Investigating learners’ English reading and writing skill enhancement using a framework of strengthening Ideal L2 Self for Vietnamese English-majored undergraduates
This study investigates the degree to which the first-year English-majored students’ reading and writing skills were enhanced and how they perceived their skill enhancement after the treatment of the Visionary Motivational Process (VMP) was integrated into the existing course of reading and writing at a university in Vietnam. Employing the theory of L2 Motivational Self System (L2 MSS) (Dörnyei, 2009) accompanied with the workable visionary enhancement activities (Hadfield and Dörnyei, 2013) in building up and developing students’ Ideal L2 self, this paper’s primary purposes comprise enhancing students’ language skills as regards reading and writing skills and exploring their perceptions towards the skill development through the intervention of the VMP. With the mixed methods used, the quantitative data (pre/post-test), and the qualitative data (learner diary) both revealed students’ reading and writing skills were significantly enhanced after the VMP, and notably, students’ perceptions towards the skill enhancement were recorded positively and mainly focused on ‘learning satisfaction’ in their learning and ‘motivational value’ of the VMP lesson plan

NONLINEAR PROPERTIES OF STRUCTURAL HETEROGENEOUS PHOTONIC CRYSTAL FIBERS WITH As2Se3 SUBSTRATE
We examine the possibility of improving the nonlinear properties of photonic crystal fibers (PCFs) with As2Se3 substrates by creating a difference in the diameters of the air holes of the rings around the core. With the new design, all-normal dispersion properties, small effective mode area, high nonlinear coefficient, and low confinement loss were achieved in the long-wavelength range of 2.0–7.0 µm. The highest nonlinear coefficient is 4414.918 W-1.km-1 at 4.5 µm for the lattice constant (Ʌ) of 3.0 µm and the filling factor (d/Ʌ) of 0.85, while the lowest loss is 1.823´10-21 dB/cm with Ʌ = 3.5 µm and d/Ʌ = 0.8. Based on the numerical simulation results, the characteristics of two optimal structures have been analyzed in detail to guide the application in supercontinuum generation

Arsenate reductase gene from Pityrogramma calomelanos L. enhances tolerance to arsenic in tobacco
Arsenic (As) contamination in soil, water and air is an alarming issue worldwide and has serious effects on human health and environment. Arsenic is a naturally occurring element found in rocks, soil, and water, and exposure to high levels of arsenic can lead to a range of health problems. The effects of arsenic contamination can also be felt in the environment, as it can harm plants and animals and disrupt ecological systems. The major purpose of this study was to produce transgenic plants with improved tolerance to and accumulation of arsenic via transformation of arsenate reductase gene (ArsC) into tobacco genome. Transgenic plants were screen by PCR and southern blot. Further, their tolerance and accumulation to arsenic were evaluated. In the result, we have cloned, characterized, and transformed the ArsC gene from Pityrogramma calomelanos L. (PcArsC). Its phylogenetic analysis revealed 99% homology to ArsC gene in GenBank (accession number X80057.1). Moreover, Southern blot analysis showed that ArsC gene was integrated into the tobacco genome as a single-copy. These single-copy transgenic lines showed much higher tolerance to and accumulation of As than wild type, with no other phenotypes observed. These results demonstrated that Pityrogramma calomelanos ArsC gene can improve arsenic tolerance and accumulation in transgenic tobacco lines. Thus, using Pityrogramma calomelanos L. ArsC gene for genetic engineering has potential implications in the decontamination of arsenic-containing soil

Nonlinear post-buckling of thin FGM annular spherical shells under mechanical loads and resting on elastic foundations
This paper presents an analytical approach to investigate the nonlinear buckling and post-buckling of thin annular spherical shells made of functionally graded materials (FGM) and subjected to mechanical load and resting on Winkler-Pasternak type elastic foundations. Material properties are graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of constituents. Equilibrium and compatibility equations for annular spherical shells are derived by using the classical thin shell theory in terms of the shell deflection and the stress function. Approximate analytical solutions are assumed to satisfy simply supported boundary conditions and Galerkin method is applied to obtain closed-form of load-deflection paths. An analysis is carried out to show the effects of material and geometrical properties and combination of loads on the stability of the annular spherical shells
Communication activities of students with the social cultural environment during floods: A case study in Thua Thien Hue province, Vietnam
This study aims to explore the variances in communication behaviours among undergraduate students within the social-cultural context. A total of 104 participants (40 lecturers and six managers) were selected from two universities, namely Hue University of Science and Hue University of Education. The collected data was subsequently evaluated. The findings suggest that there are slight differences between male and female students. This study highlights significant differences in involvement among Kinh ethnic students and students from other ethnic groups. Furthermore, the geographical location and sociocultural environment of a region significantly influence the communication behaviors and preferences of students. Students demonstrate higher mean scores in diverse communication activities as compared to lecturers. The results highlight the significance of gender, ethnicity, geographic location and student status in influencing students' participation in communication. Recognizing and addressing these differences can help in the development of effective communication strategies, the development of inclusive environments and the encouragement of positive social interactions among various groups of students. The implications for students' well-being, academic success and intercultural competency might be explored in more detail in further studies by examining the fundamental variables that lead to these differences
Preliminary establishment of a multiplex PCR method for the identification of pork and beef meat based on cytochrome-B Gene
Molecular species detection in food has become common in the last years. In this study, multiplex PCR (mPCR) technique was applied to discriminate between the pork and beef with the aim of detecting the pork in food products made from beef. We developed a m-PCR protocol detected the presence of pork in food products made from beef based on Cytochrome-b gene by a general primer pair F and primer pair (RP, RC), specific two private with pig and cow. The m-PCR method was successfully designed with technical parameters, such as the annealing temperature of 590C and the final concentration of each primer in a reaction of 0,4µM. The minimum DNA concentration of pig and cow could be detected by m-PCR, which was 0,1ng/µl. This process was tested on 24 different beef sausage samples tagged no pork, resulting in 11/24 (46%) of samples, were found the presence of pork and 54% (13/24) of samples no beef and pork. According to this sequencing result that are completely accordant, we affirm primer-specific amplification in this study can be applied to experiment on large number of sample and the ton other types food made from beef
