   Sammanfattning : Glass beads comprise the most frequently found evidence of trade between southern Africa and the greater Indian Oceanbetween the 7th and 16th centuries AD.  In this thesis beads recovered from southern African archaeological sites are organized into series, based on morphology and chemical composition determined by LA-ICP-MS analysis.

3. 2. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa

   Författare :Alexey Vorobyev; Kristofer Gamstedt; Eiichi Obataya; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; archaeological wood; compression test; cubic samples; elastic constants; oak wood; barrelling formation; quasi-static loading; resonant ultrasound spectroscopy RUS ; Vasa ship; creep; 3D laser scanning; Time-dependent behaviour;

   Sammanfattning : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. LÄS MER

4. 3. Sulfur-Related Conservation Concerns in Marine Archaeological Wood : The Origin, Speciation and Distribution of Accumulated Sulfur with Some Remedies for the Vasa

   Författare :Yvonne Fors; Magnus Sandström; Ian MacLeod; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sulfur accumulation; marine archaeological wood; Vasa; acidity; iron; ammonia; x-ray spectroscopy; cellulose; Chemistry; Kemi; strukturkemi; Structural Chemistry;

   Sammanfattning : Synchrotron-based sulfur spectroscopy reveals a common concern for marine archaeological wood from seawater: accumulation of reduced sulfur compounds in two pathways. The distribution of sulfur species in the oak wood cell structure was mapped by scanning x-ray spectro-microscopy (SXM). LÄS MER

5. 4. The Egyptianizing, male, limestone statuary from Cyprus : a study of a cross-cultural, Eastern Mediterranean votive type

   Författare :Fanni Faegersten; Antikens kultur och samhällsliv; []
   Nyckelord :HUMANIORA; HUMANITIES; ivory; cultural contacts; Egypt; Phoenicia; archaeological contexts; votive gifts; sanctuaries; the Archaic period; transformations of Egyptian dress and jewelry; Egyptianizing iconography; limestone; Cyprus; Cypriote sculpture; wood; “color as pattern”; royal iconography; Ancient history; Antikens och forntidens historia; Archaeology; Arkeologi;

   Sammanfattning : This thesis is a study of a particular limestone votive statuary type which was dedicated in the sanctuaries on Cyprus during the entire 6th century B.C. Common to the group of figures is that they are wearing a Cypriote version of an Egyptian-type outfit, including characteristic Egyptian royal headgear and jewelry. LÄS MER

7. 5. Mechanical behaviour of hardwoods : effects from cellular and cell wall structures

   Författare :Ingela Bjurhager; Lars Berglund; Ingo Burgert; Magnus Wålinder; KTH; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära;

   Sammanfattning : Syftet med den här avhandlingen var att undersöka mekaniska egenskaper hos olika arter av lövträd, och koppla egenskaperna till cell- och cellväggsstrukturen i materialet. Arterna som omfattades av undersökningen var Europeisk asp (Populus tremula), hybridasp (Populus tremula x Populus tremuloides) och ek (Quercus robur). LÄS MER
