The following contains a description of the principles and techniques used in a modular operating system being implemented at the National Physical Laboratory. The computer being used is a KDF9 with 32K words of core store and a disc file. The system provides a time-sharing and file handling capacity as well as the usual services to users.
[1] The study of planetary magnetic fields can provide important information on a planet’s interior structure and composition. Here we use numerical dynamo models to demonstrate that it is possible to determine information on a fundamental core property: inner core size, from observations of intense, small-scale radial magnetic flux patches. The inner core size is discernable from the boundary ...
This paper reports the measurement and modelling of magnetic properties of SOMALOY 500, a soft magnetic composite (SMC) material, under different 2D vector magnetisations, such as alternating along one direction, circularly and elliptically rotating in a 2D plane. By using a 2D magnetic property tester, the B-H curves and core losses of the SMC material have been measured with different flux de...
We review current synthetic routes to magnetic iron oxide nanoparticles for biomedical applications. We classify the different approaches used depending on their ability to generate magnetic particles that are either single-core (containing only one magnetic core, i.e. a single domain nanocrystal) or multi-core (containing several magnetic cores, i.e. single domain nanocrystals). The synthesis ...
The collapse of slowly rotating molecular cloud cores threaded by magnetic fields is investigated by high-resolution numerical simulation. Outflow formation in the collapsing cloud cores is also followed. In the models examined, the cloud core and parent cloud rotate rigidly and are initially threaded by a uniform magnetic field. The simulations show that the cloud core collapses along the magn...
we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
background: multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. a rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles.objectives: herein, we report on a simple approach for the synthesis of ma...
