With Hydrogen sulphide ( H2S ) at a level of 1 ppm, a victim will barely notice a bad smell, at 30 + ppm H2S smells like rotten eggs but at 50-100 ppm it smells cloyingly sweet.

NETL ’ s research and development efforts contribute to the following vital national goals: ( 1 ) Secure and reliable energy supplies ; ( 2 ) Clean power production ; ( 3 ) Climate change ; ( 4 ) Hydrogen economy ; etc ..

Hydrogen uptake ( H < sub > 2 </ sub > oxidation ) ( 1 ) is coupled to the reduction of electron acceptors such as oxygen, nitrate, sulfate, carbon dioxide, and fumarate, whereas proton reduction ( H < sub > 2 </ sub > evolution ) ( 2 ) is essential in pyruvate fermentation and in the disposal of excess electrons.

Hydrogen ( H ) ( Standard atomic mass: 1. 00782504 ( 7 ) u ) has three naturally occurring isotopes, sometimes denoted < sup > 1 </ sup > H, < sup > 2 </ sup > H, and < sup > 3 </ sup > H.

And if the foreigners fighting in the Katanga Army are mercenaries then Lafayette and Von Steuben were mercenaries too, as were also the members of the Lafayette Escadrille in the early part of World War 1, and of Chennault's Flying Tigers in the early days of World War 2.

The reasons are obvious: ( 1 ) the state is buying in quantity, and ( 2 ) it has no federal excise or state sales tax to pay.

Taxation of tangible movable property in Rhode Island has been generally of a `` hands off '' nature due possibly to several reasons: ( 1 ) local assessors, in the main, are not well paid and have inadequate office staffs, ( 2 ) the numerous categories of this component of personal property make locating extremely difficult, and ( 3 ) the inexperience of the majority of assessors in evaluating this type of property.

Among the many problems in the taxing of personal property, and of movable tangible property in particular, two are significant: ( 1 ) situs, ( 2 ) fair and equitable assessment of value.

In order to assist the States in maintaining basic vocational rehabilitation services, Section 2 of the amended Act provides that allotments to States for support of such services be based on ( 1 ) need, as measured by a State's population, and ( 2 ) fiscal capacity, as measured by its per capita income.

This claim, as submitted to the District Court and dismissed by it, 126 F.Supp.235, alleged violation not only of 7 of the Clayton Act, but also of 1 and 2 of the Sherman Act.

He claims that he was denied due process of law in violation of the Fifth Amendment, because ( 1 ) at a hearing before a hearing officer of the Department of Justice, he was not permitted to rebut statements attributed to him by the local board, and ( 2 ) at the trial, he was denied the right to have the hearing officer's report and the original report of the Federal Bureau of Investigation as to his claim.

In the event the total of rupees accruing to the Government of the United States of America as a consequence of sales made pursuant to this Agreement is different from the rupee equivalent of $1,276 million, the amounts available for the purposes specified in paragraph 1, Article 2, will be adjusted proportionately.

These were physically identical to those used by the Acorn Electron ' Plus 1 ' interface, but with enhanced electrical characteristics for some of the cartridge connector pins ( See " Appendix 7, The Master 128 Cartridge Interface "-" Advanced Reference Manual for the BBC Master ").

For the coherent quantum 1 / f effect, see the Physica Status Solidi paper of 1996, the Transactions in Electron Devices paper of 1994, and the Proceedings of IEEE paper with graduate student Adam Tournier of 2005, all shown in the above mentioned quantum 1 / f bibliography.

Hence in contrast to other Electron Energy Loss Spectroscopies ( EELS ) HREELS deals with small energy losses in the range of 10 < sup >− 3 </ sup > eV to 1 eV.
