However, there are still some problems in the existing models to link the on the first, the hydrodynamics of waves and currents and secondly, the sediment transport processes and due to the variability in time, space and interaction and the simultaneous action of wave-current near the shore. This paper is the establishment of a numerical modeling to forecast the sediment transport from development scenarios of harbor structure. It is established on the basis of a numerical simulation of a water-sediment model via a 2D model using a set of codes calculation MIKE 21-DHI software. This is to examine the effect of the sediment transport drivers following the dominant incident wave in the direction to pass input harbor work under different variants planning studies to find the technical and economic limitations to the sediment transport and protection of the harbor structure optimum solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swell" title="swell">swell</a>, <a href="https://publications.waset.org/abstracts/search?q=current" title=" current"> current</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation" title=" radiation"> radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh" title=" mesh"> mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=mike21" title=" mike21"> mike21</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a> </p> <a href="https://publications.waset.org/abstracts/16069/numerical-modeling-of-waves-and-currents-by-using-a-hydro-sedimentary-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16069.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">469</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">60</span> The Impact of Ship Traffic and Harbor Activities on the Atmospheric Pollution in Two Northern Adriatic Ports: Venice and Rijeka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Barbaro">Elena Barbaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Gregoris"> Elena Gregoris</a>, <a href="https://publications.waset.org/abstracts/search?q=Rossano%20Piazza"> Rossano Piazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Boris%20Mifka"> Boris Mifka</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatjana%20Ivo%C5%A1evi%C4%87"> Tatjana Ivošević</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivo%20Orli%C4%87"> Ivo Orlić</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Alebi%C4%87-Jureti%C4%87"> Ana Alebić-Juretić</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Gambaro"> Andrea Gambaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Contini"> Daniele Contini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the POSEIDON project is to quantify the relative contribution of maritime traffic and harbor activities to atmospheric pollutants concentration in four port-cities of the Adriatic Sea.

To compare the structures of bones of two study species; first, the Spinous Process (SP), Inferior Articular Process (IAP), Laminae Vertebrae (LA), Foramen Vertebrae (FV), Corpus Vertebrae (CV), Transverse Process (TP) were determined and then the length of the Spinous Process (LSP), length of the Foramen Vertebrae (LFV), area of the Corpus Vertebrae (ACV), and length of the Transverse Process (LTP) were measured from the caudal view. The spine consists of a total of 61 vertebrae (7 cervical, 13 thoracic, 14 lumbar, and 27 caudal vertebrae) in the Common bottlenose dolphin, while the Harbor Porpoise has 63 vertebrae (7 cervical, 12 thoracic, 14 lumbar, 30 caudal. In the Common bottlenose dolphin, epiphyseal ossification was between the 21st caudal vertebra and the 27th caudal vertebra, while in the Harbor porpoise, it was observed in all vertebrae. Ankylosing spondylitis was observed in the C1 and C2 vertebrae in the Common bottlenose dolphin and in all cervical vertebrae between C1 and C6 in the Harbor porpoise. We argue that this difference in fused cervical vertebrae between the two species may be due to the fact that the neck movements of the Harbor porpoise in the vertical and horizontal axes are more limited than those of the Common bottlenose dolphin. We also think that as the number of fused cervical vertebrae increases, underwater maneuvers are performed at a wider angle, but to test this idea, we think that different species of dolphins should be compared and the different age groups should be investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometry" title=" morphometry"> morphometry</a>, <a href="https://publications.waset.org/abstracts/search?q=vertebrae" title=" vertebrae"> vertebrae</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20bottlenose%20dolphin" title=" common bottlenose dolphin"> common bottlenose dolphin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tursiops%20truncatus" title=" Tursiops truncatus"> Tursiops truncatus</a>, <a href="https://publications.waset.org/abstracts/search?q=harbour%20porpoise" title=" harbour porpoise"> harbour porpoise</a>, <a href="https://publications.waset.org/abstracts/search?q=Phocoena%20phocoena" title=" Phocoena phocoena"> Phocoena phocoena</a> </p> <a href="https://publications.waset.org/abstracts/186749/morphological-comparison-of-the-total-skeletal-of-common-bottlenose-dolphin-tursiops-truncatus-and-harbour-porpoise-phocoena-phocoena" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186749.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">48</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">58</span> Formulation of Aggregates Based on Dredged Sand and Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nor-Edine%20Abriak">Nor-Edine Abriak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilyas%20Ennahal"> Ilyas Ennahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdeljalil%20Zri"> Abdeljalil Zri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahfoud%20Benzerzour"> Mahfoud Benzerzour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nord Pas de Calais is one of the French regions that records a large volume of dredged sediment in harbors and waterways. To ensure navigation within ports and waterways, harbor and river managers are forced to find solutions to remove sediment that contamination levels exceed levels established by regulations. Therefore, this non- submersible sediment must be managed on land and will be subject to the waste regulation. In this paper, some examples of concrete achievements and experiments of reusing dredged sediment in civil engineering and sector will be illustrated. These achievements are alternative solutions to sediment landfilling and guarantee the reuse of this material in a logic of circular economy and ecological transition. It permits to preserve the natural resources increasingly scarce and resolve issues related to the accumulation of sediments in the harbor basins, rivers, dams, and lakes, etc. Examples of beneficial use of dredged material illustrated in this paper are the result of different projects reusing harbor and waterways sediments in several applications. These projects were funded under the national SEDIMATERIAUX approach. Thus the technical and environmental feasibility of the reuse of dredged sediment is demonstrated and verified; the dredged sediment reusing would meet multiple challenges of sustainable development in relation to environmental, economic, social and societal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20economy" title="circular economy">circular economy</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=SEDIMATERIAUX" title=" SEDIMATERIAUX"> SEDIMATERIAUX</a>, <a href="https://publications.waset.org/abstracts/search?q=waterways" title=" waterways"> waterways</a> </p> <a href="https://publications.waset.org/abstracts/77256/formulation-of-aggregates-based-on-dredged-sand-and-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77256.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">156</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">57</span> Benthic Foraminiferal Responses to Coastal Pollution for Some Selected Sites along Red Sea, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramadan%20M.%20El-Kahawy">Ramadan M.

Grain size analyses indicate that the bottom facies in the inner part of quseir is muddy while the inner part of Ras Gharib and Safaga is silty sand and those close to the entrance of Safaga bay and Ras Gharib is sandy facies while quseir still also muddy facies. geochemical data show high concentration of heavy-metals mainly in Ras Gharib due to oil leakage from the hydrocarbon oil field and Safaga bay due to the phosphate mining while quseir is medium concentration due to anthropocentric effect.micropaelontological analyses indicate the boundaries of the highest concentration of heavy metals and those of low concentration as well.the dominant benthic foraminifera in these three sites are Ammonia beccarii, Amphistigina and sorites. the study highlights the worsening of environmental conditions and also show that the areas in need of a priority recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benthic%20foraminifera" title="benthic foraminifera">benthic foraminifera</a>, <a href="https://publications.waset.org/abstracts/search?q=Ras%20Gharib" title=" Ras Gharib"> Ras Gharib</a>, <a href="https://publications.waset.org/abstracts/search?q=Safaga" title=" Safaga"> Safaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Quseir" title=" Quseir"> Quseir</a>, <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=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/14580/benthic-foraminiferal-responses-to-coastal-pollution-for-some-selected-sites-along-red-sea-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14580.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">56</span> Assessment of Trace Metals Contamination in Surficial and Core Sediments from Ghannouch- Gabes Coastline, Impact of Phosphogypsum Discharge, Southeastern of Tunisia, Mediterranean Sea: Geochemical and Mineralogical Approaches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Ben%20Amor">Rim Ben Amor</a>, <a href="https://publications.waset.org/abstracts/search?q=Myriam%20Abidi"> Myriam Abidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Moncef%20Gueddari"> Moncef Gueddari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the present study is to assess the level and the distribution of CaO, SO3, Cd, Cu, Pb and Zn incore sediments of Ghannouch-Gabes coast, Gulf of Gabes, Tunisian Mediterranean coast. The XRD analyses indicate that the sediments of Ghannouch-Gabes coast are mainly composed of quartz, calcite, gypsum and fluorine reflecting the impact of the phosphate fertilizer industrial waste. The vertical distribution of surface sediments shows for all the elements analyzed, that the area located between the commercial and the fishing port of Gabes, is the most polluted zone, where the two harbors acted as barriers and limited the dispersion of phosphogypsum discharge. The abundance order of metals was found to be Zn > Cd > Cu >Pb and that the highest levels of heavy metals were found in the uppermost segment of the sediment core compared to lower depth subsurface due to a continuous input of PG release and showed that the area between the two harbor suffered from several types of pollutants compared to reference core C1, collected from non-industrialized area. The level of pollution was evaluated using contamination factor (Cf), pollution load index (PLI) and the geoaccumulation index (Igeo). The obtained results of Igeo allowed us to distinguish that the area between the commercial harbor of Ghannouch and the fishing harbor of Gabes is the most polluted where sediments are strongly contaminated for Pb, Cu and Cd. The pollution load index (PLI) of all sediments collected classified them as "polluted". According to contamination factor (Cf), the sediments can be considered as ‘considerable’ to ‘very high’ contaminated for Pb, ‘very high to moderate’ for Cd, ‘ moderate’ for Zn, between ‘moderate’ and ‘considerable’ for Cu. Statistical analyses show that heavy metals, fluoride, calcium and sulphate are resulting from the same anthropogenic origin. The metallic pollution status of sediments of Ghanouch -Gabes coast is worrying and requires a serious intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title="trace metals">trace metals</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphogypsum" title=" phosphogypsum"> phosphogypsum</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20sediments" title=" core sediments"> core sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=accumulation%20factor" title=" accumulation factor"> accumulation factor</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination%20factor" title=" contamination factor"> contamination factor</a> </p> <a href="https://publications.waset.org/abstracts/73427/assessment-of-trace-metals-contamination-in-surficial-and-core-sediments-from-ghannouch-gabes-coastline-impact-of-phosphogypsum-discharge-southeastern-of-tunisia-mediterranean-sea-geochemical-and-mineralogical-approaches" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73427.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Extracellular Enzymes from Halophilic Bacteria with Potential in Agricultural Secondary Flow Recovery Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madalin%20Enache">Madalin Enache</a>, <a href="https://publications.waset.org/abstracts/search?q=Simona%20Neagu"> Simona Neagu</a>, <a href="https://publications.waset.org/abstracts/search?q=Roxana%20Cojoc"> Roxana Cojoc</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioana%20Gomoiu"> Ioana Gomoiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Delia%20Ionela%20Dobre"> Delia Ionela Dobre</a>, <a href="https://publications.waset.org/abstracts/search?q=Ancuta%20Roxana%20Trifoi"> Ancuta Roxana Trifoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various types of halophilic and halotolerant microorganisms able to be cultivated in laboratory on culture media with a wide range of sodium chloride content are isolated from several salted environments. The extracellular enzymes of these microorganisms showed the enzymatic activity in these spectrums of salinity thus being attractive for several biotechnological processes developed at high ionic strength. In present work, a number of amylase, protease, esterase, lipase, cellulase, pectinase, xilanases and innulinase were identified for more than 50th bacterial strains isolated from water samples and sapropelic mud from four saline and hypersaline lakes located in Romanian plain. On the other hand, the cellulase and pectinase activity were also detected in some halotolerant microorganisms isolated from secondary agricultural flow of grapes processing. The preliminary data revealed that from totally tested strains seven harbor proteases activity, eight amylase activity, four for esterase and another four for lipase, three for pectinase and for one strain were identified either cellulase or pectinase activity. There were no identified enzymes able to hydrolase innulin added to culture media. Several strains isolated from sapropelic mud showed multiple extracellular enzymatic activities, namely three strains harbor three activities and another seven harbor two activities. The data revealed that amylase and protease activities were frequently detected if compare with other tested enzymes. In the case of pectinase were investigated, their ability to be used for increasing resveratrol recovery from material resulted after grapes processing. In this way, the resulted material from grapes processing was treated with microbial supernatant for several times (two, four and 24 hours) and the content of resveratrol was detected by High Performance Liquid Chromatography method (HPLC). The preliminary data revealed some positive results of this treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=halophilic%20microorganisms" title="halophilic microorganisms">halophilic microorganisms</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymes" title=" enzymes"> enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=pectinase" title=" pectinase"> pectinase</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a> </p> <a href="https://publications.waset.org/abstracts/76741/extracellular-enzymes-from-halophilic-bacteria-with-potential-in-agricultural-secondary-flow-recovery-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76741.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">54</span> Using Human-Digestive Simulator to Harbor Encapsulated Lactobacillus casei 01 along with Pasteurized-Purple-Rice Drinks for Examination of the Health-Promoting Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srivilai%20Worametrachanon">Srivilai Worametrachanon</a>, <a href="https://publications.waset.org/abstracts/search?q=Arunee%20Apichartsrangkoon"> Arunee Apichartsrangkoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiranat%20Techarang"> Jiranat Techarang</a>, <a href="https://publications.waset.org/abstracts/search?q=Boonrak%20Phanchaisri"> Boonrak Phanchaisri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A human-digestive simulator consisted of four colon compartments, i.e., stomach, small intestine, proximal colon and distal colon used to harbor L. casei 01 plus either pasteurized ordinary-purple-rice drinks or germinated-purple-rice drinks.

L. casei 01 plus purple-rice drinks gave rise to significantly high formation (P ≤ 0.05) of short-chain-fatty acids (SCFA) of which highest acetic acid was found followed by propionic and butyric acids, while the germinated-rice drink showed the greatest impact. Moreover, the effect was more pronounced upon prolonged fermentation. In addition, the influence of treatments on colon microbes was also demonstrated. Accordingly, desirable bacteria including colon Lactobacilli and Bifidobacteria were significantly increased (P ≤ 0.05) in both colons in comparison with the control and the effect was more prominent after adding purple-rice drink. On the other hand, undesirable Clostridia and coliforms were apparently diminished by the influence of treatment conditions, in which both compartments exhibited similar results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-digestive%20simulator" title="human-digestive simulator">human-digestive simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactobacillus%20casei%2001" title=" Lactobacillus casei 01"> Lactobacillus casei 01</a>, <a href="https://publications.waset.org/abstracts/search?q=Pasteurized-purple-rice%20drinks" title=" Pasteurized-purple-rice drinks"> Pasteurized-purple-rice drinks</a> </p> <a href="https://publications.waset.org/abstracts/14142/using-human-digestive-simulator-to-harbor-encapsulated-lactobacillus-casei-01-along-with-pasteurized-purple-rice-drinks-for-examination-of-the-health-promoting-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14142.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">222</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">53</span> Analysis of Network Connectivity for Ship-To-Ship Maritime Communication Using IEEE 802.11 on Maritime Environment of Tanjung Perak, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Fauzi%20Makarim">Ahmad Fauzi Makarim</a>, <a href="https://publications.waset.org/abstracts/search?q=Okkie%20Puspitorini"> Okkie Puspitorini</a>, <a href="https://publications.waset.org/abstracts/search?q=Hani%27ah%20Mahmudah"> Hani'ah Mahmudah</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Adi%20Siswandari"> Nur Adi Siswandari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ari%20Wijayanti"> Ari Wijayanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a maritime country, Indonesia needs a solution in maritime connectivity which can assist the maritime communication system which including communication from harbor to the ship or ship to ship.

Concerning the wave dispating issue, Ningbo government firstly introduced Spartina alterniflora in 1980s. In the 1990s, S. alterniflora spread so rapidly thus a ‘grassland’ in the sea has been created nowadays. It has become the most important invasive plant of China’s coastal tidal flats. Although S. alterniflora had some ecological and economic functions, it has also brought series of hazards. It has ecological hazards on many aspects, including biomass and biodiversity, hydrodynamic force and sedimentation process, nutrient cycling of tidal flat, succession sequence of soil and plants and so on. On engineering, it courses problems of poor drainage and channel blocking. On economy, the hazard mainly reflected in the threat on aquaculture industry. The purpose of this study is to explore an ecological, feasible and economical way to manage Spartina alterniflora and use the land formed by it, taking Xihu Harbor in Xiangshan County as a case. Comparison method, mathematical modeling, qualitative and quantitative analysis are utilized to proceed the study. Main outcomes are as follows. By comparing a series of S. alterniflora managing methods which include the combination of mechanical cutting and hydraulic reclamation, waterlogging, herbicide and biological substitution from three standpoints – ecology, engineering and economy. It is inferred that the combination of mechanical cutting and hydraulic reclamation is among the top rank of S. alternifora managing methods. The combination of mechanical cutting and hydraulic reclamation means using large-scale mechanical equipment like large screw seagoing dredger to excavate the S. alterniflora with root and mud together. Then the mix of mud and grass was blown off nearby coastal tidal zone transported by pipelines, which can cushion the silt of tidal zone to form a land. However, as man-made land by coast, the reclamation area’s ecological sensitivity is quite high and will face high possibility of flood threat. Therefore, the reclamation area has many reasonability requirements, including ones on location, specific scope, water surface rate, direction of main watercourse, site of water-gate, the ratio of ecological land to urban construction land. These requirements all became important basis when the planning was being made. The water system planning, green space system planning, road structure and land use all need to accommodate the ecological requests. Besides, the profits from the formed land is the managing project’s source of funding, so how to utilize land efficiently is another considered point in the planning. It is concluded that by aiming at managing a large area of S. alterniflora, the combination of mechanical cutting and hydraulic reclamation is an ecological, feasible and economical method. The planning of reclamation area should fully respect the natural environment and possible disasters. Then the planning which makes land use efficient, reasonable, ecological will promote the development of the area’s city construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecological%20management" title="ecological management">ecological management</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20planning%20method" title=" ecological planning method"> ecological planning method</a>, <a href="https://publications.waset.org/abstracts/search?q=reclamation%20area" title=" reclamation area"> reclamation area</a>, <a href="https://publications.waset.org/abstracts/search?q=Spartina%20alternifora" title=" Spartina alternifora"> Spartina alternifora</a>, <a href="https://publications.waset.org/abstracts/search?q=Xihu%20harbor" title=" Xihu harbor"> Xihu harbor</a> </p> <a href="https://publications.waset.org/abstracts/45795/ecological-planning-method-of-reclamation-area-based-on-ecological-management-of-spartina-alterniflora-a-case-study-of-xihu-harbor-in-xiangshan-county" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45795.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">309</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">51</span> Environmental Restoration Science in New York Harbor - Community Based Restoration Science Hubs, or “STEM Hubs”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lauren%20B.%20Birney">Lauren B. Birney</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project utilizes the Billion Oyster Project (BOP-CCERS) place-based “restoration through education” model to promote computational thinking in NYC high school teachers and their students. Key learning standards such as Next Generation Science Standards and the NYC CS4All Equity and Excellence initiative are used to develop a computer science curriculum that connects students to their Harbor through hands-on activities based on BOP field science and educational programming. Project curriculum development is grounded in BOP-CCERS restoration science activities and data collection, which are enacted by students and educators at two Restoration Science STEM Hubs or conveyed through virtual materials. New York City Public School teachers with relevant experience are recruited as consultants to provide curriculum assessment and design feedback. The completed curriculum units are then conveyed to NYC high school teachers through professional learning events held at the Pace University campus and led by BOP educators. In addition, Pace University educators execute the Summer STEM Institute, an intensive two-week computational thinking camp centered on applying data analysis tools and methods to BOP-CCERS data. Both qualitative and quantitative analyses were performed throughout the five-year study. STEM+C – Community Based Restoration STEM Hubs. STEM Hubs are active scientific restoration sites capable of hosting school and community groups of all grade levels and professional scientists and researchers conducting long-term restoration ecology research. The STEM Hubs program has grown to include 14 STEM Hubs across all five boroughs of New York City and focuses on bringing in-field monitoring experience as well as coastal classroom experience to students. Restoration Science STEM Hubs activities resulted in: the recruitment of 11 public schools, 6 community groups, 12 teachers, and over 120 students receiving exposure to BOP activities. Field science protocols were designed exclusively around the use of the Oyster Restoration Station (ORS), a small-scale in situ experimental platforms which are suspended from a dock or pier. The ORS is intended to be used and “owned” by an individual school, teacher, class, or group of students, whereas the STEM Hub is explicitly designed as a collaborative space for large-scale community-driven restoration work and in-situ experiments. The ORS is also an essential tool in gathering Harbor data from disparate locations and instilling ownership of the research process amongst students. As such, it will continue to be used in that way. New and previously participating students will continue to deploy and monitor their own ORS, uploading data to the digital platform and conducting analysis of their own harbor-wide datasets. Programming the STEM Hub will necessitate establishing working relationships between schools and local research institutions. NYHF will provide introductions and the facilitation of initial workshops in school classrooms. However, once a particular STEM Hub has been established as a space for collaboration, each partner group, school, university, or CBO will schedule its own events at the site using the digital platform’s scheduling and registration tool. Monitoring of research collaborations will be accomplished through the platform’s research publication tool and has thus far provided valuable information on the projects’ trajectory, strategic plan, and pathway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20science" title="environmental science">environmental science</a>, <a href="https://publications.waset.org/abstracts/search?q=citizen%20science" title=" citizen science"> citizen science</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM" title=" STEM"> STEM</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/151705/environmental-restoration-science-in-new-york-harbor-community-based-restoration-science-hubs-or-stem-hubs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151705.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">96</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">50</span> Improve Divers Tracking and Classification in Sonar Images Using Robust Diver Wake Detection Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Tarek%20Al%20Muallim">Mohammad Tarek Al Muallim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozhan%20Duzenli"> Ozhan Duzenli</a>, <a href="https://publications.waset.org/abstracts/search?q=Ceyhun%20Ilguy"> Ceyhun Ilguy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Harbor protection systems are so important. The need for automatic protection systems has increased over the last years. Diver detection active sonar has great significance. It used to detect underwater threats such as divers and autonomous underwater vehicle. To automatically detect such threats the sonar image is processed by algorithms. These algorithms used to detect, track and classify of underwater objects. In this work, divers tracking and classification algorithm is improved be proposing a robust wake detection method. To detect objects the sonar images is normalized then segmented based on fixed threshold. Next, the centroids of the segments are found and clustered based on distance metric. Then to track the objects linear Kalman filter is applied. To reduce effect of noise and creation of false tracks, the Kalman tracker is fine tuned. The tuning is done based on our active sonar specifications. After the tracks are initialed and updated they are subjected to a filtering stage to eliminate the noisy and unstable tracks. Also to eliminate object with a speed out of the diver speed range such as buoys and fast boats. Afterwards the result tracks are subjected to a classification stage to deiced the type of the object been tracked. Here the classification stage is to deice wither if the tracked object is an open circuit diver or a close circuit diver. At the classification stage, a small area around the object is extracted and a novel wake detection method is applied. The morphological features of the object with his wake is extracted. We used support vector machine to find the best classifier. The sonar training images and the test images are collected by ARMELSAN Defense Technologies Company using the portable diver detection sonar ARAS-2023. After applying the algorithm to the test sonar data, we get fine and stable tracks of the divers. The total classification accuracy achieved with the diver type is 97%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=harbor%20protection" title="harbor protection">harbor protection</a>, <a href="https://publications.waset.org/abstracts/search?q=diver%20detection" title=" diver detection"> diver detection</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20sonar" title=" active sonar"> active sonar</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20detection" title=" wake detection"> wake detection</a>, <a href="https://publications.waset.org/abstracts/search?q=diver%20classification" title=" diver classification"> diver classification</a> </p> <a href="https://publications.waset.org/abstracts/70043/improve-divers-tracking-and-classification-in-sonar-images-using-robust-diver-wake-detection-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70043.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">238</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">49</span> Implicit Bias as One Obstacle to Gender Equity </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kellina%20Craig-Henderson">Kellina Craig-Henderson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, there is increased attention to the role of social perceptions in the selection, hiring, and management of employees and the evaluation and promotion of students.

Research in the social and psychological sciences reveals that implicit biases against women unfairly disadvantage them in academic and work settings. This presentation will provide an overview of the current state of knowledge on an implicit bias as well as the problems associated with it.

The maintenance dredging material derived from the port may be disposed at sea or on land in accordance with relevant state and commonwealth regulations. For the land disposal, the dredged mud slurry is hydraulically placed into containment ponds and left to undergo sedimentation and self-weight consolidation to form fill material for land reclamation.

BOP-CCERS gives students an opportunity to learn hands-on about environmental stewardship as well as environmental law and policy by giving students real responsibility. The purpose of this REU will allow for the BOP CCERS Project to further broaden its parameters into the focus of environmental law and policy where further change can be affected. Creating opportunities for undergraduates to work collaboratively with graduate students in law and policy and envision themselves in STEM careers in the field of law continues to be of importance in this project. More importantly, creating opportunities for underrepresented students to pursue careers in STEM Education has been a goal of the project over the last ten years. By raising the level of student interest in community-based citizen science integrated into environmental law and policy, a more diversified workforce will be fostered through the momentum of this dynamic program. The continuing climate crisis facing our planet calls for 21st-century skill development that includes learning and innovation skills derived from critical thinking, which will help REU students address the issues of climate change facing our planet. The demand for a climate-friendly workforce will continue to be met through this community-based citizen science effort. Environmental laws and policies play a crucial role in protecting humans, animals, resources, and habitats. Without these laws, there would be no regulations concerning pollution or contamination of our waterways. Environmental law serves as a mechanism to protect the land, air, water, and soil of our planet. To protect the environment, it is crucial that future policymakers and legal experts both understand and value the importance of environmental protection. The Environmental Law and Policy REU provides students with the opportunity to learn, through hands-on work, the skills, and knowledge needed to help foster a legal workforce centered around environmental protection while participating alongside the BOP CCERS researchers in order to gain research experience. Broadening this area to law and policy will further increase these opportunities and permit students to ultimately affect and influence larger-scale change on a global level while further diversifying the STEM workforce. Students’ findings will be shared at the annual STEM Institute at Pace University in August 2022. Basic research methodologies include qualitative and quantitative analysis performed by the research team. Early findings indicate that providing students with an opportunity to experience, explore and participate in environmental science programs such as these enhances their interests in pursuing STEM careers in Law and Policy, with the focus being on providing opportunities for underserved, marginalized, and underrepresented populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20restoration%20science" title="environmental restoration science">environmental restoration science</a>, <a href="https://publications.waset.org/abstracts/search?q=citizen%20science" title=" citizen science"> citizen science</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20law%20and%20policy" title=" environmental law and policy"> environmental law and policy</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20education" title=" STEM education"> STEM education</a> </p> <a href="https://publications.waset.org/abstracts/151647/creating-an-impact-through-environmental-law-and-policy-with-a-focus-on-environmental-science-restoration-with-social-impacts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151647.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">102</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">44</span> Biomonitoring of Marine Environment by Using a Bioindicator Donax trunculus (Mollusca, Bivalvia) from the Gulf of Annaba (Algeria): Biomarkers Responses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karima%20Sifi">Karima Sifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Soltani"> Noureddine Soltani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Annaba gulf is the most important touristic and economic area located on the east coast of Algeria. However, these fishery resources are threatened by the pollution due to the progress of economic activity. As part of a biomonitoring program on the quality of waters of the Gulf of Annaba, the specific activity of two biomarkers, acetylcholinesterase (AChE) and glutathion S-transferase (GST) has been measured in edible bivalve Donax trunculus. The samples have been collected during the year 2013 in two sites: El Battah, distant from polluted sources, and Sidi Salem, located near the harbor and different industrial waste. The results showed a significant inhibition of AChE activity and a significant increase in the activity of the GST in samples collected from Sidi Salem as compared to El Battah. The inhibition of the AChE and the increase of the GST in Sidi Salem are in relation with the level of exposition of this site to the pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donax%20trunculus" title="Donax trunculus">Donax trunculus</a>, <a href="https://publications.waset.org/abstracts/search?q=annaba%20gulf" title=" annaba gulf"> annaba gulf</a>, <a href="https://publications.waset.org/abstracts/search?q=acetylcholinesterase" title=" acetylcholinesterase"> acetylcholinesterase</a>, <a href="https://publications.waset.org/abstracts/search?q=glutathion%20s-transferase" title=" glutathion s-transferase"> glutathion s-transferase</a>, <a href="https://publications.waset.org/abstracts/search?q=biomonitoring" title=" biomonitoring"> biomonitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a> </p> <a href="https://publications.waset.org/abstracts/31216/biomonitoring-of-marine-environment-by-using-a-bioindicator-donax-trunculus-mollusca-bivalvia-from-the-gulf-of-annaba-algeria-biomarkers-responses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31216.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">387</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">43</span> Modelling Suspended Solids Transport in Dammam (Saudi Arabia) Coastal Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussam%20Alrabaiah">Hussam Alrabaiah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Some new projects (new proposed harbor, recreational projects) are considered in the eastern coasts of Dammam city, Saudi Arabia.

Similar to other genetically isolated founder populations, the Roma harbor a number of unique or rare genetic disorders. This paper discusses about a rare form of Charcot-Marie-Tooth disease – type 4G (CMT4G), also called Hereditary Motor and Sensory Neuropathy type Russe, an autosomal recessive disease caused by mutation private to Roma characterized by abnormally increased density of non-myelinated axons. CMT4G was originally found in Bulgarian Roma and in 2009 two putative causative mutations in the HK1 gene were identified. Since then, several cases were reported in Roma families mainly from Bulgaria and Spain. Here we present a Slovak Roma family in which CMT4G was diagnosed on the basis of clinical examination and genetic testing. This case is a further proof of the role of the HK1 gene in pathogenesis of the disease. It confirms that mutation in the HK1 gene is a common cause of autosomal recessive CMT disease in Roma and should be considered as a common part of a diagnostic procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gypsies" title="gypsies">gypsies</a>, <a href="https://publications.waset.org/abstracts/search?q=HK1" title=" HK1"> HK1</a>, <a href="https://publications.waset.org/abstracts/search?q=HSMN-Russe" title=" HSMN-Russe"> HSMN-Russe</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20disease" title=" rare disease"> rare disease</a> </p> <a href="https://publications.waset.org/abstracts/14738/cmt4g-rare-form-of-charcot-marie-tooth-disease-in-slovak-roma-patient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14738.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">388</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">41</span> Influence of Chemical Pollution on Thermal Habitats of the Ciliate Tetrahymena thermophila</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doufoungognon%20C.%20Kone">Doufoungognon C.

Due to pollutants exposure, organisms might modify their thermal niches in order to track the thermal conditions limiting the negative impacts of chemical stressors depending on their mode of action. This study tests the influence of different pollutants, copper, salt, and chloramphenicol, on the thermal preferences of the ciliate Tetrahymena thermophila. Six genotypes were exposed to a gradient of concentrations ranging from 0 to 500mg/L for copper, 0 to 300 mg/l for chloramphenicol, and 0 to 12g/l for salt in synthetic media at eight temperatures ranging from 11 to 39° C. The measured fitness proxies are the maximum growth rate and the 50% growth inhibitory concentration (IC50). The results show that the majority of genotypes are more resistant to chloramphenicol in temperatures below their thermal optimum without pollutants, while they better tolerate other salt and copper in temperatures above their thermal optimum. In addition, generalists reduce their niche width while specialists widen it in chloramphenicol. Overall, results suggest that global warming would have a particularly deleterious effect in the case of chemical pollution. This pollution would induce the full disruption of the thermal habitats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ciliate" title="ciliate">ciliate</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20niche" title=" thermal niche"> thermal niche</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20rate" title=" growth rate"> growth rate</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20stressors" title=" multiple stressors"> multiple stressors</a> </p> <a href="https://publications.waset.org/abstracts/163251/influence-of-chemical-pollution-on-thermal-habitats-of-the-ciliate-tetrahymena-thermophila" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163251.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">90</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">40</span> Use of Chemical Extractions to Estimate the Metals Availability in Bricks Made of Dredged Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fabienne%20Baraud">Fabienne Baraud</a>, <a href="https://publications.waset.org/abstracts/search?q=Lydia%20Leleyter"> Lydia Leleyter</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Poree"> Sandra Poree</a>, <a href="https://publications.waset.org/abstracts/search?q=Melanie%20Lemoine"> Melanie Lemoine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SEDIBRIC (valorization de SEDIments en BRIQues et tuiles) is a French project that aims to replace a part of natural clays with dredged sediments in the preparation of fired bricks in order to propose an alternative solution for the management of harbor dredged sediments. The feasibility of such re-use is explored from a technical, economic, and environmental point of view. The present study focuses on the potential environmental impact of various chemical elements (Al, Ca, Cd, Co, Cr, Cu, Fe, Ni, Mg, Mn, Pb, Ti, and Zn) that are initially present in the dredged sediments. The total content (after acid digestion) and the environmental availability (estimated by single extractions with various extractants) of these elements are determined in the raw sediments and in the obtained fired bricks. The possible influence of some steps of the manufacturing process (sediment pre-treatment, firing) is also explored. The first results show that the pre-treatment step, which uses tap water to desalinate the raw sediment, does not influence the environmental availability of the studied elements. However, the firing process, performed at 900°C, can affect the amount of some elements detected in the bricks, as well as their environmental availability. We note that for Cr, or Ni, the HCl or EDTA availability was increased in the brick (compared to the availability in the raw sediment). For Cd, Cu, Pb, and Zn, the HCl and EDTA availability was reduced in the bricks, meaning that these elements were stabilized within the bricks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bricks" title="bricks">bricks</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20extraction" title=" chemical extraction"> chemical extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a> </p> <a href="https://publications.waset.org/abstracts/132584/use-of-chemical-extractions-to-estimate-the-metals-availability-in-bricks-made-of-dredged-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132584.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">150</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">39</span> Alexandria’s Eastern Entrance: Analysis of Qaitbay Waterfront Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riham%20A.%20Ragheb">Riham A.

It is a favorite location for major tourism initiatives, celebrations and ceremonies. The vitality of any city depends on citizen action to take part in creating the neighborhoods they desire. Waterfront can provide extensive new areas of high quality public open space in parts of the city that are popular venues for social activities and also have the highest land values. Each city must have a character that can be used as a key attraction for the development. The morphology of a waterfront can be identified by both its physical characteristics and the socio-cultural activities that take place in the area. Alexandria has been selected as an area of study because it has a unique character due to its possession of a variety of waterfronts. This paper aims to set some criteria of successful waterfront development and then through these criteria analyzing the development of the Qaitbay waterfront in the eastern harbor in Alexandria, Egypt. Hence, a comprehensive improvement of the waterfront areas is certainly needed to ensure a successful waterfront development radiated the sense of uniformity and coherence. Alexandria can benefit from these criteria to develop its urban waterfront in order to preserve and revitalize its unique waterfront character and achieve mixed uses and tourism development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=place%20making" title="place making">place making</a>, <a href="https://publications.waset.org/abstracts/search?q=Qaitbay" title=" Qaitbay"> Qaitbay</a>, <a href="https://publications.waset.org/abstracts/search?q=responsive%20environment" title=" responsive environment"> responsive environment</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20design" title=" sustainable urban design"> sustainable urban design</a>, <a href="https://publications.waset.org/abstracts/search?q=waterfront%20development" title=" waterfront development"> waterfront development</a> </p> <a href="https://publications.waset.org/abstracts/7590/alexandrias-eastern-entrance-analysis-of-qaitbay-waterfront-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7590.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">236</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">38</span> Effect of Cuminum Cyminum L.

Humans and most domesticated animals harbor S. aureus, and so we may expect staphylococci to be present in food products of animal origin or in those handled directly by humans, unless heat processing is applied to destroy them. Cuminum cyminum L. has been allocated the topic of some recent studies in addition to its well-documented traditional usage for treatment of toothache, dyspepsia, diarrhea, epilepsy and jaundice. The air-dried seed of the plant was completely immersed in water and subjected to hydro distillation for 3 h, using a clevenger-type apparatus. In this study, the effect of Cuminum cyminum L. essential oil (EO) on growth of Staphylococcus aureus in white brined cheese was evaluated. The experiment included different levels of EO (0, 7.5, 15 and 30 mL/ 100 mL milk) to assess their effects on S. aureus count during the manufacture, ripening and storage of Iranian white brined cheese for up to 75 days. The significant (P < 0.05) inhibitory effects of EO (even at its lowest concentration) on this organism were observed. The significant (P < 0.05) inhibitory effect of the EO on S. aureus shown in this study may improve the scope of the EO function in the food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cuminum%20cyminum%20L.%20essential%20oil" title="cuminum cyminum L. essential oil">cuminum cyminum L. essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococcus%20aureus" title=" staphylococcus aureus"> staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20brined%20cheese" title=" white brined cheese"> white brined cheese</a> </p> <a href="https://publications.waset.org/abstracts/23074/effect-of-cuminum-cyminum-l-essential-oil-on-staphylococcus-aureus-during-the-manufacture-ripening-and-storage-of-white-brined-cheese" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23074.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">389</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">37</span> Campylobacteriosis as a Zoonotic Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Jafarzadeh">A.

This is most commonly caused by C. jejuni, It is among the most common bacterial infections of humans, often a foodborne illness. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, mostly including cramps, fever and pain. It is found in cattle, swine, and birds, where it is non-pathogenic. But the illness can also be caused by C. coli (also found in cattle, swine, and birds) C. upsaliensis (found in cats and dogs) and C. lari (present in seabirds in particular). Infection with a Campylobacter species is one of the most common causes of human bacterial gastroenteritis. For instance, an estimated 2 million cases of Campylobacter enteritis occur annually in the U.S., accounting for 5-7% of cases of gastroenteritis. Furthermore, in the United Kingdom during 2000 Campylobacter jejuni was involved in 77.3% in all cases of foodborne illness. 15 out of every 100,000 people are diagnosed with campylobacteriosis every year, and with many cases going unreported, up to 0.5% of the general population may unknowingly harbor Campylobacter in their gut annually. A large animal reservoir is present as well, with up to 100% of poultry, including chickens, turkeys, and waterfowl, having asymptomatic infections in their intestinal tracts. An infected chicken may contain up to 109 bacteria per 25 grams, and due to the installations, the bacteria is rapidly spread to other chicken. This vastly exceeds the infectious dose of 1000-10,000 bacteria for humans. In this article this disease is fully discussed in human and animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=campylobacteriosis" title="campylobacteriosis">campylobacteriosis</a>, <a href="https://publications.waset.org/abstracts/search?q=human" title=" human"> human</a>, <a href="https://publications.waset.org/abstracts/search?q=animal" title=" animal"> animal</a>, <a href="https://publications.waset.org/abstracts/search?q=zoonosis" title=" zoonosis"> zoonosis</a> </p> <a href="https://publications.waset.org/abstracts/35731/campylobacteriosis-as-a-zoonotic-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35731.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">514</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">36</span> Parental Perceptions and Practices toward Childhood Asthma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20K.%20Abu-Shaheen">Amani K.

Objective: To identify the prevalence of asthma and to investigate the perceptions and practices of parents toward asthma and its management in Saudi children. Methods: A two-stage cross-sectional survey of 2000 parents of children aged 3–15 years from schools located in all five districts of Riyadh province located in central Saudi Arabia, was conducted. Data collection was accomplished using a self-administered questionnaire based on information obtained from the literature. Results: Of 1450 children whose parents participated in the study, 600 had asthma, dyspnea, or chest allergy. The overall number of children with parental reports of ever having been diagnosed with asthma was 478 (32.9%). The majority of parents (321, 53.5%) believed that asthma was a hereditary disease. Of these parents, 361 (60.3%) were concerned about side effects of inhaled steroids, and 192 (32%) about development of dependency on asthma medications. Three hundred sixty seven (61.2%) parents reported that they could treat the asthma attack at home and almost 76% of parents went to pediatric emergency department during asthma attack. Conclusions: In this study, the overall prevalence of children whose parents reported that they were diagnosed with asthma was high (32.9%). Furthermore, parents of children with asthma had misperceptions regarding asthma and exhibited ineffective practices in its management. To improve asthma care and compliance, adequate education should be provided to parents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asthma" title="asthma">asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=parents" title=" parents"> parents</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a> </p> <a href="https://publications.waset.org/abstracts/45901/parental-perceptions-and-practices-toward-childhood-asthma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45901.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">274</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">35</span> Isolation and Characterization of Endophytic Bacteria Associated with Root-Nodules of Medicago sativa in Al-Ahasa Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Y.%20Z.%20Khalifa">Ashraf Y.

Soil bacteria exist in root or root-nodules of Medicago sativa in either symbiotic relationships or in associations. The aim of the present study was to isolate and characterize endophytic bacteria that live in association with non-nodulated roots of Medicago sativa growing in Al-Ahsaa region, Saudia Arabia. Several bacterial strains were isolated from sterilized roots of Medicago sativa. Strains were characterized using 16S rRNA gene sequences, phylogenetic relationships analysis, morphological and biochemical characteristics. The strains utilized 50% (10 out of 20) of the different chemical substrates contained in the API20E strip. In general, many strains had the ability to ferment/oxidise all the carbohydrate tested except for rhamnose and the polyol carbohydrate, inositol. Comparative sequence analysis of the 16S rDNA gene indicated that the strains were closely related to the genus Bacillus. Furthermore, the growth parameters of Vigna sinensis were enhanced upon single-inoculation of the isolated strains, compared to the uninoculated control plants. The results highlighted that the root-nodules of Medicago sativa harbor non-nodulating bacterial strains that could have significant agricultural applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Medicago%20sativa" title="Medicago sativa">Medicago sativa</a>, <a href="https://publications.waset.org/abstracts/search?q=endophytic%20bacteria" title=" endophytic bacteria"> endophytic bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=Pisum%20sativum" title=" Pisum sativum"> Pisum sativum</a>, <a href="https://publications.waset.org/abstracts/search?q=Vigna%20sinensis" title=" Vigna sinensis"> Vigna sinensis</a> </p> <a href="https://publications.waset.org/abstracts/7225/isolation-and-characterization-of-endophytic-bacteria-associated-with-root-nodules-of-medicago-sativa-in-al-ahasa-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7225.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">377</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">34</span> Durability of a Cementitious Matrix Based on Treated Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahfoud%20Benzerzour">Mahfoud Benzerzour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouhamadou%20Amar"> Mouhamadou Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amine%20Safhi"> Amine Safhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor-Edine%20Abriak"> Nor-Edine Abriak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Significant volumes of sediment are annually dredged in France and all over the world. These materials may, in fact, be used beneficially as supplementary cementitious material. This paper studies the durability of a new cement matrix based on marine dredged sediment of Dunkirk-Harbor (north of France). Several techniques are used to characterize the raw sediment such as physical properties, chemical analyses, and mineralogy. The XRD analysis revealed quartz, calcite, kaolinite as main mineral phases. In order to eliminate organic matter and activate some of those minerals, the sediment is calcined at a temperature of 850°C for 1h. Moreover, four blended mortars were formulated by mixing a portland cement (CEM I 52,5 N) and the calcined sediment as partial cement substitute (0%, 10%, 20% and 30%). Reference mortars, based on the blended cement, were then prepared. This re-use cannot be substantiating and efficient without a durability study. In this purpose, the following tests, mercury porosity, accessible water porosity, chloride permeability, freezing and thawing, external sulfate attack, alkali aggregates reaction, compressive and bending strength tests were conducted on those mortars. The results of most of those tests evidenced the fact that the mortar that contains 10% of the treated sediment is efficient and durable as the reference mortar itself. That would infer that the presence of these calcined sediment improves mortar general behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sediment" title="sediment">sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=calcination" title=" calcination"> calcination</a>, <a href="https://publications.waset.org/abstracts/search?q=substitution" title=" substitution"> substitution</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a> </p> <a href="https://publications.waset.org/abstracts/62380/durability-of-a-cementitious-matrix-based-on-treated-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62380.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">257</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">33</span> Jeddah’s Hydraulic Protection Systems and the Management of Flood: An Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Ameur">Faouzi Ameur</a>, <a href="https://publications.waset.org/abstracts/search?q=Atef%20Belhaj%20Ali"> Atef Belhaj Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Located in the South-west of Saudi Arabia, Jeddah is more than a harbor. It is a big city of the Red Sea and the second town of Saudi Arabia, after Riyadh the capital. Jeddah profits from several economic assets due especially to its transit position towards the high sacred places of Islam like Mecca and Medina. During summer, this metropolis is transformed into a political capital and a tourist resort for foreigners and Saudis alike. The city of Jeddah was affected by serious sudden floods; two great ones took place in 2009, and in 2011. The human and material tools were considerable, since these events caused the death to hundreds of people, damaged thousands of buildings built on basins slopes, which, however had the authorizations necessary. To cope with these natural disasters, several urban hydraulic measures were undertaken like building dams and canals to collect surface waters. These urban measures aimed at the protection of inhabitants and belongings against the risks of floods as well as the interception and the drainage of streams. Although these protection measures are important, expensive, and effective, they are no longer enough or effective to cope with the evolution of the natural disasters that the city of Jeddah is constantly exposed to. These protective hydraulic measures did not make it possible to reach risk zero situations. They transferred the damages towards other zones. This paper purports to study the protection network systems in Jeddah and to understand their various impacts during floods on the city and on its inhabitants. <p
