AB  - Sweet cherry (Prunus avium L.) is one of the most appreciated temperate fruit trees, whose fruits are among the first to ripen in the season. Fruits are used mainly for fresh consumption, and very little for processing. Sweet cherry fruits contain large amounts of soluble solids (10- 22%) most of which are sugars. Glucose and fructose are dominant, while the amount of sucrose is significantly lower. The content of organic acids is relatively low (0.3-1.2%), and malic acid is dominant. Sweet cherries are also a rich source of bioactive compounds, such as polyphenols, vitamins, minerals, and dietary fibers. The most abundant classes of phenolic compounds are anthocyanins, phenolic acids and flavonols, which contribute to antioxidant potential of the fruits. Anthocyanins, which give the fruits their red color, are especially important. Cyanidin-3-rutinoside followed by cyanidin-3-glucoside is the most abundant anthocyanin in sweet cherry fruit. Moreover, neo-chlorogenic acid, chlorogenic acid, and p-coumaroylquinic acid are most represented phenolic acids. High content of bioactive compounds in sweet cherries are mainly responsible for many beneficial health effects: reduced inflammation and symptoms of arthritis, regulation of blood pressure, reduced risk of a stroke, weight loss, prevention of cancer, diabetes and Alzheimer's disease [1]. 
The aim of the present research was to examine chemical composition of nine cherry cultivars varieties: ‛Vega’, ‛Carmen’, ‛Grace Star’, ‛Samba’, ‛Black Star’, ‛Olympus’, ‛Benton’, ‛Sela’, and ‛Staccato’, using Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy. The sweet cherry samples were weighed, and then dissolved in 50:50 ethanol/water (v/v) solutions. Ultrasound-assisted extraction was used to extract the antioxidant compounds. After extraction, the samples were filtered and evaporation was carried out on a vacuum on the 40°C [2]. The cherry extract was recorded in absorbance mode, using a Nicolet™ iS™ 10 ATR-FTIR Spectrometer (Thermo Fisher Scientific). The ATR-FTIR spectra of analyzed samples were recorded in the range 500-4000 cm-1. The obtained absorption maxima indicated presence of esters, monosaccharides, polysaccharides, flavonoids and anthocyanin pigments in studied cherry cultivars varieties. Intensity of specific bands differed between cherry cultivars.

AB  - In this paper, one of the most promising electron devices - carbon nanotube field effect transistor (CNT FET) is investigated. At the beginning, the carbon nanotube properties are presented. The main contribution of this paper is the new analytical model of CNT FET - current voltage characteristics. Developed model describes behavior of CNT FET in very good manner and, at the same time, the model is relatively simple. Using the developed model, simulations were performed. The results obtained by using proposed model are in very good agreement with already known and published ones.
