Due to the very limited availability of He-3, new kinds of neutron detectors, not based on 3He, are urgently needed. Here, we present a method to produce thin films of (B4C)-B-10, with maximized detection efficiency, intended to be part of a new generation of large area neutron detectors. B4C thin Films have been deposited onto Al-blade and Si wafer substrates by dc magnetron sputtering from (B4C)
A high interest in enterprise resource planning (ERPs) systems exists among small and medium sized enterprises (SMEs). This interest has created new ways of development of ERPs, such as open source ERP development. However, it is unclear what impact this has on diffusion of ERPs. To explore if open source ERP development impact diffusion of ERPs among SMEs a comparative investigation on proprietar
The MHC (Major Histocompatibility Complex) plays an important role in the immune system of vertebrates. MHC genes are extremely polymorphic and this variation is considered to be maintained by selection from pathogens. We investigate whether MHC diversity (number of different alleles per individual) affects the survival and recruitment of nestling house sparrows. We hypothesize that individuals wi
The myogenic response is the intrinsic ability of small arteries to constrict in response to increased intraluminal pressure. Although microRNAs have been shown to play a role in vascular smooth muscle function, their importance in the regulation of the myogenic response is not known. In this study, we investigate the role of microRNAs in the regulation of myogenic tone by using smooth muscle-spec
The ETV6/RUNX1 fusion gene, present in 25% of B-lineage childhood acute lymphoblastic leukemia (ALL), is thought to represent an initiating event, which requires additional genetic changes for leukemia development. To identify additional genetic alterations, 24 ETV6/RUNX1-positive ALLs were analyzed using 500K single nucleotide polymorphism arrays. The results were combined with previously publish
pH is a highly variable environmental factor for the root, and plant cells can modify apoplastic pH for nutrient acquisition and in response to extracellular signals. Nevertheless, surprisingly few effects of external pH on plant gene expression have been reported. We have used microarrays to investigate whether external pH affects global gene expression. In Arabidopsis thaliana roots, 881 genes d
Cytology is central in the diagnosis of malignancy in effusions. Ancillary techniques, mainly immunocytochemistry, have considerably improved the sensitivity but some 10% of all cases remain equivocal and require the addition of new diagnostic modalities. We have previously shown that strong nuclear telomerase activity determined with Telomere Repeat Amplification Protocol (TRAP) in situ is specif
Simvastatin is widely used to lower cholesterol levels in patients with cardiovascular diseases, although accumulating evidence suggests that statins, such as simvastatin, also exert numerous anti-tumoral effects.
The pathogenesis of diabetic retinopathy (DR) remains unclear but hyperglycemia is an established risk factor. Endothelial dysfunction and changes in Ca(2+) signaling have been shown to precede the onset of DR. We recently demonstrated that high extracellular glucose activates the Ca(2+)/calcineurin-dependent transcription factor NFAT in cerebral arteries and aorta, promoting the expression of inf
Galectins are defined by a conserved beta-galactoside binding site, which has been linked to many of their important functions in e.g. cell adhesion, signaling and intracellular trafficking. Weak adjacent sites may enhance or decrease affinity for natural beta-galactoside containing glycoconjugates, but little is known about the biological role of this modulation of affinity (fine specificity). We
Photoinduced interaction of thioglycolic acid (TGA) capped CdTe quantum dots (QDs) with certain antioxidants such as estrogens and flavonoids has been investigated by using steady state and time resolved fluorescence spectroscopy. Reduction of electron-hole recombination has been observed (i.e., fluorescence quenching) while adding antioxidants to CdTe QDs. The Stern-Volmer constant (K-SV), quench
Niganda phichai Pellinen, sp. n., is described from northern Thailand. The new species is diagnosed and illustrated, including details of the genitalia and DNA sequencing. Variability in the male genitalia of Niganda radialis Gaede is reviewed, and notes are presented on the facies of female N. radialis
A comparative study of the central and southern parts of the Palaeoproterozoic Svecofennian orogen in the Baltic/Fennoscandian Shield and the platform area to the east and south of the Baltic Sea indicates that at least these parts of the orogen are built up of several NW-SE trending, 100-300 km wide tectonic megadomains separated from each other and complicated by major zones of mostly dextral sh
Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquen has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic areas of the region, the neighboring Huantraico and La Matancilla plateaus, including new Ar-40/Ar-39 age results of major and trace elements as well as Nd, Sr and Pb isotopic
This manuscript presents the digital hardware realization of a wavelet based event detector for cardiac pacemaker applications. The architecture of the detector is partially folded to minimize hardware cost. An energy model is applied to evaluate the energy efficiency the sub-threshold (sub-VT ) domain. The design is synthesized in 65nm low leakage-high threshold CMOS technology, and it is shown t
The M-shell x-ray emission of highly charged tungsten ions has been investigated at the Livermore electron beam ion trap facility. Using the SuperEBIT electron beam ion trap and a NASA x-ray calorimeter array, transitions connecting to levels of the ground configurations in the 1500–3600 eV spectral range of zinc-like W44+ through cobalt-like W47+ have been measured. The measured spectra are compa
Abstract in UndeterminedUsing a sample of 7,260 university employees, we investigate how legitimacy, social and human capital influence the employees’ start-up propensity. We find that scientific legitimacy, as measured by the number of recently published peer reviewed scientific articles, and conference papers accepted had no significant effect. Scientific legitimacy measured as publications in n
