The variation of electrical resistivity of an insulator-conductor composite, namely, wax-graphite composite, with parameters such as volume fraction, grain size, and temperature has been studied. A model is proposed to explain the observed variations, which assumes that the texture of the composite consists of insulator granules coated with conducting particles. The resistivity of these materials is controlled mainly by the contact resistance between the conducting particles and the number of contacts each particle has with its neighbors. The variation of resistivity with temperature has also been explained with the help of this model and it is attributed to the change in contact area.

Most of the lesions in the oral cavity have papillary appearance. Oral squamous papilloma (SP) is one such type, which is a benign proliferation of the stratified squamous epithelium and presents as papillary or verrucous exophytic mass induced by human papillomavirus (HPV). Most of the oral mucosal lesions are often asymptomatic and have small progression. The common sites of occurrence include tongue, soft palate, and uvula. Squamous papilloma arising on hard palate is described in this article. Surgical excision of the lesion was done and sent for histopathological analyses that confirmed the clinical diagnosis. In larynx and trachea, malignant transformation of papillomas has been reported. The potentially malignant nature of SP if present needs to be explored.How to cite this article: Chaitanya P, Martha S, Punithvathy R, Reddy M.

There have been several strategies proposed to realise adiabatic circuits. Most of them require a clock signal and also its complement form. In this investigation, the authors we propose a family of adiabatic circuits, which consist of two branches and which enable control of charging and discharging of the capacitive load only by the input signal, work with single time varying supply and with no need of complementary inputs. A mathematical expression has been developed to explain the energy dissipation in our adiabatic inverter circuit. Measurements of energy drawn, recovered and dissipated have been carried out through simulation and, they are the same as obtained from the theoretical expression. In the proposed circuit, the input and output logic levels are approximately the same and can be used for building cascaded logic circuits. The energy saving in this family is to the tune of 50% compared with CMOS circuits constructed with similar circuit parameters, up to 250 MHZ. The authors have described the proposed inverter, NAND gates, NOR gates, adder circuits and JK flip-flop along with their simulation results. 518

Introduction: The use of antibiotics in recent years has become more aggressive and more common. The inappropriate use, to be more precise, the abuse of these prescriptions, is the root cause for increasing bacterial resistance and adverse outcomes. Antisepsis can be suggested as an appropriate alternative to antibiotics, to control the increasing antibiotic resistance among individuals. Objective: The objective of this study was to compare the awareness of antibiotic prescription and resistance among BDS and MDS practitioners and students. Materials and Methods: A total of 361 dental professionals were included in this study. Each of them was given a questionnaire containing questions pertaining to antibiotic prescription and awareness. Results: Most of the participants prescribed antibiotics as pre and post treatment management of all the oral diseases during their routine interaction with the patients. Overprescription of antibiotics, amoxicillin being the most common, was significantly more among the BDS practitioners than the MDS practitioners. BDS practitioners (78%) preferred a 3-day antibiotic prescription whereas MDS practitioners (80%) prescribed a 5-day course, which was statistically significant. Mindfulness with respect to antimicrobial prophylaxis and antibiotic resistance was observed to be satisfactory in both the groups. However, there was a general absence of mindfulness with respect to the rules for antibiotic prescription recommendations in both the groups. Conclusion: Antibiotic prescription should be given with care to prevent its resistance, an upcoming iatrogenic health hazard.
