About 48 soil samples were taken from 0-30, 31-60, 61-90 and 91-120 cm soil depths by opening 12 representative soil profile pits at 1.5 m depth. Soil color, texture, bulk density, Soil Organic Carbon (SOC), Cation Exchange Capacity (CEC), Na, K, Mg, Ca, CaCO<sub>3</sub>, gypsum (CaSO<sub>4</sub>), pH, Sodium Adsorption Ratio (SAR), Exchangeable Sodium Percentage (ESP) were analyzed. The dominant soil texture was silty-clay-loam.  Bulk density varied from 1.1 to 1.31 g/cm<sup>3</sup>. High SOC content was observed in 0-30 cm. The soil pH ranged from 7.1 to 8.6. The electrical conductivity shows indirect relationship with soil depth while CaCO<sub>3</sub> and CaSO<sub>4</sub> concentrations were observed in a direct relationship with depth. About 41% are non-saline, 38.31% saline, 15.23% saline-sodic and 5.46% sodic soils. Na concentration in saline soils was greater than Ca and Mg in all the soil depths. Ca and Mg contents were higher above 60 cm soil depth in non-saline soils. The concentrations of SO<sub>2</sub><sup>-4</sup> and HCO<sup>-3</sup> were observed to be higher at the most lower depth than upper. SAR value tends to be higher at lower depths in saline and saline-sodic soils, but decreases at lower depth of the non-saline soils. The distribution of ESP above 60 cm depth was in an increasing order in saline and saline-sodic soils. The result of the research has shown the direction to which extent of salinity we should consider for the Commiphora plant species we want to grow on the area.  <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commiphora%20species" title="commiphora species">commiphora species</a>, <a href="https://publications.waset.org/abstracts/search?q=dryland%20vegetation" title=" dryland vegetation"> dryland vegetation</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20significance" title=" ecological significance"> ecological significance</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20quality" title=" soil quality"> soil quality</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity%20problem" title=" salinity problem"> salinity problem</a> </p> <a href="https://publications.waset.org/abstracts/123086/soil-quality-status-under-dryland-vegetation-of-yabello-district-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123086.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9254</span> Improvement of Mechanical Properties of Saline Soils by Fly Ash: Effect of Freeze-Thaw Cycles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhuo%20Cheng">Zhuo Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaohang%20Cui"> Gaohang Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Zheng"> Yang Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiqiang-Pan"> Zhiqiang-Pan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To explore the effect of freeze-thaw cycles on saline soil mechanical properties of fly ash, this study examined the influence of different numbers of freezing and thawing cycles, fly ash content, and moisture content of saline soil in unconfined compression tests and triaxial shear tests. With increased fly ash content, the internal friction angle, cohesion, unconfined compressive strength, and shear strength of the improved soil increased at first and then decreased. Using the Desk-Expert 8.0 software and based on significance analysis theory, the number of freeze-thaw cycles, fly ash content, water content, and the interactions between various factors on the mechanical properties of saline soil were studied. The results showed that the number of freeze-thaw cycles had a significant effect on the mechanical properties of saline soil, while the fly ash content had a weakly significant effect. At the same time, interaction between the number of freeze-thaw cycles and the water content had a significant effect on the unconfined compressive strength and the cohesion of saline soil, and the interaction between fly ash content and the number of freeze-thaw cycles only had a significant effect on the unconfined compressive strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title="fly ash">fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=saline%20soil" title=" saline soil"> saline soil</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonally%20frozen%20area" title=" seasonally frozen area"> seasonally frozen area</a>, <a href="https://publications.waset.org/abstracts/search?q=significance%20analysis" title=" significance analysis"> significance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20analysis" title=" qualitative analysis"> qualitative analysis</a> </p> <a href="https://publications.waset.org/abstracts/136606/improvement-of-mechanical-properties-of-saline-soils-by-fly-ash-effect-of-freeze-thaw-cycles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136606.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9253</span> Assessing Water Quality Using GIS: The Case of Northern Lebanon Miocene Aquifer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Saba">M.

A.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Land degradation, a leading environemtnal problem and a decrease in the quality of land has become a major global issue, caused by human activities. By land degradation, more than half of the world’s drylands are affected. The worldwide scope of main saline soils is approximately 955 M ha, whereas inferior salinization affected approximately 77 M ha. In irrigated areas, a total of 58% of these soils is found. As most of the vegetation types requires fertile soil for their growth and quality production, salinity causes serious problem to the production of these vegetation types and agriculture demands. This research aims to identify the salt affected areas in the selected part of Indus Delta, Sindh province, Pakistan. This particular mangroves dominating coastal belt is important to the local community for their crop growth. Object based image analysis approach has been adopted on Landsat TM imagery of year 2011 by incorporating different mathematical band ratios, thermal radiance and salinity index. Accuracy assessment of developed salinity landcover map was performed using Erdas Imagine Accuracy Assessment Utility. Rain factor was also considered before acquiring satellite imagery and conducting field survey, as wet soil can greatly affect the condition of saline soil of the area. Dry season considered best for the remote sensing based observation and monitoring of the saline soil. These areas were trained with the ground truth data w.r.t pH and electric condutivity of the soil samples. The results were obtained from the object based image analysis of Keti bunder and Kharo chan shows most of the region under low saline soil.Total salt affected soil was measured to be 46,581.7 ha in Keti Bunder, which represents 57.81 % of the total area of 80,566.49 ha. High Saline Area was about 7,944.68 ha (9.86%). Medium Saline Area was about 17,937.26 ha (22.26 %) and low Saline Area was about 20,699.77 ha (25.69%). Where as total salt affected soil was measured to be 52,821.87 ha in Kharo Chann, which represents 55.87 % of the total area of 94,543.54 ha. High Saline Area was about 5,486.55 ha (5.80 %). Medium Saline Area was about 13,354.72 ha (14.13 %) and low Saline Area was about 33980.61 ha (35.94 %). These results show that the area is low to medium saline in nature. Accuracy of the soil salinity map was found to be 83 % with the Kappa co-efficient of 0.77. From this research, it was evident that this area as a whole falls under the category of low to medium saline area and being close to coastal area, mangrove forest can flourish. As Mangroves are salt tolerant plant so this area is consider heaven for mangrove plantation. It would ultimately benefit both the local community and the environment. Increase in mangrove forest control the problem of soil salinity and prevent sea water to intrude more into coastal area. So deforestation of mangrove should be regularly monitored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indus%20delta" title="indus delta">indus delta</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20based%20image%20analysis" title=" object based image analysis"> object based image analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20salinity" title=" soil salinity"> soil salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=thematic%20mapper" title=" thematic mapper "> thematic mapper </a> </p> <a href="https://publications.waset.org/abstracts/25891/mapping-potential-soil-salinization-using-rule-based-object-oriented-image-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25891.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">619</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9251</span> Effect of Organic Fertilizers on the Improvement of Soil Microbiological Functioning under Saline Conditions of Arid Regions: Impact on Carbon and Nitrogen Mineralization </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oustani%20Mabrouka">Oustani Mabrouka</a>, <a href="https://publications.waset.org/abstracts/search?q=Halilat%20Md%20Tahar"> Halilat Md Tahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannachi%20Slimane"> Hannachi Slimane </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted on representative and contrasting soils of arid regions. It focuses on the compared influence of two organic fertilizers: poultry manure (PM) and bovine manure (BM) on improving the microbial functioning of non-saline (SS) and saline (SSS) soils, in particularly, the process of mineralization of nitrogen and carbon. The microbiological activity was estimated by respirometric test (CO2–C emissions) and the extraction of two forms of mineral nitrogen (NH4+-N and NO3--N). Thus, after 56 days of incubation under controlled conditions (28 degrees and 80 per cent of the field capacity), the two types of manures showed that the mineralization activity varies according to type of soil and the organic substrate itself. However, the highest cumulative quantities of CO2–C, NH4+–N and NO3-–N obtained at the end of incubation were recorded in non-saline (SS) soil treated with poultry manure with 1173.4, 4.26 and 8.40 mg/100 g of dry soil, respectively. The reductions in rates of release of CO2–C and of nitrification under saline conditions were 21 and 36, 78 %, respectively. The influence of organic substratum on the microbial density shows a stimulating effect on all microbial groups studied. The whole results show the usefulness of two types of manures for the improvement of the microbiological functioning of arid soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salinity" title="Salinity">Salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=Organic%20matter" title=" Organic matter"> Organic matter</a>, <a href="https://publications.waset.org/abstracts/search?q=Microorganisms" title=" Microorganisms"> Microorganisms</a>, <a href="https://publications.waset.org/abstracts/search?q=Mineralization" title=" Mineralization"> Mineralization</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitrogen" title=" Nitrogen"> Nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=Carbon" title=" Carbon"> Carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=Arid%20regions" title=" Arid regions"> Arid regions</a> </p> <a href="https://publications.waset.org/abstracts/21670/effect-of-organic-fertilizers-on-the-improvement-of-soil-microbiological-functioning-under-saline-conditions-of-arid-regions-impact-on-carbon-and-nitrogen-mineralization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21670.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9250</span> Effect of Saline Ground Water on Economics of Bitter-Gourd (Momordica charantia L.)

For this purpose, the effects of saline irrigation on the economics of crop yield and soil salinity should be understood. A two-year field experiment was carried out during 2017-18 with three replications to investigate the effect of saline groundwater on the economics of bitter gourd production and soil salinity status after harvesting the crop. Two irrigation treatments, i.e., fresh quality irrigation water (IT₁ EC 0.56 dS.m⁻¹ (control) and other is saline groundwater ( IT₂ EC 2.56 dS.m⁻¹) were used under drip system of irrigation. Cost-benefit analysis is often used to assess adaptation approaches. In this study, it has been observed that the salts under IT₁ (fresh quality water) and IT₂ (saline groundwater) did not accumulate in the wetted zone. However, the salts were observed deposited at wetted periphery under both the treatments after the crop end at all the three sampling depths under drip system of irrigation. Moreover, the costs and benefits associated with different irrigation treatments for two consecutive seasons for bitter-gourd cultivation were also investigated, and it was found that the average gross returns per hectare in season 1 were USD 5008.22 and 4454.78 under irrigation treatment IT₁ and IT₂ respectively. Whereas in season 2 the average gross returns per hectare were 3713.47 and 3140.51 under IT₁ and IT₂ respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ground-water" title="ground-water">ground-water</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20salinity" title=" soil salinity"> soil salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation" title=" drip irrigation"> drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=wetted%20zone" title=" wetted zone"> wetted zone</a>, <a href="https://publications.waset.org/abstracts/search?q=wetted%20periphery" title=" wetted periphery"> wetted periphery</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20benefit%20analysis" title=" cost benefit analysis"> cost benefit analysis</a> </p> <a href="https://publications.waset.org/abstracts/101836/effect-of-saline-ground-water-on-economics-of-bitter-gourd-momordica-charantia-l-cultivation-and-soil-characteristics-in-semi-arid-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101836.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9249</span> Study of the Efficiency of a Synthetic Wax for Corrosion Protection of Steel in Aggressive Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laidi%20Babouri">Laidi Babouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The remarkable properties of steel, such as hardness and impact resistance, motivate their use in the automotive manufacturing industry. However, due to the very vulnerable environmental conditions of use, the steel that makes up the car body can corrode. This situation is motivating more and more automobile manufacturers to develop research to develop processes minimizing the rate of degradation of the physicomechanical properties of these materials. The present work falls within this perspective; it presents the results of a research study focused on the use of synthetic wax for the protection of steel, type XES (DC04), against corrosion in aggressive environments. The media used in this study are an acid medium with a pH=5.6, a 3% chloride medium, and a dry medium. Evaluation of the protective power of synthetic wax in different environments was carried out using mass loss techniques (immersion), completed by electrochemical techniques (stationary and transient). The results of the immersion of the steel samples, with a surface area of (1.44 cm²), in the various media, for a period of 30 days, using the immersion technique, showed high protective efficiency of synthetic wax in acidic and saline environments, with a lesser degree in a dry environment. Moreover, the study of the protective power, using electrochemical techniques, confirmed the results obtained in static mode (loss of mass), the protective efficiency of synthetic wax, against the corrosion of steel, in different environments, which reaches a maximum rate of 99.87% in a saline environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20wax" title=" industrial wax"> industrial wax</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20techniques" title=" electrochemical techniques"> electrochemical techniques</a> </p> <a href="https://publications.waset.org/abstracts/165660/study-of-the-efficiency-of-a-synthetic-wax-for-corrosion-protection-of-steel-in-aggressive-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9248</span> Experimental Investigation on Freeze-Concentration Process Desalting for Highly Saline Brines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Al-Jabli">H.

A laboratory bench scale freezing technique test unit was designed, constructed, and tested at Doha Research Plant (DRP) in Kuwait. The principal unit operations that have been considered for the laboratory study are: ice crystallization, separation, washing, and melting. The applied process is characterized as “the secondary-refrigerant indirect freezing”, which is utilizing normal freezing concept. The high saline brine was used as definite feed water, i.e. average TDS of 250,000 ppm. Kuwait desalination plants were carried out in the experimental study to measure the performance of the proposed treatment system. Experimental analysis shows that the freeze-melting process is capable of dropping the TDS of the feed water from 249,482 ppm to 56,880 ppm of the freeze-melting process in the two-phase’s course, whereas overall recovery results of the salt passage and salt rejection are 31.11%, 19.05%, and 80.95%, correspondingly. Therefore, the freeze-melting process is encouraging for the proposed application, as it shows on the results, which approves the process capability of reducing a major amount of the dissolved salts of the high saline brine with reasonable sensible recovery. This process might be reasonable with other brine disposal processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20saline%20brine" title="high saline brine">high saline brine</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-melting%20process" title=" freeze-melting process"> freeze-melting process</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20crystallization" title=" ice crystallization"> ice crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=brine%20disposal%20process" title=" brine disposal process"> brine disposal process</a> </p> <a href="https://publications.waset.org/abstracts/62639/experimental-investigation-on-freeze-concentration-process-desalting-for-highly-saline-brines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62639.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9247</span> Interactive of Calcium, Potassium, and Dynamic Unequal Salt Distribution on the Growth of Tomato in Hydroponic System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Koushafar">Mohammad Koushafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hossein%20Khoshgoftarmanesh"> Amir Hossein Khoshgoftarmanesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to water shortage, application of saline water for irrigation is an urgent requirement in agriculture. Thus, this study, the effect of calcium and potassium application as additive in saline root media for reduce salinity adverse effects was investigated on tomato growth in a hydroponic system with unequal distribution of salts in the root media, which was divided into two equal parts containing full Johnson nutrient solution and 40 mM NaCl solution, alone or in combination with KCl (6 mM), CaCl2 (4 mM), K+Ca (3+2 mM) or half-strength Johnson nutrient solution. The root splits were exchanged every 7 days. Results showed that addition of calcium, calcium-potassium and nutrition elements equivalent to half the concentration of Johnson formula to the saline-half of culture media minimized the reduction in plant growth caused by NaCl, although the addition of potassium to culture media was not effective. The greatest concentration of sodium was observed at the shoot of treatments which had the smallest growth. According to the results of this study, in the case of dynamic and non-uniform distribution of salts in the root media, by the addition of additive to the saline solution, it would be possible to use of saline water with no significant growth reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium" title="calcium">calcium</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroponic" title=" hydroponic"> hydroponic</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20salinity" title=" local salinity"> local salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium" title=" potassium"> potassium</a>, <a href="https://publications.waset.org/abstracts/search?q=salin%20water" title=" salin water"> salin water</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a> </p> <a href="https://publications.waset.org/abstracts/16048/interactive-of-calcium-potassium-and-dynamic-unequal-salt-distribution-on-the-growth-of-tomato-in-hydroponic-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16048.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9246</span> Dilution of Saline Irrigation Based on Plant's Physiological Responses to Salt Stress Following by Re-Watering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qaiser%20Javed">Qaiser Javed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Azeem"> Ahmad Azeem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Salinity and water scarcity are major environmental problems which are limiting the agricultural production. This research was conducted to construct a model to find out appropriate regime to dilute saline water based on physiological and electrophysiological properties of Brassica napus L., and Orychophragmus violaceus (L.). Plants were treated under salt-stressed concentrations of NaCl (NL₁: 2.5, NL₂: 5, NL₃: 10; gL⁻¹), Na₂SO₄ (NO₁: 2.5, NO₂: 5, NO₃: 10; gL⁻¹), and mixed salt concentration (MX₁: NL₁+ NO₃; MX₂: NL₃+ NO₁; MX₃: NL₂+ NO₂; gL⁻¹) and 0 as control, followed by re-watering. Growth, physiological and electrophysiology traits were highly restricted under high salt concentration levels at NL₃, NO₃, MX₁, and MX₂, respectively. However, during the rewatering phase, growth, electrophysiological, and physiological parameters were recovered well. Consequently, the increase in net photosynthetic rate was noted under moderate stress condition which was 44.13, 37.07, and 43.01%, respectively in Orychophragmus violaceus (L.) and 44.94%, 53.45%, and 63.04%, respectively were found in Brassica napus L. According to the results, the best dilution point was 5–2.5% for NaCl and Na₂SO₄ alternatively, whereas it was 10–0.0% for the mixture of salts. Therefore, the effect of salinity in O. violaceus and B. napus may also be reduced effectively by dilution of saline irrigation. It would be a better approach to utilize dilute saline water for irrigation instead of applies direct saline water to plant. This study provides new insight in the field of agricultural engineering to plan irrigation scheduling considering the crop ability to salt tolerance and irrigation water use efficiency by apply specific quantity of irrigation calculated based on the salt dilution point. It would be helpful to balance between irrigation amount and optimum crop water consumption in salt-affected regions and to utilize saline water in order to safe freshwater resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dilution%20model" title="dilution model">dilution model</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20growth%20traits" title=" plant growth traits"> plant growth traits</a>, <a href="https://publications.waset.org/abstracts/search?q=re-watering" title=" re-watering"> re-watering</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title=" salt stress"> salt stress</a> </p> <a href="https://publications.waset.org/abstracts/92614/dilution-of-saline-irrigation-based-on-plants-physiological-responses-to-salt-stress-following-by-re-watering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92614.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9245</span> Postoperative Budesonide Nasal Irrigation vs Normal Saline Irrigation for Chronic Rhinosinusitis: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rakan%20Hassan%20M.%20Alzahrani">Rakan Hassan M.

Objective: This article attempted to measure the efficacy of post-operative budesonide nasal irrigation compared to normal saline-alone nasal irrigation in the management of chronic rhinosinusitis (CRS) through a systematic review and meta-analysis of randomized controlled trials (RCTs). Methods: The databases PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched by two independent authors. Only RCTs comparing budesonide irrigation to normal saline alone irrigation for CRS with or without polyposis after functional endoscopic sinus surgery (FESS) were eligible. A random effect analysis model of the reported CRS-related quality of life (QOL) measures and the objective endoscopic assessment scales of the disease was done. Results: Only 6 RCTs met the eligibility criteria, with a total number of participants of 356. Compared to normal saline irrigation, budesonide nasal irrigation showed statically significant improvements in both the CRS-related quality of life (QOL) and the endoscopic findings (MD= -4.22 confidence interval [CI]: -5.63, -2.82 [P < 0.00001]), (SMD= -0.50 confidence interval [CI]: -0.93, -0.06 [P < 0.03]) respectively. Conclusion: Both intervention arms showed improvements in CRS-related QOL and endoscopic findings in post-FESS chronic rhinosinusitis with or without polyposis. However, budesonide irrigation seems to have a slight edge over conventional normal saline irrigation with no reported serious side effects, including hypothalamic-pituitary-adrenal (HPA) axis suppression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budesonide" title="Budesonide">Budesonide</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20rhinosinusitis" title=" chronic rhinosinusitis"> chronic rhinosinusitis</a>, <a href="https://publications.waset.org/abstracts/search?q=corticosteroids" title=" corticosteroids"> corticosteroids</a>, <a href="https://publications.waset.org/abstracts/search?q=nasal%20irrigation" title=" nasal irrigation"> nasal irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=normal%20saline" title=" normal saline"> normal saline</a> </p> <a href="https://publications.waset.org/abstracts/160956/postoperative-budesonide-nasal-irrigation-vs-normal-saline-irrigation-for-chronic-rhinosinusitis-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160956.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9244</span> Hemp Defoliation Technology and Management before Harvesting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rataya%20Yanaphan">Rataya Yanaphan</a>, <a href="https://publications.waset.org/abstracts/search?q=Saksiri%20Kuppatarat"> Saksiri Kuppatarat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarita%20Pinmanee"> Sarita Pinmanee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hemp (Cannabis sativa L. ssp.

This study evaluated chemical defoliants as a means to remove the leaves of hemp before harvest, in an effort to reduce labor expenditures in the production on hemp fiber. This study was conducted by spraying the leaves of hemp with five different treatments: saline solution, Urea (CH4N2O), Ethephon, copper Sulphate (CuSO4) and water (control) before harvesting. The largest percentage of leaf loss 6 days after spraying was with saline solution (43%), followed by Ethephon (32%). However, saline solution also caused drying of the stems but Ethephon did not. Thus, Ethephon was evaluated in the second experiment by spraying with Ethephon concentrations of 0, 10, 15 and 20 ml per 1 liter of water at 7 days before harvest. Spraying with 0.5% Ethephon resulted in 13.6% leaf fall. Spraying with 1.5% and 2% Ethephon resulted in 82.2% and 82.3 % leaf fall, respectively. In addition, using Ethephon to defoliate hemp had no detrimental effect the yield. Therefore, Ethephon concentration at 15 ml per 1 liter of water will be recommended for use in removing hemp leaves by spraying at 7 days before harvest to lower labor cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=defoliation%20technology" title="defoliation technology">defoliation technology</a>, <a href="https://publications.waset.org/abstracts/search?q=ethephon" title=" ethephon"> ethephon</a>, <a href="https://publications.waset.org/abstracts/search?q=hemp%20cultivation" title=" hemp cultivation"> hemp cultivation</a>, <a href="https://publications.waset.org/abstracts/search?q=saline%20solution" title=" saline solution"> saline solution</a> </p> <a href="https://publications.waset.org/abstracts/52525/hemp-defoliation-technology-and-management-before-harvesting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52525.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9243</span> Application Potential of Forward Osmosis-Nanofiltration Hybrid Process for the Treatment of Mining Waste Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ketan%20Mahawer">Ketan Mahawer</a>, <a href="https://publications.waset.org/abstracts/search?q=Abeer%20Mutto"> Abeer Mutto</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Gupta"> S.

Therefore, treatment of wastewater and water recovery is obligatory by any available technology before disposing it into the environment. Currently, reverse osmosis (RO) is the commercially acceptable conventional membrane process for saline wastewater treatment, but consumes an enormous amount of energy and makes the process expensive. To solve this industrial problem with minimum energy consumption, we tested the feasibility of forward osmosis-nanofiltration (FO-NF) hybrid process for the mining wastewater treatment. The FO-NF process experimental results for 0.029M concentration of saline wastewater treated by 0.42 M sodium-sulfate based draw solution shows that specific energy consumption of the FO-NF process compared with standalone NF was slightly above (between 0.5-1 kWh/m3) from conventional process. However, average freshwater recovery was 30% more from standalone NF with same feed and operating conditions. Hence, FO-NF process in place of RO/NF offers a huge possibility for treating mining industry wastewater and concentrates the metals as the by-products without consuming an excessive/large amount of energy and in addition, mitigates the fouling in long periods of treatment, which also decreases the maintenance and replacement cost of the separation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forward%20osmosis" title="forward osmosis">forward osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiltration" title=" nanofiltration"> nanofiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=mining" title=" mining"> mining</a>, <a href="https://publications.waset.org/abstracts/search?q=draw%20solution" title=" draw solution"> draw solution</a>, <a href="https://publications.waset.org/abstracts/search?q=divalent%20solute" title=" divalent solute"> divalent solute</a> </p> <a href="https://publications.waset.org/abstracts/148367/application-potential-of-forward-osmosis-nanofiltration-hybrid-process-for-the-treatment-of-mining-waste-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148367.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">118</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9242</span> Pre-Soaking Application of Salicylic Acid on Four Wheat Cultivars under Saline Concentrations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saad%20M.%20Howladar">Saad M.

Salt affected soils covers 6.73 Mha in India and ~1000 Mha area around the world. Irrigation scheduling of saline water is the way to ensure food security in salt affected areas. Research experiment was conducted at ICAR-Central Soil Salinity Research Institute, Experimental Farm, Nain, Haryana, India with 36 treatment combinations in double split plot design. Three sets of treatments consisted of (i) three regimes of irrigation viz., 60, 80 and 100% (I1, I2 and I3, respectively) of crop ETc (crop evapotranspiration at identified respective stages) in main plot; (ii) four levels of irrigation water salinity (sub plot treatments) viz., 2, 4, 8 and 12 dS m-1 (iii) applications of two PBRs along with control (without PBRs) i.e. salicylic acid (G1; 1 mM) and thiourea (G2; 500 ppm) as sub-sub plot treatments. Grain yield of wheat (Triticum aestivum) was increased with less amount of high salt loaded irrigation water at the same level of salinity (2 dS m-1), the trend was I3>I2>I1 at 2 dS m-1 with 8.10 and 17.07% increase at 80 and 100% ETc, respectively compared to 60% ETc. But contrary results were obtained by increasing amount of irrigation water at same level of highest salinity (12 dS m-1) showing following trend; I1>I2>I3 at 12 dS m-1 with 9.35 and 12.26% increase at 80 and 60% ETc compared to 100% ETc. Enhancement in grain yield of wheat (Triticum aestivum) is not need to increase amount of irrigation water under saline condition, with salty irrigation water less amount of irrigation water gave the maximum wheat (Triticum aestivum) grain yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irrigation%20Scheduling" title="Irrigation Scheduling">Irrigation Scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=Saline%20Environment" title=" Saline Environment"> Saline Environment</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20aestivum" title=" Triticum aestivum"> Triticum aestivum</a>, <a href="https://publications.waset.org/abstracts/search?q=Yield" title=" Yield"> Yield</a> </p> <a href="https://publications.waset.org/abstracts/123899/triticum-aestivum-yield-enhanced-with-irrigation-scheduling-strategy-under-salinity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123899.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9240</span> Ascorbic Acid Application Mitigates the Salt Stress Effects on Helianthus annuus L.

Vit C application at all rates (1, 2 and 3 mM) was significantly increased growth traits, seed and oil yields, and the concentrations of endogenous Vit C, leaf photosynthetic pigments, total soluble sugars, free proline and nutrient elements as well as K/Na ratio. In contrast, Na concentration was significantly reduced with the application of all Vit C levels. Vit C foliar spray at the rate of 2 mM was found to be the best treatment, alleviating the inhibitory effects of salinity on sunflower plants grown on a reclaimed saline soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helianthus%20annuus%20L." title="Helianthus annuus L.">Helianthus annuus L.</a>, <a href="https://publications.waset.org/abstracts/search?q=Vit%20C" title=" Vit C"> Vit C</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20and%20oil%20yields" title=" seed and oil yields"> seed and oil yields</a>, <a href="https://publications.waset.org/abstracts/search?q=osmoprotectants" title=" osmoprotectants"> osmoprotectants</a> </p> <a href="https://publications.waset.org/abstracts/34372/ascorbic-acid-application-mitigates-the-salt-stress-effects-on-helianthus-annuus-l-plants-grown-on-a-reclaimed-saline-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">418</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9239</span> Sustainable Agriculture Practices Using Bacterial-mediated Alleviation of Salinity Stress in Crop Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Trigui">Mohamed Trigui</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Masmoudi"> Fatma Masmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Zouari"> Imen Zouari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Massive utilizations of chemical fertilizer and chemical pesticides in agriculture sector to improve the farming productivity have created increasing environmental damages. Then, agriculture must become sustainable, focusing on production systems that respect the environment and help to reduce climate change. Isolation and microbial identification of new bacterial strains from naturally saline habitats and compost extracts could be a prominent way in pest management and crop production under saline conditions. In this study, potential mechanisms involved in plant growth promotion and suppressive activity against fungal diseases of a compost extract produced from poultry manure/olive husk compost and halotolerant and halophilic bacterial strains under saline stress were investigated. On the basis of the antimicrobial tests, different strains isolated from Sfax solar saltern (Tunisia) and from compost extracts were selected and tested for their plant growth promoting traits, such as siderophores production, nitrogen fixation, phosphate solubilization and the production of extracellular hydrolytic enzymes (protease and lipase) under in-vitro conditions. Among 450 isolated bacterial strains, 16 isolates showed potent antifungal activity against the tested plant pathogenic fungi. Their identification based on 16S rRNA gene sequence revealed they belonged to different species. Some of these strains were also characterized for their plant growth promoting capacities. Obtained results showed the ability of four strains belonging to Bacillus genesis to ameliorate germination rate and root elongation compared to the untreated positive controls. Combinatorial capacity of halotolerant bacteria with antimicrobial activity and plant growth promoting traits could be promising sources of interesting bioactive substances under saline stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abiotic%20stress" title="abiotic stress">abiotic stress</a>, <a href="https://publications.waset.org/abstracts/search?q=biofertilizer" title=" biofertilizer"> biofertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=biotic%20stress" title=" biotic stress"> biotic stress</a>, <a href="https://publications.waset.org/abstracts/search?q=compost%20extract" title=" compost extract"> compost extract</a>, <a href="https://publications.waset.org/abstracts/search?q=halobacteria" title=" halobacteria"> halobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20growth%20promoting%20%28PGP%29" title=" plant growth promoting (PGP)"> plant growth promoting (PGP)</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20fertility" title=" soil fertility"> soil fertility</a> </p> <a href="https://publications.waset.org/abstracts/166274/sustainable-agriculture-practices-using-bacterial-mediated-alleviation-of-salinity-stress-in-crop-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166274.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9238</span> A Comprehensive Study on Cast NiTi and Ti64 Alloys for Biomedical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Mohamed%20Ibrahim">Khaled Mohamed Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A comprehensive study on two biomaterials of NiTi and Ti-6Al-4V (Ti64) was done. Those materials were cast using vacuum arc remelting technique. As-cast structure of Ni-Ti alloy consists of NiTi matrix and some fine precipitates of Ni4Ti3. Ti-6Al-4V alloy showed a structure composed of equiaxed β grains and varied α-phase morphologies. Maximum ultimate compressive strength and reduction in height of 2042 MPa of 18%, respectively, were reported for the cast Ti64 alloy. However, minimum ultimate compressive strength of 1804 MPa and low reduction in height of 3% were obtained for the cast NiTi alloy. Wear rate of both Ni-Ti and Ti-6Al-4V alloys significantly increased at saline solution (0.9% NaCl) condition as compared to dry testing condition. Saline solution harmed the wear resistance of about 2 to 4 times compared to the dry condition. Corrosion rate of NiTi alloy at saline solution (0.9% NaCl) was (0.00038 mm/yr) is almost three times the value of Ti64 alloy (0.000171 mm/yr).

Developing countries’ emissions (such as Malaysia) are now seen to surpass developed country’s emissions due to rapid economic development growth in recent decades. This paper presents the potential storage sites suitability and storage capacity assessment for CO2 sequestration in sedimentary basins of Malaysia. This study is the first of its kind that made an identification of potential storage sites and assessment of CO2 storage capacity within the deep saline aquifers in the country. The CO2 storage capacity in saline formation assessment was conducted based on the method for quick assessment of CO2 storage capacity in closed, and semi-closed saline formations modified to suit the geology setting of Malaysia. Then, an integrated approach that involved geographic information systems (GIS) analysis and field data assessment was adopted to provide the potential storage sites and its capacity for CO2 sequestration. This study concentrated on the assessment of major sedimentary basins in Malaysia both onshore and offshore where potential geological formations which CO2 could be stored exist below 800 meters and where suitable sealing formations are present. Based on regional study and amount of data available, there are 14 sedimentary basins all around Malaysia that has been identified as potential CO2 storage. Meanwhile, from the screening and ranking exercises, it is obvious that Malay Basin, Central Luconia Province, West Baram Delta and Balingian Province are respectively ranked as the top four in the ranking system for CO2 storage. 27% of sedimentary basins in Malaysia were evaluated as high potential area for CO2 storage. This study should provide a basis for further work to reduce the uncertainty in these estimates and also provide support to policy makers on future planning of carbon capture and sequestration (CCS) projects in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20storage" title="CO₂ storage">CO₂ storage</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20saline%20aquifer" title=" deep saline aquifer"> deep saline aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentary%20basin" title=" sedimentary basin"> sedimentary basin</a> </p> <a href="https://publications.waset.org/abstracts/56812/co2-storage-capacity-assessment-of-deep-saline-aquifers-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9236</span> Sensitivity Assessment of Spectral Salinity Indices over Desert Sabkha of Western UAE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rubab%20Ammad">Rubab Ammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelgadir%20Abuelgasim"> Abdelgadir Abuelgasim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> UAE typically lies in one of the aridest regions of the world and is thus home to geologic features common to such climatic conditions including vast open deserts, sand dunes, saline soils, inland Sabkha and coastal Sabkha. Sabkha are characteristic salt flats formed in arid environment due to deposition and precipitation of salt and silt over sand surface because of low laying water table and rates of evaporation exceeding rates of precipitation. The study area, which comprises of western UAE, is heavily concentrated with inland Sabkha. Remote sensing is conventionally used to study the soil salinity of agriculturally degraded lands but not so broadly for Sabkha. The focus of this study was to identify these highly saline Sabkha areas on remotely sensed data, using salinity indices. The existing salinity indices in the literature have been designed for agricultural soils and they have not frequently used the spectral response of short-wave infra-red (SWIR1 and SWIR2) parts of electromagnetic spectrum. Using Landsat 8 OLI data and field ground truthing, this study formulated indices utilizing NIR-SWIR parts of spectrum and compared the results with existing salinity indices. Most indices depict reasonably good relationship between salinity and spectral index up until a certain value of salinity after which the reflectance reaches a saturation point. This saturation point varies with index. However, the study findings suggest a role of incorporating near infra-red and short-wave infra-red in salinity index with a potential of showing a positive relationship between salinity and reflectance up to a higher salinity value, compared to rest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabkha" title="Sabkha">Sabkha</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity%20index" title=" salinity index"> salinity index</a>, <a href="https://publications.waset.org/abstracts/search?q=saline%20soils" title=" saline soils"> saline soils</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat%208" title=" Landsat 8"> Landsat 8</a>, <a href="https://publications.waset.org/abstracts/search?q=SWIR1" title=" SWIR1"> SWIR1</a>, <a href="https://publications.waset.org/abstracts/search?q=SWIR2" title=" SWIR2"> SWIR2</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE%20desert" title=" UAE desert"> UAE desert</a> </p> <a href="https://publications.waset.org/abstracts/77468/sensitivity-assessment-of-spectral-salinity-indices-over-desert-sabkha-of-western-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77468.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">212</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9235</span> Effects of Clozapine and Risperidone Antipsychotic Drugs on the Expression of CACNA1C and Behavioral Changes in Rat ‘Ketamine Model of Schizophrenia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrnoosh%20Azimi%20Sanavi">Mehrnoosh Azimi Sanavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Ghazvini"> Hamed Ghazvini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehryar%20Zargari"> Mehryar Zargari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Ghalehnoei"> Hossein Ghalehnoei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Hosseini-khah"> Zahra Hosseini-khah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Calcium Voltage-Gated Channel Subunit Alpha1 C (CACNA1C) is one of the most important genes associated with schizophrenia. Methods: 45 male Wistar rats were divided into 5 groups: saline, control, ketamine, clozapine, and risperidone. Animals in ketamine, risperidone, and clozapine groups received ketamine (30 mg/ kg-i.p.) for 10 days. After the last injection of ketamine, we started injecting clozapine (7.5 mg/kg-i.p.) risperidone (1 mg/kg-i.p.) for up to 28 days. Twenty-four hours after the last injection, open field, social interaction, and elevated plus-maze tests, and gene expression in the hippocampus were performed. Results: The results of the social interaction test revealed a significant decrease in cumulative time with ketamine compared with the saline group and an increase with clozapine and risperidone compared with the ketamine group. Moreover, results from the elevated plus-maze test demonstrated a critical decrease in open-arm time and an increase in close-arm time with ketamine compared with saline, as well as an increase in open-arm time with risperidone compared with ketamine. Further results revealed a significant increase in rearing and grooming with ketamine compared to saline, as well as a decrease with risperidone and clozapine compared to ketamine. There were no significant differences in CACNA1C gene expression between groups in the rat hippocampus. In brief, the results of this study indicated that clozapine and risperidone could partially improve cognitive impairments in the rat. However, our findings demonstrated that this treatment is not related to CACNA1C gene expression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schizophrenia" title="schizophrenia">schizophrenia</a>, <a href="https://publications.waset.org/abstracts/search?q=ketamine" title=" ketamine"> ketamine</a>, <a href="https://publications.waset.org/abstracts/search?q=clozapine" title=" clozapine"> clozapine</a>, <a href="https://publications.waset.org/abstracts/search?q=risperidone" title=" risperidone"> risperidone</a> </p> <a href="https://publications.waset.org/abstracts/182854/effects-of-clozapine-and-risperidone-antipsychotic-drugs-on-the-expression-of-cacna1c-and-behavioral-changes-in-rat-ketamine-model-of-schizophrenia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182854.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9234</span> Alleviation of Salt Stress Effects on Solanum lycopersicum (L.)

The tomato plant is proven to be moderately sensitive to salt stress. Therefore, two field experiments were conducted using tomato plants (Hybrid 6130) to evaluate the effect of four concentrations of salicylic acid (SA; 0, 20, 40, and 60 µM) applied as foliar spraying in improving plant tolerance to saline soil conditions. Tomato plant growth, yield, osmoprotectants, chloeophyll fluorescence, and ionic contents were determined. The results of this study displayed that growth and yield components and physiological attributes of water-sprayed plants (the control) grown under saline soil conditions were negatively impacted. However, under the adverse conditions of salinity, SA-treated plants had enhanced growth and yield components of tomato plants compared to the control. Free proline, soluble sugars, chlorophyll fluorescence, relative water content, membrane stability index, and nutrients contents (e.g., N, P, K⁺, and Ca²⁺) were also improved significantly, while Na⁺ content was significantly reduced in SA-applied tomato plants. SA at 40 µM was the best treatment, which could be recommended to use for salt-stressed tomato plants to enable them to tolerate the adverse conditions of saline soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tomatoes" title="tomatoes">tomatoes</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title=" salt stress"> salt stress</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorophyll%20fluorescence" title=" chlorophyll fluorescence"> chlorophyll fluorescence</a>, <a href="https://publications.waset.org/abstracts/search?q=dehydration%20tolerance" title=" dehydration tolerance"> dehydration tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=osmoprotectants" title=" osmoprotectants"> osmoprotectants</a> </p> <a href="https://publications.waset.org/abstracts/121930/alleviation-of-salt-stress-effects-on-solanum-lycopersicum-l-plants-grown-in-a-saline-soil-by-foliar-spray-with-salicylic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121930.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">110</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9233</span> Reclamation of Saline and Alkaline Soils through Aquaculture: A Review and Prospects for Future Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Shivakumar">M.

Currently, it is estimated that the 954 mh of saline and alkaline soil is present in the world. Thousands of hectares of land, getting added every year. Argentina, Bangladesh and Australia are most affected countries. In India, out of 142.80 million hectare (mh) cropped area, 56 mh is irrigated area. Of which, more than 9 mh (about 16.%) of land is found to be alkaline/saline. Due to continuous utilization of same land for same agricultural activities, excessive usage of fertilizers and water, most of the soils have become alkaline, saline or water logged. These lands are low productive and at times totally unfit for agricultural activities. These soils may or may not posses good physical condition, but plants may suffer from its inability to absorb water from salty solution. Plants suffer from dehydration and loose water to the soil, shrink, resulting death of plant. This process is called plasmolysis. It is the fact that soil is an independent, organic body of nature that acquires properties in accordance with forces which act upon it. Aquaculture is one of the solutions to utilize such problematic soils for food production. When the impoundments are constructed in an area 10-15% of the affected areas, the excess water along with the salts gets into impoundments and management of salt is easier in water than in the soil. Due to high organic input in aquaculture such as feed, manure and continuous deposition of fecal matter, pH of the soil gets reduced and over the period of time such soils can be put back into the original activity. Under National Agricultural Development Program (NADP), the project was implemented in 258 villages of Mandya District, Karnataka State, India and found that these lands can be effectively utilized for fish culture and increase the proteinacious food production by many folds while conserving the soils. The findings of the research can be adopted and up scaled in any country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saline%20and%20alkaline%20soils" title="saline and alkaline soils">saline and alkaline soils</a>, <a href="https://publications.waset.org/abstracts/search?q=Aquaculture" title=" Aquaculture"> Aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=Problematic%20soils" title=" Problematic soils"> Problematic soils</a>, <a href="https://publications.waset.org/abstracts/search?q=Reclamation" title=" Reclamation"> Reclamation</a> </p> <a href="https://publications.waset.org/abstracts/123393/reclamation-of-saline-and-alkaline-soils-through-aquaculture-a-review-and-prospects-for-future-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123393.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9232</span> Using GIS and Map Data for the Analysis of the Relationship between Soil and Groundwater Quality at Saline Soil Area of Kham Sakaesaeng District, Nakhon Ratchasima, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Thongwat">W.

This region is the one of saline soil area, located in a dry plateau and regularly experience standing with periods of floods and alternating with periods of drought. Especially, the drought in the summer season causes the major saline soil and saline water problems of this region. The general cause of dry land salting resulted from salting on irrigated land, and an excess of water leading to the rising water table in the aquifer. The purpose of this study is to determine the relationship of physical and chemical properties between the soil and groundwater. The soil and groundwater samples were collected in both rainy and summer seasons. The content of pH, electrical conductivity (EC), total dissolved solids (TDS), chloride and salinity were investigated. The experimental result of soil and groundwater samples show the slightly pH less than 7, EC (186 to 8,156 us/cm and 960 to 10,712 us/cm), TDS (93 to 3,940 ppm and 480 to 5,356 ppm), chloride content (45.58 to 4,177,015 mg/l and 227.90 to 9,216,736 mg/l), and salinity (0.07 to 4.82 ppt and 0.24 to 14.46 ppt) in the rainy and summer seasons, respectively. The distribution of chloride content and salinity content were interpolated and displayed as a map by using ArcMap 10.3 program, according to the season. The result of saline soil and brined groundwater in the study area were related to the low-lying topography, drought area, and salt-source exposure. Especially, the Rock Salt Member of Maha Sarakham Formation was exposed or lies near the ground surface in this study area. During the rainy season, salt was eroded or weathered from the salt-source rock formation and transported by surface flow or leached into the groundwater. In the dry season, the ground surface is dry enough resulting salt precipitates from the brined surface water or rises from the brined groundwater influencing the increasing content of chloride and salinity in the ground surface and groundwater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20geology" title="environmental geology">environmental geology</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20salinity" title=" soil salinity"> soil salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20hydrology" title=" groundwater hydrology"> groundwater hydrology</a> </p> <a href="https://publications.waset.org/abstracts/100911/using-gis-and-map-data-for-the-analysis-of-the-relationship-between-soil-and-groundwater-quality-at-saline-soil-area-of-kham-sakaesaeng-district-nakhon-ratchasima-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9231</span> Ordinary Differentiation Equations (ODE) Reconstruction of High-Dimensional Genetic Networks through Game Theory with Application to Dissecting Tree Salt Tolerance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Libo%20Jiang">Libo Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Huan%20Li"> Huan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Rongling%20Wu"> Rongling Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ordinary differentiation equations (ODE) have proven to be powerful for reconstructing precise and informative gene regulatory networks (GRNs) from dynamic gene expression data. However, joint modeling and analysis of all genes, essential for the systematical characterization of genetic interactions, are challenging due to high dimensionality and a complex pattern of genetic regulation including activation, repression, and antitermination. Here, we address these challenges by unifying variable selection and game theory through ODE. Each gene within a GRN is co-expressed with its partner genes in a way like a game of multiple players, each of which tends to choose an optimal strategy to maximize its “fitness” across the whole network. Based on this unifying theory, we designed and conducted a real experiment to infer salt tolerance-related GRNs for Euphrates poplar, a hero tree that can grow in the saline desert. The pattern and magnitude of interactions between several hub genes within these GRNs were found to determine the capacity of Euphrates poplar to resist to saline stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gene%20regulatory%20network" title="gene regulatory network">gene regulatory network</a>, <a href="https://publications.waset.org/abstracts/search?q=ordinary%20differential%20equation" title=" ordinary differential equation"> ordinary differential equation</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=LASSO" title=" LASSO"> LASSO</a>, <a href="https://publications.waset.org/abstracts/search?q=saline%20resistance" title=" saline resistance"> saline resistance</a> </p> <a href="https://publications.waset.org/abstracts/65286/ordinary-differentiation-equations-ode-reconstruction-of-high-dimensional-genetic-networks-through-game-theory-with-application-to-dissecting-tree-salt-tolerance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">639</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9230</span> Yield, Biochemical Responses and Evaluation of Drought Tolerance of Two Barley Accessions 'Ardhaoui' under Deficit Drip Irrigation Using Saline Water in Southern Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Bagues">Mohamed Bagues</a>, <a href="https://publications.waset.org/abstracts/search?q=Ikbel%20Souli"> Ikbel Souli</a>, <a href="https://publications.waset.org/abstracts/search?q=Feiza%20Boussora"> Feiza Boussora</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Nagaz"> Kamel Nagaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In southern Tunisia, two local barley accessions CV. Ardhaoui; 'Bengardeni' and 'Karkeni' were cultivated in the field under deficit drip irrigation with saline water. Three treatments were used: control or full irrigation T0 (100%ETc) and stressed T1 (75%ETc), T2 (50%ETc). Proline and soluble sugars contents increase significantly under drought between accessions compared to control and varies between growth stages. Moreover, the increasing of Ca2+ concentration enhances the absorption of Na+ ion, consequently K+/Na+ decrease significantly between accessions, these results suggest that a high tolerance of Bengardeni accession to drought stress. Therefore, drought tolerance indices (STI, SSI, MP, GMP, YSI and TOL) were used to identify high yielding and drought tolerant between accessions. MP explained the variation of GYi. GMP and STI explained the variation of GYs. The high values of MP, STI and GMP were associated with higher yielding accession. Higher TOL value is associated with significant grain yield reduction in stressed environment suggesting higher stress responses of accessions. Significant positive correlations between MP, STI and GMP and negative between YSI and SSI. MP, STI, GMP and YSI, TOL, SSI are not correlated with each other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought" title="drought">drought</a>, <a href="https://publications.waset.org/abstracts/search?q=proline" title=" proline"> proline</a>, <a href="https://publications.waset.org/abstracts/search?q=soluble%20sugars" title=" soluble sugars"> soluble sugars</a>, <a href="https://publications.waset.org/abstracts/search?q=minerals" title=" minerals"> minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=drought%20tolerance%20indices" title=" drought tolerance indices"> drought tolerance indices</a>, <a href="https://publications.waset.org/abstracts/search?q=barley" title=" barley"> barley</a> </p> <a href="https://publications.waset.org/abstracts/53059/yield-biochemical-responses-and-evaluation-of-drought-tolerance-of-two-barley-accessions-ardhaoui-under-deficit-drip-irrigation-using-saline-water-in-southern-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53059.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">242</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9229</span> Potential Growth of Tomato Plants in Induced Saline Soil with Rhizobacteria (PGPR)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arfan%20Ali">Arfan Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Idrees%20Ahmad%20Nasir"> Idrees Ahmad Nasir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The critical evaluation of tolerance in tomato plants against the induced saline soil were assessed by transcript analysis of genes coding for products potentially involved in stress tolerance. A reverse transcriptase PCR experiment was performed with Hsp90-1, MT2, and GR1like protein genes using RNA isolated from different tissues of tomato plants. Four strains of Bacillus magisterium were inoculated with 100 Mm & 200 Mm concentrations of salt. Eleven treatments each ten replica pots were installed in green house experiment and the parameters taken into account were morphological (length, weight, number of leaves, leaf surface area), chemical (anthocyanin, chlorophyll-a, chlorophyll-b, carotenoids) and biological (gene expression). Results bare a response i.e. highest response of MT2 like gene was at 24 hpi and the highest levels of GR1 like protein transcript accumulation were detected at 36 hpi. The chemical and morphological parameters at diverse salt concentrations bequeath superlative response amongst strains which candidly flank on Zm7 and Zm4. Therefore, Bacillus magisterium Zm7 strains and somehow Zm4 strain can be used in saline condition to make plants tolerant. The overall performance of strains Zm7, Zm6, and Zm4 was found better for all studied traits under salt stress conditions. Significant correlations among traits root length, shoot length, number of leaves, leaf surface area, carotenoids, anthocyanin, chlorophyll-a and chlorophyll-b were found and suggested that the salt tolerance in tomato may be improved through the use of PGPR strains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20magisterium" title="Bacillus magisterium">Bacillus magisterium</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression%20glutathione%20reductase" title=" gene expression glutathione reductase"> gene expression glutathione reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=metallothionein" title=" metallothionein"> metallothionein</a>, <a href="https://publications.waset.org/abstracts/search?q=PGPR" title=" PGPR"> PGPR</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhizobacteria" title=" Rhizobacteria"> Rhizobacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=saline" title=" saline "> saline </a> </p> <a href="https://publications.waset.org/abstracts/25192/potential-growth-of-tomato-plants-in-induced-saline-soil-with-rhizobacteria-pgpr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25192.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9228</span> Prevalence of Enterocytozoon hepatopenaei in Shrimp Cultured in Inland Saline Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naveen%20Kumar%20B.%20T.">Naveen Kumar B.

For profitable and sustainable aquaculture practices, scientific farming, biosecurity measure, and best fish health management should be the integral part of developmental activities. Keeping in line with global awareness and trends, the Indian government has taken an innovative step to conduct disease surveillance and awareness programme for aquatic disease through network project. This ‘National Surveillance Programme for Aquatic Animal Diseases (NSPAAD)’ is being implemented in collaboration of national institutes and state agriculture universities with funding support from National Fisheries Development Board (NFDB), Govt. of India. Guru Angad Dev Veterinary and Animal Sciences University (GADVASU), Ludhiana, an NSPAAD collaborator, has been actively engaged in disease surveillance in the Indian state of Punjab. Shrimp farming in inland saline areas of Punjab is expanding at a tremendous pace under the guidance of GADVASU along with the support of State Fisheries Department. Under this national disease surveillance programme, we reported Enterocytozoon hepatopenaei (EHP) infection in the Litopenaeus vannamei cultured in the inland saline waters. Polymerase chain reaction (PCR) based diagnosis was carried out using the OIE (World Organisation for Animal Health) protocol. It was observed that out of 20 shrimp farms, two farms were 1st step PCR positive and two more farms were nested PCR positive. All the EHP positive ponds had shown the white faeces along with mortalities at very low rate. Therefore, implementation of biosecurity and continuous surveillance and monitoring program for finfish and shellfish aquaculture are in need of the hour to prevent and control the large-scale disease outbreaks and subsequent economic losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disease" title="disease">disease</a>, <a href="https://publications.waset.org/abstracts/search?q=EHP" title=" EHP"> EHP</a>, <a href="https://publications.waset.org/abstracts/search?q=inland%20saline%20water" title=" inland saline water"> inland saline water</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp%20culture" title=" shrimp culture"> shrimp culture</a> </p> <a href="https://publications.waset.org/abstracts/99684/prevalence-of-enterocytozoon-hepatopenaei-in-shrimp-cultured-in-inland-saline-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99684.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9227</span> The Study of Platelet-Rich Plasma(PRP) on Wounds of OLEFT Rats Using Expression of MMP-2, MMP-9 mRNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ho%20Seong%20Shin">Ho Seong Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: A research in relation to wound healing also showed that platelet-rich plasma (PRP) was effective on normal tissue regeneration. Nonetheless, there is no evidence that when platelet-rich plasma was applied on diabetic wound, it normalize diabetic wound healing process. In this study, we have analyzed matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) expression to know the effect of PRP on diabetic wounds using Reverse transcription-polymerase chain reaction (RT-PCR) of MMP-2, MMP-9 mRNA. Materials and Methods: Platelet-rich plasma (PRP) was prepared from blood of 6 rats. The whole 120-mL was added immediately to an anticoagulant. Citrate phosphonate dextrose(CPD) buffer (0.15 mg CPDmL) in a ratio of 1 mL of CPD buffer to 5 mL of blood. The blood was then centrifuged at 220g for 20minutes. The supernatant was saved to produce fibrin glue. The participate containing PRP was used for second centrifugation at 480g for 20 minutes. The pellet from the second centrifugation was saved and diluted with supernatant until the platelet concentration became 900,000/μL. Twenty male, 4week-old OLETF rats were underwent operation; each rat had two wounds created on left and right sides. The each wound of left side was treated with PRP gel, the wound of right side was treated with physiologic saline gauze. Results: RT-PCR analysis; The levels of MMP-2 mRNA in PRP applied tissues were positively related to postwounding days, whereas MMP-2 mRNA expression in saline-applied tissues remained in 5day after treatment. MMP-9 mRNA was undetectable in saline-applied tissues for either tissue, except 3day after treatment. Following PRP-applied tissues, MMP-9 mRNA expression was detected, with maximal expression being seen at third day. The levels of MMP-9 mRNA in PRP applied tissues were reported high intensity of optical density related to saline applied tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP-2" title=" MMP-2"> MMP-2</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP-9" title=" MMP-9"> MMP-9</a>, <a href="https://publications.waset.org/abstracts/search?q=OLETF" title=" OLETF"> OLETF</a>, <a href="https://publications.waset.org/abstracts/search?q=PRP" title=" PRP"> PRP</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing%0D%0AMMP-9" title=" wound healing MMP-9"> wound healing MMP-9</a> </p> <a href="https://publications.waset.org/abstracts/39065/the-study-of-platelet-rich-plasmaprp-on-wounds-of-oleft-rats-using-expression-of-mmp-2-mmp-9-mrna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39065.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9226</span> A Comparison Study of Different Methods Used in the Detection of Giardia lamblia on Fecal Specimen of Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Farooq%20Baig">Muhammad Farooq Baig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The purpose of this study was to compare results obtained using a single fecal specimen for O&P examination, direct immunofluorescence assay (DFA), and two conventional staining methods.
