An analysis is made of the generation, advection, and dissipation processes of the cirrus canopy in tropical storms with particular emphasis on the formation of sharp edges. Although subsidence and accompanying evaporation may be factors, this formation is closely tied with the wind flow pattern near the edges. The stronger the radial wind velocity in the vicinity of the edges, the greater is t...

The diffusion of ion implanted F in Si has been studied by the use of secondary ion mass spectroscopy and thermal desorption spectroscopy. In the dose range studied (below amorphization threshold), F exhibits an anomalous out-diffusion behavior which is characterized by the depletion of F in Si substrate at temperatures 2550 “C! with complete suppression of diffusion deeper into the bulk of Si....

Fecal bile acid patterns have been used successfully to identify scats. Neotropical felid scats are capable of this biochemical identification because they present low concentrations of plant pigments that would interfere in fecal bile acids detection. However, neotropical felid scats have poor quantities of bile acids, so we developed in this work a proper technique for their extraction, visua...

Georgia Lobbyist, Jet Toney, didn't know what to do. There were 11 days left in the 2020 legislative session and Governor, Lieutenant Speaker of House had decided, due rapid spread COVID-19, suspend a time indeterminate. This never happened, not even wartime. Jet's oldest client, Independent Colleges Association budget item bill they needed handle before Session adjourned. watched all his hard ...

We study the effect of scotogenic dark matter on primordial black holes (PBHs) and vice versa. show that if PBHs evaporate in radiation dominant era, upper limit initial mass $M_{\rm in}$ should be constrained as $10^4 \lesssim M_{\rm in}/M_{\rm Pl} 10^{10}$ for $\mathcal{O}$(1) TeV ($\mathcal{O}$(1) is most appropriate energy scale model). On other hand, PBH dominated a quite heavy ($m_{/rm DM...

In contrast to entropy, which increases monotonically, the “complexity” or “interestingness” of closed systems seems intuitively to increase at first and then decrease as equilibrium is approached. For example, our universe lacked complex structures at the Big Bang and will also lack them after black holes evaporate and particles are dispersed. This paper makes an initial attempt to quantify th...

1,3-Butadiene is a highly volatile gas that is used in the production of synthetic rubber; the major end use of the synthetic rubber is automobile tires. 1,3-Butadiene is also used for the production of high impact polystyrene and acrylonitrile-butadiene-styrene (ABS) resin plastics The predominant source of 1,3-butadiene in the atmosphere is industrial releases, which can occur during manufact...

The extra-solar planet HD209458b has been found to have an extended atmosphere of escaping atomic hydrogen (Vidal-Madjar et al. 2003), suggesting that “hot Jupiters” closer to their parent stars could evaporate. Here we estimate the atmospheric escape (so called evaporation rate) from hot Jupiters and their corresponding life time against evaporation. The calculated evaporation rate of HD209458...

A novel, patented topping power cycle is described that takes its energy from a very high-temperature heat source and in which the temperature of the heat sink is still high enough to operate another, conventional power cycle. The top temperature heat source is used to evaporate a low saturation pressure liquid, which serves as the driving fluid for compressing the secondary fluid in an ejector...

Linear quadratic gaussian (LQG) optimal control techniques can control linear multivariable systems that are precisely known [1,2]. Within the framework of the design, they achieve a best possible performance. However, if the plant is imprecisely known, actual performance can be intolerably poor. The guaranteed gain and phase margins for the case of the nominal plant may evaporate in the presen...
