BNF

Then, HSM domain ontology was described and expressed by Backus -Naur Form (BNF) formulations, and was stored in relationship database.

In BNF , the only way to indicate a list of an arbitrary number of elements is through recursion .

Some reports indicate reduction of legume BNF by mineral N is dependent on host species and form of N available.

As a critical tool, BNF models play irreplaceable roles in predicting nitrogen fixation of soybean quantitatively.

Like rhizobia, the nitrogen-fixing endophyte Frankia elicits the formation of specialized root nodule structures which house BNF processes.

To ensure N available from BNF does not limit legume yield, many farmers inoculate their crops with rhizobia .

The grammars for complex languages are commonly described using BNF (Backus-Naur Form) notation or its close relative, EBNF (Extended BNF).

Generally, increasing mineral N available to legumes reduces N derived from BNF without enhancing yield appreciably.

If you're familiar with parsing, you'll quickly realize that the second argument to the parse function is equivalent to providing a BNF.

Although relative response to N by legume species may differ, N fertilization will reduce nodulation and BNF by legumes.

Recommendations for starter N originate from our knowledge of the legume's physiological dependence on mineral N prior to onset of BNF .

The issue whether starter N will increase nodulation and BNF is, however, complicated by several factors.

the paper adopts bnf to express the logic expressions , providing a good formalization method.

Only when availability of N was increased through effective nodulation and BNF was there a response to applied P.

This section provides basic information on how N affects legume BNF processes and under what conditions legumes respond to mineral N.

Water-rich foods tend to be low in calories or have a low energy density, a BNF conference heard.

The BNF process reduces N2 to plant available forms using bacterial enzymes produced within root nodules.

Based on BNF code, this paper investigates the problems concerning digital processing of rare Chinese characters.

This effect of mineral N assumes there is adequate numbers of effective rhizobia available to the crop to maximize BNF.

Firstly the paper models the simulation scenes scripts of MANET with BNFs and constraints.

Biotechnology Consultation Note to the File BNF No 00077.

Effect of mineral N on legume BNF and yield is a complex issue.

The following table lists BNF lexical rules that describe how to recognize a valid input.

In this way they can ensure adequate N is inexpensively available through BNF.

The characters used for Bayeux names and identifiers are defined by the BNF definitions:

JJTree is a preprocessor, and generating a parser for a particular BNF is an easy two-step process
