We tested the prepared NiFe2O4(NPS)by monitoring the degradation of Rose Bengal (RB) dye in an aqueous solution under direct sunlight irradiation. The effects of catalyst dosage and dye concentration were also considered for the effective degradation of RB dye. The optimum catalyst dosage and concentration of dye were found to be 1 g/L and 10 μM, respectively. A maximum of 80% photocatalytic degradation efficiency (DE%) was achieved at 120 min of direct sunlight irradiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rose%20Bengal" title="Rose Bengal">Rose Bengal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nickelate" title=" Nickelate"> Nickelate</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=irradiation" title=" irradiation"> irradiation</a> </p> <a href="https://publications.waset.org/abstracts/142028/degradation-of-rose-bengal-by-uv-in-the-presence-of-nife2o4-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142028.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">213</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">6</span> Surface Hole Defect Detection of Rolled Sheets Based on Pixel Classification Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Taleb">Samira Taleb</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakina%20Aoun"> Sakina Aoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Slimane%20Ziani"> Slimane Ziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoheir%20Mentouri"> Zoheir Mentouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Boudiaf"> Adel Boudiaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rolling is a pressure treatment technique that modifies the shape of steel ingots or billets between rotating rollers. During this process, defects may form on the surface of the rolled sheets and are likely to affect the performance and quality of the finished product. In our study, we developed a method for detecting surface hole defects using a pixel classification approach. This work includes several steps. First, we performed image preprocessing to delimit areas with and without hole defects on the sheet image. Then, we developed the histograms of each area to generate the gray level membership intervals of the pixels that characterize each area. As we noticed an intersection between the characteristics of the gray level intervals of the images of the two areas, we finally performed a learning step based on a series of detection tests to refine the membership intervals of each area, and to choose the defect detection criterion in order to optimize the recognition of the surface hole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification" title="classification">classification</a>, <a href="https://publications.waset.org/abstracts/search?q=defect" title=" defect"> defect</a>, <a href="https://publications.waset.org/abstracts/search?q=surface" title=" surface"> surface</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=hole" title=" hole"> hole</a> </p> <a href="https://publications.waset.org/abstracts/193037/surface-hole-defect-detection-of-rolled-sheets-based-on-pixel-classification-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193037.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">15</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">5</span> Efficacy of Microbial Metabolites Obtained from Saccharomyces cerevisiae as Supplement for Quality Milk Production in Dairy Cows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20ur%20Rahman">Sajjad ur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Azam"> Mariam Azam</a>, <a href="https://publications.waset.org/abstracts/search?q=Mukarram%20Bashir"> Mukarram Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Seemal%20Javaid"> Seemal Javaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoun%20Muhammad"> Aoun Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tahir"> Muhammad Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawad"> Jawad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannan%20Khan"> Hannan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zohaib"> Muhammad Zohaib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Partially fermented soya hulls and wheat bran through Saccharomyces cerevisiae (DL-22 S/N) substantiated as a natural source for quality milk production.

In this concept, an organic substance present in many industrial effluents was chosen: naproxen ((S)-6-methoxy-α-methyl-2-naphthaleneacetic acid or 2-(6-methoxynaphthalenyl) propanoic), a non-steroidal anti-inflammatory drug. The main objective of this study is to degrade naproxen by an iron and nickel catalyst, the degradation of this organic pollutant by nickel ferrite has been studied in a heterogeneous aqueous medium, with the study of the various factors influencing photocatalysis such as the concentration of matter and the acidity of the medium. The photocatalytic activity was followed by HPLC-UV andUV-Vis spectroscopy. A first-order kinetic model appropriately fitted the experimental data. The degradation of naproxen was also studied in the presence of H₂O₂ as well as in an aqueous solution. The new hetero-system NiFe₂O₄/oxalic acid is also discussed. The fastest naproxen degradation was obtained with NiFe₂O₄/H₂O₂. In a first-place, we detailed the characteristics of the material NiFe₂O₄, which was synthesized by the sol-gel methods, using various analytical techniques: visible UV spectrophotometry, X-ray diffraction, FTIR, cyclic voltammetry, luminescent discharge optical emission spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=naproxen" title="naproxen">naproxen</a>, <a href="https://publications.waset.org/abstracts/search?q=nickelate" title=" nickelate"> nickelate</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=oxalic%20acid" title=" oxalic acid"> oxalic acid</a> </p> <a href="https://publications.waset.org/abstracts/141299/photocatalytic-degradation-of-naproxen-in-water-under-solar-irradiation-over-nife2o4-nanoparticle-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141299.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">209</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">3</span> Efficiency of Microbial Metabolites on Quality Milk Production in Nili Ravi Breed of Buffalos</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Ur%20Rahman">Sajjad Ur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tahir"> Muhammad Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mukarram%20Bashir"> Mukarram Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawad"> Jawad</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoun%20Muhammad"> Aoun Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zohaib"> Muhammad Zohaib</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannan%20Khan"> Hannan Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Seemal%20Javaid"> Seemal Javaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Azam"> Mariam Azam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The efficiency of natural metabolites obtained from partially fermented soya hulls and wheat bran using Saccharomyces cerevisiae (DL-22 S/N) ensures a potential impact on the total milk yield and quality of milk production.

At the same time, the incidence rate of mastitis recorded for the animals under trial was reduced to half, and improved non specific immunity was reported. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microbial%20metabolites" title="microbial metabolites">microbial metabolites</a>, <a href="https://publications.waset.org/abstracts/search?q=post-biotics" title=" post-biotics"> post-biotics</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20supplements" title=" animal supplements"> animal supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20nutrition" title=" animal nutrition"> animal nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=proteins" title=" proteins"> proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20production" title=" animal production"> animal production</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/164404/efficiency-of-natural-metabolites-on-quality-milk-production-in-mixed-breed-cows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164404.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> An Extended Domain-Specific Modeling Language for Marine Observatory Relying on Enterprise Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charbel%20Aoun">Charbel Aoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Loic%20Lagadec"> Loic Lagadec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Sensor Network (SN) is considered as an operation of two phases: (1) the observation/measuring, which means the accumulation of the gathered data at each sensor node; (2) transferring the collected data to some processing center (e.g., Fusion Servers) within the SN. Therefore, an underwater sensor network can be defined as a sensor network deployed underwater that monitors underwater activity. The deployed sensors, such as Hydrophones, are responsible for registering underwater activity and transferring it to more advanced components. The process of data exchange between the aforementioned components perfectly defines the Marine Observatory (MO) concept which provides information on ocean state, phenomena and processes. The first step towards the implementation of this concept is defining the environmental constraints and the required tools and components (Marine Cables, Smart Sensors, Data Fusion Server, etc). The logical and physical components that are used in these observatories perform some critical functions such as the localization of underwater moving objects. These functions can be orchestrated with other services (e.g. military or civilian reaction). In this paper, we present an extension to our MO meta-model that is used to generate a design tool (ArchiMO). We propose new constraints to be taken into consideration at design time. We illustrate our proposal with an example from the MO domain. Additionally, we generate the corresponding simulation code using our self-developed domain-specific model compiler. On the one hand, this illustrates our approach in relying on Enterprise Architecture (EA) framework that respects: multiple views, perspectives of stakeholders, and domain specificity. On the other hand, it helps reducing both complexity and time spent in design activity, while preventing from design modeling errors during porting this activity in the MO domain. As conclusion, this work aims to demonstrate that we can improve the design activity of complex system based on the use of MDE technologies and a domain-specific modeling language with the associated tooling. The major improvement is to provide an early validation step via models and simulation approach to consolidate the system design. <p class="card-text"><strong>Keywords:</strong> <a
