Art in Oceania

Posted on 30th December 2010 by squadron in Uncategorized

The visual art and architecture of native Oceania, includes media such as sculpture, pottery, rock art, masks and personal decoration. In these societies, art and architecture have often been closely connected, for example, storehouses and meetinghouses are often decorated with detailed carvings, and so they are presented together in this discussion.

Until the 16th and 17th centuries when European societies happened upon the scene, Oceanic societies maintained several types of Neolithic technology. The only exception was in the northwest of New Guinea, where the tribes living around Geelvink Bay (Teluk Cenderawasih) traded very small quantities of metal from the Indonesians of the Moluccas (Maluku). The technique of forging was jealously guarded, virtually as a cult secret; some tools were traded but only in quantities too small to have made much impact on usual working conditions.

Throughout the rest of Melanesia and in Polynesia and Micronesia, the basic tool was the stone blade, which was hafted as an adze or an axe, and sometimes interchangeably as both. Tridacna shell was sometimes used as blades in the parts of Oceania where stone was in short supply, including Micronesia and the Solomon Islands. When obsidian was available, it was chipped into blades for use as both weapons and tools. Other working materials included bamboo and bivalve shells, which allow extremely sharp edges. Some fine cutting and engraving was performed with unhafted boar tusks or with hafted shark and rodent teeth. Animal bones served as gouges, awls, and needles. All these instruments were used in working wood, which with very rare exceptions was the main medium used throughout Oceania.

Clay was also used, in the main for sculptures, for some of the smaller musical instruments (whistles), and for pottery in Melanesia and New Guinea. The making of clay vessels was nearly exclusively women’s work, except in a few small areas in New Guinea and the northern Solomons. A typical method involved spiral coiling of rolls of clay. The decorating of the pot was the work of men.

Some working of shell and turtle shell was done with simple drilling and abrading tools. The carving of stone, although obviously providing far more arduous and time-consuming problems than wood, was undertaken remarkably often and occurred throughout the Pacific Islands; hammering, pecking, and polishing were the main methods. Even such a hard a material as jade was mastered by sanding with abrasives.

Paint and painting were thought to animate sculpture, sometimes literally, in religiosymbolic terms, as paint was considered to have magical, vivifying powers. Paints were generally ochres, with some vegetable-derived pigments. Water was the typical medium, occasionally supplemented with sap. Brushes were created from the fibrous ends of chewed or frayed sticks, small feather bundles, pieces of wood, and sometimes the most basic applicator of all, the finger. Apart from sculpture, the surfaces used for painting were rock faces, bark, and tapa (cloth made from pounded bark). Rock painting was most common in Australia, where panels of bark were also used. In Melanesia, paintings were made mainly on sago-palm spathes and sheets of tapa cloth. In Polynesia the women manufactured large amounts of tapa, which were then decorated with traditional designs using vegetable dyes. Some of the techniques they used included painting, stenciling with leaf templates, rubbing over relief-design tables, stamping, and printing with carved bamboo rollers.

The only areas where weaving was practiced were the Caroline Islands, the Polynesian outliers east of the Solomon Islands, a small number of the Santa Cruz Islands, parts of Vanuatu, the Saint Matthias Group (northwest of New Ireland), and several places on the northern coast of Irian Jaya. Spinning was unknown; instead of yarn or thread, strips of banana fibre were used on a simple backstrap loom. Weaving was a woman’s craft in the Caroline and Saint Matthias islands but was practiced by men elsewhere. A form of “finger weaving,” as in net making, was used by Maori women in creating textiles from flax fibres.

The architecture of the Pacific Islands was varied and occasionally large in scale. Buildings reflected the structure and preoccupations of the societies that constructed them, with considerable symbolic detail. Technically, most structures in Oceania were no more than simple assemblages of poles held together with cane lashings; only in the Caroline Islands were complex methods of joining and pegging known.

Oceanic artists’ quest for media was consummately opportunistic; they regarded almost anything from the lavish natural world that surrounded them as potentially usable. The sea yielded shells of all kinds, particularly conus, cowrie, and nassa shells. Birds gave down, beaks, and plumes (those of the birds of paradise were particularly prized); animals provided teeth, tusks, and skins; insects supplied their brilliant wing cases. The vegetable kingdom was drawn upon for flowers, leaves, and fibres. The assembly of such materials into single objects was uncommon in Polynesia and Micronesia, but the practice was typical of Australian and Melanesian styles, and contributed brilliantly to their more spectacular effects. The most basic medium of all was the human body, which received both removable and permanent decorations, including scarification, enhanced by treatment to raise keloid welts in New Guinea, and tattooing with needles and pigments elsewhere.

How to get the most from your Grid-Connected Solar Power System

Posted on 27th December 2010 by squadron in Uncategorized

Ok, so you’ve just had your new grid-connected solar panels connected by your friendly accredited solar power installer.

Now, think back to the first meeting you had with the sales consultant by the kitchen table. Do you recall discussing your prior energy use in the home, and what habits you ought to alter if you decided to get solar? If you answered yes, then you probably organised your solar quote through mysolarprice.com.au, as we only deal with solar companies that we know will provide information to the consumer about their typical power use and give them a better understanding of what power output the system is capable of. Some ‘fly-by-night’ solar panel companies who have just arrived on the scene have misled the public in the performance capacity of their grid connected systems. This has led to some mistrust and confusion in the Solar arena. Mysolarprice.com.au knows of these companies, and will not deal with those solar installers found to be giving misleading information or involved in any dishonest sales tactics.

Have you forgotten the power saving tips the solar consultant gave you? If so, don’t worry, as we have the TOP 15 tips for reducing your power consumption to get the most out of your tariff feed, whether that be Net Tariff feed or Gross Tariff feed. Some businesses with larger systems from 2kw (2 kilowatts) or more may not have to change their behaviour at all and will still be in positive territory, that is, getting a surplus or credit for their power. This depends on the home, roof type, shade, number of people in the home, appliance usage, and most importantly the behaviour in the home or in other words how they interact with their home. Some families work during the day and turn their standby power off, whilst doing their washing and household chores at night time. Whereas other people have an air-conditioned home office which uses a massive amount of power during the day and which does little at night. How does this make a difference you may ask? If you are in a state like Queensland that has a “Net Tariff Feed” this is extremely important. This basically means you get the balance of the power you send to the grid from the amount of power youhave used during the day but not at night, because solar panels do not generate power at night time. Therefore, if you are using a great deal of power during daytime when your solar power system is working the hardest, you are competing or cancelling it out with the amount of power you are feeding back to the grid, or “Net” Feed. If however, you are away during the day and turn off all your appliances at the wall to eliminate inactive and active standby but only leave the essential items on like the fridge, you will be streets ahead of the rest and get more of a “net” balance which means one thing: more $$$$$$ in your pocket!

These top 15 energy saving tips range from modifying the building fabric of the home, to being more energy efficient, to minor behavioural modifications like turning off the lights when you leave the room. This list will be in the order of the simplest minor behaviour modifications to bigger structural changes to the building material.

TOP 15 POWER-SAVING IDEAS

1.Turn the lights off when you leave a room. This is especially important if you have energy-guzzling old-fashioned incandescent lights or worse, halogen lights. I have seen people leave on 4 x tastic 500w heat lamps on in the bathroom all day. That’s an incredible 2KW or 2000 watts of power being consumed for no reason.

2.Allow natural light into the rooms. This will reduce the requirements for lights during the day.

3.Replace all incandescent light bulbs and halogens with CFL’s (Compact Fluorescent Lamps) or LED’s. They use only approx. a quarter or less power than the standard 75watt incandescent or 60watt halogen, and can last far longer than the standard incandescents or halogens.

4.Use Sensor CFL spotlights for outdoors, instead of the old energy-inefficient spotlights of yesterday.

5.Turn off all standby power. This is probably the best tip I can give you for reducing your daily electricity consumption. A typical house generally operates at around 10-15% standby power, so if you have a quarterly bill of $400 that means $40-$60 of that account is standby power -which does nothing! It may not seem like much but that’s around $120-$240 a year just for not turning appliances off at the wall. An easy way to monitor your standby is to install a proper standby power board.

6.Choose energy-efficient appliances. This doesn’t necessarily mean throwing out your 5-year-old fridge because it only has 2 stars, and spending $2,500 on one that is 4 star. It means if you are presented with an option of buying a new appliance, then make sure it has the highest star rating available. So if you have the money and the choice is over a 2 star 50 inch plasma TV or a 5 star 50 inch Led TV you should get the LED.

7.Turn off any second or third fridges not in use. I have found in energy audits that many people have a spare chest freezer or 20-year-old rusting fridge with split seals in a hot garage. This will account for a large chunk of the electricity bill. Often I’ll open the door and there is nothing even in there, so the fridge is running -and working overtime- for no reason.

8.Turn off your computer screens and speakers when not being used. This is so easy, however most people I come across forget to do this. If you have a Sub-Woofer with a separate power supply be sure to turn that off also when not in use.

9.Draft Sealing in Winter. If you use electric heating in winter, be sure to stop any drafts, otherwise you are definitely wasting money.

10.Use ceiling fans or pedestal fans instead of air-conditioning. Air-conditioning can be one of the most expensive appliances to use in summer. If are going to use air-conditioning in summer, make sure that the room is well-sealed, the windows are covered and you have insulation in the ceiling.

11.Air-Conditioning Tips for Summer.

- Buy the right sized air-conditioner for your room -not house, unless it’s ducted. If buying ducted make sure it can be zoned.
- Buy an energy efficient inverter air-conditioner with a high star rating for both cooling and heating.
- Set the thermostat between 18-21 degrees. Every degree celsius higher that you set the a/c increases your usage by 10%
- Re-circulate cool air from within rather than using hot air from outside. If the compressor is outside make sure its not sitting exposed in the western sun.
- Make sure the windows have both internal and external shading.

12.Air-Conditioning Tips for Winter.

- Set the thermostat to 23-26 degrees
- Wear warmer clothes to insulate your body so you don’t need mechanical heating
- Insulate your house as with Air-Conditioning in Summer Tips.
- Because hot air rises, a ceiling fan can be turned to the lowest setting -in reverse- as this actually pushes the warm air down towards the home’s occupants
- Avoid electric radiator heaters and electric fan heaters as they are massively expensive.
You are better using reverse cycle air conditioning as it’s a lot cheaper (most people don’t know this).

13.Insulation. Reflective foil type insulation is better in sub-tropical climates such as Brisbane has, but thicker, bulky insulation such as wool/fibreglass or polyester is better suited to the more temperate climates such as Toowoomba.

14.Windows. There are a number of things you can do to insulate your windows to stop the heat entering the place during summer, and keep it in in winter. In summer it’s important to keep direct solar radiation off the east and west windows by vertical screening, and keep it off north facing windows with big eaves or horizontal shading. This is so you can let the sun in in winter when it is lower in the sky. These are principles known as solar passive design.

15.Hot Water. If your home has an electric hot water system and you have it on the wrong tariff this can be the greater part of your bill. Generally, your hot water should be on an off-peak tariff depending on your location and retail provider. The hot water bill is normally a quarter of the electricity bill if the system is electric. If it is a newer heat pump it will be much less. The most efficient water heating device is Solar Hot Water, with a natural gas boost.

These are just some of the basic energy-saving tips that I have come across while performing household energy audits which I find most people need help with. If you can reduce the daily consumption it’s going to make it a lot easier to:
1. Keep your bills down, and
2. Make it easier for the Solar Panels to work and provide you with a bonus or credit on your next bill.

One other thing I could also mention is panel care. Your panels should be kept free of dirt and grime, as even a small build-up of dust on the panels can significantly reduce the panel’s performance by up to 30% or more. I will look at the process of solar panel maintenance in my next article.

All About The New Red Laser Application For iPhones

Posted on 23rd December 2010 by squadron in Uncategorized - Tags: , ,

The iPhone features a few applications available for it and more are being produced and applied to the application store every day. Almost anybody can create an application for the iPhone and place it in the app store; all that anyone has to do is show the app to Apple for screening and approval.

One helpful application is be the red laser which comes available with the Apple iPhone. The red laser allows people to scan an item and instantly see the available prices of that specific product online. Along with the online comparison shopping which the barcode scanner provides, the red laser also has several other quite useful features. For instance, you can scan a movie noticed while in a shopping mall and the red laser will find a copy of it online and will also provide for you to have the whole movie sent to your TiVo.

The red laser is also able to add items to your shopping list. For example, whenever somebody is about to discard their razor, they can scan the item and it will be added onto their shopping list reminding them to stock up on it next grocery shopping trip.

One can use the red laser to scan just about anything and find information that is applicable to their interests. You can use it on a book and the red laser can find a copy of it in a nearby library. It is able to do this due to its deep integration with the world’s largest library catalogue -WorldCat. The red laser is also able to look for a copy of a book scanned and find any online retailers which hold it in stock.

Other than finding prices and looking for products, the red laser will also let you to scan food. If anybody is allergic to any ingredient, one can scan a product and then tap on the allergen info. Instead of labouring to scan the long list of ingredients in the packaging, red laser will show you a list of all the ingredients within the product and show you the most common allergens within it. In addition to that, red laser will also help you eat more healthily by revealing the full nutritive contents within the food.

Red Laser comes with several other useful features and you may be surprised at the number of items you can scan and find helpful information on. This is definitely an application worth buying.

Why you should turn to stone cladding when building your dream home

Posted on 16th December 2010 by squadron in Uncategorized - Tags:

If you chat to anyone who’s familiar with stone cladding, they’re most likely to tell you one thing over everything else: it’s the bee’s knees. Really, a bunch of rocks and stone never looked so good. If you’re planning at building your own dream home, you might want to consider including stone cladding in the final design of your house.

Far from looking like your typical bunch of rocks stacked on top of each other, most constructions that use stone cladding look very aesthetically pleasing, not to mention reliable and extremely easy to construct. Examples of stacked stone constructions are far and wide and can be found in a range of places. Take for example a certain country retreat in the Daylesford Hills in Victoria, where they opted to go for it instead of the usual sandstone walling. The architect used Craft Stone European Castle Stone Golden Sand as the alternative.

The result of this was a far more pleasant design and they avoided additional footings, particularly by using timber frame & fibre cement as a substrate. This was done for use in an outdoor portion – a rock wall if you will – so it’s something that will often catch the attention of people passing by .

But of course, usage is in no way limited to the outdoor parts of a house. Indoor use is also permitted, and when it comes to cases like these, its benefits can be experienced in a number of ways of ways, whether it ends up in the kitchen or in the rumpus room.

A stacked stone fireplace is an architectural marvel, where a timber frame clad with fibre cement sheet can be used to make. A 12mm Standard mortar joint can be used to fit the Craft Stone Stacked Ledgestone Merlot for the construction. The best part is the whole thing takes a day to construct which brings to light the amazing cost and labor saving incentives . It’s obvious – less construction time means less construction worker costs, and fewer expenses in general.

With clear benefits like those mentioned above, it’s no wonder the stone cladding method is becoming more and more popular nowadays. Add the fact that resulting designs can compliment just about anything, and suddenly it’s not so hard to see why people say it’s the perfect design feature. Stone cladding is what dream homes are made of!

The Importance of Decorative Night Lights in Interior Design

Posted on 6th December 2010 by squadron in Uncategorized

Lighting is am essential aspect of any room. It takes a lot of effort and research to choose the right night lights, as it can make or break a room. Decorative lights can easily liven up a space, regardless of how boring the furniture is. Lighting plays an essential in setting the ambience in a room. Where you place these lights should also be well researched, as misplaced lighting can ruin the mood in a room.

Interior design has significantly improved throughout the years, as decorative pieces and furniture have come to present a more contemporary look to them. With the evolution of interior design trends came the similar evolution of lighting. Designer night lights have become one of the most important aspects of any interior design project. Choosing designer lights that announce a statement fulfills both the aesthetic and functional sides of the designing process. Whether you want more traditional designs or contemporary ones, there is definitely a lighting piece that will suit your needs and preferences.

The addition a lampshade or two in a bedroom can make an amazing difference. Drop lights are also welcome additions to the living room or the dining room and string lights are now becoming a necessity when decorating. There are so many unique choices for night lights these days that it can be rather overwhelming to make an informed decision. Decorative lights add an interesting touch to the room and depending on the kind of light you decide to use, it can set the overall theme of the room. More contemporary designs include LED colour change lights, large drop lights and metallic lighting fixtures. No matter what your interior design theme is, you can find a lighting fixture that will complement it. This even extends to the gardens and ponds with outdoor lighting.

A lot of the modern lights these days are also more cost-efficient they don’t consume too much electricity as before. It is beneficial to choose one center light and include several accent lights so that you are able to dim the lighting in the room should you want to. Warm lighting can greatly influence the ambience in the room, as it is a lot more comfortable than white lights.

Chandeliers have also greatly evolved through the years. From elaborate tear drop chandeliers, they now come in a variety of varying designs and colours. Dark wrought iron chandeliers offer more simplistic options for homes, as they are not as extravagant as traditional chandeliers but can be as beautiful in concept and lighting. Decorative night lights are certainly a great investment, as they can improve the aesthetic appeal of any home.

Plastic Packaging Facts

Posted on 4th December 2010 by squadron in Uncategorized - Tags:

Because packaging helps to mediate the immediate environment of a food product, it is useful in creating conditions that increase the storage life of a food. Packaging materials that are normally used for foods may be classified as flexible (paper, thin laminates, and plastic film), semi-rigid (aluminum foil, laminates, paperboard, and thermoformed plastic), and rigid (metal, glass, and thick plastic). Plastic materials are widely used in food packaging because they are relatively inexpensive, lightweight, and easy to contort into desired shapes.

The selective permeability of polymer-based materials to gases, for example carbon dioxide and oxygen, as well as light and moisture, has led to the invention of modified-atmosphere packaging. If the barrier properties are carefully chosen, a packaging material can maintain a modified atmosphere inside the package and thus extend the shelf life of the food product.

Dehydrated foods must be kept apart from moisture during storage. Packaging materials such as polyvinyl chloride, polyvinylidene chloride, and polypropylene offer low moisture permeability. Similarly, packaging materials with low gas permeability are used for fatty foods in order to minimize oxidation. Because fresh fruits and vegetables respire, they use packaging materials, such as polyethylene, that have high permeability to gases.

Smart packages use properties that meet the special needs of certain consumables. For example, packages made with oxygen-absorbing elements remove oxygen from the inside of the package, thus guarding oxygen-sensitive products from oxidation. Temperature-sensitive films exhibit a sudden change in gas permeability when they are exposed to a temperature above or below a set constant. These films change from a crystalline structure to an amorphous structure at a set temperature, causing the gas permeability to change substantially.
