Long-term experimental studies on the interaction between silica fume and Portland cement in concrete subjected to air, water or sealed curing, are outlined. For this purpose 6000 kg of eight qualities of concrete were studied at 5 ages over a period of 155 months. Half of the concrete contained silica fume. Parallel studies of strength, hydration and rela-tive humidity were carried out. After 155

Abstract in UndeterminedIndividuals with the diagnosis of autism need well-functioning home environment to make progress and achieve an acceptable level of quality of life (QoL). Long-term mapping of the daily life of individual persons with disabilities with the purpose of understanding their living situation is rare. The present study deals with the QoL of an adolescent boy with autism and intel

A short presentation of a sermon from the tradition of Schartau at the 50 years' celebration of the Swedish-Norwegian union.

This thesis analyzes moral argumentation and meaning creation in the process of programmatic policy formulation in the Christian People's Party and Socialist People's Party in Denmark, and the Christian Democratic Party and Left Party in Sweden, focusing specifically on their policy deliberations about the European Community and the European Union from 1990-1996. The primary emphasis is not on pol

Objective: Rate of non-attendance following invitation for breast cancer screening is related to several socioeconomic conditions. To what extent this reflects differences with regard to individual and environmental circumstances, respectively, has received little attention. The purpose of this study was to investigate the effect of individual socioeconomic and area-level determinants on variation

Introduction Epidemiological observations suggest that sunlight exposure is an important determinant of hip fracture risk. The aim of this ecological study was to examine the relationship between latitude and hip fracture probability. Methods Hip fracture incidence and mortality were obtained from literature searches and 10-year hip fracture probability computed from fracture and death hazards. Re

Straw was evaluated as a biofilm carrier in the methanogenic stage of the two-stage anaerobic digestion of crop residues. Three reactor configurations were studied, a straw-packed-bed reactor, a glass packed-bed reactor and a reactor containing suspended plastic carriers. The reactor with the packed straw bed showed the best results. It had the highest methane production, 5.4 11(-1) d(-1), and the

We study experimentally the ionization of argon atoms by a train of attosecond pulses in the presence of a strong infrared laser field, using a velocity map imaging technique. The recorded momentum distribution strongly depends on the delay between the attosecond pulses and the laser field. We interpret the interference patterns observed for different delays using numerical and analytical calculat

A series of twelve full scale experiments with upholstered furniture and beds has been carried out. Ten experiments were performed inside an extensively equipped compartment with a door opening. In order to study the influence of the room on the fire development two experiments were carried out in the open outside the compartment. One experiment in the room was made with restricted ventilation sim

The radioanalytical procedures for the determination of neutron activation isotopes (Fe-55 and Ni-63) in environmental samples (water, sediment, sail and biological material) are described. The procedures are based on the coprecipitation of Fe-55 with iron hydroxide in natural and reactor water, ashing and mineralization of sediments, soil and biota samples, and the sequential separation and purif

OBJECTIVES: To determine the ability of transvaginal ultrasound, with or without saline infusion, to detect focally growing lesions in the uterine cavity in women with postmenopausal bleeding and endometrium > 5 mm, and to determine the accuracy of conventional ultrasound, saline contrast sonohysterography and diagnostic hysteroscopy under general anesthesia to diagnose endometrial polyps, submuco

A photoemision study of the surface states on Be(10 (1) over bar0) after Li adsorption at room temperature is reported. The surface band structure was mapped along four high symmetry directions of the SBZ. Fairly large shifts in the surface band locations were obtained but all surface states observed experimentally after Li adsorption were found to correspond to Be-derived states and no Li-derived

Cerebrospinal fluid (CSF), urine, platelet and neuroendocrine challenge tests of monoaminergic function give evidence of monoamines, especially serotonin, playing an important role in suicidal behavior. However, additional clinical, social and biochemical factors are necessary to better define suicide-prone psychiatric patients.

The ground and the excited state properties of the fullerene-linked quarter-thiophenes dyad were studied theoretically with the quantum chemistry method. To reveal the excited state properties of them in the vertical absorption process, the energies and densities of the HOMO and LUMO, the intramolecular charge transfer (ICT), locally excited (LE) are studied with transition density matrix, charge
