Popular Abstract in Swedish Det finns många skäl till varför streptomyceter är en intressant grupp av bakterier att undersöka. Den här avhandlingen fokuserar på celldifferentieringen hos dessa organismer och deras förmåga att bilda en specialiserad typ av tåliga celler som kallas sporer. Genom att studera sporuleringsprocessen hos dessa bakterier kan man lära sig mycket om fundamentala livsprocessStreptomycetes are Gram-positive bacteria with a complex developmental life cycle. They form spores on specialized cells called aerial hyphae, and this sporulation involves alterations in growth, morphogenesis and cell cycle processes like cell division and chromosome segregation. Understanding the developmental mechanisms that streptomycetes have evolved for regulating for example cell division i

Intracerebral neural transplantation offers a new strategy to combat Parkinson’s and Huntington’s diseases. However, a host immune response against a histoincompatible neural graft in the brain may jeopardize transplant survival. We transplanted dissociated mesencephalic tissue prepared from Sprague-Dawley (SD) (syngeneic), Lewis (allogeneic) rats or mice (xenogeneic), into 6-hydroxydopamine (6-OH

Denna rapport behandlar gåendes korsande av gator i tättbebyggt område. Det empiriska underlaget för rapporten kommer från fältstudier som utfördes vid fyra platser i Malmö samt från STRADA data. Utöver detta kopplas de empiriska resultaten till vetenskaplig litteratur om gåendes trafiksäkerhet. Resultaten visar att fotgängares korsandeolyckor i tättbebyggt område med svåra eller dödliga skador ti

This article was given as a paper at the conference on Deification/Theosis at Drew University, Madison, N.J. in May 2004. The article adresses the growing interest in deification/theosis in contemporary Western theology. Recent research on deification/theosis in Luther and Thomas Aquinas are critically evaluated. The article ends with a proposal. For the better understanding of similarities and di

En undersökning av hur vanligt det är med utelämningar i fundamentet och icke satsformade meningar i ett mindre material med vykort 1995–2005 med utfallet att det är rätt påfallande vanligt (särskilt utelämnade subjekt i första person singularis), om än med stor individuell variation.

According to medieval canon law, a marriage could be declared invalid if the consent had been given through force or fear. This ruling was a natural consequence of the insistence on free consent as the only requirement for a valid marriage. It did, however, entail a number of both practical and theoretical problems. It could be difficult to prove force and fear within the family, but also to defin

Ultracold clouds of dimeric molecules can dissociate into quantum mechanically correlated constituent atoms that are either both bosons or both fermions. We theoretically model the dissociation of two-dimensional anisotropic molecular condensates for which this difference manifests as complementary geometric structures of the dissociated atoms. Atomic bosons are preferentially emitted along the lo

A neural network architecture for visual direction detection is proposed. The approach assumes a continuous flow of visual stimuli as input. The output of the network will as a consequence be a continuous flow as well. Each node in the network signals when motion is occurring at their position. Other nodes make use of this information in their computations. This allows, from a computationally view

The MAX-II synchrotron radiation source has since 1997 been operated routinely with a double RF system, 500 MHz active plus 1.5 GHz passive. Four Landau cavities have successfully provided increased Touschek beam lifetime, and damping of coupled bunch mode instabilities. However, the delivered power from the present 500 MHz RF system will be marginal for the operation of the planned MAX-II SC wigg

Popular Abstract in Swedish Slemhinnan i de övre luftvägarna utgör ett första skydd mot luftburna hot såsom bakterier, virus samt partiklar som kan förorsaka allergiska reaktioner. Kroppen reagerar på ett likartat sätt oavsett ursprunget till slemhinneskadan. Den reagerar med en aktivering av de inflammatoriska cellerna. Det finns ett välutvecklat samarbete mellan dessa celltyper. De har förmåga aIn this study we demonstrated the production of SLPI (Secretory Leukocyte Protease Inhibitor) in serous glands in the nasal mucosa. We have shown that the pattern of the expression of mRNA corresponds to the encoded protein. The encoded protein was detected by immunohistochemical methods and mRNA was discovered by in situ hybridisation. Nasal mucosa from 11 test subjects without atopic disposition

Liber Daticus Vetustior: A Martyrology from the Twelfth Century The purpose of the article is to explain what a martyrology is and how it was used, to situate Liber Daticus Vetustior (LDV) in the history of martyrologies and to elucidate its sources, character and original function. General accounts about Christian celebration, the cult of saints and the historical development of the martyrology

Kultursemiotiken per se analyserar mötet mellan kulturer. Begrepp som ego-kultur, extrakultur och icke-kultur är centrala i undersökningar som syftar till att blottlägga den självbild en kultur gör av sig själv i mötet med en annan. Dessa begrepp har paralleller på individnivå med de personliga pronomina i språket. I den uppsats jag ämnar presentera kommer jag därför att koncentrera mig på en disk
