As we work with quantum information and computation with continuous variables, Gaussian states are needed to better describe these systems. Analyzing a single ion locked in a Paul trap we use the interaction picture to obtain a toolbox of Gaussian operations with the ion-laser interaction Hamiltionian. This is achieved exciting the ion through the combination of two lasers of distinct frequencies corresponding to different sidebands of the external degrees of freedom. First we study the case of a trap with 1 mode and then the case with 2 modes. In this way, we achieve different continuous variables gates just by changing the external degrees of freedom of the trap and combining the Hamiltonians of blue and red sidebands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paul%20trap" title="Paul trap">Paul trap</a>, <a href="https://publications.waset.org/abstracts/search?q=ion-laser%20interaction" title=" ion-laser interaction"> ion-laser interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20operations" title=" Gaussian operations"> Gaussian operations</a> </p> <a href="https://publications.waset.org/abstracts/18445/gaussian-operations-with-a-single-trapped-ion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18445.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">686</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">635</span> Evaluation of Pheromone and Tree Trap Efficiency in Orthotomicus erosus (Col: Curculionidae: Scolytinae) Monitoring in Pine Forests of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sudabe%20Amini">Sudabe Amini</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamasb%20Nozari"> Jamasb Nozari</a>, <a href="https://publications.waset.org/abstracts/search?q=Somaye%20Rahimi"> Somaye Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bark beetles are one of the most destructive groups of pests in the forest and green space. Mediterranean pine Engraver Orthotomicus erosus (Wollston) is the dominant species in the pine forests of Iran. Pine forests are considered a crucial region in the world and need high protection. Although there is no effective control method, mass trapping is the most common method to suppress the bark beetle population. Due to this, from 2018-to 2020, a survey was conducted on bark beetles mass trapping by using two kinds of traps, including pheromone and tree trap. These traps were evaluated in 10 different sites of pine forests. The statistical results proved that significant differences between the pheromone trap and tree trap were observed. It confirmed that the pheromone trap attracted more beetles than the tree trap. The results of this study suggest that the most effective and applicable method in bark beetle’s management of pines forest is using a pheromone trap that suppresses and maintains bark beetle’s population at an economic level, although tree traps attract bark beetles too. In the future, using tree-pheromone traps, which would synergist attraction of more bark beetles, is recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bark%20beetle" title="bark beetle">bark beetle</a>, <a href="https://publications.waset.org/abstracts/search?q=pines%20forest" title=" pines forest"> pines forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Orthotomicus%20erosus" title=" Orthotomicus erosus"> Orthotomicus erosus</a>, <a href="https://publications.waset.org/abstracts/search?q=pheromone%20trap" title=" pheromone trap"> pheromone trap</a>, <a href="https://publications.waset.org/abstracts/search?q=tree%20trap" title=" tree trap"> tree trap</a> </p> <a href="https://publications.waset.org/abstracts/149156/evaluation-of-pheromone-and-tree-trap-efficiency-in-orthotomicus-erosus-col-curculionidae-scolytinae-monitoring-in-pine-forests-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149156.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">167</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">634</span> Performance of Different Biodegradable Waxes Based Specialized Pheromone and Lure Application Technology-Male Anhelation Technique-Cue Lure Formulations in Bittergourd Field against Bactrocera cucurbitae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amna%20Jalal">Amna Jalal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Dildar%20Gogi"> Muhammad Dildar Gogi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Jalal%20Arif"> Muhammad Jalal Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Anum%20Tariq"> Anum Tariq</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Afzal%20Naveed"> Waleed Afzal Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Talha%20Farooq"> Talha Farooq</a>, <a href="https://publications.waset.org/abstracts/search?q=Mubashir%20Iqbal"> Mubashir Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Junaid%20Nisar"> Muhammad Junaid Nisar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Melon fruit flies (Diptera: Tephritidae: Dacinae) are economically important pests of the cucurbits and are geographically distributed throughout the tropics and subtropics of the world. It causes heavy quantitative and qualitative losses in bitter gourd. The present experiment was carried out to evaluate the performance of different biodegradable waxes based SPLAT-MAT-CL (Specialized Pheromone and Lure Application Technology-Male Anhelation Technique- Cue Lure) formulations in bitter gourd field. Fourteen SPLAT-MAT emulsions/formulations were prepared by admixing different SPLAT matrices with toxicant (spinosad) and sex pheromone cuelure (attractant) in different proportionate percentage by weight. The results revealed that attraction and trapping of fruit flies of B. cucurbitae varied significantly for different SPLAT-MAT-CL formulations (p < 0.05). The maximum B. cucurbitae males were trapped in SPLAT-MAT-CL-7 (60 flies/trap/day) followed by SPLAT-MAT-CL-9 (40 flies/trap/day). The performance of all other formulations of SPLAT-MAT-CL was found in the order of SPLAT-MAT-CL-8 (30 flies/trap/day) > SPLAT-MAT-CL-3 (28 flies/trap/day) > SPLAT-MAT-CL-5 (25 flies/trap/day) > SPLAT-MAT-CL-4 (22 flies/trap/day) > SPLAT-MAT-CL-12 (20 flies/trap/day) SPLAT-MAT-CL-2 (19 flies/trap/day) > SPLAT-MAT-CL-14 (17 flies/trap/day) > SPLAT-MAT-CL-13 (15 flies/trap/day) > SPLAT-MAT-CL-11 (10 flies/trap/day) > SPLAT-MAT-CL-1 (8 flies/trap/day) > SPLAT-MAT-CL-10 (02 flies/trap/day). Overall, all the SPLAT-MAT-CL formulations, except SPLAT-MAT-CL-10, demonstrated higher density of captures of B. cucurbitae males as compared to standard (06 flies/trap/day). The results also demonstrate that SPLAT-MAT-CL-7, SPLAT-MAT-CL-9, SPLAT-MAT-CL-8, SPLAT-MAT-CL-3, SPLAT-MAT-CL-5, SPLAT-MAT-CL-4, SPLAT-MAT-CL-12, SPLAT-MAT-CL-2, SPLAT-MAT-CL-14, SPLAT-MAT-CL-13, SPLAT-MAT-CL-11 and SPLAT-MAT-CL-1 explained approximately 5, 4.6, 4.1, 3.6, 3.3, 3.1,2.8,2.5 and 1.6 times higher captures of B. cucurbitae males over standards. However, SPLAT-MAT-CL-10 demonstrated 3 times fewer captures of B. cucurbitae males over standards. In conclusion, SPLAT-MAT-CL-7, SPLAT-MAT-CL-9 can be exploited for the monitoring and trapping of B. cucurbitae in its IPM of program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attractancy" title="attractancy">attractancy</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20conditions" title=" field conditions"> field conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=melon%20fruit%20fly" title=" melon fruit fly"> melon fruit fly</a>, <a href="https://publications.waset.org/abstracts/search?q=SPLAT-MAT-CL" title=" SPLAT-MAT-CL"> SPLAT-MAT-CL</a> </p> <a href="https://publications.waset.org/abstracts/97310/performance-of-different-biodegradable-waxes-based-specialized-pheromone-and-lure-application-technology-male-anhelation-technique-cue-lure-formulations-in-bittergourd-field-against-bactrocera-cucurbitae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97310.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">633</span> Optimization of Spatial Light Modulator to Generate Aberration Free Optical Traps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepak%20K.%20Gupta">Deepak K.

Ravindran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Holographic Optical Tweezers (HOTs) in general use iterative algorithms such as weighted Gerchberg-Saxton (WGS) to generate multiple traps, which produce traps with 99% uniformity theoretically. But in experiments, it is the phase response of the spatial light modulator (SLM) which ultimately determines the efficiency, uniformity, and quality of the trap spots. In general, SLMs show a nonlinear phase response behavior, and they may even have asymmetric phase modulation depth before and after π. This affects the resolution with which the gray levels are addressed before and after π, leading to a degraded trap performance. We present a method to optimize the SLM for a linear phase response behavior along with a symmetric phase modulation depth around π. Further, we optimize the SLM for its varying phase response over different spatial regions by optimizing the brightness/contrast and gamma of the hologram in different subsections. We show the effect of the optimization on an array of trap spots resulting in improved efficiency and uniformity. We also calculate the spot sharpness metric and trap performance metric and show a tightly focused spot with reduced aberration. The trap performance is compared by calculating the trap stiffness of a trapped particle in a given trap spot before and after aberration correction. The trap stiffness is found to improve by 200% after the optimization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spatial%20light%20modulator" title="spatial light modulator">spatial light modulator</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20trapping" title=" optical trapping"> optical trapping</a>, <a href="https://publications.waset.org/abstracts/search?q=aberration" title=" aberration"> aberration</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20modulation" title=" phase modulation"> phase modulation</a> </p> <a href="https://publications.waset.org/abstracts/106122/optimization-of-spatial-light-modulator-to-generate-aberration-free-optical-traps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106122.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">187</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">632</span> Behavioral and Electroantennographic Responses of the Tea Shot Hole Borer, Euwallacea fornicatus, Eichhoff (Scolytidae: Coleoptera) to Volatiles Compounds of Montanoa bipinnatifida (Compositae: Asteraceae) and Development of a Kairomone Trap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sachin%20Paul%20James">Sachin Paul James</a>, <a href="https://publications.waset.org/abstracts/search?q=Selvasundaram%20Rajagopal"> Selvasundaram Rajagopal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muraleedharan%20Nair"> Muraleedharan Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Babu%20Azariah"> Babu Azariah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shot hole borer (SHB), Euwallacea fornicatus (= Xyleborus fornicatus) (Scolytidae: Coleoptera) is one of the major pests of tea in southern India and Sri Lanka. The partially dried cut stem of a jungle plant, Montanoa bipinnatifida (C.Koch) (Compositae: Asteraceae) reported to attract shot hole borer beetles in the field. Collection, isolation, identification and quantification of the emitted volatiles from the partially dried cut stems of M. bipinnatifida using dynamic head space and GC-MS revealed the presence of seven compounds viz. α- pinene, β- phellandrene, β - pinene, D- limonene, trans-caryophyllene, iso- caryophyllene and germacrene– D. Behavioural bioassays using electroantennogram (EAG) and wind tunnel proved that, among these identified compounds only α - pinene, trans-caryophyllene, β – phellandrene and germacrene-D evoked significant behavioral response and maximum response was obtained to a specific blend of these four compounds @ 10:1:0.1:3. Field trapping experiments of this blend conducted in the SHB infested field using multiple funnel traps further proved the efficiency of the blend with a mean trap catch of 176.7 ± 13.1 beetles. Mass trapping studies in the field helped to develop a kairomone trap for the management of SHB in the tea fields of southern India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroantennogram" title="electroantennogram">electroantennogram</a>, <a href="https://publications.waset.org/abstracts/search?q=kairomone%20trap" title=" kairomone trap"> kairomone trap</a>, <a href="https://publications.waset.org/abstracts/search?q=Montanoa%20bipinnatifida" title=" Montanoa bipinnatifida"> Montanoa bipinnatifida</a>, <a href="https://publications.waset.org/abstracts/search?q=tea%20shot%20hole%20borer" title=" tea shot hole borer"> tea shot hole borer</a> </p> <a href="https://publications.waset.org/abstracts/72827/behavioral-and-electroantennographic-responses-of-the-tea-shot-hole-borer-euwallacea-fornicatus-eichhoff-scolytidae-coleoptera-to-volatiles-compounds-of-montanoa-bipinnatifida-compositae-asteraceae-and-development-of-a-kairomone-trap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72827.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">223</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">631</span> Study the effect of bulk traps on Solar Blind Photodetector Based on an IZTO/β Ga2O3/ITO Schottky Diode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laboratory%20of%20Semiconducting">Laboratory of Semiconducting</a>, <a href="https://publications.waset.org/abstracts/search?q=Metallic%20Materials%20%28LMSM%29%20Biskra%20Algeria">Metallic Materials (LMSM) Biskra Algeria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> InZnSnO2 (IZTO)/β-Ga2O3 Schottky solar barrier photodetector (PhD) exposed to 255 nm was simulated and compared to the measurement. Numerical simulations successfully reproduced the photocurrent at reverse bias and response by taking into account several factors, such as conduction mechanisms and material parameters. By adopting reducing the density of the trap as an improvement. The effect of reducing the bulk trap densities on the photocurrent, response, and time-dependent (continuous conductivity) was studied. As the trap density decreased, the photocurrent increased. The response was 0.04 A/W for the low Ga2O3 trap density. The estimated decay time for the lowest intensity ET (0.74, 1.04 eV) is 0.05 s and is shorter at ∼0.015 s for ET (0.55 eV). This indicates that the shallow traps had the dominant effect (ET = 0.55 eV) on the continuous photoconductivity phenomenon.

Use of chemicals to minimize these problems of insect pests in paddy field can lead to the residue and affect the health of farmers. Therefore, botanical extracts applied for controlling rice serious enemies should be promoted especially use of plant extract as attractants to lure insects. This research aimed to feasibility study of bioattractants from pandanus palm extracts for trapping insect pets using two different trap models, including plastic bottle and yellow sticky traps. Two main growth and development stages of rice, namely tillering and booting stages, were selected and trapped. The results from both trap models revealed that four rice insect species, including Orseolia oryzae (Wood-Mason), Nilaparvata lugens, Recilia dorsalis, and Nephotettix nigropictus from three families (Cecidomyiidae, Cicadellidae and Delphacidae) and two main orders (Diptera and Hemiptera) were exhibited. All rice insect species mentioned could be found from the yellow sticky trap that were higher than in the bottle trap in which only O. oryzae could be only trapped. From this survey, it was indicated that the yellow sticky trap coated with pandanus palm extracts had a promising potential to use as an attractant for the detection of rice paddy insects in the next future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pandanus%20palm" title="pandanus palm">pandanus palm</a>, <a href="https://publications.waset.org/abstracts/search?q=bioattractant" title=" bioattractant"> bioattractant</a>, <a href="https://publications.waset.org/abstracts/search?q=bottle%20trap" title=" bottle trap"> bottle trap</a>, <a href="https://publications.waset.org/abstracts/search?q=yellow%20sticky%20trap" title=" yellow sticky trap"> yellow sticky trap</a> </p> <a href="https://publications.waset.org/abstracts/160235/feasibility-study-on-the-bioattactants-from-pandanus-palm-extracts-for-trapping-rice-insect-pests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160235.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">125</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">629</span> Effect of Hydrogen Content and Structure in Diamond-Like Carbon Coatings on Hydrogen Permeation Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Motonori%20Tamura">Motonori Tamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The hydrogen barrier properties of the coatings of diamond-like carbon (DLC) were evaluated. Using plasma chemical vapor deposition and sputtering, DLC coatings were deposited on Type 316L stainless steels. The hydrogen permeation rate was reduced to 1/1000 or lower by the DLC coatings. The DLC coatings with high hydrogen content had high hydrogen barrier function. For hydrogen diffusion in coatings, the movement of atoms through hydrogen trap sites such as pores in coatings, and crystal defects such as dislocations, is important. The DLC coatings are amorphous, and there are both sp3 and sp2 bonds, and excess hydrogen could be found in the interstitial space and the hydrogen trap sites. In the DLC coatings with high hydrogen content, these hydrogen trap sites are likely already filled with hydrogen atoms, and the movement of new hydrogen atoms could be limited. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20permeation" title="hydrogen permeation">hydrogen permeation</a>, <a href="https://publications.waset.org/abstracts/search?q=stainless%20steels" title=" stainless steels"> stainless steels</a>, <a href="https://publications.waset.org/abstracts/search?q=diamond-like%20carbon" title=" diamond-like carbon"> diamond-like carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20trap%20sites" title=" hydrogen trap sites"> hydrogen trap sites</a> </p> <a href="https://publications.waset.org/abstracts/63201/effect-of-hydrogen-content-and-structure-in-diamond-like-carbon-coatings-on-hydrogen-permeation-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63201.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">348</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">628</span> Numerical Analysis of Flow in the Gap between a Simplified Tractor-Trailer Model and Cross Vortex Trap Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Terrance%20Charles">Terrance Charles</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyin%20Yang"> Zhiyin Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiling%20Lu"> Yiling Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy trucks are aerodynamically inefficient due to their un-streamlined body shapes, leading to more than of 60% engine power being required to overcome the aerodynamics drag at 60 m/hr. There are many aerodynamics drag reduction devices developed and this paper presents a study on a drag reduction device called Cross Vortex Trap Device (CVTD) deployed in the gap between the tractor and the trailer of a simplified tractor-trailer model. Numerical simulations have been carried out at Reynolds number 0.51×10<sup>6</sup> based on inlet flow velocity and height of the trailer using the Reynolds-Averaged Navier-Stokes (RANS) approach. Three different configurations of CVTD have been studied, ranging from single to three slabs, equally spaced on the front face of the trailer. Flow field around three different configurations of trap device have been analysed and presented. The results show that a maximum of 12.25% drag reduction can be achieved when a triple vortex trap device is used. Detailed flow field analysis along with pressure contours are presented to elucidate the drag reduction mechanisms of CVTD and why the triple vortex trap configuration produces the maximum drag reduction among the three configurations tested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20drag" title="aerodynamic drag">aerodynamic drag</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20vortex%20trap%20device" title=" cross vortex trap device"> cross vortex trap device</a>, <a href="https://publications.waset.org/abstracts/search?q=truck" title=" truck"> truck</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynolds-Averaged%20Navier-Stokes" title=" Reynolds-Averaged Navier-Stokes"> Reynolds-Averaged Navier-Stokes</a>, <a href="https://publications.waset.org/abstracts/search?q=RANS" title=" RANS"> RANS</a> </p> <a href="https://publications.waset.org/abstracts/113731/numerical-analysis-of-flow-in-the-gap-between-a-simplified-tractor-trailer-model-and-cross-vortex-trap-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113731.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">134</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">627</span> The Effect of Meteorological Factors on the Trap Catches of Culicoides Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20Rashed">Ahmed M.

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. Also, the importance of the results on the management of these two pests is highlighted. <p class="card-text"><strong>Keywords:</strong> <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=integrated%20pest%20management" title=" integrated pest management"> integrated pest management</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20trap" title=" light trap"> light trap</a>, <a href="https://publications.waset.org/abstracts/search?q=pheromone%20trap" title=" pheromone trap"> pheromone trap</a> </p> <a href="https://publications.waset.org/abstracts/37579/management-of-jebusaea-hammerschmidtii-and-batrachedra-amydraula-on-date-palm-trees-in-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37579.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">282</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">625</span> Climate Risk Perception and Trust – Presence of a Social Trap for Willingness to Act in Favour of Climate Mitigation and Support for Renewables: A Cross-sectional Study of Four European Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lana%20Singleton">Lana Singleton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Achieving a sufficient global solution to climate change seems elusive through disappointing climate agreements and lack of cooperation. However, is this reluctance of coordination deep rooted on a more individual, societal level within countries due to a fundamental lack of social and institutional trust? The risks of climate change are illustrious and widely accepted, yet responses on an individual level are also largely inadequate. This research looks to further investigate types of trust, risk perception of climate change, and their interaction to build a greater understanding of whether a social trap (Rothstein, 2005) – where an absence of trust can overwhelm an individuals’ risk perception and result in minimal action despite knowing the dangers of no action – exists and where it is more prevalent. Presence of the social trap will be analysed for willingness to act in favour of climate change mitigation as well as attitude (acceptance) of different types of renewable energy forms. Using probit models with cross-sectional survey data on four developed European countries (UK, France, Germany, and Norway), we find evidence of the social trap in the aggregated data model, which highlights the importance of social trust regarding willingness to act in favour of climate mitigation as there is a high probability of action regardless of risk perception of climate change when social trust is high. In contrast, the same is not true for renewables, as interactions were mainly insignificant, although there were interesting findings involving institutional trust, gender, and country specific results for particular renewables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20risk" title="climate risk">climate risk</a>, <a href="https://publications.waset.org/abstracts/search?q=renewables" title=" renewables"> renewables</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20perception" title=" risk perception"> risk perception</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20trap" title=" social trap"> social trap</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20act" title=" willingness to act"> willingness to act</a> </p> <a href="https://publications.waset.org/abstracts/164622/climate-risk-perception-and-trust-presence-of-a-social-trap-for-willingness-to-act-in-favour-of-climate-mitigation-and-support-for-renewables-a-cross-sectional-study-of-four-european-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164622.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">95</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">624</span> Production Optimization through Ejector Installation at ESA Platform Offshore North West Java Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arii%20Bowo%20Yudhaprasetya">Arii Bowo Yudhaprasetya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ario%20Guritno"> Ario Guritno</a>, <a href="https://publications.waset.org/abstracts/search?q=Agus%20Setiawan"> Agus Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Recky%20Tehupuring"> Recky Tehupuring</a>, <a href="https://publications.waset.org/abstracts/search?q=Cosmas%20Supriatna"> Cosmas Supriatna </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The offshore facilities condition of Pertamina Hulu Energi Offshore North West Java (PHE ONWJ) varies greatly from place to place, depending on the characteristics of the presently installed facilities. In some locations, such as ESA platform, gas trap is mainly caused by the occurrence of flash gas phenomenon which is known as mechanical-physical separation process of multiphase flow. Consequently, the presence of gas trap at main oil line would accumulate on certain areas result in a reduced oil stream throughout the pipeline. Any presence of discrete gaseous along continuous oil flow represents a unique flow condition under certain specific volume fraction and velocity field. From gas lift source, a benefit line is used as a motive flow for ejector which is designed to generate a syphon effect to minimize the gas trap phenomenon. Therefore, the ejector’s exhaust stream will flow to the designated point without interfering other systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diffuser" title="diffuser">diffuser</a>, <a href="https://publications.waset.org/abstracts/search?q=ejector" title=" ejector"> ejector</a>, <a href="https://publications.waset.org/abstracts/search?q=flow" title=" flow"> flow</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent" title=" fluent"> fluent</a> </p> <a href="https://publications.waset.org/abstracts/38424/production-optimization-through-ejector-installation-at-esa-platform-offshore-north-west-java-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38424.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">435</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">623</span> The Emerging Multi-Species Trap Fishery in the Red Sea Waters of Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabeel%20M.%20Alikunhi">Nabeel M.

Fish traps constitute the dominant small-scale fisheries in Saudi waters of Arabian Gulf (eastern seaboard of Saudi Arabia). Recently, however, traps have been increasingly used along the Saudi Red Sea coast (western seaboard), with a coastline of 1800 km (71%) compared to only 720 km (29%) in the Saudi Gulf region. The production trend for traps indicates a recent increase in catches and percent contribution to traditional fishery landings, thus ascertaining the rapid proliferation of trap fishing along the Saudi Red Sea coast. Reef-associated fish species, mainly groupers (Serranidae), emperors (Lethrinidae), parrotfishes (Scaridae), scads and trevallies (Carangidae), and snappers (Lutjanidae), dominate the trap catches, reflecting the reef-dominated shelf zone in the Red Sea. This ongoing investigation covers following major objectives (i) Baseline studies to characterize trap fishery through landing site visit and interview surveys (ii) Stock assessment by fisheries and biological data obtained through monthly landing site monitoring using fishery operational model by FLBEIA, (iii) Operational impacts, derelict traps assessment and by-catch analysis through bottom-mounted video camera and onboard monitoring (iv) Elucidation of fishing grounds and derelict traps impacts by onboard monitoring, Remotely Operated underwater Vehicle and Autonomous Underwater Vehicle surveys; and (v) Analysis of gear design and operations which covers colonization and deterioration experiments. The progress of this investigation on the impacts of the trap fishery on fish stocks and the marine environment in the Saudi Red Sea region is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=red%20sea" title="red sea">red sea</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20trap" title=" fish trap"> fish trap</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20assessment" title=" stock assessment"> stock assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a> </p> <a href="https://publications.waset.org/abstracts/42986/the-emerging-multi-species-trap-fishery-in-the-red-sea-waters-of-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42986.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">350</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">622</span> Developers’ Gains and Losses from the Economic Incentives of Green Building: Explanations from the Transitional Gains Trap and Transaction Cost Economics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ke%20Fan">Ke Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Edwin%20H.%20W.%20Chan"> Edwin H.

However, if developers could gain from the incentives, why not all the buildings are green? This paper aims to study this problem and provide a new perspective to look at the economic incentives. The theories of Transitional Gains Trap (TGP) and Transaction Cost Economics (TCE) are employed to explain the developers’ gains and losses from the economic incentives. This paper takes the GFA (gross floor area) concession incentive in Hong Kong, which is one of the most popular incentives, as the case to conduct in-depth case study and it did interview to validate the results. The results show that after implementing the GFA concession scheme, the benefit of the GFA concession is capitalized into land value. Therefore, developers have to bear the increased land cost, which supports the theory of the TGP. Even though, some developers are still not willing to participate in the incentive scheme because of high transaction costs (TCs). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20building" title="green building">green building</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20incentives" title=" economic incentives"> economic incentives</a>, <a href="https://publications.waset.org/abstracts/search?q=transitional%20gains%20trap" title=" transitional gains trap"> transitional gains trap</a>, <a href="https://publications.waset.org/abstracts/search?q=transaction%20cost" title=" transaction cost"> transaction cost</a> </p> <a href="https://publications.waset.org/abstracts/61235/developers-gains-and-losses-from-the-economic-incentives-of-green-building-explanations-from-the-transitional-gains-trap-and-transaction-cost-economics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61235.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">291</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">621</span> Evaluation of Trapping Efficiency of Slow Released Formulations of Methyl Eugenol with Lanolin Wax against Bactrocera zonata</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Afzal%20Naveed">Waleed Afzal Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammd%20Dildar%20Gogi"> Muhammd Dildar Gogi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Sufian"> Muhammad Sufian</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Amjad%20Ali"> Muhammad Amjad Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Junaid%20Nisar"> Muhammad Junaid Nisar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mubashar%20Iqbal"> Mubashar Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Amna%20Jalal"> Amna Jalal</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Munir"> Faisal Munir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study was carried out to evaluate the performance of Slow-Released Formulations (SRF) of Methyl eugenol with Lanolin wax in orchard of the University of Agriculture Faisalabad, Pakistan against fruit flies.

MIT is characterized by declining factor productivity from the exhaustion of labor intensive, import and Foreign Direct Investment (FDI) based strategies when middle-income status is achieved. In this paper, we focus on MIT and Poland. In the past two decades, Poland experienced steady growth based largely on imported technologies and low-cost labor. Recently, that economic growth has slowed, prompting economists to ask whether Poland is experiencing MIT. To answer this question, we analyze changes in investment in Poland; specifically- its growth and composition – as well as savings, FDI, educational attainments of the labor force, development of new technologies and products, the role of imports, diversification of exports, and product complexity. We also examine the development of modern infrastructure, institutions (including legal environment) and demographic changes in Poland that support growth. Our findings indicate that certain factors consistent with MIT are gaining importance in Poland, and represent a challenge to that country’s future growth rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engines%20of%20growth" title="engines of growth">engines of growth</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20productivity" title=" factor productivity"> factor productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20income%20trap" title=" middle income trap"> middle income trap</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/77703/an-assessment-of-polands-current-macroeconomic-conditions-to-determine-whether-it-is-in-a-middle-income-trap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77703.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">211</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">619</span> Interaction of Steinernema Glaseri, an Entomopathogenic Nematode with a Predatory Fungus Arthrobotrys Superba on Different Nutrient Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Varsha%20Baweja">Varsha Baweja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steinernema glaseri is known to be the most potent biocontrol agent against a number of insect pests of various orders and of diverse habitats under laboratory conditions. But in nature many micro pathogens may affect the efficacy of such entomopathogenic nematodes. Keeping this in view, the interaction of Steinernema glaseri with a predatory fungus Arthrobotrys superba was assessed on eight different nutrient media. The activity of A.superba was evaluated in terms of trap formation, conidiophore formation, and number of adhesive cells formed in the presence and absence of nematodes. The fungus failed to form any trap on any of the culture media in the absence of nematodes. However, in the presence of nematodes, the trap formation by the test fungus was increased but the number of conidiophores decreased with increase in dilution of Corn Meal Agar from 5% to 2%. Higher number of chlamydospores were observed in phenylalanine treated medium which indicates the inhibiting effect of phenylalanine on the growth of A. superba. Our results suggest that care should be taken during release of entomopathogenic nematodes in an agroecosystem for managing various insect pests in a more efficient manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Entomopathogenic%20Nematode" title="Entomopathogenic Nematode ">Entomopathogenic Nematode </a>, <a href="https://publications.waset.org/abstracts/search?q=Steinernema%20Glaseri" title=" Steinernema Glaseri"> Steinernema Glaseri</a>, <a href="https://publications.waset.org/abstracts/search?q=Predatory%20Fungus" title=" Predatory Fungus"> Predatory Fungus</a>, <a href="https://publications.waset.org/abstracts/search?q=Arthrobotrys%20Superba" title=" Arthrobotrys Superba"> Arthrobotrys Superba</a> </p> <a href="https://publications.waset.org/abstracts/66140/interaction-of-steinernema-glaseri-an-entomopathogenic-nematode-with-a-predatory-fungus-arthrobotrys-superba-on-different-nutrient-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66140.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">278</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">618</span> Mainland China and Taiwan’s Strategies for Overcoming the Middle/High Income Trap: Domestic Consensus-Building and the Foundations of Cross-Strait Interactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mingke%20Ma">Mingke Ma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent discovery of the High-Income Trap phenomena and the established Middle-Income Trap literature have identified the similarity of the structural challenges that both Mainland China and Taiwan have been facing since the simultaneous growth slowdown from the 2000s. Mainland China and Taiwan’s ineffectiveness in productivity growth weakened their overall competitiveness in Global Value Chains. With the subsequent decline of industrial profitability, social compression from late development persists and jeopardises the social cohesion. From Ma Ying-jeou’s ‘633’ promise and Tsai Ing-wen’s ‘5+2’ industrial framework to Mainland China’s 11th to 14th Five-Year Plans, leaderships across the Strait have been striving to constitute new models for inclusive and sustainable development through policy responses. This study argues that social consensuses that have been constructed by the domestic political processes define the feasibility of the reform strategies, which further construct the conditions for Cross-Strait interactions. Based on the existing literature of New Institutional Economics, Middle/High Income Trap, and Compressed Development, this study adopts a Historical Institutionalist analytical framework to identify how the historical path-dependency contributes to the contemporary growth constraints in both economies and the political difficulty on navigating the institutional and Organisational change. It continues by tracing the political process of economic reform to examine the sustainability and resilience of the manifested social consensus that had empowered the proposed policy frameworks. Afterwards, it examines how the political outcomes in such a simultaneous process shared by both Mainland China and Taiwan construct the social, economic, institutional, and political foundations of contemporary Cross-Strait engagement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=historical%20institutionalism" title="historical institutionalism">historical institutionalism</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20economy" title=" political economy"> political economy</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-strait%20relations" title=" cross-strait relations"> cross-strait relations</a>, <a href="https://publications.waset.org/abstracts/search?q=high%2Fmiddle%20income%20trap" title=" high/middle income trap"> high/middle income trap</a> </p> <a href="https://publications.waset.org/abstracts/143225/mainland-china-and-taiwans-strategies-for-overcoming-the-middlehigh-income-trap-domestic-consensus-building-and-the-foundations-of-cross-strait-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143225.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">617</span> Glorification Trap in Combating Human Trafficking in Indonesia: An Application of Three-Dimensional Model of Anti-Trafficking Policy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kosandi">M.

Based on a research on Indonesian combat against trafficking in 2017-2018, this paper shows the tendency of misinterpretation and misapplication of the Indonesian anti-trafficking law into misusing the law for glorification, to create an image of certain extent of achievement in combating human trafficking. The objective of this paper is to explain the persistent occurrence of human trafficking crimes despite the significant progress of anti-trafficking efforts of Indonesian government. The research was conducted in 2017-2018 by qualitative approach through observation, depth interviews, discourse analysis, and document study, applying the three-dimensional model for analyzing human trafficking in the source country. This paper argues that the drive for glorification of achievement in the combat against trafficking has trapped Indonesian government in the loop of misinterpretation, misapplication, and misuse of the anti-trafficking law. In return, the so-called crime against humanity remains high and tends to increase in Indonesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20trafficking" title="human trafficking">human trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-trafficking%20policy" title=" anti-trafficking policy"> anti-trafficking policy</a>, <a href="https://publications.waset.org/abstracts/search?q=transnational%20crime" title=" transnational crime"> transnational crime</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20country" title=" source country"> source country</a>, <a href="https://publications.waset.org/abstracts/search?q=glorification%20trap" title=" glorification trap"> glorification trap</a> </p> <a href="https://publications.waset.org/abstracts/104170/glorification-trap-in-combating-human-trafficking-in-indonesia-an-application-of-three-dimensional-model-of-anti-trafficking-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104170.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">167</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">616</span> Insect Diversity Assessment of Maize Crop (Zea mays L.) by Using Sweep Net, Pitfall Trap and Plant Inspection Methods </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem%20Mushtaq">Muhammad Naeem Mushtaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Arshad"> Muhammad Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Majeed"> Shahid Majeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maize is known as queen of cereals because of its highest genetic yield potential and multipurpose characteristics in human being and animal diet.

Probably defined as the one involving emission of light from certain kinds of substances on absorbing various energies in the form of external stimulus, the phenomenon claims a versatile pertinence. First observed and reported in an extract of Ligrium Nephriticum by Monards, the phenomenon involves turning of crystal clear water into colorful fluid when comes in contact with the special wood. In words of Sir G.G. Stokes, the phenomenon actually involves three different techniques – absorption, excitation and emission. With variance in external stimulus, the corresponding luminescence phenomenon is obtained. Here, this paper gives a concise discussion of thermoluminescence which is one of the types of luminescence obtained when the external stimulus is given in form of heat energy. A deep insight of thermoluminescence put forward a qualitative analysis of various parameters such as glow curves peaks, trap depth, frequency factors and order of kinetics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20factor" title="frequency factor">frequency factor</a>, <a href="https://publications.waset.org/abstracts/search?q=glow%20curve%20peaks" title=" glow curve peaks"> glow curve peaks</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoluminescence" title=" thermoluminescence"> thermoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=trap%20depth" title=" trap depth"> trap depth</a> </p> <a href="https://publications.waset.org/abstracts/47928/a-theoretical-overview-of-thermoluminescence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47928.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">399</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">614</span> Thermoelectric Properties of Doped Polycrystalline Silicon Film</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Long">Li Long</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Ortlepp"> Thomas Ortlepp</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The transport properties of carriers in polycrystalline silicon film affect the performance of polycrystalline silicon-based devices. They depend strongly on the grain structure, grain boundary trap properties and doping concentration, which in turn are determined by the film deposition and processing conditions. Based on the properties of charge carriers, phonons, grain boundaries and their interactions, the thermoelectric properties of polycrystalline silicon are analyzed with the relaxation time approximation of the Boltz- mann transport equation. With this approach, thermal conductivity, electrical conductivity and Seebeck coefficient as a function of grain size, trap properties and doping concentration can be determined.

Hyaluronic acid (HA), chondroitin sulfate (CS) and heparin (HP) are anionic glycosaminoglycans (GCGs) which can regulate osteogenic activity. In this study, chitosan membranes were prepared by glutaraldehyde crosslinking reaction and then complexed with three different types of GCGs. 7F2 osteoblasts-like cells and macrophages Raw264.7 were used as models to study the influence of chitosan membranes on osteometabolism. Although chitosan membranes are highly hydrophilic, the membranes associated with GCG-chitosan complexes showed about 60-70% cell attachment. Furthermore, the membranes associated with HP-chitosan complexes could increase ALP activity in comparison with chitosan films only. Three types of the membranes associated with GCG-chitosan complexes could significantly inhibit LPS induced-nitric oxide expression. In addition, chitosan membranes associated with HP and HA can down-regulate tartrate-resistant acid phosphatase (TRAP) activity but not CS-chitosan complexes. Based on these results, we conclude that chitosan membranes associated with HP can increase ALP activity in osteoblasts and chitosan membranes associated with HP and HA reduce TRAP activity in osteoclasts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteoblast" title="osteoblast">osteoblast</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoclast" title=" osteoclast"> osteoclast</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=glycosaminoglycan" title=" glycosaminoglycan"> glycosaminoglycan</a> </p> <a href="https://publications.waset.org/abstracts/3820/local-activities-of-the-membranes-associated-with-glycosaminoglycan-chitosan-complexes-in-bone-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3820.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">527</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">612</span> Preliminary Treatment in Wastewater Treatment Plants: Operation and Maintenance Aspects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priscila%20M.%20Lima">Priscila M.

The high imbalance of camera trap datasets, however, results in poor accuracies for minority (rare or endangered) species due to their relative insignificance to the overall model accuracy. This paper investigates the use of Focal Loss, in comparison to the traditional Cross Entropy Loss function, to improve the identification of minority species in the “255 Bird Species” dataset from Kaggle. The results show that, although Focal Loss slightly decreased the accuracy of the majority species, it was able to increase the F1-score by 0.06 and improve the identification of the bottom two, five and ten (minority) species by 37.5%, 15.7% and 10.8%, respectively, as well as resulting in an improved overall accuracy of 2.96%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20networks" title="convolutional neural networks">convolutional neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20imbalance" title=" data imbalance"> data imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=focal%20loss" title=" focal loss"> focal loss</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20classification" title=" species classification"> species classification</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20conservation" title=" wildlife conservation"> wildlife conservation</a> </p> <a href="https://publications.waset.org/abstracts/132442/improved-rare-species-identification-using-focal-loss-based-deep-learning-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132442.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">191</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">610</span> Paleogene Syn-Rift Play Identification in Palembang Sub-Basin, South Sumatera, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Perdana%20Rakhmana%20Putra">Perdana Rakhmana Putra</a>, <a href="https://publications.waset.org/abstracts/search?q=Hansen%20Wijaya"> Hansen Wijaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sri%20Budiyani"> Sri Budiyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Natsir"> Muhamad Natsir</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20badai%20Samudra"> Alexis badai Samudra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Palembang Sub-Basin (PSB) located in southern part of South Sumatera basin (SSB) consist of half-graben complex trending N-S to NW-SE. These geometries are believe as an impact of strike-slip regime developed in Eocene-Oligocene. Generally, most of the wells in this area produced hydrocarbon from late stage of syn-rift sequences called Lower Talang Akar (LTAF) and post-rift sequences called Batu Raja Formation (BRF) and drilled to proved hydrocarbon on structural trap; three-way dip anticline, four-way dip anticline, dissected anticline, and stratigraphy trap; carbonate build-up and stratigraphic pinch out. Only a few wells reached the deeper syn-rift sequences called Lahat Formation (LAF) and Lemat Formation (LEF). The new interpretation of subsurface data was done by the tectonostratigraphy concept and focusing on syn-rift sequence. Base on seismic characteristic on basin centre, it divided into four sequences: pre-rift sequence, rift initiation, maximum rift and late rift. These sequences believed as a new exploration target on PSB mature basin. This paper will demonstrate the paleo depositional setting during Paleogene and exploration play concept of syn-rift sequence in PSB. The main play for this area consists of stratigraphic and structure play, where the stratigraphic play is Eocene-Oligocene sediment consist of LAF sandstone, LEF-Benakat formation, and LAF with pinch-out geometry. The pinch-out, lenses geometry and on-lap features can be seen on the seismic reflector and formed at the time of the syn-rift sequence. The structural play is dominated by a 3 Way Dip play related to reverse fault trap. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=syn-rift" title="syn-rift">syn-rift</a>, <a href="https://publications.waset.org/abstracts/search?q=tectono-stratigraphy" title=" tectono-stratigraphy"> tectono-stratigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration%20play" title=" exploration play"> exploration play</a>, <a href="https://publications.waset.org/abstracts/search?q=basin%20center%20play" title=" basin center play"> basin center play</a>, <a href="https://publications.waset.org/abstracts/search?q=south%20sumatera%20basin" title=" south sumatera basin"> south sumatera basin</a> </p> <a href="https://publications.waset.org/abstracts/88167/paleogene-syn-rift-play-identification-in-palembang-sub-basin-south-sumatera-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88167.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">194</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">609</span> Real-Space Mapping of Surface Trap States in Cigse Nanocrystals Using 4D Electron Microscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riya%20Bose">Riya Bose</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashok%20Bera"> Ashok Bera</a>, <a href="https://publications.waset.org/abstracts/search?q=Manas%20R.%20Parida"> Manas R.

The surface of the nanocrystals plays a key role in controlling their applicability for light emitting and light harvesting purposes. Typically for quaternary systems like CIGSe, which have many desirable attributes to be used for optoelectronic applications, relative abundance of surface trap states acting as non-radiative recombination centre for charge carriers remains as a major bottleneck preventing further advancements and commercial exploitation of these nanocrystals devices. Though ultrafast spectroscopic techniques allow determining the presence of picosecond carrier trapping channels, because of relative larger penetration depth of the laser beam, only information mainly from the bulk of the nanocrystals is obtained. Selective mapping of such ultrafast dynamical processes on the surfaces of nanocrystals remains as a key challenge, so far out of reach of purely optical probing time-resolved laser techniques. In S-UEM, the optical pulse generated from a femtosecond (fs) laser system is used to generate electron packets from the tip of the scanning electron microscope, instead of the continuous electron beam used in the conventional setup. This pulse is synchronized with another optical excitation pulse that initiates carrier dynamics in the sample. The principle of S-UEM is to detect the secondary electrons (SEs) generated in the sample, which is emitted from the first few nanometers of the top surface. Constructed at different time delays between the optical and electron pulses, these SE images give direct and precise information about the carrier dynamics on the surface of the material of interest. In this work, we report selective mapping of surface dynamics in real space and time of CIGSe nanocrystals applying 4D S-UEM. We show that the trap states can be considerably passivated by ZnS shelling of the nanocrystals, and the carrier dynamics can be significantly slowed down. We also compared and discussed the S-UEM kinetics with the carrier dynamics obtained from conventional ultrafast time-resolved techniques. Additionally, a direct effect of the state trap removal can be observed in the enhanced photoresponse of the nanocrystals after shelling. Direct observation of surface dynamics will not only provide a profound understanding of the photo-physical mechanisms on nanocrystals’ surfaces but also enable to unlock their full potential for light emitting and harvesting applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=4D%20scanning%20ultrafast%20microscopy" title="4D scanning ultrafast microscopy">4D scanning ultrafast microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=charge%20carrier%20dynamics" title=" charge carrier dynamics"> charge carrier dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocrystals" title=" nanocrystals"> nanocrystals</a>, <a href="https://publications.waset.org/abstracts/search?q=optoelectronics" title=" optoelectronics"> optoelectronics</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20passivation" title=" surface passivation"> surface passivation</a>, <a href="https://publications.waset.org/abstracts/search?q=trap%20states" title=" trap states"> trap states</a> </p> <a href="https://publications.waset.org/abstracts/52428/real-space-mapping-of-surface-trap-states-in-cigse-nanocrystals-using-4d-electron-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52428.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">295</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">608</span> Trapped Versus Stepping Stones: Work Trajectories of Young Workers During the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Goh%20Mingyuan%20Asher">Goh Mingyuan Asher</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Fadiah%20Johari"> Nurul Fadiah Johari</a>, <a href="https://publications.waset.org/abstracts/search?q=Neo%20Yu%20Wei"> Neo Yu Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Aryung"> Kim Aryung</a>, <a href="https://publications.waset.org/abstracts/search?q=Ho%20Kong%20Chong"> Ho Kong Chong</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Y.%20H.%20N.%20G."> Irene Y.

The paper drew insights from two interview waves of the in-work poverty study in Singapore which were conducted a year apart. By analysing respondents’ job histories before and at the start of the pandemic as well as their job experiences over the two waves of interviews, the study found the presence of what scholars describe as trap and stepping stone trajectories. Trap trajectories refer to how the nature of precarious employment leads respondents to be in dead-end jobs with no room for progression while stepping stone trajectories refer to how poor work provides opportunities for the accumulation of work experiences. We also look at how structure, agency and biographical factors affect job trajectories and discuss the impacts of COVID-19 on work experiences and the implications of the bifurcation of trajectory outcomes on poverty and inequality among the young working poor in Singapore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=working%20poor" title="working poor">working poor</a>, <a href="https://publications.waset.org/abstracts/search?q=precarity" title=" precarity"> precarity</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20workers" title=" young workers"> young workers</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20trajectories" title=" work trajectories"> work trajectories</a> </p> <a href="https://publications.waset.org/abstracts/156032/trapped-versus-stepping-stones-work-trajectories-of-young-workers-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156032.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">99</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">607</span> Intertidal Fixed Stake Net Trap (Hadrah) Fishery in Kuwait, Distribution, Catch Rate, and Species Composition </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20F.%20Al-Baz">Ali F.

This study described the hadrah fishery in Kuwait. From October 2001 to December 2002, more than 37,372 specimens representing 95 species (89 fish, 2 mollusks, 4 crustaceans) were measured from hadrah located in three different areas along Kuwait's coast. In Kuwait Bay, catch rates averaged 62 kg/sir day (range 14 kg/sir-day in February to 160 kg/sir-day in October 2002). Commercial species accounted for 41% of the catches. Catches from Failakah Island averaged 96 kg/sir-day from June through September, with 61% of the catch being commercial species. In the southern area, catches averaged only 32 kg/sir-day, and only 34% were commercially important. Forty percent of the hadrah catches were juveniles which shows that the shallow intertidal waters are prime nursery habitat, particularly in Kuwait Bay. To maintain ecosystem biodiversity and recruitment success of the fishes, we recommended that all hadrah should be removed from Kuwait Bay. In the future, removal of hadrah in other locations should be considered. <p class="card-text"><strong>Keywords:</strong> <a
