PERFORMANCE STUDY OF FLEXIBLE PAVEMENTS ON NON EXPANSIVE SOILS

As part of infrastructure development   huge investment is being made on expansion of National highways and important roads across the country.  For improvement of Highways two types of Pavements are commonly used in India viz., Flexible Pavements (Bituminous) and rigid pavements (Concrete). Flexible pavements are widely used in this country from the considerations of economy The performance of Flexible pavements depends largely on properties of original ground on which the pavement rests, the quality of materials used in the construction of various layers of pavement and quality assurance as per relevant specifications. In general any road after construction is basically evaluated by the performance in terms of unevenness index and structural stability over a period of time. The evaluation of these two important parameters will facilitate the clear understanding of performance of various materials used in the construction and to undertake suitable rehabilitation measures if necessary.

PC to PC Transfer of Text, Images Using Visible Light Communication (VLC)

Light Emitting Diodes are assuming a noteworthy part in numerous regions of our everyday life. Aside from transmitting light, these LED\u27s can be used for data transmission utilizing Visible Light Communication (VLC). In this paper, We propose a complete model to transfer text, images from one device to another using Visible light communication, in which transmitter transmits the encrypted data through visible light and the receiver at the receiving end identifies the transmitted data and decrypts it to retrieve the data sent

Changes in the ducts of the glands of the hard palate in reverse smokers

Three hundred fifty-nine cases of stomatitis nicotina were studied in reverse smokers of home made chuttas. One hundred thirty-five biopsies of papular unbilicated lesions of stomatitis nicotina were studied histopathologically. The biopsies were chosen after toluidine blue staining. Mild dysplastic to severe dysplastic changes were seen around the openings of the ducts of the glands. There were three cases of microinvasive carcinoma in the one hundred thirty-five biopsies. Cystic dilatation of the ducts, due to obstruction of the ducts by keratotic plugging, was not seen in stomatitis nicotina lesions but was seen in elderly women who had smoked reverse for more than 4 to 5 decades. The ducts of the glands could probably form a portal of entry for the tobacco pyrolytic products which may act as carcinogenics

Unsteady boundary layer flow of thermophoretic MHD nanofluid past a stretching sheet with space and time dependent internal heat source/sink

In this study we analyze the boundary layer flow of a thermophoretic magnetohydrodynamic dissipative nanofluid over an unsteady stretching sheet in a porous medium with space and time dependent internal heat source/sink. The governing equations are transformed to ordinary differential equations by using similarity transformation. Numerical solutions of these equations are obtained by using the Shooting Technique. The effects of non-dimensional governing parameters on the velocity, temperature, concentration profiles, friction factor, Nusselt and Sherwood numbers are discussed and presented through graphs and tables. Accuracy of the results compared with the existing ones. Excellent agreement is found with earlier studies

Radiation and Soret Effects of MHD Nanofluid Flow over a Moving Vertical Moving Plate in Porous Medium

We analyzed the magneticfiled, radiation and soret effects of a nanofluid flow over a moving vertical plate in porous medium. We considered two types of nanofluids namely Cu-Ethylene glycol, CuO-Ethylene glycol. The governing partial differential equations of the flow are transformed to ordinary differential equations by using similarity transformation and then solved numerically. The effects of non-dimensional governing parameters namely volume fraction of nano particles,  magneticfiled parameter, radiation parameter, soret number, buoyancy parameter and porosity parameter on the flow, temperature and concentration profiles are discussed and presented graphically. Also, the friction factor and Nusselt and Sherwood numbers are discussed and given in tabular form for two nanofluids separately. Keywords: MHD, Radiation, Soret effect, Porous medium, Nanofluid
