A twystron is a type of microwave-producing vacuum tube most commonly found in high-power radar systems. The name refers to its construction, which combines a traveling wave tube, or TWT, with a klystron, producing a tw-ystron. The name was originally a trademark of Varian Associates, its developer, and was often capitalized. In recent times has become a generic term for any similar design.

The twystron amplifies a source signal using a conventional klystron, which consists of a series of cylindrical resonant chambers fed with the source signal. An electron gun at one end of the tube produces electrons that flow through holes in the centers of the resonators. As they pass through the holes, the signal within the resonator causes the electrons to "bunch up", a process known as velocity-modulation. The resulting electron beam is an amplified version of the original signal. In a conventional klystron, this signal is then captured and used as the output. 

In the twystron, the output instead flows into a TWT for further amplification. The advantage of this approach is that while the multi-resonator klystron is an efficient amplifier, its bandwidth is reduced as one adds additional resonators, which makes high-power klystrons have a relatively low bandwidth generally less than 10% of the design frequency. In contrast, the TWT has a wider bandwidth response but are generally very long. By combining a klystron with a TWT, the result is a relatively compact device with improved bandwidth; typical twystrons have bandwidth up to 15% of the design point.

The device was developed by Albert La Rue and Rodney Rubert in the early 1960s and was quickly adopted by many radar designs in order to improve frequency agility and thereby improve performance against radar jamming systems. The twystron was generally replaced by the extended interaction klystron and solid state amplifiers.

The FRP Pedestrian Bridge or  in Lleida, Spain is the longest arch bridge made out of standard GFRP pultruded profiles.

The bridge spanning the Madrid-Barcelona high-speed rail link won the international “Footbridge Award 2005” in the category “Technology” for medium span (30m-75m) bridges.

Description
The structure is a tied-arch  long and rises . The deck is  wide. The bridge is entirely made out of GFRP pultruded profiles. The arch configuration was chosen so as to minimize serviceability problems due to the low modulus of elasticity of GFRP profiles. The choice of GFRP was influenced by the fact that the material is an electrical insulator and eliminates magnetic interference with the electrified railway.

The glass fibre reinforced plastic beams and panels used in the footbridge were manufactured in Denmark and assembled in Spain. The total cost of the structure was approximately $0.32million ($2350 per m2).

It was successfully installed in October 2001. The bridge was fabricated in only three months and erected by crane in just three hours.

Cotula australis is a species of plant in the daisy family known by the common names bachelor's buttons, annual buttonweed, southern waterbuttons and Australian waterbuttons. This small plant is native to Australia and New Zealand, but it is known in other areas of the world as a common weed (South America, California, Mexico, South Africa, etc.).

Cotula australis grows low to the ground in a thin mat with some slightly erect, spindly stems. The leaves are divided and subdivided into fringelike lobes. The plant flowers in inflorescences only a few millimetres wide containing minuscule yellow disc florets surrounded by greenish brown bracts and rudimentary ray florets that have been reduced to pistils with no stamens or corolla. The fruit is a tiny winged achene about a millimetre wide.

The EFLU Hyderabad well (also known as Maha Laqa Chanda Bai's well) is a cultural heritage of English and Foreign Languages University (EFLU) in Hyderabad, Telangana in India. It was built during the Asaf Jahi period and is around 200 years old. It is a large stepped well and the geometrical design is distinct amidst a variety of historical architecture from the Nizam period. It is a three-storeyed structure which has five flight of steps, two on each storey and one that leads to the water. This well is in the shape of a square with four arches on each floor and is also a square on plan at the bottom.

The heritage well was enlisted in the state heritage list by the Hyderabad Metropolitan Development Corporation (HMDC) and Municipal Corporation (MC) in January, 2013. The EFLU Heritage Well Conservation Committee from EFLU Hyderabad is the responsible body for planning, conserving and promoting this cultural heritage. In 2013 students petitioned the country's President to call for the well to be preserved.

Doris Williams Stadium is a multi-use stadium in Grand Bassa County, Buchanan, Liberia.  It is currently used mostly for football matches on club level by Mighty Barrolle of the Liberian Premier League. The stadium has a capacity of 3,000 spectators.

Renovation

In July 2012, funds of $538,482,000 were approved by Grand Bassa County administration to begin renovations on the Doris Williams Stadium. The county had plans to expand to 6,000 seats, build an administrative building, ticket and security booths, reinforced concrete bleachers, two VIP seated areas, parking lots, and fund landscaping.

The county had paid the contractor, CJ Construction Inc., 75% of the total cost, with an initial payment of $161,544.60. CJ Construction renovated an existing fence, gates, and some toilets. However, 100% of the construction had not been finished by the appropriate deadline, prompting an investigation.

The failure of the contractors to deliver prompted community leaders, sports players, and social justice groups to speak out about the failures of CJ Construction to adhere to the agreement.

James Johnson, head of CJ Construction, cited a change in county leadership in 2013 as the reason for the failure to complete the work, saying that the government successors never followed up on the construction project.

In 2014, the Bassanonian community and local leaders again expressed public concern and frustration for the appearance of the stadium and had urged the Grand Bossa County administration to renovate and "beautify" the stadium.

Future Renovation Plans

The FIFA Regional Development Office proposed the addition of new turf to Doris Williams Stadium in the spring of 2019.

The Russian Orthodox Church in Uzbekistan is the main community of Eastern Orthodox Christianity in Uzbekistan, a mainly Muslim country. Many of its members are Russians. Uzbekistan falls within the area of Tashkent and Central Asian Eparchy of the Russian Orthodox Church. The Eparchy is headed by a Metropolitan. Since 2011, the current Metropolitan of Tashkent and Central Asia is Vincent (Morar).

Russian Orthodox Church in Uzbekistan has been established in 1871 and extends to Tajikistan, Turkmenistan and Kyrgyzstan. The Russian Orthodox Church has a better standing with the government than other religious groups do. The constitution establishes a secular framework to separate church and state.

Government figures in 2020 suggested that 2.2% of the population of Uzbekistan are Orthodox Christians, most of whom are ethnic Russians.
