MINERALS

SO while getting deep into and around minerals and there shapes, I got to learn about an very interesting thing called the Knoop test.
Knoop hardness test

The Knoop hardness test is a microhardness test - a test for mechanical hardness used particularly for very brittle materials or thin sheets, where only a small indentation may be made for testing purposes. A pyramidal diamond point is pressed into the polished surface of the test material with a known force, for a specified dwell time, and the resulting indentation is measured using a microscope. The geometry of this indenter is an extended pyramid with the length to width ratio being 7:1 and respective face angles are 172 degrees for the long edge and 130 degrees for the short edge. The depth of the indentation can be approximated as 1/30 of the long dimension.[1] The Knoop hardness HK or KHN is then given by the formula:

where:
L = length of indentation along its long axis
Cp = correction factor related to the shape of the indenter, ideally 0.070279
P = load
HK values are typically in the range from 100 to 1000, when specified in the conventional units of gf·mm−2. The SI unit, pascals, are sometimes used instead: 1 kgf·mm−2 = 9.80665 MPa.
The test was developed by Frederick Knoop[2] and colleagues at the National Bureau of Standards (now NIST) of the USA in 1939, and is defined by the ASTM D1474 standard.
The advantages of the test are that only a very small sample of material is required, and that it is valid for a wide range of test forces. The main disadvantages are the difficulty of using a microscope to measure the indentation (with an accuracy of 0.5 micrometre), and the time needed to prepare the sample and apply the indenter. - #Glad we got this bit out of the way… hahaha!

Digital bird book found: OWLS. Family Alucondidae

OWLS. Family Alucondidae.

I’ve been influenced by these birds lately. Not sure if it is the colour palette they so contently wear or the nature of their presence. While taking a closer look at these beautiful creatures i found this book about birds and there is quite a nice section on OWLS. Family Alucondidae.

THE ICELANDSCAPE

The landscape is very important for Icelanders. Almost 30 percent of Icelanders rate it more important than the flag or even Icelandic language. And maybe that’s why the landscape almost hasn’t changed since 874 A. D. when Ingólfur Arnarson settled in the area of Reykjavik.

100 ABANDONED HOUSES

The abandoned houses project began innocently enough roughly ten years ago. I actually began photographing abandonment in Detroit in the mid 90’s as a creative outlet, and as a way of satisfying my curiosity with the state of my home town. I had always found it to be amazing, depressing, and perplexing that a once great city could find itself in such great distress, all the while surrounded by such affluence.

Brush Park, on the outskirts of Detroit’s entertainment district was always an area of interest to me. For as long as I can remember the area, housing large houses and mansions, sat largely abandoned just a stones throw away from the Fox Theater, and not far from Wayne State University, the Masonic Theater, and even the central business district. How could an area that was obviously once a wealthy enclave in the city become an example of the downfall of American cities?

For years the area had signs advertising the redevelopment that was about to take place. It finally began to happen, with the construction of the new ballpark for the Tigers, and Ford Field for the Lions. New condos, and town homes began to appear amidst the rubble of burned out mansions turned apartments. Some of the houses were so large they became “loft condos”. As the entertainment district flourished, and Brush Park began to transform into something new, I realized the other approximately 135 square miles of Detroit was largely ignored. The excitement about Detroit’s “rebirth” took center stage, while much of the rest of the city was becoming largely abandoned. Even Brush Park itself was still largely abandoned, but with the remaining tenants of Brush Park buildings being pushed out, and many of the old houses torn down, I moved on to other areas, where Detroiters were attempting to make a life among abandoned and burned out houses. Often times, the neighborhoods were almost completely abandoned. In these neighborhoods I encountered concerned citizens, packs of wild dogs, 20 foot high piles of toilets, and houses with the facades torn off, filled with garbage.

As the number of images grew, and a documentary style emerged, I switched from mostly black and white, to color, and decided to name the series 100 Abandoned Houses. 100 seemed like a lot, although the number of abandoned houses in Detroit is more like 12,000. Encompassing an area of over 138 square miles, Detroit has enough room to hold the land mass of San Francisco, Boston, and Manhattan Island, yet the population has fallen from close to 2 million citizens, to most likely less than 800,000. With such a dramatic decline, the abandoned house problem is not likely to go away any time soon.

GREENHOUSE BY JOOST

The Greenhouse by Joost is an Australian first in sustainable design and innovation. Built entirely from recycled and recyclable materials.

While the Greenhouse grew from an empty site in Federation Square, Annemarie Kiely, Earl Carter and Studio Pip and Co. nailed down Joost, made sense of the Greenhouse project and all the ideas flying in his world.
As the structure had not been built before, the best one could describe and illustrate the project is by illustrating the materials, methods and contributors to the project – the recycling guy, the compost man, the builders, the raw ingredients, the food, straw bails, steel, the furniture, the fittings…

The publication is designed to have many uses. Of the six four page sections, the outer four page sections are two sided posters, the two inner sections remaining house all the written information. This outcome allows Joost, or the user, to use the posters for publicity and promotional purposes, while leaving the written information intact.
The publication was pulled together (the concept, layout design, additional writing, and proofing) in a little over two weeks, the photography and writing component over eight weeks. The straw bail on the front cover was a last minute inspiration. The cover offers the opportunity to set the tone of the publication – the straw bail was the perfect image, as it is a key building material that maintains the temperature within the Greenhouse itself. It is also an unconventional, simple and evolutionary building product.

Joost was attracted to using newsprint technology as a printed product – it a process that can come together rapidly, it is inexpensive and the end product can be recycled, or composted easily. Newsprinters based in Shepparton was then introduced and brought their knowledge and experience to the piece. Newsprinters specified a unique news printer paper made from 77% recycled paper, – Nornews 45gsm, by Norske Skog manufactured in Albury, NSW. All that was left was to upload artwork, a high resolution PDF document, to Newsprinters internet server, then overnight proofing, plates, printing and delivery back to Melbourne within 18 hours, ready for the when the doors opened to the public.
