DNS Zone Transfer
DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers. A zone transfer uses the Transmission Control Protocol (TCP) for transport, and takes the form of a client–server transaction. The client requesting a zone transfer may be a secondary server requesting data from a primary server, historically referred to as master and slave. The portion of the database that is replicated is a zone.

Major (Academic)
An academic major is the academic discipline to which an undergraduate student formally commits. A student who successfully completes all courses required for the major qualifies for an undergraduate degree. The word "major" is also sometimes used administratively to refer to the academic discipline pursued by a graduate student or postgraduate student in a master's or doctoral program. An academic major typically requires completion of a combination of prescribed and elective courses in the chosen discipline. In addition, most colleges and universities require that all students take a general core curriculum in the liberal arts. The latitude a student has in choosing courses varies from program to program. An academic major is administered by select faculty in an academic department. A major administered by more than one academic department is called an interdisciplinary major. In some settings, students may be permitted to design their own major, subject to faculty approval. In the US, students are usually not required to choose their major discipline when first enrolling as an undergraduate. Normally students are required to commit by the end of their second academic year at latest, and some schools even disallow students from declaring a major until this time. A student who declares two academic majors is said to have a double major. A coordinate major is an ancillary major designed to complement the primary one. A coordinate major requires fewer course credits to complete.

Three-finger Toxin
Three-finger toxins (abbreviated 3FTx) are a protein superfamily of small toxin proteins found in the venom of snakes. Three-finger toxins are in turn members of a larger superfamily of three-finger protein domains which includes non-toxic proteins that share a similar protein fold. The group is named for its common structure consisting of three beta strand loops connected to a central core containing four conserved disulfide bonds. The 3FP protein domain has no enzymatic activity and is typically between 60-74 amino acid residues long. Despite their conserved structure, three-finger toxin proteins have a wide range of pharmacological effects. Most members of the family are neurotoxins that act on cholinergic intercellular signaling; the alpha-neurotoxin family interacts with muscle nicotinic acetylcholine receptors (nAChRs), the kappa-bungarotoxin family with neuronal nAChRs, and muscarinic toxins with muscarinic acetylcholine receptors (mAChRs).

Excelsior (Smack)
Excelsior is an authentically restored fishing smack of the Lowestoft fishing fleet and a member of the National Historic Fleet. She was built by John Chambers of Lowestoft in 1921 and worked until 1936 before being converted into a motor coaster. In 2021 Excelsior will celebrate her 100th birthday. During her time as a motor coaster she was known as Svinør and worked mainly in Norwegian waters before returning to Lowestoft in 1972. She measures 23 metres (75 ft) long with a beam of 5.9 metres (19 ft) and is ketch rigged and is the last traditional sailing trawler able to tow a full-sized traditional trawl net. Excelsior was restored in 1989 and operates as a sail training vessel based out of Lowestoft, able to accommodate up to 17 people, including 12 trainees or passengers.

URL Normalization
URL normalization is the process by which URLs are modified and standardized in a consistent manner. The goal of the normalization process is to transform a URL into a normalized URL so it is possible to determine if two syntactically different URLs may be equivalent. Search engines employ URL normalization in order to assign importance to web pages[clarify] and to reduce indexing of duplicate pages. Web crawlers perform URL normalization in order to avoid crawling the same resource more than once. Web browsers may perform normalization to determine if a link has been visited or to determine if a page has been cached.

Countries Dependent on the Bay of Bengal
The countries dependent on the Bay of Bengal include littoral and landlocked countries that depend on the Bay of Bengal for maritime usage. Historically, the Bay of Bengal has been a highway of transport, trade and cultural exchange between diverse peoples encompassing South Asia and Southeast Asia. Today, the Bay of Bengal region is the convergence of two major geopolitical blocs- the Association of Southeast Asian Nations (ASEAN) and the South Asian Association for Regional Cooperation (SAARC). The Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation (BIMSTEC) promotes regional engagement in the area. The Bay of Bengal countries are often categorized into a maritime subregion. The bay hosts vital shipping routes linking its littoral and landlocked hinterland with the Indian Ocean. Its sea bed is being explored and exploited for hydrocarbon reserves.
