Consciousness can be altered in many different ways. Drugs and medications can produce hallucinations (perception of things that are not there), change mood, or even wipe out consciousness (anesthetics). High fevers or prolonged starvation and many other forms of stress can have similar effects. Simpler methods also produce altered states of consciousness. This and the following exercises deal ...

There is no argument that understanding the geometry around optimal configuration is an important component for efficiency and injury prevention (Wisbey-Roth 2009), and some leading “Bike-Fit” proponents argue the neuromuscular perspective (Steve Hogg 2007). There are also endless references to optimal pedalling technique“spinning the pedals”, “elegant”, “wipe the mud of the shoe”, “like a duck...

It is shown that quantum coherence is conserved in a principal system in the case that the system is coupled to a fast dissipating environment [arXiv:0709.0562]. The phenomenon is called the quantum wipe effect. Here, this effect is reviewed and the analytical proof for a model system consisting of a one-qubit system coupled to a fast dissipating environment is extended to an environment at a t...

Growing attention on carcinogenicity and mutagenicity of antineoplastic drugs (ADs) from the International Agencies has led to present strict safe handling administration regulations. Accordingly, one most common ways assess occupational exposure these substances is identify quantify possible surface contamination inside hospital preparation units. Thus, it essential develop a fast high-through...

OBJECTIVE To evaluate the efficacy of a cleansing eyelid wipe in reducing the microbiota present on the ocular surface before cataract surgery. METHODS A single-center, prospective, single-blind phase IV study was conducted at the University Complutense of Madrid. Forty-five adult patients who were scheduled for ocular surgery after treatment with commercially available eyelid wipes were cons...

Activated carbon (AC) air cathodes were constructed using variable amounts of carbon (43–171 mg cm) and an inexpensive binder (10 wt% polytetrafluoroethylene, PTFE), and with or without a porous cloth wipe-based diffusion layer (DL) that was sealed with PDMS. The cathodes with the highest AC loading of 171 mg cm, and no diffusion layer, produced 1255 ¡ 75 mW m and did not appreciably vary in pe...

The COVID-19 pandemic triggered the widespread use and need for respirators face masks healthcare workers public. In this study, several generally available mask designs were fit tested, their materials evaluated filtration efficiency using 250 nm polystyrene latex particles. Efficiency testing was performed 2 0.5 h at low (2.6 L min–1) high (7.4 airflows, respectively, ~17.4 cm2 material area....

Background: Most cytotoxic drugs are unable to discriminate normal cells from cancer cells and they interfere with cell division and could lead to harmful effects such as carcinogenicity, genetic mutation, and teratogenicity. In order to assess dermal occupational exposure to cytotoxic drugs, surface sampling was used to determine the residual drugs on the working surfaces, as well as the effec...
