Opis:
The paper deals with the rise of French sequences where two etymologically and functionally divergent markers, an erstwhile reflexive se and the l’un l’autre cluster, combine to encode reciprocity. Unlike in other old Romance languages, in medieval French (12th to 14th centuries) cumulative reciprocal constructions arise relatively late. In the meantime, they rely either on l’un … l’autre (acting as substitutes of verbal arguments) or on se. The only exception involves pronominal verbs of movement that encode symmetric relations. Two independent mechanisms are claimed to have been responsible for broadening the domain of cumulative sequences: the weakening of anaphoric links of l’un … l’autre to their antecedents and subjectification. Since plural subject-verb agreement is obligatory in sentences with reciprocal se-verbs, the singular l’un is unlikely to fill a slot for subject. Therefore, it is coerced into drifting rightwards to form a single syntactic constituent with l’autre. Subjectifi cation circumscribes cases where, notwithstanding the presence of l’un l’autre, se accompanying a verbal plural is sufficient to convey reciprocity. As a consequence, cumulative sequences become widespread in 16th century. All in all, the shift is viewed as an instance of construction becoming increasingly schematic over time.

Opis:
Embryo development of Lupinus albus L. and L. mutabilis Sweet. after pollination with L. angustifolius L. was studied. Observations of ovules revealed non-typical embryo development. From the 5th day after pollination, high number of degenerated ovules was found; the highest number was observed on 15 and 20 days after pollination. The period between the 10th and 15th day after pollination was the most suitable for isolation of embryos in all the examined combinations, with exception L. albus x L. angustifolius where optimal isolation time was between 15th and 20 th day after pollination. Embryos were obtained in each cross-pollination. Some of them developed in vitro into plantlets and grew in an artificial medium for some time, but most of them died due to non-typical development of the root system, stem, or both. The hybrid character of the survived plants requires confirmation.

Opis:
This study deals with populations of the European-South-Siberian geoelement Adenophora liliifolia (L.) A. DC. in the Czech Republic, Slovakia, Hungary, Romania, and Poland, where this species has its European periphery distribution. We studied the population size, genetic variability, site conditions, and vegetation units in which A. liliifolia grows. Recent and historical localities of A. liliifolia were ranked into six vegetation units of both forest and non-forest character. A phytosociological survey showed differences in the species composition among localities. Only a weak pattern of population structure was observed (only 22% of total genetic variation present at the interpopulation level, AMOVA analysis), with moderate values for gene diversity (Hj = 0.141) and polymorphism (P = 27.6%). Neighborjoining and Bayesian clusterings suggest a similar genetic background for most of the populations from Slovakia, the Czech Republic, and Poland, contrary to the populations from Hungary, Romania, as well as two populations from Central and South Slovakia. This might be explained by a relatively recent fragmentation of the A. liliifolia populations in Central Europe. Nevertheless, it seems that several populations in Romania, South Hungary, and Slovakia were isolated for a longer period of time and their genetic differentiation is more evident.

Opis:
We propose a generalization of the Butkovskiy’s method of control with compact support [1] allowing to derive exact controllability conditions and construct explicit solutions in control problems for systems with distributed parameters. The idea is the introduction of a new state function which is supported in considered bounded time interval and coincides with the original one therein. By means of techniques of the distributions theory the problem is reduced to an interpolation problem for Fourier image of unknown function or to corresponding system of integral equalities. Treating it as infinite dimensional problem of moments, its L1, L2 and L-optimal solutions are constructed explicitly. The technique is explained for semilinear wave equation with distributed and boundary controls. Particular cases are discussed.

Opis:
Salinity has adverse effects on plants and is one of the causes of environment degradation. Plants have developed many defensive mechanisms, protecting them from sodium chloride (NaCl), including accumulation of osmoprotective compounds, which maintain osmotic balance, protect cell structure and enzymes. In the current study, we investigated the effects of salinity resulting from a range of sodium chloride concentrations (from 0 to 400 mM) on the growth of common duckweed (Lemna minor L.) and yellow lupin (Lupinus luteus L.). Increasing concentration of sodium chloride decreased the area of common duckweed leaves. At the highest applied salt concentration, the decrease of leaf area was associated with leaf chlorosis. In yellow lupin, the increasing sodium chloride concentration inhibited root and stem elongation. The highest tested NaCl concentration of 400 mM completely stopped elongation of yellow lupin shoots. The content of cyclitols and soluble carbohydrates in plant tissues was evaluated as well. Cyclitols (D -chiro -inositol and D -pinitol), as well as soluble carbohydrates (glucose, fructose and sucrose) were detected in common duckweed tissues. Yellow lupin seedlings also contained cyclitols - D -pinitol, myo -inositol and D -chiro -inositol - and soluble carbohydrates - glucose, galactose and sucrose. The content of osmoprotectants in plant tissues, especially sucrose and cyclitols, increased with increasing concentration of sodium chloride in the soil. The results indicate that the content of cyclitols and soluble carbohydrates in plant tissues can be an indicator of plant response to salinity stress.
Zasolenie wpływa niekorzystnie na roślinność i stanowi jedną z przyczyn degradacji środowiska wodnego i glebowego. Rośliny wykształciły wiele mechanizmów odporności na NaCl, jednym z nich może być akumulacja związków osmoprotekcyjnych, utrzymujących równowagę osmotyczną, chroniących struktury komórkowe i enzymy. W pracy badano wpływ zasolenia wywołanego różnymi stężeniami chlorku sodu (od 0 do 400 mM) na tempo wzrostu rzęsy drobnej (Lemna minor L.) i łubinu żółtego (Lupinus luteus L.). Ponadto w tkankach roślin oceniano zawartość cyklitoli i węglowodanów rozpuszczalnych. Wzrastające stężenie chlorku sodu zmniejszało powierzchnię liści rzęsy drobnej. W najwyższym z zastosowanych stężeń obok redukcji pola powierzchni liści obserwowano również intensywną chlorozę liści. Wzrastające stężenie chlorku sodu hamowało wzrost elongacyjny korzeni i łodyg łubinu żółtego. Najwyższe z badanych stężeń NaCl całkowicie hamowało wzrost elongacyjny łodyg łubinu żółtego. W tkankach rzęsy drobnej występowały cyklitole (D -chiro -inozytol i D -pinitol) oraz węglowodany rozpuszczalne (glukoza, fruktoza i sacharoza). Natomiast w siewkach łubinu żółtego występowały cyklitole (D -pinitol, myo -inozytol i D -chiro -inozytol) oraz węglowodany rozpuszczalne (glukoza, fruktoza, galaktoza i sacharoza). Wykazano, że wraz ze wzrostem stężenia chlorku sodu w podłożu wzrastała zawartość osmoprotektantów (cyklitoli i sacharozy) w tkankach. Badania wykazały, że cyklitole i węglowodany rozpuszczalne obecne w tkankach łubinu żółtego i rzęsy drobnej są dobrymi biomarkerami środowiska zanieczyszczonego chlorkiem sodu.

Opis:
The paper presents experimental and numerical validation of the combustion process of coal and flour dust dispersed in a spherical chamber of 20 cubic decimetres volume. The aim of the study is to validate the numerical simulation results in relation to the experimental data obtained on the test stand. To perform the numerical simulations, a Computational Fluid Dynamics code FLUENT was used. Geometry of the computational domain was built in compliance with EN 14460. Numerical simulations were divided into two main steps. The first one consists in a dust dispersion process, where influence of standardized geometry was verified. The second part of numerical simulations investigated dust explosion characteristics in compliance with EN 14034. After several model modifications, outcomes of the numerical analysis shows positive agreement with both, the explosion characteristics for different dust concentration levels and the maximum pressure increase obtained on the test stand.

Opis:
Scentless chamomile Matricaria maritima (L.) ssp. inodora (L.) Dostal and common poppy Papaver rhoeas (L.) are species which very often infest winter cereal and winter rape crops. Inhibitors of acetolactate synthase (ALS) are commonly used for control of these weeds. The herbicides are characterised by a single site of action in the plant, which has an influence on selection of the weed population and may result in a rapid development of resistance. In 2012, five seed samples of scentless chamomile and five samples of common poppy were collected from five winter wheat crop fields in Żuławy Gdańskie where the weed species were very poorly controlled. Results of greenhouse experiments showed that two biotypes of scentless chamomile and common poppy were resistant to tribenuron methyl. It was not possible to control resistant biotypes even after use of tribenuron methyl at a dose four times higher than recommended in Poland, it is the first reported case of scentless chamomile and common poppy biotypes’ resistance to herbicides. It is not of economic importance but it does prove the growing problem of weed resistance in the country.
