Bulk Cargo
Bulk cargo is commodity cargo that is transported unpackaged in large quantities. Description Bulk cargo refers to material in either liquid or granular, particulate form, as a mass of relatively small solids, such as petroleum/ crude oil, grain, coal, or gravel. This cargo is usually dropped or poured, with a spout or shovel bucket, into a bulk carrier ship's hold, railroad car/ railway wagon, or tanker truck/ trailer/semi-trailer body. Smaller quantities can be boxed (or drummed) and palletised; cargo packaged in this manner is referred to as breakbulk cargo. Bulk cargo is classified as liquid or dry. The Baltic Exchange is based in London and provides a range of indices benchmarking the cost of moving bulk commodities, dry and wet, along popular routes around the seas. Some of these indices are also used to settle Freight Futures, known as FFA's. The most famous of the Baltic indices is the Baltic Dry Indices, commonly called the BDI. This is a derived function ...

Bulk Modulus
The bulk modulus (K or B) of a substance is a measure of how resistant to compression the substance is. It is defined as the ratio of the infinitesimal pressure increase to the resulting ''relative'' decrease of the volume. Other moduli describe the material's response (strain) to other kinds of stress: the shear modulus describes the response to shear stress, and Young's modulus describes the response to normal (lengthwise stretching) stress. For a fluid, only the bulk modulus is meaningful. For a complex anisotropic solid such as wood or paper, these three moduli do not contain enough information to describe its behaviour, and one must use the full generalized Hooke's law. The reciprocal of the bulk modulus at fixed temperature is called the isothermal compressibility. Definition The bulk modulus K (which is usually positive) can be formally defined by the equation :K=-V\frac , where P is pressure, V is the initial volume of the substance, and dP/dV denotes the derivative of ...

Bulk And Skull
Farkas "Bulk" Bulkmeier and Eugene "Skull" Skullovitch are fictional characters in the Power Rangers universe. They appeared as permanent cast members from ''Mighty Morphin Power Rangers'' until ''Power Rangers in Space''. Bulk was a recurring character in ''Power Rangers Lost Galaxy'', along with ''Power Rangers Samurai'' and '' Power Rangers Super Samurai'', but the duo never returned together as permanent cast members. Bulk and Skull are portrayed by Paul Schrier and Jason Narvy respectively. Character overview Bulk was the dominant member of the duo. His appearance resembled a heavyset teenage punk. Skull was lean and wore more formal attire. Skull often emulated Bulk's behavior or agreed with his statements. The duo provided slapstick comic relief to the franchise. The duo came with their own theme; a musical combo of Skull's whiny laugh and Bulk's "fat guy tuba." Their actions were punctuated by cartoon sound effects.

UK Pitbulls
The UK Pitbulls are a professional wrestling tag team that consists of brothers Bulk (Mike Waters, born 1978) and Big Dave (Dave Waters, born 1971). They previously held a number of titles in the United Kingdom, United States, as well as 11 countries worldwide. Their career as a tag team ended for some years when Dave sustained an injury in a strongman contest. They held 20 tag team championships. They were named "England's Most Dominant Tag Team" by ''Total Wrestling Magazine''. After Big Dave's injury and a sustained period of rehab over many years the pair are wrestling again as the UK Pitbulls and have featured in Fightmare Norwich 2019. Professional wrestling career Dave was originally trained by Andre Baker at NWA UK Hammerlock. Dave and Mike completed their training in late 1997 at World Association of Wrestling (WAW) of Norwich under Sweet Saraya. The UK Pitbulls name is actually a play on the World Wrestling Federation's British Bulldogs tag team name; Bulk and Big Dave ...

Universe
The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together ago, and the universe has been expanding ever since the Big Bang. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day. Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus's work as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AdS/CFT Correspondence
In theoretical physics, the anti-de Sitter/conformal field theory correspondence, sometimes called Maldacena duality or gauge/gravity duality, is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces (AdS) which are used in theories of quantum gravity, formulated in terms of string theory or M-theory. On the other side of the correspondence are conformal field theories (CFT) which are quantum field theories, including theories similar to the Yang–Mills theories that describe elementary particles. The duality represents a major advance in the understanding of string theory and quantum gravity.de Haro et al. 2013, p. 2 This is because it provides a non-perturbative formulation of string theory with certain boundary conditions and because it is the most successful realization of the holographic principle, an idea in quantum gravity originally proposed by Gerard 't Hooft and promoted by Leonard Susskind. It also provides a powerf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M-theory
M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995. Witten's announcement initiated a flurry of research activity known as the second superstring revolution. Prior to Witten's announcement, string theorists had identified five versions of superstring theory. Although these theories initially appeared to be very different, work by many physicists showed that the theories were related in intricate and nontrivial ways. Physicists found that apparently distinct theories could be unified by mathematical transformations called S-duality and T-duality. Witten's conjecture was based in part on the existence of these dualities and in part on the relationship of the string theories to a field theory called eleven-dimensional supergravity. Although a complete formulation of M-theory is not known, such a formu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brane Cosmology
Brane cosmology refers to several theories in particle physics and cosmology related to string theory, superstring theory and M-theory. Brane and bulk The central idea is that the visible, three-dimensional universe is restricted to a brane inside a higher-dimensional space, called the "bulk" (also known as "hyperspace"). If the additional dimensions are compact, then the observed universe contains the extra dimension, and then no reference to the bulk is appropriate. In the bulk model, at least some of the extra dimensions are extensive (possibly infinite), and other branes may be moving through this bulk. Interactions with the bulk, and possibly with other branes, can influence our brane and thus introduce effects not seen in more standard cosmological models. Why gravity is weak and the cosmological constant is small Some versions of brane cosmology, based on the large extra dimension idea, can explain the weakness of gravity relative to the other fundamental forces of nat ...

Bulk Density
Bulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff, or any other masses of corpuscular or particulate matter (particles). Bulk density is defined as the mass of the many particles of the material divided by the total volume they occupy. The total volume includes particle volume, inter-particle void volume, and internal pore volume. Bulk density is not an intrinsic property of a material; it can change depending on how the material is handled. For example, a powder poured into a cylinder will have a particular bulk density; if the cylinder is disturbed, the powder particles will move and usually settle closer together, resulting in a higher bulk density. For this reason, the bulk density of powders is usually reported both as "freely settled" (or "poured" density) and "tappe ...

Bulk Liquids
Bulk cargo is commodity cargo that is transported unpackaged in large quantities. Description Bulk cargo refers to material in either liquid or granular, particulate form, as a mass of relatively small solids, such as petroleum/ crude oil, grain, coal, or gravel. This cargo is usually dropped or poured, with a spout or shovel bucket, into a bulk carrier ship's hold, railroad car/ railway wagon, or tanker truck/ trailer/semi-trailer body. Smaller quantities can be boxed (or drummed) and palletised; cargo packaged in this manner is referred to as breakbulk cargo. Bulk cargo is classified as liquid or dry. The Baltic Exchange is based in London and provides a range of indices benchmarking the cost of moving bulk commodities, dry and wet, along popular routes around the seas. Some of these indices are also used to settle Freight Futures, known as FFA's. The most famous of the Baltic indices is the Baltic Dry Indices, commonly called the BDI. This is a derived functio ...

Bulk Fermentation
Straight dough is a single-mix process of making bread. The dough is made from all fresh ingredients, and they are all placed together and combined in one kneading or mixing session. After mixing, a bulk fermentation rest of about 1 hour or longer occurs before division. It is also called the direct dough method. Formula A straight dough formula might look like this: : Process In general, the process steps for making straight dough are as follows: *Mise en place: The first step is to look at the formula ("recipe"), familiarize yourself with the ingredients and process, get ready to perform the task at hand. Assess the availability of tools, consider the batch size and time schedule, and gather what is needed. *Weigh ingredients: This is also called scaling. If more yeast is chosen for the initial mixing and it is viable, faster fermentation occurs. If too much yeast is used the result is a noticeable yeast flavor. *Mixing: The ingredients are all placed in a mixing bowl a ...

Bulk Purchasing
Bulk purchasing or mass buying is the purchase of much larger quantities than the usual, for a unit price that is lower than the usual. Wholesaling is selling goods in large quantities at a low unit price to retail merchants. The wholesaler will accept a slightly lower sales price for each unit, if the retailer will agree to purchase a much greater quantity of units, so the wholesaler can maximize profit. A wholesaler usually represents a factory where goods are produced. The factory owners can use economy of scale to increase profit as the quantity sold increases. Retailing is buying goods in a wholesale market to sell them in small quantities at higher prices to consumers. Part of this profit is justified by logistics, the useful distribution function of the retailer, who delivers the goods to consumers and divides those large quantities of goods into many smaller units suitable for many transactions with many small parties of consumers. Retailers can also benefit from eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
