Flame retardant application plays a crucial protective function in saving life and property by reducing the overall fire risk associated with using highly combustible raw materials in products such as textiles, clothing, composites, plastics etc. Recently, there has been an ever-growing demand for new flame retardant product options; recognizing not only to ensure a favorable sustainable profile but also a durable and cost effective product. Here in, a well-structured study of the impact to flammability of adding Antimony Trioxide and replacements in suitable combinations with Hexachloroethane to pigment print pastes is presented based on the principle of synergism. It was concluded that there is no significant flame retardant effect up to 30 ppm concentration of Antimony Trioxide or Zinc Borate and a good ratio of Zinc Borate to Hexachloroethane is 4∶1 to give rise to synergism. It was also found that there is no adverse effect on the properties of the print.","PeriodicalId":395453,"journal":{"name":"2017 Moratuwa Engineering Research Conference (MERCon)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132668226","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}

However, the effectiveness of market sales promotions is not clear as they primarily rely on number of likes, sharing, and comments than the actual customer conversions. Moreover, it is unclear what factors to be considered while launching and running a successful market sales promotion campaign. We identify those factors through a case study of twelve market sales promotions from different banks in Sri Lanka. The research was conducted as a qualitative analysis based on the Straussian grounded theory, because this version of grounded theory allows a literature review for theoretical sampling, concept development, and defining properties and dimensions. Data were gathered through a set of interviews and observations. We found that six factors that mainly contribute to a successful market sales promotion campaign, namely the type of the promotion, target audience, timing of campaign, platform for communication, mode of communication, and resources. Moreover, platform rules, regulations, and organizational constraints affect the strength of the relationship between the independent and dependent factors.","PeriodicalId":395453,"journal":{"name":"2017 Moratuwa Engineering Research Conference (MERCon)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116938726","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}

Despite the fact that concrete gives protection against corrosion, aggressive environmental conditions can lead to the corrosion of the reinforcement bars embedded in concrete. This may affect the strength of the concrete structures which leads to catastrophic failures during the service. Assessment of the extent of corrosion in embedded reinforcement bars nondestructively is the main objective of this research work. Grade M30 concrete mixture was used for the preparation of rectangular square blocks as testing samples. Concrete specimens with embedded steel bars of 10 mm, 16 mm, 20 mm and 25 mm diameters have been subjected to accelerated corrosion using ‘Impressed Current Technique’ for different time periods. The ultrasonic velocities through the concrete samples with corroded reinforcement bars were measured against the corrosion time and the bar diameters. For these measurements Portable Ultrasonic Nondestructive Digital Indicating Tester (PUNDIT) was used. The weight loss due to corrosion of the reinforcement bars were measured subsequently, and those readings were evaluated against the ultrasonic velocities. The ultrasonic velocity decreases with the time and the extent of corrosion.","PeriodicalId":395453,"journal":{"name":"2017 Moratuwa Engineering Research Conference (MERCon)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117239919","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}

The excessive loading placed on the foot due to obesity can cause damage to the soft tissue and musculoskeletal structure which leads to foot discomfort and the development of foot pathologies. Experimental and computational methods of analysis were combined in this study to analyse the effects of obesity on the foot. It has been shown previously that foot pathology often starts subcutaneously and spreads towards the foot plantar. Hence the effect of obesity on the biomechanical behaviour of the foot was studied through an internal study of the bone structure using the modelling technique of finite element analysis. A 3-D anatomically correct model of a foot was created using density segmentation techniques reconstructed from Magnetic Resonance (MR) images. A non-linear finite element analysis of the reconstructed foot during balanced standing was conducted. The biomechanical differences were further classified through an external study of the foot using a gait measuring system. The finite element model of the obese foot suggests greater peak contact pressure. Experimental results suggest reduced joint angles and adjustments in the gait pattern. Preliminary results show that some differences in the biomechanical behaviour of the obese and non-obese feet are present where obese subjects compensate for the greater loading through changes in their gait.","PeriodicalId":395453,"journal":{"name":"2017 Moratuwa Engineering Research Conference (MERCon)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117147064","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}
