Art in Oceania

By squadron On December 30th, 2010

The visual art and architecture of native Oceania, includes media such as sculpture, pottery, rock art, masks and personal decoration. In these cultures, art and architecture have often been closely connected, e.g. storehouses and meetinghouses are often decorated with elaborate carvings, and so they are presented together here.

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

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

Clay was also employed, in the main for sculptures, for some of the smaller musical instruments (whistles), and for pottery in Melanesia and New Guinea. The creation of clay vessels was nearly exclusively women’s work, apart from in several areas in New Guinea and the northern Solomons. The usual 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 difficult 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 so resistant a material as jade was mastered by sanding with abrasives.

Paint and painting were thought to animate sculpture, often literally, in religiosymbolic terms, as paint was considered to have magical, vivifying powers. Paints were usually ochres, with other vegetable-derived pigments. Water was the usual medium, on occasion 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 worked 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 created great amounts of tapa, which they then decorated with abstract designs using vegetable dyes. 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, some 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 a great deal of symbolic detail. Technically, most buildings 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 ocean provided 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 rare in Polynesia and Micronesia, but the practice was typical of Australian and Melanesian styles, and added brilliantly to their more spectacular effects. The most basic medium of all was the human body, which allowed for 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

By squadron On December 27th, 2010

Ok, so you have just had your new grid-connected solar panels connected by your local accredited solar power installer.

Now, remember the initial meeting you had with the sales consultant around the kitchen table. Do you recall discussing your prior energy use in the home, and what habits you could change if you decided to get solar? If you answered yes, then you probably organised your solar quote through mysolarprice.com.au, as we only engage solar companies that we are certain will provide information to the consumer about their typical power use and give them a great understanding of what power output the system is capable of. Some ‘fly-by-night’ solar panel companies who have only recently arrived on the scene have misled the public regarding 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 these 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 homes 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 their behaviour in the home or in other words how they interact with their home. Some people 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 and use a massive amount of power during the day and do almost nothing 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. A Net tariff feed 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, as solar panels don’d 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 not there 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 can only mean one thing: more $$$$$$ in your pocket!

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

TOP FIFTEEN POWER-REDUCING IDEAS

1.Turn the lights off when you vacate a room. This is very 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.Let in natural light to 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 about a quarter or less power than the standard 75watt incandescent or 60watt halogen, and can last much longer than the standard incandescents or halogens.

4.Use Sensor CFL spotlights outside, instead of the old energy-inefficient spotlights of old.

5.Turn off all standby power. This is probably the best tip I can give you for reducing your daily electricity consumption. A typical dwelling usually operates at around 10-15% standby power, so if you have a quarterly bill of $400 that means $40-$60 of that bill is standby power -which does nothing! It may not seem like much but that’s approx. $120-$240 a year just for not turning appliances off at the wall. A good way to monitor your standby is to purchase 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 being used. I have found in my energy audits that many people have a spare chest freezer or 20-year-old rusting fridge with deteriorated seals in a hot basement. This will account for a great chunk of your electricity bill. Often I’ve opened the door and there’s 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 are using electric heating in winter, then be sure to cover any drafts, otherwise you are simply wasting money.

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

11.Air-Conditioning Tips for Summer.

- Buy the optimum sized air-con 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 its usage by 10%
- Re-circulate cool air from the inside instead of drawing hot air from outside. If the compressor is outside make sure its not sitting exposed in the western sun.
- Ensure the windows have both internal and external shading.

12.Air-Conditioning Tips for Winter.

- Set the thermostat to 23-26 degrees
- Wear warm clothes to insulate your body so you need less mechanical heating
- Insulate your space 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 house’s occupants
- Avoid electric radiator heaters and electric fan heaters as they are massively expensive.
It is better using reverse cycle air conditioning as it’s far cheaper (most people don’t know this).

13.Insulation. Reflective foil type insulation is best in sub-tropical climates such as Brisbane experiences, whereas 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 home during summer, and keep it in during winter. In summer it is important to keep direct sun rays 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 allow the sun in in winter when it is lower in the sky. These are principles known as solar passive design.

15.Hot Water. If you have 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. A 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 a few of the generic 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 your 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 forgot to mention is panel care. Your panels should be kept free of dirt and grime, as even 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

By squadron On December 23rd, 2010

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

One useful application would be the red laser that comes available with the Apple iPhone. The red laser lets consumers to scan a product and instantly have access to the available prices of that specific item 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 dvd noticed while walking around a shopping mall and the red laser will locate a copy of it online and will also allow you to have the whole film sent to your TiVo.

The red laser is also able to add items to your shopping list. For example, when anyone is going to discard their coffee jar, they can scan the item and it will be added on their shopping list so as to remind them to stock up on it next grocery shopping trip.

One can use the red laser to scan almost anything and get information that is applicable to their interests. You can use it on a book and the red laser will be able to find a copy of it in a nearby library. It is able to do this because of its highly developed 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 locate any online retailers that hold it in stock.

Other than discovering prices and locating products, the red laser will also let you to scan food. If anybody is allergic to an ingredient, one can scan a product and then reveal the allergen info. Instead of labouring to go through the entire list of ingredients in the packaging, red laser will show you a list of all the ingredients within the product and present the most common allergens within it. In addition to that, red laser could also help you eat more healthily by showing you the full nutritive contents within the product.

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

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

By squadron On December 16th, 2010

If you chat to anyone who knows about stone cladding, they’re most likely to tell you one thing over anything else: it’s the bee’s knees. Really, a stack of rocks and stone never looked so good. If you’re thinking of 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 collection of rocks stacked on top of each other, most constructions that use stone cladding are very aesthetically pleasing, not to mention reliable and very 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 chose Craft Stone European Castle Stone Golden Sand as the alternative.

What resulted from this was a far more pleasant design and they avoided additional footings, by using timber frame & fibre cement as a substrate. This was used in an outdoor portion – a rock wall if you will – so it’s something that will catch the attention of passersby .

But of course, usage is not limited to the outdoor parts of a house. Indoor use is also a viable option, and when it comes to cases like these, its benefits can be experienced in all manner of ways, whether it ends up in the kitchen or in the sitting room.

A stacked stone fireplace can take advantage of such an architectural marvel, where a timber frame clad with fibre cement sheet can be used to construct a stone gas log fireplace. 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 astounding cost and labor saving incentives that this could potentially bring to the table. Face it – less construction time means less labour costs, and fewer expenses in general.

With clear benefits such as those mentioned above, it’s no wonder that this method is becoming more and more popular nowadays. Add the fact that resulting designs can compliment just about any design, and suddenly it’s not 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

By squadron On December 6th, 2010

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 a crucial role in creating the ambience in a room. Where you place these lights should also be planned carefully, as misplaced lighting can ruin the mood in a room.

Interior design has significantly changed throughout the years, as decorative pieces and furniture have come to present a more modern look to them. With the development of interior design trends came the similar evolution of ambient lighting. Designer night lights are now one of the most important aspects of a interior design project. Choosing decorative lights that create 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 a crucial 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 attractive touch to the room and depending on the kind of light you choose, it can set the overall theme of the room. More contemporary designs include LED colour change lights, large drop lights and metallic lighting fixtures. irregardless of what your interior design theme is, you can find a lighting fixture that will be ideal. 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 ideal to choose one central light and include several accent lights so that you can dim the lighting in the room should you meed to. Warm lighting can greatly influence the ambience in the room, as it is a lot more pleasing to the eye than white lights.

Chandeliers have also greatly evolved through the years. From elaborate tear drop chandeliers, they now come in varying colours and designs. 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 most certainly a wonderful investment, as they can improve the aesthetic value of any home.

Plastic Packaging Facts

By squadron On December 4th, 2010

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 usually used for foods are usually 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 manipulate into desired shapes.

The selective permeability of polymer-based materials to gases, such as carbon dioxide and oxygen, as well as sunlight and moisture, has led to the development of modified-atmosphere packaging. If the barrier properties are carefully selected, a packaging material can continue a modified atmosphere inside the package and thus extend the shelf life of the food product.

Dehydrated foods must be removed from moisture during storage. Packaging materials such as polyvinyl chloride, polyvinylidene chloride, and polypropylene have low moisture permeability. Similarly, packaging materials with low gas permeability are utilized 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 unique requirements of certain consumables. For example, packages created with oxygen-absorbing elements remove oxygen from the inside of the package, thus protecting oxygen-sensitive products from oxidation. Temperature-sensitive films exhibit an immediate change in gas permeability when they are exposed to an environment above or below a set constant. These films morph from a crystalline structure to an amorphous structure at a set temperature, causing the gas permeability to change substantially.
