A chemical active medium on the base of Belousov-Zhabotinsky (BZ) medium was used to design a “chemical diode”. This system, similar to a semiconductor diode, shows unidirectional propagation of chemical pulses and may be possible to be used to construct a massively parallel computational medium. The system of two mesoporous glass plates with ferroin loaded at the surface was covered by BZ solu...

Some authors in fact refer to episodes as chemical arachnoiditis. Jolles et al. at the National Institute for Medical Research, London, ( [1] ) discussed Drug-induced aseptic meningitis (DIAM), which they denoted as "uncommon." The authors remarked that most of the literature comprises anecdotal case reports. The major types of causative drugs are nonsteroidal anti-inflammatory drugs ...

This SafetyNet suggests chemical substitutes for commonly used chemicals to promote a safer work environment. Consider using the safer substitute if it works in your process: Sample of Chemical Substitute List. View full list here [1].

An attempt to condense the important knowledge in a broad field into a small volume is fraught with danger. It is particularly hazardous when the field at issue is one which straddles two established disciplines such as biochemistry and microbiology. A. H. Rose is aware of the problems inherent in his task, and it is probably due in no small part to this awareness that he brings it off so well....

We show how to include a chemical potential µ in perfect lattice actions. It turns out that the standard procedure of multiplying the quark fields Ψ, ¯ Ψ at Euclidean time t by exp(±µt), respectively, is perfect. As an example, the case of free fermions with chemical potential is worked out explicitly. Even after truncation, cutoff effects in the pressure and the baryon density are small. Using...

Chemical Cocktails Are Mixed Pesticides More Potent? Increasing evidence suggests that environmental chemicals that interact with the endocrine system harm the health of humans and animals. More recent studies suggest further that these chemicals act synergistically, meaning that their combined effect is greater than the sum of their individual effects. While few scientists doubt that endocrine...

Vertebrate nervous systems are composed of two principal cell types: glia and neurons. Glial cells are the most abundant and are involved primarily in maintaining ion homeostasis in the brain. Information processing is performed by neuronal cells that form intricate networks of processes capable of conducting and transferring electrical information at high speed and high efficiency. Neurons are...

A 32 year old man working in a jewellery shop unknowingly used nitric acid which is used for cleaning of jewels, in the toilet for cleaning. After inhalation of acid fumes he developed cough, breathlessness, chest tightness and got admitted in our hospital. On examination patient was conscious, oriented, not cyanosed, tachypneic, but with normal SpO2 and stable vital parameters. He had bilatera...
