5-Year Plan 1/2. The degree I am seeking out and interested in is a degree in mechanical engineering. I am interested in this degree because I love mechanics and working with my hands. Mechanical engineers analyze problems‚ design mechanical devices to help with these problems‚ develop a prototype of the device and test it‚ and oversee the manufacturing of the device. I want to be in this field because of what they do‚ I want to build and work on machines. I would like to take the mechanical engineering

Mechanics of FX Forwards Screening Process Financial institutions screen potential buyers of FX forward contracts to protect themselves from counterparty default risk. Different institutions have different screening methods‚ but all methods try to measure the creditworthiness of the client. This involves analysis of the potential client’s current and historical financial position and credit history. It is worth noting that financial institutions often already have an ongoing relationship with

Waugh says that he thought to himself ‘that should happen on purpose’. Martin Waugh has now planned and captured over 100‚000 photographs of water in flight‚ taking thousands of pictures at a time‚ in the hope of capturing that one special shot. ‘Fluids in motion fascinate my senses’‚ he says‚ ‘they tickle some faint physical memory‚ like a scent evoking a forgotten mix of feelings’. He describes water collisions and splashes as sculptures that reflect a perfect balance of dynamic forces. Waugh says
