This paper describes a long term, high-resolution study of the activityof the Perseid meteor stream based on visual and radar observations atthe Onsala Space Observatory in Sweden. The data consists of 147 visualhourly rates and 1368 radar hourly rates. In a previous paper (Lindblad2000) a high-resolution study of the visual zenithal hourly rates ofbright Perseid meteors versus solar longitude was

The purpose of this thesis is to identify patents invented by researchers at Lund University, to describe the university inventors,and to understand the main factors that influence their patenting activities. The analysis focuses on inventors in relation to their environment. A number of factors influence scientists’ decisions to patent. Internal factors related to individuals such as solving the

This thesis is based upon four original papers describing the characterisation of mantle cell lymphoma (MCL) tumours and cell lines in comparison with different populations of normal B cells. Gene expression profiling, which were used in the studies, has during recent years developed as an important tool in characterisation of different types of malignancies. In this thesis, the technique is used

It is commonly assumed that speech production is initiated and guided by clear pre-verbal intentions. These intentions are moreover supposed to function as a standard of accuracy against which actual performance can be measured. Alternative positions to such a centrally governed process have been offered, but very few empirical attempts have been made to explore the issue. We aimed to remedy this

Antibody-based microarray is a novel technology with great potential within high-throughput proteomics. The process of designing high-performing antibody (protein) microarrays has, however, turned out to be a challenging process. In this study, we have developed further our human recombinant single-chain variable-fragment (scFv) antibody microarray methodology by addressing two crucial technologic

Oxytocin (OT) and vasopressin (VP) are neurohypophyseal hormones with potent stimulatory actions on the uterus. In order to determine whether these hormones may have a paracrine action on the uterus, OT and VP gene expression was studied in myometrium from pregnant rats at gestational ages of 14 and 20 days, and from ovariectomized animals treated with oestradiol and progesterone. OT and VP mRNA c

beta 2-microglobulin (beta 2m) was found to interact with many group A streptococcal strains. The interaction appeared to require multipoint attachment, since monomeric beta 2m in solution showed no binding, whereas both beta 2m monomers bound to liposomes, and beta 2m in aggregates showed affinity for the bacteria. Aggregated HLA antigens (-A, -B and -C) and aggregated beta 2m exhibited the same

This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. By establishing air movement through an air-permeable layer below or above the concrete slab, the flowing air can absorb moisture from surroundi

Popular Abstract in Swedish Jordens havsnivå förändras kontinuerligt. I ett längre geologiskt tidsperspektiv styrs förändringarna av processer i jordens inre, men i ett kortare tidsperspektiv spelar yttre processer, såsom tillväxt och avsmältning av inlandsisar, stor roll för havets nivåförändringar. Det grönländska istäcket är idag norra halvklotets enda inlandsis och dess tillväxt och avsmältninNew results are presented from the investigation of relative sea-level changes in the Nanortalik and Qaqortoq-Narsarsuaq areas in SW Greenland from c. 11 000 cal. years BP to the present. Isolation and transgression sequences from seven lakes and seven tidal basins are identified using some of the traditional methods such as stratigraphic description, magnetic susceptibility, saturated induced rem

Helicobacter pylori is a world-wide spread bacterium that causes persistent infections and chronic inflammations that can develop into gastritis and peptic ulcer disease. It expresses several adhesin proteins on its surface that bind to specific receptors in the gastric epithelium. The most well-known adhesin is BabA, which has previously been shown to bind specifically to the fucosylated blood gr

The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (W '), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 1.04 fb(-1). No excess above Standard Model expectations is observed. A W ' with S

Cytomegalovirus (CMV) is a virus that causes chronic infections in a large set of the population. It may cause severe disease in immunocompromised individuals, is linked to immunosenescence and implied to play an important role in the pathogenesis of cardiovascular diseases and cancer. Modulation of the immune system's abilities to manage the virus represent a highly viable therapeutic option and
