Human environment relations have always been present in research undertaken in the Department of Latin America, although they rarely played a dominant role in particular study projects. On everyday basis that presence was reflected in carefull application of correct regional geographical terrninology both in our writing and teaching. Environmental conditions were usually a necessary part of the characteristics of the study area, the basic background for understanding the different phenomena, one of the many factors shaping social and economic processes examined. Such a way of perceiving natural environment and human - environment relations has been also typical for many master's thesis prepared under the supervision of the Department's staff members, as well as for doctoral and habilitation dissertations of the Department's academics. In the latter human - environment relations on one hand were part of the characteristics of the surveyed regions and they were treated rather indirectly, for instance through the selection of case studies coming from areas of differing environmental conditions. However there are also two examples of studies concentrated on human- environment relations as the most important research problem. The first one concerned agriculture among ribereños peasants in the Peruvian Amazon and the second one: Alvarado y el Mundo del agua (Alvarado and the acuatic world) described social and economic behaviour of fishing communities in the Papaloapan River Delta and on the shores of Laguna de Alvarado, Mexico. Anothcr text on „Nature and her visions” is an attempt of recovery - on the basis of documents and other written sources, of the way in which explorers, conquerors, colonists, researchers and present-day people: - residents, visitors and tourists see Latin American nature. Human - environment related research conducted at the Department of Latin America was based on E.A. Ackerman 's understanding of geography expressed at the meeting of the Association of American Geographers in 1963: the leading research problem for geographers is the desire to understand the human – environment relations on the global scale.

W artykule omówiono i porównano wpływ sposobu preparowania próbek pomiarowych na przebieg i parametry kinetyki utleniania sadzy (PM). Z porównania wynika, że w przypadku sadzy osadzonej w kanalikach filtra proces jest wolniejszy i przebiega w niższych temperaturach niż w przypadku sadzy nałożonej na próbkę powierzchniowo. Ponadto stwierdzono, że wpływ sposobu preparowania próbek na wartości parametrów kinetyki jest nieznaczny. Oznacza to, że przyjęta w badaniach metoda preparacji próbek polegająca na powierzchniowym nakładaniu sadzy jest równoprawna.

The article contains review and analysis of the sample preparation procedure on the PM oxidation process and PM oxidation kinetics parameters. The comparative analysis had shown that in case of PM inserted in the sample ducts, oxidation process is slower and its maximal temperature is lower than in case of equivalent process conducted with samples with PM imposed on the surface. The analysis found that the effect of preparation of samples for the kinetic parameters is negligible. This means that adopted in the study sample preparation method involving the imposition of the PM on the sample surface is correct.

The specular reflectivities of picosecond and subnanosecond high-intensity light pulses from a gold target are investigated and compared. It is found that the reflectivity for a picosecond pulse is several times higher than for a subnanosecond one and that dependences of the reflectivity on light pulse energy or intensity are different for both kinds of pulses. A qualitative explanation of the observed features of reflectivity is provided.

The paper deals with the nonlinear theory of thin shell structures in the presence of irregularities in geometry, deformation, material properties and loading. The irregular shell is modelled by a reference network being a union of piecewise smooth surfaces and space curves, with various fields satisfying relaxed smoothness, differentiability, and regularity requirements. Transforming the virtual work principle postulated for the entire reference network, the corresponding local field equations and side conditions (boundary and jump conditions) are derived. It is shown that no more than four static and work-conjugate kinematic jump conditions can correctly be formulated whenever the shell deformation is assumed to be entirely determined by deformation of the reference network capable of resisting to stretching and bending. This assumption includes various specjal formulations of the Kirchhoff-Love type theory of elastic shells, as well as their substantial generalizations accounting for finite strains and inelastic deformations.

The results of experimental investigation of the interaction of picosecond light pulses with a Cu target at light intensities up to 3.10/sup 16/ W/cm/sup 2/ are presented and discussed. The experiment was performed with the use of a terawatt chirped-pulse-amplification Nd:glass laser and the apparatus for corpuscular (ion collectors, electrostatic ion energy analyser) and X-ray (p-i-n Si photodiode) diagnostics of laser-produced plasma. The charge spectra of ions emitted from a picosecond plasma as well as the energy-dependent (or intensity-dependent) characteristics of ion emission and soft X-ray yield are determined. The electron temperature and the average charge state of the plasma are evaluated as a function of light intensity.

The purpose of this paper is to present the newly-opened High Power Laser Laboratory (HPLL) at the Institute of Plasma Physics and Laser Microfusion (IPPLM). This article describes the laser, the main laboratory accessories and the diagnostic instruments. We also present preliminary results of the first experiment on ion and X-ray generation from laser-produced plasma that has been already performed at the HPLL.

The results of comparison of X-ray emission from plasmas produced by 1-ps and 0.5-ns laser pulses from massive and foil targets are reported. The measurements were performed for the soft (0.8-1.6 keV) and hard (4-30 keV) X-rays with the use of filtered p-i-n Si photodiodes at laser intensities of up to 10/sup 17/ W/cm/sup 2/ for ps pulses and up to 3 * 10/sup 14/ W/cm/sup 2/ for sub-ns ones. The effect of the laser pulse duration on the X-ray yields for various laser beam focal spots, laser pulse energies and atomic numbers of the targets were investigated.

The dependences of parameters of laser-produced ion fluxes on the laser focus position with respect to the target surface for picosecond laser pulses are presented and compared with the ones for sub-nanosecond pulses at nearly the same densities of laser energy. The experiments were performed with the use of chirped-pulse-amplification Nd:glass laser system. Thick Au targets were irradiated by normally incident laser pulses. The maximum intensities of the focused laser beams were 8 * 10/sup 16/ and 2 * 10/sup 14/ W/cm/sup 2/ for ps and sub-ns laser pulses, respectively. The particle fluxes were analysed with the use of ion collectors and an electrostatic ion-energy analyser. The ion current densities and the charges carried by ions as well as the maximum and peak velocities of fast and thermal ion groups as a function of the focus position for ps and sub-ns pulses were determined.
