This paper investigates the use of corpora, with a specific focus on concordances,in teaching and learning as a foreign language in classrooms in Vietnam. Students who used concordances obtained more correct answers than those who did not, and they could develop activeness in exploring words structures and grammatical rules.
Popular Abstract in Swedish I magtarmkanalen upptas ständigt nyttiga näringsämnen, men samtidigt avvisas skadliga bakterier, gifter och allergiframkallande ämnen. I avhandling beskrivs hur tarmens normala barriärfunktion hos råtta och gris kan förändras på konstgjord väg. I delarbete I har det normala flödet av enzymer från bukspottkörteln till tunntarmen stoppats för att studera dessa enzymers bThe gastrointestinal tract has two opposing functions; to absorb nutrients and electrolytes, and to act as a barrier towards hazardous and non-nutritional substances. In the present thesis the barrier function of the gastrointestinal tract was studied in animal models in vivo, in situ and in vitro. Experimentally induced disorders of the intestinal barriers were evaluated in terms of altered inte
This thesis describes the relations between objects, practices, and individuals. The main objective is to explore the role of artefacts in user-centred participatory design research, specifically for expressing and communicating personal experiences and creating meaning. In a broad sense I draw on experiences from three practices in order to define the scope of the thesis. The first is practice-le
Swedish patent nr 189939. "Anordning för alstring av ett artificiellt tröghetsmoment hos ett roterbart anordnat system". (Device for creating an artificial moment of inertia in a rotating system.) Co-inventor Folke Hector Philips. Granted January 16 1964. Patent also granted in England, France, Holland, Canada, Germany, USA, Austria, Japan. This patent describes a new way of implementing Schuler
It is proposed to capture localized plastic deformation via the inclusion of regularized displacement discontinuities at element boundaries (interfaces) of the finite element subdivision. The regularization is based on a kinematic assumption for an interface that resembles that which is pertinent to the classical shear band concept. As a by-product of the regularization, an intrinsic band width is
We consider a time-hopping impulse-radio system that uses transmitted-reference pulses for implicit channel estimation and equalization. A hybrid receiver structure first performs a filtering matched to the hopping sequence, and a subsequent correlation of the data pulses with the reference pulses. We analyze the performance of such a system both in AWGN and in multipath. For the AWGN case, we giv
