Cyclolysis. Cyclolysis is a process in which a cyclonic circulation weakens and deteriorates. Cyclolysis is the opposite of cyclogenesis.

Extratropical cyclones 

Extratropical cyclones usually undergo cyclolysis after an occluded front forms, which separates the center of the cyclone from the warm air. With the center of the cyclone surrounded by cool air, the temperature difference or baroclinity begins to decline, and the jet stream persisting over the strongest areas of baroclinity which is not over the center of the cyclone, which makes it so that the jet stream is unable to support the system. This usually causes decay and dissipation of the cyclone. When an extratropical cyclone has completed cyclolysis, it usually is not connected to any weather fronts. Extratropical cyclones in the northern hemisphere tend to undergo cyclolysis over the northeast Atlantic Ocean, northwestern Europe, the Gulf of Alaska, the Pacific Northwest, northeast Canada, central Russia, or the eastern Mediterranean sea. In the southern hemisphere, most extratropical cyclones undergo cyclolysis north of 50°S.

Tropical cyclones 
Tropical cyclones often undergo cyclolysis after making landfall, especially if the land is mountainous as the friction with the terrain is increased. Its supply of warm, moist maritime air is also cut off when it moves over land. However, the brown ocean effect may cause a tropical cyclone to maintain its strength, or even intensify over land. A tropical cyclone may also undergo cyclolysis if it moves over water cooler than  as this will cause it to lose its tropical characteristics and become a remnant low. However, these remnant cyclones may persist for a few more days. Excessive wind shear can also cause cyclolysis as it causes the convection that powers the tropical cyclone to move away from the center.

Mesocyclones 
Mesocyclones are localized storms, approximately  to  in diameter within strong thunderstorms. Thunderstorms containing persistent mesocyclones are supercell thunderstorms. Mesocyclones typically undergo cyclolysis when the gust front of the storm blocks off the updraft. At this point, cyclonic circulation weakens, and tornadic supercells lift off the ground. The thunderstorm begins to dissipate as well.

Edward Hall (New York politician). Edward Hall (January 1, 1852 – July 14, 1914) was an American civil engineer and politician from New York.

Life 
Hall was born on January 1, 1852, in Fort Ann, New York.

After studying civil engineering, Hall moved to Lyon Mountain and worked for Chateaugay Ore and Iron Co. as general manager. He later worked as the active agent in San Domingo for the San Domingo Improvement Co. He was a civil engineer there and helped build and operate a 50-mile long railroad from Puerto to Santiago, leaving when the company ended ties with the country. He also helped build the Delaware and Hudson Railway track between Plattsburgh and Whitehall, worked as assistant engineer in locating and building the state narrow gauge railroad to Dannemora, and laid out and built the Chateaugay road from Dannemora to Saranac Lake.

Hall was town supervisor of Dannemora for ten years and was a member of the 1889 United States Assay Commission. In 1891, he was elected to the New York State Assembly as a Democrat, representing Clinton County. He served in the Assembly in 1892. He later moved to Plattsburgh.

Hall died in Albany City Hospital on July 14, 1914.

Avoid-Shift-Improve. Avoid-Shift-Improve (A-S-I) (German: vermeiden,  verlagern, verbessern) is an approach to environmental sustainability that seeks to increase efficiency by modifying consumer behavior. Though it originated in transportation studies, it has since been used to apply to other ways that consumers use natural resources.

History
Avoid-Shift-Improve (A-S-I) was first developed in Germany in the early 1990s as vermeiden, verlagern, verbessern. The term was first published in a 1994 report by the German Parliament's Enquete Commission.

Method
As denoted by the name, Avoid-Shift-Improve has three avenues. It seeks to modify the behavior of consumers rather than producers to make consumer choices more environmentally sustainable.
Avoid, also called reduce: The consumer chooses to use none of or less of a resource.
Shift, also called maintain: The consumer switches from a less sustainable method of consumption to a more sustainable one. If the more sustainable option is already in use, the consumer maintains its use.
Improve: The consumer increases the resource efficiency of an existing good or service.

In the context of transportation efficiency, "Avoid" could mean consolidating or eliminating vehicle trips; "Shift" could include using a bicycle instead of an automobile; and "Improve" could include trading in a gas-powered personal vehicle for a hybrid or electric one. The three routes are considered hierarchical, with avoiding consumption the most impactful, and thus, most important priority.

Application
Though developed for use in transportation, A-S-I has been applied to other consumer sectors, including food, homes, and energy. Technological and entrepreneurial developments can create more A-S-I opportunities, such as smart thermostats that raise and lower interior temperatures based on human occupancy and activity patterns, or meal kits that can reduce food waste by sending pre-apportioned ingredients.

Iron(II) perchlorate. Iron(II) perchlorate is the inorganic compound with the formula . A green, water-soluble solid, it is produced by the reaction of iron metal with dilute perchloric acid followed by evaporation of the solution:

 

Although the ferrous cation is a reductant and the perchlorate anion is a strong oxidant, in the absence of atmospheric oxygen, dissolved ferrous perchlorate is stable in aqueous solution because the electron transfer between both species  is hindered by severe kinetic limitations. Being a weak Lewis base, the perchlorate anion is a poor ligand for the aqueous   and does not contribute to the electron transfer by favoring the formation of an inner sphere complex giving rise to a possible reorganisation of the activated complex. The resulting high activation energy prohibits a thermodynamically spontaneous  redox reaction (∆Gr < 0).

However, in aqueous solution, and under air, iron(II) perchlorate slowly oxidizes to iron(III) oxyhydroxide.

The hexahydrate consists of discreet hexa-aquo-iron(II) divalent cations and perchlorate anions. It crystallizes with an orthorhombic structure. It has minor phase transitions at 245 and 336 K.

Uses
In organic chemistry, iron(II) perchlorate can be used as a source of ferrous ions for the Fenton oxidation.

Saher System. Saher system is an automated traffic enforcement camera system covering major cities in the Kingdom of Saudi Arabia. The system uses digital cameras network technology connected to the National Information Center of the Ministry of Interior.

The technology used is a network of digital instantaneous speed measurement and multipurpose cameras connected to an electronic repository of car owners data. Upon checking for and finding violations of speed limits, seat belt laws, texting-while-driving, or other traffic laws, the system requests the vehicle owner's information from the database and then issues fines accordingly. Car owners are momentarily notified by text of the fine's type, date and amount.

History
On Friday, April 9, 2010, the General Directorate of Public Security announced the Saher system in a statement published by the Saudi Press Agency, that “the Kingdom will witness, in the coming months, the introduction of advanced global technology, represented in the project of monitoring, controlling and managing traffic automatically named the Saher system". On Monday, April 19, 2010, the first phase of the system began in the capital, Riyadh. In a press conference, Prince Khaled Al-Faisal, Governor of Makkah Al-Mukarramah Region, announced the start of implementing the Saher system in Makkah and Jeddah in early August 2010.
