This study aims to explore various skills of library professionals working in management institutions of Kerala State, India.

A survey method was used by distributing online questionnaire as a data collection tool. The questionnaires were distributed to the library professionals working in management institutions in Kerala State, India.

The study’s results revealed that the library professionals were competent with managerial, communication and interpersonal skills. Conversely, they were lacking skills in statements such as institutional repository, web 2.0 and social networks. Their familiarity level with reference management tools, research and academic ethics, electronic publishing and management of open-access resources, were also not satisfactory. They need knowledge of other ICT skills such as designing and maintaining in-house databases, video conferencing tools, advanced troubleshooting creating and managing metadata, handling RFID technology and knowledge in solving issues while organizing webinars. Based on the findings, the study has suggested some recommendations which will enable the government/institutions to take appropriate measures to improve their skills.

This study will enable the policymakers to identify in which area the library professionals are weak and develop a strategy and framework for increasing the level of their skills.

This study provides the views of the library professionals working in management institutions in India and warrants the library professionals to enhance their skills, especially on research ethics and publications and ICT skills.

This study aims to determine the level of knowledge in searching, evaluating, information management competency and to find differences among research scholars’ in terms of their information literacy (IL) competency with regards to gender and academic designation.

A survey method was conducted to collect the data from the research scholars’ pursuing their doctoral degrees in Manonmaniam Sundaranar University, Tamil Nadu, India.

The results of this study revealed that the majority have used simple search and were not using the Online Public Access Catalogue. They were not able to assess the information retrieved and the assistance from the library staff to locate the resources was found to be minimal. This study also highlighted some of the problems faced by the research scholars and provided some suggestions based on the findings. This study highlights the need to adopt a new IL framework and conduct user literacy training programmes for effective use of the resources.

This study also has practical implications in terms of assessing the IL competency among the research scholars and significant variations which identified through demographics and assessment of IL competency will enable policymakers to develop a framework for brand new literacy instructions. The results may help to frame long-term strategies to motivate and train the research scholars in the effective use of technologies for improving their academic performance.

This study used a questionnaire as tool to collect the data. The outcome of the results will help the librarians and authorities to discuss research scholars’ IL competency and take appropriate decisions to improve their IL skills.

This paper aims to focus on the information literacy skills and how the resources are being used by medical students of Mahatma Gandhi Medical College and Research Institute (MGMCRI), Pondicherry, India. The main aim is to determine the medical students use, purpose, search strategies and sources through which aware and literacy skills acquired. Further, this paper aims to bring out the problems faced.

A survey method was conducted through a structured questionnaire distributed among 120 medical students from first year to fourth year. Stratified random sampling was used for selection of students.

Findings of the study revealed that medical students largely used medical databases such as Bentham Sciences, ProQuest, PubMed and MedlinePlus. Further, the paper reveals that majority used health information for updating their knowledge and to acquire general information. The students’ information literacy level found minimal, which may be the reason majority of the students found difficulty in locating the desired materials followed by irrelevant information, inadequate e-resources and lack of awareness reported some extent.

The recommendations made based on the study are expected to be beneficial to the authorities and library administration of the surveyed institution to take appropriate measures for effective utilization of resources.

The purpose of this study is to report the results of a survey conducted at Bharathidasan and Alagappa Universities to determine the research scholars' awareness, use of Open Access (OA) resources, reasons for using, impact of OA on the research scholars' research, satisfaction and problems faced.

In this study, a self-assessed questionnaire was developed to collect data from the research scholars pursuing their research degrees from Bharathidasan and Alagappa Universities of Tamil Nadu, India. A total of 400 research scholars from various disciplines responded were used for analysis.

The results indicated that the majority of research scholars aware of few OA resources to a large extent and afraid to redistribute the sources as they fear of copyright issues. Easy to use, more informative and global research at one place were the major reasons for accessing the resources. The research scholars were aware of OA features and OA's impact such as freedom to use, modify, resources available with source code, reliability, self-archiving, quick publishing, more citations etc. Delay in downloading and lack of computer terminals to access the resources were the major issues faced by the research scholars. On the whole, the researchers are considering OA model as an alternative to business model and expect the university librarians to promote and enhance the accessibility of OA resources.

The outcomes of the results will enable the librarians and authorities in universities to formulate appropriate decisions to remove the issues faced by the research scholars and develop a framework for new literacy instructions.

The study undertaken is new to the Indian continent and the Tami Nadu state in particular. The findings of the study will be useful to improve the awareness level and use of OA resources effectively.

In comparison to a nozzle with a larger/finite separation distance (Thanigaiarasu et al., 2019), a thin-lip nozzle (Srinivasarao et al., 2017) minimizes drag. Coaxial nozzles with thin lips are an appropriate tool for studying high subsonic jets because it does not create a dominant re-circulation zone. This study aims to analyze the characteristic of separation distances, between primary and secondary nozzles, within the range of 0.7–3.2 mm which can be considered a thin lip.

A separation distance of 0.7  (Papamoschou, 2004), 1.7  and 2.65 mm (Lovaraju and Rathakrishnan, 2011) is considered for the present study. The main nozzle exit Mach number is maintained at a subsonic condition of Mach 0.6, and the co-flowing nozzle exit Mach number is varied from 0% (secondary jet stopped/single jet) to 100% (Mach 0.6) in steps of 20% with respect to the main nozzle exit Mach number. A comparison was made between these velocity ratios for all three lip thicknesses in the present study. Design mesh and analysis were done by using Gambit 2.6.4 and Fluent 6.12. Velocity contours and turbulence contours were studied for qualitative analysis.

When lip thickness increases from 0.7 to 2.65 mm, the potential core length (PCL) of the primary jet decreases marginally. Additionally, the PCL of the primary jet elongates significantly as the velocity ratio increases. The primary shear layer is dominant at 20% co-flow (20 PCF), less dominant at 60% co-flow (60 PCF) and almost disappeared at 100% co-flow (100 PCF). Concurrently, the secondary shear layer almost disappeared in 20 PCF, dominant in 60 PCF and more dominant in 100 PCF. Different zones such as initial merging, intermediate and fully merged zones are quantitatively and qualitatively analyzed.

Co-flow nozzle is used in turbofan engine exhaust. The scaled-down model of a turbofan engine has been analyzed. Core length is directly proportional to the jet noise. The PCL signifies the jet noise reduction in a high-speed jet. For a low-velocity ratio, the potential core is reduced and hence can reduce the jet noise. At the same time, as the velocity ratio increases, the mass flow rate of the coaxial increases. The increase in the mass flow increases the thrust of the engine. The aircraft engine designer should analyze the requirement of the aircraft and choose the optimal velocity ratio coaxial nozzle for the engine exhaust (Papamoschou, 2004).

There have been many research studies carried out previously at various lip thickness such as 0.4  (Georgiadis, 2003), 0.7  (Papamoschou, 2004), 1.5  (Srinivasarao et al., 2014a), 1.7  (Sharma et al., 2008), 2  (Naren, Thanigaiarasu and Rathakrishnan, 2016), 2.65  (Lovaraju and Rathakrishnan, 2011), 3  (Inturiet al., 2022) and 3.2 mm (Perumal et al., 2020). However, there is no proper study to vary the lip thickness in this range from 0.7 to 3.2 mm to understand the flow behavior of a co-flowing jet.

The effect of increasing lip thickness (LT) and Mach number on subsonic co-flowing Jet (CFJ) decay at subsonic and correctly expanded sonic Mach numbers has been analysed experimentally and numerically in this study. This study aims to a critical LT below which mixing enhances and above which mixing inhibits.

LT is the distance, separating the primary nozzle and the secondary duct, present in the co-flowing nozzle. The CFJ with LT ranging from 2 mm to 150 mm at jet exit Mach numbers of 0.6, 0.8 and 1.0 were studied in detail. The CFJ with 2 mm LT is used for comparison. Centreline total pressure decay, centreline static pressure decay and near field flow behaviour were analysed.

The result shows that the mixing enhances until a critical limit and a further increase in the LT does not show any variation in the jet mixing. Beyond this critical limit, the secondary jet has a detrimental effect on the primary jet, which deteriorates the process of mixing. The CFJ within the critical limit experiences a significantly higher mixing. The effect of the increase in the Mach number has marginal variation in the total pressure and significant variation in static pressure along the jet axis.

In this study, the velocity ratio (VR) is maintained constant and the bypass ratio (BR) was varied from low value to very high values for subsonic and correctly expanded sonic. Presently, commercial aircraft engine operates under these Mach numbers and low to ultra-high BR. Hence, the present study becomes essential.

This is the first effort to find the critical value of LT for a constant VR for a Mach number range of 0.6 to 1.0, compressible CFJ. The CFJs with constant VR of unity and varying LT, in these Mach number range, have not been studied in the past.

The research investigated relations between factors used to evaluate the quality of buyer-supplier relationships (BSRs): perceived performance of the supplier, satisfaction with supplier, and trust in the supplier; and to develop an instrument to evaluate BSRs (a BSRs evaluation scale).

We applied the psychometric testing of the BSRs measurement using exploratory factor analysis and confirmatory factor analysis. We applied structural equation modeling (SEM) to understand the interrelations of factors underlying BSRs.

The BSRs evaluation scale consists of three factors: perceived performance of the supplier, satisfaction with the supplier, and trust in the supplier. The results provide empirical evidence of the validity, reliability, and generalizability of the presented measurement.

The study developed a novel measurement instrument that integrates BSRs’ multidimensional constructs. It explains and confirms the significant roles of satisfaction with the supplier, trust in the supplier, and perceived performance of the supplier in shaping the BSRs’ quality. Furthermore, we provide evidence that in BSRs goodwill- and competence-based trust integrate into a single factor.

The purpose of this paper is to identify key social medial channels which pharmaceutical firms need to consider when desiring to understand consumer behavior, build, maintain and proactively manage relationships. Also, it proposes the application of analytic hierarchy process (AHP) sensitivity analysis algorithm to test the stability or robustness of the priority ranking. Specifically, this paper leverages performance sensitivity analysis to evaluate how small changes (perturbation) in the major objectives of the pharmaceutical relationship marketing (PRM) tactics within the social media environment will influence the ranking of the alternative course of actions.

This paper used AHP-based questionnaire survey to evaluate the relative importance of factors accounting for PRM and the impact of social media channels. The major objectives and the alternative strategies used were from literature reviewed. Interviews with senior managers were insightful and helpful in the wording, content and format of the questionnaire.

Customer engagement is the most important PRM tactic, followed by communication and trust. The performance sensitivity analysis carried out on the PRM tactics showed that the ranking associated with social media channel options remained robust or insensitive to small perturbations.

The data procured for this paper were based on one focal pharmaceutical firm. Convincing the same to grant an interview and late responding to the questionnaire was a great challenge.

Social media impact on pharmaceutical marketing relationship is important for pharmaceutical marketers. PRM bodes well with the social media environment. Pharmaceutical industry can build and maintain relationships with consumers through social media. Firms that leverage social media to enhance their PRM tactics will be viewed favorably in terms of trust, transparency, openness and honesty. The results provide pharmaceutical marketing managers with insightful and valuable information with respect to the role or social media impact on the PRM. The AHP model, objectives and their relative importance provide valuable information for managers on how to monitor the values that matters to customers the most.

This paper is one of the very few on the PRM and perhaps the first that examines social impact leveraging the AHP model. In addition, this paper contributes to the relationship marketing literature by leveraging a multi-criteria decision-making algorithm to prioritize the most important factors accounting for the PRM strategies.

Detecting cancer from the computed tomography (CT)images of lung nodules is very challenging for radiologists. Early detection of cancer helps to provide better treatment in advance and to enhance the recovery rate. Although a lot of research is being carried out to process clinical images, it still requires improvement to attain high reliability and accuracy. The main purpose of this paper is to achieve high accuracy in detecting and classifying the lung cancer and assisting the radiologists to detect cancer by using CT images. The CT images are collected from health-care centres and remote places through Internet of Things (IoT)-enabled platform and the image processing is carried out in the cloud servers.

IoT-based lung cancer detection is proposed to access the lung CT images from any remote place and to provide high accuracy in image processing. Here, the exact separation of lung nodule is performed by Otsu thresholding segmentation with the help of optimal characteristics and cuckoo search algorithm. The important features of the lung nodules are extracted by local binary pattern. From the extracted features, support vector machine (SVM) classifier is trained to recognize whether the lung nodule is malicious or non-malicious.

The proposed framework achieves 99.59% in accuracy, 99.31% in sensitivity and 71% in peak signal to noise ratio. The outcomes show that the proposed method has achieved high accuracy than other conventional methods in early detection of lung cancer.

The proposed algorithm is implemented and tested by using more than 500 images which are collected from public and private databases. The proposed research framework can be used to implement contextual diagnostic analysis.

The cancer nodules in CT images are precisely segmented by integrating the algorithms of cuckoo search and Otsu thresholding in order to classify malicious and non-malicious nodules.
