The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, ...
Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).
An activity involving a ship under Sea Toll Program. All ships under the program have "Tol Laut" (meaning Sea Toll) written on their hull. The Sea Toll Program (Indonesian: Tol Laut), sometimes called the Sea Highway Program, [1] is a program initiated by former Indonesian president Joko Widodo.
Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability. Today, bulk carriers make up 21 percent of the world's merchant fleets, [ 2 ] and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT).
In 1947 the Transportation Corps developed the Transporter, a rigid, corrugated steel container with a 9,000 lb (4,100 kg) carrying capacity, for shipping household goods of officers in the field. It was 8 ft 6 in (2.59 m) long, 6 ft 3 in (1.91 m), and 6 ft 10 in (2.08 m) high, with double doors on one end, mounted on skids, and had lifting ...
Net register tonnage (NRT, nrt, n.r.t.) is a ship's cargo volume capacity expressed in "register tons", one of which equals to a volume of 100 cubic feet (2.83 m 3).It is calculated by subtracting non-revenue-earning spaces i.e. spaces not available for carrying cargo, for example engine rooms, fuel tanks and crew quarters, from the ship's gross register tonnage.
where r is the growth rate of the population (N), and K is the carrying capacity of its local environmental setting. Typically, r-selected species exploit empty niches , and produce many offspring , each of whom has a relatively low probability of surviving to adulthood.
The standard logistic function is the logistic function with parameters =, =, =, which yields = + = + = / / + /.In practice, due to the nature of the exponential function, it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.
