Spanish patrol boat Atalaya. Atalaya (P-74) is a  of the Spanish Navy built in 1991. The ship's primary missions are oceanic patrol, fishing control, escort, and maritime rescue. Its home port is at the La Graña Naval Station in Ferrol.

Description 

Atalaya is an offshore patrol vessel with a displacement of 1,200 tons. It is 68 m (223 ft 1 in) long, has a beam of 10 m (32 ft 10 in), and a draught of 3 m (9 ft 10 in). It is powered by two MTU engines which supply 7,500 horsepower (5,600 kW) to two variable-pitch propellers for a maximum speed of 20 knots. It is equipped with a single 3-inch (76 mm) gun and two 12.7 mm Browning machine guns, and has a crew of 48. Its flight deck can receive medium helicopters.

History 
The ship was built by Navantia in the company's shipyards at Ferrol, and was commissioned by the Spanish Navy on 29 June 1992.

In April 1995, Atalaya was sent to the Northeast Atlantic during the bloodless Turbot War with Canada. It relieved its sister ship Centinela, and remained in the area until it was relieved by the returning Vigía on 6 May 1995. It returned to the area from 13 to 31 June. Atalaya provided maritime security for the 33rd Copa América from 8–10 February 2010.

The ship was involved in an incident on 3 May 2011 off the coast of Gibraltar, when it signaled a merchant ship at anchor to leave Spanish waters. However, Gibraltar maritime authorities instructed the merchant ship to remain at anchor and told Atalaya that Spain did not have jurisdiction over those waters. The British patrol boat HMS Scimitar was dispatched to the area and escorted Atalaya away.

In August 2015, Atalaya intercepted and boarded a sailboat off the Azores Islands and confiscated  of cocaine that was in transit from South America to Galicia.

Silicon Genesis Project. The Silicon Genesis Project is an on-going oral history project on the history of Silicon Valley and the semiconductor industry, conducted by volunteers and housed at the Stanford University Library.

History 
The Silicon Genesis project was started and built upon the inspiration of Rob Walker (1935-2016).  Rob was a Silicon Valley native and Silicon Valley educated electrical engineer, who was involved with the semiconductor industry since the 1960s at Fairchild, Intel and as a founder of LSI Logic. He understood that if the stories of these pioneers were not captured for the benefit of future public access, they would be untold and lost forever. In 1995, Rob began a project with the Silicon Valley Archives in the Stanford University Libraries to record oral history interviews focused on the history of the semiconductor industry. The resulting video recordings and interview transcripts form the basis for the Silicon Genesis collection at Stanford, and available for researchers and others with an interest in this history.

Role of Stanford University 
The Silicon Valley Archives in the Stanford Libraries provides access to several collections related to the Silicon Genesis oral histories. These include the Rob Walker Papers, the Silicon Destiny collection of oral history cassette tapes, videos, and transcripts assembled for Rob Walker's book Silicon Destiny, and the Silicon Genesis collection, which includes physical media for many of the interviews in the series featured in the exhibit.

The collection of interviews

Interviews 
Subjects to be interviewed have been chosen based on their historic contributions to the semiconductor and related industries.   Persons conducting the interviews are former executives of semiconductor companies and have expertise in the fields being discussed.  These individuals have volunteered their time to identify persons of historic interest, scheduled and conducted interviews, assist with post-production, and review transcripts.  Once posted, interviews are available as both streaming video files and lightly edited transcripts.

Interview format 
Prior to 2020, most interviews were typically conducted one-on-one in an informal and comfortable setting, often the home of the interviewee.   More recent interviews have been conducted on the Stanford campus, often the Green Library.  Interviews start with a bit of family and personal history, educational background, and then dive a range of relevant topics relating to the subject's historical contributions to the semiconductor or related industry.

Individual interviews

Group interviews

Panel and special interest videos

Highlighted Collections 
The Stanford Library highlights individual interviews that are grouped together according to an area of interest.  As of January 2025,  there were 18 featured collections from companies, venture capital and industry associations SEMI and the Semiconductor Industry Association.

Sulfluramid. Sulfluramid (N-EtFOSA) is a chemical compound from the group of sulfonic acid amides and per- and polyfluoroalkyl substances (PFASs) that is effective as an insecticide. It acts as an uncoupler (IRAC group 13).

Annual production increased from about 30 tons in 2003 to 60 tons in 2013.

Environmental issues 
It is predominantly biotransformed to perfluorooctanesulfonic acid (PFOS), but partly also to perfluorooctanoic acid (PFOA). Sulfluramid has been banned for almost all insecticidal applications; the only use still allowed by  annex B of the Stockholm Convention on Persistent Organic Pollutants is a bait to control leaf-cutting ants.

2023 Bedford explosion. The 2023 Bedford explosion took place on February 20, 2023 in Bedford, Ohio, US. The explosion occurred at a I. Schumann & Co. copper alloy plant, and caused a large fire and catastrophic damage to the facility and damaged multiple cars in a lot across the street. The explosion was heard by civilians outside of the plant, and by 3:00pm, fire crews from multiple cities were then sent to 22500 block on Alexander Road where the explosion took place. The official address of the building is in Bedford, but it is considered Oakwood Village. According to authorities, 14 people were hospitalized for burn injuries, including a 46 year old factory worker, who later succumbed to them after being admitted in critical condition.

An Occupational Safety and Health Administration investigation found that the company "failed to protect workers from the hazard of steam explosions".

Casualties
According to media outlets, 13 people were hospitalized for injuries, and a 46 year old plant worker, Steve Mullins, was killed.

Waylandite. Waylandite is the phosphate analogue of arsenowaylandite and the aluminum analogue of zaïrite. The mineral was approved by the IMA in 1962, and was published the same year. Waylandite was named in honor of Edgar James Wayland. It is a member of the alunite supergroup, and a member of the plumbogummite – also known as crandallite – group. So far, only two bismuth-bearing members of the alunite supergroup are known, one of which is waylandite, alongside its ferric iron analogue zaïrite.

Properties 
Waylandite forms tiny crystals up to 0.5 mm, but it can also occur as compact fine-grained powder. It can form pseudocubic and pseudohexagonal crystals. It mainly consists of oxygen (38.49%) and bismuth (35.91%), but otherwise contains aluminum (13.91%), phosphorus (10.65%), and a small amount of hydrogen (1.04%). Waylandite does not display any radioactive properties. In its formula, bismuth may be replaced by calcium, and phosphorus may be replaced by silicon. It is often twinned in a cyclic manner, meaning three or more individual crystals are twinned according to the same law but without the twinning planes or axes being parallel. Most minerals of the alunite group have rhombohedral symmetry, of which waylandite is no exception. The arsenate analogue of waylandite supposedly exists, however its description was incomplete. Scharm described it in 1994, and named it arsenowaylandite, however did not submit either the name or the mineral to the International Mineralogical Association.

Synthesis 
Scientists have been able to synthesize waylandite under hydrothermal conditions. The formation of said mineral is confirmed by SEM and IR spectroscopy. The compound forms through the formation of an intermediate crystalline phase and an amorphous phase of composition. The synthesis occurred at 200 °C and 7 MPa. After 6 hours into the process, particles with waylandite's structure, which are morphologically similar to the phase's particles, have been detected. After 12 hours, the formation of the material in amounts that can be distinguished by X-ray diffraction is reached, and after 48 hours, it ends almost completely.

Occurrence 
Waylandite is a secondary mineral which replaces primary bismuth minerals, and as such, it occurs with other bismuth-bearing minerals such as bismutite, bismutotantalite, bismuth, kettnerite, and other minerals in pegmatite cutting quartzite. Waylandite in its crystal form occurs in vugs and rarely in pegmatites; however in its powder form it can be found forming crusts and veinlets. It is the type locality of Wampewo hill, Uganda, but it also occurs in Ngusa and Kobokobo, Congo. In England, it can be found at Wheal Owles, Levant mine, Phoenix mines, Restormel Royal Iron Mine, and in the Gunheath China clay pit. In Germany, it can be found from a dump on the Roter Berg, in Namibia at the Rubicon mine, and in China from an undefined deposit.
