as a way of expression. However, other people say they have created to for them to notice. Others think that it is a protest against the parents.
In my opinion, the main reason of joining the group is the ability to show your solidarity with like-minded friends.
Different subcultures have their own beliefs, values, fashion and favourite music. For example, hippies of the 1970s wore unusual clothes and had long hair. Furthermore, defending his point of view, the hippies do not resort to violence. By their nature they are peaceful and try to live in harmony with nature.

unfortunately, not all groups are peaceful. Sadly, some of them are prepared to physically hurt people in an attempt to get their message across. For example, punks are opposed to the values and norms in the society. They express this in loud and violent music, strange clothing and hair of unusual colours.

or cereals and constitute important grain crops exceeded only by
wheat, rye and corn in acreage and value. What the origin of
common oats is remains in doubt but its cultivation is not so old as
wheat.
The species of oats, which include all the cultivated varieties,
appears to have arisen in the eastern temperate zone of Europe or
western Asia. As for barley, it has been known for thousands of
years and must have been cultivated before any recorded history. In
the barley ear spikelets resemble those of wheat while the spikelets
of oats differ in that they have stalks forming a panicle usually 9 to
12 inches long. there exist many different kinds of oats and barley
and as with the other small grains, there are many differences as to
characteristics between varieties raised.
Both oats and barley are most commonly seeded in the spring and
grown as annuals; yet each has varieties that are winter annuals to
be sown in the fall. No winter-oat varieties have been developed
thus far are sufficiently hardy for dependable production where
winters are severe. They are not grown as far north nor at such
elevations as barley, the hardiest winter barleys resisting winter
killing better than any of the present varieties of winter oats. Of the
spring sown oats some are very early. These are favored by the
warm climate of the south, for they complete the growth before the
hottest, driest part of the season.
Both oats and barley are grown by essentially identical seeding,
cultural, and harvest methods. They fit conveniently into same sort
of crop rotations, have about the same effect on the land on the
succeeding crops, and have approximately the same seasonal labor
requirements.

LARGE-SCALE INTEGRATION IN ELECTRONICS

The most advancing technology of the present industrial age is that of electronics. The introduction of the transistor in its day seemed a marvel of compactness compared with the glass vacuum tube. Now the size of electronic devices has been reduced by 10 every five years which has led to a great compression. When the term microelectronics first came into use, a chip of silicon a tenth of a square inch might hold 10 to 20 transistors, together with a few diodes, capacitors and resistors. Now such chips can contain thousands of separate electronic components.

Before the appearance of the transistor each type of component in an electronic circuit was made from one or more materials with the required electrical characteristics. For example, carbon was used for resistors, ceramics and a dielectric for capacitors, tungsten for emitters in vacuum tubes and so on. These components were then used like building blocks in creating a circuit with specified characteristics and responses. Circuits were combined into systems, such as a radio transmitter, a radio receiver, a radar set or a computer.

From the earliest days electronics has been a technology of complex interconnections. A small radar set can easily have as many interconnections as an oil refinery. To simplify a system design and reduce the number of interconnections engineers developed a series of standard circuit modules. Each module performed a specific function and was used as logical building block for creating the systems. The transistor could readily be assembled with resistors and capacitors of about the same size on a small plastic board. These modular circuit boards of the size of a playing card could then be plugged together as needed.

As transistor technology developed it was important to decrease the size of components and the length of interconnections. The physical limit of finding room for connections in an ever decreasing area was fast approaching. This limitation and the complexity of system design made the search for a new technology imperative.

The technology that resulted was microelectronics embodied in the integrated circuit. It made possible to produce (as a part of a single chip of silicon) transistors, diodes, resistors and capacitors joining them into a complete circuit.

The technology that produces such high-density electronic circuits is called large-scale integration, or LSI. Although the term has no precise definition, it is usually reserved for integrated circuits that comprise 100 or more “gates”, or individual circuit functions, with a density of 50,000 to 100,000 components per square inch. If the upper value could be achieved throughout a cubic inch of material, the density of electronic components would be about a fourth of the density of nerve cells in the human brain.

It now seems inevitable that microelectronic circuits, including LSI, will soon find their way into a variety of new applications which will have great impact on industry and everyday life.
