Thought-Images: The Quest for Visualisation of the Mental around 1900

This article examines the ever-actual desire to visualise and materialise thought-images in a historical perspective. The interest for research into thought imagery,and of visual proof production of thoughts, coincided with the invention of the camera and culminated somewhere around 1900. Together with other scientific circumstances that appeared up to 1900, such as the experimental psychology mod

Reaching beyond HIV/HCV: nelfinavir as a potential starting point for broad-spectrum protease inhibitors against dengue and chikungunya virus

Drug repurposing or re-profiling has become an effective strategy to identify novel indications for already-approved drugs. In this study, peptidomimetic FDA-approved HIV/HCV inhibitors were explored for their potential to be repurposed for the inhibition of the replication of dengue (DENV) and chikungunya virus (CHIKV) by targeting the NS2B-NS3 and NSP2 protease, respectively. MM/GBSA-based bindi

Costs and outcome for serious hand and arm injuries during the first year after trauma - a prospective study

Background: To study costs and outcome for serious hand and arm injuries during the first year after the trauma. Methods: In patients with a Hand Injury Severity Score (HISS) > 50, DASH and EQ-5D scores as well as factors related to costs within the health care sector, costs due to lost production and total costs were evaluated. Coxregression analysis stratifying for mechanism of injury was used t

Development of methods for the determination of vitamins A, E and beta-carotene in processed foods based on supercritical fluid extraction: a collaborative study.

New methodologies based on supercritical fluid extraction (SFE) have been developed for the determination of fat-soluble vitamins in processed foods. The results obtained so far indicate that SFE is well suited to extraction of fat-soluble vitamins from food products, although validation work is required to establish accuracy and precision. The vitamins investigated were A, E and beta-carotene, an

High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

Popular Abstract in Swedish Under de senaste årtiondena har både kraftsensorer och digitala kameror kommit att bli vanliga som sensorer i olika robotiktillämpningar. Denna avhandling behandlar olika problem inom visuell rörelseskattning och återkoppling, samt integrationen av dessa tekniker med reglering av kontaktkrafter för en industrirobot. Olika ämnen tas upp, från grundläggande teori till praOver the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. Different topics ranging from basic theory to system implementation and applications are treated. A new interface develo

The effects of physical activity and estrogen treatment on rat fast and slow skeletal muscles following ovariectomy

Decreased estrogen production is associated with changes in the skeletal, cardiovascular and muscular systems. At the level of skeletal muscles, it has been shown that a reduction in force production occurs at menopause but the underlying mechanisms are still unknown. The aim of the study was to investigate the effects of ovariectomy on myosin heavy chain (MyHC) composition. Additionally, we studi

Center-vortex solutions of the Yang-Mills effective action in three and four dimensions

We calculate the one-loop effective action of the SU(2) Yang-Mills theory for center-vortex configurations, both in 3D and 4D. We find that in both cases there are minima of the effective action, corresponding to vortices of the transverse size approximately 4/g(3)(2) and 1.7/Lambda((MS) over bar), respectively. The values of the effective actions at the minima are negative, suggesting that the Eu

Potential benefits of muscarinic M-3 receptor selectivity

Detrusor smooth muscle contains muscarinic receptors of the M-2 (approximate to2/3) and M-3 (approximate to1/3) subtypes. M-3 receptors are mainly responsible for normal micturition contraction, whereas, the role Of M-2 receptors has not yet been clarified. In certain disease states, M-2 receptors may also contribute to bladder contraction. Different muscarinic receptor subtypes can contribute to

Microarthropods mediate sperm transfer in mosses

Among flowering plants, animals commonly act as pollinators. We showed that fertile moss shoots attract springtails and mites, which in turn carry moss sperm, thereby enhancing the fertilization process. Previously, fertilization of mosses was thought to depend on the capacity of individual sperm to swim through a continuous water layer. The role of microarthropods in moss fertilization resembles
