The result proved that most of the low-budget film productions find the cast by asking from the crew’s friends or friend of friend. Therefore, finding the cast in low-budget film productions normally has only few people shown up for the auditions and sometimes either none of them has acting knowledge or their appearances do not match the character. However, since most of the low-budget film productions do not have much ability to find members of the cast, thus some of them still will be selected. On the other hand, most of the high-budget film productions use modeling companies to find the cast for them. However, most of modeling agencies in Thailand seek and select their cast members from the cast’s appearances or talents rather than the knowledge of acting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=casting%20for%20film" title="casting for film">casting for film</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20business" title=" modeling business"> modeling business</a>, <a href="https://publications.waset.org/abstracts/search?q=acting" title=" acting"> acting</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=performing%20arts" title=" performing arts"> performing arts</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20business" title=" film business"> film business</a> </p> <a href="https://publications.waset.org/abstracts/12956/analysis-of-casting-call-process-in-thai-film-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12956.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">424</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">1478</span> Fundamental Research Dissension between Hot and Cold Chamber High Pressure Die Casting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahil%20Kumar">Sahil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Surinder%20Pal"> Surinder Pal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Kapoor"> Rahul Kapoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is focused on to define the basic difference between hot and cold chamber high pressure die casting process which is not fully defined in a research before paper which we have studied. The pressure die casting is basically defined into two types (1) Hot chamber Die Casting (2) Cold chamber Die Casting. Cold chamber die casting is used for casting alloys that require high pressure and have a high melting temperature, such as brass, aluminum, magnesium, copper based alloys and other high melting point nonferrous alloys. Hot chamber die casting is suitable for casting zinc, tin, lead, and low melting point alloys. In hot chamber die casting machine, the molten metal is an integral pan of the machine. It mainly consists of hot chamber and gooseneck type metal container made of cast iron. This machine is mainly used for low melting alloys and alloys of metals like zinc, lead etc. Metals and alloys having a high melting point and those which are having an affinity for iron cannot be cast by this machine, which could otherwise attack the shot sleeve and damage the machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20chamber%20die%20casting" title="hot chamber die casting">hot chamber die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20chamber%20die%20casting" title=" cold chamber die casting"> cold chamber die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=metals%20and%20alloys" title=" metals and alloys"> metals and alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=casting%20technology" title=" casting technology"> casting technology</a> </p> <a href="https://publications.waset.org/abstracts/25342/fundamental-research-dissension-between-hot-and-cold-chamber-high-pressure-die-casting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25342.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">618</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">1477</span> Nano-emulsion/Nano-suspension as Precursors for Oral Dissolvable Film to Enhance Bioavalabilty for Poor-water Solubility Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Yang">Yuan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Mickey%20Lam"> Mickey Lam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oral dissolvable films have been considered as a unique alternative approach to conventional oral dosage forms. The films could be administrated via the gastrointestinal tract as conventional dosages or through sublingual/buccal mucosa membranes, which could enhance drug bioavailability by avoiding the first-pass effect and improving permeability due to high blood flow and lymphatic circulation. This work has described a state-of-art technic using nano-emulsion/nano-suspension as a precursor for the film to enhance the bioavailability of BCS class II drugs. The drug molecules are consequentially processed through the emulsification, gelation, and film-casting processes. The gelation process is critical to stabilizing the nano-emulsion for the film-casting as well as controlling the drug release process. Furthermore, the size of the nanoparticle on the film has a strong correlation with the size of the micelles in the precursor and the condition of the gelation process. It has been discovered that nanoparticle from 200 nm to 300 nm has shown the highest permeability for sublingual administration. In one example shown in work, the bioavailability of a low solubilize drug has been increased from 10% to 24% via sublingual administration of the film. The increasing of the bioavailability was thought to be associated with the enhancement of the diffusion process of the drug in the saliva layer above the mucosa membrane and the fact that the presents of the emulsifier help lose the rigid junction of the mucosa cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20dissolvable%20film" title="oral dissolvable film">oral dissolvable film</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-suspension" title=" nano-suspension"> nano-suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-emulsion" title=" nano-emulsion"> nano-emulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title=" bioavailability"> bioavailability</a> </p> <a href="https://publications.waset.org/abstracts/142588/nano-emulsionnano-suspension-as-precursors-for-oral-dissolvable-film-to-enhance-bioavalabilty-for-poor-water-solubility-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142588.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">183</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">1476</span> Preparation and Analysis of Chitosan-Honey Films for Wound Dressing Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Sasikala">L.

Natural materials like chitosan, herbs, and honey have number of active materials present in them to accelerate wound healing and to arrest wound in infections. Hence with the advantages of biomaterials, a film was prepared using chitosan and honey. There are a lot of practical considerations with respect to honey. Honey exerts many beneficial actions on the wound surface only when it remains. The attempts to hold honey on the surface of the wound remain a question because honey becomes a very runny liquid when it comes to body temperature. Hence, this research was focused on development of a new form of wound dressing, by holding honey on the wound surface in different form and also which has a combined effect of manuka (Leptospermum scoparium) honey and chitosan. Chitosan-honey film was prepared using casting technique. Films were prepared in different variations; with acetic acid and with lactic acid; with and without honey. In summary, the film produced from 2% chitosan- 1% lactic acid as a solvent, with 10% honey shows optimum inclined values in all the tests, like thickness, folding endurance, weight, water vapor transmission, tensile strength, swelling ratio and antimicrobial activity, with specific reference to wound dressings. The film has water vapor transmission of 1680 g/m²/day, water absorption of 225%, tensile strength of 39.1N/mm² and elongation of 50.3%. There is a notable inhibition zone of 29 mm against S. aureus and 24 mm against E. coli in the case of chitosan-lactic acid-honey film. The film also arrests, microbes transmitting from the outside environment to wound bed, which can be used as an effective wound dressing material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=casting%20technique" title="casting technique">casting technique</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20dressings" title=" wound dressings"> wound dressings</a> </p> <a href="https://publications.waset.org/abstracts/75464/preparation-and-analysis-of-chitosan-honey-films-for-wound-dressing-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75464.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">244</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">1475</span> Simulation of Die Casting Process in an Industrial Helical Gearbox Flange Die</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Modabberifar">Mehdi Modabberifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrouz%20Raad"> Behrouz Raad</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahman%20Mirzakhani"> Bahman Mirzakhani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flanges are widely used for connecting valves, pipes and other industrial devices such as gearboxes. Method of producing a flange has a considerable impact on the manner of their involvement with the industrial engines and gearboxes. By Using die casting instead of sand casting and machining for manufacturing flanges, production speed and dimensional accuracy of the parts increases. Also, in die casting, obtained dimensions are close to final dimensions and hence the need for machining flanges after die casting process decreases which makes a significant savings in raw materials and improves the mechanical properties of flanges. In this paper, a typical die of an industrial helical gearbox flange (size ISO 50) was designed and die casting process for producing this type of flange was simulated using ProCAST software. The results of simulation were used for optimizing die design. Finally, using the results of the analysis, optimized die was built. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=die%20casting" title="die casting">die casting</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=flange" title=" flange"> flange</a>, <a href="https://publications.waset.org/abstracts/search?q=helical%20gearbox" title=" helical gearbox"> helical gearbox</a> </p> <a href="https://publications.waset.org/abstracts/7659/simulation-of-die-casting-process-in-an-industrial-helical-gearbox-flange-die" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7659.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">367</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">1474</span> The Effect of Micro/Nano Structure of Poly (ε-caprolactone) (PCL) Film Using a Two-Step Process (Casting/Plasma) on Cellular Responses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=JaeYoon%20Lee">JaeYoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Gi-Hoon%20Yang"> Gi-Hoon Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=JongHan%20Ha"> JongHan Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=MyungGu%20Yeo"> MyungGu Yeo</a>, <a href="https://publications.waset.org/abstracts/search?q=SeungHyun%20Ahn"> SeungHyun Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyeongjin%20Lee"> Hyeongjin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=HoJun%20Jeon"> HoJun Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=YongBok%20Kim"> YongBok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Minseong%20Kim"> Minseong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=GeunHyung%20Kim"> GeunHyung Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important factors in tissue engineering is to design optimal biomedical scaffolds, which can be governed by topographical surface characteristics, such as size, shape, and direction. Of these properties, we focused on the effects of nano- to micro-sized hierarchical surface. To fabricate the hierarchical surface structure on poly(ε-caprolactone) (PCL) film, we employed a micro-casting technique by pressing the mold and nano-etching technique using a modified plasma process. The micro-sized topography of PCL film was controlled by sizes of the micro structures on lotus leaf. Also, the nano-sized topography and hydrophilicity of PCL film were controlled by a modified plasma process. After the plasma treatment, the hydrophobic property of the PCL film was significantly changed into hydrophilic property, and the nano-sized structure was well developed. The surface properties of the modified PCL film were investigated in terms of initial cell morphology, attachment, and proliferation using osteoblast-like-cells (MG63). In particular, initial cell attachment, proliferation and osteogenic differentiation in the hierarchical structure were enhanced dramatically compared to those of the smooth surface. We believe that these results are because of a synergistic effect between the hierarchical structure and the reactive functional groups due to the plasma process. Based on the results presented here, we propose a new biomimetic surface model that maybe useful for effectively regenerating hard tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20surface" title="hierarchical surface">hierarchical surface</a>, <a href="https://publications.waset.org/abstracts/search?q=lotus%20leaf" title=" lotus leaf"> lotus leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-etching" title=" nano-etching"> nano-etching</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20treatment" title=" plasma treatment"> plasma treatment</a> </p> <a href="https://publications.waset.org/abstracts/40656/the-effect-of-micronano-structure-of-poly-e-caprolactone-pcl-film-using-a-two-step-process-castingplasma-on-cellular-responses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40656.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">376</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">1473</span> Properties Optimization of Keratin Films Produced by Film Casting and Compression Moulding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahamad%20Yousif">Mahamad Yousif</a>, <a href="https://publications.waset.org/abstracts/search?q=Eoin%20Cunningham"> Eoin Cunningham</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatrice%20Smyth"> Beatrice Smyth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every year ~6 million tonnes of feathers are produced globally. Due to feathers’ low density and possible contamination with pathogens, their disposal causes health and environmental problems. The extraction of keratin, which represents >90% of feathers’ dry weight, could offer a solution due to its wide range of applications in the food, medical, cosmetics, and biopolymer industries. One of these applications is the production of biofilms which can be used for packaging, edible films, drug delivery, wound healing etc. Several studies in the last two decades investigated keratin film production and its properties. However, the effects of many parameters on the properties of the films remain to be investigated including the extraction method, crosslinker type and concentration, and the film production method. These parameters were investigated in this study. Keratin was extracted from chicken feathers using two methods, alkaline extraction with 0.5 M NaOH at 80 °C or sulphitolysis extraction with 0.5 M sodium sulphite, 8 M urea, and 0.25-1 g sodium dodecyl sulphate (SDS) at 100 °C. The extracted keratin was mixed with different types and concentrations of plasticizers (glycerol and polyethylene glycol) and crosslinkers (formaldehyde (FA), glutaraldehyde, cinnamaldehyde, glyoxal, and 1,4-Butanediol diglycidyl ether (BDE)). The mixtures were either cast in a mould or compression moulded to produce films. For casting, keratin powder was initially dissolved in water to form a 5% keratin solution and the mixture was dried in an oven at 60 °C. For compression moulding, 10% water was added and the compression moulding temperature and pressure were in the range of 60-120 °C and 10-30 bar. Finally, the tensile properties, solubility, and transparency of the films were analysed. The films prepared using the sulphitolysis keratin had superior tensile properties to the alkaline keratin and formed successfully with lower plasticizer concentrations. Lowering the SDS concentration from 1 to 0.25 g/g feathers improved all the tensile properties. All the films prepared without crosslinkers were 100% water soluble but adding crosslinkers reduced solubility to as low as 21%. FA and BDE were found to be the best crosslinkers increasing the tensile strength and elongation at break of the films. Higher compression moulding temperature and pressure lowered the tensile properties of the films; therefore, 80 °C and 10 bar were considered to be the optimal compression moulding temperature and pressure. Nevertheless, the films prepared by casting had higher tensile properties than compression moulding but were less transparent. Two optimal films, prepared by film casting, were identified and their compositions were: (a) Sulphitolysis keratin, 20% glycerol, 10% FA, and 10% BDE. (b) Sulphitolysis keratin, 20% glycerol, and 10% BDE.

Casting defect is a very large issue in foundry shop which increases the rejection rate of casting and wastage of materials. The various parameters influences on casting process such as mold machine related parameters, green sand related parameters, cast metal related parameters, mold related parameters and shake out related parameters. The mold related parameters are most influences on casting defects in sand casting process. This paper review the casting produced by foundry with shrinkage and blow holes as a major defects was analyzed and identified that mold related parameters such as mold temperature, pouring temperature and runner size were not properly set in sand casting process. These parameters were optimized using different optimization techniques such as Taguchi method, Response surface methodology, Genetic algorithm and Teaching-learning based optimization algorithm. Finally, concluded that a Teaching-learning based optimization algorithm give better result than other optimization techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=casting%20defects" title="casting defects">casting defects</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20optimization" title=" parametric optimization"> parametric optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=TLBO%20algorithm" title=" TLBO algorithm"> TLBO algorithm</a> </p> <a href="https://publications.waset.org/abstracts/21826/a-review-on-parametric-optimization-of-casting-processes-using-optimization-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21826.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">728</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">1471</span> Biodegradable Polymer Film Incorporated with Polyphenols for Active Packaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shubham%20Sharma">Shubham Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Swarna%20Jaiswal"> Swarna Jaiswal</a>, <a href="https://publications.waset.org/abstracts/search?q=Brendan%20Duffy"> Brendan Duffy</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Jaiswal"> Amit Jaiswal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The key features of any active packaging film are its biodegradability and antimicrobial properties. Biological macromolecules such as polyphenols (ferulic acid (FA) and tannic acids (TA)) are naturally found in plants such as grapes, berries, and tea. In this study, antimicrobial activity screening of several polyphenols was carried out by using minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against two strains of gram-negative bacteria - Salmonella typhimurium, Escherichia coli, and two-gram positive strains - Staphylococcus aureus and Listeria monocytogenes. FA and TA had shown strong antibacterial activity at the low concentration against both gram-positive and gram-negative bacteria. The selected polyphenols FA and TA were incorporated at various concentrations (1%, 5%, and 10% w/w) in the poly(lactide) – poly (butylene adipate-co-terephthalate) (PLA-PBAT) composite film by using the solvent casting method. The effect of TA and FA incorporation in the packaging was characterized based on morphological, optical, color, mechanical, thermal, and antimicrobial properties. The thickness of the FA composite film was increased by 1.5 – 7.2%, while for TA composite film, it increased by 0.018 – 1.6%. FA and TA (10 wt%) composite film had shown approximately 65% - 66% increase in the UV barrier property. As the FA and TA concentration increases from 1% - 10% (w/w), the TS value increases by 1.98 and 1.80 times, respectively. The water contact angle of the film was observed to decrease significantly with the increase in the FA and TA content in the composite film. FA has shown more significant increase in antimicrobial activity than TA in the composite film against Listeria monocytogenes and E. coli. The FA and TA composite film has the potential for its application as an active food packaging. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20packaging" title="active packaging">active packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20film" title=" biodegradable film"> biodegradable film</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20barrier" title=" UV barrier"> UV barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a> </p> <a href="https://publications.waset.org/abstracts/135744/biodegradable-polymer-film-incorporated-with-polyphenols-for-active-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135744.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">152</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">1470</span> Investigation of Optical, Film Formation and Magnetic Properties of PS Lates/MNPs Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saziye%20Ugur">Saziye Ugur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, optical, film formation, morphological and the magnetic properties of a nanocomposite system, composed of polystyrene (PS) latex polymer and core-shell magnetic nanoparticles (MNPs) is presented. Nine different mixtures were prepared by mixing of PS latex dispersion with different amount of MNPs in the range of (0- 100 wt%). PS/MNPs films were prepared from these mixtures on glass substrates by drop casting method. After drying at room temperature, each film sample was separately annealed at temperatures from 100 to 250 °C for 10 min. In order to monitor film formation process, the transmittance of these composites was measured after each annealing step as a function of MNPs content. Below a critical MNPs content (30 wt%), it was found that PS percolates into the MNPs hard phase and forms an interconnected network upon annealing. The transmission results showed above this critical value, PS latexes were no longer ﬁlm forming at all temperatures. Besides, the PS/MNPs composite ﬁlms also showed excellent magnetic properties. All composite films showed superparamagnetic behaviors. The saturation magnetisation (Ms) first increased up to 0.014 emu in the range of (0-50) wt% MNPs content and then decreased to 0.010 emu with increasing MNPs content. The highest value of Ms was approximately 0.020 emu and was obtained for the film filled with 85 wt% MNPs content. These results indicated that the optical, film formation and magnetic properties of PS/MNPs composite ﬁlms can be readily tuned by varying loading content of MNPs nanoparticles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20film" title="composite film">composite film</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20formation" title=" film formation"> film formation</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title=" magnetic nanoparticles"> magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=ps%20latex" title=" ps latex"> ps latex</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a> </p> <a href="https://publications.waset.org/abstracts/65185/investigation-of-optical-film-formation-and-magnetic-properties-of-ps-latesmnps-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65185.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">255</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">1469</span> Design and Development of Mucoadhesive Buccal Film Bearing Itraconazole</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuvraj%20Singh%20Dangi">Yuvraj Singh Dangi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamta%20Prasad%20Namdeo"> Kamta Prasad Namdeo</a>, <a href="https://publications.waset.org/abstracts/search?q=Surendra%20Bodhake"> Surendra Bodhake</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this research was to develop and evaluate mucoadhesive films for buccal administration of itraconazole using film-forming and mucoashesive polymers.

Bioplastics have been used as food packaging materials. According to the European Bioplastics organization, bioplastics can be deﬁned as plastics based on renewable resources (bio-based) or as plastics which are biodegradable and/or compostable. Poly(lactic acid) (PLA) has an industrially importance of bioplastic polymers. PLA is a family of biodegradable thermoplastic polyester made from renewable resources. It is produced by conversion of corn, or other carbohydrate sources, into dextrose, followed by fermentation into lactic acid through direct polycondensation of lactic acid monomers or through ring-opening polymerization of lactide. The processing possibilities of this transparent material are very wide, ranging from injection molding and extrusion over cast ﬁlm extrusion to blow molding and thermoforming. In this study, PLA films were prepared by solution casting method. PLAs which are different molecular weights were plasticized with glycerol and the morphology of films was monitored by optical microscopy. Properties of mechanical and film of PLA were researched with the mechanical testing machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title="biodegradable">biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=bioplastics" title=" bioplastics"> bioplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=solution%20casting" title=" solution casting"> solution casting</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28lactic%20acid%29" title=" poly(lactic acid)"> poly(lactic acid)</a> </p> <a href="https://publications.waset.org/abstracts/33809/investigation-of-film-and-mechanical-properties-of-polylactic-acid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33809.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">378</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">1466</span> Antibacterial Activity of Nickel Oxide Composite Films with Chitosan/Polyvinyl Chloride/Polyethylene Glycol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Garba%20Danjani">Ali Garba Danjani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulrasheed%20Halliru%20Usman"> Abdulrasheed Halliru Usman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the rapidly increasing biological applications and antibacterial properties of versatile chitosan composites, the effects of chitosan/polyvinyl chloride composites film were investigated.

The molten metal or alloy poured into the rotating mold forms a hollow casting as the centrifugal forces lift the liquid along the mold inner surface. The rotational speed of the die was suggested to greatly affect the manner in which the molten metal flows within the mould and consequently the probability of the formation of a uniform cylinder. In this work the flow of the liquid metal at various speeds and its effect during casting were studied. The results suggested that there was a critical range for the speed, within which the produced castings exhibited best uniformity and maximum mechanical properties. When a mould was rotated at speeds below or beyond the critical range defects were found in the final castings, which affected the uniformity and significantly lowered the mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20casting" title="centrifugal casting">centrifugal casting</a>, <a href="https://publications.waset.org/abstracts/search?q=rotational%20speed" title=" rotational speed"> rotational speed</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20speed%20range" title=" critical speed range"> critical speed range</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/6659/effect-of-the-mould-rotational-speed-on-the-quality-of-centrifugal-castings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6659.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">445</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">1463</span> Development of a Robot Assisted Centrifugal Casting Machine for Manufacturing Multi-Layer Journal Bearing and High-Tech Machine Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Syed%20Ali%20Molla">Mohammad Syed Ali Molla</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Azim"> Mohammed Azim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Esharuzzaman"> Mohammad Esharuzzaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Centrifugal-casting machine is used in manufacturing special machine components like multi-layer journal bearing used in all internal combustion engine, steam, gas turbine and air craft turboengine where isotropic properties and high precisions are desired. Moreover, this machine can be used in manufacturing thin wall hightech machine components like cylinder liners and piston rings of IC engine and other machine parts like sleeves, and bushes. Heavy-duty machine component like railway wheel can also be prepared by centrifugal casting. A lot of technological developments are required in casting process for production of good casted machine body and machine parts. Usually defects like blowholes, surface roughness, chilled surface etc. are found in sand casted machine parts. But these can be removed by centrifugal casting machine using rotating metallic die. Moreover, die rotation, its temperature control, and good pouring practice can contribute to the quality of casting because of the fact that the soundness of a casting in large part depends upon how the metal enters into the mold or dies and solidifies. Poor pouring practice leads to variety of casting defects such as temperature loss, low quality casting, excessive turbulence, over pouring etc. Besides these, handling of molten metal is very unsecured and dangerous for the workers. In order to get rid of all these problems, the need of an automatic pouring device arises. In this research work, a robot assisted pouring device and a centrifugal casting machine are designed, developed constructed and tested experimentally which are found to work satisfactorily. The robot assisted pouring device is further modified and developed for using it in actual metal casting process. Lot of settings and tests are required to control the system and ultimately it can be used in automation of centrifugal casting machine to produce high-tech machine parts with desired precision. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bearing" title="bearing">bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20casting" title=" centrifugal casting"> centrifugal casting</a>, <a href="https://publications.waset.org/abstracts/search?q=cylinder%20liners" title=" cylinder liners"> cylinder liners</a>, <a href="https://publications.waset.org/abstracts/search?q=robot" title=" robot"> robot</a> </p> <a href="https://publications.waset.org/abstracts/40197/development-of-a-robot-assisted-centrifugal-casting-machine-for-manufacturing-multi-layer-journal-bearing-and-high-tech-machine-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40197.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">414</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">1462</span> Commercialization of Film Festivals: An Autobiographical Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96nder%20M.%20%C3%96zdem">Önder M.

Additionally, film festivals on common platforms have rapidly increased in numbers and diversity. On the one hand, no-charge applications result in excessive submissions; thus, it complicates the evaluation and selection process. On the other hand, festival’s high submission fees may make the distribution of films with a limited budget very difficult. Inspired by the author’s engagement with the film industry as both a pre-jury member of an international film festival and an applicant to many festivals, this study discusses the causes and consequences of the increasing commercialization of film festivals. The author’s double identity, both as a jury and an applicant, provides a comparative perspective through which one can unfold the different dimensions and dynamics in the film production and distribution processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercialization" title="commercialization">commercialization</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20distribution" title=" film distribution"> film distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20festivals" title=" film festivals"> film festivals</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20production" title=" film production"> film production</a> </p> <a href="https://publications.waset.org/abstracts/166277/commercialization-of-film-festivals-an-autobiographical-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166277.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">77</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">1461</span> Investment Casting Conditions with Tourmaline In-Situ</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kageeporn%20Wongpreedee">Kageeporn Wongpreedee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bongkot%20Phichaikamjornwut"> Bongkot Phichaikamjornwut</a>, <a href="https://publications.waset.org/abstracts/search?q=Duangkhae%20Bootkul"> Duangkhae Bootkul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The technique of stone in place casting had been established in jewelry production for two decades. However, the process were not widely used since it was limited to precious stones with high hardness and high stabililty at high temperature. This experiment were tested on tourmaline which is semi-precious gemstone having less hardness and less stability comparing to precious stones. The experiment were designed into two parts. The first part is to understand the phenomena of tourmaline under the heating conditions. Natural tourmaline stones were investigated and compared inclusions inside stones tested at temperature of 500 °C, 600 °C, and 700 °C. The second part is to cast the treated tourmaline with ion-implanation under the stones in place casting conditions. The results showed that stones were able to tolerate as much as at 700 °C showing the growths of inclusions inside the stones. The second part of this experiment were compared tourmaline with ion-implantation and natural tourmaline using on stones in place casting process at different stone setting types. The results showed that the cracks and inclustions of both treat and natural tourmaline with stones in place casting were propagate due to high stress of metal contractions. The stones with ion-implatation were more likely tolerate to cracks and inclusion propagations inside the stones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stone%20in%20place%20casting" title="stone in place casting">stone in place casting</a>, <a href="https://publications.waset.org/abstracts/search?q=tourmaline" title=" tourmaline"> tourmaline</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20implantation" title=" ion implantation"> ion implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20contraction" title=" metal contraction"> metal contraction</a> </p> <a href="https://publications.waset.org/abstracts/57747/investment-casting-conditions-with-tourmaline-in-situ" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57747.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">215</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">1460</span> The Effect of Increase in Aluminium Content on Fluidity of ZA Alloys Processed by Centrifugal Casting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20N.%20Jyothi">P.

Among ZA alloys, ZA 27 alloy has higher strength, low density with excellent bearing and wear characteristics. From the past research work, it is observed that in continuous casting as Al content increases, the fluidity also increases. In present work, ZA 8, ZA 12 and ZA 27 alloys have been processed through centrifugal casting process at 600 rotational speed of the mould. Uniform full cylinder is casted with ZA 8 alloy. For ZA 12 and ZA 27 alloys where the Al content is higher, cast tubes were not complete and uniform. The reason is Al may be acting as a refiner and reduce the melt flow in the rotating mould. This is mainly due to macro-segregation of Al, which has occurred due to difference in densities of Al and Zn. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=centrifugal%20casting" title="centrifugal casting">centrifugal casting</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20flow" title=" metal flow"> metal flow</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20engineering" title=" systems engineering"> systems engineering</a> </p> <a href="https://publications.waset.org/abstracts/4057/the-effect-of-increase-in-aluminium-content-on-fluidity-of-za-alloys-processed-by-centrifugal-casting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4057.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">328</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">1459</span> Structural, Optical and Electrical Thin-Film Characterization Using Graphite-Bioepoxy Composite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anika%20Zafiah%20M.%20Rus">Anika Zafiah M.

Advancement in packaging research leads to development of active packaging system with numerous properties such as oxygen scavengers, carbon-dioxide generating systems, antimicrobial active packaging, moisture control packaging, ethylene scavengers etc. In the active packaging, several additives such as essential oils, polyphenols etc. are incorporated into packaging film or within the packaging material to achieve the desired properties. This study investigates the effect on the structural, thermal and functional properties of different poly(lactide) – poly (butylene adipate-co-terephthalate) (PLA-PBAT) blend films incorporated with clove essential oil. The PLA-PBAT films were prepared by a solution casting method and then characterized based on their optical, mechanical properties, surface hydrophobicity, chemical composition, antimicrobial activity against S. aureus and E. coli, and inhibition of biofilm formation of E. coli. Results showed that, the developed packaging film containing clove oil has significant UV-blocking property (80%). However, incorporation of clove oil resulted in reduced transparency and tensile strength of the film as the concentration of clove oil increased. The surface hydrophobicity of packaging film was improved with the increasing concentration of essential oil. Similarly, thickness of the clove oil containing films increased from 36.71 µm to 106.67 µm as the concentration increases. The antimicrobial activity and biofilm inhibition study showed that the clove-incorporated PLA-PBAT composite film was effective against tested bacteria E. coli and S. aureus. This study showed that the PLA-PBAT – Clove oil composite film has significant antimicrobial and UV-blocking properties and can be used as an active food packaging film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20packaging" title="active packaging">active packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=clove%20oil" title=" clove oil"> clove oil</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28butylene%20adipate-co-terephthalate%29" title=" poly(butylene adipate-co-terephthalate)"> poly(butylene adipate-co-terephthalate)</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28lactide%29" title=" poly(lactide)"> poly(lactide)</a> </p> <a href="https://publications.waset.org/abstracts/136894/clove-oil-incorporated-biodegradable-film-for-active-food-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136894.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">151</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">1457</span> Formulation and Characterization of Active Edible Films from Cassava Starch for Snacks and Savories</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Raajeswari">P.

Cassava (Manihot esculenta) selected for making edible films are rich source of starch, and also it exhibit good sheeting propertiesdue to the high amylose: amylopectin content. Cassava starch was extracted by manual method at a laboratory scale and yielded 65 per cent. Edible films were developed by adding food grade plasticizers and water. Glycerol showed good plasticizing property as compared to sorbitol and polylactic acid in both manual (petri dish) and machine (film making machine) production. The thickness of the film is 0.25±0.03 mm. Essential oil and components from peels like pomegranate, orange, pumpkin, onion, and banana brat, and herbs like tulsi and country borage was extracted through the standardized aqueous and alkaline method. In the standardized film, the essential oil and components from selected peel and herbs were added to the casting solution separately and casted the film. It was added to improve the anti-oxidant, anti-microbial and optical properties. By inclusion of extracts, it reduced the bubble formation while casting. FTIR, Water Vapor and Oxygen Transmission Rate (WVTR and OTR), tensile strength, microbial load, shelf life, and degradability of the films were done to analyse the mechanical property of the standardized films. FTIR showed the presence of essential oil. WVTR and OTR of the film was improved after inclusion of essential oil and extracts from 1.312 to 0.811 cm₃/m₂ and 15.12 to 17.81 g/ m₂.d. Inclusion of essential oil from herbs showed better WVTR and OTR than the inclusion of peel extract and standard. Tensile strength and Elongation at break has not changed by essential oil and extracts at 0.86 ± 0.12 mpa and 14 ± 2 at 85 N force. By inclusion of extracts, an optical property of the film enhanced, and it increases the appearance of the packaging material. The films were completely degraded on 84thdays and partially soluble in water. Inclusion of essential oil does not have impact on degradability and solubility. The microbial loads of the active films were decreased from 15 cfu/gm to 7 cfu/gm. The films can be stored at frozen state for 24 days and 48 days at atmospheric temperature when packed with South Indian snacks and savories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20films" title="active films">active films</a>, <a href="https://publications.waset.org/abstracts/search?q=cassava%20starch" title=" cassava starch"> cassava starch</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticizer" title=" plasticizer"> plasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a> </p> <a href="https://publications.waset.org/abstracts/161837/formulation-and-characterization-of-active-edible-films-from-cassava-starch-for-snacks-and-savories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161837.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">80</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">1456</span> Structural and Optical Properties of Pr3+ Doped ZnO and PVA:Zn98Pr2O Nanocomposites Free Standing Film </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pandiyarajan%20Thangaraj">Pandiyarajan Thangaraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Mangalaraja%20Ramalinga%20Viswanathan"> Mangalaraja Ramalinga Viswanathan</a>, <a href="https://publications.waset.org/abstracts/search?q=Karthikeyan%20Balasubramanian"> Karthikeyan Balasubramanian</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20D.%20Mansilla"> Héctor D.

Because of the special requirements of space application, it is usually used in low temperature. The refractive index of Ge film is always changed with the temperature which has a great effect on the manufacture of high precision infrared optical film. Specimens of Ge single film were deposited at ZnSe substrates by EB-PVD method. During temperature range 80K ~ 300K, the transmittance of Ge single film within 2 ~ 15 μm were measured every 20K by PerkinElmer FTIR cryogenic testing system. By the full spectrum inversion method fitting, the relationship between refractive index and wavelength within 2 ~ 12μm at different temperatures was received. It can be seen the relationship consistent with the formula Cauchy, which can be fitted. Then the relationship between refractive index of the Ge film and temperature/wavelength was obtained by fitting method based on formula Cauchy. Finally, the designed value obtained by the formula and the measured spectrum were compared to verify the accuracy of the formula. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infrared%20optical%20film" title="infrared optical film">infrared optical film</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20temperature" title=" low temperature"> low temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20refractive%20coefficient" title=" thermal refractive coefficient"> thermal refractive coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=Ge%20film" title=" Ge film"> Ge film</a> </p> <a href="https://publications.waset.org/abstracts/71052/temperature-coefficients-of-the-refractive-index-for-ge-film" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71052.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">298</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">1454</span> “Self” and “The Other” in Dunkirk (2017)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebtesam%20Dessouki">Ebtesam Dessouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasaman%20Mousavi"> Yasaman Mousavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Christopher Nolan’s Dunkirk (2017) is not a conventional war film. He invites the audience to see the war from within, from the characters’ experiences, through suspense and fear, with the help of talented sound designers and musicians such as Hans Zimmer for an extra dimension creating those feelings. This experience of being among the surviving soldiers makes room for an interpretation of this film using the concept of the Self and the Other. The Self is the soldiers and the audience who try to make sense of their reality given limited information about the enemy and their situation, and the Other is the faceless enemy. However, this film can be taken under an even more detailed analysis theorizing that the Other also exists on different occasions in the film. Overall, Nolan leaves a lot of cues for the audience to track the Other and sometimes breaks the rules for the Other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=film" title="film">film</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunkirk" title=" Dunkirk"> Dunkirk</a>, <a href="https://publications.waset.org/abstracts/search?q=other" title=" other"> other</a>, <a href="https://publications.waset.org/abstracts/search?q=self" title=" self"> self</a> </p> <a href="https://publications.waset.org/abstracts/166703/self-and-the-other-in-dunkirk-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166703.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">72</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">1453</span> Synthesis and Characterization of Non-Aqueous Electrodeposited ZnSe Thin Film</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20R.%20Kumar">S.

The EDS spectroscopy shows the ratio of Zn & Se is 1.1 in case of annealed film. AFM analysis indicates the average roughness of the film reduces from 181nm to 165nm due to annealing of the film. The bandgap also decreases from 2.71eV to 2.62eV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title="electrodeposition">electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=non-aqueous%20medium" title=" non-aqueous medium"> non-aqueous medium</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a> </p> <a href="https://publications.waset.org/abstracts/22975/synthesis-and-characterization-of-non-aqueous-electrodeposited-znse-thin-film" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22975.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">486</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">1452</span> Accuracy of a 3D-Printed Polymer Model for Producing Casting Mold</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariangelo%20Hauer%20Dias%20Filho">Ariangelo Hauer Dias Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Gustavo%20Antoni%C3%A1comi%20de%20Carvalho"> Gustavo Antoniácomi de Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamim%20de%20Melo%20Carvalho"> Benjamim de Melo Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work´s purpose was to evaluate the possibility of manufacturing casting tools utilizing Fused Filament Fabrication, a 3D printing technique, without any post-processing on the printed part. Taguchi Orthogonal array was used to evaluate the influence of extrusion temperature, bed temperature, layer height, and infill on the dimensional accuracy of a 3D-Printed Polymer Model. A Zeiss T-SCAN CS 3D Scanner was used for dimensional evaluation of the printed parts within the limit of ±0,2 mm. The mold capabilities were tested with the printed model to check how it would interact with the green sand. With little adjustments in the 3D model, it was possible to produce rapid tools without the need for post-processing for iron casting. The results are important for reducing time and cost in the development of such tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20tooling" title=" rapid tooling"> rapid tooling</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20filament%20fabrication" title=" fused filament fabrication"> fused filament fabrication</a>, <a href="https://publications.waset.org/abstracts/search?q=casting%20mold" title=" casting mold"> casting mold</a> </p> <a href="https://publications.waset.org/abstracts/152307/accuracy-of-a-3d-printed-polymer-model-for-producing-casting-mold" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152307.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">142</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">1451</span> Film Studies: Definition, Current Status, and Future Perspectives for Cuba</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Guillermo%20Lloga%20Sanz">Carlos Guillermo Lloga Sanz</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20del%20Carmen%20Tamayo%20Asef"> Maria del Carmen Tamayo Asef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As an object of study in Cuban universities, cinema is still in its infancy. This is relevant considering the significance of cinema within the local political culture and its impact on countries of the region. Discussions about the medium have been carried out mainly in the field of film criticism. The objective of this article is to reflect on the divergences between film studies and film criticism taking into account formal and theoretical features and to explore the transcendence of this debate for the intellectual ambiance of the Island. Methodologically, the study relies on theoretical elaborations based on literature review and non-structure interviews with Cuban film critics and scholars. The study finds that the gradation proposed by the Anglo-Saxon tradition, where film studies are considered a “higher stage," compared to criticism and cinephilia, does not apply to the Cuban space. Instead, to assess the state of reflection on cinema in Cuba, it is essential to consider it a starry node traversed by epistemic, institutional, and geopolitical matrices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=film%20studies" title="film studies">film studies</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20criticism" title=" film criticism"> film criticism</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuban%20cinema" title=" Cuban cinema"> Cuban cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Cuban%20film%20studies" title=" Cuban film studies"> Cuban film studies</a> </p> <a href="https://publications.waset.org/abstracts/152140/film-studies-definition-current-status-and-future-perspectives-for-cuba" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152140.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1450</span> Porosities Comparison between Production and Simulation in Motorcycle Fuel Caps of Aluminum High Pressure Die Casting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Meethum">P.

Some parts such as fuel caps were a thin and complex shape. This part risked for porosities and blisters on surface if it only depended on an experience of mold makers for mold design. This research attempted to use CAST-DESIGNER software simulated the high pressure die casting process with the same process parameters of a motorcycle fuel cap production. The simulated results were compared with fuel cap products and expressed the same porosity and blister locations on cap surface. An average of absolute difference of simulated results was obtained 0.094 mm when compared the simulated porosity and blister defect sizes on the fuel cap surfaces with the experimental micro photography. This comparison confirmed an accuracy of software and will use the setting parameters to improve fuel cap molds in the further work. <p class="card-text"><strong>Keywords:</strong> <a
