It is investigated how the erasure efficiency for a single bit of data, stored using photon echoes, depends on the data writing time and data storage time. A comparative analysis of the erasure efficiency using a Ti:S laser system and a ring dye laser system is performed. The results clearly establish that the Ti:S laser system, which has a narrower line width than the dye laser system, could be u

This paper presents a computerized grammar which can analyze and generate a sample of pedagogical Chinese sentences, in particular those mentioned in the textbook Kinesiska är inte svårt (‘Chinese is not difficult’) by Göran Malmqvist 1974. Equivalent grammars for English and Swedish have also been constructed allowing translation between the three languages. The grammar model used is the Swetra g

The Gothic Maze focuses on the vigorous building activity among the 2,692 parish churches in medieval Denmark in the time up to the Reformation: Was this an expression of economic prosperity, increased piety, or a church in crises? Can the development be described as a transition from Romanesque to Gothic? How did the churches change? What was the economic background? Who were the benefactors? Wha

BACKGROUND: A large number of people throughout the world have diabetes and the prevalence is increasing. Persons with diabetes have a twice higher risk of cardiovascular disease than those without diabetes. There is a lack of studies focusing on cardiovascular risk factors in Assyrians/Syrians with type 2 diabetes. The aim of this study is to estimate the prevalence of some cardiovascular risk fa

This paper focuses on the grammatical expression or ‘packaging’ of modality in Japanese. I consider two aspects: (1) the grammatical encoding of epistemic, deontic, and evidential notions with English as a point of comparison, and (2) the co-encoding of modality and subjectivity. As for the former aspect, the comparison between Japanese and English exemplifies how languages can take different stra

This article address the means by which early followers can exert influence within a new religious movement. The case study that is used to exemplify potential dynamics in such a situation is that of the MOVE Organization, a group founded in the early 1970s in Philadelphia, Pennsylvania by a man known as "John Africa". Instead of focusing on the founder, however, this article examines the role pla

STUDY DESIGN: A thematic review. OBJECTIVES: To evaluate if physical activity enhances muscle strength, improves balance, and reduces the fall frequency and the fracture incidence. BACKGROUND: One of the major medical problems of today is the increasing incidence of fragility fractures. Muscle strength and fall is one of the major determinants of a fracture. If physical activity could increase mus

. Smärta efter stroke kan vara av olika typer och varierande svårighetsgrad . Personer med kommunikationsproblem kan behöva peka ut områdett för smärtan och med ansiktsuttryck visa hur svår smärtan upplevs eller ange smärtnivå på en skala.

The change of specific surface area and pore size distribution due to carbonation of an ordinary Portland cement mortar is investigated. The adsorption of water vapor on noncarbonated and well-carbonated cement mortar is measured in order to evaluate the difference in specific surface area for the two samples using the BET theory. From the measured desorption the pore size distribution is calculat

Extracellular matrix, either produced by cancer cells or by cancer-associated fibroblasts, influences angiogenesis, invasion and metastasis. Chondroitin/dermatan sulfate (CS/DS) proteoglycans, which occur both in the matrix and at the cell surface, play important roles in these processes. The unique feature that distinguishes DS from CS is the presence of iduronic acid (IdoA) in DS. Here, we repor
