Determinants of Marketability for Organic Biomass Liquid Fertilizer from Human Waste in Da Nang City, Vietnam

引用

Journal of Environmental Protection 2017年第11期8卷 1354-1371页

作者： Buixuan hong Yoshifumi Takahashi Mitsuyasu Yabe Graduate School of Bioresource and Bioenvironmental Science Department of Agricultural and Resource Economics Faculty of Agriculture Kyushu University Fukuoka Japan

Recently, 90 tons of human waste per day are collected from private residences, offices, and public facilities in Da Nang City. Meanwhile, farmers in this region have to allocate 10% - 20% of rice sales for purchasing chemical fertilizer. Therefore, it is essential to be adopted more inexpensive organic fertilizer. To deal with these problems, Japan International Cooperation Agency (JICA) has signed a contract with Da Nang city government about human waste treatment and production of organic biomass liquid fertilizer (OBLF) in 2015. The aims of this project are to promote the use of OBLF in farming and improve public awareness of environmental protection. 530 respondents were interviewed at hoa Vang districts of Da Nang city, and data was analyzed by Contingent Valuation Method (CVM) under double bounded dichotomous choice approach. The results have revealed that 436 respondents (82%) agreed to use OBLF. The farmers’ WTP depends on factors including household income, experience in using organic fertilizer, awareness of environment and training of organic fertilizer in the past. The estimated price for OBLF was 94,856 VND (4.0 USD)/ton. The cost that farmers paid for OBLF was lower than that of current available chemical fertilizers in Da Nang city. this proves that marketability seems to be existed for OBLF product in Da Nang city. From these findings, the government should have policies to support and subsidize the farmers to encourage them to use OBLF in a large scale of cultivation. Furthermore, establishment of a market to consume the organic products harvested from cultivated areas using OBLF is also recommended.

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2018年第11期19卷 863-870页

作者： Bing-hong WANG Ye-sheng XU Wen-jia XIE Yu-feng YAO Department of Ophthalmology Sir Run Run Shaw Hospital Zhejiang University School of Medicine

Objective： To investigate the effects of corneal thickness distribution and apex position on postoperative refractive status after full-bed deep anterior lamellar keratoplasty （FBDALK）. Methods： this is a retrospective analysis of patients who were diagnosed with advanced keratoconus between 2011 and 2014 in our hospital. The base of the cone in all patients did not exceed the central cornea at a 6-mm range. The FBDALK was performed by a same surgeon. All patients had a complete corneal suture removal and the follow-up records were intact. Patients who had graft-bed misalignment or who were complicated with a cataract or glaucoma were excluded. Uncorrected visual acuity （UCVA）, best spectacle corrected visual acuity （BSCVA）, and Pentacam examination data were recorded at two years postoperatively. The recorded data included the superior-inferior （S-I） and nasal-temporal （N-T） corneal thickness differences in 2, 4, 6, and 8 mm diameter concentric circles with the corneal apex as the center （S-I2 mm, S-14 mm, S-I6mm,, S-I8mm, N-T2mm, N-T4 mm, N-T6 mm, and N-T8 mm）, the linear, X-axis, and Y-axis distance between the corneal pupillary center and the cornea apex, total corneal astigmatism at a zone of 3 mm diameter from the corneal apex （TA3 mm）, the astigmatic vector values J0 and J4s, and the corneal total higher-order aberration for 3 and 6 mm pupil diameters （hoa3 mm and hoa6mm）. Statistical analysis was performed by SPSS 15.0. Results： A total of 47 eyes of 46 patients met the criteria and were included in this study. The mean follow-up time was （28±7） months. The mean UCVA was 0.45±0.23 （IogMAR）（MAR： minimum angle of resolution） and the mean BSCVA was 0.19±0.15 （IogMAR）, which were all sig- nificantly positively correlated with postoperative TA3 mm and hoa3 turn. The mean S-I corneal thickness differences were （44.62±37.74） IJm, and the mean N-T was （38.57±32.29） pm. S-12 mm was significantly positively correlated with J0 （r=0.31）, J45 （r=0.42）, hoa3 mm （r=0.37）,

this paper summarizes results of a survey of the operational status of tropical cyclone(TC) forecast verifi-cation in the western North Pacific region, covering the Members of the ESCAP/WMO Typhoon Committee, RSMC Tokyo-Typhoon Center, and JTWC. Results of the survey indicate that significant efforts have been focused on the verification of TC forecast guidance by operational forecast agencies in the region, either individually or through international cooperation. A variety of TC forecast verification products are available to the forecasters in either real time or in post-season through multiple means, with the main focus on the deterministic track and intensity forecasts. Only a few verification products are available for probabilistic forecasts. Verification of TC precipitation and high wind forecasts are also lacking sufficient attention in the region. It would be helpful in the future to focus more attention toward these aspects and incorporate methods that will provide a greater depth of information regarding the TC forecast performance.

AIM： To compare the optical quality after implantation of implantable collamer lens（ICL） and wavefront-guided laser in situ keratomileusis（WG-LASIK）.METHODS： The study included 40 eyes of 22 patients with myopia who accepted ICL implantation and 40 eyes of 20 patients with myopia who received WG-LASIK. Before surgery and three months after surgery, the objective scattering index（OSI）, the values of modulation transfer function（MTF） cutoff frequency, Strehl ratio, and the Optical Quality Analysis System（OQAS） values（OVs） were accessed. The higher order aberrations（hoas） data including coma, trefoil, spherical, 2^（nd） astigmatism and tetrafoil were also obtained. For patients with pupil size 〈6 mm, hoas data were analyzed for 4 mm-pupil diameter. For patients with pupil size ≥6 mm, hoas data were calculated for 6 mm-pupil diameter. Visual acuity, refraction, pupil size and intraocular pressures were also ***： In both ICL and WG-LASIK group, significant improvements in visual acuities were found postoperatively, with a significant reduction in spherical equivalent（P〈 0.001）. After the ICL implantation, the OSI decreasedslightly from 2.34±1.92 to 2.24±1.18 with no statistical significance（P=0.62）. While in WG-LASIK group, the OSI significantly increased from 0.68±0.43 preoperatively to 0.91±0.53 postoperatively（Wilcoxon signed ranks test, P=0.000）. None of the mean MTF cutoff frequency, Strehl ratio, OVs showed statistically significant changes in both ICL and WG-LASIK groups. In the ICL group, there were no statistical differences in the total hoas for either 4 mmpupil or 6 mm-pupil. In the WG-LASIK group, the hoa parameters increased significantly at 4 mm-pupil. The total ocular hoas, coma, spherical and 2^（nd） astigmatism were 0.12±0.06, 0.06±0.03, 0.00±0.03, 0.02±0.01, respectively. After the operation, these values were increased into 0.16±0.07, 0.08±0.05,-0.04±0.04, 0.03±0.01 respectively（Wilcoxon signed ranks test, all P〈0.05）. At 6 mm-pupil, the ind

In this paper, compounds identified in the essential oils obtained by hydrodistillation of the leaves of Cinnamomum glaucescens (Nees) Hand.-Mazz and Cinnamomum verum J.S. Presl (Lauraceae family) of Vietnam origin are reported. The chemical analyses were performed using gas chromatography-flame ionisation detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC-MS). The significant compounds of C. glaucescens were geraniol (36.2%) and terpinen-4-ol (19.7%). On the other hand, C. verum comprised of linalool (22.0%) and bicyclogermacrene (11.2%). The present results may represent new chemotypes of the essential oils of C. verum and C. glaucescens.
