This article presents an analytical method to determine the distance of a bank filtration well from a river in commensuration with the desired percentage of bank filtrate and removal of pathogenic compounds. Applying least squares optimization technique using Marquardt algorithm, the unknown parameter, distance of the well from the river has been estimated. The travel time in commensuration with the desired percentage removal of pathogenic compounds has been ascertained using the first-order decay equation.
For evaluating effectiveness of the technique, the physico-chemical and biological parameters of extracted bank filtrate from 22 wells located in the vicinity of the River Ganga and the Upper Ganga Canal network at Haridwar have been analysed for the non-monsoon and the monsoon periods. The physicochemical parameters of the extracted water showed concentration much below the acceptable limits, except turbidity. The percentage removal of turbidity in the extracted water was found about 98 and 76 during the monsoon and non-monsoon periods respectively, in comparison to water from the river/canal. The count of biological parameters, viz. total coliform and faecal coliform in the extracted water is removed considerably (65% to 85%), but is found above the acceptable limit. The reason could be mixing of bank filtrate with the rich constituents in the groundwater. It is suggested that bank filtration dilutes groundwater quality and can be regarded as a technique to conjunctive management of surface and groundwater quality.

The most common type of odontogenic tumours is odontomas. Generally, they are benign and asymptomatic in nature. This paper describes two varieties of odontomas in two different cases. In first case a compound odontoma present in maxillary anterior region lead to over retention of primary teeth and non eruption of permanent teeth. Retained deciduous teeth and the lesion were removed and permanent teeth were allowed to erupt and orthodontic treatment was done. In 2nd case a complex odontoma was incidentally found when patient reported for extraction of mandibular third molar which was surgically excised. The results achieved indicate that the early diagnosis of odontomas allows the adoption of a less complex and less expensive treatment and ensures better prognosis.Keywords

Education theories stress not only societal context of education, but also educational philosophy, anthropology and psychology of learning. A formal curriculum theory, viz. Taba–Tyler rationale, has been proposed to incorporate philosophical, sociological, anthropological and psychological contexts of engineering education in the curriculum. The newly developed undergraduate curriculum at the Indian Institute of Technology Ropar is based on such education theories and has been presented as a case study. It has been demonstrated that the resulting curriculum can lead to unique courses that collectively bring out unique features such as core competency, strong connection to society, hands-on learning, creativity and innovation.Keywords
