    This investigation emphasizes the changes of the lift-to-drag ratio of an airfoil with the variation of ground clearance and angles of attack. Various ground clearances and angles of attack with a fixed speed of 30 m/s are applied to the NACA 4412 airfoil. Computational fluid dynamics (CFD) is used to calculate the aerodynamic coefficients acting on it. To study the influence of these two factors on the lift-to-drag ratio, 32 factorial design based on Design of Experiments (DOE) is utilized. A total of 9 numerical experiments were carried out with Ansys Fluent. When the angle of attack decreases, lift coefficient increases and drag coefficient decreases resulting in a high lift-to-drag ratio: also, the lower the ground clearance, the higher the lift-to-drag ratio. It shows the effectiveness of ground clearance and angle of attack. The analysis shows that either increasing ground clearance or using a higher angle of attack gives a decrement in the lift-to-drag ratio, but there is no interaction between them

    IntroductionPoultry red mites (PRMs, Dermanyssus gallinae), blood-sucking ectoparasites, are a threat to the poultry industry because of reduced production caused by infestation. In addition, tropical fowl mites (TFMs, Ornithonyssus bursa) and northern fowl mites (NFMs, Ornithonyssus sylviarum) are hematophagous, distributed in various regions, genetically and morphologically close to PRMs, and cause similar problems to the poultry industry. Vaccine approaches have been studied for PRM control, and several molecules have been identified in PRMs as candidates for effective vaccine antigens. The development of an anti-PRM vaccine as a universal vaccine with broad efficacy against avian mites could improve the productivity of poultry farms worldwide. Molecules that are highly conserved among avian mites and have critical functions in the physiology and growth of mites could be ideal antigen candidates for the development of universal vaccines. Ferritin 2 (FER2), an iron-binding protein, is critical for the reproduction and survival of PRMs and has been reported as a useful vaccine antigen for the control of PRMs and a candidate for the universal vaccine antigen in some tick species.Method and resultsHerein, we identified and characterized FER2 in TFMs and NFM. Compared with the sequence of PRM, the ferroxidase centers of the heavy chain subunits were conserved in FER2 of TFMs and NFMs. Phylogenetic analysis revealed that FER2 belongs to clusters of secretory ferritins of mites and other arthropods. Recombinant FER2 (rFER2) proteins from PRMs, TFMs, and NFMs exhibited iron-binding abilities. Immunization with each rFER2 induced strong antibody responses in chickens, and each immune plasma cross-reacted with rFER2 from different mites. Moreover, mortality rates of PRMs fed with immune plasma against rFER2 from TFMs or NFMs, in addition to PRMs, were higher than those of control plasma.DiscussionrFER2 from each avian mite exhibited anti-PRM effects. This data suggests that it has the potential to be used as an antigen candidate for a universal vaccine against avian mites. Further studies are needed to access the usefulness of FER2 as a universal vaccine for the control of avian mites

    Development of machine learning algorithms for multi-classification makes many unsolved classification problems approachable. The only way to find the best classifier is not just to get the best accuracy level by using it. So, we considered some more statistical measures to prove the efficiency of our model. Considering the wide use of neural network architectures in different fields we have selected one of the emerging architectures, Stochastic Configuration Network (SCN). It not just influentially impacts the accuracy and outperforms compared with some traditional algorithms in term of time complexity. In our work of classifying converter open circuit faults where we deal with 22 types of fault classes, SCN shows an efficient result to be used with. In this final year project, MATLAB-based programming will be used to conduct the system models and simulate the test results.Bachelor of Engineering (Electrical and Electronic Engineering

    In this study, the socioeconomic characteristics, cost and benefit, factors affecting yield determinants of cabbage and cauliflower production and constraints and challenges of production and marketing were investigated. The primary data were collected by interviewing 100 non-contract farmers in Myinmahti and Heho village tracts, 30 contract farmers in Kyauthtet, Heho and Thekhaung village tracts, and 34 sample market intermediaries in Kalaw Township during October to November, 2015. Descriptive analysis, cost and return analysis, marketing cost, margin and profit, production function analysis and SWOT analysis were used. According to the findings, both non-contract and contract farmers were at the primary education level. Home assets and luxury assets of non-contract and contract farmers were not significant. Regarding, the cost and return analysis, non-contract farmers can get more benefit cost ratio of rain-fed cabbage (3.02) and rain-fed cauliflower (3.55) than winter cabbage production of non-contract farmers (2.64), contract farmers (2.38) and winter cauliflower production of non-contract farmers (3.01). There were seven marketing channels along the cabbage and cauliflower supply chain. Retailers and township wholesalers got the higher profit than village collectors and commission men. Regarding to the winter cabbage production, the significant influencing factors were household head’s farming experience, farm size, total family labor cost, total hired labor cost, total material cost and access to credit for contract farmers while total family labor cost, total hired labor cost and access to credit for non-contract farmers. The significant factors of rain-fed cabbage yield were household head’s age, household head’s farming experience, farm size and total material cost of non-contract farmers. In the cauliflower production, household head’s education, amount of seed rate, total hired labor cost and access to credit were influencing on winter cauliflower production while only one influencing factor on rain-fed cauliflower production for non-contract farmers that was the amount of seed rate. In SWOT analysis, the serious factors of strengths, weaknesses, opportunities and threats of sample farmers were price information availability by mobile asset, not resistance pest and diseases, availability of local and export market and summer drought, respectively. SWOT analysis of market participants were price information availability by mobile phone asset, poor crop quality, high demand of product and high transportation cost, respectively. According to the study, farmers who had more experience can produce more products. Therefore, technical knowledge sharing should be promoted for farmers to get higher income

    The purpose of this study is to investigate the impact of play on preschool children’s social skills development. In addition, gender difference, age differences and differences among responsible agencies were further investigated. For quantitative study, preschool Children’s play and social skills were examined by using questionnaire survey method. In order to assess preschool children’s play behavior, the Penn Interactive Peer Play Scale (PIPPS) was used. In order to assess preschool children’s social skills, the Preschool and Kindergarten Behavior Scales-2ndedition (PKBS-2; Merrell, 2002) was used. Qualitative study was conducted by using play and social skills checklist, preschool teacher interview form and naturalistic observation. The study began with a quantitative approach as a primary method, and then a qualitative follow up study was conducted to support the quantitative results. A total of 565 children from 12 preschools and their class teachers and parents were participated as the sample in this study.By using the descriptive procedure with the data obtained from the teacher-rated and parent-rated questionnaire, play behavior of preschool children can be estimated. According to teacher rating, the mean score of play disruption is the highest and that of play disconnection is the lowest among play behaviors. A child with a high score in each subscale was considered as a child with good play behavior.According to gender, the mean value of play behavior of female preschool children was higher than that of male preschool children. By means of responsible agencies, the mean score of play behavior of children under DSW was highest and that of children under MOE was the lowest. By different age groups, the mean score of children who are over five years old was highest among other age groups. The older the children’s age, the more positive play behavior they have. Concerning with social skills development, the mean score of social cooperation is the highest and that of social interaction is the lowest among other social skills. A child with a high score in each subscale was considered as a child with good social skills. Based on gender difference, The mean value of social skills of female preschool children was higher than that of male preschool children. The mean score of social skills of children from preschool under DSW was highest and that of children from preschools under MOE was lowest. In comparing according to age groups, the mean score of children who are over five years old was highest among other age groups. The older the children’s age, the higher the social skills they have.Moreover, it can be reasonably said that according to parents and teacher rating, social skills development of preschool children were highly correlated with their play

    BackgroundIn Southeast Asian countries, including Myanmar, poultry farming is a major industry. In order to manage and maintain stable productivity, it is important to establish policies for biosecurity. Infectious respiratory diseases are a major threat to poultry farming. Avian influenza and Newcastle disease have been reported in Myanmar, but no scientific information is available for other respiratory pathogens, such as mycoplasmas and infectious bronchitis virus (IBV). Identifying the genotypes and serotypes of IBVs is especially important to inform vaccination programs. In this study, we detected Mycoplasma gallisepticum (MG), M. synoviae (MS), and IBV in several poultry farms in Myanmar.ResultsSamples were collected from 20 farms in three major poultry farming areas in Myanmar, and MG, MS, and IBV were detected on two, four, and eight farms, respectively, by polymerase chain reaction. Phylogenetic analysis revealed that the observed MG and MS isolates were not identical to vaccine strains. Three different genotypes of IBV were detected, but none was an unknown variant.ConclusionsMycoplasmas and IBV were detected on poultry farms in Myanmar. Periodic surveillance is required to establish the distribution of each pathogen, and to institute better vaccine protocols
