Coal, a relatively low-cost fuel that produces significant amounts of pollutants, supplies 18,7% of the Korean economy's energy needs. The total amount of coal consumend in 1995 was 43,6 Million tons, only 5,5 million tons are domestic anthracite;the rest is imported bituminous coal. The three major industrial sectors that utilize imported coal are …
In the 1960s 'and early 1970s the growth in world seaborne coal trade mainly reflected the increasing • demand for steel. Following the oil shocks of the 970s, the further strong growth in world coal trade been driven primarily by the rapid growth in cctricity generating capacity. Consequently, wh…

The relevant characteristic of the evolution of the Pacific continental margin of South America during the Mesozoic-Early Cenozoic has been tectonic segmentation. This has controlled succesive episodes of sedimentary accumula, Ition, extrusive and intrusive magmatism and deformation that ocurred at conververgent plate edges. …
Natural disasters are the, most serious potential threats to human being and their environments. Japan and Indonesia have the same type of natural hazards because of their similarity in tectonic setting. This was a major factor motivating the establishment of cooperative programs between Japan and Indonesia to understand the natural phenomena and th…
The Emperor vein system lies on the eastern margin of the Tavua volcanic structure. This is of Miocene age and occurs in basalts(the Mba Volcanics) probably underlain at about 2 km by calcite-rich sediments (the Vatukoro Formation). The lodes are generally flatmakes, or steep fault fillings, or complex shatter zones, and consist of quartz and altere…
An aapa mire was investigated peat geologically. Based on about 1500 volumentric peat samples, the depth, peat types, degree of decomposition (V. Post's methods), bulk density, water content and shear strength were examined along an 800 m transcet. The calorific value was determined from 58 respresentative peat samples from the same transect, as wel…
Historrical review of developments in peat production and processing with particullar reference to the advances borrowed from annd contributed to other industries. In today's peat technology there is virtually nothing new, most approhes have been tried before. Those that succeeded became standard practice; those that failed are too often forgotten. …
Above--ground blomass and primary production values for 40 sites representing 22 virgin mire types which occur in the southern boreal vegetation zone in finland are presenterd. Eight ameliorated sites are included in the material. The biomass ranges between 360 - 20 270 g/m2 and is strongly correlated with stem volume on forested sites. Total annua…
Marine technology is a complex science and Indonesia, needs a realistic strategy for the implementation of the relevant technology. The strategy should be evolutionary and should coincide with a national marine program, and with current prevailing domestic and international conditions. There is no doubt that present day practitioners will influence …
