Popular Abstract in Swedish Blodet består av olika typer av celler med olika funktioner. De röda blodkropparna transporterar syre till alla delar av kroppen, blodplättar stoppar blödningar och en rad olika vita blodkroppar försvarar oss från olika typer av angrepp från till exempel virus eller bakterier. Generellt för alla dessa olika typer av celler är att de är kortlivade och måste ersättas kontMature blood cells are crucial for life, but they have a short lifetime and thus have to be replaced. These mature blood cells are produced by lineage restricted progenitors, which themselves are generated by rare multipotent hematopoietic stem cells (HSCs) in a highly dynamic process called hematopoiesis. In addition to the ability of HSCs to generate all blood cell lineages, they possess the uni

Popular Abstract in Swedish Zeoliter är en grupp av kisel-aluminium-föreningar, med karaktäristiska kanalsystem inuti strukturen, som har fått stor användning inom många områden inom teknik och vetenskap. Zeoliternas viktigaste användningsområden är som torkmedel, som molekylsiktar, som jonbytare och som katalysatorer. Användningen av naturligt förekommande zeoliter är relativt liten jämfört med aA highly dealuminated form of zeolite FAU, ultra-stable zeolite Y (USY), was used as an adsorbent matrix in the purification of proteins. Undesired proteins were removed from a crude preparation by adsorption on USY, increasing the purity of an unadsorbed protein (horse radish peroxidase), or the protein of interest was adsorbed on the zeolite and subsequently eluted through changes in the solutio

The development of organ transplantation technology is an extraordinary achievement that has saved the lives of many, but which also has created an endless need for body parts. In focus for this article is the trade in organs - especially organ trafficking in Moldova.

Energy efficiency scenarios are developed in the national and international context to explore and evaluate different policy designs and visions of how energy will be generated, distributed and used in the future. However, these scenarios are often developed using conventional bottom-up modelling tools that, to only a limited extent, take into account decentralised decision-making frameworks, such

The electrical output of low concentration systems with standard pv cells is heavily impaired by non uniform irradiation distribution on the cells. In order to design new concentrators that improve the system efficiency by homogenizing the light, a new method of evaluation has been developed. It is based on simulations, and generates an estimated annual output. The method consists of three steps,

This chapter presents the Development Policy Evaluation Model (DEVPEM), a new simulation model which captures four critical aspects of rural economies in developing countries: 1) the role of the household as both a producer and a consumer of food crops; 2) high transaction costs of participating in markets; 3) market linkages among heterogeneous rural producers and consumers; 4) the imperfect conv

The aim was to study and prospectively follow symptoms and sensitisation of laboratory animal workers with laboratory animal allergy (LAA) and workers at risk for development of LAA in terms of latency time, incidence, prevalence and possible health selection. Furthermore, the impact of animal positive skin prick tests (SPT) on lung function and individual risk factors for development of LAA was s

History plays an important role in the philosophy of human rights, more so than in philosophical discussions on related concepts, such as justice. History tends to be used in order to make it credible that there is a tradition of rights as a moral idea, or an ethical ideal, that transcends national boundaries. In the example that I investigate in this chapter, this moral idea is tightly spun aroun
