Effect of manipulated environmental condition on the distribution of Aero-algal Counts
Reports on occurrence, distribution pattern, listing of aero-algal forms, seasonal calendar, allergenic aero-algal forms, effect of meteorological parameters on occurrence of aero-algal forms etc. has been reported by number of aerophycologists. But solution on reducing such aero-algal counts which can be a possible cause for allergenic reaction has not been suggested until known. Hence preliminary study with respect to effect of manipulated environmental condition on the distribution of aero-algal counts has been done. Presence of cooling tower results into manipulation of the climatic factors, such as temperature and humidity percentage. The high humidity percentage act as an unfavorable condition for the surviving of aero-algal forms resulting into sporulation. This spores required some incubation period under favourable condition to undergo for its vegetative development. This knowledge can be used as a possible solution for the allergenic patients. Manipulation of climatic factors can be done both at intramural as well as extramural sites by using water coolers, A.C, introducing water falls etc. It can be considered as possible manageable solution for patient suffering from allergy due to aero-biological pollutants

Mapping of axial plastic zone for roller bearing overloads using neutron transmission imaging
Premature failure of wind turbine gearbox bearings is an ongoing concern for industry, with sudden overload events potentially contributing towards raceway damage, significantly hindering performance. Subsurface stresses generated along a line contact cause material yielding, and a probable crack initiation site. Currently, the ability to study subsurface plastic zone evolution using non-destructive techniques is limited. Neutron Bragg edge imaging is a novel technique, allowing for two-dimensional mapping of the Bragg edge broadening parameter, indicative of bulk plastic deformation. An experiment on the ENGIN-X strain scanning instrument, at the ISIS neutron source, UK, was setup for Bragg edge transmission imaging, to measure the effect of in situ loading on the raceway of a bearing, scaled-down from a traditional wind turbine gearbox bearing. Results demonstrate a strong correlation between load and the Bragg edge width, and allow for future experimental development in studying, not only the effect of overloads on fatigue life, but also the use of neutron imaging for evaluating plastic deformation in engineering components
Predicting Externally Visible Traits from a DNA Sample for Law Enforcement Applications
A large majority of crimes such as homicides, sexual assaults and missing person cases are not solved within a reasonable timeframe and become cold cases. The ability to predict visual appearance and ancestry from a DNA sample will provide an unprecedented advancement in such criminal investigations. DNA based prediction of craniofacial features, phenotypes and ancestry can be used to reduce the pool of candidates onto which to perform further investigations. To achieve the above goal, it is first essential to substantiate, model and measure the intrinsic relationship between the genomic markers and phenotypic features. The first step is to standardize the 3D face scans using the CoMA data format followed by its projection into a low- dimensional latent embedding space. The second step is to reduce the dimensionality of the genetic space by performing Principal Component Analysis on the genomic markers to generate compact genomic properties. A simple multi-layer perceptron is trained to classify an ensemble of facial embeddings and genomic properties into genuine and imposter pairings. The classification model is able to match the DNA with the given 3D face with an average AUC score of 0.73. The introduction of hand-picked genomic markers serves to be an important contribution towards improving the final AUC score. Furthermore, results indicate that incorporating additional phenotypical properties such as sex and age leads to a better verification. Thus, this study proves to be an important milestone towards identifying suspects from their DNA sample in a criminal investigation
Report on aero-algal form from Konkan coastal area
There are very few reports on the occurrence of aero algal forms near coastal area. Konkan beaches in coastal Maharashtra are famous as hot tourist spots, visited by nearly few thousand visitors per year. This is the first aero algal report from a Guhagar beach. Sample was collected using fan as sampler (Jogita. T. Pandkar, 2011) from a residential bunglow (Mody villa) situated near Guhagar beach. Total 12 algal forms were recorded from a single sample collected within 10 days, indicating towards the effective use of fan as a sampler. Cyanophyta was found to be dominant group followed by Chlorophyta. Out of 12 algal forms recorded, 09 were identified upto generic level and 05 forms were identified upto species level. Various cyanophycean forms recorded were Chroococcus, Nostoc, Phormidium, Microcoleus & Microcystis. Chlorophycean forms recorded were Chlorella & Spirogyra respectively. Forms such as Chlorella, Microcystis & Phormidium known to be allergenic to human beings have been encountered, indicating the presence of potential allergents in the air.</jats:p
