However, if neither of these organisms is isolated, it is necessary to send stool specimens to a reference laboratory.

However, the differences in behavioral, chronobiological, morphometrical, hematological and biochemical parameters are relatively small and fall into the expected range of interstrain variations in other laboratory animals.

However, the study also found that when a small number of the highest-quality studies from one laboratory were analyzed, the effect size was not significant.

However, these experiments were not conducted in a controlled scientific laboratory environment.

However, a study of Dalton's own laboratory notebooks, discovered in the rooms of the Lit & Phil, concluded that so far from Dalton being led by his search for an explanation of the law of multiple proportions to the idea that chemical combination consists in the interaction of atoms of definite and characteristic weight, the idea of atoms arose in his mind as a purely physical concept, forced upon him by study of the physical properties of the atmosphere and other gases.

However, in his laboratory notebook under the date 6 September 1803 there appears a list in which he sets out the relative weights of the atoms of a number of elements, derived from analysis of water, ammonia, carbon dioxide, etc.

However, it is useful to distinguish between artificial selection that is unintentional or involves manipulating the environment only, and artificial selection that alter internal DNA sequences in the laboratory.

However, other notable laboratory tests, such as immune function tests, were relatively normal.

However, diagnosis depends to a considerable extent on the position of the patient ’ s unique set point for T4 and T3 within the laboratory reference range ( an important issue that is further elaborated below ).

However, he did not win because his nominations were not specific to any discovery and were based on a variety of laboratory findings.

However, despite the praise from the Soviet Union government, the money that poured out to support his laboratory, and the honours he was given, Pavlov made no attempts to conceal the disapproval and contempt in which he held Soviet Communism.

However, laboratory experiments have shown that fish do react to painful stimuli ( e. g. injections of bee venom ) in a similar way to mammals.

However, for research applications such as mRNA measurements, a specialist laboratory is required.

However, these are sophisticated and delicate instruments, only adapted to the national standardization laboratory.

However, for the elements 104, 105 and 106 there was a controversy between a Soviet laboratory and an American laboratory regarding which one had discovered them.

However, the Weizmann Institute scientists provided extensive documentation that they had been developing this idea using an antibody against that Schlessinger's laboratory had developed and generated, and that he had given them for these studies.

However, in 1890, facing financial problems, Edison was forced to lay off most of the laboratory employees, including Fessenden.

However, Parsons did store many volatile chemicals and compounds in his laboratory and had been working to finish a contract for a special effects firm.

However after burning with a bright light for some minutes in his laboratory, the lamp broke down due to excessive current.

However, the use of placebos as treatment in clinical medicine ( as opposed to laboratory research ) is ethically problematic as it introduces deception and dishonesty into the doctor-patient relationship.

However, wild rats generally have larger brains, hearts, livers, kidneys, and adrenal glands than laboratory rats.

However, while policy makers consider suffering to be the central issue and see animal euthanasia as a way to reduce suffering, others, such as the RSPCA, argue that the lives of laboratory animals have intrinsic value.

However, Negroponte retained the role of laboratory Chairman.

However, no diagram of her brain patterns, no early I.Q. tests recorded certain essential facts about Helva that Central must eventually learn.

However, gene tests may not detect every mutation associated with a particular condition because many are as yet undiscovered.

However, by identifying clusters of observable properties that are associated with core examples of clitics on the one hand, and core examples of affixes on the other, one can pick out a battery of tests that provide an empirical foundation for a clitic / affix distinction.

However, when the new test subjects take the older tests, in almost every case their average scores are significantly above 100.

However, after doing some screen tests and storyboards, Toho figured Jet Jaguar would not be able to carry the film on his own, either in screen appearance or marketing value, so they shut the project down during pre-production.

However, he failed to reach fifty in the next two tests and four ODIs as both series were drawn.

However, in tests conducted on rhesus monkeys, the analgesic potency of hydrocodone was actually found to be higher than that of morphine.

However, in the case of Griggs v. Duke Power Co. in 1971, for the purpose of minimizing employment practices that disparately impacted racial minorities, the U. S. Supreme Court banned the use of IQ tests in employment, except when linked to job performance via a Job analysis.

However, IQ tests may well be biased when used in other situations.

However, it has been challenged as to whether the measurement of job performance is usually done through pencil / paper tests, job skills tests, on-site hands-on tests, off-site hands-on tests, high-fidelity simulations, symbolic simulations, task ratings and global ratings.

However, when the new test subjects take the older tests, in almost every case their average scores are significantly above 100.

However, if failures occur mostly on weekends, many uniform-distribution tests such as K-S would miss this, since weekends are spread throughout the year.

However, on tests with a heterogeneous distribution of point values — i. e. different questions are worth different point values — it is more difficult to provide choices.

However, like methadone, buprenorphine produces similar cognitive dehabilitation in multiple areas of mental function in both memory and timed choice task tests, which may persist after cessation of substitution treatment.

However, the issue is not finally settled, for each of these experimental tests has left open at least one loophole by which it is possible to question the validity of the results.

* However, aquarium tests showed:

However, Hammer worked primarily on the incandescent electric lamp and was put in charge of tests and records on that device.

However, DNA tests on Dunbar's son and nephew revealed the two were not related, thus establishing that the boy found in 1912 was not Bobby Dunbar, whose real fate remains unknown.

However, there are recordings with substantial low frequency content that most conventional loudspeakers are ill-equipped to handle without the help of a subwoofer, especially at high playback levels, such as music for pipe organs with 32 ' bass pipes ( 16 Hz ), very large bass drums on symphony orchestra recordings and electronic music with extremely low synth bass parts, such as bass tests or bass songs.

" However, if additional evidence is available, from theory and / or from experiment ( such as density dependence ), there is no obstacle to incisive tests of the Arrhenius law.

" However, Ertl's most recent tests show that subroutine threading is faster than direct threading in 15 out of 25 test cases.
