Dichloroacetaldehyde. Dichloroacetaldehyde is a chlorinated aldehyde with the chemical formula . Along with monochloroacetaldehyde and trichloroacetaldehyde, it is one of the three possible chlorinated acetaldehydes.

Properties and reactions
Dichloroacetaldehyde is a highly volatile liquid that is easily soluble in water to form Hydrates. A geminal diol, also known as monohydrate, 2,2-dichloro-1,1-ethanediol, is formed in water. 

The compound decomposes when heated. In the presence of Lewis acids such as antimony trichloride, iron(III) chloride, aluminum trichloride, tin(IV) chloride or boron trifluoride, the trimer hexachloroparaldehyde (2,4,6-tris(dichloromethyl)-1,3,5-trioxane) can be obtained. The trimer forms colourless crystals that melt at 131–132 °C. At the boiling point of 210–220 °C, dichloroacetaldehyde decomposes.

Reduction with lithium aluminium hydride gives dichloroethanol.

Uses
Dichloroacetaldehyde is used to produce other chemical compounds such as mitotane. Condensation with chlorobenzene yields p,p′-dichloro-1,1-diphenyl-2,2-dichloroethane, which was previously used as an insecticide:

Synthesis
Dichloroacetaldehyde can be obtained by chlorinating acetaldehyde or paraldehyde. Hypochlorination of 1,2-dichloroethylene using chlorine and water produces pure dichloroacetaldehyde.

FRET (software). Formal Requirements Elicitation Tool (FRET) is a requirements engineering tool. It was developed by the NASA Ames Research Center to specify complex safety-critical systems whose failure could result in loss of life, significant property damage, or environmental harm. FRET is open-source software released under the NASA Open Source Agreement.

Background 
The behavior and features of a system are specified by its requirements. Most requirements are written in natural languages such as English, which is easy for analysts and stakeholders to understand but cannot be checked for errors and omissions using formal methods. On the other hand, formal notations such as VDM and Z, which are precise and unambiguous, tend to be difficult for analysts and stakeholders to understand.

As a compromise, FRET requirements are created in a controlled natural language called FRETish and converted into temporal logic.

Uses 
FRETish requirements can correspond to variables in external code or models. FRET generates and verifies formal equivalents for each statement, allowing requirements to be imported or exported in a variety of formats including JSON.

In FRET, processes are simulated and analyzed by interfacing with external modeling and analysis tools. The supported external tools include COCO simulator, Simulink Design, Verifier, NuSMV, and Copilot.

Adras (fabric). Adras is a natural handmade fabric that consists of 50 percent silk fibers and 50 percent cotton. Adras is traditionally woven in Uzbekistan and Tajikistan. In Uzbekistan, this fabric is also called “Podshohi” (royal), indicating its exceptional value associated with an elaborate and costly manufacturing process as well as a rich and sophisticated appearance. Adras is characterized by its strength, rich colors and the possibility of using it for a long period of time without losing its properties.

The practice of making atlas and adras in traditional ways by the Margilan Craft Center was inscribed on the UNESCO List of Intangible Cultural Heritage of Humanity in 2017.

History 
In Central Asia (Bukhara, Samarkand, Khujand, Namangan, Margilan), the production of silk and semi-silk fabrics reached a special development in the 19th - early 20th centuries. In modern history, a festival of Adras and Atlas takes place in Tajikistan. In Uzbekistan, the “Silk and Spices” festival is held every two years in Bukhara, where Adras is also presented.

Description 
Adras is softer than pure silk and is therefore often used to make clothing, accessories, bedding and home textiles. The fabrics are often decorated with Uzbek ornaments, which have long been a national heritage and part of the region's culture. Natural plant seeds are used by craftsmen to dye the fibers. For example, the Uzbek ornament consists of rich, noble and natural shades.

Adras is made by hand and has a width of 32 to 55 cm, as a larger width is not possible on looms. In Bukhara, the fabric has its own gisar abrob pattern with the motif “Doiragul, Kuzagul” - a small pot. The pattern of the Adra is arranged in three longitudinal rows. The main colors of the patterns are red and yellow on a white background. Oval-shaped drawings are filled with purple, yellow and blue lines. There are yellow ovals in the middle of the burgundy jugs.
