Electricity bought and sold on the deregulated Nordic power market is dominated by hydro power. However, hydro power generation is restricted by the amount of water in reservoirs. The inflows to these reservoirs show a yearly cycle and seasonal planning of the production is necessary. Seasonal planning up to 1.5 years for a power producer in a hydro-thermal system with a regulated river is consid

Solitary-wave solutions of a nonlinearly dispersive equation are considered. It is found that solitary waves are peaked or smooth waves, depending on the wave speed. The stability of the smooth solitary waves also depends on the wave speed. Orbital stability is proved for some wave speeds, while instability is proved for others.

Purpose: To suggest a more precise tool when assessing the risk of contrast-medium-induced nephropathy (CIN), i.e. the ratio between contrast medium (CM) dose expressed in grams of iodine (g-I) and estimated glomerular filtration rate in ml/min (eGFR; based on equations using serum-creatinine (s-Cr), weight, height, age, and/or sex), here named I-dose/GFR ratio. Material and Methods: A Medline sea

Proceeding from the assumption that metaphors as well as pictures are iconic signs, the present contribution studies what happens when metaphors occur in figurative pictures. The author distinguishes between primary iconicity, the recognition of which is a condition for the categorization of an object as a sign, and secondary iconicity, which is perceived only after an object has been categorized

Objective: To develop core recommendations for the learning outcomes of an undergraduate curriculum in musculoskeletal conditions for any parts of the globe. Methods: Recommendations were developed by wide consultation with experts in orthopaedics, rheumatology, osteoporosis, and rehabilitation from all parts of the world who had interest and experience in these specialties, with the support of in

In this study of the transfer function of copies of the Vienna-type differential mobility analyser (DMA) it was found that three, supposedly identical, DMAs exhibited distinct differences with respect to the width of the transfer function. This means that the transfer function of a DMA needs to be determined on an individual basis in order to obtain accurate results from DMA measurements. The size

The enzymatic and bioelectrocatalytic activity of tyrosinase from mushrooms was studied in a system of reversed micelles formed by Aerosol OT (AOT) in hexane. The optimal catechol oxidising activity of tyrosinase incorporated in reversed micelles was found at a hydration degree of w(0) = 25. The catalytic activity was comparable with tyrosinase activity in aqueous media. When immobilized at an Au

During two consecutive years 607 individuals with lower limb fractures were diagnosed. Half of the individuals, 315, were women and only 14 of them had an earlier registration for alcoholism. In the 292 men, however, 73 men or 25%, had been registered at the Department of Alcohol Diseases at least once during the 13 years of observation, the highest registration frequency (30%) was noted in the ma

Reaction of [MoO2(acac)(2)] with Li2NS2S'(2), (S is a thioether, S' a thiophenolate function) yielded the compound Li-7(thf)(17){MoO}(8)center dot 10thf center dot hexane, where {MoO}(8) represents one [(MoO)-O-IV(NS2S'(2))] 1, three [(MoO)-O-III(NS2S'(2))](-) (2, linked, via the oxo group, to [Li(thf)3](+)) and two [(MoO)-O-V(S'(2))(2)](2-)(2) .A mixed-valent variant of 3, [{(MoO)-O-IV(S'(2))} {(

Purpose: To describe the clinical and electrophysiological findings in a young boy with decreased vision possibly due to retinal damage by rifabutin. Methods: An 8-year-old boy with osteomyelitis was referred due to visual disturbance. During a period of 4 years, the boy was examined six times with electroretinography. Ophthalmological examination included testing of visual acuity, slit-lamp inspe

Photodynamic therapy (PDT) for the treatment of prostate cancer has been demonstrated to be a safe treatment option capable of inducing tissue destruction and decreasing prostate specific antigen (PSA) levels. However, prostate-PDT results in large intra- and interpatient variations in treatment response, possibly due to biological variations in tissue composition and short-term response to the th

A comparison of the absorption in paper of radiation from different IR sources has been made based on a theoretical model. As a first approach, blackbody spectra at 1300 K and 2500 K were compared. The radiation from the body at 1300 K is more readily absorbed by the paper There is, however only a small difference in the in-depth absorption when the intensities are adjusted to give the same amount

The background pattern in single channel amplitude integrated EEG recordings (aEEG) was recorded in 47 infants within the first six hours after birth to see if this could predict outcome after birth asphyxia. The aEEG background pattern during the first six hours of life was continuous and of normal voltage in 26 infants. All these infants survived; 25 were healthy, one had delayed psychomotor dev

We present experimental and DFT-simulated STM images of ultrathin RuO2(110) films on Ru(0001), including adsorbates such as oxygen and CO. We are able to identify the under-coordinated O atoms on the RuO2(110) surface with STM, i.e. the bridging O atoms and the on-top O atoms. The partial reduction of the RuO2(110) surface by CO exposure at room temperature leads to a surface where part of the bri
