What are the 5 steps in adaptive immunity? Steps in adaptive immune process STEPS IN ADAPTIVE RESPONSE 1.Monocytes “eat” pathogen 2. Reveals part of antigen on cell surface 3. Receptor on helper T-cell identifies the antigen 4. STEPS IN ADAPTIVE RESPONSE 5. Killer T-cells become activated to attack specific pathogen 6. B-cells become activated and […]
Are all new furnaces High Efficiency?
Are all new furnaces High Efficiency? In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. High efficiency furnaces offer 90% or more AFUE. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% furnace. What […]
How is capillary effect affected by the contact angle?
How is capillary effect affected by the contact angle? Capillary action can also be to understood in terms of capillary pressure. Pcap = 2 γlv *cos(θ) / r. From this, we see that the lower the contact angle (the more hydrophilic the pore) the higher the capillary pressure and thus the the stronger the capillary […]
What are the main parts of a clutch assembly?
What are the main parts of a clutch assembly? The modern clutch has four main components: the cover plate (which incorporates a diaphragm spring), the pressure plate, the driven plate, and the release bearing. What parts are included in a clutch kit? Summary. A clutch kit is a selection of parts that are used to […]
What are the three main types of control systems?
What are the three main types of control systems? Three basic types of control systems are available to executives: (1) output control, (2) behavioural control, and (3) clan control. Different organizations emphasize different types of control, but most organizations use a mix of all three types. Which is the good features of control system? A […]
What happens when thermosets are heated?
What happens when thermosets are heated? Thermoset polymers do not soften when heated because the molecules are cross-linked together and remain rigid. The chemical bonding formed within a polymer, and the shape of the resulting polymer, affect its properties. Which is thermosetting polymer? A thermosetting polymer, resin, or plastic, often called a thermoset, is a […]
What are the different losses that occur in a steam turbine?
What are the different losses that occur in a steam turbine? Losses due to leakage :- In Impulse turbine, leakage loss occurs between the shaft, bearings, nozzles and stationary diaphragms. For Reaction turbine, it may occur at the blade tips. This loss is due to the leakage of steam on each stage of the turbine. […]
How do you find slope angle of a river?
What causes electric shock?
What causes electric shock? An electric shock happens when someone comes into contact with any source of electrical energy. This can be due to a lightning strike or due to a man-made source of electricity such as electrical circuits or appliances. The shock occurs when the electricity flows through the body. What three factors determining […]
What is the maximum dry unit weight to which this soil can be compacted without change in its moisture content?
What is the maximum dry unit weight to which this soil can be compacted without change in its moisture content? From this figure the maximum dry unit weight is approximately 16.6 kN/m3. The corresponding optimum moisture content is 20%. How do you calculate maximum dry unit weight of soil? The maximum dry unit weight is […]
