Knee-extension strength, postural control and function are related to fracture type and thigh edema in patients with hip fracture.

BACKGROUND: Post-surgery thigh edema, loss of knee-extension strength, and reduced physical performance are common following a hip fracture. It is not known if knee-extension strength and physical performance are related to the edema and fracture type. The aim of this study was to examine the influence of fracture type and post-surgery edema on physical performances in patients with hip fracture.

Situated probing

In this position paper we present methodological considerations from a project in which we have collaborated with people with cognitive difficulties and university students. For people with considerable difficulties in communicating, a new means of expressing their dreams was required. Cultural probes were used to inspire, inform and surprise in the design process: situated probing.

Dispelling the myths about consumption behaviour

It has been acknowledged that the shift to more sustainable consumption patterns and levels is a complex task that requires the involvement of multiple societal actors and clear visions of more sustainable lifestyles. In addition to the complex nature of the problem and the diversity of interest of different actors with regard to their role in facilitating the change, there are also a number of my

Plant Major Intrinsic Proteins - natural variation and evolution

Popular Abstract in Swedish Livets minsta beståndsdel, cellen, omges av ett membran som avgränsar den från omvärlden. För att hålla den inre miljön kontrollerad måste cellen kunna styra transporten av olika ämnen över membranet, vilket görs med hjälp av olika proteiner. Dessa proteiner kan antingen vara energikrävande pumpar och transportörer som aktivt förflyttar substanser över membranet, eller Major Intrinsic Proteins (MIPs, also called Aquaporins, AQPs) are channel forming membrane proteins. Although initially functionally characterized and named after their water channeling property in human red blood cells, it has become increasingly evident that MIPs are present in all types of organisms and transport a variety of small, uncharged molecules besides water. MIPs have a highly conserve

A new approach to pipeline FFT processor

A new VLSI architecture for a real-time pipeline FFT processor is proposed. A hardware-oriented radix-22 algorithm is derived by integrating a twiddle factor decomposition technique in the divide-and-conquer approach. The radix-22 algorithm has the same multiplicative complexity as the radix-4 algorithm, but retains the butterfly structure of the radix-2 algorithm. The single-path delay-feedback a
