A quaternionic version of the Calabi problem on the MongeAmpère equation is introduced, namely a quaternionic MongeAmpère equation on a compact hypercomplex manifold with an HKT-metric. The equation is non-linear elliptic of second order. For a hypercomplex manifold with holonomy in SL(n,H), uniqueness (up to a constant) of a solution is proven, as well as the zero order a priori estimate. The ...

among abiotic stresses, salinity has been increasing over the time for many reasons like using chemical fertilizers, global warming and rising sea levels. under salinity stress, the loss of water availability, toxicity of na+ and ion imbalance directly reduces carbon fixation and biomass production in plants. k+ is a major agent that can counteract na+ stresses, thus the potential of plants to ...

BACKGROUND  Currently, malaria elimination efforts are ongoing in several locations across Southeast Asia,  including in Kayin State (also known as Karen State), Myanmar . This paper describes the community engagement efforts for a pilot malaria elimination project, the challenges encountered and lessons learnt. METHODS  Between May 2013 and June 2015, a study on targeted malaria elimination ...

1. Mirror symmetry Superstring theory and conformal eld theory has developed and was connected with algebraic geometry in the late 80's. The mirror symmetry, which implies a kind of symmetry of moduli space of Calabi-Yau varieties, is one of the most striking blows from superconformal eld theory. Since there are numerous papers available in this subject now, we will just follow the story and re...

The natriuretic effects of atrial peptide hormones have been attributed, at least in part, to their stimulation of guanylate cyclase activity in renal cell membranes. The effects of atrial natriuretic factor (ANF) on stimulation of cyclic guanosine monophosphate (cGMP) and cyclic adenosine monophosphate (cAMP) accumulation were investigated in cloned human kidney tumor (hKT) cells and parent ce...

The components outage of an energy system weakens its operation probability, which can affect the sizing that system. An optimal framework is presented for autonomous hybrid photovoltaic/hydrokinetic/fuel cell (PV/HKT/FC) with hydrogen storage to supply annual load demand forced rate (FOR) clean production resources based on real environmental information such as irradiance, temperature, and wa...
