APPLICATION OF BLENDED CEMENT IN SHOTCRETE TO

The application of blended cements in shotcrete is investigated to reduce the environmental burden. Reduction of the environmental burden and meeting the required properties of quick setting and strength development are achieved using blended cements with blast furnace slag and a powder accelerator with a main component of calcium sulfo-aluminate. The powder accelerator is hydro-reactive and promotes quick setting and strength development in shotcrete. The reduced environmental burden of shotcrete with blended cement and powder accelerator are calculated

Rare Case of a Giant Hamartomous Polyp of Brunner's Gland

During an investigation of the upper digestive tract of a 61-year-old female patient mainly complaining of hematemesis and melena, a peduculated polyp was discovered in the duodenum, and was surgically removed. Histologically, the polyp was recognized as a hamartomous polyp of Brunner's gland. Concerning the cases reported as so-called "Brunner's gland adenoma" it seems that there is a considerable difference in the histo­logical findings between Japanese cases and Western experiences, and this point is discussed in this paper, referring mainly to our case and other cases reported in Japan

After the accident of the Fukushima Daiichi nuclear power plant by the Great East Japan Earthquake on March 11, 2011, concern about radiation is increasing and monitoring of environmental radiation is performed even in Kagawa Prefecture. Then, we investigated for a short period of time for the purpose of creating the dose rate distribution map of Kagawa Prefecture while getting to know the dose rate of each municipality in Kagawa Prefecture in detail using a car-borne survey technique. As a result of measurement, the dose rates were low in the plain regions and those became high in the mountainous regions. Due to the average value of each municipality, the dose rates of municipalities in the southeastern prefecture, which contain Izumi Group and mountainous region affluent in granite, were high. The average dose rates of all municipalities in Kagawa Prefecture were obtained from this investigation, and the dose rate distribution map was created. From the tendency of the dose rate distribution in Kagawa, it has confirmed that a dose rate changed with geographical feature or geology

A Car-borne Survey of Environmental Radiation in Shikoku, Japan

We investigated the environmental radiation in Shikoku area using a car-borne survey and obtained the change of dose rate by continuous survey. Dose rartes in Ozu city and its surrounding area, Ehime prefecture were the lowest in other areas of Shikoku. Dose rates obviously changed on the north side of it’s low dose rates area but gradually changed on the south side. Dose rates in Ashizuri-misaki, Kochi prefecture were the highest in Shikoku and changed in accordance with the boundary of geological structure. Dose rate on the survey route, from Imabari city in Ehime prefecture to Shimanto city in Kochi prefecture, was the lowest at the surrounding area of the prefectural boundary. This lowest dose rate was considered to be caused by geological structure. The influence of altitued on dose rates was not observed in this survey route.The average dose rates of environmental radiation in Ehime prefecture and Kochi prefecture were almost the same and the lowest in Shikoku. Tokushima prefecture was the highest in the average dose rates of environmental radiation of other prefectures in Shikoku

Palaeoproteomic investigation of an ancient human skeleton with abnormal deposition of dental calculus

Detailed investigation of extremely severe pathological conditions in ancient human skeletons is important as it could shed light on the breadth of potential interactions between humans and disease etiologies in the past. Here, we applied palaeoproteomics to investigate an ancient human skeletal individual with severe oral pathology, focusing our research on bacterial pathogenic factors and host defense response. This female skeleton, from the Okhotsk period (i.e., fifth to thirteenth century) of Northern Japan, poses relevant amounts of abnormal dental calculus deposition and exhibits oral dysfunction due to severe periodontal disease. A shotgun mass-spectrometry analysis identified 81 human proteins and 15 bacterial proteins from the calculus of the subject. We identified two pathogenic or bioinvasive proteins originating from two of the three "red complex" bacteria, the core species associated with severe periodontal disease in modern humans, as well as two additional bioinvasive proteins of periodontal-associated bacteria. Moreover, we discovered defense response system-associated human proteins, although their proportion was mostly similar to those reported in ancient and modern human individuals with lower calculus deposition. These results suggest that the bacterial etiology was similar and the host defense response was not necessarily more intense in ancient individuals with significant amounts of abnormal dental calculus deposition

BabyTigers 2001: Osaka Legged Robot Team

We have developed all kinds of motions such as walking, standing-up, and kicking towards Seattle. From a human designer’s point of view, it is easier to write strategies based on the geometric, global position data but seems less attractive. Then, we are attacking learning issues such as action selection [1] [2], observatio
