Historical information related to tsunamis generated in the Nankai Trough was compiled to examine their frequency and associated destruction. Types of damage in a wide area throughout western Japan from Boso to Kyushu, Susaki, Kochi, and Osaka were selected to elucidate tsunami behavior and damage to areas where multiple damage to facilities was reported, such as that to floated ships, bridge destruction, and road blockage by strong current and floating materials such as destroyed house and ships. After reviewing the tsunami physics and damage from recent events including that related to 2004 Sumatra, suggestions are offered to mitigate future disasters.

The Impact

This paper estimates the impact of the tsunami caused by the Great East Japan earthquake on land appraisals of various locations outside of directly damaged areas. The focus is on locations that are expected to be extensively damaged by a tsunami if the Nankai Trough earthquake occurs. We use the DID and DDD approaches and show that locations with low elevation and close to the sea experienced decreases in appraised land prices compared to locations with high elevation and far from the sea. Especially, locations with less than 3.6m elevation and within 1.46km of the coastline experienced significant decreases in appraised land prices. This result implies that people have changed their location preferences regarding elevation and distance from the sea.

Integrate Research

To integrate research results of this project and apply to practical disaster mitigation measures, we arrange and construct working groups in Nagoya city, Osaka city and Kochi city. In these cities, severe damages of next megathrust earthquakes around the Nankai trough are estimated, therefore, we will discuss with administrative organs, public corporations of life lines and researchers etc. in each working group. In discussions of working group, we introduce advanced researches to understand the present and future expected researches of the Nankai trough in each other. Furthermore, we will extract characteristic issues and estimated damages of strong motions, long period motions and tsunamis based on the future scenarios of next meagthrust earthquakes in each working group. And fruits of working group discussions will contribute to constructions of new disaster mitigation measures in administrative organs, public corporations of life lines etc.

The Individual

An efficient, robust, and widely-applicable technique is presented for computational synthesis of high-resolution, wide-area images of a specimen from a series of overlapping partial views. This technique can also be used to combine the results of various forms of image analysis, such as segmentation, automated cell counting, deblurring, and neuron tracing, to generate representations that are equivalent to processing the large wide-area image, rather than the individual partial views. This can be a first step towards quantitation of the higher-level tissue architecture. The computational approach overcomes mechanical limitations, such as hysterisis and backlash, of microscope stages. It also automates a procedure that is currently done manually. One application is the high-resolution visualization and/or quantitation of large batches of specimens that are much wider than the field of view of the microscope.The automated montage synthesis begins by computing a concise set of landmark points for each partial view. The type of landmarks used can vary greatly depending on the images of interest. In many cases, image analysis performed on each data set can provide useful landmarks. Even when no such “natural” landmarks are available, image processing can often provide useful landmarks.

On convenient use of nanoprobe and scanning without a stem unit in an EM-420

Objective System

One of the strengths of the Philips EM-400 series of TEMs is their ability to operate under two distinct optical configurations: “microprobe”, the normal TEM operating condition which allows wide area illumination, and “nanoprobe”, which gives very small probes with high angular convergence for STEM imaging, microchemical and microstructural analyses. This change is accomplished by effectively turning off the twin lens located in the upper pole piece which changes the illumination from a telefocus system to a condenser-objective system. The deflection and tilt controls and alignments are designed for microprobe use and do not function properly when in nanoprobe. For instance, in nanoprobe the deflection control gives a mix of deflection and tilt; as does the tilt control.

This paper investigates costs and benefits associated with low-carbon economic development pathways realization to the mid XXI century. 30 scenarios covering practically all “visions of the future” were developed by several research groups based on scenario assumptions agreed upon in advance. It is shown that with a very high probability Russian energy-related GHG emissions will reach the peak before 2050, which will be at least 11% below the 1990 emission level. The height of the peak depends on portfolio of GHG emissions mitigation measures. Efforts to keep 2050 GHG emissions 25-30% below the 1990 level bring no GDP losses. GDP impact of deep GHG emission reduction - by 50% of the 1990 level - varies from plus 4% to minus 9%. Finally, very deep GHG emission reduction - by 80% - may bring GDP losses of over 10%.
