The results of the present work showed that Remote Sensing (RS) has reduced fatigue and thermal cracks. Moreover, for modified asphalt samples, tests of Marshall stability, flow, resilience modulus, repeated load axial, uniaxial creep and indirect tensile fatigue were carried out. against fatigue of asphalt mixtures. However, all samples showed longer fatigue life than the base mixture. Fatigue performance improvement for all samples was between 5 and 38%. Organic oil-modified bitumens have the best performance compared to other modified bitumens. Containing 4% rhamnolipid biosurfactant increased by 213%. This indicates the excellent performance of bitumen modified with rhamnolipid biosurfactant against fatigue of asphalt mixtures. Comparing the results of this study with the results of previous studies, it can be concluded that samples containing rhamnolipid biosurfactant had a better behavior against fatigue compared to samples made with bitumen modified with other oils.","PeriodicalId":132051,"journal":{"name":"ENG Transactions","volume":"1 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133080613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an experimental study on how to enhance the machining processes of the AISI H13 hot work tool steel by implementing a decent cooling and lubrication technic throughout the machining processes. Proper machining conditions and parameters for industrial applications are analysed namely; dry conditions, wet conditions of Boron and nano additive solutions. The flow rate is measured and calculated. The cutting fluid in different concentration is used in the hard-turning experiments. Different cutting speeds (100,150,200m/min), feed rates (0.03, 0.06, 0.09mm/rev), and a constant depth of cut (0.2mm) are considered. The assessments are equated against the machining forces and temperatures, using 12 pieces of PVD coated ceramic type turning insert-cutting tools. The results of experimental investigation show that the wet machining conditions have substantial effects across all the machining standards. It is indicated that the machining temperature is reduced tremendously during the both cases of wet machining conditions. Thus, wet machining by adding additives demonstrats enhanced machining conditions at the medium feed rates and lower cutting speeds by reducing the cutting force, which is a threat to the tool life.","PeriodicalId":132051,"journal":{"name":"ENG Transactions","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130007254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hyperthermia therapy using magnetic nanofluid is one method to regulate and optimize temperature, which is a substantial challenge in practice. The generated heat through the magnetic coil using magnetic nanoparticles in the tumor is closely associated with the dispersion of particles, frequency, magnetic field intensity, and the property of the tissue. Therefore, with magnetic nanoparticles injected into tumor tissue and subjects to an alternating magnetic field with high amplitude and frequency, tumor tissue temperature rises, which could lead to destroying cancer cells. In this study, to simulate the magnetic field intensity at different parts of the experiment and to solve heat transfer equation, a finite element method using COMSOL Multiphysics has been used. Then, to verify our model, an experimental setup was used to measure temperature distribution in an agarose gel with two different nanofluid concentrations for dispersed and concentrated injections. Simulation results have been compared with experimental ones to show the model's accuracy. Results indicate that the magnetic field in different parts of the gel is not the same, but the differences are insignificant. Temperature distribution for both types of nanofluid in dispersed and concentrated injections has a behavior like a polynomial function with a degree of three. Compared to dispersed injection, a higher temperature is observed in concentrated","PeriodicalId":132051,"journal":{"name":"ENG Transactions","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132291856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tempered glass demolishes into small fragments with harsh corners when it fractures. Because of the fracture pattern (fractures in pieces), heat- or chemically pre-stressed glass panel cannot be called safety glass panel until laminated. Bending experiments were run, and the bending strength of single-layer tempered and float glass panel was calculated using well-known formulae. In the context of float and tempered glass panel, the computed values for surface complexation using ultimate strain were matched to the bending strength findings. The following question arises: are the strains measured in the centre of the glass and towards the edge comparable? Strain measurements were also taken on the surface of packed samples in the centre and towards the edge of the glass. Fractures with tiny sharp points characterize glass errors. Despite careful manufacturing and maintenance of glass panes, hits by sharp particles or environmental effects can produce surface flaws. Glass manufacturing processes, such as edge polishing, have an impact on glass strength and can produce defects that spread during the glass's lifespan.","PeriodicalId":132051,"journal":{"name":"ENG Transactions","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127278243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
