Ternary Association Reaction of Vibrationally Cold N Ions in Ambient Helium.

The rate coefficients for the ternary association reaction of vibrationally cold N ions with N and He were measured in an afterglow plasma in the temperature range of 140-250 K: = (1.02 ± 0.39)(300/) × 10 cm s.

Overtone Transition 2ν of HCO and HOC: Origin, Radiative Lifetime, Collisional Quenching.

We present spectra of the first overtone vibration transition of C-H/ O-H stretch (2ν) in HCO and HOC, recorded using a laser induced reaction action scheme inside a cryogenic 22 pole radio frequency trap. Band origins have been located at 6078.68411(19) and 6360.

Recombination of vibrationally cold N2+ ions with electrons.

Recombination of vibrationally cold N2+ ions with electrons was studied in the temperature range of 140-250 K. A cryogenic stationary afterglow apparatus equipped with cavity ring-down spectrometer and microwave diagnostics was utilized to probe in situ the time evolutions of number densities of particular rotational and vibrational states of N2+ ions and of electrons. The obtained value of the recombination rate coefficient for the recombination of the vibrational ground state of N2+ with electrons is αv=0 = (2.

[The increased sensitivity of dentin: the mechanisms of remineralization using toothpaste with tin fluoride].

The purpose of the study was clinical and laboratory analysis of the remineralizing properties and clinical efficacy of the course application of the Sensodyne Rapid Relief therapeutic and prophylactic toothpaste for sensitive teeth with tin fluoride. The study involved 50 overwise healthy patients aged from 18 to 25 years diagnosed with a localized form of hyperesthesia of hard dental tissues and no signs of acute inflammation of periodontal tissues. After 7 days of clinical observation and daily use of the toothpaste the hygienic condition of the oral cavity in all patients improved: oral hygiene index was 1.

[Further evidence that the serotonin transporter gene is associated with schizotypal traits in a healthy Russian population].

Genetic factors are thought to contribute to schizotypal dimensions. Recently, a number of genetic variants associated with schizotypal traits in psychiatrically healthy people have been found. Authors reported earlier the association between the SERT 5-HTTLPR polymorphism and schizotypal traits measured with MMPI.
