Published: April 2019

Ciguatera Fish Poisoning is a worldwide concern caused by the consumption of fish contaminated with ciguatoxins not only in endemic regions in the Pacific Ocean or the Caribbean Sea but also in emerging areas of Macaronesia on the eastern Atlantic. The recent emergence of these toxins in other coastal areas worldwide, prompted the need for the characterization of the risk in these areas. This Ciguatera Fish Poisoning risk has been recently identified as a potential threat in subtropical areas of the Atlantic coast and scientific efforts are being focused in the identification and confirmation of the toxins involved in this potential risk. Neuroblastoma cell assay has been widely used for the evaluation of the toxicity in several marine biotoxin groups, and found to be a very useful tool for toxicity screening. LC-MS/MS has been also used for confirmatory purposes although the main limitation of the advances on LC-MS/MS development is due to commercial unavailability of reference materials and hampers method implementation and validation or even confirmation of the ciguatoxins (CTXs) responsible for the toxic profiles. While neuroblastoma cell assay (N2a) is typically used for toxicity screening as mentioned above, being necessary to confirm this N2a toxicity by LC-MS/MS, this study is designed using N2a as a tool to confirm the toxicity of the fractions obtained corresponding to potential CTXs analogues according to the analysis by LC-MS/MS. With this aim, an amberjack sample (Seriola fasciata) from Selvagen Islads (Portugal) and implicated in Ciguatera Fish Poisoning was analyzed by LC-MS/MS and Caribbean Ciguatoxins were found to be mainly responsible for the toxicity. N2a was used in this work as a tool to help in the confirmation of the toxicity of fractions obtained by HPLC. Caribbean Ciguatoxin-1 was found as the main analogue responsible for the N2a toxicity while three Caribbean Ciguatoxin-1 (C-CTX1) metabolites which contribute to the total toxicity were also identified.
Schistosomiasis in the Philippines: Innovative Control Approach is Needed if Elimination is the Goal
Authors: Olveda Remigio M. , Gray Darren J.
Published: April 2019

In 1996, schistosomiasis due to Schistosoma japonicum was declared eradicated in Japan. In the People’s Republic of China, S. japonicum transmission has been interrupted in the major endemic areas in the coastal plains but the disease persists in the lake and marshland regions south of the Yangtze River. The disease remains a public health problem in endemic areas in the Philippines and in isolated areas in Indonesia. Comprehensive multidisciplinary campaigns had led to eradication of schistosomiasis in Japan and have been successful in the interruption of disease transmission in the major endemic regions of the People’s Republic of China. Unfortunately, the integrated measures cannot be duplicated in schistosomiasis endemic areas in the Philippines because of limited resources. The problem is also more complicated due to the topography in the Philippines and transmission is not seasonal as in China. An innovative approach is needed in the Philippines if schistosomiasis elimination is the goal.
Sensitivity Analysis of Extreme Daily Rainfall Depth in Summer Season on Surface Air Temperature and Dew-Point Temperature
Authors: Sim Inkyeong , Lee Okjeong , Kim Sangdan
Published: April 2019

Looking at future data obtained from global climate models, it is expected that future extreme rainfall will increase in many parts of the world. The Clausius-Clapeyron equation provides a physical basis for understanding the sensitivity of rainfall in response to warming, but the relationship between rainfall and temperature is still uncertain. The purpose of this study is to analyze the sensitivity of extreme daily rainfall depth during the summer season (June–September) to climate change in Korea. The relationship between the observed extreme daily rainfall depth and the surface air temperature (SAT) and dew-point temperature (DPT), which were observed in the 60 sites of the Korea Meteorological Administration, were analyzed. The same analysis was also performed using future data provided in various climate models. In addition, the future trends of extreme rainfall, SAT, and DPT were analyzed using future data obtained from climate models, and the effects of increasing SAT and DPT on future extreme rainfall changes were investigated. Finally, it has been confirmed that using changes in SAT and DPT to look at changes in future extreme rainfall can give more consistent future projection results than using future rainfall data directly.
Integrating XAJ Model with GIUH Based on Nash Model for Rainfall-Runoff Modelling

Published: April 2019

The geomorphologic instantaneous unit hydrograph (GIUH) is an applicable approach that simulates the runoff for the ungauged basins. The nash model is an efficient tool to derive the unit hydrograph (UH), which only requires two items, including the indices n and k. Theoretically, the GIUH method describes the process of a droplet flowing from which it falls on to the basin outlet, only covering the flow concentration process. The traditional technique for flood estimation using GIUH method always uses the effective rainfall, which is empirically obtained and scant of accuracy, and then calculates the convolution of the effective rainfall and GIUH. To improve the predictive capability of the GIUH model, the Xin’anjiang (XAJ) model, which is a conceptual model with clear physical meaning, is applied to simulate the runoff yielding and the slope flow concentration, integrating with the GIUH derived based on Nash model to compute the river network flow convergence, forming a modified GIUH model for flood simulation. The average flow velocity is the key to obtain the indices k, and two methods to calculate the flow velocity were compared in this study. 10 flood events in three catchments in Fujian, China are selected to calibrate the model, and six for validation. Four criteria, including the time-to-peak error, the relative peak flow error, the relative runoff depth error, and the Nash–Sutcliff efficiency coefficient are computed for the model performance evaluation. The observed runoff value and simulated series in validation stage is also presented in the scatter plots to analyze the fitting degree. The analysis results show the modified model with a convenient calculation and a high fitting and illustrates that the model is reliable for the flood estimation and has potential for practical flood forecasting.

Published: April 2019

Water quality control remains an important topic of public health since some diseases, such as diarrhea, hepatitis, and cholera, are caused by its consumption. The microbiological quality of drinking water relies mainly on monitoring of Escherichia coli, a bacteria indicator which serves as an early sentinel of potential health hazards for the population. In this study, an electronic nose coupled to a volatile extraction system (was evaluated for the detection of the emitted compounds by E. coli in water samples where its capacity for the quantification of the bacteria was demonstrated). To achieve this purpose, the multisensory system was subjected to control samples for training. Later, it was tested with samples from drinking water treatment plants in two locations of Colombia. For the discrimination and classification of the water samples, the principal component analysis method was implemented obtaining a discrimination variance of 98.03% of the measurements to different concentrations. For the validation of the methodology, the membrane filtration technique was used. In addition, two classification methods were applied to the dataset where a success rate of 90% of classification was obtained using the discriminant function analysis and having a probabilistic neural network coupled to the cross-validation technique (leave-one-out) where a classification rate of 80% was obtained. The application of this methodology achieved an excellent classification of the samples, discriminating the free samples of E. coli from those that contained the bacteria. In the same way, it was observed that the system could correctly estimate the concentration of this bacteria in the samples. The proposed method in this study has a high potential to be applied in the determination of E. coli in drinking water since, in addition for estimating concentration ranges and having the necessary sensitivity, it significantly reduces the time of analysis compared to traditional methods.

On the conceptual development of the industrial policy of the Eurasian economic Union: the criteria of jointly produced goods of the EAEU and the approach to its definition
Authors: Tkachuk S.P. , Pak A.Yu.
Published: April 2019

The newest stage of post-Soviet Eurasian economic integration associated with the large-scale tasks of making a breakthrough in the economic development of its participants, including the tools of the EAEU, imposes increased requirements for the content and quality of the integration agenda. At the same time, the imperative put forward by the governing bodies of the Union of compliance of the development goals with the operational objectives of maintaining the current macroeconomic stability of the Eurasian Union in the conditions of further growth of sanctions can no longer be a sufficient condition for the advanced development of the EAEU member States. In order to ensure economic growth at a faster pace of development and with a proper synergetic effect for the national economic complexes of the EAEU States, a fundamental basis in the form of a well-thought-out ideologically and structurally sound industrial policy is required.
In this context, the authors of the article touch upon such an essential element of the concept of this policy (the industrial policy of the EAEU, or the Eurasian industrial policy) as the criteria for jointly produced goods of the EAEU; an approach to its definition is proposed. Implementation of this approach, according to the authors, will create conditions for the development of mutually beneficial intra-Union production cooperation and import substitution, for a successful refraction to the post-Soviet realities of the relevant positive experience of the European Union.

Published: April 2019

Poor nutrition causes the prevalence of stunting (short children) to be very high, affecting one in three children 12 - 60 months, which is a proportion of public health problems according to the criteria of the World Health Organization (WHO). The Tanjung Langkat Health Center report on infectious diseases suffered by children under five in the Tanjung Langkat Health Center working area, ARI and Diarrhea is quite high among toddlers, namely 17.7% and 29.8%. This research is an analytic research study with case control design, which is an analytic study concerning how risk factors are studied using a retrospective approach. In other words, the effects (illness or health status) are identified at this time, then identified risk factors exist or occurred in the past. The results showed that children aged 12-60 months who had low birth weight and got stunting in the working area of Tanjung Langkat 58 Padang Puskesmas in 2015 were 15 people (48.39%), while normal children who suffered stunting were 16 people (51, 61%). This research is not in line with other studies which say that stunting children have more history of low birth weight. It is expected that Puskesmas Tanjung Langkat health workers will get children born with low birth weight, so health workers provide information that they have a risk of suffering from stunting (short), and are advised to maintain their health and pay attention to their parenting.

The results of experimental studies to determine the possibility of obtaining carbonized material based on lime-carbonate-calcium compositions using inkjet 3D printing are presented. Some types of materials used as connecting for inorganic binders have been studied. An effective method of hardening the model obtained in the process of 3D printing is determined. The physicomechanical characteristics of prototypes solidified in an environment of high concentration of carbon dioxide are defined. It has been established that artificial carbonization of samples obtained on various types of binders for 90 minutes contributes to the formation of a sufficiently strong structure from insoluble calcium carbonate, a product of carbonation of hydrated lime. In this case, the degree of carbonization depends on the type of binder and its mass fraction in solution. The most effective types of binders are selected and the optimal content of the binders in solution is determined. In result, to ensure the production of materials with sufficient physicomechanical properties, a possibility of obtaining carbonized material by the method of 3D inkjet printing at certain optimal contents of the tested binders is confirmed.

Published: April 2019

This article examines the urban public and business subcenters as secondary elements of the city system, the closest in properties to its main center. The criteria defining the public business subcenters are highlighted. The current trends in the formation of social and business subcenters in large cities and megalopolises are considered. Analysis of world experience is produced. Foreign concepts of spatial development are analyzed on the example of several existing urban subcenters. Various available cartographic materials and literature sources have been studied. They cover the development of urban business centers and various aspects of urban development. The methods of spatial formation of the planning structure of urban public business subcenters are highlighted: the cluster and channel. The development stages of urban subcenters from the territory of concentration of small trade and residential establishments to large-scale multifunctional urban planning formations are presented. The prospects for the development of business subcenters in major cities of the Russian Federation are analyzed and trends are identified: social and business polycentrism, disposition of administrative and business centers on the outskirts of cities and the formation of self-organizing business subcenters, mainly based on shopping and entertainment centers in residential areas. Prospects for development of urban subcenter in a large city are considered on the example of the city of Belgorod. Conclusions are drawn on the need to develop new models of urban public business subcenters taking into consideration the modern planning specifics of large cities and megalopolises of the Russian Federation. Models of urban public business subcenters must meet the requirements of polyfunctionality, to have high architectural and town planning qualities, to take into account the needs of population in the design area and to ensure the sustainable development of the urban periphery.

Published: April 2019

The possibility of increasing efficiency of non-autoclaved foam concrete due to the use of complex binder with mineral components of different composition has been theoretically substantiated and experimentally confirmed. The opportunity to use the anhydrous calcium sulphate as a modifying component of the mixture is proved, which accelerates the setting of the mixture. This allows to "fix" the structure of the aerated concrete mixture with minimal shrinkage deformations. It is shown that the combined use of anhydrite and a mineral additive in the form of a quartz suspension obtained by grinding sand in an aqueous medium leads to a liquefaction of the mixture, which is associated with a decrease in the share of the structure-forming component. From a technological point of view, this will allow obtaining materials with a rational pore structure by optimizing the processes of pores formation. Composite binder with mineral additives is characterized by increased strength with a reduced share of clinker component in comparison with cement. In result, the minimization of shrinkable deformations and improvement of the quality of cellular concrete are ensured

Published: April 2019

To date, miR-148-3p and DNMT1‐recombinant human runt-related transcription factor 3 (RUNX3) axis have been linked to cell proliferation, migration, and invasion; however, their roles and relationships in human glioblastoma multiforme (GBM) are still not clear. Here we found that
the expression of miR-148-3p in glioma tissues was decreased compared with adjacent nontumor tissues and correlated with WHO grade, tumor size, and prognosis as well as DNMT1 and RUNX3 expressions. Compared with NHA cells, the expression of miR-148-3p in U87 and U251 cells was also downregulated
and accompanied with upregulation of DNMT1 and hypermethylation level of RUNX3 promoter region. miR-148-3p overexpression induced apoptosis and cell cycle arrest of U87 and U251 cells, and affected cell migration and invasion. miR-148-3p mimics effectively suppressed the expression of DNMT1
and methylation of RUNX3 promoter, finally upregulating RUNX3 expression. Mechanistically, the 3′-untranslated region (3′-UTR) of DNMT1 was a direct target of miR-148-3p. Overexpression of miR-148-3p or inhibition of DNMT1 induced the expression of E-cadherin and reduced the expressions
of N-cadherin, vimentin, MMP-2, and MMP-9. In conclusion, miR-148-3p directly repressed the expression of DNMT1 and inhibited proliferation, migration, and invasion by regulating DNMT1‐RUNX3 axis and the epithelial‐mesenchymal transition in GBM. Our findings provide a new foundation
for treatment of patients with GBM.

ON ASYMPTOTICS OF A POPULATION MODEL WITH RANDOM MATING
Authors: Skakauskas Vladas
Published: April 2019

This paper deals with a model for an age‐sex structured population consisting of male, single and fertilized female subclasses taking into account a random coupling of sexes (for a period of mating only) and females’ pregnancy. For certain forms of the demographic rates there are presented separable solutions, and the asymptotic behaviour of the general solution is demonstrated.

Published: April 2019

The main objective of this paper is to analyze and develop a GIS system that includes all necessary information obtained by using GPS and mobile GIS techniques as well. Since several techniques for information management exist, the aim is how to integrate them for a sustainable management of vineyards areas in Kosovo. It has been designed a system, which is able to produce maps, make various analyses based on the requests of the specific users and offers trend orientation for decision making. The JAVA programming language has been used. This provides the most possible flexibility in the data flow and data management. The structure of the data base is proposed to be designed in that way that the textual and geometric data have been processed in a unique data base in PostGIS PostgreSQL technology.Web GIS technology presented in this paper, shows an advantage comparing to the desktop based technology since it enables an access in real time. Foremost, the application offers an access depending on the roles and privileges for different users. Development of a WEB application for viticulture management will improve the efficiency and decision making process as well.Results show numerous capabilities of GIS methodologies to manage the agricultural crops, in this particular case, the vineyards. Further, the results provide insight into information management in a single system and serve as a basis for similar researches in other areas of agriculture in the future.

We present a detailed characterization of the 849 broad-line quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Our quasar sample covers a redshift range of 0.1 < z < 4.5 and is flux-limited to i
PSF < 21.7 without any other cuts on quasar properties. The main sample characterization includes: (1) spectral measurements of the continuum and broad emission lines for individual objects from the coadded first-season spectroscopy in 2014, (2) identification of broad and narrow absorption lines in the spectra, and (3) optical variability properties for continuum and broad lines from multi-epoch spectroscopy. We provide improved systemic redshift estimates for all quasars and demonstrate the effects of the signal-to-noise ratio on the spectral measurements. We compile measured properties for all 849 quasars along with supplemental multi-wavelength data for subsets of our sample from other surveys. The SDSS-RM sample probes a diverse range in quasar properties and shows well-detected continuum and broad-line variability for many objects from first-season monitoring data. The compiled properties serve as the benchmark for follow-up work based on SDSS-RM data. The spectral fitting tools are made public along with this work.

We study the long-term variability in the optical monitoring database of Ark 120, a nearby radio-quiet active galactic nucleus (AGN) at a distance of 143 Mpc (z = 0.03271). We compiled the historical archival photometric and spectroscopic data since 1974 and conducted a new two-year monitoring campaign in 2015–2017, resulting in a total temporal baseline over four decades. The long-term variations in the optical continuum exhibit a wave-like pattern and the Hβ integrated flux series varies with a similar behavior. The broad Hβ profiles have asymmetric double peaks, which change strongly with time and tend to merge into a single peak during some epochs. The period in the optical continuum determined from various period-search methods is about 20 yr, and the estimated false alarm probability with null hypothesis simulations is about 1 × 10−3. The overall variations of the broad Hβ profiles also follow the same period. However, the present database only covers two cycles of the suggested period, which strongly encourages continued monitoring to track more cycles and confirm the periodicity. Nevertheless, in light of the possible periodicity and the complicated Hβ profile, Ark 120 is one candidate of the nearest radio-quiet AGNs with possible periodic variability, and it is thereby a potential candidate host for a sub-parsec supermassive black hole binary.
Breezing through the Space Environment of Barnard’s Star b

Published: April 2019

A physically realistic stellar wind model based on Alfvén wave dissipation has been used to simulate the wind from Barnard’s Star and to estimate the conditions at the location of its recently discovered planetary companion. Such models require knowledge of the stellar surface magnetic field that is currently unknown for Barnard’s Star. We circumvent this by considering the observed field distributions of three different stars that constitute admissible magnetic proxies of this object. Under these considerations, Barnard’s Star b experiences less intense wind pressure than the much more close-in planet Proxima b and the planets of the TRAPPIST-1 system. The milder wind conditions are more a result of its much greater orbital distance rather than in differences in the surface magnetic field strengths of the host stars. The dynamic pressure experienced by the planet is comparable to present-day Earth values, but it can undergo variations by factors of several during current sheet crossings in each orbit. The magnetospause standoff distance would be ∼20%–40% smaller than that of the Earth for an equivalent planetary magnetic field strength.
