** Three thousand student activists at University of California, Berkeley surround and block a police car from taking a CORE volunteer arrested for not showing his ID, when he violated a ban on outdoor activist card tables.

** Dragon Ball Z (" Transformed at Last ," October 18, 1999 ): Goku transforms into a Super Saiyan for the first time in the United States ; aired on Toonami, a now-defunct block on Cartoon Network.

** To apply access policy to network services or content, e. g. to block undesired sites.

** The sheave is the wheel within a block, or a spar, over which a line is rove.

** A fiddle block has two or more sheaves in one block, each with its own axle, so the sheaves are aligned.

** A snatch-block can be closed around a line, to grab the line, rather than threading the end of the line through the block.

** Nickelodeon operates three digital channels separate from the main feed: Nick Jr., a channel devoted to preschool programming ; TeenNick, aimed at teenagers with mostly live-action programs ( which includes a two hour 1990s block in late night ); and Nicktoons, which primarily ( although not exclusively ) runs animated programming.

** Variable block-size motion compensation ( VBSMC ) with block sizes as large as 16 × 16 and as small as 4 × 4, enabling precise segmentation of moving regions.

** An exact-match integer 4 × 4 spatial block transform, allowing precise placement of residual signals with little of the " ringing " often found with prior codec designs.

** An exact-match integer 8 × 8 spatial block transform, allowing highly correlated regions to be compressed more efficiently than with the 4 × 4 transform.

** Adaptive encoder selection between the 4 × 4 and 8 × 8 transform block sizes for the integer transform operation.

** Heroin, a semi-synthetic opioid

** Suxamethonium ( muscle type receptors )

** Cardiopulmonary receptors sense a decreased blood volume, and signal to area postrema and nucleus tractus solitarius as well.

** The upper airway receptors are responsible for reflex responses such as, sneezing, coughing, closure of glottis, and hiccups.

** a synapse that releases glutamate more slowly than normal, thus activating only high affinity NMDA receptors, but not low affinity AMPA receptors

** a synapse that lacks postsynaptic AMPA receptors

** G protein-coupled receptors – Composed of seven transmembrane alpha helices.

** receptor tyrosine kinase – Functional receptors are homodimers.

** nuclear receptors – Composed of a C-terminal DNA-binding domain ( DBD ) and a N-terminal ligand-binding domain ( LDB ).

** Ropinirole — agonist at D2, D3, and D4 receptors

** Pramipexole — agonist at D2, D3 and D4 receptors

** Tianeptine — paradoxical antidepressant ( considered to be a selective serotonin reuptake enhancer ( SSRE ) ( note that no widely known proof of direct SSRE action exists )), improves mood and reduces anxiety ; action on the NMDA and AMPA receptor, a hypothesized mechanism of action, based on tianeptine's effect of promoting stress-associated impaired neuroplasticity ; it enhances the extracellular concentration of dopamine in the nucleus accumbens and modulates the D < sub > 2 </ sub > and D < sub > 3 </ sub > dopamine receptors, but this effect is modest and almost certainly indirect.
