what you can collect can be complicated. The rock collector will learn quite a bit of petrology‚ mineralogy and geology in their search. The most definitive characteristics of a rock or a mineral is its hardness‚ which you can determine by comparing it against the standardized Mohs Scale of Hardness. Many states regulate the collection of some rocks and minerals‚ even on public lands‚ so it is advisable to read up on local news before prospecting. Rock and mineral collecting is prohibited in national

STRENGTHENING OF METALS There are 4 major ways to strengthen metals‚ and all work because they make dislocation motion more difficult. They also reduce the ductility: 1) Cold work (Strain Hardening) 2) Reduce grain size (Strengthening by Grain Size Reduction) 3) Add other elements in solid solution (Solid Solution Strengthening) 4) Add second phase particles (Precipitation or Age Hardening) • These mechanisms may be combined. • For example‚ the world’s strongest structural material (with

We took drops of the water and dropped them very carefully and as neatly as we could on to strips that measured the levels of total chlorine‚ free chlorine‚ total hardness‚ total alkalinity‚ and pH. Waiting about 15-20 seconds‚ we recorded the results and compared them by color on charts and wrote down our findings on what the water contained on that testing day. Besides recording with physical tests we also did visual

1 INTRODUCTION In recent years‚ there has been rapid growth in the number of Fast Dissolving / Disintegrating Tablet (FDT) product on the market. Fast Dissolving Tablets are solid tablets and designed to dissolve/disintegrate in the patient’s mouth within a few second or minutes‚ without the need to drink or chew. However‚ the fear of taking solid tablets and the risk of choking for certain patient populations still exist despite their short disintegration/dissolution times. However‚ some

Prolonged defects to the crystal lattice‚ like grain boundaries‚ obstructs flow of the matter under applied stress‚ increasing its hardness.[7] The reddish-brownish color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells; the difference of energy between the shells corresponds to orange light. Copper is located in period 4‚ group
