Abstract The system of seabed Cone Penetration Test (CPT) is a kind equipment for offshore investigations. Seabed CPT used to assess multiple physical properties marine sediments. Constant-rate penetration mechanism the core part CPT, which adopts dual-cylinder drive penetrate probe rod into seafloor sediments at constant speed (2cm/s). At present, domestic and its almost all rely on imports. I...

shear wave velocity is a basic engineering tool required to define dynamic properties of soils. in many instances it may be preferable to determine vs indirectly by common in-situ tests, such as the standard penetration test. many empirical correlations based on the standard penetration test are broadly classified as regression techniques. however, no rigorous procedure has been published for c...

In many cases grid extension is often highly costly and unlikely to happen – even in the mediumto long-term. In these scenarios, mini-grids (MG) could provide an ideal intermediary solution, especially for small towns or large villages where enough electricity can be generated to power household use, as well as local businesses. MGs provide centralized electricity generation at local level usin...

background: reusing orthodontic mini-screws would reduce treatment cost and lead to more use of mini-screws and improvement of orthodontic treatments. this study has assessed the effects of reprocessing and reusing the titanium mini-screws on their maximum insertion, removal and fracture torque (ft). materials and methods: in this experimental study, 20 titanium mini-screws (1.6-mm × 8-mm) were...
