Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 and 2000 are assessed for the troposphere and the lower ...

Aerosol modeling over Europe: 2. Interannual variability of aerosol shortwave direct radiative forcing [PDF]
Aerosol distribution over Europe and its direct radiative forcing have been simulated with a regional atmosphere-chemistry model and an off-line radiation transfer model. Primary and secondary organic and inorganic aerosols have been considered.

Understanding the nature of the forces driving the folding of proteins, nucleic acids and the formation of their complexes absolutely requires thermodynamic data, in addition to structural information. In practical terms, this means the use of super-sensitive scanning and titration calorimeters for experimental determination of the heats (enthalpies ...

Observations of diurnal and spatial variability of radiative forcing by equatorial deep convective clouds [PDF]
From geostationary satellite observations of equatorial Africa and the equatorial east Atlantic during May and June 2000 we explore the radiative forcing by deep convective cloud systems in these regions. Deep convective clouds (DCCs) are associated with

Flower bud development of almond cultivars based on three different methods
Flower bud development of fruit trees plays a key role in their climatic adaptation. It is closely related to dormancy release that determines winter frost susceptibility. Detailed characterisation of flower bud development of 25 almond (Prunus amygdalus

A Model in Which Well-Orderings of the Reals Appear at a Given Projective Level
The problem of the existence of analytically definable well-orderings at a given level of the projective hierarchy is considered. This problem is important as a part of the general problem of the study of the projective hierarchy in the ongoing ...

Abstract Over the past 10 years, there has been considerable interest in exploring questions connecting dimension for posets with graph theoretic properties of their cover graphs and order diagrams, especially with the concepts of planarity and treewidth.

The Use of Organic Nano-Supplements of Fertilizer for Lily Forcing Period
Lilium is one of the most important ornamental plants after roses, carnations and chrysanthemum in the world that is requested as potted of cut flowers. It is so important to consider its quality along with its production rate in terms of yield (quantity)
