In search of politically feasible policy-packages for sustainable passenger transport: insights from choice experiments in China, Germany, and the USA
Authors: Wicki Michael , Fesenfeld Lukas , Bernauer Thomas 
Published: July 2019

Abstract
The main obstacle to making the transportation sector ecologically more sustainable is political feasibility. Effective policy-interventions usually encounter strong public opposition as they interfere in costly ways with people’s daily lives, unveiling a dilemma between political feasibility and environmental policy effectiveness. Evidencing the existence of this dilemma, the literature on attitudes towards different policy instrument types maintains that so-called push measures are less supported by citizens than pull measures, and that market-based instruments tend to be less supported than non-market instruments. While these findings may uphold when considering single policy instruments, whether they continue to do so when considering policy-packages, that is, simultaneously implemented policy-interventions consisting of several policy instruments, remains unclear. To identify politically feasible and effective policy-packages aimed at greening the transportation sector we use choice experiments with representative samples of citizens from China, Germany, and the USA (N = 4′876). Contrary to existing literature, we find that public support does not necessarily depend on the instrument type but rather on specific policy design and is highly context dependent. Moreover, despite significant differences between the three country contexts considered, various combinations of policy measures appear to be both potentially effective and supported by most citizens. Altogether, these results suggest that carefully bundled policy-packages may allow governments to employ instruments that would not be politically feasible if introduced in isolation.

Authors: Xu Changwei , Zhao Jianxin 
Published: July 2019

Abstract
For the preparation of glass-ceramics by iron tailings, the sintering and melting methods have been used in the past, but the two methods are short of high energy consumption. In this test, the sol-gel method has been adopted. Because the sol-gel method requires high purity to prepare raw materials, and there are many impurities in iron tailings, which is inconsistent with the preparation requirements of sol-gel method. Therefore, in this experiment, useful elements in iron tailings were extracted. Iron tailings were obtained by thermal-alkali reaction, and Fe was obtained by acid reaction, so as to prepare Ca-Mg-Al-Si system glass-ceramics. After the preparation of sol-gel, the basic glass was obtained, and after nucleation and crystallization, the microcrystalline glass whose main phase was diopside was obtained.

Abstract
Calcium-phosphate coatings were formed on the commercially pure titanium by the method of microarc oxidation (MAO) from the electrolyte, which additionally contains 2.5-15wt.% solution of chitosan. The surface morphology, wettability and elasticity of the formed coatings were investigated. It is shown that the addition of chitosan to the electrolyte composition increases porosity and elasticity of the coatings.
Study on Preparation and thermal reflective properties of energy saving pigments with selective solar reflection
Authors: Li Yunlong , Yang Yuanquan 
Published: July 2019

Abstract
Currently, the color of common reflective insulation coating is mainly white, but the white color coating is monotonous and its resistance is poor, moreover, the reflective performance tends to drop after pollution. In addition, color coating has the advantages of anti-dirty and beautiful appearance, so study on colored paint is of great significance. Based on the principle of three-tone color, the effect of thermal reflective pigments on the near-infrared reflectance of color reflective heat-insulating coatings was studied by blending three kinds of color reflective heat-insulating coatings of orange, green and purple with composite inorganic heat-reflective pigments as raw materials. The results show that the thermal insulation effect of heat-reflective pigments is significantly improved, and the near-infrared reflectance of green pigments can be increased by about 25%. The thermal reflection thermal insulation coating of the green system is 2.78 times higher than that of the same color common thermal insulating coating.

Abstract
Nowadays, anthocyanins have become an interesting topic of much scientific research and act as potential sources of eco-friendly natural food dyes and their helpful effects on human health.. The purpose of the present article was to apply conventional extraction methods of pigments from Butterfly pea (Clitoria ternatea L.Flowers) in Southern Vietnam were tested to extract anthocyanins. The effects of various factors, including the solvent concentration, extraction time, temperature, and solvent/material ratio on the extraction total anthocyanins from Butterfly pea were investigated. In this study, the concentration of monomeric anthocyanins was completed by the spectrophotometry pH differential method.The highest recovered anthocyanin level was achieved with 50 % ethanol (143.49 mg/L), while the lowest one was obtained with water (90.9 mg/L). The extraction yield was significantly affected by temperature and the excellent condition was 60°C. The extraction yield raised with increasing of solvent/material ratio until equilibrium has arrived at the optimal ratio of 25:1 (mL/g). The extraction yield increased first and then decreased with an extension in time values.
Equivalent moisture diffusion coefficient of fiber reinforced composites
Authors: Zhu Libao , Li Yongqing 
Published: July 2019

Abstract
Total diffusion time and the total moisture absorption amount were proposed as the measurement standards of equivalent coefficients for composites moisture diffusion with impermeable fibers. Representative volume element (RVE) models and 2D transient finite element models of unidirectional fiber reinforced composites were established and the accuracy of the RVE model for calculating the equivalent diffusivity was verified. The influences of fiber volume fraction, fiber arrangement and interfaces on the equivalent moisture diffusivity were investigated using the RVE models. The results show that the equivalent moisture diffusivity decreases with the increase of fiber volume fraction. The equivalent moisture diffusivity of random fiber distribution is smaller than that of the periodic fibers distribution, and this difference can be neglected when the fiber volume fraction is relative small. The interfaces with higher diffusivity than matrix will apparently increase the composites diffusivity.

Published: July 2019

Abstract
Enormous interest has been focused on metal oxides in its photocatalytic capabilities toward oxidizing organic dyes and environmental remediation. Zinc oxide (ZnO), titanium dioxide (TiO2) and iron oxide (Fe3O4) have been used as the heterogeneous photocatalysts to photodegrade three organic dyes, which are methylene blue (MB), phenol red (PR) and methyl orange (MO). Series of 3.0 ml dyes samples in aqueous solutions were placed into a UV chamber under UV-C (254 nm) light irradiation. The oxides powder was characterised by XRD, FESEM and TEM analysis, where ZnO nanoparticles was in hexagonal wurtzite crystal structure (SG: P63mc) with average crystalline size of (91 ± 12) nm and TiO2 nanoparticles was pure anatase of tetragonal crystal structure (SG: I4/
a

md) with average crystalline size of (117 ± 16) nm. Fe3O4 nanoparticles was in cubic spinel crystal structure with average crystalline size of (62.1 ± 5.7) nm. The photocatalyst loading (0.5 – 3.5wt%), initial dye concentration (MB: 2 – 12 ppm, PR: 8 – 48 ppm, MO: 12 – 32 ppm) and irradiation duration on the decolourisation of dye samples were examined. Based on time requirement, the photocatalytic decolourisation rate increased with increasing metal oxide loading and decreased with the increasing of the initial dye concentration. The superior photocatalyst was ZnO with a loading of 2.5 wt% followed by TiO2 (3.0 wt%) and least photocatalytic capability was Fe3O4 (3.0 wt%). On the other hand, the most photostable dye is MO followed by PR and MB.

Published: July 2019

Abstract
This paper studied the effects of electrochemical chloride extraction (ECE) on the bonding properties of corroded reinforced concrete with the anode of Magnesium phosphate cement (MPC) bond CFRP. The results indicated that ECE can efficiently remove the chloride ions in the concrete. The interfacial bonding properties of steel-concrete decreased with the increase of chloride removal current density. Proper corrosion ratio of steel bars can reduce the bonding strength loss caused by ECE treatment.

Published: July 2019

Abstract
As an important parameter in application of the Statistical Energy Analysis (SEA), loss factor can measure damping characteristics of a system and determine the ability of vibration energy dissipation. First, the experimental models of steel plate structures are established. And then, the loss factor test is carried out based on transient state decay method. Finally, the variation characteristics of loss factor with medium, thickness and size of structures are explored. The results show that: (1) The loss factor of steel plates has the characteristics that larger at low frequency and small at high frequency, it decreases gradually with the increase of frequency. (2) For the same structure, the loss factor tested in water is greater than the loss factor tested in air. (3) The loss factor increases with the raise of thickness of plates when its cross-sectional dimension is constant.

Abstract
Hydrodynamic noise is one of the main sound source of underwater vehicle. Flow noise and flow-excited noise are important part of hydrodynamic noise. In this paper, large eddy simulation is applied to simulate the flow field around a cone-column combined structure to obtain dipole sound source and turbulence fluctuating pressure. The surface pressure distribution is validated by experiment measured data. Structure dynamic response can be obtained by solving fluid-structure coupling equation. The flow noise and flow-excited noise of the structure are calculated according to acoustic analogy theory. From the numerical result, it can be seen the spectra characteristic of flow-excited noise is different from flow noise. The flow-excited noise obviously increases when system resonance occurs.

Authors: Liu Yonghui , Yi Fengyan , Zhou Changfeng , Tao Lili 
Published: July 2019

Abstract
Ultrasonic heat meter is widely used in heat metering, and its measurement accuracy depends on the flow characteristics of the reflected channel. In this paper, LES (Large Eddy Simulation) method is used to calculate the flow field of the ultrasonic heat meter at low Reynolds number. Through the analysis of the flow field, it is shown that the velocity gradient near the cylindrical reflector is larger, especially at the tail of the first cylindrical reflector; the eddy formed by the flow can scour the reflecting surface and prevent scaling; the average linear velocity over time of the reflecting channel is obtained by the calculation results. The range of velocity variation is 0.609%.
Innervated Dorsalis Pedis Advancement Flap for Burn Foot Contractures
Authors: Eubanks Ryan D , Bowker Harold Dean , Al-Mufarrej Faisal 
Published: July 2019

Abstract
Dorsal foot burns in children often result in contractures with hyperextension of the toes and secondary gait disturbances. Skin grafting a wound bed after contracture release can result in early recurrence. Adequate contracture release often requires tenolysis and/or joint releases that may be prohibitive of skin grafting and require flap coverage. Local flaps are often dismissed as inadequate. Free flaps and distraction techniques have both been described as difficult in the pediatric foot. We describe a single-stage V-Y advancement dorsalis pedis (DP) based fasciocutaneous flap technique that releases dorsal foot contractures in children without donor sites by recruiting tissue from the anterior ankle to the dorsal forefoot. DP-based flaps have not been described before in forefoot burn contracture release. The flap is performed on three children (ages 4–9 years) with unilateral dorsal feet contractures. Each child suffered from gait disturbance due to toe hyperextension. Three to four centimeters of advancement was obtained with each child. Contractures involved all toes but were worst in the second toe for all patients. Extensor tenolysis and/or metatarsal joint releases were performed in each case. Surgeries were performed as an outpatient with minimal postoperative pain. Postoperative leg splinting was not performed. All patients’ surgical sites healed without complication and with complete correction of contractures. Improved gait was noted postoperatively. The V-Y DP perforator advancement is a safe, effective, and reliable technique for dorsal foot burn contracture release in children without need for donor site or prolonged recovery.

AbstractThe inhibitory effect of Chrysomya rufifacies (Macquart) and Cochliomyia macellaria (Fabricius) larval excretions–secretions (ES) on Staphylococcus aureus was determined using a portable colorimetric method without the need for any dedicated spectral instrument. Polystyrene 96 well microplates were used and 100 μl of the bacterial inoculum (5 × 105 CFU/ml) plus 100 μl of the dipteran exosecretions at different concentrations were added to each well. Subsequently, 50 μl of a 1% solution of the triphenyl tetrazolium chloride stain was added to each well to determine the bacterial viability. The color development in each well was measured with the ImageJ software S. aureus was exposed to different concentrations of the ES of both species individually. At a concentration of 800 ppm ES of C. rufifacies or Co. macellaria, bacterial growth was inhibited 97.45 ± 1.70% and 82.21 ± 1.88%, respectively. As expected, exposure to a lower concentration (i.e., 50 ppm) was less inhibitory (C. rufifacies ES, 77.65 ± 4.25% and Co. macellaria ES, 43.54 ± 4.63%). This study demonstrates for the first time the bactericidal activity of C. rufifacies and Co. macellaria ES against S. aureus. This finding is promising as it could result in the identification and synthesis of proteins capable of suppressing pathogen development in wounds. Additionally, the proposed method can simplify the use of expensive laboratory instruments for antimicrobial activity determination.

Abstract
Surveillance for blood-fed female mosquitoes was performed between August 2015 and February 2016 at sites along the periphery of the Aripo Savannas Environmentally Reserve (ASSR) located in northeastern Trinidad, West Indies. We collected engorged female mosquitoes representing 13 species. DNA extractions from dissected abdomens were subjected to PCR amplification with three primer pairs targeting the mitochondrial cytochrome oxidase I and cytochrome b gene sequences. High-quality sequence information and host identification were obtained for 42 specimens representing eight mosquito species with at least one primer combination. A broad range of vertebrates including humans were identified, but the majority were nonhuman mammals, both domestic and wild. Domestic dogs were the most common host and may represent potential sentinel species for monitoring local enzootic arbovirus activity in Trinidad. Culex declarator Dyer and Knab and Culex nigripalpus Theobald were the most common blood-fed mosquito species comprising 79.1% of the total number identified. These species obtained blood meals from birds, nonhuman mammals, and human hosts, and therefore pose significant risks as potential bridge vectors for epizootic arbovirus transmission in the ASSR area as well as other sylvan areas in Trinidad. These data represent the first such results for Trinidad.

Abstract

Background
Cancer screening is a complex process encompassing risk assessment, the initial screening examination, diagnostic evaluation, and treatment of cancer precursors or early cancers. Metrics that enable comparisons across different screening targets are needed. We present population-based screening metrics for breast, cervical, and colorectal cancers for nine sites participating in the Population-based Research Optimizing Screening through Personalized Regimens consortium.

Methods
We describe how selected metrics map to a trans-organ conceptual model of the screening process. For each cancer type, we calculated calendar year 2013 metrics for the screen-eligible target population (breast: ages 40–74 years; cervical: ages 21–64 years; colorectal: ages 50–75 years). Metrics for screening participation, timely diagnostic evaluation, and diagnosed cancers in the screened and total populations are presented for the total eligible population and stratified by age group and cancer type.

Results
The overall screening-eligible populations in 2013 were 305 568 participants for breast, 3 160 128 for cervical, and 2 363 922 for colorectal cancer screening. Being up-to-date for testing was common for all three cancer types: breast (63.5%), cervical (84.6%), and colorectal (77.5%). The percentage of abnormal screens ranged from 10.7% for breast, 4.4% for cervical, and 4.5% for colorectal cancer screening. Abnormal breast screens were followed up diagnostically in almost all (96.8%) cases, and cervical and colorectal were similar (76.2% and 76.3%, respectively). Cancer rates per 1000 screens were 5.66, 0.17, and 1.46 for breast, cervical, and colorectal cancer, respectively.

Conclusions
Comprehensive assessment of metrics by the Population-based Research Optimizing Screening through Personalized Regimens consortium enabled systematic identification of screening process steps in need of improvement. We encourage widespread use of common metrics to allow interventions to be tested across cancer types and health-care settings.

ABSTRACT
Gastrobronchial fistulae (GBF) following minimally invasive oesophagectomy (MIO) is a rare entity, with an estimated incidence of 0.3–1.5% according to the published literature. It could present with persistent cough (Ohno’s sign), chest pain, haemoptysis and recurrent pneumonia. Barium swallow examination remains the most sensitive investigation in 78% of the cases; the main stay of management is surgical and in some cases endoscopic (stent insertion). We report a rare case of a GBF 1 month after two-stage MIO for cancer of the gastro-oesophageal junction, which was successfully treated for the first time with an over-the-scope-clip.

On the ridges, undulations & streams in Gaia DR2: Linking the topography of phase-space to the orbital structure of an N-body bar

Abstract
We explore the origin of phase-space substructures revealed by the second Gaia data release in the disc of the Milky Way, such as the ridges in the Vφ-r plane, the undulations in the Vφ-r-Vr space and the streams in the Vφ-Vr plane. We use a collisionless N-body simulation with co-spatial thin and thick discs, along with orbit integration, to study the orbital structure close to the Outer Lindblad Resonance (OLR) of the bar. We find that a prominent, long-lived ridge is formed in the Vφ-r plane due to the OLR which translates to streams in the Vφ-Vr plane and examine which closed periodic and trapped librating orbits are responsible for these features. We find that orbits which carry out small librations around the x1(1) family are preferentially found at negative Vr, giving rise to a ‘horn’-like feature, while orbits with larger libration amplitudes, trapped around the x1(2) and x1(1) families, constitute the positive Vr substructure, i.e. the Hercules-like feature. This changing libration amplitude of orbits will translate to a changing ratio of thin/thick disc stars, which could have implications on the metallicity distribution in this plane. We find that a scenario in which the Sun is placed close to the OLR gives rise to a strong asymmetry in Vr in the Vφ-Vr plane (i.e. Hercules vs. ‘the horn’) and subsequently to undulations in the Vφ-r-Vr space. We also explore a scenario in which the Sun is placed closer to the bar corotation and find that the bar perturbation alone cannot give rise to the these features.
