Continuous Functional Calculus for Quaternionic Bounded Normal Operators

In this article we give an approach to define continuous functional calculus for bounded quaternionic normal operators defined on a right quaternionic Hilbert space.Comment: Submitted to a journal. There was a gap in the previous version. We have corrected it and stated all the results for bounded cas

On the polar decomposition of right linear operators in quaternionic Hilbert spaces

In this article we prove the existence of the polar decomposition for densely defined closed right linear operators in quaternionic Hilbert spaces: If $T$ is a densely defined closed right linear operator in a quaternionic Hilbert space $H$, then there exists a partial isometry $U_{0}$ such that $T = U_{0}|T|$. In fact $U_{0}$ is unique if $N(U_{0}) = N(T)$. In particular, if $H$ is separable and $U$ is a partial isometry with $T = U|T|$, then we prove that $U = U_{0}$ if and only if either $N(T) = \{0\}$ or $R(T)^{\bot} = \{0\}$.Comment: 17 page

New Occurrences of Cymothoa eremita in Coachwhip trevally, Carangoides oblongus (Cuvier, 1833) along Karaikal, Southern Coast of lndia

Parasitic fish diseases are oneof the mast importantpmblems in the fisheries sector. Cymothoidsare obligatory parasites, mostly infesting the cornmenially important fishes. They are blood suckers living in the skin surface, gill filaments, and or in bud cavity of fishes

Transmigration of intrauterine contraceptive devices: embedded in urinary bladder wall in pregnant woman

Globally, 14% of reproductive aged women use intrauterine contraception. The five intrauterine contraceptive devices (IUCDs) currently approved are chemically active and continually elute either copper or levonorgestrel. Uterine perforation is most serious and rare complication which can be acute or chronic in nature. Although uncommon, uterine embedment and perforation can occur. We report case of transmigration of intrauterine contraceptive device into the urinary bladder wall perforating the uterine wall in 25-year-old gravid female. She was subjected to ultrasound abdomen and pelvis which unveiled the diagnosis of migrated copper-T. Under spinal anaesthesia, laparotomy was done and IUCD was removed

IoT based Driver Drowsiness and Pothole Detection Alert System

One of the common in progressing countries is the maintenance of roads. Well maintained roads contribute a major portion to the country’s economy. Identification of pavement distress such as potholes and humps not only help drivers to avoid accidents or vehicle damages, but also helps authorities to maintain roads. This paper discusses various pothole detection methods that have been developed and proposes a simple and cost-effective solution to identify the potholes and humps on roads and provide timely alerts to drivers to avoid accidents or vehicle damages. Not only Potholes and humps are the main cause of accidents other than over speeding and drowsiness of driver includes the issue of accidents. Drowsy state may be caused by lack of sleep, medication, tiredness, drugs or driving continuously for long period of time. So, here is the solution for detecting the potholes and humps and to alert the driver from drowsiness while driving. In this paper, the system is structured to detect potholes and to alert the drowsy driver by using the ultrasonic sensor, eyeblink sensor and IR sensor and microcontroller. Ultrasonic sensor senses the humps, IR sensor senses the potholes and eye blink sensor the blinking of eye and this sensing signals fed into the Arduino to alert the driver by buzzer sound

Synthesis and Structural Analysis of Nanocrystalline MnFe2O4

AbstractNanocrystalline form of manganese ferrite (MnFe2O4) has been synthesized by simple sol-gel auto combustion method using citric acid as chelating agent. The obtained nanocrystalline powders of manganese ferrite were subjected to structural and magnetic measurements. Temperature dependent magnetization was also carried out for the single phase nanocrystalline manganese ferrite and the results have been discussed in detail

A Case Control study to Compare the Prevalence of Periodontal Disease in patients With and Without Systemic Autoimmune Diseases

AIM OF THE STUDY: The aim of the study is to find, whether the presence of systemic autoimmune diseases in an individual is a risk factor for the development of Periodontal disease. MATERIALS AND METHODS: A sample of 253 patients with Systemic autoimmune diseases, attending the Rheumatology department of Madras Medical College and Government General Hospital, Chennai-3 and 262 patients without Systemic autoimmune diseases, attending the outpatient department of the Tamilnadu Government Dental College and Hospital, Chennai -3 constituted the case and control groups. Age, gender and Oral hygiene status matching was done. Oral hygiene status was assessed using Oral Hygiene Index original and Periodontal status was assessed using Community Periodontal Index in association with Loss of Attachment Index. Statistical analysis was done using SPSS version 15. RESULTS: Results showed 99.2% and 73.9% prevalence of gingivitis and periodontitis respectivelyin the case group as compared to 85.5% and 14.9% in the control group. Results also showed no linear relationship between oral hygiene scores (OHI-original) and prevalence of periodontitis (CPI & LOA scores) in case group. CONCLUSION: Patients suffering from systemic autoimmune diseases showed more prevalence of periodontal diseases irrespective of oral hygiene scores. Hence one may assume that the presence of systemic autoimmune diseases in a patient leads to risk in development of periodontal disease. Conversely in patients with periodontal disease with no local factors, one must rule out any undiagnosed systemic autoimmune diseases
