Individual and trophic efficiencies of size-structured communities are derived from mechanistically based principles at the individual level. The derivations are relevant for communities with a size-based trophic structure, i.e. where trophic level is strongly correlated with individual size as in many aquatic systems. The derivations are used to link Lindeman's trophic theory and trophic theory b

Chromosome numbers are listed for 413 species of angiosperms from the Aegean Islands, based on collections and counts by Runemark and co-workers. Name, chromosome number and collection details (incl. geographical coordinates) are listed for each species. In almost all cases vouchers are at LD.

The effect of a new developed process for biogas boosting was studied at a municipal wastewater treatment plant in industrial scale over the period of three years. After pre-selection studies in the lab and short industrial setups, four hydrolytic enzymes and sodium citrate were combined and tested for a two-year period. The year 2007 was picked as reference year. In February 2008, the dosage was

BackgroundDuring bacterial infections of the airways, a Th1-profiled inflammation promotes the production of several host defense proteins and peptides with antibacterial activities including -defensins, ELR-negative CXC chemokines, and the cathelicidin LL-37. These are downregulated by Th2 cytokines of the allergic response. Instead, the eosinophil-recruiting chemokines eotaxin-1/CCL11, eotaxin-2

Coherence in optics and transport is investigated for quantum cascade lasers. While coherence provides oscillations in the gain recovery if the tunnel coupling surpasses the broadening, incoherent hopping transport can fail in the opposite case. (C) 2008 Optical Society of America

Protection of the environment in times of armed conflict has traditionally been viewed through the lens of the laws of armed conflict or international humanitarian law. However, protection of the environment in relation to armed conflict encompasses consideration of other areas of law. The articles in this special issue explore the gaps and possible solutions for addresing the deficiencies of the

The aim of this multicenter study was to investigate whether a computer-assisted diagnosis (CAD) system could improve performance and reduce interobserver variation in bone-scan interpretations of the presence or absence of bone metastases. Methods: The whole-body bone scans (anterior and posterior views) of 59 patients with breast or prostate cancer who had undergone scintigraphy for suspected bo

Hypoxic preconditioning is thought to rely on gene products regulated by hypoxia-inducible factor (HIF)-1. Here, we show that the HIF-1 target gene cyclin-dependent kinase inhibitor 1, p21(WAF1/CIP1), is essential for neuroprotection by hypoxic/aglycemic or erythropoietin preconditioning using wild-type and p21(WAF1/CIP1)-deficient neurons. Furthermore, overexpression of wild-type p21(WAF1/CIP1) o

Neutron-deficient nuclei with N = 126 have been populated following projectile fragmentation of a U-238 beam with energy 1 GeV/A. The decay of several previously reported isomers has been measured. This will allow us to calculate high-spin isomeric ratios and compare them with model calculations to allow a better understanding of the reaction mechanism.

The main function of erythropoietin (EPO) is in hematopoiesis where EPO stimulates increased proliferation, survival and differentiation of erythrocytic precursors in response to hypoxia. The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. Recombinant human EPO (rhEPO) is also used in treatment of cancer patient

A search for a Standard Model Higgs boson decaying via H -> ZZ -> l(+)l(-) nu(nu) over bar, where l represents electrons or muons, is presented. It is based on proton-proton collision data at root s = 7 TeV, collected by the ATLAS experiment at the LHC during 2011 and corresponding to an integrated luminosity of 4.7 fb(-1). The data agree with the expected Standard Model backgrounds. Upper limits

Nanowires were grown by means of a novel aerosol-based method called Aerotaxy. Here an aerosol of Au catalyst nanoparticles in N-2 is mixed with MOVPE precursors in a flow-through reactor at atmospheric pressure, whereby nanowires are produced continuously in high concentrations. We demonstrate the possibility of in situ doping of the NWs and the realization of well-controlled p-type GaAs nanowire

Generalized frequency division multiplexing (GFDM) is a new digital multicarrier concept. The GFDM modulation technique is extremely attractive for applications in a fragmented spectrum, as it provides the flexibility to choose a pulse shape and thus allows reduction of the out-of-band leakage of opportunistic cognitive radio signals into incumbent frequency space. However, this degree of freedom

Laminar burning velocities of syngas/air premixed flames, varying with H-2/CO ratio (from 5/95 to 75/25) and N-2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich.

Popular Abstract in Swedish Diabetes är en av de vanligaste folksjukdomarna och tusentals diagnostiseras med sjukdomen varje år. Det finns två typer av diabetes, typ 1 och typ 2. I typ 1 förstörs de insulin producerande β-cellerna som finns i de Langerhanska öarna av kroppens immunförsvar. β-cellerna har till uppgift att reglera blodsockernivåerna. Avsaknaden av egen insulinproduktion leder till dDiabetes affects enormous amounts of patients. In type 1 diabetes the insulin producing β cells in the islet of Langerhans are destroyed by the immune system. The β cells, which are located in the pancreas, regulate blood glucose levels. The lack of insulin production requires administration of insulin. This is accomplished by insulin injections. Even though the treatment methods have been improve

Terahertz spectroscopy is employed for the noncontact measurement of transversal mobility in InP nanowires, wherein photonic effects (waveguiding of excitation beam and propagation of terahertz beam in a complex gradient environment) were successfully deconvoluted. Monte Carlo calculations accounting for electron localization and heavy doping were used to determine electron momentum relaxation tim
