The effectiveness of the tin foil hat as electromagnetic shielding for stopping radio waves is greatly reduced by it not being a complete enclosure.

Electronics can be shielded by wrapping them completely in conductive material such as aluminum foil ; however, the effectiveness of the shielding may be less than perfect.

The welder will judge the effectiveness of the shielding and increase the nozzle size to increase the area protected by the external gas shield as needed.

The effectiveness of this type of shielding depends on the material's permeability, which generally drops off at both very low magnetic field strengths and at high field strengths where the material becomes saturated.

This coefficient describes the effectiveness of this material in shielding the external magnetic field from the cavity that it surrounds.

The main purpose of the flight phase was examining the effectiveness of the radiation shielding which was one of the main concerns for the engineers.

The solar-electromagnetic- and corpuscular-radiation pressure and the associated Poynting-Robertson effect increase in effectiveness as the particle size decreases and modify the distribution and limit sizes to larger than a few microns.

As the sorbent saturates, the effectiveness of a sorption pump decreases, but can be recharged by heating the zeolite material ( preferably under conditions of low pressure ) to outgas it.

UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids.

Percutaneous radiofrequency thermorhizotomy may also be effective as may gamma knife radiosurgery however the effectiveness decreases with time.

In other words, increased surface area ( in contact with the fluid in the lumen ) decreases the average distance traveled by nutrient molecules, so effectiveness of diffusion increases.

The pitch's effectiveness also decreases substantially if it cannot be thrown accurately for strikes.

This rapidly expanding ring, when hitting the aircraft, can be more effective than an equivalent fragmentation warhead: the ring's effectiveness decreases as 1 / R, rather than 1 / R ^ 2 for fragments.

Upon touchdown the flaps immediately return to the 25 ° position which decreases the lift created by the wing thereby increasing braking effectiveness.

Some servers enable temporary-lasting power-ups that grant multiplied damage ( Berserker ), invisibility ( Predator ), a flamethrower along with temporary invincibility ( FlameGod ), or Cluster Grenades ( which temporarily replace regular grenades with three of more powerful, modified versions ) or even a Bulletproof Vest ( effectiveness of the vest depends on the distance from the firer of the bullet, and the vest slowly decreases as it soaks up damage, disappearing after absorbing a certain amount of damage, though there is no time limit ).

As such, as the size of an organizational unit increases, the effectiveness of internal knowledge flows dramatically diminishes and the degree of intra-organizational knowledge sharing decreases.

As the speed decreases, the rudder will lose effectiveness and the pilot will need to control the direction of the airplane using nose wheel steering, a system which typically is not connected to the flight control computer.

A 2000 systematic review of water fluoridation's effectiveness found that fluoridation was associated with a decreased proportion of children with cavities ( the median of mean decreases was 14. 6 %, the range − 5 % to 64 %), and with a decrease in decayed, missing, and filled primary teeth ( the median of mean decreases was 2. 25 teeth, the range 0. 5 to 4. 4 teeth ).

Unlike stones that can become rounded, which decreases their effectiveness, diamond plates remain flat.

Clearly, if a social norms campaign does not reach very much of its intended audience, then its potential effectiveness decreases.

In cooperating toward that objective, OAS might move with the speed and effectiveness demonstrated by the United States.

All comments concerning effectiveness and use of drugs have been carefully reviewed by a veterinary medical officer with Aj.

Whether this abnormal TSH differs chemically from pituitary TSH, or is, alternatively, normal TSH with its period of effectiveness modified by some other blood constituent, cannot be decided without chemical study of the activity in the blood of these patients and a comparison of the substance responsible for the blood activity with pituitary Aj.

However, the monetary authorities will continue to be required to pay attention to the consequences of their actions with respect to our international balance of payments position and the outflow of gold, as well as with regard to avoiding the creation of excessive liquidity in the economy, which would delay the effectiveness of monetary policy measures in the next expansion phase of the business cycle.

Bloch was not concerned with the effectiveness of the royal touch — he acted instead like an anthropologist in asking why people believed it and how it shaped relations between king and commoner.

Although this policy met with initial success, it gradually undermined the relative effectiveness of imperial bureaucracy by placing family connections over merit.

A systematic 2003 review of controlled clinical trials related to the Alexander Technique found two reputable studies suggesting the Alexander Technique is effective in reducing the disability of patients suffering from Parkinson ’ s disease and improving pain behaviour and disability in patients with back pain, and concluded that the evidence supporting the effectiveness of the Alexander Technique is encouraging but not convincing.

The development of new antipsychotics with fewer of these adverse effects and with greater relative effectiveness as compared to existing antipsychotics ( efficacy ), is an ongoing field of research.

Some doubts have been raised about the long-term effectiveness of antipsychotics for schizophrenia, in part because two large international World Health Organization studies found individuals diagnosed with schizophrenia tend to have better long-term outcomes in developing countries ( where there is lower availability and use of antipsychotics and mental health problems are treated with more informal, community-led methods only ) than in developed countries.

That this day coincides with Christian Sabbath is not a bar to the state's secular goals ; it neither reduces its effectiveness for secular purposes nor prevents adherents of other religions from observing their own holy days.

Due to their effectiveness, tolerability, and rapid onset of anxiolytic action, benzodiazepines are frequently used for the treatment of anxiety associated with panic disorder.

Tolerance to anti-anxiety effects develops more slowly with little evidence of continued effectiveness beyond four to six months of continued use.

Marketing applications generally come with predictive analytics to improve segmentation and targeting, and features for measuring the effectiveness of online, offline, and search marketing campaigns.

Mars has become the new central hub of human civilization, and interplanetary crime syndicates exert influence over the government and the Inter-Solar System Police ( ISSP ), limiting their effectiveness in dealing with crime.

While a professor of psychology at the University of Chicago ( 1945 – 57 ), Rogers helped to establish a counseling center connected with the university and there conducted studies to determine the effectiveness of his methods.

The relative effectiveness of IRS ( with DDT or alternative insecticides ) versus other malaria control techniques ( e. g. bednets or prompt access to anti-malarial drugs ) varies greatly and is highly dependent on local conditions.

, no patients had been treated with DCA in a clinical trial, and so its actual effectiveness is unknown.
