R. H. Hunt

Reuben Harrison Hunt (February 2, 1862 – May 28, 1937), also known as R. H. Hunt, was an American architect who spent most of his life in Chattanooga, Tennessee. He is considered to have been one of the city's most significant early architects. He also designed major public building projects in other states.

He came to Chattanooga in 1882 and within four years had established a successful architectural firm. Hunt designed a number of Chattanooga's homes and public buildings, including the Soldiers and Sailors Memorial Auditorium (1922), the Joel W. Solomon Federal Building and U.S. Courthouse (1934) with Shreve, Lamb and Harmon, the Hamilton County, Tennessee Courthouse (1912), the James (1907) and Maclellan (1924) buildings, the Carnegie Library (1905) and the St. John's Hotel (1915).

Hunt also designed churches throughout the South. This included well-known Chattanooga churches such as Second Presbyterian Church and First Baptist Church, as well as The Tabernacle in Atlanta. Numerous works by Hunt are preserved and listed on the National Register of Historic Places, 21 of which are covered in one 1979 survey study.

RH

RH, Rh, rH, or rh can stand for:

Roentgen (unit)

The roentgen (R, also röntgen) is a legacy unit of measurement for the exposure of X-rays and gamma rays up to several megaelectronvolts. It is a measure of the ionization produced in air by X-rays or gamma radiation and it is used because air ionization can be measured directly. It is named after the German physicist Wilhelm Röntgen, who discovered X-rays. Originating in 1908, this unit has been redefined and renamed over the years. It was last defined by the US National Institute of Standards and Technology (NIST) in 1998 as 2.58×10⁻⁴C/kg, (i.e. 1 C/kg = 3876 R) with a recommendation that the definition be given in every document where the roentgen is used. One roentgen of air kerma (kinetic energy released per unit mass) deposits 0.00877 grays (0.877 rads) of absorbed dose in dry air, or 0.0096 Gy (0.96 rad) in soft tissue. One roentgen (air kerma) of X-rays may deposit anywhere from 0.01 to 0.04 Gy (1.0 to 4.0 rad) in bone depending on the beam energy. This tissue-dependent conversion from kerma to absorbed dose is called the F-factor in radiotherapy contexts. The conversion depends on the ionizing energy of a reference medium, which is ambiguous in the latest NIST definition. Even where the reference medium is fully defined, the ionizing energy of the calibration and target mediums are often not precisely known.

Rosh Hashanah (tractate)

Rosh Hashanah (Hebrew: ראש השנה‎) is the name of a text of Jewish law originating in the Mishnah which formed the basis of tractates in both the Babylonian Talmud and the Jerusalem Talmud of the same name. It is the eighth tractate of the order Moed. The text contains the most important rules concerning the calendar year, together with a description of the inauguration of the months, laws on the form and use of the shofar and laws related to the religious services during the Jewish holiday of Rosh Hashanah.

Contents

The Mishnah commences with an account of the four beginnings of the religious and the civil year (1:1); it speaks of the four judgement-days of the pilgrim festivals and Rosh ha-Shanah (1:2); of the six months in which the messengers of the Sanhedrin announce the month (1:3); of the two months, the beginnings of which witnesses announce to the Sanhedrin even on the Sabbath (1:4), and even if the moon is visible to every one (1:5); Gamliel even sent on the Sabbath for forty pairs of witnesses from a distance (1:6); when father and son (who as relatives may otherwise not witness together) behold the new moon they must set out for the beth din (1:7), since they do not absolutely belong to those that are legally unfit for this purpose (1:8).

Rosetta@home

Rosetta@home is a distributed computing project for protein structure prediction on the Berkeley Open Infrastructure for Network Computing (BOINC) platform, run by the Baker laboratory at the University of Washington. Rosetta@home aims to predict protein–protein docking and design new proteins with the help of about sixty thousand active volunteered computers processing at over 110 teraFLOPS on average as of November 20, 2015.Foldit, a Rosetta@Home videogame, aims to reach these goals with a crowdsourcing approach. Though much of the project is oriented towards basic research on improving the accuracy and robustness of the proteomics methods, Rosetta@home also does applied research on malaria, Alzheimer's disease and other pathologies.

Like all BOINC projects, Rosetta@home uses idle computer processing resources from volunteers' computers to perform calculations on individual workunits. Completed results are sent to a central project server where they are validated and assimilated into project databases. The project is cross-platform, and runs on a wide variety of hardware configurations. Users can view the progress of their individual protein structure prediction on the Rosetta@home screensaver.

Reach (advertising)

In the application of statistics to advertising and media analysis, reach refers to the total number of different people or households exposed, at least once, to a medium during a given period. Reach should not be confused with the number of people who will actually be exposed to and consume the advertising, though. It is just the number of people who are exposed to the medium and therefore have an opportunity to see or hear the ad or commercial. Reach may be stated either as an absolute number, or as a fraction of a given population (for instance 'TV households', 'men' or 'those aged 25–35').

For any given viewer, they have been "reached" by the work if they have viewed it at all (or a specified amount) during the specified period. Multiple viewings by a single member of the audience in the cited period do not increase reach; however, media people use the term effective reach to describe the quality of exposure. Effective reach and reach are two different measurements for a target audience who receive a given message or ad.

Sarah

Sarah or Sara (/ˈsɛərə/;Hebrew: שָׂרָה, Modern Sara, Tiberian Śārā ISO 259-3 Śarra; Latin: Sara; Arabic: سارا or سارة Sāra;) was the wife and half–sister of Abraham and the mother of Isaac as described in the Hebrew Bible and the Quran. Her name was originally Sarai. According to Genesis 17:15, God changed her name to Sarah as part of a covenant after Hagar bore Abraham his first son, Ishmael.

The Hebrew name Sarah indicates a woman of high rank and is translated as "princess" or "noblewoman".

In the Hebrew Bible

Sarah was the wife of Abraham, as well as being his half-sister, the daughter of his father Terah. Sarah was approximately ten years younger than her husband.

She was considered beautiful to the point that Abraham feared that when they were near more powerful rulers she would be taken away and given to another man. Twice he purposely identified her as being only his sister so that he would be "treated well" for her sake. No reason is given why Sarah remained barren (childless) for a long period of time. She was originally called "Sarai", which is translated "my princess". Later she was called "Sarah", i.e., "princess".
