Herbar Digital
Herbar Digital is a research project at the Fachhochschule Hannover (FHH) from 2006 to 2011 for rationalising the virtualization of botanical document material and their usage by process optimization and automation. Research project Conservatively estimated, 500 million dried plants — so called herbar specimens — are stored in herbariums at botanic gardens across the world under scientifically controlled conditions. The aim of the third-party-funds financed research project is to automate the process of virtualization of herbar specimens and their management to make them digitally accessible to botanists and biologists. An examplary solution for the example herbarium of the botanic Garden in Berlin-Dahlem (ca. 3.5 million plant specimens) will allow to generalize the applied structure, software and technique to a level from that general reference solutions for efficient high-resolution scanning of any object of museum quality can be derived.

Herbar Digital 01
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called '' exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types, some may be specimens distributed in series called exsiccatae. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin.

DIN A3
ISO 216 is an International Organization for Standardization, international standard for paper sizes, used around the world except in North America and parts of Latin America. The standard defines the "A", "B" and "C" series of paper sizes, including A4, the most commonly available paper size worldwide. Two supplementary standards, ISO 217 and ISO 269, define related paper sizes; the ISO 269 "C" series is commonly listed alongside the A and B sizes. All ISO 216, ISO 217 and ISO 269 paper sizes (except some envelopes) have the same aspect ratio, square root of 2, , within rounding to millimetres. This ratio has the unique property that when cut or folded in half widthways, the halves also have the same aspect ratio. Each ISO paper size is one half of the area of the next larger size in the same series. Dimensions of A, B and C series History The oldest known mention of the advantages of basing a paper size on an aspect ratio of is found in a letter written on 25 Octob ...

2006 Establishments In Germany
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Herbarium
In botany, a virtual herbarium is a herbarium in a digitized form. That is, it concerns a collection of digital images of preserved plants or plant parts. Virtual herbaria often are established to improve availability of specimens to a wider audience. However, there are digital herbaria that are not suitable for internet access because of the high resolution of scans and resulting large file sizes (several hundred megabytes per file). Additional information about each specimen, such as the location, the collector, and the botanical name are attached to every specimen. Frequently, further details such as related species and growth requirements are mentioned. Specimen imaging The standard hardware used for herbarium specimen imaging is the "HerbScan" scanner. It is an inverted flat-bed scanner which raises the specimen up to the scanning surface. This technology was developed because it is standard practice to never turn a herbarium specimen upside-down. Alternatively, some herbar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pentacon
Pentacon is the company name of a camera manufacturer in Dresden, Germany. The name Pentacon is derived from the brand Contax of Zeiss Ikon Kamerawerke in Dresden and Pentagon In geometry, a pentagon (from the Greek πέντε ''pente'' meaning ''five'' and γωνία ''gonia'' meaning ''angle'') is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simpl ..., as a Pentaprism for Single-Lens Reflex (SLR) cameras was for the first time developed in Dresden. The cross section of this prism has a pentagonal shape. Pentacon is best known for producing the SLR cameras of the Praktica-series as well as the medium format camera Pentacon Six, the Pentacon Super and various cameras of the Exa series. Pentacon also produced slide projectors.
