the sustainability of farming system (sofs) is considered to be an important principle in a broad concept of sustainable agriculture. variables affecting sofs include alternate crop farming (using nitrogen-fixing plants as alternate crops), utilizing farm animal manure, using plants and crop residues back into the soil system, and utilizing a variety of protective plowing schemes. overuse and p...
Innervation of the neuromuscular junction (nmj) affects the stability of acetylcholine receptors (AChRs). A neural factor that could affect AChR stabilization was studied using cultured muscle cells since they express two distinct populations of AChRs similar to those seen at the nmjs of denervated muscle. These two AChR populations are (in a ratio of 9 to 1) a rapidly degrading population (Rr)...
This study describes a 12-bit, 4K2K 60-fps CMOS image sensor capable of reducing the pixel readout rate without degrading resolution of the output images. The data reduction is done by a novel “stagger-laced” scan, which reduces the data rate by half by alternate readout of two sets of horizontal pixel pairs arranged in two complementary checkerboard patterns. For the 12-bit, 60-fps readout of ...
Vinblastine is shown to induce pronuclear fusion failure in conjugating Tetrahymena thermophila. In this alternate conjugational pathway gametic pronuclei are exchanged between conjugants but do not fuse. Each pronucleus undergoes one mitotic division to produce a new macro- and micronucleus. Genetic consequences of pronuclear fusion failure include the following: (1) the progeny are whole geno...
The title compound, C(27)H(43)ClO, is a steroid derivative composed of a saturated carbon fused-ring framework with an alkyl side chain. The A and C rings have chair conformations and the B and D rings assume half-chair conformations. The cholesterol side chain is fully extended with a gauche, trans conformation of the terminal methyl groups. In the crystal structure, the molecules are aligned ...
