Salmonella
''Salmonella'' is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two 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 2,600 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 ATP with oxygen ("aerobically") when it is available, or using other electron acceptors or fermentation ("anaerobically") when oxygen is not available. ''Salmonella'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stained Glass
Stained glass is coloured glass as a material or works created from it. Throughout its thousand-year history, the term has been applied almost exclusively to the windows of churches and other significant religious buildings. Although traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture. Modern vernacular usage has often extended the term "stained glass" to include domestic lead light and ''objets d'art'' created from foil glasswork exemplified in the famous lamps of Louis Comfort Tiffany. As a material ''stained glass'' is glass that has been coloured by adding metallic salts during its manufacture, and usually then further decorating it in various ways. The coloured glass is crafted into ''stained glass windows'' in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead and supported by a rigid frame.

Judith Schaechter
Judith Schaechter is a Philadelphia-based artist known for her work in the medium of stained glass. Her pieces often use symbolism from stained glass and Gothic traditions, but the distorted faces and figures in her work recall a 20th century German Expressionist painting style and her subject matter is secular. Shaechter's work often involves images that might be considered disturbing such as death, disease, or violence. Early Schaechter pieces, for example, such as King of Maggots' and ''Vide Futentes'' make use of memento mori, symbols of death found in church architecture during medieval times. Biography Schaechter was born in Gainesville, Florida, in 1961, but spent her formative years growing up in Massachusetts. She has served on the faculty of numerous art schools, such as the Rhode Island School of Design. She is currently an Adjunct Professor in the Crafts Department at The University of the Arts in Philadelphia, Pennsylvania and Adjunct Faculty at the New York Acade ...

DNA Methylation
DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. In mammals, DNA methylation is essential for normal development and is associated with a number of key processes including genomic imprinting, X-chromosome inactivation, repression of transposable elements, aging, and carcinogenesis. As of 2016, two nucleobases have been found on which natural, enzymatic DNA methylation takes place: adenine and cytosine. The modified bases are N6-methyladenineD. B. Dunn, J. D.

Origin Of Replication
The origin of replication (also called the replication origin) is a particular sequence in a genome at which replication is initiated. Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full complement of chromosomes. Material was copied from this source, which is available under Creative Commons Attribution 4.0 International License This can either involve the replication of DNA in living organisms such as prokaryotes and eukaryotes, or that of DNA or RNA in viruses, such as double-stranded RNA viruses. Synthesis of daughter strands starts at discrete sites, termed replication origins, and proceeds in a bidirectional manner until all genomic DNA is replicated. Despite the fundamental nature of these events, organisms have evolved surprisingly divergent strategies that control replication onset. Although the specific replication o ...

Cell Membrane
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of all cells from the outside environment (the extracellular space). The cell membrane consists of a lipid bilayer, made up of two layers of phospholipids with cholesterols (a lipid component) interspersed between them, maintaining appropriate membrane fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that span the membrane and serve as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes to facilitate interaction with the cell's environment. Glycolipids embedded in the outer lipid layer serve a similar purpose. The cell membrane controls the movement of substances in and out of cells and organelles, being selectively permeable to ions a ...

Cell Division
Cell division is the process by which a parent cell (biology), cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome(s) before dividing. In eukaryotes, there are two distinct types of cell division: a vegetative division (mitosis), producing daughter cells genetically identical to the parent cell, and a cell division that produces Haploidisation, haploid gametes for sexual reproduction (meiosis), reducing the number of chromosomes from two of each type in the diploid parent cell to one of each type in the daughter cells. In cell biology, mitosis (Help:IPA/English, /maɪˈtoʊsɪs/) is a part of the cell cycle, in which, replicated chromosomes are separated into two new Cell nucleus, nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. In general, mitosis (division of the nucleus) is preceded by the S stage of interph ...

Science Communication
Science communication is the practice of informing, educating, raising awareness of science-related topics, and increasing the sense of wonder about scientific discoveries and arguments. Science communicators and audiences are ambiguously defined and the expertise and level of science knowledge varies with each group. Two types of science communication are outward-facing or science outreach (typically conducted by professional scientists to non-expert audiences) and inward-facing or science "inreach" (expert to expert communication from similar or different scientific backgrounds). Examples of outreach include science journalism and science museums. Examples of inreach include scholarly communication and publication in scientific journals. But science communication is influenced by systemic inequalities that impact both inreach and outreach. Science communicators can use entertainment and persuasion including humour, storytelling and metaphors. Scientists can be trained in ...

Adjunct Professor
An adjunct professor is a type of academic appointment in higher education who does not work at the establishment full-time. The terms of this appointment and the job security of the tenure vary in different parts of the world, however the general definition is agreed upon. The term "Adjuncting" is a way of referring to a bona-fide part-time faculty member who has worked in an adjunct position for an institution of higher education. Terminology They may also be called an adjunct lecturer, adjunct instructor, or adjunct faculty. Collectively, they may be referred to as contingent academic labor. The rank of sessional lecturer in Canadian universities is similar to the US concept. North America In the United States, an adjunct is, in most cases, a non-tenure-track faculty member. However, it can also be a scholar or teacher whose primary employer is not the school or department with which they have adjunct status. Adjunct professors make up the majority of instructors in high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
