Which plasmid vector is smaller in size? The plasmid pICOz is even smaller (only 1185 bp). It was constructed by replacing the ampicillin resistance gene in pUCmu by the zeocin resistance gene. The plasmids pICOz (LMBP 11103), pUCmu (LMBP 9329) and pUCmini (LMBP 9221) are available at the BCCM/GeneCorner Plasmid Collection (previously BCCM/LMBP). What is […]
How does microstructure affect mechanical properties?
How does microstructure affect mechanical properties? The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low temperature behaviour or wear resistance. How can alloying alter the mechanical properties of metals? These changes will add strength, make alloys more malleable, […]

What is scanning while driving?
What is scanning while driving? Scanning is a way to view the “total traffic scene” as you drive. It prevents tunnel vision, which can isolate you from what is going on in the distance as well as all around your vehicle. See also: 10 Strategies for Highway Driving. What should you look for when scanning […]
What are the advantages and disadvantages of composite materials?
What are the advantages and disadvantages of composite materials? 1.5 Advantages and Disadvantages of Composite Materials • The advantages of composites are many, including lighter weight, optimum strength and stiffness, improved fatigue life, corrosion resistance, and good design practice, reduced assembly costs due to fewer detail parts and fasteners. What are the characteristics of composites? […]
How are actuators used?
How are actuators used? An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a “mover”. When it receives a control signal, an actuator responds by converting the source’s energy into mechanical motion. How do […]
Do you lubricate fuel injector O-rings?
Do you lubricate fuel injector O-rings? Yes you have to lube them with something! Does polarity matter on fuel injectors? The fuel injectors are elctromagnetic solenoids so polarity shouldn’t be an issue. You can test them easy enough by quickly tapping the wires to the battery terminal – you should hear them click if they […]
