(v. t.) A baser metal mixed with a finer.
(v. t.) Admixture of anything which lessens the value or detracts from; as, no happiness is without alloy.
(v. t.) To reduce the purity of by mixing with a less valuable substance; as, to alloy gold with silver or copper, or silver with copper.
(v. t.) To mix, as metals, so as to form a compound.
(v. t.) To abate, impair, or debase by mixture; to allay; as, to alloy pleasure with misfortunes.
(v. t.) To form a metallic compound.

(8) The investment containing 2.0 wt% NbC showed nearly the same casting accuracy for Ni-Cr alloys for metal-ceramic restoration as the commercial phosphate-bonded investment.
(9) It was determined that the Ag-rich phase of Ag-Pd-Cu-Au alloy was preferentially attacked to form Ag2S corrosion product.
(10) The current literature, for the most part, cites the use of noble alloys as controls for trials of alternative materials.
(11) Titanium-nickel alloy composed of 50% by weight of each metal has unique thermal shape-memory properties, with a transition temperature of 20 degrees C. Each stent consists of one wire with a diameter of 0.9 mm.
(12) Irrespective of the coated dental alloy, the coatings have pores, through which the electrolyte is in contact with the substrate material.
(13) Forty BIAS femoral stems had heads made of Co-base F 75 alloy and 18 Gustilo-Kyle femoral stems had Ti6A14V alloy heads.
(14) The occurrence of marginal spaces between the resin facing and gold alloy framework in 176 crowns and bridge retainers was studied.
(15) Base metal alloys, principally made of nickel, chromium, and beryllium have gained widespread usage, especially in the United States, due to their lower cost and higher mechanical properties.
(16) The amounts of polyethylene and methylmethacrylate debris and the histological reactions in the tissues corresponded closely with those reported in earlier studies of total hip prostheses made of stainless steel or cobalt-chromium alloy.
(17) The bond strength of the specimens brazed with the non-precious alloy was largely unaffected.
(18) The traditional alloys used as metal bases for fixed partial dentures are accompanied by various problems such as corrosion, allergy, toxicity, casting, and preparation for both patient and prosthodontist and in magnetic resonance imaging for diagnosis.
(19) The results revealed that experimental alloys inherited high early and final strength values without any significant change in their microstructure.
(20) The surface of dental alloys, on which such a composite plating was made, was analyzed by ESCA.
(v. t.) To make worse; to diminish in quantity, value, excellence, or strength; to deteriorate; as, to impair health, character, the mind, value.
(v. t.) To grow worse; to deteriorate.
(a.) Not fit or appropriate.
(n.) Diminution; injury.
(1) Clinical signs of disease developed as early as 15 days after transition to the experimental diets and included impaired vision, decreased response to external stimuli, and abnormal gait.
(2) The various evocational changes appear to form sets of interconnected systems and this complex network seems to embody some plasticity since it has been possible to suppress experimentally some of the most universal evocational events or alter their temporal order without impairing evocation itself.
(3) The CHI patients were impaired overall on the FTE but not the CTE.
(4) We studied the effects of the localisation and size of ischemic brain infarcts and the influence of potential covariates (gender, age, time since infarction, physical handicap, cognitive impairment, aphasia, cortical atrophy and ventricular size) on 'post-stroke depression'.
(5) Changes in renal renin levels after the administration of glycerol were not significant, although lower renal renin values were consistently found in rabbits with more severe impairment of renal function.
(6) These findings suggest that aerosolization of ATP into the cystic fibrosis-affected bronchial tree might be hazardous in terms of enhancement of parenchymal damage, which would result from neutrophil elastase release, and in terms of impaired respiratory lung function.
(7) There was no correlation between disturbed gastric clearance, impaired gall bladder contraction, and prolonged colonic transit time in the patients with cardiovascular autonomic neuropathy nor was there a correlation between any disturbed motor function and age or duration of diabetes.
(8) No biologic investigation of the hemostatic impairment could be performed under the emergency conditions of this field study.
(9) Two hours after the administration, the combinations of ethanol plus diazepam and ethanol plus meclophenoxate impaired significantly the number of necessary repetitions.
(10) The effect of dietary fibre digestion in the human gut on its ability to alter bowel habit and impair mineral absorption has been investigated using the technique of metablic balance.
(11) The Test of Motor Impairment (TOMI) was used to select 12 children with a Developmental Coordination Disorder (DCD) and 12 age-matched controls.
(12) Patients with MID, but not those with DAT, exhibited correlations between enlargement of the third and lateral ventricles and severity of cognitive impairment.
(13) ACTH 4-10 appeared to slightly impair selective attention as indicated by AEP responses.
