In my last post, I am going to talk about the hydrogen cycle and the sulphur cycle.
Hydrogen is one of the constituents of water. It recycles as in other biogeochemical cycles. It is actively involved with the other cycles like the carbon cycle, nitrogen cycle ,sulfur cycle and oxygen cycle as well.
Firstly, Water is split into hydrogen and oxygen by the process of elecrolysis, using electricity generated from renewable energy sources. Secondly, The oxygen is released into the atmosphere, whilst the hydrogen is stored and transported. Thirdly, Oxygen from the atmosphere is re-combined with the stored hydrogen in a fuel cell, producing electricity and water vapour and fourtly, The water vapour is released back into the environment, where it can become part of the cycle once again.

Sulphur is one of the components that make up proteins and vitamins. Proteins consist of amino acids that contain sulphur atoms. Sulphur is important for the functioning of proteins and enzymes in plants, and in animals that depend upon plants for sulphur. Plants absorb sulphur when it is dissolved in water. Animals consume these plants, so that they take up enough sulphur to maintain their health.
We find many sulphur compounds on Earth. These include sulphur dioxide, elemental sulphur, sulphuric acid, salts of sulphate or organic sulphur compounds such as dimethylsulphide and even amino acids in our body. All these chemical compounds do not last forever. Most of the earth's sulphur is tied up in rocks and salts or buried deep in the ocean in oceanic sediments. Sulphur can also be found in the atmosphere. It enters the atmosphere through both natural and human sources. Natural recourses can be for instance volcanic eruptions, bacterial processes, evaporation from water, or decaying organisms. When sulphur enters the atmosphere through human activity, this is mainly a consequence of industrial processes where sulphur dioxide (SO2) and hydrogen sulphide (H2S) gases are emitted on a wide scale. All these particles will settle back onto earth, or react with rain and fall back onto earth as acid deposition. The particles will than be absorbed by plants again and are released back into the atmosphere, so that the sulphur cycle will start over again.
At the same time there are spatial / geographical cycles. One example is when sulphur compounds move from the ocean to the atmosphere, are transported to the land, come down with the rain and are transported by rivers to the ocean again.

The nitrogen cycle is the biogeochemical cycle that describes the transformations of nitrogen and nitrogen-containing compounds in nature. It is a gaseous cycle.
Earth's atmosphere is about 78% nitrogen, making it the largest pool of nitrogen. Nitrogen is essential for many biological processes; and is crucial for any life here on Earth. It is in all amino acids, is incorporated into proteins, and is present in the bases that make up nucleic acids, such as DNA(Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses) and RNA(Ribonucleic acid (RNA) is a nucleic acid and consists of a long chain of nucleotide units). In plants, much of the nitrogen is used in chlorophyll molecules which are essential for photosynthesis and further growth.
Nitrogen Fixation
The conversion of nitrogen (N2) from the atmosphere into a form readily available to plants and hence to animals and humans is an important step in the nitrogen cycle, that determines the supply of this essential nutrient. There are four ways to convert N2 (atmospheric nitrogen gas) into more chemically reactive forms. They are biological fixation, industrail n-fixation, combustion of fossil fuels and other processes.
Nitrogen Mineralization
In most ecosystems nitrogen is primarily stored in living and dead organic matter. This organic nitrogen is converted into inorganic forms when it re-enters the biogeochemical cycle via decomposition. Decomposers, found in the upper soil layer, chemically modify the nitrogen found in organic matter from ammonia (NH3 ) to ammonium salts (NH4+ ). This process is known as mineralization and it is carried out by a variety of bacteria, actinomycetes, and fungi.
Nitrification
Some of the ammonium produced by decomposition is converted to nitrate via a process called nitrification. The bacteria that carry out this reaction gain energy from it. Nitrification requires the presence of oxygen, so nitrification can happen only in oxygen-rich environments like circulating or flowing waters and the very surface layers of soils and sediments.
Denitrification
Through denitrification, oxidized forms of nitrogen such as nitrate and nitrite (NO2-) are converted to dinitrogen (N2) and, to a lesser extent, nitrous oxide gas. Denitrification is an anaerobic process that is carried out by denitrifying bacteria, which convert nitrate to dinitrogen. They use the nitrate as an electron acceptor in the place of oxygen during respiration. These facultatively anaerobic bacteria can also live in aerobic conditions.
Ammonification
When a plant or animal dies, or an animal excretes, the initial form of nitrogen is organic. Bacteria, or in some cases, fungi, converts the organic nitrogen within the remains back into ammonia, a process called ammonification or mineralization.
Assimilation
Plants can absorb nitrate or ammonium ions from the soil via their root hairs. If nitrate is absorbed, it is first reduced to nitrite ions and then ammonium ions for incorporation into amino acids, nucleic acids, and chlorophyll. In plants which have a mutualistic relationship with rhizobia, some nitrogen is assimilated in the form of ammonium ions directly from the nodules. Animals, fungi, and other heterotrophic organisms absorb nitrogen as amino acids, nucleotides and other small organic molecules.
Currently, much research is devoted to understanding the effects of nitrogen enrichment in the air, groundwater and surface water. Scientists are also exploring alternative agricultural practices that will sustain high productivity while decreasing the negative impacts caused by fertilizer use. These studies not only help us quantify how humans have altered the natural world, but increase our understanding of the processes involved in the nitrogen cycle as a whole.

The carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange.
These reservoirs are the atmosphere, the terrestrial biosphere, which is usually defined to include fresh water systems and non-living organic material, such as soil carbon, the oceans, including dissolved inorganic carbon and living and non-living marine biota and the sediments including fossil fuels.
Carbon is an element. It is part of oceans, air, rocks, soil and all living things. Carbon doesn’t stay in one place. It is always on the move! The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant, the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately, the extent of its importance is rarely stressed enough. Without the proper functioning of the carbon cycle, every aspect of life could be changed dramatically.
Carbon moves from the atmosphere to plants
In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). With the help of the Sun, through the process of photosynthesis, carbon dioxide is pulled from the air to make plant food from carbon.
Carbon moves from plants to animals
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Example:
Plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make the substances they need for growth. The process of photosynthesis incorporates the carbon atoms from carbon dioxide into sugars.
Animals, such as the rabbit pictured here, eat the plants and use the carbon to build their own tissues. Other animals, such as the fox, eat the rabbit and then use the carbon for their own needs.
Carbon moves from plants and animals to the ground
When plants and animals die, their bodies, wood and leaves decay bringing the carbon into the ground. Some becomes buried miles underground and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere
Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned
When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. That’s the weight of 100 million adult African elephants! Of the huge amount of carbon that is released from fuels, 3.3 billion tons enters the atmosphere and most of the rest becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans.
The oceans, and other bodies of water, soak up some carbon from the atmosphere.
Ultimately, the same carbon atom can move through many organisms and even end in the same place where it began. Herein lies the fascination of the carbon cycle; the same atoms can be recycled for millennia!

In this post, I am going to continue on global warming. Not only is aquatic animals affected by global warming but also birds.
The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns and because of this, migratory birds are greatly affected.
The results of several studies investigated show that as the temperatures becomes warmer, migrant species in temperate latitudes, such as the Pied Flycatcher (Ficedula hypoleuca) also arrive on their breeding grounds earlier than expected stated CMS in a release. Scientists have also been studying the dates on which red-winged blackbirds arrive in northern Michigan, found that warming temperatures have dramatically altered the birds' migration as they now arrive 21 days earlier than they did in 1960. The timing of migrations is critical to the survival of numerous bird species. Beginning their journey too early or late may mean that birds miss the food sources they need to survive. As a result of this, migratory birds are travelling thousands of miles only to find the insects they depend on had their breeding cycle a few weeks earlier based on the temperature rise.
Early spring might lead to a shift in the prey (insect hatching) or a shift in vegetation bloom. Unfortunately these shifts are not in line and may occur before the young birds hatch. As a result the birds may not provide enough food for their offspring.
Hence, please do your part to help the earth, these animals and most importantly YOURSELF by helping to slow down the process of global warming and cooling the Earth! =)

In this post, I will be touching on the oxygen cycle.
The oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within and between its three main reservoirs: the atmosphere (air), the biosphere (living things), and the lithosphere (Earth's crust). The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's atmosphere and life.
Just as water moves from the sky to the earth and back in the hydrologic cycle, oxygen is also cycled through the environment. Plants mark the beginning of the oxygen cycle. Plants are able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. This means that plants "breathe" in carbon dioxide and "breathe" out oxygen. Animals form the other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.
The photosynthesis takes place in the green plants, whereas the aerobic respiration takes place in all living organisms. The oxygen cycle is determined by the aerobic respiration of glucose, which consumes oxygen and produces carbon dioxide and water, and by the photosynthesis, which consumes carbon dioxide and water to produce organic matter (sugars) and molecular oxygen.
Carbon dioxide produced during respiration is breathed out by animals into the air, so oxygen is created in plants and used up by animals, but the oxygen cycle is not actually quite that simple. Plants must break carbohydrates down into energy just as animals do. During the day, plants hold onto a bit of the oxygen which they produced in photosynthesis and use that oxygen to break down carbohydrates. But in order to maintain their metabolism and continue respiration at night, the plants must absorb oxygen from the air and give off carbon dioxide just as animals do. Even though plants produce approximately ten times as much oxygen during the day as they consume at night, the night-time consumption of oxygen by plants can create low oxygen conditions in some water habitats.
In conclusion, in the day, photosynthesis produces oxygen which is taken in by humans and animals for respiration and carbon dioxide is given out during repiration and is taken in for photosynthesis. In this way, the oxygen and carbon dioxide can be "reused" and thus forming a cycle.

Qns: How many cycles are there in the world and what are they used for? Are they helpful to us?
In ecology and Earth science, a biogeochemical cycle is a circuit or pathway by which a chemical element or molecule moves through both biotic ("bio-") and abiotic ("geo-") compartments of an ecosystem. In effect, the element is recycled, although in some such cycles there may be places (called "sinks") where the element is accumulated or held for a long period of time. There are many different types of nutrient cycles. They are water, oxygen, carbon, nitrogen, phosphorus, sulfur and hydrogen. In this post, I am going to talk about the water cycle.
The Earth's water is always in movement, and the water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Since the water cycle is truly a "cycle," there is no beginning or end. Water can change states among liquid, vapor, and ice at various places in the water cycle, with these processes happening in the blink of an eye and over millions of years.
This cycle is made up of a few main parts. They are evaporation (transpiration), condensation, precipitation and collection. This is how the cycle goes. The Sun, which plays a major role in the water cycle, produces energy in the form of heat and causes the water in the water bodies such as oceans, rivers, canals and even the puddle in your backyard to evaporate. Transpiration is also involved as it is the process by which plants lose water out of their leaves. Transpiration gives evaporation a bit of a hand in getting the water vapour back up into the air. When the water gets heat, it forms water vapour which condenses in the cool air, changes into liquid and forms clouds.
As more and more water vapor cools into the clouds, the water droplets that form the clouds become larger and larger. These droplets get so big that the swirling winds in the atmosphere can no longer hold them up. The droplets fall from the sky. Precipitation is the term for the falling, condensed water molecules, which come down as rain, snow, sleet, or hail--depending on conditions in the atmosphere. When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.

Qns: How has global warming destructed and detroyed some parts of the beautiful Earth?
Global warming has caused a destruction in polar bear's lives as it continues to melt the ice caps.
In southern portions of their range, such as Hudson bay and the Artic, the ice is melting vastly and quickly. When it is summer, the polar bears stay on land and do not hunt or even eat anything as they wait till there is ice before they hunt animals and continue their diet. In just 20 years the ice-free period in Hudson Bay has increased by an average 20 days, leaving nearly three weeks less time each year for the bears to hunt for seals on the ice.
In this case, they have lesser time to hunt for animals as the heat in the air increases. As a result, the bears are skinnier and have lower reproductive rates than when the ice persisted throughout the seals’ birthing period. As average bear weight has dropped by 15%, reproduction has declined and the population is down more than 20%.
Already, more than 25 percent of the world's polar bear populations are in decline and evidence of the dire impact of global warming on polar bears continues to mount. That evidence includes polar bear drownings, cannibalism, starvation, reduced cub survival and denning dislocation. So do your part to help and hold back global warming!
Rise in localised Arctic surface temperatures over last 50 years--->4°C
Extra ice melted between 1978 and 2005-1.3 million km² ---> an area five times the size of the UK

In this post, I am going to talk about prevention of epiglottitis.
The bacterial infection that usually causes epiglottitis is easily passed between close contacts, so if one family member has this condition, the others should be immediately screened by their GP or hospital doctor. Household members may be given an antibacterial drug, such as rifampin, to prevent further infection, especially if there are other young children in the family. Prevention of epiglottitis can be achieved with proper vaccination schedules against H influenza type b (Hib) and pneumococcal infections. Therefore it is important that your doctor make the appropriate recommendations for vaccination against Hib.
Haemophilus influenzae type b vaccine (Hib vaccine or PRP vaccine) is a conjugate vaccine developed for the prevention of invasive disease. Pneumococcal conjugate vaccine or Prevnar is a vaccine used to protect infants and young children against disease.
In the next post, I will start on Ecology.

In this post, I am going to talk about the treatment of epiglottitis and follow ups in treatment.
Immediate medical help is required whenever there is a diagnosis of epiglottitis as the victim may be in danger of sudden and unpredictable closing of the airway. It may also turn out to be fatal if the patient is not given immediate medical help. If there are no signs of respiratory distress, IV fluids may be helpful. It is important to prevent anxiety because it may lead to an acute airway obstruction.
It may be necessary to insert a tube into the windpipe under general anaesthetic to keep the airways open, allowing oxygen to get to the lungs and in very severe cases, the doctor may need to perform a cricothyrotomy (cutting the neck to insert a breathing tube directly into the windpipe). The patients would be given antibiotics and humidified oxygen (oxygen that has been moistened) is given to help the patient to breathe.
The patient must regularly intake antibiotics and go for follow ups with their doctor. If a breathing tube is to be placed in the neck, follow ups with the surgeon is needed to take out the tube and make sure the site is healing well.
In the next post, I will talk about how to prevent epiglottitis.

I am going to start and talk about Ecology and nutrient cycles.
As all of you know, global warming has caused a great and huge effect on the ecosystem. More and more glaciers and ice caps are dimishing effectively as there is a rise in temperatures. According to many reports, by 2040, the Artic could be ice-free. This has created many problems for animals living in the Artic like polar bears and penguins. The polar bears have to swim and swim till they can find huge ice caps where they can stay on for a few weeks before moving on to find others. They also swim around to find food.
While searching for ice caps, the polar bears may drown as they become tired when they swim huge distances. Although polar bears are strong swimmers, they are adapted for swimming close to the shore. Their sea journeys leave them them vulnerable to exhaustion, hypothermia or being swamped by waves. Such drownings are becoming widespread across the Arctic, an inevitable consequence of the doubling in the past 20 years of the proportion of polar bears having to swim in open seas.

In this post, I will talk about epiglottitis causes and its symptoms.
The epiglottis is a small flap of tissue that hangs down from the upper part of the back of the throat. It may also become infected sometimes. Epiglottitis is very sudden and can be fatal!
Epiglottitis is caused by bacteria infection of the epiglottis, viruses and fungi. The bacteria that are most commonly involved include Haemophilus influenzae, pneumococcus or Streptococcus. Conditions that cause epiglottitis include infectious, chemical, and traumatic agents. The epiglottis can also be injured by trauma and may swell up in allergic reactions.
Here are some signs and symptoms of epiglottitis. They include sore throat, muffling or changes in the voice, difficulty speaking and difficulty swallowing. As the swelling worsens, there can be difficulty swallowing and drooling can occur. When the epiglottis enlarges enough to compromise the airway, breathing difficulty can develop. The victims may also lean forward to breathe, drool, appear restless and ill and have fever. As breathing becomes more difficult, the tongue is stuck out, the nostrils flared and the skin, nails and lips appear dusky or purple. Lack of oxygen can lead to confusion, agitation, stupor and coma.
In the next post, I will talk about the treatment of epiglottitis and follow ups in treatment.

Today, I am going to talk about the functions of esophagus and what is epiglottitis.
The function of the esophagus is to transport food and liquids into the stomach, where it will digest the food and the nutrients can be absorbed by the small inestine and the waste will be excreted by the large intestine.
Can the food come out from the stomach and go back into the esophagus and back to the mouth? The answer is no. The muscular layers of the esophagus are normally pinched together at both the upper and lower ends by muscles called sphincters. The sphincters allow food and liquids to pass through as it relaxes. As the food moves down, the muscles close rapidly in order not to allow the food or liquid to go back into the esophagus or even the mouth.
The next thing i will talk about will be epiglottitis. Epiglottitis is inflammation of the epiglottis - the flap that sits at the base of the tongue, which keeps food from going into the trachea (windpipe). Due to its place in the airway, swelling of this structure can interfere with breathing and constitutes a medical emergency. The infection can cause the epiglottis to either obstruct or completely close off the windpipe. It can also be fatal if not treated immediately.
In the next post, I will talk more about epiglottitis causes and symptoms.

In this post, I am going to talk about esophagus, which contributes greatly to the digestive system.
The esophagus, sometimes known as the gullet, is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. (The pharynx is the part of the neck and throat situated behind the mouth and nasa cavity.
One question I wanted to ask is: What is the purpose of having to eat and swallow your food, in the same orphis that you breathe through? It seems like you would be determined to choke at some time or another.
I researched and found this info. There have a structure in your throat called an epiglottis. The function of the tissue is to cover your trachea as your eating and drinking. Thus preventing food from getting in your trachea and directing it into your esophagus. It works pretty well at preventing choking.
In the next post, I will talk more about esopahgus and epiglottis.

In this post, I will talk about Argyria.
Firstly, I will start with the meaning of Argyria. Argyria is a condition caused by the ingestion of elemental silver, silver dust or silver compounds. Argyria results from prolonged contact with or ingestion of silver salts. Argyria is characterized by gray to gray-black staining of the skin and mucous membranes produced by silver deposition. Silver may be deposited in the skin either from industrial exposure or as a result of medications containing silver salts.
To treat it, you can use hydroquinone treatment as it may reduce the number of silver granules in the upper dermis and around sweat glands and diminish the number of melanocytes or Chelation which attempts to remove silver from the body or sunscreens and opaque cosmetics which may help in preventing further pigmentary darkening and aid in masking obvious discoloration.
