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.

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.

AbstractKirschsteinite (mainly CaFeSiO4), in association with forsterite-fayalite solid solutions, melilite, clinopyroxene, leucite, nepheline and several minor phases, is reported for the first time in the 290 ka Capo di Bove melilite-leucitite lava flow of the Alban Hills volcanic complex (Italy). Kirschsteinite appears very late in the crystallization sequence, as indicated by textural and chemical evidence (Mg# ≈ 25). It shows significant solid solution towards fayalite, and is found with groundmass phases indicating a relatively low-temperature melt composition more silica-undersaturated than phonolite (i.e. devoid of alkali feldspar). This clearly points to the very silica-undersaturated nature of almost all the Alban Hills volcanic rocks.

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.

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.

AbstractIn this paper are presented the studies of the paint materials and the technique used in 18th century wall paintings, originated from the orthodox church of St Athanasius, in the city of Maschopolis, a flourishing economical and cultural center, in Albania. The church was painted in 1745 by Konstantinos and Athanasios Zografi, and during the last years, restoration activities are being performed at the church. Samples that included plasters and pigments of different colors were collected from important points of the wall paintings. Additionally, as some parts of the wall-paintings were over-painted, the analysis was extended to the compositional characterization of these areas. The identification of the used materials was done by using complementary analytical methods such as Optical Microscopy, Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM-EDS) and X-ray fluorescence (TXRF).The presence of calcite in almost all the pigments is indicative for the use of the fresco technique at the studied areas, while the detection of gypsum and calcium oxalate, indicates an environmental degradation along with a biodegradation. Common pigments used in this area at 15-16th centuries, such as cinnabar, green earth, manganese oxide, carbon black and calcite were identified.

Introduction: In Japan, the number of automated external defibrillators (AEDs) placed in public areas has climbed up to the estimated 530,000. We reported previously that a half of out-of-hospital cardiac arrests occurred within 100 m from a public AED in urban areas. However, shocks for defibrillation were given to less than 15% of those patients. The objectives of this study was to identify the limiting factors against the use of AEDs by bystanders. Methods: A prospective survey on out-of-hospital cardiac arrest was conducted in the city of Osaka (Dec 2016 through Mar 2017) and the city of Nagoya (Dec 2016 through Nov 2017) searching for patient demographics and AED settings including; absence/presence of a public AED on the scene, attachment of AED pads, delivery of shocks before the time of EMS arrival. Results: Of 558 cases of cardiac arrest registered during the survey period, an AED had already been delivered at the patient side by the time of EMS arrival in 92 case (16.5%). Of those, pads had been attached in 89 cased (96.7%). Shocks had been advised in 35 cases (39.3%) and to all but one of those cases at least 1 shock had been given by the bystanders. There were no statistically significant differences between the groups of cases with and without AEDs at the patient side regarding the patient age (65 years [IQR: 48-74] vs 63 years [IQR49-75], p=0.84), gender (p=0.68) and the time from call to EMS arrival (7 min [IQR: 6-9] vs 7 min [IQR: 6-9], p=0.74). Cases occurring indoors had more chances of AEDs being delivered on the patient side than cases occurring outdoors (24.0% vs 7.8%, p<0.001). Conclusions: Our study indicates that once an AED is delivered at the patient side, pads are successfully attached and shocks are given if indicated in almost all cases. This suggests that finding and delivering an AED onto the patient side are the limiting factors against the use of AEDs by bystanders. In order to popularize the use of AEDs by bystanders, informing people with AED placement and clear direction to the AED location seem to be the key steps.

ABSTRACT The Montreal Battery of Evaluation of Amusia (MBEA) is a battery of tests that assesses six music processing components: scale, contour, interval, rhythm, metric, and music memory. The present study sought to verify the psychometric characteristics of the MBEA in a sample of 150 adolescents aged 14-18 years in the city of Belo Horizonte, Minas Gerais, Brazil, and to develop specific norms for this population. We used statistical procedures that explored the dimensional structure of the MBEA and its items, evaluating their adequacy from empirical data, verifying their reliability, and providing evidence of validity. The results for the difficult levels for each test indicated a trend toward higher scores, corroborating previous studies. From the analysis of the criterion groups, almost all of the items were considered discriminatory. The global score of the MBEA was shown to be valid and reliable (r K-R20=0.896) for assessing the musical ability of normal teenagers. Based on the analysis of the items, we proposed a short version of the MBEA. Further studies with larger samples and amusic individuals are necessary to provide evidence of the validity of the MBEA in the Brazilian milieu. The present study brings to the Brazilian context a tool for diagnosing deficits in musical skills and will serve as a basis for comparisons with single case studies and studies of populations with specific neuropsychological syndromes.

The paper examined and brought to the fore the typical characteristic of urban and peri-urban farmers in Freetown and Bo communities which serves as major source of supply of agricultural products into the cities’ markets. The social and environmental aspect and perception of producers involved in urban and peri-urban agriculture was examined. Descriptive statistics and pictograms were used to analyze and present the data. Results indicate that 56.34% never went to formal school and mostly dominated by women, showing that farming became the alternative means of livelihood support for those groups. Crops grown are purely influenced by market orientation—demand and cost, as is evident in Gloucester (lettuce, cabbage and spring onions). Potato leaves were commonly grown in almost all communities, reason being that it serves as common/major sauce/vegetable cooked in every household in Sierra Leone. Maize and rice were featured in Ogoo farm—government supervised land set aside purposely for growing crops to supply the city. Findings also revealed that majority of the farmers are resource poor, judging from calculation about their monthly income earning and available household assets and amenities. About 70.4% of the lands the farmers grow their crops on is leased for production. Except for Gloucester community, when costs of production will be summed, minimal benefit seem to be realized from the farming activities. Even though some of these farmers are engaged in organization, many have limited access to micro financial organization that would probably loan them money to upscale production.
