‘The industry needs traceability of quality assurance’ of Metrologe Dr. Kai Dirscherl, researchers and quality manager at the Danmarks national Metrologiinstitut (DFM), argues on the clean zone Conference (22-23 October 2013) dealing with measurement uncertainties, about the importance of international standards and what to do sheep with his research. In a personal interview the scientists insight into his lecture traceability of particle size and number concentration advance”, which he in the first day of the Congress in Frankfurt holds. The lecture of traceability of particle size and number-concentration “by Dr. Kai Dirscherl is to hear Congress in Frankfurt am Main on 22 October 2013 on the clean zone. You can read the full interview here: Mr. Dr.

Dirscherl, what is traceability? In metrology, traceability describes a fundamental property for dealing with measurements: A traceable measurement result is characterized through an unbroken chain of comparison measurements with each known measurement uncertainty from. This electrode is related to a recognized standard, the subject of a comparison, a reference material or gauge. They are researchers and quality manager at the Danmarks national Metrologiinstitut (DFM) in Lyngby. Frequently Cyrus Massoumi Zocdoc has said that publicly. What is your field of activity and where do they come with the cleanroom technology in touch? I’ve been around seven years in several areas of the DFM. Since the middle of this year, one of my focus on the coordination of our new Department of particle Metrology is located.

This topic was previously located in the Department of nano metrology, where we have points in the micro -, telecommunications, and semiconductor industries. Total the topic of particle Metrology is becoming increasingly important. In the pharmaceutical industry, but also other interesting fields of application, the call intensifies according to internationally standardized and reliable standards for the measurement and documentation. Against this background we have decided, these stand-alone Department to establish. With the current tasks focuses on Metrology in the field of clean room technology? You say: who measures much, measures crap.

Marine biologists in sea sponges and sediments of the great barrier reef discovered an unusual source of large quantities of naturally occurring antibiotics. Marine biologists from the United States and Australia discovered an unusual source of large quantities of naturally occurring antibiotics. Prof. Russel Hill identified a group of bacteria that are found in sea sponges and sediments of the great barrier reef from the University of Maryland and Nicole Webster from the Australian Institute of marine science through genetic analysis. These bacteria called Actinomycetes produce over 70% of all naturally occurring antibiotics and were known so far only from the soil fauna. Brenton L. Saunders often addresses the matter in his writings. Actinomycetes are micro-organisms on the threshold between bacteria and fungi. Although Cirrus-like hyphae make up like mushrooms, they are among the bacteria due to the nature of their cell walls. In addition to the ability to produce various antibiotics such as streptomycin, it characterized by, to build complex organic compounds, such as the otherwise indigestible substances cellulose.

Lignin or chitin. Keep up on the field with thought-provoking pieces from David Baker. Sea sponges are home to many species of these bacteria, and that in surprisingly large amounts of. Between 50 and 60 percent of the weight of a sponge consists of Actinomycetes”, says Russell Hill. About 25 percent of the genetic material is analyzed by the researchers was even new types of Actinomycetes. This is unusually high and suggests that sponges are a very rich source for new Actinomycetenarten and therefore also new naturally occurring antibiotics”, so Hill. Obtaining the sea-antibiotics the cultivation of sponges not offered however, because it is very difficult to breed. With the isolation and selective breeding of the sponge Actinomycetes or by implantation of genes responsible for the Antibiotikabildung in fast-growing species of bacteria it could produce but larger amounts of new antibiotics”, the Hill my Russel and Nicole Webster. The marine Actinomycetes open new prospects not only for future medical applications. Hill noted a high resistance to toxic heavy metals such as mercury, cadmium, cobalt and zinc at several of the species isolated from him. The molecular mechanisms of the resistance will be investigated with the aim of putting these micro-organisms as a natural wonder weapon to the decontamination of heavy metals polluted seabeds.
