Biomolecular motor systems are attractive for future nanotechnological devices because they can replace nanofluidics by directed transport. However, the lack of methods to externally control motor-driven transport along complex paths limits their range of applications. Based on a thermo-responsive polymer, we developed a novel technique to guide microtubules propelled by kinesin-1 motors on a plan

To better utilize existing wireless systems, they can be combined together to interact and thereby provide better balanced capacity. They can further profit from this by getting their ongoing connection moved from the current system to another. The main issues are to make this move without losing the ongoing connection and to make it seamless, i.e., without the user noticing it. This action of mov

Efficient pretreatment is necessary to make the wood-to-ethanol process more feasible. In this study, chips of different sizes were impregnated with SO(2) and steam-pretreated. Dilute-acid pretreatment together with subsequent enzymatic hydrolysis resulted in solubilization of between 69% and 73% of the fermentable sugars (glucose and mannose) in the raw material for the combinations of impregnati

This article explores and evaluates three common identifications of the woman in Revelation 12: Mary, mother of Jesus, Israel and the church. This is accomplished through the study of allusions, particularly to the Septuagint, that are embedded in the Greek text. Each verse describing the woman in Revelation 12 has connecting points with one or several texts in the Septuagint and seems to allude t

Background: The teenage years are the years when adolescents seek their identity, and part of this involves experimenting with tobacco. The use of tobacco as such, and norms among their friends, is more important to the adolescents than the norms of parents when it comes to using tobacco or not. The aim was to explore the significance of using snus for adolescents, and attitudes to snus, as well a

The deswelling behavior of cross-linked DNA gels reports on DNA-cosolute interactions and gives a basis for the development of responsive DNA formulations. An investigation of the deswelling kinetics shows that an increase in the surfactant tail length gives a pronouncedly slower deswelling kinetics. In the same conditions, single stranded gels exhibited faster deswelling kinetics when compared wi

This paper analyses a specific stage in the development of alignment system in Indo-European languages. It is argued that one of the most crucial stages is the appearance of binary features, which allows the language to develop into a form ready for dealing with complex functional demands.

Raoul Wallenberg har varit omdiskuterad såväl i Sverige som i utlandet efter hans försvinnande 1947. Uppmärksamheten för honom har gått i vågor. Ett särskilt fokus i artikeln är hur han framställs och brukas 2012, då hundraårsminnet av hans födelse uppmärksammas.

BACKGROUND: Isokinetic dynamometry is a useful tool to objectively assess muscle strength of children and adults in athletic and rehabilitative settings. This study examined test-retest reliability of isokinetic knee strength measurements in children aged 8 to 10 years and defined limits for the minimum difference (MD) in strength that indicates a clinically important change. HYPOTHESIS: Isokine

Data from measurements on the body burden Of (CS)-C-134, Cs-137 and K-40 in various Swedish populations between 1959 and 2001 has been compiled into a national database. The compilation is a co-operation between the Departments of Radiation Physics in Malmo and Goteborg, the National Radiation Protection Authority (SSI) and the Swedish Defense Research Agency (FOI). In a previous study the effecti

With the success of cisplatin (cis-diamminedichloroplatinum(II)), strong interest has developed in the application of inorganic metal complexes to the treatment of cancer. Research has focused on platinum( II) complexes with a variety of spectator ligands that provide novel physicochemical properties. In this paper we report a kinetic study of 1', 1'-bis(diphenylphosphino) ferrocenedichloroplatinu

The in vitro digestion of a self nano-emulsifying drug delivery system (SNEDDS) was visualized by cryogenic transmission electron microscopy (Cryo-TEM). The dynamic lipolysis model, simulating the environment of the gastrointestinal tract in fasted conditions, was used for this purpose. The results revealed that micelles are present during the entire lipolysis process. Oil droplets from the self n

We developed nine polymorphic microsatellite loci for the field vole, Microtus agrestis. The number of alleles ranged from five to 15 and observed heterozygosities ranged from 0.40 to 1.00. We also tested the microsatellite loci for amplification and polymorphism in the congeneric species Microtus arvalis. Five of the nine loci were successfully analysed in this species. The microsatellite markers

Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. The criticism concerns issues as for instance short slab spans (limited flexibility for future refurbishment), long production times,

Sarcomas are relatively rare malignancies and include a large number of histological subgroups. Based on morphology alone, the differential diagnoses of sarcoma subtypes can be challenging, but the identification of specific fusion genes aids correct diagnostication. The presence of individual fusion products are routinely investigated in Pathology labs. However, the methods used are time-consumin
