionization potentials. Our results clearly indicate that the increase in negative charge causes significant drop in ionization potential and bond dissociation enthalpy. On the other hand, proton affinities show the opposite trend. Thus, it is unfeasible to find a generally valid trend for dianions — corresponding reaction enthalpies strongly depend on the structure of isoflavone, especially on the number/positions of OH groups.
Data Mining Approach in Diagnosis and Treatment of Chronic Kidney Disease

Abstract
Chronic kidney disease is a general definition of kidney dysfunction that lasts more than 3 months. When chronic kidney disease is advanced, the kidneys are no longer able to cleanse the blood of toxins and harmful waste products and can no longer support the proper function of other organs. The disease can begin suddenly or develop latently over a long period of time without the presence of characteristic symptoms. The most common causes are other chronic diseases – diabetes and hypertension. Therefore, it is very important to diagnose the disease in early stages and opt for a suitable treatment - medication, diet and exercises to reduce its side effects. The purpose of this paper is to analyse and select those patient characteristics that may influence the prevalence of chronic kidney disease, as well as to extract classification rules and action rules that can be useful to medical professionals to efficiently and accurately diagnose patients with kidney chronic disease. The first step of the study was feature selection and evaluation of its effect on classification results. The study was repeated for four models – containing all available patient data, containing features identified by doctors as major factors in chronic kidney disease, and models containing features selected using Correlation Based Feature Selection and Chi-Square Test. Sequential Minimal Optimization and Multilayer Perceptron had the best performance for all four cases, with an average accuracy of 98.31% for SMO and 98.06% for Multilayer Perceptron, results that were confirmed by taking into consideration the F1-Score, for both algorithms was above 0.98. For all these models the classification rules are extracted. The final step was action rule extraction. The paper shows that appropriate data analysis allows for building models that can support doctors in diagnosing a disease and support their decisions on treatment. Action rules can be important guidelines for the doctors. They can reassure the doctor in his diagnosis or indicate new, previously unseen ways to cure the patient.

Abstract
Ketosis is a major metabolic disorder that can lead to huge economic losses in postpartum dairy cows by influencing milk production and reproduction performance. Therefore, it is very important to understand the characteristics and significance of plasma GH levels and dynamic changes in postpartum dairy cows for finding pathogenesis of subclinical ketosis (SK). The present study aimed to determine the role of growth hormone (GH) from the onset of SK to the fifth week postpartum and to explain the variations in GH, and metabolic markers namely, β-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA) and glucose (GLU) at early and later SK stages in postpartum Holstein cows. A 5-wk test and an intraday 12-h test were conducted in postpartum Holstein cows. Both tests were carried out every three hours from 10:00–22:00 for 7–14 days postpartum (12-h test: n = 16) to determine plasma concentrations of GH, BHBA, NEFA and GLU. The 5-wk test results showed that GH, BHBA and NEFA concentrations were significantly higher in the SK group during the five-weeks postpartum (p < 0.01); GLU concentration was significantly lower in the SK group (p < 0.01). Intraday 12-h test results revealed that the feeding time affected the plasma concentrations of GH, BHBA, NEFA and GLU. After 1-h of feeding time, GH concentrations decreased, while BHBA, NEFA and GLU concentrations increased. After 4-h of feeding time GH, BHBA and NEFA had the highest plasma concentrations, and GLU the lowest. In both experiments, GH was positively correlated with BHBA, NEFA, and negatively correlated with GLU. It can be suggested that GH has a potential role in development and aetiology of subclinical ketosis.
Changing Sensitivity of Diverse Tropical Biomes to Precipitation Consistent with the Expected Carbon Dioxide Fertilization Effect

Published: May 2022

Abstract
Global environmental changes have implications for the terrestrial ecosystem functioning, but disentangling individual effects remains elusive. The impact of vegetation responses to increasing atmospheric CO2 concentrations is particularly poorly understood. As the atmospheric CO2 concentration increases, the CO2 acts as a fertilizer for plant growth. An increase in atmospheric CO2 reduces the amount of water needed to produce an equivalent amount of biomass due to closing or a narrowing of the stomata that reduces the amount of water that is transpired by plants. To study the impacts of climate change and CO2 fertilization on plant growth, we analyzed the growing season sensitivity of plant growth to climatic forcing from alpine to semi-desert eco-climatic zones of Ethiopia for various plant functional types over the period of 1982–2011. Growing season 3rd generation Normalized Difference Vegetation Index of Global Inventory Modeling and Mapping Studies (NDVI) was used as a proxy of plant growth, while mean growing season precipitation (prec), temperature (temp), and solar radiation (sr) as the climate forcing. The sensitivities of plant growth are calculated as a partial correlation, and a derivative of NDVI with respect to prec, temp and sr for earliest and recent 15-year periods of the satellite records, and using a moving window of 15-year. Our results show increasing trends of plant growth that are not explained by any climate variables. We also find that an equivalent increase in prec leads to a larger increase in NDVI since the 1980s. This result implies a given amount of prec has sustained greater amounts of plant foliage materials over time due to decreasing transpiration with increasing CO2 concentration as expected from the CO2 fertilization effect on water use efficiency and plant growth. Increasing trends of growth in shallow-rooted vegetation tend to be associated with woody vegetation encroachment.
A Look Into the History of Landscape Research in Czechia. Landscape in Natural and Social Sciences, Attempts at an Interdisciplinary Approach
Authors: Lapka Miloslav , Gottlieb Miroslav 
Published: May 2022

Abstract
Self-reflection is important for every scientific discipline and the study of landscape is no exception. Indeed, landscape is connected in some way to both the natural and social sciences, as well as the and humanities as see in art and architecture.
This review analyses the development of landscape research by scientific institutions in the contemporary Czech Republic. It is an attempt to provide a thematic and historical review of its often very complicated development. The study is organized thematically and a chronological order is used for each topic. The topics covered are: The cultural formation of the “Phenomenon of the Czech landscape”; The formation of the approach to landscape in natural sciences; “Phenomenon of the Czech landscape” in architecture; Landscape in institutionalized form in the Academy of Sciences; Landscape outside the Academy of Sciences, and; “Phenomenon of the Czech landscape” in social sciences.
Archived documents from the former Institute of Landscape Ecology of the Czechoslovak Academy of Sciences, the primary thematic studies of individual authors and secondary studies reflecting the development of the field itself were used for the development of this thematic and historical review. These sources were refined where possible through guided semi-structured interviews with eyewitnesses and written correspondence.
The results show two strong centres of landscape ecology: Institute of Landscape Ecology of the former Czechoslovak Academy of Sciences (ČSAV) in Prague formed out of its forerunners in 1971 which is associated with the name of Emil Hadač and relocated to České Budějovice, where it ceased to exist in 2010. Another centre is set up in Brno at the Geographical Institute of the Czechoslovak Academy of Sciences in Brno at the Mendel University of Brno (Antonín Buček, Jan Lacina).
The cultural character and intertwining natural and cultural components of the landscape play an important role in understanding the specific aspects of the scientific study of landscape in our country. This was the basis of the initial scientific reflections of the forerunners of landscape ecology in biological sciences (Bohumil Němec, Julius Stoklasa), in nature conservation (Jan Svatopluk Procházka) and in architecture (Karel Honzík, Ladislav Žák). This interdisciplinary character of landscape research persists in many institutions and organizations to this day, including the Czech branch of the International Association for Landscape Ecology IALE - CZ.
It is a great paradox of our time that landscape and landscape ecology has ceased to be institutionally represented in the structure of the Czech Academy of Sciences. In conclusion, we ask the question about the reasons for this development and whether landscape research can be restored in the structure of the Academy of Sciences of The Czech Republic.
Improvement of Steerability and Driving Safety of an Electric Three-Wheeled Vehicle by a Design Modification of its Steering Mechanism
Authors: Dižo Ján , Blatnický Miroslav , Melnik Rafał , Karľa Michal 
Published: May 2022

Abstract
Three-wheeled vehicles are transport means which generally combine properties of two-wheeled vehicles (principal motorcycles) and four-wheeled vehicles (standards cars). Three-wheeled vehicles have been designed and manufactured as units which are made up of one front wheel and two rear wheels, powered by an electric drive-train, and referred to in some countries under a non-English term as E-3kolka. These vehicles also comprise a special steering mechanism which improves their overturning stability when driving around curves. However, several tests have revealed certain deficiencies of the steering mechanism, where the main issue included unreliable self-restraining effect of steering wheel straightening after driving around a curve. This may even lead to unacceptable properties of the vehicle. Therefore, the authors of this paper suggest particular technical solutions to eliminate or completely avoid the described negative effects during driving. Proposed designs are mutually compared and a final decision is presented.
Analysis of the possibility of using key-value store NoSQL databases for IFC data processing in the BIM-GIS integration process
Authors: Wyszomirski Michał 
Published: May 2022

Abstract
The article discusses the possibility of using Redis key-value NoSQL database to process building data in different BIM-GIS integration solutions. Whichever data integration model is adopted, it will require an efficient serving of building data in Industry Foundation Classes (IFC) format. The author proposed a method of processing building data in the Redis database to support the process of feeding IFC data to his own concept of an integrated BIM-GIS database. However, other approaches to BIM-GIS integration, including the import of IFC data to CityGML, or the construction of an integrated BIM-GIS solution based on data integration at the application server level or client application in client-server environments, also require an efficient IFC data serving mechanism. This article describes three methods of storing IFC data in a Redis database using different data types and formats. The author conducted performance tests of the proposed methods in the processing of fourteen test BIM models. The article contains detailed results of the model processing tests in the Redis database.

Abstract

This writing aims to find out and analyze the definition of the editorial "certain reasons" as regulated in Article 3 number 15 of the Notary Code of Ethics. The research study uses a normative juridical method with a statutory approach and a conceptual approach. The technique of collecting legal materials uses library research. The results of the study indicate that the definition of "certain reasons" is a reason that is permitted by law. If a violation of this article is committed, it will not affect the authenticity of the deed because the Notary is authorized to make the deed outside the office or outside his domicile while still in the area of ??office. If there is a violation caused by not fulfilling one of the requirements for the authenticity of the deed, it will result in the deed experiencing a decline or being degraded into a deed under the hand.

Abstrak

Penulisan ini bertujuan untuk mengetahui dan menganalisis tentang definisi dari redaksi “alasan-alasan tertentu” sebagaimana diatur di Pasal 3 angka 15 Kode Etik Notaris. Kajian penelitian menggunakan metode yuridis normatif dengan pendekatan perundang-undangan serta pendekatan konseptual. Teknik pengumpulan bahan hukum menggunakan studi kepustakaan. Hasil penelitian menunjukkan bahwa definisi mengenai “alasan-alasan tertentu” merupakan suatu alasan yang di perbolehkan oleh Undang-Undang. Jika pelanggaran terhadap pasal tersebut dilakukan, maka tidak serta mempengaruhi ke autentikkan akta dikarenakan Notaris berwenang membuat akta diluar kantor atau diluar tempat kedudukannya selama masih berada di wilayah jabatan. Apabila terjadi pelanggaran yang disebabkan karena tidak di penuhinya salah satu syarat otentisitas akta maka akan mengakibatkan akta mengalami kemerosotan atau terdegradasi menjadi akta dibawah tangan.

Market Reaction As An Impact Of The Fed Interest Rate Decrease Announcement In Asian And European Areas

ABSTRACT
The announcement of the reduction in the Fed's interest rate on July 31, 2019 is a rare event since 2008. The Fed's rate cut will have a major impact on the global economy and conditions in the capital market.The purpose of this study is to determine whether there is a difference in the average abnormal return around the date of the announcement of the Fed's interest rate hike in Asia and the European region. The sample of this study was 18 emerging market countries' index indices in Asia and Europe with sample collection techniques using purposive sampling. This study uses One Way Anova analysis techniques and One Sample T-test. The results found that there was no difference in the average abnormal return before and after the announcement of the Fed's interest rate increase. This condition shows that markets in the two regions do not react significantly because markets in Asia and the European region are in an efficient condition in the form of half strong, where the market absorbs information quickly and is reflected in stock prices so there is no difference in the average abnormal return in both regions. The absence of a difference in the average abnormal return is also caused by the uncertainty of the global economy making investors more careful in making investment decisions.
