We report on the enhanced mechanical properties of ∼60 nm thick W-Mo-O nanocomposite films, which are of current interest as structural and electrode materials in photo-related energy technologies. W-Mo-O films were sputter-deposited onto Si(100) by varying the growth temperature (Ts) ranging from 25 to 500 °C. The molybdenum (Mo) content in the films was varied in the range of y = 0.05–0.15 by employing the W-Mo target with a variable Mo content. Structural and mechanical characterization was performed to understand the combined effect of the Mo content and Ts on the structure and mechanical behavior of W-Mo-O films. The results indicate that the effect of Ts is significant on the growth and microstructure of W-Mo-O films. The effect of the Mo-content is reflected in elevating the Ts needed for film crystallization coupled with the average grain-size reduction. Structural studies revealed that the W-Mo-O films were amorphous for Ts ≤ 300 °C, at which point amorphous-to-crystalline transformation occurs. Monoclinic (m) W-Mo-O nanocomposite films exhibit a combination of m-WO3 and m-MoO3 phases with m-WO3 being predominant in the matrix. The peak intensities of the m-MoO3 phase increases with increasing Mo-content. The nanoindentation results indicate a non-monotonic mechanical response in terms of hardness (H) and reduced elastic modulus (Er) of the deposited films with increasing Ts. The effect of microstructure evolution is remarkable on the mechanical properties. Structural transformation at Ts = 300 °C induces a significant change in H and Er values. The W-Mo-O with y = 0.05 exhibit maximum H (∼21 GPa) and Er (∼216 GPa), where Mo-incorporation induced enhancement in mechanical characteristics is pronounced. A strain rate dependence of the H value of W-Mo-O films has been observed. Based on the results, structure-composition-mechanical property correlation in W-Mo-O films is established.

n this paper, the impact of awareness programs as well as treatment on an SIR model has been investigated. We assume that the whole population is divided into four compartments, named as susceptible (S), infected (I), aware susceptible (Sa) and recovered (R). Analytical findings and numerical simulations of the model show that if the exposure to the awareness program is high and adequate treatment is available, then the infection can be eliminated. Analysis of the model also depicts that if treatment is not available, then infection is high even if enough awareness is present. But in absence of awareness an infection can not be eliminated inspite of adequate treatment. Effective treatment can led to a diminished level of infection. Stability analysis of the model is investigated by using stability theory of differential equations. Further, numerical simulations are carried out to validate the analytical results.

Background: To study maternal and fetal outcome in antenatal patients with heart failure. Methods: The present study was conducted on pregnant female with heart failure admitted to hospital UISEMH, Kanpur from January 2012 to August, 2013. We attended 6800 pregnant female admitted to hospital out of which 48 pregnant female had heart failure during pregnancy or in labour. This was descriptive observational study. Results: Percentage of pregnant female with heart failure in our study was 0.7%. The mean of age distribution in pregnant patients with heart failure is 22.66 ± 2.82 years. Primigravida and primipara contributed to major group with 77.09% (37/48). Delivery was conducted in 33.3%, while 60.4% were expired. 4% of cases lost follow-up. None of patient belonged to AHA class A or B of heart failure. 37.5% were in AHA class C while 62.5% were in class D. Early diagnosis was made in only 16.58% of cases. 75% of early diagnosed case survived in comparison to 32% of late diagnosis. 31.25% cases delivered term healthy babies, 37.5% were dead born and pre-term and small for gestation babies are 12.5% and 18.75% respectively. Of dead born 66.6% were macerated and 33.3% were fresh stillbirths. Among survivals 57% had ventilator support. Conclusion: Early diagnosis and prompt management improves outcome. Maternal and fetal outcome is dependent on time of diagnosis, severity of heart failure and ventilator support.
