Sexual health communication between sex worker mothers and their children in India.

In India, relatively little is known about sex worker mothers' beliefs regarding sexual health communication with their children. Using qualitative data collected in Kolkata, India, this study used the Parent Expansion of the Theory of Planned Behaviour to examine sex worker mothers' beliefs about sexual health communication and factors shaping these beliefs. Sex worker mothers' beliefs about sexual health communication were shaped by societal norms and collectivising processes often driven by Durbar Mahila Samanwaya Committee (DMSC), a sex workers' collective in Kolkata, India.

Using accelerometer as a diagnostic tool to detect drug-induced parkinsonism (DIP) secondary to first-generation anti-psychotic medications.

Objective: The objective of this study is to examine the effectiveness of an accelerometer-based compact system in detecting and quantifying drug-induced parkinsonism (DIP) in patients with schizophrenia.

Method: A pilot study controlled clinical trial comprising 6 people with schizophrenia and 11 control subjects was conducted at Alfred Health, Melbourne. Participants had their movements assessed using Barnes Akathisia Rating Scale (BARS), Simpson Angus Scale (SAS) and Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS III) followed by an assessment of gait using three triaxial accelerometers.

Stochastic resonance with a mesoscopic reaction-diffusion system.

In a mesoscopic reaction-diffusion system with an Oregonator reaction model, we show that intrinsic noise can drive a resonant stable pattern in the presence of the initial subthreshold perturbations. Both spatially periodic and aperiodic stochastic resonances are demonstrated by employing the Gillespies stochastic simulation algorithm. The mechanisms for these phenomena are discussed.

Healing of broken multiwalled carbon nanotubes using very low energy electrons in SEM: a route toward complete recovery.

We report the healing of electrically broken multiwalled carbon nanotubes (MWNTs) using very low energy electrons (3-10 keV) in scanning electron microscopy (SEM). Current-induced breakdown caused by Joule heating has been achieved by applying suitably high voltages. The broken tubes were examined and exposed to electrons of 3-10 keV in situ in SEM with careful maneuvering of the electron beam at the broken site, which results in the mechanical joining of the tube.
