On contrast enhancement techniques for medical images with edge detection: a comparative analysis
The main role of contrast enhancement is increasing the quality of any image. This technique plays fundamental role in medical images. Edge detection is also playing an instrumental role in medical imaging because all information has preserved in edges. Digital image includes a pixel which has fixed number of rows and columns. People can see the internal structure of the body through digital image. Five images have taken as an example in this paper, namely hand, brain, head, ankle and knee. Three enhancement techniques have used, namely Fuzzy Type-II, INT Operator and Fuzzy Type-I. These different three techniques have applied on different images which are used in this paper. Three parameters have used to compare three contrast enhancement techniques. Peak signal to noise ratio (PSNR), root mean square error (RMSE) and mean square error (MSE) quality parameters have been used. The result has produced after comparison of three approaches on five images. In the end, Fuzzy Type-I technique produces the better resultant image
Dayal Kaur Khalsa: The art of remembering
In the space of three years in the late eighties, Dayal Kaur Khalsa wrote and illustrated a series of picture books that constitute a visual (auto)biography. In these books, Khalsa explores the meaning and reliability of memory, and the importance of family context in life history. By evoking popular culture and its artifacts in her illustrations, Khalsaprovides afully realised, time-specific world for her character May to inhabit. Furthermore, through the device of self- referential visual quotations, by means of which characters and settings reappear from book to book, Khalsa creates a form of "visual intertextuality" unique in the canon of Canadian picture books.Peer reviewedfinal article publishe
Rupi Kaur: Women’s Writing Tradition in Translation
This paper will present a brief background of the author, Rupi Kaur, and her artistic work, focusing in her poetry. The book approached is Honey and Milk, and it will be analysed though the feminist criticism theory of Elaine Showalter in order to discuss the poetry of Kaur in the context of the third phase of women’s writing. To achieve that, this paper will discuss some selected poetry and some details about the translation of the book to the Portuguese Brazilian language and the rewriting entailed in the process of translation
Determination and potential importance of diterpene (kaur-16-ene) emitted from dominant coniferous trees in Japan
Reactive volatile organic compounds (VOCs) are known to affect atmospheric chemistry. Biogenic VOCs (BVOCs) have a significant impact on regional air quality due to their large emission rates and high reactivities. Diterpenes (most particularly, kaur-16-ene) were detected in all of the 205 enclosure air samples collected over multiple seasons at two different sites from Cryptomeria japonica and Chamaecyparis obtusa trees, the dominant coniferous trees in Japan,. The emission rate of kaur-16-ene, was determined to be from 0.01 to 7.1 μg dwg^[-1] h^[-1] (average: 0.61 μg dwg^[-1] h^[-1]) employing branch enclosure measurements using adsorbent sampling followed by solid phase-liquid extraction techniques. The emission rate was comparable to that of monoterpenes, which is known major BVOC emissions, collected from the same branches. In addition, total emission of kaur-16-ene at 30℃ was estimated to exceed that of total anthropogenic VOC emissions
Nanodiamonds as novel nanomaterials for biomedical applications: drug delivery and imaging systems
Randeep Kaur, Ildiko BadeaDrug Design and Discovery Research Group, College of Pharmacy and Nutrition, University of Saskatchewan, Saskatoon, Saskatchewan, CanadaAbstract: Detonation nanodiamonds (NDs) are emerging as delivery vehicles for small chemical drugs and macromolecular biotechnology products due to their primary particle size of 4 to 5 nm, stable inert core, reactive surface, and ability to form hydrogels. Nanoprobe technology capitalizes on the intrinsic fluorescence, high refractive index, and unique Raman signal of the NDs, rendering them attractive for in vitro and in vivo imaging applications. This review provides a brief introduction of the various types of NDs and describes the development of procedures that have led to stable single-digit-sized ND dispersions, a crucial feature for drug delivery systems and nanoprobes. Various approaches used for functionalizing the surface of NDs are highlighted, along with a discussion of their biocompatibility status. The utilization of NDs to provide sustained release and improve the dispersion of hydrophobic molecules, of which chemotherapeutic drugs are the most investigated, is described. The prospects of improving the intracellular delivery of nucleic acids by using NDs as a platform are exemplified. The photoluminescent and optical scattering properties of NDs, together with their applications in cellular labeling, are also reviewed. Considering the progress that has been made in understanding the properties of NDs, they can be envisioned as highly efficient drug delivery and imaging biomaterials for use in animals and humans.Keywords: dispersion, surface functionalization, toxicity, carriers, fluorescence, light scatterin
A randomized control study comparing outcomes in student nurses who utilize video during simulation debriefing as compared to those who utilize traditional debriefing
Clinical placement sites for nursing students have become limited around the country. An alternative teaching strategy must be employed to allow for students to gain valuable knowledge and skills. High fidelity human patient simulation is one such strategy that allows students to safely practice nursing interventions in a controlled environment using a scenario. Students participate in groups and may be video recorded for replay during the debriefing session, the most essential learning element of the simulation session. Students watching a video recording of their participation in the scenario allow them to reflect on their own actions to identify their own strengths and weaknesses. The research question for this study was the following: what are the effects of video assisted debriefing as compared to traditional oral debriefing on student outcomes (clinical judgment, self-confidence, learner satisfaction scores with simulation and learner satisfaction scores with the simulation facilitator) of associate degree nursing students in their second year of nursing school? A randomized control design was employed to test the research question using a sample of 74 students. Students were randomized into either a video assisted debriefing group and an oral assisted debriefing group. The debriefing sessions were structured for each group with the only difference being the video assisted debriefing group watched the recording of their videotaped simulation session. Results included higher self-reported clinical judgment, learner satisfaction scores with the simulation, and learner satisfaction with the debriefing facilitator. Findings from this study support the use of video assisted debriefing as compared to traditional oral assisted debriefing after a simulation session. Debriefing should be a highly structured part of simulation allowing for students to learn and develop important cognitive and behavioral skills. Video debriefing is an important component of simulation that allows for improved student outcomes.Ph. D.Includes bibliographical referencesIncludes vitaby Tresa Kaur Dusa
GRAYSCALE IMAGE WATERMARK DETECTION
A Digital watermarking is a technique that provides a solution to the longstanding problems faced with copyrighting digital data. Digital watermarks are pieces of information added to digital data (audio, video, or still images) that can be detected or extracted later to make an assertion about the data. This information can be textual data about the author, its copyright, etc; or it can be an image itself. Watermarking Based on DCT Coefficient Modulation technique embeds the watermark in the DCT domain to increase the robustness of the watermarking scheme.DCT based watermarking is an example of frequency domain watermarking. The objective of this research work is to implement DCT based watermarking technique on gray scale image. The study focuses on evaluating the robustness of watermarked image after having three different attacks on watermarked image and extraction of watermark from that particular image. To compare the DCT based watermarking with LSB based watermarking and to validate the proposed work & the comparative results of watermarking using DCT and LSB are also presented. This paper recommends DCT based technique for achieving robustness in digital image watermarking.</jats:p
Mechanical and infectious complications of central venous catheterizations in a tertiary-level intensive care unit in northern India
Background: Central venous catheters (CVC) are associated with mechanical, infectious and thrombotic complications. Aims: To study (a) the incidence of mechanical and infectious complications of CVC insertions and to compare, (b) the rates of these complications between the internal jugular venous (IJV) and the subclavian venous (SCV) accesses. Settings and Design: An adult intensive care unit of a tertiary care hospital. Prospective, observational study. Methods: All landmark-based CVC insertions performed between 1 st October 2008 and 30 th September 2009 were prospectively studied for mechanical and infectious complications. Statistical Analysis: SPSS software for Windows, Version SPSS 16.0, and Epi Info (3.5.1) software. Results: Four hundred and eighty central venous catheterizations were studied (IJV route, 241 and SCV route, 239). Mechanical complications occurred in 86 patients (17.9%, bleeding complications-48, catheter-related complications-27 and pneumothorax-11). The IJV route was associated with a significantly higher incidence of bleeding complications (P=0.009). Forty-seven patients had infectious complications (9.79%), like exit site infections (n=17), catheter tip infections (n=22) and catheter-related bloodstream infections (CRBSIs) (n=8). The risks of infectious complications increased significantly if the CVC was in situ for longer than 7 days (P=0.009), especially with IJV cannulae. The incidence density of CVC tip infections was 7.67 per 1000 catheter days and of CRBSIs was 2.79 per 1000 catheter days. Conclusions: Bleeding complications occurred more frequently with IJV insertions and infectious complications occurred more commonly in cannulae that were left in situ for longer than 7 days
