Brussels Ring
The Brussels Ring ( or ; ), numbered R0, is a ring road surrounding the Brussels-Capital Region, as well as other smaller towns south of Brussels. It is about long, with two or three lanes in each direction. While most of it is classified as a motorway (highway), part of it (in the Sonian Forest) is merely an express route. It crosses the three regions of Belgium: its main part () is situated in Flanders, whereas Wallonia comprises of the total stretch and is on Brussels territory. The clockwise carriageway is referred to as the ''inner ring'' (, ), while the anticlockwise carriageway is referred to as the ''outer ring'' (, ). History The first sections of the road were built in the late 1950s, but the main part was built during the 1970s, with the end of construction in 1978. The Brussels Ring has interchanges with the European routes E40 (at the Groot-Bijgaarden and Sint-Stevens-Woluwe interchanges), E19 (at the Machelen and Ittre interchanges), E411 (at the Leonard ...

Haplogroup R0
Haplogroup R0 (formerly known as haplogroup pre-HV) is a human mitochondrial DNA (mtDNA) haplogroup. Origin Haplogroup R0 derives from the macro-haplogroup R. It is an ancestral clade to the R0a subclade and haplogroup HV, and is therefore antecedent to the haplogroups H and V. R0's greater subclade variety in the Arabian Peninsula suggests that the clade originated in and spread from there. R0a is believed to have evolved in Ice Age oases in South Arabia around 22,000 years ago. The subclade would then have spread from there with the onset of the Late Glacial period circa 15,000 ybp. Distribution Haplogroup R0 has been found in around 55% of osteological remains belonging to the Eneolithic Trypillia culture. The R0 clade has also been found among Iberomaurusian specimens at the Taforalt and Afalou prehistoric sites, which date from the Epipaleolithic. Among the Taforalt individuals, around 17% of the observed haplotypes belonged to various R0 subclades, including R0a1a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Reproduction Number
In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted R_0 (pronounced ''R nought'' or ''R zero''), of an infection is the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. The definition assumes that no other individuals are infected or immunized (naturally or through vaccination). Some definitions, such as that of the Australian Department of Health, add the absence of "any deliberate intervention in disease transmission". The basic reproduction number is not necessarily the same as the effective reproduction number R (usually written R_t 't'' for "time" sometimes R_e), which is the number of cases generated in the current state of a population, which does not have to be the uninfected state. R_0 is a dimensionless number (persons infected per person infecting) and not a time rate, which would have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net Reproduction Rate
In population ecology and demography, the net reproduction rate, ''R''0, is the average number of offspring (often specifically daughters) that would be born to a female if she passed through her lifetime conforming to the age-specific fertility and mortality rates of a given year. This rate is similar to the gross reproduction rate but takes into account that some females will die before completing their childbearing years. An ''R''0 of one means that each generation of mothers is having exactly enough daughters to replace themselves in the population. If the R0 is less than one, the reproductive performance of the population is below replacement level. The ''R''0 is particularly relevant where sex ratios at birth are significantly affected by the use of reproductive technologies, or where life expectancy is low. The current (2015–20) estimate for the R0 worldwide under the UN's medium variant model is 1.09 daughters per woman. See also * List of countries by net reproducti ...

Samsung YP-R0
The Samsung YP-R0 (also known as Samsung R0 worldwide or Yepp R0 in South Korea, Korea or Samsung R'PLAY in France) is a portable media player made by Samsung Electronics, Samsung, leaked on August 10, 2009 and first released end of October 2009 in Russia. It was developed along with the YP-R1 with which it shares several specifications (similar aluminum design, same Linux kernel and System on a chip, SoC). The R0 is available in three different Flash memory capacities: 4 GB, 8 GB, and 16 GB. It comes in three different colors: black, silver and pink. Storage is expandable via a microSDHC slot with capacity up to 32 GB, and unofficially to 64 GB or more via FAT32 formatted SDXC cards. It features an aluminum case, a 2.6 inch TFT LCD display with a resolution of 240 by 320 pixels, Radio Data System, RDS FM broadcasting, FM tuner, tactile buttons and microUSB connector. Several EQ and sound effects are available through Samsung's ''DNSe 3.0'' sound engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
