In this article the tasks of modeling the flow distribution are considered, and since the consumers of this system are pumping stations, the first place is put forward not social (as in the second rise), and economic (energy) criteria. The water pressure at the pump inlets is determined by the geodesic levels of the pumps. In wells can be installed various pumping equipment, different in pressure and performance, resulting in a significant difference in the pressure produced by the pumping equipment. In the wells can be installed various pumping equipment, different in pressure and performance, as a result of which there is a significant difference in the pressure generated by the pumping equipment. The article presents a transformed version of the nonlinear and linear models of operational management as applied to water-lifting stations. The governance model allows tracking the transition of the system to a new state and the change of parameters along individual lines within this transition. Herewith, if from two wells the water supply to the manifold increases in accordance with a given forecast, then from the third - the water supply decreases. According to the results of modeling of water supply stations can be built throttle characteristic. The synthesis of throttle characteristics obtained on the basis of the operational control model allows for the operational control of the water supply modes to the clean water tank, which is an alternative to direct modeling. Both methods can be implemented as part of the operation of automated control systems for pump stations I and II lifting. The most interesting is the scheme of water supply stations without back pressure with the predominant location of wells with less powerful submersible pumps closer to the area of low pressures in the collector nodes. The results of numerical simulation are presented in the form of throttle characteristics, that is, the dependence of the flow rate of water supplied from a well by a submersible pump through a choke, on its hydraulic resistance coefficient. Due to the throttle characteristics, it is possible to determine the extremely high value of the water flow entering the clean water tank, as well as the possibility of modeling the most economical mode of operation of wells.

Abstract Managing the distribution of water resources for the southern regions of Russia is of great importance in connection with limiting the consumption of fresh water. The use of saline water can lead to soil salinization and negatively affect crop production. The article deals with the problem of constructing a sequential automaton for controlling the system of switching networks when watering plants on the example of the sanatorium “Rus” in the city of Anapa, Krasnodar Territory. The Mediterranean zone, where the city of Anapa is located, is characterized by a low level of precipitation, which leads to the need for artificial irrigation of plants. The existing irrigation system using a water tank truck based on the GAZ-53 is physically outdated, which required the development of a modern automated system. The flower alleys, located on the territory of the sanatorium, were structured in a tree-like form. The construction of a control device based on rigid logic is based on the Mealy automaton. A method for constructing a control system for a tree-like water supply network has been developed, which makes it possible to control the main, distribution and supply branches. A block diagram of an irrigation machine has been developed, which has a tree-like branching, which shows control signals and states of transitions. Synthesized logical equations for the control of the water supply system, using a blocking control system with feedback. It is proposed to use the Omron programmable logic controller and CX-One software as software and hardware. The distribution of the address space of the controller is shown. Simulation modeling of the system operation was carried out, which showed the correct logic of control over the work of water pressure supply in water pipelines. Implementation of the developed system will improve the quality of irrigation of plants and minimize the cost of irrigation.

Water is one of the financial needs for life. In everyday life we can see the importance of water for all living things, as well as human beings who also need water very much. In Jorong Dalam Nagari Barulak Tanah Datar, the need for clean water is difficult to obtain. This is because the position of this area is in the highlands. During the summer in the highlands it is very difficult to find a source of clean water, so that to meet these water needs, people get it by buying. The solution to overcome this problem is to apply science and technology in the form of a hydram pump that utilizes water pressure from a reservoir from a spring. Then the water is pumped through a pipeline to the divider tank at an elevated area. Clean water supply using a hydram pump is able to distribute water by 18.43 liters/min. So that the performance of a hydram pump continuously (within 24 hours) can supply of water as much as 26.54 m3/day. Applying appropriate technology in the form of a hydram pump as an effort to optimize the supply of clean water from the lowlands to the highlands so that it can address the water needs in the Nagari Barulak community. Utilizing the potential of existing water resources has an impact on increasing activities and reducing public funding for buying clean water.

Discusses the negative manifestations in the operation of water intaking constructions from underground. In the mode of operation of each pump is influenced by external and internal characteristics of the system wells – submersible pump – common culvert – the clean water tank. Methods Mathematical model operation of management process of collaboration of system a water well – a prefabricated conduit with definite forms of boundary conditions. Schemes of an arrangement are shown of water wells and a prefabricated conduit. Results Interference of a duty of certain wells and a prefabricated conduit is studied, unstable work of submersible pumps is defined. The scheme of water delivery is presented to the pure tank on separate pressure pressure lines. To ensure the stability of the pumping equipment, the characteristics of the diameter of the water conduit (its hydraulic resistance) are determined depending on the total hydraulic resistance of the well equipment (well filter, pump, fittings) and the well pipeline. Monitoring of water intake structures allows you to set technical indicators for choosing an independent scheme, to choose the right equipment, taking into account the joint operation of the system borehole - submersible pump - collecting water conduit - RFI. Conclusion Energetically optimal work of water intake structures with separate pressure lines, helps to reduce water losses, while achieving significant savings in electricity. The most favorable for the submersible pump is work on the clean water tank, and not on the prefabricated conduit.

ABSTRACTThe clean water supply system network on Lengkang Kecil Island was developed in 2019. A small portion of the community's freshwater comes from harvesting rainwater and dug wells, which are only obtained during the rainy season. The primary source of clean water used by the community comes from underwater pipelines with a daily discharge of 0.86 l/sec. The water supply of the Lengkang Kecil Island community is 74.3 m3/day, with 146 House Connections (HCs) and to serve public facilities such as elementary schools, primary health centers, and mosques. Hydraulic evaluation of clean water distribution using EPANET 2.0 software on flow velocity shows the lowest rate of 0.29 m/s and the highest of 1.21 m/s. The lowest pressure value in the distribution system is 6.94-6.96 m and headloss units in the range 0.08-0.25 m/km. These three criteria are still within the distribution network design criteria (feasible). A carbon footprint can be calculated from each activity from the analysis of the evaluation of clean water distribution networks. The most massive emissions came from pumping activities with 131 kg CO2-eq, followed by emissions from wastewater 62.5 kgCO2-eq. Further research is needed to determine the quality of wastewater and the design for a centralized wastewater treatment plant (IPALT) to improve Lengkang Kecil Island residents' living standards.Keywords: Lengkang Kecil Island, water, EPANET, carbon footprintABSTRAKJaringan sistem penyediaan air bersih pada Pulau Lengkang Kecil dimulai pada tahun 2019.

Human-robotic interaction system are increasingly becoming integrated into industrial, commercial and emergency service agencies. It is critical that human operators understand and trust automation when these systems support and even make important decisions. The following study focused on human-in-loop telerobotic system performing a reconnaissance operation. Twenty-four subjects were divided into groups based on level of automation (Low-Level Automation (LLA), and High-Level Automation (HLA)). Results indicated a significant difference between low and high word level of control in hit rate when permanent error occurred. In the LLA group, the type of error had a significant effect on the hit rate. In general, the high level of automation was better than the low level of automation, especially if it was more reliable, suggesting that subjects in the HLA group could rely on the automatic implementation to perform the task more effectively and more accurately.

Abstract Background Flow diverters (FDs) are widely used in the treatment of intracranial aneurysms, but the required medication increases the risk of haemorrhagic complications and limits their use in the acute setting. Surface modified FDs may limit the need for dual antiplatelet therapy (DAPT). Hydrophilic polymer coating (HPC) may reduce the need of medication. Methods This explorative study, approved by the local authorities and the local welfare committee, compared stent behaviour and overall tissue response between HPC-coated FDs and uncoated FDs, both implanted into the common carotid arteries of eight New Zealand white rabbits. Endothelialisation, inflammatory response, and performance during implantation were assessed. Angiographic follow-up was performed to observe the patency of the devices after implantation and after 30 days. Histological examinations were performed at 30 days to assess foreign body reaction and endothelialisation. Kruskal-Wallis and Wilcoxon tests were used to compare non-parametric variables. Results Angiography showed that both coated and uncoated FDs performed well during implantation. All devices remained patent during immediate follow-up and after 30 days. Histopathology showed no significant difference in inflammation within the vessel wall between the two cohorts (2.12 ± 0.75 vs. 1.96 ± 0.79, p = 0.7072). Complete endothelialisation of the stent struts was seen with very similar (0.04 ± 0.02 mm vs. 0.04 ± 0.03 mm, p = 0.892) neoendothelial thickness between the two cohorts after 30 days. Conclusion Taking into account the limitation in sample size, non-significant differences between the HPC-coated and uncoated FDs regarding implantation, foreign body response, and endothelialisation were found.

This study aimed to assess the awareness and performance of Qom citizens towards using disinfectants and compared its relationship with geographical distribution of COVID-19 outbreak in Qom, Iran. The study was conducted by a researcher-made questionnaire during April and May, 2020. COVID-19 incidence data for each district of city was obtained from health department of Qom province. Data were analyzed using Excel, SPSS and ArcView (GIS) softwares. It was found that the highest level of citizens’ awareness (52%) was in the weak range while their performance (56%) was in the good range. According to Spearman’s correlation analysis, there was a strong correlation (rho 0.95) between the total mean of awareness and performance (p < 0.01). The highest incidence rate of COVID-19 was in district 7 which had the lowest mean score in both awareness and performance. In addition, the results of ANOVA (LSD—least significant difference) showed that there was a significant difference (p < 0.05) between district 7—with lower mean scores in awareness and performance—and other districts. Overall, it is concluded that citizens’ awareness level was lower than that of their performance. This conclusion not only calls for more training programs to be implemented in public places, schools, universities and governmental offices, but it also necessitates maintaining a proper and timely training about using disinfectants.
