Thermostimulated and photostimulated luminescence of ZnWO4, ZnWO4:Fe and ZnWO4:MO Crystals irradiated at low temperatures by X-rays or UV photons was studied in the temperature range 4.2-300 K in order to clarify the creation and recombination processes of the elementary colour centres. The connection of the luminescence phenomena with the self-trapped holes has been revealed. (C) 2003 Published b

Objectives: To investigate whether postural stability and adaptation differed after a normal night of sleep, after 24 h (24 SDep) and 36 h (36 SDep) of sleep deprivation while subjected to repeated balance perturbations. Also, to determine whether there was any correlation between subjective alertness scores and objective posturographic measurements. Lastly, to investigate the effects of vision on

We consider a class of distributed algorithms for computing arithmetic averages (average consensus) over net- works of agents connected through digital noisy broadcast channels. Our algorithms combine error-correcting codes with the classical linear consensus iterative algorithm, and do not require the agents to have knowledge of the global network structure. We improve the performance by introduc

Detta är HHLs första publicerade alster, som siktar till en utvecklad diskussion om hur det svenska frihandelsavtalet med EEC kan tänkas komma att fungera i praktiken. I första hand är det frihandelsavtalets artikel 23 med konkurrensbegränsningsregler som lyfts fram. Bestämmelsen saknar direkt effekt, men vad innebär det att gemenskapen gjort en tolkningsförklaring om att bestämmelsen ska tolkas e

Since the energy required in the paper drying process gives rise to substantial costs for the paper producing companies, it is of great interest to reduce the input of primary energy resources to the dryer. Either process changes or further heat recovery can be employed. A simulation tool was developed, using the programming tool Extend, with the aim to accurately describe the energy use and costs

In the bottom - a well with finds: Popular presentation of the excavation and medieval finds from Baglergatan 10, Tønsberg, Norway.

The study of the composition of the Book of Psalms has gained much scholarly attention since the groundbreaking dissertation by Gerald H Wilson in 1985. One of the clearest signs of redaction was the addition, or use, of four doxologies in Pss 41, 72, 89 and 106. They all share a number of features, but not two are identical. As they are considered to belong to the very latest stages of redactiona

Popular Abstract in Swedish I avhandlingsarbetet har spridning av förorenad jord till följd av jordskred till ytvatten studerats genom att sammankoppla faran för miljö och hälsa från förorenad mark med faran för skred. Skredriskbedömningar görs på många håll runt om i världen, likaså riskbedömning av förorenad jord, dock görs dessa helt separerade från varandra och det finns därför väldigt lite inLandslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independ
