Continuous generative cosmology based on the Higgs mechanism and general relativity

This paper reveals from the perspectives of particle physics and general relativity that cosmic matter is gradually generated, rather than being created in an instant by the Big Bang. The Higgs mechanism of particle physics is the microscopic mechanism of continuous generation of cosmic matter, dominated by the theory of general relativity on a macroscopic or cosmological level. The Higgs field only exists inside...

A study of the correlation between the soil and air temperature of the Nsukka area, Enugu State

The Nigerian Environmental Climatic Observing Program (NECOP) station in Nsukka collected soil temperature and surface air temperature observations during a three-year period, which served as the basis for this study. To illustrate the interdependencies between the two, data series of the soil temperature and air temperature for the years under consideration (2012-2014) were co-plotted. Microsoft Excel was used to...

Modeling the impact of different wavelengths of sunlight on the performance of a silicon photovoltaic (PV) cell

Previous studies have experimentally investigated the impact of filtered sunlight or monochromatic LEDs on PV cell performance. However, theoretical analyses of wavelength-specific effects remain limited. This work addresses this gap using a 1-D model to investigate the impact of different wavelengths of sunlight on the performance of a silicon PV cell, addressing the limitations of experimental studies. In this work,...
