Authors : Haydar U. Zaman,Ruhul A. Khan,


Thermoplastic polypropylene (PP) composites containing 10, 20, 30, and 40% wt% of calotropis gigantea fiber (CGF) were created in the current study using compression molding in the presence of alkaline pretreated CGF (ACGF), which was modified with aminopropyltrimethoxy silane (ACGF/AS) and tetramethoxyorthosilicate (ACGF/TS) as a silane coupling agent. The composites' CGF content has been...

Effect of Naturally Occurring Hematite on Mechanical and Electrical Properties on Natural Rubber Composites
Authors : Franklin Anaele Opara,Chima Kenneth Oguzie,Henry Chinedu Obasi, ,Simeon Chukwudozie Nwanonenyi,,Chukwuemeka Emmanuel Odoala, ,Magdalene Nkeiru Akanbi,


The effect of naturally occurring hematite (α-Fe2O3) particles on composites based on natural rubber (NR) was investigated. The matrix was composed of 100g of NR, whereas α-Fe2O3 particles obtained from Kastina State in Nigeria were loaded in varying amounts of 3g, 5g and 7g. The compounding of the constituent materials was achieved with the aid of a two-roll mill in line with ASTM D15-627. The...

Laser Plasma Interaction in Laser-based Accelerators with Self-focusing of Laser
Authors : Sanhita Paul,


Extreme light intensities can be produced by high-power lasers, but the requirement for huge beam diameters to prevent damage to optical components prevents future development. Plasma can support extremely brilliant radiation and can be used to create and manipulate light without causing damage to solid materials. In order to create extremely high acceleration gradients for accelerators,...

On Optimization of Manufacturing of Field-effect Transistors in the Framework of a Switch to Increase their Integration rate-On Influence Mismatch-induced Stress
Authors : E.L. Pankratov,


In this article, we describe a method to increase the density of field-effect transistors in the framework of an absorptive single pole single-throw switch. In the framework of the approach, we consider the manufacturing of inverters in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that, the...

Thermodynamic Properties and Drying Kinetics of Potato Slices using Hot Air Drying
Authors : N.J. Edeani,K.A. Eze ,M.M. Chukwu ,


Potatoes are important foodstuffs all over the world. The influence of slice thickness and varying temperatures on potatoes was studied during oven drying. This work on thin layer drying was carried out between 60oC and 80oC at different slice thicknesses of 0.4cm 0.6cm and 0.8cm. The sliced samples were pre-treated with 0.5% sodium meta bisulphite solution for five minutes and oven-dried at...

Development of Twin Model for the Bioremediation of Crude Oil Sludge Contaminated Soil
Authors : Chika Onu ,C.I.O. Kamalu,J.C. Obijaku,M.S. Nwakaudu,E.E. Anyanwu,


Twin mathematical models were developed for substrate reduction and biomass increase respectively. The analytical solution of the twin models gave a sigmoidal substrate decline curve and a sigmoidal biomass increase curve respectively. The developed models aided the monitoring and prediction of crude oil sludge degradation in soil by the activities of stimulated biomass. The solution of the twin...

Brain Tumor Classification from Magnetic Resonance Images using Routing Agreement Algorithm
Authors : K. Saranya,S. Sumathi,


Cancer is the world's most common disease and the second biggest cause of mortality among humans. Brain tumors are protracted forms of cancer due to their aggressive nature, varied features, and dismal relative survival. Pretreatment, segmentation, and detection of infected tumor regions utilizing magnetic resonance (MR) images is a big issue, and radiologists or clinical personnel must complete...

Authors : R. Vijay Kumar,K. Prabakaran,K.B. Rajesh,A. Mohamed Musthafa,V. Aroulmoji,


The tight focusing of a double ring-shaped radially polarized sinh Gaussian beam with a cosine phase plate is studied on the basis of the vector diffraction theory. Under a high-NA focusing condition, the strong longitudinal component forms a sharper spot at the focal point for both fundamental mode (R-TEM01*) beams and higher-order, radially polarized mode beams. Due to destructive interference...
