Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. Metal affini
The paper provides an exploratory empirical survey of Application Service Providers (ASPs) and their clients. The research question is: what do Small and Medium-sized Enterprises (SMEs) base their decision on when adopting the ASP concept? The concept, ASP, consists of software vendors, and an ASP enterprise, which act as a third part firm in a business model. For its clients it forms a strategy t
This essay offers a critique of technological determinism in regards to expectations on how technology may influence visual culture.
Popular Abstract in Swedish Värmebehandling av livmoderslemhinnan med ballongkateter - en ny metod att behandla rikliga mensblödningar. Mera än 11% av svenska kvinnor besväras av rikliga menstruationer (menorrhagi). När läkemedelsbehandling mot menorrhagi inte hjälper kan livmodern opereras bort. Varje år, i Sverige, opereras livmodern bort hos 4-5000 kvinnor på grund av rikliga mensblödningar. DThermal endometrial destruction by means of a silicone balloon catheter is a new form of treatment for menorrhagia aimed at reducing menstrual blood loss. The purpose of the present work was to study, experimentally, the thermal effects on and the thermal conductivity of uterine tissue, to obtain a basis for the estimation of optimal treatment conditions by means of numerical analyses using a comp
In the last decades, the growing competitiveness of the market has continuously driven the forming companies to highly optimize their products regarding offered performance at minimum cost. In order to achieve better products, studies where conducted with different material models when simulating the forming process of titanium. The material is often used in heat exchanger applications. Titanium h
2014 års Demokratiutredning har i uppgift att analysera behovet av och utarbeta förslag till åtgärder för att öka och bredda engagemanget inom den representativa demokratin. Utredningen ska även föreslå åtgärder i syfte att stärka individens möjligheter till delaktighet i och inflytande över det politiska beslutsfattandet mellan de allmänna valen. En särskild uppgift för utredningen är att belysa
Popular Abstract in Swedish Även om vi befinner oss i en tidsepok av informationsteknologi och superdatorer så utförs dagens forskning baserat på Galileos vetenskapliga principer. Trots det så finns det idag inget behov av att klättra upp i det lutande tornet i Pisa för att observera hur ekvationerna för rörelse, enligt den klassiska mekaniken, tar sig uttryck för fallande kroppar. Samma experimenRecent years have witnessed a growing interest of the scientific community for the use of ab initio and density functional theory methods in theoretical studies of molecules containing many atoms. However, the `scaling wall' of some of the most accurate of such methods is often an obstacle for their applicability to systems of real-life interest, e.g. in biochemistry and nanotechnologies, one bott
Avsikten med detta projekt har varit att utveckla väl fungerande rutiner för PIXE-analys av biologiska prov med anknytning till exponering i arbetsmiljösituationer. Kravet på metoderna är att de tillvaratar PIXE-metodens fördelar (multielementanalys, små prov, snabb analys, låga detektionsgränser) och samtidigt förändrar eller förstör så lite som möjligt av den information som finns i de ursprungl
The concept of a holistic innovation policy is defined in this article, with discussions of what it is, why it is relevant, and how it can be implemented to enhance product innovation. It is shown that the innovation systems approach has diffused rapidly during the latest decades and has completely replaced the linear view in the field of innovation research. The majority of European countries are
Why is waste such an important topic for understanding the management of overflow? First, because waste is a classic symbol of overflow: to be flooded with too much stuff that demands handling, sorting, and decision-making is a feeling well known in consumer society. Facts and figures speak of the same overflow. Waste disposal is a growing problem. The downside of consumption is a growing mountain
Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available. This thesis focuses on dehydration methods that take into account the fragile and complex cellular tiss
With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. In this thesis, different automated classification approaches, focusing on
