Opis:: Specimens of the genus Sorbaria cultivated in Polish dendrological collections have been examined. It appears that in Poland only 3 species are cultivated: S. sorbifolia, S. kirilowii and S. tomentosa. Some supposed hybrids of S. sorbifolia and S. kirilowii or S. tomentosa have been found in the Arboretum in Kórnik and Botanical Gardens in Poznań and Warsaw. A new, supplemented distribution map, a key to identification, and descriptions of the species occurring in Poland are given.

Opis:: The subject of this article is to test the shear strength of the anchorage, based on diagonal brackets. The tests were carried out on six three-layer samples with a size of 40 x 20 x 17 cm. The samples have been designed to represent a section of a three-layer wall in large-plate buildings and made on an adequate scale with wire mesh reinforcement of Ø 3 mm and a mesh size of 3 x 3 cm. In three samples Ø 6 mm Ø hangers with a diagonal support arm were concreted, and in three others with a „V” shape. The hangers were interlocked with Ø 6 mm anchoring rods to stabilize the mesh embedded in the texture layer. The samples were made of concrete of class C 12/15, while the inner layer was thermal insulation in the form of expanded polystyrene. Tests of the resistance of the pull-out anchors were carried out using Hydrajaws 2008 Pull-out Tester. Each anchor was tested individually. Bonded anchors M 12 were used. The results were summarized in 15 tests (9 diagonal anchors and 6 points). The tests were carried out until the anchor fixings were destroyed. The increase in force during a single attempt was determined on the basis of a video recording in relation to each attempted extraction. When attempts were made to remove the diagonal anchors, steel brackets and angular wooden washers were used to achieve the effect of axial removal of anchors. The role of diagonal anchors in the work of the three-layer element has been discussed.

Opis:: The aim of the article was to verify the hypothesis that humidity, temperature and light con- ditions play a fundamental role in the distribution of Frullania dilatata within the forest complexes in the Wigry National Park. 41 monitoring localities were selected in places of epiphytic liverworts occurrence (22 sites with F. dilatata, 19 – without these plant). Humidity and temperature were recorded hourly during one year. Light conditions on the tested sites were determined on the basis of hemispherical photos. Additional parameters were calculated based on the digital terrain model in the SagaGis program. The results indicate that the hypothesis is false.

Opis:: A simple approach for CMOS integrated circuit (IC) design taking into account a process variability and oriented towards optimization of a parametric yield has been presented. Its concept is based on cumulative distribution functions of random variables representing IC performances subject to process variations. In the method it has been assumed that CMOS process statistical data are expressed in terms of so-called process parameter distributions. Thus the design centering is done via layout parameter tuning. The approach relies on maximizing the probability that random variables corresponding to IC performances remain within the performance boundaries. Also, a methodology for statistical characterization of CMOS process has been briefly described. Finally, the method operation has been illustrated using analytical and SPICE models of CMOS inverter, operational amplifier and ring oscillator.

Opis:: W pracy oceniono możliwości monitorowania trójfunkcyjnych reaktorów katalitycznych silnika o zapłonie iskrowym za pomocą wąskopasmowych czujników stężeń tlenu. Zaproponowano metodę symulacji procesu dezaktywacji polegającą na wymianie wkładów aktywnych reaktora na wkłady nieaktywne. Dla potrzeb badawczych zdefiniowano wskaźnik monitoringu reaktora katalitycznego. Zaproponowano dwie metody wyznaczenia wskaźników monitoringu: metodę wykorzystującą obliczenia dyskryminant amplitudowych i metodę wykorzystującą obliczenia funkcji interkorelacji sygnałów z czujników stężeń tlenu. Porównano możliwości monitoringu pracy reaktora w ustalonych warunkach pracy silnika spalinowego i pracy reaktora w nowym europejskim teście jezdnym podczas jego symulowanej dezaktywacji. Na podstawie wyników badań porównano przydatność wyznaczonych wskaźników monitoringu pracy reaktora.

Opis:: This paper is devoted to a practical verification of applying the Phong model, conducted based on available survey data obtained in field conditions. This model has already been described in previous articles, in which authors, using surveys performed in laboratory conditions, showed how to change the shape of the Phong model function depending on the material on which the laser beam falls. In subsequent publications, the focus was on the relationship between the incidence angle and the maximum distance that can be measured by the rangefinder. The measuring data were obtained as a result of scanning the furnace wall in the heat and power station in Pruszków, Poland with the use of reflectorless laser. The presented way of computation has been substantiated on the basis of calculated quantities, incidence angle and empirically defined parameters of the Phong model.

Opis:: In this paper the active method of three way catalyst monitoring by use of wideband combustion mixture composition sensor was described. This method relays on three way catalyst activity decrease by determination of it oxygen capacity decrease monitoring. Determination of catalyst oxygen capacity decrease was done by comparison of signals from wideband and binary combustion mixture composition sensors. These sensors were mounted before and after investigated catalyst. In this paper was described the test bench in which modified catalyst was used. The catalyst was modified to simulate it activity decrease. Paper contains the investigation procedure and also static and dynamic characteristics of wideband combustion mixture composition sensor. A hand of received results the characteristic of binary combustion mixture composition sensor reaction time on combustion mixture change in function of reactor activity was determinate. From received results the index of reactor oxygen capacity decrease was also determinate. Received results showed also that this method can be used for precise controlling of three way catalysts activity for on board diagnostic systems purposes. Additionally this method allows concluding on toxic gases emission in NEDC tests at steady state engine work cycle.

Opis:: Thuja ×soeegaardii, a hybrid of Th. plicata Donn ex D.Don and Th. standishii (Gordon) Carrière, is described as a new nothospecies from the Kórnik Arboretum, Poland, based on plants obtained in 1988 from the Botanical Garden in Gothenburg, Sweden. The hybrid was found for the first time at the Hørsholm Arboretum, Denmark, in 1938, among seedlings grown from seeds collected from Thuja standishii. Plants grown from rooted scions of this hybrid were planted in several places within the Hørsholm Arboretum. Soon, the hybrid plants were gifted to the Botanical Gardens in Copenhagen and Gothenburg as well to the Poulsen’s Plant Nursery in Kvistgård. In 1967 seedlings were sent from Kvistgård to the National Arboretum in Washington, where one of them developed into a particularly showy, lush and vigorous plant characterized by a dense, narrow, conical crown. The offspring obtained from rooted scions turned out to be very drought and wind-resistant, especially suitable for the formation of tall hedges and windbreak screens. This plant, now very widespread in cultivation, especially in the United States, goes by the name of Thuja ‘Green Giant’. In terms of morphology, many features of Th. ×soeegaardii are intermediate as compared to the parent species. From the Th. plicata, it differs by the following characteristics: leaves not or only weakly shining above, lateral leaves with inwardly curved (not straight) apices, the apical part of lower central leaves thickened and slightly bent from the stem (not appressed), glands on central leaves only weakly visible, central leaves of primary shoots acuminate (not long acuminate) and seed wings sparsely papillose in the upper part (only rarely smooth). From Th. standishii, it can be distinguished by the less glaucous upper leaf surface, the less protruding apical part of lower central leaves, at least faintly visible glands on central leaves, acuminate (not acute) central leaves of primary shoots and less distinctly papillose upper part of seed wings.
