The formation of iron aluminide (FeAl) during the heating of Fe-40 at.% Al powder mixture has been studied using a differential scanning calorimeter. The effect of particle size of the reactants, compaction of the powder mixtures as well as the heating rate on combustion behavior has been investigated. On heating compacted discs containing relatively coarser iron powder, DSC data show two consecut
Objective: To determine the interobserver agreement (IOA) of neonatal seizure detection using the gold standard of conventional, multichannel EEG. Methods: A cohort of full-term neonates at risk of acute encephalopathy was included in this prospective study. The EEG recordings of these neonates were independently reviewed for seizures by three international experts. The IOA was estimated using sta
Popular Abstract in Swedish Varje dag produceras miljardtals nya blodceller, vilka exempelvis har som uppgift att transportera runt syre och försvara kroppen mot olika invaderande bakterier och virus. Dessa olika blodkomponenter har sitt ursprung i sällsynta blodbildande stamceller som återfinns i benmärgen. Dessa är så kallade vävnadsspecifika stamceller och har både förmågan att återbilda sig sjBlood cell formation, or hematopoiesis, is maintained by rare hematopoietic stem cells (HSCs) residing in the bone marrow (BM). HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in the production of mature effector blood cells. Aging is characterized
We extend the classical notion of an outer action alpha of a group G on a unital ring A to the case when alpha is a partial action on ideals, all of which have local units. We show that if alpha is an outer partial action of an abelian group G, then its associated partial skew group ring A(star alpha) G is simple if and only if A is G-simple. This result is applied to partial skew group rings asso
Kidney disease is a growing problem in the whole world. It is important to find these patients in an early state of the disease because then they can be treated and dialysis treatment can be avoided. To measure the glomerular filtration rate (GFR) an invasive technigue is used. In this thesis an equation to estimate GFR (eGFR) by drawing a blood sample and measure the concentration of cystatin C i
In application areas that process stream-like data such as multimedia, networking and DSP, the pipelined concurrent processing is frequently represented as a dataflow network of communicating computational kernels connected by FIFO queues. However, while dataflow is a natural medium for conceptualizing and modeling stream-processing systems, its adoption as a programming methodology has been hinde
Background: Systematic literature reviews and systematic mapping studies are becoming increasingly common in software engineering, and hence it becomes even more important to better understand the reliability of such studies. Objective: This paper presents a study of two systematic mapping studies to evaluate the reliability of mapping studies and point out some challenges related to this type of
High order splitting schemes with complex timesteps are applied to Kolmogorov backward equations stemming from stochastic differential equations in the Stratonovich form. in the setting of weighted spaces, the necessary analyticity of the split semigroups can easily be proved. A numerical example from interest rate theory, the CIR2 model, is considered. The numerical results are robust for drift-d
Objective: To investigate (i) the performance and agreement between various activity indices and response criteria in TNF-blockade of RA; (ii) the predictive ability of different response criteria and disease activity states regarding continuation of anti-TNF treatment of RA; (iii) Euro-QoL-5-dimensions utility development during TNF blockade of RA, PsA and SpA. Also, (iv) to develop a simple, uti
In this paper, we propose a novel interference cancellation method that exploits secondary data to estimate stationary interference components present in both the primary and the secondary data sets, thereby allowing for the removal of such interference from the data sets, even when these components share frequencies with the signal of interest. The algorithm estimates the present interference com
Objective and methods: Time-use methodologies have been proposed to be established research techniques when exploring aspects of daily occupations. In this study, two graphs illustrating the time arrangement of occupations as they appear in a continuous sequence were used in order to encourage individuals to reflect on their everyday life. The aim was to investigate the usefulness of a time-geogra
The long-range order in strongly coupled dipolar systems has been studied using large-scale simulations for systems containing up to 100 000 particles. It is found that the boundary conditions used strongly influence the result. It is found that a periodic system modeled with the minimum image approximation yields an artificial order, whereas the same system described using the Ewald summation tec
This review article focuses on advances and technical developments of the realm of membrane extraction techniques for the analytes that are (made) amenable to gas chromatographic analysis, and sheds light on the analytical applications to biological and environmental samples. In this review, the state of the art in this growing area of membrane extraction for gas chromatography is presented and se
There is a paucity of research literature concerning frailty in older persons from the health care professionals' perspective. Consequently, the purpose of this study was to elucidate health care professionals' view of frailty in older persons. An explorative, qualitative design was selected and four focus groups comprising 21 health care professionals were conducted, audiotaped, transcribed verba
An increase in large-scale agricultural investment in land has been going on since the global food crisis in 2008. Import-dependent countries have acquired large plots of land to secure food supplies. The investments had disastrous impacts on the local communities living on the land before the investment took place. Many have been expropriated and evicted from their lands, affecting their human ri
