How to Make Cheese

MAIN INGREDIENTS OF CHEESE

The main ingredient used in the cheese making process is milk. Many types of cheese in North America are made from cow, sheep or goat milk. There are other varieties of milk used, however. The milk of a buffalo, for example, is used to produce Mozzarella cheese. Milk from deer, camel, horses, llamas, and yaks are all used to yield different varieties of cheese and cheese blends.

THE CURDLING PROCESS


Coagulating or curdling the milk until it turns into curds and whey is the first step taken when making cheese. Today, cheese is curdled with a bacteria culture and a coagulating enzyme, both of which help to speed the separation of liquids and solids. The curdling process begins by warming the milk until it reaches a bacteria-free temperature. During the warming period, a coloring dye is sometimes added to produce a particular color in the finished product. Once the milk has reached a consistent temperature, the starter culture is added and the milk begins to coagulate into one large curd.

REMOVING THE WHEY

As the milk forms into a huge curd, it is stirred and cut, allowing the whey to drain off. The milk is then reheated and pressed to remove as much whey as possible.

MOLDING AND SHAPING

when the whey removal process is finished, the warm curd is molded or shaped into a cheese. Many cheese today are shaped by using a cheese wheel or similar mold. The warm curd is poured and pressed into the molding.

SALTING PROCESS

High amounts of salt are added to cheese during or before the process of molding. Salt plays an important role in the formation of the cheeses rind or outer coating. Heavily salted cheeses will develop thick outer coatings, such as that found on swiss cheese.

RIPENING

Once the cheese has been molded and salted, it is allowed to ripen. Some cheeses take only two weeks to mature and others can take as long as 7-years. Temperatures remain exact during this time.

It is during this period when the rind of the cheese is formed. Some form naturally and others, artificially. Many cheese surfaces are treated with bacteria, alcohol, wax, oils, or water during the maturing phase to enhance flavor and coloring. Washed rind varieties, for example, are washed and brushed regularly to promote an even bacteria growth across the surface and prevent their insides from drying out. Cheddar cheeses are salted and then wrapped with cotton, after which time they are left untouched until they are mature.

CHANGES IN THE CHEESE MAKING PROCESS

Today, most types of cheeses are made in commercial factories, where state-of-the art equipment and technology prevent contamination and an overgrowth of bacteria. For food safety reasons, all cheeses are now made from pasteurized milk, instead of fresh milk.

CHEESE STORAGE TIPS

FOR OPTIMUM flavor, allow cold cheese to warm for 30-minutes before eating. Cheese can be placed on counter top during warming.

NEVER store cheese with heavy, strong smelling foods. Cheese will absorb the aroma of what is around it.

SOFT cheeses should be wrapped in wax paper and not plastic wrap.

Home made solar water heater




Who says Pepsi bottles are useless: Why not a solar hot water heater?










This Chinese farmer is getting hot shower water from this roof of Pepsi bottles and plastic tubing. This version of the story was seen on Ananova (sent in by reader Arnaud Betremieux). The account says “I invented this for my mother. I wanted her to shower comfortably,” says Ma Yanjun, of Qiqiao village, Shaanxi province.Ma’s invention features 66 Pepsi bottles attached to a board. The bottles are connected to each other [with plastic tubing] so that water flows through them.Sunlight heats the water as is passes slowly through the bottles before flowing into the bathroom as hot water, reports China Economy Network. Ma says it provides enough hot water for all three members of his family to have a shower every day.And more than 10 families in the village have already followed suit and installed their own versions of Ma’s invention.”

What Happens To The Rain


Rain, hail and snow are the means by which water is returned to the earth. If this did not happen then the survival of life would not be possible. What becomes of the rain When it has fallen? Some of it falls into the sea and becomes apart of it again. In this way it helps to replace the water that is always taken up into the air as water vapour.

Rain which falls on to the soil of flat areas sinks into it. It fills the small spaces between the grains of soil to a depth of several meters. This is the water that plants use. The roots and the tiny hair on them take up this water and pass it to the stem of the plant. It moves upwards to the leaves where it is used by the plant in its food-making process. The water in the stem and leaves helps to make them stiff too. The underground water makes an enormous water store that never completely dries up. Water that is used by plants, or is taken up into the air as water vapor (both from the surface of the soil and from the leaves of plants) is replaced by more rain.

Rain falls on hills and mountains as well as on flat ground. When this happens, the water begins to run down the hills in little rivulets. These rivulets join up and make a small, fast-running stream. Others join it on its way down until a river is formed. At places, where the ground slopes steeply, the river flows very quickly and tears a deep channel for it self. Later, as the ground becomes less steep, the river makes its channel wider but not so deep. It runs a little more slowly, too. When it reaches low ground, it runs much more slowly and its channel becomes full of twists and turns. In the end, the river reaches the sea and falls in it.

Sometimes rivers run over rocks made of limestone. These rivers may plunge down deep holes in the rocks and flow under the ground instead of on the surface. As it flows towards the sea, the water very slowly dissolves the limestone and makes tunnels and caves under the surface.

The Chinese New Year


The Muslims follow the Hijri Calendar. The first month is Muharram, which beings on the sighting of the moon. However, there comes a difference of ten days each year the moon completes its revolution round the earth contrary to the solar year.

The Hindus celebrate the season, and their festivals are connected with seasons of the year like spring, harvest time or the beginning of the rains.

The Christian Calendar (English Calendar) always starts on the 1st of January and ends on the 31st of December each year.

Although the Chinese follow the English Calendar as do all other people in the world. But according to the old Chinese traditions they have a cycle of twelve years, which is followed in the Chinese society only.

Each year is given the name of one of these animals: rat, ox, tiger, hare, dragon, snake, horse, goat, monkey, chicken, dog and tortoise. This cycle is completed in twelve years and then starts again. For example, if 1988 was the dragon year, the next year, that is, 1989 would be the snake year and so on.

Each Chinese month starts on the day of the new moon so that the full moon comes on the fifteenth day of the month. There are 29 or 30 days in each lunar month. They also have 12 months in a year and the new year always starts between January, the twenty first, and February, the twentieth.

Before New Year's Day, some traditional Chinese families clean out their houses very carefully. The female family members make many kinds of cakes and other sweet dishes. Everyday buys new clothes for the family feast on the New Year's Day. The Chinese people believe and hope that the sweet sticky juice cake will keep their kitchens stored with a lot of bread, rice and other food cereals.

The religious Chinese go to the temples to burn incense and other fragrant sticks and make offerings to their gods. Inside the house, bright red banners are stuck on the walls, saying, "May the rice jars be filled to the top with rice!"

Red is a favourite colour with the Chinese. They believe that red colour is for life, strength and valour.

On the New Year's Eve, there is a big family dinner. All the family members are invited to this dinner, and are supposed to be present there for the great meal, even if they have to travel many miles to reach the home of their parents. The Chinese do gather to have the meal their older genration.

Old quarrels and petty disputes are forgotten. Everybody tries to be the first one to forget quarrels and welcome the angry ones. Soon, all differences are settled and forgotten. The Chinese believe that all debts must be paid on the last day of the year. After the dinner, the children keep awake to welcome the New Year. Some people think that the parents will live longer if their children keep awake to greet the New Year. The lights switched on the New Year's Eve remain on for three to four days as good omen.

The New Year celebrations last for fifteen days from the new moon to the full moon. On the first day, the children and unmarried people go to visit their elders, and greet them with wishes for a happy, prosperous life. Often they give a cup of tea to their elders and receive red packets containing money.

The first meal on the New Year must not contain any meat. After the meal is over, people go to the temples to pray for peace, good health and give thanks for the happiness of the past year. Parents do not scold their children on the first day of the New Year, and avoid quarrels so that the New Year will be a happy one.

The Chinese people believe that the whole year will be as good or as bad as the New Year's Day and the harsh or rude words on this day will bring a bad year for them.

The house must not be swept out on this day, otherwise all the good luck will be swept away.

On the second day of the year there is a lot of fun and friends' visiting. Shops are opened on the second or forth day but remain closed on the third day and people stay at home. They think that opening of shops on third day will bring bad luck.

There is a great feast on the seventh day. The Chinese believe that man came into the world on the seventh day, so this is a birthday for everybody. People serve raw fish with vinegar and spices on the seventh day.

On the fifteenth day or the day of the full moon fire crackers are lit to frighten away evil spirits. In the evening young girls throw oranges into the sea or river. As they do this they say a silent prayer that will help them to find a good husband. The young men throw dried carrots into the river and pray that they find a good wife. The full moon shines on the land of the Chinese where the celebrations com to an end at mid night.

Save Nature

In our everyday life, water, air and land matter a lot. We drink water, breathe air and walk on land. We can tell whether the water we drink has a peculiar taste, is colorless or it has an odor which is unpleasant. The air we breathe has dust and smoke. The land we walk on is dirty and spoiled. All this is due to the fact that we are facing serious problems of pollution.

There are many types of pollution; water pollution, air pollution, land pollution and noise pollution. The fast growing population, increased number of factories and industries, and a large number of smoking vehicles are the main causes of pollution.

Water pollution takes place when it gets mixed with unclean and filthy matter due to poor drainage and sanitation system. Very often filthy water containing human and animal waste, and poisonous chemicals is mixed with drinking water. This dirty water is absorbed by land and reaches the underground storage of water. It is then supplied to public by the tube wells as drinking water. This dirty water also pollutes the nearby lakes, canals and rivers. Thus nature's main sources of ground and surface water are also affected.

Land pollution takes place when people dispose of their waste on the land. The improper disposal of the waste material results in a number of problems. When it rains, the rain water seeps through the soil. The waste dissolves and carries with it harmful materials which pollute the soil.

Air pollution is the most dangerous type of pollution and also very difficult to control. It is spread all over. Its effects on human health are wide ranging and very dangerous.

Noise pollution is also causing problems in the densely populated areas. Excessive use of vehicle horns and loud music beyond a safe level damages the ear drum. Environmental Protection Department is taking measure to control pollution. We, as citizens, most feel and take upon ourselves the responsibility to keep our environment clean which is also a religious obligation.

We most grow trees and protect the existing plants and trees. It is observed that most of the people clean their own places, houses and buildings, but throw garbage in the street or on the roads. It is the duty of each one of us to put the trash in the dust bins and keep our atmosphere clean.

Lever force to produce energy.

Hello friends have you any idea how much Energy can be produced through lever force.
First of all I want to tell you about "lever" . Next post will be about producing Energy.
In physics, a lever is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object. This is also termed mechanical advantage, and is one example of the principle of moments. The principle of leverage can also be derived using Newton's laws of motion and modern statics.
1 Early studies
The earliest remaining writings regarding levers are provided by Archimedes ("Give me a place to stand, and I can move the Earth.", a remark of Archimedes quoted by Pappus of Alexandria) who formally stated the correct mathematical principle of levers.

2 Force and levers
The force applied (at end points of the lever) is proportional to the ratio of the length of the lever arm measured between the fulcrum and application point of the force applied at each end of the lever. Mathematically, this is expressed by M = Fd.

3 The three classes of levers
There are three classes of levers representing variations in the location of the fulcrum and the input and output forces.

3.1 First-class levers



Examples:

Seesaw (also known as a teeter-totter)
Crowbar
Pliers (double lever)
Scissors (double lever)
3.2 Second-class levers



Examples:

Wheelbarrow
Nutcracker (double lever)
3.3 Third-class levers



Examples:

Human arm
TongsTongs are gripping and lifting instruments, of which there are many forms adapted to their specific use. Some are merely large pincers or nippers, but the greatest number fall into three classes: the first, as in the common fire-tongs, used for picking up ( double lever )

Solar Energy storage.

In this Article we will learn how to make storage energy produced by solar system.


Solar Two's thermal storage system generated electricity during cloudy weather and at night.

Solar energy is not available at night, and energy storage is an important issue because modern energy systems usually assume continuous availability of energy.

Thermal mass systems can store solar energy in the form of heat at domestically useful temperatures for daily or seasonal durations. Thermal storage systems generally use readily available materials with high specific heat capacities such as water, earth and stone. Well-designed systems can lower peak demand, shift time-of-use to off-peak hours and reduce overall heating and cooling requirements


Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 °C). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948.

Solar energy can be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 TJ in its 68 m³ storage tank with an annual storage efficiency of about 99%.

Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity. With grid-tied systems, excess electricity can be sent to the transmission grid. Net metering programs give these systems a credit for the electricity they deliver to the grid. This credit offsets electricity provided from the grid when the system cannot meet demand, effectively using the grid as a storage mechanism.

Pumped-storage hydroelectricity stores energy in the form of water pumped when energy is available from a lower elevation reservoir to a higher elevation one. The energy is recovered when demand is high by releasing the water to run through a hydroelectric power generator.

Solar Energy



This article is about all uses of solar energy. For generation of electricity using solar energy, see Solar power.



Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.

Solar power provides electrical generation by means of heat engines or photovoltaics. Once converted, its uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels and solar thermal collectors (with electrical or mechanical equipment) to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Energy from the Sun


About half the incoming solar energy reaches the Earth's surface.

The Earth receives 174 petawatts (PW) of incoming solar radiation (insulation) at the upper atmosphere.Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.

Earth's land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C By photosynthesis green plants convert solar energy into chemical energy, which produces food, wood and the biomass from which fossil fuels are derived.

and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined.

From the table of resources it would appear that solar, wind or biomass would be sufficient to supply all of our energy needs, however, the increased use of biomass has had a negative effect on global warming and dramatically increased food prices by diverting forests and crops into biofuel production. As intermitten resources, solar and wind raise other issues.

Darmstadt University of Technology in Germany won the 2007 Solar Decathlon in Washington, D.C. with this passive house designed specifically for the humid and hot subtropical climate.

Sunlight has influenced building design since the beginning of architectural history. Advanced solar architecture and urban planning methods were first employed by the Greeks and Chinese, who oriented their buildings toward the south to provide light and warmth.

The common features of passive solar architecture are orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass. When these features are tailored to the local climate and environment they can produce well-lit spaces that stay in a comfortable temperature range. Socrates' Megaron House is a classic example of passive solar design. The most recent approaches to solar design use computer modeling tying together solar lighting, heating and ventilation systems in an integrated solar design package. Active solar equipment such as pumps, fans and switchable windows can complement passive design and improve system performance.

Urban heat islands (UHI) are metropolitan areas with higher temperatures than that of the surrounding environment. The higher temperatures are a result of increased absorption of the Solar light by urban materials such as asphalt and concrete, which have lower albedos and higher heat capacities than those in the natural environment. A straightforward method of counteracting the UHI effect is to paint buildings and roads white and plant trees. Using these methods, a hypothetical "cool communities" program in Los Angeles has projected that urban temperatures could be reduced by approximately 3 °C at an estimated cost of US$1 billion, giving estimated total annual benefits of US$530 million from reduced air-conditioning costs and healthcare savings.
