Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. During the transport the pilus proteins are attached to a chaperone that protects them from aggregation and proteloty

A collection of studies on different theories and metaphors on the nature of man in his ambivalence (with Pascals words "neither angel nor beast"), its constants and variables, from antiquity to the Middle Ages and pre-modern times. The focus is on the concept "person". Third, revised edition.

A composition is a vector of positive components summing to a constant. We consider the problem of describing the correlation between two compo- sitions. Using a bicompositional Dirichlet distribution, we calculate a joint correlation coefficient, based on the concept of information gain, between two compositions. Numerical values of the joint correlation coefficient are calcu- lated for compositi

Popular Abstract in Swedish Enchytraeider och naidider, och deras reaktioner på miljöbetingad stress. Syftet med denna avhandling var att studera naidider och enchytraeider. Tonvikten är lagd på deras fortplantningsbeteende och hur de påverkas av miljöbetingad stress. Maskarna utsattes för stress i form av varierande kvalitet på födan, torka, och giftiga ämnen. Enchytraeider och naidider är bådaMy thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. In laboratory experiments enchytraeids reacted to chemical stress with

An article about and interview with Latvian-American artist Boris Lurie (1924-2008), co-founder of the NO!art movement in the beginning of the 1960s.

The epitome of this article is the reflection upon the question of “How long is now?” This question is interpreted within the context of the Iraq war, 2003 and onwards, as the enduring now specified. Drawing on parallels from the European World War II experience and the use of “Auschwitz” as a metaphor for a specifically Christian guilt articulated in relation to the Pauline eschatological hope of

Popular Abstract in Swedish Så gott som alla metaller reagerar vid normala omständigheter med syret i luften och oxideras, vilket förändrar materialets egenskaper. T.ex. rostar järn efter hand, något som alla bilägare är bittert medvetna om. Oxider behöver dock inte vara negativa, utan kan även fungera som barriärer mot fortsatt korrosion, isolerande skikt i mikroelektronikkomponenter m.m. FöljaktThe oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scannin

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Skivepitelcancer i huvud- och halsregionen (SCCHN) Kliniska aspekter Prognosen vid SCCHN är i stort sett oförändrat dålig sedan 30 år tillbaka; cirka hälften av patienterna dör av sin sjukdom. Trots stora tekniska framsteg kring behandlingsteknikerna (ofta en kombination av kirurgi, strål- och i viss mån cellgiftsbehandling) medför dAt present, clinical outcome or response to therapy can not be fully predicted in individual cases of squamous cell carcinoma of the head and neck (SCCHN). The overall aim of the present studies was to investigate potential prognostic factors, more closely related to the malignant progression of a tumor than the established markers, such as the TNM-classification system. Tumor samples were investi

Purpose – In the recent redefinition of the European Commission's corporate social responsibility (CSR) strategy, attention is brought to CSR as a motor for innovation. However, literature in the area remains scarce. This chapter describes and discusses innovation as a consequence of a firm's CSR activities. Methodology/approach – The empirical part of the chapter is based on the content analysis

I detta kapitel analyseras kvalitetsidéns resa inom hälso- och sjukvården från det att idén började göra sig gällande i mitten av 1980-talet och fram till att den lagstadgades i slutet på 1990-talet. De problem som kvalitetsidén sätts som lösning på inom den svenska hälso- och sjukvården beskrivs och utvecklingen av kvalitetssäkring följs från idé till lag. I kapitlet beskrivs några av de försök s
