ABSTRACT The rocks and sediments of the region have been divided into eight units: metamorphic rocks of pre-Mesozoic age, composed of mica schists; volcanic rocks, columnar andesites, tentatively assigned to the Tertiary, that outcrop in a small area to the west of Castro; fluvioglacial deposits, uncemented sands and gravels that in almost all cases overlie three terraces of Pleistocene age that are indicated on the map as morphologic units; slope deposits, friable hybrid material neither classified nor consolidated, that cover one of the most dangerous areas in which to construct; beach deposits—unconsolidated coastal sediments; unconsolidated alluvial sediments distributed in the beds of rivers and in the river deltas presently in formation; and deposits of artificial fill, gravels, sands, bricks, trash, etc. Damage to structures is clearly related to the geology. In areas of artificial fill and of slope deposits, catastrophic destruction was caused almost exclusively by geologic and morphologic factors. Some areas with a favorable morphology, such as the intermediate and high terraces, are formed of sound material, such as metamorphic rocks, and had little or no damage.

The purpose of the work is to determine the state of study and the prospects for further research on the vertebrate animals remains from the Mesozoic deposits of the Lugansk region. To achieve this goal, collection and generalization of information on the locations of vertebral remains among the Mesozoic deposits of Lugansk region were made. Despite the considerable amount of findings of various groups of Mesozoic vertebrates remains in the Donets Basin territories adjoining them, their systematic and purposeful study, unfortunately, was not conducted in Lugansk region, although indications of the findings of the Mesozoic vertebrates remains in the Luhansk region occur quite often. As a result of the processing of published materials and preliminary interpretation of field observations, a list of 20 sites located mainly on the right bank of the Siversky Donets within the Lugansk region is compiled. Almost all the places are confined to the Upper Cretaceous deposits, much less – to the basal layers of the Paleogene and only one to the Triassic. The vast majority of the locations of the Upper Cretaceous are confined to the area in contact with an array of coal deposits (the so-called "open Carboniferous"). Outwards from it, the rocks are more open-sea and they drastically reduce the diversity of the fossil fauna. Therefore, outlining the range of promising areas regarding finding vertebrate animals remains one should be aware of the above-mentioned pattern of their placement. Triassic deposits of the Donbas are not at all investigated for finding the remains of vertebrates, although their potential is very significant. Nevertheless, due to the small area of the Triassic deposits outcrop in the Lugansk region, searches need to be directed to the west – in the Donetsk and Kharkiv regions.

ABSTRACT The rocks and sediments of Ancud and suburbs have been grouped into five units. The volcanic rocks are included in a unit, or geologic formation, called the Volcanic Complex of Ancud. The complex is tentatively considered to be Tertiary or Quaternary in age and is formed of andesites, welded tuffs, breccias and agglomerates that outcrop in almost all the hilly region, the coast, and the surroundings of Ancud. In some sections terraces have been formed over the rocks of this complex. The outcrops of the complex are weathered to a reddish-yellow material easily disaggregated with a hammer. Terrace deposits are observed in some of these terraces to be poorly cemented gravel, clay, and limonite. The alluvial deposits are distributed in the stream courses of Rio Pudeto and in Matadero and La Toma Creeks; they are composed of unconsolidated gravels, sands, silts, and clays. Beach deposits are observed along the length of the coast, and are principally a poorly consolidated aggregate of gravels and sands. Artificial fill is deposited in the coastal zone; its materials are gravels, sands, silts, bricks, wood, debris, etc. There is a relation between the geology and the damage produced by the earthquakes in works of man. The areas underlain by the Volcanic Complex of Ancud are those that best resisted the effects of the earthquakes, and these are suggested as the most suitable for the expansion of the city. The most serious damage from the earthquakes are observed over the alluvial deposits and at the edges of one of the terraces. The last observation suggests that these areas are unfavorable, and that any future plans for construction over these should be preceded by a study of soil mechanics. It is indicated that the geographic position of Ancud with respect to tidal waves is unfavorable. It is suggested that the construction be prohibited near the sea, and that absolutely indispensible coastal buildings should be carefully studied with regard to a possible repetition of the phenomena.

Since 1997, we watched the birds of prey that lived in the Samara city, and found that the most numerous and widespread in these conditions is a Sparrow hawk. During this time, the number of this type birds of increase. Now it is we value it more than 50 pairs. In urban environments, many hawks inhabit the typical places for them - woodland area of more than 1 hectare, where a lot of young trees. Not only the natural forests but artificial too. In the last 5-7 years there has been a tendency to breed hawks in atypical for their groves with a very small area in the densely populated areas of the city. In 2016, we found Sparrow hawks nest in a grove near the geographical center of the Samara city. Area trees no more than 0,5 hectares, it is 50 meters from the road, and 5 meters from the curb. But here the hawks successfully grow brood. 3 young hawks are haking in the and of nesting (2 females and 1 male). Thus, despite the active cultivation and development of forest parks and vacant lots in the Samara city, carried out in recent years, sparrow hawks, are here in the first place, the optimum feeding conditions, showing almost all adaptive capacity to adjust to changing conditions.

Garcinia kola usually referred to as "bitter cola" is a tree found in the rainforests. Many studies have revealed the properties of its seeds: antimicrobial, analgesic, anti-inflammatory, hepato-protective, antidiabetic, antioxidant. In the West Region of Cameroon these seeds are mainly used against nausea and vomiting; unfortunately, the generalization or the widening of the use of these seeds encounters some problems: the production is seasonal (June to September), the plant only grows in a small area (the departments of Moungo and Mbam and Inougou), the long storage of the seeds is not possible (they harden quickly and become unfit for consumption). The non-toxicity of these seeds having already been demonstrated by Udenze et al in 2012, in this study we wanted to develop a galenic form that is easy to produce and likely to help better use this resource by circumventing these difficulties. Garcinia kola seeds purchased in the city of Bafia, were cleaned, crushed and dried for 2 days at the temperature of 30°C and finally ground. The powder obtained was used to prepare capsules. The powder, calibrated through a 125 sieve, was homogeneous and had a residual humidity of 4%; its flavonoid content was 28 mg quercetin equivalent per gram. The capsules contained 400 mg of seed powder and titrated 3 mg quercetin equivalent of flavonoids per unit. They have responded favorably to the pharmacotechnical tests recommended by the European Pharmacopoeia 5th edition and appear to be able to allow the use of Garcinia kola seeds everywhere and in any season.

Recent advances in transmission electron microscopy (TEM) and analytical electron microscopy (AEM) have led to many new insights into the structural and chemical characteristics of very finegrained, optically homogeneous mineral aggregates in sedimentary and very low-grade metamorphic rocks. Chemical compositions obtained by electron microprobe analysis (EMPA) on such materials have been shown by TEM/AEM to result from beam overlap on contaminant phases on a scale below resolution of EMPA, which in turn can lead to errors in interpretation and determination of formation conditions. Here we present an in-depth analysis of the relation between AEM and EMPA data, which leads also to the definition of new mineral phases, and demonstrate the resolution power of AEM relative to EMPA in investigations of very fine-grained mineral aggregates in sedimentary and very low-grade metamorphic rocks.Celadonite, having end-member composition KMgFe3+Si4O10(OH)2, and with minor substitution of Fe2+ for Mg and Al for Fe3+ on octahedral sites, is a fine-grained mica widespread in volcanic rocks and volcaniclastic sediments which have undergone low-temperature alteration in the oceanic crust and in burial metamorphic sequences.

The status of tafsīr and Qur'anic studies in the Islamic Republic of Iran has changed significantly during recent decades. The essay provides an overview of the state of Qur'anic studies in Iran today, aiming to examine the extent of the impact of studies by Western scholars on Iranian academic circles during the last three decades and the relationship between them. As in most Islamic countries, the major bulk of academic activity in Iran in this field used to be undertaken by the traditional ʿulamāʾ; however, since the beginning of the twentieth century and the establishment of universities and other academic institutions in the Islamic world, there has been increasing diversity and development. After the Islamic Revolution, many gradual changes in the structure and approach of centres of religious learning and universities have occurred. Contemporary advancements in modern sciences and communications technologies have gradually brought the institutions engaged in the study of human sciences to confront the new context. As a result, the traditional Shīʿī centres of learning, which until 50 years ago devoted themselves exclusively to the study of Islamic law and jurisprudence, today pay attention to the teaching of foreign languages, Qur'anic sciences and exegesis, including Western studies about the Qur'an, to a certain extent, and recognise the importance of almost all of the human sciences of the West.

Accounting education is taught in some private universities has impressed as stagnant knowledge, mechanical, and oriented material that causes a lot of students in general become saturated in the learning process. In Indonesia at several universities, almost all accounting courses little or no charge to enter the motivation, creativity, and mentality in the accounting curriculum-based motivation, creativity, and mentality can only he done well when formulated in a more complete firm of the curriculum. Therefore, this study examines the effect of motivation, creativity and mentality in accounting education to obtain empirical evidence. In this study using primary data obtained through questionnaires from a list of questions posed to accounting students in private universities in the city of Padang. The sample in this study was conducted with a purposive sampling technique where the sampling method was based on certain criteria, namely : involving student participants who majored in accounting class of 2010, 2011, and 2012 who had studied the sciences and overall accounting associated with accounting. Testing the hypothesis of this research is conducted with multiple regression analysis. The first hypothesis testing results found that motivation does not significantly influence accounting education in private universities Padang. The second hypothesis testing results found that creativity significantly influence accounting education in private universities Padang. The third hypothesis testing results found that significantly influence the mentality of accounting education in private universities Padang.

Foundation myths are a crucial component of many Greek cities’ identities. But the mythic tradition also represents many cities and their spaces before they were cities at all. This study examines three of these ‘prefoundational’ narratives: stories of cities-before-cities that prepare, configure, or reconfigure, in a conceptual sense, the mythic ground for foundation. ‘Prefoundational’ myths vary in both form and function. Thebes, before it was Thebes, is represented as a trackless and unfortified backwater. Croton, like many Greek cities in south Italy, credited Heracles with a kind of ‘prefounding’, accomplished on his journey from the West back to central Greece. And the Athenian acropolis was the object of a quarrel between Athena and Poseidon, the results of which gave the city its name and permanently marked its topography. In each case, ‘prefoundational’ myth plays a crucial role in representing ideology, identity, and civic topography.

On a warm summer afternoon in 1561, Calvin’s chief editor donned a heavy stole, thick robes, and a gleaming tiara and proceeded to strut and fret his hour upon the stage in a comedy of his own devising. For little more than a century, Christians in the West had celebrated on August 6th Christ’s Transfiguration as the son of God in shining robes. But on this Sunday in Geneva, the city council, consistory, and an audience fresh from having attended edifying sermons at morning service gathered to applaud the transfiguration of the learned Conrad Badius into the title role of ...

Thucydides reports that the Phoenicians were present throughout Sicily and traded with the Sicels. A tangible Phoenician presence in Sicily, as expressed by pottery, is attested only at the end of the eighth century bce. The earliest hypothetical Phoenician settlements of Solunt and Panormus are still almost unknown. This earliest phase is associated in particular with the city of Motya, where pottery and a few other finds testify to it. The Punic phase of the island is much clearer, with almost all indications coming from Motya and Selinus, which were not built over in Roman times. The Pfeilertempel, as emerged from Motya, could be regarded as the prototype for the Phoenician temple in Sicily. In turn, it is possible to recognize a characteristic type of temple of Punic Sicily, as particularly shown at Selinus, These shrines, as well as other elements of the Punic settlements like the houses, the fortifications, or the necropoleis, in particular from the fourth century bce onwards, are evidence of an advanced degree of Hellenization, framed within a Mediterranean koine.
