This paper presents the results of descriptive terminology management study which was conducted using the monolingual specialised corpus in Croatian language. Semasiologicaly oriented methodology was ...used in distributional analysis of terminological units and its co-occurrences. The lexicogrammar model Classes of objects was applied in order to create semantic groups according to the syntagmatic and paradigmatic profile of terminological units. Syntagmatic units were analysed emphasizing the adjectives that specify the meaning of the concept. Their function is described using the paraphrase model that highlights the specialised meaning of adjectives. Significant adjectives point towards the multidimensional classification of concepts which help represent the dynamic categorisation of concepts inside a specialized field such as karstology.
The scientific monograph ('Palaeofloods in karstic Ljubljanica River Catchment') presents a research on palaeofloods in the main water confluence in the Ljubljanica River Catchment, namely the area ...between the Pivka Basin, Cerknica Karst Polje, and Planina Karst Polje. Several geomorphological forms genetically related to floods have been identified, e.g. floodplains, river terraces, corrosion notches on cave walls, as well as laminated fine-grained sediments. Since they were found at higher altitudes than the present floods reach, they were considered as palaeoflood features. Morphometric analysis of the studied geomorphological forms was used to determine the volume of palaeofloods and their altitudinal range. The hydrometric characteristics of the palaeofloods where calculated by computer modelling. Petrological analyses of fine-grained sediments from the surface and caves were used to determine the origin of sediments and their settling velocities, hence to prove their flood origin. Furthermore, morpho-chronological analyses with radiometric methods 14C and U-Th on flowstones interlaying with flood sediments where carried out. The results show that the volume and altitude of palaeofloods throughout the study area fairly exceeded the highest known recent floods.
Monitoring of air temperature takes place at five locations in two cave systems. At monitoring location Velika gora (Postojna 1), mean air temperature for the time period 2009–2010 was 11.10 °C. Of ...three monitoring locations Velika gora is situated at the highest absolute height. Mean air temperature in the same period was 10.66 °C in the central part of the Lepe jame cave (Postojna 3) and 10.30 °C in the side passage (Postojna 2). Temperature difference between outside and cave temperature is the highest at Postojna 2 monitoring location, due to the inflow of the air currents from the unknown parts, especially in winter time. Manual temperature measurements (2004–2010) exhibit slight increase of air temperature at Postojna 1 and Postojna 2 monitoring sites. In the Predjama cave system, the air temperature in Velika dvorana is much more stable than in Konjski hlev passage, which is more subject to external influences.
The Jurassic limestone of the North-eastern part of the Aquitain Basin (Angoulême, Charente, France) provide evidence of the prominent role of the ghost-rock process from the study of three quarries, ...drillings and the discovering of a young cave called “La Fuie” (Chasseneuil-sur-Bonnieure). This alteration process explains the genesis of maze caves and also the complexity of the Touvre aquifer which supplies the city of Angoulême. Indeed the large water reserve is situated into the porous rock (slow drainage) constituted by ghost-rocks while a small part is drained by the karst conduits (fast drainage coming from river losses). Moreover, for the first time a speleogenesis by ghost-rock process is demonstrated in a young and active subterranean network in Charente. La Fuie Cave, discovered during road works, was used as subterranean laboratory. Analysis of ascending collapse chimney and the discovery of ghost-rock combined with the study of piezometric level variations, recorded by a Luirograph, allowed to highlight a new way to drain residual deposits by flooding / dewatering of pseudo-galleries from ghost-rocks in cave system. At the same time, the piezometric level variations in the epiphreatic zone are the cause of a partial filling of the galleries.

Academician Ivan Gams is Slovenia's best known researcher of karst and the most prolific author of works on karst. During his first job at the Institute of Geography of the Slovenian Academy of ...Sciences and Arts, he started researching the karst surface and underground. He published several in-depth publications on karst caves, the most well-known being the studies of the shaft Triglavsko brezno in the 1960's. Right from the beginning, he focused on issues to which he then dedicated more or less his whole life − and which were also widely recognized by professional public both at home and abroad −, namely corrosion intensity determined by the hardness of water and the discharges of karst rivers and springs, and the method of limestone tablets. Within the geomorphology of karst, Gams was mostly dealing with the karst polje, especially its definition and evolution.
Rock features are important traces of the formation and development of karst surface. On various karren their record is especially rich, revealing to us the many factors that in diverse conditions ...formed the karst surface on various carbonate and other rock.We have tried to present the most characteristic rock features and through them the most important factors and processes in the formation of the karst surface, the methods of studying them, and the most outstanding examples.Forty-nine contributing authors offer a wide spectrum of content and examples of rock forms from many karst regions around the world.The first part of the book offers an orderly-organized survey and description of the most characteristic rock forms and presents the physical and chemical corrosion of rock, biocorrosion, the modeling of rock forms, their detailed morphometrics, and numerous descriptions of individual rock forms. The second part is devoted to various examples of rock forms found around the world from Slovenia through North and South America to Australia and Asia.
