most nonoates are stable in alkaline solution above ph 8.0 (e. g. 10 mm naoh) and can be stored at −20 °c in this way for the short term. to generate no from nonoates, the ph is lowered accordingly. typically, a dilution of the stock nonoate solution is made in a phosphate buffer (ph 7.4; tris buffers can also be used) and incubated at room temperature for the desired time to allow no to accumulate in solution. this is often visible as bubbles at high nonoate concentrations. incubation time is important, since the different nonoates have different half-lives ("t") in phosphate buffer at ph 7.4. for example, the half-life of mahma nonoate under these conditions is ~3.5 minutes, whilst the "t" of dpta nonoate is 300 minutes. this is often useful in biological systems, where a combination of different nonoates can be used to give a sustained release of nitric oxide. at ph 5.0, most nonoates are considered to decompose almost instantaneously.

united nations regional groups









































the united nations regional groups are the geopolitical regional groups of member states of the united nations. originally, un member states were unofficially grouped into five geopolitical regional groups. what began as an informal means of sharing the distribution of posts for general assembly committees has taken on a much more expansive role. many un bodies are allocated on the basis of geographical representation. top leadership positions, including secretary-general and president of the general assembly, are rotated among the regional groups. the groups also coordinate substantive policy and form common fronts for negotiations and bloc voting.
