The present thesis analyzes the reform of congregational singing in Livonia and Estonia in the first half of the 19th century. In this process the writings on the aesthetics of the congregational singing of a German pastor Johann Leberecht Ehregott Punschel (1778–1849) active in Livonia, and a chorale book (1839) that he edited occupied the central place. Punschel’s activities are directly associa
Popular Abstract in Swedish För att levande celler ska kunna föröka sig behöver förr eller senare celldelning ske. Detta är en process där en ny cell skapas utifrån den information som finnas lagrad i ursprungscellen. Denna typ av information lagras i cellens DNA. En stor del av DNA:t är ritningar för hur cellens arbetarmolekyler, proteinerna, ska byggas men DNA:t innehåller även information för rIt has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. RNRs carry out a key step in the de novo synthesis of building blocks for DNA and have been found in almost all known organisms. Within this th
Succinate:quinone reductase (SQR) is an enzyme in the respiratory system of aerobic cells. SQR catalyzes two reactions, the oxidation of succinate to fumarate and the reduction of quinone to quinol. These reactions are coupled by electron transfer within the enzyme from the site of succinate oxidation to the site of quinone reduction. Some enzymes reduce ubiquinone (exergonic reaction) whereas oth
Popular Abstract in Swedish Perifer kärlsjukdom (peripheral arterial disease) innebär ett tillstånd med nedsatt blodcirkulation i benen som huvudsakligen beror på åderförkalkning (ateroskleros). De kliniska manifestationerna av perifer kärlsjukdom är fönstertittarsjuka (claudicatio intermittens) och svår cirkulationsnedsättning (kritisk ischemi) beroende på om blodcirkulationen är otillräcklig vidPeripheral arterial disease (PAD) is the manifestation of atherosclerotic lesions in arteries supplying blood to the legs. Atherosclerosis is now recognized as an inflammatory disease of the vessel wall and important features in the pathophysiology are activation of WBC, endothelial cells and increased levels of inflammatory mediators. The inflammatory response in PAD is further influenced in case
A national debate about how to transform and to ‘green’ the problematic housing stocks from the boom era has been going on since the late 1990s. Different kinds of policy instruments with energy efficiency objectives that address either energy systems, energy sources or construction and renovation of the building envelope have been in use. Some policy instruments have combined green objectives wit
We minimize the frequency and time occupancy of multicarrier binary linear modulation based on two-dimensional faster than Nyquist (FTN) signaling. FTN analysis provides the asymptotic time–frequency consumption per bit and prolate spheroidal wave analysis minimizes the side lobe occupancy. For both problems, an excellent choice is a Gaussian pulse, with some adjustment of the side lobes.
Classifying images of HEp-2 cells from indirect immunofluorescence has important clinical applications. We have developed an automatic method based on random forests that classifies an HEp-2 cell image into one of six classes. The method is applied to the data set of the ICPR 2012 contest. The previously obtained best accuracy is 79.3% for this data set, whereas we obtain an accuracy of 97.4%. The
Popular Abstract in English Wild fruits trees species are widely distributed throughout the African countries. Many of these trees species produce fruits, which are used by the local communities to greater or less degrees. The importance of wild fruits in the diet depends to a large extent on the availability of the fruits, since cultivated fruit trees are not particularly common in the dry regionAbstract Wild fruit trees have significant cultural and socio-economic value in rural areas of Mozambique. Most of the wild fruits are seasonal and are available mainly in the wet season. Generally they have a short shelf-life and are eaten fresh or after minimal processing; the most common method of preservation is sun-drying. The fruits of Adansonia digitata, Landolphia kirkii, Salacia kraussii,
