Importance of implementation disease prevention programs temporomandibular joint in elderly and senile
The aim of the study was to increase the effectiveness of prevention of dysfunctional states of the temporomandibular joint (TMJ) in elderly and senile age by developing and implementing new approaches to health education as part of the creation and implementation of the program «Prevention of diseases of the temporomandibular joint in elderly and senile». To achieve the objectives were examined 86 patients from 60 to 83 years: 25 patients with symptoms of diseases TMJ found as a result of uptake with complaints of difficulty in chewing, aesthetic dissatisfaction, and 61 patients who were sent for consultation gnathology doctors another profile under the program "Prevention of diseases of the temporomandibular joint in elderly and senile.

Properties of very n -rich He isotopes
Low-energy spectra of the 8, 10He nuclei were investigated in the (t, p) -type reactions at small centre-of-mass angles using ∼ 25 AMeV beams of 6He and 8He nuclei. The 0+ ground state (g.s.) of 8He and excited states, 2+ at 3.6-3.9MeV and (1+) at 5.3-5.5MeV, were populated with cross-sections of 200, 100-250, and 90-125μb/sr, respectively. To account for a near-threshold anomaly observed in the 8He spectrum the population of a 1- continuum (soft dipole excitation) was considered. The lowest-energy group of events in the 10He spectrum was observed at ∼ 3 MeV with a cross-section of ∼ 140 μb/sr. This result is consistent with the previously reported observation of 10He providing a new g.s. position for 10He at about 3MeV
New insights into the resonance states of H and He
International audienceThe H system was produced in the H(t, p) H reaction studied at small CM angles with a 58MeV tritium ion beam. High statistics data were used to reconstruct the energy and angular correlations between the H decay fragments. A broad structure in the H missing-mass spectrum showing up above 2.5MeV was identified as a mixture of the and states. The data also present an evidence that the ground state of H is located at about 2MeV. Then, the H and He systems were explored by means of transfer reactions occurring in the interactions of 132MeV He beam nuclei with deuterium. In the H( He, H) reaction a T = 3/2 isobaric analog state of H in He was observed at an excitation energy of 22.0±0.3MeV with a width of 2.5±0.3MeV
The He and He spectra studied in the , reaction
18 pages, 8 figures, submitted to Phys. Lett. BThe low-lying spectra of He and He nuclei were studied in the H(He,)He and H(He,)He transfer reactions. The ground state (g.s.) of He and excited states, at MeV and at MeV, were populated with cross sections of 200, 100-250, and 90-125 b/sr, respectively. Some evidence for He state at about 7.5 MeV is obtained. We discuss a possible nature of the near-threshold anomaly above 2.14 MeV in He and relate it to the population of a continuum (soft dipole excitation) with peak value at about 3 MeV. The lowest energy group of events in the He spectrum was observed at MeV with a cross section of b/sr. We argue that this result is possibly consistent with the previously reported observation of He, in that case providing a new g.s. position for He at about 3 MeV
Correlation studies of the H spectrum
The nuclear system H was studied using the H(,)H transfer reaction at a laboratory energy of 57.7 MeV and small center of mass angles. The energy and angular correlations among the H decay fragments were obtained by complete kinematical reconstruction. A broad structure in the H missing mass spectrum above 2.5 MeV with a typical width of several MeV was identified as a mixture of and states. Analysis of interference patterns observed in the measured angular correlations disclosed the ground state of H concealed in the smooth missing mass spectrum. The deduced values for the resonance energy and width are MeV and \Gamma_{\text{g.s.}\approx 1.3 MeV. The estimated cross sections for population of the ground state and the doublet of excited states at are b/sr and mb/sr, respectively
Observation of Excited States in H 5
The excited states in the 5H system, which was produced in the 3H(t, p)5H reaction with a 58 MeV tritium beam at c.m. angles were investigated. The reconstruction of the energy and angular correlations between the 5H decay fragments was performed by using high statistics data. It was observed that a broad structure in the 5H missing mass spectrum above 2.5 MeV was identified as a mixture of the 3/2+ and 5/2+ states. The results show that the 3/2+ and 5/2+ states are either almost degenerate or the reaction mechanism causes a very specific interference of these states.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
