The ability to identify craft specialization in the archaeological record has wider ramifications for the study of prehistoric society, since it is apparent that there is a certain relationship between the organization of craft specialization and social complexity. It is fruitful to distinguish among 3 categories here: household production on the one hand, and attached and independent craft specia
Popular Abstract in Swedish Organiskt kol och mikroorganismer har ofta en mycket hög spatiell variation i jorden. Dessutom är mikroorganismer ofta begränsade av mängden kol även om detta beror på den den relativa koncentrationen av kväve, fosfor och organiskt kol i systemet. Man kan dock anta att mikroorganismers biomassa och aktivitet kan samvariera med halten organiskt kol i jordar som har en föOrganic carbon and bacteria have a high variability at different scales in the soil, and organic carbon may be a limiting factor for growth of soil bacteria. Thus, it can be expected that these co-vary at different scales in the soil. In this thesis, I have studied the spatial interaction between soil bacteria and natural and contaminant (polycyclic aromatic hydrocarbon, PAH) organic carbon. The o
The content of the European research project MAnaging Speeds of Traffic on European Roads (MASTER) is presented. Speed management is described as a two-step process where target speeds for different kinds of roads are determined first, and then various measures and tools are applied in order to adopt such speed. Current practice and main problems in speed management are described. The various impa
The present report gives a general discussion of typical behaviour and modelling concepts used in soil mechanics. Characteristic mechanical features for friction materials, such as stress state dependency, nonlinearity, dilation and anisotropy, are discussed as well as the factors affecting such features. A short overview of existing model concepts used in soil mechanics is presented. Various appr
"Zalmoxis" is a dramatic poem in which each character autonomously structures his own discursive lyric, expressing thus a variety of concepts over the spiritual foundation of the Dacians. The charm of each nuance in part relates in the last instance, the mode in which the author understands the proper structure of the actual dramatic perspective above the revolt of our non-Latin foundation. The ne
