Nutshell
A nutshell is the outer shell of a nut. Most nutshells are inedible and are removed before eating the nut meat inside. It covers and protects the kernel, which may be edible. Usage Most nutshells are useful to some extent, depending on the circumstances. Walnut shells can be used for cleaning and polishing, as a filler in dynamite, and as a paint thickening agent. Shells from pecans, almonds, Brazil nuts, acorns, and most other nuts are useful in composting. Their high porosity makes them also ideal in the production of activated carbon by pyrolysis. Shells can also be used as loose-fill packing material, to protect fragile items in shipping. Idiomatic usage The expression "in a nutshell" (of a story, proof, etc.) means "in essence", metaphorically alluding to the fact that the essence of the nut – its edible part – is contained inside its shell. The expression further gave rise to the journalistic term '' nut graph'', short for ''nutshell paragraph''. In ''Hamlet'' ...

Brazil Nuts
The Brazil nut (''Bertholletia excelsa'') is a South American tree in the family Lecythidaceae, and it is also the name of the tree's commercially harvested edible seeds. It is one of the largest and longest-lived trees in the Amazon rainforest. The fruit and its nutshell – containing the edible Brazil nut (fruit), nut – are relatively large and weigh as much as in total. As food, Brazil nuts are notable for diverse content of micronutrients, especially a high amount of selenium. The wood of the Brazil nut tree is prized for its quality in carpentry, flooring, and heavy construction.

Activated Carbon
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area available for ''adsorption '' or chemical reactions. (Adsorption, not to be confused with Absorption (chemistry), absorption, is a process where atoms or molecules adhere to a surface). The pores can be thought of as a microscopic "sponge" structure. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. ''Activated'' is sometimes replaced by ''active''. Because it is so porous on a microscopic scale, one gram of activated carbon has a surface area of over , as determined by gas absorption and its porosity can run 10ML/day in terms of treated water per gram. Researchers at Cornell University synthesized an ultrahigh surface area activated ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrolysis
Pyrolysis is a process involving the Bond cleavage, separation of covalent bonds in organic matter by thermal decomposition within an Chemically inert, inert environment without oxygen. Etymology The word ''pyrolysis'' is coined from the Greek language, Greek-derived morpheme, elements ''pyro-'' (from Ancient Greek : - "fire, heat, fever") and ''lysis'' ( : - "separation, loosening"). Applications Pyrolysis is most commonly used in the treatment of organic compound, organic materials. It is one of the processes involved in the charring of wood or pyrolysis of biomass. In general, pyrolysis of organic substances produces volatile products and leaves Char (chemistry), char, a carbon-rich solid residue. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization. Pyrolysis is considered one of the steps in the processes of gasification or combustion. Laypeople often confuse pyrolysis gas with syngas. Pyrolysis gas has a high percentage of heavy tar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nut (fruit)
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, many dry seeds are called nuts, but in a botanical context, "nut" implies that the shell does not open to release the seed (Dehiscence (botany), indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. Definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into a new plant, stored food for the embryo, and a protective seed coat. Botany, Botanically, a nut is a fruit with a woody pericarp developing from a syncarpous gynoecium. Nuts may be contained in an Bract#Involucral bracts, involucre, a cup-shaped structure formed from the flower bracts. The involucre may be scaly, spiny, leafy or tubular, depending ...

Journalism
Journalism is the production and distribution of reports on the interaction of events, facts, ideas, and people that are the "news of the day" and that informs society to at least some degree of accuracy. The word, a noun, applies to the journalist, occupation (professional or not), the methods of gathering information, and the organizing literary styles. The appropriate role for journalism varies from country to country, as do perceptions of the profession, and the resulting status. In some nations, the news media are controlled by government and are not independent. In others, news media are independent of the government and operate as private industry. In addition, countries may have differing implementations of laws handling the freedom of speech, freedom of the press as well as slander and Libel, libel cases. The proliferation of the Internet and smartphones has brought significant changes to the media landscape since the turn of the 21st century. This has created a shif ...

Metaphors Referring To Plants
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide, or obscure, clarity or identify hidden similarities between two different ideas. Metaphors are usually meant to create a likeness or an analogy. Analysts group metaphors with other types of figurative language, such as antithesis, hyperbole, metonymy, and simile. According to Grammarly, "Figurative language examples include similes, metaphors, personification, hyperbole, allusions, and idioms." One of the most commonly cited examples of a metaphor in English literature comes from the "All the world's a stage" monologue from ''As You Like It'': All the world's a stage, And all the men and women merely players; They have their exits and their entrances And one man in his time plays many parts, His Acts being seven ages. At first, the infant... :—William Shakespeare, ''As You Like It'', 2/7 This quotation expresses a metaphor because the world is n ...

Plant Anatomy
Plant anatomy or phytotomy is the general term for the study of the internal Anatomy, structure of plants. Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure. Plant anatomy is now frequently investigated at the Plant cell, cellular level, and often involves the sectioning of tissue (biology), tissues and microscopy. Structural divisions Some studies of plant anatomy use a systems approach, organized on the basis of the plant's activities, such as nutrient transport, flowering, pollination, embryogenesis or seed development. Others are more classically divided into the following structural categories: * Flower anatomy, including study of the Sepal, calyx, Corolla (flower), corolla, androecium, and gynoecium * Leaf#Anatomy (medium and small scale), Leaf anatomy, including study of the Epidermis ...

Homer
Homer (; , ; possibly born ) was an Ancient Greece, Ancient Greek poet who is credited as the author of the ''Iliad'' and the ''Odyssey'', two epic poems that are foundational works of ancient Greek literature. Despite doubts about his authorship, Homer is considered one of the most revered and influential authors in history. The ''Iliad'' centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The ''Odyssey'' chronicles the ten-year journey of Odysseus, king of Homer's Ithaca, Ithaca, back to his home after the fall of Troy. The epics depict man's struggle, the ''Odyssey'' especially so, as Odysseus perseveres through the punishment of the gods. The poems are in Homeric Greek, also known as Epic Greek, a literary language that shows a mixture of features of the Ionic Greek, Ionic and Aeolic Greek, Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iliad
The ''Iliad'' (; , ; ) is one of two major Ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the ''Odyssey'', the poem is divided into 24 books and was written in dactylic hexameter. It contains 15,693 lines in its most widely accepted version. The ''Iliad'' is often regarded as the first substantial piece of Western literature, European literature and is a central part of the Epic Cycle. Set towards the end of the Trojan War, a ten-year siege of the city of Troy by a coalition of Mycenaean Greece, Mycenaean Greek states, the poem depicts significant events in the war's final weeks. In particular, it traces the anger () of Achilles, a celebrated warrior, from a fierce quarrel between him and King Agamemnon, to the death of the Trojan prince Hector.Homer, ''Iliad, Volume I, Books 1–12'', translated by A.

Cicero
Marcus Tullius Cicero ( ; ; 3 January 106 BC – 7 December 43 BC) was a Roman statesman, lawyer, scholar, philosopher, orator, writer and Academic skeptic, who tried to uphold optimate principles during the political crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics. He is considered one of Rome's greatest orators and prose stylists and the innovator of what became known as "Ciceronian rhetoric". Cicero was educated in Rome and in Greece. He came from a wealthy municipal family of the Roman equestrian order, and served as consul in 63 BC. He greatly influenced both ancient and modern reception of the Latin language. A substantial part of his work has survived, and he was admired by both ancient and modern authors alike. Cicero adapted the arguments of the chief schools of Hellenistic philosophy in Latin and coined a large portion of Latin philosophical vocabulary via ...

Natural History (Pliny)
The ''Natural History'' () is a Latin work by Pliny the Elder. The largest single work to have survived from the Roman Empire to the modern day, the ''Natural History'' compiles information gleaned from other ancient authors. Despite the work's title, its subject area is not limited to what is today understood by natural history; Pliny himself defines his scope as "the natural world, or life". It is encyclopedic in scope, but its structure is not like that of a modern encyclopedia. It is the only work by Pliny to have survived, and the last that he published. He published the first 10 books in AD 77, but had not made a final revision of the remainder at the time of Pliny the Elder#Death, his death during the Eruption of Mount Vesuvius in 79 AD, AD 79 eruption of Vesuvius. The rest was published posthumously by Pliny's nephew, Pliny the Younger. The work is divided into 37 books, organised into 10 volumes. These cover topics including astronomy, mathematics, geography, ethn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
