Ebook "Spin–orbit coupling effects in two-dimensional electron and hole systems" describes spin-orbit coupling effects in quasi-two-dimensional electron and hole systems. The first part provides a general introduction to the electronic structure of quasi-two-dimensional systems with a particular focus on group-theoretical methods. The main part of the monograph is devoted to spin-orbit coupling phenomena at zero and nonzero magnetic fields.

The purpose of the implement development was to cover more filed in a single pass for reducing the operational time, collect the uprooted residues and to leave it in one end of the ground. Spin groomer designed by using a “solid work 2018 software” and developed in a workshop. Major component of the developed implement is Mainframe, 3-point hitch, circular wheel, pegs and rake.

We study the S=1 anisotropic antiferomagnetic Heisenberg model on a square lattice for all temperatures using the Popov-Fedotov representation of spin operators. In this representation the constraint of single particle site occupation is rigorously fulfilled by introducing an imaginary valued chemical potential.

The cost of fuel and the effect of emission of gases from the burnt fuel into the atmosphere, this necessitated the use of the abundant solar energy from the sun as a source of power to drive a sprayer The Photovoltaic (PV) panel of 6 V, 5 W capacity configured to trap and convert the sun’s energy into the useful power was used to perform the work of spraying. Solar PV Panel was used for operating the sprayer and for charging a battery. The motor was used to regulate spraying liquid from the sprayer tank (5 lit.) and spray it through spinning disc nozzle.

The effective and modern management of competence development, which represents a distinguishing key-factor in future Smart Cities, cannot be limited to the Learning Management exclusively, but rather be inclusive of aspects pertaining to Human Capital and Performance Management in a holistic vision that encompasses not only the sphere of operations but also the tactical and strategic levels. In particular, organizations need solutions that especially integrate Learning Management, Performance Management, and Human Resource Management (HRM).

We study the magnetic ordered phases of the spin-1/2 Heisenberg antiferromagnetic model with nearest J1 and next nearest neighbor J2 exchange interactions on the square lattice using fermionic representation of spin operators within Popov-Fedotov approach.The unphysical states are eliminated on each site by introducing an imaginary chemical potential. Working in local coordinate system for every site we investigate the different ordered phases in dependence on exchange parameters. At T = 0 we recover the conventional spin wave results.

A lathe is a machine tool which spins a block of material to perform various operations such as cutting, Turning, Facing, Threading, sanding, knurling, drilling, or deformation such as metal spinning with tools that are applied to the work piece to create an object which has symmetry about an axis of rotation .Lathe Machine: • The term Centre Lathe is derived from the fact that in its operation the lathe holds a piece of material between two rigid supports called centres, or by some other device such as a chuck or faceplate which revolves about the centre line of the lathe. .Lathe...

We assume that the manifold with boundary, X, has a SpinC -structure with spinor bundle S Along the boundary, this structure agrees with the /. structure defined by an infinite order, integrable, almost complex structure and the metric is K¨hler. In this case the SpinC -Dirac operator . agrees with a ¯ ¯ ∂ + ∂ ∗ along the boundary. The induced CR-structure on bX is integrable and either strictly pseudoconvex or strictly pseudoconcave.
