made + of/from/out of what is the different between that expressions? made of / made from/ made out of could you please give some examples? thanks for your help!

Please correct this An offshore oil platform is a large structure, attached to the Bed Sea, provided with all the facilities and devices required in drilling wells, extracting and processing different fossil fuels, such as oil or natural gas. Some of the most dangerous jobs are oil industry and offshore stations. In consequence, working in an offshore oil platform is plenty of hazards, and any staff has to be really careful to avoid and prevent accidents. The main hazards are the bad conditions outside, such as cold, cloudy, rainy or windy weather; and the uses of toxic and flammable fluids. In order to prevent accidents is important to ensure that the staff avoids any unsafe situation. To prevent to fall down from the base to the water, a safe net and hand railing should be installed, furthermore, it is recommended that any staff working outside, when bad weather conditions, wears a harness and lifejacket. To prevent for fires, and toxic liquids or fumes, it is required to install a large system of detectors to monitoring the air quality and temperature in the whole station, paying special attention to small and confined spaces. The system should include alarms, ventilation to work in case of accident. Thanks for your corrections forehand!

Geothermal Energy. Please correct it This text is supposed to be the transcription of an oral presentation, so I'm sorry if it is a mess and you don't understand it. However, I'd be please if you could correct any mistake. Thanks forehand. Hello, I'll talk to you about Geothermal Energy, also, I'll focus on applications in HVAC and DHW. Geothermal Energy is the thermal energy generated and stored in the Earth. We can see here a classification of the different geothermal sources by temperature and applications for each one. However, we're focusing on very low temperature source, since it is the only one we can find easily in Spain. Geothermal Power Plants are not very important, as there are not more than 10 GB installed. However, it is important in countries like Iceland, El Salvador or the Philippines. There are two different kinds of Geothermal Power Plants. Here we can see that we use the dry steam from the ground directly. When the ground cannot supply dry steam a heat exchanger is required, as it is shown in the picture. When we don't have neither a working fluid nor enough temperature, we have to work with brine and a geothermal heat pump to increase o decrease the temperature. I'll explain briefly the different configurations exist in ground heat exchangers. The ground loops can be open or closed. The most common used in Spain is the closed one, since it is not easy to find underground water. Furthermore, if we compared vertical and horizontal loops, we'd find that even vertical one is much more expensive, it is commonly used, as horizontal one has significant handicaps. You might be wondering if a geothermal heat pump can be used in any kind of building. Let me say that it is. I have differents examples to show you that. A bank's new headquarters, a block of flats and a detached house. The three projects in Madrid, by the way.

Please correct it. Engineering design The main topic of the video is how has changed the engineering design in the last century. It explains that engineering design is influenced by politics, wars and great achievement. Being the main languages using in engineering design publications, the speaker examines the different tents of different languages from the First World War to nowadays. In 1917, due to the First War War the number of publications drop, however, few years later, after the Russian Civil War finished, engineering publications increased in that country. During the Second World War, in the most of countries the publications descended, but in Japan. After the first nuclear weapon demonstration, and also because of the space race, the publications in Russia were raised. In the last years, new topics has become important, e.g. Final Element Methods. At the end, the speaker says that the most important language nowadays is English, mainly in business and technology.
