Authors: Nuanwat W , Pattananuwat P 
Published: August 2019

Abstract
In this work, polypyrrole coated onto zinc surface anode electrode was successfully prepared via cyclic voltammetry deposition. The different PPy thickness layer on zinc electrode is controlled by the different numbers of deposited cycles at 3, 5, 7 and 10 cycles. The surface morphology development of polypyrrole nano/micro structure covering on zinc surface was examined by Scanning Electron Microscopy-Energy Dispersive X-Ray Spectroscopy. The electrochemical activity of polypyrrole coated zinc electrode is characterized by linear polarization, cyclic voltammetry and galvanic static charge-discharge, indicating that the anti-corrosion PPy surface covering on Zn electrode can yield the highest value of corrosion inhibition efficiency of 67% and serve as high redox layer to improve the charge performance.

Abstract
PLA and PBS have more attention from many industries including textiles industry because there are biopolymer, which have eco-friendly. This research aims at fabricating biodegradable fibers from poly (lactic acid) (PLA) blended with poly (butylene succinate) (PBS). PLA and PBS were blended in a twin-screw extruder at various PBS contents 0 to 20 wt%. The blended fibers were then prepared by the melt spinning using a multifilament spinneret. The mechanical, thermal, and morphological properties were characterized by tensile testing, differential scanning calorimetry, and scanning electron microscopy. The results indicate that, at PBS content in PLA of 10 wt%, the obtained fiber has the optimal tensile properties. At this ratio, the blends also possesses the highest crystallinity among the blended fibers. Although these two biodegradable polymers are immiscible, but at the optimal ratio the PBS phase is well-dispersed in the PLA matrix phase.

Abstract
This paper investigated the effect of Na2SiO3/NaOH ratio on compressive strength of lateritic soil-bagasse ash geopolymer. Lateritic soil was obtained from Sikhio District, Nakhon Ratchasima. Bagasse ash is a waste from the burning of sugarcane for electricity The lateritic soil to binder ratio was fixed at 85/15. The alkaline activator was composed of sodium silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH) at concentration of 5 M. The Na2SiO3/NaOH ratios were 80/20, 70/30 and 50/50. The compressive strength of lateritic soil-bagasse ash geopolymer samples was evaluated at curing time of 7, 14, 28 and 60 days. It can be seen that the compressive strength of lateritic soil mixed with bagasse ash geopolymer increases as the Na2SiO3/NaOH ratio and curing time increase. The maximum compressive strength of lateritic soil-bagasse ash geopolymer was found at the Na2SiO3/NaOH ratio of 80/20 and curing time of 60 days, which gave maximum compressive strength of 9.84 MPa.

Published: August 2019

Abstract
This paper presents an analysis of fire-damaged circular concrete-filled steel tube (CFST) stub columns confined with fiber-reinforced polymer (FRP) sheets under compression. Three main components in the analysis include (1) 2D heat transfer analysis to predict the temperature distributions in the CFST cross section under ISO-834 standard fire, (2) Post-fire mechanical properties of steel and concrete, and (3) Analytical model that incorporates the confinement effect to predict the load capacity of FRP-confined fire-damaged CFST columns. After validated with existing experimental results, the proposed analysis is employed to investigate the effects of heating period and number of FRP layers on the effectiveness of the FRP confinement method.
SBFE analysis of nano-scale elastic layer with consideration of surface energy effects

Published: August 2019

Abstract
This paper presents an efficient and accurate numerical technique for determining the mechanical response of an infinite elastic layer under surface loading and surface stress effects. The governing equation of the bulk is formulated from the classical linear elasticity theory via a SBFE technique whereas that of the material surface is obtained from a complete version of Gurtin-Murdoch surface elasticity theory. By enforcing the continuity at the interface of the material surface and the bulk, it leads to a system of linear non-homogenous ordinary differential equations governing the nodal functions. A general solution of the resulting system of ODEs is constructed via standard procedures and then used together with the boundary conditions to form a system of linear algebraic equations governing nodal degrees of freedom. To investigate the accuracy and convergence of the proposed method, selected scenarios are solved and obtained numerical results are reported and discussed.

Published: August 2019

Abstract
The paper presents research on the impact of three organic fillers from renewable sources, i.e. ground wheat bran, pumpkin seed husks and peanut shells, constituting production waste of the food industry, on selected mechanical and thermal properties of composite injection moldings based on LDPE. The basic strength properties were tested in a static tensile test, hardness and heat deflection temperature, Vicat softening point, and the microscopic structure of the obtained polymer compositions was analysed. The tests were carried out with a different mass content of fillers of 0, 5, 10, 15 and 20% and variable size of filler grains. Samples for testing were obtained in the injection molding process. An increase in the Young’s modulus and hardness as well as a decrease in the remaining tested strength properties along with an increase in the filler‘s share content were found.

Historical Persistence of Alcohol-Induced Mortality in the Russian Federations: Legacy of Early Industrialization
Authors: Kozlov Vladimir , Libman Alexander 
Published: August 2019

AbstractAimsThe study aims to investigate insofar regional differences in alcohol-induced mortality in Russia, which emerged during the early industrialization of the country, persisted over a prolonged period of time (from late nineteenth to early twenty-first century), surviving fundamental political and social changes Russia experienced.MethodsMultivariate regression models with historical and contemporary data on alcohol-induced mortality in Russian regions were estimated to document the persistence of spatial patterns of mortality, as well as to identify the possible mediating variables. Numerous robustness checks were used to corroborate the results.ResultsAlcohol-induced male mortality in Russian regions in 1880s–1890s is significantly and strongly correlated with male mortality due to accidental alcohol poisoning in Russian regions in 2010–2012. For female mortality, no robust correlation was established. The results for male mortality do not change if one controls for a variety of other determinants of alcohol-induced mortality and are not driven by outlier regions. Consumption of strong alcohol (in particular vodka) appears to be the mediator variable explaining this persistence.ConclusionsHazardous drinking behavioral patterns, once they emerge and crystalize during the periods of fragmentation of the traditional society and the early onsets of modernization and urbanization, can be extremely persistent. Even highly intrusive policy interventions at a later stage (like those of the Soviet government) may turn out to be insufficient to change the path-dependent outcomes.
A short argument for truthmaker maximalism
Authors: Jago Mark 
Published: August 2019

Abstract
Each truth has a truthmaker: an entity in virtue of whose existence that truth is true. So say truthmaker maximalists. Arguments for maximalism are hard to find, whereas those against are legion. Most accept that maximalism comes at a significant cost, which many judge to be too high. The scales would seem to be balanced against maximalism. Yet, as I show here, maximalism can be derived from an acceptable premise which many will pre-theoretically accept.
Do vampire bats groom others based on need?
Authors: Narizano Hugo , Carter Gerald G 
Published: August 2019

AbstractAllogrooming provides a window into the social lives of many group-living mammals and birds. The fitness benefits of allogrooming are encouraged by proximate mechanisms that make it physiologically rewarding for both actors and receivers. However, receivers might not always benefit from allogrooming. Some allogrooming decisions might be the actor’s response to cues of the recipient’s need. Other decisions might only be caused by the actor’s motivational state. To test these ideas, we studied what triggers allogrooming in common vampire bats. In test 1, subjects that had experimentally disturbed and wetted fur were more likely to be allogroomed, even when controlling for increased self-grooming. In test 2, allogrooming rates were elevated not only by receiver self-grooming (a cue for receiver need) but also by the actor’s previous self-grooming. Both effects were significantly greater than the effect of self-grooming by third parties. Interestingly, we detected a negative interaction: the positive effect of receiver need on allogrooming was smaller when the actor was previously self-grooming. This is consistent with the hypothesis that there are “receiver-driven” allogrooming decisions, which are responses to recipient need, and “actor-driven” decisions, which are not. We predict that receiver-driven allogrooming will bestow greater benefits to recipients compared with actor-driven allogrooming.

Abstract
Analysis of plant growth regulators (PGRs) should be approached by considering their extremely low concentrations and serious interfering effects that result from the matrix of various plant tissues. In the current research, the separation and simultaneous determination of different classes of phytohormones in 14 seaweeds collected from Turkey seashores were achieved by using solid-phase extraction (SPE) followed by a rapid and sensitive liquid chromatography tandem mass detection method. OASIS HLB (Hydrophilic-Lipophilic Balance) cartridges were successfully used for SPE process to eliminate the matrix effect and enhance the PGRs including zeatin, benzyl amino purine, indole-3-acetic acid, abscisic acid and gibberellic acid within partially different polarities. Based on the optimized experimental conditions, the method presented excellent performance related to linearity (r, 0.9996–0.9999) within the ranges of 0.5–500 ng/mL, relative standard deviation values ((1.43–2.01) for intraday and (2.36–3.50) for interday)), the limit of detection (0.01–0.84 μg/L) and the limit of quantification (0.02–2.76 μg/L). The obtained results confirm that the SPE–liquid chromatography/tandem mass spectrometry method performed is highly effective and convenient for routine analyses of trace amounts of the tested phytohormones in seaweeds and any other plant samples as well.
Stochastic Gradient Descent–Whale Optimization Algorithm-Based Deep Convolutional Neural Network To Crowd Emotion Understanding
Authors: Ratre Avinash 
Published: August 2019

AbstractCrowd emotion understanding is an interesting research area that assists the security personnel to read the emotion/activity of the crowd in the locality. Most of the traditional methods utilize the low-level visual features to understand the crowd emotions that extend the gap between the low- and the high-level features. With the aim to develop an automatic method for emotion recognition, this paper utilizes the deep convolutional neural network (deep CNN). For the effective emotion recognition, it is essential to select the key frames of the video using the wavelet-based Bhattacharya distance. The key frames are fed to the space-time interest points descriptor that extracts the features and forms the input vector to the classifier. Deep CNN is trained using the proposed Stochastic Gradient Descent–Whale Optimization Algorithm, which is the unification of the standard stochastic gradient descent algorithm with whale optimization algorithm. The proposed classifier recognizes the emotions of the crowd, such as angry, escape, fight, happy, normal, running/walking and violence. The analysis of the method proved that the proposed approaches acquired a maximal accuracy, specificity and sensitivity of 0.9693, 0.9936 and 0.9675, respectively.

AbstractAimsWe previously reported that increased protein O-GlcNAcylation in diabetic mice led to vascular rarefaction in the heart. In this study, we aimed to investigate whether and how coronary endothelial cell (EC) apoptosis is enhanced by protein O-GlcNAcylation and thus induces coronary microvascular disease (CMD) and subsequent cardiac dysfunction in diabetes. We hypothesize that excessive protein O-GlcNAcylation increases p53 that leads to CMD and reduced cardiac contractility.Methods and resultsWe conducted in vivo functional experiments in control mice, TALLYHO/Jng (TH) mice, a polygenic type 2 diabetic (T2D) model, and EC-specific O-GlcNAcase (OGA, an enzyme that catalyzes the removal of O-GlcNAc from proteins)-overexpressing TH mice, as well as in vitro experiments in isolated ECs from these mice. TH mice exhibited a significant increase in coronary EC apoptosis and reduction of coronary flow velocity reserve (CFVR), an assessment of coronary microvascular function, in comparison to wild-type mice. The decreased CFVR, due at least partially to EC apoptosis, was associated with decreased cardiac contractility in TH mice. Western blot experiments showed that p53 protein level was significantly higher in coronary ECs from TH mice and T2D patients than in control ECs. High glucose treatment also increased p53 protein level in control ECs. Furthermore, overexpression of OGA decreased protein O-GlcNAcylation and down-regulated p53 in coronary ECs, and conferred a protective effect on cardiac function in TH mice. Inhibition of p53 with pifithrin-α attenuated coronary EC apoptosis and restored CFVR and cardiac contractility in TH mice.ConclusionsThe data from this study indicate that inhibition of p53 or down-regulation of p53 by OGA overexpression attenuates coronary EC apoptosis and improves CFVR and cardiac function in diabetes. Lowering coronary endothelial p53 levels via OGA overexpression could be a potential therapeutic approach for CMD in diabetes.

AbstractBackground and AimsAlthough the mechanisms underlying the formation of intestinal fibrostrictures in Crohn’s disease [CD] are not fully understood, activation of fibroblasts and excessive collagen deposition are supposed to contribute to the development of such complications. Here, we investigated the role of cadherin-11 [CDH-11], a fibroblast-derived protein that induces collagen production in various organs, in intestinal fibrosis.MethodsCDH-11 expression was evaluated in inflammatory [I] and fibrostricturing [FS] CD mucosal samples, ulcerative colitis [UC] mucosal samples, and ileal and colonic control samples, by real-time polymerase chain reaction, western blotting, and immunohistochemistry. CDH-11 expression was evaluated in normal and in CD intestinal fibroblasts stimulated with inflammatory/fibrogenic cytokines. FS CD fibroblasts were cultured either with a specific CDH-11 antisense oligonucleotide [AS], or activating CDH-11 fusion protein and activation of RhoA/ROCK, and TGF-β pathways and collagen production were evaluated by western blotting. Finally, we assessed the susceptibility of CDH-11-knockout [KO] mice to colitis-induced intestinal fibrosis.ResultsCDH-11 RNA and protein expression were increased in both CD and UC as compared with controls. In CD, the greater expression of CDH-11 was seen in FS samples. Stimulation of fibroblasts with TNF-α, interleukin [IL]-6, IFN-γ, IL-13, and IL-1β enhanced CDH-11 expression. Knockdown of CDH-11 in FS CD fibroblasts impaired RhoA/ROCK/TGF-β signalling and reduced collagen synthesis, whereas activation of CDH-11 increased collagen secretion. CDH-11 KO mice were largely protected from intestinal fibrosis.ConclusionsData show that CDH-11 expression is up-regulated in inflammatory bowel disease [IBD] and suggest a role for this protein in the control of intestinal fibrosis.
Exogenous Endowment—Endogenous Reference Point
Authors: Maltz Amnon 
Published: August 2019

Abstract
We develop a model in the presence of categories that creates a link between the agent’s exogenous endowment and an endogenous reference point. The reference point is the best feasible alternative in the endowment’s category. This reference generates a constraint set from which the final choice is made according to utility maximisation. The model predicts category bias, which generalises the status quo bias by attracting the agent to her endowment’s category but not necessarily to the endowment itself. We show that it accommodates recent experimental findings regarding the presence and absence of status quo bias in the realm of uncertainty. In a stylised financial setup, we show that it may lead to a risk premium even with risk-neutral agents.

Abstract
It is generally accepted that radial artery (RA) grafts have better mid-term patency rate compared to saphenous vein grafts. However, the clinical correlates of the improved patency rate are still debated. Observational studies have suggested increased survival and event-free survival for patients who receive an RA rather than a saphenous vein, but they are open to bias and confounders. The only evidence based on randomized data is a pooled meta-analysis of 6 randomized controlled trial comparing the RA and the saphenous vein published by the RADial artery International Alliance (RADIAL). In the RADIAL database, improved freedom from follow-up cardiac events (death, myocardial infarction and repeat revascularization) was found at 5-year follow-up in the RA arm. The most important limitation of the RADIAL analysis is that most of the included trials had an angiographic follow-up in the first 5 years and it is unclear whether the rate of repeat revascularization (the main driver of the composite outcome) was clinically indicated due to per-protocol angiographies. Here, we present the protocol for the long-term analysis of the RADIAL database. By extending the follow-up beyond the 5th postoperative year (all trials except 1 did not have angiographic follow-up beyond 5 years), we aim to provide data on the role of RA in coronary artery bypass surgery with respect to long-term outcomes.

Abstract

OBJECTIVES
Cardiopulmonary bypass (CPB) use is an essential strategy for many cardiovascular surgeries. However, its use and duration have been associated with a higher rate of postoperative complications, such as low cardiac output syndrome due to myocardial oedema and dysfunction. Though Aquaporin water channels have been implicated in myocardial water balance, their specific role in this clinical scenario has not been established.

METHODS
In a consecutive study of 17 patients with severe aortic stenosis undergoing aortic valve replacement surgery, 2 myocardial biopsies of the left ventricle were taken: 1 before and 1 after CPB use. Sociodemographic, clinical and laboratory data were collected. Western blot and immunohistochemistry studies were performed.

RESULTS
After CPB use, there was a mean increase of ∼62% in Aquaporin 1 protein levels (P = 0.001) and a mean reduction of ∼38% in Aquaporin 4 protein levels (P = 0.030). In immunohistochemistry assays, Aquaporin 1 was found lining small blood vessels, while Aquaporin 4 formed a circular label in cardiomyocytes. There were no changes in the localization of either protein following CPB use. During the observed on-pump time interval, there was a 1.7%/min mean increase in Aquaporin 1 (P = 0.021) and a 2.5%/min mean decrease in Aquaporin 4 (P = 0.018). Myocardial interstitial oedema increased by 42% (95% confidence interval 31–54%) after CPB use. Patients who developed low cardiac output syndrome were in the upper half of the median percentage change of Aquaporin expression.

CONCLUSION
Time-dependent changes in cardiac Aquaporin expression may be associated with myocardial oedema and dysfunction related to CPB use.
