Therefore, de-anonymizing e-mail accounts are very important and necessary to identify the real person behind them. It helps legitimate account users to bring them before the court for necessary actions. Once the law enforcement has enough evidence against a person, they can lay criminal charges and a judge decides if the accused should be released or remanded. Therefore, this research focuses on “de-anonymizing protocol for e-mail accounts” to identify the real identity of them. The de-anonymizing protocol is a detection and investigation of the real user behind an anonymous e-mail address. The detection system of the de-anonymizing protocol can be modified and changed according to the nature of the crime. The proposed investigation methodology can be applied for any email service provider 2021-03-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5472 Title: Development and validation of a portable paper-based low-cost electrochemical sensor for the detection of monosodium L-glutamate in food Authors: Joseph, Ornella A; Dineesha, Nipuni; Kaumal, M. N. Abstract: Monosodium L-glutamate (MSG) is a common ingredient that is added to food to enhance its taste. However, due to the negative perception of consumers towards MSG, most food manufacturers do not inform customers if MSG has been added to food. This work describes the development and validation of a low-cost electrochemical microfluidic paper-based analytical device (µPAD) for the rapid, on-site detection of MSG in food samples. This device is a portable, low-cost, one-time sensor that can be used on the field even directly without sample preparation. This would greatly benefit groups of society such as Public Health Inspectors and individuals who regularly consume fast food. The µPAD was fabricated with a three-electrode system consisting of a working electrode modified with Co3O4 nanoparticles, a pseudo reference electrode, and a counter electrode. The device is tested using food samples spiked with MSG 5 g/L. The test results prove that the device can be used as a qualitative sensor to detect MSG in food with the limit of detection 0.82 g/L 2021-03-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5471 Title: Determination of factors associated with farmers’ choice of Paddy Marketing Board Supply Chain in Ampara District Authors: Riswan, A. F. M. M; Geretharan, Thivahary Abstract: The objective of this study was to assess the factors associated with farmers’ choice of Paddy Marketing Board (PMB) supply chain to sell their paddy in Ampara District. The research was conducted among 100 farmers from ten Divisional Secretariat divisions in the coastal belt of Ampara District. Stratified random sampling was used to select the farmers of PMB supply chain and private sector supply chain in the study area. A pre-tested semi-structured questionnaire was used to collect the data. Binary logistic regression was deployed to test the hypotheses by using the Statistical Package for Social Sciences (SPSS). Results revealed that only 34% of farmers had knowledge about the PMB operation among the private sector suppliers. The analysis further indicated cultivating only on own land (p<0.05) positively impacted on the choice of PMB. On the other hand, the scale of farming if less than 5 acres (p<0.01), if more than 10 acres (p<0.05), educational level of the farmer if below secondary level and tertiary level (p<0.05) were negatively impacted on the choice of PMB. However, there was no impact with gender, contacts of extension services, transport facilities and time of sales after harvest in the choice of PMB supply chain of farmers. Late operation of PMB is the major issue in this district, it has to be restructured to attract the commercial farmers. 2021-03-30T00:00:00Z http://ir.lib.seu.ac.lk/handle/123456789/5470 Title: A review on role of Mycorrhizal Fungi in plant disease management Authors: Himaya, S. M. M. S; Sivasubramaniam, N; Afreen, S. M. M. S Abstract: Plant diseases become one of the significant threats in crop production worldwide which causes billion-dollar yield losses directly. Many approaches found to suppress various disease effects on crops. Among all the options available, biotic control of crop diseases promises one and in which Mycorrhizal Fungi (MF), especially endo mycorrhizae would play a significant role. Many reviews have reported on the interface mechanisms among Arbuscular Mycorrhizal Fungi (AMF) and plant pathogens. It includes improvements in plant nutrition, competition for nutrient and photosynthates and antibiosis. Depending on the infections and the ecological conditions, all mechanisms may be involved. Studies revealed that AMF, Glomus sp and Gigaspora sp. are the best models used to control plant fungal and bacterial diseases. Further, Rhizophagus sp, Funneliformis sp and Claroideoglomus sp. are few of the excellent applicants of AMF shows better potential to oversee viral infections in plants. However, sufficient researches are not done so far to focus on exact stages of infection side effects of AMF when it incorporates with the crops to control pathogens. Future research on the AMF-mediated promotion of crop quality and productivity is therefore required with exploring the adverse effects of AMF, with emphasis on plant disease management. It can conclude that when biological management techniques are paired with effective AMF tactics while considering the environmental protection measures, a sustainable way of plant disease management is possible 2021-03-30T00:00:00Z
