Glucosides attached to proteins and lipids have been shown to modulate the activity of signal transduction pathways regulating growth and patterning processes during animal development. In particular, O-linked glycans such as glycosaminoglycans (GAGs) have been implicated in modulation of growth factor signaling pathways. GAGs are unbranched polysaccharide chains composed of repeating disaccharide

We study the stability of systems of three giant planets orbiting 3-8 M☉ stars at orbital distances of >10 au as the host star ages through the main sequence (MS) and well into the white dwarf (WD) stage. Systems are stable on the MS if the planets are separated by more than ~9 Hill radii. Most systems surviving the MS will remain stable until the WD phase, although planets scattered on to small p

Future wireless networks, the systems beyond 3G, will be a combination of different wireless systems. With only one terminal a user should be able to connect to different type of operators, technologies and systems. The issue is also to make the terminal staying online connected, when these changes are made. Both intrasystem handovers and intersystem handovers should be supported by such terminals

Popular Abstract in Swedish Denna avhandling syftar till att belysa vilket professionskunnande som blivande lärare ges möjlighet att utveckla under sin högskoleförlagda utbildning och hur detta professionskunnande kan karaktäriseras. Detta belyses genom ett antal forskningsfrågor: Vilka olika undervisningspraktiker konstituerar den högskoleförlagda lärarutbildningen? På vilket sätt upprättas dessaThe starting point for this dissertation was the reform of the school system in Sweden with consequences for teachers´ work and new demands on their professional knowledge. This thesis aims to illuminate the issue of what professional knowledge student teachers are offered during their time in the university, and how this professional knowledge can be characterised. This is carried out with respec

Within a UN Joint Programme titled “Enhancing the Capacity of Turkey to Adapt to Climate Change” a systems approach workshop was carried out in Adana, Turkey with broad stakeholder participation. The participants applied systems thinking approach, causal loop diagramming methodology and systems analysis to examine the potential impacts of projected climatic changes on natural ecosystems and socio-

Robotic force control refers to the control and programmable specification of the interaction forces between a robot end effector and the work object, where either the end effector or the work object is attached to the robot manipulator. A rudimentary approach is to consider the joint torques and controlled variables, and then to compute those torques such that a presumably rigid manipulator effec

Popular Abstract in Swedish Markören LE i kinesiska är speciell av flera olika skäl. Bland annat kan den uppträda på två ställen i en sats, dels direkt efter ett verb och dels i slutet av en mening. Beroende på var den uppträder kan den ofta - men inte alltid - påverka meningen på olika sätt. Det är en av anledningarna till att språkvetare ofta har valt att se LE som två olika markörer med olika fThe grammatical marker LE in Mandarin Chinese can occur in two syntactic positions, either immediately following the verb or at the end of a sentence. Traditionally, it has been described as two homophonous but syntactically distinct morphemes, verbal LE and sentence-final LE. This view seems to be based on assumptions about (1) the historical origin of LE, (2) the relation between LE and its coun

Kapitlet undersöker hur nya andliga och vetenskapslika diskurser inom de nya verksamheterna introduceras och tillämpas i det svenska samhället i sökandet efter identitet, mening och hälsa. I fokus står nya entreprenörer som under senare år har etablerat sig som terapeuter eller coacher och som erbjuder personlig utveckling, har skapat egna utbildningssystem med egencertifiering och som även etable

Vad är vetenskapsteori? Vad är skillnaden mellan bra och dålig forskning? Hur skeptisk bör man förhålla sig till vetenskapen? Behövs kunskapsutbyte över disciplingränserna? Det är en del av de frågor som tas upp i denna bok. I boken redovisas även de skilda angreppssätt som vanligen används i samband med klinisk forskning, epidemiologi och fallstudier. Den etiska prövningen av projekt presenteras
