Abstract: Biosynthesis of nanoparticles is an important area in the field of nanotechnology, which has economic and ecofriendly benefits over chemical and physical methods of synthesis. In the present study leaf extract of Ocimum basilicum L. var.thyrsiflorum was assessed for the synthesis of Silver nanoparticles using 1mM Silver Nitrate aqueous solution. Nanoparticles were characterized with the help of UV-Vis absorption spectroscopy analysis, Fourier Transform Infrared (FTIR) analysis, Scanning Electron Microscopy (SEM) and EDX analysis. The Synthesized nanoscale particles were confirmed by analyzing the excitation of Surface Plasmon Resonance (SPR) using UV–visible spectrophotometer at 436nm. Further SEM analysis confirmed the range of particle size between 22 to 42 nm. Fourier transform infrared spectrum confirmed the presence of high amount of phenolic compounds in the plant extract, possibly influenced the reduction process and stabilization of nanoparticles.

Abstract: This project Research paper for detecting magnetic fields in the extremely low frequency range and extremely low noise are developed, including the antenna, transformer base frequency amplifier. Each component is described with relevant cut-offs which allow a large variation of receivers to be easily designed for any magnetic field loop coil sensing in the ultralow frequencies noise range. This paper introduces a new ELF noise signal Inductor Loop-sensor design and finds stability for pre-amplifier. A system using different impedance value base antenna is developed further that has been used extensively in measurement application in the frequency below range of extremely low using tools such as MATLAB software base.

Abstract: Every organization has its own culture. Since many employees spend 40 or more hours at their workplace, their organization’s culture noticeably affects both their work lives as well as their personal lives. The identity of the company becomes identity of the people who work in it. Organizational culture refers to the beliefs, ideologies, principles and values that the individuals of an organization carve up. This culture is a determining factor in the success of the organization. It defines the way how an employee interacts and completes a given task. It was in this context that a study was undertaken to see the cultural match among the Essar employees based on Daniel Denisons (1990) model which asserts that organizational culture can be described by four general dimensions – Mission, Adaptability, Involvement and Consistency. For this, a survey was conducted on 100 employees of the firm; their views were taken and recorded. Seven hypotheses were made and tested. Results revealed positive correlation between Adaptability and Mission. Results also showed that there is high positive correlation between Adaptability and Consistency. When checked whether there is a relationship between Adaptability and Involvement, the correlation coefficient came out to be positive. Data also reveals that there is a positive correlation between mission and involvement. Data Analysis using chi square test revealed that there is high dependence of work and involvement on each other. The organization as a whole and the employees are a content lot and they believe in strong cultural values and strict code of adherence.

Abstract: Globalization and market economy are impacting Indian society in an unprecedented manner. The impact is visible on India’s socio-economic policies as well. Today India, like many other nations is in the race of achieving higher rate of economic growth to bring development, prosperity and happiness to its people. However, it’s not clear whether economic well-being is proportionately related to the happiness quotient which is simultaneously affected by several other socioeconomic-psychological factors. For a long time, the Gandhian model worked as an inspiration behind the socio-economic policies in India. Gandhi’s philosophy made clear distinction between the need and greed at a subtle psychological level so as to avoid conflict, maintain social harmony and ensure sustainability. However, the new socio-economic policies follow different mandate. In the light of the twin complimentary Gandhian concept of antyodaya and sarvodaya this paper discusses how social and service design in the contemporary context can help create a more sustainable future by striking a balance between economic development and social well-being at large.

Abstract: Today, digital Systems play a significant role in human’s life. And it is the reason to call existing technology, “The Digital Age”. Digital circuits are utilized in industry, trade and science. The most commonly used electronic devices like computers, cell-phones, digital cameras, televisions,… are designed by digital circuits. Digital circuits are composed of smaller circuits titled logic gates. It seems confusing to design huge digital circuits by logic gates. A procedure will be presented in this paper to design digital circuits with logic gates by contactor control circuits. This method can be useful for skilled persons in designing contactor control circuits. And it will be beneficial in controlling power circuit in low-noise environments, since it can lead to decrease size and expenses

Abstract: The deficiency in the antero-inferior wall of the bony part of external auditory canal (EAC) closes by 5 years of age but if it persists beyond that age it is called foramen Tympanicum. Depending on the population studied, persistence of this foramen has been seen in 0-67% of adult crania. Review of literature revealed that no data was available in North Indian population; therefore the present study is being undertaken. 30 adult human crania were examined and the presence of foramen Tympanicum was noted. The side to which it belonged to, its shape and size were observed. Out of 30 adult human crania seen, foramen Tympanicum was present in 9 crania. It was observed unilaterally in 4 crania and bilaterally in 5. Although different shapes of the foramen like pin point, pin head, irregular and U shape were observed but in majority of cases it was irregular shaped. This study revealed that about 30% of North Indian adult human crania have foramen Tympanicum. Persistent foramen Tympanicum in the adult life may be involved in different abnormalities of the EAC and may lead to otological complications. Therefore, ENT surgeons should be aware of persistent foramen Tympanicum and keep it as one of the possible diagnoses while dealing with patients presenting with otological complications. Also the surgeons should be careful while performing endoscopy of Temporomandibular Joint (TMJ) so that accidental damage of TMJ can be prevented
