<p class="TTPAbstract">In this study, 2-dimensional Brazil nut effect experiments were setup. An intruder moves from its initial position at the middle-bottom of a container to its final position at the top of the granular bed. To predict the motion of the intruder, the number of contact points for each grain around the intruder was counted manually for grains in the first layer until the third layer. The average numbers of contact points from grains in each of 8 directions respected to the center of the intruder were calculated to determine the direction of total force acting on the intruder by grains in the first layer, in the first two-layers, and in the first three-layers.The result will be more acceptable using the data of two or three layers of grains in predicting intruder movement.</p>

The purpose of this research was to analyze the third semester students’ problem in learning English basic sounds pronunciation. The research design was case study. The data were collected by recording the students’ pronunciation. The subject of the research were the third Semester Students of English Department at Universitas Ekasakti). The result of the research was found that Each aspirated /p/, /t/, /k/ have two allophones, [ph] and [p], [th] and [t], [kh] and [k]. Then, all instances of [ph] occured immediately before a stressed vowel. It can be said that the following rule: /p/ becomes [ph] when it occured before a stressed vowel or initial position of English words. Moreover, aspirated /p/, /t/, /k/ sounds were really pronounced in two different ways. First, when these sounds came at the beginning of the word they are always followed by a puff of breath. Second, if aspirated /p/, /t/, and /k/ occur at the end of final position of English words, it is not necessary to pronounce them by following a puff of breath. In following there is a chart of aspirated /p/, /t/, /k/ sounds at initial position of English words

Sound Learning

3 groups of naive adults were tested on their pronunciations of a foreign sound after one received no phonetic pretraining, another practiced the sound in the initial position, and the third learned it in the final. A significant positive transference effect indicated that practicing an unknown sound in the initial position facilitates its pronunciation in the final position.

In the Southern Bavarian variety of Tyrolean, laryngeal contrasts undergo a typologically interesting process of neutralisation in word-initial position. We undertake an acoustic analysis of Tyrolean stops in word-initial, word-medial intersonorant and word-final contexts, as well as in obstruent clusters, investigating the role of the acoustic parameters VOT, prevoicing, closure duration and F0 and H1–H2* on following vowels in implementing contrast, if any. Results show that stops contrast word-medially via [voice] (supported by the acoustic cues of closure duration and F0), and are neutralised completely in word-final position and in obstruent clusters. Word-initially, neutralisation is subject to inter- and intraspeaker variability, and is sensitive to place of articulation. Aspiration plays no role in implementing laryngeal contrasts in Tyrolean.
