This article focuses on experimental studies of self-heating characteristics of wood pellets. Controlled experiments have been conducted in physical scales from 1 dm3 to 4 m3 with wood pellets. Basket tests have been conducted according to the "crossing-point method" to derive kinetic data on the exothermic reactions responsible for self-heating and eventually spontaneous ignition. The kinetic dat
After decades of development of information systems dedicated to health professionals, there is an increasing demand for personalized and non-hospital based care. An especially critical domain is cardiology: almost two third of cardiac deaths occur out of hospital, and victims do not survive long enough to benefit from in-hospital treatments. We need to reduce the time before treatment. But sympto
Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the
Different phenomena such as complex flow field and heat release by combustion are involved in the heat transfer process in combustion chambers. This paper concerns prediction of heat load and wail temperature in a gas turbine combustor by taking different phenomena into account. Two dimensional axi-symmetric models were used to model the flow field and combustion in a premised combustor with two d
Popular Abstract in Swedish Elakartade (maligna) blodsjukdomar uppstår i den blodbildande benmärgen, vilken är innesluten i hålrummen i de skelettdelar som kan sägas täckas av en badmössa och en gammaldags baddräkt. En av de celltyper som bildas i benmärgen är plasmacellen, en vit blodkropp som utgör mindre än 2% av benmärgscellerna och som tillverkar specifika antikroppar vid infektioner. Vid monAcquired genetic changes have proved to be of diagnostic and prognostic importance in different hematologic malignancies as well as in some solid tumor types. However, although multiple myeloma (MM), an incurable disease, and its proceeding stage monoclonal gammopathy of undetermined significance (MGUS) are quite common, little is known about the karyotypic features of these plasma cell dyscrasias
The concept of graph cuts is by now a standard method for all sorts of low level vision problems. Its popularity is largely due to the fact that globally or near globally optimal solutions can be computed using efficient max flow algorithms. On the other hand it has been observed that this method may suffer from metrication errors. Recent work has begun studying continuous versions of graph cuts,
This paper evaluates how sharing a kindergarten classroom with low-achieving repeaters affects the long-term educational performance of regular first-time kindergarten students. Exploiting random assignment of teachers and students to classes in Project STAR, I document three sets of causal impacts: students who are exposed to repeaters (1) score lower on standardized tests at the end of kindergar
We are interested in elaborating how university teachers create and maintain their understanding of teaching and learning. To this respect the social context in which they act out their understanding seems to be important. In the literature there are examples of how stable teaching cultures appear, [1]- [3]. Some authors even label university teachers as conservative [4]. The issue here is not whe
