Aquacultural engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. [1] Common aquaculture systems requiring optimization and engineering include sea cages, ponds , and recirculating systems. [ 2 ]
Number sense in animals is the ability of creatures to represent and discriminate quantities of relative sizes by number sense. It has been observed in various species, from fish to primates . Animals are believed to have an approximate number system , the same system for number representation demonstrated by humans, which is more precise for ...
[1] [2] [3] Time and methods engineering use statistics to study repetitive operations in manufacturing in order to set standards and find optimum (in some sense) manufacturing procedures. Reliability engineering which measures the ability of a system to perform for its intended function (and time) and has tools for improving performance. [2 ...
Although food engineering is a relatively recent and evolving field of study, it is based on long-established concepts and activities. [1] The traditional focus of food engineering was preservation, which involved stabilizing and sterilizing foods, preventing spoilage, and preserving nutrients in food for prolonged periods of time.

The Beverton–Holt model, introduced in the context of fisheries in 1957, is a classic discrete-time population model which gives the expected number n t+1 (or density) of individuals in generation t + 1 as a function of the number of individuals in the previous generation, + = + /.
There is a general consensus among historians that the roots of the industrial engineering profession date back to the Industrial Revolution.The technologies that helped mechanize traditional manual operations in the textile industry including the flying shuttle, the spinning jenny, and perhaps most importantly the steam engine generated economies of scale that made mass production in ...
That is, for every prime number p greater than 3, one has the modular arithmetic relations that either p ≡ 1 or 5 (mod 6) (that is, 6 divides either p − 1 or p − 5); the final digit is a 1 or a 5. This is proved by contradiction. For any integer n: If n ≡ 0 (mod 6), 6 | n; If n ≡ 2 (mod 6), 2 | n
Similarly, if the final digit on the right of the decimal mark is zero—that is, if b n = 0 —it may be removed; conversely, trailing zeros may be added after the decimal mark without changing the represented number; [note 1] for example, 15 = 15.0 = 15.00 and 5.2 = 5.20 = 5.200.
