Opis:
The aim of this article is to formulate guidelines for locating benches in rural public spaces. It is a summary of the results of a qualitative research involving 67 users of urban benches, conducted with the application of individual in-depth interviews, and the results of a literature review on the manner in which rural public spaces are equipped. The obtained results pertain to the use of benches in rural public spaces in the context of their integration and semantic potential (symbolic values). The conclusions are presented in the form of general guidelines. Public consultation should be an important element in deciding how to equip rural common space with benches. Local communities ought to be included in the decision-making process, from the stage of the assumptions of the design concepts to the stage of realization. It is advisable to adjust the form of benches, their number, orientation and location to the nature of public space and expectations of their future users. At the same time, the overall structure of public space and its main functions should be taken into account. Properly selected and placed benches can support the process of community structuring and may be a part of the equipment of public space which integrates the local community. Locating benches opposite each other or in the shape of the letter L or C promotes integration. Designing space according to the safe space standards can be a solution for sites conducive to drinking alcohol. Locating benches in the vicinity of streets, at the fence bypass, is a traditional way. Benches with atypical forms or functions located in common areas may contribute to the extraction or strengthening of the local identity.

Opis:
The objective of this publication is to present the changes that are currently made to the tyre structure in order to reduce its rolling resistance including the rubber compound, tread pattern and tyre support structure. Based on a broad literature review the authors present a history of changes introduced in the construction of tyres aimed at reducing their share in the energy losses needed to overcome the resistance of rolling wheels in the car's movement (at present it reaches even 50%). They indicate a significant conflict resulting from the rubber properties using the data sets available on the labels of summer and winter tyres in which the improvement of wheel adhesion leads to increased rolling resistance. In the next part, the basic factors determining the rolling resistance of tyres are approximated, focusing on those related to their construction. The influence of the rubber loss factor is described which values at different deformation frequency (turning the wheel 101-102 Hz and its braking at 104-105 Hz). It determines the interaction of the rubber with the road surface. Various ways of actions are shown to reduce the losses occurring during the deformation of the tyre: the use of silica as a rubber filler and the introduction of nanotechnology to control the rubber crosslinking process, reducing the volume of rubber used to build the tyre coating, simplifying the tread pattern and changing the tyre diameter size to a larger one (treatment used in electric cars). Particular attention was also paid to the weakness of the changes, i.e. the increase of the noise generated by the more elastic coating of the tyre and the possible directions of counteracting this phenomenon were signalled.

Opis:
The characteristics of the car tire, and especially its deformation and interaction road, are mainly factors affected the energy consumption of the vehicle and consequently the amount of fuel consumption and emissions to the environment the harmful exhaust gas components. It is estimated that approximately 80-90% of the total energy losses (rolling resistance) are due to internal tire friction, which occurs during its deformation, the remaining 10-20% are ventilation losses, tread face interaction with the road surface and cyclical compression and expansion of air enclosed in the tire. Non-pneumatic tires (NPT) (as a direction of development) are the alternative solutions for conventional tires. Their advantages are as follows maintenance-free and the resistance to typical for pneumatic tires mechanical damages can be a major cause of their widespread use in future (and thus electric) cars. In the available publications, the results of the estimation of the features NPT based on numerical simulations are only presented. There is lack of experimental research results concerning real objects, which determine their driving properties. Presented work is an attempt to check how the change in wheel structure affects the energy consumption of rolling wheels. Research objects (non-pneumatic tire and pneumatic tire) were selected for the size and destination compatibility. Experimental research were carried out at a universal quasi-static tire testing station, which is located at the Institute of Mechanical Vehicles and Transport at the Department of Mechanical at the Military University of Technology. According to the authors, the obtained results can be an interesting and unique supplement to the problem of assessing the properties of new and future (non-pneumatic tire) construction of vehicle wheels.

Opis:
This paper proposes four different cost-effective configurations of a hybrid energy storage system (HESS) in an electric city bus. A comparison is presented between a battery powered bus (battery bus) and supercapacitor powered bus in two configurations in terms of initial and operational costs. The lithium iron phosphate (LFP) battery type was used in the battery bus and three of the hybrids. In the first hybrid the battery module was the same size as in the battery bus, in the second it was half the size and in the third it was one third the size. The fourth hybrid used a lithium nickel manganese cobalt oxide (NMC) battery type with the same energy as the LFP battery module in the battery bus. The model of LFP battery degradation is used in the calculation of its lifetime range and operational costs. For the NMC battery and supercapacitor, the manufacturers’ data have been adopted. The results show that it is profitable to use HESS in an electric city bus from both the producer and consumer point of view. The reduction of battery size and added supercapacitor module generates up to a 36% reduction of the initial energy storage system (ESS) price and up to a 29% reduction of operational costs when compared to the battery ESS. By using an NMC battery type in HESS, it is possible to reduce operational costs by up to 50% compared to an LFP battery ESS.

Opis:
The paper proposes to apply an algorithm for predicting the minimum level of the state of charge (SoC) of stationary supercapacitor energy storage system operating in a DC traction substation, and for changing it over time. This is done to insure maximum energy recovery for trains while braking. The model of a supercapacitor energy storage system, its algorithms of operation and prediction of the minimum state of charge are described in detail; the main formulae, graphs and results of simulation are also provided. It is proposed to divide the SoC curve into equal periods of time during which the minimum states of charge remain constant. To predict the SoC level for the subsequent period, the learning algorithm based on the neural network could be used. Then, the minimum SoC could be based on two basic types of data: the first one is the time profile of the energy storage load during the previous period with the constant minimum SoC retained, while the second one relies on the trains’ locations and speed values in the previous period. It is proved that the use of variable minimum SoC ensures an increase of the energy volume recovered by approximately 10%. Optimum architecture and activation function of the neural network are also found.

Opis:
The methodology of research and the inspection of the main transmission gearboxes of multi axles armoured vehicle ROSOMAK under operating conditions are described in this article. Tests are carried out on the bench to allow force transmission changes to the extent similar to the loads that occur during vehicle operation. Transmission gear boxes are driven by an internal combustion engine 359 through a reducer (standard engine gearbox). This reducer increase torque and decrease shaft speed similar to condition in the vehicle. On the other side of the transmission, multiplying gearbox coupled with a brake dynamometer were placed. It increases speed according to requirements of the work field of the dynamometer W-230. The combustion engine made possible to measure vibration of transmission gearboxes under the high torque. The torque is greater than obtainable by using electric motors. The value of the inertia moment loading axle shaft was determined using a simplified kinematic diagram. During the tests, vibration were measured at selected points of the housing using different methods of attachment of vibration transducers. First, the screw for assembling the vibration sensor was glued to the hull of gearbox. Second, the sensor was connected with gearbox by permanent magnets. Third, the sensor was used as a hand probe. The results of vibration measured by these methods were compared. Temperature of the gearbox was also measured by using thermocouples and thermovision methods. Selected results are presented and analysed of vibration transmission and its temperature at selected working conditions.

One possible method of drinking water treatment is chlorine dioxide disinfection. This technology, however, requires reliable control of its byproducts, including chlorite ions., which pose a threat to human health. In this paper an original procedure for flow indirect determination of chlorite in drinking water was described. This method relies on oxidization of chlorite ions by iron(III) in acid environment measurement of the spectrophotometric signal for the phenanthroline/iron(II) complex. The determinations were carried out by flow analysis with the use of a dedicated set of flow instruments. The method was used for analysis of natural samples collected from various water intakes in Kraków. The new analytic approach was compared with the routinely applied ion chromatography method.
Jednym ze sposobów uzdatniania wody pitnej jest jej dezynfekcja tlenkiem chloru(IV). Ważnym zadaniem, jakie wiąże się jednak z tym procesem, jest wiarygodna kontrola zawartości produktów ubocznych w postaci jonów chloranowych(III), stanowiących duże zagrożenie dla zdrowia człowieka. W pracy opisano oryginalną procedurę pośredniego oznaczania chloranów(III) w wodach. Polega ona na wykorzystaniu reakcji chloranów(III) z jonami żelaza(II) w środowisku lekko kwaśnym i pomiarze spektrofotometrycznego sygnału dla jonów żelaza(II) w obecności 1,10-fenantroliny. Oznaczenia wykonywano techniką przepływową z użyciem dedykowanego zestawu instrumentalnego. Metodę zastosowano do analizy próbek pobranych z różnych ujęć wody pitnej w Krakowie. Dokonano porównania opracowanego podejścia analitycznego z rutynowo stosowaną metodą chromatografii jonowej.

Opis:
The blooming wild plants in the vicinity of orchards may attract adult Syrphidae to these cultivations. Hence in 2008–2010 studies were conducted around Czempiń (western Wielkopolska) which covered the occurrence of the imagines of 5 dominant predatory Syrphidae species in apple orchards and on their edges. The phenology of Episyrphus balteatus (De Geer), Eupeodes corollae (F.), Melanostoma mellinum (L.), Sphaerophoria scripta (L.) and Syrphus vitripennis Meigen in apple orchards as well as in the neighbouring shrubberies and on the side of the road overgrown with trees and bushes was analysed. A greater abundance of imagines of the studied species was found on the edges than in the apple orchards. Also a preference for either orchards or their sides was indicated for Syrphidae, as they appeared in these biocenoses earlier or later, but not at the same time. A correlation between a mass catch of Syrphidae in the orchards and their edges was found. It was shown that the blooming plants of orchard edges, such as Tilia cordata, Symphoricarpos albus, Cirsium arvense and Galium aparine, could attract Syrphidae imagines to the orchards.

Plant communities which form orchard edges are a vital element of ecological infrastructure enriching these agrocenoses. The research was conducted in an orchard environment made up of apple orchards and their edges in the form of agricultural cultivations, tree clumps and a road lined with trees and shrubberies. The study aim was to determine the impact of the orchard edge plant diversity onto the number and abundance of Ichneumonidae subfamilies in the orchards. The study showed that orchard environments made up of an apple orchard and edge plants of various species create better living conditions for Ichneumonidae parasitoids than the environment of an orchard and neighbouring agricultural cultivations. The diversity of orchard edge plants positively influences the abundance of the Ichneumonidae subfamilies rather than the number of subfamilies in the orchard. In the orchard habitat the following dominant subfamilies were found: Campopleginae, Cryptinae, Orthocentrinae and Pimplinae. These entomophages may control the abundance of pests infesting orchards.

The paper describes results of research on heavy vehicle tyre with Run Flat VFI insert. The experiment has included the determination of heat generation, rolling resistance, and radial stiffness of two different tyre designs (textile and steel carcass). The results have been used for the purpose of evaluation of tyre operating characteristics. The study included research on non-inflated tyre properties. The purpose of the paper is to determine characteristics of the tyres equipped with inserts, which are essential for driving wheeled APCs. The inserts are composed of polymer rings mounted on the rims inside the tyres. If the inflation pressure of the tyre is very low or if there is no inflation pressure at all, the ring transfers the loads imposed on the tyre to the rim. Usually in such a case, there is a contact of the ring and inner surface of the tyre tread area. Laboratory facility for surveys of heavy vehicles tyres, summary characteristics of radial stiffness and hysteresis of test tyres, temperature distribution on the external surface of the test tyre, comparison of radial characteristics of the tyres tested, example of stiffness characteristics, distribution of temperature on the side of tyre during the road test and carcass damages on the flat tyre are presented in the paper.
