Dismasting-Dismasting-Dismasting, also spelled demasting, occurs to a sailing ship when one or more of the masts responsible for hoisting the sails that propel the vessel breaks.

Dismasting-Dismasting-Dismastings are rarely life-threatening after the initial event and the broken mast is cut away. However, dismastings appear to have contributed to the loss of life at sea as a consequence of crews abandoning an otherwise perfectly seaworthy vessel in favor of a life raft. This has led to a sailin... | milkshake721/2.1M-wiki-STEM |
Dismasting-Dismasting-After a dismasting, the crew might jury rig, or fashion, a makeshift mast(s) and sails from salvaged and spare materials carried aboard.

Dismasting-Factors contributing to dismastings-Dismastings occur for many reasons.

Quine–McCluskey algorithm-Example-Step 1: finding prime implicants First, we write the function as a table (where 'x' stands for don't care): One can easily form the canonical sum of products expression from this table, simply by summing the minterms (leaving out don't-care terms) where the function evaluates to one: f... | milkshake721/2.1M-wiki-STEM |
Quine–McCluskey algorithm-Example-When going from Size 2 to Size 4, treat - as a third bit value. Match up the -'s first. The terms represent products and to combine two product terms they must have the same variables. One of the variables should be complemented in one term and uncomplemented in the other.

Quine–McCluskey algorithm-Example-Note: In this example, none of the terms in the size 4 implicants table can be combined any further. In general this process should be continued (sizes 8, 16 etc.) until no more terms can be combined. | milkshake721/2.1M-wiki-STEM |
Quine–McCluskey algorithm-Example-Step 2: prime implicant chart None of the terms can be combined any further than this, so at this point we construct an essential prime implicant table. Along the side goes the prime implicants that have just been generated (these are the ones that have been marked with a "*" in the pr... | milkshake721/2.1M-wiki-STEM |
Quine–McCluskey algorithm-Example-To find the essential prime implicants, we look for columns with only one "✓". If a column has only one "✓", this means that the minterm can only be covered by one prime implicant. This prime implicant is essential.
For example: in the first column, with minterm 4, there is only one "✓... | milkshake721/2.1M-wiki-STEM |
Quine–McCluskey algorithm-Example-The second prime implicant can be 'covered' by the third and fourth, and the third prime implicant can be 'covered' by the second and first, and neither is thus essential.

Jumping translocation breakpoint-Jumping translocation breakpoint-The jumping translocation breakpoint protein (JTB), also known as prostate androgen-regulated protein (PAR), is a protein that in humans is encoded by the JTB gene. It is an orphan receptor with unknown function.The JTB family of proteins contains severa... | milkshake721/2.1M-wiki-STEM |
NAD+ Five-prime cap-NAD+ Five-prime cap-In molecular biology, the NAD+ five-prime cap (NAD+ 5’ cap) refers to a molecule of nicotinamide adenine dinucleotide (NAD+), a nucleoside-containing metabolite, covalently bonded the 5’ end of cellular mRNA. While the more common methylated guanosine (m7G) cap is added to RNA by... | milkshake721/2.1M-wiki-STEM |
NAD+ Five-prime cap-NAD+ Five-prime cap-In eukaryotic cells, while the more commonly observed m7G cap promotes the stability of the mRNA and supports translation, the NAD+ cap targets the RNA transcript for decay, facilitated by the non-canonical decapping enzyme, DXO. Considering the centrality of NAD in redox chemist... | milkshake721/2.1M-wiki-STEM |
NAD+ Five-prime cap-Function in prokaryotes-In prokaryotes, the 5’ NAD+ modification is established by bacterial RNAP during transcription initiation and has been shown to display functions analogous to those of the eukaryotic 5’ cap. In-vitro transcribed NAD-modified RNA was shown to be more resistant to RNase E, the ... | milkshake721/2.1M-wiki-STEM |
NAD+ Five-prime cap-Function in prokaryotes-NAD capping has also been suggested to recruit specific proteins to the 5’ end of the RNA as NAD is one of the most common protein ligands. NAD-binding pockets are well characterized in many proteins and could help the localization of the RNA to an enzyme or receptor. Many NA... | milkshake721/2.1M-wiki-STEM |
NAD+ Five-prime cap-Function in eukaryotes-NAD+ 5’ capped RNA have been found in yeast, humans, and Arabidopsis thaliana. In eukaryotes, the NAD+ cap is removed by non-canonical decapping enzymes from the DXO family. DeNADing by DXO results in a 5’ end monophosphate RNA distinct from NudC which results in NMN plus 5′ m... | milkshake721/2.1M-wiki-STEM |
