Simple and Efficient Parallelization Method for MOC Calculation

Simple and Efficient Method for the Preparation of 5-Bromoisatins

Isatin, N-methyl isatin and N-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (PBC) in acetic acid medium. In the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.

Starting Dose Calculation for Medicinal Plants in Animal Studies; Recommendation of a Simple and Reliable Method

Background and purpose: Research studies indicate that almost 80% of the present day drugs are derived directly or indirectly from medicinal plants. The estimation of a safe starting dose is a concern when a new substance is to be investigated including medicinal plants, in clinical and laboratory studies. This study was intended to explore a simple and reliable method of calcu...

A Simple, Artistic and Efficient Modification of the Inversion Method

     The simplest and fastest way of producing an acceptable and accurate cast is by adopting the two-pour or inversion method. This process is slightly cumbersome and messy due to difficulty of access. A much more efficient, easy and artistic way of accomplishing it is described by adopting a Rotating Cake Icing Table with a Silicone Baking Mat on top as an autoclavable non-stick barrier.    

Generalization of Dodgson's "Virtual Center" Method; an Efficient Method for Determinant Calculation

Charles Dodgson (1866) introduced a method to calculate matrices determinant, in asimple way. The method was highly attractive, however, if the sub-matrix or the mainmatrix determination is divided by zero, it would not provide the correct answer. Thispaper explains the Dodgson method's structure and provides a solution for the problemof "dividing by zero" called "virtua...
