Shallow seismic survey was made along 1280 m profile in the marginal zone of the Carpathian Foredeep. Measurements performed with standalone wireless stations and especially designed accelerated weight drop system resulted in high fold (up to 60), long offset seismic data. The acquisition has been designed to gather both high-resolution reflection and wide-angle refraction data at long offsets. Seismic processing has been realised separately in two paths with focus on the shallow and deep structures. Data processing for the shallow part combines the travel time tomography and the wide angle reflection imaging. This difficult analysis shows that a careful manual front mute combined with correct statics leads to detailed recognition of structures between 30 and 200 m. For those depths, we recognised several SW dipping tectonic displacements and a main fault zone that probably is the main fault limiting the Roztocze Hills area, and at the same time constitutes the border of the Carpathian Forebulge. The deep interpretation clearly shows a NE dipping evaporate layer at a depth of about 500-700 m. We also show limitations of our survey that leads to unclear recognition of the first 30 m, concluding with the need of joint interpretation with other geophysical methods.

The methodological experience and the results of observation and research have been presented as a part of an expert geological and engineering study for the planned extension of the Henryk Arctowski Polar Station on the coast of King George Island in the South Shetland Islands in Antarctica. The object is realized in an area requiring recognition of specific geodynamic conditions. According to technical requirements coming from the conceptual design project of the station (Kurylowicz and Associates, 2015) it was necessary to adopt a non-standard research program. Engineering and geological characteristics are presented in comparison with geoenvironmental considerations. The assessment of soil and rock properties was carried out in relation to the results of observations and determinations of parameters that could be assessed in the coarse-grained soils and rocks in the area of the designed object.

The research was carried out during Antarctic summer 2015/2016 in the region of Arctowski Polish Polar Station on King George Island (Southern Shetlands) in Admiralty Bay in Antarctica. The scope of hydrochemical studies included selected elements: temperature, pH, dry residue, general slurry, ammonium ion, nitrates, macroelements (chlorides, sulphates, magnesium, bicarbonates and carbonates, sodium, magnesium and calcium) and some microelements. Surface water and groundwater are low mineralized and do not show anthropogenic impact. The results ofphysicochemical tests have been compared with marine water chemistry and few available archival data, which allowed the assessment of water quality and the attempt to identify the groundwater flow direction.

Two multi-scan techniques: cyclic voltammetry (CV) and fast Fourier transform squarewave voltammetry (FFT SWV) with Pt and Au microelectrodes were tested for the determination of five carbohydrates (lactose, sucrose, glucose, fructose and ribose) under FIA conditions. The best analytical results were obtained for the FFT SWV with a Pt microelectrode; in this case the detection limits were below 2X10-7 mol . dm-3 for all studied analytes. In addition, both methods were applied for end-capillary detection in capillary electrophoresis (CE) and tested during an analysis of a mixture of eight sugars. The advantages of scanning methods over constant potential (amperometric) detection methods are also discussed.

In the article entitled Experience and module in shaping buildings in the Warsaw suburban zone it raised the issue of specific conditions which shaped the conception of city planning foundations in Warsaw. The author stresses that the medieval arrangement of the city did not differ from commonly accepted modules and that such a state lasted and included the 16th century. Only in the next centuries namely in the 1 7th and 18th century did the situation change. The old Warsaw situated behind medieval walls lost its significance and prestige. Relocation of the capital to Warsaw created a new situation for development (mostly town-planning) of the city, exactly, together with the King's residence, splendid residences of nobility, magnates, churches and monasteries began to be built. Demand for new building areas increased and as there were no spare plots within the limits of medieval Warsaw, buildings started to be erected in the suburbs. In the 19th century forts engirdling the city with a double ring were a barrier to the natural development of a suburban zone. The growing number of Warsaw inhabitants and also fast developing industry exacted densification of the buildings inside the fortification. The result of it was town-planning chaos and lack of proportion between city and suburban zone After regaining independence attempts were made to repair the town-planning setting of the city and improvement of its appearance. The short period of relative political stabilization of the interwar era brought many interesting town-planning solutions which the author discusses in her article in more detail.

A new detection technique called the fast F9urier transform square-wave voltammetry (FFT SWV) is based on measurements of ultramicroelectrode admittance as a function of potential. The response time of the detector (ultramicroelectrode) is less than 1 s, which makes the method suitable for most applications involving flowing electrolytes. The response is generated by a variety of processes involving the analyte, such as: reduction or oxidation, adsorption or desorption, surface transformation, inhibition of oxygen or hydrogen adsorption and changes in the solution resistance. Proper electrochemical conditioning of the ultramicroelectrode made of a noble metal (e.g. Au or Pt) provides a stable response for several hours. The new detection technique was tested under capillary elec-trophoresis and flow-injection conditions for the determination of ten phenothiazine derivatives. The detection limit was 2-5 * 10-7 mol 1-1 in CE and about 1 x 10-8 mol 1-1 in flow injection detections.

Nowa technika detekcji wykorzystująca woltamperometrię fali prostokątnej z szybką transformacją Fouriera (FFT SWV) jest podstawą pomiarów admitancji ultramikro-elektrod w funkcji potencjału. Czas odpowiedzi detektora (ultramikroelektroda) poniżej l s umożliwia zastosowanie tej techniki w układach przepływowych. Odpowiedź dętektora może być wywołana przez różne procesy takie jak utlenienie lub redukcja analitu, jego adsorpcję lub desorpcję, procesy przekształceń powierzchniowych, inhibitowanie adsorpcji tlenu lub wodoru a także zmiany rezystancji roztworu. Odpowiednie elektrochemiczne kondycjonowanie ultramikroelektrod z metali szlachetnych (Au lub Pr) prowadzi do otrzymania stabilnej odpowiedzi przez wiele godzin. Ta nowa technika została przetestowana w warunkach elektroforezy kapilarnej i wstrzykowej analizy przepływowej przy oznaczaniu dziesięciu pochodnych fenotiazyny. Limit detekcji dla tych związków wynosi 2-5 x 10(-7) mol 1(-1) w warunkach elektroforezy kapilarnej i około 1 x 10(-8) mol 1(-1) podczas oznaczeń w warunkach wstrzykowej analizy przepływowej.
