Scoping the Possibilities: Student Preferences towards Open Textbooks Adoption for E-Learning  [PDF]
Deepak Prasad, Tsuyoshi Usagawa
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.524227
Abstract: Many universities have begun implementing e-Learning systems due to their low cost. However, publishers of expensive textbooks stand in the way of e-Learning’s ability to provide a cost-effective educational delivery model. While many universities aim to overcome this opposition and replace traditional publishers’ textbooks with free open textbooks, such plans cannot be executed successfully unless students are open to their use. As such, a study into students’ preferences towards open textbook adoption is vital to provide clear indication as to their opinions regarding open textbook use. Thus, this study conducted a study of University of the South Pacific (USP) students’ preferences towards open textbook adoption for e-Learning using a survey administered during Semester 2, 2013 which generated 1077 responses. Areas examined include: Impacts of textbook costs on students’ academic careers; preferences towards open textbook adoption; perceived barriers to and motivations for adoption of open textbooks; and preferred digital features and reading devices. Results show that textbook prices adversely impact students. Furthermore, a high level of acceptance towards the adoption of open textbooks was found. The study revealed that the preference for reading printed material was the highest rated barrier to open textbook adoption, while the free availability of open textbooks was rated the greatest motivator. Study findings are being used to inform efforts to develop open textbooks at the USP and may assist other universities seeking to start similar projects.
Evaluation of an aminobisphosphonate (alendronate) in the management of periodontal osseous defects
Veena H,Prasad Deepak
Journal of the Indian Society of Periodontology , 2010,
Abstract: Background and Objectives: Alendronate, an aminobisphosphonate, is capable of inhibiting periodontitis associated osteoclastic activity and hence is effective in protecting the alveolar bone in periodontitis. In the present study, we explored the efficacy of local delivery of alendronate on the alveolar bone following mucoperiosteal flap surgery. This is the first study to use polymer impregnated gel based delivery of alendronate. Materials and Methods: A total of 15 patients with chronic periodontitis in the age group of 35 - 55 years, of both sexes, with pocket depth of ≥ 5mm and radiographic evidence of identical osseous defects in the mandibular molar region bilaterally were included in this prospective study. A gel based drug delivery system of Alendronate was formulated. Following surgical flap debridement, 0.1 ml alendronate gel and 0.1 ml placebo gel was placed at the experimental and control sites respectively. Clinical and radiographic parameters were recorded at baseline, three months and six months post surgery. Results: Alendronate was more effective in improving clinical and radiographic parameters compared to placebo. Interpretation and Conclusion: Alendronate is effective in the management of periodontitis associated bone loss. Gel based local delivery of the drug addresses the critical concern of exposing the patient to adverse effects of systemic administration.
Treatment of gingival pigmentation : A case series
Prasad Deepak,Sunil S,Mishra R,Sheshadri
Indian Journal of Dental Research , 2005,
Abstract: A smile expresses a feeling of joy, success, sensuality, affection and courtesy, and reveals self confidence and kindness. The harmony of the smile is determined not only by the shape, the position and the color of the teeth but also by the gingival tissues. Gingival health and appearance are essential components of an attractive smile. Gingival pigmentation results from melanin granules, which are produced by melanoblasts. The degree of pigmentation depends on melanoblastic activity. Although melanin pigmentation of the gingiva is completely benign and does not present a medical problem, complaints of ′black gums′ are common particularly in patients having a very high smile line (gummy smile). For depigmentation of gingiva different treatment modalities have been reported like- Bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery and laser. In the present case series bur abrasion, scraping, partial thickness flap (epithelial excision) cryotherapy and electrosurgery have been tried for depigmentation, which are simple, effective and yield good results, along with good patient satisfaction. The problems encountered with some of these techniques have also been discussed.
Adding Sputum Collection and Transportation Services for Early Identification TB Cases in Hard-to-Reach Difficult Terrain—Will It Help?  [PDF]
Badri Thapa, Banuru Muralidhara Prasad, Sarabjit Singh Chadha, Subrat Mohanty, Deepak R. Mishra, Jamie Tonsing
Journal of Tuberculosis Research (JTR) , 2017, DOI: 10.4236/jtr.2017.54023
Abstract: A community engagement project was designed and implemented to reach 10.6 million population in 13 districts of Uttarakhand state—India, to identify presumptive TB patients (PTBPs) and link to free diagnostics services, either through referral or sputum collection and transportation (SCT). The objective of this study is to determine additional yield of TB patients achieved by providing SCT services in comparison to referrals of PTBPs identified in hard-to-reach areas. This was before and after comparative study conducted between April-June 2014 (2Q2014-before) to July-September 2014 (3Q2014-after). SCT was advised for all PTBPs identified from community level interventions between July-September 2014 (3Q2014-after). In 3Q2014, additional 279 (34%) PTBPs were examined in the microscopy centre with an additional 36 (51%) new smear positive (NSP) patient diagnosed. A total of 46 NSP (128%) were contributed by SCT alone. Higher proportion (94%) of TB patients was initiated on treatment in 3Q2014 in comparison to 2Q2014 (91%). SCT as a strategy for early case detection in hard-to-reach difficult terrain yields positive results in comparison to mere referral of PTBPs.
A modified double pedicle graft technique and other mucogingival interceptive surgeries for the management of impacted teeth : A case series
Sunil S,Avinash B,Prasad Deepak,Jagadish Leka
Indian Journal of Dental Research , 2006,
Abstract: Maxillary canine is one of the most common teeth that are impacted. This accounts for 1-2% of all patients who attend orthodontic treatment. The key to achieve maximal eruption of these teeth is their surgical exposure and the role of periodontist in such situations is to provide a functional and satisfactory width of attached gingiva on the labial surface. There are different techniques to surgically expose the impacted teeth, namely--gingivectomy technique, apically positioned flap, closed eruption technique, modified apically positioned flap, double pedicle flap and free gingival graft. Selection of the procedure is dependent on the positioning of the tooth in relation to mucogingival junction and attached gingiva. In the present case series we describe three different techniques for uncovering of impacted teeth, which are apically positioned flap, closed eruption technique and a modified double pedicle graft specially planned for the situation. These procedures when selected diligently using sound selection criteria will create adequate width of attached gingiva which minimizes or eliminates the future mucogingival problems.

Metal-insulator transitions in tetrahedral semiconductors under lattice change
Shailesh Shukla,Deepak Kumar,Nitya Nath Shukla,Rajendra Prasad
Physics , 2004, DOI: 10.1142/S0217979204024525
Abstract: Although most insulators are expected to undergo insulator to metal transition on lattice compression, tetrahedral semiconductors Si, GaAs and InSb can become metallic on compression as well as by expansion. We focus on the transition by expansion which is rather peculiar; in all cases the direct gap at $\Gamma$ point closes on expansion and thereafter a zero-gap state persists over a wide range of lattice constant. The solids become metallic at an expansion of 13 % to 15 % when an electron fermi surface around L-point and a hole fermi surface at $\Gamma$-point develop. We provide an understanding of this behavior in terms of arguments based on symmetry and simple tight-binding considerations. We also report results on the critical behavior of conductivity in the metal phase and the static dielectric constant in the insulating phase and find common behaviour. We consider the possibility of excitonic phases and distortions which might intervene between insulating and metallic phases.
Mapping Cloud Computing onto Useful e-Governance
Ajay Prasad,Sandeep Chaurasia,Arjun Singh,Deepak Gour
Computer Science , 2010,
Abstract: Most of the services viewed in context to grid and cloud computing are mostly confined to services that are available for intellectual purposes. The grid or cloud computing are large scale distributed systems. The essence of large scale distribution can only be realized if the services are rendered to common man. The only organization which has exposure to almost every single resident is the respective governments in every country. As the size of population increases so the need for a larger purview arises. The problem of having a large purview can be solved by means of large scale grid for online services. The government services can be rendered through fully customized Service-oriented Clouds. In this paper we are presenting tight similarities between generic government functioning and the service oriented grid/cloud approach. Also, we will discuss the major issues in establishing services oriented grids for governmental organization.
Benchmarking recognition results on word image datasets
Deepak Kumar,M N Anil Prasad,A G Ramakrishnan
Computer Science , 2012,
Abstract: We have benchmarked the maximum obtainable recognition accuracy on various word image datasets using manual segmentation and a currently available commercial OCR. We have developed a Matlab program, with graphical user interface, for semi-automated pixel level segmentation of word images. We discuss the advantages of pixel level annotation. We have covered five databases adding up to over 3600 word images. These word images have been cropped from camera captured scene, born-digital and street view images. We recognize the segmented word image using the trial version of Nuance Omnipage OCR. We also discuss, how the degradations introduced during acquisition or inaccuracies introduced during creation of word images affect the recognition of the word present in the image. Word images for different kinds of degradations and correction for slant and curvy nature of words are also discussed. The word recognition rates obtained on ICDAR 2003, Sign evaluation, Street view, Born-digital and ICDAR 2011 datasets are 83.9%, 89.3%, 79.6%, 88.5% and 86.7% respectively.
