Measuring Optimal Length of the Amplifying Fiber in Different Working Conditions of the Amplifier
Advances in Electrical and Electronic Engineering, 2014 The aim of this article is to highlight possible unwanted behaviour of an EDFA optical amplifier during temperature changes. After a brief introduction dealing with amplifiers and doped fibers in general we focus on the assembly of our own EDFA amplifier

Pan African Medical Journal, 2014 64-year-old man farmar was admitted to our department with low back pain radiating to the lower extremities. He had a history of febrile illness and loss of appetite 2 years before admission. Four months after the start of the febrile illness, the patient started to complain of backache and spinal movements were restricted and painful.
