Authors: Sun Xiaoli , Tan Yusong , Wu Qingbo , Wang Jing , Shen Changxiang
Published: September 2019

Temporal networks can describe multiple types of complex systems with temporal information in the real world. As an effective method for analyzing such network, temporal graph pattern (TGP) counting has received extensive attention and has been applied in diverse domains. In this paper, we study the problem of counting the TGP in the temporal network. Then, an exact algorithm is proposed based on the time first search (TFS) algorithm. This algorithm can reduce the intermediate results generated in the graph isomorphism and has high computational efficiency. To further improve the algorithm performance, we design an estimation algorithm by applying the edge sampling strategy to the exact algorithm. Finally, we evaluate the performances of the two algorithms by counting both the symmetric and asymmetric TGP. Extensive experiments on real datasets demonstrated that the exact algorithm is faster than the existing algorithm and the estimation algorithm can greatly reduce the running time while guaranteeing the accuracy.
Effects of Essential Oil Citral on the Growth, Mycotoxin Biosynthesis and Transcriptomic Profile of Alternaria alternata
Authors: Wang Liuqing , Jiang Nan , Wang Duo , Wang Meng
Published: September 2019

Alternaria alternata is a critical phytopathogen that causes foodborne spoilage and produces a polyketide mycotoxin, alternariol (AOH), and its derivative, alternariol monomethyl ether (AME). In this study, the inhibitory effects of the essential oil citral on the fungal growth and mycotoxin production of A. alternata were evaluated. Our findings indicated that 0.25 μL/mL (222.5 μg/mL) of citral completely suppressed mycelial growth as the minimum inhibitory concentration (MIC). Moreover, the 1/2MIC of citral could inhibit more than 97% of the mycotoxin amount. Transcriptomic profiling was performed by comparative RNA-Seq analysis of A. alternata with or without citral treatment. Out of a total of 1334 differentially expressed genes (DEGs), 621 up-regulated and 713 down-regulated genes were identified under citral stress conditions. Numerous DEGs for cell survival, involved in ribosome and nucleolus biogenesis, RNA processing and metabolic processes, and protein processing, were highly expressed in response to citral. However, a number of DEGs responsible for the metabolism of several carbohydrates and amino acids, sulfate and glutathione metabolism, the metabolism of xenobiotics and transporter activity were significantly more likely to be down-regulated. Citral induced the disturbance of cell integrity through the disorder of gene expression, which was further confirmed by the fact that exposure to citral caused irreversibly deleterious disruption of fungal spores and the inhibition of ergosterol biosynthesis. Citral perturbed the balance of oxidative stress, which was likewise verified by a reduction of total antioxidative capacity. In addition, citral was able to modulate the down-regulation of mycotoxin biosynthetic genes, including pksI and omtI. The results provide new insights for exploring inhibitory mechanisms and indicate citral as a potential antifungal and antimytoxigenic alternative for cereal storage.

Published: September 2019

Bovine mycotoxicosis is a disorder caused by the ingestion of fungal toxins. It is associated with chronic signs, such as reduced growth rate and milk yield, and causes significant economic cost to the dairy industry. The mycotoxins deoxynivalenol (DON), zearalenone (ZEN), and fumonisin B1 (FB1) are commonly found in grain fed to cattle. Patulin (PA) is a common grass silage contaminant but is also found in grain. The effects of these mycotoxins on cellular function at low concentrations are not well understood. Using Madin–Darby bovine kidney cells we evaluated the cellular response to these mycotoxins, measuring cytotoxicity, de novo protein synthesis, cell proliferation, cell cycle analysis, and also metabolic profiling by 1H NMR spectroscopy. DON, ZEN, and PA induced cytotoxicity, and PA and FB1 induced a decrease in metabolic activity in surviving cells. DON was the only mycotoxin found to have a significant effect on the metabolic profile, with exposed cells showing increased cellular amino acids, lactate, 2-oxoglutarate, 3-hydroxybutyrate, and UDP-N-acetylglucosamine and decreased β-alanine, choline, creatine, taurine, and myo-inositol. Cells exposed to DON also showed reductions in protein synthesis. DON has previously been documented as being a ribotoxin; the results here suggest that exposure of bovine cells to DON causes a decrease in protein synthesis with corresponding cellular accumulation of precursors. Cell proliferation was also arrested without causing apoptosis. It is likely that exposure triggers hypoxic, hypertonic, and ribotoxic responses in bovine cells, and that these responses contribute to reduced productivity in exposed cattle.
Attribution Analysis of Hydrological Drought Risk Under Climate Change and Human Activities: A Case Study on Kuye River Basin in China
Authors: Zhang Ming , Wang Jinpeng , Zhou Runjuan
Published: September 2019

This study conducted quantitative diagnosis on the impact of climate change and human activities on drought risk. Taking the Kuye river basin (KRB) in China as the research area, we used variation point diagnosis, simulation of precipitation and runoff, drought risk assessment, and attribution quantification. The results show that: (1) the annual runoff sequence of KRB changed significantly after 1979, which was consistent with the introduction of large-scale coal mining; (2) under the same drought recurrence period, the drought duration and severity in the human activity stage were significantly worse than in the natural and simulation stages, indicating that human activities changed the drought risk in this area; and (3) human activities had little impact on drought severity in the short duration and low recurrence period, but had a greater impact in the long duration and high recurrence period. These results provide scientific guidance for the management, prevention, and resistance of drought; and guarantee sustainable economic and social development in the KRB.

Published: September 2019

Precipitation on the Qinghai–Tibet Plateau (TP) in southwestern China is subject to interactions between the complex and variable terrain and the sensitive climate. The regional climate is mainly affected by three circulations: westerlies, the South Asian monsoon, and the East Asian monsoon. Spatial and temporal variations in the rainy season onset were characterised based on daily precipitation from 106 meteorological stations on the TP from 1971 to 2015. Using the Theil–Sen Median trend analysis, Mann–Kendall test and mutation detection, the characteristics and reasons for the variations during the rainy season over the plateau over the past 45 years were investigated. The following results were obtained from the analysis: (1) There were obvious regional differences in the rainy season onset over the TP, and the rainy season began on the southeastern plateau and moved northwestward. (2) The TP rainy season underwent a significant mutation in approximately 1997, and following this mutation, the area affected by the delayed rainy season increased. (3) Against the background of global warming, the rainy season trend over the TP was advanced; however, there were still several multiple contiguous concentrated areas on the plateau. (4) Before the rainy season mutation, there were two centres of delayed precipitation on the plateau, which existed primarily due to their location at the end of the plateau water vapour transport channel. After the mutation, the number of delayed precipitation centres on the plateau increased to three and presented a spatially expanding trend, which may be related to the weakening trend in atmospheric circulation.
Can Citizen Science Promote Flood Risk Communication?
Authors: Cheung Wing , Feldman David
Published: September 2019

This article explores the challenges facing citizen science as a means of joining the efforts of scientists and flood-risk affected stakeholders in motivating citizen involvement in identifying and mitigating flood risks. While citizen science harbors many advantages, including a penchant for collaborative research and the ability to motivate those affected by floods to work with scientists in elucidating and averting risk, it is not without challenges in its implementation. These include ensuring that scientists are willing to share authority with amateur citizen scientists, providing forums that encourage debate, and encouraging equal voice in developing flood risk mitigation strategies. We assess these challenges by noting the limited application of citizen science to flood-relevant problems in existing research and recommend future research in this area to meaningfully incorporate a “re-imagined” citizen science process that is based on the participatory theoretical framework. We also discuss one case study where the principles of collaboration, debate, and equal voice were put into play in an effort to apply citizen science and—in the long term—mitigate flood hazards in one set of communities.

Published: September 2019

Although many studies in the literature illustrate the numerous devices and methodologies nowadays existing for assessing the spatial variability within agricultural fields, and indicate the potential for variable-rate irrigation (VRI) in vineyards, only very few works deal with the implementation of VRI systems to manage such heterogeneity, and these studies are usually conducted in experimental fields for research aims. In this study, a VR drip irrigation system was designed for a 1-ha productive vineyard in Northern Italy and managed during the agricultural season 2018, to demonstrate feasibility and effectiveness of a water supply differentiated according to the spatial variability detected in field. Electrical resistivity maps obtained by means of an electro-magnetic induction sensor were used to detect four homogeneous zones with similar soil properties. In each zone, a soil profile was opened, and soil samples were taken and analyzed in laboratory. Two irrigation management zones (MZs) were identified by grouping homogeneous zones on the basis of their hydrological properties, and an irrigation prescription map was built consistently with the total available water (TAW) content in the root zone of the two MZs. The designed drip irrigation system consisted of three independent sectors: the first two supplied water to the two MZs, while the third sector (reference sector) was managed following the farmer’s habits. During the season, irrigation in the first two sectors was fine-tuned using information provided by soil moisture probes installed in each sector. Results showed a reduction of water use by 18% compared to the ‘reference’ sector without losses in yield and product quality, and a grape’s maturation more homogeneous in time.
Treatment Method Assessment of the Impact on the Corrosivity and Aggressiveness for the Boiler Feed Water
Authors: Skoczko Iwona , Szatyłowicz Ewa
Published: September 2019

The aim of the study was the assessment of corrosivity and aggressiveness for boiler feed water. The negative effects of water corrosivity and aggressiveness may include silting up of the steel water supply system and the destruction of boiler equipment touched or washed by such water. They may cause the whole industrial production system to fail or be destroyed. That is why it was important to reach a high water purification level, including the calculation of water aggressiveness and corrosivity indicators. The carried out test showed that the simple system used before the modernization of the industrial water treatment plant is not sufficient to reach clean and stable water. The authors proposed modernization, including additional processes to improve boiler water quality, and designed new devices for water treatment. As a result of the new idea, groundwater taken as raw water was treated in individual and complex processes, such as pre-aeration, filtration, ion exchange (cation and anion exchange resigns), extra aeration, and extra degassing. The conducted research included chemical analyses of raw and treated water. In the conducted studies, the indirect method of water aggressiveness and corrosivity assessment was applied using mathematical calculation of the Langelier Saturation Index (LSI), the Ryznar Stability Index (RI), the Larson–Skold Index (LI), and the Singley Index (SI). The results proved that the new proposed processes for the boiler feed water treatment station allow reaching a high water quality and low level of water aggressiveness and corrosion.

Published: September 2019

To preserve the fun of driving and enhance driving convenience, a smart regenerative braking system (SRS) is developed. The SRS provides automatic regeneration that is appropriate for the driving conditions, but the existing technology has a low level of acceptability and comfort. To solve this problem, this paper presents an automatic regenerative control system based on a deceleration model that reflects the driver’s characteristics. The deceleration model is designed as a parametric model that mimics the driver’s behavior. In addition, it consists of parameters that represent the driver’s characteristics. These parameters are updated online by a learning algorithm. The validation results of the vehicle testing show that the vehicle maintained a safe distance from the leading car while simulating a driver’s behavior. Of all the deceleration that occurred during the testing, 92% was conducted by the automatic regeneration system. In addition, the results of the online learning algorithm are different based on the driver’s deceleration pattern. The presented automatic regenerative control system can be safely used in diverse car-following situations. Moreover, the system’s acceptability is improved by updating the driver characteristics. In the future, the algorithm will be extended for use in more diverse deceleration situations by using intelligent transportation system information.

INTRAUTERINE GROWTH RETARDATION - A REVIEW ARTICLE
Authors: Pham Minh Son , Nguyen Vu Quoc Huy , Tran Dinh Vinh
Published: September 2019

Small for gestational age (SGA) and fetal growth restriction (FGR) is difficult to define exactly. In this pregnancy condition, the fetus does not reach its biological growth potential as a consequence of impaired placental function, which may be because of a variety of factors. Fetuses with FGR are at risk for perinatal morbidity and mortality, and poor long-term health outcomes, such as impaired neurological and cognitive development, and cardiovascular and endocrine diseases in adulthood. At present no gold standard for the diagnosis of SGA/FGR exists. The first aim of this review is to: summarize areas of consensus and controversy between recently published national guidelines on small for gestational age or fetal growth restriction; highlight any recent evidence that should be incorporated into existing guidelines. Another aim to summary a number of interventions which are being developed or coming through to clinical trial in an attempt to improve fetal growth in placental insufficiency.

Published: September 2019

Background: Evaluating improvement of liver fibrosis response after anti HBV therapy in our country until now is very limited, especially in patients with cirrhosis. This study aimed at assessing the respone in liver fibrosis determined by ARFI and its related factors for patients with compensated HBV-related cirrhosis undergoing entecavir therapy.

Subjects and methods: 60 patients with compensated HBV-related cirrhosis were enrolled at Da Nang Hospital from 06/2016 to 06/2018. All received entecavir 0,5mg a day 2 hours after breakfast and followed in 18 months. Liver fibrosis is measured by Acoustic Radiation Forced Imaging (ARFI).

Results: Entecavir treatment may result in improvement of liver fibrosis in 20% after 12 months and 26.67% after 18 months in patients with compensated hepatitis B virus-related cirrhosis. The improvement in fibrosis levels was significant after at least 12 months of treatment. Factors associated with improvement of fibrosis response in this study included AST, ALT, AFP are high, HBeAg (+), low prothrombin time at baseline, and indetectable HBV DNA after 6 months of treatment.

Conclusion: Entecavir treatment may help to improve liver fibrosis in patients with hepatitis B virus-related compensated cirrhosis, but long-term treatment is needed.

Published: September 2019

Knowledge of genetic diversity among available parental lines is fundamental for successful hybrid maize breeding. The aims of this study were to estimate (1) genetic similarity (GS) and genetic distance (GD) (based on Jaccard index) in four maize inbreed lines; (2) to classify the lines according to their GD and GS; (3) to determine hybrid performance based on GD and heterosis for yield ability in 4x4 full diallel system. We used morphological description and AFLP (amplified fragment length polymorphisms) for estimation genetic polymorphism in four maize inbred lines. We estimated the applicability of genetic similarity in SC and reciproc hybrids for prediction of their performance.Three primer combinations were used to obtain AFLP markers, producing 207 bands, 70 of whit were polimorphic. The dendogram based on genetic similarities (GS) and genetic distance (GD) and morphological description separated four inbred lines into well-defined groups. Morphological description just with AFLP analysis showed reliable results. In view of genetic distance, the UDL 1 line and their linear and reciprocal crosses showed significant heterosis effect, which was confirmed by heterosis calculation based on grain yield.
Nitrogen Supplying Capacity of Brown Forest Soil under Different Cropping Practices and 0.01 M CaCl2 Soluble Organic Nitrogen
Authors: Lazányi János , Loch Jakab , Henzsel István
Published: September 2019

The best known and most remarkable example of continuous production in Hungary is the Westsik’s crop rotation experiment, which was established in 1929, and is still in use to study the effects of organic manure treatment, to develop models, and predict the likely effects of different cropping systems on soil properties and crop yields. In this respect, Westsik’s crop rotation experiment provides data of immediate value to farmers concerning the applications of green, straw and farmyard manure, as well as data sets for scientific research.Although commonly ignored, the release of nitrogen by root and green manure crops has a significant impact on soil organic matter turnover. The design of sustainable nitrogen management strategies requires a better understanding of the processes influencing nitrogen supplying capacity, as the effects of soil organic matter on soil productivity and crop yield are still very uncertain and require further research. In the treatments of Westsik’s crop rotation experiment, nutrients removed from soil through plant growth and harvesting are replaced either by fertilisers and/or organic manure. Data can be used to study the nitrogen supplying capacity of soil under different cropping systems and its effect on the 0.01 M CaCl2 soluble organic nitrogen content of soil.The aim of this paper is to present data on the nitrogen supplying capacity of brown forest soil from Westsik’s crop rotation experiment and to study its correlation with hundredth molar calcium-chloride soluble organic nitrogen. The main objective is to determine the effects of root and green manure crops on the nitrogen supplying capacity of soil under different cropping systems. The nitrogen supplying capacity was calculated as a difference of plant uptake, organic manure and fertiliser supply.The 0.01 M CaCl2 soluble organic nitrogen test has proved reliable for determining the nitrogen supplying capacity of soils. Brown forest soils are low in organic matter and in the F-1 fallow-rye-potato rotation, the nitrogen supplying capacity was 15.6 kg/ha/year. 0.01 M CaCl2 soluble organic nitrogen content was as low as 1.73 mg/kg soil. Roots and green manure increased the nitrogen supplying capacity of soil by more than 100%. This increase is caused by lupine, a legumes crop, which is very well adapted to the acidic soil conditions of the Nyírség region, and cultivated as a green or root manure crop to increase soil fertility.
The Examination of the Effects of Value Modifying Factors on Dairy Farms
Authors: Horváth József , Kovács Sándor
Published: September 2019

We wish to present a method to quantify the value modifying effects when comparing animal farms. To achieve our objective, multi-variable statistical methods were needed. We used a principal component analysis to originate three separate principal components from nine variables that determine the value of farms. A cluster analysis was carried out in order to classify farms as poor, average and excellent. The question may arise as to which principal components and which variables determine this classification.After pointing out the significance of variables and principal components in determining the quality of farms, we analysed the relationships between principal components and market prices. Some farms did not show the expected results by the discriminant analysis, so we supposed that the third principal component plays a great role in calculating prices. To prove this supposition, we applied the logistic regression method. This method shows how great a role the principal components play in classifying farms on the basis of price categories.

Published: September 2019

Design language as a form of non-verbal communication is comprised of shapes, colour, texture, pattern, etc. These elements of design language are the penultimate way of communication for designers, especially industrial and product designers. It is the cue that guides the consumer on how to navigate and behave with a product. In relation with motorcycle design, the author investigated on the design language of various motorcycle designs, including how different types of motorcycles for different use could significantly alter the whole design language. This research was carried out with the elements of design language in mind in order to understand it a little further and how it can assist the design process.

Smoothed transition curve for railways
Authors: Koc Władysław
Published: September 2019

The work draws attention to the existing situation in the area of transition curves
used in the geometric layouts of the railway track. Difficulties in the practical implementation
and maintenance of very small horizontal ordinates of the transition curve and the ordinates of
the gradient due to cant in the initial section, appearing on smooth transition curves, were
indicated. The main reason for this situation was the excessive smoothing of the curvature in
their initial section. Employing the method of curvature identification by differential
equations, a new form of the curve was obtained, which was referred to as the "smoothed
transition curve". A definite advantage of this curve was shown, from the implementation
point of view, over representing the smooth transition curves of the Bloss curve. . It seems
that it could successfully compete with the commonly used clothoid, to which it is similar in
the initial section, while it differs significantly along its further length, especially in the final
section, where it provides a gentle entry from the transition curve into a circular arc.

In this study Juniperus excelsa shavings powder (JESP)
was utilized as an adsorbent for the removal of Basic Blue 41 (BB 41) which is
one of the common basic dyes, from aqueous solution. The adsorption experiments
were carried out in a batch system and effects of initial concentration of dye,
interaction time and temperature were investigated. Langmuir, Freundlich and
Temkin adsorption isotherms were used to model equilibrium data. According to
the results, Freundlich isotherm model becomes more convenient option compared
with Langmuir and Temkin models. Freundlich model coefficients are raise as the
temperature rises, showing that the adsorption process becomes favorable higher
temperature. The kinetic parameters were determined by pseudo first order
(PFO), pseudo second order (PSO) and intra-particle diffusion (IPD) models.
Results indicated that experimental and calculated qe values are matched to
each other. Thus the process fits PSO kinetic model with higher R2
values than other two models. Kinetic constants become closer to both temperatures
and initial concentrations and qe values are increases with increasing
concentration of BB 41. Initial dye concentration elevates from 25 to 100 mg L-1,
dye adsorption capacity onto JESP from 3.06 to 16.53 mg g-1,
respectively. Thermodynamic parameters for instance free energy (ΔG), enthalpy (ΔH) and entropy (ΔS) were
assessed. Enthalpy and entropy of this separation process are determined from
3081.91 J mol-1 and 12.33 kJ mol-1, respectively. The
negative values of ΔG° showed that
this separation process was endothermic and natural. The research results
demonstrate that JESP may be a substitute than pricey adsorbents for dye
removal.

Recibido: 17 de mayo de 2019Aprobado: 14 de junio de 2019 En los años recientes, existe una inclinación posmoderna por hacer las cosas de modo fácil, cómodas y rápidas, de esta forma, la ortodoncia ha percibido el efecto de este fenómeno. Los pacientes demandan tratamientos expeditos, estéticos, donde los ortodoncistas actuales desean realizar de igual forma tratamientos más fáciles y menos comprometidos. En este sentido, se han generado una serie de dispositivos diseñados para cumplir con esta finalidad, donde la adaptación a los cambios es primordial, por lo que cada profesional de la ortodoncia debería incluir en sus consultas todas aquellas técnicas que les permitan implementar tratamientos más eficientes. En este artículo se expone un inventario de técnicas en el último siglo de la práctica ortodontista y las nuevas tendencias que permiten en la actualidad realizar tratamientos con mayor rapidez, estéticas y comodidad sin dejar de lado los principios de la ortodoncia pero si eliminando aquellos que han entrado en obsolescencia.

Sin embargo, esto puede lograrse con la ayuda de un profesional dental calificado y su equipo. Día a día, la ciencia está experimentando grandes revoluciones que están llevando a la humanidad hacia una nueva era de la odontología. Los médicos con décadas de experiencia o el estudiante de historia dental pueden mirar hacia atrás en los avances en odontología y afirmar claramente que la profesión dental ha experimentado una gran cantidad de crecimiento tecnológico. Sin embargo, en comparación con la medicina, la ingeniería biomédica, la automoción y la aeronáutica, las drogas, la fabricación rápida, la electrónica y otras, la odontología parece estar más de una década atrás en la adopción o integración de nuevas tecnologías de manera generalizada. Este artículo de revisión se centra en las diversas perspectivas futuras de la odontología restauradora y sus aplicaciones clínicas.

Recibido: 14 de mayo de 2019Aprobado: 10 de junio de 2019La endodoncia es un tratamiento para reparar y salvar un diente gravemente dañado o infectado en vez de quitarlo. El procedimiento consiste en quitar la zona dañada del diente (la pulpa), limpiarlo y desinfectarlo, y después empastarlo y sellarlo. Las causas comunes que afectan a la pulpa: dientes agrietados, cavidades profundas, un tratamiento dental repetido o trauma. El nombre del tratamiento en inglés, "root canal" (endodoncia), viene de la limpieza de los canales dentro de la raíz del diente. El documento es un artículo de revisión de algunas técnicas actuales de la restauración de dientes endodonciados, con el usos de carillas.

IDENTIFYING THE WAGE GAP BETWEEN MEN AND WOMEN. THE CASE OF GREECE
Authors: Staboulis Miltiadis
Published: September 2019

Gender wage gap is an European and International socioeconomic phenomenon with a negative contribution to the efforts of social cohesion, integrity and creation of a solidarity economy. In national level, efforts for the identification and elimination of the gender pay gap have already started since 1970. Although, the phenomenon of the pay gap was been moderated, it still remains at levels above the European average. The analysis and confrontation of the multifactorial phenomenon requires a holistic approach. Women can actively contribute to employment and economic and social development through the improvement and enhancement of their skills and their general qualifications. However, their skills are often underestimated in respect to their payment and their hierarchy in the labour market. This paper studies the case of Greece by estimating the factors that generate the gender wage gap and the glass ceiling phenomenon through the analysis of micro data from 2010 Earnings Survey provided by the Hellenic Statistical Authority (ELSTAT). We estimate pooled quantile regressions as well as quantile regressions, and we carry out a decomposition analysis by applying the Oaxaca-Blinder decomposition technique. The results reveal that the wage gap is mainly formed due to the discrimination of gender (men and women with the same characteristics receive different wages – female wages are significantly lower). Moreover, we approach the glass ceiling phenomenon which is mainly caused due to personal characteristics of individuals.
