The Pediatric Symptom Checklist (PSC) is a 35-item parent-report questionnaire designed to identify children with difficulties in psychosocial functioning. Its primary purpose is to alert pediatricians at an early point about which children would benefit from further assessment. [ 1 ]
A LaMont boiler is a type of forced circulation water-tube boiler [1] in which the boiler water is circulated through an external pump through long closely spaced tubes of small diameter. The mechanical pump is employed in order to have an adequate and positive circulation in steam and hot water boilers.
A chiller boiler system is a hydronic system. It uses water instead of air to heat and cool a structure. A properly designed hydronic system is usually more efficient than a standard forced air system. [1] Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones ...
A duplex steam pump has two sets of steam and water cylinders. They are not physically connected but the steam valves on the first pump are operated by the movement of the second pump's piston rod, and vice versa. The result is that there are no "dead spots" and the pump is always self-starting. [2]
The Child Behavior Checklist (CBCL) is a widely used caregiver report form identifying problem behavior in children. [ 1 ] [ 2 ] It is widely used in both research and clinical practice with youths. It has been translated into more than 90 languages, [ 3 ] and normative data are available integrating information from multiple societies.
A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler. This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler. In some forced circulation boilers, the water is circulated at twenty times the rate of evaporation. [1]
A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.
The most common type of electrode boiler pumps water from the lower part of the vessel to an internal header that has nozzles that allow the water to flow to electrodes. Generally the working pressure is maintained at 10 bar. If more pressure is needed (more steam) the controls speed up the pump to increase flow through additional nozzles.
