Abstract:
An investigation was made to determine the relative performance of some chemicals against growth of blue stain fungus and attack of pinhole borer on freshly‑sawn coconut timber during the drying process. The fungicides used were Farmay Plus, Azaconazole and the standard chemical combination of Sodium Pentachlorophenate, BHC and Borax Pentahydrate. Cislin, an insecticide, was mixed with either Farmay Plus or Azaconazole solution.
 
 Results after 12 weeks of air drying showed that all fungicides failed to give the desired protection against blue staining. Performance ratings of planed

Abstract:
A semiochemical-based attractant for Euplatypus parallelus was identified and field-tested. Analyses of headspace volatile extracts of conspecific males revealed the presence of 1-hexanol along with lesser amounts of 3-methyl-1-butanol, hexyl acetate, 1-octanol and trans-geraniol, which were not found in equivalent extracts from females. Emission of 1-hexanol coincided with the emergence of adults of both sexes during afternoon hours. A synthetic blend of these compounds, with and without ethanol, was tested in the field. The blend alone attracted a small number of females and no males. Ethano

Abstract:
Stephen L. Wood re-defined Platypus such that its members are native to realms outside of the Americas and transferred most Neotropical species out of that genus. I have come across 44 species that still remain, though, and these are treated here. In total, I report 49 new generic assignments, 30 of which are transfers out of Platypus. I propose 22 new synonymies, eight of which are Platypus species that are synonymized with previously transferred species. Six Neotropical species are left in Platypus, for reasons detailed in the text. These taxonomic acts affect the compositions of eight of th

Pinhole borers (Coleoptera: Curculionidae, Platypodinae) are ecologically important and evolutionary unique taxa of economic significance. They are the oldest known insect lineage that cultivates fungi, commonly referred to as ambrosia fungi, within galleries excavated into the heartwood of trees. Most species of pinhole borers inhabit dead or dying trees, however, several species attack living trees, which can have detrimental effects on these hosts. For example, wilt disease is a common disease of trees caused by fungal pathogens transmitted by some pinhole borer species. These beetle specie

Abstract:
A three-dimensional (3-D) electromagnetic field simulation is used to model the propagation of extreme ultraviolet (EUV), 13 nm wavelength, light through sub-1500 Å diameter pinholes in a highly absorptive medium. Deviations of the diffracted wavefront phase from an ideal sphere are studied within 0.1 numerical aperture, to predict the accuracy of EUV point diffraction interferometers used in at-wavelength testing of nearly diffraction-limited EUV optical systems. Aberration magnitudes are studied for various 3-D pinhole models, including cylindrical and conical pinhole bores.

Abstract:
Planet-to-planet load sharing is a major design and manufacturing tolerancing issue in planetary gear sets. Planetary gear sets are advantageous over their countershaft alternatives in many aspects, provided that each planet branch carries a reasonable, preferably equal, share of the torque transmitted. In practice, the load shared among the planets is typically not equal due to the presence of various manufacturing errors. This study aims at enhancing the models for planet load sharing through a three-dimensional formulation of N-planet helical planetary gear sets. Apart from previous models,

Abstract The loss of containment in liquid pipelines is a significant concern for pipeline operators, service providers, and regulators. Estimating the potential spillage volume at a designated pipeline location is critical for societal risk analysis, environmental impact assessment, and emergency response planning. The total spillage volume, after loss of containment, in each scenario consists of two parts: (a) the spill volume during operation while the pumps are active, and (b) the gravitational spillage volume after the pumps are shut down.
