Authors: Liu Guowei , Ma Fengshan , Liu Gang , Zhao Haijun , Guo Jie , Cao Jiayuan
Published: June 2019

Submarine mine water inrush has become a problem that must be urgently solved in coastal gold mining operations in Shandong, China. Research on water in subway systems introduced classifications for the types of mine groundwater and then established the functions used to identify each type of water sample. We analyzed 31 water samples from −375 m underground using multivariate statistical analysis methods. Cluster analysis combined with principle component analysis and factor analysis divided water samples into two types, with one type being near the F3 fault. Principal component analysis identified four principle components accounting for 91.79% of the total variation. These four principle components represented almost all the information about the water samples, which were then used as clustering variables. A Bayes model created by discriminant analysis demonstrated that water samples could also be divided into two types, which was consistent with the cluster analysis result. The type of water samples could be determined by placing Na+ and CHO3− concentrations of water samples into Bayes functions. The results demonstrated that F3, which is a regional fault and runs across the whole Xishan gold mine, may be the potential channel for water inrush, providing valuable information for predicting the possibility of water inrush and thus reducing the costs of the mining operation.

Authors: Malik Sehrish , Kim DoHyeun
Published: June 2019

With the swift growth in tourism all around the world, it has become vital to introduce advancements and improvements to the services provided to the tourists, in order to ensure their ease of travel and satisfaction. Optimal travel route identification and recommendation is one of these amenities, which requires our attention as a basic and much-needed facility to improve the experience of travelers. In this work, we propose an optimal route recommendation mechanism for the prediction of the next tourist attraction and optimal route recommendation to the predicted tourist attraction. The algorithms used in the proposed methodology are neural networks for prediction and particle swarm optimization for finding the optimal route. We design an objective function for the route optimization based on the five route parameters of distance, road congestion, weather conditions, route popularity, and user preference. The data used is the tourism data of Jeju Island from December 2016 to December 2017. The performance analysis in the prediction mechanism is performed based on the accuracy of test data results with varying route sizes, while for route optimization, the obtained results are compared with the non-optimized technique. Also, comparisons analysis is performed by comparing the performance of the applied particle swarm optimization algorithm with an identical system-level implementation of the genetic algorithm, which is one of most widely used optimization algorithms. An extended comparative analysis with some related recommendation system studies is also performed based on key optimization factors in route optimization.

Authors: Povstenko Yuriy , Klekot Joanna
Published: June 2019

The heat conduction equations with Caputo fractional derivative are considered in two joint half-planes under the conditions of perfect thermal contact. The fundamental solution to the Cauchy problem as well as the fundamental solution to the source problem are examined. The Fourier and Laplace transforms are employed. The Fourier transforms are inverted analytically, whereas the Laplace transform is inverted numerically using the Gaver–Stehfest method. We give a graphical representation of the numerical results.

Published: June 2019

A survey including 228 pig feed samples from Spain has been developed, exploring the occurrence of 19 mycotoxins (aflatoxins B1, B2, G1 and G2, ochratoxin A, fumonisins B1 and B2, citrinin, zearalenone, deoxynivalenol, fusarenon X, sterigmatocystin, T-2 toxin, HT-2 toxin, enniatins A, A1, B and B2, and beauvericin). The samples were analysed by solid-liquid extraction followed by liquid chromatography coupled with fluorescence or mass spectrometry detection. Enniatin B was found in 100% of the samples (up to 1200 µg/kg) and beauvericin in more than 90%. Moreover, 40% of samples were contaminated with more than five mycotoxins. This high occurrence is insurmountable and surpasses all previous studies, probably due to the inclusion of emerging mycotoxins, scarcely explored. The majority of the samples (96.9%) were in accordance with EU regulations, which do not address emerging mycotoxins or co-occurrence. These results show that in order to ensure mycotoxin absence, emerging mycotoxins should always be considered.

Ricin, a lethal toxin derived from castor oil beans, is a potential bio-threat due to its high availability and simplicity of preparation. Ricin is prepared according to simple recipes available on the internet, and was recently considered in terrorist, suicide, or homicide attempts involving the parenteral route of exposure. In-depth study of the morbidity developing from parenteral ricin poisoning is mandatory for tailoring appropriate therapeutic measures to mitigate ricin toxicity in such instances. The present study applies various biochemical, hematological, histopathological, molecular, and functional approaches to broadly investigate the systemic effects of parenteral intoxication by a lethal dose of ricin in a murine model. Along with prompt coagulopathy, multi-organ hemorrhages, and thrombocytopenia, ricin induced profound morpho-pathological and functional damage in the spleen, bone marrow, and cardiovascular system. In the heart, diffuse hemorrhages, myocyte necrosis, collagen deposition, and induction in fibrinogen were observed. Severe functional impairment was manifested by marked thickening of the left ventricular wall, decreased ventricular volume, and a significant reduction in stroke volume and cardiac output. Unexpectedly, the differential severity of the ricin-induced damage did not correlate with the respective ricin-dependent catalytic activity measured in the various organs. These findings emphasize the complexity of ricin toxicity and stress the importance of developing novel therapeutic strategies that will combine not only anti-ricin specific therapy, but also will target ricin-induced indirect disturbances.
Repertoire of the Bacillus thuringiensis Virulence Factors Unrelated to Major Classes of Protein Toxins and Its Role in Specificity of Host-Pathogen Interactions
Authors: Malovichko Yury V. , Nizhnikov Anton A. , Antonets Kirill S.
Published: June 2019

Bacillus thuringiensis (Bt) is a Gram-positive soil bacteria that infects invertebrates, predominantly of Arthropoda phylum. Due to its immense host range Bt has become a leading producer of biopesticides applied both in biotechnology and agriculture. Cytotoxic effect of Bt, as well as its host specificity, are commonly attributed either to proteinaceous crystal parasporal toxins (Cry and Cyt) produced by bacteria in a stationary phase or to soluble toxins of Vip and Sip families secreted by vegetative cells. At the same time, numerous non-toxin virulence factors of Bt have been discovered, including metalloproteases, chitinases, aminopolyol antibiotics and nucleotide-mimicking moieties. These agents act at each stage of the B. thuringiensis invasion and contribute to cytotoxic properties of Bt strains enhancing toxin activity, ensuring host immune response evasion and participating in extracellular matrix degeneration. In this review we attempt to classify Bt virulence factors unrelated to major groups of protein toxins and discuss their putative role in the establishment of Bt specificity to various groups of insects.
Establishment of a Cell Culture Model of Persistent Flaviviral Infection: Usutu Virus Shows Sustained Replication during Passages and Resistance to Extinction by Antiviral Nucleosides
Authors: Sempere Raquel Navarro , Arias Armando
Published: June 2019

Chronic viral disease constitutes a major global health problem, with several hundred million people affected and an associated elevated number of deaths. An increasing number of disorders caused by human flaviviruses are related to their capacity to establish a persistent infection. Here we show that Usutu virus (USUV), an emerging zoonotic flavivirus linked to sporadic neurologic disease in humans, can establish a persistent infection in cell culture. Two independent lineages of Vero cells surviving USUV lytic infection were cultured over 82 days (41 cell transfers) without any apparent cytopathology crisis associated. We found elevated titers in the supernatant of these cells, with modest fluctuations during passages but no overall tendency towards increased or decreased infectivity. In addition to full-length genomes, viral RNA isolated from these cells at passage 40 revealed the presence of defective genomes, containing different deletions at the 5’ end. These truncated transcripts were all predicted to encode shorter polyprotein products lacking membrane and envelope structural proteins, and most of non-structural protein 1. Treatment with different broad-range antiviral nucleosides revealed that USUV is sensitive to these compounds in the context of a persistent infection, in agreement with previous observations during lytic infections. The exposure of infected cells to prolonged treatment (10 days) with favipiravir and/or ribavirin resulted in the complete clearance of infectivity in the cellular supernatants (decrease of ~5 log10 in virus titers and RNA levels), although modest changes in intracellular viral RNA levels were recorded (<2 log10 decrease). Drug withdrawal after treatment day 10 resulted in a relapse in virus titers. These results encourage the use of persistently-infected cultures as a surrogate system in the identification of improved antivirals against flaviviral chronic disease.
Covering Aluminum Oxide Nanoparticles with Biocompatible Materials to Efficiently Deliver Subunit Vaccines
Authors: Wang Ning , Qiu Changlu , Chen Minnan , Liu Ting , Wang Ting
Published: June 2019

Subunit vaccines have advantages of good safety, minimal reactogenicity, and high specificity. However, subunit vaccines also show a crucial disadvantage of poor immunogenicity and, therefore, are often formulated with an adjuvant carrier to form a vaccine adjuvant-delivery system (VADS) to enhance their efficacies. Alums, the coarse aggregates of the insoluble aluminum salts, are the conventional adjuvants and have been widely used in clinical vaccines for a long time. Unfortunately, alums also show two main drawbacks of low potency in eliciting cellular immunity, and high reactogenicity to cause unwanted inflammations. Therefore, herein the phospholipid bilayer-coated aluminum oxide nanoparticles (PLANs) and the PEGylated PLANs (PEG-PLANs) were engineered as a VADS to overcome the drawbacks of both subunit vaccines and coarse alums, while synergizing their functions. In vitro experiments demonstrated that, unlike the micron-sized alums, the nanosized PLANs and PEG-PLANs loaded with model antigen of ovalbumin (OVA) showed a high safety profile and were able to promote APC (antigen-presenting cell) uptake and engender lysosome escape for enhancing the MHC (major histocompatibility complex)-I-antigen display. Subcutaneously administered to mice, PLANs and, especially, PEG-PLANs smoothly trafficked into the draining lymph nodes, wherein the densely clustered immune cells were activated in substantial numbers, leading to robust immunoresponses and efficient production of the anti-antigen antibodies and CD8+ T cells. Thus, the aluminum-based nanocarriers, especially the PEG-PLANs, are a promising VADS possessing the potential of eliciting strong and comprehensive immunity against pathogens.
Does Engagement Build Empathy for Shared Water Resources? Results from the Use of the Interpersonal Reactivity Index during a Mobile Water Allocation Experimental Decision Laboratory
Authors: Bradford Lori , Chun Kwok P. , Bonli Rupal , Strickert Graham
Published: June 2019

Currently, there are no tools that measure improvements in levels of empathy among diverse water stakeholders participating in transboundary decision-making. In this study, we used an existing empathy scale from clinical psychology during an Experimental Decision Laboratory (EDL) where participants allocated water across a transboundary basin during minor and major drought conditions. We measured changes in empathy using a pre-test/post-test design and triangulated quantitative results with open-ended survey questions. Results were counter-intuitive. For most participants, levels of the four components of empathy decreased after participating in the EDL; however, significant demographically-driven differences emerged. Qualitative results confounded the problem through the capture of participant perceptions of increased overall empathy and perspective taking specifically. Implications for methodological tool development, as well as practice for water managers and researchers are discussed. Water empathy is a particularly sensitive construct that requires specialized intervention and measurement.

THE METHOD OF SELECTION THE SOLID FINITE ELEMENT MODELS OF LOAD-BEARING SYSTEMS OF MACHINE TOOLS WHEN PERFORMING ENGINEERING ANALYSIS
Authors: Полоз М. , Davidenko Polina , Шевченко А. , Shevchenko Andrey , Ерижокова Е. , Erizhokova Elena
Published: June 2019

The paper presents a methodology for the selection of a solid finite element models for load-bearing systems of machine tools. The technique is based on the analysis of the results of computer simulation of different models of load-bearing systems of three machines with different layouts. The variability of the models is determined taking into account the traction devices and joints in the conjunctions. The traditional approach for modeling the non-ideal joint in the form of elastic elements set is used, despite the fact that modern CAE systems for modeling non-ideal contact in mates offer special contact finite elements. The conducted computational experiments demonstrate that the most accurate model is obtained by using models of traction devices and joints. In this case, the computational model requires significant computational resources. It is found that the exception of the design model of the bearing system of the machine traction devices can lead to an increased modeling error in static problems up to 25 %. The results of modal and dynamic calculations are more resistant to changes in the design model of the machine, as the error of the design parameters does not exceed 10 %. In addition, the computational models of tightened joint, with a stiffness of more than N/m, are not much different from models with ideal contact. It is shown that with an acceptable 25% modeling error, it is preferable to use a computational model of the load-bearing system without taking into account the non-ideal contact and traction devices

Published: June 2019

Today, the task of increasing the drive unit technical characteristics of robot gripping devices is relevant. In many respects, the drive motor and gear unit determine the quality of work of such modules, which can introduce additional elasticity, backlash and friction into the system. In turn, backlash and friction in the control loop decrease the speed and accuracy of the mechatronic module and can cause self-oscillations. However, significant progress in hardware performance of mechatronic and robotic systems makes it possible to more accurately estimate and control the force and torque state parameters in the output link and to carry out active algorithmic compensation for the effects of friction and elasticity.

Such observers are usually based on detailed mathematical models and allows to implement force control without the use of special sensors, which is especially important in advanced gripping devices due to the requirements imposed on the mass-dimensional parameters of the product. Therefore, the purpose of this article is to make a general mathematical model of the robot drive unit with a rational relationship of complexity and accuracy. The models’ parameters should be easily identified from the constituent elements of passport data or the experiment results. The model should allow estimating the state parameters of mechanical transmission in real time; take into account the main friction effects. However, it should be simple enough for analytical conclusion and numerical modeling. As part of the article, various friction models are considered. On the basis of this analysis, a modified friction model is proposed. It makes possible to estimate the state parameters of mechanical transmission in real time. It is built into the general mathematical model of the mechatronic module. The results of mathematical simulation are close to experimental data. The considered drive unit mathematical model can be used to identify the state parameters of the mechatronic module in real time and implement force control based on estimation. In addition, the obtained model allows to conduct mathematical simulation of the robot taking into account the drive unit dynamics.

Characterization of cis-elements in hormonal stress-responsive genes in Oryza sativa
Authors: Saidi Abbas , Hajibarat Zohreh
Published: June 2019

Phytohormones play a key role in plant growth and development. The process of plant’s perception and response to abiotic and biotic stresses is controlled mainly by the phytohormones which act as an endogenous messenger in the regulation of the plant’s status. They can be activated by different signaling pathways in response to environmental stresses. Plants respond to environmental stress through interaction of transcription factors with a handful of cis-regulatory elements (CREs). Some examples of cis elements include abscisic acid-responsive element (ABRE), G-box (CACGTG) element, and W-box. In order to investigate the effects of different hormonal stresses which have a key role in response to biotic and abiotic stresses in rice, microarray data was used. Of the available data, 931 genes revealed significant differences in response to different hormonal stresses such as auxin, cytokinin, abcisic acid, ethylene, salicylic acid, and jasmonic acid. The present results showed that 388 genes were up-regulated, and 543 genes were down-regulated. Most of the genes were up-regulated in response to Indole-3-acetic acid (IAA) hormone. Genes Ontology analysis revealed that they respond to various hormones involved in auxin- responsive genes, auxin-activated signaling pathway and cellular responses to environmental stimuli. G-box had the highest number of cis elements involved in hormonal stress and was regulated by auxin signaling and various stresses. Dehydrin was the only gene up-regulated in response to the six hormones. This gene can be activated in response to abiotic and biotic stresses. As such, dehydrin gene can be used in crop breeding programs to increase tolerance to different environmental stresses in various plant species.

A Novel Stress-Level-Specific Feature Ensemble for Drivers’ Stress Level Recognition
Authors: IŞIKLI ESENER İdil
Published: June 2019

This
paper proposes a novel feature set for drivers’ stress level recognition. The
proposed feature set consists of data-independent and almost uncorrelated feature
pairs for each stress level with very strong intra-class and relatively weak
inter-class correlations, constructed by realizing a correlation analysis on
the popular features studied in the literature. By using the proposed feature
set, a maximum of 100% stress level recognition accuracy is achieved with an
average increment of 24.85% while a mean reduction rate of 88.01% is satisfied
in false positive rate compared to the full feature set. These outcomes clearly
show that the proposed feature set can confidently be integrated into the
driving assistance systems.

Authors: Rufaindah Ervin
Published: June 2019

The use of contraception after childbirth is so important to prevent the occurrence of unwanted pregnancies. Nearly 80% of family planning acceptors choose hormonal birth control, so people are not familiar with hormonal birth control. However, many acceptors complained about the side effects of family planning so that many acceptors dropped out. One of the causes of the number of family planning acceptors dropping out is the lack of understanding of hormonal family planning so that it is necessary to provide health education about family planning and contraceptive methods to increase maternal awareness of using contraception. The purpose of this study was to analyze the effect of homecare giving from midwifery students in trimester III pregnant women on the type of selected birth control method in Malang. This study was an observational study with a cross-sectional approach. The research sample amounted to 67 respondents. Data analysis using the chi-square test. The result of the chi-square test p-value is 0.132> 0.05, which means there is no significant relationship between home care services and the type of family planning method chosen after delivery. It is hoped that students, educational institutions and midwives will jointly improve the quality of services by providing optimal IEC related to family planning and contraception.

AN EVALUATION ON PERFORMANCE OF PCA IN FACE RECOGNITION WITH EXPRESSION VARIATIONS
Authors: Duong Khanh Ngoc Van , Nguyen An Bao
Published: June 2019

Appearance-based recognition methods often encounter difficulties when the input images contain facial expression variations such as laughing, crying or wide mouth opening. In these cases, holistic methods give better performance than appearance-based methods. This paper presents some evaluation on face recognition under variation of facial expression  using the combination of PCA and classification algorithms. The experimental results showed that the best accuracy can be obtained with very few eigenvectors and KNN algorithm (with k=1) performs better than SVM in most test cases.

Vietnamese universities have seen an increase in demand for quality improvement of their programs and teaching performance. However, the degree to which high-quality programs and teaching performance is determined by students’ hardiness in learning, and their assessment in university education. This study was employed to examine the relationships of hardiness and learning outcome, quality of life on students, and quality of university life on students in Tra Vinh University. The study uses Structural Equation Modeling (SEM) and the sample of 341 economic sector students in Tra Vinh University. The findings have  indicated that hardiness in learning has a positive relationship with three elements including (i) learning outcome, (ii) quality of life on students, and (iii) quality of university life on students. Besides that, the results also indicated that three attitudes of commitment, control, and challenge have a direct effect on hardiness, while teacher elements have a powerful impact on the students’ quality of university life. The study also contributes some implications for the improvement of teaching quality and the stimulation for students’ behavioral intention of hardiness and attitudes.
EFFECTS OF NITROGEN AND POTASSSIUM LEVELS ON GROWTH, YIELD AND QUALITY OF BON BON (CATTAIL) IN CA MAU PROVINCE

Published: June 2019

The experimental layout was designed in completely randomized complete block with 4 replicates in the combination of nitrogen levels of 28,8; 60; 90; 120 kg/ha with potassium of 0 and 30 kg/ha in order to investigate the effects of fertilization on growth, yield and quality of bon bon (Cattail) in Ca Mau province. At 90days after planting, treatments with higher levels of nitrogen application increased in plant height, tiller number, weight of edible part, fresh and dry biomass. Variations in nitrogen and potassium levels caused no change in photosynthetic pigments but chlorophyll a content was always about more than triple more than that of chlorophyll b. Potassium contributed to enhancinge plant height, biomass, edible part weight but difference in tiller number was not found between the two levels. Higher levels of nitrogen in combination with potassium not only enhanced biomass yield but also improved quality by increasing levels of soluble sugars and protein in the edible part. The interactions between nitrogen and potassium levels were recognizedpositively affected on growth, yield, and quality of cattail; therefore, it is highly recommended to apply both these nutrients when growing this crop.

The aim of the research is: to study the
morphofunctional characteristics of the peripheral blood
cells of healthy young people of the same age group,
taking into account the dependence on the ecological and
biogeochemical factors of the external environment of
the region of residence and to identify the physiological
mechanisms underlying adaptation to the external
environment.
Materials and methods. there were examined 125
students studied at the North Caucasus Federal University
at the age of 18–21. For the quantitative evaluation of
peripheral blood cells, 15 laboratory parameters were
determined on the MEDONIK M-SERIES hematology
analyzer. Leukocyte analysis was performed on the
MECOS-C3 hardware-software complex.
Results. The analysis of peripheral blood indices revealed
significant shifts in adaptation processes in the direction of
tension in the group of Indian students (P <0.01) and less
critical changes in the compensatory-adaptive mechanisms
of the body in the group of students from Tajikistan
(P <0.05).
Conclusion. As a result of the study, new data have
been obtained indicating a different spectrum of adaptive
reactions of students, which allows the use of peripheral
blood as a test system for assessing the influence of
damaging environmental factors.

Published: June 2019

Friedel–Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.
