If you canât, you may want to ask if you can have other juices with the medicine. Read the Medication Guide or patient information sheet that comes with your prescription medicine to see if it interacts with grapefruit juice. Some information may advise not to take the drug with grapefruit juice.
Definition - What does Surface Defects mean? Surface defects are the boundaries, or planes, that separate a material into regions, each region having the same crystal structure but different orientations. Surface defects may cause corrosion and coating failure. The presence of surface defects can dramatically change the corrosion resistance and mechanical properties of a material.
Types of Defects Defects may be classified into four categories depending on their dimension: Â¾0D, Point defects: atoms missing or in irregular places in the lattice (vacancies, interstitials, impurities) Â¾1D, Linear defects: groups of atoms in irregular positions (e.g. screw and edge dislocations) Â¾2D, Planar defects: the interfaces between homogeneous regions of the material (grain boundaries, external surfaces) Â¾3D, Volume defects: extended defects (pores, cracks) Introduction To Materials Science, Chapter 4, Imperfections in solids University of Tennessee, Dept. of Materials Science and Engineering 6 Point defects: vacancies & self-interstitials Self-interstitials Vacancy Vacancy - a lattice position that is vacant because the atom is missing. Interstitial - an atom that occupies a place outside the normal lattice position. It may be the same type of atom as the others (self interstitial) or an impurity interstitial atom.
