| 12 | Enhancement of freshwater production of the seawater greenhouse condenser显示文摘Seawater greenhouse(SWGH)is a technology established to overcome issues related to open field cultivation in arid areas,such as the high ambient temperature and the shortage of freshwater.It adopts the humidification-dehumidification concept where evaporated moisture from a saline water source is condensed to produce freshwater within the greenhouse body.Various condenser designs are adopted to increase freshwater production in order to meet the irrigation demand.The aim of this study was to experimentally investigate the practicality of using the packed-type direct contact condenser in the SWGH to produce more freshwater at low costs,simple design and high efficiency,and to explore the impact of the manipulating six operational variables(inlet air temperature of the humidifier,air mass flowrate of the humidifier,inlet water temperature of the humidifier,water mass flowrate of the humidifier,inlet water temperature of the dehumidifier and water mass flowrate of the dehumidifier)on freshwater condensation rate.For this purpose,a direct contact condenser was designed and manufactured.Sixty-four full factorial experiments were conducted to study the effect of the six operational variables.Each variable was operated at two levels(high and low flowrate),and each experiment lasted for 10 min and followed by a 30-min waiting time.Results showed that freshwater production varied between 0.257 and 2.590 L for every 10 min.When using Minitab statistical software to investigate the significant variables that contributed to the maximum freshwater production,it was found that the inlet air temperature of the humidifier had the greatest influence,followed by the inlet water temperature of the humidifier;the former had a negative impact while the latter had a positive impact on freshwater production.The response optimizer tool revealed that the optimal combination of variables contributed to maximize freshwater production when all variables were in the high mode and the inlet air temperature of the humidifier was in the low mode.The comparison between the old plastic condenser and the new proposed direct contact condenser showed that the latter can produce 75.9 times more freshwater at the same condenser volume. | Tahani K BAIT SUWAILAM Abdulrahim M AL-ISMAILI Nasser A AL-AZRI L H Janitha JEEWANTHA Hemesiri KOTAGAMA | 2021 | Journal of Arid Land2021，13，4： | 1 |

| 18 | Water, land, and energy use efficiencies and financial evaluation of air conditioner cooled greenhouses based on field experiments显示文摘High temperature and humidity can be controlled in greenhouses by using mechanical refrigeration cooling system such as air conditioner(AC)in warm and humid regions.This study aims to evaluate the techno-financial aspects of the AC-cooled greenhouse as compared to the evaporative cooled(EV-cooled)greenhouse in winter and summer seasons.Two quonset single-span prototype greenhouses were built in the Agriculture Experiment Station of Sultan Qaboos University,Oman,with dimensions of 6.0 m long and 3.0 m wide.The AC-cooled greenhouse was covered by a rockwool insulated polyethylene plastic sheet and light emitting diodes(LED)lights were used as a source of light,while the EV-cooled greenhouse was covered by a transparent polyethylene sheet and sunlight was used as light source.Three cultivars of high-value lettuce were grown for experimentation.To evaluate the technical efficiency of greenhouse performance,we conducted measures on land use efficiency(LUE),water use efficiency(WUE),gross water use efficiency(GWUE)and energy use efficiency(EUE).Financial analysis was conducted to compare the profitability of both greenhouses.The results showed that the LUE in winter were 10.10 and 14.50 kg/m^(2) for the AC-and EV-cooled greenhouses,respectively.However,the values reduced near to 6.80 kg/m^(2) in both greenhouses in summer.The WUE of the AC-cooled greenhouse was higher than that of the EV-cooled greenhouse by 3.8%in winter and 26.8%in summer.The GWUE was used to measure the total yield to the total greenhouse water consumption including irrigation and cooling water;it was higher in the AC-cooled greenhouse than in the EV-cooled greenhouse in both summer and winter seasons by almost 98.0%–99.4%.The EUE in the EV-cooled greenhouse was higher in both seasons.Financial analysis showed that in winter,gross return,net return and benefit-to-cost ratio were better in the EVcooled greenhouse,while in summer,those were higher in the AC-cooled greenhouse.The values of internal rate of return in the AC-and EV-cooled greenhouses were 63.4%and 129.3%,respectively.In both greenhouses,lettuce investment was highly sensitive to changes in price,yield and energy cost.The financial performance of the AC-cooled greenhouse in summer was better than that of the EV-cooled greenhouse and the pattern was opposite in winter.Finally,more studies on the optimum LED light intensity for any particular crop have to be conducted over different growing seasons in order to enhance the yield quantity and quality of crop. | Ibtihal AL-MANTHRIA Abdulrahim M AL-ISMAILIA Hemesiri KOTAGAMAB Mumtaz KHANC L H Janitha JEEWANTHAD | 2021 | Journal of Arid Land2021，13，4： | 0 |
| 19 | Potential reduction in water consumption of greenhouse evaporative coolers in arid areas via earth-tube heat exchangers显示文摘This study aimed to explore the potential of developing a novel cooling system combining a greenhouse and an earth-tube heat exchanger(ETHE).In this system,greenhouse air is circulated through the underneath soil mass to use the deep-soil cooling effect.This was achieved through the following steps.First,soil temperature profile inside and outside the cultivated greenhouse was monitored for almost one year to study the possibility of using deep-soil coldness for cooling the greenhouse air.Second,a prototype ETHE was built to practically investigate the potential reduction in air temperature as the air flows inside the deep earth pipes.Third,a prototype greenhouse was erected to study the ETHE concept.Results from the first experiment revealed that soil temperature at a soil depth of 2.5 m inside the greenhouse offers good conditions to bury the ETHE.The soil temperature at this soil depth was below the maximum temperature(32℃)that most greenhouse crops can withstand.Results from the prototype ETHE showed a slight reduction in air temperature as it passed through the pipes.From the prototype of the integrated greenhouse and ETHE system,reduction in air temperature was observed as the air passed through the ETHE pipes.At night,the air was heated up across the ETHE pipes,indicating that the ETHE was working as a heater.We concluded from this study that greenhouses in arid climates can be cooled using the ETHE concept which would save a large amount of water that would otherwise be consumed in the evaporative coolers.Further investigations are highly encouraged. | Abdulrahim M AL-ISMAILI Moustafa A FADEL Hemantha JAYASURIYA L H Janitha JEEWANTHA Adel AL-MAHDOURI Talal AL-SHUKEILI | 2021 | Journal of Arid Land2021，13，4： | 0 |
| 20 | Laboratory response to an infant with suspected measles vaccine associated fever and rash in Sri Lanka显示文摘Background:Measles is a highly contagious illness.Sri Lanka(SL)has eliminated the measles in 2019.The coun-try is at risk of importation of measles and there could be vaccine-associated measles like illnesses.Therefore,it is important to investigate patients with fever,rash to differentiate the wild-type from vaccine-type exclud-ing other suspected pathogens to direct infection prevention and control strategies.The objective is to describe the laboratory investigation procedure in an immunocompetent child,developed fever,rash following measles containing vaccine in post-measles eliminated period,SL.Methods:This laboratory based investigation was carried out in National Measles Laboratory,SL.Blood and throat swab were received from a patient with fever,rash,cough and coryza developed at tenth day of receiving the measles containing live-attenuated vaccine.Samples were tested for measles,rubella,and other relevant pathogens according to the laboratory testing algorithm for an immunocompetent child with fever,rash and flu like symptoms.Results:Measles vaccine type A,Edmonston-strain virus was detected after sequencing in throat swab and measles IgM and IgG were positive at sixth-week of illness-onset.In addition,influenza A RNA was detected in throat swab at day-three with detectable parvoB19 IgM in blood sample received at sixth-week of post-onset symptoms.Conclusions:Measles like illness of this immunocompetent child who received measles containing vaccine could be due to measles vaccine-type A or influenza infection.In a measles eliminated,resource-limited setting in SL,there should be a well-defined,testing algorithm to exclude prevalent possible pathogens according to epidemiological and clinical information. | Buddhini Samaraweera Malsha G.Thrimavithana Lakmini Gunathilake Prabath Gankanda Janitha Nanayakkara Janaki I.Abeynayake | 2023 | Infectious Medicine2023，2，1： | 0 |
