Abstract The article is devoted to a current problem of the need to increase the explosive safety of tanks. The paper analyzes the causes of explosions in tanks. Constructive solutions of existing stationary tank roofs are analyzed, including with an easily removable sheathing. The required areas of loss of containment of the tank roof are calculated depending on the type of flammable liquid. The dependence of the level of filling the oil product in the tank on the excess pressure during the explosion has been determined.

Individual, total, and combined root carbohydrate levels were greater in plants without fruit than in plants with fruit. Five major sugars (stachyose, raffinose, sucrose, glucose, and fructose) were found in the cantaloupe roots. Stachyose concentrations were higher than all the other sugars i

There was little adoption of CMU, especially by women farmers, because it was labor-intensive and it sacrificed banana production for up to 2 years.

Abstract:
Abstract Earthquake is one of the natural events which is part of NaTech events (Natural Hazard Triggering Technological Disasters), due to interaction between natural and industrial risks. Industrial plants employ cylindrical liquid tanks with floating roof for storage of volatile and flammable products. Damages due to earthquakes affecting tanks with floating roof can cause major accidents involving dangerous substances, like hazardous releases, fires and explosions, especially due to the convective motion of the fluid caused by seismic excitation. The aim of this work is to inform about the

Abstract:
Improving the survivability of a locomotive crew in the event of an accident has been a concern of the Federal Railroad Administration in the past decade. Locomotive crashes can injure the crew as well as deform the locomotive cab. Exiting from a deformed cab can be difficult, particularly for injured crewmembers. Egress becomes an even greater challenge if the locomotive is toppled. From an initial list of emergency egress concepts, the following three were chosen for further development: 1) hand/footholds to aid climbing inside a toppled locomotive, 2) roof-mounted escape hatch, and 3) exter

Heavy duty and aeroderivative gas turbines for power generation and mechanical drive are installed inside an enclosure that is thermally and acoustically insulated and is equipped with fire extinguishing systems. The enclosure is bolted on the gas turbine basement and is made of a steel frame that supports removable side panels, doors and roof sections. All the fire extinguishing systems, lubricating oil pipes and electrical systems are fitted inside the enclosure and release, together with the gas turbine, a large amount of heat that has to be dissipated to avoid overheating of the gas turbin

Abstract:
The objective of this project is to provide information about a problem material found in gas pipelines called "black powder". It is a mixture or a chemical compound of iron sulfides, iron oxides, dirt, sand, salts, chlorides, water, glycols, hydrocarbons and compressor oils, mill scale, or other materials. The most common constituents, iron compounds of sulfur or oxygen, are corrosion products. In addition to chemical formation, black powder can be formed by microbes normally found in gas pipelines. This material causes machinery, measurement, and pipeline maintenance problems. This research

Abstract:
The project was originally aimed at investigating and developing new efficient methods for cost effective removal of ammonia (NH₃) and hydrogen sulfide (H₂S) from Concentrated Animal Feeding Operations (CAFO), in particular broiler and laying houses (NH₃) and hog houses (H₂S). In both cases, the principal idea was to design and operate a dedicated air collection system that would be used for the treatment of the gases, and that would work independently from the general ventilation system. The advantages envisaged: (1) if collected at a point close to the source of generation, pollutants would
