Abstract

Pax Corporis is the first book written in Hungarian that presents in detail human diseases, their etiology and treatment. Ferenc Pápai Páriz had completed the manuscript entitled Pax Corporis in 1687, and it was published 3 years later in 1690 in Kolozsvár. Ferenc Pápai Páriz summarized the knowledge he gained during his studies and accumulated during his personal practice. He did not write this book for the professionals but for those poor people who had no access to physician’s care. This was the reason why Pax Corporis was written in Hungarian. Whereas Pápai’s Latin language scripts – for example his doctoral thesis written in Basel – are known to the international scientific community, the Hungarian language Pax Corporis remained unknown for all who were not familiar with the language. For this reason it also remained neglected that in Pax Corporis Ferenc Pápai Páriz had given a detailed description of all four currently acknowledged cardinal signs of Parkinson’s disease – tremor, rigor, bradykinesia and postural instability – and also of other characteristics of the disease 130 years before James Parkinson. The report on the description of the syndrome of Parkinson’s disease in Pax Corporis was presented to the international professional community in 2009. In the current study we evaluated the international recognition of Ferenc Pápai Páriz as one of the first descriptors of all 4 cardinal signs of Parkinson’s disease. We searched scientific citation databases – Web of Science, Scopus, Google Scholar – and also performed general searches on the web. We found that until April 2018 Pápai Páriz has been cited among those who first described the complete motor syndrome of Parkinson’ disease in Pax Corporis, in many countries of the world from New Zealand to Canada, and also in 16 European countries. Citations appeared in dissertations, scientific publications, textbooks, handbooks, professional websites and other documents. Three centuries after his original Hungarian script, Ferenc Pápai Páriz got his international recognition in medical history as one of the first descriptors of the syndrome of Parkinson’s disease.

Abstract

In our study, we tested the existing and freely accessible soil databases covering a smaller geographical region surveyed and classified according to the Hungarian classification in order to approximate the WRB soil reference groups (RSG). We tested the results and applicability of approximation for the RSG with three different methods on 12 soil profiles. First, RSGs were assigned to Hungarian soil taxa based on results of previous correlation studies, secondly, a freely accessible online database of ISRIC was applied furthermore, and an automated reclassification developed and programmed by us was used, which takes the original soil data as input.

Abstract

In our study we attempt to demonstrate the effects of uninsulated sewage tanks, which are the most important sources of contamination in settlements without sewage systems, on groundwater quality. We compared the results of measurements carried out before and one and a half years after the construction of the sewage system. We established 3 m deep monitoring wells within a 25 m radius of a sewage tank, which were then sampled, and the level of groundwater was recorded. The 3D model constructed on the basis of the saturated zone shows that the effluent wastewater formed a groundwater level dome with a height of more than 1 m. After the sewage tank was taken out of use the difference between the highest and lowest groundwater levels decreased to a few centimetres. In our study we investigated the spatial distribution of NH4 + (ammonium). Using the 3D model we were able to precisely determine the volume of water bodies with different levels of contamination. In an approximately 25 m3 water body, in the immediate environment of a sewage tank in use we detected NH4 + at a concentration which was characteristic of undiluted wastewater (>90 mg·dm−3). After the sewage tank was taken out of use, the concentration in its immediate environment decreased by more than 50%, although almost everywhere in the modelled area concentrations were measured above the limit value. Based on the above, we can conclude that the cleaning process has started, but the complete decontamination of the groundwater will take several years.

Abstract

In our study, by investigating reambulated soil profiles from the Nagy-Sárrét region in Hungary, we attempt to determine the extent of changes which have occurred due to effects which impacted the landscape in terms of the soil chemistry properties of soil profiles exposed during the Kreybig soil survey more than 70 years ago. Based on the results, in the areas used as grassland, we observed a decrease in pH and an increase in the humus content of the topsoil. The increased CaCO3 following the chemical improvement of the soil which was used as cropland is still characteristic of the area. During the past decades, the investigated soils have been affected by significant changes with regard to water management, which have also modified the investigated parameters. We have classified the reambulated soil profiles among the Solonetz, Vertisol, and Gleysol reference groups based on the World Reference Base of Soil Resources (WRB) diagnostic system.
