Opis:
Many contemporary universities, also in Poland, focus mainly on their didactic and research-scientific activities and don't pay much attention to the needs of economic practice and the market.There is a small group of people of science who understand and in practice implement the economic mission of universities and research and scientific units, as key providers of new ideas in economy based on knowledgewhich is gaining more and more importance. Many scientists focus merely on the statutory activities of the institutions employing them, which now generally are limited to educating and scientific research.This to some extent results from statutory requirements ordering education and scientific research, promoted by the binding criteria of parametric assessment of scientific and research units. To some extent this is also the effect of convenience and lack of will to go beyond the well-known areas and modes of activity, typical of a substantial proportion of the scientific and didactic staff. Little interest in economic practice in many university circles may also in many cases be the effect of lack of sufficient knowledge about its needs and the inability to recognize them. This could suggest that people of science are not open to changes in their environment and that they are focused too much on their own areas of activity. One of the reasons for this state of affairs is limited knowledge of the people of science and mangers of science about the role and possibilities of contemporary marketing. In common understanding, marketing is associated with promotion and advertising. People who deal with economic practice, including scientists, regard marketing as an equivalent of advertising and promotion and they regard promotion as an art of manipulating recipients, which is not what fits into the scope of activities of an honest engineer, economic expert or scientist. This way many of them avoid the duty of proper understanding of the essence of marketing and the need to try to find out how marketing could be used to take advantage of the results of their scientific and research works. This issue is the leading plot of this article.

Opis:
This paper analyzes whether physicochemical properties significantly influence the occurrence of zooplankton in a brackish reservoir. The studies were carried out on the Vistula Lagoon in August and September from 2006 to 2009 at 32 research sites. The environmental conditions in the Vistula Lagoon varied widely. At the time of the investigation, 17 species of rotifers, six species of Cladocera, and ten species of Copepoda were noted, and the total density of plankton fauna ranged from 145 to 765 ind. dm3. Statistical analysis demonstrated a significant correlation between the occurrence of some zooplankton species and certain environmental parameters, whereas the sampling sites were grouped according to study years. The zooplankton systems recorded at the research sites in 2006 constitute the most disparate group. Thus, it can be concluded that physicochemical properties might significantly impact both individual species (depending on their environmental demands) and entire zooplankton clusters.

Opis:
The paper presents comparative analysis of operational parameters, smoke emission and toxic components contents in exhaust gases of a compression ignition engine fuelled with fossil diesel, commercial bio-diesel (fatty acid methyl ester) and their blend. Measurements were conducted on an older generation diesel engine equipped with in-line injection pump. Engine was operated in conditions of full load rotational speed characteristic and also ESC steady-state test cycle. Fourier Transform Infrared (FTIR) analytical system provided contents of 23 exhaust gas components. In particular chosen parameters of investigated fuels (on the base of quality reports), performance and fuel consumption characteristic versus rotational speed, smoke emission (D) and content of carbon monoxide (CO), unburned hydrocarbons (THC) and nitrogen oxides (NOx), sulphur dioxide (S02) and carbon dioxide (CO2) in exhaust gas of the engine fuelled with investigated fuels, emission of specific hydrocarbons of the engine fuelled with investigated fuels, of non-regulated compounds measured during the research, molar mass of analyzed exhaust compounds are presented in the paper.

Opis:
The paper discusses research assumptions and describes a test stand for the investigations of the sealing properties of the piston rings. The research stand includes an engine brake together with a control system, a research engine and a lubrication and engine thermal state stabilization systems. The engine was fitted with a research piston containing a measuring device enabling the recording of fast varying quantities such as the pressures in the space between the rings, axial displacements of the oil sealing rings in the piston grooves and the temperatures of the gas blown through the seal.
W artykule omówiono założenia oraz opisano zbudowane stanowisko do badania zjawisk związanych z uszczelniającym działaniem pakietu pierścieni tłokowych. Stanowisko składa się z hamulca silnikowego wraz z układem sterowania, silnika badawczego oraz układu smarowania i stabilizacji jego stanu cieplnego. Silnik wyposażony jest w tłok badawczy zawierający układ pomiarowy, umożliwiający pomiar i rejestrację szybkozmiennych wielkości, m.in. ciśnień w przestrzeniach międzypierścieniowych, osiowych przemieszczeń pierścieni uszczelniających w rowkach pierścieniowych tłoka oraz temperatur gazu przepływającego przez uszczelnienie.

Opis:
A dynamic response of a semi-trailer suspension to a real road profile under two different loads was investigated in this study. The trailer was a low loader for transporting heavy and large loads which configuration could be adjusted to the current needs. During the described investigation the vehicle was composed of: detachable gooseneck, maximally extended low bed and 5 hydraulically steered axles comprised 2-axle and 3-axle assemblies. The experiments were performed for unloaded and loaded with 60 tons trailer, that was equal to maximum trailer pay load. Acceleration measurements at unsprung and sprung parts of the vehicle were applied. As a test surface a railway track crossing was chosen. Acceleration time series were analysed by the means of power spectral density. The isolation of free vibration and forced vibration frequencies and effectiveness of suspension damping over wide frequency range was done. Two characteristic signal bands were identified. In the frequency range up to 10 Hz vehicle vibration energy decreased for the load increase for both, sprung and unsprung parts. In contrast, in the range between 10 and 25 Hz at higher load increase of vibration energy was noticed, however only at unsprung mass. Data analysis revealed complexity of vehicle vertical acceleration as a response to the road profile. Nevertheless, it allowed for estimation of the trailer dynamic loads under real road conditions.
