Killing time:Study sheds light on phages and precision cell destruction
Killing time sheds light precision cell destruction
2017/2/15
Phage therapy, which exploits the ability of certain viruses to infect and replicate within bacteria, shows promise for treating antibiotic-resistant bacterial infections.But the design of such therap...
DESTRUCTION OF INVARIANT CURVES IN THE RESTRICTED CIRCULAR PLANAR THREE-BODY PROBLEM BY USING COMPARISON OF ACTION
INVARIANT CURVES RESTRICTED CIRCULAR PLANAR THREE-BODY PROBLEM
2015/9/25
The classical principle of least action says that orbits of mechanical systems extremize action; an important subclass are those orbits that minimize action. In this paper we utilize this principle al...
Disasters,Death,and Destruction—Making Sense of Recent Calamities
Disasters Death Destruction Recent Calamities
2015/7/23
A disaster happens when an extreme event occurs in the context of societal vulnerability. Nowhere is the meeting of vulnerability and extreme more tangible than where the land meets the sea. This was ...
Mesoporous CuO/CeO2 bimetal oxides: One-pot synthesis, characterization and their application in catalytic destruction of 1,2-dichlorobenzene
Mesoporous CuO/CeO2 One-pot synthesis Catalytic destruction 1,2-Dichlorobenzene
2013/12/12
Mesoporous CuO/CeO2 bimetal oxides were synthesized by a one-pot method using a cationic surfactant CTAB as structure directing agent and Cu(NO3)23H2O, Ce(NO3)6H2O and NaOH as the inorganic precurso...
The University of Queensland scientists warn world's cloud forests are at risk of destruction
climate change habitat destruction

Many of the world's most rare and rich forests, the tropical montane cloud forests, could be all-but obliterated by 2080.
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Resonant Destruction as a Possible Solution to the Cosmological Lithium Problem
Resonant Destruction Possible Solution Cosmological Lithium Problem
2011/1/7
We explore a nuclear physics resolution to the discrepancy between the predicted standard
BBN abundance of 7Li and its observational determination in metal-poor stars. The the-
oretical 7Li abundanc...

Quantum Destruction of Spiral Order in Two Dimensional Frustrated Magnets
Quantum Destruction Spiral Order Two Dimensional Frustrated Magnets
2010/11/25
We study the fate of S = 1/2 spiral ordered two dimensional quantum magnets when disordered
by quantum fluctuations. The topological point defects of the spiral, the Z2 vortices, play a crucial role ...
The role of asymmetric interactions on the effect of habitat destruction in mutualistic networks
asymmetric interactions effect habitat destruction mutualistic networks
2010/11/15
Plant-pollinator mutualistic networks are asymmetric in their interactions: specialist plants are pollinated by generalist animals, while generalist plants are pollinated by a broad involving speciali...
Extreme AGN Feedback and Cool Core Destruction in the X-ray Luminous Galaxy Cluster MACS J1931.8-2634
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We report on a deep, multiwavelength study of the galaxy cluster MACS J1931.8-2634 using Chandra X-ray, Subaru optical, and VLA 1.4 GHz radio data. This cluster (z=0.352) harbors one of the most X-ray...

Effects of the Size of Cosmological N-body Simulations on Physical Quantities– II：Halo Formation and Destruction Rate
Large scale structure of Universe N-body simulations galaxies
2009/5/12
In this study we show how errors due to finite box size
affect formation and the destruction rate for haloes in cosmological N-body
simulations. In an earlier study we gave an analytic prescription ...

eddies collide β plane equation model analytical model
2008/12/16
Since midocean eddies Migrate westward, they eventually reach the western boundaries. It is, therefore, of interest to find out what happens after the eddies collide with the walls. An isopycnic, two-...
