Development of mobile app for electromagnetic wave
No full textElectromagnetic waves are very common in our life, and it is the important part of many technologies, and also the part of the basic knowledge of physics. However, because it is not visible in life and its theoretical knowledge is abstract, it's not easy for beginners to understand. So, we develop an APP to show how electromagnetic wave vertically propagates through three different media, and how to calculate the electromagnetic wave correlation model. This APP can enable students to have a deeper understanding of the propagation of electromagnetic wave and help students make relevant calculations.Master of Science (Communications Engineering

No full textIdentification of Nitric Oxide Responsive Genes in the Rudimentary Leaves of Litchi chinensis
No full textLitchi (Litchi chinensis Sonn.) is an evergreen woody fruit tree widely cultivated in subtropical and tropical regions. Warm winter and hot spring often leads to abnormal floral differentiation in litchi. Under this condition, the rudimentary leaves in the floral buds expand and the inflorescences will stop developing. Thus, how to promote abortion of rudimentary leaves in litchi inflorescence are important for floral development. Previous study indicated that nitric oxide (NO) produced by sodium nitroprusside (SNP) promoted flowering and abortion of rudimentary leaves in litchi. In the present study, a suppression subtractive hybridization (SSH) was used to identify NO responsive genes. As a result, 16 high homologous ESTs were obtained from the SSH library of the SNP treated rudimentary leaves. The ESTs were classified into three groups. They are disease/defensive, protein destination and storage, and protein synthesis. Quantitative reverse transcription PCR (qRT-PCR) analysis indicated that 6 out of the 7 randomly selected ESTs’expression showed an increasing trend from 0 h to 10 h of SNP treatment. It is suggested that the litchi homologs 18S ribosomal RNA gene, cytochrome P450 like TBP, and the senescence-associated protein, chaperone protein, and a hypothetical protein encoding genes may be involved in the NO-induced senescence in litchi rudimentary leaves. LcERD15-like may be a key gene involved in this process.</jats:p
Identification of Chilling-Responsive Genes in Litchi chinensis by Transcriptomic Analysis Underlying Phytohormones and Antioxidant Systems
No full textLitchi (Litchi chinensis Sonn.) is an important subtropical and tropical evergreen fruit tree that is seriously affected by chilling stress. In order to identify genes that may be involved in the response to chilling in litchi, we investigate the physiological and biochemical changes under chilling stress and construct 12 RNA-Seq libraries of leaf samples at 0, 4, 8, and 12 days of chilling. The results show that antioxidant enzymes are activated by chilling treatments. Comparing the transcriptome data of the four time points, we screen 2496 chilling-responsive genes (CRGs), from which we identify 63 genes related to the antioxidant system (AO-CRGs) and 54 ABA, 40 IAA, 37 CTK, 27 ETH, 21 BR, 13 GA, 35 JA, 29 SA, and 4 SL signal transduction-related genes. Expression pattern analysis shows that the expression trends of the 28 candidate genes detected by qRT-PCR are similar to those detected by RNA-Seq, indicating the reliability of our RNA-Seq data. Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis of the RNA-Seq data suggests a model for the litchi plants in response to chilling stress that alters the expression of the plant hormone signaling-related genes, the transcription factor-encoding genes LcICE1, LcCBFs, and LcbZIPs, and the antioxidant system-related genes. This study provides candidate genes for the future breeding of litchi cultivars with high chilling resistance, and elucidates possible pathways for litchi in response to chilling using transcriptomic data
model bimbingan dan konseling dalam menghadapi era 5.0
No full textNow we enter the era of 5.0 or society, where the era of 5.0 is more focused on HR, a striking difference from the previous era made many new changes, one of which is the model of guidance and counseling. The purpose of the article is to provide information regarding the type of guidance and counseling model suitable for dealing with era 5.0 and the benefits of using each of the guidance and counseling models. The method used is a qualitative method, which means how we analyze a problem that occurs. Analyzing suitable and unsuitable guidance and counseling models related to the effectiveness, benefits, and results of the guidance and counseling process. Based on the hypothesis the author states that there is a new guidance and counseling model that will later focus on the potential of students and comprehensive guidance models. and also the existence of this article the public is able to especially in the guidance and counseling profession to know the changes in the model of guidance and counseling according to his time and apply them
Effects of Abscisic Acid on Antioxidant Systems of <i>Stylosanthes guianensis</i> (Aublet) Sw. under Chilling Stress
No full textDrought Stress Induces Flowering and Enhances Carbohydrate Accumulation in Averrhoa Carambola
No full textStar fruit (Averrhoa carambola) is an important fruit tree in tropical and subtropical Asia. The tree blooms several times and fruits accordingly within one year. Controlling the flowering time and understanding the physiological mechanism of the induction of floral buds in A. carambola are indispensable to the industry. In this study, A. carambola potted trees were subjected to drought stress in a growth chamber. To avoid excessive drought stress and leaf abscission, trees were watered every 7 d and were sprayed with water every 2 d. The flowering rate was recorded, and the carbohydrate contents of the leaves, phloem, and xylem tissues were determined during the treatment and after re-watering. The results showed that drought stress increased the flowering rate in both drooping and water shoots, increased the relative conductivity, decreased the relative water content (RWC) of leaves. The total soluble sugar, sucrose, fructose, and glucose in leaves of the drooping shoots were increased. The starch contents in the xylem of both drooping and water shoots were also increased by the treatment. The results indicated that drought stress enhances carbohydrate accumulation in A. carambola. This study provides a potential way by water control to induce flowering without chemical in A. carambola
