We have performed density-functional calculations in order to clarify atomic structures and energetics of surface steps on SiC. The obtained energetics of distinct step types on vicinal 3C-SiC(111) surfaces which correspond to 4H- and 6H-SiC(0001) surfaces reveals the atom-scale reason for the experimental observation in the past that the step morphology is straight for the SiC(0001) surfaces inclined toward the 〈1-100〉 direction while it is meandering for the 〈11-20〉 inclined surfaces. The calculations clarify the rebonding between upper- and lower-terrace edge atoms, which is decisive for the energetics of the atomic steps.

The interaction of vapor phase P2 with the [Formula: see text] monolayer surface at room temperature and elevated temperature has been monitored by scanning tunneling microscopy (STM) and spectroscopy (STS) in conjunction with Auger electron spectroscopy and low-energy electron diffraction (LEED). The surface rection can be readily followed by STM because of the very different contrast of the reacted areas in the STM images. The reaction develops around overlayer defects at room temperature and appears to be diffusion-limited, whereas at 300°C the reaction is initiated at the step edges, from which the reaction front progresses onto the lower terrace areas. At elevated temperature several ordered surface reconstructions, showing different STS fingerprints, are detected on the P–In/Si(111) surfaces, which are associated tentatively with P- and Si-terminated structures and an ordered InP phase.

Prayer is an obligation that must not be abandoned except because of aging or obstruction that is justified by religious law, such as; women who have menstruation or postpartum. The person who leaves the prayer without a reason that is justified in the shari'ah of the law is an infidel. One of the conditions of prayer is in a holy and clean condition, but researchers can see the condition of a prayer house or mosque, the condition of the lower floor is dirty because many people pass by stepping on the floor of the lower terrace with the condition of using shoes. There is also a new one from the bathroom with no feet who then stepped on the floor. Stepping on a dirty floor will cause doubts. To cancel these doubts, it is better for researchers to maintain proper ablution conditions. Therefore, researchers made Automatic Foot Washers with Pear Sensors Based on Atmega Microcontroller 16. PIR (Pasive Infra Read) is one tool that can be used as a sensor to detect human presence which is then developed into an automatic footwashing device. And with the addition of an automatic door, the pilgrims will be orderly to wash their feet before entering the mosque. As well as the drying fan that the researcher added after the doorstop will make the pilgrim's feet dry immediately before stepping on the prayer area at the mosque.

Abstract The settlement and necropolis of Grakliani Hill are located in Central Transcaucasia, Georgia. Excavations of the settlement on the eastern slope and the necropolis on the south-western part of the hill demonstrated that the site had been occupied between the Chalcolithic and the Late Hellenistic periods. The most interesting remains of buildings belong to 2nd and 1st millennium BC. Several sanctuaries of this period were excavated. A monumental altar was discovered in the eastern part of the settlement. The altar was located in the north-western corner of a building. On its eastern side there was an ash pit with a platform along the northern wall. The platform was used for placing offerings, including a South Mesopotamian seal. An architectural complex of the following period (450-350 B.C) was discovered in the western part of the lower terrace. It consisted of three main rooms and three store-rooms. Burials of various periods were discovered in the western part of the hill’s southern slope. The earliest one is a pit-burial dating to the Early Bronze Age, the latest one belongs to the 2nd century BC. After analyses of the finds several directions of cultural and commercial links were identified: Colchis, Persia, Phoenicia, Mesopotamia, Egypt, Asia Minor.

The structure of a clean Si(100) and a Ni-contaminated si(100) was investigated using scanning tunneling microscopy. The clean Si (100) shows the 2 × 1 reconstruction with a surface dimer vacancy density less than 2%. The major defects on the clean surface are a single dimer vacancy and the C defect. A small amount of Ni on the surface drastically changes the surface structure and produces 2 × n reconstructions. The formation of vacancy clusters is favored. A rebonded SB step is preferred on the clean Si(100) while a nonrebonded SB step with a split-off dimer is mainly observed on the Ni-contaminated Si(100) and in the vicinity of dimer vacancies of the lower terrace on the clean Si(100).

The landslide in Quaternary loess sediments occurs a balka at the Samets River left bank and is limited by Metropolitan Sheptytsky St. in the West, Kuprin St. in the North, Kuprin lane in the East (the last locates 140–250 m to the East of the plot), two ponds in the South. The elevation between Kuprin St. and ponds distinguish 42 m, the length from North to South 820 m, and the width 390 m. The exact dates of landslide shift, as well as geological, cartographic or other materials like that at the time of sliding (the end of the 1950s for the first shift and the first half of the 1970s for the second one) were not found, this research bases on reconstruction of terrain morphology by large-scale maps, plans from the late nineteenth till early twenty-first centuries. Balka’s slopes and the adjacent areas of the loess plateau undergone significant morphological changes after the landslide, modern terrain is allocated to anthropogenic surfaces, such as plane watershed, built-up without significant vertical planning; built-up terraced slopes of plateau, balkas and riverbank; three artificial terraces on the main body, as well as steep and very steep ledges and outcrops (maximum height 9 m), surfaces with mosaic combination of small terraces, flattering slopes and steep ledges, hilled surface. The landslide toe came to the flood terrace; this part of the landslide was later completely changed after construction of the dam, ponds and channel in the late 1980s. There is a connection between earlier anthropogenic terrain changes and landslide: first of all, the eastern and western scarps were connected to the ledges of quarries. The modern lower terrace has approximately the same absolute heights as level of the western quarry area before sliding. The north scarp mostly repeated the contour shape of balka but smoothed out smaller bends. In the Northeast, the landslide captured part of the plateau, the present level of the middle terrace is close to the eastern quarry level. Because of landsliding and repeated redevelopment of the territory, the situation with the slope exposures was simplified: except for the scarps, southern exposures dominate. In 2015 curved tree trunks, tilted poles, cracks and other destruction of buildings indicate the slow earthflow within the area. Key words: urban landslides, loess landslides, terrain morphology, Khmelnytskyi City.

The paper provides an assessment of the frequency of apple fruiting of different maturation periods growing on the lower terrace of the Vs. M. Krutovsky Botanical garden in the period from 2015 to 2018 according to the following parameters: the number of fruit-bearing trees, the number of fruits on the tree, yield. In the conditions of the Botanical garden, located in the green zone of Krasnoyarsk, the timing of the onset of removable fruit maturity varies significantly. The variability of the fruit formation period depends on the weather conditions in the summer and primarily on the temperature regime. The optimal time for collecting varieties of the summer ripening period is August, and for winter varieties is September, since by this time the fruits of these groups acquire a characteristic color and size. It was found that during the research period, most of the trees of the presented varieties fruited annually. Varieties and individual specimens with an annual plentiful fruiting and maximum fruit weight of fruits are selected: Bismark, Belyy Naliv, General Orlov, Grushovka moskovskaya, Zolotoy Ship, Papirovka, which is a positive factor in a sharply continental climate. It was found that in Siberia, varieties adapted to the European zone have successfully adapted and can be grown in these and similar climatic conditions and can be recommended for further breeding.

AbstractCuraçao has reef terraces with the potential to provide sea-level histories of interglacial periods. Ages of the Hato (upper) unit of the “Lower Terrace” indicate that this reef dates to the last interglacial period, Marine Isotope Stage (MIS) 5.5. On Curaçao, this high sea stand lasted at least 8000 yr (~ 126 to ~ 118 ka). Elevations and age of this reef show that late Quaternary uplift rates on Curaçao are low, 0.026–0.054 m/ka, consistent with its tectonic setting. Ages of ~ 200 ka for corals from the older Cortalein unit of the Lower Terrace correlate this reef to MIS 7, with paleo-sea level estimates ranging from − 3.3 m to + 2.3 m. The estimates are in agreement with those for MIS 7 made from other localities and indicate that the penultimate interglacial period was a time of significant warmth, on a par with the present interglacial period. The ~ 400 ka (MIS 11) Middle Terrace I on Curaçao, dated by others, may have formed from a paleo-sea level of + 8.3 to + 10.0 m, or (less likely) + 17 m to + 20 m. The lower estimates are conservative compared to previous studies, but still require major ice sheet loss from Greenland and Antarctica.
