We have investigated the in vivo growth kinetics of a Salmonella typhimurium strain (P11D10) carrying a mutation in ssaJ, a Salmonella pathogenicity island 2 (SPI2) gene encoding a component of a type III secretion system required for systemic growth in mice. Similar numbers of mutant and wild-type cells were recovered from the spleens and livers of BALB/c mice up to 8 h after inoculation by th...

Purpose Shifting the region-of-interest within the input image to compensate for gaze shifts ("gaze compensation") may improve hand-eye coordination in visual prostheses that incorporate an external camera. The present study investigated the effects of eye movement on hand-eye coordination under simulated prosthetic vision (SPV), and measured the coordination benefits of gaze compensation. Me...

Weather regime forecasts are a prominent use case of sub-seasonal prediction in the midlatitudes. A systematic evaluation and understanding year-round forecast performance is still missing, however. Here we evaluate representation skill for seven Atlantic–European weather regimes reforecasts from European Centre Medium-Range Forecasts. Forecast calibration improves frequency biases most strongl...

• Optimal sizing of solar photo-voltaic/diesel generator/battery hybrid system for isolated islands India. Exclusive techno-economic investigation four different energy storage technologies the above system. Zinc bromine flow (ZBF) technology based offers highest return investment and renewable penetration with lowest simple payback period pollutant emissions. Sensitivity analysis ZBF integrate...

Abstract One of the key reasons contributing to a reduction in performance solar photovoltaic (SPV) system is presence partial shade on panels. It necessary use maximum power point tracking (MPPT) SPV systems get around non-linear behaviour This research analyses output caused by shading. In latter part paper, improved dynamic behaviour-based ant colony optimization MPPT approach under effect m...

Falls in seniors are a major public health problem. Falls lead to fear of falling, reduced mobility, and decreased quality of life. Vestibular dysfunction is one of the fall risk factors. The relationship between objective measures of vestibular responses and age has been studied. However, the effects of age on vestibular perception during caloric stimulation have not been studied. Twenty senio...

The term “polar vortex” remained largely a technical until early January 2014 when the United States (US) media used it to describe an historical cold air outbreak in eastern North America. Since then, has been more frequently by and public, often conflating circulation features temperatures near surface with only partially related at tropopause stratosphere. polar vortex its most common scient...

A solar photovoltaic distribution static compensator (SPV-DSTATCOM) under partial shading condition (PSC) is studied using a single-stage, 3-phase grid-connected mode. Under PSC, the performance of SPV-DSTATCOM and addressed issues such as active current sharing, reactive power control, harmonic elimination. Rejection DC offset with PSC an issue when conventional Proportional Resonant (PR) cont...
