Arsenic threat reaching global dimensions

Dengue: global health threat.

Dengue: Global Threat.

Dengue is a mosquito-borne viral disease, which is currently an expanding global problem. Four closely related dengue serotypes cause the disease, which ranges from asymptomatic infection to undifferentiated fever, dengue fever (DF), and dengue hemorrhagic fever (DHF). DHF is characterized by fever, bleeding diathesis, and a tendency to develop a potentially fatal shock syndrome. Dengue infecti...

Gorenstein global dimensions for Hopf algebra actions

Let $H$ be a Hopf algebra and $A$ an $H$-bimodule algebra‎. ‎In this paper‎, ‎we investigate Gorenstein global dimensions for Hopf‎ ‎algebras and twisted smash product algebras $Astar H$‎. ‎Results from‎ ‎the literature are generalized‎. 

Zika – an Emerging Global Threat

Zika virus disease (Zika) is a new emerging mosquito borne illness, transmitted by the bite of an infected mosquito especially Aedes aegypti. The infection, known as Zika fever often causes no or only mild symptoms which include fever, rash, joint pain, and conjunctivitis, which may last up to a week [1]. The Pan American Health Organization (PAHO) confirmed the first Zika virus infection in Br...

Global Gorenstein Dimensions

In this paper, we prove that the global Gorenstein projective dimension of a ring R is equal to the global Gorenstein injective dimension of R, and that the global Gorenstein flat dimension of R is smaller than the common value of the terms of this equality.
