On Entire and Meromorphic Functions That Share One Small Function with Their Differential Polynomial

open access: yes, 2013
We study the uniqueness of meromorphic functions that share one small function with more general differential polynomial . As corollaries, we obtain results which answer open questions posed by Yu (2003).

Value Distribution and Arbitrary-Order Derivatives of Meromorphic Solutions of Complex Linear Differential Equations in the Unit Disc

open access: yesMathematics, 2019
In this paper, we investigate the value distribution of meromorphic solutions and their arbitrary-order derivatives of the complex linear differential equation f ′ ′ + A ( z ) f ′ + B ( z ) f = F ( z ) in Δ

Induction and synchronization of oestrus in sheep and goats [PDF]

open access: yesJournal of Central European Agriculture, 2021
Different methods for oestrus induction and synchronization in domestic small ruminants have been developed. Seasonality and female’s status are important factors for choosing the most appropriate treatment. In the case of females during breeding season,

The transfer functions of rocket nozzles [PDF]

open access: yes, 1952
The transfer function is defined as the fractional oscillating mass flow rate divided by the fractional sinusoidal pressure oscillation in the rocket combustion chamber. This is calculated as a function of the frequency of oscillation.

On the probability distribution function of small scale interplanetary magnetic field fluctuations [PDF]

open access: yes, 2004
In spite of a large number of papers dedicated to study MHD turbulence in the solar wind there are still some simple questions which have never been sufficiently addressed like: a)do we really know how the magnetic field vector orientation fluctuates in ...
