Bis(triphenylphosphine)rhodium carbonyl chloride. Bis(triphenylphosphine)rhodium carbonyl chloride is the organorhodium complex with the formula [RhCl(CO)(PPh3)2].  This complex of rhodium(I) is a bright yellow, air-stable solid.  It is the Rh analogue of Vaska's complex, the corresponding iridium complex.  With regards to its structure, the complex is square planar with mutually trans triphenylphosphine (PPh3) ligands.  The complex is a versatile homogeneous catalyst.

Synthesis and reactions
Bis(triphenylphosphine)rhodium carbonyl chloride was originally prepared by treating Rh2Cl2(CO)4 with triphenylphosphine.  However, it is typically produced by the carbonylation of Wilkinson's catalyst:
RhCl[P(C6H5)3]3  +  CO  →   RhCl(CO)[P(C6H5)3]2  +  P(C6H5)3
In homogeneous catalysis, this conversion is typically an undesirable side-reaction since [RhCl(CO)(PPh3)2] is a poor hydrogenation catalyst.

Bis(triphenylphosphine)rhodium carbonyl chloride is the precursor to tris(triphenylphosphine)rhodium carbonyl hydride, an important catalyst for hydroformylation.
RhCl(CO)[P(C6H5)3]2  +  NaBH4 +  P(C6H5)3  →   RhH(CO)[P(C6H5)3]3  +  NaCl  +  BH3

Wilcox P. Overbeck. Wilcox Pratt Overbeck (1912–1980) was an electrical and nuclear engineer who built instrumentation for the first nuclear reactor, the Chicago Pile-1, and went on to work at other United States Department of Energy national laboratories.  He previously worked with Vannevar Bush at MIT on the Rapid Arithmetic Machine.  

A one-hot ring counter is sometimes referred to as an "Overbeck ring"; he patented such a device made with a multi-anode vacuum tube in 1943.  At the Met Lab in Chicago, he used such counters to scale the rate of detected ionization events, to estimate the rate of the nuclear reaction in the Chicago Pile-1, Enrico Fermi's famous first critical nuclear reactor.

Loop sectioning. In geometry and the mathematical discipline of topology, loop strip-mining, or sectioning, is a special case of tiling, namely 1-dimensional tiling: a loop is transformed into a depth-2 loop nest, where the outer loop is called tile/block loop and the innermost loop is called element loop.
Strip-mining was introduced for vector processors. It is a loop-transformation technique for enabling vectorization of loops and improving memory performance.

The term strip-mine is really inspired from mining coal, for example, with the excavator, which uses a bucket (or bucket wheel) to "strip" the coal.

Explorer 24. Explorer 24 (also called AD-B, Air Density experiment-B and S-56C) was a NASA satellite designed for atmospheric studies. Explorer 24 was launched on 21 November 1964 from Vandenberg Air Force Base, Lompoc, California, with a Scout X-4. Explorer 24 was launched along with its successor satellite, Explorer 25.

Spacecraft 
Explorer 24 was placed in orbit together with Explorer 25 from a single launch vehicle. Explorer 24 was identical in configuration to the previously launched balloon satellites Explorer 9 and Explorer 19. The spacecraft was  in diameter, was built of alternating layers of aluminum foil and plastic film, and was covered uniformly with  white dots for thermal control. It was designed to yield atmospheric density near perigee as a function of space and time from sequential observations of the sphere's position in orbit. To facilitate ground tracking, the satellite carried a 136-MHz tracking beacon.

Experiments

Nonsystematic Changes of Air Density 
This experiment was designed to determine nonsystematic changes of the density of the upper atmosphere from studies of the drag on a  diameter low-density sphere caused by short-term differences in solar activity. Density values near perigee were deduced from sequential observations of the spacecraft position, using optical (Baker-Nunn camera network) and radio and/or radar tracking techniques. This experiment resulted in the successful determination of reasonable density values until spacecraft re-entry.

Systematic Changes of Air Density 
This experiment was designed to determine systematic changes of air density as a function of altitude, latitude, and time of day, by measuring the drag on a  diameter low-density sphere with ground tracking.

Results 
Explorer 24 helped determine the variation in density between the day and night of the Earth and gave rise to studies on the zone winds in the exosphere, at an altitude of between  and .

The satellite reentered the Earth's atmosphere on 18 October 1968.

Hygroreception. Hygroreception is the ability to detect changes in the moisture and humidity content of an environment. It is a sense that is not present in humans. Many insects have this sense which has been studied using the cockroach and stick insect. The structure responsible for this sense is a hygroreceptor. In a study conducted upon nematodes, both thermal and mechanical neural pathways are required in order for a specimen to react to humidity. This supports the theory that hygroreception is a result of thermal and mechanical stimuli.

B&R rig. The B&R rig is a variant of the Bermuda sailboat rig, designed and patented by Swedish aeronautical engineers Lars Bergström and Sven Ridder. It employs swept spreaders that are usually angled aft, together with "stays" running diagonally downward from the tip of the spreaders to the attachment of the next pair of spreaders to the mast or to the intersection of the mast with the deck (so-called reverse-diagonal shrouds) that facilitates a pre-bend of the mast (curving aft) that is sometimes tuned into the rig before it is stepped onto the boat. Conventional shrouds thereby contribute to both lateral and longitudinal stability, unlike rigs with unswept spreaders. A B&R rig can be a masthead or fractional rig depending on how stays are configured; a backstay is optional. Such rigs are employed in many of the models of at least one U.S. manufacturer and in many thousands of boats, worldwide.



History 
The earliest B&R rig was the result of wind tunnel tests and research by Lars Bergstrom and Sven Ridder at Sweden's Royal Institute of Technology.  The first generation, built around 1970, included a backstay and was used on many production boats. A patent application for the B&R rig was submitted in 1973 and was granted in 1975. A second generation eliminated the backstay but used solid, deck-mounted struts to brace the lower mast section.  In 1982 a second generation B&R rig with 2 forestays was incorporated into the  "breakthrough" racing yacht Thursday's Child. On February 13, 1989 Thursday's Child beat the 135 year old clipper ship record sailing  from New York to San Francisco. A third generation B&R rig mounted the mast on a tripod of struts, had a single forestay and no backstay. In 1993 the third generation was incorporated into the all carbon/kevlar  yacht Route 66. The  yacht Hunter's Child finished 2nd in the 1994-95 BOC Challenge using a second generation B&R rig. By 1997 more than 10,000 production sailboats were using the B&R rig.

Tuning 
Part of the design of the B&R rig involves inducing a "pre-bend" in the mast which provides some of the side-to-side and fore-and-aft stability of the rig. The pre-bend is achieved by tensioning the reverse diagonals and certain other so called intermediate shrouds. Because the spreaders are swept back at approximately a 25° to 30° angle, this tensioning bows the mast. Balanced and proper tensioning keeps the bow and the mast aligned in the fore-aft direction and eliminates any curvature in the sideways direction. The pre-bend is generally set up on the ground before the mast is stepped (placed onto the boat). The mast is then stepped and all other standing rigging is attached to the boat and properly tensioned.

Boat and yacht models incorporating B&R rigs 
The majority of Hunter Marine's fleet incorporated the B&R rig. However, manufacturers on both sides of the Atlantic Ocean have employed B&R rigs in their boat designs.

Don Embankment. Don Embankment () in Rostov-on-Don is situated on the right side of the river.

History 
In the 1860s in Rostov was formed a street called Beregovaya (Coastal Street) which soon began to be intensively built up. Because of frequent fires, in 1873 the City Duma prohibited building wooden houses there. It was allowed to build only brick buildings with a roof made of iron.

The narrow Beregovaya Street eventually had expanded to the shore, where an embankment was built by 1881.

In 1834 the first construction project of Rostov-on-Don Embankment was proposed by military engineer Lieutenant-Colonel Shmelyov, but this project wasn't completed. In 1842, another draft by Captain Baron Firks was proposed, according to which the embankment was to be extended to 924 meters. Yet again no construction works had been carried out then. In the years 1895–1905, a cargo embankment was built in the city with a pier, running water and electricity lighting. It had huge stone buildings of grain barns, warehouses, customs house, stock exchanges for fish trade and so on. There were steamship piers of passenger and cargo traffic, grain warehouses. So far, five buildings, known as the Paramonov Warehouses, which have the status of a monument of history and culture of federal significance.

Already in Soviet times, in 1944, architect Vladimir Sokolov proposed a project of reconstruction of the embankment, which was implemented. The railway tracks and warehouses were removed from the embankment, and the cranes were moved upstream along the Don. The embankment began to turn into a recreation area. Boulevards and flower gardens were opened there. Works on the improvement of the embankment were conducted under the guidance of the architects Valentin Razumovsky and Jan Rebayn. The opening of the reconstructed Rostov Embankment took place on 7 August 1949.

In 2010s several sculptures and monuments were installed at the embankment. Every year it also hosts the Don River Festival, which is visited by approximately ten thousand people.
