China said that the so-called judgment delivered by the "Uyghur Tribunal" is nothing but a political farce staged to curb the development of the Xinjiang Uygur autonomous region and discredit China.
MANILA-The Department of Agriculture (DA) is seeking additional PHP12 billion, on top of the recommended PHP95-billion budget for 2022, to address surmounting food and agriculture global challenges onto the "new world". "We are entering a 'New World' -- the global scale of the 'new normal' as an offshoot of the Covid-19 pandemic -- wherein every country in the world is coping with huge challenges.

Is it possible that we are not alone in the universe, but are just like animals in a zoo to the aliens who are watching us?
The Fisher-Kolmogorov-Petrovsky-Piskunov (Fisher-KPP) equation is one of the prototypical reaction-diffusion equations and is encountered in many areas, primarily in population dynamics. An important consideration for the phenomena modelled by diffusion equations is the length of the diffusive process. In this paper, three definitions of the critical time are given, and bounds are obtained by a careful construction of the upper and lower solutions. The comparison functions satisfy the nonlinear, but linearizable, partial differential equations of Fisher-KPP type. Results of the numerical simul...
