1092-4388(2013/12-0171) II. PURPOSE: This article investigated whether preschool children could adjust their speech rate and articulation clarity based on modeling and explicit instruction by an adult. Two specific hypothesis were investigated in this study: 1) “Do preschoolers align with a model’s speech style and rate? Do these effects persist persist and/or change with exposure?” and 2) Can preschoolers change their speech style and rate when directed?”. III. METHOD: This study consisted of a total of

As a famous songwriter once said‚ “When a woman’s fed up‚ there’s nothing you can do about. It’s like running out of love. No matter what you say‚ it’s too late to talk about it.” Those song lyrics acutely describes Medea’s rage. There was no crime great enough to repay Jason for the hurt and pain he put her through. The character Medea depicts how irrational and extreme a woman can be when she pushed off the edge. Act two opens with what seems to be Medea contemplating: “How did Jason find the

Such peaks include multiple variable peaks ranging from 1200-1300cm-1 that show a Csp2-O oxygen bond that can be inferred for the ether functional group. Additional characteristic peaks include peaks ranging from 1680-1750cm-1 that represents a ketone functional group is present‚ and a broad sharp peak ranging from 3200-3559cm-1 which is indicative of concentrated alcohols and phenols. This is‚ however‚ not supported by the NMR spectra‚ and hence

Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

purple solution turned into damp orange crystals and after thorough drying the crystals were a bright‚ dry and dusty orange. The average melting point range of the final product was 142 °C - 143 °C which corresponded to the melting range of SnI4 143 °C 1. This range was found by doing three trials and then tabulating the average between them (Table

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

CRISPR-Cas9 is a method of gene editing that provides researchers with a way of precisely targeting a specific string of DNA. CRISPR is a sequence of repeated DNA located in the genomes of bacteria that are used in immune systems to help protect our bodies from infecting viruses. This method involves the use of an enzyme known as Cas9 and a guide RNA. A virus’s DNA becomes spacers in the CRISPR sequence when the new virus infects the bacterium. This sequence will then begin the process of transcription
