Spatially selective narrow band and broadband absorption in Ag/SiO/Ag based trilayer thin films by oblique angle deposition of SiOlayer.

We have experimentally demonstrated spatially selective absorption in Ag-SiO-Ag based trilayer thin films by tuning the deposition angle of SiOlayer. These structures generate cavity resonance which can be tuned across the substrate locations due to spatially selective thickness and refractive index of silicon oxide (SiO) film sandwiched between metallic silver (Ag) mirrors. Spatially selective property of SiOfilm is obtained by oblique angle deposition technique using an electron beam evaporation system.

Early Clinical Exposure as a Learning Tool to Teach Neuroanatomy for First Year MBBS Students.

Context: Early clinical exposure (ECE) is one of the important tools to teach basic science to the MBBS students. It is one form of vertical integration between basic science and clinical subjects. This study is an effort at exploring the use of ECE as a motivational tool toward better learning in neuroanatomy for first year MBBS students.

Comparative Study on Insall-Salvati Index by Radiological and Clinical Methods in a Tertiary Care Centre of North Bengal, India.

Introduction: Patellar height is an important parameter of patellar stability. Its importance is evident from various attempts to measure it, by different scientists from time to time and many indices have been derived among which Insall-Salvati index (IS index) is the most simple, accurate and easy to measure. In this study a new clinical method has been tried to measure patellar height by applying the same principle of IS index.

Variation of Axial Ocular Dimensions with Age, Sex, Height, BMI-and Their Relation to Refractive Status.

Background: Myopia is one of the most common causes of visual impairment worldwide.It is proved in earlier studies that the eye shape is different in myopic and nonmyopic children even at a very young age, with the former manifesting asymmetric axial globe elongation and the latter global expansion but limited information is available regarding hypermetropia.

Aim: To find out the variations of axial ocular dimensions in relation to age, sex, height and to demonstrate any possible correlation of body mass index (BMI) in myopic hypermetropic and emmetropic patients.

Change of patellar height with age and sex.

Patellar height is one of the important parameter in patellar stability. Growth spurt or excessive physical strain can lead to high-riding patella or patella alta. But this is not yet proved.
