Response of round goby (Neogobius melanostomus) to food odours

The well-established, invasive round goby (\u27Neogobius melanostomus\u27) is known to negatively impact native fish populations in the Great Lakes. My research examined whether food-based traps could capture round gobies which use chemical stimuli to find food and mates. My first experiment examined the response of round gobies in the laboratory and field to traps baited with lake whitefish, dreissenids, rainbow trout eggs and a control. Results showed that lake whitefish and dreissenids were preferred over other treatments in the field. Digestive tract analysis of captured gobies revealed that dreissenids were the dominant prey type. Subsequently, a laboratory experiment showed that round goby swam faster and spent more time near the odour source when exposed to soaked lake whitefish compared to other treatments, suggesting that lake whitefish could be used to capture non-reproductive fish. However, further studies are required to create a food baited trap to control the round goby

Change in the room temperature magnetic property of ZnO upon Mn doping

We present in this paper the changes in the room temperature magnetic property of ZnO on Mn doping prepared using solvo-thermal process. The zero field cooled (ZFC) and field cooled (FC) magnetisation of undoped ZnO showed bifurcation and magnetic hysteresis at room temperature. Upon Mn doping the magnetic hysteresis at room temperature and the bifurcation in ZFC-FC magnetization vanishes. The results seem to indicate that undoped ZnO is ferromagnetic while on the other hand the Mn doped ZnO is not a ferromagnetic system. We observe that on addition of Mn atoms the system shows antiferromagnetism with very giant magnetic moments.Comment: 5 figure

Water in the evolution of human civilization - The origin of life

Water is one of the natural resources that has enabled human life to evolve into a better life. The world cannot exist without water confirms this. It is clear that man got the surplus production with the help of water. The article sets out to show that the use of water has become the lifeblood of the nomadic nomadic life, and that the struggle for food has become a life-sustaining endeavor. The source of water is what sustains human existence. The primary source of life in harmony with nature is the discovery of aquatic habitat. The article sets out to explain that water is the source of life and that water is the source of human civilization

MEHENDIPUR BALAJI REVISITED: A DESCRIPTIVE PHENOMENOLOGICAL INQUIRY

The role of faith healing centers in the management of psychiatric conditions has become an integral part of psychotherapy in India. However, there are limited academic ventures trying to explain these practices via a psychological perspective. The present study aimed to explain the Mehendipur Balaji healing tradition by a qualitative exploratory study design using the tool of observation. Data was scrutinized through the strategy of qualitative narrative enquiry. Findings revealed the need of a psychological perspective in understanding faith healing practices along within the healthy accommodation of faith healing to mainstream psychotherapeutic practice.  Article visualizations
