In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...

Using a rotating vitreous carbon disk electrode, the kinetic parameters for chlorine reduction in an AlCl3 KCl-NaC1 (57.5-12.5-30 mol g%) melt were determined. It was found that the reduction of chlorine occurs according to the paths: C1 2 + e C1 + Clad s ads with the first step being most probably rate determining. The apparent exchange currents were (1 ± 0.15)10 -4A/cm 2 at 130 °C and (2.1 ± ...

BACKGROUND The role of CD4+CD25highCD127- T-reg cells in solid-organ Transplant (Tx) acceptance has been extensively studied. In previous studies on kidney and liver recipients, peripheral T-reg cell counts were associated to graft survival, while in lung Tx, there is limited evidence for similar findings. This study aims to analyze long term peripheral kinetics of T-reg-cells in a cohort of lu...

PurposeSurvival after lung transplantation (LT) is hampered by the development of chronic allograft dysfunction (CLAD). There no treatment available to reverse CLAD once diagnosed, but early intervention could modify progressive function decline. Thus, biomarkers are need for detection CLAD. High levels donor derived cell-free DNA (ddcfDNA) have been described precede acute cellar rejection and...

AIM To assess the prevalence of vitamin D deficiency in burka-clad pregnant women and to study feto-maternal outcome in these women. METHODS 200 pregnant burka-clad women of 18-40-year age group irrespective of the period of gestation were recruited from the ANC OPD/ward of Kasturba hospital, and their vitamin D levels were estimated. Patients were categorized into vitamin D deficient, vitami...

OBJECTIVE There is growing interest in using closed-loop anesthetic delivery (CLAD) systems to automate control of brain states (sedation, unconsciousness and antinociception) in patients receiving anesthesia care. The accuracy and reliability of these systems can be improved by using as control signals electroencephalogram (EEG) markers for which the neurophysiological links to the anesthetic-...

The paper reviews the properties of periodic and guiding structures which now play an important part in the operation of components, antennas, electron tubes and low-noise amplifiers. An account is first given of dispersive propagation in periodic-loaded lines, showing how the frequency characteristic breaks into pass and stop bands. The formation of forwardand backward-space harmonics and the ...

Chronic lung allograft dysfunction (CLAD) is, in one sense, a term without a true consensus definition, although its common usage in the field of lung transplantation implies a base understanding throughout the community that it describes a lung allograft that does not work (well) [1]. There appears to be general agreement that CLAD most commonly occurs in a time-dependent fashion after transpl...

The laser parasitic oscillations in active media under high pumping condition limit the gain of a high power amplifier system. This problem occurs due to existence of closed optical paths by internal reflections of active medium or systems. This problem can be overcome by eliminating the internal reflections by making rough surface, grooves, or antireflection coating or using index matching flu...

PurposeChronic lung allograft dysfunction (CLAD) is the leading long-term cause of mortality after transplant. The microbiome in healthy transplant recipients predicts subsequent development CLAD, but whether bacteria differ between CLAD and allografts unknown.MethodsWe performed a case control study using biorepository acellular bronchoalveolar lavage (BAL) fluid. Controls were specimens colle...
