More than 30 years ago the hypothesis of an interventional approach in patients with unstable angina or non–ST-segment elevation myocardial infarction (NSTEMI) was considered only after a "cooling-off" period. This negative attitude was in part justified by the lack of effective antithrombotic adjunctive therapies and devices in the management of lesion containing thrombus and the subsequent early hazard of percutaneous coronary intervention (PCI). The delay—many days or weeks after hospital admission—to

Chromium (Cr)‚ iron (Fe) and aluminium (Al) dissolve in dilute nitric acid‚ which the concentrated acid forms a metal oxide layer that protects the metal from further oxidation‚ and it is called passivation.

Why an ice cube at 0°C is more effective in cooling soft drink than the same mass of water at 0 °C? Enthalpy of fusion is the change in enthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point would

Corrosion Let metal sit surrounded by oxygen for a while and the metal will corrode. Corrosion is the chemical reaction that takes place when a metal is in contact with oxygen. The metal reacts with the oxygen to form a compound called an oxide on the surface of the metal. The metal becomes tarnished and loses its shine. Metals high in the reactivity series (an observable series of metals‚ in order of reactivity from highest to lowest) corrode more quickly than less reactive metals

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because
