Laws of Thermodynamics Challenge Greenhouse-Gas and CLIMATE- change Hypotheses
Abstract: The greenhouse-gas hypothesis (GGH), i.e., CO2 is the cause of global warming by ~1K from ~1950-2023, is popularly believed to be established scientific truth. It is generally assumed that heat emissions from global fuel combustion are, by comparison, negligible. An application of the Hess-Gibbs 1st law of thermodynamics, however, shows that the enthalpy (H) output from yearly fossil fuel consumption is seven times greater than the H- increase of hypothetical …

DESIGN OF TRAFFIC SIGNAL CONTROL SYSTEM AT ORLU JUNCTION, IHIALA, ANAMBRA STATE, NIGERIA
Abstract: The vast increase in population results in number of vehicular movement which contributes to volume of traffic at road intersections. This traffic jam is much during festive periods, causing delay which has negative impact to the economy. No one can easily predict the time of journey arrival due to gridlock at intersection on highways. This inefficient traffic movement is caused by absence of traffic control systems. Hence, this study had …
