The Queen’s Torture and The Winter’s Tale

The further exploration is carried out to have a deeper understanding of King Leontes and his jealousy and violence. Autolycus, the rogue, is given a detailed avaluation so as to reveal his active role in the play and the artistic flavour on the stage. The brave and straight forward lady Paulina is held in high regard because of both of her brilliant words and benevolent actions. The fourth Act of the play is regarded as the excellent part of the play based on its rich and colourful picture of the rural life by the playwright Shakespeare. Since Hermione, the heroine, is the main character of all the main characters, and the fate of hers is the focus of the whole play, so the title of this play is in need of change.     

The Characteristic Polynomial of the Mixed Arrangement

We consider the mixed arrangement which is com posed of the central hyperplane arrangement and a sphere. We discuss the lattice of its intersection set and the relationship between the Mbius function of the mixed arrangement and the original hyperplane arangement. The Mbius function of the mixed arrangement is equal to the positive or the negative Mbius function of original hyperplane arrangement. Moreover, we give an equality of the chambers and the characteristic polynomial for the mixed arrangement.

The evolution model of the earth’s limited expanding

Based on the prerequisite that the earliest acid rock formed because of the initial global expanding tectonic processes, by combining it with other geological limitation conditions, and starting from the lithosphere elastic mechanics, the following is defined: the earth expansion started at about 4300 Ma ago, the average increasing rate of the earth radius is 0.40 mm/a, the initial expanding earth radius is 4651 km, and the initial global expansion of tectonic processes happened at 4183.7 Ma ago. From the natural and attenuation evolution condition of the earth and terrestrial planets, through the limit condition got from the combination of the mathematics logic and the geological significance, the limited expanding earth evolution model is established as follows: in whichR ₀= 4.651×10⁶ m,A =1.86×10⁶ m, β = -6.01×10⁻¹⁰/ a andt _s=3×10⁸ a. From this model the maximum radiusR _maxof the limited expanding earth evolution should be 6511 km. The earth’s radius increasing rate is about 0.1 mm/a at present.

The complexity of the Latin Square task and its influence on children’s performance

Prior studies analyzed the complexity of the Latin Square task solely based on the relational complexity theory, which, with the relational complexity defined by the complexity of relations processed in paral-lel, could not fully predict children’s performance on the task. So we developed an alternative method to analyze the task complexity by the relational complexity and the necessary processing steps to find a solution. The present study tested the validity of the new method applying to the Latin Square ...
