Improved Propagation and Growing Techniques for Oleander Nursery Production

open access: yesHorticulturae, 2019
In the first trial, we examined rooting of stem cuttings in relation to number of nodes and indole-3-butyric acid (IBA) treatment in several Nerium oleander clones grown in Sicily.

Aerosol modeling over Europe: 2. Interannual variability of aerosol shortwave direct radiative forcing

open access: yes, 2007
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.

A Model in Which Well-Orderings of the Reals First Appear at a Given Projective Level, Part III—The Case of Second-Order PA

open access: yesMathematics, 2023
A model of set theory ZFC is defined in our recent research, in which, for a given n≥3, (An) there exists a good lightface Δn1 well-ordering of the reals, but (Bn) no well-orderings of the reals (not necessarily good) exist in the previous class Δn−11 ...

The Forcing Domination Number of Hamiltonian Cubic Graphs [PDF]

open access: yes, 2009

A Generic Model in Which the Russell-Nontypical Sets Satisfy ZFC Strictly between HOD and the Universe

open access: yesMathematics, 2022
The notion of ordinal definability and the related notions of ordinal definable sets (class OD) and hereditarily ordinal definable sets (class HOD) belong to the key concepts of modern set theory. Recent studies have discovered more general types of sets,

Linear non-normal energy amplification of harmonic and stochastic forcing in turbulent channel flow [PDF]

open access: yes, 2010
The linear response to stochastic and optimal harmonic forcing of small coherent perturbations to the turbulent channel mean flow is computed for Reynolds numbers ranging from Re_tau=500 to Re_tau=20000.

A Model in Which Well-Orderings of the Reals First Appear at a Given Projective Level, Part II

open access: yesMathematics, 2023
We consider the problem of the existence of well-orderings of the reals, definable at a certain level of the projective hierarchy. This research is motivated by the modern development of descriptive set theory.
