Opis:
Most of the basic control methods of the grid-connected converter (GCC) are defined to work with a sine wave grid voltage. In that case if the grid voltage is distorted by higher harmonics, the grid current may be distorted too, which, in consequence, may increase the value of the THD of the grid voltage. The paper deals with an improved finite control set model predictive control (FCS-MPC) method of an LCL-filtered GCC operating under distorted grid conditions. The proposed method utilizes supplementary grid current feedback to calculate the reference converter current. The introduced signal allows to effectively improve the operation when the grid is subject to harmonic distortion. The paper shows a simulation analysis of the proposed control scheme operating with and without additional feedback under grid distortions. To validate the practical feasibility of the proposed method an algorithm was implemented on a 32-bit microcontroller STM32F7 with a floating point unit to control a 10 kW GCC. The laboratory test setup provided experimental results showing properties of the introduced control scheme.

Opis:
Nowadays, the increasing number of non-linear loads influences the grid, causing grid voltage disturbances. These disturbances may be very dangerous for the equipment and can create faults in converter behaviour. However, the right control algorithm can improve the reliability of the work. For a current source rectifier, the finite control set model predictive control has been proposed. This method is very flexible because of the variety of the possible cost function forms. It has been examined under grid voltage disturbed by the higher harmonics and the voltage drop. Simulation results prove the ability to damp the distortions and to ensure the unity power factor. Summing up, the algorithm is a very good solution for use in applications such as battery charging, active power filtering and low-voltage direct current load feeding.

Opis:
The study aimed at determining changes in the contents of selected metals in the biomass of test plants due to fertilisation with fresh and composted sewage sludge, hard coal ash, and sludge-ash mixture, as well as liming at a background of mineral nutrition. The experimental design was a completely randomised arrangement with three replicates. The following factors were examined: fertilisation with organic and mineral materials (fresh sewage sludge; composted sewage sludge; hard coal ash; calcium carbonate) and mineral fertilisation (no fertilisation; NPK fertilisation). An application of sewage sludge, hard coal ash, and sludge-ash mixture significantly increased maize content of barium. Addition of hard coal ash into sewage sludge contributed to an increase in lead content determined in cocksfoot biomass harvested from the first and second cut, and barium in maize biomass. Soil liming significantly affected barium content the biomass of plants harvested from the first and second cut, as well as in maize biomass. NPK nutrition significantly increased barium concentrations in the biomass of test plants and maize.

Opis:
One of the actual challenges in tissue engineering applications is to efficiently produce as high of number of cells as it is only possible, in the shortest time. In static cultures, the production of animal cell biomass in integrated forms (i.e. aggregates, inoculated scaffolds) is limited due to inefficient diffusion of culture medium components observed in such non-mixed culture systems, especially in the case of cell-inoculated fiber-based dense 3D scaffolds, inside which the intensification of mass transfer is particularly important. The applicability of a prototyped, small-scale, continuously wave-induced agitated system for intensification of anchorage-dependent CP5 chondrocytes proliferation outside and inside three-dimensional poly(lactic acid) (PLA) scaffolds has been discussed. Fibrous PLA-based constructs have been inoculated with CP5 cells and then maintained in two independent incubation systems: (i) non-agitated conditions and (ii) culture with wave-induced agitation. Significantly higher values of the volumetric glucose consumption rate have been noted for the system with the wave-induced agitation. The advantage of the presented wave-induced agitation culture system has been confirmed by lower activity of lactate dehydrogenase (LDH) released from the cells in the samples of culture medium harvested from the agitated cultures, in contrast to rather high values of LDH activity measured for static conditions. Results of the proceeded experiments and their analysis clearly exhibited the feasibility of the culture system supported with continuously wave-induced agitation for robust proliferation of the CP5 chondrocytes on PLA-based structures. Aside from the practicability of the prototyped system, we believe that it could also be applied as a standard method offering advantages for all types of the daily routine laboratory-scale animal cell cultures utilizing various fiber-based biomaterials, with the use of only regular laboratory devices.

Celem pracy było określenie wpływu rodzaju przegród na warunki wytwarzania zawiesiny w mieszalniku z mieszadłem. Analizę przeprowadzono w oparciu o wyznaczone doświadczalnie wartości krytyczne częstości obrotów mieszadła nkr oraz odpowiadające im wartości liczby Frouda Frkr i jednostkowej mocy ekn w mieszalniku ze standardowymi przegrodami płaskimi lub pionowymi przegrodami rurowymi. Pomiary wykonano w zbiorniku o średnicy D = 0,634 m i objętości roboczej VL = 0,2 m3. Do wytworzenia zawiesiny o różnym stężeniu cząstek ciała stałego, zastosowano mieszadło turbinowe Rushtona lub A 315. Analiza otrzymanych wyników pozwoliła stwierdzić, że przegrody rurowe mogą stanowić pewną alternatywę dla przegród płaskich przy wytwarzaniu zawiesiny w mieszalniku mechanicznym.
The aim of this study was to determine the effect of baffle type on the conditions of suspension production in the agitated vessel. The analysis was carried out on the basis of experimentally obtained critical impeller speed values nkr , adequate Froude number Frkr and mean energy dissipated values ekr in a vessel with standard flat or vertical tubular baffles. Measurements were conducted in the agitated vessel of inner diameter D = 0.634 m, and working liquid volume VL = 0.2 m3. The suspension with various concentrations was agitated by Rushton turbine or A315 impeller. The analysis of results revealed that tubular baffles may be an alternative to flat baffles in case of suspension production in the agitated vessel

Opis:
Seaweed extracts have been recently introduced to crop growing, particularly to sustainable agriculture, in many countries worldwide. However, our knowledge of the action produced by Kelpak is only fragmentary as it is influenced by a number of factors, for example crop plant species and extract application schedule. Our objective was to determine the effect of Kelpak SL on the content of selected microelements in two grass species. A field experiment was arranged in a randomized subblock design (split-split-plot) with three replicates. It was conducted at the Experimental Unit of the University of Natural Sciences and Humanities in Siedlce (Poland) and started in late April each year. The following factors were examined: pure stands of two grass species Dactylis glomerata L. (cv. Amila) and Festulolium braunii (K.Richt.) A. Camus (cv. Felopa) grown in a monoculture, a biostimulant distributed under the trade name Kelpak SL, applied at 2 dm3 ha-1 (no biostimulant in the control treatment), and nitrogen applied at 50, 100, 150 kg ha-1 (no nitrogen in the control). During the experiment, grass was cut three times a year. The plant material was subjected to chemical analyses to assess dry matter (by determining the moisture content), zinc, copper, iron and manganese. The application of Kelpak significantly increased the Zn, Cu, Fe and Mn content in the grass species tested, regardless of the remaining factors. The grass species did not differ significantly in their content of Zn, Cu, Fe and Mn. The concentrations of the microelements in both species were significantly affected by a dose of nitrogen. At higher nitrogen doses, the concentrations of Zn, Cu and Fe were lower, unlike the content of Mn, which increased. The Fe:Mn ratio in the dry matter of both grasses was 2.79, which indicates some manganese deficiency.

Opis:
Holsteinian fluvial deposits in the Samica River valley in eastern Poland have been studied, in an approximately 12-m-thick succession filling palaeochannels and comprising sandy channel facies succeeded by a package of gyttja, peat and silt deposited in oxbow. Channel belts including palaeochannel fills cut into outwash sands and are overlain by diamictic sands reworked by solifluction under periglacial conditions. Sedimentological and palynological investigations in combination allowed the recognition of glacial and interglacial deposits. The channel belt was formed by a typical sand-bed, meandering river with deposition controlled by abundant point bars. The sedimentary evolution of the Samica valley is interpreted in the context of the glacial-interglacial cycle. Valley-scale erosion and change of river style from braided to meandering occurred coevally with the decay of an ice sheet (deglaciation) and the main phase of meandering river sedimentation is attributed to latest Elsterian and early Holsteinian. The next part of the interglacial, from pioneer stage to established temperate conditions, is recorded in a biogenic oxbow-lake fill. The succession studied has been compared with published data on the European fluvial deposits of Middle Pleistocene interglacials. It is pointed out here that river channel patterns in western and eastern Europe differed. Based on this observation, some general hypotheses regarding the continental-scale climatic distinctness are put forward.

The research was undertaken to determine the effect of the biostimulant Kelpak SL, derived from brown seaweed species Ecklonia maxima (kelp), on structural and non-structural carbohydrates, as well as lignin content in orchard grass and Braun’s festulolium. The experiment was a split-plot arrangement with three replicates. It was set up at the experimental facility of the University of Natural Sciences and Humanities, Siedlce, in late April 2009. The following factors were examined: an application of the plant growth regulator Kelpak SL applied at the rate of 2 dm3·ha-1 vs an untreated control (0 dm3··ha-1), pure sown grass species and cultivars grown in monoculture: Dactylis glomerata, cv. Amila and Tukan, as well as Festulolium braunii cv. Felopa and Agula. This study revealed that an application of Kelpak significantly reduced cellulose, hemicellulose and lignin contents of the grasses but significantly increased non-structural carbohydrates, regardless of the remaining factors. Non-structural carbohydrates were the highest in Kelpak-treated Festulolium braunii (on average, 232.7 g·kg-1).

Opis:
Recent demand for powering small sensors for wireless health monitoring triggered activities in the field of small size efficient energy harvesting devices. We examine energy harvesting in an aluminium beam with a piezoceramic patch subjected to kinematic harmonic excitation and impacts. Due to a mechanical stopper applied, inducing a hardening effect in the spring characteristic of the beam resonator, we observed a broader frequency range for the fairly large power output. Impact nonlinearities caused sensitivity to initial conditions and appearance of multiple solutions. The occurrence of resonant solution associated with impacts increased efficiency of the energy harvesting process.

Opis:
Metals in soils occur in different forms, which are more or less mobile, which means bioavailable. The aim of this study was to assess the content of zinc in cultivated plants, depending on soil properties but also its content in soil and fractions in typical and unpolluted region, which is the Podlasie Province. The research material consisted of samples taken from arable soil in 81 points of Podlasie Province. Basic physicochemical properties and content of soil fraction < 0.02 mm in samples were determined. Pseudo-total content of zinc and its fractional composition in soil as well as zinc content in plants was evaluated. Correlation cśfficients between the content of zinc in plants and physicochemical properties of soil were calculated. It was found that examined soil contained natural amount of zinc, characteristic for uncontaminated soils. The most of zinc was associated with the organic matter fraction and the least with residual fraction. Among the analysed plants from light soils, the most of zinc was found in rye. Plants from medium-heavy soils contained similar amount of zinc, with the exception of maize. Correlation cśfficients do not confirm the significant relationship between soil properties and zinc in plants. Significant relationship was stated between bioaccumulation factors and the content of zinc in plants.
Metale występują w glebie w różnych formach, które są bardziej lub mniej rozpuszczalne, a tym samym w różnym stopniu biodostępne. Celem pracy było określenie zawartości cynku w roślinach uprawnych w województwie podlaskim, w zależności od właściwości gleby oraz jego zawartości w glebie i w poszczególnych frakcjach. Materiał badawczy stanowiły próbki gleb i roślin uprawnych pobrane w 81 punktach woj. podlaskiego. W próbkach oznaczono podstawowe właściwości fizykochemiczne gleby, określono kategorię agronomiczną gleb i podzielono je na dwie grupy: gleby bardzo lekkie i lekkie oraz gleby średnie. Oznaczono zawartość cynku w roślinach oraz zbliżoną do ogólnej jego zawartość w glebie i skład frakcyjny. Obliczono współczynniki korelacji między zawartością cynku w roślinach a właściwościami fizykochemicznymi gleb i frakcjami cynku w glebie oraz jego współczynnikami bioakumulacji. Stwierdzono, że badane gleby zawierały naturalne ilości cynku, charakterystyczne dla gleb niezanieczyszczonych. Zawartość cynku w poszczególnych frakcjach układała się w następujący szereg: frakcja związana z substancją organiczną > frakcja związana z tlenkami i wodorotlenkami > frakcja wymienialna > frakcja rezydualna. Wśród analizowanych roślin uprawianych na glebach lekkich najwięcej cynku zawierało żyto. Rośliny uprawiane na glebach średnich, z wyjątkiem kukurydzy, zawierały zbliżone ilości cynku. Nie stwierdzono istotnych zależności pomiędzy zawartością cynku w roślinach a właściwościami gleb. Istotne zależności wystąpiły tylko w przypadku współczynnika bioakumulacji.

Opis:
Different methods have been used to determine the stratigraphic position of Pleistocene alluvial deposits, particularly fluvial interglacial deposits. Near-surface deposits of a meandering river, developed in point-bar and oxbow lake facies, in the Samica River valley (near Łuków, eastern Poland) have been investigated. The fossil valley is incised into the till plain and the outwash. The fluvial succession is locally overlain by solifluction deposits. All the deposits underwent sedimentological analysis. The petrographic composition of basal till occurring in the vicinity of a fossil valley was determined with the method of indicator erratics. Fluvial deposits were examined by pollen analysis and plant macrofossil analysis of oxbow lake facies. Absolute dating methods were applied to the deposits (thermoluminescence methods: TL and additionally IRSL). Lithological differences between fluvial and the surrounding glaciofluvial deposits were identified and their lithostratigraphic position assigned. Petrographic analysis of till and palaeobotanical analyses of oxbow lake facies gave compatible results. Fluvial deposits were formed after the Sanian 2/Elsterian Glaciation, during the Mazovian/Holsteinian Interglacial. Luminescence dating of the fluvial deposits by the TLMAX method yielded the most relevant results (412-445 ka), which indicate that these deposits were formed during the end of the MIS 12 and beginning of the MIS 11 stage.
