Opis:: Like St. John Paul II, Pope Francis identifies particular anthropological errors in his teaching that pose threats to marriage and to the family which it founds. This paper identifies and briefly examines three: the individualism which produces a “throwaway culture,” Pelagianism, and Gnosticism. These errors highlighted by Pope Francis parallel important aspects of the teaching of Saint Augustine of Hippo.
Papież Franciszek ‒ podobnie jak św. Jan Paweł II ‒ identyfikuje w swoim nauczaniu szczególne błędy antropologiczne, które zagrażają małżeństwu i opartej na nim rodzinie. Artykuł ten wyróżnia i krótko analizuje trzy: indywidualizm, który tworzy „kulturę odrzucenia”, pelagianizm i gnostycyzm. Te błędy, na które zwraca uwagę papież Franciszek, odpowiadają ważnym aspektom nauczania św. Augustyna z Hippony.

Opis:: The objective of this study was to determine the influence of 20-year sprinkler irrigation of permanent grassland with potato starch and brewery wastewater on the botanical composition of sward, and the yield and nutritional value of hay. The experiment was carried out in Kupiski-Jednaczewo, near Łomża, NE Poland (approximately 600 ha). Potato starch and brewery effluents were mixed at a ratio of 1:0.4. Wastewater was applied in autumn and after the first harvest, at an annual dose of 200-300 mm. The analyzed wastewater contained on average (mg dm-3): N – 223, P – 48, K – 285, Ca – 80, Mg – 46 and Na – 68. The floristic composition of meadow sward was determined before the first harvest in 1998, 2003, 2008, 2013 and 2018, while the yield was determined on trial plots. Five major floristic types of grassland communities were identified based on the percentage of dominant species (above 20% share of the sward). Herbage samples were collected for botanical-gravimetric and chemical analyses. Soil samples were collected in 1991 and 2018. Chemical analyses of soil and plant material were performed by standard methods. The following floristic types of grassland communities developed: Alopecurus pratensis (Ap), Arrhenatherum elatius (Ae), Dactylis glomerata + Festuca rubra (Dg+Fr), and Poa pratensis + Dactylis glomerata (Pp+Dg), Phalaris arundinacea + Glyceria maxima (Pha+Gm), and the Festuca rubra + Anthoxanthum odoratum (Fr+Ao) community in the control treatment (non-irrigated grassland). The content of P, K, Fe, Cu, Mn and Zn increased, whereas the content of Ca, Mg and Na, and pH levels decreased in the analyzed soils. Regardless of the floristic type of sward, the yield of grassland irrigated with wastewater was significantly (1.6 to 2.8-fold) higher than the yield of non-irrigated grassland. Hay harvested from wastewater-irrigated meadows met the nutrient requirements of animals in terms of crude fiber, ash and fat, excluding total protein.

Tematy:: meadow irrigation with wastewater

nutritional value of hay
Opis:: The aim of this study was to determine the effect of 20-year-long irrigation of permanent grasslands with potato starch and brewery wastewater on the botanical composition of sward, yield and nutritional value of hay. The experiment was conducted in the center for wastewater treatment and use in Mątwica-Kupiski (668 ha), which has been equipped with facilities for flood irrigation with wastewater since 1965. Potato starch and brewery effluents were mixed in a storage reservoir at a ratio of 1:0.4. Meadow sward was irrigated with wastewater in autumn and after the first harvest, at an annual dose of 200 – 300 mm. On average, wastewater contained (mg dm-3): N – 223, P – 48, K – 285, Ca – 80, Mg – 46, Na – 68. Before the first harvest in 1998, 2003, 2008, 2013 and 2018, the floristic composition of meadow sward was determined on an 11-degree scale by the Klapp method. Yield was determined in trial plots. Based on the percentage of dominant species (above 20% share of the sward), several floristic types of grassland communities were identified. Herbage samples were collected for detailed botanical and chemical analyses according to the floristic composition of the identified grassland communities. Chemical analyses of plant material were performed by standard methods. Longterm irrigation of meadow sward with wastewater contributed to the development of agronomically important plant communities, except for the Agropyron repens community in the western part of the research site. The yield of grassland irrigated with wastewater, regardless of a floristic type, was 2- to 3-fold higher than the yield of non-irrigated grassland. Hay harveste in wastewater-irrigated meadows met the crude fiber, ash and fat requirements of animals. The total protein content of hay remained within the recommended limits for high-quality fodder, except for the Alopecurus pratensis + Agropyron repens community.

Opis:: We investigate the variability of one of the most often used complexity measures in the analysis of the time series of RR intervals, i.e. Sample Entropy. The analysis is carried out for a dense matrix of possible r thresholds in 79 24h recordings, for segments consisting of 5000 consecutive beats, randomly selected from the whole recording. It is repeated for the same recordings in random order. This study is made possible by the novel NCM algorithm which is many orders of magnitude faster than the alternative approaches. We find that the bootstrapped standard errors for Sample entropy are large for RR intervals in physiological order compared to the standard errors for shuffled data which correspond to the maximum available entropy. This result indicates that Sample Entropy varies widely over the circadian period. This paper is purely methodological and no physiological interpretations are attempted.

Opis:: The triel bonds are analyzed and compared with the hydrogen bond interaction. The triel bonds belong to the class of interactions that are named as the σ-hole and π-hole bonds. The σ-hole bond is an interaction between the σ-hole characterized by the positive electrostatic potential and the electron rich regions such as lone electron pairs, π-electron systems, in other words, centers paying a role of Lewis bases. The σ-holes may be observed for elements of the 14–18 groups of the periodic system and the corresponding interactions with Lewis bases are named; tetrel, pnicogen, chalcogen, halogen and aerogen bonds, respectively. On the other hand, π-holes also characterized by the positive electrostatic potential are observed for centers in planar molecules or planar fragments of molecules in regions above those planes. π-holes may be attributed to triel centers (13th group of the periodic system). The boron and aluminium trihydrides and trihalides are examples of molecules where triels are characterized by π-holes. The mechanism of the triel bond formation is very similar to the mechanism of the formation of the hydrogen bond. It is the Lewis acid – Lewis base interaction where the electron charge transfer from the base unit to the acid one is observed. Next there is outflow of the electron charge from the triel center to the other parts of the Lewis acid unit; in other words the positive charge of the triel center increases as a result of complexation. The triel bonds are often very strong and often they possess characteristics of typical covalent bonds; this is confirmed by the QTAIM (Quantum Theory of Atoms in Molecules) and NBO (Natural Bond Orbital) approaches. For example, for the triel bonds the bond paths between the triel center and the Lewis base center are observed with the bond critical points (BCPs) attributed to those paths. Similarly for the A-H…B hydrogen bonds the H…B bond paths are observed. The parameters of those BCPs often indicate the covalent character of the triel bonds and analogously those characteristics for H-bonds may also indicate the covalent character of the latter interactions. It is very interesting that the triel bonds are observed experimentally in the real systems; for example in crystal structures. The triel center which is trivalent and possesses the trigonal configuration is hypovalent; it means that the octet rule is not obeyed here because of the valence electrons´ deficiency (the triel center possesses six valence electrons in such species). Thus it may interact with one Lewis base ligand reaching rather stable octet and tetrahedral configuration. If the trivalent triel center interacts with two Lewis base ligands thus it may lead to the configuration of the trigonal bipyramid with the hypervalent and pentavalent triel center. These kinds of the triel species occur in crystal structures that are described here.

Opis:: Full-text indexing aims at building a data structure over a given text capable of efficiently finding arbitrary text patterns, and possibly requiring little space. We propose two suffix array inspired full-text indexes. One, called SA-hash, augments the suffix array with a hash table to speed up pattern searches due to significantly narrowed search interval before the binary search phase. The other, called FBCSA, is a compact data structure, similar to Mäkinen’s compact suffix array (MakCSA), but working on fixed size blocks. Experiments on the widely used Pizza & Chili datasets show that SA-hash is about 2–3 times faster in pattern searches (counts) than the standard suffix array, for the price of requiring 0.2n–1.1n bytes of extra space, where n is the text length. FBCSA, in one of the presented variants, reduces the suffix array size by a factor of about 1.5–2, while it gets close in search times, winning in speed with its competitors known from the literature, MakCSA and LCSA.

Opis:: Green fodder plays a key role in nutrition of ruminants, and its quality is determined by the species composition of meadow and pasture swards. Legumes and herbs are generally more abundant in nutrients, especially minerals, than grasses. Calcium (Ca) and phosphorus (P) are particularly important for animal health. The dietary levels of Ca and P should be balanced to increase their availability and utilization. The aim of this study was to determine the content of calcium and phosphorus and the Ca:P ratio in selected legume and herb species from extensively used grasslands in the Olsztyn Lakeland. The study covered the following species of leguminous plants: Trifolium pratense, Trifolium repens, Lotus corniculatus, Lathyrus pratensis, Lotus uliginosus and Vicia cracc, and herbaceous plants: Taraxacum officinale, Achillea millefolium, Plantago lanceolata, Alchemilla vulgaris, Heracleum sibiricum and Cirsium oleraceum. The investigated legumes and herbs differed significantly in their Ca and P content and the Ca: P ratio. All the species were abundant in Ca, and two taxa: Cirsium oleraceum and Heracleum sibiricum, were characterized by particularly high levels of calcium. The highest levels of phosphorus were noted in Heracleum sibiricum, whereas the lowest content of P was determined in Alchemilla vulgaris, Cirsium oleraceum and Trifolium pratense. Cirsium oleraceum was abundant in Ca and deficient in P, hence it was distinguished by the widest Ca:P ratio. Legumes and herbs are valuable components of meadow sward and a rich source of minerals, in particular Ca, in animal diets.

Opis:: Integrated bio- and magnetostratigraphic data from the Lower to Upper Berriasian of the pelagic succession at Barlya (Western Balkan, Bulgaria) are presented. The investigated interval, 24 m thick, covers the top of the Calpionella elliptica, Calpionellopsis simplex and Calpionellopsis oblonga subzones. Magnetozones from the upper part of M17r up to M16n were identified. The boundary between the Elliptica and Simplex subzones correlates with the lower part of M16r, while the boundary between the Simplex and Oblonga subzones is situated in the lower part of M16n. The magnetic susceptibility reveals an increasing trend from the middle part of M16r which accounts for the increasing supply of fine clastic sediments to the basin.

Opis:: The use of hybrid machining methods for parts and devices production become more and more attractive nowadays. The paper presents results of modelling use of DPSS (Diode Pumped Solid State) pulse laser for intensification of electrochemical processes in machine part production. Application of DPSS pulse laser enables possibility to reach high level of localization in both machining and growth processes. Laser beam energy accelerates electrochemical processing, improves process localization and prevents other than the machined surface passivation. These conditions should improve electrochemical micro part precision of manufacturing by means of shape and dimensional accuracy in both machining and growth ECM processing.

Opis:: .Measurements of single-kernel mass and volume made on healthy (control) and scab-damaged samples of grain of three winter wheat varieties never resulted in lower values of mean single-kernel density for scab-damaged grain. This finding, contrary to common opinion, can be explained as being a result of the comparable magnitude of relative decrease (due to infestation) of two features (mass and volume) that define single-kernel density. The discrepancy between results presented in this paper (kernel volume was determined with an air pycnometer) and the results in some other reports (liquid pycnometers used) can result from the different methods applied for kernel volume measurements: when a liquid medium is used the surface tension effect tends to overestimate the volume, especially for scabby kernels that are known to be shrivelled ie possessing voids and pores at the surface that the liquid cannot penetrate. As a consequence kernel density of scabby kernels can be significantly underestimated.

Opis:: Określono prędkość krytyczną unoszenia, grubość, szerokość, długość, kąt tarcia ślizgowego i masę nasion świerka pospolitego z 3 jego partii oraz wyznaczono dla nich współczynniki kształtu, pole przekroju poprzecznego, objętość i gęstość. Następnie nasiona te poddano kiełkowaniu, a proces ten scharakteryzowano zdolnością kiełkowania. Porównano te cechy między sobą wykorzystując analizę wariancji z klasyfikacją pojedynczą oraz analizę korelacji. Zauważono, że ze wskaźnikiem czasu kiełkowania nasion, zarówno tych krótkookresowo, jak i długookresowo przechowywanych, najbardziej jest związana ich prędkość krytyczna unoszenia i masa. Aby uzyskać wyższą zdolność kiełkowania z materiału nasiennego należy wydzielić nasiona najlżejsze, a dla uzyskania większej równomierności wschodów wysiewanych nasion – przeprowadzić sortowanie za pomocą rozdzielaczy pneumatycznych lub wibracyjnych.
The critical transport velocity, thickness, width, length, the angle of sliding friction, weight, shape factors, cross-sectional area, volume and density of Norway spruce seeds from three seed batches were determined. The germination capacity of seeds was also estimated. The examined attributes were compared by a single classifica-tion analysis of variance and a correlation analysis. In both short-term and long-term stored seeds, the highest correlation was observed between germination time and the critical transport velocity and weight of seeds. In order to increase germination capacity, the lightest seeds should be separated from the seed material, and to promote even sprouting – the seeds should be sorted using pneumatic and vibrating separators.

Opis:: Critical transport velocity, the thickness, width, length and the angle of sliding friction of Scots pine seeds harvested from three seed banks (conservation seed stand, commercial seed stand and seed plantation) were determined. The investigated attributes were compared by single classification analysis of variance, correlation, single-variable and multivariate regression analysis. The analyzed seed traits differed significantly between the specimens from the examined seed banks. The equations describing the correlations between the studied attributes were characterized by relatively low percentages of explained variation, which renders them unfit for designing seed and separation models.
Wyznaczono prędkość krytyczną unoszenia, grubość, szerokość, długość i kąt tarcia ślizgowego nasion sosny zwyczajnej, zebranych z trzech odmiennych baz nasiennych (wyłączony drzewostan nasienny, gospodarczy drzewostan nasienny i plantacja nasienna). Porównywano te cechy, wykorzystując analizę wariancji z klasyfikacją pojedynczą, korelację oraz regresję jednej zmiennej i wielu zmiennych. Stwierdzono, że w większości przypadków analizowane cechy nasion z odmiennych baz nasiennych różnią się statystycznie. Równania współzależności między określanymi cechami charakteryzują się stosunkowo niskim procentem wyjaśnionej zmienności, co właściwie wyklucza ich zastosowanie do budowania modeli nasion i procesów rozdzielczych.
