Study of the toxicity of two pharmaceuticals on invertebrate Hydra Vulgaris and observing effects on morphology and physiology

The Cnidarian Hydra has been extensively used as a model organism studying the teratogenic and toxic potential of numerous toxins throughout the years and are more recently growing in popularity to assess the impacts of environmental pollutants. Hydra is an appropriate bioindicator species for use in environmental assessment owing to their easily measurable physical (morphology), biochemical (xenobiotic biotransformation; oxidative stress), behavioural (feeding) and reproductive (sexual and asexual) endpoints. Pharmaceuticals enter natural waters through sewage effluent and landfills and present an unknown risk to aquatic species including freshwater invertebrates. The cnidarian Hydra has been widely used to assess the acute toxicity of freshwater pollutants, but very little is known about pollutant accumulation by this animal. This study was conducted to study the effect of commonly used drugs, Paracetamol and Acetylsalicylic acid (Aspirin) on the morphological and physiological working of Hydra Vulgaris. The Hydra was exposed to 4 different concentrations of each drug for 24 hours and then observed for morphological and physiological changes.

Development and shelf-life studies of pea enriched gluten free cookies

Millets are gluten free and excellent for celiac disease patients. An attempt was made to develop pea incorporated millet cookies. The developed cookies were analyzed for physical parameters like weight, thickness, and diameter, spread ratio, percent spread and bulk density. The cookies were analyzed for proximate composition, mineral content, anti-nutrients and anti-oxidants. The products were packed in polyethylene pouches and stored at ambient temperature for 4months and analyzed for microbial and consumer acceptability. On storage there was increase in the moisture content of the samples from 4.65% to 6.25% and decrement in anti-nutrient and anti-oxidant content. Addition of 30% pea flour to composite flour was found acceptable by considering the overall quality of the developed cookies and the economic aspect

Modelling and structural analysis of double bubble fuselage for optimal payload capacity

This paper describes the model III Modelling and Analysis of the Double Bubble (DB) fuselage at different pressure loads condition. The computer analysis includes the computation of circumferential stress, total deformation, maximum stresses. The advantage of DB fuselage is to increase the payload carrying capacity and contributes towards the increase of lift. The modelling of the fuselage has been carried out with different configurations so as to minimize the total deformation. There is the research compulsion to modify the existing fuselage geometry to accommodate more number of passengers with less cost. This project optimizes the design using SOLIDWORKS latest version. The in-depth analysis have been carried using ANSYS R18.1 version. Three models has been created and compared for optimized characteristic parameters. This project fulfills the gap between the passengers comfort and airlines economy. The computations of three models give a converging results. Model III has almost elliptical geometry which obtained by the DB concept and it has the least computational result values. The model III provides more seating space for the passengers.

Effect of Hydroxy (HHO) gas addition on the air-fuel ratio, mileage and fuel consumption of a motorbike equipped with 4 stroke SI engine through theoretical calculations

This research aims to compare the mileage and fuel consumption of a BAJAJ Pulsar 150 equipped with a 4 stroke SI Engine with and without the assistance of Hydroxy (HHO) gas through theoretical calculations and derive suitable conclusions. HHO gas consists or Hydrogen (H2) and Oxygen (O2) which are liberated during water electrolysis. The hydrogen gas produced by electrolysis of water is injected through a small opening in the engine intake manifold while the carburettor, fuel pipeline, and engine cylinder being unaltered. Topics from elementary Chemistry, Engineering Thermodynamics and IC Engines were used in the calculations. The specifications of SI Engine used in the Bajaj Pulsar 150 were also taken into account. The following results were obtained from the calculations when the engine was run with the aid of HHO gas: (a) 4.54% increase in mileage of the bike when operating the engine under maximum power condition. (b) 4.71% increase in mileage of the bike when operating the engine under maximum torque condition. (c) 74.2% decrease in fuel consumption, (d) No change in Air-Fuel(A/F) ratio

The thrust generated by DIY Ion Thruster

Nowadays, Electronic propulsion is the most used technology for controlling the precise motion of the satellites or explorers. As a Physics enthusiast, I wanted to experiment with the Electronic propulsion engine and calculate the thrust generated with the small electronic propulsion engine at atmospheric conditions near sea level. In this experiment, we made a small setup of ion thruster, which can generate very small thrust; we also tried to explain the mathematical model of the thrusts of such designs.

Study of the relationship between humour, stress and psychological well-being in young adults

This study is titled as “Relationship between humour, stress and psychological well-being in young adults.” The objective is to study the relationship between humour and stress, humour and psychological well-being and stress and psychological well-being among young adults in Pune city. The total sample of 139 consisted of college students who are currently enrolled in a professional or a traditional course. The methodology consisted of purposive sampling. Standardized tools of Multidimensional Sense of Humour Scale, Perceived Stress Scale and Scales of Psychological Well-being were used for data collection in order to assess humour, stress and psychological well-being respectively. The Parametric measure of Pearson product-moment correlation was used to analyse the data, followed by regression. The results revealed a significant positive correlation between Humour and Psychological Well-being (significant at 0.01 level), and a significant negative correlation between Stress and Psychological Well-being (significant at 0.01 level). The implications could be that adaptation of humour in teaching methods will create a relaxing environment. This can facilitate student participation, concentration, attention, as well as can strengthen and increase social interaction.
