Estimation of period and Q of the Chandler wobble [PDF]
SUMMARY The period P and Q-value of the Chandler wobble are two fundamental functionals of the Earth's internal physical properties and global geodynamics. We revisit the problem of the estimation of P and Q, using 10.8 yr of modern polar motion as well as contemporary atmospheric angular momentum (AAM) data.

Chandler Wobble and Free Core Nutation: Theory and Features
Being a torque free motion of the rotating Earth, Chandler wobble is the major component in the Earth’s polar motion with amplitude about 0.05-0.2 arcsec and period about 430-435 days.

A preliminary nonlinear analysis of the earth's chandler wobble
The Chandler wobble (CW) is a resonant response of the Earth rotational pole wandering around its figure axis whose excitation mechanism is still uncertain.

Earth’s rotation irregularities derived from UTIBLI by method of multi-composing of ordinates [PDF]
Using the method of multi-composing of ordinates we have identified in Earth’s rotation a long-periodic term with a period similar to the relaxation time of Chandler nutation. There was not enough information to assess its origin. We demonstrate that the

Optimizing Seed Germination and Growth of Seedlings in Persian Walnut [PDF]
The efficiency of conventional stratification methods for seed germination of walnut (Juglans regia L.), which uses long moist-chilling periods, is low. This experiment was conducted during winter to spring 2014 to optimize the seed germination of walnut

The period and Q of the Chandler wobble [PDF]
The calculation of the theoretical period of the Chandler wobble is extended to account for the non-hydrostatic portion of the earth's equatorial bulge and the effect of the fluid core upon the lengthening of the period due to the pole tide. The theoretical period of a realistic perfectly elastic earth with an equilibrium pole tide is found to be 426.7

Phenological and production characteristics of some strawberry varieties in the region of Skopje [PDF]
Phenological and production characteristics have been observed on 17 strawberry varieties. The earliest flowering was observed in Honeoye and Eris (5 April). The latest flowering variety is Onda (13 April).

Is the Chandler period variable? [PDF]
Summary. This paper investigates whether the Chandler period is variable in time. The first step is to develop an Instantaneous Frequency Analysis to trace the time-varying spectrum for a non-stationary , complex-valued time series. The method is then applied to the observed polar motion to find no significant fluctuation of the Chandler period.
