Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is a compilation of four dissertations based on experimental projects presented to Vidyasagar University by four final year undergraduate students of Jhargram Raj College, Jhargram-721507, West Bengal, India, under my supervision. The topics were selected while I was giving instructions on laboratory work to undergraduate students there. The subjects embody a detailed idea of OPAMP in electronics, its different applications, some new experiments based on OPAMP, which yield qualitative and quantitative information about OPAMP. The second chapter is based on the idea of OPAMP. The third chapter is based on the characteristics of differential amplifier, logarithmic amplifier, and antilogarithmic amplifier mode of OPAMP. Exhaustive studies on measuring the thermo-emf of a thermo couple with two and one junction using inverting amplifier mode of OPAMP is given in chapter four. Finally in the fifth chapter a dissertation on the measurement of the variation of Zener breakdown voltage with temperature using differential amplifier mode of OPAMP is given. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book compiles three dissertations on experimental projects based on pollution hazards due to electric field on the germination of seeds. The sprout length of gram and pea seeds during the time of germination of some seeds in open-air condition decreases with increase in electric field and voltage. Corresponding graphs show non-linear variations. The cut-off or threshold voltage at which germination stops, is also determined by extrapolation and the corresponding electric field is computed. Thus electric field has negative effect on the germination of seeds. This may have an impact in agriculture sector, specifically, in the process of preservation of seeds in cold storages. 116 pp. Englisch.…

The topics embody a detailed idea of Wheatstone s Bridge as a basic tool for electrical circuit networks, its different applications in direct and alternating circuits, some new experiments based on it. The first and second chapter gives ideas of Wheatstone s Bridge and different types it. The third chapter determines variation of low resistance of manganin wire with the help of Kelvin double Bridge. In the fourth chapter, the variation of magnetic permeability and susceptibility of different media, viz. steel wool of different concentrations, inside a solenoid are investigated using Anderson s Bridge. The study on measuring the variation of dielectric constant and polarisability of paraffin wax doped with different concentrations of lamp black carbon is investigated and compared with the help of Schering s Bridge and De Sauty s Bridge. 92 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The study on defect and diffusion is an important area due to its present status in technology and so this book has its relevance still now. From the theoretical point of view Lattice Statics and Atomistic Continual Models in chapter one have produced, with all their approximations, some interesting and quite consistent results for relaxations due to a vacancy, its formation energies and divacancy binding energy in some FCC metals. Pseudopotential approach of chapter two produces general formulations for the calculation of defect parameters in case of vacancy in FCC metals for self and impurity diffusion. In the third chapter the experimental measurement of impurity diffusion parameters in Pb-Sn system is shown. The results are consistent with earlier experiments and theoretical values by pseudopotential method. To understand the kinetic behaviour of interfacial reactions in Ag-Sn thin film couples the contact and composite resistance measurements are done which indicate that interfacial reactions start at room temperature. X-ray diffraction indicates the growth of -Ag3Sn phase immediately after deposition and TEM and SEM studies confirm its presence. 248 pp. Englisch.…
