Dust & Dust Mites

Dust
Those little grey particles of hair, sand, and.. well, 'dust' that inhabits almost every corner of every house, and hides in those un-reachable nooks and crannies. Most of this dust, however, is made up out of the 30,000 to 40,000 dead skin cells that we lose every minute! There's also the mold, ash from smoke, bacteria, animal fur etc....
All in all, not everyone's favourite substance!


Yes, that's right. This is mostly dead skin!
It's found everywhere, from 'dust-storms' to abandoned buildings to just happily floating around minding its business. A lot if this is dead skin, too, as dead skin accounts for about a billion tons of dust in the atmosphere. Woo! You're inhaling human sheddings. :D


But enough about that stuff!
Let's talk about something even more skin-crawling! (literally)

Dust Mites

These are the little, teeny, microscopic arachnids that live happily in the stuff we so despise.
They are also one of the reasons my skin is perpetually covered in eczema! (Something they're quite famous for! But then again, my skin is just generally really keen to tear itself from me. XP)
In fact, it's these mites, not the commonly-believed pollen, that is one of the most persistent sources of allergic reactions! (60%!)
Though, in actual fact, it's not the creatures themselves that we're allergic to, but their fecal material and cast skins. 

dust mites in a group

These adorable (or not so) little less-than 1/2 a millimetre long creatures love to live and multiply in places where you humans spend most of your time!
...That's right!
I'm talking about your bed, (especially your pillow, as they love to eat dandruff) your sofa, and wherever you spend lots of time! 
They also like a bit of moisture and humidity - another reason why they love your bed, and live happily in highly-humid, warm places. 


Now you may think "I'm going to have to change my duvet / pillows more often now! D:"
...however, these mites spread very rapidly and will be found spread in a new mattress as fast as six months after purchase. Not to mention that they can move around airborne with simple activities such as changing bedding and shaking pillows, and so will just hop from one to the next.
There is SOMETHING you can do, though, as washing your bedding in hot water once a week removes dust mite populations. Not much point in doing this though, unless you are EXTREMELY allergic, or just really creeped out at the thought of the around 500,000 dust mites that approximately inhabit your home.

dustmites feeding on your dead skin
Yep. 500,000 of THESE.
Life-Cycle
These teeny spider-mites have a lifespan of around four months. The cycle from egg to larvea to adult takes about a month, with the adult living for about three.
In this short period, the female dust mite can lay as many as 100 eggs in her lifetime in small groups of three to five. 


Anywho!
I'm off to bed. G'night all, sleep well. ^^
Dragina, awaayyyy!~ ^.=.^

Swans

Swans - The "Royal Bird"

I need only say the word "swan" and one immediately imagines one of the beautiful, white royal birds that have been so loved for many years.



There are around seven species of swan, but the four most common and recognised species are the Mute swan, the Black swan, the Black-necked swan and the Tundra swan.


Swans
Look! I found pictures of them! ^^
Today, however, I'm going to focus largely on the Mute swan, (Cygnus olor) as they are by far the most well-known and recognised type. (Seriously. Type "Swan" into Google images and about 85%ish of them are the mute swan!) They are also the type that we love to see drifting gracefully across lakes, of gliding through rivers on a bright spring morning. 





The Life of a Swan


Swans generally mate for life, only replacing their partners if they are lost or dead. Courtship begins between the ages of 2-4. This is done by displaying, or showing off to another swan (like most bird species!). While facing each other they dip and turn their heads. Swans may also “kiss” bills, creating the heart shape with their necks that the species is renown for.

It DOES look very much like a heart!
Nests are usually a wide mass of rushes and reeds, lined with down and built near the water's edge. The female lays two to seven whitish eggs, each about four inches (10 cm) long.When hatched, baby swans, (called cygnets) are known to be rather ugly (or at least very different from their white parents!) - see "The Ugly Duckling".

Aw, how can you call this ugly!?
After 5 weeks of incubation the cygnets finally hatch, being able to swim as soon as a day or two after hatching. Their parents will protect them for their first few months of their life; which is the reason it's best to stay away from nesting grounds during this period... parents tend to be rather aggressive!




The cygnets are independent in about 18 weeks, and ready to fly in 4 to 5 months when they may leave their home territory. However they are only considered fully grown in size after about 6 months.Then, another 6 months later, the young will finally have that oh-so desirable white adult plumage!In any case, if they don't leave to find their own territory, they will be driven off by their parents before the next breeding season. Like a lazy teenager being kicked out of the house. XD


Domestication of Swans

For many centuries, mute swans in Britain were domesticated for food!Individual swans were marked by nicks on the webs of their feet or beak to indicate ownership. These marks were registered with the Crown and a "Royal Swan herd" was appointed. Any birds not so marked became Crown property, hence the swan becoming known as the "Royal Bird". It is quite possible that this domestication saved the swan for being hunted to extinction in Britain. 

 



Other Swan Info!


Swans are the largest water fowl on Earth,  Mute swans weighing from 6.5 – 13 kg (14 – 30 pounds), and about 160 cm (5 feet) long, with a wingspan up to 2.5 meters (8 feet).A male swan is called a cob, and a female swan is called a pen.The Mute swan’s neck has more vertebrae than any other bird: 23,  as well as boasting some 25,000 feathers that make up its impressive plumage.Swans are actually very intelligent; being able to recognise humans who have been nice -or cruel- towards them. They do not attack humans without cause. (But can be aggressive during nesting!)The Mute swan is not actually mute! They can make a variety of hissing and occasionally honking (or 'barking'/'bleating') noises as well! (Talk about a misleading name!)

Overall, we've got to agree that swans are pretty awesome birds. (Both literally and figuratively! XD)

Anywho! Hope you enjoyed all that stuff on swans!

The Chinese Gold Miners

Ok, I don't have time or motivation to write a post. I had a very upsetting day and don't have it in me to write a proper post so here's my history project, I hope you like learning about the chinese miners! ^.^ (Just so I don't get in trouble, DO NOT COPY THIS WORK FOR ANY ASSESSMENTS!!!) DFTBA! :)

The Chinese Gold Miners in New Zealand
Why were the Chinese invited to work in New Zealand?

Many Chinese miners were working in Australia after gold was discovered there in 1851. This led to an influx of immigrants into Australia and most of these immigrants were Chinese workers seeking to make enough money to sustain their life style whilst still sending money back to China to sustain their families back home and provide them with a better lifestyle than would have been possible form working in China.

There was a great deal of tension between the Australian miners, the European miners and the Chinese miners. This was primarily due to the significant cultural differences between them. The Chinese tended to live in close communities which meant they rarely associated with the European miners. The Chinese preferred to smoke opium rather than to drink alcohol and gamble which was what European miners tended to do in their spare time. The difference in culture resulted in the European miners abusing the Chinese, both verbally and sometimes even physically. There were some notable violent attacks and riots such as the 1860-1861 Lambing Flat riots, where protestor’s used physical violence to push the Chinese out of their settlements. The Australian government was unable to provide support and protection for the Chinese miners and this led to the miners resenting working in Australia.

Gold was first discovered in New Zealand in 1861. Once the discovery was announced in the Otago newspaper, the news of the find spread rapidly around New Zealand and miners started to flood into the Otago gold fields. This discovery was a huge boost to the New Zealand economy. However the chamber of Commerce was aware of the situation in the gold fields in Australia and realised that ten Chinese immigrants had been the biggest boost to the Australian gold mining industry and hence a large reason for the increase in the Australian aconomy.so when after the first few years of gold mining in Otago, the European miners thought they had exhausted most of the available gold, the Chamber of Commerce sent a notice to China and Australia inviting Chinese miners to New Zealand to mine for any remaining gold they could find. These notices promised protection to the Chinese.

In the late 1800s, early 1900s New Zealand was relatively unknown and it was thought to be a relatively peaceful and law abiding country with little violence. This appealed to the Chinese as they saw an opportunity to mine on a far safer environment than Australia. Shortly after the notice was issued, the Chinese population rose from almost zero to about 1,200 in Otago alone.

The Chinese lifestyle


Most of the Chinese miners in New Zealand lived a similar lifestyle to those in Australia. They either lived in tight knit communities with others from the same ethnicity or on their own in a cottage on the edge of a township. This was because many of the Chinese miners, whether they were from Australia or directly from China, had left their families back home in China. Some men brought over one relative but this was usually a male who would be able to help with the mining work. This resulted in many of the Chinese miners becoming very lonely which in turn resulted in strong communities forming with a strong sense of unity and solidarity.

The majority of the miners could not afford to bring their families over from China as the fare was too high. Only the wealthier families managed to pay the fare. These families tended to establish shops or other small businesses, generally specifically tailored to meet the needs of the wider Chinese community.

The European miners did not mix with the Chinese as they felt uncomfortable about their lifestyle which was deemed to be “weird” and foreign. In addition to their secluded lifestyle, the Chinese also mined in a different way to the Europeans which further differentiated them. The Chinese tended to re-mine old claims which had been abandoned by the European miners. The European miners had taken all the “easy” gold which was relatively easily mined and they left the gold which was harder to extract and therefore less profitable. The hard working Chinese miners were not afraid to work for this gold and it provided them with a reasonable income and hence lifestyle, whilst allowing them to send money home to their families in China. It was unlikely they would ever become wealthy this way though. The Europeans miners could not understand the Chinese approach to mining: their aim was to get rich quickly and move on. This uncommitted type of mining style favoured by the Europeans meant they often went without food and did not have a very comfortable lifestyle.

Since the Chinese were working previously worked European claims, conflicts often arose when the Europeans returned to their old claims to finds that they had lost them to the Chinese. This also created tension between the two cultures.


What were the New Zealander’s views of the Chinese?

 The European miners strongly resented the Chinese miners as they felt they stole their claims and were too “exclusive”. These views prevailed throughout New Zealand and even through the families of the miners themselves. These views were also enhanced by the fact that many Chinese established farms and other agricultural businesses. Many New Zealanders felt that the influx of the Chinese threatened their sovereignty over New Zealand. The New Zealanders could see the Chinese were willing to work harder than they were for less pay and this made them more favourable employees to the New Zealanders. The New Zealanders felt that businesses were more likely to employ the Chinese workers and this, together with the rise in the number of Chinese businesses, worried the New Zealanders who felt that they were losing out on securing jobs. The New Zealanders felt that the jobs should be given firstly to them to maintain national sovereignty. The Chinese started to become known as “The Yellow Peril”.

In 1871, the extent of discontent with the Chinese situation led to the signing of a petition requesting the New Zealand Government either restrict Chinese entry into New Zealand or deport the Chinese who were not New Zealand citizens. Whilst the Government was prepared in general to listen to New Zealanders to prevent violence erupting, the Chamber of Commerce did not want the Government to amend the legislation. The Chamber had been tracking the significant rise in the economy and it was no coincidence that the rise correlated with the arrival of the Chinese. With the Chamber’s strong objection to any changes being made to the legislation, the Government felt obliged to retain the status quo to maintain long term economic gains. The rejection of any amendment further increased tension between the Chinese and the New Zealanders.

How did this lead to the miners being treated differently?

 With tensions between the Chinese and the Europeans being at an all-time high, violence was bound to break out. A famous example of this violence occurred in 1905when an elderly Chinese woman was fatally shot by activist Lionel Terry in Wellington’s city centre. There were several other similar incidents around the country. However, the violence and discrimination was not merely centralised towards individuals but was often directed at a whole group of Chinese. At this time the town considered to be “the gateway to the goldfields” was a small town called Lawrence in Otago. Any Chinese who chose to live there was shunned and excluded. Some shops even refused to sell goods to any Chinese living in the town. This forced the Chinese to establish their own township a kilometre away. The Chinese felt secluded and strong resentment grew among them which in turn led the Chinese community to becoming wary and unaccepting of the New Zealanders. The two racial groups kept to themselves and did not inter mixed. This split the mining communities into two which worried the New Zealand Government which had originally promised to protect the Chinese mining community. However it was also the Government’s duty to protect their own citizens. In 1881 the New Zealand Government finally bowed to pressure from the New Zealanders and in an attempt to appease them and put a stop to the violence which was escalating, they passed legislation restricting Chinese entry into New Zealand.

What did the New Government do about the problem?

The New Zealand Government enacted legislation to restrict Chinese entry into New Zealand. The main piece of legislation was the Act “To regulate the Immigration of Chinese. “This came into force in late 1881 and stated that in order to enter New Zealand a person of Chinese ethnicity had to pay a poll tax of £10 to the New Zealand government. In addition, ships carrying Chinese immigrants were only permitted to carry one person of Chinese ethnicity per 10 tonnes of cargo. This excluded Chinese sailors from remaining in New Zealand for any length of time. The penalty on a captain who floated the law was £10 per Chinese person carried in excess of the allowance.

At first this legislation settled tensions between the Chinese and the New Zealanders. However, it was soon realised that the influx of Chinese into New Zealand had only decreased in a minor way following ten introduction of this legislation. This resulted in the New Zealanders becoming furious with the Government as they felt it was trying to cheat them of jobs that were rightfully theirs as citizens of New Zealand. This placed pressure on the Government to raise the level of the poll tax. Once again the Chamber of Commerce came out against any increase in the tax on the basis that the Chinese were a positive influence on the New Zealand economy and the more allowed into New Zealand the better. A rise in the poll tax would deter immigrants.

In the end the Government decided to ignore the Chamber’s wishes and give in to the New Zealand public in an attempt to prevent violence. In 1896 the poll tax was increased to £100. Following this huge increase, the influx of immigrants decreased significantly and the majority of the New Zealand population felt appeased.

After the significant rise in the poll tax, most of the tension between the Chinese and the New Zealanders eased. Although the resentment, exclusion and occasional violence were still apparent, most of the prejudice had dissipated. During the early 1900s the gold began to run dry in the Otago fields. By this time, many of the New Zealand miners had left Otago for the West Coast of the South Island, leaving the Chinese to fully exhaust the remaining gold fields, especially in the rivers.
After so many years away from home, most Chinese miners were anxious to return to their families. However a passage on a boat to China was expensive and beyond the financial means of most miners who in general only made enough to live on and to send money home. This resulted in most of the miners remaining in New Zealand. Some established small businesses, some of which are still operating in Otago today. Most of the miners left these communities which became abandoned and they built small cottages in remote locations around Otago.
In the past several decades some of the bodies of the Chinese miners have been transported back to their homeland and returned to their families. The remainder are buried in graveyards here in specifically designed plots.
Many historical gold mining sites remain today and tourists are able to gain a glimpse into how the Chinese lived and worked. A memorable site is that of the remains of a cottage which belonged to a Chinese miner, unable to return to his homeland. This cottage can be seen on the way in to Macetown in Otago near Arrowtown. The Chinese man who lived there is reported to have been an opium smoker and the site is known as “Opium Bob’s cottage”. Similar sites to this can be seen in many other places around Otago. There is a relatively large settlement in Arrowtown, down by the Arrow River and another along the Kawarau gorge Road between Queenstown and Cromwell. The derelict cottages can be entered. They generally consist of a small single room with a fireplace and a bed. The walls are usually of stone and the floor is bare dirt.

What is the result of Chinese miners’ immigration in New Zealand today?

Many historical sites have been restored and set up as tourist sites. These sites show visitors how Chinese miners lived and worked and the conditions they endured to make a living and send money home to their families back in China, who many never saw again after arriving in New Zealand.
Recently the New Zealand government has sought to return some land to the Chinese and their descendent families. However to date no returns have been made as no direct descendants have been found.
Helen Clarke, on behalf of the New Zealand government made a public apology to the Chinese Government for the appalling treatment of the Chinese immigrants in New Zealand. This apology was made in any attempt to from strong economic and social ties between the two countries. It has also highlighted the plight of the Chinese miners to the New Zealand public and has led to understanding of the suffering endured by the Chinese 100 years ago. The Chinese immigrants suffered prejudice and racism some of which is still present today.
New Zealanders today have recognised that New Zealand was considered a racist country and the Government has, in the past 150 years, acted in a racist manner. Has this led to a better and more tolerant society in New Zealand with more acknowledgment of the need to understand and incorporate different cultures into our society?  It may have paved the way for a more understanding society tolerant of different races. It may have taught New Zealanders to be more tolerant of other races and the benefit of working together for economic gain.
There are many Chinese in New Zealand today, working and assisting in the economic prosperity of our country.
It has resulted in a number of tourist attractions which provide economic return for the country.

The Human Eye

The Human Eye

The second most complicated organ in our body, (the brain takes first) the eye is to be thanked for over 85% of what we experience every day and work tirelessly and without rest their entire lives. (external muscles  need rest though, and lubricant must be replenished. The eye, itself, however, needs no rest.) 



We use our eyes almost constantly every day, (aside from the average of 10 000 blinks a day and sleeping) and yet we barely ever think about the fact we're using them. We're far too engrossed by the 36,000 bits of information we are receiving every hour, and the around 50 things a second our eyes focus on for us to think about the processes that the images we see have to go through.

We actually see everything upside-down, but our wonderful brain flips it the 'right' way up for us, not to mention fading the two different images (one from each eye) that its given together! But that's the brain, and another topic.

Colours

With aroun120 million rods for “night vision”, and 8 million cones that are colour sensitive (and work best in light) be are able to distinguish between over 500 shades of grey, and see over 2.7 million different colours.



However, not everyone has this privilege. Roughly 8% of men and 0.5% of women are affected by at least some form of colour-blindness.
There are quite a few variations of this, though! It's not just black and white!
The most common type of colour-blindness is the 'red-green' type called deuteranopia, however, very rarely, There are people which are really suffering from complete color blindness, which is called achromatopsia or monochromacy.

Other little facts

Only 1/6 of our eye is actually 'exposed'. However, humans are still the only animal which has the 'whites' of our eyes showing. 
See? No eye-whiteness!

Another misconception is that there is only one colour-gene coding for our eyes.
Actually, there are three!
We've got an allele for a colour in our inner ring, centre, and outer rings of the iris.
This is why you'll occasionally meet people with multi-coloured eyes, as opposed to just monochromatic all the way!




But, overall, the human eye is a ridiculously powerful, awesome, and pretty organ! Humans have been and still are obsessed with them! (Seriously, just google-image 'eye' and you'll get thousands of photos, (photoshopped and real!) images of them.)
If you can see, (with the aid of glasses or not!) be happy that you have such a complex organ functioning in your body! ^-^

Popularity


Popularity

It is the doom of some people and what others pride themselves on. I have broken the ‘popularity ladder’ into sections. Here’s what I think:

1.       Ultra popular – The ones who can be very selective of their friends and the ones who ‘everyone likes’. Though personally I don’t think this is true because I only genuinely like 3 of the ultra popular people in our year.

2.       Nice popular – these people are generally smart and people who everyone like. Several of my friends fall into this category. These people are one step down because not everyone knows them and they are less outgoing. Severally people I know in this category are ‘nice’ but rather exclusive.

3.       Popular within several groups. These people are well known however less so than the groups above them, however they are part of several friend groups and are very popular within these groups.

4.       Popular within their own group. These people are popular within their own group and just their own group, they are little known.

5.       In a group. These are the people that fit into a friend group but aren’t one of the ‘key members’ of that group.

6.       Awkward member of their group. These people normally hang out in the library or something but when they hang out with their group they are a bit of an awkward wheel.

7.       Mr/ Mrs Unpopular. These are the people who to be honest nobody likes because whilst the may be nice they have no social skills. These people are often selfish and unable to hold normal conversations, they also tend to randomly butt in on conversations they are not part of (this is really annoying).

So if you want to boost yourself up the social ladder one needs to be confident and learn good social skills and I’m sad to say this but give some consideration to their appearance.  However if you are in 5, 6 or 7 I recommend you always think twice or thrice before you say something! Popularity isn’t everything, at this stage grades are and I recommend you have nice friends who care about you for who you are.

Sorry for the short post… maths test tomorrow which I should start studying for! :P
If you have any questions about popularity so leave questions in comments! :)

DFTBA!!
