Opis:: Elastic anisotropy and acoustic attenuation in bulk material consisting of consolidated graphene nanoplatelets are studied. The material was prepared by spark plasma sintering, and exhibits highly anisotropic microstructure with the graphene nanoplatelets oriented perpendicular to the spark plasma sintering compression axis. The complete tensor of elastic constants is obtained using a combination of two ultrasonic methods: the through-transmission method and the resonant ultrasound spectroscopy. It is shown that the examined material exhibits very strong anisotropy both in the elasticity (the Young moduli in directions parallel to the graphene nanoplatelets and perpendicular to them differ by more than 20 times) and in the attenuation, where the dissipative effect of the internal friction in the graphene nanoplatelets combines with strong scattering losses due to the porosity. The results are compared with those obtained for ceramic-matrix/graphene nanoplatelet composites by the same ultrasonic methods.

Opis:: We use a seed-mediated growth to fabricate gold nanorods in water solution. By changing the amount of silver salt we demonstrate the control of aspect ratio of the obtained rods. The microscopic and spectroscopic analyses provide ways to characterize the morphology and the optical properties of the gold nanorods. Nanorods synthesized using this approach feature length of the order of 50-60 nm, which translates into longitudinal plasmon resonances in the near infrared spectrum region.

Opis:: Background. Literature among fishermen of India is scanty. The external factors like diet, quality of dental hygiene and environmental factors have an effect on oral health. Moreover elderly age group offer very little importance towards their oral health. Objective. To assess the prosthetic status and prosthetic treatment needs among the geriatric fishermen population of Kutch coast, Gujarat, India. Material and Methods. A cross sectional descriptive study was conducted among 1200 elderly people (above 60 years) of Kutch coast, Gujarat, India. They were interviewed and examined using a proforma designed with the help of WHO Oral Health Survey 1997. Chi square test was used for comparisons. Confidence level and p-value were set at 95% and 5% respectively. Results. Out of 1200 elderly people, 836 were males and 364 were females. Considering the prosthetic status, majority (76.7%) had no prosthesis followed by full removable dentures (12.3%). An insight into the prosthetic needs showed that majority (27.3%) had a need for multiunit prosthesis. Conclusion. In this study, it was seen that overall prosthetic status was low and prosthetic need was high. Therefore new avenues have to be discovered to make the prosthetic treatment readily available to the elderly.
