 The paper presents a multimedia interactive course for teaching the operation of communications and audiovisual equipment. The objectives of the course are the following: providing a tool for undergraduate students which enables the self-learning of the equipment basis and operation, helping the students to get used to the laboratory equipment and trying to improve their understanding of the ...

A set of instruments and specialized equipment is necessary to equip a laboratory to work with DNA. Reducing the barrier to entry for DNA manipulation should enable and encourage new labs to enter the field. We present three examples of open source/DIY technology with significantly reduced costs relative to commercial equipment. This includes a gel scanner, a horizontal PAGE gel mold, and a hom...

The ICEM power testing laboratory is designed mainly for power testing the electrical power system elements and partly for voltage testing of the middle-voltage equipment. The paper deals with the theory of power testing and operation of the ICEM power testing laboratory for high currents. A brief presentation of its electrical equipment and is shown. Calculation of short circuits and voltage d...

background: the aim of this study was to evaluate risk of needle stick and sharp injuries (nsi) and exposure to blood borne pathogens, among laboratory technicians. methods: 213 self-reporting questionnaires were distributed among the laboratory technicians who were working at three educational hospitals in tehran. a total of 193 laboratory personnel completed the questionnaire. results: 69.9% ...

OBJECTIVE Analysing the fundamental methodological aspects which should be considered when drawing up calibration procedure for electro-medical equipment, thereby permitting international standard-based accreditation of electro-medical metrology laboratories in Colombia. METHODS NTC-ISO-IEC 17025:2005 and GTC-51-based procedures for calibrating electro-medical equipment were implemented and t...

Humans adapt their risk-taking behaviour based on perceptions of safety; this risk compensation phenomenon is typified by people taking more risks when using protective equipment. Existing studies have looked at people who know they are using safety equipment, and have specifically examined changes in behaviours against which that equipment might reduce risk. We demonstrate risk-taking increase...

I recall someone once saying to me that “perception is reality.” But say this to scientists or engineers who need to take experimental data at midnight because their lab equipment is sensitive to even the minutest vibration and they may tell you otherwise. The reality is that imperceptible vibrations can and do impact sensitive experiments, and identifying the sources and selecting the proper e...

In our days, interactive multimedia based client equipment (desktop), a palmtop or an equipment capable of mobile sound transmission (mobile phone, communicator) are all, though in different ways, suitable for interactive (multimedia based) knowledge transfer. The aim of developers is to pass the same knowledge no matter through what kind of medium. The practical realization of such multifuncti...
