A new apparatus for measuring both the thermal conductivity and thermal diffusivity of fluids at temperatures from 220 to 775 K at pressures to 70 MPa is described. The instrument is based on the step-power-forced transient hot-wire technique. Two hot wires are arranged in different arms of a Wheatstone bridge such that the response of the shorter compensating wire is subtracted from the respon...

Abstract The moisture contents of sugi ( Cryptomeria japonica ), todomatsu Abies sachalinensis ) and hinoki Chamaecyparis obtusa logs were estimated using a method content estimation proposed in our previous study. In the course estimation, it was revealed that regression line correlation between specific dynamic Young’s modulus E / ρ tangent loss (tan δ green wood different from moisture-condi...

The ease and convenience of a hot-wire cutter for the separation of wells from PVC radioimmunoassay trays has been demonstrated.' In constructing a similar apparatus, it was felt that a worthwhile simplification could be achieved by arranging to push the PVC tray past a fixed hot wire. The wire can simply be held under spring tension, and the springloaded telescopic arm previously employed' be ...

This paper concerns the reliability of thermosonically bonded 25μm Au wires in the combined high temperature with vibration conditions, under which the tests have been carried out on wire bonded 40-pin Dual-in-Line (DIL) High Temperature Co-fired Ceramic (HTCC) electronic packages. Mechanical, optical and electrical analysis has been undertaken in order to identify the failure mechanisms of bon...

laboratory and field experiments were conducted to determine the efficacy of some insecticides on the control of sarta longhorned beetle, aeolesthes sarta solsky adults and larvae. in the laboratory, three pairs of mated and non-oviposited adults were released on the logs of field elm, ulmus minor mill that had been treated with chlorpyrifos, carbaryl, permethrin or imidacloprid. in the field e...
