Fluoride contaminated water has become a major concern in many regions. In the present work a hybrid water purifier has been developed in order to enhance daily distillate and for delivery of fluoride free water. Two sources namely biomass/biogas and solar energy is used to heat and hence evaporate the water. Evaporated water vapour is condensed before it is collected as distillate. Performance of the water purifier was carried out at 5 (five) different water volumes (10, 15, 20, 25 and 30 litres) and at different quantities of fuel burning (2, 3, 3.5 and 5 kg) and solar radiation. Based on the experiment, it has been observed that maximum distillate of 5.5 litre has been observed in 4 hours for water volume of 10 litres. The performance of the hybrid is found to be enhanced with the incorporation of condenserKeywords

Literally, the term asphyxia means absence of pulsation (pulselessness), though its usage in Forensic Medicine has generally come to mean a lack of oxygen. Actually Asphyxia is best described as an interference with respiration due to any cause - Mechanical, Environmental, or Toxic1. During the year 2011 and 2012, 2777 and 2793 autopsies were conducted in the mortuary of the department of Forensic Medicine, Gauhati Medical College and Hospital, Guwahati, out of which asphyxial deaths were 15.8% and 19% respectively. So there is an enough scope of doing such an important study as the number of such cases is high. In this study at the Gauhati Medical College, Guwahati, Assam during the period from 1st July 2012 to 30th June 2013, out of the 2772 cases being autopsied in mortuary, 320 (11.54%) cases were of deaths due to asphyxia. Hanging topped the list with 250(78.12%) cases followed by drowning, 64(20%) cases, strangulation, 3 (0.94%) cases and choking, 3(0.94%) cases. The others epidemiological data, i.e. occupation, motive and circumstances of the death, etc. were discussed to know the pattern of asphyxial death cases as well as way of preventions by adopting certain measures.Keywords

In the present study, a new method is proposed for temperature controlling by combustion staging. Two combustion stages can be used with two stages of fuel feeding. A high stoichiometric ratio (SR) λ > 1 is used at the first stage to mitigate adiabatic flame temperature (AFT) in case of high O2% in the oxidant. For validation, a series of experiments are conducted using mini-CFB (circulating fluidized bed), and an oxidant of 100% O2 concentration is used with three SR ratios, i.e. λ = 1.25, 2.0 and 3.0. The resulting average temperatures along the riser for biomass are 1031°C, 950°C and 798°C; and for coal 1129°C, 1051°C and 961°C respectively. The controlling of AFT with pure oxy-fuel combustion eliminates the recycled flue gas in oxy-fuel CFB combustion and flue gas recirculation section; this simplifies design, fabrication and installing-operating costs of the power plants. Familiarizing this concept can accelerate adapting oxy-fuel combustion in CFB power plants for carbon capturing and sequestration. This study can help commercialize the third generation of oxy-fuel CFB combustion with zero RFG. Finally, the concept of controlling AFT by SR is validated experimentally.Keywords

Introduction: Expert testimony is very much essential in any civil as well as criminal trials. Forensic medicine experts, those who are called to the court for their professional view must be amply qualified for the job. If there is any dental injury relating to a crime or dental malpractice, forensic dentist are also called for expert opinion.
Objectives: Collecting different anecdotes from different journals and other source, this paper has reviewed the role and importance of forensic dentists in the field of forensic investigation.
Discussion: In any massacre of natural disaster or any crime scene involving single or multiple murders, identification of the deceased as well as the person involved is very much essential. Teeth and its associated structure help to achieve estimation of age, sex, race, reconstruction of facial anatomy, lip print, DNA fingerprinting, etc.
Conclusion: Forensic dentistry is the study and practice of different aspects of dentistry that are relevant to legal problems. Identification of a person from different dental records by a forensic dentist has been already established and accepted in court.

Objective: To determine the prevalence of hypertension among the patients attending dental out-patient department.
Introduction: Many patients seeking dental treatment and attending in Dental Clinic may not be healthy and may come with physical ailments like hypertension which may restrict his desired Dental procedures. Dentist may not be able to provide the treatment to prevent any untoward accident.
Material and methods: The present study was a hospital based cross sectional study conducted in a tertiary care centre during the period of January 2017 to March 2017.
Result: Analysis was done upon 98 dental outdoor patients to determine the prevalence of hypertension. The overall prevalence of hypertension was found to be 52% among the study group.
Conclusion: Before going for any dental procedure especially in elderly patients, a through clinical examination may lead to improved monitoring and treatment to the patients and it helps the doctor to avoid any untoward incident.
