3[degrees]) of PA6 are consistent with previously reports [22, 25, 26], Generally, the [alpha] crystalline phase is thermodynamically stable for PA6 and consists of sheets of hydrogen-bonded chains formed between antiparallel chains, while the [gamma] crystalline phase is meta-stable and consists of random hydrogen bonding between parallel chains [25-27].
11] The three chains form a monomer made up of two globular domains connected by a triple helical structure, which assemble in the cytoplasm into antiparallel dimers, associate laterally into tetramers, and then secret into the extracellular space.
The A chain forms 2 almost antiparallel [alpha]-helices, from A2 to A8 and from A13 to A20.
Five strands ([beta]1: 4-10, [beta]2: 13-20, [beta]5: 41-45, [beta]8: 66-71, and [beta]9: 74-79) formed one antiparallel [beta] sheet except for a parallel pair, [beta]1 and [beta]9, and the other five strands ([beta]3: 22-27, [beta]4: 30-34, [beta]6: 47-54, [beta]7: 57-64, and [beta]10: 82-84) formed another antiparallel [beta] sheet.
The conserved structure of PDZ domains consists on 6 P-strands and 2 a-helices forming a [beta]-sandwich that displays a hydrophobic groove, where C-termini peptides can bind as antiparallel [beta]-strands.
The electron spins at A and B lattice positions are antiparallel to one another, whereas within A and B lattice positions they are parallel to one another.
The most important domain 4 is consists of eight b-sheets that are present in parallel and antiparallel fashion.
Chitosan is less crystalline than chitin due to the specific antiparallel chains of chitosan and their cross linking.
Examples of such organization are the ferromagnetic and anti-ferromagnetic phases in electronic (spin-1/2) systems: the former is characterized by the parallel alignment of adjacent electron spins in a lattice, while the latter exhibits an antiparallel arrangement of the spins.
Power devices under consideration are silicon (Si) IGBT with Si antiparallel diodes, Si IGBT with SiC antiparallel diodes, Si MOSFETs, SiC MOSFETs, and enhancement-mode GaN transistors.
This unipolar PWM converter consists of four IGBT switches with internal antiparallel diodes, two inductors, and three capacitors.
Agonistic behavior was defined as follows: encounter between two pigs that involved physical contact (biting, head-thrusting, ramming, or pushing with the opponents standing in antiparallel position and with both performing bites or knocking), and started with the first physical contact and ended with submissive behavior (escape) being shown by one of the opponents or when both piglets moved away from each other (Langbein and Puppe, 2004; Borberg and Hoy, 2009; Samarakone and Gonyou, 2009; Krauss and Hoy, 2011; Rhim, 2012).
