Introduction. The submergence by underground water remains one of the problems in urban construction. It is also associated with the movement of groundwater under buildings and structures. Such processes are non-stationary and their calculation is complex. The paper begins the series of researches on the methodology for solving problems of filtering groundwater while protecting against flooding in urban construction by using an operator method. Oliver Heaviside began the practical application of mathematical operators for solving engineering problems. The operator method with Laplace transformations was used. It was shown how, with the help of the Internet and Maxima program, it is easy to make inverse Laplace transformations.Methods and materials. The author considered the decision on the submergence of the city road in the presence of a dome watering under asphalt pavement in the dirt road foundation. At the same time, for filtration problems of such type, the author took into account the compaction of the engineering zone of the soil under the road. The paper showed how to solve the complex non-stationary problem of spreading the dome of the flooding under the city road. The technology of the solution is presented not only with all the mathematical details of the operator method, but also provided with new physical representations. Such an original approach, by the author’s opinion, would help better understanding of the flooding process physics in urban construction. Moreover, it would allow solving problems of protection against flooding by a new, more efficient way, taking into account the real non-stationary processes of filtration of groundwater in built-up areas.Discussion. As a result, the author presents anew statement of the operator method for solving the submergence specific problem in urban construction. First, a specific example demonstrates how to use the Internet and the license-free Maxima program. In this case, the simplest  case is taken, in the form of the electricity and filtration analogy. Then the author considers the filtration spreading of the domed man-made groundwater beneath the city road. Therefore, the paper demonstrates new solutions for non-stationary filtration of groundwater in the engineering zone, which are also compared with the world practice results.Conclusions. The author presents the methodology for solving unsteady groundwater filtration problems for the submergence protection in urban construction by using the operator method and Laplace transformations. Such decisions make it possible to obtain convenient engineering formulae, by which groundwater levels, substantiate practical solutions and measures for protection against submergence in urban construction could be found. The author intends to further development of such scientific ideas and solutions for submergence protection in the built-up areas.

Fluctuation Method

Recharge estimation accurately is crucial to proper groundwater resource management, for the groundwater is dynamic and replenished natural resource. Usually recharge estimation depends on the; the water balance, water levels, and precipitation. This paper is studying the south-middle part of Erbil basin, with the majority of Quaternary sediments, the unconfined aquifer system is dominant, and the unsaturated zone is ranging from 15 to 50 meters, which groundwater levels response is moderate. The purpose of this study is quantification the natural recharge from precipitation. The water table fluctuation method is applied; using groundwater levels data of selected monitoring wells, neighboring meteorological station of the wells, and the specific yield of the aquifers. This method is widely used for its simplicity, scientific, realistic, and direct measurement. The accuracy depends on the how much the determination of specific yield is accurate, accuracy of the data, and the extrapolations of recession of groundwater levels curves of no rain periods. The normal annual precipitation there is 420 mm, the average recharge is 89 mm, and the average specific yield is around 0.03. The data of one water year of 2009 and 2010 has taken for some technical and accuracy reasons.

Trade is a form of business that is run by many people around the world, ranging from trading various kinds of daily necessities or primary needs, to selling the need for luxury goods for human satisfaction. For that, to overcome the many needs of life, they try to outsmart them buy products that are useful, economical and efficient. One of the markets they aim at is the second-hand market or the so-called trashy market. As for a trader at a trashy market, they aim to sell in the used goods market with a variety of reasons. These reasons include; first, because it is indeed to fulfill their needs. Second, the capital needed to trade at trashy markets is much smaller than opening a business where the products come from new goods. Third, used goods are easily available and easily sold to buyer. Here the researcher will discuss the behavior of Muslim traders in a review of Islamic business ethics (the case in the Jagalan Kediri Trashy Market). Kediri Jagalan Trashy Market is central to the sale of used goods in the city of Kediri. Where every day there are more than 300 used merchants who trade in the market. The focus of this research is how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in general. Then, from the large number of traders, of course not all traders have behavior in accordance with Islamic business ethics, as well as traders who are in accordance with the rules of Islamic business ethics. This study aims to determine how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in buying and selling transactions and to find out how the behavior of Muslim traders in the Jagalan Kediri Trashy Market in reviewing Islamic business ethics.

Flooding is a dangerous phenomenon, causing emergency situations and causing material damage, capable of damaging health, and even death of people. To reduce the risk and economic damage from flooding, it is necessary to forecast flooding areas. An effective method of forecasting emergency situations due to flooding is the method of remote sensing of the Earth with integration into geoinformation systems. With the help of satellite imagery, a model of flooding was determined based on the example of Tavda, the Sverdlovsk Region. Space images are loaded into the geoinformation system and on their basis a series of thematic layers is created, which contains information about the zones of possible flooding at given water level marks. The determination of the area of flooding is based on the calculation of the availability of maximum water levels at hydrological stations. According to the calculated security data, for each hydrological post, flood zones are constructed by interpolation between pre-calculated flood zones of standard security. The results of the work can be used by the Main Directorate of the Ministry for Emergency Situations of Russia for the Sverdlovsk Region.

Magnanimity is a virtue that has led many lives. Foregrounded early on by Plato as the philosophical virtue par excellence, it became one of the crown jewels in Aristotle’s account of human excellence and was accorded an equally salient place by other ancient thinkers. One of the most distinctive elements of the ancient tradition to filter into the medieval Islamic and Christian worlds, it sparked important intellectual engagements there and went on to carve deep tracks through several later philosophies that inherited from this tradition. Under changing names, under reworked forms, it continued to breathe in the thought of Descartes and Hume, Kant and Nietzsche, and their successors. Its many lives have been joined by important continuities. Yet they have also been fragmented by discontinuities—discontinuities reflecting larger shifts in ethical perspectives and competing answers to questions about the nature of the good life, the moral nature of human beings, and their relationship to the social and natural world they inhabit. They have also been punctuated by moments of controversy in which the greatness of this vision of human greatness has itself been called into doubt. This volume provides a window to the complex trajectory of a virtue whose glitter has at times been as heady as it has been divisive. By exploring the many lives it has lived, we will be in a better position to decide whether and why this is a virtue we might still want to make central to our own ethical lives.

Krakow has an extensive district heating network, which is approximately 900 km long. It is the second largest city in terms of the number of inhabitants in Poland, resulting in a high demand for energy—for both heating and cooling. The district heating of the city is based on coal. The paper presents the conception of using the available renewable sources to integrate them into the city’s heating system, increasing the flexibility of the system and its decentralization. An innovative solution of the use of hybrid, modular heat pumps with power dependent on the needs of customers in a given location and combining them with geothermal waters and photovoltaics is presented. The potential of deep geothermal waters is based on two reservoirs built of carbonate rocks, namely Devonian and Upper Jurassic, which mainly consist of dolomite and limestone. The theoretical potential of water intake equal to the nominal heating capacity of a geothermal installation is estimated at 3.3 and 2.0 MW, respectively. Shallow geothermal energy potential varies within the city, reflecting the complex geological structure of the city. Apart from typical borehole heat exchangers (BHEs), the shallower water levels may represent a significant potential source for both heating and cooling by means of water heat pumps. For the heating network, it has been proposed to use modular heat pumps with hybrid sources, which will allow for the flexible development of the network in places previously unavailable or unprofitable. In the case of balancing production and demand, a photovoltaic installation can be an effective and sufficient source of electricity that will cover the annual electricity demand generated by the heat pump installation, when it is used for both heating and cooling. The alternating demand of facilities for heating and cooling energy, caused by changes in the seasons, suggests potential for using seasonal cold and heat storage.

AbstractHydrogeological responses to earthquakes such as changes in groundwater level, temperature, and chemistry, have been observed for several decades. This study examines behavior associated with ML 5.8 and ML 5.1 earthquakes that occurred on 12 September 2016 near Gyeongju, a city located on the southeast coast of the Korean peninsula. The ML 5.8 event stands as the largest recorded earthquake in South Korea since the advent of modern recording systems. There was considerable damage associated with the earthquakes and many aftershocks. Records from monitoring wells located about 135 km west of the epicenter displayed various patterns of change in both water level and temperature. There were transient-type, step-like-type (up and down), and persistent-type (rise and fall) changes in water levels. The water temperature changes were of transient, shift-change, and tendency-change types. Transient changes in the groundwater level and temperature were particularly well developed in monitoring wells installed along a major boundary fault that bisected the study area. These changes were interpreted as representing an aquifer system deformed by seismic waves. The various patterns in groundwater level and temperature, therefore, suggested that seismic waves impacted the fractured units through the reactivation of fractures, joints, and microcracks, which resulted from a pulse in fluid pressure. This study points to the value of long-term monitoring efforts, which in this case were able to provide detailed information needed to manage the groundwater resources in areas potentially affected by further earthquakes.
