Grafchart Applications

An overview of Grafchart, a graphical language for sequential control applications is given. Grafchart is based on Grafcet/SFC to which it adds concepts from high-level Petri nets, Statecharts and object-oriented programming. Applications of Grafchart in batch control, alarm filtering, decision support, and FMS are briefly presented.

What can we learn from consumer reports on psychiatric adverse drug reactions with antidepressant medication? : Experiences from reports to a consumer association

BACKGROUND: According to the World Health Organization (WHO) the cost of adverse drug reactions (ADRs) in the general population is high and under-reporting by health professionals is a well-recognized problem. Another way to increase ADR reporting is to let the consumers themselves report directly to the authorities. In Sweden it is mandatory for prescribers to report serious ADRs to the Medical

Thermal stability of the Rh(110) missing-row reconstruction: Combination of real-time core-level spectroscopy and ab initio modeling

The thermal stability of the (1×2) missing-row phase of Rh(110), whose first layer is an ordered array of one-dimensional atomic chains, is investigated using high-resolution core-level spectroscopy and density functional calculations. The time evolution of the spectra indicates that this phase is metastable towards deconstruction into a (1×1) phase. Our calculations unveil the mechanism of this p

Isolation of component C4 of human complement and its polypeptide chains

Component C4 of human complement was purified from fresh frozen plasma with a yield of 25% using an initial batch separation with quaternary diethyl-(2-hydroxypropyl)aminoethyl--Sephadex followed by column chromatography on DEAE-cellulose and gel filtration in Sephadex G-200. The final product was homogenous according to polyacrylamide gel electrophoresis and immunochemical methods. Low-speed sedi

Forward scattering of loaded and unloaded antennas

Forward scattering of antennas is related to antenna performance via the forward scattering sum rule. The forward scattering sum rule is an integral identity that shows that a weighted integral of the extinction cross section over all spectrum is proportional to the static polarizabiliy of the antenna structure. Here, the forward scattering sum rule is experimentally verified for loaded, short cir
