  Scientific control - Wikipedia, the free encyclopedia
A scientific control augments integrity in experiments by isolating variables as dictated by the scientific method in order to make a conclusion about such variables.
The scientific control is used as a constant to show the effect a given environment has on certain variables.
A control sample where a negative result is expected, to help correlate a positive result with the variable being tested.

 A Short Course in Lab Vacuum, Part 2: Vacuum Control - BrandTech Scientific, Inc - Vacuum Pumps, Dispensers, Pipettes, ...
In this method, a controlled leak is introduced between the application and the vacuum pump.
VARIO™ Vacuum Control: This is a form of logic-based control for diaphragm pumps that requires the use of a electronic gauge and a variable speed motor.
The controller then compensates to slowly approach the boiling point, virtually eliminating overboiling, or “bumping.” Because the pressure over time is continually monitored, the vacuum level compensates for changes in application temperature and solvent composition.

 Resources: Trying to control the weather
When the study of the atmosphere became scientific, people began looking for scientific understanding that would help them exercise at least some control over the weather.
From the late 1940s into the 1960s, the term "weather control" was sometimes used.
The success of cloud seeding using silver iodide or other materials to increase the amount of precipitation from clouds led to the big interest in scientific weather control in the 1950s.

 Implementing Peer Review on the Net: Scientific Quality Control in Scholarly Electronic Journals.   (Site not responding. Last check: 2007-10-21)
To take advantage of this, paper publishing's traditional quality control mechanism, peer review, will have to be implemented on the Net, thereby recreating the hierarchies of journals that allow authors, readers, and promotion committees to calibrate their judgments rationally -- or as rationally as traditional peer review ever allowed them to do it.
So the COST of scholarly quality control certainly cannot be written off as part of the cost of paper publishing: Scholars have been subsidizing this with their free efforts all along.
It is also true that in all fields virtually everything that is written gets published somewhere; in the social sciences a manuscript may be submitted to a succession of lower and lower standard journals until it finds its niche; in physics authors may head more directly for something within their reach the first time round.

 Deferol - Premature Ejaculation Information & Climax Control Products
Deferol™ was scientifically formulated by pharmacists, pharmaceutical scientists, and sexual health researchers holding multiple patents relating to serotonin neurotransmission technologies.
There is definitive medical and scientific evidence referenced by The National Library Of Medicine (PubMed) [111 articles], that elevated levels of dopamine can have a profound negative impact on ejaculatory control in men and show that drugs which stimulate dopamine receptors can actually cause premature ejaculation.
In summary, the scientific rationale of the Climax Control Supplement Deferol™ was based on the synergistic scientific effects of its natural dietary ingredients which, in this Patent Pending combination, help to promote greater climax control and enable longer-lasting sexual intercourse.

Under-Monitor Displays are an important part of a router control system, allowing instant visual identification of the router source that is being fed to a monitor and providing indication of "tally" conditions.
When bringing an external router under the control of a Utah Scientific controller, it is necessary to provide a translation of the router commands between the internal (MX-Bus) control architecture and the remote control port provided by the external router.
In addition to translating the command protocol instructions, MX-Lator is capable of maintaining a memory image of the remote router, allowing the remote router to be fully integrated into the Utah Scientific control system, even in the absence of a full bi-directional control capability in the external router.

 Evidence on peer review—scientific quality control or smokescreen? - Education and Debate British Medical Journal ...
Peer review--the process by which experts advise editors on the value of scientific manuscripts submitted for publication--is traditionally surrounded by an almost religious mystique.
Peer review confers legitimacy not only on scientific journals and the papers they publish but on the people who publish them.
But if peer review is so central to the process by which scientific knowledge becomes canonised, it is ironic that science has little to say about whether it works.
