Nutrafin Carbonate and General Hardness Test Kit $13.99 General Hardness is a measure of all the dissolved salts in the water. This concentration of dissolved salts affects the osmotic regulation systems in fish. In addition, General Hardness influences calcium levels in the blood. The General Hardness should correspond to the original habitat of the species being kept. Carbonate Hardness (commonly called alkalinity) is a measurement of the capacity for water to neutralize an acid, known as the buffering capacity. It is an important component of water chemistry because it helps stabalize water pH. Carbonate Hardness is also an important source of energy for nitrifying bacteria that eliminate ammonia and nitrite. In addtion carbonates are used by plants for photosynthesis when carbon dioxide is absent. |

RC Hagen A7830 Carbonate and Total Hardness Test for Fresh Saltwater $31.06 The Carbonate and General Hardness Test Kit is an easy at home test to ensure that the general and carbonate hardness levels in your aquarium are at a safe level for your fish. Carbonate Hardness (KH) levels need to be tested on a regular basis because they fluctuate over time and can negatively impact the pH balance of the aquarium water. Low Carbonate Hardness will result in poor plant growth. Testing for General Hardness (GH) should be done to determine if the levels of Calcium (Ca) and Magnesium (Mg) are optimal for specific species of fish. The Carbonate and General Hardness Test Kit Features and Benefits:. Use in fresh or saltwater aquariums. Determines if proper levels of magnesium and calcium are present. Proper Carbonate levels ensure maximum plant growth. Provides a healthy living environment for your fish. |

Lawsonite (Hydrous Calcium Aluminium) $68.51 High Quality Content by WIKIPEDIA articles Lawsonite is a hydrous calcium aluminium sorosilicate mineral with formula CaAl2Si2O7(OH) 2H2O. Lawsonite crystallizes in the orthorhombic system in prismatic, often tabular crystals. Crystal twinning is common. It forms transparent to translucent colorless, white, and bluish to pinkish grey glassy to greasy crystals. Refractive indices are n?=1.665, n?=1.672 1.676, and n?=1.684 1.686. It is typically almost colorless in thin section, but some lawsonite is pleochroic from colorless to pale yellow to pale blue, depending on orientation. The mineral has a Mohs hardness of 8 and a specific gravity of 3.09. It has perfect cleavage in two directions and a brittle fracture. Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 88 Publication Date: 2010/07/09 Language: English Dimensions: 5.98 x 9.01 x 0.21 inches |

The Hardness of Metals $67.14 This book is an attempt to explain hardness measurements of metals in terms of some of their more basic physical properties. It does not deal with the atomic and crystalline mechanism of elastic or plastic deformation, but starting with the elastic and plastic characteristics it shows that the hardness behavior of metals may be expressed in terms of these characteristics. It is hoped that this presentation will provide, for physicists, engineers, and metallurgists, a better understanding of what hardness means and what hardness measurements imply. The book places an emphasis on the physical concepts involved, so that the non-mathematical reader may grasp and appreciate the general physical picture without needing to follow the more detailed treatment. |

Indentation Hardness $60.54 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles Indentation hardness tests are used to determine the hardness of a material to deformation. Several such tests exist, wherein the examined material is indented until an impression is formed; these tests can be performed on a macroscopic or microscopic scale. For measuring hardness of very small samples nanoindentation is used. When testing metals, indentation hardness correlates linearly with tensile strength. This important relation permits economically important nondestructive testing of bulk metal deliveries with lightweight, even portable equipment, such as handheld Rockwell hardness testers. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F. Binding Type: Paperback Number of Pages: 62 Publication Date: 2010/08/11 Language: English Dimensions: 6.00 x 9.02 x 0.15 inches |

The Hardness Factor $11.99 Hard is good, harder is better -- for your health, your libido, your life. Such is the provocative premise behind Dr. Steven Lamm's The Hardness Factor , a groundbreaking book that will change the way men live and love. The Hardness Factor measures male health through the quality of an erection -- perhaps the greatest male motivator for better living (more so than fear of cancer, heart attack, or stroke). The Hardness Factor asks, Can men be hard and in shape for sex their entire lives? The answer is, absolutely. Here for the first time are scientific, evidence-based regimens -- emphasizing nutrition, supplements, and exercise -- to increase erectile quality. After following The Hardness Factor , you will not only achieve optimal health and sexual fitness but also understand why the penis is the best barometer of a man's health. |

Calcium $195 Calcium is a versatile carrier of signals regulating many aspects of cellular activity such as fertilization to create a new life and programmed cell death to end it. Calcium homeostasis is strictly controlled by channels, pumps and exchangers functioning as gates for calcium entry and release. Given that calcium is such a versatile messenger the field of calcium signaling is continuously and rapidly expanding. This book reviews the most recent developments in calcium signaling by leading experts in the field. It is a state-of-the-art summary of our present knowledge in this quickly growing field and provides insight into the impressive progress made in many areas of calcium signaling, while reminding us of how much remains to be learned. |

Mohs Scale of Mineral Hardness $71.7 The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science. The method of comparing hardness by seeing which minerals can scratch others, however, is of great antiquity, having first been mentioned by Theophrastus in his treatise On Stones in ca 300 BC, followed by Pliny the Elder in his Naturalis Historia circa A.D. 77.
