SGR 1935 2154
SGR 1935+2154 (or SGR J1935+2154) is a soft gamma repeater (SGR) that is an ancient stellar remnant, in the constellation Vulpecula, originally discovered in 2014 by the Neil Gehrels Swift Observatory. Currently, the SGR-phenomena and the related anomalous X-ray pulsars (AXP) are explained as arising from magnetars. On 28 April 2020, this remnant about away in our Milky Way galaxy was observed to be associated with a very powerful radio pulse known as a fast radio burst or FRB (designated FRB 200428), and a related x-ray flare. The detection is notable as the first FRB detected ''inside'' the Milky Way, and the first to be linked to a known source. Later in 2020, SGR 1935+2154 was found to be associated with ''repeating'' fast radio bursts. History The Swift Burst Alert Telescope first alerted the astronomical community to an increase in activity from the remnant with the detection of a flare on 27 April 2020. The next day, the Canadian Hydrogen Intensity Mapping Experimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart Colchester
Heart Colchester (formerly SGR Colchester) was a radio station broadcasting to Colchester and the surrounding areas. The station was launched in 1993 as SGR Colchester by the East Anglian Radio group, which also operated the Ipswich-based SGR-FM, Radio Broadland in Norwich, and Amber Radio across Suffolk and Norfolk. History The station, serving a population of around 150,000, broadcast programmes from its studios in the town during daytime (6am - 6pm) but shared output from its larger sister SGR station in Ipswich at other times. The Colchester station was an immediate success and quickly built an impressive audience locally, soon establishing itself as market leader. Staff in the early years included Mike Stewart (group programme director), Danny Cox (station manager) and presenters Nick Jackson and Simon Taylor. It became part of the GWR Group when East Anglian Radio was taken over in 1996. In January 2009, owners Global Radio re-branded SGR Colchester as ''Heart Colchester' ...

Specific Growth Rate
Relative growth rate (RGR) is growth rate relative to size - that is, a rate of growth per unit time, as a proportion of its size at that moment in time. It is also called the exponential growth Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. Described as a function, a ... rate, or the continuous growth rate. Rationale RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if S is the current size, and \frac its growth rate, then relative growth rate is :\frac\frac. If the relative growth rate is constant, i.e., :\frac\frac = k, a solution to this equation is :S_t = \exp^. A closely related concept is doubling time. Calculations In the simplest case of obse ...

Medicare Sustainable Growth Rate
The Medicare Sustainable Growth Rate (SGR) was a method used by the Centers for Medicare and Medicaid Services (CMS) in the United States to control spending by Medicare (United States), Medicare on physician services. President Barack Obama signed a bill into law on April 16, 2015, the Medicare Access and CHIP Reauthorization Act of 2015, which ended use of the SGR. The measure went into effect in July 2015. Enacted by the Balanced Budget Act of 1997 to amend Section 1848(f) of the Social Security Act, the SGR replaced the ''Medicare Volume Performance Standard'' (MVPS), which was the previous method that CMS used in an attempt to control costs. Generally, this was a method to ensure that the yearly increase in the expense per Medicare beneficiary did not exceed the growth in GDP. Every year, the CMS sent a report to the Medicare Payment Advisory Commission, which advised the United States Congress, U.S. Congress on the previous year's total expenditures and the target expenditu ...

Sustainable Growth Rate
According to PIMS (profit impact of marketing strategy), an important lever of business success is growth. Among 37 variables, growth is mentioned as one of the most important variables for success: market share, market growth, marketing expense to sales ratio or a strong market position. The question how much growth is sustainable is answered by two concepts with different perspectives: * The sustainable growth rate (SGR) concept by Robert C. Higgins, describes optimal growth from a financial perspective assuming a given strategy with clear defined financial frame conditions/ limitations. Sustainable growth is defined as the annual percentage of increase in sales that is consistent with a defined financial policy (target debt to equity ratio, target dividend payout ratio, target profit margin, target ratio of total assets to net sales). This concept provides a comprehensive financial framework and formula for case/ company specific SGR calculations. * The optimal growth concept ...

Neuroglia
Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses. They maintain homeostasis, form myelin in the peripheral nervous system, and provide support and protection for neurons. In the central nervous system, glial cells include oligodendrocytes, astrocytes, ependymal cells, and microglia, and in the peripheral nervous system they include Schwann cells and satellite cells. Function They have four main functions: *to surround neurons and hold them in place *to supply nutrients and oxygen to neurons *to insulate one neuron from another *to destroy pathogens and remove dead neurons. They also play a role in neurotransmission and synaptic connections, and in physiological processes such as breathing. While glia were thought to outnumber neurons by a ratio of 10:1, recent studies using newer methods and reappraisal of historical qu ...

Substantia Gelatinosa Of Rolando
The apex of the posterior grey column, one of the three grey columns of the spinal cord, is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando (or SGR) (or gelatinous substance of posterior horn of spinal cord), which contains both neuroglia cells, and small nerve cells. The gelatinous appearance is due to a very low concentration of myelinated fibers. It extends the entire length of the spinal cord and into the medulla oblongata where it becomes the spinal nucleus of the trigeminal nerve. It is named after Luigi Rolando. It corresponds to Rexed lamina II. Structure The SGR, or Rexed laminae, lamina II, is composed of an outer lamina II and an inner lamina II. In rodents, the inner lamina II is divided into a dorsal and ventral inner lamina II. The distinction between these laminae lies in the areas of the spinal cord that send information to and from the laminae (input and output projections). The cell ...

Mombasa–Nairobi Standard Gauge Railway
The Mombasa–Nairobi Standard Gauge Railway is a standard-gauge railway (SGR) in Kenya that connects the large Indian Ocean city of Mombasa with Nairobi, the country's capital and largest city. This SGR runs parallel to the narrow-gauge Uganda Railway that was completed in 1901 under British colonial rule. The East African Railway Master Plan provides for the Mombasa–Nairobi SGR to link with other SGRs being built in the East African Community. At a cost of , the SGR was among Kenya's most expensive infrastructure projects as at the time it was launched. The prime contractor was the China Road & Bridge Corporation CRBC, which hired 25,000 Kenyans to work on the railway. CRBC's holding company, China Communications Construction Company is contracted to operate the line for its first five years. As of 2020, railway operation expenses exceeded revenues. An extension from Nairobi to Suswa was completed in October 2019 extending the line's length to approximately . The first fa ...
