Development of Hypervideo Platform Using Object Databases
No full textWeb users are seizing on interactive capabilities that software suppliers have developed so far, and are eagerly awaiting new interactive capabilities now being demonstrated. This paper focuses the development of rich information environment based on a customized platform enabling hyperlinks on objects within a digital video. With the help of such environment, the viewer is able to view multiple videos concurrently and browse them temporally as well as spatially with the help of an object database. Specifically, the platform enables to traverse through that object by linking, and such links have been explored and created. The link may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base (static, generic or dynamic) and object database versus multiple videos are also investigated

Object-database approach for a hypervideo platform
No full textWeb users are seizing on interactive capabilities that software suppliers have developed, and are eagerly awaiting new interactive capabilities now being demonstrated. The capabilities currently being explored include video browsing. This paper focuses on the development of a rich information environment based on a customized platform that enables hyperlinks on objects within a digital video. With the help of such an environment, the user is able to view multiple videos concurrently and browse them spatially and temporally, with the help of an object database. Specifically, the platform is expected to enable users to traverse through that object by linking, and such links have been explored. The links may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base and object database versus multiple videos are also investigated
Are Two Interviews Better Than One? Memory across Repeated Cognitive Interviews.
No full textEyewitnesses to a filmed event were interviewed twice using a Cognitive Interview to examine the effects of variations in delay between the repeated interviews (immediately & 2 days; immediately & 7 days; 7 & 9 days) and the identity of the interviewers (same or different across the two repeated interviews). Hypermnesia (an increase in total amount of information recalled in the repeated interview) occurred without any decrease in the overall accuracy. Reminiscence (the recall of new information in the repeated interview) was also found in all conditions but was least apparent in the longest delay condition, and came with little cost to the overall accuracy of information gathered. The number of errors, increased across the interviews, but the relative accuracy of participants' responses was unaffected. However, when accuracy was calculated based on all unique details provided across both interviews and compared to the accuracy of recall in just the first interview it was found to be slightly lower. The identity of the interviewer (whether the same or different across interviews) had no effects on the number of correct details. There was an increase in recall of new details with little cost to the overall accuracy of information gathered. Importantly, these results suggest that witnesses are unlikely to report everything they remember during a single Cognitive Interview, however exhaustive, and a second opportunity to recall information about the events in question may provide investigators with additional information
Public exposure from I-131 hospitalized isolated patients in NIMRA Jamshoro Pakistan
No full textPurpose/ Background: To treat the cancerous tissues the unsealed radioisotopes are being in clinical practice since 7 decades. From these unsealed sources, I-131 is the choice of treatment for the treating thyroid cancers. Orally administered I-131 patients are to be kept isolated in hospital for some period until captured activity in the body reaches to national and international limits for the avoidance of unacceptably high radiation exposures to patients' family members and the general public to keep ALARA (as low as reasonably achievable) principal in mind. The main rationale of this study was to calculate the exposure/dose of the general public. Material and Methods: This work presents the exposure rate and dose to the general public in the corridor and the non-radioactive patients admitted in adjacent room from I-131 administered isolated patients treated at NIMRA (Nuclear Institute of Medicine and Radiotherapy) Jamshoro Pakistan. In this study exposure from 23 thyroid cancer patients treated with different activities of I-131 (50 to 200 mCi) from January 2011 to December 2012 were included. Results: The average exposure rate in the corridor was about 5.17 µSv/hr (2.14 µSv/hr to 8.15 µSv/hr) and the cumulative dose to nonradioactive patients residing in an adjacent room was 0.647 mSv (0.192 mSv to 1.664 mSv). Conclusion: This study concludes that the exposure rate to the general public especially the admitted non-radioactive patient in the adjacent room is almost within the limits of 1 mSv as specified in national and international standards.-----------------------------------------Cite this article as: Memon SA, Laghari NA, Qureshi ST, Ahmad A, Khan AA, Hussain MM.

Effect of iron limitation on the production of Streptolysin S (SLS) of <i>Streptococcus pyogenes</i> Group A
No full textThe effect of iron on the growth of <i>Streptococcus pyogenes</i> Group A and its influence on Streptolysisn S (SLS) production was investigated. Two strains of <i>S. pyogenes</i> used in this study C203S and 55903 M were grown in iron-restricted medium. The iron chelator, (Ethylenediamindi-(o- hydroxyphenyl-acetic acid) (EDDA) was added at a concentration giving a 10-fold molar excess over Fe. Successful growth of strains of <i>S. pyogenes</i> was obtained suggesting no absolute requirement for iron in the growth and the yield of SLS was not affected by the concentration of iron in the growth medium
Integrated photonic devices with silicon oxycarbide
No full textIn this paper, we report on the potential of silicon oxycarbide (SiOC) for integrated photonic applications. SiOC films are developed by reactive radio frequency magnetron sputtering from a silicon carbide (SiC) target in the presence of argon and oxygen gases. The optical properties of the developed SiOC film are characterized with spectroscopic ellispometry over a broad wavelength range 300-1600 nm. The refractive index n of the SiOC film is 2.2 at wavelength lambda = 1550 nm and the extinction coefficient k is estimated to be less than 10(-4) in the near-infrared region above 600 nm. The topography of SiOC films is studied with AFM showing very smooth surface, with rms roughness of 0.24 nm. SiOC film with refractive index n = 2.2 is then patterned by direct laser-writing lithography and etched with reactive ion etching to realize high contrast SiOC core optical waveguides for integrated photonics applications. The waveguide losses are characterized at telecommunication wavelength lambda = 1550 nm. As an example of photonic integrated devices integrating SiOC films, a microring resonator is fabricated where a SiOC layer is used as a coating material for the core of a silicon oxynitride (SiON) waveguide
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
