Broiler chickens


Broiler chickens are growing fast. At this point they're eating 42 pounds of feed a day, plus grass and bugs they find in the pasture. They'll be seven weeks old tomorrow. Many people butcher at seven weeks, but we keep ours nine weeks for a nice big bird that you can get three meals out of. I think tomorrow I'll take a scale to the pasture and weigh a few.



World broiler production to increase 3.5% in 2009.

Highest waterfall


Country: Venezuela


Height: 979 m


Location: Canaima National park


River: Gauja (Rio Gauya), tributary of Rio ChurĂșn. The last in turn is tributary of Rio Caroni.


The name - Gauja - to the river has been given by Latvian Alejandro Laime, who was the first to reach this waterfall by land. The other Gauja river is located in Latvia - in fact it is among the most beautiful rivers of Latvia. Often there is made mistake by telling that this waterfall is on Rio ChurĂșn.


Other information: At the lower part the waterfall is 150 m wide. Europeans discovered the waterfall in 1935. Waterfalls is named after James Angel - American adventurer, who had to make an emergency landing with his plane nearby in 1937.

Caring For Our Country

Caring for our Country is the Government's new natural resource management program. Caring for our Country is designed as an integrated package with one clear goal, a business approach to investment, clearly articulated outcomes and priorities and improved accountability. It commenced on 1 July 2008 and will integrate delivery of the Commonwealth's existing natural resource management programs, the Natural Heritage Trust, the National Action Plan for Salinity and Water Quality, the National Landcare Program, the Environmental Stewardship Program and the Working on Country Indigenous land and environmental program.

What are Whiskers?

Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from surfaces where tin (especially electroplated tin) is used as a final finish. Tin whiskers have been observed to grow to lengths of several millimeters (mm) and in rare instances to lengths up to 10 mm. Numerous electronic system failures have been attributed to short circuits caused by tin whiskers that bridge closely-spaced circuit elements maintained at different electrical potentials.

Tin whiskers are not a new phenomenon. Indeed, the first published reports of tin whiskers date back to the 1940s and 1950s. Tin is only one of several metals that is known to be capable of growing whiskers. Other examples of metals that may form whiskers include Zinc, Cadmium, Indium and Antimony.

People sometimes confuse the term "whiskers" with a more familiar phenomenon known as "dendrites". Therefore, it is important to note here that whiskers and dendrites are two very different phenomena. A "Whisker" generally has the shape of a very thin, single filament or hair-like protrusion that emerges outward (z-axis) from a surface. "Dendrites", on the other hand, form in fern-like or snowflake-like patterns growing along a surface (x-y plane) rather than outward from it. The growth mechanism for dendrites is well-understood and requires some type of moisture capable of dissolving the metal (e.g., tin) into a solution of metal ions which are then redistributed by electromigration in the presence of an electromagnetic field. While the precise mechanism for whisker formation remains unknown, it is known that whisker formation does NOT require either dissolution of the metal NOR the presence of electromagnetic field.
