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

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

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

Several transportation factors concerning older and disabled people are under transition in Sweden at present. By the year 2010, the public transit system must be fully accessible for all passengers. The present survey studied older people, in order to assess the perceived travel opportunities. Questionnaires were sent to a sample of older citizens (75+) in three Swedish mid-sized municipalities.

Popular Abstract in Swedish Sedan årtionden tillbaks finns en stor mängd klorerade organiska miljögifter spridda i vår miljö (t ex DDT, PCBer och dioxiner). Djur får i sig miljögifterna främst med födan och eftersom dessa ämnen som regel är svårnedbrytbara och inte kan omsättas i kroppen i någon större omfattning leder detta till att de istället lagras upp i djuren, framför allt i fettvävnaden. EtChlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g., chlorine-containing discharge from industrial and house-hold waste and they may also occur naturally. ClFAs have a wide geographic distribution. They have,

Résumé : Le français écrit est caractérisé par de nombreuses marques morphologiques qui ne se prononcent pas. Cet article pose la question de savoir quand et sur quels constituants de la phrase les apprenants de français L2 font l’accord en nombre, souvent silencieux, à l’écrit. Dans une optique de développement qui s’inspire des travaux de Bartning et Schlyter (2004) dans le domaine du français p
