Purpose: To examine the characteristics of ambulatory blood pressure (ABP) including blood pressure variability (BPV) and its association with albuminuria in type 1 diabetic (T1D) children and to identify potential predictors of high-normal albuminuria and microalbuminuria. Methods: ABP monitoring was performed in 201 T1D children and adolescents (mean age, 14.7±3.8 years) with T1D duration over 1 year. The level of albuminuria was assessed as the albumin/creatinine ratio (ACR) and patients were further classified as low-normal, high-normal or microalbuminuria. Results: Fifteen T1D children (7.5%) were hypertensive using office blood pressure (BP) and 10 (5%) according to ABP. T1D subjects had elevated 24-hour systolic BP (SBP) and diastolic BP (DBP) (+0.2 and + 0.3 standard deviation score [SDS]) and nighttime SBP and DBP (+0.6 and +0.8 SDS) compared to reference values. Patients with microalbuminuria had significantly higher 24-hour, daytime and nighttime DBP compared to normoalbuminuric subjects. There was a high percentage of nondippers (74.1%). Nighttime diastolic BPV was significantly higher in subjects with high-normal compared to low-normal albuminuria (P=0.01). A weak correlation was found between ACR and daytime DBP SDS (r=0.29, P<0.001 and nighttime DBP SDS (r=0.21, P=0.003). Age and nighttime diastolic BPV were predictors of high-normal albuminuria while nighttime DBP was a strong predictor for microalbuminuria. Conclusion: T1D children have impaired BP regulation although most of them do not fulfill the criteria for sustained hypertension. There is an association between diastolic ABP and diastolic BPV with rising levels of albuminuria pointing to a clear connection between BP and incipient diabetic nephropathy.

In Japan, Quarter-million crossing collisions at intersections accounted for one-fourth of the total accidents in 2005. Three-fourths of collisions took place at urban intersections, more than half of them occurred at uncontrolled intersections. Risks of crossing collisions depend on the quality of visual environment at intersection. This study aimed to assess the legibility and effectiveness of 23 traffic convex mirrors installed at 10 urban intersections, after the road management authority inspected and repaired. The legibility of mirror was assessed by means of the photographs of each mirror taken from the drivers’ viewpoint at a legal stop line, entering from the lower priority direction. “Three ergonomics requirements” suggested by the authors were used as the criteria of legibility assessment; (1) Position of road lane, (2) Blind area and (3) Road surface markings. Combining these 3 criteria, the comprehensive assessment of mirror was indicated in 2-grade scale, such as “Good” or “Poor”, namely so dangerous to be improved. A field assessment revealed that 11 among 23 mirrors were still improperly installed. However, simulation analysis showed that 7 among 11 poor mirrors could be improved by adjusting the angle of mirror plate or displacing mirror plate/poles. In conclusion, the present official guideline in regard with installing mirror should be revised to add newly “three ergonomics requirements” for preventive safety. Application of these new guidelines in practice, a typical low-cost and low technology-oriented improvement to reduce crossing collisions, was highly recommended.

Fatty acid-amino acid conjugates (FACs), first identified from beet armyworm Spodoptera exigua larvae (Alborn et al., 1997), have been found in noctuid as well as sphingid caterpillar oral secretions and especially volicitin [N-(17-hydroxylinolenoyl)- L-glutamine, 17OH-volicitn] and its biochemical precursor, N-linolenoyl- L-glutamine, are known elicitors of induced volatile emissions in corn plants. We conducted FAC screening of 29 lepidopteran species and found FACs in 19 of these species (Yoshinaga & Mori et al., 2010). Thus, FACs are quite commonly synthesized through a broad range of lepidopteran caterpillars. From an evolutionary perspective, it is presumed that volicitin and the other FACs, although consequently unfavorable to the insect in the plant-herbivore interactions, are produced because they are essential part of the primary metabolism of the insects. In this context, we suggested that FACs in Spodoptera litura play an active role in nitrogen assimilation by regulating the amount of glutamine in the larval midgut (Yoshinaga & Mori et al., 2008). The benefits of the physiological function of FACs for the herbivores need to outweigh the costs caused by induction of plant defense
Effect of a dynamic absorber on friction-induced vibration of a rectangular plate

When a plate-like object is rubbed by rubber, friction-induced vibration is generated. To reduce the friction-induced vibration, we experimentally investigate the characteristics of the vibration of a rectangular glass plate. The results show that the frequency of the frictioninduced vibration is almost the same as the natural frequency of a glass plate. The vibration is generated when the natural frequency of a rubbing system is close to that of a glass plate. We then examine the effect of a dynamic absorber mounted on the glass plate. The results demonstrate that the damping of a dynamic absorber is effective for suppressing the friction-induced vibration. Numerical simulation is also performed using a simplified analytical model. The calculated results agree qualitatively with the experimental ones.
Behaviour of laminated elastomeric bearings
Mori, A.,Moss, P.J.,Carr, A.J.,Cooke, N. Techno-Press 1997 Structural Engineering and Mechanics, An Int'l Jou Vol.5 No.4
Experimental work undertaken to investigate the behaviour of laminated elastomeric bridge bearings under compression and a combination of compression and shear or rotation has been reported on elsewhere. However, it is difficult to determine the state of stress within the bearings in terms of the applied forces or the interaction between the steel shims and the rubber layers in the bearings. In order to supply some of the missing information about the stress-strain state within the bearings, an analytical study using the finite element method was carried out. The available experimental results were used to validate the model after which the analyses were used to provide further information about the state of stress within the bearing.
Advanced surface processing of NLO borate crystals for UV generation

Recent advances in NLO Borate Crystals for UV Generation are reviewed with the particular emphasis on the technique to improve the life time of UV optics. The laser-damage resistance of CLBO and fused silica surfaces was successfully improved after removing polishing compound by ion beam etching. The polishing compound embedded in the CLBO and fused silica surfaces were to a depth of less than 100nm. We were able to remove polishing compound without degrading the surface condition when the applied ion beam voltage was less than 200 V. The laser-induced surface damage threshold of CLBO was improved up to 15J/$\textrm{cm}^2$(wavelength: 355 nm, pulse width: 0.85 ns)as compared with that of the as-polished surface (11 J/$\textrm{cm}^2$). The laser-induced surface damage of fused silica also increased from 7.5J/$\textrm{cm}^2$ to 15J/$\textrm{cm}^2$. For the irradiation of a 266 nm high-intensity and high-repetition laser light, the surface lifetime of CLBO and fused silica could be more doubled compared with that of the as-polished surface.
