Dry-ice Blasting
Dry-ice blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it. The method is similar to other forms of media blasting such as sand blasting, plastic bead blasting, or sodablasting in that it cleans surfaces using a medium accelerated in a pressurized air stream, but dry-ice blasting uses dry ice as the blasting medium. Dry-ice blasting is nonabrasive, non-conductive, nonflammable, and non-toxic. Dry-ice blasting is an efficient cleaning method. Dry ice is made of reclaimed carbon dioxide that is produced from other industrial processes, and is an approved media by the EPA, FDA and USDA. It also reduces or eliminates employee exposure to the use of chemical cleaning agents. Compared to other media blasting methods, dry-ice blasting does not create secondary waste or chemical residues as dry ice sublimates, or converts back to a gaseous state, w ...

Abrasive Blasting
Sandblasting, sometimes known as abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurised fluid, typically compressed air, or a Centrifugal force, centrifugal wheel is used to propel the blasting material (often called the ''media''). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, using various media; some are highly abrasive, whereas others are milder. The most abrasive are shot blasting (with metal shot (pellet), shot) and sandblasting (with sand). Moderately abrasive variants include glass bead blasting (with glass beads) and plastic media blasting (PMB) with ground-up plastic stock or walnut shells and corncobs. Some of these substances can cause anaphylactic shock to individuals allergic to the media ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baby Food
Baby food is any soft, easily consumed Human food, food other than breastmilk or infant formula that is made specifically for human babies between six months and two years old. The food comes in many varieties and flavors that are purchased ready-made from producers, or it may be table food eaten by the family that has been mashed or otherwise broken down. Readiness and health Readiness As of 2023, the World Health Organization, UNICEF and many national health agencies recommended waiting until six months of age before starting a child on food. Neither too early nor too late. In Italy in 2020, a survey of parents found that more than two-thirds of babies were first fed baby food when they were five or six months old. A survey in Scotland in 2017 indicated that almost no babies were fed baby food before the age of four months, and that about half of them were not given baby food until they were at least six months old. Inappropriately early introduction of baby food (i.e., befo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peanut Butter
Peanut butter is a food Paste (food), paste or Spread (food), spread made from Grinding (abrasive cutting), ground, dry roasting, dry-roasted peanuts. It commonly contains additional ingredients that modify the taste or texture, such as salt, sweeteners, or emulsifiers. Consumed in many countries, it is the most commonly used of the nut butters, a group that also includes cashew butter and almond butter. Peanut butter is a nutrient-rich food containing Reference Daily Intake, high levels of protein, several vitamins, and dietary minerals. It is typically served as a spread on bread, toast, or crackers and used to make sandwiches (notably the peanut butter and jelly sandwich). It is also used in a number of List of breakfast dishes, breakfast dishes and List of desserts, desserts, such as granola, smoothies, crepes, cookies, Chocolate brownie, brownies, or croissants.

Salmonellosis
Salmonellosis is a symptomatic infection caused by bacteria of the ''Salmonella'' type. It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general). These are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. In humans, the most common symptoms are diarrhea, fever, abdominal pain, abdominal cramps, and vomiting. Symptoms typically occur between 12 hours and 36 hours after exposure, and last from two to seven days. Occasionally more significant disease can result in dehydration. The old, young, and others with a immunocompromised, weakened immune system are more likely to develop severe disease. Specific types of ''Salmonella'' can result in typhoid fever or paratyphoid fever. Typhoid fever and paratyphoid fever are specific types of salmonellosis, known collectively as enteric fever, and are, respectively, caused by salmonella typhi and pa ...

Stonehaven
Stonehaven ( ) is a town on the northeast coast of Scotland, south of Aberdeen. It had a population of 11,177 at th2022 Census Stonehaven was formerly the county town of Kincardineshire, succeeding the now abandoned town of Kincardine, Aberdeenshire, Kincardine. It is currently administered as part of Aberdeenshire. The town is known in the local Doric Scots, Doric dialect as ''Steenhive'' () and is nicknamed ''Stoney''. Pre-history and archaeology Stonehaven is the site of prehistoric events evidenced by finds at Fetteresso Castle and Neolithic pottery excavations from the Spurryhillock area. In 2004, archaeological work by CFA Archaeology, in advance of the building of the Aberdeen to Lochside Natural Gas Pipeline, found two short Cist, cists burials containing cremated remains to the southwest of Stonehaven. Radiocarbon dating put the burials in the first half of the 2nd millennium BC, which was the Early Bronze Age in Scotland. The burials contained stone tool artifacts ...

Listeria Monocytogenes
''Listeria monocytogenes'' is the species of pathogenic bacteria that causes the infection listeriosis. It is a facultative anaerobic bacterium, capable of surviving in the presence or absence of oxygen. It can grow and reproduce inside the host's cells and is one of the most virulent foodborne pathogens. Twenty to thirty percent of foodborne listeriosis infections in high-risk individuals may be fatal. In the European Union, listeriosis continues an upward trend that began in 2008, causing 2,161 confirmed cases and 210 reported deaths in 2014, 16% more than in 2013. In the EU, listeriosis mortality rates also are higher than those of other foodborne pathogens. Responsible for an estimated 1,600 illnesses and 260 deaths in the United States annually, listeriosis ranks third in total number of deaths among foodborne bacterial pathogens, with fatality rates exceeding even ''Salmonella'' spp. and ''Clostridium botulinum''. Named for Joseph Lister, ''Listeria monocytogenes'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escherichia Coli
''Escherichia coli'' ( )Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. is a gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus '' Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' strains are part of the normal microbiota of the gut, where they constitute about 0.1%, along with other facultative anaerobes. These bacteria are mostly harmless or even beneficial to humans. For example, some strains of ''E. coli'' benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by harmful pathogenic bacteria. These mutually beneficial relationships between ''E. coli'' and humans are a type of mutualistic biological relationship—where both the humans and the ''E. coli'' are benefitting each other. ''E. coli'' is expelled into the environment within fecal matter. The bacterium grows massi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonella Enterica Subsp
''Salmonella'' is a genus of rod-shaped, (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two known species of ''Salmonella'' are '' Salmonella enterica'' and '' Salmonella bongori''. ''S. enterica'' is the type species and is further divided into six subspecies that include over 2,650 serotypes. ''Salmonella'' was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon. ''Salmonella'' species are non-spore-forming, predominantly motile enterobacteria with cell diameters between about 0.7 and 1.5 μm, lengths from 2 to 5 μm, and peritrichous flagella (all around the cell body, allowing them to move). They are chemotrophs, obtaining their energy from oxidation and reduction reactions, using organic sources. They are also facultative anaerobes, capable of generating adenosine triphosphate with oxygen ("aerobically") when it is available, or using other electron acceptors or fermentation ("anaerobically") w ...

Food Standards Agency
The Food Standards Agency is a non-ministerial government department of the Government of the United Kingdom. It is responsible for protecting public health in relation to food in England, Wales and Northern Ireland. It is led by a board appointed to act in the public interest. Its headquarters are in London, with offices in York, Birmingham, Wales and Northern Ireland. Its counterpart in Scotland is Food Standards Scotland. History The Agency was created based on a report by Professor Philip James, issued after several high-profile outbreaks and deaths from foodborne illness. It was felt that it was inappropriate to have one government department, the Ministry of Agriculture, Fisheries and Food, responsible for both the health of the farming and food processing industries and for food safety. The creation of the Agency was a manifesto commitment of the Labour Party during its 1997 general election campaign; with the party going on to win the election and form a new governm ...

Food Processing
Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing takes many forms, from grinding grain into raw flour, home cooking, and complex industrial methods used in the making of convenience foods. Some food processing methods play important roles in reducing food waste and improving food preservation, thus reducing the total environmental impact of agriculture and improving food security. The Nova classification groups food according to different food processing techniques. Primary food processing is necessary to make most foods edible while secondary food processing turns ingredients into familiar foods, such as bread. Tertiary food processing results in ultra-processed foods and has been widely criticized for promoting overnutrition and obesity, containing too much sugar and salt, too little fiber, and otherwise being unhealthful in respect to dietary needs of humans and farm animals.

Plastic
Plastics are a wide range of synthetic polymers, synthetic or Semisynthesis, semisynthetic materials composed primarily of Polymer, polymers. Their defining characteristic, Plasticity (physics), plasticity, allows them to be Injection moulding, molded, Extrusion, extruded, or Compression molding, pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends ...
