TECHNICAL WORD OF THE WEEK resistance (noun) TRANSLATIONS English - German: Widerstand, Widerstandsfähigkeit, Beständigkeit English - Spanish: resistencia English - French: résistance English - Italian: resistenza English - Portuguese: resistência English - Finnish: vastus DEFINITIONS The degree to which a material or device opposes the passage of an electric current, causing energy dissipation. (Source: Concise Oxford Dictionary) The act or an instance of resisting or the capacity to resist. (Source: thefreedictionary.com) The power or capacity to resist; especially: the inherent ability of an organism to resist harmful influences (as disease, toxic agents, or infection) (Source: merriam-webster.com) EXAMPLES OF USE Resistance is the property of a component which restricts the flow of electric current. Energy is used up as the voltage across the component drives the current through it and this energy appears as heat in the component. http://www.kpsec.freeuk.com/resistan.htm An electron traveling through the wires and loads of the external circuit encounters resistance. Resistance is the hindrance to the flow of charge. http://www.physicsclassroom.com/class/circuits/u9l3b.cfm Antibiotic resistance is a worldwide public health problem that continues to grow. It occurs when strains of bacteria in the human body become resistant to antibiotics due to improper use and abuse of antibiotics. http://www.acponline.org/patients_families/diseases_conditions/antibiotic_resistance/ Abresist Kalenborn provides wear resistant linings with excellent abrasion and impact resistance – specifically constructed for use wherever wear and abrasion are a problem. http://www.abresist.com/ Resistance thermometer sensors use a wire, film, chip or bead whose electrical resistance changes with temperature. The resistor is connected to a measuring bridge or voltmeter, whose output is processed to obtain the temperature. http://bit.ly/Jrn7bn Herbicide resistance is the genetic capacity of a weed population to survive a herbicide treatment that, under normal use conditions, would effectively control that weed population. Herbicide resistance is an example of evolution happening at an accelerated pace and an illustration of the "survival of the fittest" principle. http://www.omafra.gov.on.ca/english/crops/facts/01-023.htm This technical document considers a number of test methods for assessing floor slip resistance and describes those used by HSE/HSL in more detail. It is intended for organisations which need to perform accurate measurements of floor slipperiness, such as manufacturers and research and testing bodies. http://www.hse.gov.uk/pubns/web/slips01.pdf Air resistance also acts as a frictional force, slowing objects down; for example, air resistance makes cars less fuel efficient. But it can also be helpful in many situations. Without air resistance neither planes nor helicopters could fly.... http://nautilus.fis.uc.pt/personal/pvalberto/aulas/cef_mestrado/Air.Resistance.pdf Reducing the frictional resistance by air or gas lubrication (air chambers, micro bubbles) in combination with water repellent coatings is an attractive option for enhancing a ship sustainability. http://www.cmti.nl/?p=1028&lang=en The interactive estimating tool for low slope roofs allows for simple plenum spaces above drop ceilings. Include the small thermal resistance that they add in the thermal resistance of the roof assembly. Simple plenum spaces can include well-insulated supply and return air ducts for the building conditioning system. http://www.duracoolinc.com/effect_of_solar_radiation.html WORD FAMILY resist - verb resistant - adjective resistive - adjective resistor - noun resistibility – noun resistance - noun Synonyms - combat, counteraction, fight, impedance, obstruction, resistant Antonyms - acceptance, submission VIDEOS New Warnings About Over-Use of Antibiotics http://abcnews.go.com/WNT/video/besser-antiboiotics-resistance-warnings-health-15946642 Malaria fight 'badly compromised' by resistance http://www.bbc.co.uk/news/health-17635512 Diabetes: understanding insulin resistance http://www.youtube.com/watch?v=5x5MJAulQ9I Extreme Engineering: Air Resistance http://videos.howstuffworks.com/discovery/29152-extreme-engineering-air-resistance-video.htm ESD Test Equipment - Volume Resistance http://www.prostatcorp.com/volumeresistance/ Just How Water Resistant is the Samsung Rugby Smart Android Smartphone? http://www.youtube.com/watch?v=AX2lxVbrJmQ Raex wear-resistant and Optim high-strength steels http://www.youtube.com/watch?v=P0reEHbmlzo Resistance Tester http://www.stats-consult.com/electrical-testing-equipment/resistance-tester Electrical Resistance http://www.youtube.com/watch?v=PldWJ9MWQ1k
