In November 1950, a relatively modern factory, called Alpha, was established in Javadiyeh district of Tehran. It was the first factory of milk pasteurization in Iran, which started by pasteurizing five tons of milk per day and manufacturing dairy products. The factory was under official health supervision of Pasteur Institute of Iran and had a significant contribution to the improvement of the ...

With the rapid development of nanotechnology, metallic (metal or metal oxide) nanoparticles (NPs) are widely used in many fields such as cosmetics, the food and building industries, and bio-medical instruments. Widespread applications of metallic NP-based products increase the health risk associated with human exposures. Studies revealed that the brain, a critical organ that consumes substantia...

The development of modern science requires the equipment grid to provide a scientific collaboration research platform, which can realize remote collaboration and sharing with the key instruments and equipment in wide areas. The reliability and high efficiency of a grid service chain model are key points in creation of a grid equipment system. The π-calculus as powerful process algebra has a spe...

Trephination and craniotomy performed by abrasion, scraping, crosscut sawing, and drilling are the oldest known surgical techniques used by primitive peoples. As a result of archaeological findings, the human skull is the most frequently studied part of the excavated body, leading to the creation of a new aspect of anthropology known as "cultural osteology." Found in ancient tombs, the human re...

Abstract Recently, there has been increased concern about emerging pollutants (EPs). Many EPs can be found in consumer products and are regarded as primary indoor contaminants. This review paper focuses on the overview of some chemical pollutants, their negative health effects, appropriate sampling methods, drawbacks associated with them, analytical techniques used. Some challenges identified d...

chromatography (UHPLC) has taken a firm foothold in the analytical laboratory. However, it is rare that 100% of instrumentation within a company is all from the same vendor and of the same model. Differences between equipment can lead to unexpected changes in the chromatogram when a method is transferred from one system to another. In this issue of Separation Science we examine these issues and...

ophthalmic equipment, including surgical instruments and diagnostic devices, can be compared to the maintenance of a motor vehicle, something many of us understand well. If you had a car, would you drive it until the fuel runs out or until a tyre punctures, and then abandon it to buy a new car? Of course not. However, many eye care units purchase (or receive as a donation) expensive and delicat...
