Weller ULI NG. The Weller ULI NG (New Generation), sometimes called the Weller Uli NG, is a German ultralight aircraft, designed and produced by Weller Flugzeugbau of Bibersfeld. It was introduced at the Aero show held in Friedrichshafen in 2010. The aircraft is supplied as a complete ready-to-fly-aircraft.

Design and development
The aircraft is derived from the Egon Scheibe Uli 1 and was re-designed to comply with the German  class ultralight rules. It features a cable-braced high-wing, a single-seat open cockpit without a windshield, fixed conventional landing gear and a single engine in pusher configuration.

The aircraft fuselage is made from welded steel tubing, the wing built from bolted-together aluminum tubing, with its flying surfaces covered in aircraft fabric. Its  span wing has an area of , giving a very light wing loading of 17.0 kg/m2 (3.5 lb/sq ft). The standard engine available is the  Briggs & Stratton industrial four-stroke powerplant with a V-belt reduction drive, powering a two bladed wooden propeller. The engine burns  per hour at cruise. The aircraft's  fuel tank is detachable for refueling and is filled with premium auto-fuel. The design incorporates a ballistic parachute whole-aircraft rescue system that includes an ignition cut-off upon firing.

Mobile Emergency Alert System. The Mobile Emergency Alert System (M-EAS) is an information distribution system that utilizes existing digital television spectrum and towers to provide information in emergency situations using rich media.  The system can push text, web pages, and video to compatible equipment, such as mobile DTV devices.  M-EAS is different than existing 90-character Wireless Emergency Alerts (WEA) available to cellphones, as it allows video, audio, photos and graphics, too.

Proponents of the technology point to modern reliance on mobile communication technologies and failures of the cellular network due to overload, power outage or other emergency-related damage. M-EAS does not rely on the network of cellular towers, instead making use of existing digital television broadcast equipment.

M-EAS is being standardized by the Advanced Television Systems Committee as part of ATSC-M/H, the mobile digital TV standard. WRAL-TV in Raleigh, North Carolina, was the first commercial broadcaster in the United States to demonstrate the system in 2012.

A similar system in Japan is credited with saving many lives ahead of the 2011 Tōhoku earthquake and tsunami.

Vevey–Montreux–Chillon–Villeneuve tramway. The Vevey–Montreux–Chillon–Villeneuve tramway (VMCV) was a metre gauge electric tramway in the Swiss canton of Vaud. It linked the towns of Vevey, Montreux and Villeneuve close to the shoreline of Lake Geneva, and also served the famous Château de Chillon. The line was formed by a merger of the Vevey–Montreux–Chillon tramway (VMC) and the Chillon–Byron–Villeneuve tramway (CBV).

Vevey–Montreux–Chillon
The Vevey–Montreux–Chillon tramway was opened in 1888, and was the first electric tramway in Switzerland. It used an early electrification method, with twin overhead copper tubes carrying both polarities. The current was collected by a trolley running on these tubes, and pulled by the tramcar. The cars were double-deck, with an open upper deck.

Chillon–Byron–Villeneuve
The Chillon–Byron–Villeneuve tramway, effectively an extension of the earlier line but under separate ownership, opened in 1903. It used what had, by then, become the standard tram electrification method of a single overhead cable, with current return via the running rails. The two lines were merged to form the Vevey–Montreux–Chillon–Villeneuve tramway in 1913. The earlier line was rebuilt to use the later electrification method.

Technical details
The merged line was single-track and street-running throughout, and was electrified at 600 V DC. It had a length of , with 62 stops, a maximum gradient of 5% and a minimum radius of . It shared a common section, of just  in length, with the Clarens–Chailly–Blonay tramway (CCB) in the Montreux suburb of Clarens.

Closing and legacy
The tramway closed in 1958, and was replaced by the Vevey–Villeneuve trolleybus line. The owning company survived, and is now, under the name VMCV SA, the principal bus and trolleybus operator in the Vevey and Montreux area.

Advanced fire information system. The advanced fire information system (AFIS) provides information on current and historical fires detected by sensors on Earth observation satellites, e.g. NASA MODIS, EUMETSAT MSG, GOES, NPP, etc. covering multiple regions across the globe. The system provides monitoring of active fire on a web-based map and delivers near real-time alerts to registered users when a fire is detected within their specified areas of interest via email, SMS, XMPP, etc.

The system started as a research project at the CSIR Meraka Institute in collaboration with Eskom in 2007. It was then extended to support many fire protection associations in South Africa.

Woolmer Lecture. The Woolmer lecture is the flagship lecture of the Institute of Physics and Engineering in Medicine. It takes place annually during the Institute's Medical Physics and Engineering Conference.

Dedication 
The lecture is dedicated to Professor Ronald Woolmer (1908–1962) who was the first Director of the Research Department of Anaesthetics at the Royal College of Surgeons. Woolmer convened a meeting at the Royal College of Surgeons, London, to discuss the evolving field of engineering applied to medicine. It was agreed that the group should hold regular meetings and as a result the Biological Engineering Society (BES) was formed with Ronald Woolmer as the first President. Woolmer died two years after the formation of the BES and it was agreed that a memorial lecture would be sponsored in recognition of his achievements.

Ewald Kienle. Ewald Kienle (21 December 1928 – 1 February 2021) was a German inventor and entrepreneur. He developed and produced electronic church organs.

Early life and work 
Born in Nußdorf nearby Ludwigsburg (today a part of Eberdingen), Kienle is the son of a village blacksmith and the village blacksmith's Sicilian wife. At the age of 15, he was summoned from school to go work for the aircraft manufacturer Messerschmitt, learning aircraft construction. After World War II in 1945, he concentrated on improving and repairing radio and the first television sets. Eventually, he began to develop his own church organs.

Organ innovations 
By 1970, Kienle was producing his own analogue church organs (the Kienle T-Model). They were so well constructed that even the Physikalisch-Technische Bundesanstalt (Federal Institute of Physics and Technology) validated it had a lively sound. Simultaneously, Kienle started to experiment with resonator tubes to improve the sound quality of the loudspeaker. In 1980, he installed the first analogue church organ with resonators in St. Rochus Catholic Church in Bonn-Duisdorf.

From 1980 onwards, Kienle developed digital church organs. In Europe, the first digital church organ (Model Kienle PK II), was installed in the European Parliament in Strasbourg in 1985 and was inaugurated with a Bach concert.

By 1990, Kienle had started research on the use of original organ pipes without core as resonators (pipe resonators) which he installed, partly with additional resonator tubes, in the Kienle Resonator System for all kinds of digital organs.

Kienle held several patents as of 1970, the earliest ones in the field of analogue organs. His later inventions allowed the technically complex airflow stimulation of organ pipes to be replaced by simpler loudspeaker sound stimulation with more frequencies at the same time. In addition to the sound innovations, this reduced manufacturing costs to about one-third of the costs of a traditionally built pipe organ. With the elimination of the high maintenance costs for pipe organs, which are prone to temperature and humidity fluctuations, smaller parishes were able to purchase and maintain an organ.

During an approximately 50-year period, Kienle installed more than 3,000 organs worldwide: in Europe, South Africa, Peru, and Russia. In 2010, the largest organ with the Kienle Resonator System was installed in the concert hall of the newly built Tbilisi Centre in Tbilisi, Georgia.

Due to old age, Kienle closed down his retail company, Ewald Kienle e.K., in 2011. His life's work is continued by the newly founded KIENLE® Orgeln GmbH.

Pitsea waste management site. Pitsea waste management site is a large landfill site on the north side of the Thames estuary  from Pitsea in Basildon, Essex. It is the second largest landfill site in the UK operated by Veolia Ltd. receiving 800,000 tonnes of solid waste per year, mostly from the London conurbation.

The decomposition of organic matter within the landfill generates a gas rich which is rich in methane. This landfill gas is collected by a network of pipes and since 2001 has been used to power generators producing 16.2 MW of electricity. The electricity is sent into the National Grid; this amounts to about 94.4 GWh per year sufficient to power 14,300 homes.

After the site closes in the early 2020s, the Royal Society for the Protection of Birds plans to convert it to a nature reserve.

Hydraulic debarker. A hydraulic debarker is a machine removing bark from wooden logs by the use of water under a pressure of  or greater.  Hydraulic debarking can reduce soil and rock content of bark, but may increase the water content.  Debarking water may be recycled after effective settling, but suspended solids may increase wear on high-pressure pumps.  Hydraulic debarking has declined where water quality problems have arisen.

History
Bark on mature redwood trees of coastal California can vary from  in thickness. Redwood bark is thick, stringy and tough; and can cause sawmill machinery to malfunction. Men called peelers removed bark from fallen trees in the woods through the early 20th century, but the process was dangerous and labor intensive. In the mid-20th century hydraulic barkers were built at several large sawmills including the Union Lumber Company at Fort Bragg, California, the Northern Redwood Company at Korbel, and the Pacific Lumber Company at Scotia, California.  The last was featured in a popular sawmill tour.

Operation
Although less expensive mechanical debarkers were adequate for smaller logs harvested from young trees on redwood tree farms, hydraulic barkers remained in operation until all old growth trees had been harvested from company timberlands.  The United States Environmental Protection Agency published hydraulic barking category effluent limitations in the 1970s.  Wastewater discharged from debarking could average no more than 2.5 pounds of biochemical oxygen demand (BOD) and 12 pounds of total suspended solids (TSS) per thousand board feet of lumber produced (0.5 kg BOD and 2.3 kg TSS per cubic meter of lumber).  Daily waste discharge rates could be three times as high as 30-day averages, but pH was required to remain between 6 and 9.

Railway workshop. Railway workshops are railway facilities in which rolling stock is repaired. While often colocated with engine sheds to perform routine tasks as well as major repairs, in some countries separated concepts exist with railway workshops being specialized in major repairs and general inspections.

In German-speaking countries, the generic names Werkstatt, or specifically in Austria Hauptwerkstatt, are commonly used, except for Germany, where railway workshops maintained by Deutsche Bahn are called Ausbesserungswerk or simply Werk.
