Farmers who grow GM foods increase production with less labor and less land. Businesses sell farmers genetically modified seeds that resist certain pesticides and herbicides produced by the company. (Herbicides kill weeds and other plants that threaten the crop.) With these seeds, farmers can use toxic chemicals without harming the crop. Aquaculture—primarily the cultivation of fish and shellfish—was practiced in China, India, and Egypt thousands of years ago.

In a time-of-flight camera, the distance resolution is usually equal to the standard deviation of the signal expressed in unit of length. If the sensor has a digital output, the output is essentially an approximation of the measured property. A hysteresis error causes the output value to vary depending on the previous input values. If a sensor's output is different depending on whether a specific input value was reached by increasing vs. decreasing the input, then the sensor has a hysteresis error. An oxygen sensor in a car's emission control system detects the gasoline/oxygen ratio, usually through a chemical reaction that generates a voltage. A computer in the engine reads the voltage and, if the mixture is not optimal, readjusts the balance.

They enable individuals, institutions, corporations, regions, and nations to interact and assume economic, social, cultural, or political activities. Understanding how mobility is linked with the geography of transportation is the primary purpose of this textbook. We are the only association that covers all sustainable transport modes, in all regions, worldwide. With members from all parts of the world in this sector, we are a global centre of knowledge and know-how on all things related to public transport. For the major types of propulsion used in modern forms of transportation, see energy conversion.

The final classification of the sensors are Analog and Digital Sensors. Analog Sensors produce an analog output i.e., a continuous output signal (usually voltage but sometimes other quantities like Resistance etc.) with respect to the quantity being measured. There are numerous definitions as to what a sensor is but I would like to define a Sensor as an input device which provides an output with respect to a specific physical quantity . This type of paper provides an outlook on future directions of research or possible applications.

Researchers at SalmoBreed of Bergen, in Norway, have employed it not to create bigger, faster-growing fish but to attack two of fish farming’s banes—infestation and infection. By tracking SNPs (single-nucleotide polymorphisms, a variation of a single genetic letter in a genome used as a marker) they have produced varieties of salmon resistant to sea lice and also to pancreas disease, a viral illness. Dr Ort suggests tweaking chlorophyll molecules in order to capture a wider range of frequencies and deploy the resulting energy more efficiently. He is also looking at improving the way plants absorb carbon dioxide. AQUAmax and Artesian are drought-tolerant strains of maize developed, respectively, by DuPont and Syngenta.
