Beta asymmetry parameter in the decay of 114In
The beta asymmetry parameter A for the pure Gamow-Teller decay of 114In is
reported. The low temperature nuclear orientation method was combined with a
GEANT4 based simulation code allowing for the first time to address in detail
the effects of scattering and of the magnetic field. The result, A = -0.994 +/-
0.010stat +/- 0.010syst, constitutes the most accurate value for the asymmetry
parameter of a nuclear beta transition to date. The value is in agreement with
the Standard Model prediction of A = -1 and provides new limits on tensor type
charged weak currents.Comment: 11 pages, 2 figures; additional information was added on systematic
effects, the magnetic field map and the calculation of the Qcos(theta) value
Sliding wear of a-C:H coatings against alumina in corrosive media
This paper reports the results obtained from the study of friction and sliding wear in two corrosive solutions of an a-C:H coating deposited on 316L stainless against an alumina ball, employed as static counter part. Calculations of the values of the von Mises stresses developed at the coating–substrate interface, as soon as the ball touches the coated sample, and how this state of stress influences the response of the coated system under the corrosion environment, are presented and discussed. The results obtained from these calculations, as well as from the experiments conducted in the present research, are compared with other experiments published in the literature, where a-C:H coatings deposited on different substrates and with different coating architectures were tested in similar corrosive media. It has been determined that in those systems, where the von Mises stress in the coating, found in the vicinity of the interface, exceeds the threshold value of approximately 370MPa, coating failure with spallation will take place, regardless of the substrate nature on which this coating has been deposited. From this analysis it has been concluded that the coating yield strength is of utmost importance in conferring the a-C:H coated system there quired stability in a corrosive solution
Епідигматичний модус англійських числівників
У статті розглядаються англійські числівники, денумеративи та їх епідигматичний модус. Семантична структура порівнюваних груп розглядаються на векторах їх походження та модифікації. Частиномовна представленість досліджується на просторах їх граматичного, семантичного і словотворчого буття. Визначаються перспективи подальшого дослідження.

The semantic structures of both groups are being focused upon. The words under analysis are viewed in terms of their initial and secondary grounds. The item of part of speech charge is being considered in terms of grammatical, semantic and epidigmatic aspects. Thus, the modus of the paradigmatic groups have been considered wide perspectives for further investigation.

Autonomy in participation in cerebral palsy from childhood to adulthood
Aim To determine the long-term development of autonomy in participation of individuals with cerebral palsy (CP) without intellectual disability. Method Individuals with CP (n=189, 117 males, 72 females; mean age [SD] 21y 11mo [4y 11mo], range 12-34y); were assessed cross-sectionally (46%) or up to four times (54%), between the ages of 12 and 34 years. Autonomy in participation was classified using phase 3 of the Rotterdam Transition Profile. A logistic generalized estimating equation regression model was used to analyse autonomy in six domains (independent variables: age, Gross Motor Function Classification System [GMFCS] level, and interaction between age and GMFCS level). Proportions of autonomy were compared to references using binomial tests (pIndividuals with cerebral palsy without intellectual disability achieved autonomy in most participation domains. Regarding intimate relationships, they continued to have less experience compared to age-matched references. Development of autonomy was less favourable for individuals in Gross Motor Function Classification System levels III to V.</p

The half-life of Fr in Si and Au at 4K and at mK temperatures
The half-life of the decaying nucleus Fr was determined in
different environments, i.e. embedded in Si at 4 K, and embedded in Au at 4 K
and about 20 mK. No differences in half-life for these different conditions
were observed within 0.1%. Furthermore, we quote a new value for the absolute
half-life of Fr of t = 286.1(10) s, which is of comparable
precision to the most precise value available in literature
