The aim of this paper is to evaluate the overall life cycle environmental impact an adiabatic compressed air energy storage (ACAES) system, which designed achieve best match between power production a photovoltaic (PV) plant and demand from final user. electrical small town, with maximum load about 10 MW, considered case study. ACAES system compressor-rated MW charging discharging times 24 h, r...

Future space ventures will likely require exploitation of near-Earth asteroid resources. Moreover, it can be envisaged that asteroids may host habitats in their interiors. In fact, a cavern inside an would natural radiation shield against cosmic and also serve as confined environment for storage mined material such water ice or other processed volatiles propellants. To this end, paper proposes ...

Preliminary geological investigations have been conducted to find suitable construction site and to assess engineering geological characteristics before detailed in situ investigation for large scale construction activities such as highway, railroad, subway or underground cavern constructions. The geological stability is a very important and critical factor for safe maintenance of structures an...

a 46- year–old man with pulmonary tuberculosis which had treated with ant tuberculosis drugs was referred to medical mycology laboratory, school of public health and institute of public health research for coughing and bloody sputum. chest x-ray revealed a cavern with a moveable mass in right apical lobe. direct examination of sputum showed wide septated dichotomous hyphae and aspergillus fumig...

In the early construction of cavern leaching in salt gas storages, inner tubing is often blocked, frequently leading to bending deformation phenomenon strings, which can result out-of-control cavity shapes. It difficult monitor stress, vibration, and morphological changes tube during a cavity. There are few research results this field at home abroad, they limited only preliminary explorations m...

Using underground space to store natural gas resources is an important means by which solve emergency peak shaving of gas. Rock salt storage widely recognized due its high-efficiency and environmental protection. Damage stress concentrations inside the cavern injection during withdrawal operations throughout facility life have always been among most safety issues. Therefore, accurate evaluation...
