Full textAbstract:
Clean water is an essential basic requirement for humans. In eastern Indonesia, especially the provinces of East Nusa Tenggara (NTT), Maluku and Southeast Sulawesi, the need for clean water is quite urgent. The socio-cultural conditions, geographical conditions, low rainfall levels, and the distribution of freshwater from the Regional Water Company (PDAM) is still not right. Communities in the three provinces utilise clean water buying and selling services using tank cars to fulfil their daily needs for clean water in reservoirs and water tanks. Orders still use telephone or SMS, so it seems slower. Thus the design of mobile ordering applications for clean water was proposed in this study and was named Go-Water. With the Go-Water app, users can order clean water by choosing the closest shelter model and driver, and then the order is forwarded to the driver for processing. The User-Centered Design (UCD) method use for Go-Water application design. The Go-Water application can help users to order clean water quickly and help improve business quality for service providers. The results of the usability perspective analysis on the Go-Water application design obtained an average percentage of 83%. The result shows the design of the Go-Water app, can be accepted according to user needs. The contribution in this study is the design of the proposed mobile application centred on the user, previously there was no system for ordering 5,000 litres and 6,000 litres of clean water using a tank car and the price offered was more beneficial for both parties.

Full textAbstract:
Iodine-131 (I-131) mostly used in nuclear medicine for radioiodine ablation (RAI) therapy and hyperthyroid treatment. Patient was orally ingested I-131 and warded within 3 to 4 days for RAI therapy, whereas outpatient for hyperthyroid treatment. Radioactive waste from patient’s body such as urine and feces were eliminated from the ward into delay tank. Delay tank is an underground system to reduce radioactivity of contaminated I-131 clinical waste water at certain level before will be discharged into ordinary sewage system. Delay tank indirectly restricted the number of patient admission due to its periodical clearance and small volume size. Thus, a new technique to extract I-131 radionuclide with contaminated mixtures in solid form from the delay tank has been proposed as an alternative for clinical waste water management in nuclear medicine. Radioactive clinical waste water samples from delay tank were mixed with Graphene Oxide (GO) with varies in concentrations before filtered using micro pore filter paper. After 15 – 30 minutes, the radioactivity of the water residue left beneath the filter paper were counted using well counter. The measurements were repeated on fourth, eighth, twelfth and sixteenth days, which is significant to the natural decay of I-131 radionuclide. The water residue radioactivity decreases over the concentration of GO throughout the experiment. The mixtures of GO:I-131 (sediment formed on the filter paper) were analyzed using Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-rays (EDX) for morphology and elemental analysis. FESEM image revealed the maximum GO concentration produced high agglomeration morphology. EDX shows I-131 and other elements were attracted to GO layered sheets. The results showed that the GO had high sorption capacities in the removal of radionuclides, which was attributed to the large number of oxygen-containing functional groups on the surface or edge sites.

Full textAbstract:
The article discusses the latest issue of Go to think tank ranking and MGIMO position in it. It also considers global trends related to changes in the environment and forms of activities of research centers, identified by the ranking. In particular, it notes the changes in the system of financing think tanks from the few large grants for an extended period of time to a small but numerous grants for short periods for specific projects. It also notes the increasing state pressure on think tanks from around the world. In addition, it points to increased competition on the market of ideas and scientific expertise. Research centers have to adapt to these changes. In view of these trends the experience of one of the research centers of MGIMO, the Center for Military-Political Studies is considered. Innovation activities of the Centre on a whole corresponds to global trends. The center is seeking to diversify its sources of funding and enhances the focus of research topics - long-term forecasting of the international military and political relations.

Full textAbstract:
Modern digital cameras are increasing in quality whilst decreasing in size. In the last decade, a number of waterproof consumer digital cameras (action cameras) have become available, which often cost less than $500. A possible application of such action cameras is in the field of Underwater Photogrammetry. Especially with respect to the fact that with the change of the medium to below water can in turn counteract the distortions present. The goal of this paper is to investigate the suitability of such action cameras for underwater photogrammetric applications focusing on the stability of the camera and the accuracy of the derived coordinates for possible photogrammetric applications. For this paper a series of image sequences was capture in a water tank. A calibration frame was placed in the water tank allowing the calibration of the camera and the validation of the measurements using check points. The accuracy assessment covered three test sets operating three GoPro sports cameras of the same model (Hero 3 black). The test set included the handling of the camera in a controlled manner where the camera was only dunked into the water tank using 7MP and 12MP resolution and a rough handling where the camera was shaken as well as being removed from the waterproof case using 12MP resolution. The tests showed that the camera stability was given with a maximum standard deviation of the camera constant σc of 0.0031mm for 7MB (for an average c of 2.720mm) and 0.0072 mm for 12MB (for an average c of 3.642mm). The residual test of the check points gave for the 7MB test series the largest rms value with only 0.450mm and the largest maximal residual of only 2.5 mm. For the 12MB test series the maximum rms value is 0. 653mm.

Abstract. In past decades theoretical studies have been carried out with the double aim of improving the knowledge of rogue wave main characteristics and of attempting to predict its sudden appearance. As an effort on this topic we tried the generation of rogue waves in a water wave tank using a symmetric spectrum (Akhmediev et al., 2011a) as input on the wave maker. To go on further the next step has been to apply a theoretical model to the envelope of these waves. After some considerations the best model has been an analogue of the Ginzburg–Landau equation.

Full textAbstract:
Cormorants hunt both benthic (sedentary) and pelagic (motile) prey but it is not known if the energy costs of foraging on these prey differ. We used respirometry to measure the costs of diving in double-crested cormorants ( Phalacrocorax auritus ) foraging either for sedentary (fish pieces) or motile (juvenile salmon) prey in a deep dive tank. Short dives for sedentary prey were more expensive than dives of similar duration for motile prey (e.g. 20% higher for a 10 s dive) whereas the reverse was true for long dives (i.e. long dives for motile prey were more expensive than for sedentary prey). Across dives of all durations, the foraging phase of the dive was more expensive when the birds hunted motile prey, presumably due to pursuit costs. The period of descent in all the dives undertaken appears to have been more expensive when the birds foraged on sedentary prey, probably due to a higher swimming speed during this period.

Efforts to reduce the impact of waste improvement on degradation of water quality can be transferred by utilization of inorganic waste as a source of seaweed nutrition. This study aimed to determine the growth and protein content of Ulva prolifera maintained at different flow rates in integrated aquaculture system. 9 Yellowtail stocked with 5.095 g with an average weight of 566.11±81.51 g were kept in 540 L tank for 24 days, by water flowing at the rate of 10 L min-1. Water from the fish tank was distributed into the sediment tank and go to 6 Ulva tanks with the flow rate of 0.5, 1.0 and 1.5 L min-1. Test parameters measured were growth performance of Yellowtail, biomass of Ulva prolifera, protein content of Ulva prolifera, and total ammonia nitrogen. The measurement results showed that the biomass of fish increased to 5.408 g, then biomass of Ulva increased to 42 g, 156 g and 155 g for flow rate of 0.5 L, 1 L and 1.5 L min-1, respectively. The protein content of Ulva for all the treatments was the same (P> 0.05). A total of ammonia in the tank outlet of Ulva (0.0202 - 0.1137 mg N L-1) were smaller than those were in the inlet (0.0286 - 0.1394 mg N L-1).

Full textAbstract:
Unsteady flow of a single six-blade ruston turbine in stirred tank is numerically simulated by using the large eddy simulation. Then the effect of the turbine installation position on mixing flow field is studied. The result shows that with a relatively low paddle installation position, mixing effect at the bottom of tank is obvious, while which go against the materials at the top layer mixing. When the paddle is installed at the top of the stirred tank, liquid splash and a concave downward liquid surface are easily caused. Finally the cavitation phenomenon is generated. When the paddle is installed from 1/3H to 2/3H, there are a uniform flow field distribution and higher average velocity flow. Large size vortex structures at the top and the bottom of the paddle are obvious which is beneficial to mix the materials.

Full textAbstract:
ABSTRACT In early February 1986 the U.S. tank barge St. Thomas struck a submerged object in Charlotte Amalie harbor, St. Thomas, U.S. Virgin Islands. Damage to the barge's number 1 starboard cargo tank resulted in the loss of an estimated 500 barrels of No. 6 fuel oil. Later, an additional 100 barrels were lost when temporary patching of the tank let go. These two spills are believed to be the largest that have affected the U.S. Virgin Islands. When the operators of the barge failed to initiate an appropriate response to remove the oil, the Coast Guard on-scene coordinator initiated a federal response under the authority of the Federal Water Pollution Control Act. Over the next month the OSC coordinated the cleanup of this oil which had pocketed around the harbor. Total costs for the cleanup exceeded $1.9 million. No long-term environmental damage is believed to have occurred.

IJEEIT International Journal of Electrical Engineering and Information Technology 4, no. 1 (2021): 47–55. http://dx.doi.org/10.29138/ijeeit.v4i1.1282.
Full textAbstract:
Commonly most of the houses rely upon the overhead and underground tanks as the main source of water. People usually turn on the motor when their taps go dry and switch off the motor when the tank starts overflowing. This results in needless wasting of water and the lack of water in emergencies. This water is mostly coming through supply line pipes installed by the government through different schemes. The timing of this water coming is mostly irregular because it varies time to time, and in areas where it is fixed, the time is inconvenient for domestic residents to switch ON their motors and fill their tanks. Either the water comes late at night or in the daytime when the people are mostly at their jobs, so they are unable to turn ON their motors. This paper presents a solution to both these problems, a hardware model has been developed using Arduino as the main microcontroller, ultrasonic sensors to detect the level of water in tanks two pumping motors one for underground and one for an overhead tank. And one a water flow sensor is used to automatically detect the water coming in supply lines and switch on the motor. The proposed system saves water, electrical power and human efforts as the whole system is automatic.

Full textAbstract:
Think tanks, or policy advice institutions, are civil society organizations producing and delivering social analysis to policymakers and the wider public. Their aim is to influence policy in a given direction. Compared to most other civil society organizations, they hold relatively privileged positions, both in terms of wealth (on average bigger budgets and staffs), political influence (their very raison d’être), knowledge (educational level of the staff), and social networks. Thus, it seems beyond dispute that think tanks adhere to the elite of civil society. This article focuses on think tanks’ negative self-identification, on their reluctance to accept labels. Not only are think tanks unwilling to take on the elite designation, some of them also deny being part of civil society, and some go one step further in denying identification with the think tank community. These multiple denials are expected if we recall Pierre Bourdieu’s observation that “all aristocracies define themselves as being beyond all definition” (Bourdieu, 1996, p. 316). The analysis focuses on how this definitional ambiguity is discursively constructed. Think-tankers are often described as situated in an interstitial space between such fields as politics, civil society, media, market, and academia. While this intermediary position is the source of their unique role as converters of various forms of capital, it also complicates the identity formation of think tanks. The argument is illustrated by Polish think tanks and the data consists of original interviews with think tank leaders. The article provides a novel perspective on think tanks and on civil society elites.

Full textAbstract:
ABSTRACT Since the enactment of the Oil Pollution Act of 1990 (“OPA 90”) more than 10 years ago, many states took aggressive action regulating the marine industry. States, sometimes stepping well beyond their bounds, enacted comprehensive oil pollution laws that imposed additional liability, as well as prevention and response planning requirements, beyond those contained in OPA 90. Washington State was clearly the most aggressive when it implemented its Best Achievable Protection (BAP) regulations in the early 1990s. The International Association of Independent Tanker Owners (Intertanko) challenged the BAP regulations, and the Supreme Court sided with Intertanko and reaffirmed that states may not regulate vessel construction, design, operation, and manning. States, however, have not given up the gauntlet and continue to aggressively regulate the marine industry by expanding their regulation beyond tank vessels to include passenger vessels, cargo vessels, and tugs/barges. This paper will review newly enacted laws and regulations, including financial responsibility, response/contingency plans, drills and exercises, ballast water, vessel inspection programs, and implications associated with discharges from cruise vessels. The paper will conclude by identifying potential trends for the future.

Full textAbstract:
Despite competing for resources such as space, food and mates, many territorial animals are less aggressive towards neighbours who rarely go beyond their territorial boundaries. This so-called dear enemy phenomenon is advantageous in territorial defence, but it has not been well studied in fish. In this work, we tested the ‘correct–incorrect boundary paradigm’ of the dear enemy phenomenon using the territorial cichlid fishNeolamprologus pulcher, which exhibits dear enemy relationships. When the fish was placed in a small experimental tank, in which fish established its territory, it was initially very aggressive against a neighbouring fish in an adjacent tank, but the aggression level decreased rapidly (within 4 days). When the tank containing the neighbour was shifted to the opposite side, the focal fish was more aggressive than the day before, but it exhibited less aggression than it did against a stranger placed on the shifted side. This lower level of aggression suggested that the focal fish did not regard the shifted neighbour as a stranger. Our observations provide support for the threat-level hypothesis, according to which territory owners will modulate aggression intensity based on the threat level.

 1 RESUMO
 
 Objetivou-se com este trabalho realizar a análise de custo e desempenho agronômico da alface crespa produzida em ambiente protegido submetida a diferentes níveis de irrigação e diferentes doses de solução hidroretentora. O trabalho foi realizado na área experimental do Instituto Federal Goiano - Campus Urutaí-GO, cujas coordenadas geográficas são latitude 17º29’10” S, longitude 48º12’38” O e altitude de 697 m, no período de dezembro de 2017 a janeiro de 2018. O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial (4x5), com parcela subdividida e quatro blocos, em que se utilizaram quatro níveis de irrigação (50, 75, 100 e 125%) da evaporação obtida diariamente, junto ao tanque Classe A e cinco doses de solução de hidrogel (0, 50, 100, 150 e 200 g). Analisou-se o custo de produção considerando os gastos efetivos realizados durante o ciclo produtivo além das variáveis produtividade (PRO) e a eficiência do uso da água (EUA). Os níveis de irrigação e doses de solução hidrorretentora utilizados influenciaram significativamente as variáveis PRO e EUA. A lucratividade cresceu com o aumento das lâminas de irrigação e decresceu com a utilização do hidrogel.

After this tragic accident of Colombia's shuttle the continuance of these spatial functions were encountered with ambiguity and lots of suspicion was formed in the NASA officer's brain. The burst was formed because of the defect which was made in the outer insulator fuel tank, a insignificant piece of insulator that was separated while throwing the Colombia's shuttle from the fuel tank under the aerodynamical force of throw (while separating the tank from the shuttle) and it hurts the ledge of the left wing of the shuttle in the place of ceramics insulator defect and shuttle's thermal safety system. It was happened in throwing the shuttle discovery too, however they relief the damaged parts through a spatial marcher in the space and they turn it to the earth with so much presentiment. In this essay we present a new design for the fuel tank and shuttle. In this model, shuttle is set on the top of the fuel tank and while separating the tank from the shuttle, the probable separating pieces, wouldn't be defect to the shuttle. In this procedure because the tank has a motor, a cart landing and a control system, it is again useful and would make the economy in the charges. In this Method by putting shuttle on top of the tank, it may not make any hurt to the thermal shield and there weren't any accident accession like the Colombia's shuttle accident and There wouldn't be any requirement to design a new space crafts with the passenger to go and return, and according the heavy costs of the researches, temptation and long time providence it would be much and According to probability of returning the fuel tank to the earth, in other throwing there would be multiple providence that can be a justification for this project And also Changing the tank place improves the aerodynamical coefficient in comparison present shuttle's picture that will cause to reduce using the fuel.

On 6th and 7th February 2018, a Think Tank took place in Ljubljana, Slovenia. It was a follow-up of the “Big Data Training School for Life Sciences” held in Uppsala, Sweden, in September 2017. The focus was on identifying topics of interest and optimising the programme for a forthcoming “Advanced” Big Data Training School for Life Science, that we hope is again supported by the COST Action CHARME (Harmonising standardisation strategies to increase efficiency and competitiveness of European life-science research - CA15110). The Think Tank aimed to go into details of several topics that were - to a degree - covered by the former training school. Likewise, discussions embraced the recent experience of the attendees in light of the new knowledge obtained by the first edition of the training school and how it comes from the perspective of their current and upcoming work. The 2018 training school should strive for and further facilitate optimised applications of Big Data technologies in life sciences. The attendees of this hackathon entirely organised this workshop.

The Thamirabarani River is one of the prominent sources of water for Kadamba Tank. Thamirabarani river is the perennial river in the South Tamil Nadu. Apart from that, which can store water during the North-East Monsoon period. The water user association members are getting money from duck rears and allowing duck into the agriculture fields after the harvest. The agriculturist is saying that after the first harvest if the water is not sufficient for the next crop such as paddy, farmers can go for the crop such as zero water consumption crops like green gram, black gram. Because of duck farming, agriculturists are not able to get benefited from low-cost crops. Indeed, water is the scarcity of resources in Tamil Nadu; irrigation water should not be charged more. Like other places in Tamil Nadu, in Kadamba Kulam agriculture basin, also collecting charges (ayakatu) for water usage by the association. The nonavailability of water throughout the year, the agricultural labors are moved from native and employed in the industrial sector. Tamil Nadu is a water tense state that lingers to experience water shortages which are expected to exacerbate in future due to the political pressure and money laundering, Justices A. Selvam and P. Kalaiyarasan dismissed the petitions on several grounds, including the State government’s submission that only 43 mc ft out of 5,049 mcf of surface water that goes waste into the sea was being supplied to the two industries. The court said that such supply did not affect either irrigation or drinking water needs of the people in any way.

Full textAbstract:
An information society sets new vectors for the development of all socio-political and socio-economic institutions. The efficiency and professionalism with which these institutions implement communication technologies into their practices and adapt to challenges of the modern world determine its potential and further development. This article examines the operation of such a socio-political institution as a “think tank”, given conditions of the internet’s ever growing importance and the expansion of social media. Traditionally “think tanks”, or “analytical centers”, are considered by political experts and specialists in international affairs to be components of political systems, however, the expansion and development of such organizations all around the world, together with their increasing functional capacity, leads to the need for interpreting the place and role in society of such think tanks from a sociological standpoint. This article examines them as a socio-political institution, which simultaneously generates and conveys information which is of importance to both the government and society. The main function of such an institution is designated as “communicative”, which encompasses the social potential of think tanks as a crucial component to developing social awareness and democracy. In order to evaluate the operation of Russia’s analytical centers, the author refers to the “Global Go To Think Tank Index” global ranking. Russian analytical centers are generally held in high regard by foreign experts, despite them possessing a few peculiar traits. Most of these Russian think tanks are affiliated with branches of the government, or exist within scientific institutions under the Russian Academy of Sciences or certain higher educational facilities, while being funded by the government. Their scope of research-analytical activity primarily includes issues such as foreign policy, international affairs, and global economy. As for sociological analysis of the processes occurring within society, only fragments of the former are present in the agenda of Russian think tanks. Analytical centers have an inconsequential presence in media space. They barely use modern communication technologies, which affects the isolation of the expert community from society.

Veerkamp et al. (1998) make the case for including somatic cell count (SCC) in the index of total economic merit (ITEM, Veerkamp et al., 1995) used to rank dairy bulls and cows in the UK for breeding purposes. They go on to describe an empirical method to obtain a suitable economic value for SCC, reflecting the milk quality payment scheme. Since this work was carried out, the milk price has fallen while price penalties against SCC have risen. Bulk-tank SCC (BTSCC) has fallen in response. Some of this improvement may be due to culling cows with high cell counts. The objective of this work was therefore to establish an economic value for somatic cell counts which reflected the milk quality payment scheme and took into account culling strategy.

This paper deals with the analysis and design of the optimal robust controller for the fuzzy parametric uncertain system. An LTI system in which coefficients depends on parameters described by a fuzzy function is called as fuzzy parametric uncertain system. By optimal control design, we get control law and feedback gain matrix which can stabilize the system. The robust controller design is a difficult task so we go for the optimal control approach. The system can be converted into state space controllable canonical form with the α-cut property fuzzy. For optimal control design, we find control law and get the feedback gain matrix which can stabilize the system and optimizes the cost function. Stability analysis is done by using the Kharitonov theorem and Lyapunov-Popov method. The proposed method applied to a response of Continuous Stirred Tank Reactor (CSTR).

Full textAbstract:
The use of flow predictions and on-line nutrient sensors in BNR plants has given the basis for introduction of radical operational changes. Because of the detailed monitoring, the control actions are allowed to go closer to critical process limits while balancing between hydraulic and biological capacities. One of the new modes of operation, settling in the aeration tanks as an active control, is documented below. This new operation, Aeration Tank Settling (ATS) has been tested at full scale and shows a great potential for storm water control. With ATS control the hydraulic capacity is increased 25–75% on existing plants without reducing the organic capacity in periods ranging from 2 hours to 2 weeks. ATS control can be initiated directly by raising the inlet flow to the treatment plant, but even better by 1/2 - 1 hour prediction of the inlet flow. These predictions of flow are achieved from statistical grey-box handling of data from on-line rain gauges and measured inlet flow pattern during normal and stormwater conditions. Hourly predictions of concentrations in the inlet to the plant and selected points in the sewer system during dry weather and storm situations will improve the combined system control efficiency radically.

Advanced monitoring system and preventive maintenance introduced on serviced transformer successfully reducing the equipment malfunction and breakdown rate. However, faults that occur and developed inside the transformer can be very unpredictable. One of the measures can be taken is to analyse the hottest spot temperature (HST) of the transformer, because high temperature will affect transformer insulation system performance and its life-span. HST distribution study on the transformer surface body can give better understanding on how HST will behave at inner and outer transformer surface tank, so that it can be correlated to the actual temperature inside the transformer. Therefore, this paper presents a simulation study on 100 KVA ONAN oil-filled type of distribution transformer with three types of HST intensity. Result shows that temperature distribution projectile is tending to go upwards in the insulation oil and inward into the winding. Moreover, location of HST can be identified by comparing the temperature distribution plot with and without HST.

Full textAbstract:
Abstract Turbidity currents and contour currents are common sedimentary and oceanographic processes in deep-marine settings that affect continental margins worldwide. Their simultaneous interaction can form asymmetric and unidirectionally migrating channels, which can lead to opposite interpretations of paleocontour current direction: channels migrating against the contour current or in the direction of the contour current. In this study, we performed three-dimensional flume-tank experiments of the synchronous interaction between contour currents and turbidity currents to understand the effect of these combined currents on channel architecture and evolution. Our results show that contour currents with a velocity of 10–19 cm s−1 can substantially deflect the direction of turbidity currents with a maximum velocity of 76–96 cm s−1, and modify the channel-levee system architecture. A lateral and nearly stationary front formed on the levee located upstream of the contour current, reduced overspill and thus restrained the development of a levee on this side of the channel. Sediment was preferentially carried out of the channel at the flank located downstream of the contour current. An increase in contour-current velocity resulted in an increase in channel-levee asymmetry, with the development of a wider levee and more abundant bedforms downstream of the contour current. This asymmetric deposition along the channel suggests that the direction of long-term migration of the channel form should go against the direction of the contour current due to levee growth downstream of the contour current, in agreement with one of the previously proposed conceptual models.

Full textAbstract:
The device of flexitanks, as well as technical and technological features of the transportation of goods with their use, are considered. The relevance of the topic is due to the fact that at present almost 80 % of international transit in the world takes place in containers, on the domestic markets of the largest countries of the world, goods flows also go mainly in containers. Flexitanks are studied as innovative tools for organizing the chains of delivery of goods and goods in containers, having all the necessary equipment for transporting various kinds of cargo.Analytical and marketing methods are applied, taking into account the principles of the theory of logistics, logic, as well as shared materials.A comparison of this type of packaging with other transportation means is presented. It was revealed that flexitara is more oriented to non-hazardous liquid cargo in terms of its characteristics. The use of flexitanks allows to reduce transportation costs, reduce labor, time and transportation costs, as well as to carry out multimodal transportation using various modes of transport.It is established that flexitanks can act as a full-fledged and multi-functional alternative to tanks, tank containers and other containers for transporting bulk materials that are non-hazardous cargoes. The use of technology for the transportation of goods in flexitanks will contribute to the further innovative development of multi-modal freight transportation and the growth of containerization of goods exchange in general.

Full textAbstract:
The article reveals the characteristics of think tanks as actors of the interest group politics in the European Union (EU). In this policy, they inspire public debate, conduct research, encourage new legislation and more effective public administration. A large number of European think tanks is engaged in interest group politics both at the national and supranational level of the EU governance, encouraging integration processes among the EU countries and Europeanization, which is the subject of analysis of this study. The strengthening of the role and importance of interest groups in EU policy is largely due to the increased power of the Unions institutions, since the introduction of new legislation and regulation common to all EU countries leads to the feedback from various groups that represent both public and private interests. Obviously, these groups, when interacting with the power institutions of the EU, strive for the most effective protection of their interests. For this purpose their representatives hold meetings with officials of the European Commission and the European Parliament, as well as other structures of the Union. This interaction, aiming at promoting their interests by means of lobbying and advocacy, has been regulated since 2011 by the Transparency Register, jointly created by the European Commission and the European Parliament. The purpose of this study is to analyze the quantitative performance of think tanks in the EU and to develop on its basis the Ranking of EU countries, according to the level of Europeanization of the think tanks representing them. From the research methods perspective, the study is based on the matching of statistical data from the Transparency Register and the Global Go To Think Tank Index, which serves the basis for this Ranking. The study of the ranking makes it possible to identify groups of countries with a high, medium and low level of Europeanization of think tanks in all EU countries as of January 31, 2019. The results revealed on the basis of the analysis demonstrate the heterogeneous nature of the Europeanization process of think tanks in different EU countries.

Growing NH4+ content of groundwater results in increasing exchangeable and fixed ammonium ion content of the soil. NH4+ bond in the soil may go again into solution parallel with the dilution of the soil solution but at a slower rate than fixing. This process influences significantly the NH4+ content of the soil. In settlements with no sewerage system the high NH4+ content of sewage flowing out of uninsulated septic tanks may increase the fixed NH4-N content of the soil that could have a significant effect on the quality of groundwater even after the potential disappearance of pollution sources.In this study the effects of the fixed NH4-N content of the soil around an uninsulated residential septic tank on the purification processes of the groundwater were investigated. The septic tank in the study area was dismantled in 2014 after 27 years of operation as a sewerage system was constructed. When the tank was still in operation in 2012 and 2013, very high, 55–75 mg l-1 NH4+ content was measured in the water of the monitoring well 1 metre from the tank in the course of seasonal sampling. When sewage outflow was terminated in 2014 concentrations decreased right away but even 5 years after pollutant supply was stopped, concentrations (35–57 mg l-1) highly exceeding the pollution limit (0.5 mg l-1) were measured. Considering this very high concentration, it can be assumed that great amount of NH4+ is still released into the groundwater.In order to prove this, the exchangeable and fixed NH4-N and NO3-N contents of the soil were determined by 20 cm down to a depth of 4 metres (2019). The measurements indicated the significant accumulation of exchangeable and fixed NH4-N in the zone between 220 and 400 cm. Highest fixed NH4-N concentrations of 457 mg l-1 were found between 220 and 240 cm suggesting that sewage outflow was most intense at this depth. Slow decrease in concentrations can be observed in deeper zones but concentrations higher than 350 mg l-1 were measured between 220 and 380 cm. Based on correlation analyses, the quantity of fixed NH4-N shows no correlation with the soil texture thus it can be stated that the vertical pattern of NH4-N content is determined dominantly by sewage outflow and its depth. In the unsaturated zone of the borehole a significant accumulation of NO3-N was also identified. The maximum of NO3-N was found in the zone between 100 and 140 cm. The peak nitrate calculated for NO3- ion with a value >1300 mg kg-1 is 2.5 times the limit set for the nitrate content of the geological medium.Based on the results, exchangeable and fixed NH4-N contents in the soil are still very high, 5 years after sewage outflow was stopped. The continuous solution of this component still contributes to the high NH4+ content of the groundwater. As a result, the contaminated soil in the immediate environment of the septic tank is still a pollution source.

This paper uses orthogonal experiment for optimizing technological conditions of decolorization, and draws the conclusion that the best combination is A3C3B1E1D3, namely H2SO4：1.5%；HCl：5% and sepiolite: 1.5 g/l; speed 100 r/min; time: 1.5 h. Membrane distillation technology replaces the dryer to enrich the glutamic acid neutralizer, and improves the concentration of sodium glutamate in the glutamic acid neutralizer. The membrane distillation flux of glutamic acid neutralizer changes along the concentration multiple curve. It shows that with concentration up to 60%，the glutamic acid neutralizer will supersaturate when crystal comes up and the membrane distillation can't go on. The color and conductivity of product water suggest that some volatile substances are formed. Peak time difference between glutamate filtrate gas chromatography and product water of the membrane distillated glutamic acid neutralizer does not exceed 0.1min, and thus indicates that four volatile substances from product water are derived from glutamic acid filtrate. Product water can be recollected to glutamic acid ferment tank and recycled. Scanned by FT-IR, the main ingredients in the neutralizer indicate the existence of amino acid kind materials. When replacing dryer with membrane distillation process in industrialization, glutamic acid neutralizer can be concentrated from 50% to 59%, thus greatly improves economic benefit.

<span>The paper explains utilization of Arduino Microcontroller to automatically control level of water in a tank. From a well spelt out algorithms, flowchart was drawn, from which Codes were written and compiled on Arduino IDE. IF statements were copiously used. Proteus was used to simulate the design while the project was implemented on breadboard. Liquid Crystal Display function displays the level of water on the 16 × 2 LCD thus: Very Low, Low, High and Very High. An option of I2C LCD codes was written thus providing advantage of using only two analog input A4 and A5 pins instead of 4 to 8 pins in other configurations thereby allowing other pins dedicated for other tasks. The design recommends improvements in the area of sump control so that its low water level could disable pump thus preventing it from running dry. Protection devices like circuit breaker overload and phase failure relays are recommended in order to prolong the life of the Water pump. It is believed that the design will go in long way in educating power electronic engineers in the arts of design using Arduino; also, a mass production of the device will accentuate Small and Medium Enterprises SMEs in developing countries with its concomitant economic advantages.</span>

Full textAbstract:
A recent series of academic studies, think-tank reports, and news articles shows widespread attention to rising industrial concentration and market power in the U.S. economy. In this paper, we focus on concentration in the U.S. nonfinancial corporate sector to make three contributions to the literature. First, we use examples from the debate on industrial concentration to show that there are often-divergent predictions in the theoretical literature surrounding the expected consequences of concentration and monopolization for nonfinancial firms. Second, we use industry-level concentration data to describe recent trends in average concentration. We show that, while concentration increases across the majority of industries after the late 1990s, the retail and information-services sectors are particularly key for understanding recent trends in average industrial concentration. Third, we link our industry-level analysis with firm-level data to describe the relationship between industrial concentration and nonfinancial corporations’ profitability, markups, and investment. Consistent with the ambiguities in the theoretical literature, we find that these relationships are not uniform: while some highly concentrated industries confirm standard expectations with high markups, high profitability, and low investment rates, other highly concentrated industries earn lower-than-average markups and profits, suggesting that – in some industries – increased concentration and intensified competition may go hand in hand.

Full textAbstract:
The biological phosphorus removal process is often implemented at plants by the construction of an anaerobic bio-p tank in front of the traditional N removing plant configuration. However, biological phosphorus removal is also observed in plant configurations constructed only for nitrogen removal and simultaneous or post-precipitation. The operational experience with this “accidental” biological phosphorus removal is often mixed with quite a lot of frustration, as the process seems to come and go and hence behaves quite uncontrollably. The aim of this work is to develop ways of intentionally exploiting the biological phosphorus process by the use of instrumentation, control and automation to reduce the consumption of precipitants. Means to this end are first to calibrate a modified ASM2d model to a full-scale wastewater treatment plant (WWTP), including both biological and chemical phosphorus removal and a model of the sedimentation process. Second, based on the calibrated model a benchmark model is developed and various control strategies for biological phosphorus removal are tested. Experiences and knowledge gained from the strategies presented and discussed in this paper are vital inputs for the full-scale implementation of a control strategy for biological phosphorus removal at Avedøre WWTP, which is described in another paper. The two papers hence show a way to bridge the gap from model to full implementation.

A evapotranspiração da cultura pode ser determinada de forma precisa através da utilização de lisímetros de pesagem eletrônica ou mecânica. Objetivou-se, com este trabalho, o desenvolvimento e calibração de um mini-lisímetro de pesagem mecânica de baixo custo para a determinação da evapotranspiração de referência. O mini-lisímetro consiste de um tanque de PVC, apoiado sobre anteparos de metal fixos, com um dreno na base do tanque, as células de carga (4 células) são oriundas de uma balança de pesagem doméstica. O sistema de aquisição e armazenamento dos dados utiliza um micro-controlador. Para calibração dos lisímetros utilizou-se massas de referência constituídas de 4 unidades (10; 5; 0,5 e 0,2 kg) que foram adicionadas de forma crescente e decrescente em 5 ciclos de medição afim de se obter a curva de calibração do equipamento. Foram calculados o erro máximo absoluto, erros de repetitividade, linearidade e histerese do instrumento. Ocorreu uma tendência nos desvios em relação a massa aplicada resultante da calibração, sendo a maior na máxima carga aplicada (35,7 kg), com valor de -1,52 kg. O erro de não-linearidade foi o que mais influenciou na acurácia do mini-lisímetro, com 1,68 Kg e 7,93% de influência na medição, nos ciclos de carregamento e descarregamentos, respectivamente. A histerese apresentou interferência baixa na medição, 0,06%. O erro máximo absoluto apresentou um valor alto de 1,5 kg (0,35%), sendo necessário novos ajustes em seu hardware e células de carga.

L.ACCURACY OF A MINI-WEIGHING LYSIMETER ELECTRONIC LOW COST 2 ABSTRACT To apply a blade of adequate irrigation is necessary to know the crop water demand, estimating precisely its evapotranspiration for efficient irrigation management. The evapotranspiration of culture can be determined precisely by the use of electronic or mechanical weighing lysimeters. The objective of this study was to development and calibration of a mini-lysimeter mechanical weighing low cost for the determination of the reference evapotranspiration. The mini-lysimeter consists of a PVC tank, resting on fixed metal shields, with a drain at the base of the tank, the load cells (four cells) are derived from a domestic weighing balance. The system acquisition and storage of data using a micro-controller. For calibration of the lysimeters was used reference masses consisting of 4 units (10, 5, 0.5 and 0.2 kg) were added in increasing and decreasing order in 5 measuring cycles in order to obtain the calibration curve of equipment. Were calculated the maximum absolute error, repeatability errors, linearity and hysteresis of the instrument. There has been a trend in deviations from the applied resulting mass calibration, the higher the maximum applied load (35.7 kg), with a value of -1.52 kg. The non-linearity error it was what influenced more in accuracy of the mini-lysimeter with 1.68 kg and 7.93 of influence in the measurement, us cycles of loading and unloading, respectively. The Hysteresis showed low interference in the measurement, 0.06%. The maximum absolute error showed a high value of 1.5 kg (0.35%), requiring new settings on your hardware and load cells. Keywords: calibration, evapotranspiration, irrigation management.

Biomass potency in Indonesia is very abundant both from the animal manure or plant. Agriculture and plantations waste which are abundant can be utilized as the energy source. One of them is the rice husk. This experiment used rice husk gasification method with downdraft gasifier to turn it into a combustible gas that will be burned in the combustion chamber cyclone. The advantage of gasification compared to the method of the direct combustion is cleaner burning and particulates and contaminants can be removed before burning. The cyclone fuels can produce good mixing which is suitable for gas with low calorific value. The composition of syngas produced by gasification of rice husk are H2 13,6%, CO 14,9%, CO2 12,9% dan CH4 2,3% [1]. After leaving the reactor syngas entry cyclone separator to remove moisture and contaminants, and then go to the storage tank and eventually went to cyclone fuel to be burned after mixing with air through a different inlet. After that the different value of AFR will vary to see the changes in temperature of the flame, the fire position in the combustion chamber and the flame shape. From the experimental results in AFR = 1.59 fire in the combustion chamber air beetween 1 and 2, in the AFR = 1.14 The fire in the combustion chamber in the plane 2, in AFR = 0.69 fire in the combustion chamber 3 and in the air beetween AFR = 0.27 fire outside the combustion chamber after mixing withfresh air.

With the boom of the fashion market and people’s daily needs for beauty, clothing matching has gained increased research attention. In a sense, tackling this problem lies in modeling the human notions of the compatibility between fashion items, i.e., Fashion Compatibility Modeling (FCM), which plays an important role in a wide bunch of commercial applications, including clothing recommendation and dressing assistant. Recent advances in multimedia processing have shown remarkable effectiveness in accurate compatibility evaluation. However, these studies work like a black box and cannot provide appropriate explanations, which are indeed of importance for gaining users’ trust and improving their experience. In fact, fashion experts usually explain the compatibility evaluation through the matching patterns between fashion attributes (e.g., a silk tank top cannot go with a knit dress). Inspired by this, we devise an attribute-wise explainable FCM solution, named ExFCM , which can simultaneously generate the item-level compatibility evaluation for input fashion items and the attribute-level explanations for the evaluation result. In particular, ExFCM consists of two key components: attribute-wise representation learning and attribute interaction modeling. The former works on learning the region-aware attribute representation for each item with the threshold global average pooling. Besides, the latter is responsible for compiling the attribute-level matching signals into the overall compatibility evaluation adaptively with the attentive interaction mechanism. Note that ExFCM is trained without any attribute-level compatibility annotations, which facilitates its practical applications. Extensive experiments on two real-world datasets validate that ExFCM can generate more accurate compatibility evaluations than the existing methods, together with reasonable explanations.
