Samuel Barbour
Samuel Barbour (1860 – 3 June 1938) was an Australian chemist, photographer and X-ray pioneer in the colony of South Australia. In Australia, the medical men of the day took a slow approach in the adoption of the new science that involved X-rays. Many of the early demonstrations were made by investigators outside the medical field. Upon examination of the initial investigators, several key factors were common. The individuals had already either been experimenting along similar lines to Wilhelm Röntgen with Crookes tubes and such, the physicists or scientists, or were actively associated with electrical work, the electricians, which made them particularly receptive to the technical appeal of the new science of X-rays. Records of the events reveal that among the medical men who witnessed the first images produced as radiographs, a rather small number had any great desire to employ X-rays directly in their own medical practice.Trainor, J.P. (1946). Salute to the X-Ray Pioneers of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...

Clerk
A clerk is a white-collar worker who conducts record keeping as well as general office tasks, or a worker who performs similar sales-related tasks in a retail environment. The responsibilities of clerical workers commonly include Records management, record keeping, filing, staffing service counters, screening callers, and other administrative tasks. In City of London Livery company, livery companies, the clerk is the chief executive officer. History and etymology The word ''clerk'' is derived from the Latin ''clericus'' meaning "cleric" or "clergyman", which is the Latinisation of names, latinisation of the Greek language, Greek ''κληρικός'' (''klērikos'') from a word meaning a "lot" (in the sense of drawing lots) and hence an "apportionment" or "area of land".

King William Street, Adelaide
King William Street is the part of a major arterial road that traverses the CBD and centre of Adelaide, continuing as King William Road to the north of North Terrace and south of Greenhill Road; between South Terrace and Greenhill Road it is called Peacock Road. At approximately wide, King William Street is the widest main street of all the Australian State capital cities. Named after King William IV in 1837, it is historically considered one of Adelaide's high streets, for its focal point of businesses, shops and other prominent establishments. The Glenelg tram line runs along the middle of the street through the city centre. History King William Street was named by the Street Naming Committee on 23 May 1837 after King William IV, the then reigning monarch, who died within a month. It is historically considered one of Adelaide's high streets, for its focal point of businesses, shops and other prominent establishments. In August 1977, the first bus lane in Adelaide op ...

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of Chemistry#Subdisciplines, subdisciplines of chemistry. Materials science, Materials scientists and metallurgists sha ...

Emigrated
Emigration is the act of leaving a resident country or place of residence with the intent to settle elsewhere (to permanently leave a country). Conversely, immigration describes the movement of people into one country from another (to permanently move to a country). A migrant ''emigrates'' from their old country, and ''immigrates'' to their new country. Thus, both emigration and immigration describe migration, but from different countries' perspectives. Demographers examine push and pull factors for people to be pushed out of one place and attracted to another. There can be a desire to escape negative circumstances such as shortages of land or jobs, or unfair treatment. People can be pulled to the opportunities available elsewhere. Fleeing from oppressive conditions, being a refugee and seeking asylum to get refugee status in a foreign country, may lead to permanent emigration. Forced displacement refers to groups that are forced to abandon their native country, such as by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servant
A domestic worker is a person who works within a residence and performs a variety of household services for an individual, from providing cleaning and household maintenance, or cooking, laundry and ironing, or care for children and elderly dependents, and other household errands. The term "domestic service" applies to the equivalent occupational category. In traditional English contexts, such a person was said to be "in service". Some domestic workers live within their employer's household. In some cases, the contribution and skill of servants whose work encompassed complex management tasks in large households have been highly valued. However, for the most part, domestic work tends to be demanding and is commonly considered to be undervalued, despite often being necessary. Although legislation protecting domestic workers is in place in many countries, it is often not extensively enforced. In many jurisdictions, domestic work is poorly regulated and domestic workers are subje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nurse
Nursing is a health care profession that "integrates the art and science of caring and focuses on the protection, promotion, and optimization of health and human functioning; prevention of illness and injury; facilitation of healing; and alleviation of suffering through compassionate presence". Nurses practice in many specialties with varying levels of certification and responsibility. Nurses comprise the largest component of most healthcare environments. There are shortages of qualified nurses in many countries. Nurses develop a plan of care, working collaboratively with physicians, therapists, patients, patients' families, and other team members that focuses on treating illness to improve quality of life. In the United Kingdom and the United States, clinical nurse specialists and nurse practitioners diagnose health problems and prescribe medications and other therapies, depending on regulations that vary by state. Nurses may help coordinate care performed by other provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
