Failure Load Prediction for Dapped-End Beam

Dapped-end beams are members of precast concrete structures that widely used nowadays in construction industry, especially in buildings and bridges due to its good lateral stability. The design analysis of dapped-end connections is complex and the re-entrant corner is identified as the weakest point because stress concentration develops in that area, which also known as disturbed regions. The accuracy of different codes and approaches in predicting failure load is yet to be fully explored. Therefore, investigation of the relative performance of different methods in predicting failure load capacity is crucial to be done. Besides, the incident of collapsed of Concorde Bridge has risen up many researchers’ attention and interest to conduct deeper research on design and strengthening of dapped-end connections to determine the load capacity for future design work purposes. Thus, this research project intended to determine the failure load of the dapped-end beams by using twodimensional non-linear finite element analysis (FEA) software called Vector2 and also using PCI design approach. The results from the Vector2 and also from PCI design approach will be used to compare with the load capacity obtained experimentally by Wang et al (2005) in their experimental research project as validation to determine which code or method is providing better accuracy in determining the failure load capacity. The analysis result obtained from FEA software and PCI Design Handbook is 47.6kN and 36.7kN, which is quite near compared to the experimental value, 42.24kN. Parametric study conducted to determine the sensitivity of different dapped-end parameters on the failure load capacity. As a conclusion, it is proven that the FEA software can be used to predict the failure load capacity accurately and can be used for parametric study

Studies of solute-solvent interactions and miceller behaviour of complexes of copper (II) palmitate with substituted phenylthiourea and 2-amino benzothiazole in methanol-benzene mixture

In this work, synthesis of copper (II) surfactants followed by the complexation of each other with the molar ratio of 1:2 dissolving in ethanol have been reported. The purity of the resulting complexes of the general formula- CP(PTU )T , CP(BTA)T was checked by thin layer chromatography and characterized on the basis of elemental analysis. Their spectral studies are also included and data suggest that Cu (II) phenylthiourea mixed system binds through the donor ability of nitrogen to transition metal. The magnetic moment studies suggest the dimeric nature of the complexes. IR, NMR, ESR spectral details confirm that complexation has taken place successfully and dada suggest that the complexes possess elongated octahedral geometry. Density, Molar Volume, Apparent Molar Volume of these complexes was investigated in non-aqueous solvent at various concentrations by Springel Pyknometer to understand the nature, critical micelle concentration and micelle characteristics of the complexes. Overall, the CMC values were found to be decreased with increasing average molecular weight of soap complex. The solute - solute interactions were found to be greater before CMC whereas solute-solvent interactions were found greater after CMC

Determinants of FDI inflows to developing countries: a panel data analysis

The aim of this paper is to identify, by estimating a panel econometric model, the factors determining FDI inflows to developing countries over a long period. The study is based on a sample of 32 developing countries. In our analysis, FDI inflows are modeled as a function of the market size, total reserves, infrastructure, labour cost and degree of openness for the host countries. Using data from 1982 to 2008, a panel data estimator suggests that the market size, total reserves, infrastructure and labour costs are the main determinants of FDI inflows to developing countries

A study on management of neglected shaft femur fractures by open intramedullary nailing

Background: Fracture shaft of femur is a common and major musculoskeletal injury and in most of the cases the patients are immediately brought to hospitals for specialist orthopaedic management. However, it is not uncommon in developing countries especially in rural India for these injuries to be neglected initially due to the wide spred practice of quackery. The purpose of this study was to evaluate the effectiveness of open intramedullary nailing in the management of neglected fracture shaft femur patients in relation to achievement of union and functional results.Methods: This was a prospective observational study conducted on 20 patients presenting to the Orthopaedic OPD of SHKM Government Medical College Hospital, Nalhar, Nuh, Haryana between August 2013 and December 2016, with a diagnosis of neglected fracture shaft of femur. All the patients underwent single stage open reduction and internal fixation with interlocking intramedullary nails. The patients were followed up for a period of 1 year. The patients were analysed for union and functional results.Results: All the fractures united and the average time of union was 22.6 weeks. The average range of motion of the knees improved from 34 degrees in the preoperative period to 114.5 degrees in the postoperative period.  Two patients developed superficial infections at the incision site which resolved with local drainage and oral antibiotics. All the patients were able to return to their preinjury occupation.Conclusions: Thus results of our study demonstrate that single stage open intramedullary nailing is a safe and effective surgical procedure for the treatment of neglected fractures of shaft of femur.

Modern use of modified Sequencing Batch Reactor in wastewater Treatment

If wastes are not properly managed, it may seep into the earth and aquifers, polluting both the surface and the water table. For public health reasons, leachate is considered a major environmental hazard due of its poisonous and hardy components. Because of this, it must be collected and processed adequately before being released into nature. Currently, there is no single unit procedure for appropriate leachate treatment since traditional wastewater treatment techniques are unable to degrade harmful chemicals contained in the leachate to a suitable level. Consequently, there has been an increase in the study of various leachate treatment procedures in order to maximise operational versatility. Various strategies have been used to degrade the leachate based on its properties, discharge requirements, technological possibilities, regulatory restrictions, and cost concerns. Sequencing batch reactor (SBR) treatment systems for landfill leachate were lauded for their operating flexibility, shock load resilience, and high biomass retention in the interest of long-term sustainability for the environment. Therefore, the current work objective is a deeper study of the features of SBR to identify prospects and unresolved problems in this process. The content analysis method of scientific publications from rating journals indexed in Scopus, PubMed, ScienceDirect, ResearchGate, Google Scholar on the totality of the keywords of this study in various combinations was applied; selection and synthesis of the main characteristics SBR to identify gaps in this area and prospects for future research. An in-depth analysis of the benefits and drawbacks of different leachate degrading processes is provided in this article. The role of integrated leachate treatment technologies with SBR was also highlighted. The effects of various materials, techniques, tactics, and configurations on leachate treatment were also explored in the paper. Critiqued SBR system environmental and operational factors were addressed. Readers of this work are expected to get a better understanding of SBR studies for leachate treatment and to use this information as a guide for their own research in this field. It uses the fill and draw activated sludge system with clarifier and intermittent aeration mode, where all the metabolic reactions and the separation of solid-liquid takes place in a unit tank through a timed control sequence in a non-steady state, variable capacity and suspended growth biological wastewater treatment system. The simultaneous nitrification, denitrification, and phosphorus removal are made possible by combining anaerobic and aerobic processes
