Erosion Coast

A erosão costeira, que pode ser de decorrência natural ou por consequência de ações humanas, vem deixando suas marcas no litoral de Caucaia, destruindo residências, barracas de praia e outras estruturas urbanas. O objetivo deste estudo é avaliar a variação da linha de costa do município de Caucaia – CE, em um período de 10 anos, e categorizá-la a partir de classificação pré-definida a partir de estudos anteriores. A delimitação da linha de costa foi realizada a partir de imagens RapidEye e QuickBird tendo como base a linha de preamar média (LPM), esta determinação serviu para calcular suas taxas de variação a partir do parâmetro Linear Regression Rate (LRR). Os resultados levantados permitiram fazer análises particularizadas por praias. Desta forma verificou-se que as tendências erosivas se apresentam em 38% da costa, concentrando-se, no extremo leste do litoral e na sua região central. Já o trecho costeiro oeste apresentou taxas que indicam estabilidade e acreção.Palavras-chave: Linhas de costa; erosão costeira; Litoral de Caucaia. ABSTRACTThe Coastal erosion that may be due to natural causes or human actions has left its mark on the coast of Caucaia, destroying residences, beach tents and urban infrastructures (e.g.avenues). The objective of this study is to evaluate the shoreline variation of the municipality of Caucaia - CE over a period of 10 years and to categorize it from the classification applied by Esteves and Finkl (1998) and Luijendijk et al. (2018).The delimitation of the shoreline was made using a RapidEye and QuickBird images based on the average hightide line (LPM), this determination was used to calculate their rates of variation from the parameter Linear Regression Rate (LRR). In this way, it was verified that the erosive tendencies present in 38% of the coast, concentrating, mainly, between the central region and the more east end, in counterpoint, starting from the central area to the west are rates that indicate stability and accretion.Keywords: shoreline, coastal erosion, coast of Caucaia. RESUMENLa erosión costera que puede ser de naturaleza natural o como resultado de acciones humanas ha dejado su huella en la costa de Caucaia, destruyendo casas, cabañas de playa y otras estructuras urbanas. El objetivo de este estudio es evaluar la variación de la costa del municipio de Caucaia - CE, durante un período de 10 años, y clasificarla a partir de una clasificación predefinida de estudios anteriores. La delimitación de la costa se realizó a partir de imágenes RapidEye y QuickBird basadas en la línea media previa al casco (LPM), esta determinación se utilizó para calcular sus tasas de cambio a partir del parámetro Tasa de regresión lineal (LRR). Los resultados obtenidos permitieron realizar análisis individualizados por playas. Por lo tanto, se encontró que las tendencias de erosión están presentes en el 38% de la costa, concentrándose en el extremo este de la costa y en su región central. El tramo costero occidental mostró tasas que indican estabilidad y acreción.Palabras clave: costas; erosión costera; Costa del Caucaia.

Change Response

The most important function of the coastal setback is to minimize damage due to coastal erosion, climate change response, and sea-level rise. There are many directions and methods of researching and assessing coastal changes and coastal erosion. This study presents the results of the shoreline changes in the area from Son Tra (Da Nang City) to Cua Dai (Hoi An City), Central Vietnam based on remote sensing data from 1965 to 2019. Three methods are used to include End Point Ratio (EPR), Linear Regression Rate (LRR), and Weighted Linear Regression (WLR). The results show that the EPR method is effective when calculating the rate of shoreline changes only at two different times. For more objective and reliable calculation, it is necessary to assess the shoreline changes over time. Meanwhile, the LRR method was shown to be superior because all shoreline data were taken into account during the construction of the regression line. However, when there is much shoreline data with different reliability, the WLR method proved more superior because of limited objective errors. The results show that from 1965 to 2019, the coast of the Son Tra - Cua Dai area had quite complicated fluctuations, of which the northern area (Son Tra) tended to accretion, the central area tends to be alternate between accretion and erosion, while the south area (Cua Dai) is strong to very strong erosion. The coast with sudden changes is the Cua Dai area with the shoreline change envelope (SCE) reaching 512m. The results also allow us to divide the coast of the Son Tra - Cua Dai area into 30 segments. They are clustered into 8 groups with different levels of erosion and accretion. This is an important basis for the setback zone establishment in the study area.

Work Capability

This study's intended objective is to evaluate the effect of the work capability on the welfare of the apparatus and work facilities and its impact on the efficiency of the Mamuju police force in the province of West Sulawesi. This study uses a causal research design that illustrates a causal or causal association in the variables examined and used a quantitative approach. In this report, all the Mamuju Police staff, the West Sulawesi Province, were as many as 95. The sampling technique was a non?probability sampling process of systematic sampling, which implies that the samples were taken according to the order of the counted population members. Data collection was carried out by observation, distribution of questionnaires, interviews, and documentation. This review analyses and processes data with multiple linear regression using SPSS ver. 25. All the hypotheses suggested in this study are acceptable. The variables of the level of welfare and work facilities are critical variables that can influence staff's workability to enhance their performance. The story of welfare is necessary to inspire workers to function more efficiently; the more affluent the team, the more likely they are to increase their efficiency. Work facilities indicate that the types of facilities given by the company have facilitated an improvement in officers' efficiency, that the needs of the apparatus provide an appropriate standard of facilities, not just to facilitate their work, but also to promote satisfaction and ease of work.

The Many

The Limestone Massif of northwest Syria has the largest concentration of late antique churches in the world. All date from between the second half of the 4th century and the first decade of the 7th century and are remarkably consistent in their conformity to a recognizably ‘Syrian’ architectural style. Almost without exception they are apsed basilicas varying only in terms of size and the quality of decoration.This region was extensively surveyed in the 1950s by Georges Tchalenko, whose monumental three-volume study Villages antiques de la Syrie du nord remains the definitive work on the area. Of the many ecclesiastical buildings included in this survey Tchalenko identified a group of approximately 45 churches possessing a bema. The bema is a horseshoe-shaped structure in the nave that mirrors the curve of the apse. Entered via steps at the east end, it provided benches for the clergy and a pulpit at the west end that was used for scriptural expositions and homilies.

East End

Although the Rhætic beds are not exposed continuously along the eastern boundary of the Keuper outcrop, they have been proved at many points from the River Trent in the north on the Nottinghamshire border to Glen Parva in the south. South of this point there is so much drift, and borings within the Liassic outcrop have been so isolated or shallow, that there is a gap in our knowledge of the intervening ground between the last point and the Rugby district. The Countesthorpe boring, carried to a depth of over 600 feet, encountered Upper Keuper beneath the Drift, with no intervening Rhætics. Commencing in the north in the Gotham district the two outliers are capped above the Red Marl and Tea-green Marl with Rhætic beds, and Lower Lias Limestone (Ps. planorbe zone) above. At Ash Spinney at the south end of the southern outlier, and at the east end of Crownend Wood, Black Shales with Avicula contorta crop out; and on the west side septaria are seen. On the north-west side of the northern outlier at Cottager's Hill Protocardium phillipianum has been found in a well-section near the lane. Rhætic shales are seen in the shafts driven for gypsum works about Gotham.

Juda Hirsch Quastel, who contributed for more than 60 years to the growth of biochemistry, was born in Sheffield, in a room over his father’s rented sweet shop on the Ecclesall Road. The date was 2 October 1899, and his parents, Jonas and Flora (Itcovitz) Quastel, had lived in England for only a few years. They had emigrated separately from the city of Tamopol in eastern Galicia, which was then within the Austro-Hungarian Empire; it has since, after a period under Polish rule, become part of the Ukrainian Republic of the Soviet Union. Tamopol at the end of the 19th century was a city of some 30 000 and the centre of an agricultural district. Its inhabitants were ethnically mixed, but about half of them were Jews, many of whom under the relatively benevolent Austrian regime were fairly prosperous. Quastel used to recall how his father and grandfather had held the Emperor Franz Joseph in great respect. His grandfather, also Juda Hirsch (married to Yetta Rappoport), had at one time worked as a chemist in a brewery laboratory in Tamopol. The parents of the subject of this biography had been in commerce there, and were not poor; but today’s family members know little about the life of Jonas and Flora in Tamopol, or about the reasons that persuaded them, like many of their neighbours, to emigrate to the West. An uncle had already gone to England, and perhaps had encouraged them to follow because of the greater opportunities. In England they lived at first in London’s east end, where they worked in garment factories; but their move to Sheffield, and to Jonas’s modest entrepreneurship, had been completed in the late 1890s. It was there that Juda Hirsch and his four younger siblings (Charles, Doris, Hetty and Anne) were born.
