A study measured the drill resistances of larch and Scotch pine by a drill resistance technique and compared the densities of the same specimens measured with a traditional volumetric method. The drill resistance technique was found to be a good measure of the density profile of wood to reflect tree rings and defects (knots, decay and hollows). The drill resistance technique as applied to pines uses a linear relationship between the wood density and the average drill resistance. This technique has the applicability and possibility as a possible method for the density measurement and the defects detection. The technique is rapid, inexpensive, safe, portable and has the potential to be adopted as an on-line density profile method.

This paper discusses the advantages of frequency modulated transmission of information in plants, and how this philosophy is adapted in practice in the form of two instruments for on-line measurement of liquid and gas densities. The importance of measuring density is well appreciated for on-line blending and various forms of quality control applications, but special attention is drawn to its necessity in gas flow metering.

Tampusu Mountain (± 1500 m above sea level) is located between two famous geological tourism areas in North Sulawesi, namely Lake Linow and Lake Tondano. The position of Mount Tampusu, as well as the presence of geothermal manifestations in the surrounding area is interesting to study its geological aspects both on the surface and below the surface. This study aims to determine the existence of surface geological structures based on line density, and also to determine the presence and direction of subsurface geological structures based on gravity anomaly data in Tampusu Volcanic area. The fault and fracture density method is used to map the surface geological structure, while the gravity method is used to obtain information about the geological structure of the Tampusu volcanic area between the crater of Lake Linow and the Lake Tondano caldera. The existence of a fault is known to be west of the Lake Tondano caldera which is an extension from east to southeast of the Linow Lake crater. There is a relationship between the distribution map of the bouguer anomaly value and the map of lineament density along the Lake Linow crater to Lake Tondano caldera.
