Since the absorption of radio waves in rocklike material varies with wave length, it should be possible to sample the temperature variation at different depths beneath the surface and possibly detect changes in the structure or composition of the lunar surface material.

Douglass prepared his sample of Af by thermal decomposition of aqueous chromic acid at 300 - 325-degrees-C.

One sample, which had been exposed to the atmosphere after evacuation at 375-degrees-C, showed the presence of adsorbed water ( about 0.3 wt ) ) as evidenced by a weak resonance line which was very narrow at room temperature and which disappeared, due to broadening, at low temperature.

The mixtures of sample plus cell suspension were allowed to stand at room temperature for 1 Aj.

For the albumin method, equal volumes of 30% bovine albumin, sample and 2% cells suspended in saline were allowed to stand at room temperature for 1 hr and then were centrifuged at 1000 rpm for 1 Aj.

Children whose reading scores were at least one standard deviation below the regression line of each total third-grade school population were considered under-achievers for the purposes of sample selection.

Efforts were made to take the grab samples at random periods so that the mass of data could be treated as a 6-hr. composite sample.

Upon completion of the purging step, additional initiator appropriate for the molecular weight of the sample desired is added, and the system is then warmed to the polymerization temperature, at which the reaction is allowed to go to completion.

Three specimens for each sample to be tested are required in order to arrive at a satisfactory average of performance.

Sometimes an internal standard is added at a known concentration directly to an analytical sample to aid in quantitation.

Originally it was headerless, being simply 8-bit µ-law-encoded data at an 8000 Hz sample rate.

The application of the pulsed voltage to the sample allows for individual ions at the sample surface to have their electric field, and hence atomic bonding, temporarily disrupted.

This results in ejection of an ionised atom from the sample surface at a known time.

Semi-conductor materials are often analysable in atom probe, however sample preparation may be more difficult, and interpretation of results may be more complex, particularly if the semi-conductor contains phases which evaporate at differing electric field strengths.

This sample was used to synthesize the element ununseptium for the first time in 2009 at the Joint Institute for Nuclear Research, Russia, after it was bombarded with calcium-48 ions for 150 days.

* whiff rate: a term, usually used in reference to pitchers, that divides the number of pitches swung at and missed by the total number of swings in a given sample.

In HPLC the sample is forced by a liquid at high pressure ( the mobile phase ) through a column that is packed with a stationary phase composed of irregularly or spherically shaped particles, a porous monolithic layer, or a porous membrane.

The sample is spotted at one corner of a square plate, developed, air-dried, then rotated by 90 ° and usually redeveloped in a second solvent system.

A sample of households are visited by interviewers who record the details of the household as at census day.

Censuses during independence have been taken 1947, 1960 ( the first comprehensive demographic investigation ), 1970, 1976 ( a sample census ), 1981, 1994 and 2004 and the next would be taken at 2017.

It involves heating the sample at a controlled rate and recording the heat flow either into or from the specimen.

While this loss of precision may be tolerable and viewed as a minor flaw of Algorithm I, it is easy to find data that reveal a major flaw in the naive algorithm: Take the sample to be ( 10 < sup > 9 </ sup > + 4, 10 < sup > 9 </ sup > + 7, 10 < sup > 9 </ sup > + 13, 10 < sup > 9 </ sup > + 16 ).

Thermotropic mesophases are detected and characterized by two major methods, the original method was use of thermal optical microscopy, in which a small sample of the material was placed between two crossed polarizers ; the sample was then heated and cooled.

The problems of maintaining moving parts in vacuum, and of rapidly introducing and withdrawing the sample without losing vacuum, pose major challenges for the design of the instrument.

A major disadvantage of the indirect ELISA is the method of antigen immobilization is not specific ; when serum is used as the source of test antigen, all proteins in the sample may stick to the microtiter plate well, so small concentrations of analyte in serum must compete with other serum proteins when binding to the well surface.

Thyroid nodules is a major presentation of thyroid neoplasms, and is diagnosed by ultrasound guided fine needle aspiration ( USG / FNA ) or frequently by thyroidectomy ( surgical removal and subsequent histological examination ). FNA is the most cost-effective and accurate method of obtaining a biopsy sample.

Eazy-E used a sample of his voice from his recording " Nobody Move, Nobody Get Hurt ", which also became a major hit by Eazy-E with the same title.

* where internal controls are weak, auditors typically rely more on Substantive Tests of Detail ( selecting a sample of items from the major account balances, and finding hard evidence ( e. g. invoices, bank statements ) for those items )

Because of this, keeping the probe tip close enough to the sample for short-range forces to become detectable while preventing the tip from sticking to the surface presents a major problem for non-contact dynamic mode in ambient conditions.

Another major application of AFM ( besides imaging ) is force spectroscopy, the direct measurement of tip-sample interaction forces as a function of the gap between the tip and sample ( the result of this measurement is called a force-distance curve ).

A major factor in this is whether the study sample ( e. g. the research participants ) are representative of the general population along relevant dimensions.

The percentage of galaxies with a particular axis ratio ( minor / major ) for a sample of lenticular and spiral galaxies.

This bulge dominance can be seen in the axis ratio ( i. e. the ratio between the observed minor and major axial of a disk galaxy ) distribution of a lenticular galaxy sample.

One major challenge is various factors that affect the sample and raise the margin of error for the analysis.

In another study, a sample of 217 patients diagnosed with significant hoarding, only 18 % were diagnosed with OCD, as opposed to the 36 % that were diagnosed with a major depressive disorder.

This technology is specifically designed to digitally measure molecular levels of the three major VSCs in a sample of mouth air ( hydrogen sulfide, methyl mercaptan, and dimethyl sulfide ).

The first major revision of the MMPI was the MMPI-2, which was standardized on a new national sample of adults in the United States and released in 1989.

The laboratory is equipped with major facilities including a vibrating sample magnetometer, high pressure mossbauer spectroscope and magnetron sputtering system, along with many others.

Pay television services often, at least two to three times per year, provide subscribers free previews of their services, in order to court potential subscribers by allowing this wider audience to sample the service ; these are typically scheduled to showcase major special event programming, such as the pay cable premiere of a blockbuster feature film or the premiere ( either a series or season premiere ) of a widely anticipated or critically acclaimed original series.

Such was a major event in the history of Maverick's – for reputable Hawaiian big-wave riders to travel to the U. S. mainland to sample the waves of this little-known big wave riding beach.

Thus, analysis of the 993-locus dataset corroborates our earlier results: if enough markers are used with a sufficiently large worldwide sample, individuals can be partitioned into genetic clusters that match major geographic subdivisions of the globe, with some individuals from intermediate geographic locations having mixed membership in the clusters that correspond to neighboring regions.

" Back in the Day " was Ahmad's only major hit single, making it to # 26 on The Billboard Hot 100, # 19 on the US R & B chart on the strength of its hook-a sample of the Teddy Pendergrass song " Love TKO "— and Ahmad's quirky vocal style, reminiscent of Fatlip of the Pharcyde fame, and # 3 on the US rap chart.

The major components of a French press are made of stainless steel to prevent sample contamination.

The major limitations in molecular clinical analysis of tissues include the cumbersome nature of procedures, limited availability of diagnostic reagents and limited patient sample size.
