Essential oil compositions of Teucrium fruticans, T. scordium subsp. scordioides and T. siculum growing in Sicily and Malta
2020
In the present study, the chemical composition of the essential oils from the aerial parts of Teucrium fruticans L. collected in Sicily and Malta, Teucrium scordium subsp. scordioides (Schreb.) Arcang. and Teucrium siculum (Raf.) Guss., collected in Sicily, were evaluated by GC-MS. The main volatile components of both T. fruticans collections were germacrene D (29.4% and 50.0%), (E)-β-caryophyllene (19.6% and 21.9%), and 1-octen-3-ol (19.7% and 7.4%); T. scordium subsp. scordioides essential oil was rich in caryophyllene oxide (25.8%), α-pinene (19.4%) and β-pinene (8.5%); T. siculum essential oil was rich in (E)-β-caryophyllene (30.9%), 1-octen-3-ol (9.0%), α-humulene (8.6%) and germacrene…
Presence of multiple group I introns closely related to bacteria and fungi in plastid 23S rRNAs of lichen-forming Trebouxia
2009
The chloroplast-encoded large subunit ribosomal RNA gene of several free-living green algae contains group I introns at Escherichia coli genic positions 1917, 1931, 1951, and 2449. Herein we report the presence of group I introns at these positions within the chloroplast-encoded large subunit ribosomal RNA gene of several lichen-forming green algae belonging to the Trebouxia genus. In contrast to the introns inserted at position 2449, all introns inserted at positions 1917, 1931, and 1951 contained LAGLIDADG homing endonuclease genes. Phylogenetic analyses show that: (i) introns inserted at positions 1917, 1931, and 1951 are closely related to introns located at homologous insertion sites i…

A real time operating system for embedded platforms
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad SDL (Specification and Description Language) is today widely used for description and development of complex systems. One of the major benefits of SDL is the possibility to graphically describe a complex system, as well as the capability to analyze the system before implementation. This thesis evaluates SDL as a formal description language for use in an embedded platform. To be able to map the properties and behaviour of an SDL system into a programming language, a Real Time Operating System (RTOS) must be used. We will evaluate all properties of SDL to get a overview of which properties can be mappe…
Ontological representation of texts, and its applicationsin text analysis
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad For the management of a company, the need to know what people think of their products or services is becoming increasingly important in an increasingly competitive market. As the Internet can nearly be described as a digital mirror of events in the ”real“ world, being able to make sense of the semi structured nature of natural language texts published in this ubiquitous medium has received growing interest. The approach proposed in the thesis combines natural language processing and ontologies to represent elements in texts and relations between them. These relations are used to determine what terms …
From Live Sequence Charts to implementation : a study of the LSC specification, the execution of behavioral requirements and exploring the possibilit…
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad In the article ”From Play-In Scenarios to Code: An Achievable Dream” [8] D.Harel outlines an exiting new way of developing software with the aid of the new and expressively powerful language of live sequence charts (LSC) [1] for describing message sequencing. The language of LSC is a highly visual approach for modeling behavioral requirements and is based on message sequence charts [13]. LSC introduces the ability to specify mandatory behavior in charts through the notion of “liveness”, events that must happen. The development process described involves using a friendly capture method called “play-in…
Et studie i applikasjonsutvikling for ulike kommunikasjonsteknologier og UI på mobilterminaler
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad Den siste tiden er mobiltelefoners bruksområder blitt kraftig utvidet i form av støtte for tredjepartsprogramvare. SEA (Smart Energy Applications AS) har utviklet et trådløst styringssystem for smarthus basert på Bluetooth. I denne sammenhengen ønsker SEA å undersøke mulighetene for å benytte mobilterminaler til styring av Bluetooth nettverket. I denne oppgaven evalueres applikasjonsplattformer og kommunikasjonsteknologier, spesielt J2ME (Java 2 Micro Edition), Bluetooth og GPRS, med fokus på brukergrensesnitt. Videre diskuteres løsninger for trådløs styring av SEAs Bluetooth nettverk, for å avgjøre …
MDA and integration of legacy systems
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad OMG’s Model Driven ArchitectureTM, MDATM, is the new paradigm of software development and a new way of writing specifications and developing applications, based on a platform-independent model (PIM). MDA divorces implementation details from business functions. Thus, it is not necessary to repeat the process of modeling of applications or system’s functionality and behavior each time a new technology comes along. With the MDA, it is easier to integrate the new applications with the old application that is already installed. In the real time distributed telecommunication system, MDA addresses the chall…
