Effects of long-term exposure to trichloroethylene on the behavior of mongolian gerbils (Meriones Unguiculatus)

Two groups of Mongolian gerbils (Meriones unguiculatus) were continuously exposed to 150 ppm trichloroethylene (TCE) for 77 and 106 d, respectively. The behavior of the animals was tested in a symmetrical maze baited with sunflower seeds during a period of 23 d, beginning at the end of exposure. One additional group was exposed for 150 d and then allowed 40 d free from exposure before the start of

Pulse-stretcher upgrade

A new 250 MeV energy electron pulse-stretcher mode is designed where the MAX I ring is injected from a new linac system (Nucl. Instr. and Meth. A 490 (2002) 592). For the new slow extraction, we will try to achieve a lower emittance in the extraction plane by using a different extraction method. Injection and slow extraction are simulated.

Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer

This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and fin

Exercise-induced rib stress fractures: influence of reduced bone mineral density

Exercise-induced rib stress fractures have been reported frequently in elite rowers during the past decade. The etiology of rib stress fractures is unclear, but low bone mineral density (BMD) has been suggested to be a potential risk factor for stress fractures in weight-bearing bones. The present study investigated BMD in seven Danish national team rowers with previous rib stress fracture (RSF) a

Research Abstracts 2002

This report contains a short overview over the ongoing research and teaching activities of the PhD-students of the Department of Automatic Control, Lund University, in 2002.

2006. Nilsson Stutz, L. Setting it Straight. A re-analysis of the Mesolithic Barum burial according to the principles of Anthropologie ‘de terrain.’

The Mesolithic burial from Barum in Northeastern Scania has long been a subject of academic controversy regarding both the age of the burial and the sex assessment of the remains. A less public discussion has taken place regarding the initial position of the body in the burial. In this article, the documentation of the burial is analyzed in detail according to the taphonomic principles of anthropo

Approximate inverse preconditioners for some large dense random electrostatic interaction matrices

A sparse mesh-neighbour based approximate inverse preconditioner is proposed for a type of dense matrices whose entries come from the evaluation of a slowly decaying free space Green's function at randomly placed points in a unit cell. By approximating distant potential fields originating at closely spaced sources in a certain way, the preconditioner is given properties similar to, or better than,

Hand-Arm-Vibration Syndrome (HAVS): Is there a central nervous component? An fMRI study.

Hand-held vibrating tools may result in neuromuscular dysfunction and vasospastic problems of the hand. Sensory and motor dysfunction can be explained by injury to peripheral structures, but could also be due to changes in cortical somatotopic mapping of the hand in the brain. The purpose of the present study was to use functional magnetic resonance imaging (fMRI) to assess the somatotopic cortica

The impact of factor V mutation on the risk for occlusion in patients undergoing peripheral vascular reconstructions

OBJECTIVE: to determine the impact of Factor V-Leiden on the patency of peripheral vascular reconstructions. DESIGN: prospective, open and consecutive study. METHODS: a total of 775 patients, who were electively admitted between 1995 and 1997 to the vascular ward unit, were prospectively analysed for frequency of Factor V-Leiden mutation and patency of reconstruction (one month and one year). The
