Field Demonstration of Heat Technology to Mitigate Heat Sinks for Drywood Termite (Blattodea: Kalotermitidae) Management

With heat treatments to control drywood termites (Blattodea: Kalotermitidae), the presence of heat sinks causes heat to be distributed unevenly throughout the treatment areas. Drywood termites may move to galleries in heat sink areas to avoid exposure to lethal temperatures. Our studies were conducted in Crytotermes brevis-infested condominiums in Honolulu, Hawaii to reflect real-world condominium scenarios; either a standard heat treatment performed by a heat remediation company, or an improved heat treatment was used. For improved treatments, heated air was directed into the toe-kick voids of C. brevis infested cabinets to reduce heat sink effects and increase heat penetration into these difficult-to-heat areas. Eight thermistor sensors placed inside the toe-kick voids, treatment zone, embedded inside cabinets’ sidewalls, and in a wooden cube recorded target temperatures of above 46 °C or 50 °C for 120 min. Pre-treatment and follow-up inspections were performed at 6 months posttreatment to monitor termite inactivity using visual observations and by recording the numbers of spiked peaks on a microwave technology termite detection device (Termatrac). In improved treatment condominiums, significantly higher numbers of spiked peaks were recorded at pre-treatment as compared to 6 months posttreatment. Efficacious heat treatment protocols using the improved methods are proposed.

We Are Mathematical Beings

In this mathematical-poetical text, the author posits mathematical thought as fundamental to concepts of self and world. Mathematics is not something exterior to be learned, but basic to daily life. For example, object permanence is an abstract concept of multiple perspectives compiled in to the idea of one stable object. Such abstraction is mathematics. These concepts exist both socially and materially. A wooden cube is both a social concept and a material object. We exist in a mathematically determined world. We use mathematics to enact new reals. This is so common that often we are unaware of it.

Heat Technology Aiming to Mitigate Structural Heat Sinks for Drywood Termite (Blattodea: Kalotermitidae) Management

With heat treatments to control drywood termites (Blattodea: Kalotermitidae), the presence of heat sinks, which have insulating properties, causes heat to be distributed unevenly throughout the treatment areas. Drywood termites may move to galleries in heat sink areas to avoid exposure to lethal temperatures. To mitigate heat sink effect, studies were conducted in Crytotermes brevis-infested homes in Honolulu, Hawaii to reflect real-world scenarios; either a standard heat treatment performed by a heat remediation company or improved heat treatment methods were used. For improved treatments, heated air was directed into the toe-kick voids of cabinets to reduce heat sink effects. Eight thermistor sensors were placed inside toe-kick voids, in the treatment zone, embedded inside cabinets or the sidewall, or in a wooden cube to monitor internal and ambient temperatures to ensure sufficiently high heat reached all areas. Target temperatures above 46 °C or 50 °C were recorded in all areas for 120 minutes. A pretreatment inspection was conducted, and follow-up inspections were performed at 6 months posttreatment to confirm termite inactivity using visual observations and a Termatrac device. In improved treatment homes, no termite activity was found after treatment. Efficacious heat treatment protocols for structures using the improved method are proposed.

Fermat`s Last Theorem Proof on Six Faces of a Wooden Cube

Fermat's Last Theorem has been proved on the basis of school Physics, Mathematics, analytical Geometry. The main conceptions of the proof one can write on a math toy in the form of a wooden cube for children. Six faces of the cube are enough to deliver the main ideas of proof.

Examining Functional Spatial Perception in 10-Year-Olds and Adults

This study examined a specific type of spatial perception, functional spatial perception, in 10-year-old children and adults. Functional spatial perception involves anticipating actions made with objects to fulfill a function, or, in this case, fitting objects through openings. We examined accuracy, sensitivity, and consistency in participants' abilities to adjust a window to the smallest opening through which a small wooden cube would fit. Success at this task requires accounting for the dimensions of both the object and the opening. In life circumstances, poor decisions at similar tasks may result in injury, frustration, or property damage. As much previous work in this area included very young children and adults, we sought to determine whether older children (10-year-olds) would show adult-like skills. Ten-year-old participants were as equally accurate and sensitive as adults, and both groups left a safety margin in performing this task; but we found that adults made more consistent judgments than 10-year-olds. There are developmental implications for these findings, given daily real-life needs to accurately gauge functional spatial relations and navigate objects in real life.

Effect of Instructions on a Creative Task: Discipline and Form in Hand Sculptures

How do different limitations which are imposed on a person affect the quality of his creative product? Different freshman sections in architecture were randomly given different limitations for their first three-dimensional assignment which was to produce a handcarving from a 6-in. wooden cube. The limitations were in the number of edges to be left intact: 0, 3, 6, 9, and 12. As predicted, the products differed in relation to the limitations; however, more specific predictions about which carvings would excel were only partially confirmed because, it is speculated, the staff had focused more on the students' frustrations than on some inherent properties of the task. The data do fit an interpretation which relates the architectural concepts of object, void, and their relationships to the “new look” in motivation wherein focus is on the relationship between stimulus complexity and the person's needs and abilities.
