Mammalian melanins are of two major types, eumelanins and peheomelanins, which often occur together, then called mixed-type melanins. A method has been developed for analysing the various forms of melanins. Melanin characterisation included their oxidation in permanganate under alkaline conditions, and analysis of the resulting degradation products, pyrrole-2,3,5-tricarboxylic acid (PTCA), pyrrole
In this paper, an algorithm for projective reconstruction of general 3D-curves from a number of its 2D-images taken by uncalibrated cameras is proposed. No point correspondences between the images are assumed. The curve and the view points are uniquely reconstructed, modulo projective transformations. The algorithm is divided into two separate algorithms, where the output of the first is used as i
Nineteen species of the genus Caloplaca from Australia are described and illustrated: eight species (namely: C. bermaguiana, C. conranii, C. filsonii, C. gallowayi, C. kiamae, C. eos, C. tomareeana and C. whinrayi) mainly occur in coastal localities; further eight species (C. aliciae, C. astonii, C. australiensis, C. haematommona, C. marchantii, C. montisfracti, C. rheinigera, and C. streimannii)
This chapter argues for the importance for basic areas knowledge in group psychology as prerequisites for supervisors working in group formats. The tasks of the supervisor are divided into a) task related work, b) maintenance work, c)individuallly oriented work and d) organizational work. The unique charactistics of supervision groups are discussed. A number of useful models concerning group forma
By using examples of European meetings with indigenous Mi‟kmaq in the Atlantic provinces of Canada in the early 17th century, I will show how the concept of wilderness was employed as a key metaphor for establishing the moral right and duty of Europeans to colonize the land, reorganizing the nomadic hunters in settled communities and remaking the mobile nature of the “savage” in the image of a cul

The technical development in complex and highly automated production processes affects the process operator’s work and the demands on the operator. Two significant problems are difficulties in acquiring and maintaining the necessary competence and a risk of understimulation, since a stable process does not generate many active tasks, largely because of a higher degree of automation. In this case s
Ecologists have often compared ecological communities in different areas, for example on different continents. The main interest is that the communities might be more similar in the characters of their species than expected under a null model of random species assortment. We suggest that such a null model should be based only on the species observed across the samples. Species-level convergence an
In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. Two types of failure management strategies can be applied: proactive asset condition assessment and reactive failure detection and location. Currently available con
