The lightning swept stroke along an aircraft in flight. Part II: numerical simulations of the complete process

During a lightning strike to an aircraft in flight, the lightning channel gets deformed in the airflow and displaced along the aircraft, a so-called swept stroke . The deformation and the displacement are caused by the interaction between the aerodynamic flow and the plasma properties of the channel together with the properties of the surface. We give a theoretical analysis and a numerical modelli

The use of assistive technology in different age-groups of old people

The aim of this study is to explore the use and perceived unfilled need for assistive technology (AT) for everyday life in three age-groups during the ageing process. Data on use and perceived unfilled need for AT from three age-groups were used; the very old age-group; 81-90, n=314, the oldest old age-group; 85-94, n=154 and younger agegroup, 67-71. The results show that the proportion of users h

Who is Marching for Pachamama? : An Intersectional Analysis of Environmental Struggles in Bolivia under the Government of Evo Morales

Popular Abstract in Swedish Movimiento al Socialismo (MAS) bildade regering i Bolivia 2006 med Evo Morales på presidentposten, framburna av folkliga protester mot tidigare, nyliberala regimer. Morales beskrivs ofta som landets första president med bakgrund i ursprungsbefolkningen. Hans regering utlovade en radikal omställning av den nationella politiken och tillkännagav att Bolivia nu är en "pluriEvo Morales and the Movimiento al Socialismo (MAS) took office in Bolivia in 2006, riding on the wave of fierce popular protests against previous, neoliberal regimes. Morales was depicted as the country’s first indigenous president. His government promised a radical transformation of national politics and rebranded Bolivia as a “plurinational state”. Under MAS, indigenous subjectivity has moved fr

mm-Wave Pulse-Generation Circuits in 65nm CMOS

Three mm-wave pulse generation circuits fabricated in a standard 65nm CMOS process are presented. Two versions are based on the cross-coupled NMOS LC-VCO (500um × 300 um), and one is based on the Colpitts VCO (600um × 300 um). No additional buffers are used in the cross-coupled versions, as they are directly loaded by 50 Ohms through a balun. They can produce measured pulses exceeding 8dBm peak ou
