The superconducting phase of Calcium under the pressure at 200 GPa: the strong-coupling description

The thermodynamic parameters of the superconducting state in Calcium under the pressure at 200 GPa have been determined. The numerical analysis by using the Eliashberg equations in the mixed representation has been conducted. It has been stated, that the critical temperature ($T_{C}$) decreases from 36.15 K to 20.79 K dependently on the assumed value of the Coulomb pseudopotential ($\mu^{*}\in$). Next, the order parameter near the temperature of zero Kelvin ($\Delta(0)$) has been obtained. It has been proven, that the dimensionless ratio $2\Delta(0)/k_{B}T_{C}$ decreases from 4.25 to 3.90 together with the growth of $\mu^{*}$. Finally, the ratio of the electron effective mass to the electron bare mass ($m^{*}_{e}/m_{e}$) has been calculated. It has been shown, that $m^{*}_{e}/m_{e}$ takes the high value in the whole range of the superconducting phase's existence, and its maximum is equal to 2.23 for T=T_{C}.Comment: 5 pages, 5 figure

The Meeting Center Support Programme (MCSP), a combined support programme for people with dementia (PWD) and their caregivers: first results in Italy after 7 months of attendance

Objectives: The MEETINGDEM Project aims to implement an innovative approach to support people with mild-moderate dementia (PWD) and their families in Italy, Poland and UK. This person-centered approach (Meeting Center Support Programme -MCSP-) has already been implemented in the Netherlands and demonstrated benefits (reduced behavioural and mood problems -BPSD-, delayed admission to residential care, higher levels of carer competence and lower levels of burden). MCSP proposes activities to stimulate PWD, support for caregivers (CGS) and actions for both. Our aim is to investigate differences between PWD and CGS partipating in two Italian Centers (Milano Zona 4 , Milano Zona 7; N=26+26) and an Italian control group (CTR -usual care- N=10+10). Materials and Methods: PWD were recruited according to the Global Deterioration Scale score (GDS: 4-5). Dyads of both groups were assessed at the beginning of participation in the project (T0) and after 7 months (T1) to collect data about behavioural disturbances and distress level through NeuroPsychiatric Inventory (NPI) administration. Results: At first T0-T1 design was applied (ANCOVA repeated measures 2x2, taking into account the baseline data and potential confounders as covariates). Our preliminary results are from NPI data: CGS \u394 distress is statistically different in MCSP vs CTR group (p=0.002; covariates: Center, age, education years, cohabitation); \u394 BPSD gravity (FxG) (p=0.034; covariates: Center, age, education years). Applying multiple regression to a four-factor model of NPI about CGS \u394 distress we find that in MCSP group \u2018Behavioural\u2019 (p=0.015) and \u2018Euphoria\u2019 (p=0.019) factors can predict the distress pattern whereas in CTR group only \u2018Behavioural\u2019 factor (p=0.022) can predict it. Discussion: Significant differences were found in perceived distress by caregivers: these first preliminary data support the efficacy of the MCSP approach to sustain caregivers of PWD. A significant difference was also found regarding FxG of BPSD. This finding is in agreement with previous studies demonstrating the efficacy of multidimensional approaches to reduce BPSD. Conclusion: We present preliminary results about BPSD of PWD and caregiver distress. These results suggest that dementia impact on quality of life of caregivers could be decreased and BPSD could be reduced by combining support for PWD and their carers
