Flow characteristics of the Hornád River and the anthropogenic impact of the Ružín dam for the period 1973–2020

The aim of the study is to analyse the monthly and annual variability of the flow of the Hornad River in the years 1973–2020. The research showed that an upward trend in annual air temperature, precipitation and flows was recorded throughout the catchment area. The analysis of the annual Richard-Baker Index (RBI) and flow variability (Cv) showed a clear downward trend in the variability indexes Cv and Richard-Baker Index in the analyzed multi-year period only at the Kysak station, which is located downstream of the dam. No such changes were observed at the remaining Margecany and Spisska Nova Ves stations, which are located above the dam. The analysis of average monthly Richard-Baker Index values over the course showed greater variation. Between 1973 and 2020, the Richard-Baker Index values ranged from 0 to 0.49 at the Spisska Nova Ves and Margecany hydrological stations, while at the Kysak station, the Richard-Baker Index ranged from 0 to 0.57, indicating large changes in short-term flows. The maximum Richard-Baker Index value occurred in June 1973 (0.57) at the Kysak station. At the hydrological stations above the Ruzin reservoir, the maximum RBI values were recorded in as well as in July 2008 (0.49) at the Margecany station (0.49) and at the Spisska Nova Ves station (0.48), which was the result of very high precipitation (above 170 mm during a month). The values of the Richard-Baker Index at the Kysak station depended on the possibility of water retention in the Ružín I and Ružín II reservoirs and flow control below the dam.

Osudy jezuitov v Spišskej Novej Vsi v časoch druhej svetovej vojny

After the First Vienna Award and the occupation of southern Slovakia by the Hungarians in 1938, the Jesuits from Košice had to move from the newly built house to a new residence in Spišská Nova Ves. The small community repaired the church and the habitation in which it lived. The order took over the rights and duties of the vicariate, so it had to teach religion in the city and its surroundings. The Jesuits often had to deal with personnel issues and especially the problematic figure of Father Ján Guga, who had a close relationship with the Orthodoxia and Russia. In the city, they watched the movements of the troops and experienced the atmosphere of war. The most unpleasant situations were connected with the persecution and deportation of the Jewish population, whom the superior of the house, Štefan Kramár, tried to help by baptizing them. The documents of the house were preserved in the Michal Lacko´s Centre of Spirituality East-West, where they are stored, only until August 1943. For this reason, we only know detailed information about the life of the Jesuits in Spišská Nová Ves until this period.

The Slovak “Narcissus” with Croatian roots. Rudolf Sloboda, a writer

Rudolf Sloboda is one of the brightest and most distinctive writers of the generation of the Slovak “sixties”. He was born and lived most of his life in the village of Devinska Nova Ves near Bratislava with a predominantly Croatian population. Sloboda is the author of dozens of works, including novels, stories, short stories, essays, poems, plays, film scripts. In his work, he was based on the original “egocentric” vision of reality and the confessional-monologue type of narration. The themes of his largely autobiographical prose and drama were complex, often painful relationships between people, crisis states of the personality — everything he faced in his own life. The main space of Sloboda’s books is his native village, with its constants and inevitable transformation. The novels of the writer, first of all — “The Narcissus” (1965), “The Reason” (1982) and “The Blood” (1991), reflect the most important stages in the life and mental wavering of the author and his hero: the early youth marked by entering into an unknown social environment and his first erotic experiences; the maturity with family problems and setbacks, psychological crisis; approaching the old age with the extinction of feelings and desires, that lead to inner emptiness. The universal sound of “private” statements about the existential problems of a person, the artistic persuasiveness, originality and recognizability of his style — all this makes the works of Rudolf Sloboda a part of the Gold Reserve of the modern Slovak literature.

Ozonation: effective way for removal of pharmaceuticals from wastewater

The objective of the presented paper is to characterize the effectiveness of the removal of pharmaceuticals from wastewater during ozonation in laboratory-scale conditions. Almost 100 pharmaceuticals and their metabolites from different therapeutic classes were studied in effluent from the wastewater treatment plant, Devinska Nova Ves, used for ozonation. Telmisartan, diclofenac, and fexofenadine were found at the highest concentrations (1800 ng/dm3, 680 ng/dm3, and 620 ng/dm3, respectively). The concentrations of another 13 pharmaceuticals and metabolites exceeded 100 ng/dm3, and the rest of the compounds were below 100 ng/dm3. These water samples underwent ozonation in intervals of 0–10 min. The flow of ozone during the test was 50 mg O3/min. The results show that the removal of pharmaceuticals is significant after the first minute of ozonation, when most of the studied compounds were below the limit of quantification. The total concentration of the studied compounds after the first minute decreased to 190 ng/dm3 (97.2% removal efficiency). More than 99% removal efficiency was achieved after 10 min of ozonation.

Saint Joseph and Baby Jesus by Valentin Metzinger and Other Paintings from the Strahl Collection in the Museum of Arts and Crafts in Zagreb

Karl Ritter von Strahl (1850−1929) was the last owner of the renowned collection of paintings and art objects kept in his castle of Stara Loka (Altenlack) near Škofja Loka in Carniola. In 1929, Strahl sold 32 paintings to Stanko Senečić, an antique dealer from Nova Ves in Zagreb. In the Museum of Arts and Crafts in Zagreb, there are five paintings of hitherto unknown provenance, which undoubtedly originate from the Strahl Collection. The paper discusses the circumstances of Senečić’ s purchase and the earlier provenance of the five paintings. Furthermore, different paths by which the paintings came to the museum in Zagreb are analyzed. As previous research of the interwar art market in the Kingdom of Serbs, Croats, and Slovenes (later Kingdom of Yugoslavia) has shown that Croatian private buyers and professional antique dealers visited regularly the sales of castle and manor furnishings in interwar Slovenia, we can assume that there are more art heritage items originating from Slovenia in present-day Croatian public and private collections, awaiting an analysis of their provenance.

Monitoring of helium and carbon isotopes in the western Eger Rift area (Czech Republic): Relationships with the 2014 seismic activity and indications for recent (2000–2016) magmatic unrest

Abstract We report new data of the regional distribution pattern of total gas compositions as well as He and CO2 isotopic compositions from 25 gas exhalations in the western Eger Rift and its surroundings. Additionally, the first time-series data from gas exhalations in a clay pit within the Cheb Basin (CB) are given. At 21 degassing locations, the first data were obtained >20 years ago. From 7 locations within the degassing center CB and from 3 degassing sites belonging to the Marianske Lazně (ML) degassing center, neon and argon isotope compositions were determined also. CO2 is the major component at all degassing sites. The δ13C values display a small range (−1.7 to −5.1‰) and the 3He/4He ratios vary from 1.9 to 5.9 Ra. The highest 3He/4He ratios are found at locations along the Pocatky-Plesna Fault Zone, followed by the degassing site in the clay pit on the Nova Ves Fault and the locations on the ML fault at the edge of the CB. Although gas flow and CO2 concentrations in all degassing centers are very high, the fractions of mantle-derived helium are different, with presently up to 94% (in relation to the SCLM 3He/4He of 6.32 Ra) in the CB, up to 73% in the ML and up to 35% in the Karlovy Vary degassing center. At the locations in the eastern part of the CB a clear, progressive increase of the 3He/4He ratio has been observed since the first sampling campaigns there in 1993 and 1994, whereas at the other degassing sites the helium isotope ratio remained essentially the same. The progressive increase of the 3He/4He ratio in the eastern part of the CB, together with further short-time increases up to 6.3 Ra at one location (Bublak) before both the 2000 and 2008 earthquake swarms, indicate an ongoing magmatic process beneath this area, which seems to be associated with the occurrence of seismicity. The CB is located close to the Nový Kostel focal zone where since the beginning of our investigations four strong periods of seismicity (with magnitudes >3) occurred. The latest gas data confirm our earlier findings: time-series studies showed that in relation with seismic events, decreased 3He/4He ratios were repeatedly observed due to admixed seismically released crustal helium. Presently, the eastern part of the CB is the most active non-volcanic region in the European Cenozoic Rift System, with gas signatures similar to those found in free mantle-derived gases from the East African Rift system.

Geckos from the middle Miocene of Devínska Nová Ves (Slovakia): new material and a review of the previous record

New species of a gecko of the genus Euleptes is described here—E. klembarai. The material comes from the middle Miocene (Astaracian, MN 6) of Slovakia, more precisely from the well-known locality called Zapfe`s fissure fillings (Devinska Nova Ves, Bratislava). The fossil material consists of isolated left maxilla, right dentary, right pterygoid and cervical and dorsal vertebrae. The currently known fossil record suggests that isolation of environment of the Zapfe`s fissure site, created a refugium for the genus Euleptes in Central Europe (today, this taxon still inhabits southern part of Europe and North Africa—E. europea), probably resulting from the island geography of this area during the middle Miocene. The isolation of this territory might have facilitated allopatric speciation.

Residentialization of Public Spaces: Bratislava Example

The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link – residentialization.

Numerical modelling as a tool for optimisation of ground water exploitation in urban and industrial areas

Abstract The paper presents an approach to flow and transport modelling, which has been an important tool for the development of protection options for the important groundwater resource of the City of Ostrava in the Czech Republic. The resource is threatened by the impacts of long-term contaminant releases from a number of industrial enterprises in its neighbourhood. Due to the complex hydrogeological settings and man-made impacts, effective protection of the Nova Ves groundwater resource requires careful co-ordination of mitigation measures at individual sites. It was proved that long-term pumping intensity (140 l/s) does not guarantee protection of the water quality. A reduction in the pumped discharge to 120 l/s was recommended. To ensure the long-term water quality in the water withdrawal area without any restriction on pumping discharge, a reduction in ammonium in the vadose zone by the 50 % would be required. However, so far, no remediation activities have been started.

Partially disarticulated new Miocene burrower bug (Hemiptera: Heteroptera: Cydnidae) from Cerová (Slovakia) documents occasional preservation of terrestrial arthropods in deep-marine sediments

The state of preservation of the bug Sehirus carpathiensis J.A. Lis, Vrsanský & Schlogl, sp. n. (Hemiptera: Heteroptera: Cydnidae) from the Laksarska Nova Ves Formation at Cerova (Slovakia) supports extremely rapid sinking and burial in upper bathyal Early Miocene sediments. The specimen originated from land at most a few kilometers away, but transport via a river can be excluded as the head and wings are still attached. Its most likely source based on fossil flora and the habitat of several living representatives of the genus is a riparian habitat in an adjacent area of land. Phylogenetically the new species is closely related to both Oligocene and living representatives of the genus, thus indicating an early Paleogene origin of the genus (like many other living insect genera). The observations based on two samples from one area (Czech Republic) indicate that terrestrial insects are occasionally preserved in deep marine environments, but overlooked due to their usually fragmentary and obscure nature of the preservation. The newly developed KVANT full-profile confocal measurement revealed a sample roughness Ra = 1.3-2.0 µm and abdomen submerged in the matrix 300 µm deeper than the more rigid pronotum.

Darrellhenryite, Na(LiAl2)Al6(BO3)3Si6O18(OH)3O, a new mineral from the tourmaline supergroup

Darrellhenryite, Na(LiAl2)Al6(BO3)3Si6O18(OH)3O, a new member of the tourmaline supergroup (related to the alkali-subgroup 4), is a new Li-bearing tourmaline species, which is closely related to elbaite through the substitution Y Al W 0.5O1 Y Li W –0.5(OH)–1. It occurs in a complex (Li-bearing) petalite-subtype pegmatite with common lepidolite, Li-bearing tourmalines, and amblygonite at Nova Ves near Ceský Krumlov, southern Bohemia, Moldanubian Zone, Czech Republic. This zoned pegmatite dike cross-cuts a serpentinite body enclosed in leucocratic granulites. Pink darrellhenryite forms columnar crystals (sometimes in parallel arrangement) up to 3 cm long and up 2 cm thick, associated with albite (var. cleavelandite), minor quartz, K-feldspar, petalite, rare polylithionite, and locally rare pollucite. The optical properties and the single-crystal structure study (R1 = 0.019) of darrellhenryite are consistent with trigonal symmetry, w = 1.636(2), e = 1.619(2), birefringence: 0.017, space group R3m, a = 15.809(2), c = 7.089(1) A, V = 1534.4(4) A 3 , and Z = 3. The chemical analysis, in combination with the results from the single-crystal structure refinement, gives the formula X (Na0.58Ca0.01o0.41)1.00 Y (Li1.05Al1.95)3.00 Z Al6 (BO3)3 T (Si6O18) V (OH)3 W (O0.66F0.34)1.00, which can be simplified to an ideal formula of Na(LiAl2)

Compositional and textural evolution of pollucite in pegmatites of the moldanubicum

Pollucite is found in five pegmatites in the Moldanubicum, all of them within the Czech Republic: Susice III (elbaite subtype) and Nova Ves near Ceský Krumlov (petalite subtype) in southern Bohemia, Jeclov I and Puklice II (lepidolite subtypes) and Věžna I (beryl-columbite subtype) in western Moravia. Pollucite displays a broad range of primary compositions at these localities, with CRK = 100(Cs + Rb + K)/Σ cations variable from 72 to 85, and Si/Al from 2.43 to 2.60. Exsolution to Cs,Al-rich and Na,Si-rich components is not widespread: the maximum CRK is 92 at Si/Al of 2.30. However, Na-exchanged compositions and local veinlets of analcime are much more common; they reach CRK of 5 and 7, respectively. Three occurrences are comparable to the usual pollucite-bearing assemblages, except for the geochemically rather primitive pegmatites at Susice and Věžna. At the latter locality, an extremely steep fractionation gradient generates minor amounts of a highly evolved Li-,Cs-,Be-, Ca-,Sr-,Ba-,Mn-,Bi-, REE-,Zr-,Sn-,Th-,W-,B-,P-,F-rich assemblage, with pollucite closely associated with chabazite and harmotome.
