Qat or Khat Scientific Name: Catha Edulis 05/04/2023 Qat (also known as khat or Catha edulis) is a flowering plant native to East Africa and the Arabian Peninsula. The plant's leaves contain psychoactive compounds, including cathinone and cathine, which produce stimulant effects when chewed or ingested. Qat has a long history of use in traditional cultural practices and social gatherings in East Africa and Yemen, where it is consumed by chewing the leaves or brewing them into a tea. The effects of qat use are said to include increased energy, euphoria, and a sense of well-being, as well as reduced appetite and fatigue. However, qat use is also associated with a number of negative health effects. Prolonged use can lead to dependence and addiction, as well as increased risk of cardiovascular disease, gastrointestinal problems, and mental health issues such as anxiety and depression. The legal status of qat varies depending on the country or region. In some places, such as Ethiopia an...
Edited by Medo Hamdani Date: 10/05/2023 Petroleum geology and geophysics focus on the provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behaviour of oil, water and gas within porous rock at very high pressure. Petroleum engineering requires a good knowledge of many other related disciplines, such as Geophysics [[1][3]] refers to the use of physics principles to study the earth's properties and structure, including the subsurface. Geophysics is used in petroleum engineering to locate and characterize reservoirs, monitor and optimize production, and study the surrounding geology. Common geophysical techniques include seismic imaging, gravity and magnetic surveys, and well logging. Understanding the results of geophysical surveys is essential for effective reservoir management and optimization. Petroleum geology [[1][2]...
