The carrier state is defined as persistence of HBsAg in the circulation for more than 6 months. It may be lifelong and may be associated with liver damage, varying from minor changes in the nuclei of hepatocytes to chronic hepatitis, cirrhosis, and primary liver cancer. Several risk factors have been identified in relation to the carrier state ...
Communication Systems, Civilian. Simon Haykin, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. II.A.1 Double-Sideband Suppressed-Carrier Modulation. The carrier wave c(t) is completely independent of the information-carrying signal or baseband signal m(t), which means that the transmission of the carrier wave represents a waste of power.
The simplest forms of transport across a membrane are passive. Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane. A concentration gradient is a just a region of space over which the concentration of a substance changes, and substances will ...
May 24, 2012 · These observations firmly establish these proteins as essential components of the MPC. In the mitochondrion, pyruvate is converted into acetyl–coenzyme A (acetyl-CoA) by the pyruvate dehydrogenase (PDH) complex and participates in the synthesis of branched-chain amino acids (BCAAs) in yeast. Acetyl-CoA donates carbon atoms to the citric acid ...
Jan 6, 2015 · The discovery of the photoelectric effect by Heinrich Hertz in 1887 set the foundation for over 125 years of hot carrier science and technology. ... goes far beyond the traditional definition of a ...
