The article presents the results of experimental and theoretical research on application of ?DD-diagrams for estimation of admissibility of defects in ultrasonic control of the rolled wheel centers in radial direction. The application of this method will ... see more

Communities in Kalimantan areas need wood for building materials. They use Tumeh wood (Combretocarpus rotundatus Dans) because of its found abundantly in forest area in Central Kalimantan. Tumeh is a kind of pioneer. Wood parts affect the quality of wood.... see more

When determining the mechanical properties of ring specimens, a feature of a uniaxial (standard) loading scheme is that the method of applying a load to a specimen is somewhat remote from that to which the pipe walls can be subject in real operating condi... see more

This study analyses the variation of main physical-mechanical properties of wood along the longitudinal and radial directions of the tree for Abies alba Mill. growing in the Spanish Pyrenees. Smallclear specimens were used to study the properties of ... see more

Conventional hydraulic fracturing is not effective in target oil development zones with available wellbores located in the azimuth of the non-maximum horizontal in-situ stress. To some extent, we think that the radial hydraulic jet drilling has the functi... see more

Most city agglomerations of developing countries face water shortages and pollution due to population growth and industrial aggregation. To meet such water security challenges, policy makers need to evaluate water use efficiency at the regional or basin l... see more

In this paper, we measured the breakdown curves of a dc glow discharge with hollow cathode and flat electrodes. It is shown that at low gas pressure (p = 0.05 Torr), the left branches of the breakdown curves for the hollow cathode and the f... see more

Increasing the growth rate of teak trees is carried out to shorten the tree harvest rotation and reduce the deficit of teak timber supply, while maintaining the superiority of wood properties. The study was conducted to study the nature of five-year-old J... see more
