TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Susan and Joe of Omaha‚ Nebraska are trying to deal with the resent diagnoses of their two and a half year old girl Sophie with an Autism Spectrum Disorder. After coming to terms with their initial shock and grief they went to their doctor for answers. Some of their questions were‚ what causes autism‚ why Sophie‚ are there any cures and what can they do to help her become the most developed woman she can be? Like many other parents had heard before them they received vague and inadequate answers

Background of the study Since the 1980’s‚ we have gained a better understanding of the broad diagnostic category that includes autism and autism-like disorders. Autistic Disorder (autism) is now believed to represent only one part of a clinical spectrum or group of disorders collectively termed pervasive developmental disorders. What is Autism? Autism is a neurobehavioral syndrome caused by a dysfunction of the central nervous system that leads to disordered development. According to the Diagnostic

Ideas about the solar system Our understanding of the solar system has changed over many centuries. Scientists such as Ptolemy‚ Copernicus and Galileo added their ideas to our changing understanding. We observe the universe using a variety of equipment‚ from telescopes to orbiters and landers. Models of the solar system The planets and the Sun orbit the Earth in Ptolemy’s model. Our understanding of the universe has changed over time. Different civilisations have created different models to

In addition‚ mechanical waves can be transverse and/or longitudinal‚ while electromagnetic waves are always transverse. Furthermore‚ electromagnetic waves could be specified into several types‚ which in other words is called the ‘Electromagnetic Spectrum’. Hence‚ those waves are scaled within a range from the lowest frequency with a long wavelength to the highest frequency with a short wavelength. In a chronologic order‚ those waves are: radio waves‚ microwaves‚ infrared‚ visible light‚ ultra violet

vocabulary used in x-rays. Second I will tell why this advance was important and how it still impacts us today. Radioactivity is the spontaneous breakdown of an atom by emission of particles and/or radiation. Since then‚ any element that spontaneously emits radiation is said to be radioactive. The definition of radiation is the emission and transmission of energy through space in the form of waves. A wave can be thought of as a vibrating disturbance by which energy is transmitted. Waves are characterized

Two Australian studies researched teacher attitudes towards inclusion of students on the autism spectrum. A quantitative study (Hay & Win‚ 2012) with teachers (n=81) and students with High Functioning Autism Spectrum disorder (n=32) in one particular mainstream school and a qualitative study (Soto-Chotiman et al.‚ 2012) with 12 Western Australian primary school teachers who had recent experience of teaching
