Aspects on the Regio and Stereo Selectivity in the Hydrolsilylation of 1,3-Dienes

Popular Abstract in Swedish Hydrosilyleringsreaktionen är formellt en addition av en hydrosilan till ett omättat system. Reaktionen är oftast katalyserad av en övergångsmetall, och i denna process är det möjligt att påverka på vilket sätt additionen sker. Denna avhandling är en sammanfattning av fyra artiklar som behandlar regio-, stereo- och kemoselektivitet vid addition av hydrosilaner till konjThis thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved. Optically active heterobidentate P,N ligands were synthesised f

The Effect of Visual Gender on Abuse in Conversation with ECAs

Previous studies have shown that female ECAs are more likely to be abused than male agents, which may cement gender stereotypes. In the study reported in this paper a visually androgynous ECA in the form of a teachable agent in an educational math game was compared with a female and male agent. The re-sults confirm that female agents are more prone to be verbally abused than male agents, but also

Acute improvement of contralateral hand function after deafferentation

To study cortical re-organisation after acute hand deafferentation, we investigated 10 experimental subjects and 10 controls for function in the left hand, before, during and after tourniquet induced anaesthesia of the right hand. fMRI was performed in three experimental subjects. Tourniquet-induced right hand anaesthesia resulted in rapid significant improvement in grip strength, tactile discrimi

Personal Value

Certain things, like justice, have impersonal value, other things, like your children, carry personal values: they have value for you. Besides whatever value, period, they have, they are valuable to you. The philosophical as well as non-philosophical literature is inundated with suggestions about the kinds of thing that are good-for us or, if it is a negative personal value, what is bad-for us. Fo

A 30 GHz 90-nm CMOS Passive Subharmonic Mixer with 15 GHz Differential LO

A new passive subharmonic mixer topology is presented and compared to a previously published passive topology. The comparison is conducted using simulations at 30 GHz with a 90-nm CMOS design kit. The advantage of the new passive subharmonic mixer is that it only requires a differential local oscillator (LO) signal, compared to the previously published mixer that requires a quadrature LO signal. T

Berättelser om det kränkta rummet : Processen i det terapeutiska rummet och betydelsen av bemötandeförloppet i återhämtningsprocessen vid allvarliga psykiska svårigheter

The present thesis involves a process evaluation of what occurred in the treat¬ment of seven young patients in institutional care diagnosed with schizophrenia: what happened in the encounters between staff and patients in a ward environ¬ment designed to provide constant care, and what facilitated or hindered rehabili¬tation efforts. The aim of the process presentation was to portray the treatment

Global effects of the Chicxulub impact on terrestrial vegetation - Review of the palynological record from New Zealand Cretaceous/Tertiary boundary

Analysis of pollen and spore assemblages from both terrestrial and near-shore marine sediments in New Zealand reveal an instant and dramatic mass-kill of the land plants in close association with the Cretaceous-Tertiary boundary (KTB) event. The turnover in the palynoflora is followed by a recovery succession, the most prominent feature of which is an interval dominated by fern spores (fern spike)

Increasing competitiveness through concurrent development of product and packaging

Extending the product development process to also include the concurrent design of product and packaging is expected to increase efficiency and effectiveness in the development process. Apart from the obvious advantage of reducing the lead times of the development project, improving environmental impact by reducing the consumption of raw material due to the possibility of facilitating a "tailor ma
