The actuation performance of plasticized poly(vinyl chloride) (PVC) gel actuators in an electric field depends on their chemical composition and electrical mechanical properties. influence plasticizer (dibutyl adipate) content electromechanical behavior PVC gels was investigated by impedance spectroscopy space charge measurement. By plasticizing the PVC, dielectric constant density were drastically increased at 1:2 w/w ratio to plasticizer. To apply results obtained from measurement,...
As an electrode for a bending-electrostrictive polyurethane actuator, we prepared wrinkled polypyrrole electrode, expecting the following two effects because could easily elongate by smoothing wrinkles: (1) conductivity of would not decrease with field-induced surface elongation and (2) constrain actuation. The was through in situ deposition onto elastomer film that being uniaxially drawn. After deposition, released from drawing to make wrinkle. did at rates less than 40%. bending actuation...
The epidermal growth factor receptor (EGFR) level in 56 esophageal cancer tissues was measured by 125I-EGF binding assay to elucidate its role tumor progression. survival rate of patients with high EGFR (more than 50 fmol/mg protein) significantly lower that low (less protein, P less 0.01), although a correlation between and the pathologic findings not observed. expression EGF examined immunohistochemically using anti-EGF monoclonal antibody 100 tissues; EGF-positive cells were detected...
Autonomously oscillating soft actuators have been successfully obtained by assembling pre-existing microgel particles. The amplitude of the actuator's oscillation could be controlled selecting types oscillations constituent microelements, i.e., swelling–deswelling or cooperative dispersing–flocculating motion microgels. new prepared this fabrication process make suitable for practical use in microfluidic devices such as self-beating micropumps.
A PVC gel pupil that can elongate and change its curvature in response to an applied voltage of 400 V, with a deformation time about 6 s, is demosntrated. The displacement the radial direction was 470 μm, which corresponded approximately 100% thickness pupil, leak current at nanoampere level.
The aim of the present study was to investigate age-specific prognostic factors in patients who underwent gastrectomy for gastric cancer.The medical records 366 with cancer surgical resection at our hospital between January 2007 and December 2014 were retrospectively reviewed. Of patients, 117 aged 75 years or older 249 74 younger. All that identified as significant using univariate analysis included multivariate analysis.The median follow-up duration 52.9 months (range, 1.0-117.5 months)....
In order to examine the relationship between occlusal support and head posture, electromyographic (EMG) activities of jaw closing muscles sternocleidomastoid muscle during voluntary maximal clenching (VMC) under several conditions in eight healthy dentates were recorded analysed. The posture was also simultaneously by electromagnetic, 6-degree-of-freedom tracking instrument (POLHMUS Co. 3 SPACE-WIN*). VMC with lateral imbalance support, EMG activity on side greater than those non-occlusal...
Abstract A gel of poly(vinyl alcohol) highly swollen with dimethyl sulfoxide was demonstrated to actuate at a much faster rate (more than 1000 times) those reported on conventional actuators in air and flap wing 12.5 cm 2 Hz span 10 by periodically applying electric field. The action (8% length) induced the field reached several hundreds times larger ferroelectric solid materials. electrostrictive was, thus, found be promising candidate material as novel type actuator or artificial muscle...
Abstract Hydrogel prepared by repetitive freezing and thawing of poly(vinyl alcohol) aqueous solution was chemically crosslinked with glutaraldehyde. The hydrogel hardly changed its physical appearance, showed good elasticity strength as original gel. However, after treating in boiling water, it swelled a little, depending on the condition chemical treatment. melted gel thus obtained shape memorizing property, that is, could firmly hold nearly 200% strain, keeping high elasticity. strain be...
summary Successful prosthodontic treatments for a patient with removable partial dentures including maxillofacial prostheses hopefully brings about psychological wellbeing as well improved health. The purpose of this study was to investigate the relationship between quality life (QOL) and various aspects denture function. At first, questionnaire visual analog scale 16 question items concerning and/or eating problems, present state health, physical wellbeing, satisfaction, QOL developed. To...

We report the preparation of new ferroelectric liquid crystals, 4-(2-methylalkanoyl)phenyl 4'-alkyloxybiphenyl-4-carboxylates, and measurements their physical properties. The dependence magnitude spontaneous polarization on alkyl chain length is observed. 4-(2-Methyloctanoyl)phenyl 4'-octyloxybiphenyl-4-carboxylate shows extremely large polarization, 293 nC/cm 2 (at 62°C) 403 39°C).
Purpose: Preoperative nutritional status may impact surgical outcome and prognosis. We evaluated the predictive value of Onodera's prognostic index (O's-PNI) following esophagectomy in esophageal cancer patients. Patients methods: In total, 144 patients undergoing for from April 2010 to May 2015 were evaluated, retrospectively. Eighty-four enrolled this study. O's-PNIs calculated before surgery, discharge, 1, 2, 6 mo after discharge. The relationship between O's-PNI occurrence complications...
