An Experimental Method for Generating Shear-Free Turbulence Using Horizontal Oscillating Grids
Authors: Li Wenjie , Zhang Peng , Yang Shengfa , Fu Xuhui , Xiao Yi
Published: February 2020

An experimental apparatus driven by horizontal oscillating grids in a water tank is proposed for generating shear-free turbulence, which is measured using Particle Image Velocimetry (PIV). The performances of the proposed apparatus are investigated through the instantaneous and root-mean-square (RMS) velocity, Reynolds stress, length and time scale, frequency spectra and dissipation rate. Results indicate that the turbulence at the core region of the water tank, probably 8 cm in length, is identified to be shear-free. The main advantage of the turbulence driven by horizontal oscillating mode is that the ratios of the longitudinal turbulent intensities to the vertical values are between 1.5 and 2.0, consistent with those ratios in open-channel flows. Additionally, the range of the length scale can span the typical sizes of suspended particles in natural environments, and the dissipation rate also agrees with those found in natural environments. For convenience of experimental use, a formula is suggested to calculate the RMS flow velocity, which is linearly proportional to the product of oscillating stroke and frequency. The proposed experimental method in this study appears to be more appropriate than the traditional vertical oscillating mode for studying the fundamental mechanisms of vertical migratory behavior of suspended particles and contaminants in turbulent flows.
Nutrient Recovery from Anaerobically Treated Blackwater and Improving Its Effluent Quality through Microalgae Biomass Production

Published: February 2020

The blackwater stream of domestic wastewater contains energy and the majority of nutrients that can contribute to a circular economy. Hygienically safe and odor-free nutrient solution produced from anaerobically treated source-separated blackwater through an integrated post-treatment unit can be used as a source of liquid fertilizer. However, the high water content in the liquid fertilizer represents a storage or transportation challenge when utilized on agricultural areas, which are often situated far from the urban areas. Integration of microalgae into treated source-separated blackwater (BW) has been shown to effectively assimilate and recover phosphorus (P) and nitrogen (N) in the form of green biomass to be used as slow release biofertilizer and hence close the nutrient loop. With this objective, a lab-scale flat panel photobioreactor was used to cultivate Chlorella sorokiniana strain NIVA CHL 176 in a chemostat mode of operation. The growth of C. sorokiniana on treated source-separated blackwater as a substrate was monitored by measuring dry biomass concentration at a dilution rate of 1.38 d−1, temperature of 37 °C and pH of 7. The results indicate that the N and P recovery rates of C. sorokiniana were 99 mg N L−1d−1 and 8 mg P L−1d−1 for 10% treated BW and reached 213 mg N L−1d−1 and 35 mg P L−1d−1, respectively when using 20% treated BW as a substrate. The corresponding biomass yield on light, N and P on the 20% treated BW substrate were 0.37 g (mol photon)−1, 9.1 g g−1 and 54.1 g g−1, respectively, and up to 99% of N and P were removed from the blackwater.
Flood Routing Process and High Dam Interception of Natural Discharge from the 2018 Baige Landslide-Dammed Lake

Published: February 2020

The outburst flood of the Baige landslide dam caused tremendous damage to infrastructure, unfinished hydraulic buildings, roads, and bridges that were built or under construction along the Jinsha River. Can downstream hydraulic buildings, such as high dams with flood control and discharge function, accommodate outburst floods or generate more serious losses due to wave overtopping? In this study, the unsteady flow of a one-dimensional hydraulic calculation was used to simulate natural flood discharge. Assuming a high dam (Yebatan arch dam) is constructed downstream, the flood processes were carried out in two forms of high dam interception (complete interception, comprehensive flood control of blocking and draining). Moreover, three-dimensional visualization of the inundation area was performed. Simulation results indicate that the Yebatan Hydropower Station can completely eliminate the outburst flood risk even under the most dangerous situations. This station can reduce the flood peak and delay the peak flood arrival time. Specifically, the flood peak decreased more obviously when it was closer to the upstream area, and the flood peak arrival time was more delayed when the flood spread further downstream. In addition, the downstream water depth was reduced by approximately 10 m, and the inundation area was reduced to half of the natural discharge. This phenomenon shows that hydraulic buildings such as high dams can reduce the inundation area of downstream farmlands and extend the evacuation time for downstream residents during the flood process, thus reducing the loss of life and property.
Effect of Wastewater Irrigation on Photosynthesis, Growth, and Anatomical Features of Two Wheat Cultivars (Triticum aestivum L.)
Authors: Hajihashemi Shokoofeh , Mbarki Sonia , Skalicky Milan , Noedoost Fariba , Raeisi Marzieh , Brestic Marian
Published: February 2020

The wastewater from the Razi petrochemical complex contains high levels of salts and heavy metals. In the present research, the effects of different wastewater dilution levels (0, 25%, 50%, and 100%) were studied on two wheat cultivars—Chamran and Behrang. The wastewater contained high levels of NH4+, NO3-, PO43-, and SO42-, and Mg, Ca, K, Na, Cu, Zn, Fe, M, and Ni. The toxic levels of mineral elements in the wastewater resulted in a significant decline in the K, P, Si, and Zn content of leaves. Irrigation with the wastewater resulted in a significant reduction in photosynthetic characteristics including chlorophyll fluorescence (Fv/Fm and PIABS), intercellular CO2, net photosynthesis, water use efficiency, and photosynthetic pigments. The reduction in photosynthesis was followed by a significant decrease in the carbohydrate content and, subsequently, plant height, leaf area, and grain yield. Increasing the wastewater concentration reduced leaf thickness and root diameter, accounting for the decrease in xylem and phloem vessels, the root cortical parenchyma, and mesophyll thickness. The bulliform cell size increased under wastewater treatment, which may suggest induction of a defense system against water loss through leaf rolling. Based on the observed negative effect of wastewater on physiology, morphology, anatomy, and yield of two wheat cultivars, reusing wastewater with high levels of total suspended solids and salts for irrigation cannot be approved for wheat crops.

Masové médiá v demokracii
Authors: Duffeková Katarína
Published: February 2020

Independent mass media are an important part of democracy. Their task is to control whether democratic principles are truly fulfilled in society. Furthermore, their responsibility is to inform the public about important political and socio-political issues. Mass media provide the platform for bigger citizen participation but also for fun and education. The aim of this article is to characterize the functions of mass media in modern democracies according to two types of sources – ones from scholars which focus on the relationship between mass media and democracy and others from scholars that focus on mass media theory and relationship of mass media with percipients. By the method of analysis it was concluded that the most important function of mass media in both types of sources was to provide information. However, other functions appear in a number of publications as well, e.g., mass media as a watchdog or as a platform to exchange opinions and ideas.
Inštitucionálne zázemie mládežníckej politiky Slovenska: priestor pre europeizáciu?
Authors: Džačovský Tomáš
Published: February 2020

Youth policy of the Slovak Republic in the present is in development process of a new strategy for youth. At the national level, the policy is made by interdepartmental and interdisciplinary cooperation accommodated by the Ministry of Education, Science, Research and Sport of the Slovak Republic. In a process of policy making, the Ministry cooperates also with different actors on local and regional levels as well as on the European level. European Union develops its own youth policy in the form of Youth Strategy 2019-2027.Youth policy is, however, only a weak competence of the EU, while every country develops its own policy on the national level. Thereby it is important to focus on the level of influence of the EU through Europeanization on the Slovak youth policy, and on the question, whether there is any Europeanization during policy process at the national level at all. The aim of this work was to analyse the process of agenda-setting and policy formulation during the policy process of youth policy making under the responsibility of the Ministry and to investigate possible influence of Europeanization on this phase of a policy cycle. By using qualitative data analysis and process-tracing method we were able to find some evidence of possible Europeanization in early phases of the policy-process. On the other side, we found limitations of an EU influence on that process mainly as a result of non-binding nature of the open method of coordination.
Does the Economic Security of the Russian Speaking Minority Threaten the Latvian National Security?
Authors: Hynek Ondřej
Published: February 2020

The core of this paper is aiming at the economic security of the Russian minority in Latvia. The Russian minorities are representing the potentially vulnerable part in Baltics security because of the collapse of the USSR that led to the disputes between the Russian minority and “local” Baltics citizens. Thus, the economic conditions mean the crucial point for allaying the disputes and improving the security, therefore, the Russian minority in Latvia won’t tend to be integrated back to Russia. With this mind, the inquiry of the economic conditions of the Russian minority should depict if the economic security of the Latvian Russians jeopardizes the national security of Latvia. The paper is anchored on the concept of national security and economic security. The research is comparing and evaluating progress. Thus, the utilization of the comparative and process-tracing methods should endorse to explicate how the Latvian- Russians are doing in comparison with Latvians and evaluate progress during the time. Despite that the conditions of the Russian minority are constantly improving, we should not underestimate them since they have not reached the level of Latvians yet.

Authors: Richvalský León
Published: February 2020

The aim of our paper is to describe the legislative development and changes within the functioning of tax assignation mechanism, which was firstly implemented into Slovak legislation in 1999. It presents one form of direct financial support for non-governmental and non-profit organizations. During the twenty years it underwent many changes and challenges, but it managed to persist and annually bring elements of citizen direct decision-making into the system of representative democracy. By using it, taxpayers can redistribute certain share of their income tax to certain entities. They do not pay the full amount of the tax to the government, but redistribute a share of it to selected beneficiary. Our paper has analytical and inductive character. The method of scientific abstraction was used during the processing of theoretical knowledge about our issue, and analytical method was utilized during the data collection from multiple sources, which was essential for detailed examination of specific parts of this issue. We have used multiple legislative Acts as our main research data, as well as the transcriptions of debates in the National council of the Slovak Republic. Tax assignation has found its place in Slovak tax system, gained large popularity among taxpayers and receiving beneficiaries, and legislation concerning its functioning was frequently discussed and amended. Implementation of tax assignation mechanism was successful, and it continues to support the development of non-profit sector, which is important in every post-communist country.

Authors: Nikolaeva L.A. , Ignatieva L.P. , Savchenkov M.F.
Published: February 2020

Introduction. It has been demonstrated that the use of 2,4-D herbicide contaminates the environment with polychlorinated compounds, including dioxins. Additional risk factors for population health and the environment include climatic conditions of Siberia, processes of translocation of compounds from soil to plants, their ability to reach the human body along trophic chains and to have a toxic effect. The objective of this study was to analyze the behavior of the 2,4-D herbicide and dioxins in the environment and to justify health risk factors. Materials and methods. We used the method of gas chromatography-mass spectrometry that combines high efficiency of separation of impurities, the possibility of determining their molecular composition, selectivity of recording, and high sensitivity. We used a chromatographic method to determine residual amounts of the 2,4-dichlorophenoxyacetic acid amine salt (2,4-D) in soil, feed, and food of plant and animal origin. The calculation of average and statistical errors of indicators was performed using t-test in MS Excel. Results. Contamination of water of open reservoirs of the Irkutsk Region with the 2,4-D herbicide amine salt was found in concentrations as high as 7.7 μg/L with a positive sample count of 49%. In spring and summer, the water of open reservoirs is also polluted. In soils, the 2,4-D amine salt is immobile, concentrated in the surface layer at the level of 0.42–0.37 mg/kg. The maximum total soil concentration of dioxins reached 1,479 ng/kg exceeding the maximum permissible soil concentration of dioxins by 306 times. The maximum concentration of dioxins in feed was found at the end of the growing season (317–322 ng/kg). Dioxins accumulate in fat-containing food; thus, measured dioxin concentrations in butter averaged 680.6 ng/kg demonstrating a 10-fold excess of the permissible level. The estimated daily intake of dioxins with food can be as high as 26.2 pg/kg, which is 2.6 times higher than the permissible daily dose. We conducted the environmental and medico-hygienic analysis of outcomes of using the effective herbicide that poses a serious danger to human health due to the possibility of dioxin formation. We identified risk factors and substantiated the daily dose of dioxins for humans as a temporary value.

Published: February 2020

The article deals with the influence of factors on the formation of the resource potential of agricultural enterprises and increasing the efficiency of its use. The main obstacles to the effective functioning of the system of state support of agriculture in Ukraine are considered. It is determined that state support is an integral part of state regulation and is a combination of different tools and instruments. Preferential financing of the most vulnerable enterprises and branches of agriculture, improvement of the mechanism of state support will contribute to the development of agricultural production and will have a positive impact on the situation in rural areas. It has to be implemented taking into account the specificity of the regional situation, as well as the financial capacity of the budget. The role of the state agrarian policy in the development of rural regions is investigated and the priority direction of rural activity – diversification of agricultural production is determined. Based on the main directions of agricultural development in the region, a system model for improving the efficiency of agricultural enterprises development is proposed. A number of measures of state regulation are proposed to introduce a qualitatively effective regional economic policy through the formation of an efficient regulatory framework. Given the basic imperatives, improving of state support for the development of agricultural enterprises for the formation of their resource potential and increasing the efficiency of its use requires creating the conditions for the introduction of a qualitatively new, effective regional economic policy, stimulating the dynamic development and efficient use of the internal resource potential of each region, which requires taking into account the decisive role of the agricultural enterprise rural areas and the transition to state strategic programming in regional development and implementation of regional development strategies of local governments and local authorities. State regulation of agricultural production should be oriented on innovation and investment development of agricultural enterprises. To this end, it is necessary to amend the Law of Ukraine “On Innovative Activity”, to improve customs regulation of innovative activity and the procedure of granting the innovative status to enterprises and to foresee the possibility to carry out expertise in qualifying innovative projects at the expense of public funds.
Using Vocabulary Apps to Enhance Students’ Vocabulary Knowledge
Authors: Ludwig Christian
Published: February 2020

The fast and increasingly natural adoption of handheld devices such as smartphones and tablets into everyday life is a rapidly growing social phenomenon which is also believed to have vast potential for foreign language learning. The small-scale study presented in this article contributes to the discussion of whether handheld devices should be further integrated into or eliminated from the classroom by presenting part of the results of a small-scale study conducted in a German secondary English as a foreign language classroom. The study examined the impact of a mobile vocabulary learning app on secondary school students’ vocabulary performance, also giving some indications about the students’ development of foreign language learner autonomy. Although the results of the study showed an unexpectedly limited use of the app, they allow assumptions to be made about the reasons which prevented students from using the app more frequently which can influence future researchers’ and practitioners’ app choices. The first section of this article briefly outlines the theoretical framework of the study, particularly focussing on the potential of computer-assisted and mobile-assisted language learning for enhancing students’ foreign language skills and learner autonomy. The ensuing section then provides some background on investigating students’ foreign language vocabulary learning. This is followed by a presentation of the research design, including the main features of the app (Socrative) used in this study. The next section then critically discusses some of the major research results. The contribution concludes by summarising some of the outcomes of the study and outlining some gaps for further research.
Phenomenological Analysis into Students’ Self-Perceived Autonomy and Out-Of-Class Learning
Authors: Mideros Diego
Published: February 2020

Autonomy researchers have employed qualitative approaches to investigate a variety of issues. Ethnographies, case studies, language learning histories, (auto)biographies, among others, are featured in the literature. Some of these approaches fall under the umbrella of narrative research (Barkhuizen, Benson, & Chik, 2014; Early & Norton, 2012), which is emerging strongly in the L2 learning research (Barkhuizen, 2013; Benson 2014). This paper discusses another approach that has not been widely featured in autonomy or L2 learning research, phenomenology. “Phenomenology is a philosophical approach to the study of experience” (Smith, Flowers, & Larkin, 2009, p. 11). Phenomenology seeks “to determine what an experience means for the persons who have had the experience and are able to provide a comprehensive description of it” (Moustakas, 1994, p. 13). Phenomenological research was employed to explore the phenomenon of ‘institutionalised L2 learning and possibilities for autonomy in Trinidad & Tobago’ with thirty students in the context of a BA in Spanish programme. Students’ self-perceived autonomy emerged from the analysis and shed light on the sociocultural phenomena that enabled or hindered students’ development and exercise of autonomy. The paper illustrates how phenomenological research can be a valuable qualitative approach to explore sociocultural phenomena in learner autonomy.
Becoming a Language Learning Advisor: Insights From a Training Program in Brazil
Authors: Walkyria Magno e Silva , Castro Eduardo
Published: February 2020

Advising in language learning is a relatively new field in applied linguistics that has attracted a great deal of attention recently as a result of its focus on individual language learning trajectories. It is an effective way of fostering learner autonomy, motivation and self-regulation as it encourages reflection on the language learning process. In this regard, proper training must be provided for language learning advisors. This paper briefly describes a training program conducted with fourteen pre-service language advisors at a university in northern Brazil. Using a focus group interview and an open questionnaire, the authors explore its effects on those who participated in that training program, by reporting on participants’ initial advising trajectories. Implications for future training is discussed.
Longitudinal Trajectories of Emotions in Four Dimensions Through Language Advisory Sessions
Authors: Moriya Ryo
Published: February 2020

Through advising in language learning, this study describes two Japanese secondary school students’ (Ai and Yu: both pseudonyms) longitudinal trajectories of socioculturally mediated emotions in four dimensions. To investigate types of emotions, the research integrates multiple qualitative methods and Plutchik’s wheel of emotions, thus acknowledging both contextually complex and longitudinally dynamic aspects of emotions. Throughout a year of 19 advisory sessions, the amount of time spent was 1,263 minutes (Ai’s 12 sessions = 891 minutes; Yu’s 7 sessions = 372 minutes), and the number of emotional incidences identified was 358 (201 for Ai; 157 for Yu). Among multiple findings, the most notable was that both participants experienced convergence of emotions: the one process from diversified to less diversified emotions was caused by longitudinal dynamics of emotions in Ai’s case and by contextual complexity of emotions in Yu’s case. The study concludes by suggesting a tentative four-dimensional model of emotions to capture trajectories of advisees’ emotions from multiple perspectives. This model can help advisors to understand advisees’ emotionality and, therefore, to implement emotional support appropriately and continuously.

Checking elevation differences due to deflection on the railroad (skilu) is needed to ensure the safety of train travel. Skilu measurements can be done with a measuring train and a manual densometer. For manual measurement, we need tools that can measure dynamic elections more accurately and efficiently. This research is intended to make these tools using ultrasonic proximity sensors with data processing by a microcontroller. The measurement accuracy of the experimental results of this tool is obtained by comparing the densometer deflection gauge. The results show that the tool can measure elections every 0.1 second (realtime) with an accuracy rate of 98.84%. In addition to the election measurements, this tool can also measure the speed of a passing train and the rail temperature when a train passes. The measurement results can help optimize the care needed for the election that occurs at the observation site.

Railway travel safety is an important component in rail transportation. The reliability of the railroad infrastructure is one of the points to support the safety of railroad operations. Lintas Bandung - Cikampek is a cross that has varied geographical contours where right-left rail roads have hills and slopes so that the area between Purwakarta Station - Ciganea Station is a landslide-prone area. As happened in the field there was an avalanche at KM 107 + 100 - KM 107 + 300 which caused disruption to train travel. In addition, improper handling of landslides will cause other potential dangers. The handling of the landslide slope in KM 107 + 100 - KM 107 + 300 uses steel tape from the used rails because the landslide is considered to be less than optimal and is looking for other ways to handle landslides. looking for comparisons compared to using the shotcret method. In this study, we tested the landslide handlers that have been carried out by comparing the handling carried out in accordance with the existing provisions between the steel plaster method of the rail used with the shotcrete method. The cause of landslides is due to a steep angle of 65⁰ with a peak height of 15 meters. The impact on crossing is applied to taspat 5 km / hour to anticipate sudden landslides. From the results of the analysis, it was found that the shotcrete method was considered capable of handling landslide-prone areas in KM 107 + 100 - KM 107 + 300. However, for the handling that had been carried out using steel plaster from used rails. However, this handling is considered not optimal because of the limited number of rails around vulnerable areas, resulting in plaster walls that can still make material exit to the railroad tracks.

Service and convenience are important factors in carrying out modes of transportation, especially railways. As the development of railways in Indonesia is needed in terms of service and comfort. It often happens that passengers who miss the destination station are still problems that must be resolved in the service and comfort of the train facilities. Early warning systems that are still universal using speakers still lack maximum service. From the results of a survey conducted there are still many potential passengers who are worried about being missed by the destination station. In this research, a prototype of an early warning system with a vibrator mounted on the train seat was made when a passenger arrived at the destination station. This tool is able to provide early warning individually, so that people who will arrive at the destination station are not missed. This prototype works using the Arduino Uno Atmega328 microcontroller as its control system. Vibration machine with 53 Hz of vibration. After testing 43 respondents, the average person woke up after being given a vibration of 53 Hz is 4 seconds. Keypad as data input for destination destination code. The light if the passenger is not awakened turns on for 5 minutes. The results of this study are able to help the early warning system work through speakers more leverage
