The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues a
Laser-induced breakdown spectroscopy (LIBS) was used in this study to measure quantitatively the sodium (Na) and potassium (K) release from burning coal particles under oxy-fuel combustion environments. A specially designed laminar premixed burner was employed to provide a postflame environment with different O-2 and CO2 concentrations, in which the effects of O-2 and CO2 on the release of Na and
Popular Abstract in Swedish Cancer uppstår via genetiska förändringar som leder till ohämmad reglering av celltillväxt. Tumörer i mjukdelar utgör en grupp av solida tumörer, med över 100 histologiska typer. Mjukdelstumörer uppstår från mesenkymal vävnad, som inkluderar fett, bindväv, muskulatur, och det perifera nervsystemet. Mjukdelstumörer är en extremt heterogen grupp, både vad gäller morfologiThe focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas. The possible molecular targets for these aberrations were further studied t
We consider detection over intersymbol interference channels that are unknown at the receiver. For such a kind of systems, we consider an alternative approach to the design of a reduced-complexity receiver based on channel shortening without the explicit estimation of the channel impulse response. The proposed solution allows a simplification of the receiver architecture and a faster convergence f
Although advances in cardiopulmonary resuscitation have improved survival from cardiac arrest (CA), neurologic injury persists and impaired mitochondrial bioenergetics may be critical for targeted neuroresuscitation. The authors sought to determine if excellent cardiopulmonary resuscitation and postresuscitation care and good traditional survival rates result in persistently disordered cerebral mi
We present experimental measurements of the coherence of an undulator synchrotron radiation source near to the diffraction limit condition. These measurements have been done following two objectives. The first one is to verify a fundamental point of the theory of synchrotron radiation. To our knowledge, since it has been re-written by Geloni et al. [1], no experimental verification to validate the
Background: This study aimed to compare open appendectomy (OA) and laparoscopic appendectomy (LA) in children by analyzing the differences in outcomes between the two techniques. Materials and Methods: This was a single-institution retrospective study. Data were collected from the medical records of all children <15 years of age who underwent an appendectomy from 2006 through 2014. Preoperative pa
We have calculated the frequency-dependent exact-exchange (EXX) kernel of time-dependent (TD) density-functional theory employing our recently proposed computational method based on cubic splines. With this kernel we have calculated the linear density response function and obtained static polarizabilites, van der Waals coefficients, and correlation energies for all spherical spin-compensated atoms
Using the metric of channel capacity, three dual-antenna multiple-input multiple-output (MIMO) terminals with adaptive impedance matching were evaluated at LTE Band 13 in four different user scenarios using simulation. Each of the three terminals is equipped with a slot-monopole antenna and a planar inverted-F antenna (PIFA). The slot monopole is fixed at one edge of the chassis, whereas the locat
Hollow nanocapsules made of polyelectrolytes, extensively useful for biomedical and biotechnological applications, are produced with a simple Layer-by-Layer approach using liposomes as template. The biocompatible polymers, alginate and chitosan, are alternatively adsorbed onto liposomes allowing the achievement of small size hollow nanocapsules with an average diameter of similar to 280 nm. Hollow
The effect of modulating the structure of thin pentacene (C22H14) films by a nanopatterned inert substrate, known as hexagonal boron nitride nanomesh, is reported. Films of different thickness are grown and characterized by x-ray absorption, core-level photoemission, low-energy electron microscopy, microbeam low-energy electron diffraction, and scanning tunneling microscopy. Initially the pentacen
Researchers often statistically control for means when examining individual or age-associated differences in variances, assuming that the relation between the 2 is linear and invariant within and across individuals and age groups. We tested this assumption in the domain of working memory by applying variance-heterogeneity multilevel models to reaction times in the n-back task. Data are from the CO
"Arca lui Noe" ("Noah’s Ark", 1944) is based on a folk tale influenced by Bogomilism. Brother and Unbrother stand for the antinomic duality of the absolute principle. Fellow and Unfellow are indestructibly united. Unbrother cannot be mastered and Brother would be an ontic sterility if his fellow absent. However the Bogomilic vision becomes complicated in Blaga's meaning. The greybeard Brother, the
Background: Negative pressure wound therapy (NPWT) has remarkable effects on the healing of poststernotomy mediastinitis. Foam is presently the material of choice for NPWT in this indication. There is now increasing interest in using gauze, as this has proven successful in the treatment of peripheral wounds. It is important to determine the effects of NPWT using gauze on heart pumping function bef
