Light field displays comprise three-dimensional （3D） visual information presentation devices capable of providing realistic and full parallax autostereoscopic images. In this letter, the recent advances in the light field displays based on integral imaging （II） and holographic techniques are presented. Several advanced approaches to demonstrate the light field displays including viewing angle enhancement techniques of the II display, a fast hologram generation method using graphics processing unit （GPU） and multiple WRPs, and a holographic microscopy to display the living cells are reported. These methods improve some important constraints of the light field displays and add new features.

Advances in Bioscience and Biotechnology 2016年第10期7卷 418-427页

作者： phan Van Tan Faculty of Agriculture and Forestry Taynguyen University Buonmathuot city Vietnam

A rapid and improved micropropagation protocol was developed for Curcuma sp., a threatened and high value medicinal plant, using main bud sprout and top of rhizome sprout as explants. Stepwise optimization of different plant is to change the growth regulator, reduce the level of macro-nutrition and add humate. The present study has created multiple shoot and root induction and plantlet in vitro culture, transfers the plantlet to ex vitro. The M2 medium (MS’s macronutrition 1/4, MS’s micronutrition + Morel’s vitamine + coconut milk 10% + sucrose 25 g/l + humate 1.0 ml/l + agar 7.5 g/l + 2,4D 0.5 mg/l + BAP1.0 mg/l + TDZ 1.0 mg/l) is the highest ratio of callus induction. The TA3 medium (MS’s macronutrition 1/4 + MS’s micronutrition + Morel’s vitamin+ coconut milk 10% + sucrose 25g/l + humate 2.0 ml/l + 2,4 D 0.5 mg/l + kinetin 2.0 mg/l + TDZ 1.0 mg/l + BAP 1.0 mg/l2 + nAA 2.0 mg/l + activated carbon 2.0 g/l) is able to create buds and regeneration multiple bud for Curcuma sp. TA3 medium adding IAA 2 mg/l and IBA 0.5 mg/l has resulted in the highest indices of quantity, healthy shoot and large diameter of roots. A large number of healthy plantlets are induced by the medium of MS’s macronutrients 1/2, MS’s micronutrients full, Morel’s vitamin, humate 3 g/l, coconut milk 150 ml/l, activated carbon 3 g/l, composition phytohormone: IAA 2 mg/l + BAP 2 mg/l + TDZ 0.5 mg/l. Further studies should focus on optimizing the humate concentration for these species of Zingiberaceae. The duration of the research is from 5/2015 to 4/2016 at Faculty of Agriculture and Forestry, Tay nguyen University, Vietnam.

However, it is more challenging to demonstrate an evidence based rationale supporting the indications of PCI in these lesions.

The Evaluation of Land Use Changes on Stream Discharge by SWAT Model and Remote Sensing in Agro-Forestry Watershed： A Case Study in nghinh Tuong Subwatershed, northern Vietnam

引用

Journal of Agricultural Science and Technology(A) 2015年第2期5卷 99-105页

作者： phan Dinh Binh Faculty of Resources Management Thai Nguyen University of Agriculture and Forestry Thai Nguyen City 0280 Vietnam

The purpose of this paper was to implement ＂Soil and Water Assessment Tool （SWAT）＂ model and Geographic Information System （GIS） to evaluate the impact of land use changes on stream discharge in nghinh Tuong watershed （a brand of Cau River） in northern Vietnam. The watershed was coverd by 56% forestry land, 30% agricultural land and the remain 14% for others. Stream discharge observed data from 2002 to 2007 were used for calibration period and from 2008 to 2012 for validation period. The result showed that two coefficients （nSE and PBIAS） to evaluate model performance were 0.76 and 6.54% for calibration period and 0.87 and 4.74% for validation period, respectively. Stream discharge strongly depends not only on quantity of precipitation but also on land use change. Through the scenario 1, agricultural land （corn, orchard and tea） increases 9,782.67 ha （2.45%）, meanwhile forest （forest-mixed） decreases 1,091.77 ha （2.75%） as compared to baseline scenario. Additionally, precipitation increases 3.74% in mean wet season, but decreases 0.5% in mean dry season with respect to baseline period. SWAT model was able to simulate stream discharge and sediment yield for nghinh Tuong watershed successfully not only for baseline scenario but also for scenario 1. In brief, SWAT proves its ability in simulation stream discharge in subwatershed level. It is a useful tool to assist water quantity and quality management process in nghinh Tuong watershed. This work one more time indicated that SWAT is useful tool for resources and environment management.
