Chemical composition and microencapsulation suitability of sumac (Rhus coriaria L.) fruit extract

2021

Sumac (Rhus coriaria L.), a spice obtained by grinding whole sumac berries, is a complex natural product with a plethora of biological activities that can be favorably explored in nutraceutical and pharmaceutical fields. Sicilian sumac is herein chemically investigated by means of a combined NMR/HR MS-based profiling. A hydroalcoholic extract was prepared and its complexity unraveled following fractionation in an alcoholic and an aqueous fraction. The 1H-NMR spectrum of this latter fraction was dominated by the signals of gallic acid and its derivatives, whereas HR MS and HR MS/MS analyses highlighted the diversity in malic acid derivatives. Gallotannins and galloyl flavonol glycosides with…

Nevardarbīgās pretošanās izpausmes 21. gadsimta revolūciju gaitā

2015

Maģistra darba nosaukums ir „Nevardarbīgās pretošanās izpausmes 21.gadsimta revolūciju gaitā”. Darbā tika pētītas krāsainās revolūcijas Gruzijā, Ukrainā, Baltkrievijā un Krievijā. Gruzijā un Ukrainā krāsainās revolūcijas bijušas veiksmīgas, proti, tika gāzti pastāvošie režīmi, toties Baltkrievijā un Krievijā mēģinājumi gāzt pastāvošos režīmus cieta neveiksmi. Krāsainās revolūcijas ir fenomens, kas vēl nav pilnībā izpētīts, tomēr tām ir iezīmes, kas to atšķir no revolūcijām to klasiskajā izpratnē. Pirmkārt, tas ir nevardarbīgo pretošanās metožu pielietojums. Otrkārt, krāsainās revolūcijas bieži vien ir saistītas ar vēlēšanu procesu, proti, negodīgas vēlēšanas kļūst par sabiedrības masas mobi…

Bermudagrass adaptation in the Mediterranean climate: phenotypic traits of 44 accessions

2014

The use of bermudagrass in the Mediterranean area is increasing for its outstanding tolerance to heat and drought, and its aggressive growth and high recuperative potential make it particularly suited to heavily worn areas and appreciated for sports turfs. However, the overall performance of a given genetic type can be affected by the adaptation to a specific environment. The objective of this research was to determine the variability of a number of phenotypic traits that can affect bermudagrass turf performance on a wide range of bermudagrass accessions grown in two locations in Italy. In May 2010, 44 accessions of bermudagrasses, grouped in “wild”, “improved” “hybrid” and “dwarf” types we…

Biało-czarny świat Ervina Goja

2011

The author takes up the language Ervin Goj’s poetry, a regional lachian poet who has written his poems between the years 1931-1977 under the pen name Óndra Łyhorsky. She analyses the meaning of two colours, namely white and black, which in the European culture symbolize the opposition light – dark, good – bad: white symbolizes innocence, truth, purity, simplicity, honesty, while black symbolizes evil, falsehood, nothingness, mourning, atonement. It is associated with everyday human experience which is reflected in the language and is connected with the following patternsprototypes: white – day (bílý den), black – night (černá noc), for example: bílá holubice, bílé světlo, bílá vrána, černé …

Enhancing the user authentication process with colour memory cues

2022

The authentication process is the first line of defence against potential impostors, and therefore is an important concern when protecting personal and organisational data. Although there are many options to authenticate digital users, passwords remain the most common authentication mechanism. However, with password numbers increasing, many users struggle with remembering multiple passwords, which affects their security behaviour. Previous researchers and practitioners have attempted to suggest ways to improve password memorability and security simultaneously. We introduce novel approach that utilises colour as a memory cue to increase password memorability and security. A longitudinal stud…

Improved camouflage through ontogenetic colour change confers reduced detection risk in shore crabs

2019

Abstract Animals from many taxa, from snakes and crabs to caterpillars and lobsters, change appearance with age, but the reasons why this occurs are rarely tested.We show the importance that ontogenetic changes in coloration have on the camouflage of the green shore crabs (Carcinus maenas), known for their remarkable phenotypic variation and plasticity in colour and pattern.In controlled conditions, we reared juvenile crabs of two shades, pale or dark, on two background types simulating different habitats for 10 weeks.In contrast to expectations for reversible colour change, crabs did not tune their background match to specific microhabitats, but instead, and regardless of treatment, all de…

An evaluation of cool season turfgrassess in order to identify the species and varieties most suitable for the Mediterranean environment

2004

The cultivars of cool season Graminae species diffusely used to establish turfgrasses, are grown in northern areas of Europe. The aim of the research described in this paper was to identify the turfgrass species and cultivars most suitable for the Mediterranean environment. The trial was carried out in 1999 and 2000 at the experimental farm “Parco d’Orleans” belonging to the Department A.C.E.P. of University of Palermo. During the trial sixty different cultivars of cool season turf species were compared – 20 cultivars of Festuca arundinacea Schreb., 20 cultivars of Poa pratensis L., and 20 cultivars of Lulium perenne L. The main biometric and qualitative parameters examined were ground cove…
