Formation of the binary pulsars J1141-6545 and B2303+46

The binaries PSR J1141-6545 and PSR B2303+46 each appear to contain a white dwarf that formed before the neutron star. We describe an evolutionary pathway to produce these two systems. In this scenario, the primary transfers its envelope on to the secondary, which is then the more massive of the two stars, and indeed sufficiently massive later to produce a neutron star via a supernova. The core of

Konflikt, kontroll, expertis. Att använda social forskning

Under de senaste åren har det skett en dramatisk ökning av tillämpad samhällsforskning i Sverige. Författarna frågar sig hur all denna forskning använts och vilken funktion den har, särskilt i socialt arbete. Är den ett bidrag till hunsade och förnedrade människors frigörelse, eller befäster den bara deras underordning genom att skapa en expertis som legitimerar den rådande ordningen?

Uppror och allianser. Politiskt våld i 1400-talets svenska bondesamhälle

Boken handlar om samtliga svenska bondeuppror (dvs uppror i det dåvarande kungariket Sverige) och krigiska bondeallianser på 1400-talet. Huvudtemat är den politiska och socialhistoriska läroprocess genom vilken de svenska bönderna insåg att politiskt våld lönar sig, att en militarisering av det politiska beteendet resulterar i ökat samhälleligt inflytande. Boken har en omfattande notförteckning s

Implementation of the signal component generator of a CALLUM 2 transmitter architecture in CMOS technology

This article presents an analog implementation of the signal component generator (SCG) of the CALLUM2 linear transmitter architecture. The proposed SCG is suited for integration in a standard 0.35 μm CMOS process, and has from simulations proven to be adequate when operating on an EDGE modulated baseband signal with a data rate of 270.833 ksymb/s. The total current consumption of the SCG is 2.0 mA

Comparison of field measurements and calculations of relative humidity and temperature in wood framed walls

Energy efficient wood frame buildings give besides a number of positive effects also risks for moisture damages. To avoid moisture damage in wood houses some parts of the Swedish construction industry use WUFI 1D calculation tool in the design phase. The purpose of this study is to demonstrate the coupling between measured and WUFI 1D calculated values of relative humidity and temperature. The fir

Prior Knowledge and Recognition Memory : a Computational Modeling Approach

Popular Abstract in Swedish Studiet av igenkänningsminne har varit centralt i minneslitteraturen under mer än ett århundrade, vilket har resulterat i ökad förståelse för hur olika minnesprocesser fungeraroch interagerar vid inkodning, lagring och framplockning av minnen. Igenkänningsminne är vanligtvis förklarat av mät-modeller och statistiska modeller vilka härstammar från tvåprocess teori och siFor more than a century, an immense interest has been devoted to the study of recognition memory, where a multitude of memory phenomena has been explained. Recognition memory is usually described with parsimonious measurement and statistical models, stemming from dual process theory and signal detection theory. In the present thesis, the most often used models of recognition memory are reviewed an

Conservation of energy and natural resources by recycling building waste

Recycling of building waste can considerably reduce the need for energy and natural resources and reduce the amount of material to landfill. Knowledge of the size of the annual conservation potential is important. The purpose of this study was to assess the conservation of energy and natural resources and the amount of material to landfill by recycling building waste in Sweden. Two recycling scena
