The world is being shattered by the exploding demand for drugs. Methamphetamine was the major stimulant drug used until the 1980's. Then cocaine became the drug of choice. Both of these stimulants were ingested by swallowing, snorting & injection. Smoking these drugs, although possible, was not preferred until the mid 80's. In 1983 crack cocaine was introduced, quickly reached epidemic status & has not yet peaked. Smokable methamphetamine called crystal meth or ice has reached an epidemic stage in Hawaii & threatens mainland states. These smokable drugs are immensely addictive & dangerous. Crack is available everywhere as is methamphetamine. CRACK, COCAINE, METHAMPHETAMINE & ICE is written by a psychologist who has many years of experience with drug-driven offenders& with drug-abusing clients. The book presents disturbing realities to all readers via dramatic stories & informs both lay & professional readers. It employs careful research into supply, prevention, treatment & law enforcement relating to the war on drugs. In order to gain current knowledge about the possible "ice storm," the author has done careful field research in Hawaii & in California. This is a book every citizen should read! For every parent & treatment-related professional, it comprises a gold mine of information.

The phenomena relating to the fracture behaviour of ice under impact loading are common in civil engineering, for offshore structures, and de-ice processes. To reduce the damage caused by ice impact and to optimize the design of structures or machines, the investigation on the dynamic fracture behaviour of ice under impact loading is needed. This work focuses on the dynamic crack propagation in ice under impact loading. A series of impact experiments is conducted with the Split Hopkinson Pressure Bar. The temperature is controlled by a cooling chamber. The dynamic process of the ice fracture is recorded with a high speed camera and then analysed by image methods. The extended finite element method is complementary to evaluate dynamic fracture toughness at the onset and during the propagation. The dynamic behaviour of ice under impact loading is firstly investigated with cylindrical specimen in order to obtain the dynamic stress-strain relation which will be used in later simulation. We observed multiple cracks in the experiments on the cylindrical specimens but their study is too complicated. To better understand the crack propagation in ice, a rectangular specimen with a pre-crack is employed. By controlling the impact velocity, the specimen fractures with a main crack starting from the pre-crack. The crack propagation history and velocity are evaluated by image analysis based on grey-scale and digital image correlation. The main crack propagation velocity is identified in the range of 450 to 610 m/s which confirms the previous results. It slightly varies during the propagation, first increases and keeps constant and then decreases. The experimentally obtained parameters, such as impact velocity and crack propagation velocity, are used for simulations with the extended finite element method. The dynamic crack initiation toughness and dynamic crack growth toughness are determined when the simulation fits the experiments. The results indicate that the dynamic crack growth toughness is linearly associated with crack propagation velocity and seems temperature independent in the range -15 to -1 degrees.
