Through thermal annealing above the glass transition temperature, a supertoughened binary blend with highest notched Izod impact strength of 98 KJ/m2 was achieved, which about 52 times that neat polylactide (PLA; 1.9 KJ/m2). The composed biocompatible and biodegradable PLA ethylene–acrylic ester–glycidyl methacrylate terpolymer (EGMA) elastomer at composition 80/20 PLA/EGMA. For one toughened 94 KJ/m2, its tensile elongation break kept 120%. Moreover, this also displayed much higher heat...
Biocompatible and biodegradable polylactide (PLA) composites with supertough mechanical property sufficient flame retardancy were fabricated by employing a facile approach involving reactive blending of PLA ethylene-acrylic ester-glycidyl methacrylate terpolymer (EGMA), the addition aluminum hypophosphite (AHP) as an effective retardant. In consideration balance between retardancy, optimal formula was taking PLA/EGMA 80/20 blend (supertough STPLA) matrix adding 20 wt % AHP (relative to mass...
This contribution reports the results of SHREC 2013 track: Retrieval on Textured 3D Models, whose goal is to evaluate performance retrieval algorithms when models vary either by geometric shape or texture, both. The collection search in made 240 textured mesh models, divided into 10 classes. Each model has been used turn as a query against remaining part database. For given query, was retrieve most similar objects. track saw six participants and submission eleven runs.
A supertoughened ternary polylactide (PLA) blend with high heat deflection temperature was reported in this study. The composed of two major biocompatible and biodegradable polymers, namely, PLA polyamide-11 (PA11), one minor reactive elastomer, ethylene–acrylic ester–glycidyl methacrylate terpolymer (EGMA), as a toughener. Shear processing very rotation speed utilized to prepare the by melt blending. At screw 1000 rpm twin-screw extruder, PLA/PA11/EGMA 40/40/20 displayed simultaneous...
Abstract With the miniaturization, high frequency of electronic devices, and low‐carbon sustainable development, higher requirements are put forward for thermal conductive polyurethane composites in terms comprehensive performance renewable raw materials. Herein, choosing bio‐based (PU) derived from castor oil as matrix, liquid metal (LM) aluminum hydroxide (ATH) hybrid filler, oil‐based PU were developed via high‐speed rotation in‐situ polymerization method. The LM‐ATH filler displayed a...
A series of long-chain branched polylactide (LCB PLA)/poly(D-lactic acid) (PDLA) blends with different low amounts PDLA were prepared by a solution blending method. The formation stereocomplex (SC) crystallites in LCB PLA/PDLA during quenching process was proved differential scanning calorimetry (DSC) and dynamic rheological frequency sweep, the content SC increased as composition increased. morphological evolution crystallization at 130 °C traced polarized optical microscopy (POM),...
In this paper, we present a real-time stereo vision based pose and motion estimation system that will be used for landing an unmanned helicopter on moving target such as ship deck. The algorithm mainly consists of feature extraction task task. 2D planer with regular features defined can significantly simplify the corner detection points matching. To effectively estimate distance between camera carrier is applied. By means sub-pixel location precisions relative improved. We results from...
In this paper a novel eye corner (canthus) detection method is proposed. The based on sematic features which are extracted from the structure and appearance characteristics of canthus. eyelids first fitted to construct an angle model. Based model, one feature proposed characterize difference between inner outer canthus regions, another emphasize role bisector region. two fused in logistic regression classifier detect accurate effectiveness accuracy demonstrated experiments.
In this paper, we propose a reliable method of eye states detection for drowsy driving monitoring. Given restricted local block regions, the Local Binary Pattern (LBP) histogram is extracted and each bin treated as feature eye. An AdaBoost based cascaded classifier then trained to select significant features from large sets classify open or closed. According eye, PERCLOS score measured in real time decide whether driver at state not. Experimental results demonstrate that our algorithm can...
The effects of flowing preformed spherulites on shear-induced melt crystallization behaviors isotactic polypropylene (iPP) had been investigated by using a Linkam shearing cell coupled with an optical microscope, atomic force and rheometer. By quenching iPP to 130 °C for short time, were intentionally obtained. While films heated up temperatures below the nominal melting point (164 °C), various shear conditions applied, then crystalline morphologies during at isothermal temperature 135...

Bisphenol A polycarbonate (PC) is difficult to crystallize. In this study, it was found that PC could rapidly accomplish melt crystallization only within 8 min by laying poly(ethylene glycol) (PEG) film on it. Polarized optical microscope (POM) applied trace the growth of spherulites in PEG/PC double-layer films during isothermal a wide range temperatures, which were above melting temperature for PEG. The dependence spherulitic rate (G) (Tc) followed "bell-shape" curve, just like some other...

Since the first case of human avian influenza A (H7N9) virus infection in 2013, five H7N9 epidemics have occurred China, all which caused severe diseases, including pneumonia and acute respiratory distress syndrome, fatality rates these were as high 30-40%. To control prevalence influenza, an effective vaccine is urgently needed. In present study, we used chitosan recombinant interleukin-2 adjuvant (JY) to promote systemic mucosal immune responses induced by vaccine. Mice immunized...
生态补水是维持和改善白洋淀生态环境的重要途径.为研究生态补水对白洋淀水环境的影响，分别在补水前与补水后采集淀水、河水及地下水样品，分析区域地表水和地下水水化学特征.结果表明：（1）白洋淀补水前、后地表水与地下水的水化学组成中Na<sup>+</sup>为主要阳离子，补水后阴离子以HCO<sub>3</sub><sup>-</sup>为主，淀区南部地表水电导率高；补水后地表水与地下水Ca<sup>2+</sup>、Mg<sup>2+</sup>和HCO<sub>3</sub><sup>-</sup>浓度显著增加，水体电导率降低.（2）补水前地下水为Na-HCO<sub>3</sub>型水，地表水主要为Na-Cl·SO<sub>4</sub>及Na-Cl·HCO<sub>3</sub>类型；补水后地表水与浅层地下水向Ca·Mg-HCO<sub>3</sub>型演化，深层地下水水化学类型基本保持不变.（3）生态补水使白洋淀水位升高，淀区水面积增大，缓解了水资源短缺的问题；同时也使浅层地下水水化学组成发生改变，而深层地下水暂未受到影响.生态补水后，受稀释和混合作用的影响，水体Na<sup...
