Amer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Butanol is an important industrial solvent and potentially a better liquid transportation biofuel than ethanol. The cost of feedstock is one key problem associated with the biobutanol production. Date palm is sugar-rich fruit and highly abundant. Thousands of tons of date wastes that generated from date processing industries are thrown away each year and imposing serious environmental problems. To exploit the utilization of renewable biomass feedstock, date palm waste was utilized for butanol production by Clostridium acetobutylicum DSM 1731. Fermentation conditions were optimized by investigating several parameters that affect the production of butanol such as temperature, substrate concentration and pH. The highest butanol yield (1.0 g/L) and acetone, butanol, and ethanol (ABE) content (1.3 g/L) were achieved at 20 g/L date waste, pH 5.0 and 37 °C. These results suggest that date palm waste can be used for biobutanol production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofuel" title="biofuel">biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=acetone-butanol-ethanol%20fermentation" title=" acetone-butanol-ethanol fermentation"> acetone-butanol-ethanol fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20waste" title=" date palm waste"> date palm waste</a>, <a href="https://publications.waset.org/abstracts/search?q=Clostridium%20acetobutylicum" title=" Clostridium acetobutylicum"> Clostridium acetobutylicum</a> </p> <a href="https://publications.waset.org/abstracts/55719/biobutanol-production-from-date-palm-waste-by-clostridium-acetobutylicum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55719.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">353</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">1389</span> Date Palm Compreg: A High Quality Bio-Composite of Date Palm Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Soltani">Mojtaba Soltani</a>, <a href="https://publications.waset.org/abstracts/search?q=Edi%20Suhaimi%20Bakar"> Edi Suhaimi Bakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Reza%20Naji"> Hamid Reza Naji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Date Palm Wood (D.P.W) specimens were impregnated with Phenol formaldehyde (PF) resin at 15% level, using vacuum/pressure method.

A study was carried out to evaluate the physical characteristics of chopped date palm stalks (fronds and leaflets). These properties are necessary to apply normal design procedures such as pneumatic conveying, fluidization, drying, and combustion. The mechanical treatment by cutting, crushing or chopping and briquetting processes are the primary step and the suitable solution for solving this problem and recycling these residuals to be transformed into useful products. So the aim of the present work to get a high quality for agriculture residues such as date palm stalks (fronds), date palm leaflets briquettes. The results obtained from measuring the mechanical properties (average shear and compressive strength) for date palm stalks at different moisture content (12.63, 33.21 and 60.54%) was (6.4, 4.7 and 3.21MPa) and (3.8, 3.18 and 2.86MPa) respectively. The modulus of elasticity and toughness were evaluated as a function of moisture content. As the moisture content of the stalk regions increased the modulus of elasticity and toughness decreased indicating a reduction in the brittleness of the stalk regions. Chopped date palm stalks (palm fronds), date palm leaflets having moisture content of 8, 10 and 12% and 8, 10 and 12.8% w.b. were dandified into briquettes without binder and with binder (urea-formaldehyde) using a screw press machine. Quality properties for briquettes were durability, compression ratio hardness, bulk density, compression ratio, resiliency, water resistance and gases emission. The optimum quality properties found for briquettes at 8 % moisture content and without binder. Where the highest compression stress and durability were 8.95, 10.39 MPa and 97.06 %, 93.64 % for date palm stalks (palm fronds), date palm leaflets briquettes, respectively. The CO and CO2 emissions for date palm stalks (fronds), date palm leaflets briquettes were less than these for loose residuals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residues" title="residues">residues</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20stalks" title=" date palm stalks"> date palm stalks</a>, <a href="https://publications.waset.org/abstracts/search?q=chopper" title=" chopper"> chopper</a>, <a href="https://publications.waset.org/abstracts/search?q=briquetting" title=" briquetting"> briquetting</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20properties" title=" quality properties"> quality properties</a> </p> <a href="https://publications.waset.org/abstracts/3627/engineering-study-on-the-handling-of-date-palm-fronds-to-reduce-waste-and-used-as-energy-environmentally-friendly-fuel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3627.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">550</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">1386</span> Selection of Endophytcs Fungi Isolated from Date Palm, Halotolerants and Productors of Secondary Metabolite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadila%20Mohamed%20Mahmoud.">Fadila Mohamed Mahmoud.</a>, <a href="https://publications.waset.org/abstracts/search?q=Derkaoui%20I."> Derkaoui I.</a>, <a href="https://publications.waset.org/abstracts/search?q=Krimi%20Z."> Krimi Z. </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Date palm is a plant which presents a very good adaptation to the difficult conditions of the environment in particular to the drought and saline stress even at high temperatures.

Fifteen endophytics fungi isolated from date palm were tested in vitro in the presence of various NaCl concentrations to select halotolerantes isolates. These same endophytes were tested for their colonizing capacity by the description of the production of secondary metabolites more particularly the enzymes (pectinases, proteases, and phosphorylases), and the production of antibiotics and growth hormones.

In the United Arab Emirates, the date palm tree is the most economically important tree which is used for date production as well as an ornamental tree. In 2002, the number of date palm trees in UAE was 40,700,000 and it is increasing over time. The longhorn stem borer (Jebusaea hammerschmidtii) and the lesser date month (Batrachedra amydraula) are important insect pests causing damage to date palm trees in UAE. Population dynamics of the Jebusaea hammerschmidtii and Batrachedra amydraula were studied by using light and pheromons traps, respectively in Al-Ain, UAE. The first trap catch of B. amydraula adults occurred on 19 April and the insect population peaked up on 26 April 2014. The first trap catch of J. hammerschmidtii occurred in April 2014. The numbers increased over time and the population peak occurred in June. The trapping was also done in 2015. The changes in insect numbers in relation to weather parameters are discussed.

In this study, the effect of anti inflammatory of seed and fruit of date palm hydroalcolic extracts, due to having antioxidants, was studied. Materials and Methods: In this study, the extraxts of date palm seed and fruit were prepared by the maceration method in 70% alcohol. Eighty male rats Wistar, divided into 10 groups of eight in each, 4 groups received different doses (100, 200, 400, and 600 mg/kg) of seed extract, and 4 other groups different doses (100, 200, 400, and 600 mg/kg) of fruits extract of the palm, and the positive control aspirin (300mg/kg) and the negative control group saline (5ml/kg) via injection intraperitoneally. Half an hour later, all animals received 100 µl of 1% carrageenan into the rats hind paw subcutaneous. The changes in rats paw edema was measured by plethysmometer every hour for five hours. Results: The effect of all of the doses of date palm seed extract on edema were less than aspirine (P<0.05). But there was no significant difference between the group that received 400 and 600 mg/kg of date palm fruit extract when compared with the aspirin group. The Dose 400 mg/kg of fruit extract showed the most anti-inflammatory effect, and it was assignded as the best dose. Conclusion: It is likely that with further studies on different model of animals and also on the human model, the palm fruit extract could be used for pain treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm" title="palm">palm</a>, <a href="https://publications.waset.org/abstracts/search?q=inflamentory" title=" inflamentory"> inflamentory</a>, <a href="https://publications.waset.org/abstracts/search?q=date" title=" date"> date</a>, <a href="https://publications.waset.org/abstracts/search?q=aspirin" title=" aspirin"> aspirin</a>, <a href="https://publications.waset.org/abstracts/search?q=karageenan" title=" karageenan"> karageenan</a> </p> <a href="https://publications.waset.org/abstracts/155356/the-preventive-effect-of-date-palm-phoenixdactylifera-seed-and-fruit-hydroalcoholic-extracts-on-carrageenan-induced-inflammation-in-male-rats-hind-paw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155356.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">122</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">1383</span> Significance of Water Saving through Subsurface Drip Irrigation for Date Palm Trees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20I.%20Al-Amoud">Ahmed I.

In the first laboratory study, eight subsurface drip irrigation lines available locally, were selected and a number of experiments were made to evaluate line hydraulic characteristics to insure it's suitability for drip irrigation design requirements and high performance to select the best for field experiments. The second study involves field trials on mature date palm trees to study the effect of subsurface drip irrigation system on the yield and water consumption of date palms, and to compare that with the traditional surface drip irrigation system. Experiments were conducted in Alwatania Agricultural Project, on 50 mature palm trees (17 years old) of Helwa type with 10 meters spacing between rows and between trees. A high efficiency subsurface line (Techline) was used based on the results of the first study. Irrigation scheduling was made through a soil moisture sensing device to ensure enough soil water levels in the soil. Experiment layouts were installed during 2001 season, measurements continued till end of 2008 season. Results have indicated that there is an increase in the yield and a considerable saving in water compared to the conventional drip irrigation method. In addition there were high increases in water use efficiency using the subsurface system. The subsurface system proves to be durable and highly efficient for irrigating date palm trees. <p class="card-text"><strong>Keywords:</strong> <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=subsurface%20drip%20irrigation" title=" subsurface drip irrigation"> subsurface drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20trees" title=" date palm trees"> date palm trees</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20water%20use" title=" date palm water use"> date palm water use</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20yield" title=" date palm yield"> date palm yield</a> </p> <a href="https://publications.waset.org/abstracts/1984/significance-of-water-saving-through-subsurface-drip-irrigation-for-date-palm-trees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1984.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">432</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">1382</span> Composite Base Natural Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Mahmoudi">Noureddine Mahmoudi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of natural fibers in the development of composite materials is a sector in full expansion. These fibers were used for their low cost, their availability and their renewable character. The fibers of the palm (palm tree) were used as reinforcement in polypropylene (PP). The date palm fibers have some potential because of their ecological and economic interest. Both unmodified and compatibilized fibers are used. Compatibilization was carried out with the use of maleic anhydride copolymers. The morphology and mechanical properties were characterized by electron microscopy scanning (SEM) and tensile tests. The influence of fiber content on mechanical properties of composite PP / date palm has been evaluated and demonstrated, that the maximum stress and elongation decreases with increasing fiber volume rate. On the other hand, an increase of the tensile modulus has been noticed, but after the fibers improvement, the maximum stress increases significantly up to 25% weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plant%20fiber" title="plant fiber">plant fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=palm" title=" palm"> palm</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibilizer" title=" compatibilizer"> compatibilizer</a> </p> <a href="https://publications.waset.org/abstracts/28197/composite-base-natural-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28197.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">459</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">1381</span> Durability of Lightweight Concrete Material Made from Date Palma Seeds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Almograbi">Mohammed Almograbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Libya is one of the largest producers of dates from date palm, generating about 60000 tonnes of date palm seeds (DPS) annually. This large amount of seeds led to studies into the possible use as aggregates in lightweight concrete for some special structures. The utilization of DPS as aggregate in concrete provides a good solution as alternative aggregate to the stone aggregate. It has been recognized that, DPS can be used as coarse aggregate in structural lightweight concrete industry. For any structure member, the durability is one of the most important considerations during its service life. This paper presents the durability properties of DPS concrete. These include the water permeability, water absorption, sorptivity and chloride penetration.

As three out of four life stages of weevils are concealed inside the host plants, leaving only the adult stage for controlling it. The use of sex pheromone (Ferrugineol) for the management of red palm weevil is considered as the most rewarding technique of IPM. The current studies were conducted to find the relative potential of four different treatments including Sex pheromone, sex pheromone + date fruit + sugarcane pieces, sex pheromone + ethyl acetate and sex pheromone + jaggary water applied on the attraction behavior of weevils. The treatments were applied randomly at two different locations of Dera Ismail Khan, Khyber Pakhtunkhwa, Pakistan including Germ Plasm Unit (GPU) and fruit nursery farm having date palm plants of different ages of four varieties of date palm. The treatments were applied for three consecutive months, including February, March, and April 2022. The pheromone traps were installed at the height of two feet under shade on the western side of date palm plants. The results revealed that among the treatments, T4 consisting of Jaggary water and sex pheromone was found as the most effective treatment and attracted the maximum number of 127 weevils followed by T3 consisting of ethyl acetate and sex pheromone, attracting 53 weevils. In contrast to this, T2 consisting of sex pheromone and date fruit was found as the least effective treatment in attracting red palm weevil and attracted only 15 adult weevils. Among the two selected locations, the population of red palm weevil was found comparatively higher at GPU compared to the nursery farm, Dera Ismail Khan. In conclusion, T4 may be used for the effective and safer management of red palm weevil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=red%20palm%20weevil" title="red palm weevil">red palm weevil</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20management" title=" integrated management"> integrated management</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20pheromones" title=" sex pheromones"> sex pheromones</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaggary%20water" title=" Jaggary water"> Jaggary water</a> </p> <a href="https://publications.waset.org/abstracts/150849/advances-in-the-environmentally-friendly-management-of-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-curculionidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150849.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">101</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">1379</span> Modification of Date Palm Leaflets Fibers Used as Thermoplastic Reinforcement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Almi">K.

Whenever the reinforcements have more thermal stability, they can resist to the main processes for wood–thermoplastic composites. This paper is an investigation of effect of different treatment process on the mechanical proprieties and on the thermal stability of date palm leaflets fibers with a view to improve the date palm fiber proprieties used as reinforcement of thermoplastic materials which main processes require extrusion, hot press. To compare the effect of alkali and acid treatment on the date palm leaflets fiber properties, different treatment were used such as Sodium hydroxide NaOH solution, aluminium chloride AlCl3 and acid treatment with HCL solution. All treatments were performed at 70°C for 4h and 48 h. The mechanical performance (tensile strength and elongation) is affected by immersion time in alkaline and acid solutions. The reduction of the tensile strength and elongation of fibers at 48h was higher in acid treatment than in alkali treatment at high concentration. No significant differences were observed in mechanical and thermal proprieties of raw fibers and fibers submerged in AlCl3 at low concentration 1% for 48h. Fibers treated by NaOH at 6% for 4h showed significant increase in the mechanical proprieties and thermal stability of date palm leaflets fibers. Hence, soda treatment is necessary to improve the fibers proprieties and consequently optimize the composite performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20fibers" title="date palm fibers">date palm fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20treatments" title=" surface treatments"> surface treatments</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoplastic%20composites" title=" thermoplastic composites"> thermoplastic composites</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a> </p> <a href="https://publications.waset.org/abstracts/15299/modification-of-date-palm-leaflets-fibers-used-as-thermoplastic-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15299.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">342</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">1378</span> Karyotyping the Date Palm (Phoenix dactylifera L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20M.%20Alzahrani">Abdullah M.

Data showed no variation in chromosome number, 2n = 36, 34 autosomes in addition to XX in females and XY in males. Mean autosomes length ranged from 3.85-9.93 μm and 3.71-2.73 μm for X and Y chromosomes, respectively. The formula of female date palm karyotype was 8m + 4sm +2st + 4t, and submedian Y chromosome. Relative chromosome length ranged from 3.3- 9.38 μm. SS cultivar showed high asymmetry levels by scoring low values of Syi (45.51), TF (42.8) and high values for A1 (0.53), A (0.41) and AI (0.29). Syi developed an inverse relation with A1 and A while A exhibited a direct correlation with A1. Cultivars SK, SB and SJ score medium values of Syi, A1, AI and A. KH cultivar exhibited high symmetry by scoring highest values of Syi (53.68), TF (51.81) and lowest values of A1 (0.44), A (0.34) and AI (0.18). Higher DI value was obtained in SB cultivar (1.34) followed by SJ (1.15) and low DI scores of 0.99, 0.86 and 0.71 were detected in KH, SS and SK, respectively. Stebbins classification assorted SS as 3B and the other cultivars as 2B, insuring the evolution and asymmetry of SS compared to the other karyotypes. Scatter diagram of Syi-A1 couple has the advantage of revealing high degree of sensitivity to present karyotype interrelationships, followed by AI-A and CVCL-CVCI couples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karyotype" title="Karyotype">Karyotype</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm" title=" date palm"> date palm</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalas" title=" Khalas"> Khalas</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukkary" title=" Sukkary"> Sukkary</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheeshi" title=" Sheeshi"> Sheeshi</a> </p> <a href="https://publications.waset.org/abstracts/40557/karyotyping-the-date-palm-phoenix-dactylifera-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40557.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">369</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">1377</span> Safety Date Fruits for Human Being as Affected by Nitrogen Fertilization Applications in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Attalla">A.

The palms received recommended dose of mineral N only or plus different rates of organic N with or without bio fertilizer to study the effect of such treatments on date palm yield and fruit nitrate and nitrite content due to its negative influence on human, animal and environment. The obtained results clarified that all used treatments of organic and bio fertilizers were effective in improving date palm yield and decreased fruit content of NO2 and NO3 in comparison with 100 % mineral N. It was also noticed that combined treatments of 50 % mineral N + 50 % organic manure with bio fertilizer is the superior treatments for increasing the values of yield and decreasing its content of NO2 and NO3. Hence, it could be concluded that, minimizing the use of chemical nitrogen fertilizer to half of recommended dose through addition of 50 % mineral N + 50 % organic manure with bio fertilizer and also, the utilization of organic and bio fertilizers is considered as a promising alternative for chemical fertilizers to avoid pollution and reduce the costs of mineral fertilizers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20and%20bio%20fertilizers" title="organic and bio fertilizers">organic and bio fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20fertilizer" title=" mineral fertilizer"> mineral fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrite" title=" nitrite"> nitrite</a>, <a href="https://publications.waset.org/abstracts/search?q=zaghloul%20date%20palm%20cv" title=" zaghloul date palm cv"> zaghloul date palm cv</a> </p> <a href="https://publications.waset.org/abstracts/35352/safety-date-fruits-for-human-being-as-affected-by-nitrogen-fertilization-applications-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35352.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">449</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">1376</span> Thermal Proprieties of Date Palm Wood </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Almi">K.

This paper reports the results of an experimental investigation on the thermal proprieties of date palm wood from Algeria. A study of physical, chemical, and mechanical properties is also carried out. The goal is to use this natural material in the manufacture of thermal insulation materials for buildings. The local natural resources used in this study are the date palm fibers from Biskra oasis in Algeria. The results have shown that there is no significant difference in the morphological proprieties of the four types of residues. Their chemical composition differed slightly; with the lowest amounts of cellulose and lignin content belong to Petiole. Water absorption study proved that Rachis has a low value of sorption whereas Petiole and Fibrillium have a high value of sorption what influenced their mechanical properties. It is seen that the Rachis and leaflets exhibit high tensile strength values compared to the other residue. On the other hand, the low value of the bulk density of Petiole and Fibrillium leads to a high value of specific tensile strength and young modulus. It was found that the specific young modulus of Petiole and Fibrillium was higher than that of Rachis and Leaflets and that of other natural fibers or even artificial fibers. Compared to the other materials date palm wood provide a good thermal proprieties thus, date palm wood will be a good candidate for the manufacturing efficient and safe insulating materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20fiber" title=" date palm fiber"> date palm fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fibers" title=" natural fibers"> natural fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20tests" title=" tensile tests"> tensile tests</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20proprieties" title=" thermal proprieties"> thermal proprieties</a> </p> <a href="https://publications.waset.org/abstracts/14539/thermal-proprieties-of-date-palm-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14539.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">293</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">1375</span> Influence of Partially-Replaced Coarse Aggregates with Date Palm Seeds on the Concrete Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahed%20Alrshoudi">Fahed Alrshoudi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Saudi Arabia is ranked the third of the largest suppliers of Dates worldwide (about 28.5 million palm trees), producing more than 2 million tons of dates yearly.

The date seeds are stiff, therefore, it is possible to utilize DPS as coarse aggregates in lightweight concrete for certain structural applications and to participate at reusing the waste. The use of DPS as coarse aggregate in concrete can be an alternative choice as a partial replacement of the stone aggregates (SA).

The date palm is an economically important crop in Libya and contributes to the agriculture industry, foreign exchange earnings, farmers’ income, and employment in the country. The date palm industry relies on large amounts of water for growing the crop. Farmers in Southwest Libya use a variety of irrigation systems, but the quality and quantity of water varies between systems and this affects the productivity and income of farmers. Using survey data from 210 farmers, this study estimated and assessed the pros and cons of different types of irrigation systems for date palm production under various irrigation systems currently used in Sebha, Libya. The number of years farmers have used irrigation, the area, irrigation water consumption, time of irrigation, number of farm workers (including family labour) and inputs used were measured for surface, sprinkler and drip irrigation methods. Findings from this research provide new insights into the advantages and disadvantages of the various irrigation systems, problems encountered by farmers and the factors that affect the quality and quantity of the irrigation system. The paper discussed proposed solutions to deal with the problems including timing of irrigation, canal maintenance, repair of wells and water control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Libya" title="Libya">Libya</a>, <a href="https://publications.waset.org/abstracts/search?q=factors" title=" factors"> factors</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20method" title=" irrigation method"> irrigation method</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm" title=" date palm"> date palm</a> </p> <a href="https://publications.waset.org/abstracts/33653/pros-and-cons-of-different-types-of-irrigation-systems-for-date-palm-production-in-sebha-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33653.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">351</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">1373</span> Manufacturing New Insulating Materials: A Study on Thermal Properties of Date Palm Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Almi">K.

Water absorption study proved that Rachis has a low value of sorption whereas Petiole and Fibrillium have a high value of sorption what influenced their mechanical properties. It is seen that the Rachis and leaflets exhibit a high tensile strength values compared to the other residue. On the other hand the low value of bulk density of Petiole and Fibrillium leads to high value of specific tensile strength and young modulus. It was found that the specific young modulus of Petiole and Fibrillium was higher than that of Rachis and Leaflets and that of other natural fibers or even artificial fibers. Compared to the other materials date palm wood provide a good thermal proprieties thus, date palm wood will be a good candidate for the manufacturing efficient and safe insulating materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title="composite materials">composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20fiber" title=" date palm fiber"> date palm fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fibers" title=" natural fibers"> natural fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20tests" title=" tensile tests"> tensile tests</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20proprieties" title=" thermal proprieties"> thermal proprieties</a> </p> <a href="https://publications.waset.org/abstracts/14220/manufacturing-new-insulating-materials-a-study-on-thermal-properties-of-date-palm-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14220.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">642</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">1372</span> Landscape Genetic and Species Distribution Modeling of Date Palm (Phoenix dactylifera L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Sheidaei">Masoud Sheidaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahimeh%20Koohdar"> Fahimeh Koohdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Date palms are economically important tree plants with high nutrition and medicinal values. More than 400 date palm cultivars are cultivated in many regions of Iran, but no report is available on landscape genetics and species distribution modeling of these trees from the country. Therefore, the present study provides a detailed insight into the genetic diversity and structure of date palm populations in Iran and investigates the effects of geographical and climatic variables on the structuring of genetic diversity in them. We used different computational methods in the study like, spatial principal components analysis (sPCA), redundancy analysis (RDA), latent factor mixed model (LFMM), and Maxent and Dismo models of species distribution modeling. We used a combination of different molecular markers for this study. The results showed that both global and local spatial features play an important role in the genetic structuring of date palms, and the genetic regions associated with local adaptation and climatic variables were identified. The effects of climatic change on the distribution of these taxa and the genetic regions adaptive to these changes will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20genetic%20regions" title="adaptive genetic regions">adaptive genetic regions</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation%20by%20distance" title=" isolation by distance"> isolation by distance</a>, <a href="https://publications.waset.org/abstracts/search?q=populations%20divergence" title=" populations divergence"> populations divergence</a> </p> <a href="https://publications.waset.org/abstracts/166909/landscape-genetic-and-species-distribution-modeling-of-date-palm-phoenix-dactylifera-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166909.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">109</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">1371</span> Removal of Organics Pollutants from Wastewater by Activated Carbon Prepared from Dates Stones of Southern Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abasse%20Kamarchou">Abasse Kamarchou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdelhafid%20Bebba"> Ahmed Abdelhafid Bebba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Douadi"> Ali Douadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is the preparation of an activated carbon from waste date palm from El Oued region, namely the date stones and its use in the treatment of wastewater in this region.

In this study, an activated carbon was prepared from palm trunks by chemical processes. The chemical activation was performed by impregnation of the raw materials after grinding with H3PO4 solution (63%), followed by placing of the sample solution on a muffle furnace at 400ºC for 30 min, and then at 800ºC for 10 min. The morphology of the fabricated material was checked using scanning electron microscopy that showed the rough surfaces on the carbon samples. The use of fabricated activated carbon for removal of eosin dye from aqueous solutions at different contact time, initial dye concentration, pH and adsorbent doses was investigated. The experimental results show that the adsorption process attains equilibrium within 20 min. The adsorption isotherm equilibrium was studied by means of the Langmuir and Freundlich isotherms, and it was found that the data fit the Langmuir isotherm equation with maximum monolayer adsorption capacity of 126.58 mg g-1.

The use of agricultural solid wastes is considered as low-cost and eco-friendly adsorbents for removing dyes from waste water. Date palm fibre, an abundant agricultural by-product in Egypt was used to prepare activated carbon by physical activation method. This study investigates the use of date palm fiber (DPF) and activated carbon (DPFAC) for the removal of a basic dye, methylene blue (MB) from simulated waste water. The effects of temperature, pH of solution, initial dye (concentration, adsorbent dosage and contact time were studied. The experimental equilibrium adsorption data were analyzed by Langmuir, Freundlich, Temkin, Dubinin, Radushkevich and Harkins–Jura isotherms. Adsorption kinetics data were modeled using the pseudo-first and pseudo-second order and Elvoich equations. The mechanism of the adsorption process was determined from the intraparticle diffusion model. The results revealed that as the initial dye concentration , amount of adsorbent and temperature increased, the percentage of dye removal increased. The optimum pH required for maximum removal was found to be 6. The adsorption of methylene blue dye was better described by the pseudo-second-order equation. Results indicated that DPFAC and DPF could be an alternative for more costly adsorbents used for dye removal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=basic%20dye" title=" basic dye"> basic dye</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20fiber" title=" palm fiber"> palm fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon "> activated carbon </a> </p> <a href="https://publications.waset.org/abstracts/29399/adsorption-of-basic-dyes-using-activated-carbon-prepared-from-date-palm-fibre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29399.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">331</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">1368</span> Olfactometer Response of Red Palm Weevil (Rhynchophorus ferrugineus) (Coleoptera: Curculionidae) and Its Biology for the Evaluation of Resistance in the Commercially Grown Date Palm (Phoenix dactylifera L.)

Insect pests' attacks on different palm cultivars adversely affected their production in the last few decades. Pakistan ranked sixth for date production around the world. The most commercially grown cultivars are Aseel, Dhaki, Falsi, Karbalai, Mozawati, Jan Swore, Kohra, Hillawi, Kohra, and Begum Jhangi. Red palm weevils are considered as hazardous insect pests responsible for economic loss in palm orchards. This research work depicts the infestation of red palm weevils in eleven different palm cultivars (Hillawi, Mozawati, Kechanr, Aseel, Shamrani, Khudravi, Dhaki, Zeri, Kobra, Zaidi, Denda), which frequently grow in different regions of Pakistan through Y-shaped olfactometer analysis. In addition, the level of both antixenosis and antibiosis was spotted by examining the various parameters such as %age lure of weevils of mature females, general count of laid eggs in addition to their activeness. Furthermore, obtained results depicted that a positive contact was established with minimum antixenotic consequence revealed by a cultivar, “Hillawi” among most hold of RPW adults (22.32%), number of eggs laid (16.66%) and egg hatching (84.66%), while other cultivars, including Mozawati, Aseel, Kechanr, Shamrani, Khudravi, Dhaki, Zeri, and Zaidi, exhibited a greater level of antixenosis. Moreover, “Hillawi” documented the maximum number of eggs, while Kechanr, Mozawati, Aseel Kobra, and Denda showed minimum attraction by red palm weevils. Maximum red palm weevils were attracted in an olfactometer assay of sugarcane varieties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20dactylifera" title="P. dactylifera">P. dactylifera</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20ferrugineus" title=" R. ferrugineus"> R. ferrugineus</a>, <a href="https://publications.waset.org/abstracts/search?q=olfactometer" title=" olfactometer"> olfactometer</a>, <a href="https://publications.waset.org/abstracts/search?q=antixenosis" title=" antixenosis"> antixenosis</a> </p> <a href="https://publications.waset.org/abstracts/157900/olfactometer-response-of-red-palm-weevil-rhynchophorus-ferrugineus-coleoptera-curculionidae-and-its-biology-for-the-evaluation-of-resistance-in-the-commercially-grown-date-palm-phoenix-dactylifera-l-cultivars-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157900.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">114</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">1367</span> Physical and Rheological Properties of Asphalt Modified with Cellulose Date Palm Fibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Howaidi%20M.%20Al-Otaibi">Howaidi M.

In this study, empty fruit bunch of date palm trees were used to produce cellulose fiber that were used as additives in the asphalt binder. Two sizes (coarse and fine) of cellulose fibers were pre-blended in PG64-22 binder with various contents of 1.5%, 3%, 4.5%, 6%, and 7.5% by weight of asphalt binder. The physical and rheological properties of fiber modified asphalt binders were tested by using conventional tests such as penetration, softening point and viscosity; and SHRP test such as dynamic shear rheometer. The results indicated that the fiber modified asphalt binders were higher in softening point, viscosity, and complex shear modulus, and lower in penetration compared to pure asphalt. The fiber modified binders showed an improvement in rheological properties since it was possible to raise the control binder (pure asphalt) PG from 64 to 70 by adding 6% (by weight) of either fine or coarse fibers.

It plays an important role, not only due to its economic importance, but also its ecological adaptation to, firstly, to ensure necessary protection for crops against underlying warm and dry sales, and secondly to contribute to the fight against desertification. This is one of the oldest cultivated plant species best adapted to difficult climatic conditions of the Saharan and pre-Saharan regions, because of its ecological requirements and economically most suitable for investing in oasis agriculture. Methodology The methodology is mainly based on a literature review of principal theses and projects for the conservation of flora and vegetation. Results The date palm has multiple uses. Indeed, it produces fruits rich in nutrients, provides a multitude of secondary products and generates needed revenue for the survival of oasis populations. In Morocco, the development and modernization of the date palm sector face, both upstream and downstream of the industry, several major constraints. In addition to climate constraints (prolonged drought), in its environment (lack of water resources), to the incessant invasion of disease Bayoud, Moroccan palm ecosystem suffers from a low level of technical and traditional practices prevail and traditional, from the choice of variety and site preparation up to harvesting and recycling of products. Conclusion The date palm plays an important role in the socioeconomic development of local and national level. However, this ecosystem however, is subject to numerous degradation factors caused by anthropogenic action and climate change. to reverse the trends, several programs have been developed by Morocco for the restoration of degraded areas and the development of the Phoenix dactylifera ecosystem to meet the needs of local populations and the development of the national economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efforts" title="efforts">efforts</a>, <a href="https://publications.waset.org/abstracts/search?q=flora" title=" flora"> flora</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=forest" title=" forest"> forest</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/173754/phoenix-dactylifera-ecosystem-in-morocco-ecology-socio-economic-role-and-constraints-to-its-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173754.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">87</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">1364</span> Test of Biological Control against Date Moth Ectomyelois ceratoniae zeller (Lepidoptera, Pyralidae) by Spinosad</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadjeb%20Ayoub">Hadjeb Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehaoua%20Med%20Seghir"> Mehaoua Med Seghir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouakid%20M.%20Laid"> Ouakid M.

In this context we conducted our work to explore the insecticidal activity of Spinpsad which is a bio-pesticide on the larval stages of Ectomyelois ceratoniae. The study of the effect of Spinosad on the mortality of different larval stages revealed that the doses used were significantly and positively correlated with mortality adjusted for different durations of exposure of larvae bio- pesticide. Lowest corrected mortality was observed in a short time and lethal in older larvae treated with the lowest concentration. While the higher mortality was observed in a longer duration of exposure in younger instars treated with the highest concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ectomyelois%20ceratoniae" title="Ectomyelois ceratoniae">Ectomyelois ceratoniae</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm" title=" date palm"> date palm</a>, <a href="https://publications.waset.org/abstracts/search?q=Spinosad" title=" Spinosad"> Spinosad</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title=" biological control"> biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicology" title=" toxicology"> toxicology</a> </p> <a href="https://publications.waset.org/abstracts/16591/test-of-biological-control-against-date-moth-ectomyelois-ceratoniae-zeller-lepidoptera-pyralidae-by-spinosad" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16591.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">432</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">1363</span> Antioxidant Activity and Correlation of Free Phenolic Content with the DPPH Radical Scavenging and Reducing Power Activity of Date Palm (Phoenix dactylifera L.) from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheyma%20Bensaci">Cheyma Bensaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Saidi"> Mokhtar Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ghiaba"> Zineb Ghiaba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The first objective of this study is to determine the phenolic contents and antioxidant capacities of three different varieties of date palm (Phoenix dactylifera L.) fruit (DPF) from Algeria were using three different solvents. As for the second objective is to find the correlation of phenolic contents with the both DPPH radical scavenging and reducing power activity. These results showed that date had strongly scavenging activity on DPPH .The IC50 value for DPPH radical scavenging activity was 0.15 mg/ml in acetone/H2O extract from Gh. And also, acetone/H2O extract from Gh showed the best AEAC value for reducing power was 8,48 mM. The results also showed that there are a positive correlation, so confined values between 0.153 and 0.972. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phoenix%20dactylifera" title="phoenix dactylifera">phoenix dactylifera</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation" title=" correlation"> correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=reducing%20power" title=" reducing power"> reducing power</a> </p> <a href="https://publications.waset.org/abstracts/39122/antioxidant-activity-and-correlation-of-free-phenolic-content-with-the-dpph-radical-scavenging-and-reducing-power-activity-of-date-palm-phoenix-dactylifera-l-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39122.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">380</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">1362</span> Expanding Chance of Palm Oil Market into ASEAN Community: Case Study of Choomporn Palm Oil Cooperative</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pichamon%20Chansuchai">Pichamon Chansuchai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studied the expanding market opportunity palm oil ASEAN community: case study of Choomporn Palm Oil Cooperative as qualitative research. The purpose is to study and analyze expanding and linking the liberalization of trade in palm oil products under the terms of cooperation and ASEAN countries. Collection data were collected using participatory observation, in-depth interviews, focus groups, government officials, palm oil cooperative, entrepreneurs and farmers to exchange opinions. The study found that of major competitors is Indonesia and Malaysia which as ASEAM members countries has the potential to produce over Thailand. Thailand government must have a policy to increase the competitiveness of the palm oil Thailand. Using grants from the Free Trade Area fund should add value to agricultural products, palm oil and the development of standard products to meet the needs of the member countries. And creating a learning center of the palm oil sector can transfer knowledge, development of palm species, solution process from planting to harvest care privatization process. And the development of palm oil in order to expand market opportunities for Thailand's palm oil has the potential to be competitive in the neighboring countries and the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20oil" title="palm oil">palm oil</a>, <a href="https://publications.waset.org/abstracts/search?q=market" title=" market"> market</a>, <a href="https://publications.waset.org/abstracts/search?q=cooperative" title=" cooperative"> cooperative</a>, <a href="https://publications.waset.org/abstracts/search?q=ASEAN" title=" ASEAN"> ASEAN</a> </p> <a href="https://publications.waset.org/abstracts/53212/expanding-chance-of-palm-oil-market-into-asean-community-case-study-of-choomporn-palm-oil-cooperative" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53212.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">500</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">1361</span> Fluorescence Sensing as a Tool to Estimate Palm Oil Quality and Yield</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norul%20Husna%20A.%20Kasim">Norul Husna A.

Ineffective maturity assessment and untimely harvesting have compounded this problem. Typically, the traditional method of palm oil quality and yield assessment is destructive, costly and laborious. Fluorescence-sensing offers a new means of assessing palm oil quality and yield non-destructively. This work describes the estimation of palm oil quality and yield using a multi-parametric fluorescence sensor (Multiplex®) to quantify the concentration of secondary metabolites, such as anthocyanin and flavonoid, in fresh fruit bunches across three different palm ages (6, 9, and 12 years-old). Results show that fluorescence sensing is an effective means of assessing FFB maturity, in terms of palm oil quality and yield quantifications. <p class="card-text"><strong>Keywords:</strong> <a
