Asepsis in Operative Dentistry and Endodontics

Operative (Conservative) dentistry and endodontics are specialties of dentistry where the operator is exposed to various infectious agents either via contact with infected tissues, fluids or aerosol. The potential for cross infection to happen at the dental office is great and every dentist must have a thorough knowledge of the concepts of sterilization and disinfection. Disposables should be used wherever possible. Furthermore, the water supply to the dental chair units and water outlets can house biofilms of microbes and should be considered as possible sources of infection. This review discusses the importance of following strict aseptic protocols from the perspective of operative dentistry and endodontics

A Network Structure for Diagnosis of Four Types of Faults in Reed-Muller Canonical Circuits

In this paper, a new network structure and its associated universal test set, independent of the circuit function, and dependent only on the number of function variables, with good fault diagnosing capabilities have been proposed for single stuck-at, double stuck-at, AND-bridging and OR-bridging faults in Exclusive-OR Sum of Products (ESOP) Reed-Muller Canonical (RMC) circuits

City, Caught in Nets An Interactive Illustration

Interactive Illustration is an attempt to fuse creative writing with visual design. The initial idea was to have an interesting artwork presented on screens, which users can interact with and get engaged in another set of interesting artworks. It started as an experiment taking inspiration from the text “City, Caught in Nets“ provided by my guide. Later it turned out as main project. The project is based on Mumbai, which depicts the life of people and their association with the Sea. It also covers the life of “Kolis - The Fishermen residing in coastal areas”, people and business from “Dharavi”. Illustrations are done with watercolours as a medium which are know for being versatile and flexible that can be used in different ways to achieve different results. These Illustrations were then processed to be used on web. Research have been done and many references were taken to get better understanding of the community and their daily routine. The website was made interactive with the help of GIFs, CSS animations and JavaScript. Sound is added to make it more immersive

Hostel Rooms

This project is the output of the learning of photography. When we think about the room, we see it in 3D form. People create 3D structures of the room in software to see how it will look in real life. I was inspired by that and tried to create an IIT Hyderabad hostel room in miniature form through the medium of photography. When we remove the roof of the hostel room and go beyond how it is visible. I tried to create the 360-degree environment of the hostel room with flat 2D photography. This project I did it for my experience. I hope you will also experience the same by seeing this exhibition too. In this process, the learning behind this project is, how to photography from a different perspective. Usually, people do the usual type of photography. I want it to do it in a different form and viewpoint. The result is a photography exhibition in which I am showing the recreation of the hostel room in a small type and study the mood and environment of the rooms

Analysis of τ-mesons

We describe in this paper measurements made on the decay products of 11 τ-mesons observed in large nuclear emulsion block detectors. Out of the 33 charged decay products; 27 have been arrested in the block, and were identified as π-mesons. The charge of the τ-meson was found to be positive in 6 cases. In one case the charge of the τ-meson is possibly negative and in 4 cases it could not be determined. Omitting one τ-meson in which a high energy γ-ray is emitted and which has been reported earlier the weighted mean Q-value of the remaining 10 τ-mesons is: Qτ = 76.3 ± 0.3MeV which gives the mass of the τ -meson as: mτ =968.7 ± 0.6me This value is slightly higher than the mean value 965.5 ± 0.7m e compiled by Amaldiet al. from measurements of various laboratories

Diffusion profiles of high dosage Cr and V ions implanted into silicon

The depth profiles of high dosage Cr-52(+) and V-51(+) ions implanted in (100) crystalline silicon after thermal anneal at temperatures between 300 degreesC and 1000 degreesC are studied by secondary ion mass spectrometry and cross-sectional transmission electron microscopy. At dosages of 1x10(15) ions/cm(2) and above, the surface layer of silicon substrate is amorphorized. During the subsequent thermal annealing, the depth profiles of the implanted ions are strongly coupled with the solid phase epitaxial growth of amorphous silicon. Silicide precipitate formation is important to understand the differences between Cr and V diffusion. After anneal of the 1x10(15) ions/cm(2) implanted samples at 900 degreesC and 1000 degreesC, most of the Cr has left the silicon, but only 10% of the V has escaped. The 1x10(14) ions/cm(2) Cr-implanted sample shows Cr ions exist only near the surface after 1000 degreesC anneal. The V-implanted sample, on the other hand, only shows a narrowing of the V profile after 1000 degreesC anneal

Application of Tribology Concept in Dental Composites Field: A Scoping Review

Tribology is the discipline concerning the application of friction, lubrication, and wear concepts of interacting surfaces in relative motion. A growing interest has developed in tribology application in medical biomaterials, such as resin composites used in restorative dentistry. Yet, the keywords “tribology” and “biotribology” are little applied in the pertinent publications. The aim of this scoping review was to offer an overview of tribology application in dental composites research and to identify knowledge gaps and address future research. A literature search was conducted on Pubmed and Scopus databases and the studies investigating the tribological behavior of resin composites were included for qualitative synthesis. The majority of studies on dental tribology were published in the research areas of mechanical engineering/nanotechnology and differed in several methodological aspects. The preponderant engineering approach and the lack of standardized testing make the laboratory findings poorly informative for clinicians. Future research should focus on the tribological behavior of dental materials composites by means of an integrated approach, i.e., engineering and clinical, for improving development and advancement in this field of research
