The application of the lean manufacturing strategy aims to reduce waste and increase productivity organization in which it is applied; however, Peru many companies metal-mechanical industry do not know how implement it. objective research tools washing machines. We implemented 5S time route waste, Kanban standardize production based on demand lead time, as well use MRPII for its execution. In a...

Silicon micromachined terahertz passive components such as silicon washers, waveguide blocks for W-band (75-110 GHz) power amplifiers, and waveguides for 325-500 GHz band have been designed, microfabricated, and characterized. Based on these results, an integrated 600 GHz silicon micromachined RadiometerOn-a-Chip (ROC) has been demonstrated for the first time. It reduced in mass by an order of ...

The surgical treatment for proximal humeral fractures is challenging, especially in patients with osteoporosis. Locking plates and intramedullary nails have been widely used with satisfactory results, but previously reported complications have not been substantially reduced. Several authors have emphasized the importance of maintaining soft tissues around the proximal humerus with respect to li...

This study compared the stiffness (K), yield load (YL), and slippage (SL) of six tibial fixation methods. These properties were determined from load-to-failure and cyclic tests of double-looped tendon grafts fixed to both animal and young human tissue. Tandem washers (K = 259 N/mm, YL = 1159 N, SL = 0.5 mm) and the Washerloc (K = 248 N/mm, YL = 905 N, SL = 2.0 mm) were the two best fixations. A...

The results of proximal humeral replacement following trauma are substantially worse than for osteoarthritis or rheumatoid arthritis. The stable reattachment of the lesser and greater tuberosity fragments to the rotator cuff and the restoration of shoulder biomechanics are difficult. In 1992 we developed a prosthesis designed to improve fixation of the tuberosity fragments in comminuted fractur...
