The importance of GIS detailed data for geomorphostructural study is discussed. This paper is a case study in the area of Inowrocław (central Poland). This small area is a place being a concentration of geological processes and its relief depicted by a number of height points (with determined elevations of satisfying accuracy required in the analysis) demonstrates their effects. The invented approach is based on a numerical analysis of actual and theoretical relief surfaces. Considering the area type this study involves a high resolution model of the relief. There are specified examples of correlation between morphological features and tectonic structures. The presented results prove a role of structural elements (faults) in development of geomorphostructural features and a tectonic mobility as a significant factor forming the area relief., Zbigniew Szczerbowski., and Obsahuje bibliografii
This paper describes a prototype of the authors own design used to measure the relative inclinations of engineering objects and inanimate nature phenomena. A set of measurements can be used to determine ground surface deformation caused by mining activities or due to influences of hydro-geological, geotechnical or construction. The instrument was built with elements of the optoelectronic technique. Fiber optic, CCD camera and semiconductor laser are the basic building blocks of the device. The elaborated device runs on a Central Registration and Data Processing (CRP D) System. The deflection of freely suspended fiber are recorded by a CCD camera and next are transmitted to an external recorder (eg. notebook). Natural light or laser light was introduced into the fiber. The length of the fiber and the optical construction affects the measuring range of the device. The accuracy of instruments depends on: method of fiber suspension, method of fiber attenuation fluctuations, resolution CCD camera and identification method of the image laser spot recorded. Experiments have shown that the built prototype device is able to obtain a submillimetre accuracy., Kazimierz Ćmielewski, Janusz Kuchmister, Piotr Gołuch and Krzysztof Kowalski., and Obsahuje bibliografické odkazy
The future of the global and local geodynamic researches belongs to permanent monitoring. The conception of the semipermanent GPS observations’ application in geodynamic research in Sudetes area is presented in this paper. The conception is based on spatial modeling of the disturbing phenomena in the coordinate time series of (semi) permanent stations. The local interplate movements and their correlation with major European tectonic structures are determined on the strength of coordinate time series of these stations. The problem of epoch integration with semipermanent and permanent (EPN/IGS) observations for local geodynamic monitoring is also investigated., Bernard Kontny, Jarosław Bosy and Andrzej Borkowski., and Obsahuje bibliografii
During our studies on gastrointest-inal motility in suckling rats using 51Cr or 51Cr-EDTA as markers, we noticed that these markers - in contrast to studies in adult rats "adhered" to the gastrointestinal wall of sucklings. We therefore decided to test the use of another non-absorbable marker Poly R-478 (an acetylated anthrapyridone chromophore linked to an polyamino-ethylene-sodium ethylene sulfonate copolymer backbone developed by the Dynapol Corporation (Palo Alto, CA). This new method has appeared to be useful.
Aleurodicus dispersus Russell (Hemiptera: Aleyrodidae), a highly polyphagous species, has since the 90's been an important pest of ornamentals and tropical crops in the Canary Islands. In this study the RAPD-PCR technique was used to study the genetic structure of this whitefly in this archipelago. A total of 68 different bands were scored in seven populations using six primers for amplification. No differences in RAPD patterns were found among populations from different islands of the Canaries. These findings indicate a very high genetic similarity among populations and low level of genetic variability and support a single colonization event by few A. dispersus whiteflies and recent dispersion throughout the archipelago.
Rubber dam is considered an ideal device for tooth isolation. Nevertheless, its usage is quite rare in the Czech Republic. The aim of this study was: firstly, to gather and evaluate information regarding the use of rubber dam by dentists in the Czech Republic and to compare it with other countries; secondly to find out whether there are any influencing factors as to rubber dam usage; and finally to find out frequency of rubber dam use separately in endodontic treatment and in placing fillings of different materials. A questionnaire-based survey was conducted. Dentists filled in the questionnaires during dental conventions, educational events, conferences and congresses. Rubber dam was routinely used by less than eight per cent of the respondents (n = 35); less than twenty-two per cent of the respondents (n = 97) used rubber dam occasionally, and more than seventy per cent of the respondents (n = 317) has never use it. The results showed that rubber dam is not used frequently in the Czech Republic. If rubber dam is used, then it is typically for endodontic treatment or composite fillings. There were several factors with a statistically significant influence on the usage of rubber dam, such as gender, length of professional career, percentage of direct payments, previous experience in using rubber dam, and undergraduate training in rubber dam use., Martin Kapitán, Zdeňka Šustová, and Literatura 22
The article discusses techniques for interpreting satellite images, which are capable of detecting and monitoring landslip zones, and presents a research plan for the study of landslips with the use of satellite interferometry. The exceptionally longlasting and heavy rainfall that occurred in 1997 initiated more than 20,000 landslips within the Polish Carpathians. These landslips continue to pose a threat. Some of them move almost imperceptibly - slowly but continually - yet long-lasting periods of heavy rainfall can lead to catastrophe. The price can be human lives, as well as losses into the millions connected with the devastation of technical infrastructures and entire housing estates. The sheer number of landslips that occur in the Polish Carpathians makes the traditional ways of researching them insufficient. Satellite remote sensing allows capturing a large area of interest on a single photo. Many various satellites photograph the surface of the Earth using different techniques, allowing for the selection of the best-suited image type for a given application. Synthetic Aperture Radar (SAR) images are utilized in landslip studies. The images may be interpreted using the InSAR and/or PSInSAR techniques. Both methods are capable of detecting landslip zones and monitoring them in order to assess the risk of a sudden landslide. Information of this type is significant to local authorities when planning the activities necessary to protect the safety of inhabitants and the local technical infrastructure., Katarzyna Mirek., and Obsahuje bibliografii
Karyotypes of 16 Eupelminae species were analyzed. The haploid chromosome number was found to be much more diverse than the n = 5 previously recorded for three studied species. All species investigated of Eupelmus (Eupelmus), Eupelmus (Macroneura), Merostenus excavatus and three species of Anastatus have a karyotype of n = 5; n = 7 in Eupelmus (Episolindelia) linearis, n = 8 in Arachnophaga picardi, and n = 10 in Anastatus ruficaudus. The modal chromosome number is n = 5 and this is considered to be the plesiomorphic character state for the subfamily; karyotypes with higher chromosome numbers are hypothesized to be derived independently from the ancestral state by centric fission. This cytogenetical data provides important information on the subfamily systematics, especially the subgeneric classification of Eupelmus and generic placement of Eupelmus rostratus.
