IRRELEVANCE OF ITEM NUMBERS IN BOLLYWOOD MOVIES TODAY- AFFECTING THE PORTRAYAL OF ITEM GIRLS
The research paper was aimed to look into the portrayal of women in media especially those who do item numbers. The paper also looked into the matter that how due to the lack of relevance of item numbers in movies today, the portrayal is negative. Whether this in turn has led to a negative stereotypical representation of women in general was also a concern of the study. The researcher focussed on this matter as she is strongly against any kind of stereotypical representations. As a media student she wanted to inform people about the rights and wrongs in the society and how this leads to framing of stereotypes which is often regarded derogatory. The research was done using both primary and secondary sources. Primary data collection included questionnaire method to general audience of sample size of 100 and a comparative analysis will be done. An extensive study was done of secondary sources too including books, journals, movies, short videos, internet and newspapers. The study revealed that item numbers have definietely lost its relevance in the movies and that has led to the negative portrayal of item girls. There were other reasons also found have an impact on the audiences?? mind which in turn influences his thinking towards the item girls, this was found by comprehending the study with Cultivation theory by Gerbner. -
Isolation of Fungal Endophytes From Hulimavu Lake Flora and Characterization and Optimization of Fungal Enzymes
The present work was aimed at isolating fungal endophytes from Hulimavu Lake, newlineextracting their secondary metabolites and fungal enzymes to subsequently probe the newlinebiological properties of these fungal endophytic bioactive compounds and enzymes. newlineHulimavu Lake, known for its notoriously high levels of pollution contributed by newlineanthropogenic factors, was chosen for this study with the literature-evidence backed newlinehypothesis that plant habitat stress also positively favors the type and quanta of bioactive compounds with novel features produced by its endophytes. Literature survey was performed to identify the probable types of plants found in this lake that could be used for the study and these were subsequently collected, identified and processed under laboratory conditions. These plants were authenticated by a certified botanist and were identified as Alternanthera philoxeroides, Ricinus communis and Persicaria glabra. Fungal endophytes were then isolated from different plant parts collected and were screened using preliminary LCB staining followed by DNA sequencing analysis. Based on ITS region sequencing, nucleotide homology and phylogenetic tree mapping, these fungal endophytic cultures were identified as Aspergillus niger, Talaromyces amestolkiae, Cladosporium phaseolorum and Diaporthe phaseolorum. Crude extracts obtained from these fungal endophytes displayed bacterial growth inhibition and significant free radical scavenging/ reduction potential that was comparable to standard ascorbic acid, hence depicting antioxidant activity of these extracts. Owing to their biological properties these crude extracts were further tested for cytotoxic properties on newlinedifferent models like that of Saccharomyces cerevisiae (Baker s yeast), Artemia salina newline(Brine shrimp) and MCF-7 cell line. The presence of fungal endophytic enzymes like newlineprotease, amylase, laccase and lipase was detected qualitatively and estimated newlinequantitatively. -
Isolation, Characterization and Evaluation of Potential Plant Growth-Promoting Bacteria From The Rhizosphere of Coffea arabica L. From Kodagu District, Karnataka
Agriculture is fundamental to food security and economic stability. The utilisation of newlineplant growth-promoting rhizobacteria (PGPR) an eco-friendly alternative to chemical newlinefertilisers is particularly promising as these microorganisms enhance nutrient newlineavailability, stimulate plant growth, and improve resistance to biotic and abiotic newlinestresses. This study aimed to isolate and characterise PGPR from the rhizosphere of newlineCoffea arabica L. in the Kodagu District of Karnataka, focusing on their potential as newlinebiofertilizers. Soil samples collected from ten different locations within Kamath Coffee newlineEstate led to the isolation of fourteen distinct bacterial colonies, labelled NJ01 to NJ14. These isolates were evaluated for various plant growth-promoting (PGP) traits like indole-3-acetic acid (IAA) siderophore and ammonia production, nitrogen fixation, newlinephosphate, and zinc solubilization and hydrogen cyanide (HCN) production. Further newlinestudies were carried out using 3 isolates with significant PGP traits. Enzyme activity newlineassays indicated that NJ01, NJ04, and NJ14 had positive results for protease, cellulase, newlineamylase, and catalase activity. These strains also displayed varying degrees of newlinehalotolerance, with NJ01, NJ04 and NJ14 tolerating up to 8%, 10% and 11% NaCl, newlinerespectively. Heavy metal tolerance tests revealed that NJ01 tolerated Pb up to 250 newlineg/mL, NJ04 tolerated Pb up to 1500 g/mL and Cd up to 50 g/mL, and NJ14 tolerated Pb up to 1000 g/mL and Hg up to 100 g/mL. Polyhydroxyalkanoate (PHA) production was confirmed in all isolates, with NJ01 yielding the highest amount (6.4 g/L). The isolates exhibited significant antifungal and the 16S rRNA sequencing identified NJ01 as Bacillus albus (OP784795), NJ04 as Bacillus licheniformis (OM780221), and NJ14 as Bacillus subtilis (OM780222). A consortium was prepared after confirming the plant growth promoting abilities of these PGPR strains by carrying out an initial plant growth studies. The optimisation of media parameters was by using a two-factor interaction model. -
Isolation, Identification and Characterization of A Potential Probiotic Bacteria and its Application in Aquaculture
In the current study, Bacillus subtilis PKB1 was isolated from dried anchovies and identified using morphological and biochemical analysis followed by 16S rRNA sequencing and phylogenetic analysis. The antibacterial and anti- haemolytic properties of the bacteria were also examined. Probiotic qualities were assessed by measuring the isolated strain's tolerance to artificial gastric juice. To assess the isolated strain's capacity for stress tolerance, additional exposure to varied pH, temperature, and organic solvent concentrations was given. Bacillus subtilis in MRS medium produced exopolysaccharide (EPS) which was purified and a maximum yield of 1928mg/L was achieved. The novel exopolysaccharide was purified and characterized to be a heteropolysaccharide. The polysaccharide present had a molecular weight of about 20 kDa overall. FTIR spectroscopy revealed the presence of carboxyl, hydroxyl, and methylene groups in the EPS. The extremely cross-linked structure of the EPS with lumps that resembled spikes was revealed by atomic force microscopy. Scanning Electron Microscopy (SEM) revealed that it possessed rough, asymmetrical lumps. Emulsification activity was also observed in the EPS. The current study's findings suggested that this EPS might make a good candidate for further applications. Utilizing probiotics derived from unconventional sources may improve the variety of probiotics accessible for use in aquaculture procedures. Probiotics are used in the field of aquaculture in order to improve immunity and to protect against pathogenic microbes. Species such as Aeromonas hydrophila and Vibrio parahaemolyticus are responsible for increasing mortality, decreasing production efficiency and forcing antibiotic overuse. In this study, the role of the isolated probiotic in promoting growth performance in Nile tilapia was examined using growth and challenge studies. The experiment was conducted for a duration of 30 days. Weight gain, histology and mortality rates were studied in the presence and absence of pathogenic microbes. Bacillus subtillis PKB1 supplementation for Nile tilapia helped to maintain the integrity of gill filaments and improved survivability and weight gain when used at a concentration of 1x104 CFU/ml. The study showed that the isolate improved the survival rate of Nile Tilapia against Vibrio parahaemolyticus and Aeromonas hydrophila. -

K shell Radiative and Total Vacancy Transfer Probabilities of Barium & Thallium from Internal Conversion Electron Sources
The information obtained from X-ray fluorescence parameters is very important in the study of some basic phenomena, in atomic molecular and radiation physics. This demands for accurate values of XRF parameters such as shell wise and sub-shell wise X-ray fluorescence yield, fluorescence X-ray production cross-section, shell and sub-shell intensity ratios, K to L vacancy transfer probabilities and so on. Nuclear processes like orbital electron capture or internal conversion of gamma transition and interaction of photons or charged particles give rise to X-ray fluorescence. It is reported that the probability of emission of X-rays by decay process is different from the probability of emission of X-rays by photoionisation[1-3]. The K shell XRF parameters of elements have been extensively studied by several researchers by photon exciation methods and varieties of detectors [4-9]. But there are not many reports on the measurements of K shell X-ray intensity ratios of elements following decay processes. This may be due to the requirement of the radioactive sources of the order of 100mCi and preparing many electron capture and internal conversion sources of this strength may be a difficult task. In view of this, we have made an attempt to study the effect of internal conversion on the probability of X-ray emission of thallium and barium by determining K shell intensity ratios, K ?? Li, K-M radiative and K-L total vacancy transfer probabilities from weak internal conversion sources Hg203 and Cs137respectively. To examine the effect of decay process on X-ray emission the K shell fluorescence parameters determined are compared with the theoretical values and other experimental results obtained using radioactive decay and photon excitation methods. The dissertation consists of five Chapters. In the first Chapter, we introduce the project work carried out. In Chapter 2, we present the brief theory of XRF and literature survey. It consists of two sections; in section 2.1, we give the theoretical aspects of the K X-ray fluorescence and in section 2.2, we present the literature survey related to the determination of K X-ray intensity ratios and vacancy transfer probabilities through photoionization methods and decay processes. Chapter 3 deals with experimental details such as the radioactive sources, detector and electronic modules used in our experiment, the experimental arrangement and standardization of spectrometer, and experimental procedure adopted in the collection and analysis of the data. In Chapter 4, we present the results on K X-ray intensity ratios and vacancy transfer probabilities along with the theoretical, semi-empirical and others experimental values. In Chapter 5, we give the conclusions. -
K shell X-ray Fluorescence Parameters of Platinum and Lead
X-ray fluorescence phenomenon (XRF) has gained importance as a tool the fields of atomic, nuclear and radiation physics, material science, medical physics, and in such diverse fields as industry, agriculture, archaeology, forensic science and so on for elemental analysis. This demands for accurate values of XRF parameters such as shell wise and sub-shell wise x-ray fluorescence yield, fluorescence x-ray production cross-section, Auger transition rate, shell and sub-shell intensity ratios, K to L vacancy transfer probabilities and so on. In addition, measurements of these parameters are useful in obtaining physical parameters such as photoelectric cross-sections, jump ratios and x-ray emission rates. Over the years several researchers have measured these parameters employing variety of methods and detectors (Apaydin and Tira?o?lu 2012; Hopman et al. 2012; Kahoul et al. 2011; Cengiz et al. 2011; Cengiz et al. 2010; M??nesguen and M. -C. L??py 2010; S????t et al. 2009a; S????t et al. 2009b; Reyes-Herrera and Miranda 2008; Ertu?rul et al. 2007; Aylikci et al. 2007; Demir and ?ahin 2007; ?ahin et al. 2005; ??zdemir et al. 2002; ?imsek et al. 2002; Durak et al. 2001; 1998; Allawadhi et al. 1993). However these methods involve complicated single and double reflection geometries armed with sophisticated equipments and strong sources of the order of 109 Bq or more. These experiments involve many corrections such as attenuation of x-rays in the target itself (self attenuation correction), attenuation in the window of the detector (window attenuation correction), solid angle correction, photopeak efficiency and total detection efficiency of the detector, etc. Estimation of intensity of radiations incident on the target is a difficult task in these methods. The incident intensity and the total x-ray fluorescence intensity generated in the target are the quantities, which determine the accuracy of the K x-ray fluorescence parameters. Recently Gudennavar et al. (2003a; 2003b) and Horakeri et al. (2011; 1998; 1997) have developed a simple method to measure K-shell fluorescence yields, production cross section and other parameters by adopting a 2geometrical configuration and employing weak radioactive sources. K x-ray fluorescence parameters are independent of angle of emission because K x-rays are emitted isotropically from the target atom. It was found that the method yields K x-ray fluorescence parameter values as accurate as any standard reflection geometry experiment. The simplicity of method helps one to utilize it to develop student laboratory experiments to train students in x-ray fluorescence field. Since the method requires weak sources, it is of great advantage to student laboratories for they do not need special permission to acquire sources and sources can be handled safely without any personal radiation hazards. However the validity of the target thickness criterion and the method needs to checked with other X-ray detectors such as CdZnTe, HPGe as their construction arrangements are different from NaI(Tl) detectors and for all the elements in the periodic table. In the present study, we have measured the K x-ray fluorescence parameters for the elements platinum and lead using HPGe detector spectrometer and 57Co excitation source. The results are compared with the theoretical, semi-empirical fitted and other experimental values. -
K Shell X-Ray Intensity Ratios and Vacancy Transfer Probabilities of Iron, Silver and Tellurium from Electron Capture Sources
Over the years X-ray fluorescence studies have gained much importance due to the increasing applications in various fields. Today X-ray spectroscopy contributes significantly to the increasing knowledge in different scientific disciplines such as atomic, nuclear and radiation physics, solid-state and semiconductor research, space research, medicine and biomedical research, forensic science, metallurgy, geophysical research and source exploration, industry, archaeology, art, environment analysis and protection, and so on for elemental analysis. X-rays are generated in a wide variety of ways: Proton induced, ion induced, photon induced and X-ray emission following radioactive decay. There are two types of decay processes that result in K shell X-ray emission; electron capture (EC) process and internal conversion (IC) of gamma transitions. It has been reported that the values of K shell X-ray intensity ratios following electron capture (EC) decay are different from the theoretical values as well as those obtained via photon induced excitations. Eventhough several researchers have made attempts to study the K shell intensity ratios by photon excitation methods employing reflection geometries, there are very few reports on the measurements of K shell X-ray intensity ratios of elements following decay processes. In the present investigation, we have determined the K shell X-ray intensity ratios and total vacancy transfer probabilities of iron, silver and tellurium via electron capture decay of Co57, Cd109 and I125 employing 2??-geometrical configuration method. The obtained results are discussed in the light of the effects of electron capture decay on X-ray emission probabilities comparing with theoretical, semi-empirical and experimental results. This dissertation consists of five chapters. Chapter 1 gives a brief introduction to the subject and ends with specifying the relevance of the present investigation. Chapter 2 deals with the theoretical details followed by the literature review and statement of the problem. In the following chapter, we give a brief description on the experimental procedure and data analysis methods. Chapter 4 includes the results and discussions. In the concluding chapter, a summary of the present investigation and the scope for future work are clearly stated. -

Knowledge, preparedness, and resilience related to end of life decision making among family caregivers of ICU patients
End-of-Life decision making is the process that is treating team, patients, and patients??? families go through when considering what treatments will or will not be used to treat a life-threatening illness. In India, End-of-Life Care is a new phenomenon and rarely investigated. The religious and societal attitudes and an absence of education in medical ethics can be seen as reasons for the underdevelopment of End-of-Life Care field. It seems that social workers, particularly who assist patients in Intensive care unit treatment have an important role to play in this regard. Social workers deliver assistance to the critically ill person and their family members as they get admission to the Intensive care unit, enhancing the conversation among treating group, patients and family members. The objective of this study is to assess the knowledge, preparedness and resilience among family caregivers related to End-of-Life decision making. This study utilizes a descriptive research design and purposive sampling method. The study includes 71 first degree relatives of patients who are significantly involved in caring of the patient and related to decision making. All the participants had their family members admitted to the Intensive Care Unit of St. John???s Medical College Hospital, Bengaluru. This study found that there is minimal knowledge among family caregivers and they had no high level of preparedness. There is ethical concern along with finance and they seem to be confused about the decisions taken. Due to lack of awareness among the family caregivers, they surrender the patient to the treating team. Religious conflict is another aspect which is an obstacle to family caregivers for an End-of-Life decision making. The study also found that as the duration of Intensive Care Unit hospitalization increases the resilience among family caregiver???s decreases. It is important that Medical Social workers identify ways to improve End-of-Life care process through interventions. This can be achieved through training in Master of Social Work programs and by educating social workers. The study concludes that there is an immense gap between the family caregivers and the patient with regard to their knowledge on End-of-Life decision making. Hence, this study highlights the importance of Medical Social Worker in Intensive Care Unit to facilitate patient autonomy and the family caregivers??? decisions on the patient.
