Opis:
The paper reports on the occurrence of the epibenthic amphipod Dyopedos monacanthus (Metzger, 1875) in the Baltic Sea. This species belongs to the family Dulichiidae and is found in the North Atlantic and European coastal waters from northern Norway to the English Channel and the Danish Straits. Some 50 years ago, only a few individuals of D. monacanthus were occasionally sighted in the western Baltic (the Arkona and Bornholm Basins). In summer 2006, unusual amphipod specimens were noticed at five deep-water stations over the Słupsk Furrow. This was the first time that D. monacanthus was observed in that area, which is currently the easternmost limit of the species’ range in the Baltic Sea.

Opis:
Chlorogenic acids (CQAs), the esters of caffeic acid and quinic acid, are biologically important phenolic compounds present in many plant species. Nowadays much is known from their pro-health properties, including anti-cancer activity. Yet, the supposition that they may be helpful in fighting obesity and modify glucose-6-phosphatase involved in glucose metabolism have led to a revival of research on CQAs properties and their natural occurrence. Much attention is also paid to the proper analysis of CQAs content in plants and plant products due to the fact that the main CQAs representative in nature i.e. 5-O-caffeoylquinic acid (5-CQA) is commonly employed as a quality marker in the control of various natural products.The common procedures used so far for CQAs determination in plants involve conventional long lasting solvent extraction realized at higher temperatures prior to chromatographic analysis. The drawbacks associated to the conventional extraction techniques have led to the search for new alternative extraction processes that additionally could improve extracts quality. The latter is particularly important as regards CQAs applications, and the fact that these compounds easily transform/degrade to others. According to reports, the conventional heating of 5-CQA in the presence of water causes its isomerization and transformation. The reports prove that 5-CQA not only isomerizes to 3- and 4-O-caffeoylquinic acid, but also undergoes other transformations such as esterification and reactions with water. Hence, in the attempt to improve the process of chlorogenic acids extraction and to make it more effective and environmentally friendly, innovative so-called "enhanced" techniques of extraction have been recently developed and applied. To guarantee the proper analysis of compounds with very similar properties forming the chlorogenic acids family and their numerous transformation/degradation products, hyphenated techniques, in particular LC-MS, are currently being used.

Aspects of gestural alignment in task-oriented dialoguesInterlocutors in a conversation influence each other in a number of dimensions. This process may lead to observable changes in their communicative behaviour. The directions and profiles of these changes are often correlated with the quality of interaction and may predict its success. In the present study, the gestural component of communication is scrutinised for changes that may reflect the process of alignment. Two types of task-oriented dialogues between teenagers are recorded and annotated for gestures and their features. We hypothesize that the dialogue task type (collaborative vs. competitive), as well as certain culture-specific properties of alignment that differ between German and Polish pairs, may significantly influence the process of communication. In order to explore the data and detect tendencies in gestural behaviour, automatised annotation mining and statistical exploration have been used, including a moving frame approach aimed at the investigation of co-occurring strokes as well as re-occurring strokes and their features. Significant differences between German and Polish speakers, as well as between the two dialogue types, have been found in the number of gestures, stroke duration and amplitude. Aspekty wzajemnego dopasowania gestykulacji w dialogach zadaniowychUczestnicy konwersacji wpływają na siebie wzajemnie w wielu różnych wymiarach. Proces ten może prowadzić do obserwowalnych zmian w ich zachowaniach komunikacyjnych. Kierunek i charakter tych zmian często wiążą się z jakością interakcji i mogą pozwolić przewidzieć jej sukces. Celem niniejszego badania jest eksploracja gestowego składnika komunikacji pod kątem zjawisk, które mogą odzwierciedlać zjawisko wzajemnego dopasowania uczestników. Zarejestrowano dwa typy dialogów zadaniowych z udziałem nastolatków. Nagrania anotowano pod kątem gestów i ich cech. W badaniu postawiono hipotezę, iż typ zadania dialogowego (ukierunkowane na współpracę vs. na konkurencję), jak również pewne specyficzne cechy kulturowe dopasowania komunikacyjnego, które różnicują polskie i niemieckie pary rozmówców, mogą oddziaływać na proces komunikacji. W celu eksploracji danych oraz wykrycia tendencji cechujących zachowania gestowe, wykorzystano zautomatyzowane metody analizy anotacji oraz techniki statystyczne. Uwzględniono podejście oparte na ruchomych oknach czasowych, umożliwiające analizę współwystępowania jak i powtarzania gestów właściwych i ich właściwości. Wykazano istotne różnice między rozmówcami polskimi i niemieckimi oraz między typami zadań dialogowych w zakresie liczby gestów, czasu trwania oraz amplitudy gestu właściwego.

Opis:
Background and objectives: Disability is a major public health problem in the developing countries. Yet studies and census reports from developing countries provide insufficient information on disability profiles. Therefore, the aim of this study was to assess occurrence, patterns and socio-demographic correlates of disability in selected rural settings in Nigeria. Materials and methods: This house to house cross-sectional survey was conducted among 200 residents in Moro and Edunabon communities in Ife North Local Government Area, Osun State, Nigeria. Disability was classified according to the World Health Organization International classification with criteria based on functional limitation. Households were considered as the Primary Sampling Unit (PSU) in this study. Descriptive and inferential statistics were used for the analysis of the data obtained. The alpha level was set at p< 0.05. Results: The total occurrence of disability was 16%. Visual disability was the most prevalent (6%) and it was significantly associated with age (χ2=11.702; p= 0.010).  The recorded locomotor, mental, speech and hearing disabilities constituted 5%, 2%, 1% and 2% respectively of the total population surveyed. The overall occurrence was found to be higher among males and the middle-aged group (31-50) and significantly correlated with low socioeconomic status. There was a significant association between visual impairment and age (χ 2=11.702; p= 0.010); hearing disability and marital status (χ2=21.747; p= 0.003); as well as mental disability and marital status (χ2=21.747; p= 0.003). Conclusion: A high occurrence of disability was identified among rural residents in Nigeria, especially among males, those with low socio-economic status, those educated up to secondary school, unemployed and married partners. Visual disability, followed by locomotor disability, is the most common type. It is related to age, while marital status significantly correlates with hearing and mental disability.

Opis:
Due to recent climate changes and monsoon variability, the amount, pattern, and intensity of rainfall are significantly changing in many Asian countries. This paper attempts to study the annual and seasonal rainfall patterns and their variability, and the occurrence of droughts. Monthly rainfall data have been collected from the Department of Meteorology, Colombo, from 1871-2020 for Batticaloa station. The Standard Deviation, Coefficient of Variation least-square trend had computed for annual and seasonal rainfall to study the rainfall variability as whole and different epochs. To study the drought scenario Standardized Precipitation Index had computed, and then the drought was categorized based on the SPI criteria, and the drought severity had distinguished. Spatial rainfall distribution maps had prepared using Arc GIS 10.4 software. The Standard Deviation and the Coefficient of annual rainfall variation are 423.9 and 24.8%, respectively. The epochal variability results reveal that the variability of rainfall is higher in 1961-1990 (CV: 28.9%), which indicates the low dependability, while variability is lower in the epochs of 1931-1960 (CV: 17.7%) and 1871-1900 and (19.6%) respectively. The long-term rainfall trend (1871-2020) results reveal the increasing trend and its r2 = 0.0271. However, only the epoch 1961-1990 shows a downward trend with r2 = 0.2398. The rainfall anomaly results reveal the extreme drought had occurred in 1968 and 1889. The severe droughts had occurred in 1998, 1983, 1981, 1980, 1909, and 1890. Out of 150 years of data periods, 25 years had been identified as drought years. The probability of drought occurrence is P = 0.167. Terefore once in five to six years, drought could have occurred.

The occurrence and elements of morphology of P. negriana Thüm. were studied. The fungus cultures were isolated from grapevine canes cultivated in South–East Poland. Grapevine stems from which the cultures of P. negriana were obtained showed symptoms of necrosis and bark crashes. The species of the fungus was identified on the basis of pycnidia and conidia morphology, the character of colonies growth and biochemical features of the studied isolates.
Przebadano cztery losowo wybrane izolaty Phoma negriana z własnej kolekcji kultur tego gatunku. Izolaty wyosobniono w latach 2000-2003 z łozy winorośli odmian Schuyler, Iza i RF-16 z objawami nekrozy i pękania kory. Oznaczano je na pożywkach standardowych: maltozowa (MA), wiśniowa (CA) i owsiana (OA), przy uwzględnieniu aktualnych zasad taksonomii Phoma spp. Opis morfologii kolonii oraz pomiar ich średnicy wykonano po 7 i 14 dniach hodowli. Po 2 tygodniach wzrostu na pożywce OA wykonano pomiar 400 konidiów, 200 piknidiów oraz sprawdzono obecność chlamydospor. Uzyskane wyniki upoważniły do uznania badanego gatunku jako Phoma negriana Thüm., sekcja Phoma. Makroskopowe cechy kolonii badanych izolatów, zwłaszcza tempo i charakter wzrostu, zabarwienie i struktura grzybni powinny mieć istotne znaczenie przy identyfikacji gatunków z rodzaju Phoma. Ze względu na duże podobieństwo morfologiczne zarodników Phoma spp., ich wymiary należałoby traktować jako ważną, aczkolwiek pomocniczą cechę diagnostyczną. Uzyskane wyniki potwierdziły niespecyficzny charakter reakcji izolatów P. negriana z 1 N NaOH. W Polsce badany gatunek nie był dotychczas notowany.

Also seed germination and contamination by other fungi were considered. Surface sterilized seeds were plated on Coon agar medium. A sample contains 50 seeds. Data were taken after 8 days of incubation. Frequency of species occurrence depended not only on characters of genotypes, weather conditions during 1998-2001, but on inoculation treatment. Clear response between genotypes to tested factors was noted. Seeds of normal leaved line 344/87/3 and cv. Rubin were the most inhabited by all fungi, and germinated very poorly. Seeds of eight genotypes, including cvs: Kwestor, Agra, Miko, were less infected and better germinated...

Prostaglandins have also been found in very primitive organisms as bacteria, varions plants and protozoa. We summarise that prostaglandins seem to be a very ancient group, going back to the roots of evolution. They are as universal in cell physiology as DNA in genetics. In host-parasiter eicosanoids also parasitic origin, play an important role as a modulators of hosts immune responsiveness.

In this review we provide an evaluation of the Festschrift honoring the occasion of Prof. Witold Mańczak’s ninetieth birthday. We start by sketching general characteristics of the book, emphasizing the wide range of tributary topics covered, as well as the range of languages of contributions, reflecting the many areas where the Professor’s work impacted the language sciences. Then we focus on one of the most controversial claims advocated by the Festschrifee, which has spawned a lot research and findings, namely, the importance of the frequency of occurrence of a given linguistic item. We argue that this claim should be considered against the wider background of the Natural Linguistics paradigm. Finally, we review and synopsize the content, which we proposed to group into the following thematic realms: (i) Etymology / language contact; (ii) Language change, theory and history of language; (iii) Syntax/semantics; (iv) Contemporary language usage / sociolinguistics; (v) Lexicography / translation studies. The article ends with the general recommendation of the monograph to a broad readership.

Opis:
The Atriplex littoralis L. is a rare and endangered species in Poland and many other countries in Europe. In Poland it is mainly found on the west coast and also rarely in central parts. It has been seen in Puck Bay and the Gulf of Gdańsk as well as in Hel Peninsula. The grassleaf orache is a halophyte, terophyte and a sunlight-loving plant. Data shows that apart from on the coast, this species may also appear in inland areas, for example on ruderal habitats such as roadsides. The results of our observations confirm the presence of the species on beaches and rocky bank reinforcement, with accumulation of annual vegetation in the Hel Peninsula and Puck Bay. Five sites, where Atriplex littoralis specimens occur have been found. In each site 1 to 15 specimens where found, in total 31. Five phytosociological relevés were made within the floristically poor patches of Matricario maritimae-Atriplicetum littoralis (Christiansen 1933) R.Tx. 1950. This association represents the protected type of habitat: Annual vegetation of drift lines (1210).
