Stronger Spring Phenological Advance in Future Warming Scenarios for Temperate Species With a Lower Chilling Sensitivity

Frontiers in Plant Science, 2022
Spring warming could induce earlier leaf-out or flowering of temperate plant species, and decreased chilling in winter has a delaying effect on spring phenology. However, the relative contribution of the decreased chilling and increased forcing on spring

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]

, 2006
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 ...

Effect of Planting Term on Growth and Flowering of Two Cultivars of Lachenalia Produced in A Greenhouse as Potting Plants During Winter Months

Journal of Horticultural Research, 2014
A greenhouse experiment was carried out on lachenalia plants to determine the effect of different bulb planting terms (from October to January) on the growth and flowering of cultivars ‘Ronina’ and ‘Rupert’, in the natural light conditions.

A Model in Which the Separation Principle Holds for a Given Effective Projective Sigma-Class

Axioms, 2022
In this paper, we prove the following: If n≥3, there is a generic extension of L—the constructible universe—in which it is true that the Separation principle holds for both effective (lightface) classes Σn1 and Πn1 of sets of integers.

Forcing companions of Jonsson AP-theories

Қарағанды университетінің хабаршысы. Математика сериясы, 2022
This article is devoted to the study of the forcing companions of the Jonsson AP-theories in the enriched signature. It is proved that the forcing companion of the theory does not change when expanding the theories under consideration, which have some ...

Radiative forcing from aircraft NOx emissions: Mechanisms and seasonal dependence [PDF]

, 2004
A chemistry-climate model has been applied to study the radiative forcings generated by aircraft NOx emissions through changes in ozone and methane. Four numerical experiments, where an extra pulse of aircraft NOx was emitted into the model atmosphere ...

On the Significance of Parameters in the Choice and Collection Schemata in the 2nd Order Peano Arithmetic

Mathematics, 2023
We make use of generalized iterations of the Sacks forcing to define cardinal-preserving generic extensions of the constructible universe L in which the axioms of ZF hold and in addition either (1) the parameter-free countable axiom of choice ACω* fails,

Stochastic forcing of the Lamb–Oseen vortex [PDF]

, 2008
The aim of the present paper is to analyse the dynamics of the Lamb–Oseen vortex when continuously forced by a random excitation. Stochastic forcing is classically used to mimic external perturbations in realistic configurations, such as variations of ...
