In the cruise, MR15-04 by R/V MIRAI, the samplings by the neuston net were performed in 23rd November to 14th December 2016 and three species of Halobates (H. germanus, H. micans, H. sp) were used for the temperature tolerance experiments after the collection. The neuston net was towed three times (3 × 15 min) on the starboard side of R/V MIRAI on the water surface with ship speed of 2 knot to water every 3 nights (19:00 - 20:00) at the fixed point in the south-western direction which was located at 50 km from the Sumatra island (4o03'S - 4o05'S, 101o53'E) in the Indonesia. Experiments on cool coma and heat coma were performed on the three species. Seconds for recovery from cool coma and heat coma were also examined on the Halobates in this study. Cool coma temperatures, gap temperature needed (temperature from the adapted temperature) for the cool coma and seconds for the recover from cool coma ranged 13.0oC to 25.0oC, 3.1oC to 16.1oC, 1 second to 4370 seconds, respectively. Heat coma temperature, gap temperature needed for the heat coma, seconds for the recover from heat coma ranged 29.4oC to 43.1oC, 1.9oC to 15.5oC, 2 seconds to 6420 seconds, respectively. The higher temperature of cool coma temperature during the last five days was shown when Madden-Julian Oscillation has passed over the ship, R/V MIRAI than the previous 10 days in the adults of H. germanus collected at the fixed place neat to Sumatra island (One way ANOVA: F-value = 2.314, df = 7, p = 0.028). Adults of un-described species, H. sp collected near to the Sumatra island, showed lower cool coma temperature [Mean ± SD: 15.51 ± 3.76 (9)] than those of H. germanus collected in the same place [16.96 ± 2.57 (191)]. This lower cool coma temperatures shown by this un-described species might be related to that this species should be a “shore” species inhabiting shore water in which many precipitation could cause the decreased surface temperature from 30oC - 31oC into about 25oC. Most of adults which suffere

Objectives: The objective of this study is clinical evaluation after introduction of stem cell supernatant Biocell Shot 65 by electroporation. Background: There is a clinical report of psoriasis treatment by umbilical cord blood-derived stem cells, in which there was a beneficial result. These clinical results are the result of cord blood-derived cell growth factors. The umbilical cord blood-derived stem cell culture supernatant contains a high amount of TGF-β, PDGA, etc., and promotes wound healing. In addition, we suppose that the supernatant has the esthetic effect of improving skin condition, thus, we planned to make a clinical evaluation. However, it is difficult to set judgement criteria, and human judgement tends to be subjective. Therefore, in this study, as a new clinical evaluator, we used an AI skin diagnostic device with learning function. Methods: Stem cell culture supernatant Biocell Shot 65 was used as an introduction solution. After it was applied to the full faces of four patients, electroporation with BeBe pinocchio DM-5 SUPER DX Plus promoted infiltration deep in the keratinized layer. The patients were all healthy women in their forties. This procedure was performed every two weeks for three months. Wrinkles, fine lines around eyes, stains, pores, and 4V, which is considered as one diagnostic criteria, were eva

Titanium based titanium dioxide （TiO2） nanotube arrays were prepared by electrochemical oxidation method, their microstructures were characterized, and the effects of sintering temperature and initial dye concentration and pH value on degradation performance of TiO2 nanotubc arrays wcrc investigated with methyl orange as a degradation object. The results showed that TiO2 nanotube arrays prepared by sintering at 500 ℃ exhibited good morphology and the highest photocata- lyric degradation efficiency; the degradation efficiency of the TiO2 nano material （500 ℃ ） to high concentration dye was higher than that to low concentration dye; the TiO2 nanotube array （500 ℃ ） exhibited higher degradation efficiency on dye solution at the pH of 3 than on that at the pH of 5.77 ; and the degradation efficien- cy of the TiO2 nanotube array （500 ℃） to 10 mg/L methyl orange solution （pH =3） reached 85.2%.

The whole field measurements of swirling flow in spin-up and spin-downprocesses via PIV are presented in the paper. Investigation of the flow patterns at H/R = 1. 50 wasexperimentally carried out for the first time in both processes. By means of symmetry analysis, itis found that the overall flow structure in the spin-up process still keep axi-symmetric to a greatextent, but deteriorated very fast in the spin-down process. The time to settle to the state of restin the spin-down process is found to be greatly shorter than the time to achieve the steady statein the spin-up process. Temporarily oscillatory vortex breakdown was discovered during the spin-upprocess, although no breakdown in the steady state at the same Reynolds number is found in preciousresearches.

This paper presents an approach to control rolling locomotion on the level ground with a biologically inspired hexapod robot. For controlling rolling locomotion, a controller which can compensate energy loss with rolling locomotion of the hexapod robot is designed based on its dynamic model. The dynamic model describes the rolling locomotion which is limited to planar one by an assumption that the hexapod robot does not fall down while rolling and influences due to collision and contact with the ground, and it is applied for computing the mechanical energy of the hexapod robot and a plant for a numerical simulation. The numerical simulation of the rolling locomotion on the level ground verifies the effectiveness of the proposed controller. The simulation results show that the hexapod robot can perform the rolling locomotion with the proposed controller. In conclusion, it is shown that the proposed control approach is effective in achieving the rolling locomotion on the level ground.

Bubble-type vortex breakdown of the swirling flow inside a closed cylindricalcontainer with a rotating upper endwall was experimentally investigated via LDV. 3D measurement ofthe steady bubble at H/R =1.5 was firstly carried out with very fine grid arrangement. Flow detailsinside the bubble and its Re -dependent structure were made clear. Abrupt waves of the azimuthalvelocity component were always found to be between the bottom stationary endwall and the upstreamstagnation point, which might be the reason of bubble formation. Variation of bubble structure andbubble center with the increasing Re gives the explanation for the disappearance of the breakdownregion.

Legged robots based on one degree-of-freedom reconfigurable planar leg mechanisms, that are capable of generating multiple useful gaits, are highly desired due to the possibility of handling environments and tasks of high complexity while maintaining simple control schemes. An essential consideration in these reconfigurable legged robots is to attain stability in motion, at rest as well as while transforming from one configuration to another with the minimum number of legs as long as the full range of their walking patterns, resulting from the different gait cycles of their legs, is achieved. To this end, in this paper, we present a method for the generation of input joint trajectories to properly synchronize the movement of quadruped robots with reconfigurable legs. The approach is exemplified in a four-legged robot with reconfigurable Jansen legs capable of generating up to six useful different gait cycles. The proposed technique is validated through simulated results that show the platform's stability across its six feasible walking patterns and during gait transition phases, thus considerably extending the capabilities of the non-reconfigurable design.
