The purpose of this research paper is to determine those factors that influence the adoption of online banking services in Hyderabad. A theoretical model is provided that conceptualizes and links different factors influencing the adoption of online banking in Hyderabad. A total of 302 respondents in Hyderabad were sampled for responding. Factor analyses and regression technique are employed to study the relationship. The results of the model tested clearly that use of online banking is influenced by channel convenience, perceived risk, security perception, prior internet knowledge and information on online banking. The results also determine that demographic factors also impact significantly on online banking. Finally, this paper suggests that an understanding the factors affecting intention to use internet banking is very important to the practitioners who plan and promote new forms of banking in the current competitive market.

Entrepreneurship is a distinct and crucial factor of production. The spirit of enterprise makes man an entrepreneur. Such a spirit transformed man from a normal to cattle breeder to a settled, agriculturist to a trader and to the industrialist. These entrepreneurs are persons who initiate, organize, manage & control the affairs of business units that combine the factor of production, to supply goods & services, whether the business pertains to agriculture, industry trade or profession. The emergence of entrepreneurs in a society depends to a great extent on the economic, social, religious, cultural and psychological factors prevailing in the society.

Biometric is a tool of identification that has been broadly used in many applications. A biometric identification system is based on physical characteristic. Dental biometrics has emerged as vital biometric information of human being on account of its stability, invariant nature and uniqueness. It utilizes dental photograph and dental radiograph for human identification because it provides information about teeth including tooth contour, relative position of neighboring teeth and shapes of dental work like crown, fillings and bridges. A biometric identification system is based on physical characteristics such as face, fingerprint, palmprint, fingerprint, eyes (iris, retina ) and DNA. However, many of those characteristics are only suitable for ante mortem identification when a person to be identified is still alive. They cannot be used for post mortem identification specially in such cases of decay or severe body damage caused by fire or collision, due to this dental biometrics plays an important role in human identification and post mortem identification. This paper address review of such different techniques used in dental biometrics.

The group B(m,n) satis?es identity relation x^n = 1. Moreover, sinceF_m^n is a verbal subgroup of group F^m generated with word x^n, the group B(m,n) is free in the variety of all n-periodic groups, i.e. all groups, where the identical relationx^n = 1holds. The group B(m,n) is free in the variety of all n-periodical groups and is called free-periodical or free Burnside group of the period n and rank m.

The use of inhibitors for the control of corrosion of metals which are in contact with aggressive environment is an accepted practice. It is needless to point out the importance of cheap, safe inhibitors of corrosion. Plant extracts have become important as an environmentally acceptable, readily available and renewable source for wide range of inhibitors. The inhibition of the corrosion of copper in nitric acid solutions by senesio extract has been studied using chemical and electrochemical techniques. Inhibition was found to increase with increasing concentration of the senesio extract. Senesio extract is a rich source of ingredients which have very high inhibition efficiency. The adsorption of senesio extract on copper surface was found to obey Langmuir adsorption isotherm. The polarization data revealed that senesio extract acts as mixed type inhibitors. The surface morphology was analyzed.

In this paper an attempt is made to highlight and strengthen the inherent role of quantum gravity in cosmology. At any time, the product of cosmic ‘critical density’ and ‘critical Hubble volume’ can be called as the ‘critical mass’ of the evolving universe. By considering the Planck mass as the critical mass connected with big bang, Planck scale critical mass density and Hubble constant can be defined. Proceeding further, it can be suggested that, during evolution, cosmic thermal energy density may be directly proportional to critical mass-energy density. Observed redshift can be reinterpreted as a cosmological light emission phenomenon connected with cosmologically reinforcing hydrogen atom. To understand the ground reality of cosmic rate of expansion, accuracy of the current methods of estimating the magnitudes of current Hubble’s constant and current CMBR temperature must be improved.

Lots of research and developments have been made in accepting the behavior of engineering materials when machining at higher cutting conditions. Developments attained from research and development activities in this area have particularly enhanced the machining of difficult-to-cut titanium alloys that have traditionally exhibited low machinability due to poor thermal conductivity, high strength at elevated temperature, resistance to wear and chemical degradation, etc. These alloys are used extensively where the strength-to-weight ratio and corrosion resistance are of the utmost significance. Even though there have been prodigious developments in the development of cutting tool materials which have significantly improved the machinability of a large number of metallic materials, including cast irons, steels and some high temperature alloys such as nickel-based alloys, no equivalent development has been made for cutting titanium alloys due primarily to their abnormal characteristics. A worthy accepting of the cutting tool materials, cutting conditions and functionality of the machined component will lead to efficient and economic machining of titanium base super alloys. This paper evaluation the main problems associated with the machining of titanium as well as tool wear, the mechanisms responsible for tool failure. Step growth in productivity, hence lower manufacturing cost, without contrary result on the surface finish and surface integrity of the machined component. It was found that the straight tungsten carbide (WC/Co) cutting utensils remain to maintain their superiority in almost all machining processes of titanium alloys, whilst CVD coated carbides and ceramics have not replaced cemented carbides due to their reactivity with titanium and their relatively low fracture toughness as well as the poor thermal conductivity of most ceramics. Cubic Nitride Boron (CBN) outfits are also normally used for machining harder alloys such as titanium and nickel alloys. The implements are expected to endure the heat and pressure developed when machining at higher cutting conditions because of their high hardness and melting point. An effort has been made to debate special machining methods, such as Rotary cutting, High pressure coolant delivery, Cryogenic cooling, Minimum Quantity Lubrication and the use of ledge tools, which have shown some success in the machining of titanium alloys.

A separation cordial labeling of graph is a bijection f from to such that each edge uv is assigned the label 1 if ) is an odd number and label 0 if is an even number. Then the number of edges labeled 0 and the number of edges labeled 1 differ by at most 1. A graph has a separation cordial labeling, then it is called separation cordial graph. Here, the bistar the splitting graphs of and , the shadow graph of and square graph of are discussed and found to be separation cordial.

A tree T is called starlike [2], if it contains a vertex v for which deg (v) ? 3 and all other vertices of T have degree 1 or 2. If deg (v) = k, the starlike tree T is k – branched and T – v has k components, each of which are trees. In this paper, we characterize the 3 – branched starlike spanning trees of a given two dimensional mesh M(m, n) m, n ? 3 and then find its number with junction vertex [2] of degree 3.

A point determining graph is defined to be a graph in which distinct non adjacent points have distinct neighborhoods. If in addition any two distinct points have distinct closed neighborhoods, it is called point distinguishing graph. A graph G is said to be one point determining, if for any two distinct vertices v_1 and v_2 ?N(v?_1)and? N(v?_2) have at most one vertex in common. A graph G is said to be two point distinguishing if for any two distinct vertices v_1 and? v?_2, the closed neighborhood ? N[v?_1] and ? N[v?_2] , have at most two vertices in common. Here we focus on some properties of one point determining and two point distinguish- ing graphs.
