ABSTRACT
In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method and their morphological and spectral properties were investigated using XRD, SEM, FTIR, and Raman spectroscopy. XRD studies of powder samples revealed the presence of an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which were prepared through two different chemical routes, showed no additional phases. A detailed analysis of the FTIR and micro-Raman spectra of the composite samples revealed the formation of stable ZIF structures inside the macropores of the MCG substrate. The hydrophilic nature of the MCG substrate and its interaction with the ZIF structure resulted in the formation of stable ZIF-MCG composites. We believe that these composite materials may find a wide range of important applications in the field of sensors, molecular sieving.
ABSTRACT
Economic loss due to traffic accidents is noticeable in India; however, the country lacks research works to estimate the magnitude. This study is an attempt through a Stated Preference (SP) survey to know how users value safety and how much they are willing to pay (WTP) for a safer road facility to reduce the risk of their involvement in road traffic accidents. The survey was conducted for two-wheeler riders of selected roads in Calicut City. Attributes selected for SP experimental design includes travel time, travel cost and traffic accidents per year and Binary Logit model was used to determine the WTP values. It was observed that travel cost, accident rate of the route selected, age, occupation, personal income and number of household members have significant impact on the decision-making process. WTP value of a road accident for a two-wheeler user was found to be Rs 0.53/person/trip.

This video describes the transobturator outside in suburethral sling surgical procedure for the indication of urodynamic stress urinary incontinence. A total of 170 cases were performed from January 2007 till December 2013. The average follow up was from 6 months till 7 years. The cure rate was 90%. There were no recurrences in our series. There was one patient with tape exposure after 3 years which required excision.
