Applied Mechanics, 2022 The question addressed is whether the free oscillations of a continuous system can be suppressed, or at least the total energy reduced, by applying external forces, using as example the linear undamped transverse oscillations of a uniform elastic string.

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

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 ...

Studies for using frameless plastic in the forcing of some ornamental crops
International Journal of Horticultural Science, 2000 On the basis of a six-year experiment a method was elaborated for forcing and off-seasons growing of tulips, narcissus and gladioli under frameless plastic cover.

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,

On the Countering of Free Vibrations by Forcing: Part II—Damped Oscillations and Decaying Forcing
Applied Mechanics, 2023 The present two-part paper concerns the active vibration suppression for the simplest damped continuous system, namely the transverse oscillations of an elastic string, with constant tension and mass density per unit length and friction force ...
