Abstract
A Monowave synthetic route for the production of Palladium nanoparticles using Gum karaya(GK) is examined for in vitro cytotoxic efficacy against MCF-7. The present work proves the influence of gum karaya composition on the size and morphology of the produced Palladium nanoparticles. The biosynthetic method is quick, simple and easily synthesized and color changes observed in Ultraviolet and visible spectroscopy. Subsequently, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and Transmission electron microscopy (TEM) analyses were employed to characterize the as synthesized GKPdNP. The XRD investigation confirmed the presence of Pd (0) nanoparticles and interactions between the bio degradable compounds of the Gum and the produced GKPdNP were confirmed by the FTIR spectra. TEM images demonstrated that the nanoparticles has a size distribution of 3±2 nm. Moreover, the anticancer activity of the GKPdNP was tested against MCF-7 strains. All synthesized Pd nanoparticles exhibited good antioxidant activity.

Abstract
Gabriel Garcia Marquez is a well known writer of Latin America, who elevated Magic-realism through his works. Gabriel Garcia Marquez is one among the Big Four, who is closely associated with. Love in the Time of Cholera is one of the novels but a romantic novel. This novel gives a different definition for love which is elevated. The love varies at different stages and ages. The narrator also represents different shades of love which has been described in this novel. This paper discusses the love in different perspective through different shades at different stages of life.
Conversion of a Conventional Lathe Machine into a “Semi Automatic CNC Machine”

Abstract
Turning, milling, and drilling, among other operations, are performed on conventional lathes in small workshops or industries. These operations are being performed by new modern technologies such as computer software, hardware, and firm wares in industries on a daily basis. CNC machines are required for greater accuracy and superior finishing. As a result, CNC machines are becoming more important these days. This is beneficial to modernised industrialization. As a result, we must use retrofitting to convert our traditional lathe into a semi-automatic CNC machine for this modernization. As a result, this research paper investigates how to retrofit a conventional lathe to become a semi-automatic CNC machine. It is used for this purpose by replacing and adding some parts to a conventional lathe.
Implementation Of Magnetism In Material Handling System

Abstract
The project focuses on the design and production of a ground floor crane fitted with a load locking unit at any level as a special feature, to address the problem of failure due to a fixed load. The mobile crane is designed to carry a maximum load of about 5 kg, and a counterweight of 50 kg. The materials used are; sheet metal, profile bars, bolts, nuts, metal rolls etc. Processing procedures include cutting, filling, welding and assembling. For permanent contact, the arc welding process was used. As mentioned earlier, a ground floor crane gains its value in the transport of heavy machine parts inside and outside the workspace. It can also be used to load and unload machine parts onto trucks.
