In terms of its properties, 881 can also be expressed in various numeral systems (for example, in binary, it is 11011000101). Additionally, in Roman numerals, it is represented as DCCCLXXXI.

The number 90 is an integer that follows 89 and precedes 91. It is a composite number, meaning it has divisors other than 1 and itself. Specifically, the divisors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.

Mass-specific quantities refer to properties or attributes of a substance that are normalized by mass. These quantities provide a way to express values per unit mass, allowing for a clearer comparison of materials or systems regardless of their total mass. Common examples of mass-specific quantities include: 1. **Specific Heat Capacity**: The amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius (or one Kelvin).

The term "digital sum" can refer to different concepts depending on the context, but it typically involves the process of summing the digits of a number until a single-digit result is obtained. This process is often used in various mathematical contexts, such as number theory or checksum calculations.

The digital sum of a number in base \( b \) refers to the sum of its digits when the number is expressed in that base. This concept is similar to finding the digit sum in base 10, but the digits are calculated according to the specified base. For example, let's say we want to calculate the digital sum of the number 345 in base 10.

A "dozen" is a term that refers to a quantity of twelve (12) items. It is commonly used in various contexts, such as counting objects, selling goods (like eggs or baked goods), and more. The term has its origins in the Latin word "duodecim," which means twelve.

A bulbous bow is a protruding bulb-like structure located at the front (bow) of a ship's hull, just below the waterline. Its primary purpose is to improve the vessel's hydrodynamics and overall performance in the water. The design of a bulbous bow helps to reduce wave resistance and increase fuel efficiency by altering the way water flows around the ship as it moves.

In telecommunications, desensitization refers to a reduction in the sensitivity of a receiver or other electronic component to incoming signals, often due to the presence of strong adjacent signals or noise. This effect can occur in various contexts, such as in radio frequency (RF) systems, where a strong signal can overwhelm the receiver's ability to detect and process weaker signals.

Adjacent-channel interference refers to the degradation of a communication signal caused by signals from nearby channels or frequency bands. This type of interference is particularly relevant in radio frequency (RF) communications, such as in telecommunications, broadcasting, and wireless networking. In scenarios where multiple channels are used, especially those that are closely spaced in frequency, signals can spill over into adjacent channels due to various factors such as spectral overlap, transmitter non-linearity, and inadequate filtering.

River ports are specialized facilities located along rivers that serve as points for the loading and unloading of cargo and passengers from boats and ships. These ports are typically equipped with various infrastructure and services to facilitate the movement of goods and people, making them essential for trade and transportation. Key features of river ports include: 1. **Infrastructure**: River ports usually have docks, wharves, and berths where vessels can be secured while loading or unloading cargo.
