Cryogels as Solid Supports in Bioprocessing

In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. With the emergence of recombinant DNA technology, today m

Polysemy or generality? Mu

This chapter proposes a conception of lexical meaning as use-potential, in contrast to prevailing atomistic and reificational views. The issues are illustrated on the example of spatial expressions, pre-eminently prepositions. It is argued that the dichotomy between polysemy and semantic generality is a false one, with expressions occupying points on a continuum from full homonymy to full monosemy

Bacterial and fungal growth in soil: The effect of temperature and substrate addition

Bacteria and fungi are the main agents in decomposition of soil organic matter. Their activity is determined by the availability and quality of substrate, especially its content of carbon, but also nitrogen and phosphorus. Other environmental factors, which affect the activity of the microbial community in soil, are temperature, moisture and pH. In this thesis the focus was on how temperature and

Effects of cobalt and humic substances on the growth of bloom-forming marine phytoplankton

In this thesis, the importance of cobalt and humic substances of terrestrial origin for the growth of some bloom-forming marine phytoplankton species is examined. Cobalt (Co) is considered an essential and potentially limiting trace metal for phytoplankton growth and is needed for the synthesis of vitamin B12. Since Co can be mobilised from soils at low pH values, acidification may have led to an
