This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. At high load the exhaust heat was increased more than at high engine speed. Swir
En utveckling av den s. k. väte-ekonomin, där vätgas (H2) används som energibärare, skulle – rent teoretiskt – kunna lösa människans energiproblem då vatten skulle kunna användas som bränsle. För att nå detta mål krävs dock väsentlig teknologisk och vetenskaplig utveckling. Ur ett rent vetenskapligt perspektiv, måste bl a (energisnåla) kemiska metoder att skapa stora mängder vätgas utvecklas. MångAbstract – The mixed-valence triiron complexes [Fe3(CO)7-x(PPh3)x(µ-edt)2] (x = 0, 1, 2; edt = SCH2CH2S) and [Fe3(CO)5(κ2-diphosphine)(µ-edt)2] (diphosphine = dppv, dppe, dppb, dppn) have been prepared and structurally characterized. In comparison to the diiron complex [Fe2(CO)6(µ-edt)], [Fe3(CO)7(µ-edt)2] catalyzes proton reduction at 0.36 V less negative potentials, which is a significant energe
In a future fossil-free circular economy, the petroleum-based plastics industry must be converted to non-fossil feedstock. A known alternative is bio-based plastics, but a relatively unexplored option is deriving the key plastic building blocks, hydrogen and carbon, from electricity through electrolytic processes combined with carbon capture and utilization technology. In this paper the future dem

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
Clinical education is a significant part of nursing education on all levels of education. A lot of effort is made by educational providers to prepare the students for their clinical placement (Levett-Jones et al., 2015). At best, this is a shared enterprise, involving representatives from the profession in creating a useful clinical placement for the students. However, the strain on clinical nurse
This article analyses some young men’s specific ways of retelling victims’ experience when the perpetrators have an immigrant background. In qualitative interviews with twenty young men, fear of being seen as intolerant was distinguished by their expressive caution. This involved using various aligning actions: presenting disclaimers and accounts, but also in terms of hesitant speak, re-takes and This article analyses some young men’s specific ways of retelling victims’ experience when the perpetrators have an immigrant background.
