Opis:
The Polish Geological Institute was established in 1919 as the national geological survey within the Ministry of Industry and Trade. The initiative of a group of parliament members to appoint the Polish Geological Institute was supported by the Polish Parliament on May 30, 1919, and the official opening of the Institute took place on May 7, 1919. Two years later the PGI status and budget were accepted by the Polish government and Józef Morozewicz has received director’s nomination from the Head of State Józef Piłsudski. In March 1938, the President of Poland accepted a new decree concerning geological survey of Poland which was composed of the Polish Geological Institute and the State Geological Council. The role of the PGI grew and the budget substantially increased, but this positive trend was stopped due to the beginning of World War II. During the first post-war years, regional and basic studies made it possible to establish a geological model of Poland leading to great discoveries of mineral deposits in the fifties. The decree of October 8, 1951 adjusted the organization forms of the geological survey to the system of central planning and the domination of state property, and the institute (with the name changed to the Geological Institute) became a scientific institution. During the first years the institute experienced good conditions of development, and a great progress in the knowledge of geology of Poland combined with the basic and regional studies that led to significant discoveries and documentation of mineral deposits. However, already in the seventies the first signs of crisis in geology became evident. In 1985, the Ministry of Environmental Protection and Mineral Resources was established, the Central Board of Geology was disbanded, and many tasks of geological survey returned to the institute, hence this turned out to be appropriate to return to the historical name, Polish Geological Institute, which took place on June 19, 1987. Since January 1, 2012, the Polish Geological Institute has served as the Polish geological survey on the basis of the Act of June 9, 2011, and earlier, since January 1, 2002, legally specified tasks of the Polish geological survey has been assigned to the PGI. On February 24, 2009 the Council of Ministers gave the PGI a status of National Research Institute, and this implied the adding this new status to the name of the Polish Geological Institute. For the century the Polish Geological Institute has successfully fulfilled all the basic responsibilities and commitments that are conventionally assigned to national geological surveys, and is a model example of modern national geological survey of very wide expertise.

Opis:
Established a few months after regaining independence in 1918, the Polish Geological Institute was carrying out research aimed at ensuring the supply of necessary mineral raw resources to the domestic industry. The director of the Institute, Prof. J. Morozewicz as well as the state authorities were aware of the fact that for the proper functioning of the Institute suitable headquarter was needed. Therefore, already in the mid-1919, the appropriate area and financial resources were allocated for the construction of large buildings, the designer of which S W0łk0wicZ T M Pervt was Prof. M. Lalewicz. The laboratory pavilion was opened in 1926. The main building, which was put into use in 1936 and rebuilt after the destruction during World War II, has been the pride of the Institute until today. The extension of the state and a wide range of research issues meant that already in 1921, it was necessary to establish the Upper Silesian Station in Dąbrowa Górnicza, whose activity was focused on the coal geology. The Geological Station in Borysław, operating in the structure of the PGI since 1920, was transformed three years later into the Oil and Salt Department of the PGI, which closely co-operated with the Carpathian oil industry. The Holy Cross Mountain research group was located during 1937-1955 in the family home of Jan Czarnocki. After World War II, due to the significant intensification of geological research and exploration in Poland, new regional divisions of the Institute were established that currently have their headquarters in Kraków, Sosnowiec, Wrocław, Kielce, Gdańsk and Szczecin; all have the rank of branches. The organizational structure of the PGI is of an extremely regional nature, and the research issues of individual branches are mostly related to the recognition of the geological structure and mineral resources occurring in a given region. In addition, the Polish Geological Institute possesses 8 core repositories.

Opis:
The paper presents the critical opinion expressed by Osiejewicz (2018b) who supports the view of Legislative Council of26 January 2018 on the draft act on the Polish Geological Agency that the German federal geological survey (Bundesanstalt fur Geowissenschaften und Rohstoffe - BGR) can be considered as an appropriate formula for the Polish Geological Institute - National Research Institute (PGI - NRI). This opinion is groundless and ignores the fact that because of the federal nature of FRG, many tasks of the national geological survey can, and are, accomplished by the state geological surveys only, and cannot be realized by BGR. PGI-NRI in turn accomplishes tasks of both BGR and the state geological surveys and in addition, possesses bigger potential to undertake new tasks.

Opis:
The Hanover declaration (1993) of the mission of a geological survey clearly states that it does not deal with management, but as a government organization it should serve the state authorities and societies by scientific advice and information on natural resources and the environment, and such a mission can be accomplished only by science, methodological competence and research independence. More than a half of the geological surveys in EU countries define themselves as research institutions (Fig. 1), and the scientific production expressed in the ratio ofpublications in JCR journals per staff number in some geological surveys (e.g. ČGS, BGS) is bigger than in the Polish Geological Institute-NRI (Fig. 2) what in part is related to the role played by sendee tasks of the PGI-NRI. The close connections of geological surveys with the scientific research are ignored by adherents of establishment of the Polish Geological Agency.

Opis:
Most western geological surveys, and in particular European Union countries and the USA, focus on public-good science for government, and research to understand earth and environmental processes, in order to supply neutral and independent advice and information about all geoscientific and natural resources issues to the government and society. In contrast, the current draft law on the Polish Geological Agency aims at introducing coherent hydrogeology and geology management as well as implementation of state policy in the field of resources security. Thus, the conclusion that the Polish Geological Agency is an analog of geological surveys, existing in many other developed countries, is absolutely unjustified.

Opis:
The Badenian section of Anadoly near Kamyanets Podilskyy (Ukrainian Carpathian Foredeep Basin) consists of the Tyras Fm. (gypsum and Ratyn Limestone) and the Ternopil Mb. of the Kosiv Fm. The latter are 5.3 m thick and are composed of dark grey mudstones with limestone intercalations. This study indicates the occurrence of over 54 species of benthic foraminifers and 10 species of planktonics. Benthic foraminifera are represented mainly by calcareous forms; agglutinated tests are very rare. Planktonic foraminifera appear in the upper part of the succession studied. Five benthic foraminiferal assemblages are recognized: A (Elphidium/Lobatula/Astrononion) B (Hauerinidae), C (Cibicidoides/Lobatula), D (Porosononion) and E (Uvigerina/Bulimina). The foraminiferal record indicates deposition in a shallow subtidal environment (20 m depth) of normal marine salinity and temperate waters followed by gradual deepening of the basin to >50 m. Analysis of foraminiferal assemblages indicates that bottom waters were highly oxygenated during deposition of the lower and middle parts of the Anadoly sequence. During deposition of the upper part of the sequence the oxygenation of bottom water gradually decreased, as expressed by a large decrease in the proportion of oxic species and an increase in dysoxic ones. The same set of samples yielded low amounts of palynological organic matter represented by dominant black opaque phytoclasts; bisaccate pollen grains and dinoflagellate cysts are rare. Taxonomically impoverished assemblages of the latter consist of dominant Polysphaeridium and Cleistosphaeridium placacanthum associated with Lingulodinium machaerophorum and a few other taxa. The taxonomically richest assemblage was found in the topmost sample. These changes were interpreted as indicative for increased salinity in the surface water layer, with its maximum in the middle part of the section; the assemblage from the topmost part is characteristic for normal marine salinity.

Opis:
The Zechstein Limestone of the Bonikowo 2 borehole is composed of limestone with varied dolomite content and is slightly thicker (3.4 m) than other supposed condensed sections in SW Poland. The microfacies (mostly bioclastic wackestones-packstones) are characteristic of open marine limestone deposited in deep shelf environments. The common occurrence of echinoids in all parts of the section, except close to its top, indicates no essential change in sea water salinity. However, the palaeotemperature interpretation of the highest δ18O value of calcite recorded in the Bonikowo 2 borehole (+0.32‰) indicates a temperature of 22.9°C when a δ18O of water = 2‰ is assumed. The δ13C and δ18O curves for calcite and dolomite are similar in shape, and their mean values are similar: +1.8 ±1.5‰ for calcite, respectively, and +1.9 ±2.3‰ and –4.3 ±2.4‰, –3.8 ±4.3‰ for dolomite. There is a recrystallized interval in the lower part of the section with both δ13C and δ18O values reduced. This may be regarded as an aerobic equivalent of the Kupferschiefer. The diversity and abundance of foraminifers is significant throughout the section studied; lagenids prevail, and this is considered to be due to the dysaerobic conditions throughout the duration of deposition of the Zechstein Limestone.

Opis:
The Jabłonna Reef, one of the reefs formed in Wuchiapingian time in the western part of the Wolsztyn palaeo-High (SW Poland), is characterized by quite irregular outlines and consists of three separate reef bodies (ca. 0.5–1.5 km2 each; the thickness of the reef complex is usually >60 m). It is penetrated by four boreholes, which show two distinct phases of bryozoan reef development during deposition of the the Zechstein Limestone. The first one occurred early in the depositional history and botryoidal aragonitic cementation played a very important role in reef formation. This phase of bryozoan reef development terminated suddenly; one possible reason was that a relative change of sea level – first a fall and then a rise – disturbed the upwelling circulation. Consequently, bioclastic deposition predominated for a relatively long time until the second phase of bryozoan reef development occurred, but the latter was not accompanied by dubious early cementation. During this second phase, reticular fenestellid bryozoans were predominant. Subsequently, microbial reefs developed and abound in the upper part of the Zechstein Limestone sections. The general shallowing-upward nature of deposition in the Jab³onna Reef area resulted in reef-flat conditions with ubiquitous, microbial deposits, in the central part of the Jab³onna Reef. Then, the reef-flat started to prograde and eventually the entire Jab³onna Reef area became the site of very shallow, subaqueous deposition. Five biofacies are distinguished in the Jab³onna Reef sections: the Acanthocladia biofacies at the base, then mollusc-crinoid, brachiopod-bryozoan, Rectifenestella and at the top, stromatolite biofacies. They represent a shallowing-upward cycle, possibly with some important fluctuation recorded as the distinctive lithofacies boundary, corresponding to the Acanthocladia/mollusc-crinoid biofacies boundary. The 13C curves of the Jab³onna 2 and Jab³onna 4 boreholes permit correlation of the trends in the middle parts of both sections and confirm the strong diachroneity of the biofacies boundaries, with the exception of the roughly isochronous Acanthocladia/ mollusc-crinoid biofacies boundary. The presence of echinoderms and strophomenid brachiopods indicates that until deposition of the lower part of the Rectifenestella biofacies, conditions were clearly stenohaline. The subsequent elimination of stenohaline organisms and progressively poorer taxonomic differentiation of the faunal assemblage are characteristic for a slight, gradual rise in salinity. The taxonomic composition of organisms forming the Jab³onna Reef shows a similarity to reefs described from England and Germany, as well as the marginal carbonate platform of SW Poland. Filled fissures were recorded in the lower part of the Jabłonna Reef. The aragonite cementation recorded in some fissure fillings implies that they originated in rocks exposed on the sea floor and are neptunian dykes.

The paper presents a part of a prototype system for the monitoring of selected vital functions of humans and some preliminary results obtained from the device using implemented algorithm. The system consists of such essential modules like a microcontroller board, an inertial measurement unit and additional sensors. The main task of the device is human movement monitoring and detecting selected anomalies, e.g. fall or fainting. At the first stage, the movement classification was considered. The main movement type are walking, running and selected variants of transitions between different phases like standing up or going downstairs. The determining of the movement is based on the intuitive algorithm using raw data from accelerometers complemented by sensors like barometer and heart rate monitor. The algorithm utilizes automated multiscale-based peak detection and wavelet transform energy calculations. Finally, some further work directions and development possibilities are discussed.

In this paper, the authors present selected examples of rapid prototyping environment consisting of a popular hardware platform like Arduino and software tools, like graphical language LabView. As a case study the MEMS (Micro Electro-Mechanical Systems) applications are described. First, the initial requirements regarding software and hardware are introduced. Next, some basic configuration procedures are presented. The main application example is a MEMS sensor data acquisition system. It shows the possibility of using LabView and non-dedicated hardware with a large number of Arduino compatible modules. The communication between Arduino and LabView is realized by a serial wire connection. Further examples show wireless communication with Arduino using Bluetooth link. The presented applications are very common in the embedded system environment and their implementation can be done with minimal effort on creating software code.

Skład i zmiany zespołów otwornic pochodzących z najwyższej części utworów podewaporatowych w otworze wiertniczym Busko (Młyny) PIG-1 (głęb. 188–192 m), zlokalizowanym w północnej części zbiornika przedkarpackiego (Paratetyda Środkowa), wskazują, że zbiornik, w którym powstawały osady margliste, był słabo wentylowany, z dużym deficytem tlenowym w wodach przydennych oraz ze środowiskiem eutroficznym w wodach powierzchniowych. Zbiornik ten, o głębokości 50–70 m, wypełniały wody chłodne o zasoleniu typowym dla zbiornika morskiego. Obserwowane w najwyższej części profilu prawie całkowite wyeliminowanie otwornic Uvigerina i zajęcie na krótko zwolnionej niszy przez Fursenkoina acuta (zespół D4c) oraz zdominowanie składu najmłodszego zespołu (D4d) przez tolerującą podwyższone zasolenie Bulimina elongata może jednak wskazywać na znaczne podwyższenie zasolenia w trakcie depozycji najwyższej części utworów poprzedzających depozycję gipsów. Profil gipsów badeńskich w badanym otworze wiertniczym w porównaniu z bardziej brzeżną strefą platformy gipsowej cechuje się redukcją dolnej, autochtonicznej części gipsów oraz specyficznym wykształceniem najniższej jednostki gipsów. W matriksie ilastym występują tam gruzły gipsu bardzo przypominające małe, chaotycznie ułożone blokowe zrosty krystaliczne, określane jako facja szkieletowa gipsów szklicowych, związana w niecce Nidy oraz na Morawach z obniżeniami dna. Wykształcenie profilu gipsów wskazuje na głębsze środowisko sedymentacji niż to stwierdzono w rejonie niecki Nidy.
Composition and changes in foraminiferal assemblages recorded in the uppermost part of the sub-evaporite deposits of the Busko (Młyny) PIG-1 borehole (depth 188–192 m) in the northernmost part of the Fore-Carpathian Basin (Central Paratethys) indicate that the basin, in which marly deposits have originated, was poorly ventilated with a great oxygen deficit in the bottom waters, and was characterised by mainly eutrophic conditions in surface waters. The basin was 50–70 m deep. The waters were cool and of normal seawater salinity, although the recorded (in the uppermost part of the section) almost complete disappearance of Uvigerina foraminifers, occupation (for a short time) of the vacant niche by Fursenkoina acuta (assemblage D4c), and the dominance of Bulimina elongata (tolerant to increased salinity) in the youngest assemblage (D4d) may indicate a considerable increase of seawater salinity during the deposition of the uppermost part of the sub-evaporite strata. The gypsum section is characterised, when compared to the more marginal gypsum sections of the Nida Trough, by a reduction of the lower, autochthonous part of the gypsum section and a specific development of the lowermost gypsum unit. It contains gypsum nodules resembling small, chaotically arranged gypsum intergrowths in the clayey matrix. Such facies is regarded as the skeletal facies of the giant gypsum intergrowth facies of the Nida Trough and Moravia, and is related to depositional lows at the beginning of the gypsum deposition. The gypsum sequence in this borehole indicates a deeper sedimentary environment than inferred for the Nida Trough.

Opis:
The development of basal Zechstein (Wuchiapingian) strata inSW Polandindicates the existence of a diversified relief inherited after the flooding of the pre-existing depression by the transgressing Zechstein sea. The deeper parts of the basin were the place of development of thin basinal Zechstein Limestone showing sedimentary condensation manifested by bored and encrusted grains and thick evaporites (mostly halite), and in shallow parts Zechstein Limestone reefs followed by thinner evaporite sequences (dominated by anhydrite) occur. The analysis of 3D seismic sections showed that instead of three conventionally recognized evaporite units of stratigraphic potential in the PZ1 cycle, five units occur (from the base to the top: Lower Anhydrite, Lower Oldest Halite, Middle Anhydrite, Upper Oldest Halite, Upper Anhydrite). In a particular place their number may vary from two (Lower Anhydrite at the base of the PZ1 cycle and Upper Anhydrite at the top of the PZ1 cycle) to five. There are two complexes of Lower Anhydrite occurring throughout the platform and basinal zones showing deepening-upward (transgressive) trend. The halite sedimentation in the deepest parts of salt basins began shortly after the deposition of the upper Lower Anhydrite complex while in the sulphate platform areas the sulphate deposition lasted still for a long time. The Lower Oldest Halite deposits occur in the depressions. Between the halite basins, anhydrite platforms occur, and the thickness of anhydrite platform deposits is smaller than it is observed in salt basins. The Upper Oldest Halite in turn is recorded above the anhydrite platform. The two halite units represent different phases of development of halite basins. The Lower Oldest Halite basins are related to the pre-Zechstein depressions, although in some cases their syndepositional subsidence was controlled by reactivation, during the deposition of basal Zechstein strata, of former faults. In turn, the Upper Oldest Halite basins used the accommodation space created due to anhydritization of the Lower Anhydrite deposits composed originally of selenitic gypsum. The 3D seismics evidences that the PZ1 evaporites inSW Polandhave been deposited in far more complex and dynamic system than it was assumed before.

Opis:
The Upper Badenian marly shales overlying gypsum and the Ratyn Limestone at Shchyrets, Ukraine, contain moderately to well-preserved benthic (calcareous only) and planktonic foraminifers, and palynofacies dominated by bisaccate pollen grains, presumably transported by wind. Both foraminiferal and dinoflagellate cyst assemblages indicate an open marine environment with normal-marine salinity and cool waters. The palaeodepth was ca. 50 m except for the uppermost part of the section studied, where a distinctive deepening is indicated by the dominance of Uvigerina in benthic foraminiferal assemblages and a high P/B ratio. The water was thermally stratified and the differences between the bottom water and the water column show an upwards-increasing trend. Bulimina and Globocassidulina are the most common and dominant component of benthic foraminiferal assemblages, except for the uppermost part where Uvigerina dominates the assemblage. The composition of benthic foraminifer assemblages and δ13C values of foraminifers indicate nutrient-rich waters and mesotrophic to eutrotrophic environments in surface waters, and low oxygenation at the sea floor in the Ukrainian Carpathian Foredeep Basin during the Late Badenian.

Opis:
Dolomitisation was the main diagenetic process in the Upper Permian Zechstein Limestone of the Wolsztyn High-dolomite cementation (“over-dolomitisation”) also occurred. The rocks studied usually have a mixed mineralogy and represent a continuous spectrum from pure limestone to pure dolomite. This is due to varying degrees of dolomitisation, dolomite cementation and dedolomitisation. There are two main types of dolomite: replacement dolomite (mostly planar unimodal dolosparite mosaics that are mainly fabric-destructive) and cement dolomite (planar isopachous rims and pore-filling non-planar saddle-dolomite crystals). The timing of dolomitisation and dolomite cementation is difficult to ascertain, but comparing petrographical and geochemical data indicates that the reef carbonates were dolomitised shortly after deposition in a near-surface sabkha/seepage-reflux and then in burial systems. It seems that many of the dolomites gain their present isotopic composition when buried in relatively high-temperature conditions, as shown by low oxygen isotopic ratios ( δ18O as low as –9‰ PDB) and the presence of saddle dolomite. No isotopic support for a water-mixing mechanism is documented.
