Screening of chemical composition of summer savory essential oils using solid-phase microextraction and GC-MC
Problems related to medicinal, spice (aromatic) plants species diversity, enhancing and improving human health are solved according to the Global Strategy for Plant Conservation and the Convention on Biological Diversity adopted regulations [1, 2]. The aim of this study is to investigate chemical composition of medicinal (aromatic) plant Summer savory. The object – Summer savory (Satureja hortensis L.) – annual herbaceous plant from Lamiaceae Lindl. introduced in Lithuania in Kaunas Botanical Garden of Vytautas Magnus University since 1962 [3, 4]. The raw material of the medicinal plant is herb of Savory (Herba Saturejae). Aerial parts of plant are widely used in traditional medicine for cramps, digestion disorders and inflammations. Savory has antimicrobial, antiviral, antispasmodic, anti-inflammatory, antifungal and antidiarrheal properties related to high concentration of essential oils and polyphenols. The main biological active substances of essential oils are carvacrol, thymol, γ-terpinen, thymoquinone, o-cymene and β-caryophyllene. Phytochemical analysis of medicinal plant was performed using solid-phase microextraction and gas chromatography-mass spectrometry by determining essential oil components of Satureja hortensis L. raw material [5, 6]. The results obtained during qualitative and quantitative evaluation of the raw material essential oil demonstrated that this medicinal (aromatic) plant can be successfully cultivated in Lithuania and used in the pharmaceutical and food industries.Gamtos mokslų fakultetas / Faculty of Natural SciencesBiochemijos katedra / Department of BiochemistryBotanikos sodas / Botanical GardenVytauto Didžiojo universitetas / Vytautas Magnus Universit
Den heliga skriften. Läsrörelsen, Mc Donald's och kulturarvet
2001 meddelade Mc Donald's att de inlett ett unikt samarbete med Läsrörelsen. Under en månads tid skulle hamburgerrestaurangen erbjuda en barnbok av hög kvalitet till alla som köpte ett Happy Meal. Satsningen visade sig vara framgångsrik och har sedan dess upprepats årligen. Läsrörelsen vill fostra duktiga läsare och Mc Donald's duktiga konsumenter. Vad händer när två så olika intressen och diskurser sammanförs

Interactively using Semantic Web knowledge: Creating scalable abstractions with FacetOntology
The amount of knowledge accessible on the Semantic Web is growing, and there is a need for a scalable solution to facilitate exploring that data. Currently approaches to exploring Semantic Web data either focus on exploring resources individually, following links during exploration, and making little use of collated data, or take the approach of collating and aligning multiple sources into one store for one purpose, and hand-crafting a specific browsing interface onto it. We present an approach that provides a scalable browsing interface, which can browse knowledge from the Semantic Web at will. Our approach creates abstractions of knowledge, collated into facets, which are described using FacetOntology. FacetOntology facilitates describing facets from RDF data, suitable for use in creating datasets for faceted browsing
Growth Morphologies and Mechanisms of Non-Equilibrium Solidified MC Carbide
Growth morphologies and mechanisms of the carbide of group IVB and VB elements (MC carbide), a typical faceted crystal, were studied with an estimated cooling rate from 102 to 105 K/s. Results showed that although the growth morphologies of the MC carbide vary remarkably with solidification cooling rate, the solid/liquid interface is always atomically smooth, and the growth mechanisms are always lateral growth. The growth mechanism transition from lateral to continuous growth mode, which was predicted by the classic crystal growth theory, was not observed for the TiC type MC carbide within the estimated cooling rate range of 102?105 K/s
Ruth Klüger: la creatività per non “smarrirsi strada facendo”
R. Klüger, a jewish viennese, a US citizen and a germanist, is the Author of two autobiographies “weiter leben”and “unterwegs versore”. Written in a style which alternates between essay and poetry, account and recollection, they are the occasion for the Author to establish a dialogue with the women having as a focus the exchange of experiences and reflections over the status of the feminine emancipation
Eutectic MC Carbide Growth Morphologies of a Laser Clad TiC/FeAl Composite Coating
In this paper, eutectic MC carbide growth morphology and its evolution with laser scanning speed were studied comprehensively of a laser clad MC carbide reinforced FeAl intermetallic matrix composite coating. As the laser scanning speed increased, the growth morphology of eutectic MC carbide was found to be needle-aligned annulation, butterfly-like and well-developed dendrite
Performance analysis of the MC-CDMA system in frequency selective slow Rayleigh fading channels, DS-CDMA or MC-CDMA?
This report describes the Bit Error Probability (BEP) performance of Multi-Carrier Code Division Multiple Access (MC-CDMA) system using the RAKE-receiver in frequency selective slow Rayleigh fading channels. The analysis has been carried out by a theoretical approach using the characteristic function method for quadratic form of Gaussian random variables and by computer simulation. The BEP performance of Direct Sequence Code Division Multiple Access (DS-CDMA) system under the same conditions is analysed and compared with the BEP performance of the MC-CDMA system.Electrical Engineering, Mathematics and Computer ScienceTelecommunicatie- en Verkeersbegeleidingssysteme
