What factors have contributed to total world grain production increasing, but per-person production stagnating?
tatuchka [14]

Factors have contributed to total world grain production increasing, but per-person production stagnating Expanded irrigation, fertilization, and new crop.

Grain farmers grow grains which include corn, wheat, rye, and others, which include grain sorghums. Farmers generally focus on or three varieties of grain. Many grain farmers very own their land and work for themselves.

U.S. imports of wheat grain, mainly from Canada, are small however have grown from less than 0.1 million metric tons in the 1970s to a median of two.6 million metric heaps over the past 10 years. Imports of wheat flour and products have averaged nearly 1 million metric lots yearly over the past 10 years

In crop 12 months of 2016/2017, a total of approximately 2.2 billion metric tons of grain have been produced internationally. The maximum essential grain turned into corn, based totally on a manufacturing amount of approximately 1.05 billion metric heaps in that year.

erastovalidia [21]

The International Knowledge Centre for Engineering Sciences and Technology (shortened as “IKCEST”) is a category 2 centre under the auspices of the United Nations Educational, Scientific and Cultural Organization (shortened as “UNESCO”). IKCEST was established on June 2, 2014. The Chinese Academy of Engineering is responsible for the operation and management of the IKCEST.

Under the auspices of UNESCO, IKCEST is a comprehensive and international knowledge centre devoted to the engineering sciences, technology and applied technology. IKCEST aims at connecting engineering sciences and technology institutions globally, assembling various digital resources relating to engineering sciences and technology, building up a public data service platform and corresponding service environment, and coordinating the building of various professional knowledge systems, thus providing knowledge-based services at a global scale in the form of consultancies, scientific research and education for policy-makers and engineering science and technology professionals in the world, with particular reference to the developing countries.

The specific tasks and functions of IKCEST are as follows: to establish an international engineering and technology resources hub; to establish a public data service platform, and to develop the technology for mining and analyzing knowledge from big data; to cooperatively build professional knowledge service systems, and to build capacity in developing countries; to foster interdisciplinary engineering talents with big data processing ability; and to assist UNESCO to fulfill its aims and support its action plans<span>.</span>

Match each projection to its description.A.planar projectionLines of latitude and lines of longitude are perpendicular.B.cylindr
wariber [46]

A.planar projection--------------Map with the North or South Pole at its center. Landforms are distorted toward the equator.


Planar projections project map data onto a level surface. In spite of the fact that the purpose of contact might be any point on the world's surface, the north and south poles are the most widely recognized contact focuses for most GIS databases. Different areas are utilized principally for particular applications, such a route or locational inset maps.  

At the point when the plane contacts the earth at either the north or south poles, longitude queues join at the purpose of contact and emanate outward from the post at their actual edge like the spokes on a wheel, the separation between them expanding as the separation from the contact point increments.


B.cylindrical projection----------Lines of latitude and lines of longitude are perpendicular



A cylindrical projection can be envisioned in its least complex frame as a chamber that has been folded over a globe at the equator. The points on the round framework are exchanged to the chamber which is then unfurled into a level plane. The equator is the "ordinary perspective" or perspective for these projections. This group of projections are normally used to represents the whole world.  

One of the general characteristic is lines of latitude and longitude are parallel intersecting at 90 degrees.

A technician has been asked to configure several computers with RAID. The customer wants the best RAID possible with three drive
alisha [4.7K]

Answer:

A Level 6 RAID

Explanation:

The best RAID to use in this case is a level 6 RAID because it has a double parity block which makes it easier to achieve better data redundancy than the level 5 RAID. This enhances the fault tolerance for upto two drive breakdowns in the array. The parity blocks for each disk are two in number and are stored on different disks across the array.
