2. 1. On spinal mechanisms for reflex control in man : modulation of Ia-afferent excitation with changes in muscle length, activation level and fatigue

   Author : Maria M. Nordlund; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle; Medicin Teknik; Medicine Technology; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle;

   Abstract : To control muscle force, neural activation has to take alterations in muscle mechanics into account. This thesis assesses modulations in excitatory efficacy of Ia-afferents during muscle length changes at different levels of voluntary activation and during fatigue. READ MORE

4. 2. Comparison of dating methods for paleoglacial reconstruction in Central Asia

   Author : Natacha Gribenski; Krister N. Jansson; Arjen P. Stroeven; Frank Preusser; Jonathan M. Harbor; Marc Bateman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciation; Optically stimulated luminescence dating; Cosmogenic nuclide exposure dating; EMCCD camera; Physical Geography; naturgeografi;

   Abstract : Reconstruction of former Central Asian glaciers extents can provide valuable information about past atmospheric circulation variations. These extents, often marked by terminal moraines, need to be chronologically constrained. Cosmogenic nuclide exposure (CNE) dating is widely used to directly date moraines. READ MORE

5. 3. Response of Bolivian Altiplano Lakes to Seasonal and Annual Climate Variations

   Author : Ramiro Pillco; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENSO; terminal lake; bathymetry; lake level; water balance; lake routing; paleolakes; climate change; precipitation pattern; intermittent rivers.; Desaguadero River; Lake Titicaca; Lake Poopó;

   Abstract : The Bolivian Altiplano is situated between two mountain ranges, the western and eastern central Andes in South America. It has two major lakes, Lake Titicaca to the north, and Lake Poopó to the south, which both are important for the nature as well as for the living conditions on the Altiplano. The two lakes are the remnants of large paleolakes. READ MORE

6. 4. The roads in-between : causeways and polyagentive networks at Ichmul and Yo'okop, Cochuah Region, Mexico

   Author : Johan Normark; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; agency; architecture; becoming; Bergson; causeway; Cochuah; culture critique; Deleuze; difference; duration; event horizon; evolution; humanocentrism; Ichmul; ideology; in-between; index; materialtiy; Maya; Mexico; multiplicity; neo-materialism; network; polyagency; polyagent; posthumanism; practice; rhizome; road; sakbe; settlement archaeology; technoscience; temporality; Terminal Classic; virutality; Yo okop;

   Abstract : This dissertation has two aims: (1) To characterize and abandon the humanocentric archaeology that relies upon quasi-objects and to develop the polyagentive archaeology that relies upon actualizations of the virtual. (2) To exemplify the latter approach by studying how causeways (sakbeob) in the Maya area relate to temporality and materialtiy at, and around, the two neighbouring sites of Ichmul and Yo'okop in the Cochuah region of southeast Yucatan and west-central Quintana Roo in Mexico.

7. 5. VanT, a central regulator of quorum sensing signalling in Vibrio anguillarum

   Author : Antony Croxatto; Debra Milton; Edward G Ruby; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vibriosis; Vibrio anguillarum; quorum sensing; two-component phosphorelay systems; Molecular biology; Molekylärbiologi;

   Abstract : Many bacteria produce signal molecules that serve in a cell-to-cell communication system termed quorum sensing. This signalling system allows a bacterial population to co-ordinately regulate functions according to their cell number in a defined environment. READ MORE
