Study of thermoplasmonic properties of gold nanodimer in visible -infrared region of electromagnetic spectrum

In the present study, the heat generation in gold nanodimers when irradiated at their localized surface plasmon resonances is investigated numerically. The theoretical calculations are performed employing the first principal approach to obtain the absorption cross-section of gold nanodimer for different parameter ranges. The heating mechanism is enumerated in terms of its temperature by solving the steady-state heat transfer equation which depends on the absorption cross-section and surface plasmon resonance wavelength. These surface plasmon resonances are quite sensitive to the distance between the dimer and have been tuned from visible to IR range by managing the distance between spheres from 0 to 6nm. The computation of normalized electric field distribution of gold nanodimer under the plasmon resonance has been mapped using boundary element method(BEM) which enables visualization of the local hot spot that plays a significant role in optical heating applications. The work furnishes the basic understanding of the heating mechanism of gold nanodimer which can find application as plasmonic nanoheaters in several branches of science in visible and near-infrared regions of the electromagnetic spectrum.

Study of Age and Gender Predilections amongst the Victims of Burns of Domestic Violence

Background: Human life from conception till death needs some sources of energy or heating mechanism to advance from a day to another in the process of livelihood. From innocent infants falling victims to fires, toddlers to scalds, youth to vitriolage and elders to enmity of a variety of sources or to their own debilitation bring them close to the fire source let them fell a prey to burns. Aim: To observe the age and gender predilections amongst the victims of burns Methods: The study was carried out among 250 victims of burns presented from December 2017 to August 2018 and reported in the Accident and Emergency Department of Mayo Hospital Lahore and filtered in Medicolegal Clinic of King Edward Medical University Lahore. Results: The study revealed maximum involvement of pediatric and geriatric age groups falling victim to burn incidents. In an analysis as a whole almost 84% victims were belonging to these two extremes of ages. Gender disparity showed a slight difference of just 10% showing female preponderance being exposed to burns. Keywords: Burns, Age, Gender, Variation, Disparity

Experiment Regarding Magnetic Fields with Gravity

The ground-based device simulates the potential energy (voltages) between gravity and magnetic seas. The gravity generator (GG) generated currents and voltages on the mesoscopic scale in the vacuum. Gravity interacts to generate electricity in the Earth's direction or the opposite direction by the repulsive magnetic force. A trapped gravity was set to behave as free relativistic quantum particles or fluids, which made it possible to measure the particle position as a function of time. Our result is grounded on a rigorous proof based on numerical and analytic computations, which took it accessible to study the magnetic sea for different initial superposition of positive- negative-gravity spinor state. It might explain the relativistic quantum gravity and the heating mechanism of the Sun.

Experiment Regarding Magnetic Fields with Gravity

We observed the Earth's gravity to produce electricity in the magnetic sea. The gravity generator (GG) generated currents and voltages on the mesoscopic scale when we connected it in the vacuum. Gravity interacts to generate electricity in the Earth’s direction or the opposite direction by the repulsive magnetic force. The ground-based device simulates the potential energy (voltages) between gravity and magnetic seas. The GG increased simulations of gravity quantum effects using different physical set-ups. A trapped gravity was set to behave as free relativistic quantum particles or fluids, which made it possible to measure the particle position as a function of time and study the magnetic sea for different initial superpositions of positive- negative-gravity spinor state. It might explain the relativistic quantum equations, antigravity, and the heating mechanism of the Sun.

DESIGN AND FABRICATION OF SOLAR TUNNEL DRYER FOR COPRA APPLICATION

A semi-cylindrical forced convection type solar tunnel dryer (STD) was designed and commissioned at M/s Miraj Products Pvt. Ltd., Nathdwara for drying processed tobacco. Essentially it is based on the mixed mode with direct and indirect type of heating mechanism i.e. the heated air from different solar flat plate collectors is passed through drying cabinet. At the same time, the drying cabinet absorbs solar energy directly through the transparent walls and roofs. It consists of 16×3.75 m2 area, tunnel equipped with 12 solar flat plate collectors of 2 m2 each propelled with 2 exhaust fans of 1 kW capacity placed on both ends of the tunnel. The dryer was tested at no-load and full-load conditions. During no-load, without flat plate collectors, temperatures inside the dryer were about18-20℃ higher than the ambient temperature during summer day-light, where as in no-load with flat plate collectors, it was about 30℃ higher than the ambient temperature. A batch of processed tobacco of 500 kg with an initial moisture content 138% d.b. were successfully dried in full load condition to have final moisture content of about 8.7% d.b. in 8 h. It has been observed that STD has many other advantages i.e. getting rid of toxicant gas to labours during opening drying due to lime presence in material, avoidance of product expose to fly contamination and dust concentrations etc.
