Improvement of Efficiency and Thermal Withstanding Capacity of Single Phase Induction Motor

[Abstract] [Full-Text PDF] [html]

Abstract: In recent days, it has been shown that the mixing of nano fillers to the enamel can tremendously improve the thermal, mechanical and electrical properties of enamel used in motors. Many nano fillers can be added to the enamel used in the motor. In this research work, SiO2 has been used as nano filler. The micro powders of SiO2 were converted into nano powders with the help of ball mill. Various methods were used to augment the particle size of the nano powders. But, for this research, scanning electron microscope (SEM) has been used to augment the particle size of the nano powders. The prepared nano powders of SiO2 were mixed with enamel by using ultrasonic vibrator. The enamel filled with SiO2 nano filler was coated on the windings of the single phase induction motor. The performance analysis of the single phase induction motor was usually done by means of no load test, blocked rotor test and load test. Based on the results obtained from the above tests, the efficiency of the single phase induction motor coated with enamel filled with SiO2 nano filler was increased by 5% when compared to that of the single phase induction motor coated with pure enamel. Heat run test was also carried out on this motor to determine the total loss of energy dissipated as heat.

Geometric Characterization of Cricoid Cartilage in Indian Population for Biomechanical Modeling

[Abstract] [Full-Text PDF] [html]

Abstract: The complex anatomy of the vertebrate larynx shows a steady progression from the simple slit on the floor of the lungfish’s pharynx to the fine-tuned mechanism of the human vocal apparatus. The study was conducted on 50 cricoid cartilages (36 males & 14 females) obtained from unclaimed bodies in the Deptt. of Forensic medicine, LHMC. This study attempts to define and measure some biomechanically important morphometric features of cricoid cartilage which are useful for constructing quantitative biomechanical models of vocal fold vibration and posturing. The dimensions and geometric positions of Cricothyroid (CT) and Cricoarytenoid (CA) facets with respect to the laryngeal framework are biomechanically important, as they contribute to the determination of CT and CA translation rotational dynamics, which are critical for length changes and posturing (abduction and adduction) of vocal cords.

Creating a High Performance Organization with Strategic Organization Culture and Values

[Abstract] [Full-Text PDF] [html]

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.

Cutaneous Manifestations of Diabetes Mellitus in Adult Patients of Telangana Region of South India

[Abstract] [Full-Text PDF] [html]

Abstract: Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Although diabetes mellitus can be asymptomatic, many patients present with wide spectrum of manifestations. The untreated hyperglycemia of diabetes can cause many acute and serious long term complications. DM is frequently associated by a variety of cutaneous manifestations that commonly serve as ports of entry for different microorganisms. Skin manifestations can be associated with both type 1 & type 2 Diabetes and were seen in patients who use insulin as well as those who use oral hypoglycemic agents to control their glucose levels. Early recognition of these skin manifestations assists in early diagnosis and helps to lead towards appropriate treatment for diabetes mellitus patients. Early diagnosis also helps in preventing long-term complications. The present study evaluates the frequency of skin manifestations in 220 diabetic patients of Telangana region of south India. Skin infection (19.35%), itching (12.09%), & skin atrophy (10.48%) are the three most common initial skin manifestations in DM patients. The present study reveals that it took more than 10 years for skin manifestations to appear in 60% of the patients. On the other hand, no patient reported manifestations at 30 or more years since they have been diagnosed with DM. The maximum number of patients who reported skin manifestations was at 17-18 years since the onset of DM diagnosis.

Social and Service Design: the challenges for contemporary India

[Abstract] [Full-Text PDF] [html]

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.

Maximum Power of PV Cells Using Fuzzy Control

[Abstract] [Full-Text PDF] [html]

Abstract: Since 2006, power generation sector faced several obstacles with limited output of Gaza Power Plant and fixed imports from Israel and Egypt. The demand keeps increasing annually while the supply is either fixed or decreased. Thus, there is a need for alternative power sources for emergency cases as hospitals and medical centers. The shortage in electric power, forced hospitals and medical centers to run their own generation units when fuel is available; creating more pollution and noise. This paper proposes replacing diesel generator by solar photovoltaic (PV) cells as a backup system, and a batterybank as a storage system. Such system is expected to: satisfy the load demands, minimize the costs, maximize the utilization of renewable sources, optimize the operation of battery-bank which is used as backup unit, and reduce the environment pollution emissions. This paper proposes a methodology to maximize power of a PV grid connected system by optimizing the performance of the inverter. A fuzzy logic controller is proposed to control a DC/AC inverter that forces the photovoltaic array to deliver its maximal power for any value of solar insolation rapidly. Results shows improvement in the system performance using fuzzy logic control and the PV is capable of feeding the load with the required energy and charges the battery with its demands.

Persistent Foramen Tympanicum: Incidence and Clinical Implication

[Abstract] [Full-Text PDF] [html]

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
