Wooden pallets are the largest single use of sawn hardwood logs in the USA. Unfortunately, millions of wooden pallets are discarded annually due to damage or because their low cost makes them readily disposable. High quality wooden pallets, on the other hand, promote longevity and re-use. However, building durable pallets requires high quality pallet parts. Because manual grading and sorting of...

Young children often build various structures with wooden blocks; structures that are often used for pretend play, subtly improving children’s creativity and imagination. Based on a traditional Japanese wooden block toy, Tsumiki, we propose a novel interactive toy for children, named “TSU.MI.KI”, maintaining the physical assets of wooden blocks and enhancing them with automation. “TSU.MI.KI” co...

Currently hydrogen cyanide (HCN) is industrially produced in the Czech Republic (Lucebni zavody Draslovka Kolin) and is extensively used for Czech mill fumigation. Therefore we evaluated the potential of HCN fumigant for treatment of wooden transport packages (pallets). We tested the penetration of HCN trough wooden pallet materials using gas chromatography. The preliminary results on biologica...

The dynamical responses of railway track has been carried out by different ways. In this work, developing an analytical model for the ballasted which includes two rails connected to sleeper, a fast method calculated dynamic is presented. rail modelled as infinite beams posed on periodically supports are rested viscoelastic foundation. We consider equation in steady-state subjected moving loads....

To study the mechanical characteristics of ballasted bed under dynamic stability, a three-dimensional discrete element model with 1000 mm × 700 550 is established based on method. Meanwhile, simulation test bench same size built for analysis and experimental research. The variation law trend settlement, lateral resistance, compactness different excitation frequencies are analyzed comprehensivel...

Objective The aim of this study was to evaluate the usefulness of reconstructed computed tomography (CT) images using OsiriX software in detecting wooden and bamboo foreign bodies. Methods Four sizes of wet and dry wooden and bamboo foreign bodies were selected to be analyzed. Those in the air and in the head of edible swine were scanned with a multidetector row CT scanner. The images were ev...

DESCRIPTION A 39-year-old man presented with a 5-day history of increasing left eye swelling and erythema, after a palm tree branch struck his face.

The saccule is known to play an important role in hearing in fishes. In this study we investigated spatial frequency selectivity of single saccular afferents in a teleost fish (the sleeper goby, Dormitator latifrons) to acoustic particle motion at 50-400 Hz. Saccular afferents have similar distributions of best sensitivity (-90.0 to -54.8 dB re. 1 g, mean +/- s.d.=-81.1+/-8.0 dB) and characteri...

An analysis of group influence processes indicates that the functional relationship between attraction to a group and influence exerted by the group depends on the importance to the individual member of any freedom that is threatened by group pressure to conform. This proposition was tested by an experiment in which the effect of group conformity pressure on public and private opinions was meas...
