The blade-tip region encounters high thermal loads because of the hot gas leakage flows. A common way to cool blade tips is to design serpentine passages with 180 degrees turn with the blade-tip walls inside the turbine blades. Improved internal convective cooling is therefore required to increase blade-tip lifetime. This chapter summarizes the heat transfer enhancement of an internal blade-tip wa
The database of photographic meteor orbits of the IAU Meteor Data Centerin Lund has gradually been updated. The version 2001, which has beenprepared for distribution and which will be released soon, containscomplete orbital and geophysical data on 4581 meteors (equinox J2000.0).A new meteor identification code consisting of the publication serialnumber, the author or station code and number of the
Vi är alla goda liberaler numera och tror på medborgerliga friheter och individens självbestämmande. Men hur ser liberalismen som distinkt politiskt alternativ egentligen ut? Att vara liberal är något mer specifikt än att gilla yttrandefrihet och tolerans. Liberalismen behandlas här som en politisk filosofi - en teori om det rättvisa samhället. Olika liberala riktningar diskuteras utifrån de grund
This paper examines the concept of ‘social value’, emphasised in the recently implemented Social Value Act. It argues that evaluations can play an important role in advocating the status of social value. Evaluations are tailored to highlight priorities and promote interests and can offer an important way of evidencing and promoting social value in order that it becomes an active ingredient in deci
Popular Abstract in Swedish Fågelflyttning omfattar några av de mest fascinerande beteendemässiga anpassningarna vi finner i naturen. Hos många fågelarter flyttar unga fåglar obereoende av erfarna vuxna individer och kräver således medfödd information om flyttningsvägar, rastning och övervintringsområden. Denna information har visat sig bestå av ett nedärvt program som innehåller flyttningsriktninIn many species of birds juveniles migrate independently of experienced adults and thus have to rely on innate information about migratory routes and wintering area. This information is encoded as a set of inherited migratory directions and a timing schedule that provides information on when and how far to migrate. Apart from these remarkable behavioral adaptations, migration also requires several
The need for biomass transportation depends on the balance between locally produced biomass and the local demand for fuel. In Sweden, more than 80% of the biomass assumed to be required to replace fossil fuels for the production of electricity and heat can be produced locally within each county, if biomass is extensively utilised. The average transportation distance of the remaining 20% will be be
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
