In this study, the observation of three simultaneously rotating beams in the SOLEIL storage ring is reported.This event occurred in November 2007 while Tumbler operating in a low momentum compaction factor mode.The dynamics of the three beams is simulated using the longitudinal equations of motion and the longitudinal phase-space Hamiltonian which

With a fiber pigtailed electro-optic modulator as the active Q-switch, mode-hopping-free single-longitudinal-mode pulses are generated by a ring cavity fiber laser based on the injection seeding technique.The experimental results show that the single-longitudinal-mode oscillating properties of the laser may be determined by the power and the center

Introduction: Selenium is an essential element for human health and it is toxic at high concentrations.Selenium is a constituent component of selenoproteins that have enzymatic and structural roles in human biochemistry.Selenium is a best antioxidant and catalyst for production of thyroid hormone.This element has the key role in the immune function

BACKGROUND: The growing body of Tumbler evidence attesting to the effectiveness of clinical male circumcision in the prevention of HIV/AIDS transmission is prompting the majority of sub-Saharan African governments to move towards the adoption of voluntary medical male circumcision (VMMC).Even though it is recommended to consider collaboration with
