The weakening portion weakens the current-supply conductor upon indenting the contact pin, and the fixation portion causes the current-supply conductor to be fixed in the contact pin such that the end portion of the current-supply conductor can be readily torn off without the fixation of the current-supply conductor being substantially reduced.
During its fixation, the current-supply conductor is weakened at the location of the weakening portion to such an extent that, when a pulling force is exerted on the end portion of the current-supply conductor projecting from the contact pin, the current- supply conductor breaks off in a predetermined location.
The indentation 15 comprises a weakening portion 16 for weakening the current-supply conductor 5 during the manufacture of the electric lamp and comprises a fixation portion 18 for fixing the current-supply conductor 5 in the contact pin 4.

 Monotonicity of entailment - Wikipedia, the free encyclopedia
In sequent calculi this property can be captured by an inference rule called weakening, or sometimes thinning, and in such systems one may say that entailment if monotone just in case the rule is admissible.
In most logics, weakening is either an inference rule or a metatheorem if the logic doesn't have an explicit rule.
Bunched implications where weakening is restricted to additive composition.

 Climate Change 2001: The Scientific Basis   (Site not responding. Last check: 2007-11-05)
In the SAR, it was noted that the thermohaline circulation (THC) weakens as CO increases in the atmosphere in most coupled climate model integrations.
The weakening of the THC in the Atlantic Ocean results in a reduction of the poleward heat transport that in turn leads to a minimum in the surface warming in the northern North Atlantic Ocean and/or in the circumpolar Ocean (see Section 9.3.2).
A recent study (Stouffer and Manabe, 1999) found that the amount of weakening of the THC by the time of CO doubling is a function of the rate of CO increase and not the absolute increase in the radiative forcing.

 Earth's magnetic field weakening - Science - MSNBC.com
Instead, the weakening, measured since 1845, could represent little more than an "excursion," or lull, in the naturally variable strength of the Earth's magnetic field, said John Tarduno of the University of Rochester.
Over the southern Atlantic Ocean, a continued weakening in the strength of the magnetic field has diminished the shielding effect it has locally in protecting the Earth from the natural radiation that bombards our planet from space, scientists said.
The weakening, if coupled with a subsequently large influx of radiation in the form of protons streaming from the sun, can also affect the chemistry of the atmosphere, said Charles Jackman of NASA's Goddard Space Flight Center.

 FRICTIONAL WEAKENING AND SLIP COMPLEXITY IN EARTHQUAKE FAULTS -- Web of Science version 4.1 (ISI1)   (Site not responding. Last check: 2007-11-05)
In addition, a possible physical origin of frictional weakening is examined, through a very simplified mathematical representation of a physical process proposed by Sibson (1973), whereby frictional heating causes an increase in pore fluid temperature and pressure, thereby reducing the effective normal stress and friction.
The two different types of frictional weakening are derived from two opposing limits, with slip weakening occurring when the dissipation of heating is slow compared to the rupture timescale, as Lachenbruch (1980) has shown, while velocity weakening is shown to occur when the dissipation is fast compared to the rupture timescale.
Since both end-member cases of frictional weakening are seen to produce slip complexity, slip complexity is argued to be a generic feature of frictional weakening and elastodynamics on a fault.

 President Boxer: Public Weakening
They just want to weaken her so they can score points against this administration and the majority party in general.
Their motivation was simply to "get" the guy they didn't like and to trample him (perhaps one could phrase it as "weakening") for the sole purpose of scoring points for their side (one might phrase it as "partisan gain").
If this weakens the nominee, it is only because they aren't used to someone on this side of the fence standing up and being strong.

 Greenhouse Effect Weakening?   (Site not responding. Last check: 2007-11-05)
A new study appearing in the January 10 issue of Geophysical Research Letters has found that the greenhouse effect may be weakening due to changes in cloud cover that do not correspond with climate model predictions.
The study, conducted by Robert Cess, with the State University of New York at Stony Brook, and his late colleague Petra Udelhofen, looked at the role of clouds on climate in the tropics and subtropics by comparing the results of a climate model to observations.
With the exception of a few years after the eruption of Mt. Pinatubo, the increase in OLR has been fairly steady.

 SCEC Research: 1998 Research
The laboratory evidence bearing on models of weakening in the dynamic regime has been almost non-existent, and we have been obliged to use plausible models obtained from low strain-rate, i.e.
Rice and Lapusta have shown that crack growth in a weakening regime characterized by the rate-state rule, develops a series of slip pulses that develop as a sequence of instabilities.
Knopoff and Landoni have shown analytically that the ad hoc assumption of either a linear slip weakening law or a linear velocity weakening law in the vicinity of a crack edge is non-physical.

 Introduction   (Site not responding. Last check: 2007-11-05)
The differences in the rate of weakening between Model A and Model B are evident in the rate of decay of their respective slip-velocity histories.
Consequently, with the possible exception of Ide and Takeo’s (1997) 1 m slip weakening distance (slow rate of weakening) for the shallow Nojima Fault, none of the presently available determinations of slip weakening distance or strength excess based on waveform inversion is unique.
The fundamental ambiguity is that strength excess and slip weakening distance have competing effects on rupture velocity, which largely controls the waveforms.

 Selective Memoization and Goal-weakening
The goal weakening technique can also be used to eliminate typical instances of the problems concerning the occur check (discussed in the previous subsection).
For the experiments discussed in the final section all goal weakening operators were chosen by hand, based on small experiments and inspection of the goal table and item table.
For the current version of the grammar of OVIS, it turned out that weakening the goal category in such a way that all information below a depth of 6 is replaced by fresh variables eliminated the problem caused by the absence of the occur check; moreover this goal weakening operator reduced parsing times substantially.

 NASA - Top Story - SATELLITES RECORD WEAKENING NORTH ATLANTIC CURRENT - April 15, 2004
The current, known as the sub polar gyre, has weakened in the past in connection with certain phases of a large-scale atmospheric pressure system known as the North Atlantic Oscillation (NAO).
The cycle is sensitive to the paths of winter storms and to the buoyant fresh water from glacial melting and precipitation, all of which are experiencing great change.
While previous studies have proposed winds resulting from the NAO have influenced the subpolar gyre's currents, this study found heat exchanges from the ocean to the atmosphere may be playing a bigger role in the weakening current.

 Chemicals and Effects Upon Health
Petroleum based chemicals are believed to cause these problems by a variety of routes including - impairing proper DNA (Gene) expression, weakening DNA Repair, accelerating gene loss, degeneration of the body's detoxification defenses (liver and kidneys) as well as gradual weakening of the brain's primary defense - (the Blood Brain Barrier).
Identifying a specific chemical as the "original cause" of these health disorders is difficult and often overlooked as it typically requires years of exposure for the body's inherent defenses to weaken sufficiently to result in observable health problems.
Observed effects include weakening of the immune system (thereby resulting in increased colds, flu and infections), birth defects, genetic damage, accelerated aging of certain body organs, increased neurological damage to the elderly and serious harm to wildlife.

Movie star Leonardo DiCaprio was received warmly by students when he, along with Carol Browner, former head of the Environmental Protection Agency during the Clinton administration, made an appearance at the Phyllis P. Marshall Center on Wednesday to delivered a damning indictment against the Bush administration's environmental record.
The Natural Resources Defense Council lists more than 400 instances in which the Bush administration in part weakened environmental standards ranging from water pollution, which led to recent warnings about mercury in Florida's lakes and rivers, to so-called point sources, industrial polluters emitting pollution at one spatially restricted source.
In what Kennedy labels a "stealth attack," Bush has gradually replaced virtually all individuals holding positions in the agency with lobbyists that favor the very sectors they are supposed to oversee.

 CATHOLIC ENCYCLOPEDIA: The Reformation
The reform councils of the fifteenth century, instead of improving the situation, weakened still more the highest ecclesiastical authority by reason of their anti-papal tendencies and measures.
In princes and governments there had meanwhile developed a national consciousness, purely temporal and to a great extent hostile to the Church; the evil powers interfered more frequently in ecclesiastical matters, and the direct influence exercised by laymen on the domestic administration of the Church rapidly increased.
King Christian II of Denmark (1513-23) welcomed the Reformation as a means of weakening the nobility and especially the clergy (who possessed extensive property) and thereby extending the power of the throne.
