Validation of 3d finite element models from simulated Dxa images for Biofidelic simulations of sideways fall impact to the hip

Computed tomography (CT)-derived finite element (FE) models have been proposed as a tool to improve the current clinical assessment of osteoporosis and personalized hip fracture risk by providing an accurate estimate of femoral strength. However, this solution has two main drawbacks, namely: (i) 3D CT images are needed, whereas 2D dual-energy x-ray absorptiometry (DXA) images are more generally av

The Effect on Room Acoustical Parameters Using a Combination of Absorbers and Diffusers : An Experimental Study in a Classroom

Several room acoustic parameters have to be considered in ordinary public rooms, such as offices and classrooms, in order to present the actual conditions, thus increasing demands on the acoustic treatment. The most common acoustical treatment in ordinary rooms is a suspended absorbent ceiling. Due to the non-uniform distribution of the absorbent material, the classical diffuse field assumption is

Pragmadialektiikan maailmanvalloitus alkoi kaksikymmentäviisi vuotta sitten. Tänään se on yhtä tunnettu kuin jo viisikymmentä vuotta täyttäneet Toulminin ja Perelmanin uraauurtavat argumentaation teoriat. Arviot pragmadialektiikasta kuitenkin vaihtelevat huomattavan paljon. J. Anthony Blair on esimerkiksi luonnehtinut sitä maailman tärkeimmäksi argumentaation teoriaksi tänä päivänä. John Woodsin m

Replacing eye trackers in ongoing studies : A comparison of eye‐tracking data quality between the Tobii Pro TX300 and the Tobii Pro Spectrum

The Tobii Pro TX300 is a popular eye tracker in developmental eye-tracking research, yet it is no longer manufactured. If a TX300 breaks down, it may have to be replaced. The data quality of the replacement eye tracker may differ from that of the TX300, which may affect the experimental outcome measures. This is problematic for longitudinal and multi-site studies, and for researchers replacing eye

Astrocytic and Neuronal Apolipoprotein E Isoforms Differentially Affect Neuronal Excitability

Synaptic changes and neuronal network dysfunction are among the earliest changes in Alzheimer’s disease (AD). Apolipoprotein E4 (ApoE4), the major genetic risk factor in AD, has been shown to be present at synapses and to induce hyperexcitability in mouse knock-in brain regions vulnerable to AD. ApoE in the brain is mainly generated by astrocytes, however, neurons can also produce ApoE under stres

Cryptographic protection of usage restrictions in electronic devices

An electronic device requires valid control keys to change any usage restriction setting. The device is provided control keys, a secret key, and a signed software object including a batch ID and a hash of the secret key. For each control key, the device generates a cryptographic footprint bound to the device and the secret key. A message authentication code (MAC) of each usage restriction setting

Decreased phenolic defence in dwarf birch (Betula nana) after warming in subarctic tundra

Dwarf birch (Betula nana L.), a dominant deciduous dwarf shrub in many tundra ecosystems, is predicted to increase substantially in abundance due to climate warming. Potential warming-induced changes in the concentrations of phenolic compounds in B. nana leaves could influence the susceptibility of B. nana to environmental stresses; however, only a few studies have investigated the effects of clim

Grazing in Arctic peatlands - an unknown agent in the global carbon budget

Previous studies have offered strong evidence that grazers alter the vegetation composition and ecosystem carbon (C) balance in ecosystems. In Arctic peatlands, however, the role of grazing has remained largely uninvestigated. Falk et al (2015 Environ. Res. Lett. 10 045001) showed that grazing by muskoxen in a high Arctic mire significantly affected both the vegetation and release of greenhouse ga

Consequences of warming on tundra carbon balance determined by reindeer grazing history

Arctic tundra currently stores half of the global soil carbon (C) stock. Climate warming in the Arctic may lead to accelerated CO 2 release through enhanced decomposition and turn Arctic ecosystems from a net C sink into a net C source, if warming enhances decomposition more than plant photosynthesis. A large portion of the circumpolar Arctic is grazed by reindeer/caribou, and grazing causes impor

The effect of free convection on apparent vitamin degradation kinetics

Experimentally determined vitamin degradation kinetic parameters are vital input for process optimization, e.g., of nutrient rich beverages such as milk and fruit juices. The standard method of obtaining these parameters is to subject a test-tube of the nutrient (in its food matrix) to a water bath at elevated temperatures and measure remaining concentration as a function of time. It is well known

Outcome data from >10 000 multiple myeloma patients in the Danish and Swedish national registries

Objective: We describe real-world evidence (RWE) from the nationwide Swedish and Danish registries that provide important information on incidence and outcome in multiple myeloma (MM). Method: First line treatment data on more than 10.000 MM patients from Denmark and Sweden between 2005–2018 are presented. Key results from research conducted within the Swedish and Danish myeloma registries are sum

Hur har andrahandslägenheter i Malmö kommun fördelats till hemlösa över tid? : En studie av prioriteringar och exkluderingar

Under 1980-talet började flera svenska kommuner etablera en sekundär bostadsmarknad, där socialtjänsten hyrde ut lägenheter i andra hand till hemlösa klienter som var utestängda från den ordinarie bostadsmarknaden. Orsaken var en kombination av fastighetsägares ”höga trösklar”, socialtjänstens behov av boenden för hemlösa klienter och båda parters strävan efter kontroll. Möjligheten att tilldelas

Suppression of alkalization in rainwater regulating reservoir by shading on a pilot scale

As water in a rainwater regulating reservoir at the Sankyo landfill site in Nagasaki City tends to be alkalized and to exceed the pH upper limit of 7.5, measures to suppress the alkalization should be implemented. Inhibiting photosynthesis in algae is required to suppress the alkalization. Shading is one of the methods for inhibiting algal photosynthesis. In this study, we evaluated the pH reducti

Perceptions of participation and the role of gender for the engagement in solar energy communities in Sweden

Energy communities are emphasized by the EU as important for developing sustainable energy systems that include and engage many people. While many renewables are highly compatible with a more decentralized energy system, research indicates that participation in 'desirable' energy activities and energy decision-making is influenced by social and economic factors, including gender, economic status a

Loading data onto an electronic device

A method of protecting an electronic device from unauthorized reprogramming, the electronic device comprising a data memory and a key memory, the method comprising loading into the key memory a predetermined public key of a cryptographic public key mechanism for verifying subsequent data items to be loaded into the data memory, the subsequent data items being signed with a corresponding private ke

A Retardation Factor Considering Solute Transfer Between Mobile and Immobile Water in Porous Media

In advective-dispersive simulations of aquifers, retardation factors using linear adsorption isotherms are commonly employed to represent the adsorption-desorption process for solutes in soil. In particular, the retardation factors that use entire pore space (total porosity) or effective pore space (effective porosity) are widely used. Although another retardation factor that describes solute tran
