Site-specific recombination is a precise genetic engineering process that allows for the targeted insertion, deletion, or inversion of DNA sequences at specific locations within a genome. This mechanism is facilitated by recombinase enzymes that recognize and bind to specific DNA sequences, enabling the manipulation of genetic material with high specificity and efficiency.
Ductility is a material property that indicates a substance's ability to undergo significant plastic deformation before rupture, typically characterized by the material's capacity to be stretched into a wire. It is crucial in determining how materials can be shaped and used in various applications, especially in construction and manufacturing industries.
Porosity is a measure of the void spaces in a material and is a critical factor in determining the storage and movement of fluids in geological formations. It significantly influences the physical properties and behavior of materials, impacting fields like hydrogeology, petroleum engineering, and soil science.
Cohesion refers to the degree to which the elements of a module or system work together as a whole, enhancing its functionality and maintainability. High cohesion typically results in more robust, understandable, and reusable code or systems, as each component is focused on a single task or closely related tasks.
Rock Mass Rating (RMR) is a geomechanical classification system used to assess the quality and stability of rock masses, aiding in the design and construction of engineering projects such as tunnels, foundations, and slopes. It evaluates parameters like rock strength, joint spacing, joint condition, groundwater conditions, and orientation of joints to provide a numerical rating that reflects the rock mass's suitability for engineering purposes.
