In the last years, turbo-roundabouts replace conventional multi-lane roundabouts with aim to ensure a higher level of traffic safety and capacity. The most important feature of turbo-roundabouts is a spiral course of the circulatory carriageway allowing drivers easily pass through the roundabout from the entry пїЅ circulatory carriageway пїЅ to the exit without a need to change traffic lanes. Despite of an original proposal assuming the physical separation of spiral lanes, in many countries, the lanes are пїЅsepar...

This paper is devoted to the processes of curing low-viscosity epoxy resin waste under the influence of orthophosphor...

The dominating feedstock for biodiesel production is still a vegetable oil and cost of the oil composes 80-85% of the production costs, therefore the development of the more efficient methods for biofuel production from vegetable oil remains crucial. The transesterification of oil proceeds with the production of side product: glycerol, which cannot be a part of the composition of fuel. Chemical interesterification of oil with alkyl acetate produce a mixture of fatty acid esters and triacetin. Triacetin is a fuel b...

Ostrava Lagoons belong among the most polluted areas in the Czech Republic. According to the available information, about 200 000 t of sludge from the industrial processing of crude oil during the whole 20th century were disposed there. The sludge contains high levels of organic pollutants (PAHs, PCBs, C10 - C40 hydrocarbons), including toxic metals of anthropogenic origin (As, Cd, Cu, Hg, Ni and Pb). A number of autochthonous microorganisms were isolated from the lagoon sludge. This study focuses on the biodivers...

Westphalian A marine horizon Dunbarella is especially important for correlation of Carboniferous in the Lublin Coal Basin (LCB), and in the other basins of the Northwest European Carboniferous Basin (NWECB).

Lactoferrin (LF) is a globular glycoprotein with a molecular mass of about 80 kDa. It exists in two forms: apo- and hololactoferrin. Lactoferrin in the molecule has two domains that bind Fe3+ ions with high efficiency. The physiological properties of the protein are mainly due to binding to the iron of the active form by unsaturated iron (apolactoferrin). An iron-saturated form (hololactoferrin) is inactive. Raw milk contains mainly up to 90% apo-LF. Human milk is very rich in lactoferrin (about 1.7 g/L), and bovi...

In order to exclude the unprofitability of heavy oil deposits development in Russia and abroad, it is necessary to search and create new more advanced technologies for heavy oil and bitumen deposits development aimed at improving and creating technologies for increasing oil recovery, which allow developing fields with the greatest economic efficiency. This is due to both the structure of "unconventional" oil reserves and the need for more complete production of hydrocarbon reserves with sufficient high production ...

The exploitation of copper ore deposits in Polish underground mines is performed primarily by the use of blasting technology which seems to be relatively well suited to the hardness of the local rocks and to local mining and geological conditions. Blasting works are also recognized as an active method of seismic events prevention, conducted as group strain-release blasting within potentially instable main roof strata and in pillars. A notable number of recorded dynamic events can be clearly explained by the blasti...

The continuous development of techniques related to agriculture information management and GIS, with a close connection to sustainable development, are factors which contribute to the dissemination of precision farming.

A modern cadastral system should meet it requirements. These requirements relate mainly to the way of cadastral data access. The definition of cadastral system turns out to be not sufficient in the context of the on-line formula, because cadastral system is a distributed and extensive. The data of this system should be compatible with other information systems. In the presented paper, the author proposes the definition of a cadastral system relating to the most important element of the data quality which is the se...

Melanism is found in many animal species. This phenomenon is caused by a large amount of melanin pigment and causes an abnormal black or dark brown colour of the outer covers. Melanistic individuals are usually quite rare in nature. However, there are a number of examples indicating that melanistic colouring in animals can be adaptive under certain conditions and be supported by natural selection. These examples include the phenomenon of industrial melanism, described in the birch moth Biston betularia, as well as...
