The genus Echthronomas Forster, 1869 and two species, Echthronomasfacialis (Thomson, 1887) and Echthronomasquadrinotata (Thomson, 1887), are recorded for the fauna of Ukraine for the first time. Descriptions and photographs of species are provided.

In this work, we have calculated the Joule-Thomson inversion curve of two important associating fluids, namely water and methanol, from the SAFT equation of state. Comparisons with the available experimental data, for water and methanol indicate that this molecular based equation of state gives good prediction of the low temperature branch; but, unfortunately, due to lack of isenthalpic dat...

10.1083/jcb.200801036 Thomson Scientifi c has posted a response ( 1 ) to our editorial on the reliability of their impact factor data ( 2 ). In it, they claim that our interpretation of the communication between our offi ce and their Research Services Group was “ misleading and inaccurate ” . We have already published some excerpts from these communications in our previous editorial. For propri...

ABOUT 35 YEARS AGO a young inexperienced and very nervous student entered Wards 1 and 2 of the Royal Victoria Hospital, Belfast, as resident pupil. The same student-I hope I am still capable of learning-stands before you this evening and hopes you will receive him as graciously as Professor W. W. D. Thomson did on that occasion. He shook my hand and welcomed me as a new member of his team. This...

The modified Thomson problem, which concerns an assembly of N particles mutually interacting through a Coulombic potential and subject to a Coulombic-harmonic confinement, is introduced. For sufficiently strong confinement strengths M, properties of its solutions (such as the energy and the particle positions at the minimum, and the corresponding zero-point vibrational energy) are accurately es...

Rothmund-Thomson syndrome (RTS) is a genodermatosis presenting with a characteristic facial rash (poikiloderma) associated with short stature, sparse scalp hair, sparse or absent eyelashes and/or eyebrows, juvenile cataracts, skeletal abnormalities, radial ray defects, premature aging and a predisposition to cancer. The prevalence is unknown but around 300 cases have been reported in the litera...

We present the first remotely operated vehicle investigation of megabenthic communities (1004-1695 m water depth) on the Hebrides Terrace Seamount (Northeast Atlantic). Conductivity-temperature-depth casts showed rapid light attenuation below the summit and an oceanographic regime on the flanks consistent with an internal tide, and high short-term variability in water temperature, salinity, lig...

Collective Thomson scattering (CTS) measurements provide information about the composition and velocity distribution of confined ion populations in fusion plasmas. The bulk ion part of the CTS spectrum is dominated by scattering off fluctuations driven by the motion of thermalized ion populations. It thus contains information about the ion temperature, rotation velocity, and plasma composition....
