Ambient solar radiation effects on Phragmites australis leaf and culm litter were investigated in a shallow and eutrophic south Swedish lake littoral. Leaf and culm litter was exposed to natural sunlight in the lake at a water depth of a few centimeters. For the leaf litter, an additional subset of the experiment was exposed to solar radiation in the air, to evaluate effects of the solar radiation

A fully integrated clock generator with behaviour similar to a PLL is proposed. A free-running ring oscillator is used as internal clock and the output clock is generated using two counters. The clock generator is described in synthesisable VHDL-code and can therefore easily be made from standard cells found in any commercial standard CMOS cell library.

The composition of cultivation media in relation to strain development for industrial application is reviewed. Heterologous protein production and pentose utilization by Saccharomyces cerevisiae are used to illustrate the influence of media composition at different stages of strain construction and strain development. The effects of complex, defined and industrial media are compared. Auxotrophic s

A (polysaccharide-rich) waste stream derived from a combined starch and ethanol factory was investigated regarding hydrolysis of the nonstarch carbohydrates for ethanol production. The material was characterized and processed to yield the maximum amount of sugars. The starch fraction was hydrolyzed with amylolytic enzymes, and the resulting fibrous material was separated by filtration. This materi

Patient associations for cancer patients (PACPs) are increasing in number as well as in the number of members. We utilised a questionnaire to investigate how members of 13 PACPs motivated their memberships. The study included 1,810 individuals who had been treated for breast cancer, gynaecological cancer, or prostate cancer. Through questionnaires these individuals were asked to articulate why the

The Gaussian curvature of a two-dimensional Riemannian manifold is uniquely determined by the choice of the metric. The formulas for computing the curvature in terms of components of the metric, in isothermal coordinates, involve the Laplacian operator and therefore, the problem of finding a Riemannian metric for a given curvature form may be viewed as a potential theory problem. This problem has,

I denna rapport behandlas uppvärmning med golvvärme och hur man med datorns hjälp kan reglera ett golvvärmesystem. Rapporten innehåller också en beskrivning av olika golvvärmesystem, främst vattenburen golvvärme, samt hur värmeförlusterna i en byggnad påverkas med golvvärmesystem. De reglerprinciper som behandlas i detta arbete är framkoppling från utetemperatur, återkoppling från innetemperatur o

An obese patient with type 2 diabetes whose diet was changed from the recommended high-carbohydrate, low-fat type to a low-carbohydrate diet showed a significant reduction in bodyweight, improved glycemic control and a reversal of a six year long decline of renal function. The reversal of the renal function was likely caused by both improved glycemic control and elimination of the patient's obesit

Intrapartum death has become a rare event since the introduction of electronic fetal monitoring (EFM). Randomized studies of EFM versus intermittent auscultation show that EFM reduces the risk of low Apgar score at birth and of neonatal seizures, although it may be possible to ensure low perinatal mortality even with intermittent auscultation alone. The rate of operative deliveries may increase wi

Occurrences of fire ignitions in a given region during a specified period of time are modelled as outcomes of a Poisson point process. The ignition frequency is considered a function of the total floor area of the building. Parameter estimates and their uncertainties are computed. Different criteria for model selection are used. The proposed methodology is specifically useful in the case with smal
