The crowd consequently breaks up into temporary groups ranging in size from two to six, with a half-life for the cluster ranging from three to twenty minutes.

In general, the half-life becomes shorter as atomic number increases, though an " island of stability " may exist for undiscovered isotopes with certain numbers of protons and neutrons.

Naturally occurring with a half-life of 1. 25 years, decays to stable ( 11. 2 %) by electron capture or positron emission, and also to stable ( 88. 8 %) via beta decay.

It also has 35 radioisotopes, of which the longest-lived is < sup > 125 </ sup > Sb with a half-life of 2. 75 years.

The most stable of these is < sup > 124 </ sup > Sb with a half-life of 60. 20 days, which has an application in some neutron sources.

Actinium is found only in traces in uranium ores as the isotope < sup > 227 </ sup > Ac, which decays with a half-life of 21. 772 years, predominantly emitting beta particles.

All of its isotopes are short-lived ; the most stable is astatine-210, with a half-life of 8. 1 hours.

Stable < sup > 79 </ sup > Br exhibits a radioactive isomer, with a half-life of 4. 86 seconds.

However, it decays with a half-life of 330 days to californium-249, which is a strong and hazardous emitter of alpha particles.

They discovered two SF activities, one with a 1-2 ms half-life and one with a 5 s activity.

The benzodiazepines with a longer half-life make detoxification more tolerable, and dangerous alcohol withdrawal effects are less likely to occur.

There are three naturally occurring isotopes, with < sup > 12 </ sup > C and < sup > 13 </ sup > C being stable, while < sup > 14 </ sup > C is radioactive, decaying with a half-life of about 5, 730 years.

19 radioisotopes have been characterized with the most stable being < sup > 50 </ sup > Cr with a half-life of ( more than ) 1. 8 years, and < sup > 51 </ sup > Cr with a half-life of 27. 7 days.

Among the isotopes that do not occur naturally, the most long-lived are < sup > 109 </ sup > Cd with a half-life of 462. 6 days, and < sup > 115 </ sup > Cd with a half-life of 53. 46 hours.

I don't know what makes you think you can get away with this kind of business, and I don't care about that, either.

He finished with the team and filled his pipe and stood looking about him.

The town was about what Wilson expected: one main street with its rows of false-fronted buildings, a water tower, a few warehouses, a single hotel ; ;

My future lay solely with the hall, yet what did I know about the hall at this point??

He'd told Hank Maguire and Luis Hernandez about his wife's refusal to come with him and about what he now intended to do.

With Rod on his way and Matilda visiting with Mrs. Jackson while they searched out familiar names on the face of the cliff, Harmony settled on the edge of the grub box, to ease the pressure of her swollen body on her bone-weary legs, and worried about all that might have happened to Sally.

The valley was only a few hundred yards wide with just about room enough for a properly performed hundred-and-eighty-degree turn.

They'd peddled the soap virtually alone, and without much success, until about a year ago, when -- with the addition of `` SX-21 '' to their secret formula and the inauguration of a high-powered advertising campaign -- sales had soared practically into orbit.

From L'Turu, I heard that until about 1850 the people of this island -- which was about the size of Guam or smaller -- had been of both sexes, and that the normal family life of Melanesian tribes was observed here with minor variations.

All the drivers knew about the plates and they also knew about the big floppy straw hat with shredded edges, the kind natives in travel ads wear when they are out joyfully chopping cane.

She had driven up with her husband in a convertible with Eastern license plates, although the two drivers knew nothing at the moment about that.

And he knew that the men talked about him behind his back, saying that he was one up on everybody else -- including the pilot of the plane with the swastika on it -- because he was chemically incapable of fear.

In China it was a baby sitting on a railroad platform, smudged, blood-specked, with the village burning about him and shells exploding.

At noontime, remembering what the teacher had said about maybe playing with the kids, Jack stayed close to the schoolhouse while all the other big boys, except Charles, went off out the road to play ball.

The white girl with the penetrating green eyes sipped the lemonade handed to her by a handsome man of about 30, who had coppery skin and beetling eyebrows.

In point of fact, this is a beige box with a bright red door, about one and a half feet square and hung from the wall about six feet from the door to Wisman's right.

It has nothing of the proud stride of the trained runner about it, it is not a lope, it is not done with style or verve.

I don't mean a few aesthetes who play about with sensations, like a young prince in a miniature dabbling his hand in a pool.

Steinberg spoke with warmth and enthusiasm about Italy: `` Rome is my second home.

We are worried about what people may do with them -- that some crazy fool may `` push the button ''.

On Fridays, the day when many Persians relax with poetry, talk, and a samovar, people do not, it is true, stream into Chehel Sotun -- a pavilion and garden built by Shah Abbas 2, in the seventeenth century -- but they do retire into hundreds of pavilions throughout the city and up the river valley, which are smaller, more humble copies of the former.

In any social system in which communications have an importance comparable with that of production and other human factors, a point like f in Figure 2 would ( other things being equal ) be the dwelling place for the community leader, while e and h would house the next most important citizens.

The 15th Street deposit is not to be confused with the nearby famous Mayflower Hotel cypress swamp on 17th Street reported in The Washington Post, August 2, 1955, which was probably formed during the second interglacial period and is therefore much younger.

The accuracy of measuring the total electrical energy entering an exploding wire during a few microseconds was verified when two independent types of comparison with the heat energy produced had an uncertainty of less than 2 percent.

and ( 2 ) such other special funds as may, in the discretion of the Secretary of the Treasury, be required each to be a claims fund to be known by the name of the foreign government which has entered into a settlement agreement with the Government of the United States as described in subsection ( A ) of Section 4 of this Title.

The Government of India further agrees in cooperation with the Government of the United States, to coordinate the use of grant and loan funds provided for in paragraphs 1 ( B ) and 1 ( C ) of Article 2, with such direct dollar assistance as may be made available by the Government of the United States of America, so that both sources of financing may be channeled to specific and clearly identifiable economic development programs and projects.

On the remainder of the clear channels, the dominant ( class 1 ) -- B stations are protected as described above, and the relatively small number of secondary ( class 2 ) ) stations permitted to operate on these channels at night are required to operate directionally and/or with reduced power so as to protect the class 1, stations.

In 1947, affidavits were filed with the Commission by various clear-channel stations alleging that extensive interference was being caused to the service areas of these stations during daylight hours, from class 2, stations whose signals were being reflected from the ionosphere so as to create skywave intereference.

In the period since the end of World War 2, -- a period coinciding with merchandising demands for the colorful, the unusual, and the original in signs and displays -- plastics have come on so strong that today they are the acknowledged leaders in the field.

The anode holder shown in figure 2 was designed with two goals in mind.

The upstream gas temperature measured with the thermocouple shown in figure 2 was Af.

Simultaneously with the anode surface temperature and voltage measurements pyrometer readings were taken along the cylindrical surface of the carbon anode holder as indicated on figure 2.

The red cells were used within 2 days after donation and were washed with large amounts of saline before use.

The deep concave gradient employed ( fig. 2 ) was obtained with a nine-chambered gradient elution device ( `` Varigrad '', reference ( 8 ) ) and has been described elsewhere.
