Transport and sorption phenomena in concrete and other porous media

The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. One paper and one report deals with moisture transport in concrete and the remaining papers and reports deal with absorption and physical properties related to adsorption for different materia

Effects of polyamines on intracellular calcium and mechanical activity in smooth muscle of guinea-pig taenia coli

The effects of the polyamines putrescine, spermidine and spermine on the mechanical activity in smooth muscle from guinea-pig taenia coli were investigated. Tissue concentrations of spermidine and spermine were about 240 and 160 nmol g-1, respectively, while the putrescine concentration was much lower (4 nmol g-1). Intracellular [Ca2+] was determined using the Fura-2 method and the effects of extr

Fruit and vegetable consumption in relation to risk factors for cancer: a report from the Malmo Diet and Cancer Study

OBJECTIVE: To examine the associations between the consumption of fruit and vegetables and other markers of cancer risk. DESIGN: A cross-sectional survey within the population-based prospective Malmo Diet and Cancer (MDC) Study. Information on food habits was collected through the modified diet history method designed and validated for the MDC Study. Data on smoking and alcohol habits, leisure tim

Optimizing flow cytometric DNA ploidy and S-phase fraction as independent prognostic markers for node-negative breast cancer specimens

Developing a reliable and quantitative assessment of the potential virulence of a malignancy has been a long-standing goal in clinical cytometry. DNA histogram analysis provides valuable information on the cycling activity of a tumor population through S-phase estimates; it also identifies nondiploid populations, a possible indicator of genetic instability and subsequent predisposition to metastas

Alternative NAD(P)H dehydrogenases of plant mitochondria

Plant mitochondria have a highly branched electron transport chain that provides great flexibility for oxidation of cytosolic and matrix NAD(P)H. In addition to the universal electron transport chain found in many organisms, plants have alternative NAD(P)H dehydrogenases in the first part of the chain and a second oxidase, the alternative oxidase, in the latter part. The alternative activities are

Skapande av femininitet : Om kvinnor i missbrukarbehandling

Popular Abstract in SwedishDenna avhandling handlar om kvinnor i missbrukarbehandling och deras beskrivningar av sig själva som kvinnor, den s.k. femininitetsprocessen. Syftet är att beskriva och försöka förstå behandlingens betydelse i kvinnornas femininitetsprocesser och vilken innebörd rusmedel, män, den egna kroppen, moderskap och sexualitet har och har haft däri. Avhandlingen har huvudsakligeThis thesis is about women in drug abuse treatment and their descriptions of themselves as women - their process of becoming feminine. The aim of the thesis is describing and trying to understand the meaning of the treatment in the women's femininity processes and what significance drugs, alcohol, men, the own body, motherhood, and sexuality have and have had in the process. The emphasis is on the

The influence of the number of thermal layers on the clothing insulation of a cold-protective ensemble

The required thermal insulation in cold conditions and time limits for cold exposure can be predicted by the thermal index IREQ/DLE (Insulation REQuired), described in ISO/TR-11079. The thermal insulation of a clothing ensemble can be measured with a thermal manikin or estimated according to ISO 9920. The basic thermal insulation of single garments (Iclu) can be summated to estimate the basic insu

Methotrexate ameliorates T cell dependent autoimmune arthritis and encephalomyelitis but not antibody induced or fibroblast induced arthritis

Objective: To investigate the mode of action of methotrexate (MTX) in different types of models for rheumatoid arthritis (RA) and multiple sclerosis (MS). Methods: Models for RA and MS were selected known to have different pathogenesis - that is, fibroblast induced arthritis in SCID mice, collagen induced arthritis (CIA), anticollagen II antibody induced arthritis (CAIA), and experimental autoimmu

Icodextrin improves the fluid status of peritoneal dialysis patients: Results of a double-blind randomized controlled trial

Worsening fluid balance results in reduced technique and patient survival in peritoneal dialysis. Under these conditions, the glucose polymer icodextrin is known to enhance ultrafiltration in the long dwell. A multicenter, randomized, double-blind, controlled trial was undertaken to compare icodextrin versus 2.27% glucose to establish whether icodextrin improves fluid status. Fifty patients with u

Case-based reasoning, a promising tool to face solids separation problems in the activated sludge process

Classical control has serious limitations when faced with solids separation problems in the activated sludge process. Lack of knowledge about the mechanisms involved in the imbalance within the different microbiological communities implies that a general solution to these undesirable situations has not yet been provided. However, operators have to make decisions based on their experience and intui

Combined oral and enema treatment with Pentasa (mesalazine) is superior to oral therapy alone in patients with extensive mild/moderate active ulcerative colitis: a randomised, double blind, placebo controlled study

Background and aims: Oral aminosalicylates are well established in the treatment of active mild/moderate ulcerative colitis (UC) when the disease is extensive (that is, beyond the splenic flexure). The majority of clinical symptoms relate to disease activity in the distal part of the colon and therefore this study was designed to investigate if adding a mesalazine enema to oral mesalazine has addi

Soft Security and the Presidency: Swedish Policy towards the Northern Dimension

The Council Presidency offered Sweden a possibility to contribute not only to a number of important issue areas but also to what we may call the ‘foreign policy’ side of the EU.A general question was, of course, what sort of impact Sweden could make in this field, given its background as a nonaligned and small state — a country generally regarded as hesitant in terms of supranational policy-making
