B. P., female, aged 14 years, admitted to the Worcester Eye Hospital on February 28, 1952, for operation to overcome congenital inaction of the right external rectus. There was no movement of the right eye beyond the mid-line when looking right but 5A right hyperphoria was produced by the attempt. In the primary position there was no hyperphoria. Spectacles were worn for slight convergent strab...

In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...

We consider weak preference orderings over a set An of n alternatives. An individual preference is of refinement ≤ n if it first partitions An into subsets of ‘tied’ alternatives, and then ranks these subsets within a linear ordering. When < n, preferences are coarse. It is shown that, if the refinement of preferences does not exceed , a super majority rule (within non-abstaining voters) with r...
