Impact Identification and Determinants of Gambling: A Case of Figure Gambling in Sholapur
No full textThe study is an attempt to identify various determinants, viz., income, consumption, age, education and sex of figure gambling. The activity which is considered to be illegal by the government of many countries is widely practiced in Sholapur district of Maharashtra. The current study adopts a mixed-method research design to examine the motivation for gambling and its impact on developmental indicators. Results show that the variables like income, education, sex, consumption and age are having relationship with gambling and its frequency. Although the values of correlation coefficients are very small, except in case of education and sex, yet the analysis shows some sort of relationships between these variables and gambling frequency.
Parsec-scale structure of quasars: dawn of the golden age?
No full textHalf a century after their discovery, the study of quasars remains one of the most fascinating intellectual challenges in astronomy. Quasars are laboratories for everything from relativity to magnetohydrodynamics and are perhaps the best available probes for cosmology. A tremendous amount has been learned about quasars and yet many of the most fundamental questions about their physics remain open. Parsec-scale observations have played an indispensable role in building up our current understanding of quasars; virtually everything we know about quasars depends on such observations. However, the finest hour for parsec scale observations may be just beginning. This is partly due to the development of highly reliable VLBI networks (which is continuing) but mostly due to the unprecedented availability of multiepoch, simultaneous, broadband observations that have long been the `holy grail' for quasar researchers.The author gratefully acknowledges his colleagues in the TANAMI and Fermi/LAT programs from whom he continues to learn.

From Radio with Love: an overview of the role of radio observations in understanding high-energy emission from active galaxies
No full textThe gamma-ray satellite Fermi and the ground based TeV facilities MAGIC, VERITAS and HESS have ushered in a new era in the observation of high-energy emission from active galaxies. The energy budgets of these objects have a major contribution from gamma-rays and it is simply not possible to understand their physics without high-energy observations. Though the exact mechanisms for high-energy production in galaxies remains an open question, gamma-rays typically result from interactions between high-energy particles. Via different interactions these same particles can produce radio emission. Thus the non-thermal nature of gamma-ray emission practically guarantees that high-energy emitters are also radio loud. Aside from their obvious role as a component of multiwavelength analysis, radio observations provide two crucial elements essential to understanding the source structure and physical processes of high-energy emitters: very high timing resolution and very high spatial resolution. A brief overview of the unique role played by radio observations in unraveling the mysteries of the high energy Universe is presented here.The author thanks Matthias Kadler for numerous very helpful discussions.

Simulation of Forward Osmosis Using CFD
No full textAbstractIf fresh water and salt water are separated by a membrane, the fresh water would flow across the membrane from fresh water chamber to salt water chamber in a forward osmosis process. Forward osmosis and reverse osmosis processes have been used for many new applications like wastewater treatment, food processing industry, and desalination of seawater. Computational Fluid Dynamics (CFD) software, viz., FLUENT software is used for simulating FO process. The water moved across the membrane from fresh water side to salt water chamber indicating that FO was well represented by FLUENT
Method for Generation of Pendant Drops Through Localized Condensation for Contact Angle Measurements in Conditions Deviating from Standard Environment
Get PDFabstract: Contact angle goniometer is one of the most common tools in surfaces science. Since the introduction of this instrument by Fox and Zisman1 in 1950, dispensing the liquid using a syringe has generated pendant drops. However, using such approach at conditions significantly deviating from standard pressure and temperature would require an elaborate and costly fluidic system. To this end, this thesis work introduces alternative design of a goniometer capable of contact angle measurement at wide pressure and temperature range. In this design, pendant droplets are not dispensed through a pipette but are generated through localized condensation on a tip of a preferentially cooled small metal wire encapsulated within a thick thermal insulator layer. This thesis work covers experimental study of the relation between the geometry of the condensation-based pendant drop generator geometry and subcooling, and growth rate of drops of representative high (water) and low (pentane) surface tension liquids. Several routes that the generated pendant drops can be used to measure static and dynamic contact angles of the two liquids on common substrates well as nanoengineered superhydrophobic and omniphobic surfaces are demonstrated.Dissertation/ThesisMasters Thesis Mechanical Engineering 201
Picture versus words: A comparison of pictorial and verbal informed assent formats
No full textBackground for the Study: Informed consent is a process of obtaining permission from the participant to participate in research. Involving children in a research requires them to give their “assent” for participation. Informed assent is obtained from children even after their guardians have given consent for participation. Studies have shown that children have difficulty understanding the key elements of research process such as right to withdraw from the study or the meaning of “harm” involved in the research process. Further, the studies have also propounded that using child-friendly methods such as using pictures and simple language would facilitate children's understanding. Objectives: In this study, pictorial and verbal assent formats were compared find out which format is suitable for children's understanding of informed assent with respect to research. Methods: A sample of 389 school going children and adolescents of both the gender, ranging from 7 to 16 years were considered for the study. The sample was randomly divided into two groups, where for one group (n = 197), pictorial assent format was administered and another group (n = 192), verbal assent format was administered. The pictorial assent format was developed for the study by the corresponding author. Results and Conclusions: Analysis revealed that there was a significant level of interaction between gender and the two assent formats. Males were able to understand pictorial assent format better compared to the females, whereas females were able to understand verbal assent format better than the males, when age and education were considered as covariates. Further, it was found that as age increases there is better understanding of research processes in both the formats. Hence, while the process of obtaining assent for participation in research, age of child must be considered and with respect to gender differences males tend to prefer pictorial formats whereas females tend to prefer verbal formats
Impact of Institutions in Managing Rural Water Resources: Identifying Appropriate Institutional Framework in a Semi-Arid Region of Rajasthan
No full textWater acts as an important component in sustaining rural livelihood. In a semi-arid region like Alwar district of Rajasthan water management is inevitable for rural livelihood. Effective water management depends upon appropriate institutional framework viz., tripartite and bipartite institutional framework. Community participation is indispensable for making any project successful. Tripartite institutional framework comprises community, NGO and international funding agency. On the other hand, bipartite institutional framework comprises of government and panchayat. The work attempts to identify an appropriate institutional framework, in enhancing rural sustainability. It further attempts to examine the impact of institution i.e., participation and income on rural sustainability. The results of t-statistics showed significant mean difference between the performance of bi-partite and tri-partite institutional framework. In order to examine institutional impact, socio-economic impact assessment approach has been used. Tobit estimates show that participation and income level are having significant and positive impact on different sustainability indexes
