" It is highly probable that the correct information about the sulphonamide did not reach the newspapers because, since the original sulphonamide antibacterial, Prontosil, had been a discovery by the German laboratory Bayer, and as Britain was at war with Germany at the time, it was thought better to raise British morale by associating Churchill's cure with the British discovery, penicillin.

The laboratory at St Mary's Hospital where Fleming discovered penicillin is home to the Fleming Museum, a popular London attraction.

Biomedical research on these parasites is challenging because it is often difficult, if not impossible, to maintain live parasite cultures in the laboratory and to genetically manipulate these organisms.

* There is evidence that exposure may cause demyelinating disease in laboratory animals.

Thus, natural beryllium bombarded either by alphas or gammas from a suitable radioisotope is a key component of most radioisotope-powered nuclear reaction neutron sources for the laboratory production of free neutrons.

Of these features, dark matter is currently subjected to the most active laboratory investigations.

In simpler term, Biotechnology is the research and development in the laboratory that involves bioinformatics for exploration, extraction, exploitation and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned ( reproduced by Biosynthesis, for example ), fore-casted, formulated, developed, manufactured and marketed for the purpose of sustainable operations ( for the return from bottomless initial investment on R & D ) and gaining durable patents rights ( for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects on safety concerns by using the products ), for more about the biotechnology industry, see.

The CDC thus only recommends vaccination for: 1 ) All laboratory and field personnel who are working with Y. pestis organisms resistant to antimicrobials, 2 ) People engaged in aerosol experiments with Y. pestis and 3 ) People engaged in field operations in areas with enzootic plague where preventing exposure is not possible ( such as some disaster areas ).

A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.

The hose barb is connected to a gas nozzle on the laboratory bench with rubber tubing.

A fire is soon started in the laboratory, killing Lobo.

The chemistry laboratory stereotypically uses various forms of laboratory glassware, but glassware is not central to chemistry, and a great deal of experimental ( as well as applied / industrial chemistry ) is done without it.

The potency of different venoms varies ; lethal venoms are often characterised by the median lethal dose ( LD < sub > 50 </ sub >) which will kill 50 % of victims, typically laboratory mice, expressed in milligrams of venom per kilogram of body weight.

The young typically reach sexual maturity in about three days, and gastrotrichs can live up to ten days under laboratory conditions.

Although occasionally used as a synonym for biofilm, the term primarily applies to the simple, clonal, unstructured mats of organisms that typically only form on laboratory growth media.

In some markets, the different available flour varieties are labeled according to the ash mass (" mineral content ") that remains after a sample is incinerated in a laboratory oven ( typically at 550 ° C or 900 ° C, see international standards ISO 2171 and ICC 104 / 1 ).

Fractional distillation in a laboratory makes use of common laboratory glassware and apparatuses, typically including a Bunsen burner, a round-bottomed flask and a condenser, as well as the single-purpose fractionating column.

Requirements differ for different trials, but typically volunteers will have the following tests in a medical laboratory:

Rats and mice typically sport around 30 whiskers on each side of the face, with whisker lengths up to around 50 mm in ( laboratory ) rats and 30 mm in ( laboratory ) mice.

The photo-chemical process is also referred to as color timing and is typically performed at a photographic laboratory.

Each collaboration chooses the roles and responsibilities of the spokesperson for internal purposes, but typically spokespersons also have defined roles for liaising with the host laboratory and / or funding agencies.

Such research typically includes direct interpretation of the monitoring and eruption data, and it leads to formulation of conceptual models that can be tested by theoretical or laboratory simulations of volcanic systems.

More typically for laboratory operations, the Prilezhaev reaction is employed.

In experiments, In situ typically refers to those experiments done in a field setting as opposed to a laboratory setting.

The term " blood bank " typically refers to a division of a hospital laboratory where the storage of blood product occurs and where proper testing is performed to reduce the risk of transfusion related events.

Definitive diagnosis of arbovirus infections is typically made in a laboratory by employing some combination of blood tests, particularly immunologic, serologic and / or virologic techniques such as ELISA, complement fixation, polymerase chain reaction, Neutralization test and Hemoagglutination Inhibition test.

The applications of immunostaining are numerous, but are most typically used in clinical diagnostics and laboratory research.

There are two general sets of questions that experimental economists typically ask when examining such games: ( 1 ) Can laboratory subjects coordinate, or learn to coordinate, on one of multiple equilibria, and if so are there general principles that can help predict which equilibrium is likely to be chosen?

This typically is initiated when a sample is received in the laboratory, at which point the sample will be registered in the LIMS.

Comprehensive physical exams of this type are also known as executive physicals, and typically include laboratory tests, chest x-rays, pulmonary function testing, audiograms, full body CAT scanning, EKGs, heart stress tests, vascular age tests, urinalysis, and mammograms or prostate exams depending on gender.

When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently crimped or soldered to a wire, or is bent to form the inner tubular contact of a ~ 4 mm female banana jack, enabling quick non-permanent connection between a circuit under test and laboratory equipment or to another electrical circuit.
