Boris (EP)

Boris is the original EP recorded by Yezda Urfa to gather attention from record companies. Three of the pieces were reworked on Sacred Baboon (To-Ta in the Moya, Boris and his 3 Verses (including "Flow Guides Aren't My Bag"), and 3, Almost 4, 6 Yea). The album is now a rare find in the progressive rock circles

Limiting reagent

The limiting reagent (or limiting reactant) in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities required to react with the limiting reagent, they are described as excess reagents or excess reactants.

The limiting reagent must be identified in order to calculate the percentage yield of a reaction, since the theoretical yield is defined as the amount of product obtained when the limiting reagent reacts completely. Given the balanced chemical equation, which describes the reaction, there are several equivalent ways to identify the limiting reagent and evaluate the excess quantities of other reagents.

Method 1: Comparison of reactant amounts

This method is most useful when there are only two reactants. One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent. If the amount of B present is less than required, then B is the limiting reagent.

Excess-3

Excess-3 or 3-Excessbinary code (often abbreviated as XS-3 or X3) or Stibitz code (after George Stibitz) is a complementary BCD code and numeral system. It also constitutes a biased representation. Excess-3 was used on some older computers as well as in cash registers and hand held portable electronic calculators of the 1970s, among other uses. It is a way to represent values with a balanced number of positive and negative numbers using a pre-specified number N as a biasing value. It is a nonweighted code. In XS-3, numbers are represented as decimal digits, and each digit is represented by four bits as the digit value plus 3 (the "excess" amount):

To encode a number such as 127, then, one simply encodes each of the decimal digits as above, giving (0100, 0101, 1010).

Adding Excess-3 works on a different algorithm than non-biased decimal coding or regular binary positional system numbers. When you add two XS-3 numbers together, the result is not an XS-3 number. For instance, when you add 1 and 0 in XS-3 the answer seems to be 4 instead of 1. In order to correct this problem, when you are finished adding each digit, you have to remove the extra bias by subtracting binary 0011 (decimal 3 in unbiased binary) if the resulting digit is less than decimal 10 and subtracting binary 1101 (decimal 13 in unbiased binary), if an overflow has occurred. Note that, in 4-bit binary, subtracting binary 1101 is equivalent to adding 0011 and vice versa.
