Background Increased knee abduction during weight-bearing activities is suggested to be a contributing factor for the high knee injury risk reported in women. However, studies investigating gender difference in knee abduction are inconclusive. Objective To systematically review gender-differences in knee abduction during weight-bearing activities in individuals with or without knee injury. Methods

Value-based pricing is by many companies as well as in academia perceived as the preferred pricing model. The pricing literature includes a long-standing debate on pricing authority and centralized pricing authority can be associated with value-based pricing strategies. A critical success factor for value-based pricing is customer value assessment, and many companies have experienced challenges in

Beta-delayed proton emission from 20 Mg has been measured at ISOLDE, CERN, with the ISOLDE Decay Station (IDS) setup including both charged-particle and gamma-ray detection capabilities. A total of 27 delayed proton branches were measured including seven so far unobserved. An updated decay scheme, including three new resonances above the proton separation energy in 20 Na and more precise resonance

Using combined autoradiography and immunohistochemistry, we have compared (3H)-adenosine accumulation and GABA immunoreactivity in the chicken and rabbit retinas. Colocalization of the two markers was observed in a subset of amacrine cells and in certain cell bodies in the ganglion cell layer in both species and in a few horizontal cells in the chicken retina. Cells that contained only (3H)-adenos

Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas. Given their differing life histories, ecological theory would predict that the different groups of individuals should exhibit some level of niche segregation. This has rarely been investigated because of the difficulty in assigning migrating individuals

The concentrations of dioxins in fish oil and fish meal were determined with accelerated solvent extraction, using a novel integrated carbon fractionation extraction cell followed by a miniturized multilayer silica column and bioanalysis on a recently-developed chemically-activated fluorescent gene expression cell bioassay. The developed method allows for simultaneous gravimetric lipid weight dete

Chemo-enzymatic epoxidation of oleic acid (OA) and its methyl ester has been performed using hydrogen peroxide and immobilized lipase from Candida antarctica (Novozym(R) 435). The purpose of the study was to characterize the reaction under solvent-free conditions. The reaction temperature had a significant impact on epoxidation of OA. At lower temperatures, the substrate conversion was hindered by

The authors show a magnetoresistive effect that appears in a lithographically shaped, three-arm nanostructure fabricated from ferromagnetic (Ga,Mn)As layers. The effect, related to a rearrangement of magnetic domain walls between different pairs of arms in the structure, is revealed as a dependence of zero-field resistance on the direction of the previously applied magnetic field. This effect coul

This study investigates whether intravitreal administration of glial cell line-derived neurotrophic factor (GDNF) enhances survival of NeuN positive retinal cells in a porcine model of retinal ischemia. 16 pigs were subjected to an ischemic insult where intraocular pressure was maintained at 5 mmHg below mean arterial blood pressure for 2 h. The mean IOP during the ischemic insult was 79.5 mmHg (s

1 In a calcareous dry grassland community in central Europe genets of the clonal sedge Carex humilis form very distinct rings of densely aggregated ramets. As genet growth form is generated by ramet population dynamics, ramet demography must be studied in order to understand how rings develop. We analysed how ramet demography in C. humilis depends on ramet position within the ring and how this is

In this article it is shown how the tuning of a loop is used to commission a closed-loop performance monitoring method. The extended prediction horizon index is used to monitor disturbance rejection properties expressed with the impulse response. The impulse response is obtained from the tuning of the loop. All parameters of the monitoring method are set by using the impulse response. The presente

The influence of pH on the growth and assimilation of N-15-labelled ammonium and nitrate was studied in intact ectomycorrhizal systems consisting of Betula pendula Roth and Picea abies (L.) Karst. colonized with a common mycelium of Paxillus involutus (Batsch) Fr. The plants were grown together in Plexiglass observation chambers containing non-sterile peat with three different pH values, 4.0, 5.1

For photon fields, separate dose distribution kernels have been generated for charged particles produced in the first interaction, for single and multiple scattered photons, including bremsstrahlung and annihilation. These kernels are applied in absorbed dose calculations for radiotherapy treatment planning using a convolution technique. The vast amount of kernel data required for 3D calculations

Adsorption of Co(II) at the aqueous interfaces of ZnO and ZnS (wurtzite) has been studied by classical wet-chemical methods, and the structure and composition of Co adsorption complexes at these interfaces have been determined by in-situ X-ray absorption fine structure (XAFS) spectroscopy. On both adsorbents, adsorption as a function of pH shows the normal behavior, i.e., a pronounced adsorption w

Occasionally anaesthesiologists find themselves in situations where ventilation during intubation with a fibreoptic bronchoscope (FOB) is desirable. In order to ventilate the patient during the FOB intubation, we used a 90 degree angle swivel connector, normally used for fibreoptic bronchoscopia in an intubated patient. After a nasotracheal tube is placed with the tip in the oropharynx, ventilatio

Type 1 diabetes in Sardinia is very common in children, and we hypothesized that Latent Autoimmune Diabetes of Adult (LADA) might constitute a significant proportion of diabetes in adult Sardinian subjects. Since Type 2 diabetes is a familial disorder, we tested this hypothesis by investigating the prevalence of GAD65 and IA-2 autoantibodies (Ab) in Type 2 diabetes multiplex families of Sardinian

The authors compared how four indexes-the Healthy Eating Index-2005, Alternate Healthy Eating Index, Mediterranean Diet Score, and Recommended Food Score-are associated with colorectal cancer in the National Institutes of Health-AARP Diet and Health Study (n = 492,382). To calculate each score, they merged data from a 124-item food frequency questionnaire completed at study entry (1995-1996) with
