When Cold Radial Migration is Hot: Constraints from Resonant Overlap

Cold Kaons from Hot Fireballs

The E814-collaboration has found a component of very low m t K + mesons with a slope parameter of T 15 MeV. We will present a scenario which explains the observed slope parameter and which allows us to predict the expected slope parameter for kaons produced in heavier systems such as Au+Au. Implications for the restoration of chiral symmetry in relativistic heavy ion collisions are discussed.

When You're Hot, You're Hot! Warm-Cold Effects in First Impressions of Persons and Teaching Effectiveness

We examined the effects of Kelley's "warm/cold" manipulation on first impressions of persons and teaching ability. A stimulus person, posing as a visiting professor, gave a "neutral" lecture to 240 university students. Before the stimulus person appeared, half of the subjects received information that he was a rather warm person, whereas the other half was told that he was a rather cold person....

When every $P$-flat ideal is flat

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...

Hot & Cold Working

Q.1. What is hot working ? State its principles, advantages and disadvantages. Ans. Mechanical working of metals above its recrystallisation temperature is known as hot working. Advantages : 1. Larger deformation can be accomplished and more rapidly by hot working since the metal is in plastic state. 2. Porosity of the metal is considerably minimised. 3. Concentrated impurities, if any in the m...
