Systemy Informacji Geograficznej (GIS) stają się coraz powszechniej stosowanym narzędziem w badaniach przestrzennych. Duże miasta były tymi gminami, które najwcześniej podjęły prace zmierzające do wdrożenia GIS na swoim terenie. W artykule przedstawiono stan tych prac w wielu miastach polskich (Łódź, Gdańsk, Poznań, Wrocław, konurbacja Górnego Śląska, Kraków).

The paper contains a broad review of efforts taken up in several large cities of Poland (Łódź, Gdańsk, Poznań, Wrocław, Kraków and Upper Silesia region) to create and implement GIS in the activity of local government, especially in the field of physical planning and land management on municipal level. So far, such application consist usually in capturing manualy drawn plans into computerized systems. There is, however, much prospect for the use of GIS in the process of plan making and decision support systems. There in also quite a large area of potential GIS applications in small and medium sized municipalities. However, for financial reasons, such applications will have to be simplified and will concern only a few selected aspects of land managament.

Self-assembled monolayers (SAMs) of 4-methyl-4'-mercaptoethyl-biphenyl (HS-CH₂-CH₂-C₆H₄-C₆H₄-CH₃) and nexadecane thiol (HS-(CH₂)₁₅-CH₃ adsorbed on Au(111)/mica were investigated by cyanide etching in order to identify defects in the monolayer. The etch pits formed around a defect were examined ex situ by scanning tunneling microscopy. For both tiols removal of gold atoms begins in the vicinity of terrace edges and leads to the formation of triangular pits on the gold terraces. The defect densities of both thiols are comparable and the etch rate slightly higher for the alkane thiol compared to the biphenyl thiol. This feature combined with a charge permeability orders of magnitude higher than for alkane thiols makes biphenyl based thiols a promising material for modifying electrochemical properties of electrodes.

STM/AFM and LFM microscopes were used for morphological analysis of uniform and patterned self-assembled monolayers (SAMs) formed from docosanethiol (HS-(CH₂)₁₁CH₃), dodecanethiol (HS-(CH₂)₁₁CH₃) and mercaptododecanoic acid (HS-(CH₂)₁₁COOH) molecules adsorbed at 200nm gold film deposited onto silicon wafer. All measurements were performed in air. The lateral distances between atoms were determined using HOPG sample for calibration. Images obtained on clen Au substrate revealed that the surface was not uniform but was composed from flat crystallites having {111} surfaces. For DCT/Au samples a (√3 x √3) R30° reconstruction of molecules was detected. In this case, electron tunneling was pesumed to occur between the microscope itp and gold-bound uslfur atom of DCT molecule. Depressions with a diameter of 40÷150 Å and a depth of approximately 2.4 Å were observed on otherwise flat surface of DCT monolayer. Our results support hypothesis that defects are formed by removal of Au atoms that takes place during monolayer formation when the substrate is immersed in ethanol solution.

Background: Fractures of the proximal epiphysis of the tibia constitute one of the more frequently occurring types of sports injuries, and at the moment constitute about 1% of all reported bone fractures. They appear mainly as a result of traffic accidents, falls from heights, as well as being observed in groups of physically active people whose disciplines involve high-impact landings. From time to time, improperly executed movements or steps without falling result in injury. Case Report: We present a case study of a 21-year-old male football player with fracture of the lateral tibia condyle with indentation of articular surface. The patient came to the clinic with increasing pain in the knee joint, resulting from torsional injury which occurred the same day. Conclusions: A quick and accurate diagnosis as well as treatment of fractures of the lateral tibia which includes surgery, rehabilitation and supportive orthobiology, minimize the risk of chronic symptoms of the injury such as limited range of motion and subsequent osteoarthritis.

Laser postionization technique has been used to invetigate processes that occur during ion bombardment of thin organic layers. Dependence of the kinetic nergy disrtibutions has been investigated as a function of layer thickness and projectile type. Thin films obtained from self-as-sembled monolayer of phenylethanethiol on gold and C₆H₆ on silver have been probed. Results indicate that the sputtering mechanism depends on the organic material used. Phenylethanethiol molecules are emitted predominantly with thermal kinetic energies and the shape of the distribution depends on surface temperature. Emission of benzene is much more energetic and possesses characteristics similar to sputtering of metals. Emission of phenylethanethiol molecules is stimulated by a chemical reaction, which gently breaks the adsorbate surface bonds. Benzene molecules are emitted from the thin overlayer due to collisions with ejecting substrate atoms.
