Buildings laboratories

In the early days of the chemical industry, manufacturers were reluctant to set up laboratories, but towards the end of the nineteenth century firms started to build laboratories both for analysis and research.280281 Analysis also played a role in the development of the laboratory in the early pharmaceutical industry.282 The history and development of the analytical and quality control laboratories at the Merck company in Darmstadt has been examined.283 The changing role of the chemist in the British alkali industry has also been investigated.284,285... 

The WWC program consists of experiment groups that each initially included a scenario and a set of three experiments—a skill-building laboratory, a foundation laboratory, and an application laboratory. The scenario presents a situation or problem that nonchemistry professionals, such as an ecologist or a nurse, may encounter in their field. Examples of four experiment groups are provided later in this chapter. 

In the application laboratory, students determine the quantity of carbon dioxide produced from the decay of leaves over a given period of time and report their results as milligrams of C02 per gram of leaf per day. They set up compost jars and a control jar a week in advance to give the leaves a chance to decay. The students back titrate to determine the number of moles of sodium hydroxide left unreacted, which enables them to ultimately determine the quantity of carbon dioxide produced from the decay of the leaves. The previously done skill -building laboratory has given them experience with back titrations when they analyzed the number of moles of hydrochloric acid neutralized by different commercial antacids. 

That same year, a U.S. federal grand jury issued an indictment against the Panamanian leader Manuel Noriega. Noriega, it was charged, had cooperated with drug traffickers, allowing them to use his country to launder money as well as to build laboratories to process cocaine in Panama. On December 20,...

The community of microfluidics aims at building laboratories-on-a-chip. These tiny fluid microprocessors perform complex analysis and synthesis tasks relevant to chemistry or biology. The ability to reliably dispense and control small fluid volumes in the form of drops or bubbles in the charuiels of a microfluidic chip is important for microfluidic applications, because bubbles can enhance mixing and droplets can encapsulate... 

As in the situation with fires or spills, it is best to turn off equipment before leaving a lab if it is possible to do so safely. If electrical power is lost in a building, laboratory fume hoods will not work. Any materials in the hoods should be capped, if it is possible to do so safely before leaving. 

Main and multiunit substations should not be part of administration buildings, shops, control buildings, laboratories, or any other nonrelated structure. In locations where it is deemed absolutely necessary to combine a main or multiunit substation with another structure, the substation should be separated by a 3-hour rated firewall with no direct access or any other penetration through the wall. 

In the American plants women are employed in process buildings where there is a radiation hazard (e.g. on monitoring work in the pile building). This is considered inadvisable as an initial step and it is not proposed that women should be employed in process or other buildings where there are minor risks of exposure to mild radiation in the ordinary course of routine duties. This excludes them from Process buildings, laboratories, laundries etc in the Pile and Separation Groups. 

Ridge building laboratory experiments (Tuhkuri and Lensu, 1997) show periodic oscillations of the ice sheet with a well-pronounced peak of 9 Hz. The same mechanisms may be responsible for the oscillations observed in the field.
