Robert Loftus Owen Versfeld

Robert Loftus Owen Versfeld[2] (7 December 1862 - 5 May 1932) was a South Africa rugby union player and administrator who was a founder member of the Eastern Province Rugby Union and of the Pretoria Rugby Subunion (1908) which in 1938 became Northern Transvaal. He founded Pretoria Rugby Club (1888)[3] and established Pretoria rugby headquarters at Eastern Sports Grounds. He introduced grass playing fields to the Transvaal.[4]


He is the only South African player to have won a Grand Challenge Cup in three different provinces with three different teams: the inaugural Western Province Grand Challenge Cup with Hamilton Rugby Football Club (1883); the Eastern Province Grand Challenge Cup with Union RFC (1888); and the Transvaal Grand Challenge Cup with Pretoria RFC (1889). Versfeld played for a Transvaal Country XV against W.E. McLagan's touring British side in 1891.[4]

Sekhemre Khutawy Sobekhotep is well attested by contemporary sources. First, he is mentioned on the Kahun Papyrus IV, now in thePetrie Museum (UC32166).[1] (Ryholt, p.315)[4][5] This Kahun Papyrus is "a census of the household of a lector-priest that is dated to the first regnal year" of the king and also records the birth of a son of the lector-priest during a 40th regnal year, "which can only refer toAmenemhat III."[6] This establishes that Sekhemre Khutawy Sobekhotep reigned close in time to Amenemhat III. Second, a number of architectural elements bearing Sobekhotep's titulary are known: a fragment of a Hebsed chapel from Medamud, three lintels from Deir el-Bahri and Medamud, an architrave from Luxor and a door jamb from Medamud that is now in the Louvre. Three Nile level records fromSemna and Kumna in Nubia are also attributable to Sekhemre Khutawy Sobekhotep, the latest of which is dated to year 4, showing that he reigned for at least three complete years.[1][7] Smaller artifacts mentioning Sekhemre Khutawy Sobekhotep comprise a cylinder seal from Gebelein, an adze-blade, a statuette from Kerma and a faience bead, now in the Petrie Museum (UC 13202).[1][4][8] Finally, the tomb of Sekhemre Khutawy Sobekhotep was discovered in Abydos in 2013 and attributed to him in 2014 from a stele fragment bearing hiscartouche.

Wikipedia! Roxy Ann Peak is a 3,576-foot-tall (1,090 m) mountain in the Western Cascade Range in the U.S. state of Oregon. Composed of several geologic layers, the majority of the peak is of volcanic origin and dates to the early Oligocene. It is primarily covered by oak savanna and opengrassland on its lower slopes, and mixed coniferous forest on its upper slopes and summit. Despite the peak's relatively small topographic prominence of 753 feet (230 m), it rises 2,200 feet (670 m) above Medford, and it is the city's most important viewshedopen space reserve, and recreational resource. Roxy Ann Peak was originally settled 8,000 to 10,000 years ago by ancestors of the native Latgawa tribe. In the early 1850s, a sudden influx of non-indigenous settlers led to the Rogue River Wars. After the wars, the Latgawa were forced away from the region onto reservations. The peak was named in the late 1850s after one of its first landowners, Roxy Ann Bowen. In 1937, the 1,740-acre (704.2 ha) Prescott Park was created on the peak's upper slopes and summit from land donated by the Lions Club and the federal government, and the park is largely undevelop

Wikipedia: A waveguide filter is an electronic filter that is constructed with waveguide technology. Waveguides are hollow metal tubes inside which an electromagnetic wave may be transmitted. Filters are devices used to allow signals at some frequencies to pass (the passband), while others are rejected (the stopband). Filters are a basic component of electronic engineering designs and have numerous applications. These include selection of signals and limitation of noise. Waveguide filters are most useful in the microwave band of frequencies, where they are a convenient size and have low loss. Examples of microwave filter use are found in satellite communicationstelephone networks, and television broadcasting.
Waveguide filters were developed during World War II to meet the needs of radar and electronic countermeasures, but afterwards soon found civilian applications such as use in microwave links. Much of post-war development was concerned with reducing the bulk and weight of these filters, first by using new analysis techniques that led to elimination of unnecessary components, then by innovations such as dual-mode cavities and novel materials such as ceramic resonators.
A particular feature of waveguide filter design concerns the mode of transmission. Systems based on pairs of conducting wires and similar technologies have only one mode of transmission. In waveguide systems, any number of modes are possible. This can be both a disadvantage, as spurious modes frequently cause problems, and an advantage, as a dual-mode design can be much smaller than the equivalent waveguide single mode design. The chief advantages of waveguide filters over other technologies are their ability to handle high power and their low loss. The chief disadvantages are their bulk and cost when compared with technologies such as microstrip filters.
There is a wide array of different types of waveguide filters. Many of them consist of a chain of coupled resonators of some kind that can be modelled as a ladder network of LC circuits. One of the most common types consists of a number of coupled resonant cavities. Even within this type, there are many subtypes, mostly differentiated by the means of coupling. These coupling types include apertures,[w] irises,[x] and posts. Other waveguide filter types include dielectric resonator filters, insert filters, finline filters, corrugated-waveguide filters, and stub filters. A number of waveguide components have filter theory applied to their design, but their purpose is something other than to filter signals. Such devices include impedance matching components,directional couplers, and diplexers. These devices frequently take on the form of a filter, at least in part.
Brr it's cold.
Here's my first test entry. Welcome to my blog?

Yeah, yeah, I'ma up at Brooklyn, now I'm down in Tribeca
Right next to De Niro, but I'll be hood forever
I'm the new Sinatra, and since I made it here
I can make it anywhere, yeah, they love me everywhere
Right there up on Broadway, brought me back to that McDonald's
Took it to my stash spot, 560 State Street
Catch me in the Kitchen like a Simmons whipping pastry

I used to cop in Harlem, all of my Dominicanos
