To test the suggested algorithm, ten homologous genes are selected and collected from National Center for Biotechnology Information (NCBI) databanks (i.e., 16S, 18S, 28S, Cox 1, ITS1, ITS2, ETS, ATPB, Hsp90, and STN). The data are divided into three categories: 50 taxa, 100 taxa and 500 taxa.

The basic problem in genome rearrangements is to compute the edit distance, i.e., the minimum number of operations needed to transform one genome into another. Unfortunately, unsigned genome rearrangement problem is NP-hard. In this study an improved ant colony optimization algorithm to approximate the edit distance is proposed. The main idea is to convert the unsigned permutation to signed permutation and evaluate the ants by using Kaplan algorithm. Two new operations are added to the standard ant colony algorithm: Replacing the worst ants by re-sampling the ants from a new probability distribution and applying the crossover operations on the best ants. The proposed algorithm is tested and compared with the improved breakpoint reversal sort algorithm by using three datasets. The results indicate that the proposed algorithm achieves better accuracy ratio than the previous methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ant%20colony%20algorithm" title="ant colony algorithm">ant colony algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=edit%20distance" title=" edit distance"> edit distance</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%0D%0Abreakpoint" title=" genome breakpoint"> genome breakpoint</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20rearrangement" title=" genome rearrangement"> genome rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=reversal%20sort" title=" reversal sort"> reversal sort</a> </p> <a href="https://publications.waset.org/abstracts/5601/an-improved-ant-colony-algorithm-for-genome-rearrangements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5601.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">344</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">80</span> A Comparative Study of Microstructure, Thermal and Mechanical Properties of A359 Composites Reinforced with SiC, Si3N4 and AlN Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essam%20Shalaby">Essam Shalaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Churyumov"> Alexander Churyumov</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Abou%20El-Khair"> Malak Abou El-Khair</a>, <a href="https://publications.waset.org/abstracts/search?q=Atef%20Daoud"> Atef Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A comparative study of the thermal and mechanical behavior of squeezed A359 composites containing 5, 10 and 15 wt.% SiC, (SiC+ Si3N4) and AlN particulates was investigated. Stir followed by squeeze casting techniques are used to produce A359 composites. It was noticed that, A359/AlN composites have high thermal conductivity as compared to A359 alloy and even to A359/SiC or A359/(SiC+Si3N4) composites. Microstructures of the composites have shown homogeneous and even distribution of reinforcements within the matrix. Interfacial reactions between particles and matrix were investigated using X-ray diffraction and energy dispersive X-ray analysis. The presence of particles led not only to increase peak hardness of the composites but also to accelerate the aging kinetics. As compared with A359 matrix alloy, compression test of the composites has exhibited a significant increase in the yield and the ultimate compressive strengths with a relative reduction in the failure strain. Those light weight composites have a high potential to be used for automotive and aerospace applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal-matrix%20composite" title="metal-matrix composite">metal-matrix composite</a>, <a href="https://publications.waset.org/abstracts/search?q=squeeze" title=" squeeze"> squeeze</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20properties" title=" compressive properties"> compressive properties</a> </p> <a href="https://publications.waset.org/abstracts/66981/a-comparative-study-of-microstructure-thermal-and-mechanical-properties-of-a359-composites-reinforced-with-sic-si3n4-and-aln-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66981.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">381</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">79</span> Coating Solutions: Study of Rheology Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Abid">D.

Oto-nephrotxicity is an important and dose - limiting side effect of cis - platin therapy. Nowadays, more attention had been paid to oto-toxicity caused with cis-platin. Aim of the Work: This study was designed to investigate the potential protective effect of Whey protein (WP) against cis-platin induced ototoxicity compared to the effect of N-acetylcysteine (NAC) in rats. Methodology: Male albino rats were randomly divided into 6 groups: untreated rats (control), rats orally treated with whey protein (1g/kg b.w/day) for seven executive days, rats treated orally with N-acetylcysteine (500 mg/kgb.w /day) for seven executive days, rates intoxicated intraperitoneal (ip) with cis- platin (10 mg/kgb.w. once), rats treated with whey protein (1g/kgb.w./day) for seven executive days) followed by one injection (ip) of cis-platin(10 mg/kg b.w.) one hour after the last oral administration of whey protein, rats treated with N- acetylcysteine (for seven executive days followed by one injection (ip) of cis-platin (10 mg/kgb.w) one hour after the last oral administration of N-acetylcysteine. The organ of Corti, the stria vascularis and spiral ganglia were visualized by light microscopy at different magnifications. Results: Cis-platin intoxicated animals showed a significant decrease in serum level of total antioxidant capacity (TAC),with inhibition in the activity of serum glutathione-s transferase(GST) and paraoxonnase-1 (PON-1) in comparison with control. Group treated with either NAC or WP with cis-platin showed significant elevation in the activity of both GST & PON-1 with increased serum level of TAC when compared with cis-platin intoxicated rats. Animals treated with NAC or WP with cis-platin compared to those treated with cis-platin alone showed marked degree of improvement towards control rats as there was significant drop in the serum level of cortecosterone, nitric oxide (NO), and melandialdehyde (MDA).Histopathologic, in NAC pretreated group there was no changes in stria vascularis or spiral ganglia. In group pretreated with WP, there was no histopathologic alteration detected in the organ of Corti and Reissers membrane but oedema and haemorrhage were founded in the stria vascularis in small focal manner. Conclusion: Our finding showed that Whey protein is a natural dietary supplement product proved its ability of protection of anti-oxidant system and the cochlea against cis-platin induced ototoxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-oxidant" title="anti-oxidant">anti-oxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=cis-platin" title=" cis-platin"> cis-platin</a>, <a href="https://publications.waset.org/abstracts/search?q=N-acetylcysteine" title=" N-acetylcysteine"> N-acetylcysteine</a>, <a href="https://publications.waset.org/abstracts/search?q=ototoxicity" title=" ototoxicity"> ototoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=whey%20protein" title=" whey protein "> whey protein </a> </p> <a href="https://publications.waset.org/abstracts/29781/whey-protein-a-noval-protective-agent-against-oto-toxicity-induced-by-cis-platin-in-male-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29781.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">523</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">70</span> Exploring Cybersecurity and Phishing Attacks within Healthcare Institutions in Saudi Arabia: A Narrative Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebtesam%20Shadadi">Ebtesam Shadadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Ibrahim"> Rasha Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Ghadafi"> Essam Ghadafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phishing poses a significant threat as a cybercrime by tricking end users into revealing their confidential and sensitive information.

It causes soft bones, which can become bowed or curved, this bending and curvature is evident in the age of Walking. The most common cause of rickets is dietary deficiency of vitamin D or Lack of exposure to sunlight or both together. The link between vitamin D and rickets has been known for many years and is well understood by doctors and scientists. If a child does not get enough of the vitamin D, the bones cannot form hard outer shells. This is why they become soft and weak. This study was conducted on children who reviewed by our medical clinic between the years 2011-2013. The study included 400 children, aged between one and six years. 11 children had clear clinical manifestations of rickets of varying degrees and all of them due to lack of vitamin D except for one case of rickets resistant to vitamin D. 389 cases ranged between natural and deficiency in vitamin D without clinical manifestations of Rickets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rickts" title="rickts">rickts</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20metabolic%20diseases" title=" bone metabolic diseases"> bone metabolic diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D" title=" vitamin D"> vitamin D</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a> </p> <a href="https://publications.waset.org/abstracts/39361/vitamin-d-and-prevention-of-rickets-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39361.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">415</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">67</span> Simulation and Experimental of Solid Mixing of Free Flowing Material Using Solid Works in V-Blender</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Bouhaouche">Amina Bouhaouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Kaoua"> Zineb Kaoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Lila%20Lahreche"> Lila Lahreche</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ali%20Kaoua"> Sid Ali Kaoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Daoud"> Kamel Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to present a novel approach for analyzing the solid dispersion and mixing performance by a numerical simulation method using solid works software of a monodisperse particles for a large span of time reached 20 minutes.

The aim of this paper was to review clinical heterogeneity; radiographic abnormalities and genetic etiology in Klippel-Feil Syndrome. We insist in comprehensive evaluation and delineation of diagnostic and prognostic classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Klippel%E2%80%93Feil%20anomaly" title="Klippel–Feil anomaly">Klippel–Feil anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20heterogeneity" title=" clinical heterogeneity"> clinical heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=radiographic%20abnormalities" title=" radiographic abnormalities"> radiographic abnormalities</a> </p> <a href="https://publications.waset.org/abstracts/18316/klippel-feil-syndrome-a-case-report-and-review-of-literature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18316.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">484</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">63</span> Software Obsolescence Drivers in Aerospace: An Industry Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Gonz%C3%A1lez%20Mu%C3%B1oz">Raúl González Muñoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Shehab"> Essam Shehab</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Weinitzke"> Martin Weinitzke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Fowler"> Chris Fowler</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Baguley"> Paul Baguley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Software applications have become crucial for the aerospace industry, providing a wide range of functionalities and capabilities. However, due to the considerable time difference between aircraft and software life cycles, obsolescence has turned into a major challenge for industry in last decades. This paper aims to provide a view on the different causes of software obsolescence within aerospace industry, as well as a perception on the importance of each of them. The key research question addressed is what drives software obsolescence in the aerospace industry, managing large software application portfolios. This question has been addressed by conducting firstly an in depth review of current literature and secondly by arranging an industry workshop with professionals from aerospace and consulting companies. The result is a set of drivers of software obsolescence, distributed among three different environments and several domains. By incorporating monitoring methodologies to assess those software obsolescence drivers, benefits in maintenance efforts and operations disruption avoidance are expected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerospace%20industry" title="aerospace industry">aerospace industry</a>, <a href="https://publications.waset.org/abstracts/search?q=obsolescence%20drivers" title=" obsolescence drivers"> obsolescence drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20lifecycle" title=" software lifecycle"> software lifecycle</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20obsolescence" title=" software obsolescence"> software obsolescence</a> </p> <a href="https://publications.waset.org/abstracts/72049/software-obsolescence-drivers-in-aerospace-an-industry-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72049.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">411</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">62</span> Study of Changes in the Pulsation Period of Six Cepheid Variables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdel%20Sabour">Mohamed Abdel Sabour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nouh"> Mohamed Nouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20Stevans"> Ian Stevans</a>, <a href="https://publications.waset.org/abstracts/search?q=Essam%20Elkholy"> Essam Elkholy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the period change of six Cepheids using 19376 accurate flux observations of the Solar Mass Ejection Imager (SMEI) onboard the Coriolis spacecraft. All observations for the six Cepheids have been derived as templates for each star, independent of the specific sites utilized to establish and update the O-C values. Sometimes, sinusoidal patterns are superimposed on the star's O-C changes, which cannot be regarded as random fluctuations in the pulsation period. Random period changes were detected and computed using Eddington's and Plakidis's approaches. A comparison of the observed and predicted period change reveals a good agreement with some published models and a very substantial divergence with others. Between the reported period change and that estimated by the current technique, a linear fit with a correlation coefficient of 90.08 percent was obtained. The temporal rate of period change in Cepheid stars might be connected to how well these stars' mass losses are known today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cepheids" title="cepheids">cepheids</a>, <a href="https://publications.waset.org/abstracts/search?q=period%20change" title=" period change"> period change</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=O-C%20changes" title=" O-C changes"> O-C changes</a>, <a href="https://publications.waset.org/abstracts/search?q=period%20change" title=" period change"> period change</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20loss" title=" mass loss"> mass loss</a>, <a href="https://publications.waset.org/abstracts/search?q=O-C" title=" O-C"> O-C</a> </p> <a href="https://publications.waset.org/abstracts/187496/study-of-changes-in-the-pulsation-period-of-six-cepheid-variables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187496.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">41</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">61</span> Evaluation of the Behavior of Micronutrients in Salty Soils of Low Cheliff</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Degui">N.

The chemical fractionation method was used for the speciation study (different forms) of micronutrients in these soils. The results show that total form quantities of cations are height than norms in agricultural soils, thus the quantities of anion are lows. At the other hand, the quantities of available forms are lows. Statistical analysis reveals that cationic micronutrients localize preferentially in the coarse fraction of the soil in salty conditions and that sodicity causes a decrease in the iron reserve in the soil. The pH range ‘7.49 - 8.76’ represents a constraint for the complexation of micronutrients by organic matter. The study concluded that quantities of total and available forms of micronutrients in salty soils are influenced by soil properties such as: pH, electrical conductivity and exchangeable sodium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20fractionation" title="chemical fractionation">chemical fractionation</a>, <a href="https://publications.waset.org/abstracts/search?q=micronutrients" title=" micronutrients"> micronutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=salty%20soils" title=" salty soils"> salty soils</a>, <a href="https://publications.waset.org/abstracts/search?q=speciation" title=" speciation"> speciation</a> </p> <a href="https://publications.waset.org/abstracts/92470/evaluation-of-the-behavior-of-micronutrients-in-salty-soils-of-low-cheliff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92470.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Investigation of the Effect of Grid Size on External Store Separation Trajectory Using CFD</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20A.%20Osman">Alaa A.

This novel is a postmodernist exploration of the grand-narrative myth The Odyssey (800 BC) by Homer, who portrayed the heroic warrior and the faithful wife as the epitome of perfect male and female models _examples whom all must follow and mimic. In Atwood's narrative, the same two hero models are the two great tricksters who are willing to perform any sort of obnoxious act for achieving their goals. This research tries to examine how Atwood tried to synthesize the change in character’s narratives leading to the humanization of the perfect hero and the ideal wife. The researcher has used a multidisciplinary approach where the feminist, revisionist and deconstructive theories were implemented to identify and find out the new interpretations of the myths that center the experiences and perspectives of women. Research findings are that revisionist approach was applied through giving an opportunity to the victimized and the voiceless to speak out and retaliate against their prosecutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=margret%20atwood" title="margret atwood">margret atwood</a>, <a href="https://publications.waset.org/abstracts/search?q=patriarchal" title=" patriarchal"> patriarchal</a>, <a href="https://publications.waset.org/abstracts/search?q=penelopiad" title=" penelopiad"> penelopiad</a>, <a href="https://publications.waset.org/abstracts/search?q=revisionism" title=" revisionism"> revisionism</a> </p> <a href="https://publications.waset.org/abstracts/168755/revisionism-in-literature-deconstructing-patriarchal-ideals-in-margaret-atwoods-the-penelopiad" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168755.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">83</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> Some Probiotic Traits of Lactobacillus Strains Isolated from Pollen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hani%20Belhadj">Hani Belhadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Daoud%20Harzallah"> Daoud Harzallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Seddik%20Khennouf"> Seddik Khennouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Saliha%20Dahamna"> Saliha Dahamna</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouloud%20Ghadbane"> Mouloud Ghadbane </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Lactobacillus strains isolated from pollen were identiﬁed by means of phenotypic and genotypic methods, At pH 2, most strains proved to be acid resistants, with losses in cell viability ranging from 0.77 to 4.04 Log orders. In addition, at pH 3 all strains could grew and resist the acidic conditions, with losses in cell viability ranging from 0.40 to 3.61 Log orders. It seems that, 0.3% and 0.5% of bile salts does not affect greatly the survival of most strains, excluding Lactobacillus sp. BH1398. Survival ranged from 81.0±3.5 to 93.5±3.9%. In contrast, in the presence of 1.0% bile salts, survival of five strains was decreased by more than 50%. Lactobacillus fermentum BH1509 was considered the most tolerant strain (77.5% for 1% bile) followed by Lactobacillus plantarum BH1541 (59.9% for 1% bile). Furthermore, all strains were resistant to colistine, clindamycine, chloramphenicol, and ciprofloxacine, but most of the strains were susceptible to Peniciline, Oxacillin, Oxytetracyclin, and Amoxicillin. Functionally interesting Lactobacillus isolates may be used in the future as probiotic cultures for manufacturing fermented foods and as bioactive delivery systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotics" title="probiotics">probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=lactobacillus" title=" lactobacillus"> lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=pollen" title=" pollen"> pollen</a>, <a href="https://publications.waset.org/abstracts/search?q=bile" title=" bile"> bile</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20tolerance" title=" acid tolerance"> acid tolerance</a> </p> <a href="https://publications.waset.org/abstracts/14064/some-probiotic-traits-of-lactobacillus-strains-isolated-from-pollen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14064.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">420</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> The Effect of Street Dust on Urban Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Turki%20M.%20Habeebullah">Turki M.

It does not remain deposited in a place for long, as it is easily resuspended back into the atmosphere. Street dust is a complex mixture derived from different sources: Deposited dust, traffic, tire, and brake wear, construction and demolition processes. The present study aims to evaluate the elementals ”iron, calcium, lead, cadmium, nickel, silicon, and selenium” and microbial “bacteria and fungi” contents associated street dust at the holy mosque areas. The street dust was collected by sweeping an arera~1m2 along the both sides of the road. The particles with diameter ≤ 1.7 µm constitued the highest percentages of the total particulate ≤45 µm. Moreover, The crustal species: iron and calcium were found in the highest concentrations, and proof that demolition and constricution were the main source of street dust.

Alternative heat treatment processes, such as contact heating, have been developed to improve the efficiency of this process. However, contact heating of the steel sheets often results in cracking within the Al-Si-coated layer. Therefore, this paper will address the development of alternative coating compositions based on Al-Si-X, suitable for contact heating. For this purpose, robot-assisted thermal arc spray was applied to coat the high-strength steel sheets. This ensured high reproducibility as well as effectiveness. The influence of the coating parameters and the variation of the nozzle geometry on the microstructure of the developed coatings will be discussed.

Central to maximizing growth are critical light-related factors, including quantity, quality, and geometric distribution of intercepted radiation. This becomes particularly crucial in regions like the Middle East, characterized by high solar radiation and dusty atmospheric conditions. Existing greenhouse technologies often rely on additional expensive equipment to manage light conditions effectively. In this study, we propose a distinct approach employing functional coatings to mitigate dust and block UV and IR radiation, thereby conserving energy and enhancing productivity. By combining UV-IR reflective coatings with dust mitigation strategies, we aim to address both environmental challenges and energy consumption issues faced by greenhouse agriculture in Saudi Arabia.
