In the present work, the effects of intercritical annealing parameters on the microstructure and cold rollability (deformation rate and ratio) of “3rd Generation Advanced High Strength Steels (AHSS)” were studied. Hence, this paper discusses the formation of microstructures with different volume fractions of ferrite, martensite, bainite and retained austenite (RA). Two novel microstructures have been created, based on two levels of manganese (Mn): (i) ferrite plus martensite nucleated in austenite microstructure (FMNA structures), using Mn levels of 5 to 7 wt% and (ii) ferrite plus retained austenite duplex structure (FADP steels) for a Mn level of 10 wt%. In general, the ductility is a function of the amount of retained austenite and the strength is highly dependent on the martensite level.

Noise reduction effect using decoupling capacitor with series resistor was studied. It is well known that the decoupling capacitor is a familiar noise reduction technique on a printed circuit, and its effect is limited at high frequency by some parasitic inductances such as lead, trace and so on. Some capacitors are often connected in parallel for widening its band, but its impedance grows up highly at parallel resonance frequency. In this paper, the effect of the suppression of parallel resonance by decoupling capacitor with resistor is described and the relation between band width and device parameters is shown. The reducion effect is measured and simulated about transmission characteristic and near magnetic field.

A tsunami was generated by the 1994 Hokkaido Toho-Oki earthquake and was observed at tidal stations on the Pacific coast of the Japanese Islands. It was observed also at several tidal stations on Hokkaido coast of the Okhotsk Sea, where the arrival of the initial wave was recorded earlier than the expected time: for example, the initial motion of the tsunami was recorded at Utoro 17 minutes after the mainshock, while that the theoretically expected tsunami arrival time from the source in the south sea region of Shikotan Island is 80 minutes after it. We tried to estimate the location of the source of the early coming waves by drawing the inverse refraction diagram from each station. We suggest two probable locations of the source; one is the area 80 kilometers north of Abashiri, and the other is the area 40 kilometers north of the tip of Shiretoko Peninsula. The seismic activity at both of those areas is poor. So, we cannot judge that the early coming waves were generated by some another events. Both of those areas are situated in the continental slope regions and with steep slopes. We suppose that a land slide at either of those areas caused the early coming waves.

In the present research, psychological states of elderly people in the process of raising plants were analyzed by means of brain waves and semantic differential technique.The experiment carried out from October 2004 to January 2005. Subjects were ten elderly individuals (mean age, 70.5 years) and ten young individuals (mean age, 21.0 years). Each subject raised three kinds of plants (Pachira glabra Pasq., Myrtillocactus geometrizans Console and Cyclamen persicum Mill. cvs.) for ten weeks in his or her house. At the zeroth, second, sixth and tenth week of the experiment, the subjects brought their plants to a laboratory at Ehime University. In the laboratory, the psychological states of the subjects in seeing their plants in front of them were evaluated by brain wave and semantic differential technique. The Cyclamen persicum Mill. cvs. of most subjects lost its flowers and leaves and declined in appearance at approximately the sixth week.The ratio of alpha wave to beta wave calculated an index of the degree of calmness of psychological state. As for the elderly subjects, the differences of the ratios of alpha wave to beta wave between the evaluated plants became smaller according to the raising weeks. The influence of the deterioration of the Cyclamen persicum Mill. cvs. on the psychological states of the elderly subjects was not observed. The semantic differential data were almost the same the brain waves data. These results indicated that elderly people's psychological states became stable and calm in the process of raising plants.

Concentration of 137Cs, 134Cs and potassium were measured in several higher fungi and in substrates, soils, woods and litters in some Kanto and the Koshin districts, Japan, following the Chernobyl accident during October to November 1989. 137Cs concentrations in fungi were in the range of 0.7-101 Bq kg-1⋅fresh. Maximum 137Cs level in them was observed in Boletopsis leucomelas (Pers.: Fr.) Fayod. Significantly higher levels of concentration ratios of 137Cs in fungi to substrates (e.g.; 137Cs concentration · fresh in fungus/137Cs concentration · dry in soil), 10-1 to 10×10-1, were found nearly 10 to 1000 times as much as leaf vegetables, root crops and potatoes to substrates. It was confirmed that levels of concentration ratios of potassium were similar to those of 137Cs. In all fungi, 134Cs which released from the Chernobyl accident and is not present in nuclear weapons fallout was not detected.

In this paper, we analyze the key factors underlying the implementation, evaluation, and optimization of image processing and computer vision algorithms on embedded GPU using OpenGL ES 2.0 shader model. First, we present the characteristics of the embedded GPU and its inherent advantage when compared to embedded CPU. Additionally, we propose techniques to achieve increased performance with optimized shader design. To show the effectiveness of the proposed techniques, we employ cartoon-style non-photorealistic rendering (NPR), speeded-up robust feature (SURF) detection, and stereo matching as our example algorithms. Performance is evaluated in terms of the execution time and speed-up achieved in comparison with the implementation on embedded CPU.

Simulation of polymerization-induced phase separation of a polymer gel from a multifunctional monomer was carried out using the phase field method. To describe the driving force for phase separation, the interfacial energy between the polymeric phase and the aqueous phase was assumed to depend positively on the degree of polymerization, while the thickness of the interface at equilibrium and the mobility were assumed to depend negatively on it. The mobility was also assumed to depend negatively on the volume fraction of the polymer. A sigmoidal function was introduced to describe the nonlinear dependence of the mobility on the volume fraction. The wavelength of phase separation became finer as the polymerization rate increased when the rate of the reaction had a time scale similar to that of diffusion. When a nonreactive polymer coexists in the phase separation, the wavelength of phase separation shrinks because of suppression of diffusion caused by the coexisting polymer. These results qualitatively agreed with the experimental results for macroporous silica prepared via polymerization-induced phase separation.

For the purpose of improving the taste, chicken livers were preserved in raw rice miso, raw soybean miso, cooked rice miso or cooked soybean miso at 5°C for 168 hrs. During the preservation, the properties of chicken livers were examined. The results are as follows.(1) As to the varieties of rice miso, the chicken liver preserved in Shinsyu rice miso contained sligtly more protein, amino-nitrogen and sodium chloride and showed a higher hardness and achieved better evaluation for taste, as compared with that preserved in Saikyou rice miso, though the former was somewhat inferior in color to the latter.(2) The optimal preservation period of the chicken liver in miso was 48 his, regardless of the varieties of miso.(3) The chicken liver preserved in raw soybean miso contained more protein and amino acids, and higher protease activity at pH 5.7, and was superior in color, taste and preservability, as compared with those preserved in the other miso.

As one of the series of studies on radiation leukemogenesis, changes in the peripheral blood picture occurring with lapse of time were pursued with the Cb, D103, StA, and Zb strains of mice (30-50 days old) after a single whole body X-irradiation of 350 r. The results are summarized as follows.1. Both erythrocyte counts and hemoglobin contents showed the minimum values 2 weeks after the irradiation, and after recovering once they tended to decrease again. Reticulocytes decreased to about 2-4‰ immediately after the irradiation but by the second week they increased to about twice the number in normal condition, and thereafter they returned to the normal count. This change was most marked in the D103 strain, but ultimately the changes in the erythrocyte series presented similar curves in all the four strains mentioned above, and these changes did not differ from those observed in RF strain.2. The number of leukocytes decressed rapidly to as low as 2, 000 immediately after the X-irradiation. The susceptibility to X-ray irradiation was higher in the leukocyte series than in the erythrocyte series.3. Lymphopoiesis was more sensitive to X-irradiation than myelogenous hematopoiesis, and the decrease of lymphocytes was greater than that of neutrophils, showing a relative neutrophilia for several weeks after the irradiation.4. After once recovering, the leukocyte counts in the Cb, D103, StA, and Zb strains of mice all did not show such a transient decrease as observed in the preleukemic stage of RF strain about 13 weeks after the irradiation. In addition, lymphocytic leukemia did not develop.5, In the Cb, D103, StA, and Zb strains irradiated with X-ray there could be recognized no severe eosinophilia such as observed in the RF strain that received X-irradiation.From these findings it has been confirmed that there can be recognized no marked differences in the peripheral blood picture immediately after a single whole body X-irradiation of 350 r between the RF strain of mice that develop leukemia by X-ray, and the Cb, D103, StA. and Zb strains that do not develop leukemia by X-irradiation, but in the observations conducted thereafter along with lapse of time there can be seen several distinct differences in the changes of the leukocyte series between them.

麻酔中の輸液は血管内輸液,間質への輸液,細胞内への輸液の3本立てで考える.細胞外液製剤はブドウ糖以外の糖を浸透圧調整のため含んでいる製剤が容量効果と利尿効果をもっているので使いやすい.ヒドロキシエチルスターチ(HES)は血管内輸液として適切である.膠質浸透圧は測定膜,内皮細胞臓器特異性,病態を考慮する必要がある.HESには抗炎症作用があり,末梢循環を維持することができる.6% HES70は腎や止血凝固への影響は最も少ない.輸液のモニターとして尿量が臨床的である.圧モニターとしてのCVPより経食道心エコー下の容量負荷を重視した考え方がある.混合静脈血酸素飽和度や乳酸値は輸液を含めた周術期管理の総合的なモニターとして重要である.

Construction is one of the world’s biggest industry that includes jobs as diverse as building, civil engineering, demolition, renovation, repair and maintenance. Construction workers are exposed to a wide variety of hazards. This study analyzes 1,117 expert witness reports which were submitted to criminal and labour courts. These reports are from all regions of the country and cover the period 1972–2008. Accidents were classified by the consequence of the incident, time and main causes of the accident, construction type, occupation of the victim, activity at time of the accident and party responsible for the accident. Falls (54.1%), struck by thrown/falling object (12.9%), structural collapses (9.9%) and electrocutions (7.5%) rank first four places. The accidents were most likely between the hours 15.00 and 17.00 (22.6%), 10:00–12:00 (18.7) and just after the lunchtime (9.9%). Additionally, the most common accidents were further divided into sub-types. Expert-witness assessments were used to identify the parties at fault and what acts of negligence typically lead to accidents. Nearly two thirds of the faulty and negligent acts are carried out by the employers and employees are responsible for almost one third of all cases.

Although many studies have examined eye movements in reading, it is unclear what factors separate fast readers from slow readers. Some studies suggest that effective visual field size should be a dominant factor. However, a direct link between reading speed and effective visual field is under controversial. To clarify this issue, we investigated eye movements in reading in conjunction with speed reading training. Four participants (approx. 600 letters per minute in Japanese) improved thier reading speed through training for half an hour per day for 30 days. Reading performance of Japanese editorial articles was recorded every five days of training by the gaze-contingent window method. In three participants, effective visual field size did not increase in the same manner as reading speed which increased up to 1000 lpm. Instead, we found that in those three participants mean saccadic length became longer due to the reduction of short and unsystematic saccades. On the contrary, one participant showed high correlation between effective visual field and reading speed. Our results suggest that not only the size of the effective visual field but also efficiency of comprehension at a single gaze may be important factors for reading speed. The qualitative discrepancy among individuals suggests the existence of multiple strategies for fast reading.

GM2 gangliosidosis variant 0 (Sandhoff disease, SD) is a fatal, progressive neurodegenerative lysosomal storage disease caused by mutations of the HEXB gene. In canine SD, a pathogenic mutation (c.283delG) of the canine HEXB gene has been identified in toy poodles. In the present study, a TaqMan probe-based real-time PCR genotyping assay was developed and evaluated for rapid and large-scale genotyping and screening for this mutation. Furthermore, a genotyping survey was carried out in a population of toy poodles in Japan to determine the current mutant allele frequency. The real-time PCR assay clearly showed all genotypes of canine SD. The assay was suitable for large-scale survey as well as diagnosis, because of its high throughput and rapidity. The genotyping survey demonstrated a carrier frequency of 0.2%, suggesting that the current mutant allele frequency is low in Japan. However, there may be population stratification in different places, because of the founder effect by some carriers. Therefore, this new assay will be useful for the prevention and control of SD in toy poodles.

We investigated biodegradability and new bone formation after implantation of tetrapod-shaped granular artificial bone (Tetrabone®) or β-tricalcium phosphate granules (β-TCP) in experimental critical-size defects in dogs, which were created through medial and lateral femoral condyles. The defect was packed with Tetrabone® (Tetrabone group) or β-TCP (β-TCP group) or received no implant (control group). Computed tomography (CT) was performed at 0, 4 and 8 weeks after implantation. Micro-CT and histological analysis were conducted to measure the non-osseous tissue rate and the area and distribution of new bone tissue in the defect at 8 weeks after implantation. On CT, β-TCP was gradually resorbed, while Tetrabone® showed minimal resorption at 8 weeks after implantation. On micro-CT, non-osseous tissue rate of the control group was significantly higher compared with the β-TCP and Tetrabone groups (P<0.01), and that of the β-TCP group was significantly higher compared with the Tetrabone group (P<0.05). On histology, area of new bone tissue of the β-TCP group was significantly greater than those of the Tetrabone and control groups (P<0.05), and new bone distribution of the Tetrabone group was significantly greater than those of the β-TCP and control groups (P<0.05). These results indicate differences in biodegradability and connectivity of intergranule pore structure between study samples. In conclusion, Tetrabone® may be superior for the repair of large bone defects in dogs.

広島県沿岸部において1988年11月から1990年7月にかけて,のべ406個体(うち,巣内雛に117個体)のエナガに標識してつがい形成および繁殖生態について調査した.1)調査地は森林•宅地•農耕地などが複雑に入りくんだ林縁部で,11月から翌年の2月にかけてみられる冬季群のメンバーは安定しており,それらの行動圏も決まっていた.2)成鳥が繁殖期の前に移動し,群れ間でのつがい形成が普通に起こることが明らかになった.3)冬季群は繁殖期に解消され,繁殖期には群れそのものが存在しないことが明らかになった.4)繁殖終了後,冬季群形成前に多くの個体が消失する一方,調査地外から移入してくる個体がいることが明らかになった.5)冬季群のメンバーは,前年と同じ群れに残っていた成鳥,調査地内で出生した幼鳥からなる標識個体,調査地外から移入してきた幼鳥を含む未標識個体で形成されたが,移入個体が半数近くを占あたので,林縁部のエナガの冬季群が血縁集団である可能性はうすいと考えられる.6)ヒナが孵化した巣では高い割合でヘルパーが現れたが,中でもオス親がヒナの孵化以前に消失した巣にヘルパーが現れる率は非常に高かった.7)履歴の確認できたヘルパーはいずれも繁殖に失敗し配偶者が消失したオスであった.
