The combination of ticarcillin and clavulanic acid (Timentin) was used in a nonrandomized open study in 28 patients with severe nosocomial infections. The infections were polymicrobial in 19 cases. Ten patients were bacteraemic and all were severely ill, receiving mechanical ventilation and with at least one organ system failure. Seventeen patients were(More)
We report the possibility of using nonuniform tapered microstructured optical fiber (NTMOF) to reduce the overall coupling loss from an upstream MOF to a downstream fiber being another MOF with different geometry. The NTMOF is supposed to be drawn at the output end of the upstream MOF, with no coupling loss between the two. The propagation loss along the(More)
We have experimentally demonstrated square pulses emission from a co-doped Er:Yb double-clad fiber laser operating in anomalous dispersion DSR regime using the nonlinear polarization evolution technique. Stable mode-locked pulses have a repetition rate of 373 kHz with 2.27 µJ energy per pulse under a pumping power of 30 W in cavity. With the increase of(More)
Based on the control of the linear losses of the cavity, we demonstrate the possibility to achieve filterless laser emission above 1.6 μm, from a C-band double-clad Er:Yb doped fiber amplifier. The concept is validated in both continuous wave and mode-locked regimes, using a figure-of-eight geometry. A unidirectional ring cavity is also tested in the(More)
We propose a new technique to selectively excite the fundamental mode in a few mode fiber (FMF). This method of excitation is made from a single mode fiber (SMF) which is inserted facing the FMF into an air-silica microstructured cane before the assembly is adiabatically tapered. We study theoretically and numerically this method by calculating the(More)
We demonstrate experimentally a double-clad Er:Yb co-doped dual amplifier passive mode-locked figure-of-eight fiber laser that generates high energy, width, and amplitude tunable dissipative soliton resonance square pulses. In our laser system, each loop contains an amplifier that controls a characteristic of the output pulse. The amplitude and width of the(More)
We have observed and demonstrated the linear and non linear parameters dependent optimum power and repetition rates of a hybrid - type actively and passively mode locked laser pulses in an erbium doped fiber laser of the figure of eight geometry by using a nonlinear amplifying loop mirror (NALM) totally made up of microstructured optical fiber MOF as a(More)
Based on the dissipative soliton resonance occurring in highly anomalous dispersion regime, we have demonstrated the emission of highly energetic square-wave pulses from the Er:Yb doped double clad fiber laser passively mode-locked through nonlinear polarization evolution. In contrast with the classical soliton regime, when the pumping power increases the(More)
This communication allows the implementation of an internet of things solution for smart home. It uses the ZigBee network for communication within the home between the gateway and the different intelligent nodes. A PHP application has been developed enabling the user to control remotely his equipment locally or from the Internet. The house implemented is(More)
