2. 1. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus

   Author : Karin Hjort; Patrick Dennis; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Cell cycle; Sulfolobus; Archaea; Origin; Replication; SIRV2; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; mikrobiologi; Microbiology;

   Abstract : The third domain of life, Archaea is one of the three main evolutionary lineages together with the Bacteria and the Eukarya domains. The archaea are, despite their prokaryotic cell organisation, more closely related to eukaryotes than to bacteria in terms of the informational pathways (DNA replication, transcription and translation).

4. 2. The green engineer as an enabler of life-cycle management in manufacturing: models and practices

   Author : Birger Löfgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete-event simulation; life-cycle assessment; operation management; decision making; practice studies; environmental management;

   Abstract : The last 20 years corporate environmental management has developed from pollution control and emission prevention, to include a greater responsibility for indirect environmental issues along the whole product life cycle. This thesis aims at providing a better understanding of how such environmental life-cycle management can be applied on manufacturing processes. READ MORE

5. 3. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle

   Author : Mats Walldén; Johan Elf; Peter Graumann; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; E.coli; cell cycle; replication initiation; transcription factor; gene-regulation; single molecule microscopy; microfluidics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

   Abstract : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. READ MORE

6. 4. Towards a framework for enabling sustainable production systems: a life-cycle perspective

   Author : Ilaria Giovanna Barletta; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; discrete event simulation; e-waste; KPI; triple bottom line; decision support; manufacturing; sustainability;

   Abstract : This thesis contributes to scientific knowledge by offering the foundation of a framework that helps stakeholders such as managers and engineers to enable sustainability over the entire lifecycle of the production system, from planning to re-use. In this thesis sustainability can be assessed through performance indicators and is understood through its triple bottom line of: economic, environmental and social sustainability. READ MORE

7. 5. On Discrete-Event Simulation and Integration in the Manufacturing System Development Process

   Author : Lars Randell; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; configuration management; discrete-event simulation; Production technology; Produktionsteknik; robotics; Automation; robotteknik; reglerteknik;

   Abstract : DES is seldom used in the manufacturing system development process, instead it is usually used to cure problems in existent systems. This has the effect that the simulation study alone is considered being the cost driver for the analysis of the manufacturing system. READ MORE
