The diagnosis of acute, non-traumatic diseases of the lower respiratory tract requires exact knowledge of the specific anatomy, physiology and pathology of the pediatric chest. The absolutely and relatively smaller airways, as compared with those of adults, and the undeveloped collateral ventilation result in radiological appearances that are unique in children. Viral pneumonia is predominant only
Rotational coherent anti-Stokes Raman spectroscopy (CARS) has over the years demonstrated its strong potential to measure temperature and relative concentrations of major species in combustion. A recent work is the development and experimental validation of a CO2 model for thermometry, in addition to our previous rotational CARS models for other molecules. In the,present work, additional calibrati
The SI-mediated carotenoid to BChl a energy-transfer pathway and carotenoid radical formation have been studied using femtosecond time-resolved transient absorption spectroscopy. A series of LH2 complexes (LH2 = light-harvesting complex 2) from Rhodobacter sphaeroides incorporating carotenoids neurosporene, spheroidene, and spheroidenone were used to explore the effect of conjugation length. The S
Objective: Oligoclonal bands (OBs) in electrophoresis of cerebrospinal fluid (CSF) are present in multiple sclerosis and here is investigated whether these also occur in experimental autoimmune encephalomyelitis (EAE). Material and methods: Experimental autoimmune encephalomyelitis was induced in 42 DA rats after immunization with rat spinal chord homogenate and the occurrence of OBs were detecte
Time-resolved absorption spectroscopy was used to study the femtosecond and picosecond time scale electron injection from the excited singlet and triplet states of Ru(dcbpY)(2)(NCS)(2) (RuN3) into titanium dioxide (TiO2) nanocrystalline particle film in acetonitrile. The fastest resolved time constant of similar to30 fs was shown to reflect a sum of two parallel ultrafast processes, nonergodic ele
Popular Abstract in Swedish Politiskt deltagande är ett komplext studieobjekt. I denna studie har det politiska deltagandet studerats utifrån att det i grunden handlar om aktiviteter som syftar till att påverka offentliga beslut. Följande frågeställningar ligger till grund för studien: (1) Hur förhåller sig olika former av politiskt deltagande till idén om politisk jämlikhet? (2) Hur kan vi teorePolitical participation is promoted as a central component in a democracy. But what specifically is it that makes participation valuable and how do different forms of participation differ in regard to outcomes? A central aim of this study is to understand why different forms of participation produce different kinds of effects. The argument developed is that participation can be understood as havin
Reactions of the triosmium cluster [HOs3(CO)(10)(eta(1):eta(1)-OC4H2CCH3)] with a series of aromatic aldehydes under mild conditions result in condensation of the ligand methyl group with the aldehyde C=O moiety to give typical aldol condensation products.
Ex vivo lung perfusion (EVLP) is a novel procedure designed to rapidly assess and recondition unusable donor lungs for transplantation (LTx). EVLP may reduce graft immunogenicity and allorecognition via removal of passenger leukocytes. We aimed to explore this hypothesis using human EVLP and in vitro analysis.
In the upper airway, the production of antimicrobial peptides (AMPs) protects against bacteria, viruses and fungi. Previous investigations have revealed downregulated expression of AMPs in different manifestations of allergic disease. In this study, we examined the expression of LL-37, RNase7 and LEAP-2 in tonsillar tissue and studied a possible relation to seasonal allergic rhinitis (SAR).
Rotational CARS N-2 thermometry has been developed for improved accuracy in spatial flame regions with high concentrations of either H-2 or CH4, which are typical conditions on the fuel side of diffusion flames. In initial validation experiments up to 700 K, rotational CARS measurements were performed in binary mixtures of H-2 and N-2. Subsequent spectral evaluation with commonly used N-2-N-2 Rama
This paper traces the intellectual effects of an encounter between Stig Kanger and Donald Davidson -two very different philosophers working in two seemingly unconnected areas. Their meeting in Oslo 1979 led the latter to improve his influential theory of radical interpretation and gave the former an inspiration for a rather striking paradox in preference logic. But, as we show, the paradox can be
Popular Abstract in Swedish Urinvägsinfektioner (UVI) är en av människans vanligaste bakteriella infektioner och drabbar både kvinnor och män. Kvinnor drabbas av UVI under hela sitt vuxna liv, medan UVI incidensen hos män ökar efter 40 – 50 års ålder pga. ökande problematik i urinvägarna med prostataförstoring, m.m. UVI orsakas av ett flertal olika bakteriearter, men tarmbakterien Escherichia coliUrinary tract infections (UTI) are among the most common human infections, and febrile UTI with bacteremia the most severe form. The relation between bacteria and host decides disease severity. The dominating uropathogen is Escherichia coli (E. coli). P fimbriae are the virulence factor of E. coli most clearly associated to severe disease. P fimbriated E. coli predominated in bacteremic febrile UT
In order to compare measurements in different laboratories and with different models and measuring principles a small Round Robin test was suggested. 12 test institutions were able to join the study (with foot model sizes from 254 mm to 275 mm and test boot sizes from 41 to 44). We got also a declaration of interest from 2 other institutes that were not able to carry out the tests now. A database
The author sets out to analyse a number of representations of the biblical Hagar figure in African American and white American culture. Spivak (1988) has problematized the marginalization concept with regard to the study of the third world subject, arguing that knowledge always expresses the interests of the knowledge producers, and that Western academic research is always colonial. The aim of the
Molecularly imprinted polymers (MIPs) are man-made polymeric materials with molecular recognition abilities. The polymers mimic the molecular recognition of natural molecular recognition elements, such as receptors and antibodies, by binding target molecules in a highly selective manner. The interactions between MIPs and their targets are of non-covalent or covalent nature, or a mixture thereof. F
