  1. 36. Improving energy efficiency in logistics systems: On the road to environmental sustainability

    Författare :Jessica Wehner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road freight transport; service modularity; service logic; logistics fulfilment; Capacity utilisation; point of consumption; first mile; service blueprint; household waste; distribution structure; system levels; systems perspective; value co-creation; last mile;

    Sammanfattning : Logistics are essential to efficiently managing the flow of materials and products between various nodes that operate in multiple systems. In that process, the activities of moving and storing materials and products, especially through road freight transport, consume significant energy resources and emit greenhouse gases that harm the environment.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; FeTi70R alloy; non-metallic inclusions; inclusion distribution; clusters; electromagnetic and gas stirring; ladle treatment; electrolytic extraction; stirring directions; Alloy 825; FeTi70R legering; icke-metalliska inneslutningar; inneslutnings fördelning; kluster; elektromagnetisk och gas omrörning; skänkugnsbehandling; elektrolytisk extraktion; omrörningshåll; Metallurgical process science; Metallurgisk processvetenskap; Steel Forming and Surface Engineering;

    Sammanfattning : It is well known that inclusions affect the properties of steels and alloys. Therefore, it is important to understand what type of inclusions that exist and how they behave and especially with a focus on large size inclusions. LÄS MER

  4. 38. Characteristic of Surge Transfer Through Transformers : Study of Conventional Distribution Transformer and XLPE Cable Winding Transformer (Dryformer)

    Författare :Mighanda Manyahi; Vladmiir Rakov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Sammanfattning : Wide spread application and dependence on microelectronics based equipment in modern society has necessitated the study of power supply quality problems in low voltage power installations. In spite of improvements in surge protection, sensitive equipment connected to low-voltage side of distribution transformer has continued to fail due to transient voltages that are transferred through distribution transformer from high voltage circuits.

  5. 39. Topographical study of intranuclear distribution and compartementalization of viral and cellular proteins

    Författare :Wei-Qin Jiang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nuclei of eukaryotic cells contain a number of specialized domains involved in DNA replication, transcription, pre-mRNA splicing and ribosome assembly. In addition to these structures, nuclear bodies of unknown function have been described. LÄS MER

  7. 40. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices

    Författare :Sebastian Franco Tabares; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; translucent; yttria; air-borne particle abrasion; 10-MDP; cement;

    Sammanfattning : New zirconia formulations (4Y and 5Y-zirconias) have been introduced for prosthodontic therapy and are commercialized as “translucent” zirconias. No clinical information providing their survival rates or complications has been provided to the date. LÄS MER
