Abstract: The invention relates generally to building construction, and more particularly to studs for use in wall panels used in the construction of foundation walls and upper floor exterior walls. The invention provides a structural wall system to support building loads and lateral earth pressure from adjacent ground, said system comprising a wall assembly using plurality of studs preferably formed from metal located side by side and each having a cross section comprising an orthogonal lip section with interior flange section, a web section, and an exterior diaphragm section orthogonal to the web section and having a first recessed shoulder on the open distal end and a second recessed shoulder on the bend line integral with the web section. The wall system may be assembled using a standard steel channel as a starting point. The stud diaphragm of the present invention extends laterally from the web portion with the distal edge to be aligned with and fastened to the standard steel channel.

Abstract: An apparatus for killing insects, the apparatus including one or more host targets for attracting flying insects using one or a combination of ultraviolet light, halogen light, heat, and chemical sensory emissions attractive to flying insects; upper and lower housings connected in a manner to establish a vertical separation to accommodate an air column open to the atmosphere; and one or more insect capture assemblies located to receive the air current having a mesh or other means dimensioned to separate insects from the air current of the air column. The air column is generated by one or more air current generators in the upper and/or lower assemblies to produce a uniform air current open to the atmosphere and flowing vertically at an increased relative speed to the atmosphere thereby creating a zone of differential pressure where the pressure is lowest at the interface between the air column and the atmosphere and increases to atmospheric pressure radially at a distance away from the air column.
