Victorian Pharmacy
''Victorian Pharmacy'' is a historical documentary TV series in four parts, first shown on BBC Two in July 2010. It was made for the BBC by independent production company Lion Television. The series producer was Cassie Braben and the Executive Producer was David Upshal. It was filmed at Blists Hill Victorian Town in Shropshire. It is a historical documentary that looks at life in the 19th Century and how people attempted to cure common ailments. Since some of the ingredients of Victorian remedies are now either illegal or known to be dangerous, Professor Nick Barber often used his modern pharmaceutical knowledge to produce similar products without those ingredients. The other main presenters were Tom Quick, a PhD student, and Ruth Goodman, a domestic historian who also appeared in ''Tales from the Green Valley'', ''Victorian Farm'' and ''Edwardian Farm''. Episodes Episode 1 First broadcast 15 July 2010 at 21:00. The first episode is set in 1837. It was made clear that the ser ...

Ruth Goodman (historian)
Ruth Ellen Goodman (born 5 October 1963) is a British freelance historian of the early modern period, specialising in offering advice to museums and heritage attractions. She is a specialist in British social history and after presenting the 2005 television series ''Tales from the Green Valley,'' went on to participate in several BBC historic farm series. She occasionally presents features for ''The One Show'', and she co-presented '' Secrets of the Castle'' in 2014, and ''24 Hours in the Past'' (2015). Early life She was born in Cardiff and went to Westbury primary school and Fearnhill School in Letchworth. "School...was rather pedestrian...I became a very poor student, simply going through the motions, and my academic record at both school and university indeed lacks lustre." Career Goodman "couldn't get a job after university", so she trained for a job as railway ticket clerk, for British Rail, working at Chester railway station, got pregnant, and only lasted a year ...

Syrup
In cooking, a syrup (less commonly sirup; from ar, شراب; , beverage, wine and la, sirupus) is a condiment that is a thick, viscous liquid consisting primarily of a solution of sugar in water, containing a large amount of dissolved sugars but showing little tendency to deposit crystals. Its consistency is similar to that of molasses. The viscosity arises from the multiple hydrogen bonds between the dissolved sugar, which has many hydroxyl (OH) groups. Culinary syrup There are a range of syrups used in food production, including: * Agave syrup, made from agave stem * Cane syrup, made from sugar canes * Chocolate syrup * Corn syrup * Glucose syrup * Golden syrup, a by-product of refining crystallized sugar * High fructose corn syrup, widely used in the US * Maple syrup Common syrups A variety of beverages call for sweetening to offset the tartness of some juices used in the drink recipes. Granulated sugar does not dissolve easily in cold drinks or ethyl alcohol. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dental Drill
A dental drill or handpiece is a hand-held, mechanical instrument used to perform a variety of common dental procedures, including removing decay, polishing fillings, performing cosmetic dentistry, and altering prostheses. The handpiece itself consists of internal mechanical components which initiate a rotational force and provide power to the cutting instrument, usually a dental burr. The type of apparatus used clinically will vary depending on the required function dictated by the dental procedure. It is common for a light source and cooling water-spray system to also be incorporated into certain handpieces; this improves visibility, accuracy and overall success of the procedure. The burrs are usually made of tungsten carbide or diamond. High-speed handpiece High-speed handpieces work at cutting speeds over 180,000 rpm. They are technically categorised into ''air turbine'' and ''speed-increasing'' depending on their mechanisms. In a clinical setting, however, air turbine ...

Dentistry
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the teeth, gums, and mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa. Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist. The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC to 5500 BC. Dentistry is thought to have been the first specialization in medicine which have gone on to develop its own accredited degree with its own specializations. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reas ...

Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Gelatin Dessert
Gelatin desserts (also Jelly or Jello) are desserts made with a sweetened and flavoured processed collagen product ( gelatin). This kind of dessert was first recorded as jelly by Hannah Glasse in her 18th-century book '' The Art of Cookery'', appearing in a layer of trifle. Jelly is also featured in the best selling cookbooks of English food writers Eliza Acton and Isabella Beeton in the 19th century. They can be made by combining plain gelatin with other ingredients or by using a premixed blend of gelatin with additives. Fully prepared gelatin desserts are sold in a variety of forms, ranging from large decorative shapes to individual serving cups. Popular brands of premixed gelatin include: Aeroplane Jelly in Australia, Hartley's (formerly Rowntree's) in the United Kingdom, and Jell-O from Kraft Foods and Royal from Jel Sert in North America. In the US and Canada this dessert is known by the genericized trademark "jello". History Before gelatin became widely available as ...

Custard
Custard is a variety of culinary preparations based on sweetened milk, cheese, or cream cooked with egg or egg yolk to thicken it, and sometimes also flour, corn starch, or gelatin. Depending on the recipe, custard may vary in consistency from a thin pouring sauce (''crème anglaise'') to the thick pastry cream (''crème pâtissière'') used to fill éclairs. The most common custards are used in custard desserts or dessert sauces and typically include sugar and vanilla; however, savory custards are also found, e.g., in quiche. Custard is usually cooked in a double boiler (bain-marie), or heated very gently in a saucepan on a stove, though custard can also be steamed, baked in the oven with or without a water bath, or even cooked in a pressure cooker. Custard preparation is a delicate operation, because a temperature increase of 3–6 °C (5–10 °F) leads to overcooking and curdling. Generally, a fully cooked custard should not exceed 80 °C (~175 °F) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireworks
Fireworks are a class of Explosive, low explosive Pyrotechnics, pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious Celebration (party), celebrations. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'. Aerial fireworks may have their own Air propulsion, propulsion (skyrocket) or be shot into the air by a Mortar (weapon), mortar (aerial shell). Most fireworks consist of a paper or Card stock, pasteboard tube or casing filled with the combustion, combustible materia ...

Match
A match is a tool for starting a fire. Typically, matches are made of small wooden sticks or stiff paper. One end is coated with a material that can be ignited by friction generated by striking the match against a suitable surface. Wooden matches are packaged in matchboxes, and paper matches are partially cut into rows and stapled into matchbooks. The coated end of a match, known as the match "head", consists of a bead of active ingredients and binder (material), binder, often colored for easier inspection. There are two main types of matches: safety matches, which can be struck only against a specially prepared surface, and strike-anywhere matches, for which any suitably frictional surface can be used. Because of the substance used to coat each match, this makes them non-biodegradable. Etymology Historically, the term ''match'' referred to lengths of rope, cord (later cambric) impregnated with chemicals, and allowed to burn continuously. These were used to light fires and fir ...

Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arsenic
Arsenic is a chemical element with the symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry. The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices. It is also a component of the III-V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. A few species of bacteria are able to use arsenic compounds as respiratory metabolites. Trace quantities of arsenic are an essential dietary element in rats, ham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poison
Poison is a chemical substance that has a detrimental effect to life. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered a poison may change depending on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms. In biology, a poison is a chemical substance causing death, injury or harm to organisms or their parts. In medicine, poisons are a kind of toxin that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests. In ecological terms, poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food ...
