Hematopoietic stem cells (HSCs) compose a rare population of undifferentiated cells, residing in the bone marrow of adult individuals, ensuring life-long maintenance and replenishment of the blood system. This fantastic achievement is possible owing to two special characteristics of the HSCs: their ability to make copies of themselves (self-renew), and their capacity to differentiate to all lineag

Kolhydratsystem så som alkylglycosider, cellulosa och cyklodextrin är miljövänliga förnybara material som används inom många områden i dagens samhälle; som bärare av aktiva substanser i läkemedelstabletter, matsmältningsfiber, papper, kosmetika och hygienartiklar för att nämna några. De är fasta substanser uppbyggda av molekyler ordnade i en viss struktur. Med tiden, och eventuell yttre påverkan, In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. Adsorption of minuscule amounts of water from the atmosphere may have huge effect

The servo problem for a wide class of nonlinear system is considered.A quantitative bound on system trajectories is derived. For piecewise linearsystems the bound is shown to be computable in terms of linear matrixinequalities.

Liksom i vår köttsliga värld kräver nätets identitetsskapande processer att vi vågar vara öppna och utforskande, i ett försök att forma det som blir våra jag. Visst, det går fel ibland. Men ansvaret får aldrig läggas på den som drabbats, utan måste läggas rätt. Ibland är det på förövaren, men än oftare på destruktiva strukturer som vi ständigt lever bland.

This paper study the concepts of social movements and non-traditional security, followed with the analysis of state regimes reaction in dealing such non-traditional challenges, utilizing the case study of Thailand, Malaysia and Burma. This paper end with a conclusion and hope to yield for a potential significant both empirically and theoretically to the understanding and bridging the studies of so

Climate change impacts increase pressure on challenges to sustainability and the developmental needs of cities. Conventional, “hard” adaptation measures are often associated with high costs, inflexibility and conflicting interests related to the dense urban fabric, and ecosystem-based adaptation (EbA) has emerged as a potentially cost-efficient, comprehensive, and multifunctional approach. This pa

Structural change consists of the long-term changes in the sectoral composition of output and employment. We introduce a structural change perspective to the study of income inequality in 27 countries of the developing world for the period 1960–2010. The service sector has become the main employer, but the agricultural sector is central to the income distribution because poverty is mostly rural, a
