Combat Search and Rescue (Turkish Armed Forces). The Combat Search and Rescue () or by its official name Personnel Rescue () is a combat search and rescue and advanced air controller unit affiliated to the Turkish Air Force whose task is to recover pilots and other military personnel stranded behind enemy lines and qualified service member who directs the action of combat aircraft engaged in close air support and other offensive air operations from a forward position. It is similar to the United States Air Force Pararescue unit. Between 2017 and 2021, it was also known as 'Search and Rescue Specialized Personnel' (). It is selected from among the officers and non-commissioned officers of the Turkish Air Force who are highly talented and who have passed various elimination stages. They serve as squadrons in accordance with the air base commands where they are located. They receive 53 weeks of training.

The activities first started in 1953. Between 1970 and 1990, UH-1H and C-47 were included in the inventory and used. Squadrons began to be established in 1995. In 2003, the name of the Search and Rescue Survival course command was changed to Combat Search and Rescue School Command. In addition to the duties of Military Search and Rescue (CSAR) and Target Designation (JTAC), the unit, which is also in communication with the Search and Rescue Coordination Center, participates in civilian search and rescue activities when needed. In 2006, they carried out the rescue operation of the pilot who crashed into the Aegean Sea as a result of the collision of Turkish and Greek F-16 aircraft. They participated in Operation Olive Branch.

The trainings given are:

 Summer and winter mountaineering, Skiing
 Military parachute free jumping
 Frogman
 Escape and rescue
 Survival
 Target marking, Dynamic-Time sensitive targeting
 Air support in populated areas
 High altitude jump
 Air infiltration
 Launching boats into the sea
 Sea rescue.

Personnel who complete the training are accepted to the team. Teams are trained to stay in the field for long periods with 30-pound weapons, ammunition and equipment. The physical adequacy of the teams is evaluated every year. Personnel who fail the exam are removed from the team.

They conduct JTAC training with Special Forces Command teams in the international Anka exercise held every year.

Oswalds mill audio. Oswalds Mill Audio (OMA) is an American lifestyle company that designs and manufactures high end audio equipment for the home. OMA was founded in 2007, in New Tripoli, Pennsylvania by the filmmaker Jonathan Weiss. In addition to horn loudspeakers, OMA also manufactures amplifiers, turntables, tonearms, and accessories.

Overview 
Oswalds Mill Audio is well known in the audio industry for their incorporation of vintage sound technologies in their product designs, such as the rare conical horn profile and field coil drivers. OMA is the only high end audio company manufacturing conical profile horn loudspeakers today. OMA developed out of the infamous “Oswalds Mill Tube and Speaker Tasting”, a yearly event held in the 18th-century mill owned by Weiss in New Tripoli, PA. The first OMA loudspeaker was commissioned by the photographer and filmmaker Anton Corbijn. OMA is directly inspired and influenced by the horn-loaded loudspeaker designs pioneered by RCA in the 1930s and 1940s.

In 2014, OMA released the world’s first cast-iron speaker, the Ironic, with each speaker weighing 400lbs. The Ironic is cast with 3-D printed molds and made from hypo eutectic high graphite grey iron. OMA is known in the audio world for their unique approach to sound and design. Due to the use of conical horns, their speakers are much larger than those using curved horns or typical enclosed loudspeakers. The largest speaker OMA manufactures is called the Imperia, a four-way conical horn system measuring 7′ (2.1 m) tall.

Seth Baum. Seth Baum is an American researcher involved in the field of risk research. He is the executive director of the Global Catastrophic Risk Institute (GCRI), a think tank focused on existential risk. He is also affiliated with the Blue Marble Space Institute of Science and the Columbia University Center for Research on Environmental Decisions.

Academic career 
Baum obtained his BS in optics and mathematics in 2003 at the University of Rochester, followed by an MS in Electrical Engineering, Northeastern University in 2006.

In 2012, he obtained his PhD in Geography with his dissertation on climate change policy: "Discounting Across Space and Time in Climate Change Assessment" from Pennsylvania State University. Later, he completed a post-doctoral fellowship with the Columbia University Center for Research on Environmental Decisions. Baum then steered his research interests into astrophysics and global risks, including global warming and nuclear war, and the development of effective solutions for reducing them.

Furthermore, he is a Fellow of the Society for Risk Analysis.

Work 
As a graduate student in Northstrom, Boston, Baum contributed to the Whats Up magazine (now Spare Change News), from 2004 to 2007.

In 2011, Baum co-founded GCRI along with Tony Barrett, with the mission to "develop the best ways to confront humanity's gravest threats". The institute has since grown rapidly, publishing in peer-reviewed academic journals and media outlets. As of 2016, its main work is on the "Integrated Assessment Project", which assesses all the global catastrophic risks in order to make them available for societal learning and decision making processes. GCRI is funded by "a mix of grants, private donations, and occasional consulting work.

Two years later, Baum hosted a regular blog on Scientific American and has been interviewed about his work and research in the History Channel and the O'Reilly Factor., where he was asked about studying possible human contact with extraterrestrial life and the ethics involved. He also started contributing regularly to The Huffington Post, writing about the Russo-Ukrainian War and the Syrian Civil War as possible scenarios for nuclear war.

In 2016, after receiving a 100,000 dollar grant from the Future of Life Institute his research interests shifted to AI safety and the ethics of outer space. That same year, he wrote a monthly column for the Bulletin of the Atomic Scientists, where he discussed AI threats, biological weapons and the risks of nuclear deterrence failure.

Zanzibar Electricity Corporation. Zanzibar Electricity Corporation is a state owned utility firm that provides transmission and distribution service of electricity in the Zanzibar Archipelago. The firm was incorporated in 2006 as the successor of the State Fuel and Power Corporation and is wholly owned by the Revolutionary Government of Zanzibar.

History

Background

Electricity in Zanzibar 
Electricity in Zanzibar dates back to the early 1870s. In 1875, the first coal fired generator was installed on the island to power Stone Town. In 1954 the coal plants were abandoned and new diesel generators were installed by the British East Africa Company. In 1980 the main island of Unguja was connected to the Tanzanian National Grid via a 132kV, 45MW sub-marine cable and the diesel generators were decommissioned.

Electricity in Pemba 
The first power plant on the island of Pemba was commissioned in 1958 and was called the Tibirinzi power station. Over the years the government continued to build small diesel generators to meet the growing demand. However, in 1985 the government replaced the Tibirinzi power station and inaugurated the Wesha Power station. The power station had three diesel generators with a total capacity of 4.5 MW. Pemba was also connected to the national grid through a submarine cable from Pangani. The 33kV, 20 MW cable runs from Pangani, to Tanga to Ras Mkumbuu.

Corporate affairs

Ownership 
The corporation is 100% wholly owned by the Revolutionary Government of Zanzibar, under the umbrella of the Ministry of Land, Housing, Water and Energy of Zanzibar. The Union government or mainland government do not have any ownership or executive control in the company. The company is controlled by a board of directors directly appointed by the ministry.

Demanufacturing. Demanufacturing is a process where a product after extensive usage, often at the end of its lifespan, is then disassembled or dismantled into its components. Demanufacturing is also commonly referred to as the reverse process of manufacturing and, hence, can next to disassembly or dismantling also include various other processing steps. For example, demanufacturing commonly starts with product manipulation and next a classification step to evaluate the functionality of the product and/or the herein contained components to assess if these are suitable for reuse or are deemed unusable and need to be recycled, so the materials can be used in new products. Demanufacturing was proposed to be used in all industries as a means reduce the environmental footprint while preserving economic viability of the processes involved. This term was first coined by Professor Walter W. Olson and Professor John W. Sutherland in 1993.

In the case of waste electronics demanufacturing involves dismantling them into their components. After a classification and product manipulation step, electronics are typically dismantled into their components either to support the reuse of components (HDDs, RAM, CPUs, etc.) or to facilitate increased precious metal (e.g. Au and Ag of printed wiring boards) and critical metal recovery (e.g. Nd from permanent magnets in HDDs).

Forms of demanufacturing 
There are two forms of demanufacturing: destructive and non-destructive. Non-destructive demanufacturing incorporates non-destructive disassembly actions or semi-destructive disassembly actions in which only the fasteners are damaged to allow for components to be taken apart and then reused in new products. In contrast Destructive demanufacturing relies on destructive dismantling techniques in which information on the product structure is used to define optimal cutting points, which are used to take the product apart and to separate specific components with a higher yield and concentration in support of material recycling. Destructive demanufacturing is commonly adopted when component reuse is no longer possible due to component failures or technical obsolesce and when destructive dismantling techniques are more cost efficient.

Economic effects 
There are numerous economic effects that come with demanufacturing. The practice provides numerous jobs to people and communities; in addition business opportunities and reduction in environmental impact of component reuse and product remanufacturing is considered to encompass great potential. It has been estimated by the  Office of the Federal Environmental Executive that $100 billion in revenue has been generated from this practice.
