Unbearable odour dampens spirit of devotees

Ujjain : With the sheer mismanagement on Simhastha Mela premises, the pilgrims are compelled to go through a dreadful experience as the unbearable odour fuming from the effluents leaking out of the septic tanks has made life hell across the fair. As the month-long Simhastha Mahakumbh is heading towards its culmination, scores of anomalies practised by the administration has surfaced. The biggest problem the pilgrims are going through is the odour spreading over the Mela area due to the effluents leaking out of the septic tanks built temporarily in the encampments and for the public use. Septic tanks built for the public toilets across the Mela premises are getting overflow with the large influx of devotees using the toilets. The Mela authority has failed to manage the things and hence the odour is causing great inconvenience to the visitors. As the final Shahi Snan is going to be held on May 21, enormous crowd is thronging to the Mela premises. People are compelled to defecate in open as the community toilets are not cleaned properly. Even the sewerage lines are broken at certain places which are posing a great problem to the visitors. The community toilet near Bharat Seva Ashram in Bhukhi Mata sector is the place where visitors are unable to use the toilets due to the mud and mire prevailed in its surrounding. The odour fuming out of the septic tanks has made life hell for the saints and their guests residing in the surrounding.

Protein that filters odour information

A 30 year-old mystery surrounding the function of a protein in our smell receptors has been solved after researchers revealed it plays a vital role in filtering data from smell receptors. The findings suggest that olfactory marker protein (OMP), a molecule found in the cells that detect odour molecules, plays a key role in regulating the speed and transmission of odour information to the brain. Led by researchers from the Monell Center, the study solves a three-decade-old mystery regarding the function of OMP, and increases understanding of how the olfactory system integrates information to transmit accurate data about odours and the messages they contain. "At any one time, thousands of different odour molecules arrive at the smell receptors in our noses to provide detailed information about the surrounding world. OMP helps the smell receptor cells filter this vast amount of information so that animals can respond appropriately," said Monell cellular physiologist Johannes Reisert, PhD, the study's senior author. Smell signalling Writing in the Journal of Neuroscience, the team explained that the process of converting the chemical information from an odour molecule into an electrical signal that can be transmitted to the brain is controlled by a complex sequence of molecular events called olfactory transduction. Although scientists previously knew that OMP had a role in this process, the exact nature of its role was unclear, until now. In the new study, Reisert and his team found that OMP – expressed in mature smell receptors known as olfactory receptor neurons (ORNs) – controls the level of signalling from receptors to the brain by filtering out base levels from ‘background noise’. In mice genetically engineered to lack OMP, the Monell researchers saw a resulting increase in base levels of cellular signals known as cAMP. This increase in base levels blocked differentiation between cellular signals from ‘background’ and a true stimulus. "What this tells us is that OMP dampens cAMP 'noise' to allow the olfactory system to differentiate between odorant receptors and to allow faithful transmission of odour information to the brain," said Reisert. "Understanding how olfactory marker protein and the odorant receptors dictate olfactory receptor neuron responses will help drive the direction of future studies to understand how ORNs contribute to our ability to experience and respond to our olfactory world," added Michele Dibattista, first author of the study.

Scientists say that body odour is manliness

MEN who want to appear more manly should consider how nice they smell, new research has found. Scientists at the University of Stirling say that applying deodorant can increase the perceived level of masculinity among men not usually counted as the most rugged among the population. However, this is not the case for those who already have high levels of masculinity, meaning that personal odour counts. The study, which investigated what effect wearing deodorant has on assessing masculinity and femininity, asked 130 female and male participants rate the traits using photographs while a further 239 men and women rated odour samples of 40 opposite sex individuals. The research found that women appear to be more sensitive or attentive to odour cues than males, and men rated low from their photos could increase their masculinity by applying a deodorant Dr Caroline Allen, Psychology researcher at the University of Stirling, who led the study, said: “Our study found that when women apply a deodorant it does increase their rated body odour femininity, as would be expected. "Though it seems as though something else is at play when it comes to male body odour and male deodorants. Only those men who were rated low in masculinity to start with showed a significant increase after applying their deodorants, and the men who were highly masculine initially showed no increase after deodorant application." She added: “This means that men are able to use deodorant to artificially raise their game so to speak, levelling the playing field by making themselves comparable, at least as far as odour is concerned, to more masculine men. "Our evolutionary preferences have likely shaped this difference in fragrance design: research findings show that we actually don't like high levels of masculinity which are often associated with aggressiveness and hostility, but we show no upper limit on our femininity preferences.”

hydrocarbon odour

Ideal for Hydrocarbon odours Anotec 0307 is the standard odour control, formulation. Efficacies of the formulation are determined via qualitative and quantitative techniques for odour measurement. Anotec 0307 formulations can be fogged, hand sprayed, misted or drip-fed depending on the application required. Anotec 0307 is fully miscible in water with scientifically chosen and blended surfactants. This blend, when applied via either a misting, fogging device or trigger sprayer bottle, alters the surface tension of the liquid/vapor compound. A key property of the Anotec 0307 formulation is that it modifies the surface properties of chemical odour components. The primary action takes place at the chemical odour and Anotec 0307 interface.

Brooklyn 'rotting carcass' odour unlawful

 by Ben Cameron

A Brooklyn meat rendering company that caused a ‘rotting carcass’ smell so bad it stopped nearby residents from inviting visitors to their homes was found guilty in court on Tuesday.

Australian Tallow Producers was found guilty of three counts of air pollution offences in the Melbourne Magistrates’ Court following an Environment Protection Authority Victoria investigation.

The company was found to have breached the Environment Protection Act 1970 after it polluted the atmosphere with odours offensive to humans on three separate occasions in June 2011 and September 2011.

ATP operates a rendering facility and manufactures tallow from mixed abattoir material on Geelong Road, Brooklyn.

On 22 June 2011, EPA received 13 complaints from nearby residents complaining about offensive odours coming from the site.

Complainants described the odour as a “smell like sewerage, like rotting carcass…”, a “very, very strong putrid dead animal smell…’’ which made one complainant say they felt like throwing up.

Another resident said they “had to lock all the doors and windows and could not have any fresh air in the house”.

The EPA received similar complaints the following day, and on September 21.

An EPA officer, who visited the area on 22 June 2011, reported a strong offensive odour comprising of a mixture of ‘manure, blood, bone and tallow’ coming from ATP’s premises.

Further visits by EPA officers on June 23, 2011 and September 21, 2011 confirmed the stench, with one officer reporting they “felt close to vomiting”.

The company will be sentenced on December 21, 2015.

EPA Chief Executive Officer, Nial Finegan said the EPA called on 11 witnesses, two expert witnesses and nine environment protection officers to give sworn evidence.

“The outcome is a win for the Brooklyn community who have had to put up with localised pollution issues for too long,” he said.

“No community should have to live with an odour so horrid that they can’t even have guests over, constantly feel nauseous and are forced to close their windows.”

The EPA had also issued ATP four pollution abatement notices since 2011 and were fined more than $7000 over an odour incident in 2013.
