Factorial experiment on cycles to failure of worsted yarn

Normal oral food ingestion processes such as mastication would not have been possible without the teeth. The human teeth are subjected to many cyclic loadings per day. This, in turn, exerts forces on the teeth just like an engineering material undergoing the same cyclic loading. Over a period, there will be the creation of microcracks on the teeth that might not be visible ab initio. The constant formation of these microcracks weakens the teeth structure and foundation that result in its fracture. Therefore, the need to predict the fatigue life for human teeth is essential. In this paper, a continuum damage mechanics (CDM) based model is employed to evaluate the fatigue life of the human teeth. The material characteristic of the teeth is captured within the framework of the elastoplastic model. By applying the damage evolution equivalence, a mathematical formula is developed that describes the fatigue life in terms of the stress amplitude. Existing experimental data served as a guide as to the completeness of the proposed model. Results as a function of age and tubule orientation are presented. The outcomes produced by the current study have substantial agreement with the experimental results when plotted on the same axes. There is a notable difference in the number of cycles to failure as the tubule orientation increases. It is also revealed that the developed model could forecast for any tubule orientation and be adopted for both young and old teeth.

Black Models

The authors report the results of a 2 × 3 factorial experiment which measures high and low prejudice white consumers’ evaluations of ads for which models’ race is manipulated. The study disconfirms the results of a previous study which differ substantially from those of the general body of literature on the effects of black models. The response of consumers to black models is found to be consistent with previous research findings.

Music Stimulus

This 26 factorial experiment investigated the primacy effect in the orienting response. The type of stimuli (tone or “music”), stimulus intensities (loud or soft), length of adaptation period (same, 5 or 30 sec.; or different, 5 min.), interstimulus intervals (5 or 30 sec.), and sex were studied. College students, 32 males and 32 females were randomly assigned to each group. In the same condition, the tone (or music) was soft (or loud) for 5 sec. (or 30 sec.) in adaptation and was then changed alternately without interruption to loud, soft, etc. (or soft, loud, etc.) for 5 sec. (or 30 sec.). The different condition was identical except for the length of the adaptation period in which the stimuli sounded continuously for 5 min. Analyses of the GSR manifestation of the orienting responses indicated: (a) an over-all primacy effect with the auditory stimuli and (b) the primacy effect occurred in the 5-sec.-same but not in the 30-sec.-same condition as predicted.
