<h3>Purpose</h3> As part of the Avahan India AIDS Initiative, a behaviour change communication programme sought to increase consistent condom use (CCU) among male clients female sex workers (FSWs) in four Indian states through outdoor static promotional materials, interpersonal and mid-media activities. This paper presents key findings related coverage levels, trends over time self-reported use, correlations between levels exposure activities use. <h3>Methods</h3> Five stratified two-stage...

Injection locking characteristics of oscillators are studied both qualitatively and analytically the closed-form expressions frequency-pulling spectrum unlocked driven oscillator is estimated with negligible amplitude perturbation. Modifications in spectrum, lock range, pulling shown under significant Also an approximate expression perturbation presented. Numerical simulations experimental results describing oscillator's process given.

An optoelectronic oscillator (OEO) under the influence of a weak interference has been investigated. The system equation OEO derived. A novel technique for calculating lock range using harmonic balance method in presence demonstrated. Theoretical analysis coupled with experimental results presented.

This paper audits the output carrier-to-noise ratio of a single-loop OEO when incoming signal is contaminated with additive white Gaussian noise. Investigations have been carried out for possibility increasing ratio. A detailed analysis hysteresis or `jump phenomenon' has reported by utilizing Lyapunov stability criterion. The total distortion power derived assuming Carson's rule bandwidth to hold, at input port OEO. It observed that injection synchronized acts as an amplifier FM

Accurate etiological diagnosis is the key to prevention of ocular morbidity in endophthalmitis cases. A 66 year old male was suffering from chronic post-cataract surgery. Polymerase chain reaction examination on anterior chamber fluid positive for Propionibacterium acnes but negative panfungal genome. He advised vitrectomy with intravitreal injections. vitreous aspirate P.acnes as well The sample also grew yeast culture which identified Candida pseudotropicalis. Patient treated an alternate...

ANDLER and NOVITSKI (1957) proposed the term “meiotic drive” (or segregation distortion) to describe a condition which leads unequal of two alleles present in heterozygote consequence certain aberrant mechanisms during meiosis. SANDLER, HIRAXZUMI SANDLER (1959) HIRAIZUMI (1959, 1960) have made detailed analysis this distortion phenomenon Drosophila melunogaster they shown that it may be attributable one or more mutant gene (SD factor) located centromeric heterochromatin second chromosome....

This study introduces the concept of dynamic controlled bandpass filter (BPF) to achieve improved synchronisation capability a single‐loop optoelectronic oscillator (OEO) under effect externally applied angle modulated signal. The governing equation for ability an OEO using control BPF has been derived. Theoretical and comparison locking enhancement this over conventional static are provided which is properly validated by simulation. Finally, frequency modulation amplitude conversion...

We investigate the dynamics of a modified optoelectronic oscillator (OEO) through theoretical and numerical analysis. The OEO under study is different from conventional in sense that it contains van der Pol (VDPO) its feedback loop, place RF band pass filter. Two coexisting limit cycle oscillations are identified, known as birhythmicity. Subsequently, simple self-feedback scheme introduced to control birhythmic behavior oscillator. To best our knowledge, birhythmicity an intrinsic...

Two-photon absorption cross sections of two dye molecules, doped in thin films polymethylmethacrylate, are measured by comparing fluorescence intensities induced single- and two-photon excitations. Ratio the is related to ratio pumped intensities. Using this sensitive background-free detection technique, dispersion nonlinearity over a wavelength range 700–800 nm.

In future generation pico-cellular mobile communications FM-sideband injection of two laser sources are used to generate mm-wave signals. This paper considers some over- looked issues with particular emphasis on the loss coherence between lasers due cycle slipping phenomenon and suggests a new tracking system, that considerably improves performance. DOI: 10.2529/PIERS061004061503 Increasing demand for broadband communication limited atmospheric propagation at mm-waves has resulted in need...

Nothing has yet been reported on the existence of Barkhausen criterion and synchronization phenomenon in a LIMO. The present paper, aside considering influence forcing signal, discusses effect amplitude modulated synchronizing signal LIMO corresponding AM-PM conversion for injection synchronized is studied detail. In contradistinction to previous works [1–9], three interesting results are this viz., (1) Modified criterion, resulting dependence free running frequency oscillation loop-delay,...
