Permanent weight loss

The advertised product will cause permanent weight loss, even when the user stops using the product. [Pg.56]

Her first book, The No-Time-to-Lose Diet, was released in January 2007, and the paperback version, The Busy Person s Guide to Permanent Weight Loss, was released in May 2008. Her latest book. The Calendar Diet, was released in March 2012. [Pg.8]

Subsequent to re-drying, weight loss in pure resin is almost zero only at 95 °C and after 1000 h, a small, permanent weight loss occurs. Figure 5.359 hottom. For short exposure times, glass fiber-reinforced resin also shows only minimal, permanent weight loss, which, however, subsequently increases with time [874]. [Pg.819]

It is desirable that the plasticizer compounded with a polymer be permanently retained. Loss of plasticizer changes the properties of a given formulation, and can be produced by volatilization, extraction or migration. The volatility of a plasticizer in a formulation can be related to the surface area, thickness of the polymeric material, and viscosity (e.g. molecular weight) of the plasticizer itself. [Pg.628]

Signs and Symptoms Initial symptoms include fever, generalized weakness, back pain, dizziness, and extreme weight loss. There may also be occasional nausea and vomiting. Fever may be biphasic. In some cases the illness can become hemorrhagic or cause inflammation of the brain leading to headaches, coma, or seizures. Can also cause inflammation of the eyes with an intolerance to light. Up to 10% of affected patients may have some permanent vision loss. [Pg.572]

Lead is an acute and a chronic toxicant. Acute effects are ataxia, headache, vomiting, stupor, hallucination, tremors and convulsions. Chronic symptoms from occupational exposure include weight loss, anemia, kidney damage and memory loss. (Patnaik, P. 1999. A Comprehensive Guide to the Hazardous Properties of Chemical Substarwes, 2nbrain damage has been noted among children. Lead bioaccumulates in bones and teeth. The metal is classified as an environmental priority pollutant by the US EPA. [Pg.458]

The immediate effects of increased temperature are an increase in the plasticity of the lignin and an increase in spatial size, which reduces intermolecular contact and is, thus, recoverable. Permanent effects manifest themselves as an actual reduction in wood substance or weight loss via degradative mechanisms, and are thereby nonrecoverable. [Pg.218]

As with permanent viscosity loss, temporary viscosity loss is a function of molecular weight, thus the higher the molecular weight, the greater the temporary viscosity loss. It is also important to note that engine oils based on VI improvers which exhibit no permanent viscosity loss in service are still generally non-Newtonian, i.e. the molecules are distorted but there is insufficient energy to break chemical bonds. [Pg.173]

Primary polymer structure may account for some of the viscosity loss behaviour, but VI improvers which function as associative thickeners are a major confounding factor. When the physically associated multi-polymer structures enter a shear field, they can dissociate into their separate molecular species. These smaller individual polymers are low enough in molecular weight that they degrade either slowly or not at all. When the molecules leave the shear field, they associate again so that there is little or no permanent loss of viscosity. However, when in the shear field, the contribution to viscosity is from the smaller, distorted individual molecules. The net result is a system which exhibits a high temporary viscosity loss relative to its low permanent viscosity loss. [Pg.174]
