Opis:: The irregularities of evolutionary development, continuous improvement of environmental component into transport and raise many unsolved problem in the fields of transport in logistics systems and material flows management. The city parameters analyses had highlighted connections with transport services technology. Also the distribution stage of the logistic chain, which consists of following market participants: incoming material flow, retailers and Transportation Company (carrier) in different cities has been considered. Transportation service is made by road transport. The paper compares results of transportation servicing in different cities and logistic chains with same technology. As performance indicator net present value has been used. Existing criteria for evaluating the effectiveness of distribution of material flows does not sufficiently take into account the time value of money and possible options for investment, so when estimating the performance of servicing of business investment indicators should be used. Paper should elucidate the impact of cities on the transport service efficacy. Practical suggestions on logistics system functioning and transportation service of retailers in urban area have been proposed. Obtained results discovered overall impact of city’s parameters (density of streets and roads network’ irregularity factor; automobilizationlevel; urban square; scheme of road network; city radius) on logistics according to model which include more than 50 parameters and allows finding regularities of changing logistics efficiency on them.

Opis:: The modern person in an era of information breakthrough faces the problem of choosing and processing information coming to her. Human activities in the systems "driver - vehicle - road - environment" - not an exception. The role and importance of information in all spheres of human activity have increased significantly. The paper aims to find and assess the patterns of information flow impact on the driver performance in the "driver - vehicle - road - environment" system. Electroencephalography (EEG) method using the Neurocom hardware and software complex used to determine the change in the electrical activity of the driver's brain during the processing of input information; electrocardiography method using the hardware and software complex «Cardiosens», used to determine the fatigue level of the driver during research; tabular method of double letter cancelation test, involved in determining the time of distraction from the performance of the driver's core activity in laboratory experiments. Using mathematical modelling methods and methods, mathematical models of EEG and ECG parameters influence on the time of distraction from execution by the driver of the main activity were obtained. Regression models of the influence of the aggregate of the quantitative characteristics of the intensity of fast (beta-rhythm – β and gamma-rhythm – γ ) and slow (delta- rhythm – δ and theta-rhythm –θ) EEG signals are proposed. The regression equations obtained for determining the regularities of the influence of information flow on the results of activity of road users are defined. Set up that the time of the driver's distraction from performing the core activity can reach from 0,94 s to 4,77 s depending on particular conditions. Information flows arising from the location of noticeable advertising in the driver's field of vision when driving a vehicle, distract his attention from 0,23 s to 2,81 s. The practical significance of obtained results is the possibility to use them in coordinating the location of advertising structures and organizing the work of drivers while driving a vehicle.

Opis:: The article presents results of physical modelling of processes of plastic working of the modified Zr-1%Nb zirconium alloy, obtained using different methods of the plastometric testing. The „Gleeble 3800”‚ metallurgical process simulator, a DIL805 A/D dilatometer with a plastometric attachment, and a „Setaram‚ plastometer were used for testing. Based on the obtained testing results, the values of the yield stress and limiting plasticity of the tested alloy were determined for wide ranges of temperature variation (T=20÷950°C) and strain rate variation (ε=0.1÷15.0 s^-1) under continuous loading conditions. It was found that by using different testing methods, different alloy properties, characteristic for a given plastic working process, could be obtained.
W artykule przedstawiono wyniki modelowania fizycznego procesów przeróbki plastycznej modyfikowanego stopu cyrkonu Zr-1%Nb, otrzymane za pomocą różnych metod badań plastometrycznych. Do badań zastosowano symulator procesów metalurgicznych „Gleeble 3800”‚ dylatometr DIL805 A/D z przystawką plastometryczną i plastometr „Setaram‚. Na podstawie otrzymanych wyników badań określono wartość naprężenia uplastyczniającego i plastyczności granicznej stopu dla szerokiego zakresu zmian temperatury (T=20÷950°C) i prędkości odkształcenia (ε=0.1÷15.0 s^-1), w warunkach obciążania ciągłego. Stwierdzono, że stosując różne metody badawcze można uzyskać inne własności stopu, charakterystyczne dla danego procesu przeróbki plastycznej.

Opis:: Fungi of the Aspergillus genus are widely distributed in nature, including more than 300 species, but only a few of them are pathogenic for humans and animals. Aspergillus can grows on organic substrates in soil, on plants. Spores are constantly present in air, and with it food, household items, outer integument and mucous person causing the disease to cause aspergillosis. When aspergillosis usually affects the respiratory system, in some cases, skin, kidneys, brain, eyes. Invasive pulmonary aspergillosis is associated with high mortality. In recent years, the number of cases has increased. At risk are people with immune deficiencies. Crucial in the fight against this disease promptly started playing antifungal therapy and early diagnosis. When selecting tests are important technical and economic indicators of the complexity or simplicity the study, its reproducibility, the applicability of automated screening and cost analysis. In the present article we have analyzed and compared different methods for aspergillosis diagnostics. Biotechnological approaches for development of allergy/aspergillosis diagnostic preparations also have been discussed.
