Single-photon emission computed tomography (SPECT) is important for imaging radioactivity distributions in vivo. Quantitative SPECT is limited due to attenuation and scatter contribution. Approximations such as constant attenuation and mono-exponential scatter functions will not be valid for non-homogeneous regions. A correction method is described where non-uniform density-maps are used in the at

The lottery question asks whether you would stop working, continue working in the same job or continue working in a different job if you won a sum of money large enough to allow you to live on it comfortably for the rest of your life without working. This literature review reports the results of 22 surveys carried out between 1955 and 2005 where this issue was raised in connection with basic incom

Cellobiose dehydrogenase (CDH) is a versatile bioelectrocatalyst lately at focus due to its sugar oxidising properties in combination with its inherent ability for direct electron transfer communication with electrodes making it possible to be used in bioanodes in the enzymatic fuel cells (EFCs), self-powered biosensors, and biosupercapacitors. During the last 20 years, many new nanomaterials and

This presentation will give an overview of a peer learning model called Supplemental Instruction - Peer Assisted Study Scheme (SI-PASS). SI-PASS was invented at the University of Missouri in Kansas City, USA in the early1970s and was then directed to Universities and for the university students. In this presentation, the focus and discussion will be on how SI-PASS can be implemented in secondary s

The complexity of human tibiofemoral joint motion is now better understood with the advancement of new methodologies to measure tibiofemoral kinematics in vivo. Marker clusters anchored to stainless steel bone pins inserted directly into the femur and tibia provide the most sensitive and accurate means for directly measuring skeletal tibiofemoral joint motion. Despite its invasiveness, this techni

Introduction: Elevated pulmonary vascular resistance (PVR) is observed in both physiological and pathological states. Pulmonary hypertension (PH) is a condition associated with significant morbidity and mortality in neonates and children and curative pharmacotherapy is lacking in most cases. In utero, a high PVR allows for blood to bypass the lungs through the open ductus arteriosus (DA). Vascular

Popular Abstract in Swedish Dagligen produceras hos en vuxen människa det helt otroliga antalet av 300 miljarder (300.000.000.000) blodkroppar. De flesta är röda blodkroppar som ansvarar för att transportera syre från lungorna till alla celler i kroppen samt koldioxid i andra riktningen. Vidare finns olika sorters vita blodkroppar som skyddar oss från infektioner samt blodplättar (eller trombocyteHematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. In acute myeloid le

This thesis focuses on how district heating utilities may work with fault handling in customer installations as a tool to reduce their return temperature levels. Reduced return temperatures would make it possible to improve the efficiency of the district heating systems and decrease their environmental impact. Faults in the customer installations cause high return temperatures that increase the re

Background: Herbivores modify the structure and function of tundra ecosystems. Understanding their impacts is necessary to assess the responses of these ecosystems to ongoing environmental changes. However, the effects of herbivores on plants and ecosystem structure and function vary across the Arctic. Strong spatial variation in herbivore effects implies that the results of individual studies on

Most companies and organizations are primarily interested in universities' educational activities and to a lesser extent in universities' research activities. Against this background, it is strange that the research on collaboration between universities and the surrounding society is primarily directed towards research collaboration between universities and companies/organizations and to a lesser

Popular Abstract in Swedish Systemisk skleros (SSc) är en relativt ovanlig reumatologisk sjukdom som kan engagera många av kroppens organ. Sjukdomen kallas ibland också för sklerodermi. Typiskt för sjukdomen är att huden omvandlas till fibros och blir hård och stram över olika delar av kroppen. Typiskt för sjukdomen är också att drabbade patienter har försämrad funktion i sina blodkärl, framförallSystemic sclerosis (SSc) is a systemic rheumatic disease with significant mortality and morbidity. Different estimations of disease prevalence and incidence have been presented from various parts of the world. While lung involvement is a common cause of SSc-related death, a majority of SSc patients suffer from symptoms originating in the gastrointestinal (GI) tract. By combining data from a popu
