Protozoan Acanthamoeba polyphaga as a potential reservoir for Campylobacter jejuni
We showed by a laboratory experiment that four different Campylobacter jejuni strains are able to infect the protozoan Acanthamoeba polyphaga. C. jejuni cells survived for longer periods when cocultured with amoebae than when grown in culture alone. The infecting C. jejuni cells aggregated in amoebic vacuoles, in which they were seen to be actively moving. Furthermore, a resuscitation of bacterial
Experimental and numerical study of ground vortex interaction in an air-intake
The airflow field around air-intake related geometries has been investigated experimentally and numerically. The configuration of the experimental set-up is used to model a jet engine running near the ground. The experiments have been carried out using both PIV and LDA techniques in order to obtain the mean and fluctuating velocity field as well as the low speed frequencies related to the system o

Skenet som bedrog: Mai Zetterling och det svenska sextiotalet
Popular Abstract in Swedish Mai Zetterling (1925-1994) var under fyrtiotalet skådespelare, både på Dramatens scen och i populära svenska filmer. Under sextiotalet regisserade hon fyra långfilmer. Dessa filmer ? Älskande par (1964), Nattlek (1966), Flickorna (1968) och Dr. Glas (1969) ? bemöttes emellertid allt mer negativt av de svenska filmkritikerna. Under återstoden av sitt liv regisserade ZettMai Zetterling (1925-1994) was a popular actress in the 1940s. In the 1960s, she directed four feature films. The films ? Loving Couples (1964), Night Games (1966), The Girls (1968) and Dr. Glas (1969) ? were met with increasing hostility by Swedish critics, however, and after the 1960s, Mai Zetterling only directed two more feature films in her life, the British Scrubbers (1982) and the Swedish A

On the Dimension of Iterated Sumsets
Let A be a subset of the real line. We study the fractal dimensions of the k-fold iterated sumsets kA, defined as kA = {a(1) ... + a(k) : a(i) is an element of A}. We show that for any nondecreasing sequence {alpha(k)}(k=1)(infinity) taking values in [0,1], there exists a compact set A such that kA has Hausdorff dimension ak for all k >= 1. We also show how to control various kinds of dimensions s

Toward a More Efficient Implementation of Distributed-Delay Elements
This note studies lumped-delay approximations of distributed-delay elements arising in various problems involving delay compensation or preview utilization. Several approaches to reduce implementation complexity, understood as the number of delays required to attain a required accuracy level, are put forward. First, we derive the H2-optimal coefficients for a given delay pattern. This can be seen

Cytogenetic studies of benign breast lesions
Popular Abstract in Swedish Vår arvsmassa (DNA) finns packad i cellkärnan i de flesta kroppsceller i form av 46 kromosomer (23 par). Könscellerna innehåller ett halverat antal kromosomer. Det korrekta kromosomtalet hos människa beskrevs i Lund 1956, av Tjio och Levan. Kromosomerna innehåller tillsammans 50000-100000 gener, vilka är de delar av DNA-strängen som kan avläsas till proteiner. Cancer ärIn the present thesis benign breast lesions of various histologies, i.e., fibrocystic lesions from women with and without a known hereditary predisposition to breast cancer, fibroadenomas, phyllodes tumors, and papillomas were cytogenetically investigated with the aim to characterize the chromosomal patterns, and to relate the findings with those in breast carcinomas. No lesion-specific aberration
A short story about the Grevlunda motte in Scania, Sweden – former Denmark: from Bronze Age Grave to viking castle
One of Scanias earliest castles, Grevlunda, has been reinvestigated. The first excavation in 1913 gave an interesting result but the time was not ripe for understanding what really was found. In 2002 archaeologists in corporation with historians, and culture geographers found out that the Grevlunda was a motte of a rare construction. The pottery material gave a dating to the late 12:th century. Th
Assembling Ferromagnetic Single-electron Transistors with Atomic Force Microscopy
Ferromagnetic Single Electron Transistors (F-SETs) comprise ferromagnetic electrodes connected to a ferromagnetic- or non-magnetic central island via tunnel barriers. These devices are important for studies of spin-transport physics in confined structures. Here we describe the development of a novel type of AFM-assembled nano-scale F-SETs suitable for spin-transport investigations at temperatures
