Here we present a method for high-precision drilling using an industrial robot with high-bandwidth force feedback, which is used for building up pressure to clamp up an end-effector to the work-piece surface prior to drilling. The focus is to eliminate the sliding movement (skating) of the end-effector during the clamp-up of the end-effector to the workpiece surface, an undesired effect that is du

A kinematic hardening plasticity model valid for finite strains is presented. The model is based on the well-known multiplicative split of the deformation gradient into an elastic and a plastic part. The basic ingredient in the formulation is the introduction of locally defined configurations - center configurations- which are associated with deformation gradients that are used to characterize the

Popular Abstract in English Low fuel consumption, and reduced exhaust emissions, as well as improved performance and durability become much more important than before for the vehicle industry. These requirements lead to a number of additional equipment installed in the vehicles. All these efforts increase the operating temperature in the engine compartment and reduce the available free space in thCross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles. Placing the heat exchanger on the roof or at the underbody of vehicles might offer opportunity to increase the size o

Denna studie har gjorts med anslag från Statens Råd för Byggnadsforskning. Problemet har föreslagits av professor Bergström, LTH, som under arbetet givit många goda råd och annan hjälp. Vid betonggjutning vintertid skall man undvika att det börjar frysa i betongen innan denna har hunnit hårdna tillräckligt. Det ar då av intresse att kunna förutsäga temperaturförloppet i betongen under olika betin

Disturbed cellular cholesterol homeostasis may lead to accumulation of cholesterol in human atheroma plaques. Cellular cholesterol homeostasis is controlled by the sterol regulatory element-binding transcription factor 2 (SREBF-2) and the SREBF cleavage-activating protein (SCAP). We investigated whole genome expression in a series of human atherosclerotic samples from different vascular territorie

SUMMARY AT A GLANCE: Secretory leukocyte proteinase inhibitor (SLPI) is a major anti-elastase barrier at the epithelial surfaces of upper respiratory tract. Our findings indicate clear up-regulation of SLPI in response to endotoxin in nasal secretions. In addition, SLPI shows dose-dependent anti-apoptotic and chemotactic effects on primary human neutrophils. ABSTRACT: Background and objective: The

Physical workload was recorded by electromyography, inclinometry and goniometry for twelve female dental hygienists during authentic work. Their work was, in relation to other types of work, characterised by pronounced head flexion (90th percentile 46°), high loads on the forearm extensor muscles (90th percentile 23% and 18% of maximal EMG (MVE), for the right and left sides, respectively), averag

När en väljare röstar med andras beteende i åtanke och politikutfall i sikte är det en "strategisk" röst. Den här studien relaterar väljares strategiska överväganden till olika steg i regeringsbildningsprocessen: att ta plats i parlamentet, ingå i regering, och påverka politikutfallet. Detta innebär att väljaren ibland tänker som ett parti på vad rösten kan få för konsekvenser. Utifrån detta perspIf a voter defects from preference under the consideration of policy outcomes and others' behavior, it is a "strategic vote". This thesis relates voters' strategic considerations to the government formation process: the chances for a party to gain seats, enter office, and affect overall policies. This implies that voters sometimes think like parties on the governmental consequences of the vote. Fr

The kinin-forming pathway is activated on endothelial cells and neutrophils when high-molecular weight kininogen (HK) is cleaved by plasma kallikrein liberating bradykinin, a potent mediator of inflammation. Kinins are released during inflammatory conditions such as vasculitis, associated with neutrophil influx around blood vessels. Some patients with vasculitis have elevated plasma levels of neut

BACKGROUND: Despite the fact that pancreatic cancer is the fourth leading cause of cancer-related death, there is little empirical evidence on its direct healthcare costs and, especially, its indirect costs due to loss of production. METHODS: The present study is a retrospective analysis of all patients with pancreatic cancer (excluding endocrine cancer) in the primary catchment area of Lund Unive
