Do you Hear What I Say? A Phenomenological Exploration of International Students\u27 Oral Communication Experiences with PechaKucha Oral Presentations in a US English for Academic Purposes Program.

With the importance of oral communication skills and digital literacy skills for 21st-century learners (Partnership for 21st Century Skills, 2006), there is an increasing tendency to incorporate technology in language learning and teaching. In this trend, PechaKucha Presentation (PKP), a unique, fast-paced format of giving presentations, has recently been advocated for its benefits in developing learners\u27 oral communication skill in various contexts (Angelina, 2019; Coskun, 2017; Mabuan, 2017). This paper presented a study that explored seven international students\u27 speaking and listening experiences with PKP activities while completing the English for Academic Purposes (EAP) program prior to their undergraduate programs in a US university. The study adopted a phenomenological design with semi-structured interviews, artifacts, and observations. Colaizzi\u27s (1978) data analysis framework was employed to provide a comprehensive description of the participants\u27 speaking and listening experiences with PKP. Findings revealed that (1) participants experienced a connection between emotions regarding PK presentations and their English speaking skills; (2) participants described cognitive and metacognitive skill use and awareness due to PK presentations experiences; (3) participants perceived audience as an important factor in presentation decisions; (4) these EAP international students were aware of and critical of their English- speaking skills; (5) they preferred more time for pronunciation and to convey information; (6) EAP peers\u27 pronunciation hindered meaning making; (7), PK meaning- making processes included listening, reading, viewing, and critiquing their peers\u27 presentation performance. The study also offered several recommendations regarding the most practical teaching strategies that emerged from the findings of this research. Further implications that may inform EAP educators and EAP curriculum designers of oral communication skills for international students were also discussed

The Visible Light Activity of the TiO2 and TiO2:V4+ Photocatalyst

TiO2 and vanadium‐doped TiO2 nanoparticles were synthesized by using the hydrothermal method. The V doping contents are 0.0; 0.1; 0.3; 0.5; 0.7 and 0.9% molar. The vanadium‐doped TiO2 nanoparticles have identical anatase phase with an average crystal size of 10‐20nm. The oleic acid and ethanol solvents with different molar concentrations can make spherical nanograins, or stick form grains, which influence the photo activity of the materials. The absorption spectra of doped samples exhibited long-tailed absorption in the visible light region above 380nm. The visible light photocatalytic activity was evaluated by the degradation of phenol aqueous solutions; after 360 min. under the visible irradiation, the normalized concentration of phenol decreased to 9%

Decoding the capability of Lactobacillus plantarum W1 isolated from soybean whey in producing an exopolysaccharide

This study aims at producing exopolysaccharides (EPS) from a lactic acid bacterial strain. The soybean whey-isolated Lactobacillus plantarum W1 (EPS-W1), which belongs to genus Lactobacillus, is identified using the phenylalanyl-tRNA sequencing method. Of all the examined strains, R-49778 (as numbered by BCCM/LMG Bacteria Collection, Ghent University, Belgium) showed the highest capability of producing exopoly-saccharides. Structural characterization revealed a novel exopolysaccharide consisting of repeating units of -> 6)-D-Glcp-(1 ->; -> 3)-D-Manp-(1 ->; -> 3)-6-Glcp-(1 -> and a branch of -> 6)-D-Manp-(1 ->; -> 2)-D-Glcp-(1 ->. This discovery opens up avenues for the production of EPS for food industries, functional foods, and biomedical applications

Novel exopolysaccharide produced from fermented bamboo shoot-isolated Lactobacillus fermentum

This study aimed at providing a route towards the production of a novel exopolysaccharide (EPS) from fermented bamboo shoot-isolated Lactobacillus fermentum. A lactic acid bacteria strain, with high EPS production ability, was isolated from fermented bamboo shoots. This strain, R-49757, was identified in the BCCM/LMG Bacteria Collection, Ghent University, Belgium by the phenylalanyl-tRNA synthetase gene sequencing method, and it was named Lb. fermentum MC3. The molecular mass of the EPS measured via gel permeation chromatography was found to be 9.85 × 104 Da. Moreover, the monosaccharide composition in the EPS was analyzed by gas chromatography–mass spectrometry. Consequently, the EPS was discovered to be a heteropolysaccharide with the appearance of two main sugars—D-glucose and D-mannose—in the backbone. The results of one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance spectroscopy analyses prove the repeating unit of this polysaccharide to be [→6)-β-D-Glcp-(1→3)-β-D-Manp-(1→6)-β-D-Glcp-(1→]n, which appears to be a new EPS. The obtained results open up an avenue for the production of novel EPSs for biomedical applications

MACRO-ZOOPLANKTON ABUNDANCE IN RELATION TO METAL ACCUMULATION AND WATER QUALITY IN TRUC BACH LAKE

Urban lake pollution is one of the serious issues due to suffering of waste discharged from householders. However, there is a gap of knowledge about the diversity of zooplankton species and how metals accumulate in zooplankton in urban ecosystems. We addressed this by determining the rule of blooming macro-zooplankton in Truc Bach lake and levels of two essential metals: copper (Cu), and zinc (Zn) and of three non-essential metals: arsenic (As), and lead (Pb) in water samples were determined. The results showed that Cladocerans and copepods are macro-zooplankton dominant species in Truc Bach Lake. Water temperature significantly affects the variety of copepod blooming. Arsenic concentration in water collected from the lake exceeded the safety level of current Vietnamese regulation. As concentration in macro-zooplankton positively correlated with metal concentrations in the water (p 0.05) while the concentration of Cu, Zn, and Pb in water has no significant correlation with the metal in zooplankton’s body. The relative abundance of adult copepods in Truc Bach lake had a negative correlation with As concentration in water (p = 0.01). The higher As concentration in water, the lower relative abundance of copepods was found in the sample
