2020 is a very disturbing year for the whole world because in 2020 there is a deadly virus, the virus is called Covid-19. The Indonesian government has a strategy to deal with the Covid-19 virus, namely by implementing Large-Scale Social Restrictions (PSBB). Where the implementation of this PSBB requires residents to do more activities at home. To carry out activities at home, internet access is needed. Therefore, providers are the companies that benefit the most, providers are companies that provide internet services, one of which is XL Axiata. During the Covid-19 pandemic, XL Axiata company wants to conduct analysis for XL Axiata in the next year, whether the traffic of XL Axiata users has increased or decreased and how many devices need to be upgraded or safe. In conducting this analysis, it is necessary to perform fast data processing, data processing using the Data Mining method with Linear Regression techniques. The data to be processed will be obtained from the XL Axiata company, namely XL Axiata traffic data. By processing data using Linear Regression results in future predictions, the West Jakarta Municipality has increased per week by an average of 0.12%, the East Jakarta Municipality has decreased per week by an average of 0.27%, the Central Jakarta Municipality experiences the decline per week by an average of 2.31%, the South Jakarta Municipality experienced an increase per week by an average of 1.17%, and in the North Jakarta Municipality it decreased per week by an average of 0.12%.

Mara Lake, British Columbia straddles the boundary between the Monashee Group on the east and the Mount Ida Group on the west. Correlation of units across the southern end of Mara Lake indicates lithologic continuity between parts of the groups. Both groups have experienced four phases of deformation. Phases one and two are tight and recumbent, trending to the north and to the west, respectively. Phases three and four are open to closed and upright, trending northwest and northeast, respectively. Second-phase deformation includes large-scale tectonic slides that separate areas of consistent vergence. Slide surfaces are folded by third- and fourth-phase structures and outline domal outcrop patterns. Metamorphic grade increases from north to south along the west side of Mara Lake. Calc-silicate reactions involving the formation of diopside are characteristic. From west to east increasing grade is evident in the reaction of muscovite + quartz producing sillimanite + K-feldspar + water. These prograde reactions are related to relative position in the second-phase structure. The highest grade is located near the lowest slide surface. Greenschist conditions accompanied phase-three deformation. Fourth phase is characterized by hydrothermal alteration, brittle fracturing, and local faulting. First-phase deformation appears to be pre-Late Triassic whereas second and third phases are post-Late Triassic and pre-Cretaceous. The fourth phase is part of a regional Tertiary event. The third folding event is correlated with the development of the Chase antiform and the second-phase folding is related to the pervasive east–west fabric of the Shuswap Complex. The timing of these events indicates that the metamorphic core zone of the eastern Cordillera was relatively rigid during the late Mesozoic foreland thrust development. Ductile deformation significantly preceded thrusting and developed a fabric almost at right angles to the trend of the thrust belt.

Abstract The article discusses visions of future warfare articulated in recent Russian military publications. There seems to be agreement among Russian scholars that future war will be triggered by Western attempts to promote Western political and economic interests while holding back Russia's resurgence as a global power. The future war with the West is viewed as inevitable in one form or another, whether it is subversion and local wars or large-scale conventional war. While the danger of conventional war has declined, according to several scholars, the West is understood to have a wide range of non-kinetic means at its disposal that threaten Russia. In order to withstand future dangers, Russia has to be able to meet a large number of kinetic and non-kinetic threats at home and abroad.

The Tell-Rif (Tell in Algeria and Tunisia; Rif in Morocco) is the orogenic system fringing to the south the West Mediterranean basins. This system comprises three major tectonic-palaeogeographic zones from north to south: (1) the internal zones (AlKaPeCa for Alboran, Kabylies, Peloritan, Calabria) originating from the former northern European margin of the Maghrebian Tethys, (2) the “Flyschs zone” regarded as the former cover of the oceanic domain and (3) the external zones, forming the former southern Maghrebian Tethys margin more or less inverted. The Tell-Rif is interpreted as the direct result of the progressive closure of the Maghrebian Tethys until the collision between AlKaPeCa and Africa and, subsequently, the propagation of the deformation within Africa. This gives a consistent explanation for the offshore Neogene geodynamics and most authors share this simple scenario. Nevertheless, the current geodynamic models do not completely integrate the Tell-Rif geology. Based on the analysis of surface and sub-surface data, we propose a reappraisal of its present-day geometry in terms of geodynamic evolution. We highlight its non-cylindrical nature resulting from both the Mesozoic inheritance and the conditions of the tectonic inversion. During the Early Jurassic, we emphasize the development of NE-SW basins preceding the establishment of an E-W transform corridor connecting the Central Atlantic Ocean with the Ligurian Tethys. The Maghrebian Tethys developed just after, as the result of the Late Jurassic-Early Cretaceous left-lateral spreading between Africa and Iberia. By the Late Cretaceous, the occurrence of several tectonic events is related to the progressive convergence convergence between the two continents. A major pre-Oligocene (pre-35 Ma) compressional event is recorded in the Tell-Rif system. The existence of HP-LT metamorphic rocks associated with fragments of mantle in the External Metamorphic Massifs of the Eastern Rif and Western Tell shows that, at that time, the western part of the North-African margin was involved in a subduction below a deep basin belonging to the Maghrebian Tethys. At the same time, the closure of the West Ligurian Tethys through east-verging subduction led to a shift of the subduction, which jumped to the other side of AlKaPeCa involving both East Ligurian and Maghrebian Tethys. Slab rollback led to the development of the Oligo-Miocene back-arc basins of the West-Mediterranean, reworking the previous West Ligurian Tethys suture. The docking of AlKaPeCa against Africa occurred during the Late Burdigalian (17 Ma). Subsequently, the slab tearing triggered westward and eastward lateral movements that are responsible for the formation of the Gibraltar and Tyrrhenian Arcs respectively. The exhumation of the External Metamorphic Massifs occurred through tectonic underplating during the westward translation of the Alboran Domain. It resulted in the formation of both foredeep and wedge-top basins younger and younger westward. The lack of these elements in the eastern part of the systems signs a different evolution dominated by frontal accretion. In the discussion, we precisely address the origin of the non-cylindrical behavior of the orogenic system and question the mechanisms explaining at large scale the phases of coupling/uncoupling between the major plates.

Abstract In 2014, Yunnan Provincial Institute of Cultural Relics and Archaeology and other institutions conducted large-scale excavation to the Dabona Cemetery located in Dabona Village and to its east of the Liuchang Town, Xiangyun County. The west zone of the Dabona Cemetery had widely distributed early cultural remains, including house foundations, postholes, ash pits, ash ditches, etc. The east zone consisted of two sections distributed in the north-south direction, in the north section of which 25 burials were recovered; among these burials, six were large-sized ones with lengths more than 6m, and the other were medium- and small-sized burials. The grave goods unearthed from these burials reflected that the dates of the remains and burials were roughly in the Warring-States Period to the Qin and Han Dynasties. The area where these remains and burials were located was the main inhabited area of the people of Kunming ethnic group; this excavation provided important materials for the researches on the features and the social situations of the bronze cultures in the Erhai Lake region.

Abstract The Lithuanian-Latvian illative was formed from the IE accusativus directivus and the local postposition *-ā́. Traces of the postponed *-ā́ have been preserved in yrà ‘is, are; OLith. there is, there are’ < *ī-r-ā́, and Lith. čià ‘here’ < *tj-ā́. Typologically, the Baltic illative can be compared to Greek derivatives with -δε, e.g. οἴκα-δε ‘homewards; at home’. As for the origin of the postponed *-ā́, two hypotheses can be formulated: 1. *-ā́ comes from the IE allative postposition *-eh₂ (see Hajnal 1992); 2. *-ā́ boils down to the instr. sg. of the anaphoric pronoun *h₁o-h₁. The primary illative plural ended in -s-ā́, e.g. OLith. (debesisa) ‘into heaven’. The postposition -na, which can be found e.g. in the ill. pl. miškúosna ‘into forests’, is an innovation resulting from reanalysis of the acc. sg. *-n + *-ā́ → *-nā́. The neutralisation of the privative opposition inessive : illative originally comprised an area much larger than today’s and included the West Aukštaitian dialect. The starting point of this neutralisation was plural forms. This primary state of affairs has remained until the present day in East Aukštaitian in the north from the line Raguva-Ukmergė-Molėtai-Salakas, where inessive sg. and illative sg. are distinguished, but inessive pl. and illative pl. are not, due to apocope of the final vowel, i.e. píevos ‘on meadows’ (= iness. pl. píevose) alongside píevos ‘onto meadows’ (= ill. pl. píevosna) (Zinkevičius 1966: 201). In the privative opposition inessive : illative, the illative form derived from the IE accusative of direction is the marked member of the opposition.

Konrad Adenauer's government in the Federal Republic of Germany (FRG) engaged in a large-scale media campaign to create political consent for the FRG's integration into the West, a policy that rested to a large extent on rearmament and entry into the North Atlantic Treaty Organization. To counter public criticism of rearmament, the West German authorities used Mobilwerbung, a company that maintained a fleet of mobile film screening vans. Clandestinely financed by the government, Mobilwerbung brought government-commissioned films and political speakers into the FRG's remotest areas. Based on archival records on deployments in Lower Saxony and North Rhine-Westphalia, this article traces Mobilwerbung's role as a government unit that reacted dynamically to competing events. Through highly detailed reporting on audience reactions, Mobilwerbung served both as a public relations vehicle to foster consent and as an analytical tool that allowed the mapping of public sentiment regarding rearmament.

Nautilus is the only surviving genus whose members were numerous and widely dispersed in the oceans throughout the Jurassic and Miocene times. It represents the only living member from the Family Nautilidae and is often considered as a living fossil. Nautilus is found with high biodiversity in Ambon, Indonesia, and were in special cases even found in Bangka Belitung, far from their original habitat. This study aimed to understand the historical component of the habitat and distribution of Nautilus in Bangka Belitung and to determine the depth, temperature, current, and environmental heterogeneity relate to Nautilus. Nautilus samples were found in Bangka Belitung Seas nearby a crack region at 50–75 m deep while the optimal depth of the Nautilus was 150–300 m, depending on the local area. The locations in the Bangka Belitung Seas where Nautilus found have sea surface temperatures between 30-31°C and 27-28°C during the East Monsoon and the West Monsoon respectivelly. The implications of temperature as a limiting factor are fairly significant, as it restricts the upper limit of the living habitat to predictable depths, which vary both geographically and seasonally during the West Monsoon when surface temperatures approach habitable levels. Sea currents at the Bangka Belitung Seas move at 0–0.6 m.s-1 during the East Monsoon and speed up near the North Natuna Sea. During the West Monsoon, currents predominantly flow from the Natuna Sea to the Java Sea at 0–0.5 m.s-1. Large-scale deep-water currents and the effects of smaller currents on scent dispersal influence the directional movements of Nautilus.

Rain is deemed one of the most important climate elements. It must be given special attention for being the basis without which no kind of life in the world can be there. the aim of the study is to use Statistical models Downscaling (SDSM) where it is a universal model used to converting large scale output into a small scale that can be used to study impact at the local scale (Iraq)' to Forecasting cumulative annual rainfall for the next years where there are a few studies used this model in Iraq. Daily rainfall data from the Iraqi Meteorological Organization and Seismology (IMOS) (2007-2016) for the study areas (Baghdad, Karbala, Al-Hay, Mosul, Kirkuk, Khanaqin, Basra, Nasiriya, Diwaniya, and Rutba) is used to estimate the amount of rainfall by using SDSM. The model was used to estimate the rain values and then the results were compared with the actual values, the results were very close to each other. Also, the model used to predict the cumulative annual rainfall from (2017-2021), The result shows that the bigger amount of rainfall in the north region with (3821) mm and the lowest amount in the west region (665) mm, while middle region (1848) mm and south region (1828) mm.

AbstractIn October 2011 to December 2015, the Institute of Archaeology, Nanjing Museum conducted two terms of excavations to the Jiangzhuang Site located in the administrated areas of Xinghua and Dongtai Cities, Jiangsu Province. The main work was the large-scale uncovering of the settlement of the Liangzhu Culture located in the west zone of the site, the features recovered from which included burials, house foundations, ash pits, water wells, ash ditches, etc. In the cemetery of the Liangzhu Culture in the northeast of the west zone of the site, burials were densely arranged; most of the burials had burial receptacles, and the skeletons were well preserved, the burial positions of which included primary burials and secondary burials. The discovery and excavation of the settlement of Liangzhu Culture at Jiangzhuang Site revised the traditional viewpoint of the academic field that the north border of the Liangzhu Culture was limited by the Yangtze River and provided new materials for the comprehensive and in-depth researches on the civilization and society of the Liangzhu Culture. The large amount of human skeletons unearthed from the burials of the Liangzhu Culture will also effectively improve the indepth researches on the burial custom, social organization and relationship and racial attribution of the people of Liangzhu Culture.
