Analytical Chemistry
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemotaxonomy
Webster's Dictionary, Merriam-Webster defines ''chemotaxonomy'' as the method of biology, biological classification based on similarities and dissimilarity in the structure of certain chemical compound, compounds among the organisms being classified. Advocates argue that, as proteins are more closely controlled by genes and less subjected to natural selection than the anatomy, anatomical features, they are more reliable indicators of genetic distance, genetic relationships. The compounds studied most are proteins, amino acids, nucleic acids, peptides etc. Physiology is the study of working of organ (anatomy), organs in a List of life forms, living being. Since working of the organs involves chemicals of the human body, body, these compounds are called biochemical, biochemical evidences. The study of Morphology (biology), morphological change has shown that there are changes in the anatomy, structure of animals which result in evolution. When changes take place in the structure of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytochemistry
Phytochemistry is the study of phytochemicals, which are chemicals derived from plants. Phytochemists strive to describe the structures of the large number of secondary metabolites found in plants, the functions of these compounds in human and plant biology, and the biosynthesis of these compounds. Plants synthesize phytochemicals for many reasons, including to protect themselves against insect attacks and plant diseases. The compounds found in plants are of many kinds, but most can be grouped into four major biosynthetic classes: alkaloids, phenylpropanoids, polyketides, and terpenoids. Phytochemistry can be considered a subfield of botany or chemistry. Activities can be led in botanical gardens or in the wild with the aid of ethnobotany. Phytochemical studies directed toward human (i.e. drug discovery) use may fall under the discipline of pharmacognosy, whereas phytochemical studies focused on the ecological functions and evolution of phytochemicals likely fall under the disci ...

Melbourne University Press
Melbourne University Publishing (MUP) is the book publishing arm of the University of Melbourne. History MUP was founded in 1922 as Melbourne University Press to sell text books and stationery to students, and soon began publishing books itself. Over the years scholarly works published under the MUP imprint have won numerous awards and prizes. The name ''Melbourne University Publishing'' was adopted for the business in 2003 following a restructure by the university, but books continue to be published under the ''Melbourne University Press'' imprint. The Miegunyah Press is an imprint of MUP, established in 1967 under a bequest from businessman and philanthropist Russell Grimwade, with the intention of subsidising the publication of illustrated scholarly works that would otherwise be uneconomic to publish. Grimwade's great-grandnephew Andrew Grimwade is the present patron. ''Miegunyah'' is from an Aboriginal Australian language, meaning "my house".

Queen Elizabeth II Silver Jubilee Medal
The Queen Elizabeth II Silver Jubilee Medal (french: link=no, Médaille du jubilé d'argent de la reine Elizabeth II) is a commemorative medal created in 1977 to mark the 25th anniversary of Queen Elizabeth II's accession in 1952. The medal is physically identical in all realms where it was awarded, save for Canada, where it contained unique elements. As an internationally distributed award, the Queen Elizabeth II Silver Jubilee Medal holds a different place in each country's order of precedence for honours. Basis of award and numbers awarded The Queen Elizabeth II Silver Jubilee Medal was created by a Royal Warrant from the Queen. Until 1977, the practice for coronation and jubilee medals was for the United Kingdom authorities to decide on a total number of medals to be produced and allocate how many were to be distributed by each Dominion and possession across the British Empire, and later, to each Commonwealth country. From 1977, the award of the medals was at the discreti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
