Membrane probe array: Technique development and observation of CO2 and CH4 diurnal oscillations in peat profile

The purpose of this study was to monitor the dynamics of gases such as CO2 and CH4 in a soil profile with sufficient temporal resolution to observe possible diurnal variations. A computer-controlled device called a membrane probes array (MPA) was developed that consisted of 9-12 individual membrane probes installed at various soil depths. Each probe was made of a stainless steel pipe with a 1 mm o

Ultrafiltration of bleach plant effluent

An up-to-date evaluation of capacity and retention of new membranes with regard to bleach plant effluents has been made. The results from a trial of seven reverse osmosis, ultrafiltration and microfiltration membranes are reported. The trial has even included membranes not yet commercially available. The trial has demonstrated that some of the tested membranes could probably combine a satisfactory

Detection of Mycobacterium tuberculosis complex in formalin-fixed, paraffin-embedded tissue specimens with necrotizing granulomatous inflammation by strand displacement amplification

Rapid, reliable diagnosis of tuberculosis is essential to initiate correct treatment, avoid severe complications, and prevent transmission. Conventional microbiological methods may not be an option if samples are formalin-fixed and paraffin-embedded (FFPE) for histopathological examination. With the demonstration of necrotizing granulomatous inflammation, tuberculosis becomes an important differen

Beräkning av inneklimat i luftvärmda rum

Denna rapport omfattar analys av klimat i rum som värms och ventileras med luftburen värme. Oberoende av utomhustemperatur och inre belastningsvariationer ska ett inomhusklimat åstadkommas som ger brukarna komfort i vistelsezonen. Syftet med arbetet är att ta fram en beräkningsmetod. Denna ska användas för att teoretiskt utreda om det finns någon donplacering som är bättre än andra ur termisk, hyg

Speech enhancement with natural sounding residual noise based on connected time-frequency speech presence regions

We propose time-frequency domain methods for noise estimation and speech enhancement. A speech presence detection method is used to find connected time-frequency regions of speech presence. These regions are used by a noise estimation method and both the speech presence decisions and the noise estimate are used in the speech enhancement method. Different attenuation rules are applied to regions wi

On the Use of Laser-Induced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines

The laser-induced incandescence technique (LII) is a laser-based diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. A theoretical model for LII has been implemented and improved in order to provide a tool for predicting the signal respons

Vagus nerve stimulation in 15 children with therapy resistant epilepsy; its impact on cognition, quality of life, behaviour and mood.

PURPOSE: Vagus nerve stimulation (VNS) is a neurophysiologic treatment for patients with refractory epilepsy. There is growing evidence of additional quality of life (QOL) benefits of VNS. We report the effects of VNS on seizure frequency and severity and how these changes are related to cognitive abilities, QOL, behaviour and mood in 15 children with medically refractory and for surgery not eligi

Percent-free prostate specific antigen is elevated in men on haemodialysis or peritoneal dialysis treatment.

Background: Men with chronic renal failure evaluated for transplantation are often tested for prostate specific antigen (PSA) to detect prostate cancer. PSA occurs in several different molecular forms in serum: free PSA (fPSA) and complexed PSA (cPSA), the sum of which corresponds to total PSA (tPSA). In addition to tPSA, percent fPSA to tPSA (%fPSA) is widely used to enhance discrimination of ben

Effect of cysteine mutations on direct electron transfer of horseradish peroxidase on gold

Surface exposed cysteines were genetically engineered in the structure of recombinant horseradish peroxidase (rHRP). Recombinant forms of HRP with either a His-tag or a Strep-tag at the C-terminus were produced, which additionally had cysteines at positions 57, 189 or 309 (C-terminus) of the polypeptide chain. An E coli expression system was exploited. The effect of these mutations on the direct e

Tron, ordet och nådegåvorna : en studie av Livets Ord i Tjeckien

In this thesis Word of Life (Slovo zivota) in the Czech Republic is studied from a sociological perspective with a special focus on the Swedish influence, especially the teachings of Ulf Ekman, on the Czech Word of Life-congregations. Another purpose is to examine if there also is space for domestic interpretations of the theology of the faith-movement and if there is any integration with Czech re
