A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test

The single-aliquot regenerative-dose (SAR) protocols used in retrospective dosimetry for optically stimulated luminescence measurements have been mainly developed for archaeological and geological dating of quartz and feldspar. The aim in this study is to find a read-out protocol that can generate the most reproducible signal for household salt (NaCl) at absorbed doses below 100 mGy. The relation

This paper questions assumptions about the importance of group processes for the learning outcome in PBL groups. It is argued that previous research has downplayed the occurrence and importance of such processes. Through an empirical study with collective Group Diaries in 12 PBL group of approx. 70 students over one term., the occurrence of 67 hindering incidents is demonstrated. The most frequent

A differential two-wire communication link with a 3-level asynchronous protocol is introduced. The proposed 3-level code contains information of both data and clock. Since only one edge is needed for each bit, the bandwidth of a link is efficiently utilized. The power consumption is reduced by the low-swing differential two-wire link and is further reduced by a 3-level code. The speed of the proto

OBJECTIVE: To explore the characteristics and outcome of patients after stroke admitted to early supported discharge (ESD) services, and to investigate changes over time. STUDY POPULATIONS: Patients admitted between June 1997 and September 1998 and participating in a follow-up study (n = 87) and all patients admitted in 2005-06 (n = 226). Background populations: All stroke cases in Malmö alive 3 m

The properties of the arterial vasculature depend to a large extent on the activities of smooth muscle cells, which, in turn, are determined by their extracellular environment. During pathological conditions, such as atherosclerosis, this interaction is altered. In close proximity to medial smooth muscle cells are basement membrane components, such as different isoforms of laminin. These proteins

Partial wh-movement does not exist in the modern Scandinavian languages. It is however found in Old West Scandinavian texts, but not in Old East Scandinavian texts. In this article it is argued that there is a correspondence between attested partial wh-movement and the possibility of deleting the complementizer corresponding to English that. Although complementizer deletion is possible in all mode

Microdosing is a new concept in drug development that-if implemented in the pharmaceutical industry-would mean that new drugs can be tested earlier in humans than done today. The human microdosing concept-or 'Phase 0'-may offer improved candidate selection, reduced failure rates in the drug development line and a reduction in the use of laboratory animals in early drug development, factors which w
