In October 2017, it was acquired by Wood Group.It was focused on the Oil, Gas & Chemicals, Mining, Power & Process and Environment & Infrastructure markets, with offices in over 55 countries worldwide. Roughly a third of its turnover came from Europe, half from North America and 12% from the rest of the world.Amec Foster Wheeler shares were publicly traded on the London Stock Exchange and its American Depositary Shares were traded on the New York Stock Exchange.
Hyperthyroidism directly affects the cardiovascular system, altering the heart's normal function and leading to high cardiovascular mortality. Excess thyroid hormones are associated with significantly increased risk and prevalence of cardiac arrhythmias, particularly atrial fibrillation (AF). This article reviewed the hemodynamic changes and the risk of cardiac arrhythmias, including atrial and ventricular arrhythmias associated with hyperthyroidism. It has also discussed the multi-level pathophysiology of thyrotoxic AF, sinus tachycardia, and different treatment modalities such as anti-thyroid drugs, beta-blockers, and the role of cardioversion and catheter ablation. This article has explored different studies that have concluded that AF and sinus tachycardia are the most common arrhythmias associated with thyrotoxicosis.
O reúso de águas a partir do aproveitamento do efluente tratado em Estações de Tratamento de Esgoto Doméstico, já é praticado em alguns países e no Brasil, porém carece ainda da quebra de alguns paradigmas associados a reação natural à água de reúso pelo sentimento de não se estar usando água tratada. Embora existam alguns exemplos de reúso não potável planejado em zonas rurais, ainda há um largo caminho a percorrer nas áreas urbanas. No entanto a condição de escassez hídrica motiva as regiões áridas e semiáridas do Brasil, juntamente com áreas urbanas que hoje possuem elevados consumos, a se transformarem em áreas potenciais para utilização de projetos de reúso, surgindo como oportunidades para implantar novas tecnologias. Assim, com base nos dados obtidos sobre as Estações de Tratamento existentes e a serem implantadas na cidade de Maceió, como também considerando as características de potenciais usos para Reúso Não Potável Industrial e Reúso Potável Indireto, foram feitos estudos que buscaram a partir deste trabalho, identificar Estações de Tratamento de Esgotos e usuários na região metropolitana de Maceió, capazes de utilizarem a água de reúso para vários fins. Os resultados mostraram que há um potencial de reúso de cerca de 60% do Volume Distribuído médio mensal para Maceió tomando 2016 como ano base.
Experimental studies were undertaken to investigate the vertical load versus displacement behavior of single model piles in sand (i.e., Unimin 7030 sand) under both saturated and unsaturated conditions. Stainless steel model piles with three different diameters (i.e., 19.25, 31.75, and 38.3 mm) with a length of 350 mm were used to conduct the pile load tests. Semiempirical methods were proposed to successfully predict the variation of end-and shaftbearing capacities of single piles with respect to matric suction by modifying three conventional end-bearing capacity equations (Terzaghi 1943; Hansen 1970; Janbu 1976) and the beta-method (Burland 1973), respectively. In addition, finite element analyses were also carried out to simulate vertical load versus settlement behaviors of model pile tests using a commercial finite element software, SIGMA/W (GeoStudio 2007).
