Four synthetic peptides (Peptidyl MIMs; Demeter Biotechnologies, Inc.) were evaluated for their in vitro activity against Acholeplasma laidlawii. Fifty percent effective concentration values ranged from 1 to 15 microM. Three of these compounds are more lethal than cecropin B against A. laidlawii.

A tandem solar cell device whose sub-cells are fabricated exclusively from small molecules (SMs) through both solution-processed and vacuum-processed deposition techniques is described. The front sub-cell's active layer consists of a bulk heterojunction (BHJ) DPP(TBFu)2:PC70BM device while the back cell has a typical bilayer structure employing a 2,4-bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphe...

This paper discusses problems in developing L2 lexical competence in an input-poor environment, and suggests what we can do so as to minimize the negative effects of those problems on L2 lexical learning. As an unavoidable problem, we discussed a learner strategy unequivocally used by Japanese students when learning the meaning of a new word. To enhance L2 lexical learning, we suggested that le...

This position paper highlights the importance of suprasegmental training in secondary language (L2) acquisition. Suprasegmental features are manifested in terms of acoustic cues and convey important information about linguistic and information structures. Hence, L2 learners must harness appropriate suprasegmental productions for effective communication. However, this learning process is influen...

Second language (L2) learners tend to speak slower at every level of linguistic analysis, often in an uneven tempo, with longer pauses at the start and before some words and constructions, than is typical of native speech. As noted by Zhang & Elder [1], native listeners focus on phonological fluency in making judgments about L2 proficiency. Improved understanding of how fluency grows with progr...

Gazing activities during utterances and silence were analyzed in a face-to-face three party conversation setting in a native language (L1) and in a second language (L2). The function of each utterance was categorized (Traum, 1994) so that gazes during utterances could be analyzed from the viewpoint of grounding in communication (Clark, 1996). The result of a factor analysis suggests that langua...

high levels of mental health during studying in university, makes students able to deal effectively with numerous stressors they experience. our aim of this study was to examine and compare social anxiety among first to fourth year student nurses of ministry of health affiliated universities of medical sciences located in tehran city, iran in 2010. in this descriptive analytic study, 400 studen...

The here presented and ongoing study addresses L2 fluency and hesitation phenomena in the context of speech effects in intercultural communication. It investigates the impact of fluency and hesitation phenomena on the perception of non-native speakers by native listeners of German. The first results underline the importance and salience of hesitation phenomena and fluency for speech effects and...
