Islanding detection and connection requirements

This paper reflects how anti-islanding protection has developed with increasing DG penetration. Starting from a local issue it has developed to possibly affect system security. The focus here is on how islanding detection methods and anti-islanding protection settings relate to distribution level and TSO requirements. It is confirmed using field measurements and simulations that the most common pa

Synthesis and Characterization of Diphenyl-2-thienylphosphine Derivatives

The reaction of [Co2{μ-C2(CO2Me)2}(CO)6] with the ligand diphenyl-2-thienylphosphine, PPh2(C4H3S), yields the complexes [Co2{μ-C2(CO2Me)2}(CO)5{PPh2(C4H3S)}] (1) and [Co2{μ-C2(CO2Me)2}(CO)4{PPh2(C4H3S)}2] (2). The related complex [Co3(μ3CMe)(CO)9] reacts with the same ligand to give [Co3(μ3-CMe)(CO)8{PPh2(C4H3S)}] (3) and [Co3(μ3-CMe)(CO)7{PPh2(C4H3S))2] (4). Thermolysis of 1 at 80°C leads to part

Streptococcal M protein and human C4BP

Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. The surface associated M protein of Streptococcus pyogenes, a common human pathogen, exhibits antigenic variation due to an N-te

Because we can - eHealth encounters New Public Management in Swedish Healthcare

Since November 2012 all citizens in Uppsala County in Sweden have access to their medical record on the internet sight “my health contacts”. This is the first step in a EU deployment- project where a total of 12 different eHealth services will be launched over time. The IT director of the county has engaged himself in the idea of medical records and other eHealth services since 1997 and has had se

Does reduced heat production during mild whole body cooling override increased heat generation by pre-shivering muscle tension?

INTRODUCTION Preshivering thermogenesis (developing muscle tension) may not be noticed in static situations due to reduced metabolism under mild body cooling. This paper describes the observations of metabolic and heart rate changes under mild body cooling. METHODS Eight men participated in the study. The subjects were dressed in shorts, socks and shoes, and were seated. The air temperature (32 °C

Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

Popular Abstract in Swedish Tensider är en mycket vanlig typ av kemikalier som använts i tusen år och som man ofta stöter på i vardagliga livet. De ingår i exempelvis rengöringsmedel, diskmedel, tvättmedel, lim, målarfärger, hudkrämer och schampo. Tensider är ytaktiva ämnen som anrikas på ytor där de reducerar ytspänningen och därmed ändrar ytans egenskaper. En tensidmolekyl består av en hydrofil A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

Representing Guard Dependencies in Dataflow Execution Traces

Heterogeneous parallel systems are becoming mainstream computing platforms nowadays. One of the main challenges the development community is currently facing is how to fully exploit the available computational power when porting existing programs or developing new ones with available techniques. In this direction, several design space exploration methods have been presented and extensively adopted

Language Subject Ideology: The Politics of Representation in Virginia Woolf's To the Lighthouse, Djuna Barnes's Nightwood and Gertrude Stein's Lucy Church Amiably

This dissertation investigates the relation between aesthetics and politics by interpreting three experimental novels by Virginia Woolf, Djuna Barnes and Gertrude Stein. By theorizing the relation between language, subject, voice and ideology it questions the autonomous subject as a ground for political action and criticality. This is done by challenging language as a vehicle for individual expres

ARCHITECTURAL OBJECTS AND SYSTEMS BUILDING

In this paper we explore the concept of “architectural object” as a representation of a real “situation” involving people, behavior, experience and environment. The purpose is to define a selection of possible configurable architectural objects that reflect the variability of situations possible to achieve using an industrialised building system. The paper presents a theoretical foundation for org

Controversy and epistolary mediation in the construction of phonetic knowledge

As scientific knowledge grows, it often engenders controversy. The aim of the particular case of controversy studied here, in a series of letters exchanged between two phoneticians, is to capture vacillations of a discipline (phonetics) and its “actants” (phoneticians and their equipment), described at a key moment in the history of the discipline (an historical “turning point”), i.e. when phoneti
