Bacterial abundance and production were studied in different zones in the Southern Ocean (39-62degreesS, 4-14degreesE) during a cruise in December-January 1997/1998. The role of potential growth limitation of bacteria due to limited availability of organic carbon (glucose) or inorganic N and P was studied in parallel. A positive correlation between surface water temperatures (-2 to 18 degreesC) an

Popular Abstract in Swedish Mineraler fås från både fast och flytande föda. De senaste årtiondena har bordsvattenkonsumtionen ökat, och vattnets kemiska innehåll har alltmer kommit i fokus. Studier visar dessutom att grönsakers mineralinnehåll har minskat, vilket ökar betydelsen av mineralintag från annat håll. Den här doktorsavhandlingen omfattar fyra olika studier. I den första studien undersökMineral elements in drinking water have been in focus for more than a decade, especially as the habit of drinking bottled water has increased, not the least among young people. Minerals in drinking water have become more important since minerals in food, especially in vegetables, have decreased substantially the last decades. This thesis includes four different studies. In the first study 20 munic

Popular Abstract in Swedish På grund av den förutspådda energi krisen som föranleds av att oljan tar slut, är det viktigt att söka efter alternativa energikällor. Att utnyttja solljuset via en artificiell fotosyntes är en intressant möjlighet. Det långsiktiga målet för forskning på detta område är att bygga molekylära och/eller fasta material som kan använda solljus för att dela vatten i dess bestDue to the predicted energy crisis when fossil fuels will be exhausted it is important to search for alternative energy sources. Utilizing sunlight via artificial photosynthesis is an interesting possibility. The long-term goal for research in this area is to design and build molecular and/or solid state systems that can use sunlight to split water and produce fuel (e.g. hydrogen). Nature tells us

Effects of ultraviolet (UV)-B radiation and acidification on pelagic carbon flux in a humic lake (dissolved organic carbon [DOC] similar to15 mg C L-1) were studied in a mesocosm experiment during the summer of 2000. Triplicate tanks (107 liters volume, 1 m high) were exposed to natural solar radiation, a daily extra dose of UV-B radiation, or kept dark. One set of tanks was submitted to a decreas

Traditionally used methods for developing a synthetic unit hydrograph (SUH) are well known for their limitations. In last few decades, use of probability distribution functions in developing SUHs has received much attention. In this study, the potentials of a three-parameter beta distribution are explored. Using a analogy between the three-parameter beta-distribution shape and the SUH shape, appro

The thesis examines various aspects of "electricity hypersensitivity" (EH). An empirical investigation of a group of persons suffering from EH was carried out, a part of the group being treated psychologically according to cognitive- behavioural principles in a controlled outcome study. The major findings concern an explanatory-model of EH, the the assessment of characteristics of EH-sufferers and

This book investigates the relationship between the quality of working life (QWL) and competitiveness in the specific context of organisational innovations in Sweden. It proceeds by way of reviewing the literature of both a general theoretical nature on innovations, including Swedish research, and then looks more closely at the empirical evidence on the QWL-competitiveness relationship at the micr

The quest of developing the logistics discipline, with a more theoretical foundation, is something several authors have emphasized and called for. Today one could argue that most of the research on logistics has a strong connection to the positivistic paradigm where there is a great emphasis on prediction, rationality and control in the solutions produced. In order to challenge the common assumpti

The study aimed at developing a process for making a wood coating wax based on the principles of green chemistry. The research was conducted within the Swedish interdisciplinary research programme Greenchem. Wax esters are attractive since they are non-hazardous, biodegradable and can be produced in an atom-efficient process from building blocks obtained from renewable resources. Four wax esters w

Addressing unsustainable consumption patterns is an important target for fulfilling the goals set in, among others, Agenda 21 and the United Nations Framework Convention on Climate Change. Gender differences in consumption patterns and their environmental impact have so far been poorly investigated. Gender differences in travelling patterns in Sweden are explored using data from the National Trav

Popular Abstract in Swedish Syftet med föreliggande arbete har varit att undersöka statusen på nygjort glasmåleri från 1851-1955. Utgångspunkten har varit att detta glasmåleri oftast inte förekommer i konstens allmänna historia, trots att välkända konstnärer faktiskt gjort glasmåleri. Ett viktigt metodiskt grepp har varit att undersöka statusfrågan utifrån uppfattningar om glasmåleriets mediespeci
