Development of a Novel Promoter System for Thioglycoside Activation; and its application in the synthesis of a GD3 bis-lactam

Popular Abstract in Swedish En ny metod för att syntetisera avancerade kolhydrater har utvecklats. I en utvärdering har två kolhydratstrukturer, viktiga intermediat i ett nytt cancervaccin, syntetiserats.A novel promoter system IX/AgOTf (X=Cl or Br) for thioglycoside activation has been developed (paper I-II). The promoter system has been evaluated in the synthesis of two GD3 bis-lactam fragments (paper III).

Perception and judgement of life quality across projected societies

The focus of the presentation is on the individual’s comprehension of “citizenship”. Study and analysis of citizenship concerns a person’s co-operative interaction with various physical and social surroundings as well as the cognitive integration of these surroundings. A person can achieve this integration through development of his abilities of judgement. Thus the aim is to make apparent the kind

Internet Access and QoS in Ad Hoc Networks

It is likely that the increased popularity of wireless local area networks (WLANs) together with the continuous technological advances in wireless communication, also increase the interest for ad hoc networks. An ad hoc network is a wireless, autonomous, infrastructure-less network composed of stations that communicate with each other directly in a peer-to-peer fashion. When discussing mobile ad h

Acoustical detection of venous stenosis in Hemodialysis patients using principal component analysis

In this paper, a feature extraction method based on principal component analysis was developed for classification of the vascular access’s condition in hemodialysis patients. The assessment of the method was carried out by discriminating between before and after angioplasty sound recordings as well as before angioplasty and reference recordings. The results showed that when before and after angiop

The Interplay Between Selection And Constraints On Adaptive Divergence And Phenotypic Evolution

Under natural or sexual selection, individuals with advantageous traits or combinations of traits will be more successful than their peers at surviving and/or reproducing. Provided these traits are heritable, meaning that they have a genetic basis, the traits combinations which are selected for, will increase in frequency in the population. When selection is intense and persistent, adaptive traits

Speglingar av Småland

Varför är Småland ett landskap som fascinerar? Kanske för att det är så mångsidigt och omväxlande, likt en brokig mosaik. Dess historia är rik och man har aldrig kunnat tala om ett Småland eller en småländsk identitet. I denna antologi möts tio forskare kring frågan avd som egentligen är småländskt. Läsaren tas med till Astrid Lindgrens Värld och till det småländska Glasriket. De möte tyska och da

Quantum chemical characterization of oxide nanoparticles and interactions on their surfaces

Popular Abstract in English Nanotechnology is a quickly developing field, which applies objects of extremely small sizes to novel technological applications. These objects, so-called nanomaterials, have at least one dimension measured in nanometers, 10-9 meters. Nanoparticles are of interest to chemists due to their distinct properties, which differ significantly from the bulk material. This uniquTitanium dioxide and related oxide materials have been investigated using density functional theory calculations. Nanocrystalline particles were modelled by a finite cluster approach. The studies focus on the characterization of structural and electronic properties of TiO2 and related group-IV materials (SiO2, GeO2, SnO2), as well as, interactions on their surfaces. A set of bare cluster models o
