1(2)-Aryl-5-methylsulfonyltetrazoles react with ethylene glycol, di- and triethylene glycols, and tris(2-hydroxyethyl)amine in acetonitrile in the presence of sodium hydroxide to give tetrazole-containing ethers. The products can be used as polydentate ligands for biomimetic studies.
Large and small interstitial proteoglycans were purified from different bovine tissues, i.e. cartilage, sclera, tendon, aorta, cornea, and bone. The structure of the molecules was compared using the glycerol spraying/rotary shadowing technique for electron microscopy. Large proteoglycans from sclera and tendon have a core protein with a domain structure similar to that previously reported for cart
KIT is a tyrosine kinase receptor expressed by several tumours, which has for specific ligand the stem cell factor (SCF). KIT is the main oncogene in gastrointestinal stromal tumours (GISTs), and gain-of-function KIT mutations are present in 70% of these tumours. The aim of the study was to measure and investigate the mechanisms of KIT activation in 80 KIT-positive GIST patients. KIT activation wa
This essay is about Urak Lawoi, an indigenous people in Andaman Sea outside the West Coast of Thailand. The study shows what has happened to them when being deprived of their territory and forced to abandon their culture, lifestyle and traditional economic subsistence. Urak Lawoi have until recently maintained a culture, language and life style set apart from that of the rest of Thai society. Dur

The first results from the Stopped Beam RISING experimental campaign performed at the GSI laboratory in Darmstadt, Germany, are presented. RISING (Rare ISotope INvestigations at GSI) constitutes a major new experimental program in European nuclear structure physics research aimed at using relativistic‐energy, projectile‐fragmentation reactions to study nuclei with exotic proton‐to‐neutron ratios.
The use of a hybrid copper and fiber architecture is attractive in both fixed access and mobile backhauling scenarios. This trend led the industry and academia to start developing the fourth generation broadband system, which aims at achieving bitrates of 1 Gbps over short copper loops. In this context, accurate models of short twisted-pair cables operating at relatively high frequencies are key e
The need for keeping manufacturing and workplacesin Europe calls for new ideas and concepts for productiverobots with focus on their usefulness for Small andMedium sized Enterprises (SMEs). The activitiesfrom the Robotics Research at LTH, [3], [4], [2], andin particular those related to the SMErobot project[1] comprise efforts in this direction. The SMErobotproject is a recently started four-year-
Hybrid vehicles have attracted tremendous attention during the last years. Increasing environmental concern and a steady increase in fuel prices are key factors for the growing interest. Hybrid vehicles, which benefits from having at least two different energy converters and two different energy storage systems, have proven to have significant potential to improve fuel economy without reducing the
