A NEW METHOD FOR REGULARIZING A HEAT INVERSE PROBLEM WITH TIME DEPENDENT COEFFICIENT IN THE TWO-DIMENSIONAL CASE
Get PDFIn this paper, we consider an inverse problem with a time-dependent coefficient. This problem is ill-posed. To regularize this problem, we use the integral truncation method combined with the quasi-boundary value method. We construct approximate solutions and consider the stability of such a solution. Moreover, we evaluate the errors between regularized solutions and exact solutions. A numerical method is given to illustrate the theoretically obtained results.In this paper, we consider an inverse problem with a time-dependent coefficient. This problem is ill-posed.

OTOLITH MORPHOLOGY DIVERSITY OF NINE SPECIES OF GOBIES (ACTINOPTERII: GOBIIFORMES) IN THE BA LAT ESTUARY, VIET NAM
Get PDFOtoliths are located in the inner ear of bony fishes, which represent species-specific morphology. Thus, these structures could be used as an important trait in fish identification. However, little such information is available on gobies, one of the most diverse bony fish groups, which are commonly difficult to identify using external morphology. The present study provides information on the otolith morphometry of nine species of gobies (in three families, i.e., Eleotridae, Gobiidae, and Oxudercidae) caught in the Ba Lat estuary of the Red River in 2019. Otolith morphology of species in one family resembles, but it is clearly different between species in the same genus. Otolith length and weight changed proportionally to the fish’s growth, but their shapes were not much changeable in one species. These results are valuable for further investigations into a taxonomy of gobies using otoliths and confirm the species-specific characteristics of this structure in fish identification.Otoliths are located in the inner ear of bony fishes, which represent species-specific morphology.

PREDICTION OF DUPLICATION EVENTS IN THE PLATZ TRANSCRIPTION FACTOR IN CASSAVA (Manihot esculenta) SUGGESTS THE VARIATION OF THEIR FUNCTIONS IN DROUGHT CONDITION
Get PDFThe plant A/T-rich protein and zinc-binding protein (PLATZ) family has been regarded as one of the important plant-specific transcription factors that are involved in various biological processes during evolution. Unfortunately, the expansion of this gene family in cassava (Manihot esculenta) is hardly recognized. This recent work aims to explain the evolution of the MePLATZ gene family by using various bioinformatics tools. Based on the similarity, a total of eight duplicated MePLATZ genes, including seven duplicated pairs and one pair of three duplicated genes have been predicted in the MePLATZ gene family in cassava. Among them, segmental and tandem duplication events were noted to play a crucial role in the expansion of the MePLATZ gene family. We found that the majority of members of the MePLATZ genes contained three or four exons, while at least 10 conserved motifs have been found in the full-length protein sequences. Next, the MePLATZ family could be categorized into seven different groups similar to those described in the PLATZ family in other higher plant species. Interestingly, the expression levels of 17 duplicated MePLATZ genes in leaf samples under drought conditions suggested the hypothesis of the functional conservation, redundancy, and divergence that occurred in this family. Taken together, our study could provide a foundation to get insight into the MePLATZ gene family in cassava.

Using appropriate teaching methods to improve students’ learning results is important in universities. This study points out measures to improve the effectiveness of group discussion methods in teaching and learning the History of the Communist Party of Vietnam curriculum at Hanoi National University of Education. The quantitative paradigm was used, through which an experimental design was applied to the experimental group. Convenience sampling was used to collect 383 students in the experimental group and 187 students in the control group. The data was collected by using pre- and post-test examinations, and a validated questionnaire. The results showed that the group discussion method improved students\u27 interests and learning outcomes. The lecturer had the main role in controlling the group discussion while the students were still the center of the group discussion. The students were encouraged and properly directed to participate in group discussions by dividing the class into small groups (8-10 students/group) discussing the same topic; informing students in advance about the discussion topic; correcting the students’ presentation of their opinions in class; helping the students form ideas during the discussion; and bringing out discussion topics close to the students\u27 preferred choice
