How do people see disability today?

Some time ago, people’s idea of disability was very distressing, especially towards people with disability and their families. If a child was born with any kind of disability, they _____________ that to many strange taboos, spiritual and traditional beliefs.

Today, disability is seen very differently. Education, information, support services, policy and accessibility efforts by many modern societies have empowered people with disabilities, together with _____ families, to rise to their fullest potential. Children with disability are able to go to school and feel part of society. Many people with disability have grown to become great, successful people.

Ray Charles and Steve Wonder, both blind from childhood, are some of ____________ musicians in the world. Marlee Matlin, ______ lost her hearing from childhood, is a great Standup Comedian and Actress. Chris Burke, a favorite American TV character, and writer, is a person with Down Syndrome. Nick Vujicic is _______ Australian Christian Evangelist and Motivational Speaker. Born ______ 1982 with a rare disorder, characterized by no hands and legs, has lived to inspire millions and continue to empower people.

Disability is part of life. People with disability have potential too, just like people without a disability. They have the same rights as everyone else and if people with disabilities, families, and society can work together on policy, we can make society all-inclusive and every person will have a fair chance to be the best they can be.

Introduction to Climate change

Many people make Climate Change and Global Warming a scary and difficult thing to understand, _______ it’s not.

Scientists have warned that the world's climate has changed a lot, and has affected many living and non-living things. Many places _______ were warmer are now getting colder, and many colder regions are getting much colder or even warmer nown as Global Warming).

For example, _________ 1901 and 2012, it is believed that the earth's temperature has risen by 0.89 °C. Rainfall amounts have also risen in the mid-latitudes of the northern hemisphere since the beginning of the 20th Century. It is also believed that sea levels have risen up to about 19cm globally, with lots of glaciers melting in addition.

Some people do not believe that these are caused by human activities. They think it is all political actions and falsehood intended to cause panic among humans.

Well, whatever it is, we would like to know more, and take a few good points from this confusion, and use them to make our world a better place to live.

A Brief and Simplified Description of Papermaking

The paper we use today is created from individual wood fibers that are first suspended in water and then pressed and dried into sheets. The process of converting the wood to a suspension of wood fibers in water is known as pulp making, while the manufacture of the dried and pressed sheets of paper is formally termed papermaking. The process of making paper has undergone a steady evolution, and larger and more sophisticated equipment and better technology continue to improve it.

The Wood yard and Wood rooms

The process at Androscogging began with receiving wood in the form of chips or of logs 4 or 8 feet in length. From 6 AM to 10 PM a steady stream of trucks and railroad cars were weighted and unloaded. About 40 percent were suplied by independents who were paid by weight their logs. The mill also received wood chips from lumber mills in the area. The chips and logs were stored in mammoth piles with separate piles for wood of different species (such as pine, spruce, hemlock).

When needed, logs were floated in flumes......(1).....the wood yard.....(2).....one of the mill’s three wood rooms. There, bark was rubbed......(3)........in long, ribbed debarking drums by tumbling the logs against one another. The logs then fell into a chipper;......(4)......seconds a large log was reduced to a pile of chips approximately 1 inch by 1 inch by 1/4 inch.

The chips were stored in silos. There were separate silos for softwoods (spruce, fir, hemlock, and pine) and hardwoods (maple, oak, beech, and birch). This separate and temporary storage of chips permitted the controlled mixing of chips into the precise recipe for the grade of paper being produced.

The wood chips were then sorted through large, flat vibrating screens. Oversized chips were rechipped, and ones that were too small were collected for burning in the power house. (The mill provided approximately 20 percent of all its own steam and electricity needs from burning waste. An additional 50 percent of total electricity needs was produced by harnessing the river for hydroelectric power.)

Once drawn from the silo into the digesters, there was no stopping the flow of chips into paper. 

Pulpmaking

The pulp made at Androscoggin was of two types: Kraft pulp (produced chemically) and ground wood pulp (produced mechanically). Kraft pulp was far more important to the high quality white papers produced at Androscoggin, accounting for 80 percent of all the pulp used. Kraft pulp makes strong paper. (Kraft is German for strength. A German invented the Kraft pulp process in 1884.) A paper’s strength generally comes from the overlap and binding of long fibers of softwood; only chemically was it initially possible to separate long wood fibers for suspension in water. Hardwood fibers are generally smaller and thinner and help smooth the paper and make it less porous.

The ground wood pulping process was simpler and less expensive than the Kraft process. It took high quality spruce and fir logs and pressed them continuously against a revolving stone that broke apart the wood’s fibers. The fibers, however, were smaller than those produced by the Kraft process and, although used to make newsprint, were useful at Androscoggin in providing “fill” for the coated publication gloss papers of machines 2 and 3, as will be described later.

^(A)The chemical Kraft process worked by dissolving the lignin that bonds wood fibers together. ^(B) It did this in a tall pressure cooker, called a digester, by “cooking” the chips in a solution of caustic soda (NaOH) and sodium sulfide (Na²S), which was termed the “white liquor.” ^(C)The two digesters at Androscoggin were continuous digesters; chips and liquor went into the top, were cooked together as they slowly settled down to the bottom, and were drawn off the bottom after about three hours. ^(D) By this time, the white liquor had changed chemically to “black liquor’’; the digested chips were then separated from this black liquor. ^(E)

In what was known as the “cold blow” process, the hot, pressurized chips were gradually cooled and depressurized. A “cold liquor’’ (170°F) was introduced to the bottom of the digester and served both to cool and to transport the digested chips to a diffusion washer that washed and depressurized the chips. Because so much of the lignin bonding the fibers together had been removed, the wood fiber in the chips literally fell apart at this stage.

The black liquor from the digester entered a separate four-step recovery process. Over 95 percent of the black liquor could be reconstituted as white liquor, thereby saving on chemical costs and significantly lowering pollution. The four-step process involved (1) washing the black liquor from the cooked fiber to produce weak black liquor, (2) evaporating the weak black liquor to a thicker consistency, (3) combustion of this heavy black liquor with sodium sulfate (Na₂SO₄ ), and redissolving the smelt, yielding a “green liquor” (sodium carbonate + sodium sulfide), and (4) adding lime, which reacted with the green liquor to produce white liquor. The last step was known as causticization.

Meanwhile, the wood-fiber pulp was purged of impurities like bark and dirt by mechanical screening and by spinning the mixture in centrifugal cleaners. The pulp was then concentrated by removing water from it so that it could be stored and bleached more economically.

By this time, depending on the type of pulp being made, it had been between 3 1/2 and 5 hours since the chips had entered the pulp mill. 

All the Kraft pulp was then bleached. Bleaching took between 5 and 6 hours. It consisted of a three-step process in which (1) a mix of chlorine (Cl₂ ) and chlorine dioxide (CIO₂ ) was introduced to the pulp and the pulp was washed; (2) a patented mix of sodium hydroxide (NaOH), liquid oxygen, and hydrogen peroxide (H₂ O₂ ) was then added to the pulp and the pulp was again washed; and (3) chlorine dioxide (ClO₂ ) was introduced and the pulp washed a final time. The result was like fluffy cream of wheat. By this time the pulp was nearly ready to be made into paper.

From the bleachery, the stock of pulp was held for a short time in storage (a maximum of 16 hours) and then proceeded through a series of blending operations that permitted a string of additives (for example, filler clay, resins, brighteners, alum, dyes) to be mixed into the pulp according to the recipe for the paper grade being produced. Here, too, “broke” (paper wastes from the mill itself) was recycled into the pulp. The pulp was then once again cleaned and blended into an even consistency before moving to the papermaking machine itself.

It made a difference whether the broke was of coated or uncoated paper, and whether it was white or colored. White, uncoated paper could be recycled immediately. Colored, uncoated paper had to be rebleached. Coated papers, because of the clays in them, could not be reclaimed.

Need you now Lady Antebellum (2009)

Picture, perfect memories

Scattered all around the floor

Reaching for the phone 'cause

I can't fight it anymore

And I wonder if I ever cross your mind

For me it happens all the time

It's a quarter after one

I'm all alone and I need you now

Said I wouldn't call

But I lost all control and I need you now

And I don't know how I can do without

I just need you now

Another shot of whisky

Can't stop looking at the door

Wishing you'd come sweeping

In the way you did before

And I wonder if I ever cross your mind

For me, it happens all the time

It's a quarter after one

I'm a little drunk

And I need you now

Said I wouldn't call

But I lost all control and I need you now

And I don't know how I can do without

I just need you now

Oh ohh

Yes, I'd rather hurt than feel nothing at all

It's a quarter after one

I'm all alone and I need you now

And I said I wouldn't call

But I'm a little drunk and I need you now […]
