It details Manning's background, the evolution of his monomial formula from its inception to its widespread acceptance among practitioners, and the subsequent advancements in hydraulic resistance formulas that address the limitations of Manning's work.

Despite the emergence of more sophisticated theories and equations, Manning's formula remains prevalent in practical applications, highlighting a paradox between its simplicity and the advanced understanding of fluid mechanics.

Cognitive-behavioral treatment of a person with generalized anxiety disorder A case of a year-old woman who asked help by the presence of panic attacks is reported. After assessment, it was considered that the main problem was the presence of excessive and persistent anxiety and worries. Forty-three sessions of cognitive-behavioral treatment were conducted, two with her husband.

Panic attacks were addressed with psychoeducation, training in controlled breathing and cognitive restructuring, whereas the excessive worries were addressed with stimulus control, cognitive restructuring, training in problem solving, behavioral experiments and imaginal exposure. Patient's reports and scores. We review the current state of knowledge concerning microbial extremophiles and comets and the potential significance of comets to Astrobiology.

The transfer of incident energy from sunlight into the interior leads to the melting of near surface ices, some under stable porous crust, providing possible habitats for a wide range of microorganisms. We provide data concerning new evidence for indigenous microfossils in CI meteorites, which may be the remains of extinct cometary cores.

He compared and evaluated seven best known formulas of the time: Du Buat , Eyelwein , Weisbach , St.

He calculated the velocity obtained from each formula for a given slope and for hydraulic radius varying from 0. Then, for each condition, he found the mean value of the seven velocities and developed a formula that best fitted the data. This formula saw the light in , in a paper written by him entitled "On the flow of water in open channels and pipes," published in the Transactions of the Institution of Civil Engineers Ireland.

In the United States, n is referred to as Manning's friction factor, or Manning's constant. In , he became district engineer, a position he held until From to , Manning was employed by the Marquis of Downshire, while he supervised the construction of the Dundrum Bay Harbour in Ireland and designed a water supply system for Belfast. He became chief engineer himself in , a position he held it until his retirement in In he was awarded the Telford Medal by the Institution of Civil Engineers for his paper " On… the flow of water off the ground in the Woodburn District near Carrickfergus ".

He had married his second cousin Susanna Gibson in , by whom he had seven surviving children, one of whom, William Manning, was also an engineer. His second daughter was the painter Mary Ruth Manning Manning did not receive any education or formal training in fluid mechanics or engineering. His accounting background and pragmatism influenced his work and drove him to reduce problems to their simplest form.

He compared and evaluated seven best known formulae of the time for the flow of water in a channel: Du Buat , Eyelwein , Weisbach , St.
