This study evaluated several conventional and novel emission control technologies that have been used or could be used to treat styrene emissions from open molding processes in fiberglass-reinforced plastics/composites (FRP/C) and fiberglass boat building facilities. Control costs for these conventional and novel technologies were developed and compared for three hypothetical plant sizes. The r...

By changing the N-donor groups of benzonitrile-based reactants, three novel isopolymolybdate-based compounds, [Cu(DBIBA)3][δ-HMo8O26] (1), [Cu(H2O)(DIBA)(DIBAH)(γ-HMo8O26)]·2H2O (2), and [CuI(DTBA)(Mo2O6)] (3) (HDBIBA = 3,5-di(benzoimidazol-1-yl)benzoic acid, HDIBA = 3,5-di(1H-imidazol-1-yl)benzoic acid and HDTBA = 3,5-di(1,2,4-triazol-1-yl)benzoic acid) were synthesized, in which the benzene c...

Building energy models usually employ a constant, room-temperature-measured value for the thermal resistance of fiberglass roof insulation. In summer, however, the mean temperature of roof insulation can rise significantly above room temperature, lowering the insulation’s thermal resistance by 10% to 20%. Though the temperature dependence of the thermal resistance of porous materials like fiber...

This report presents an assessment of VOC emissions from fiberglass boat manufacturing. First, a description of the industry structure is presented. This includes estimates of the number of facilities, their size, and geographic distribution. The fiberglass boat manufacturing process is then described along with the sources and types of VOC emissions. Model plants representative of typical faci...

BACKGROUND The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw. METHODS Casts of uniform thickness were applied...

BACKGROUND High-resolution peripheral quantitative computed tomography (HR-pQCT) is a promising tool to assess the fracture-healing process at the microscale in vivo. Since casts are often used during fracture treatment, they might affect the assessment of bone density, microarchitectural, and biomechanical parameters and the short-term reproducibility of those parameters, e.g., as a result of ...

background: the witches’ broom disease of lime caused by candidatus phytoplasma aurantifolia, is the most devastating disease of acidian lime in the southern parts of iran. objectives: at present, no effient method has been developed for controlling the disease, therefore quarantine approaches such as early detection and subsequent eradication of infected trees is very important. toward this ...

We present measurements of the low-temperature thermal conductivity of a number of polymeric and composite materials from 0.3 to 4 K. The materials measured are Vespel SP-1, Vespel SP-22, unfilled PEEK, 30% carbon fiber-filled PEEK, 30% glass-filled PEEK, carbon fiber Graphlite composite rod, Torlon 4301, G-10/FR-4 fiberglass, pultruded fiberglass composite, Macor ceramic, and graphite rod. The...

This work presents the quadrature sinusoidal oscillator using two Voltage Differencing-Differential Input Buffered Amplifiers (VD-DIBAs), resistors, and capacitors. The VD-DIBA is an electronically controllable active building block with high input low output impedances that can connect to other circuits directly without buffers. With these distinguished features, employed in this design. propo...

Contact with the soil, fomites or hands contaminated with the animals’ feces favors accidental human infection either through ingestion of Toxocara canis embryonic eggs, resulting in Visceral Larva Migrans (VLM) syndrome (Coelho et al., 2001), or through percutaneous penetration of Ancylostoma caninum and Ancylostoma braziliense infective larvae, causing Cutaneous Larva Migrans (CLM) Syndrome (...
