We present a new, to our knowledge, method for extracting optical properties from integrating sphere measurements on thin biological samples. The method is based on multivariate calibration techniques involving Monte Carlo simulations, multiple polynomial regression, and a Newton-Raphson algorithm for solving nonlinear equation systems. Prediction tests with simulated data showed that the mean rel
The central complement inhibitor factor I (FI) degrades activated complement factors C4b and C3b in the presence of cofactors such as C4b-binding protein, factor H, complement receptor 1 and membrane cofactor protein. FI is a serine protease composed of two chains; the light chain comprises the serine protease domain, while the heavy chain contains several domains: the FI and membrane attack compl
Using the metrics of channel capacity and multiplexing efficiency, the adaptive impedance matching (AIM) performances of two multiple-input multiple-output (MIMO) terminals with different antenna designs were evaluated and compared. The evaluation was performed in LTE Band 18 Downlink (860-875 MHz) under realistic usage conditions of two measured user handgrips and simulated propagation channels w
The single-aliquot regenerative-dose (SAR) protocols used in retrospective dosimetry for optically stimulated luminescence measurements have been mainly developed for archaeological and geological dating of quartz and feldspar. The aim in this study is to find a read-out protocol that can generate the most reproducible signal for household salt (NaCl) at absorbed doses below 100 mGy. The relation
This study describes and validates a new method for automatic segmentation of left ventricular mass (LVM) in myocardial perfusion SPECT (MPS) images. This is important for estimating the size of a perfusion defect as percentage of the left ventricle. METHODS: A total of 101 patients with known or suspected coronary artery disease underwent both rest and stress MPS and MRI. A new automated algorith
The natural radiative lifetime of the 3s 4p 1P1 level of neutral magnesium was measured by pulsed level-crossing spectroscopy at the short excitation wavelength of 202.6 nm. We obtained tau = 13.4(5) ns for this state, strongly deviating from a previous beam-foil result, but in good agreement with a multi-configuration Hartree-Fock calculation. A discussion of the applicability of the pulsed Hanle
Scand J Caring Sci; 2011 Online self-help tools for the relatives of persons with depression - a feasibility study Background: The Internet's potential as health care tool should be explored. Aim: One objective was to determine the feasibility of constructing a digitally based tool through an iterative design process in cooperation with potential users. The tool's purpose is to alleviate hardships
We present a portable system for non-invasive, simultaneous sensing of molecular oxygen (O-2) and water vapor (H2O) in the human paranasal cavities. The system is based on high-resolution tunable diode laser spectroscopy (TDLAS) and digital wavelength modulation spectroscopy (dWMS). Since optical interference and non-ideal tuning of the diode lasers render signal processing complex, we focus on Fo
In internal radionuclide therapy, a growing interest in voxel-level estimates of tissue-absorbed dose has been driven by the desire to report radiobiologic quantities that account for the biologic consequences of both spatial and temporal nonuniformities in these dose estimates. This report presents an overview of 3-dimensional SPECT methods and requirements for internal dosimetry at both regional
In dense passive radio frequency identification (RFID) systems, code division multiple access (CDMA) techniques can be used to alleviate severe collisions and thus enhance the system performance. However, conventional CDMA techniques are challenging to implement, especially for passive tags due to cost and power constraints. In this paper, we design a CDMA-based multi-reader passive ultra high fre
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
Stimulation of innovation is a hot topic around the world. The developed economies are nowadays significantly dependent on innovation for further growth. One central source of innovation is universities and their ability to turn new knowledge into value-adding innovations. One of these technology transfer measures is through the creation of university spinoffs (USOs). High-tech startups, however,
Sedan Sovjetunionens fall har Ryssland försökt att åter bli den stormakt de en gång var. Tidigt insåg den ryska staten att deras största tillgång var deras enorma energiresurser. Således fanns det starka initiativ till att bedriva en expansiv energipolitik men det som vid en första anblick anses vara ett ekonomiskt projekt kan ofta ha en dold agenda. I den här uppsatsen undersöks huruvida den rysk
Människohandeln är ett mångbottnat problem som får allt högre prioritet på den internationella agendan. Marknadsekonomiska principer om utbud och efterfrågan och social utsatthet som grund till offrens tillgänglighet och en ständigt växande globalisering ger upphov till nya vägar för brottslighetens expansion. Oavsett vilka orsakerna är, så är konsekvenserna förödande. Människors förmåga att utnytHuman trafficking is a multifaceted problem at the heart of the priorities of the international agenda. Principles of market economy with supply and demand and social vulnerability as a condition for the accessibility of victims, together with a constantly growing globalization contributes to this reprehensible phenomenon in today’s society. Regardless of which the reasons are, the consequences ar
Rekryteringen och användandet av barnsoldater regleras bland annat i TP I och II och i barnkonventionen med tillhörande fakultativa protokoll. Dessutom finns en mängd resolutioner från säkerhetsrådet på området. Tillsammans ger dessa instrument barn i väpnad konflikt ett visst skydd. Men fortfarande utnyttjas barn i stor utsträckning i konflikter, både av stater och av icke-statliga grupper. I uThe recruitment and use of child soldiers is regulated in, among other instruments, TP I and II and in the child convention and it’s optional protocols. There are also various resolutions from the security council on the topic. Together these instruments provide children in armed conflict with some protection. Unfortunately, despite the regulations in international law, children are used in confli
Trenden i samhällsbyggnadsbranschen visar på ett ökat intresse för innovation. Tidigare forskning har primärt fokuserats på produkt- och processutveckling, där forskningen kring tjänsteinnovation ännu inte fått genomslag. Konsultföretag beskrivs samtidigt som pådrivare av innovation. Detta har öppnat upp för vidare forskning kring hur konsultföretag, som erbjuder tjänster inom förändringsledning i
