Considerations regarding global environmental risk taxonomy and assessment
(2009) Băbut, Gabriel; Moraru, Roland Iosif; Cioca, Lucian-Ionel
Based on a critical analysis of literature, the paper has as goal to highlight the basic elements, which should be taken into account in assessing a coherent framework for assessment and classification of global environmental risks. In order gather the attention of professionals in this field of concern, a rather unemployed approach is used, based on the analogy with characters and situation specific to Greek mythology. In correlation with the above- mentioned issues, in the final section of the paper, an attempt is made to develop a management strategy of global environmental risks.
Zagadnienia ilościowej oceny poziomu wiedzy fachowej w górnictwie nafty i gazu
(2009) Bednarz, Stanisław; Rzyczniak, Mirosław
The considerations on test exams usability for knowledge effective examination and skills of large group of persons in short period are described in the article. Probability changes of test passing without knowledge required are specified in form of diagrams and tables including such parameters as: test questions number, answers variants number and required percent of correct answers assuming the same weight of all questions answered.
Badania wodoprzepuszczalności gruntów spoistych na podstawie metody Kaczyńskiego
(2009) Drożdżak, Ryszard; Twardowski, Kazimierz
Theoretical and practical assumptions of Kaczyński method for laboratory determination of filtration coefficient in compact ground described in the paper. Tests focused on determining technical-methodic conditions of measurements for establishing the influence of chemistry of the filtrating water on the obtained parameters. The physical model of compact ground as well as physicochemical properties of various concentrations of NaCl and CaCl2 water solutions used as working fluids were analyzed quantitative and qualitative. For comparison's sake, tests for demineralized water were made. The obtained results are promising as far as evaluation of the correction coefficient accounting for the influence of chemistry of water on water permeability of ground is concerned.
Analiza zagrożenia dla środowiska gruntowo-wodnego na podstawie danych z erupcji wstępnej
(2009) Dubiel, Stanisław
The way of determining reservoir pressure gradient and specific gravity of reservoir fluid on the basis of initial blow-out data are presented in the paper. Graphic materials and figure examples based on industrial data are given. Types of contaminations of ground and water environment in the case of ongoing blow-out.
Application of injection technologies in the device of ground constructions in different geological terms
(2009) Popov, A V; Tel'nih, N N; Caplin, E G; Dudlâ, Mikola Andrìjovič
A theoretical ground and examples of successful application of injection re-enforcement of soils for the improvement of his uniformity and rise of bearing strength is given in foundation of different buildings.
