( Vu,N. T. ),( J. M. Park ),( A. T. Tran ),( T. K. Bui ),( D. C. Vu ),( D. C. Jang ),( I. S. Kim ) 강원대학교 농업생명과학연구원(구 농업과학연구소) 2018 강원 농업생명환경연구 Vol.30 No.3
Water stress effects on the growth and physiology of three coffee species, arabica, robusta, and liberica, were investigated. Unlike in plants that had water supply, plant height, leaf length, and leaf width values decreased significantly in arabica and liberica in a water deficit condition but did not statistically differ in robusta coffee plants. The highest values of reduction in growth characteristics of coffee plants under water deficit condition were observed in arabica, but they did not significantly differ from those in robusta or liberica. The highest value of relative water content in a water deficit condition was observed in liberica, but it was similar to that of robusta. The SPAD value and Fv/Fm of all coffee species decreased significantly during the period without irrigation but increased significantly after re-watering. SPAD values of robusta and liberica in a water deficit condition were higher than those of arabica. The highest value of relative ion leakage during drought was observed in arabica. On the other hand, robusta generally appeared to be more vigorous than arabica and liberica, as shown by its relatively lower percentage of wilting plants and higher percentage of recovering plants.

The objective of this study was conducted to determine effects of grafting position and water content in the substrate on the survival rate and quality of grafted tomato seedlings. Two grafting positions including above and below the rootstock cotyledons were examined. In addition, three water content levels (mid (control), high and low) in thesubstrate were set up during healing and acclimatization processes. There was no difference in survival rate between two grafting positions, but grafting positions effected on growth of grafted seedlings. The growth parameters and root morphology of seedlings grafted above the rootstock cotyledons were higher than that in seedlings grafted below the rootstock cotyledons, except leaf chlorophyll value and T/R ratio. The maximum survival rate (100%) was observed in mid (control) and high water treatments, but the survival rate (95.3%) decreased in low water treatment. The tallest plant height and largest leaf area were obtained in high water treatment. Leaf chlorophyll content significantly increased in low water treatment. No significant difference was detected among different water treatment with stem diameter, number of leaves. Grafted seedling in low water treatment significantly decreased fresh and dry weight of shoot and root. T/R ratio increased in low water treatment, but it was similar in mid and high water treatments. The high compactness value was observed in mid water treatment. The high values of total root surface area, total root length, and number of root tips were observed in high water treatment. However, there was no significant difference between mid (control) and low water treatments on total root surface area, total root length, and number of toot tips.

Bioassays to evaluate the mortality, virulence and reproduction potentials of four indigenous EPN strains, SPQ16, S-BM12, H-KT3987 and H-CB3452 on insect larvae of mealworm (Tenebrio molitor) and greater wax moth (Galleria mellonella) revealed the highest mortality rates of two insect larvae at the highest inoculation dose of 100 IJs to range from 89 to 100 percent and 94.3–100 percent at 48 h after inoculation, respectively. Virulence was high for all nematode strains, with LC 50 values between 29.6 and 47.3 IJs/insect host. The highest IJ yields were different between nematode strains and insect host, from 66.8 × 10 3 IJs (S-PQ16) to 118.6 × 10 3 IJs (HKT3987) on T. molitor, and from 54.2 × 10 3 IJs (S-BM12) to 163.3 × 10 3 IJs (H-KT3987) on G. mellonella. The culturing cost in terms of food expenditure for rearing insect larvae varied between insect larvae and nematode strains, from 6.76 to 26.63 USD per billion IJs for nematode strains cultured on T. molitor larvae and from 3.54 to 7.81 USD per billion IJs for nematode strains cultured on G. mellonella larvae. The full cost for a nematode product of 2.5 × 10 9 IJs per hectare, produced through in vivo mass culturing, of the most efficient nematode strain, H-KT3987, was 191.3 USD, slightly cheaper than 199.4 USD for the same nematode product produced through in vitro mass culturing.

Development of Low-Cost Drive System of a Small-Size Electric Vehicles
T.T.Vu,D.T.Lien,T.W.Chun,H.H.Lee,H.G.Kim,E.C Nho 전력전자학회 2011 ICPE(ISPE)논문집 Vol.2011 No.5
This paper develops the low-cost drive system of the small-size electric vehicles (EVs) driven by the brushed dc motor. The power circuit for driving the dc motor is designed by considering both the cost and efficiency. Some MOSFET and diodes at the power converter are connected in parallel for reducing the conduction loss. In order to change smoothly the rotating direction of dc motor, an operating sequence for both the field current and the armature voltage according to the accelerator pedal angle is suggested. Through the simulation studies and experimental results with the low-cost 8-bit AVR, the performances of the proposed methods are verified.

Heavy metals recovery from Printed Circuit Boards industrial wastewater is crucial because of its cost effectiveness and environmental friendliness. In this study, a copper recovery route combining the sequential processes of acid leaching and LIX 984N extracting with an electrowinning technique from Printed Circuit Boards production's sludge was performed. The used residual sludge was originated from Hanoi Urban Environment One Member Limited Company (URENCO). The extracted solution from the printed circuit boards waste sludge containing a high copper concentration of 19.2 g/L and a small amount of iron (0.575 ppm) was used as electrolyte for the subsequent electrolysis process. By using a simulation model for multi-step current electrolysis, the reasonable current densities for an electrolysis time interval of 30 minutes were determined, to optimize the specific consumption energy for the copper recovery. The mathematical simulation model was built to calculate the important parameters of this process.

Ha, V.T.,Kien, V.T.,Binh, L.H.,Tien, V.D.,My, N.T.T.,Nam, N.H.,Baltas, M.,Hahn, H.,Han, B.W.,Thao, D.T.,Vu, T.K. Academic Press ; Academic Press 2016 Bioorganic chemistry Vol.66 No.-
<P>A series of novel hydroxamic acids bearing artemisinin skeleton was designed and synthesized. Some compounds in this series exhibited moderate inhibition against the whole cell HDAC enzymes. Especially, compound 6g displayed potent cytotoxicity against three human cancer cell lines, including HepG2 (liver cancer), MCF-7 ( breast cancer) and HL-60 (leukemia cancer), with IC50 values of 2.50, 2.62 and 1.28 mu g/mL, respectively. Docking studies performed with two potent compounds 6a and 6g using Autodock Vina showed that both compounds bound to HDAC2 with relatively high binding affinities from -7.1 to 7.0 kcal/mol compared to SAHA (-7.4 kcal/mol). It was found in this research that most of the target compounds seemed to be more cytotoxic toward blood cancer cells (HL-60) than liver (HepG2), and breast (MCF-7) cancer cells.

The objective of this study was to evaluate influence of light-emitting diode (LED) irradiation during grafting period on the survival rate and quality of grafted pepper seedlings. Irradiation by six light treatments (darkness, white fluorescent lamps (WFL), blue LED, red LED, red+blue LED (1:1), far-red LED) was used to treat grafted pepper seedlings for 10 days during healing and acclimatization period. The maximum (100%) survival rate was recorded in red LED and blue+red LED treatments, but it was not statistically different with the WFL treatment. The lowest survival rate was also observed in the darkness treatment. The growth characteristics of grafted seedlings in red LED were similar with those in blue+red LED treatment, but they were greater than those in darkness, WFL, blue LED, and far-red LED treatments. Stem diameter, leaf number, and leaf area were similar between seedlings treated with WFL, blue LED, red LED, and blue+red LED, but they decreased in seedlings treated with darkness and far-red LED. Fresh and dry weight of shoot and root were similar between seedlings treated with red LED and blue+red LED, but they decreased in seedlings treated with WFL, blue LED, far-red LED, and darkness. The lowest of fresh and dry weights of shoot and root were observed in the darkness treatment. Seedlings treated with red LED, blue+red LED, and WFL were significantly more compact than that in darkness, blue LED, and far-red LED treatments. The root morphology was improved in seedlings treated with red LED by increasing total root surface, total root length, and number of toot tips.
