The objectives of this study were to evaluate two models of postnatal care using a questionnaire incorporating the Parents' Postpartum Sense of Security (PPSS) instrument and to test the validity of the PPSS instrument.
There were significant correlations between the total PPSS scores and scores for postpartum talks and visits to the breastfeeding clinic.
Irrespective of group, there were significant correlations between the total PPSS scores and women's positive views on the usefulness of postpartum talks, rho = -0.18 (p = 0.04).
There was also a significant correlation between total PPSS scores and women's positive views on the usefulness of the breastfeeding clinic, rho = 0.24 (p = 0.004).
A stand-alone point-focus parabolic solar still (PPSS) was designed and fabricated for desalination of seawater or brackish water and purification of non-potable water.
The Number of responders (80% vs 70%), dropouts (16% vs 18%) and relapsers (12.5 vs 14.5%) did not differ between COSS and PPSS.
The primary outcome measures used for comparing COSS and PPSS were: 1) number of responders ; 2) number of dropouts 3) cost per detoxified patient, 4) number of relapsers at 6 months follow-up.
Since there are three fracture parameters (NSIF, NTOD, and PPSS) with changeable notch opening angle in two basic relationships, it is necessary to select one critical parameter with changeable notch opening angle or two independent critical parameters, respectively.
The influence of polymerization conditions on the nucleophilic substitution step polymerization of high molecular weight poly phenylene sulfide sulfone) (PPSS) has been studied and optimized with respect to molecular weight for the system 4,4′-dichlorodiphenylsulfone, sodium sulfide, NMP/water/sodium acetate.
The experimental results demonstrate that compared with Probability-based target Prediction and Sleep Scheduling strategy (PPSS), KPNS scheme improves the energy efficiency by 60%, and can reduce target missing rate and tracking delay to 66%, 75% respectively.
