Opis:
The driven damped nonlinear Schrödinger equation is solved numerically and different attractors - periodic and chaotic ones - are obtained for different ranges of the forcing field amplitude. It is shown that these attractors are in both cases spatially nonuniform in time. Spatial inhomogeneity of the chaotic attractor is investigated by the estimation of the correlation dimension at different space points.

Opis:
The transition to phase and amplitude turbulent states in the one-dimensional complex Ginzburg-Landau equation is investigated by a numerical simulation. In order to describe existing attractors quantitatively, the largest Lyapunov exponent is estimated. The largest Lyapunov exponent is positive but small for the phase turbulence and it is much larger for the amplitude turbulence. Moreover, it seems independent on the system size.

Opis:
Three spatially extended one-dimensional dynamical systems are examined by numerical simulations and the time-delay technique is applied to find their dynamics at different positions in space. On the basis of this technique the correlation dimension is calculated from time series obtained at different positions. It is found that the value of the correlation dimension may vary from one position to another, reflecting the spatial inhomogeneity of the system.

Opis:
The paper presents the results of 57 Drill Stem Tests (DST) within the Upper Jurassic carbonate rocks forming the Carpathian Fordeep basement in the area between Bochnia and Ropczyce (south Poland) performed by the Polish Oil and Gas Company in the years 1993 to 1998. Designated prospective horizons were tested with DST for assessing productivity of strata. DST tests were performed mostly in open hole sections of boreholes (more rarely in cased holes) after prior borehole casing perforation operations. In approximately 75% cases the cycle drill stem tests (DST) was used for testing the Upper Jurassic carbonate rocks. On the basis of data and experiences obtained during exploration of the Upper Jurassic carbonate rocks the model of the work-flow decision diagram was elaborated. It may be used for the integrated HC field management and for possible modifications in the drilling and testing technology.

Opis:
The result and interpretation of reservoir tests (DST) are presented in the paper. They were performed in 20 intervals of 17 production wells in years 1995-1997. These wells are located in the Central Carpathians (flysch sand beds) and mainly in the external and internal Carpathian Foredeep (the autochthonous and allochthonous Miocene thin bedded sandstones) and their substratum (mainly carbonates). The basies of the theoretical diagnoses for determining the main types of drainage zones or limits of hydrocarbon accumulations are presented in the form of a short description of the Kappa Company's programmatic procedure (Saphir 202B system). Some diagnostic diagrams for the main reservoir border models are described using the log-log method. Examples of their geological interpretation are also provided.

Opis:
In the south part of the Carpathian Foredeep basement, between Bochnia and Ropczyce, the Upper Jurassic (Oxfordian, Kimmeridian and Tithonian) carbonate complex plays important role as a hydrocarbon bearing formation. It consists of shallow marine carbonates deposited in environments of the outer carbonate ramp as reef limestones (dolomites), microbial - sponge or coral biostromes and marly or micrite limestones as well. The inner pore space system of these rocks was affected by different diagenetic processes as calcite cementation, dissolution, dolomitization and most probably by tectonic fracturing as well. These phenomena have modified pore space systems within limestone / dolomite series forming more or less developed reservoir zones (horizons). According to the interpretation of DST results (analysis of pressure build up curves by log - log method) for 11 intervals (marked out previously by well logging due to porosity increase readings) within the Upper Jurassic formation 3 types of pore/fracture space systems were distinguished: - type I - fracture - vuggy porosity system in which fractures connecting voids and vugs within organogenic carbonates are of great importance for medium flow; - type II - vuggy - fracture porosity system where a pore space consists of weak connected voids and intergranular/intercrystalline pores with minor influence of fractures; - type III - cavern porosity system in which a secondary porosity is developed due to dolomitization and cement/grain dissolution processes.
W pracy scharakteryzowano metodykę interpretacji testów odbudowy ciśnienia z użyciem krzywych diagnostycznych i specjalistycznych oraz przedstawiono wyniki interpretacji testów złożowych rurowymi próbnikami złoża (RPZ) wykonanych w latach 1995-1997 w 11 profilach serii węglanowych górnej jury (malmu) budujących podłoże zapadliska przedkarpackiego w strefie Bochnia - Ropczyce. Uzyskane wyniki oraz szczegółowa interpretacja krzywych odbudowy ciśnienia dennego w powiązaniu z rozpoznanym rozwojem litofacjalnym utworów górnej jury pozwoliła wstępnie wydzielić charakterystyczne typy wykształcenia przestrzeni porowej, występujące w obrębie interwałów wytypowanych badaniami geofizyki wiertniczej do testów RPZ. Są to: I - typ szczelinowato-porowy z dominującym wpływem systemu szczelin; II - typ porowo-szczelinowaty z minimalnym wpływem szczelin oraz typ III - kawernisty, w którym system wolnych przestrzeni tworzą mikrokawerny, pustki i przestrzenie międzykrystaliczne powstałe głównie wskutek epigenetycznych procesów dolomityzacji i rozpuszczania. Wydzielone systemy można wiązać z facjami skał węglanowych, głównie organogenicznych, występujących w obrębie utworów górnej jury podłoża zapadliska przedkarpackiego.

Opis:
The aim of this experimental study was to analyse the influence of lumbar stabilisation used in the treatment of spondylolisthesis on the biomechanical properties of the human lumbar spine. FEM models were built on the basis of pre-surgical CT scans, routinely used in medical practice. MIMICS software was used to process the results of the neuroimaging study and to create 3D models. Two models were built: with and without a stabiliser. A static load analysis was performed for a normal upper-body load. The simulations allowed to determine the stresses in the individual discs for both models, with and without the transpedicular stabiliser.

Opis:
Recent demand for powering small sensors for wireless health monitoring triggered activities in the field of small size efficient energy harvesting devices. We examine energy harvesting in an aluminium beam with a piezoceramic patch subjected to kinematic harmonic excitation and impacts. Due to a mechanical stopper applied, inducing a hardening effect in the spring characteristic of the beam resonator, we observed a broader frequency range for the fairly large power output. Impact nonlinearities caused sensitivity to initial conditions and appearance of multiple solutions. The occurrence of resonant solution associated with impacts increased efficiency of the energy harvesting process.

Opis:
Introduction and objectives: In the United States, breast cancer (BC) is the most common non-skin cancer. In Poland, it is estimated that the number of new breast cancer cases affects about 13,500 women each year. There are many methods for nutritional status assessment. One of them is bioimpedance analysis (BIA). Direct bioimpedance measures (resistance, reactance, phase angle (PA)) determined by bioelectrical impedance analysis (BIA) detectf changes in tissue electrical properties. The study was conducted to investigate whether there are any tissue electrical differences in patients with breast cancer. Materials and methods: The direct bioimpedance measures determined by bioelectrical impedance analysis (BIA) were performed on 34 patients with BC and 34 healthy volunteers. The measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinkenba Qld 4008, Australia). Results: Reactance and resistance at 50 kHz was found to be significantly greater in patients with BC than in the control group (53.59° ± 1.53 vs. 47.26° ± 1.25, respectively, p=0.0031; 603.24° ± 15.38 ohm vs. 515.87° ± 11.48 ohm, respectively, p=0.00004). Conclusion: Pre-surgical patients diagnosed with BC have altered tissue electrical properties. Further observations of a larger patient group would be valuable to calculate survival, validate the prognostic significance of PA, and monitor nutritional and therapeutic interventions in this patient population.

An electron-beam generated plasma (EBGP) ion source for nuclear spectroscopy purposes at YASNAPP (YAdernaya Spektroskopya NA Putchkah Protonov - nuclear spectroscopy using proton beams) isotope separation on-line facility is presented. Working conditions both in on- and off-line mode are presented and discussed. Formation of a potential trap inside a discharge chamber is an advantage of the presented construction, enabling relatively high ionization efficiencies (2-5%) even for hard-to-ionize elements like Be, Ti, V, Zr, Nb, Mo, Tc, Ru, Rd, Hf, Ta, W, Re, Os, Ir, Pt. The paper presents estimation of critical values of working parameters that enable formation of the ion trap leading in consequence to high efficiency of ionization. The optimal temperature of the discharge chamber and cathode walls is found to be in the range 2600-2800 K. Calculations of the output rates of ions produced in the on-line mode are also presented as well as the constraints on the half-life time of obtained nuclides imposed by construction details like the target material and its thickness.
