A one-dimensional reaction-diffusion model consisting of two species of particles and vacancies on a ring is introduced. The number of particles in one species is conserved while in the other species it can fluctuate because of creation and annihilation of particles. It has been shown that the model undergoes a continuous phase transition from a phase where the currents of different species of ...

Highlights Temperature and air movement in the naturally ventilated barns correlated to ambient conditions. Manure N-P-K values related solids distribution manure storage. Ammonia combined sulfur concentrations increased with closer proximity surface. Influences of properties, airflow conditions, barn design, management were evident for gas concentrations. Abstract . There is a lack data descri...

This question has always been put forward in the mind of curious people why some countries have developed termed in spite of very few natural resources and facilities while other countries have not developed in spite of having more suitable resources and facilities.
