Green synthesis of modified ceria nanoparticles and their catalytic activity studies
Catalysis is a phenomenon where a reaction is taken through an alternative pathway involving lesser energy. Thus, it has an energy saving dimension implicit in its definition. This thesis involves the study of catalysts, synthesized by the solution combustion method. The fuel required for the newlinecombustion is aqueous extract obtained from the leaves of selected plants which gives added credence to the ecofriendly aspirations that dominated our work. A series of ceria based nano sized catalyst materials, pure and modified using rare earth metal oxides, transition metal oxides and a non-metallic substance have been synthesized by the above method. The catalysts have then been newlinecharacterized for their composition, crystallinity, morphology, surface properties, thermal stability etc. The prepared catalysts were subsequently evaluated for their catalytic and photocatalytic efficacy. The photocatalytic potential of the catalysts was evaluated on the degradation studies of two dyes Malachite Green (MG) and Congo Red (CR) under visible light and one antibiotic drug ciprofloxacin (CIP) under UV light. The catalysts were found to show good photocatalytic efficiency newlineon all the three substances mentioned above. The catalytic efficiency was evaluated on two chemical reactions. One, the reduction of 4-nitrophenol to 4-aminophenol and the other, the synthesis of compounds of Biginelli reaction. To achieve maximum reduction the experimental conditions for the catalyst were newlineoptimized. Biginelli reaction involves the condensation of ethyl acetoacetate, newlinebenzaldehyde and urea in presence of modified ceria catalysts to form dihydropyrimidines. The reaction was performed with different catalysts and the one which gave the best yield was selected for further optimization of other reaction conditions. Employing the optimized conditions, a set of different newlinedihydropyrimidinone derivatives were synthesized by varying the precursor newlinealdehydes and ketones. Reusability studies for the catalysts were conducted for all the reactions mentioned above. -

Sentencing Framework in the Administration of Criminal Justice in India :
This Thesis aims at having uniformity while sentencing the accused in respect of similar newlineoffences by various criminal courts. It is submitted that, in India, there is no separate sentencing Act which provides for the sentencing of the accused. It is submitted that the present thesis also recommends for the post sentencing/research process and administration of Criminal Justice through courts and supervisory power of the court over the executive after newlinethe conviction of the accused and during the pre-trial detention. Emphasis is also laid on newlineBails Act which is required to be legislated in the administration of Criminal Justice in India. The said Bails Act and Sentencing Act are very much in force in different common law countries such as New Zealand, UK, and USA. Similar legislations are the need of hour in the present day for administration of Criminal justice in India. The thesis also aims at highlighting the disparity of Sentencing by the different Criminal Courts in India. There are instances where length of detention itself is held to be sufficient, mitigating grounds are taken into consideration, and the accused is being given set-off for the period that he has already newlineundergone. The administration of post-sentencing process, more particularly probation is also being highlighted. The need for probation is also being highlighted, so also the requirement of plea bargaining being more popularised. The grant of parole by the executive in ignorance of conviction order is also critically analysed. Reforms are suggested for the better administration of criminal justice with special reference to sentencing. -

Understanding magic realism in regional cinema: A content analysis of selected Malayalam films /
Magic Realism, was introduced in Latin America as an expression of the blend of realist and magical views of life in the perspective of the conflicting cultures of Latin America expressed through its art and literature, but later it was adopted as a term used to refer to all narrative fiction that includes magical events in a realistic matter-of-fact narrative, where, the unordinary or supernatural is not a plain or evident matter, but it is an ordinary matter, which can happen every day. -
Towards reading song in performance as aural narrative : Reading a sense of spatiality in select albums of mark knopfler using henri lefebver's notions of space
One of the chief objectives of this study is to explore and offer a strategy to read song in performance as Aural Narratives. This was necessary because verbal texts can be read in multiple ways. Perhaps the chief claim of a text s possibility to be literary lies in its inherent potential to be discursive. Therefore sound texts require a way of understanding sound as an element of storytelling. Shifts in Humanities necessitate an expanding notion of textuality. One of the chief concerns and burdens of the writer of literature is the evocation of a sense of spatiality which can be perceived as an outcome of spatial practice. Spatial practice in turn is defined by social codes and practices. Spaces can be read therefore through the life experiences of the inhabitants of a space as spatial practices are dependent on particular spaces. This study explores the use of Sound in creating a sense of Spatiality. Singer, songwriter and guitarist, Mark Knopfler creates songs that are arranged around a central character s lived experience. Thus the perception and conception of a sense of space that is thus evoked can be negotiated using Henri Lefebvre s triadic notions of newlinespatiality as a reading strategy. -
Credibility of advertisements on social media - people's perspective /
Social media has created a buzz ever since its inception. It has always created the curiosity factor amongst the people. There has been numerous literatures and information regarding social media and its influence on people, but the most important aspect is the bond that people seem to have developed with social media today. Considering the dependability of the audience on social media, the credibility factor has to be strictly monitored. -
Non-Invasive Early and Precise Detection of Breast Tumor with Novel UWB Radar Pulse
Impulse Radio Ultra-Wideband is emerging as a superior breast cancer detection technique compared to ultrasound, magnetic resonance newlineimaging and X-ray mammography due to its high resolution, nonionizing radiation, effectiveness in dense tissues and cost-effectiveness. Radar-based Ultra-Wideband technology is a viable, non-invasive newlinetechnique for detecting breast cancer. The Ultra-Wideband signal must be safe to penetrate deep into human breast with minimal attenuation and comply with Federal Communication Commission regulations to newlineensure early, precise detection of deep-rooted malignant tumor inside newlineheterogeneous breast. In this research work, a shaped Ultra-Wideband Gaussian pulse of newlineseventh order is employed in a radar-based breast cancer detection system. A sharp transition bandpass Finite Impulse Response filter is designed in this work for safe, deep penetration and optimal transmission through the heterogeneous breast. The pulse shaper filter design has a sharp transition with a low side lobe level and can be tuned newlineto any variable center frequency. This design is suitable for shaping very short-duration pulses, achieving higher data rate and less newlineinterference issues. Also, the pulse tightly fits the Federal Communication Commission spectral mask, thus achieving higher spectral utilization efficiency and meets the signal safety standards for transmission through the breast. The shaped pulse fed to the antenna of the radar system provides higher antenna radiation efficiency and radiating power due to the concentration of power in the main lobe. This research work employs bistatic and monostatic radar systems to detect the deep-rooted and smallest formation of the malignant tumor in the breast. Tumor detection is based on the time and frequency newlinedomain analysis of the backscattered signals from the malignant tumor. These signals have higher amplitude, higher electric field intensity variations and an increase in the scattering parameter values due to the newlinepresence of tumor. -
School Counseling in India : School Counselor Roles, Policy and Implementation
With a lack of comprehensive policy and literature on stakeholders perspectives and the counseling program s implementation, there is much to be known about the present status of school counseling in India. Three research questions examined in two phases were the perception of actual and preferred roles of the school counselors from the perspective of school administrators, school counselors, teachers, students, and parents; awareness and implementation of school counseling policy from the perspective of administrator and counselors; and implementation of the school counseling program. Quantitative phase I met newlineobjectives one and two using cluster sampling to select 1029 participants. School newlineadministrators and counselors completed the Survey on Knowledge and Implementation of newlinePolicies Regarding School Counseling which was developed and validated by two experts in newlinethe study. All participants completed the International Survey of School Counselor Activities (ISSCA) (Fan et al., 2018). Statistical analysis included descriptive statistics, the KruskalWallis H test, and post-hoc Bonferroni-Dunn. Qualitative phase II met objective three using purposive sampling to recruit 14 participants for a semi-structured interview. Qualitative newlinecontent analysis indicated that school counseling in India is still developing, with newlineinconsistencies in understanding the counselor s role among stakeholders. There were differences in awareness and knowledge about the responsibility of implementing school counseling policies. School counseling programs were affected by role ambiguity, stigma about mental health issues, lack of comprehensive structure to the counseling program, and lack of research and evaluation. Implications of the study are discussed. -
A study on the portrayal of women characters in Zoya Aktar's films /
Leaving behind the social fabric which has time and again labelled Indian women merely as good wives, home makers and mothers , Indian women took it in their stride to take up the duties which are essentially thought of being male only, and proved that they are equal to their male counterparts; if not better in some cases. -
Representation of print media in films /
This research is a study on Representation of print media in films. Creating awareness about the representation is one of the objectives of the study. Before forming an opinion about the representation of print media in films it is important to know what those representations represent. Today there are online newspapers and it co-exists with the traditional print media. Thus the researcher has found it more important to study the portrayal of the print media in films in the context of todays time and space. The researcher is not trying to appeal that print media should be potrayed in a certain way. The research contains analysis some films to study the representation. Researcher is not being judgemental about the representations but only investigating what is the depiction of print media, journalists and professions in films as films are a different medium from print. -

Identifying 'Self' Through Society : A Socio-Psychological Perspective of A Song of Ice and Fire
The Socio-Psychological Character Analysis Model (SPCAM) is developed to analyse complex literary characters. It helps readers of Literature understand the characters psyche and behaviour by keeping in mind their social background and influences. To develop the literary model, SPCAM, concepts from two theories are synthesised, which are Symbolic Interactionism (SI) and Cognitive newlineBehavioural Theory (CBT). The common threads between the two theories weave them together, and the complementary threads strengthen the developed model. SPCAM studies how characters make meaning while interacting with themselves and others in the society, while also identifying and evaluating their thoughts and beliefs. Using SPCAM helps the user to systematically extract necessary data newlinefrom the text, tabulate it according to the parameters set by the model, and examine the character s internal and external factors, as provided in the text, leading to a comprehensive review of the character and a character conceptualisation. SPCAM helps the users to substantiate their claims about a newlinecomplex character by helping them be more methodical and thorough. The introductory chapter establishes the need and scope of the research. It reviews the benefits of collaborating with Social Psychology for a literary analysis. After which, it defines the theories merged to build the model. The newlinedeveloped model, SPCAM is then explained in detail. This is followed by the rationale for using fantasy fiction, a brief about the author, George R.R. -
Antecedents of Behavioural Intention : Study of Indian Consumer Perceptions Towards P2P Lending Using Technology Adoption Model
Fintech is a rapidly developing area of the financial services business where tech-focused startups and other new players are upending how the sector has historically operated. One of the emerging fintech areas under digital lending is Peer to Peer lending or (P2P) lending; Consumers and authorities are both showing interest in this alternative lending innovation. Results of a literature review show that India is still in the early stages of P2P lending research. The study examines the association between behavioural intention to use P2P lending in India and technological and personal adoption factors. The study model was developed with the help of a literature review and tested using data from 536 respondents who completed an online survey and was tested using covariance-based structural equation modelling (SEM). The results confirm that personal innovativeness, performance expectancy, hedonic motivation, effort expectancy, social influence, and perceived risk are the antecedents of the adoption of P2P lending, except for facilitating conditions and price value. In addition, gender moderates the relationship between performance expectancy, hedonic motivation, personal innovativeness, and intention to adopt P2P lending. The study also throws light on the perceptions of both users and non users in terms of the antecedents. The study's conclusions significantly impact the P2P lending industry and provide practical insights for developers, platforms and regulators to improve and enhance the service. The study suggests looking at other moderating factors like age, voluntariness, experience, and actual usage behaviour for further research. Overall, the research contributes to the academic literature by confirming the predictive power of the extended unified theory of acceptance and use of technology (UTAUT). It highlights personal innovativeness after performance expectancy and motivation as an important factor in predicting the usage of P2P lending. Finally, the study lists managerial implications in the domains of technological adoption, which will assist in the P2P lending long-term success in India. -

A Study on Labeling Problems in Signed Graphs
A signed graph can be considered as a weighted graph G; that is, edges of G have been given the weights + and and#8722;. We discuss two ways to assign signs to the vertices of a line signed graph of a signed graph, namely S-marking and Canonical marking (C-marking) of L(S). We characterize signed graphs whose line signed graphs are S-cordial or total S-cordial provided the vertices of L(S) receive signs through S-marking. Also, we characterize signed graphs whose line signed graphs are C-cordial or total C-cordial provided the vertices of L(S) receive signs through C-marking. Signed graphs can be eand#64256;ectively used to model relationships and individual preferences toward one another. To represent this scenario we defne a signed graph from a given graph. The colors of the vertices can be used to represent individuals or sets, and the signs on the edges of the graph represent the relationship between them. So, we defne two labelings of a properly colored graph, namely parity labeling of a properly colored graph and product labeling of a properly colored graph. newlineThe parity labeling of a properly colored graph G under and#967;(G) colors is defned by assigning the sign of the edge of G as + if the colors on the adjacent vertices of that edge are both even or both odd, and#8722; otherwise. The obtained signed graph is known as parity colored signed graph of a graph. We characterize signed graphs which admit parity coloring. We also characterized signed graphs whose line signed graphs admit parity coloring. We initiate the study on parity labeling of a properly colored graph and the chromatic rna number of a graph. Also, we defne product labeling of a properly colored graph. The product labeling of a properly colored graph G under and#967;(G) colors is defned by assigning the sign of the edge of G as + if the color of one of the incident vertex of that edge is even, and#8722; otherwise. The obtained signed graph is known as color product signed graph of a graph. We characterize signed graphs which admit color product coloring.
