Internally-balanced Magnetic Unit (IB Magnet) has been developed as a fundamental technique of wall climbing robots. This unit comprises of a permanent magnet which generates a strong sticking force, and a spring unit which cancels the internal force so that the unit can provide easy sticking and releasing actions. In this paper, the authors aim to enlarge usefulness of IB Magnet by several app...

A common problem for elliptically polarizing undulators (EPUs) is that the magnetic forces give a mechanical deflection in the magnet holder construction when changing the undulator phase. Gluing horizontally and vertically magnetized blocks together can increase the mechanical stability of the magnet holders. The gluing process of pairs of magnetized magnet blocks is time-consuming, expensive ...

BACKGROUND The superconducting cyclotron is of great importance to treat cancer parts of the body. To reduce the operation costs, a superconducting magnet system for the 250 MeV proton cyclotron was designed to confirm the feasibility of the superconducting cyclotron. FINDINGS The superconducting magnet system consists of a pair of split coils, the cryostat and a pair of binary high temperatu...

Is there a difference in the level of job satisfaction among clinical nurses employed at magnet versus nonmagnet hospitals, and is it linked to nurse executive leadership? To answer these questions, 305 clinical nurses employed at magnet and nonmagnet hospitals rated their perceptions of job satisfaction while 16 leaders from the same hospitals were interviewed for their perception of their rol...

This study looked at the effect of an external magnet on the biodistribution of magnetoliposomes intravenously administrated in mice (8 mg iron/kg) with and without induced acute inflammation. Our results showed that due to enhanced vascular permeability, magnetoliposomes accumulated at the site of inflammation in the absence of an external magnetic field, but the amount of iron present increas...

Magnetic flux measurements of a toroidal magnet revealed a concave-shaped field distribution with a single minimum and a null field along the axis of the torus at the point where the field reversed. The non-linear magnetic field of the toroidal magnet perpendicular to the Ag2O-doped superconducting disc sample with trapped magnetic flux distorted the field line distribution. As a result, the in...

We consider three mechanisms of hysteresis phenomena in alternating magnetic field: the domain-wall motion in a random medium, the nucleation, and the retardation of magnetization due to slow ~critical! fluctuations. We construct a quantitative theory for all these processes. The hysteresis is characterized by two dynamic threshold fields, a coercive field and the so-called reversal field. Thei...

This paper presents the stability enhancement of four parallel-operated offshore Wind Turbine Generators (WTGs) is connected to an onshore power system using a Static Synchronous Compensator (STATCOM). The operating characteristics of each of the four WTGs are simulated by wind permanent magnet synchronous generator while the onshore power system is simulated by a Synchronous Generator (SG) fed...

Liposomal magnetofection is the most powerful nonviral method for the nucleic acid delivery into the cultured cancer cells and widely used for in vitro applications. Use of the static magnetic field condition may result in non-uniform distribution of aggregate complexes on the surface of cultured cells. To prevent this, we developed the new device which allows to concentrate aggregate complexes...
