A humus soil with a pH(H2O) of 4.9 was limed to a pH of 7.5 and was incubated together with samples from unlimed and field limed (pH 6.1) soils at 5, 20 and 30degreesC for up to 80 days. The changes in the phospholipid fatty acid (PLFA) pattern were most rapid for the bacterial community of the soil incubated at 30degreesC, while no changes were found in the soil incubated at 5degreesC. The respon
The book contains selected articles from research in different areas produced by scientists in Scandinavia. However, many of the articles are based upon professor Göran Fagerlund's original ideas. Titles:
1.Cementitious injection grouts - penetration ability (Alemo, J. & Hansson, P.).
2.A disadvantage of high performance concrete and a simple way to avoid it (Alexanderson, J).
This licentiate study has been completed as a part of a larger experimental program "Durability of Reinforced Concrete Structures in Marine Environment" carried out in Sweden and Denmark. The aim of this work has been to identify and critically evaluate some major parameters influencing the onset of active reinforcement corrosion in concrete in marine environment. Since the topic is naturally very
Artikeln diskuterar frågan om vittnets och vittnetsmålets trovärdighet utifrån ett antal nedslag i idéhistorien. Den berör vittnetsmålets epistemologiska, psykologiska och politiska problematik och utnyttjar som röd tråd linjen från Sokrates/Platon och Jesus/lärjungarna.

This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. By establishing air movement through an air-permeable layer below or above the concrete slab, the flowing air can absorb moisture from surroundi
A new method of reconstructing the susceptibility kernels of a linear, causal, time-invariant, homogeneous, and bi-isotropic medium from generic scattering data at normal incidence is presented. This inverse problem is shown to be well posed in the space of continuous functions furnished with the maximum norm, C[0,T]. A numerical example is given.
When compared with Chlorella vulgaris, Scenedesmus obliquus and Selenastrum capricornutum, C. sorokiniana presented the highest tolerance to acetonitrile and the highest O-2 production capacity. It also supported the fastest acetonitrile biodegradation when mixed with a suitable acetonitrile-degrading bacterial consortium. Consequently, this microalga was tested in symbiosis with the bacterial cul
The distribution and habitat ecology of Candelaria fruticans Poelt & Oberw. is discussed and a distribution map is provided, The distribution pattern is shared by a few species occurring on both sides of the Atlantic Ocean in mainly the subtropical and tropical zones.
The effective diffusion coefficient of ethanol in a 4 %(w/v) agarose gel at 25-degrees-C was measured using a diaphragm diffusion cell. The reproducibility was very good; a standard deviation of only 2% was obtained. The mean value (9.5 x 10(-6) cm2/s) agreed well with available theory and previous investigations.
Aunque los conocidos modelos de la escuela de Tartu contraponen la Cultura a la Naturaleza, realmente se refieren a la relación entre las culturas, una de las cuales se concibe como si fuera naturaleza. La inspiración para el concepto tardío de Lotman de la semiosfera, sin embargo, deriva de la oposición entre los hechos mentales (esto es, semióticos), que pertenecen al dominio de las ciencias soc
Value Based Management (VBM) has become a common tool for evaluating corporate strategies and projects from the perspective of shareholder value maximization, and can be an important input for corporate compensation systems. But traditional VBM frameworks make no systematic effort to distinguish between changes in performance attributable to macroeconomic fluctuations beyond management's control a
Streptococcus pyogenes is an important human pathogen that selectively interacts with proteins involved in the humoral defense system, such as immunoglobulins and complement factors. In this report we show that S.pyogenes has the ability to hydrolyze the chitobiose core of the asparagine-linked glycan on immuno globulin G (IgG) when bacteria are grown in the presence of human plasma. This activity

The disabilities of the arm, shoulder and hand (DASH) questionnaire is a self-administered region-specific outcome instrument developed to measure upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale. We performed cross-cultural adaptation of the DASH to Swedish, using a process that included double forward and backward translations, expert and la
