Differences in phase transformation in laser peened and shot peened 304 austenitic steel

Laser Shock Peening (LSP) and Shot Peening (SP) are processes used to mechanically alter the surface properties of metals by inducing a transient high-pressure wave by a laser pulse or by a high-velocity impact of a peening particle. Both processes aim to induce compressive residual stresses near the surface and the level of residual stresses obtained from SP or LSP is similar.

Extraction and Modification of Macroalgal Polysaccharides for Current and Next-Generation Applications

Marine macroalgal (seaweed) polysaccharides are highly promising for next-generation applications in several industries. However, despite the reported comprehensive potential of these polysaccharides, commercial products are scarce on the market. Seaweed cultivations are increasing in number and production quantity, owing to an elevated global trend of utilization interest in seaweed. The extracti

Gene transfer across species boundaries in bryophytes : evidence from major life cycle stages in Homalothecium lutescens and H. sericeum

Background and Aims: The mosses Homalothecium lutescens and H. sericeum are genetically, morphologically and ecologically differentiated; mixed populations sometimes occur. In sympatric populations, intermediate character states among gametophytes and sporophytes have been observed, suggesting hybridization and introgression in such populations. Methods: We determined genotypes using bi-allelic co

Attitudes towards self-determination in health care : A general population survey in northern Sweden

Background: Today, patient self-determination has become an issue in many western countries due to the widespread availability and use of technology, which makes it possible to prolong life often in spite of severe disability and poor quality of life. Many people fear an overzealous use of modern life-saying procedures which merely serve to prolong the dying process. As a first step towards autono

Occupational exposures and risk of gastric cancer in a population-based case-control study

Gastric cancer trends seem to follow improvements in the environment of blue-collar workers, but the etiological role of occupational exposures in gastric carcinogenesis is scantily investigated. The risk of gastric adenocarcinoma in 10 common occupational industries, and particularly the long-term effects of asbestos, organic solvents, impregnating agents, insecticides, and herbicides, were evalu

Relational reference attribute grammars: Improving continuous model validation

Just like current software systems, conceptual models are characterised by increasing complexity and rate of change. Yet, these models only become useful if they can be continuously evaluated, validated and serialized. To achieve sufficiently low response times for large models, incremental analysis is required. Reference Attribute Grammars (RAGs) offer mechanisms to perform incremental analysis e

Functional Traits in Sphagnum

Peat mosses (Sphagnum) are ecosystem engineers that largely govern carbon sequestration in northern hemisphere peatlands. I investigated functional traits in Sphagnum species and addressed the questions: (I) Are growth, photosynthesis and decomposition and the trade-offs between these traits related to habitat or phylogeny?, (II) Which are the determinants of decomposition and are there trade-offs

On the persistence of the ether as absolute space

We analyse how the concept of the ether, playing the role of absolute space, is still present in physics. When the problem is considered in the context of classical mechanics, we show that vestiges of absolute space can be found in the standard presentation of inertial systems. We offer an alternative -- fully relational -- definition of inertial systems which not only eliminates the problem but i

Fire behaviour of selected polymeric materials : Numerical modelling and validation using microscale and bench scale test methods

The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. Failure in a fire test leads to increased expenses in the productdevelopment cycle leading to delayed realization of profits and low cost competitiveness in the

Identity construction and dialect acquisition among immigrants in rural areas–the case of Swedish-language Finland

The study focuses on how transnational migration affects the socio-political peripheries of communities. Specifically, we focus on identity construction and on how identities are worked out among second-generation immigrants from Bosnia, whose parents came to the Swedish-language countryside in Finland as refugees in the early 1990s. We analyse the Bosnians’ small stories and their use of linguist

The forkhead box containing transcription factor FoxB is a potential component of dorsal-ventral body axis formation in the spider Parasteatoda tepidariorum

In the spider, determination of the dorsal-ventral body (DV) axis depends on the interplay of the dorsal morphogen encoding gene decapentaplegic (Dpp) and its antagonist, short gastrulation (sog), a gene that is involved in the correct establishment of ventral tissues. Recent work demonstrated that the forkhead domain encoding gene FoxB is involved in dorsal-ventral axis formation in spider limbs.
