The Haramachi Fault segment in the northeastern part of Honshu Island, Japan, has mainly sinistral fault movements with minor reverse component within Futaba Zone Japan arc. 2011 Mw 9.0 earthquake occurred off Pacific coast Tohoku which caused large crustal deformations. Despite being closest active to epicenter, very limited investigation been conducted on Zone. Previous studies used smaller s...
Aiming to lack the function of soil covering in developed orchard straw mulching machine (OSM), a kind bilateral counter-throwing soil-covering device was eliminate fire risk caused by layer. The suspended at rear OSM. Its core component pair throwing wheels installed on both sides frame. Hydraulic motors drove take on-site and cover adjustment range space between 1.4-2.1 m. Based analysis quan...
We measured the change in aboveand below-ground carbon and nutrient pools 11 years after the harvesting and site preparation of a histic-mineral soil wetland forest in the Upper Peninsula of Michigan. The original stand of black spruce (Picea mariana), jack pine (Pinus banksiana) and tamarack (Larix laricina) was whole-tree harvested, and three post-harvest treatments (disk trenching, bedding, ...
Geological identification of tsunami deposits is important for tsunami hazard studies, especially in areas where the historical data set is limited or absent. Evidence left by historical tsunamis in the coastal sedimentary record of the Gulf of Corinth was investigated by trenching and coring in Kirra on the north coast and Aliki on the south coast. The Gulf of Corinth has a documented tsunami ...
The automation of mobile working equipment used in farming, forestry and the construction industry has great market potential. Tasks of a highly complex nature could be executed without intervention of the operator. Despite the potential significance of this topic, only very few results of international research projects in robotics have heretofore been applied in the serial production of comme...

The paper presents a multi-method characterisation of the Roman quarry middle Lower Jurassic (Pliensbachian) limestone situated in village Podpeč, south Ljubljana, and examples placement stone products made from micritic, fine-grained, oolithic facies into known extent quarry. 23 m rock succession ancient was exposed at northern tip St. Ana Hill by archaeological trenching. Petrological, microp...
In the northern part of Sumatra Island, Indonesia, Great Sumatran Fault, which can cause an earthquake, was divided into two segments: Aceh and Seulimeum. An effort to reduce risk is mapping fault area, especially in region that does not clearly show sign on surface, e.g., Lamtamot Indonesia. Electrical resistivity widely used study shallow structures, but method requires more time when applied...
