FRIENDSHIP & GOALS

WHAT IS FRIENDSHIP:

 For all the attention we pay to love stories, some of the most compelling stories (in fiction or not) are about best friends, like Thelma and Louise, Woody and Boaz, and even Captain Kirk and Spock. "However, the two sieges had gone through each other's back thick and thin, although there were many stumbling blocks in the way." But, just like romance, if you've ever tried to make a new friend and only things haven't been clicked, it's probably because one of the essential components of friendship simply wasn't there.

All of this is good and good, but if a potential new friend doesn't see the same happy charm in you, it's unlikely anything deep and lasting will come from him. Yet, we do not know when and where friendship will develop. Usually, it arises from a common interest or a hobby, and brings people together because they are at the same stage of life, like new or retired parents. People of similar backgrounds and cultures tend to come together through interconnections around shared experiences for life. Although most of these relationships take time to really go deep, friendship sometimes resembles a lightning strike. "Sometimes you can be in a large group of new people and catch someone's eye and that's like 'boom!' - instant friendship," Diggs-White says of an experience she calls "the click phenomenon." "It's like that rush of "love at first sight," but it's friendship, not romantic."

Dr. Susan Diggs-White, a psychologist and friendship expert at the University of Northern Illinois, explains in an email interview that "friendships are relationships that involve two very critical dimensions - interconnectedness and voluntary participation." As anyone who's ever been friends know, it's a complex process and an experience. She says that true friendships are characterized by each member's willingness to deal with the other, as it is a shared interest in each other's experiences and ideas, as well as a sense of belonging and interdependence. Friendships require reciprocity - admiration, respect, trust, and emotional and emotional support.

In other words, friendship is great, and a lot of ink is stolen in citation the virtues of having friends. That doesn't mean friendship is easy. It takes time and effort, and it requires that people put someone other than themselves first at times. But in return for this work, a friend can provide a tremendous amount of support and comfort in good times and in distress. Keep reading to learn more about various types of friendship.

Truly, good friendships are very important to our general happiness. A 2017 study in the journal Personal Relations found that having strong friendships is actually more evidence of overall health and happiness in old age than just sharing and supporting the family! But the benefits of friendship in general are lifelong. Research has shown that people with good friends often feel happier, less stressed, and more like those without friends. A strong network of friends also increases self-confidence, as well as providing much-needed emotional support during difficult times, such as illness, missing a loved one or getting divorced.

What are the different types of Friendship:

Once again, a person rarely moves from a virtual stranger to Anstee. “Friendships develop as each person reveals himself a bit more, and the “friend who makes him” matches the revelation he reveals himself. It's how to build trust between people — through increasingly intimate or personal information exchange. In fact, research has revealed that it takes about 50 hours to become just a passing friend, then 90 hours to be elevated to a regular friend. Then it takes about 200 more hours of interaction to develop a “close friendship”! [Source: Hellman].

Before we reach the integrity of individual types of friends, it is important to note that as individuals, we prefer different types of social structures, according to research published in Contexts 2016. These narrow flavors tend to maintain a dense social network where everyone is friends with each other, while the fragmented have multiple groups of friends, which often come from different periods of time in their lives or perform different functions such as counseling or entertainment. The owners have personal relationships but avoid groups [source: Wang].

According to Diggs-White, there are four basic types of friendship: friend, best friend and best friend. "The level of friendship deepens as the level of exchange, mutual respect and friendship grows," she explains. Knowledge is easy enough to classify. It's people who are not totally strangers, who you normally meet in a place like a coffee shop or a work cafeteria, but you don't really know. “They're people we know well enough to have small conversations with on a regular basis,” she says, “but they're not really people we can invite to a dinner party or visit if we need help.”

By contrast, the “friends” in the record number are those we are trying to meet or mix with. "Women who participate in motor racing duties in children's sports and who usually hang around with them or spend time with them at games, for example. or people who are your “group” and with whom you tend to communicate on a regular basis.

These friends are certainly valuable, but when things get more complicated, you're more likely to seek a "close friend" for help or support. They're also the people who trade secrets. There isn't only a strong level of trust between these friends, there's also a lot of unconditional respect and intimacy, Diggs White explains in detail. You may not like your best friends' choices, but you defend your right to make them.

Last but not least, there is a real lack of “best friend” phenomena. "The best friend is the rarest kind of friend and kind of friend we all need to have in our lives. It's a friend that happens to you without having to explain yourself. He's the kind of friend who loves you no matter what. They're not necessarily people you talk to every day. "Weeks or months may pass without calling, but when you reconnect, it's as if no time has passed. These friendships differ in their ability to practice and abide even if life temporarily blocks the way. These are “friends of heart to heart” or “friends of spirit” and can give you comfort even if you are away from contacting this friend.”

It's important to note that in today's social media-based society, people often feel confused about their status as friends. “The process of 'making real friends' really hasn't changed! What has changed is the generic label of acquaintances, acquaintances, and close friends that all have the same title, “Friend,” says Diggs-White. "Not all followers, Facebook friends and others will be "real friends," because there's probably not a lot in common with them, you rarely see them in person (if there's anything at all), and they probably couldn't get them to get a lot of support."

Sometimes even seemingly real friendships get worse. Keep reading to learn more about the toxic signs of friendship, and how to take action.

SOURCE OF ENERGY

Source of energy:


Since electric power is produced by energy available in different forms in nature, it is desirable
Search various energy sources. These energy sources are:

(1) Sun       (ii) Wind      (iii) Water      (iv) Fuel        (v) Nuclear energy.

Of these sources, solar and wind energy have not been widely used because of
At present, the other three sources of water, fuel and nuclear power are
It is used mainly for electric power generation.

(1) Sun:

                 The Sun is the primary source of energy. The energy can be radiated by the sun They focus on a small area with reflectors. This heat can be used to raise steam Electric power can be produced with the aid of a set of turbine switches.
 But this method has limited application due to:
      (a) Requires a large area to generate even a small amount of electricity
      (b) Cannot be used on cloudy days or at night
      (j) It is uneconomical.
                Nevertheless, there are some locations in the world where very strong solar radiation is received These sites are receiving more attention Building solar plants.

(2) Wind:

               This method can be used where air flows for a considerable period of time. And the wind power is used to power the windmill that runs a small generator Electric power from a windmill that runs continuously, the generator is arranged to charge the batteries. And these batteries provide energy when the wind stops. This method has the advantages that the costs of maintenance and power generation are negligible, 
   But the flaws of this method are:
      (a) variable output, 
      (b) unreliable due to uncertainties in wind pressure and 
      (c) generation Very small.

(3) Water: 

               When water is stored in an appropriate place, it has potential energy because of The head was created. This water energy can be converted to mechanical energy with the help of water Turbines. It turns a water turbine, which turns mechanical energy into electricity This method of generating electricity has become very popular because of its depreciation production and maintenance costs.

(4) Fuel: 

               The main energy sources are solid fuels such as coal and liquid fuels such as oil and gas
fuel as a natural gas. The thermal energy of these types of fuels is converted to appropriate mechanical energy The main engines, such as steam engines, steam turbines, internal combustion engines, etc. A prime number A mobile switch operates a switch that converts mechanical energy into electrical energy. Despite the fuel It continues to enjoy its primary source of electricity, but so does its reserves
is decreasing by the day. So, the current trend is the exploitation of hydropower which is increasing or increasing Never mind that it is a constant source of strength.

(5) Nuclear energy: 

              Towards the end of the Second World War, it was discovered that a large quantity Thermal energy is liberated by fission of uranium and other fissile material. Estimated heat produced at 1 kg of nuclear fuel is equivalent to 4,500 tons of coal produced It can be used because of nuclear fission to raise energy through appropriate arrangements. Steam You can run a steam turbine that can, in turn, pay the switch to produce electricity, there are some difficulties in the use of nuclear energy. The fundamentals are
        (a) the high cost of nuclear materials
        (b) The problem of radioactive waste disposal and the lack of personnel trained to deal with the plant.

IMPORTANCE & GENERATION OF ELECTRICAL ENERGY

TRANSMISSION LINE PARAMETERS

General:

                        Energy is the basic necessity of the country's economic development. Too many essential jobs for today Turn off living objects when energy is saved stops. virtually impossible to estimate the actual amount of the part that the energy owns I played in building the present civilization modern energy has resulted in shorter working days, higher agricultural production, more efficient, healthier, more balanced agricultural production better diet and transportation facilities. CA In fact, is there an intimate relationship between the energy used per person and its dwelling? The more likely a person is to have access to energy in a country, the more likely it is to have access to energy the standard of living of its people. Energy exists in different forms in nature, but the most important form is electric power. Modern society depends a lot on the use of electric power that became part of our lives. In this chapter, we will Focusing our attention on general aspects of natural energy

Importance of electrical energy:


                       Energy may be required in the form of heat, light, momentum, etc. Current progress in science and technology made it possible to convert electric power into any desired form It gives electric power a place of pride in the modern world — the survival of industrial plants and our social structure is basically low cost and continuous electricity supply in fact, a country's progress is measured in terms of per capita energy consumption Electric power.
                Electric power exceeds all other forms of energy for the following reasons:

(1) Convenient point:

                   Electric power is a very convenient form of energy. can easily be converted to other forms of energy. For example, if we want to turn electric energy into heat, the only thing we have to do is pass an electric current through a very resistant wire like a heater. Similarly, electric power can be converted to light (such as a light bulb), mechanical energy (such as electric power), electric motors), etc.

(2) Ease of control:

                     Electrically operated machines have easy, convenient startup and control
and operation. For example, an electric motor can be turned on or off by turning on or off a switch. Similarly, with simple arrangements, the speed of electric motors can easily be changed as desired range.

(3) Increased flexibility:

                    One of the main reasons for the preference for electric power is flexibility
that they offer. It can be easily moved from one place to another with the help of the conductors.

(4) Licenses: 

                     Electric power is much cheaper than other forms of energy, and so it's comprehensive
The economic use of this form of energy for domestic, commercial and industrial purposes.

(5) Cleanliness:

                     Electric power is not associated with smoke, fumes or toxic gases. Its use thus ensures cleanliness and hygiene conditions.

(6) High transmission efficiency:

                     Electricity consumers are generally present far from their production centers. Electric power can be transported appropriately and efficiently from generation centers for consumers with the help of superconductors Identify your transmission lines.




Generation of electrical energy:




                       The conversion of available energy of different forms of nature into electrical energy electric power generation.
                        Electric power is a manufactured commodity, such as clothing, furniture, and tools The manufacture of a commodity involves the conversion of naturally available raw materials to desired shape. A similar form of electric energy results from the forms of energy available in nature.
                        But electric power differs in one important respect, and other goods may be Electricity must be produced and transferred to point of use at the moment you need it. The whole process takes a fraction of a second Real-time electricity generation takes technical and economic considerations
unique in the electric power industry. Power is available in many different form's Natural sources such as water head pressure and chemicals fuel energy, nuclear energy for radioactive materials
etc. All these forms of energy can be converted to Electric power using appropriate arrangements
The ranking is used mainly (see figure 1.1) switch is associated with the main engine. The main engine
Powered by power transferred from multiple sources burning of fuel, water pressure, wind power, etc. For example, chemical energy of fuel (e.g., coal) can be used to produce steam at high temperatures and pressure. Steam is fed the main engine can be steam engine or steam turbine. The turbine converts thermal energy to steam into mechanical energy, converted to electric power again. Similarly, other forms of energy can be converted to electric power using appropriate machinery and equipment.
