Locard's Exchange Principle
In forensic science, Locard's principle holds that the perpetrator of a crime will bring something into the crime scene and leave with something from it, and that both can be used as forensic evidence. Dr. Edmond Locard (1877–1966) was a pioneer in forensic science who became known as the Sherlock Holmes of Lyon, France. He formulated the basic principle of forensic science as: "Every contact leaves a trace". It is generally understood as "with contact between two items, there will be an exchange." Paul L. Kirk expressed the principle as follows: Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as a silent witness against him. Not only his fingerprints or his footprints, but his hair, the fibres from his clothes, the glass he breaks, the tool mark he leaves, the paint he scratches, the blood or semen he deposits or collects. All of these and more, bear mute witness against him. This is evidence that does not forget. It is not confused b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forensic Science
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.

Sandals
Sandals are an open type of footwear, consisting of a sole held to the wearer's foot by straps going over the instep and around the ankle. Sandals can also have a heel. While the distinction between sandals and other types of footwear can sometimes be blurry (as in the case of '' huaraches''—the woven leather footwear seen in Mexico, and peep-toe pumps), the common understanding is that a sandal leaves all or most of the foot exposed. People may choose to wear sandals for several reasons, among them comfort in warm weather, economy (sandals tend to require less material than shoes and are usually easier to construct), and as a fashion choice. Usually, people wear sandals in warmer climates or during warmer parts of the year in order to keep their feet cool and dry. The risk of developing athlete's foot is lower than with enclosed shoes, and the wearing of sandals may be part of the treatment regimen for such an infection. History The oldest known sandals (and the olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waste Container
A waste container, also known as a dustbin, garbage can, and trash can is a type of container that is usually made out of metal or plastic. The words "rubbish", "basket" and "bin" are more common in British English usage; "trash" and "can" are more common in American English usage. "Garbage" may refer to food waste specifically (when distinguished from "trash") or to municipal solid waste in general. Designs A pedal bin is a container with a lid operated by a foot pedal. Lillian Moller Gilbreth, an industrial engineer and efficiency expert, invented the pedal bin in the 1920s for the disposal of kitchen waste. The foot pedal enables the user to open the lid without touching it with their hands. In the 2010s, some bins have begun to include automated mechanisms such as a lid with infrared detection on the top of the can powered by batteries to open it rather than a foot pedal, freeing the user from touching the bin in any way. This helps prevent the bin lids becoming clogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lint (material)
Lint is the common name for visible accumulations of textile fibers and other materials, usually found on and around clothing. Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together. During the course of normal wear, these fibers may either detach or be jostled out of the weave of which they are part. This is the reason why heavily-used articles such as shirts and towels become thin over time and why such particles accumulate in the lint screen of a clothes dryer. Because of their high surface area to weight ratio, static cling causes fibers that have detached from an article of clothing to continue to stick to one another and to that article or other surfaces with which they come in contact. Other small fibers or particles also accumulate with these clothing fibers, including human and animal hair and skin cells, plant fibers, and pollen, dust, and microorganisms. The etymology of the moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cookies
A cookie is a baked or cooked snack or dessert that is typically small, flat and sweet. It usually contains flour, sugar, egg, and some type of oil, fat, or butter. It may include other ingredients such as raisins, oats, chocolate chips, nuts, etc. Most English-speaking countries call crunchy cookies biscuits, except for the United States and Canada, where biscuit refers to a type of quick bread. Chewier biscuits are sometimes called ''cookies'' even in the United Kingdom. Some cookies may also be named by their shape, such as date squares or bars. Biscuit or cookie variants include sandwich biscuits, such as custard creams, Jammie Dodgers, Bourbons and Oreos, with marshmallow or jam filling and sometimes dipped in chocolate or another sweet coating. Cookies are often served with beverages such as milk, coffee or tea and sometimes "dunked", an approach which releases more flavour from confections by dissolving the sugars, while also softening their texture.

Prosecution
A prosecutor is a legal representative of the prosecution in states with either the common law adversarial system or the civil law inquisitorial system. The prosecution is the legal party responsible for presenting the case in a criminal trial against an individual accused of breaking the law. Typically, the prosecutor represents the state or the government in the case brought against the accused person. Prosecutor as a legal professional Prosecutors are typically lawyers who possess a law degree, and are recognised as suitable legal professionals by the court in which they are acting. This may mean they have been admitted to the bar, or obtained a comparable qualification where available - such as solicitor advocates in England and Wales. They become involved in a criminal case once a suspect has been identified and charges need to be filed. They are employed by an office of the government, with safeguards in place to ensure such an office can successfully pursue the prosec ...

Pajamas
Pajamas (American English, US) or pyjamas (English in the Commonwealth of Nations, Commonwealth) (), sometimes colloquially shortened to PJs, jammies, jam-jams, or in South Asia night suits, are several related types of clothing worn as nightwear or while lounging or performing remote work from home. Pajamas are soft and loose garments derived from the Indian subcontinent, Indian and Persian culture, Persian bottom-wear, the ''pyjamas''. They originated in the Indian subcontinent and were adopted in the Western world as nightwear. Etymology According to the ''Oxford English Dictionary'', the word pajama is a borrowing via Hindi from Persian language, Persian. Its etymology is: Hindi pāy-jāma, pā-jāma and its etymon Persian pāy-jāma, pā-jāma, singular noun < Persian pāy, pā foot, leg + jāma clothing, garment (see jama n.1) + English -s , plural ending, after drawers.

Wrestle
Wrestling is a series of combat sports involving grappling-type techniques such as clinch fighting, throws and takedowns, joint locks, pins and other grappling holds. Wrestling techniques have been incorporated into martial arts, combat sports and military systems. The sport can either be genuinely competitive or sportive entertainment (see professional wrestling). Wrestling comes in different forms such as freestyle, Greco-Roman, judo, sambo, folkstyle, catch, submission, sumo, pehlwani, shuai jiao and others. A wrestling bout is a physical competition, between two (sometimes more) competitors or sparring partners, who attempt to gain and maintain a superior position. There are a wide range of styles with varying rules, with both traditional historic and modern styles. The term ''wrestling'' is attested in late Old English, as ''wræstlunge'' (glossing ''palestram''). History Wrestling represents one of the oldest forms of combat. The origins of wrestling g ...

Ritual
A ritual is a sequence of activities involving gestures, words, actions, or objects, performed according to a set sequence. Rituals may be prescribed by the traditions of a community, including a religious community. Rituals are characterized, but not defined, by formalism, traditionalism, invariance, rule-governance, sacral symbolism, and performance. Rituals are a feature of all known human societies. They include not only the worship rites and sacraments of organized religions and cults, but also rites of passage, atonement and ritual purification, purification rites, oaths of allegiance, dedication ceremonies, coronations and presidential inaugurations, marriages, funerals and more. Even common actions like handshake, hand-shaking and saying "hello" may be termed as ''rituals''. The field of ritual studies has seen a number of conflicting definitions of the term. One given by Kyriakidis is that a ritual is an outsider's or "Emic and etic, etic" category for a set activity (o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedroom
A bedroom or bedchamber is a room situated within a residential or accommodation unit characterised by its usage for sleeping and sexual activity. A typical western bedroom contains as bedroom furniture one or two beds (ranging from a crib for an infant, a single or twin bed for a toddler, child, teenager, or single adult to bigger sizes like a full, double, queen, king or California king astern or waterbed size for a couple, a clothes closet, and bedside table and dressing table, both of which usually contain drawers. Except in bungalows, ranch style homes, ground floor apartments, or one-storey motels, bedrooms are usually on one of the floors of a dwelling that is above ground level. History In larger Victorian houses it was common to have accessible from the bedroom a boudoir for the lady of the house and a dressing room for the gentleman. Attic bedrooms exist in some houses; since they are only separated from the outside air by the roof they are typically cold in win ...

Kidnapping
In criminal law, kidnapping is the unlawful confinement of a person against their will, often including transportation/asportation. The asportation and abduction element is typically but not necessarily conducted by means of force or fear: the perpetrator may use a weapon to force the victim into a vehicle, but it is still kidnapping if the victim is enticed to enter the vehicle willingly (e.g. in the belief that it is a taxicab). Kidnapping may be done to demand for ransom in exchange for releasing the victim, or for other illegal purposes. Kidnapping can be accompanied by bodily injury which elevates the crime to aggravated kidnapping. Kidnapping of a child is known as child abduction, which is a separate legal category. Motivations Kidnapping of children is usually done by one parent or others. The kidnapping of adults is often for ransom or to force someone to withdraw money from an Automated teller machine, ATM, but may also be for sexual assault. Children have also been ...
