Sammanfattning : Turbulent mixing is present in many pulp and paper processes. It is a particularly important factor in the design and improvements of the paper machine headbox, influencing the final paper structure. LÄS MER
Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER
3. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies
Sammanfattning : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. LÄS MER
Sammanfattning : Trial and error and the use of highly time-consuming methods are often necessary for investigation and characterization of nonlinear systems. However, for the rather common case where a nonlinear system has linear relations between many of its degrees of freedom there are opportunities for more efficient approaches. LÄS MER
5. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods
Sammanfattning : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. LÄS MER
