Cole–Davidson equation. The Cole-Davidson equation is a model used to describe dielectric relaxation in glass-forming liquids. The equation for the complex permittivity is

where  is the permittivity at the high frequency limit,  where  is the static, low frequency permittivity, and  is the characteristic relaxation time of the medium. The exponent  represents the exponent of the decay of the high frequency wing of the imaginary part, .

The Cole–Davidson equation is a generalization of the Debye relaxation keeping the initial increase of the low frequency wing of the imaginary part, . Because this is also a characteristic feature of the Fourier transform of the stretched exponential function it has been considered as an approximation of the latter, although nowadays an approximation by the Havriliak-Negami function or exact numerical calculation may be preferred.

Because the slopes of the peak in  in double-logarithmic representation are different it is considered an asymmetric generalization in contrast to the Cole-Cole equation.

The Cole–Davidson equation is the special case of the Havriliak-Negami relaxation with .

2002 Baltistan earthquakes. In November 2002, two medium-sized earthquakes struck northern Pakistan, causing major damage in Baltistan region and killing 41 people.

Tectonic setting
Pakistan is directly influenced by the ongoing oblique convergence between the Indian Plate and Eurasian Plate. Along the northern margin of the India-Eurasia convergent boundary is the Main Himalayan Thrust which accommodates north–south continental collision. Thrust faulting in the Hindu Kush and Himalaya region is the direct result of the plate interaction. In the Balochistan region, the convergence is highly oblique, involving the large Chaman Fault; a left-lateral strike-slip structure. While a large portion of the boundary is accommodated by strike-slip faulting, the region also hosts the Sulaiman fold and thrust belt. Large thrust earthquakes including the 1934 Nepal–India earthquake were the direct result of the plate interaction. The 2005 Kashmir earthquake occurred near the vicinity of the Main Himalayan Thrust.

Impact
41 people were killed during the two tremors, including a family of seven who all died when their house collapsed, and many others were injured in Diamer District. The number of people rendered homeless was estimated to be about 15,000, and the number of houses damaged was estimated to be 2,756, with a hundred houses destroyed. More than 2,000 people were evacuated from their homes due to the earthquakes. The first tremor killed 17 and injured 65 others, while the second, much stronger earthquake killed 23, including 18 children, with a hundred others injured.

The Karakoram Highway was damaged by landslides which killed hundreds of livestock but soon re-opened for light traffic. Efforts were being made to clear it for heavy traffic but landslides persisted due to the tremors. However one person died and three were injured when an aftershock triggered another landslide on the highway.

Water Tower San Nicolas. Water Tower San Nicolas (Dutch: Watertoren San Nicolas) is a water tower and museum in San Nicolaas, Aruba. It was built in 1939 to relieve the water shortage in Aruba. In 1979, the tower became obsolete and in 1996, it was transferred to the monument fund, and restored. In 2016, the industry museum opened in the tower.

History
The island of Aruba used to depend on rainwater and wells for its drinking water. In 1928, Lago Oil (Exxon) and Shell opened refineries on the island. The population increase resulted in a water shortage which was temporarily relieved by shipments of drinking water from the United States. In 1933, a sea water desalination plant was constructed at Balashi. A distribution network was laid out, and it was decided to build water towers at Oranjestad and San Nicolaas.

In August 1939, the water tower was officially opened by governor Gielliam Wouters. The tower was designed by  and is in Art Deco style. The lower parts were used as offices for the civil service and the water authority. The tower is  tall, and contained a  reservoir located  above the sea water level. In the 1970s, three dry years resulted in the existing plant running close to capacity. In 1979, a larger desalination plant in Balashi was opened, and the water towers were rendered obsolete.

In 1996, ownership of the water tower was transferred to the monument fund who started to restore the building. On 8 March 2013, the tower was restored, and in 2016, the industry museum opened in the building.

Industry museum
The industry museum provides an overview of the industrial activities on Aruba. It has displays of the gold, aloe, phosphate (guano) and oil industries which were present on the island. The public utility companies of Aruba have permanent exhibitions of their activities.

Downfall: The Case Against Boeing. Downfall: The Case Against Boeing is a 2022 American documentary film directed by Rory Kennedy. Interviewing relevant people and featuring archival footage, the documentary looks into the events throughout the history of the aircraft manufacturer company Boeing that led to the crashes of two 737 MAX planes and occurring within a short time span, as well as its subsequent investigation. The film sides with interviewees in criticizing the capitalization of Boeing, noting that the urge to beat major competitor Airbus led to the neglect of component failures within the 737 MAX.

Downfall premiered in a virtual screening at the 2022 Sundance Film Festival on January 21, 2022, before being released on Netflix on February 18 as a Netflix Original Documentary. The film received wide critical acclaim for its comprehensiveness, narrative structure, and emotions, mostly aimed towards Kennedy and editor Don Kleszy. The documentary renewed public attention on the 737 MAX 8 case, causing further criticism of Boeing, who had initially declined to participate in filming and rebuked the film after its release.

Summary
The documentary examines the crashes of two Boeing 737 MAX planes which claimed the lives of 346 people on board and how Boeing may have been more concerned with financial gain over the safety of their passengers.

Kennedy said about the 21st-century history of Boeing:

Release and reception
The film was released on February 18, 2022, and has an 91% approval rating based on 34 reviews on the review aggregator site Rotten Tomatoes, with an average rating of 7.5/10. The site's critical consensus reads: "With impressive clarity, Downfall: The Case Against Boeing reveals corporate corruption that's enraging in its callousness and frightening in its scope."

7.42 million hours were viewed globally on Netflix between February 13, 2022 and February 20, 2022.

Metallwerk Oscar Weil. Metallwerk Oscar Weil is a company with a long tradition from Lahr/Black Forest, known among other things for the brand name abrazo.

History 

The beginnings of the business go back to a hardware and leather goods store founded by two brothers of the Jewish Weil family in Allmannsweier. In 1884, a branch office was established in Lahr. After one of the brothers, Oscar Weil (1860-1926), had recognized the importance of steel shavings, especially for the maintenance of wooden floors, on his travels through Europe, he started the production of this product in 1899 with five workers. By 1901, there were already 12 employees, and by 1914, 30. In 1910, the company also moved into a new factory building in Tramplerstraße. In 1926, the company was taken over by Hugo Weil (1893-1945), Oscar Weil's son, who also produced steel wool from 1931 and built an extension in 1937.

In 1938, the "Aryanization" of the company, which had 150 employees at the time, was initiated and it changed hands at the end of 1939. The new owner was the Baden NSDAP Gauwirtschaftsberater Clemens Kentrup, director at the Tscheulin aluminum plant in Teningen. Kentrup was married to the daughter of Emil Tscheulin. As Nazi economic advisor for Baden, Kentrup was instrumental in promoting the Aryanization of small and medium-sized businesses, which then had to be confirmed by the president of the Chamber of Industry and Commerce. At that time, Kentrup's father-in-law Emil Tscheulin was the president of the responsible Chamber of Industry and Commerce, who presumably also financed Kentrup's takeover of the Oscar Weil metal works.

Hugo Weil emigrated to England and died there in January 1945. In the same year, Iselore Prinz (* 1919-2014), Hugo Weil's daughter, took over the management of the company, which had returned to family ownership, initially with 25 employees, and managed it until 1970. The company continued to innovate, filing patents.

In 1955, the company already had 100 employees. The metal plant is still family-owned and is one of the leading companies in the field of steel chips, steel wool and similar products.

1988 Darbang rockslide. At 11:00 p.m. on 20 September 1988, a huge rockslide occurred in the Darbang region of Nepal. The landslide killed 109 people and buried all the houses in the right bank of the river. The volume of landslide was estimated to be about 5 million cubic meters with a dimension of about 750m high ranging from the elevation of 1750 to 1000 m and width of 500m.  The debris dammed the  Myagdi river for three hours. The debris was gradually eroded by the river without causing flooding in the downstream region.

The cause of slide is not known clearly because there was no rainfall in the area during the landslide period or any earthquake. However, about a month earlier, an earthquake of 6.7 Richter scale had occurred in eastern Nepal. About 62 years earlier, a similar landslide killed about 500 people in the same region.
