The primordial universe - L’univers primordial

Chapter
It is noted that T.D.A. and R.P.A. calculations for the negative parity states in doubly-closed shell nuclei with N=Z generally underestimate the splitting between the T=0 and T=1 members of a given multiplet....
Chapter
We report on preliminary calculations of the (h,t) reaction, assuming that the helion picks up a neutron, propagates some distance as an alpha, and then strips a proton. The following qualitative results are e...
Article
The time-dependent Hartree-Fock (TDHF) theory is generalized in order to include the effect of two-body collisions (i.e. the residual interaction). This is achieved by adding a collision integral into the TDHF...
Chapter and Conference Paper
In the Paleozoic Sauerland Mountains there are many vein-type ore bodies and occurrences of “alpidic” (saxonian) age, and related strata-bound, epigenetic ores in the transgressive Mesozoic rocks (Permian, Cre...
Article
The isotopic ratios of Pb have been determined from 33 galena samples collected from a variety of occurrences in the north Eifel and north Sauerland. On the basis of the data presented, it is not possible to d...
Article
It is possible that small droplets of quark matter, larger than ordinary nuclei, exist in nature1. These ‘nuggets’ could be present in the Universe and provide one explanation for the dark matter. This suggestion...
Chapter
There are many indications that the baryonic content of the universe is rather low. The observation of the luminous matter in galaxies leads to a ratio Ωbof the baryon density over the critical density of about 0...
Chapter
The removal of the extended hydrogen envelope surrounding the dense core of preexplosive stars by stellar winds or mass transfer onto a companion star, obviously, has consequences on the optical manifestation ...
Article
Boron nitride has been prepared in the past from classical high temperature reactions and more recently by CVD methods. Few attempts have been made to prepare this important material from pyrolyses of preceram...
Chapter and Conference Paper
Tunable Diode Laser Absorption Spectrometer (TOLAS) have been used throughout many years to expand our knowledge about molecular systems and molecular dynamics. This includes the study on neutral molecules, ra...
Article
The appearance of a supernova in the Large Magellanic Cloud made it possible for the first time to detect the neutrino emission from the explosion of a stellar object. Several groups reported neutrino events, ...
Chapter and Conference Paper
We use a semi-analytical model of supernova light curves that extends Arnett's scheme [1,2] to include the effect of recombination of hydrogen, helium and heavy elements in the expanding ejecta. Introducing in...
Article
Studies of the mixed-metal interface in metal impregnated alumina have indicated the possibility of much metal-metal and metal-substrate interaction. Studies were carried out on NiCu/Al2O3 system which was evalua...
Chapter and Conference Paper
If the unseen matter in our Galaxy is provided by very low-mass star-like objects, we show that the halo infrared luminosity is dominated by 0. 1M ⊙ objects. In this case, the halo IMF must be muc...

This paper explores the consequences of different policy assumptions and the derivation of globally consistent, national low-carbon development pathways for the seven largest greenhouse gas (GHG)–emitting coun...
