Is E coli a cloning vector? There are many types of cloning vectors, but the most commonly used ones are genetically engineered plasmids. Cloning is generally first performed using Escherichia coli, and cloning vectors in E. coli include plasmids, bacteriophages (such as phage λ), cosmids, and bacterial artificial chromosomes (BACs). What is the size of […]
What is the maximum stress concentration factor?
What is the maximum stress concentration factor? A stress concentration factor is the ratio of the highest stress (smax)) to a reference stress (s) of the gross cross-section. As the radius of curvature approaches zero, the maximum stress approaches infinity. Note that the stress concentration factor is a function of the geometry of a crack, […]
Does air entrainment affect concrete strength?
Does air entrainment affect concrete strength? Intentionally entrained air voids improve the resistance of concrete to damage from cycles of freezing and thawing. Any air voids reduce the strength of concrete, with about a 5% reduction in strength for each 1% increase in the volume of air voids. Air voids, however, also improve the workability […]
How the RLC series circuit behaves for the frequencies above and below the resonant frequencies?
How the RLC series circuit behaves for the frequencies above and below the resonant frequencies? How the RLC series circuit behaves for the frequencies above and below the resonant frequencies. For frequencies below resonant frequency, the capacitive reactance is more than the inductive reactance. Therefore the equivalent reactance is equal to capacitive and the circuit […]
How do you know if a process is statistical control?
How do you know if a process is statistical control? Control charts are used to determine whether a process is in statistical control or not. If there are no points beyond the control limits, no trends up, down, above, or below the centerline, and no patterns, the process is said to be in statistical control. […]
What are the factors of difficulties in goal settings?
What are the factors of difficulties in goal settings? Barriers to goal setting and planning could be external and internal factors….6 Barriers to Goal Setting in Organization Inappropriate Goals. Improper Reward System. Dynamic and Complex Environment. Reluctance to Establish Goals. Resistance to Change. What are the three main components of goal setting theory? What is […]
What is cold junction in thermocouple?
What is cold junction in thermocouple? The point where the thermocouple is connected to the copper connections of an instrument is the cold junction. The cold junction circuit compensates for this missing voltage by adding (or subtracting if the cold junction temperature is below the ice point) to the measured voltage coming from the hot […]
How can deadlock be prevented in hold and wait condition?
How can deadlock be prevented in hold and wait condition? 2 Hold and Wait. To prevent this condition processes must be prevented from holding one or more resources while simultaneously waiting for one or more others. There are several possibilities for this: Require that all processes request all resources at one time. How can we […]
How do you find the critical depth rectangular channel?
How do you find the critical depth rectangular channel? The critical depth for a rectangular channel can be calculated from the fact that the Froude number is equal to one at critical flow conditions. For a rectangular channel , this fact leads to the equation: Vc/(gyc)1/2 = 1, where the subscript c is used to […]
