Retention measurement techniques: Kim et al [209] ‚used universal testing machine to compared the changes in retentive force of three commercially available attachment systems (Kerator blue‚ O-ring red‚ and EZ lock). The crosshead speed for the simulation was set at 60 mm/min. The lower mounting was seated on the fixed part of this machine‚ while the upper mounting was attached to the operation part. The specimen was placed in a position such that the force could be applied in a perpendicular

Is an average age-equivalent comparison acceptable when comparing a 19 year-old to a 14 year-old or 22 year-old? The answer to the opening question is the basis of this article response paper. Emily Maloney and Linda Larrivee discuss age-equivalent (AE) scores within their article titled‚ “Limitation of Age-Equivalent Scores in Reporting the Results of Nor-Referenced Test.” Speech-language pathologists (SPLs) should not use AE scores based on the list of limitations found in the author’s findings

The results showed that the perometer is not as accurate as the water displacement method and perometer tend to overestimate the lower limb volume as compared to the volumeter. This is in contrast with the studies by Man et al. (2004) and Tierney et al. (1996) where the perometer was found to be as accurate as water displacement. This may be partly explained by the self-protective mechanism of the participants‚ as they seemed slightly sensitive to the “invasiveness” of the perometer frame‚ when the

Results Once the PTC data was collected‚ there were three categories for the experiment which were taster homozygous PAV/PAV‚ taster heterozygous PAV/AVI‚ and a nontaster AVI/AVI. The phenotype I received from the PTC analysis was a heterozygous taster. The data was recorded based on the genotype numbers and the allele frequencies. For

In a study conducted by Ratner and Miller (1959) the topic was to demonstrate classical conditioning with earthworms. The subjects of the experiment were 32 earthworms. In this experiment the unconditioned stimulus was the bright light‚ the conditioned stimulus was the vibration‚ the unconditioned response and the conditioned response was the responsiveness. The earthworms were broken down into four groups by random selection. Presented with the light for 2 seconds‚ which overlapped with the conditioned

In this experiment‚ there seem to be a balance of crickets on each side of the chamber. This show that overtime the crickets will adapt to their environment or the cinnamon has no effect on the crickets at all. This makes sense because crickets are not usually exposed to cinnamon; therefore the cinnamon’s odor should not have a major influence on the crickets’ behavior. This experiment did not account for other species of insect‚ which mean that in some species it may cause a strong interaction between

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

They could turn the lights no and off as they wished. After a month in the room‚ each individual tended to develop a steady cycle. Their cycle at the end of the study was as follows: 25‚ 27‚ 25‚ 23‚ 24‚ 25‚ 26‚ and 25. Using the 5% level of significance‚ what should we conclude about the theory that 24 hours is the natural cycle? (That is‚ does the average cycle length under these conditions differ significantly from the 24 hours?) (a) Use the steps of hypothesis testing. (b) Sketch the distributions
