Abstract

The aim of this work is purification of contaminated soil from manufactured gas plants MGP, which arc not used. Prepared chromatographic methodologies, which allow qualitative identification and quantitative determination of individual aliphatic and aromatic (TAH, PAH) hydrocarbons in the soil from the selected MGP, arc presented. The results of the research on remediation of the soil polluted with petroleum hydrocarbons (TAH, PAHs) in semi-field conditions arc discussed. Application of basic biorcmcdiation and bioaugmcntation with indigenous microorganisms, enriched with PAH biodegradable fungi, resulted in reduction in amount of 5- and 6-polycyclic aromatic hydrocarbons. The research enables control of remediation progress, selection of optimal doses of biogenie compounds and determines the time of the process. The entire cycle of soil remediation was monitored with the use of gas chromatography (GC). Estimation ofbiodcgradation degree of individual aliphatic hydrocarbons (alkancs) was based on changes in their concentration in the soil and determined by biodegradation indicators: C,/pristanc and C,/phytanc ratios. Attention was paid particularly to biodcgradation of polycyclic aromatic hydrocarbons (PAH), which were observed in substantial concentrations in the polluted soil. The elaborated chromatographic methodology of PAH determination in the soil enabled estimation of a biodcgradation rate referring to individual compounds. Moreover, attempts to create a TAH biodcgradation model with the use of C30-l 7a(H),2 l l3(H)-hopanc were undertaken.

Abstract

Even the best project of a wind power plant (WPP) can fail if there are not favourable legal regulations for its completion. Most of the research has dealt with identification of various obstacles to implement WPP (political, social, legal, environmental). Analyses of legal barriers (LBs) have been usually made at a high degree of generality. This paper offers a thorough overview of LBs for localization of WPPs in Poland. This is the country where restrictive regulations have blocked the possibility of implementing such projects in many areas. Unfriendly law may persuade investors to choose worse wind turbines foundation conditions. In our research we focus on a problem little dealt in scientific studies, i.e. on the localization of WPP in difficult geotechnical conditions. The article presents the analytical engineering method, which includes the mutual influence between foundation piles in carrying on the construction load on a subsoil. The paper presents the geotechnical parameters responsible for calculation outcomes, the theoretical basis of the curve analysis method of settlement of a single pile and of the calculation of piles settlement working in a group and fastened with a stiff head. It also shows the effect of pile arrangement in a foundation and a load distribution of in-dividual piles, as well as a settlement and leaning of foundation of wind power turbine towers. The method enables a more precise, safer and optimal design of a wind turbine foundation.

Abstract

Research in Hornsund (SW Spitsbergen) aimed to determine time distribution of heat flux in various soils of Arctic periglacial zone in spring and summer. Typical soils were analysed: tundra gleyey cryogenic soil (Pergelic Cryaquent), tundra peaty soil (Pergelic Histosot) and arctic desert soil (Pergelic Cryorthent). Research sites were located in low plains not covered with ice, near a sea, at 7—13 m a.s.l. Heat flux in soils was measured and recorded automatically every 60 s throughout a whole observation period and concurrently at three sites. In spring and summer intensive heat accumulation was observed in all examined soils. Independently on the weather, a cryogenic gleyey soil received greatest heat throughout a day. Environmental conditions have distinct influence on heat resources in soils.

Abstract

The paper presents unequivocal arguments in favour of the procedural nature of the canonical confrmation of holiness, as regards the process of beatifcation and canonization on the diocesan level. It was also underlined by Cardinal Prefect of the Congregation for the Causes of Saints on 18 February 2008 in his intervention, concerning the Instruction issued by the Congregation and approved by the Pope, on stricter obeying the existing law. It was clearly stressed by the Cardinal that the document is not legislative in nature but is an administrative act of the Congregation for the Causes of Saints. He also rejected the common and false opinion that Pope John Paul II allegedly replaced procedural methodology in canonical processes of the confrmation of holiness by a methodology of historical-critical research. The Italian term “inchiesta” is to be understood not as a solely scientifc inquiry but also procedural. The interpretation of the internal regulations of the Congregation and its doctrine are in favour of the canonical procedure, which is analogous to ordinary canonical processes both in the diocesan and in the Roman phase. Eventually, the paper refers to the nature of the fnal decision of the pope in cases of beatifcation or canonization, which proves that the canonical confrmation of holiness in the Church is complex and unique to this kind of cases.
