Linearity of bulk-controlled inverter ring VCO in weak and strong inversion

Frequency modulation in ring VCOs is investigated. Primarily, the linearity of conversion from input voltage to output frequency is considered. Bulk-voltage control of the threshold voltage of the VCO transistors is found to be a very promising approach for applications in frequency /spl Delta//spl Sigma/ converters. Different approaches apply in presence of high supply voltages, when transistors

Immunsvar och inflammation vid Crohns sjukdom. Snart mojligt driva diagnostiken langre och utveckla mer specifika lakemedel

The chronic inflammation in Crohn's disease may be caused by aggressive response to bacterial antigens normal to the gut. Genetic and environmental factors modify the inflammatory response evoked by damage to the mucosal gut barrier. Genetic factors may also determine the subsequent course of chronic inflammation. Further elucidation of the pathogenesis might improve our understanding of the heter

Does Partnership Exogamy Increase the Risk of Separation? The Impact of Cultural Dissimilarity on Partnership Dissolutions in Sweden 1990-2005

In this paper the connection between exogamy and partnership dissolution is analyzed using individual level register data for natives and immigrants moving to Sweden after 1968. We study both formally married and cohabiting unions, from the birth of the first child until dissolution of the partnership. Using event history models we study the impact of type of union (endogamous, exogamous with a na

Discourse for Normalising What? The Learning Organization and the Workplace Trade Union Response

Recent critics of organizational learning and its normative offshoot the ‘learning organization’ have posited that conceptualisations of organizations based on knowledge and learning constitute a rhetorical device enabling elites to assert different forms of control through a new ‘normalising discourse’. The paper, whilst welcoming such critique, nevertheless asks whether it is adequate to dismiss
