2. 1. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

   Abstract : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.

4. 2. Bimanual movement control : insights from golf ball striking

   Author : Fredrik Tinmark; Toni Arndt; John Rasmussen; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

   Abstract : The aim of this thesis was to gain insight into the control of complex bimanual movements that are both fast and accurate. For this, skilled golf ball striking was used as a model in two experimental studies (I and III). READ MORE

5. 3. Permafrost Groundwater Dynamics : Modeling of vertical and lateral flows in the active layer across multiple scales

   Author : Alexandra Hamm; Andrew Frampton; Peter Kuhry; Jeffrey McKenzie; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; climate change; numerical modeling; hydrogeology; groundwater; naturgeografi; Physical Geography;

   Abstract : Hydrological processes in the Arctic are profoundly influenced by the presence of permanently frozen ground, known as permafrost. Conversely, permafrost is greatly affected by hydrological changes resulting from climate change. READ MORE

6. 4. Linking water and permafrost dynamics

   Author : Ylva Sjöberg; Steve Lyon; Andrew Frampton; Britta Sannel; Georgia Destouni; Michelle Walvoord; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; permafrost; hydrology; arctic; modeling; streamflow; geophysical measurements; ground thermal dynamics; groundwater; Physical Geography; naturgeografi;

   Abstract : The extent and dynamics of permafrost are tightly linked to the distribution and movement of water in arctic landscapes. As the Arctic warms more rapidly than the global average, profound changes are expected in both permafrost and hydrology; however, much is still not known about the interactions between these two systems.

7. 5. Burden Dynamics and Fragmentation

   Author : Nikolaos Petropoulos; Zongxian Zhang; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Drill and blast is a dominant technique in several surface and underground mines in the world. The purpose of this technique is to break rock mass into fragments, which can be handled by mining equipment. The identified major influencing factors in rock blasting are stress waves and gas pressurization. READ MORE
