Quantum mechanics is a theory that describes the behavior of particles in microscopic world. If stock index can be considered an object on macro scale, then every micro-scale. The price analogous to being particle. This study aimed obtain density distribution returns. Modeling returns using Schrodinger equation model with assumption particle good delta potential function so as known. calculate ...

A model of the grain surface chemistry involving the accretion of atoms of two different elements, X and Y, and their reactions to form species X2, XY, and Y2 was examined for a wide range of choices for the values of its three free parameters – the accretion rate of X and Y, the desorption rate of X and the grain surface sweeping time of Y, all considered relative to the grain surface sweeping...

Background and Objectives: Lactobacillus delbrueckii ssp bulgaricus is widely used in dairy industries as a starter for yogurt production. This study was designed using response surface methodology (RSM) in 12 batch pH-controlled cultures of Lactobacillus delbrueckii sub-ssp. bulgaricus for determining the effect of temperature and pH on the biomass production of a native strain of L. bulgaricu...

West Africa is vulnerable to the effects of climate change. This paper analyzed the impacts of climate change on economic growth in Anglophone West Africa with similar background, during the periods 1969-2016. Five growth model equations have been developed to incorporate climate change variables into the model. Panel data estimations such as the fixed effect model, random effect model and Haus...

What is the optimal rate of new housing supply? We answer this question with a simple model supply where choice variable lot sales. This informed by cost-side assumptions static equilibrium but allows for demand home-buying to vary over time. It differs from models production assuming that landowners hold land assets are sold in asset markets create supply. Landowners maximise present value the...
