Background: Traditionally average values of the whole population are considered when analysing microbial cell cultivations. However, a typical microbial population in a bioreactor is heterogeneous in most phenotypes measurable at a single-cell level. There are indications that such heterogeneity may be unfavourable on the one hand (reduces yields and productivities), but also beneficial on the oth

The collective identity is subject to permanent negotiation. Due to the lack of incentive to offer public statements, the collective identity of Japanese bureaucrats (or kanryo, 官僚) has been constructed separately inside and outside of the ministries. This paper explores how the collective identity of kanryo has been constructed in two Japanese national newspapers as outsider discourses using stru

Popular Abstract in Swedish Folat är ett B-vitamin som kan bidra till minskad risk för en rad sjukdomar, däribland en speciell form av blodbrist, ryggmärgsbråck hos nyfödda, hjärt- kärlsjukdom och vissa cancerformer. Folat förekommer framför allt i många vegetabiliska livsmedel. Speciellt höga halter har gröna bladgrönsaker, baljväxter (t.ex. kikärtor) och lever. Betydande folatkällor i svensk koFolate is a B-vitamin that may influence cancer development via its role as methyl donor for DNA synthesis and methylation. Plant foods contain many bioactive compounds including folate and fiber. Results from the Malmö Diet and Cancer (MDC) cohort indicate lower breast cancer risk at high fiber intake. Folate intake may partly explain this association. Aims of this thesis were to examine if i

Superantigens (SAgs) are bacterial toxins that interact with immunoreceptors, T cell receptor (TCR) and major histocompatibility complex (MHC) class II, conventionally through the variable beta-domain of TCR (TCRV beta). They induce a massive release of cytokines, which can lead to diseases such as food poisoning and toxic shock syndrome. In this study, we report the X-ray structure of the ternary

In breast cancer, high levels of the inflammatory cytokine interleukin-6 (IL-6) have been associated with disease-free survival and treatment resistance. Increased serum levels of IL-6 have been correlated with increased levels of NF-κβ and aromatase expression in adipose tissue. Several IL6 single nucleotide polymorphisms have been associated with breast cancer prognosis, but the impact may diffe

Semiconductor nanowires have made a deep impact on materials science related research, and are being explored for applications in several disciplines. Many of these applications require heterostructures, which can be defined as the combination of two or more materials within the same nanowire structure. In this paper we briefly review the current state-of-the-art concerning epitaxial nanowire hete

Multiple Sclerosis (MS) is a progressive autoimmune inflammatory and demyelinating disease of the central nervous system (CNS). T cells play a key role in the progression of neuroinflammation in MS and also in the experimental autoimmune encephalomyelitis (EAE) animal models for the disease. A technology for quantitative and 3 dimensional (3D) spatial assessment of inflammation in this and other C

Research on media and democracy mobilizes a range of conceptual versions of the subject. This is often done implicitly, or out of habit, with a specific model becoming established in any given research tradition. This presentation argues that different theories of the subject can have different implications for our understanding of citizenship and democracy. The text surveys a number of versions,

Abstract in UndeterminedAbstractThe aim of this study is to investigate the structural licensing and the semantics of the dative-DP in ditransitive constructions in German from a cognitive and construction grammar perspective.While the indirect object in constructions with prototypical ditransitive verbs is said to be a lexically selected argument of the verb, the indirect object in beneficiary di

Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. First, we study the influence of the atomic genera

Increasing nitrogen(N) deposition due to anthropogenic activities has become a significant global change threat to N-poor terrestrial ecosystems. We compared bacterial growth and nutrients limiting bacterial growth in one of the longest running experiments on increasing N-deposition to a temperate forest, the Chronic Nitrogen Amendment Study at Harvard Forest, USA. Soil samples were collected in f

Popular Abstract in Swedish Intubationer (nedsättande av andningsslang i luftstrupen) i samband med generella anestesier kan påverka lungfunktionen med en sänkt arteriell syresättning (SpO2) som följd. Medel för inhalationsanestesi administreras och elimineras via andningsvägarna. Anestesimedlen tas upp i blodet från lungans alveoler genom diffusion och transporteras löst i blodplasma till hjärnanBackground and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP. Methods: Prospective, randomised, clinical studies. ASA І and II abdominal surgery patie

We report a systematic study of the relationship between crystal quality and electrical properties of InAs nanowires grown by MOVPE and MBE, with crystal structure varying from wurtzite to zinc blende. We find that mixtures of these phases can exhibit up to 2 orders of magnitude higher resistivity than single-phase nanowires, with a temperature-activated transport mechanism. However, it is also fo

Alginate microbeads, produced by emulsion/internal gelation, were studied for the entrapment and microcultivation of microbial cells with biotechnological potential. An anaerobic consortium which was selected for its capacity to degrade complex carbohydrates, and a pure culture of cellulose degrading bacteria were used for entrapment studies. Optimization of conditions for the formation of spheric

In this study a new type of honeycomb-patterned micro-porous polyester fibre was used to develop good moisture absorption and quick drying properties of woven fabrics. Details of the development and after-finish processes of the fabrics were illustrated. The water transport, vapour transmission and quick dry properties of the seven different end products were also investigated. It was evident that

In our previous work, the agreement between the theoretical and measured wavelength for the 4f-M1 transition of Ag-like W shed light on the importance of a careful treatment of all core-valence correlation effects to obtain a reliable value of this fine structure energy separation. To confirm these results and extend the analysis isoelectronically, we have undertaken an experimental and theoretica

The Lund SSAMS machine has been in routine operation since 2004. We present results from the last year of operation of the facility. The reference sample IAEA C7 and the "old" oxalic acid, Oxl, were used as secondary standards. As primary standard for calculations the OxII was used. The background and long term stability of the facility are discussed. We also report on the quality of the C-13/C-12
