Infrared light is the most common choice for illumination of the eye in current eye trackers, usually produced via IR light-emitting diodes (LEDs). This chapter provides an overview of the potential hazards of over-exposure to infrared light, the safety standards currently in place, configurations and lighting conditions employed by various eye tracking systems, the basics of measurement of IR lig

Debatten om brottsstatistik och vilka brott som ökar och inte är ofta infekterad. Diskussionen gagnas varken av under- eller överdrifter, utan borde hållas saklig. Sanningen är att ja, en del brott minskar och Sverige är internationellt sett mycket tryggt. Men det finns också mörka moln, exempelvis när det gäller skjutvapenrelaterat våld och explosionsvåld – områden där Sverige har mycket stora prThe debate on crime statistics and which crimes that are increasing and which that are decreasing, is often infected. The discussion is neither benefited from understatements nor exaggerations, but should be kept factual. The truth is that yes, some crimes are decreasing and Sweden is very safe internationally. But there are also dark clouds, such as firearm-related violence and explosive violence

Förmaksflimmer drabbar mer än 3 procent av Sveriges vuxna befolkning. Detta gör förmaksflimmer till ett vanligt tillstånd på akutmottagningen, dit patienterna kommer med olika symtom som andfåddhet, hjärtklappning, trötthet, bröstsmärta eller oroskänsla. Vid tromboembolisering till hjärnan kan patienten drabbas av stroke, synkope eller sänkt medvetandegrad. Det är därför viktigt att uppmärksamma oAtrial fibrillation (AF) is the most common tachyarrhythmia. When handling patients with AF at the emergency care department it is of utmost importance to take a structural approach, make the right diagnosis, take care of the risk and/or trigger factors, treat and make sure there is an adequate follow-up.

BACKGROUND:Although oxygen therapy has been used for over a century in the management of patients with suspected acute myocardial infarction (AMI), recent studies have raised concerns around the efficacy and safety of supplemental oxygen in normoxaemic patients.OBJECTIVE:To synthesise the evidence from randomised controlled trials (RCTs) that investigated the effects of supplemental oxygen therapy

Electrocardiographic Decision Support - Myocardial Ischaemia (EDS-MI) is a graphical decision support for detection and localization of acute transmural ischaemia. A recent study indicated that EDS-MI performs well for detection of acute transmural ischaemia. However, its performance has not been tested in patients with non-ischaemic ST-deviation. We aimed to optimize the diagnostic accuracy of ED

THERE ARE STILL MANY UNKNOWNS CONCERNING THE ROLE OF THE WEST, ESPECIALLY THE UNITED STATES, IN THE ISLAMIC REVOLUTION.

En grupp psykologer presenterar här ett förslag till lösning på bristen på psykiatrer i landet. Specialistkompetenta psykologer kan bli ett värdefullt tillskott och avlastning inom psykiatrin, skriver de.

The fundamentals of analyte extractable fraction, solubility, partitioning and mass transfer resistance in supercritical fluid extraction were studied using inverse modeling. These phenomena are essential for understanding, predicting and optimizing the supercritical fluid extraction process. Carotenoids, chlorophyll A, ergosterol and total lipids were extracted from the microalgae Chlorella sp. T

Mitigating degradation is essential for extending the lifetime of solid oxide electrochemical cells (SOCs). The conditions leading to degradation, e.g. overpotentials, gas partial pressures, thermal gradients are hard, if not impossible, to retrieve experimentally. Thus, to deconvolute the response from cell testing, modeling can be applied to understand the degradation phenomena in greater detail

Tuft cells are gastrointestinal (GI) sensory cells recognized by their characteristic shape and their microvilli “tuft”. Aims of the present study were to elucidate their regional distribution and spatial connections with satiety associated endocrine cells and nerve fibers throughout the intestinal tract. C57BL/6 J mice were used in the experiments. The small intestine was divided into five segmen
