Soybean is the main crop grown in Brazil and important to quantify capacity of increase yield by production intensification management. This study aims gap agricultural efficiency (AE) for soybean Central Cerrado biome, Brazil. Yield management (YGMG) water deficit (YGWD) AE climate (CE) were calculated based on potential (PoY), attainable (AtY) actual (AcY) yields. Potential yields AtY simulat...

Gap junctions, strongly implicated as channels for direct cell-to-cell communication, have been isolated from rat liver in high yield and purity. These gap junction fractions contain few morphologically recognizable contaminants, but NaDodSO4/polyacrylamide gel electrophoresis reveals a number of polypeptides. With the exception of a nonjunctional component of Mr 38,000 and some poorly soluble ...

Many low dimensional spin systems with a dimerized or ladder-like antiferromagnetic exchange coupling have a gapped excitation spectrum with magnetic bound states within the spin gap. For spin ladders with an even number of legs the existence of spin gaps and within the t-J model a tendency toward superconductivity with d-wave symmetry is predicted. In the following we will characterize the spi...
