In flight the members of the flock will call to one another with a high-pitched ‘cree-cree’ call.īy Scarlet23 at English Wikipedia, CC BY-SA 3.0, īy Jean and Fred from Perth, Australia – Red-tailed Black Cockatoo, CC BY 2.0, A group of red-tailed black cockatoos will spend most of their day feeding before returning to trees along rivers and streams where they will roost for the night.įlocks of red-tailed black cockatoos move around based on food availability throughout the year. They may also be seen in pairs and trios. In northern Australia though some have grown to include as many as 200 birds. These birds form flocks which usually are quite small. Sexual maturity is reached at 4 years old. They remain with their parents after this and may still be fed by them. The chicks will fledge at between 10 and 12 weeks old. When they initially hatch the female does all the feeding but once they are older the male will contribute to feeding the chicks. She is responsible for all the incubation of these eggs.Īt birth the chick has no feathers but soon develops a coat of downy yellow feathers. Into this nest the female will deposit a single white egg. This is lined with wood dust, woodchips and splinters. Nesting occurs in a tree hollow which is usually in a dead or mature eucalypt tree. Some populations feed on the ground while others are extremely picky and only eat the seeds of a few trees.īreeding has been recorded year round depending on the population and their location across the country.Ĭourtship involves the male strutting along a branch towards the female with his tail feathers fanned out and crest ruffled up. Most of their feeding takes place in the trees. Their diet includes seeds, fruits, berries, grasses, bulbs, insects and larva. Red-tailed black cockatoos are omnivores. Their body measures between 50 and 65cm (19.7-25.6in) long. This will be raised as a greeting, in excitement or alarm. On top of the head is a crest of feathers which they can raise. Both the male and female have a dark brown eye. This strong beak allows them to break in to seeds and nuts. Their beak is grey in males and off white in females with a large curve. The females also have yellow spots across the head.įive separate races of the red-tailed black cockatoo are recognized with each having slight physical differences. Females lack the bright red color and instead have pale, yellow, yellow-orange or orange-red depending on the race. Males have a patch of bright red feathers in a panel on their tail from which the name of this species is derived. The red-tailed black cockatoo is a large member of the cockatoo family covered with black feathers across the majority of their body with brownish feathers on the primaries.

This is different from how soap works.USE THEM ANYWHERE: SinkSuds were designed to be taken anywhere and used anywhere they are a travel must have! Wash clothes on-the-go no matter your amenities – sink, bathtub, or washer. While liquid laundry detergent looks and feels like liquid soap, it’s actually a type of chemical compound that suspends dirt molecules from the clothing so they can be washed away by the water. Many people think laundry detergent is actually just a different kind of soap.Ensure the laundry detergent can handle anything you throw at it so your clothes turn out clean and fresh every time. While you’re on the road, you may end up getting dirtier than usual, especially if you’re enjoying the great outdoors. Be sure to check the cleaning power of the laundry detergent travel pack.Go with an unscented laundry detergent if you want to avoid any allergic reactions. This can irritate not only your skin, but also your eyes and your nose. If you have sensitive skin, avoid any laundry detergent travel packs that have a fragrance. The process may be the same for some brands as the regular laundry detergent but may differ slightly for others.
The Primeknit upper follows the shape of the foot well and even the reinforced parts aren't too rigid so they would hold the fabric away from the body, creating an unnecessary hollow area. Your heels feel secure and locked in but not restricted which is probably the best combination of sensations in a running shoe. The first thing I noticed when I slipped my feet in the Adidas 4D Run 1.0 was the padding around the heel and the chunky collar of the shoes. (Image credit: ) Adidas 4D Run 1.0 review: the ergonomics Hoka One One Rocket X review: light delight carbon-assisted long-distance running trainers. I personally like the fit of the Primeknit shoes and the Adidas 4D Run 1.0 is no different, despite it being on the snug side. Truth to be told, it's hard refute such claims but let's just assume that it's true and the 3D printed lattice sole is the cumulation of almost two decades' worth of data.Īt the top of the shoes you'll find the Primeknit upper which is the same technology used in most high-end Adidas running shoes. It is being emphasised everywhere that the shoes were "programmed with 17 years of athlete data" to ensure the Adidas 4D Run 1.0 is provides enough stability, comfort and cushioning to every runner. The “4D” bit in the name refers to the printing process that is enabled by Digital Light Synthesis – the next-generation of 3D-printing – but according to Adidas, it is athlete data that makes 4D truly unique. The showstopper is definitely the 3D printed sole: it is a result of the collaboration between Adidas and Carbon, a California-based firm specialising in 3D printing.Īnd we are not talking about any ol' 3D printing either. (Image credit: ) Adidas 4D Run 1.0 review: the techĭespite being such a innovative shoe, there isn't much information available on what tech is involved in the Adidas 4D Run 1.0. The 8.9 sports the same carousel-style interface that the Fire HD has, but it's faster and smoother and generally very impressive indeed. The underside of the tablet reveals micro HDMI and micro USB ports for charging and for hooking up to HD devices, while Bluetooth connectivity means that you can use compatible gadgets including headphones and keyboards. On the right-hand edge you'll find a headphone socket along with the power button and volume rocker - both of which sit entirely flat against the tablet, resulting in a sleek finish but making them quite tricky to find without looking. The back of the tablet sports a relatively grippy brushed rubber finish, but the liklihood is that that you'll be rocking a case to protect your tablet from the cruel, harsh environment that is the inside of your bag. However, it's still a fair bit heavier than it the 7-inch version - we found that it wasn't that comfortable to hold as an ereader for too long. The new Kindle weighs in at 567g and measures 8.8mm thick, making a very compact package, making it lighter and more svelte than the iPad 4. Amazon Kindle Fire HD 8.9: Size and build While the original model went head to head with 7-inch tablets like the iPad Mini, Google Nexus 7 and the Nook HD, the larger version has more in common with the 9-inch Nook HD+, the 9.7-inch iPad 4 and the Google Nexus 10. The 8.9-inch version was released in the US last year, but we've had to wait until 2013 for it to make it across the pond to the UK. The Amazon Kindle Fire HD 8.9" is the big brother to the Amazon Kindle Fire HD which eventually hit UK shores in 2012. Please contact the IT Help Desk at for information on data encryption.

PostgreSQL TO_NUMBER format as percentage.PostgreSQL TO_NUMBER format decimal places.PostgreSQL TO_NUMBER format with commas.PostgreSQL TO_NUMBER format thousand separator.PostgreSQL TO_NUMBER format signed integers.PostgreSQL TO_NUMBER format with leading zeros.In this tutorial, you have learned about the PostgreSQL NUMERIC data types and how to use NUMERIC column to store numbers. ORDER BY price DESC Code language: SQL (Structured Query Language) ( sql )Īs you can see from the output, the NaN is greater than 500.21 The following query sorts the products based on prices: SELECT * FROM products This implementation allows PostgreSQL to sort NUMERIC values and use them in tree-based indexes. However, two NaN values are equal and NaN is greater than other numbers. It means that the expression NaN = NaN returns false. Typically, the NaN is not equal to any number including itself. The following query returns the data of the products table: SELECT * FROM products Notice that you must use single quotes to wrap the NaN as shown in the UPDATE statement above. SET price = 'NaN' WHERE id = 1 Code language: SQL (Structured Query Language) ( sql ) The following example updates the price of the product id 1 to NaN : UPDATE products In addition to holding numeric values, the NUMERIC type can also hold a special value called NaN which stands for not-a-number. Code language: Shell Session ( shell ) PostgreSQL NUMERIC type and NaN PostgreSQL issued the following error: ERROR: numeric field overflowĭETAIL: A field with precision 5, scale 2 must round to an absolute value less than 10^3. VALUES( 'Phone', 123456.21) Code language: SQL (Structured Query Language) ( sql ) In case you store a value whose precision exceeds the declared precision, PostgreSQL will raise an error as shown in the following example: INSERT INTO products ( name, price) The following query returns all rows of the products table: SELECT * FROM products Code language: SQL (Structured Query Language) ( sql ) ( 'Tablet', 500.214) Code language: SQL (Structured Query Language) ( sql )īecause the scale of the price column is 2, PostgreSQL rounds the value 500.215 up to 500.22 and rounds the value 500.214 down to 500.21 : Second, insert some products with prices whose scales exceed the scale declared in the price column: INSERT INTO products ( name, price) ) Code language: SQL (Structured Query Language) ( sql ) If you store a value with a scale greater than the declared scale of the NUMERIC column, PostgreSQL will round the value to a specified number of fractional digits.įirst, create a new table named products for the demonstration: DROP TABLE IF EXISTS products Let’s take some example of using the PostgreSQL NUMERIC type. If precision is not required, you should not use the NUMERIC type because calculations on NUMERIC values are typically slower than integers, floats, and double precisions. In PostgreSQL, the NUMERIC and DECIMAL types are equivalent and both of them are also a part of SQL standard. NUMERIC Code language: SQL (Structured Query Language) ( sql ) If you omit both precision and scale, you can store any precision and scale up to the limit of the precision and scale mentioned above. The following shows the syntax of NUMERIC type with scale zero: NUMERIC(precision) Code language: SQL (Structured Query Language) ( sql ) The scale of the NUMERIC type can be zero or positive. The NUMERIC type can hold a value up to 131,072 digits before the decimal point 16,383 digits after the decimal point. For example, the number 1234.567 has the precision 7 and scale 3. In this syntax, the precision is the total number of digits and the scale is the number of digits in the fraction part. The following illustrate the syntax of the NUMERIC type: NUMERIC(precision, scale) Code language: SQL (Structured Query Language) ( sql ) Typically, you use the NUMERIC type for numbers that require exactness such as monetary amounts or quantities. The NUMERIC type can store numbers with a lot of digits.

Particularly finding some standards to use. There were certain aspects of this lesson plan in which my past experience didn’t directly apply. Relying on the way of thinking I practiced during this time of my life was quite helpful in this activity. Namely, there was a workshop I took in my undergraduate studies in which we practiced creative music composition and improvisation techniques that came in handy. I have a fair amount of musical skills amassed over the years that made this assignment fairly straightforward. In order to do this, I had to constantly ask myself some of the following questions, “What musical experiences does this problem remind me of? How can I relate the principles of this HOM to musical situations that I’m familiar with? What parts of the problem of applying HOM to music could I use more clarity on?” That’s because it took a fair bit of piecing together old skills to figure out exactly how the more general metacognitive techniques of Interdependent Thinking specifically fit into music. This was based on some musings from an earlier assignment (see: ).Īlthough the content of the proposed lesson plan was centered on the “Thinking Interdependently” HOM, I found that I actually had to use more of the “Applying Past Knowledge” HOM in order to create it. I created a proposal for a music lesson plan which centered on the Habit of Mind “Thinking Interdependently” See the proposal here. I guess in the end, like anything, what does any skill mean without its opposite? What is repetition without variance? What is control without chaos? What is logic without irrationality? What is orderly without the disorderly? What is soft without loud, or high without low, wide without narrow, or sparse without dense? Edit Reply Reply with AI In these cases, a controlled, broad kind of inaccuracy is the name of the game! Such instances might include if you’re a composer and you need to paraphrase a musical idea, if you’re a soloist and you want to avoid a “rigid” type of sound, or if you’re an improvisor and you are striving for wide variation from a common theme. In a musical situation, for example, it can be often be entirely appropriate to employ a “loose” type of mindset. In contrast to the importance of accuracy and precision, I do also think that consciously employing the opposite approach from time to time can be a necessary, rewarding and fun endeavor. It was an example of how sometimes, the nitty-gritty details can get you - so watch out! Although nothing bad happened, I did end up having to rewrite a comment in the more specific format that was specified. There were some specific guidelines for discussion that I was required to follow, but I neglected to carefully study to the specific requirements. I did this, for the most part, but my own lack of attention to detail got me caught up in the final stages, causing me to have to go back over my own work. I was supposed to write an educational proposal for a lesson plan, publish it on YouthVoices and then comment on several of my peers’ works. This week I had an assignment which challenged me in this particular Habit of Mind. |
