    Opis:
    Wildlife passages are an important tool to reduce negative effects of transport infrastructure on habitat connectivity and animal population viability. The aim of our study was to evaluate the use of two underpasses by medium-sized mammals. Both underpasses are situated in the area of the Rogów Forests, Central Poland, one of which is located under a road and the other under railway tracks. We used camera traps to monitor every wildlife crossing between February 2016 and December 2017. Four wild mammal species (roe deer, brown hare, red fox, martens) as well as domesticated cats and dogs were registered in the vicinity of the road underpass. Except for roe deer, the underpass was used (i.e. animals entered) by all of the listed species. The underpass was mainly used by brown hares in spring and by wild as well as domestic carnivores in autumn. Brown hares used the underpass mostly between 2 p.m. and 7 p.m., while foxes, cats and dogs at night. Near the underpass of the railway track, roe deer, wild boar, brown hare, red fox, raccoon dog, European badger, martens, European polecat as well as domestic dogs and cats were observed. Only wild boar and brown hare never entered the underpass. Roe deer used the underpass in May-June and September, wild carnivores in spring and dogs in summer. Only dogs used the underpass round the clock with roe deer, foxes, badgers and racoon dogs frequenting it at night. Domestic carnivores used both passages more often compared to wild mammals. Both underpasses were also heavily used by humans mostly in spring and at daytime. The usage of the underpasses by wildlife was strongly seasonal which could be related to increased animal locomotory acti- vity, i.e. during rut, dispersal of young. Furthermore, wild animals used the underpasses at night, when humans were less active indicating that human activity might have influenced the usage of the underpasses by wild mammals.

    wildlife−train collisions
    Opis:
    Where train tracks bisect moose habitat, trains may collide with moose, impacting the local population and creating a safety concern for rail traffic. Understanding the patterns underlying these collisions, is critical for helping managers choose the right mitigation methods to reduce mortality on railways. Our objective was to analyze the long−term temporal patterns of moose−train collisions. We used data on moose−train collisions from British Columbia (Canada) obtained from Canadian National Railways and British Columbia Rail Corporation. We analysed data from collision events that occurred between 1990 and 2010, excluding 1995−1996 for which there were no data. A total number of days, when moose−train collisions occurred (LD), and a total number of moose killed from collisions (LK) were calculated in annual, seasonal and monthly resolutions. We also investigated distribution of these data for day of the week. We used chi2 and Mann−Kendall tests to investigate whether LD or LK changed over time and Pearson correlation coefficient to relate these trends to the annual moose harvest in the analysed period. The number of days in which moose−train collisions occurred varied by year and by time of year. LD occurred most often in winter and least often in summer, with the highest number being recorded in February and the lowest in July. There were no significant differences in the number of moose−train collisions on various days of the week. We found no significant trends in LD for seasons, months (except for November) and weekdays for the period under investigation. In general, LK revealed a temporal pattern as LD, however number of killed moose was significantly lower on Fridays and Saturdays comparing to other week days. Because moose−train collision patterns did not change significantly between years, we assume that the temporal patterns exhibited in our study likely hold true from year to year and can be used to inform managers considering mitigation measures aimed at reducing moose−train collisions.

    Opis:
    While working on a system for verticalization and aiding the motion of the disabled, the problem emerged related to evaluation of the effect of individual traits of the users of the system on the obtained characteristics of the actuators. Studies that have been carried out so far were limited strictly to a case of an ordinary male. The traits of the user will significantly influence operation of the robot, therefore it was decided to carry out studies within a wide range of variability of the basic anthropometric traits. The paper presents a way of determining parameters, which were being changed during the studies, as well as a general structure of the simulation model. Then, a method of computing the energy consumed by the actuators is described, and results of the realized simulation experiments are presented.
    Podczas pracy nad systemem pionizacji i wspomagania ruchu osób niepełnosprawnych, pojawił się problem związany z oceną wpływu poszczególnych cech użytkowników systemu na uzyskane charakterystyki siłowników. Badania, które zostały przeprowadzone do tej pory były ściśle ograniczone do przypadku zwykłego mężczyzny. Cechy użytkownika znacząco wpływają na działania robota, dlatego zdecydowano się przeprowadzić badania w szerokim przedziale zmienności podstawowych cech antropometrycznych. Przedstawiono sposób określania parametrów, które były zmieniane w trakcie badań, a także ogólną strukturę modelu symulacyjnego. Następnie opisano metodę obliczania energii zużywanej przez siłowniki i przedstawiono wyniki zrealizowanych eksperymentów symulacji.

    Opis:
    W Zakładzie Konstrukcji Urządzeń Precyzyjnych na Wydziale Mechatroniki Politechniki Warszawskiej trwają prace nad systemem do pionizacji i realizowania chodu osób z bezwładem kończyn dolnych. Projektowanie urządzenia jest wspomagane badaniami modelowymi. W artykule przedstawiono symulacyjny model elektromechanicznej części systemu opracowany w środowisku Matlab/SimMechanics. Model wykorzystano m.in. do wyznaczenia zapotrzebowania energetycznego układów wykonawczych i oceny błędów odwzorowania profili ruchu.
    In the Division of Design of Precision Devices at the Faculty of Mechatronics of Warsaw University of Technology works there are performed upon a system for verticalisation and substituting gait for people with paresis (Fig. 1). Works are supported with simulation software. Simulation model of the system actuators is described in the paper. The purpose of simulation was to estimate energy consumption of actuators and to assess quality of their movements. Main assumption for the model is that mechanisms activating user's legs are of a planar kind. Matlab-SimMechanics mathematical environment was used for modelling. Structure of the model is presented in Fig. 2. Parts of human body are sources of load for actuators as described by eq. (2) and (3). Their parameters are inserted into "body" blocs (Fig. 3), which represent stiff elements of mechanisms in the model. Mechanical contact between the device and a ground was modelled as reaction forces occurring in "foot" parts of the device when distance between them and the ground is less than the assumed value. The drives of actuators' employ DC motors equipped with reduction gearboxes (Fig. 4). Typical equations (4) - (9) were used for modelling DC motors and gears. Input signals are reference angular displacements of joints expressed in the form of functions approximating experimental data (Fig. 5). Simulation experiments revealed strong relation between length of gait cycle and energy consumption of actuators (Fig. 6). Reduction gear ratio also influences energy needs as well as quality of the device movements (Fig. 8). The model is being currently modified and enhanced in order to be used at the next stages of design process.

    Opis:
    There has been designed a device for verticalization and aiding the gait of individuals suffering from paresis of the lower limbs. It can be counted in the category of so-called “wearable robots”, whose task is to replace or aid human limbs. Dependently on the function realized, these robots are classified into one of the following three groups: a) exoskeletons - strengthening the force of human muscles beyond their natural abilities, b) orthotic robots - restoring lost or weakened functions of human limbs, c) prosthetic robots - replacing an amputated limb. A significant feature of the device that has been designed is the fact that it has not to replace human limbs, but only restore them to their lost motor capabilities. Thus, according to the presented classification, it is an orthotic robot. Unlike in the case of the existing systems for verticalization, the gait is to be realized in a way that is automatic to the highest possible extent, keeping the user involved as little as possible, and the device is to imitate the natural movements of man with the highest fidelity. Within the works on the system for verticalization and aiding the motion, a simulation model of the device was created. It includes a structure of the robot, a model of the actuators and a model of the human body that constitutes the load for the driving units. Then, simulation studies were carried out, including evaluation of the power demand of the device as well as the influence of the gait rate and of the length of the steps on the operation of the system.

    Opis:
    Modernization of railways in Poland should ensure not only safety of passengers, but also limit their negative impact on the environment, especially possibility of train collisions with animals. The aim of the study conducted in the years 2007−2013 on the E20 railway Mińsk Mazowiecki−Siedlce were (1) to record places where animals cross the railway most often, both on the stretches secured and unsecured with sonic deterring devices (UOZ−1), and (2) to specify the number and locations of collisions of trains with mammals. Winter tracking along the railways identified 12 mammal species that crossed the railways. These included four ungulates (moose, red deer, roe deer, wild boar) and eight smaller mammals (red fox, marten, domestic dog, domestic cat, polecat, stoat, brown hare, red squirrel). The average number of tracks of all mammals was higher on the stretches with UOZ−1 than on the stretches over 100 meters away from UOZ−1 (1.52 and 1.01/100 m, respectively, p<0.0001). For ungulates it was higher on the stretches with UOZ−1 (0.66 and 0.38/100 m respectively, p<0.0005) as well. During the study 26 cases of animals kills as result of collisions with trains were recorded: 9 mooses, 2 red deer, 7 roe deer, 15 wild boars, 1 fox, 1 stone marten, 4 dogs. Most of these collisions took place out of the range of UOZ−1.

    The taxonomic position of the population of tree-like, mostly polycormic individuals of pines from the Mshana peat bog in the Gorgany Mountains (East Carpathians, Ukraine) has been studied on the basis of the morphological characteristics of cones and needles, and anatomical characteristics of the needles. These features have been compared with the surrounding Pinus mugo population as well as P. uliginosa, P. mugo, P. sylvestris and P. uncinata from natural populations of the taxa. Tree-like individuals were found to have the most similar needles to P. uliginosa, but most similar cone characteristics to P. mugo. It was concluded, that the tree-like population has a relic character and can present the trace of the early migration of P. uliginosa from the West and its hybridisation with P. mugo.

    Opis:
    Mechatronika, jako koncepcja budowy urządzeń jest obecna niemal we wszystkich działach techniki. Rozwój mikroprocesorowych układów przetwarzania danych, a także postęp w dziedzinie budowy układów wykonawczych i pomiarowych stwarzają możliwości realizowania przez urządzenia funkcji, które jeszcze do niedawna pozostawały jedynie w sferze marzeń. Postęp nie ominął również medycyny, a ściślej wyposażenia technicznego pracującego na rzecz osób chorych. Roboty ortotyczne, których szybki rozwój następuje w wielu ośrodkach naukowych na całym świecie, zastępują u ludzi utracone funkcje ruchowe. Autorzy pracują nad urządzeniem do pionizacji i wymuszania chodu osób z bezwładem nóg. W artykule przedstawiono koncepcję systemu sterowania opracowywanego urządzenia.
    Mechatronics seems to be nowadays the leading idea of design of machines and devices. Integration of mechanic devices with the powerful microelectronic technology forced synergy effects resulting in new applications also in medical domain. Here, wearable robots are most spectacular examples. They are person-oriented robots that may be defined as those worn by human operators, whether to support the function of a limb or to replace it completely. The authors focussed their attention on the development of an orthotic robot suited for people with paresis of lower limbs (Fig. 1). The role of the robot is to improve standard of life of handicapped people. However, for safety reasons, its usage needs additional assistance of third party persons. It leads to a conclusion, that control system of the device should be designed in such a way that movements of limbs are allowed only and only in cases when all safety conditions are fulfilled. Upon this statement, the device under design can be classified as a self optimising system. The general structure of such a system is shown in Fig. 2. This system consists of: knowledge base, multi- control subsystem, communication ports and inference machines. The block diagram of automatic control system is depicted in Fig. 3. The main purpose of knowledge base is to store and update reference data for decisions upon the device performance. This data contains records of values of selected signals, collecting information about the state of the device and a robot user, in order to detect non-safety behaviour. Tilt of the user's body and acceleration of its certain parts, as well as reaction forces between feet and crushes against ground can be considered as signals useful for decision making. A structure of the control system meeting the above considerations is presented in Fig. 4. A brief survey of data transmission protocols was carried out. A survey was focused on systems used for industrial applications taking into considerations its approved high immune against electromagnetic field transients and easiness of building redundant structures of communication networks and controllers. Finally, CAN standard was proposed as a communication protocol for the device broadly used in automotive industry (Fig. 5). In the conclusions future works are presented together with the risk analysis.

    Opis:
    Dioecy is a mating system in which a greater reproductive effort has been observed in one sex than the other. This is expressed in differences between the sexes in growth rate and spatial segregation. The spatial structure of Juniperus thurifera subsp. thurifera and Juniperus communis subsp. communis and growth rate of tree-ring width of J. thurifera were tested in different habitat conditions in Santo Domingo de Silos in northern Spain. We analyzed junipers growing on the eastern slope, with better habitat conditions, and the western, with poorer habitat conditions. The studies found that males of J. communis were taller when compared to the females, both on the eastern and the western slope. J. thurifera females were taller on the eastern slope (the better habitat), but shorter on the western slope as compared to males. J. thurifera males and females on the eastern slope had the greater tree-ring width in comparison with those on the western slope. The annual tree–ring width of males dominated over females on both slopes at first, probably from the time of sexual maturation. However, these differences persisted to the end of the analyzed period only on the poorer western slope. The growth rate of females and males after several years was equal on the eastern slope. Spatial segregation has not been shown, probably due to the homogeneity of the habitat on both slopes. Studies have shown that the decrease of growth rate in J. thurifera females can occur only in the poorer habitat conditions.

    Opis:
    Mechatronics is nowadays a dominating concept in design of various kinds of systems and technical devices. High speeds of data processing by control units of mechatronic systems, as well as high dynamics of their actuators allow the systems to be applied in wider fields. This refers to the medicine as well, especially while making attempts to replace lost human motor abilities by means of robots aiding the man. These devices can be divided into three groups: exoskeletons designed to strengthen the natural force of human muscles, orthotic robots that restore lost or weakened functions of human limbs, and prosthetic robots replacing an amputated limb. The first and the third group are known quite well, whereas the orthotic robots are at an initial phase of their development. The authors have worked on a device for aiding the motion of disabled people suffering from paresis of the lower limbs. The paper presents a concept and a structure of the system that has been created, comparing it with similar devices that have already existed. There are indicated some connections and areas where the subunits merge, as well as the rules of their working with the user.

    Opis:
    Divergence in genetic as well as phenotypic structures can be expected in species with disjunctive geographic ranges and restricted gene flow among isolated populations. Dwarf mountain pine has such a disjunctive geographic range in the mountains of Central Europe. We hypothesised that populations of Pinus mugo from the Giant Mts. differ from Alpine and Carpathian populations to a greater extent than differentiation within these regions; furthermore, these differences would be detectable at both the genetic and phenotypic levels. To verify this hypothesis, the diversity and differentiation within and among eleven populations from the Giant Mts., Carpathians and Alps were analysed using 19 isozyme isozyme loci, 17 needle and 15 cone morphological characters. Moreover, the data on 10 chloroplast microsatellites used in the previous study, were reanalysed. The differences between the three regions were greater than among populations within them. The microsatellites and isozymes clearly differentiated between regions, while in the multivariate analyses of cone and needle characters the Alpine and Carpathian populations were intermingled but distinct from those sampled in the Giant Mts. The significant genetic structuring among regions may result from an ancient fragmentation and long lasting geographic isolation between the Giant Mts., Alps and Tatras. The populations from the Giant Mts., the northernmost within the geographic range of P. mugo, presented lower level of genetic variation then those from the Alps and Carpathians. The pattern of genetic structure observed in dwarf mountain pine may be characteristic of wind-pollinated trees with a disjunctive geographic distribution

    Opis:
    Vietnam is one of the main centers of generic diversity for Juglandaceae worldwide. In this study, we present for the first time a province-wide distribution of all 3 subfamilies, 7 genera, and 11 Vietnamese species, and give an update on the habitats of all Vietnamese Juglandaceae species, their uses, and current threats. Juglandaceae are found throughout Vietnam. However, most species occur predominantly in the north- ern part of the country between 600 and 1200 m. Some taxa range is found extensively from sea level up to 2,500 meters above sea level. According to the IUCN Red List, Rhoiptelea chiliantha, Carya sinensis, and Pterocarya tonkinensis are threatened while Engelhardia spicata, E. serrata, Alfaropsis roxburghiana, Pterocarya stenoptera are classified as least concerned (Carya tonkinensis is threatened locally, and Engelhardia spicata var. colebrookiana and Platycarya strobilacea merit “threatened” designation in Vietnam’s Red Data Book. The most frequent threats are logging, land-use change, and habitat destruction due to artificial wood planta- tions or road construction. Until now, no conservation measures have been applied for any of the species in Vietnam, although some species occur in national parks. Our study gives an important update on the current diversity and distribution of Juglandaceae in Vietnam. We point out the need for a correct assessment of the threat status of various species on a national and international scale to protect the rarest and most endangered of them. Further research, the use of various forms of protection of individual taxa and/or their habitats, and drawing the attention of an international group of researchers to the urgent need to work together to protect biodiversity in Vietnam hot spots are necessary.

    Opis:
    The Jagiellonian Positron Emission Tomograph (J-PET) collaboration is developing a prototype time of flight (TOF)-positron emission tomograph (PET) detector based on long polymer scintillators. This novel approach exploits the excellent time properties of the plastic scintillators, which permit very precise time measurements. The very fast fi eld programmable gate array (FPGA)-based front-end electronics and the data acquisition system, as well as low- and high-level reconstruction algorithms were specially developed to be used with the J-PET scanner. The TOF-PET data processing and reconstruction are time and resource demanding operations, especially in the case of a large acceptance detector that works in triggerless data acquisition mode. In this article, we discuss the parallel computing methods applied to optimize the data processing for the J-PET detector. We begin with general concepts of parallel computing and then we discuss several applications of those techniques in the J-PET data processing.

    Opis:
    The positron annihilation lifetime spectroscopy was applied to the samples of the human uterine leiomyomas and the normal myometrium tissues taken from the selected place of the uterus during a surgery. The method indicated differences in values of the measured positron annihilation lifetime spectroscopy parameters (lifetimes and intensities) between healthy and diseased tissue samples. The additional measurements were performed either in darkness or in presence of visible light which influenced the free radicals present in both kind of tissues and, as a result, made changes in free annihilation and o-Ps decay lifetime and intensity values.

    The Jagiellonian positron emission tomograph project carried out in the Institute of Physics of the Jagiellonian University is focused on construction and tests of the first prototype of PET scanner for medical diagnostic which allows for the simultaneous 3D imaging of the whole human body using organic scintillators. The J-PET prototype consists of 192 scintillator strips forming three cylindrical layers which are optimized for the detection of photons from the electron-positron annihilation with high time-and high angular resolutions. In this article we present time calibration and synchronization of the whole J-PET detection system by irradiating each single detection module with a ²²Na source and a small detector providing common reference time for synchronization of all the modules.

    Opis:
    A method for creating linearly polarized positrons and ortho-positronium (o-Ps) atoms with the J-PET detector is presented. The unique geometry and properties of the J-PET tomography enable one to design a positron source such that the quantization axis for the estimation of the linear polarization of produced o-Ps can be determined on the event by event basis in a direction of the positron motion. We intend to use ²²Na or other β⁺ decay isotopes as a source of polarized positrons. Due to the parity violation in the beta decay, the emitted positrons are longitudinally polarized. The choice of the quantization axis is based on the known position of the positron emitter and the reconstructed position of the positronium annihilation. We show that the J-PET tomography is equipped with all needed components.

    Opis:
    Positron annihilation lifetime spectroscopy has shown to be a powerful tool to study the nanostructures of porous materials. Positron emission tomograph is a device allowing imaging of metabolic processes e.g. in human bodies. A newly developed device, the Jagiellonian PET will allow positron annihilation lifetime spectroscopy in addition to imaging, thus combining both analyses providing new methods for physics and medicine. In this contribution we present a computer program that is compatible with the Jagiellonian PET software. We compare its performance with the standard program LT 9.0 by using positron annihilation lifetime spectroscopy data from hexane measurements at different temperatures. Our program is based on an iterative procedure, and our fits prove that it performs as good as LT 9.0.
