1. 21. Xenobiotic-metabolizing enzymes and enzymes involved in the metabolism of reactive oxygen species in the porcine ovary : subcellular distributions and levels of expression during follicular maturation and in the non-pregnant and pregnant corpus luteum

   Författare :Maria Eliasson; Thomas Friedberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

   Sammanfattning : The polycyclic aromatic hydrocarbon (PAH) 7,12-dimethylbenz(a)anthracene (DMBA) is metabolized by both porcine ovarian microsomes and mitochondria, with the highest activity being seen in the corpus luteum. Microsomal DMBA monooxygenase activity is inhibited by inhibitors of the CYP450 system and by 17-bestradiol, thus indicating involvement of CYP1B1. LÄS MER

3. 22. Expressions of Future in Present-day English: A Corpus-based Approach

   Författare :Ylva Berglund; Merja Kytö; Michael Stubbs; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; English language; association patterns; corpus linguistics; English; expressions of future; tense; variation; Engelska; English language; Engelska språket;

   Sammanfattning : This corpus-based study of the use of expressions of future in English has two aims: to examine how certain expressions of future are used in Present-day English, and to explore how electronic corpora can be exploited for linguistic study.The expressions focused on in this thesis are five auxiliary or semi-auxiliary verb phrases frequently discussed in studies of future reference in English: will, ’ll, shall, going to and gonna.

4. 23. Understanding and enhancing translation by parallel text processing

   Författare :Magnus Merkel; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : In recent years the fields of translation studies, natural language processing and corpus linguistics have come to share one object of study, namely parallel text corpora, and more specifically translation corpora. In this thesis it is shown how all three fields can benefit from each other, and, in particular, that a prerequisite for making better translations (whether by humans or with the aid of computer-assisted tools) is to understand features and relationships that exist in a translation corpus.

5. 24. Resource Lean and Portable Automatic Text Summarization

   Författare :Martin Hassel; Hercules Dalianis; Viggo Kann; Kerstin Severinson Eklundh; Horacio Saggion; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; holsum; language independent; holistic; summarization; lexical semantics; co-occurrence statistics; word space model; bag-of-words; bag-of-concepts; random indexing; swesum; news corpus; extract corpus; Computer science; Datalogi;

   Sammanfattning : Today, with digitally stored information available in abundance, even for many minor languages, this information must by some means be filtered and extracted in order to avoid drowning in it. Automatic summarization is one such technique, where a computer summarizes a longer text to a shorter non-rendundant form. LÄS MER

7. 25. Blood flow and metabolism in the corpus luteum of the rat : in vivo and in vitro studies on the ovarian luteal and follicular compartment of the rat

   Författare :Mats Gåfvels; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovary; follicle; corpus luteum; blood flow; metabolism; luteinizing hormone; noradrenaline; antidiuretic hormone;

   Sammanfattning : The ovary undergoes cyclic changes in follicular growth and luteogenesis due to the action of gonadotropins and steroids. The ovary and especially the corpus luteum has an exteremely high blood flow. There is a gap in our knowledge about the physiological role of the high blood flow of the corpus luteum. LÄS MER
