However, the sibling field of cognitive neuroscience has provided evidence of physiological brain states that directly correlate with mental states-thus providing support for the central assumption of cognitive psychology.

However, once the applied electric field approaches the breakdown value, free electrons become sufficiently accelerated by the electric field to create additional free electrons by colliding, and ionizing, neutral gas atoms or molecules in a process called avalanche breakdown.

However, metal electrode surfaces can cause a region of the vacuum to become conductive by injecting free electrons or ions through either field electron emission or thermionic emission.

However, it remains a commonly used unit for energies in the field of chemistry, and in many countries it remains in common use as a unit of food energy.

However, an errant throw by Tulowitzki sailed past Clint Barmes and into right field, scoring another run and putting runners at 1st and 3rd.

However, whether this is possible depends on how the field of complex numbers is derived in the first place: it may not be possible to distinguish a complex number from its conjugate ( say, 3 + i from 3-i ), since it is impossible to find a property of one that is not also a property of the other, without falling back on the underlying set-theoretic definition.

However, Delphinus is in a rich Milky Way star field.

However, Fahrenheit's interest in natural science led him to begin studies and experimentation in that field.

* However, if we think of as the field of real numbers, then the direct product does not exist-naively defining in a similar manner to the above examples would not result in a field since the element does not have a multiplicative inverse.

However, charges and currents produce EMR only indirectly — rather, in EMR, both the magnetic and electric fields are produced by changes in the other type of field, not directly by charges and currents.

However, in the far-field EM radiation which is described by the two source-free Maxwell curl operator equations, a more correct description is that a time-change in one type of field is proportional to a space-change in the other.

However, despite the insight of many of his observations, his own conclusions are open to suspicion because of his failure to employ at all times the correct research methods.

However, when philosophy attempts to stand above the sciences, to dictate the conditions of empirical research, it becomes formal metaphysics ; ;

However, after reading the work of French sociologists Émile Durkheim and Marcel Mauss, Radcliffe-Brown published an account of his research ( entitled simply The Andaman Islanders ) that paid close attention to the meaning and purpose of rituals and myths.

However, Paris ignored the powerful developments in quantitative studies underway in the U. S. and Britain, which reshaped economic, political and demographic research in those countries, while France fell behind.

However, commonly there are delays in regulatory and legislative actions to limit the use of antibacterials, attributable partly to resistance against such regulation by industries using or selling antibacterials, and to the time required for research to test causal links between antibacterial use and resistance.

However in the United Kingdom, pioneering research into painting materials and conservation, ceramics, and stone conservation was conducted by Arthur Pillans Laurie, academic chemist and Principal of Heriot-Watt University from 1900.

However, as of 2011 adoption of the new terms has been slow and usage has been limited in the marketplace and in the press, with notable exceptions such as Linux operating systems, several textbooks and scientific research papers.

However, both the Soviet Union and Iraq, at a minimum, secretly defied the treaty and continued research and production of offensive biological weapons, despite being signatories to it.

However, now that the archeological archives and research results of the former USSR are open to scientists, it has become quite clear that the primal sighthound type evolved between the Kyrgyzstan, the lower Kazakhstan part of Altai and the Afghan plains, and that the earliest actual sighthound breeds were the plains Afghan hounds and the Kyrgyz Taigan.

However, it is frequently used as a resource for academic research papers.

However research concludes that this change would have been insufficient to cause the observed level of ammonite extinction.

However, excessive cycling while standing can cause knee damage It used to be thought that cycling while standing was less energy efficient, but recent research has proven this not to be true.

However, current research shows that several trapping mechanisms immobilize the CO < sub > 2 </ sub > underground, reducing the risk of leakage.

However, when the research team synthesized element 98, they could not think of a good analogy for dysprosium, and instead named the element californium in honor of the state in which it was synthesized.

However, research and knowledge are brought into the design process through the judgment and common sense of designers – by designers " thinking on their feet " – more than through the predictable and controlled process stipulated by the Rational Model.

However, it was not until the 19th century that research into the subject started to intensify.

However, certain conditions must be met before the replication of the experiment is commenced: the original research question has been published in a peer-reviewed journal or widely cited, the researcher is independent of the original experiment, the researcher must first try to replicate the original findings using the original data, and the write-up should state that the study conducted is a replication study that tried to follow the original study as strictly as possible.

However, some patients fail to show any significant improvement from TMS which indicates the need for further research of this treatment.

However, recently a transfection vector was developed and the transfection conditions for E. invadens were optimised which should enhance the research possibilities at the molecular level of the differentiation process.
