The Theory of Brown Dwarfs and Extrasolar Giant Planets
Full text linkStraddling the traditional realms of the planets and the stars, objects below
the edge of the main sequence have such unique properties, and are being
discovered in such quantities, that one can rightly claim that a new field at
the interface of planetary science and and astronomy is being born. In this
review, we explore the essential elements of the theory of brown dwarfs and
giant planets, as well as of the new spectroscopic classes L and T. To this
end, we describe their evolution, spectra, atmospheric compositions, chemistry,
physics, and nuclear phases and explain the basic systematics of
substellar-mass objects across three orders of magnitude in both mass and age
and a factor of 30 in effective temperature. Moreover, we discuss the
distinctive features of those extrasolar giant planets that are irradiated by a
central primary, in particular their reflection spectra, albedos, and transits.
Aspects of the latest theory of Jupiter and Saturn are also presented.
Throughout, we highlight the effects of condensates, clouds, molecular
abundances, and molecular/atomic opacities in brown dwarf and giant planet
atmospheres and summarize the resulting spectral diagnostics. Where possible,
the theory is put in its current observational context.Comment: 67 pages (including 36 figures), RMP RevTeX LaTeX, accepted for

Sample analysis of correlation of cost inputs of timber products in roof construction.
No full textTimber is widely used in the construction of buildings. It is a very visible component of
roof structure and it forms the structure upon which the covering is laid. The cost of
roofing is on the increase owing to the difficulties in sourcing timber in lumber forms
nowadays. In Nigeria the construction of roof for residential buildings mostly in bungalows
depend much on timber. A sample of thirty units of cost of timber roof structure from three
(3) bedrooms flat under construction was collected from Contractors and Developers.
Correlation was used to find out the cost input of timber in roof vs. the total cost of roof,
the critical value of r =.195, cost input of roof in the total cost of building, r =.090, as well
as cost input of timber in roof on the total cost of building, result shows r =-.063. Weak
strength of relationship for the first two cases and negative was seen in the last case
