Context_4 : An analytical balance (often called a "lab balance") is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product. Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure from causing an error in reading. Single pan mechanical substitution balance maintains consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added.

Context_10 : Gymnocalycium mihanovichii, often called chin cactus, is a species of cactus from South America commonly grown as a houseplant. The most popular cultivars are varied mutants which completely lack chlorophyll, exposing the red, orange or yellow pigmentation. These cultivars are often called "moon cactus". Since chlorophyll is necessary for photosynthesis, these mutations die as seedlings unless grafted onto another cactus with normal chlorophyll. fact_1 : Blankety Blanks is an Australian game show based on the American game show "Match Game". fact_2 : Graham Cyril Kennedy AO (15 February 1934 – 25 May 2005) was an Australian entertainer and variety performer, as well as a personality and star of radio, theatre, television and film. fact_3 :  He was often called "Gra Gra" (pronounced "gray-gray").
