Gentrification is a current and often debated concept that concerns social changes in our cities. The concept relates to a development whereby areas earlier inhabited by less wealthy social groups are taken over by middle and upper middle-class residents. In the discussions of these changes, two perspectives have dominated. Representatives for the consumer perspective argue that gentrification occ
Background Acetabular cementation during total hip arthroplasty is considered difficult mainly due to the appearance and anatomy of the acetabulum. Improved cementation technique has been shown to improve the longevity of acetabular components. Method We designed a ceramic model to investigate the effect of varying the initial cement pressurization and cup introduction times on the depth of cemen
Recent immunohistochemical findings suggested that a constitutive nitric oxide synthase (cNOS) resides in endocrine pancreas. Here we provide direct biochemical evidence for the presence of cNOS activity in isolated islets. The regulating influence of this nitric oxide synthase (NOS) activity for islet hormone release was also investigated. We observed that cNOS activity could be quantitated in is
The development of the red colour in copper ruby alkali silicate glasses has been studied by means of ultraviolet/visible spectroscopy, TEM and EXAFS. The results show that in both red and slightly overstruck, brownish glasses the colour is due to clusters of metallic copper. Before striking non-coloured glasses contain mainly cuprous ions, Cu+. Tin acts as a reducing agent but also has an acceler
alpha-Trinositol (D-myo-inositol-1,2,6-trisphosphate), an isomer of the intracellular messenger IP3, has been studied for its anti-inflammatory and other effects in animal experiments and in human. The mechanisms of action remain unknown. Several human pathologies are associated with uncontrolled production of fibroblast growth factors (FGFs). FGF-2 induces vascular smooth muscle cell proliferatio
An all-solid-state fast-tuning lidar transmitter for range- and temporally resolved atmospheric gas concentration measurements has been developed and thoroughly tested. The instrument is based on a commercial optical parametric oscillator (OPO) laser system, which has been redesigned with piezoelectric transducers mounted on the wavelength-tuning mirror and on the crystal angle tuning element in t
We studied the foraging technique of Ospreys Pandion haliaetus during different wind speed conditions at Lake Hammarsjon, Sweden in autumn 2003. Different fishing techniques were used with a shift in relation to wind speed: (1) without hovering, (2) hovering with pure flapping flight, (3) hovering with flapping flight and gliding into the wind, and (4) hovering with pure gliding. The results suppo
Aim: To determine if children adopted to Swedish families from countries with a high carrier rate of methicillin-resistant Staphylococcus aureus (MRSA) are infected or colonized with MRSA. Methods: From January 2000 to May 2005, 23 adopted children from 6 countries were examined for MRSA at the University hospital in Lund after their arrival in Sweden. Results: Thirteen of the 23 children (57%) we
We give the emission function of the axially symmetric Buda-Lund hydro, model and present its simultaneous, high quality fits to identified particle spectra, two-particle Bose-Einstein or HBT correlations and charged particle pseudorapidity distributions as measured by BRAHMS and PHENIX in 0-30% central, roots(NN) = 200 GeV Au+Au collisions at RHIC. The best fit is achieved when the most central r
Two oligonucleotide primers were used for selective enzymatic amplification of a DNA segment encoding a major portion of the first constant region domain (CH1) of the human IgG1 heavy chain. The selective amplification was confirmed by use of subclass-specific oligonucleotide probes. Two 15-mer oligonucleotides, hybridizing with the alleles for the allotypes G1m(f) and (z), respectively, could the
While the use of radio technology for wireless data communications has increased rapidly, the wide variety of radio interfaces being used has made interference investigations hard to perform. With that in mind, we present a novel approach for analyzing packet radio communications, applicable to interfering heterogeneous networks, which leads to tractable analytical expressions. The core of the app
Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column. DOC is a heterogeneous mixture of molecules, some of which are imported from the watershed (allochthonous DOC) and others that are produced by autotrophs within the system (autochthonous DOC). We examined the importance of autochthonous versus allochthonous DOC in supporting the growth of p
