Analysis of Determinants of Entrepreneurial Intentions among Construction Workers  [PDF]
R. Raghunath Reddy, Muddu Vinay, P. Venkateswarlu
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.92022
Abstract:

The Ajzen’s [1] Theory of Planned Behaviour was applied to study the entrepreneurial intentions of the construction workers. The effects of the TPB variables, gender and age on the EI were examined using the statistical tool of multiple linear regression and analysis of variance. The results have indicated that all the three TPB variables such as Attitude towards entrepreneurship, Subjective Norm and Perceived Behaviour Control had significant affect and were the strongest predictors to become entrepreneur. It was evident that females have shown lesser attitude and perceived behavior control than males to become entrepreneurs. Among the respondents, people of 40 and above age have shown inclination to become entrepreneurs. There is a need for the governments to recognize the unorganized construction sector and provide some basic education in strengthening their entrepreneurial skills and enhance their confidence to become better entrepreneurs.

LRS Bianchi Type-I Inflationary String Cosmological Model in Brans-Dicke Theory of Gravitation
R. Venkateswarlu,J. Satish
Journal of Gravity , 2014, DOI: 10.1155/2014/909374
Abstract: We investigate locally rotational symmetric (LRS) Bianchi type I space time coupled with scalar field. String cosmological models generated by a cloud of strings with particles attached to them are studied in the Brans-Dicke theory. We assume that the expansion scalar is proportional to the shear scalar and also power law ansatz for scalar field. The physical behavior of the resulting model is discussed through different parameters. 1. Introduction It is believed that the early universe evolved through some phase transitions, thereby yielding a vacuum energy density which at present is at least 118 orders of magnitudes smaller than in the Planck time [1]. Such a discrepancy between theoretical expectations and empirical observations constitutes a fundamental problem in the interface uniting astrophysics, particle physics, and cosmology. The recent observational evidence for an accelerated state of the present universe, obtained from distant SNe Ia (Perlmutter et al. [2]; Riess et al. [3]), gave strong support to search for alternative cosmologies. Thus, the state of affairs has stimulated the interest in more general models containing an extra component describing dark energy and simultaneously accounting for the present accelerated stage of the universe. The isotropic models are considered to be the most suitable to study large scale structure of the universe. However, it is believed that the early universe may not have been exactly uniform. This prediction motivates us to describe the early stages of the universe with the models having anisotropic background. Thus, it would be worthwhile to explore anisotropic models in the context of modified theories of gravity. Among the various modifications of general relativity (GR), the Brans-Dicke (BD) theory of gravity [4] is a well-known example of a scalar tensor theory in which the gravitational interaction involves a scalar field and the metric tensor. One extra parameter is used in this theory which satisfies the equation given by where is known as BD scalar field while is the trace of the matter energy-momentum tensor. It is mentioned here that the general relativity is recovered in the limiting case . Thus we can compare our results with experimental tests for significantly large value of . The majority of popular cosmological models, including all the ones referred to above, use the cosmological principle; that is, they assume that the universe is homogeneous and isotropic. On the other hand, there are hints in the CMB temperature anisotropy studies that suggest that the assumption of statistical
Influence of Specialization on Entrepreneurial Intentions of the Students Pursuing Management Program  [PDF]
Vivek Ranga, R. Raghunath Reddy, Deepal N. Perera, P. Venkateswarlu
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.92025
Abstract:
This paper was conceptualized with an objective to ascertain the entrepreneurial intentions amongst the students pursuing management program and to assess the influence of respective specialization such as HR, Operations, Finance and Marketing on the entrepreneurial intentions. Ajzen’s [1] Theory of Planned Behaviour was applied to explicate the behavioural intentions. The results indicated that Personal Attitude and Perceived Behaviour Control had significant influence on the entrepreneurial intentions while Subjective Norms did not have any influence. It was identified that overall specialization had no significant influence on the entrepreneurial intentions. However, the students who have taken Marketing as their domain for Specialization in their management program have shown interest to choose entrepreneurship as their career with complete knowledge and larger intent to have control on their business comparatively followed by the students who have taken Finance as specialization. Students of HR and Operations specialization were identified to be lowest in having entrepreneurial intentions.
Tetracycline induced tooth discoloration
Venkateswarlu M,Naga Sailaja R
Indian Journal of Dental Advancements , 2011,
Abstract: Teeth can get discolored due to various factors, both intrinsic and extrinsic. Many chemical substances has the potential to cross placental barrier and affect the mineralization of teeth during their formative stage. Tetracyclines are a group of drugs which can discolor teeth permanently. Due to global awareness among health professionals prescription of tetracyclines and subsequent discoloration has become rare and one such case of discoloration of teeth due to administration of tetracyclines is reported here and discussed in detail.
Finite element simulation of deep drawing of aluminium alloy sheets at elevated temperatures
G. Venkateswarlu,M. J. Davidson,G. R. N. Tagore
Journal of Engineering and Applied Sciences , 2010,
Abstract: More and more automobile companies are going for weight reduction of their vehicles for fuel economy and other features. They have started using more tailored blanked bodies using advanced joining techniques. Such material combinations usually called as “Tailor Welded Blanks” offer better characteristics. However, owing to the presence of different materials their formability is a challenge. The objective of the present study is to determine the effect of blank temperature on forming behavior of sheets and damage factor of such aluminium sheet alloys of 6061 and 7075 at elevated temperatures. An insight into such a study will throw light on the different temperatures required by the above materials when they are made into TWBs. In this present investigation, a series of simulations were carried out on the formability behaviour of cylindrical deep drawing of aluminium alloys in the temperature range 50-500 0 C using DEFORM-2D. The damage factor based on Cockcroft Latham algorithm was taken as the constraint for defect free product. The results show that forming at elevated temperature can yield significant increase in product height, especially for aluminium 7075. The deep drawing of aluminium 6061 alloys show very good formability in a temperature range between 150-2500c and 400-5000c for aluminium 7075. Both the metals gave identical cup heights when drawn at 4750c.

Optical and electrical properties of spray pyrolysis deposited nano-crystalline BiFeO3 films
Annapu Reddy Venkateswarlu,G. D. Varma,R. Nath
AIP Advances , 2011, DOI: 10.1063/1.3662093
Abstract: The nano-crystalline BiFeO3 were prepared under controlled substrate temperature by spray pyrolysis method. Their structural, optical and electrical properties were studied and correlated. A blueshift (Δλ ~ 8.17 nm) in the absorbance peaks was observed in the films with decrease in grain size. The absorption coefficient spectra show defect transitions at 1.9 and 2.3 eV in large grain size films due to oxygen vacancies. The lowest leakage was observed in smaller grain size (< 20 nm) films due to negligible oxygen vacancies, smooth surface roughness and large energy bang gap. The Poole-Frankel conduction mechanism has been found to be the predominant mechanism for the leakage current.
A Hybrid Trajectory Clustering for Predicting User Navigation
Hazarath Munaga,J. V. R. Murthy,N. B. Venkateswarlu
Computer Science , 2011,
Abstract: Wireless sensor networks (WSNs) suffers from the hot spot problem where the sensor nodes closest to the base station are need to relay more packet than the nodes farther away from the base station. Thus, lifetime of sensory network depends on these closest nodes. Clustering methods are used to extend the lifetime of a wireless sensor network. However, current clustering algorithms usually utilize two techniques; selecting cluster heads with more residual energy, and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster and lengthen the network lifetime. Most of the algorithms use random selection for selecting the cluster heads. Here, we propose a novel trajectory clustering technique for selecting the cluster heads in WSNs. Our algorithm selects the cluster heads based on traffic and rotates periodically. It provides the first trajectory based clustering technique for selecting the cluster heads and to extenuate the hot spot problem by prolonging the network lifetime.
