01 Sep 10 The History Behind Bronze Sculptures

Bronze sculpture is the most common form of cast metal sculptures as a result of a characteristic trait which is as unusual as it’s desirable. Commonly used bronze alloys will expand a little just before being set so that even the finest details of a mold are filled.

Bronze sculptures are also strong while ductile, or lacking in brittleness, allowing figures to be depicted in actions such as leaps and flights. Supports for bronze statues require smaller cross-sections due to such qualities, as can be seen in equestrian statues where only two hooves are on the base.

Today’s examples are generally created of ninety percent copper and ten percent tin, while in antiquity bronze works were occasionally made with other elements such as phosphorus, manganese, aluminum, or silicon. Interestingly, far more stone and ceramic works have come down to us through the ages than those made of bronze, as the metal was quite precious and often melted down to produce new sculptures or weapons and armor in times of war.

Thus, really few big examples in bronze are available from ancient times, and of these most aren’t in good condition. Indeed, most works exhibited in museums, while still full of the evidence of wear and tear, have been painstakingly restored to a quality suitable for display.

Working successfully with bronze typically requires a high level of skill, and a number of distinct casting processes may need to be employed, such as lost-wax casting and the related modern-day technique of investment casting. Other techniques include sand casting and centrifugal casting.

After final polishing, corrosive materials might be applied to bronze works in order to form a patina or film produced by oxidation or some other chemical method and establish some control over the color and finish. For example, reactive chemicals may be applied to produce a novel marble-like appearance.

Camping supplies are a necessity even when simply hiking. This is because there’s always the possibility of mishap which will cause you to stay the night in the forest (mountain or desert or wherever else you’re trekking through).

Never underestimate the power of Mother Nature; the weather conditions can change in a sudden flash in many places upon the earth.

Food and water is next, and it’s a good idea to bring at least one day’s worth, though three days’ is the standard recommended minimum.

Emergency supplies such as first-aid kits and flare signals should also be packed. Needless to say, much depends on your choice of venue, the time of year, and your own familiarity with the location as well as your general expertise in the field, but having the right equipment around should disaster or, even, just a relatively minor setback, strike won’t cost you too much in terms of weight.

Essential camping gear ought to be no more than thirty pounds or so, very easily portable and convenient. Do not skimp on common sense! Most serious hikers, campers, and outdoors types know that the possibility of danger is often present, however minimized. If you are just a casual camper or hiker, then you truly need to do things by the book and think a few steps ahead!

30 Aug 10 Why Medical Office Supplies Are So Important

Stocking and supplying medical office supplies has usually been one of the duties of a hospital dispensary, which is mainly dedicated to dispensing medication according to doctors’ prescriptions. These days, the term “dispensary” refers to a handful of different institutions around the world – or, even, within the country.

For instance, in California a dispensary can be a specially designated store licensed to sell not medical office supplies but medicinal marijuana (which is also the case in the Canadian province of British Columbia), while in the states of Idaho and South Carolina a dispensary used to refer to the governmental agency that served as the only legal source of alcohol.

Also no source of medical office supplies is the Kenyan dispensary, a small outpatient health facility usually managed by a registered nurse. These nurses report to clinical officers at a health centre, which is also where patients are referred to for treatment in cases much more complicated than a common ailment like cold or malaria. Modeled on the British system, this sort of health care dispensary is no simple storehouse of supplies but what Americans would call a community clinic.

This kind of medical clinic or dispensary got its start in London, England back in the 1700s, and is credited with aquainting doctors with the issues of the poor mainly because unlike the case with hospitals or a private practice, this dispensary service actually brought doctors into their patients’ homes. Their social consciences shocked, thus were the first dispensaries set up – free healthcare for the poor.

Indeed, young aspiring doctors of the day had been very eager to serve as honorary physicians to the dispensaries, though such an appointment was generally voluntary (with no more than a small honorarium at best) and not as prestigious as a hospital posting. It was nothing short of a health care revolution: for the first time since the Hippocratic Oath, altruistic motivations had been the norm.
