Content Analysis of Journal Literature published from UK and USA

This paper aims to identify the types of research papers/articles, current trends in the choice of subjects, being included in the Library and information science (LIS) journal literature published from UK and USA. The study also aims to find out the impact of information and communication technology (ICT) on LIS subject fields. A content analysis of 165 research papers and journals articles published in the year 2008 in six LIS journals was conducted. Findings indicate that 93 (56.36%) of the articles out of the total 165 were research based. The variation is found with regard to coverage of core subject areas published from UK and USA. This study will try to fill gaps in library and information science research as it can helps in identifying the fields on which major work has been done as well as the subjects which are not worked upon. Project of this type, done for different years, would provide valuable information concerning the nature of research in librarianship and its development

Evaluation of Library Websites of Colleges Affiliated to University of Delhi: A Content Analysis Study

Abstract Purpose- This paper aims to analyse the content of libraries’ websites of colleges affiliated to University of Delhi in India. Design/methodology/approach-In the present study, observation method was used to analyse the content which was uploaded on the websites of selected ten colleges of University of Delhi. The data and content uploaded on the websites was collected and analysed with the help of checklist specifically designed for this purpose. Findings- Most of the college libraries uploaded information about its collection on the website. It was found that few college libraries have been using web 2.0 tools. It has been noticed that these tools have not been used extensively for promoting the use of library collection and services. Majority of the college libraries provided few useful links on its’ websites. For the optimum use of library resources and services the libraries need to be more informative, well-structured attractive and user friendly. Practical Implication- College library website is very useful for all types of users especially for differently abled belonging to economically weaker section. It is also important that their libraries should upload information about special collections such as book bank material, braille materials, reference resources, CD/DVDs, maps, charts etc. on its\u27 website. Originality/value –World Wide Web has been changing the mode of information dissemination in college libraries. It is also important that their libraries play an important role to develop the knowledge and personality of academic community

Analysing Information Seeking Behavior of College Students in Changing Environment

This research paper investigated the information seeking behavior of college students surveying twelve colleges affiliated to the University of Delhi. Different variable sets were used to analyse the undergraduates’ reading habits, information needs, information search and information use behavior. Total 506 undergraduate students of different disciplines such as sciences, social sciences and humanities were selected as a sample applying multistage and stratified sampling techniques. The study applied SPSS, Version-25 for analysing the various aspects of the study. Results revealed that books were the most preferred source of information among 84.2 percent of the undergraduate students followed by newspapers (64.9 percent) and magazines (43.7 percent) in all the three disciplines. In addition, 34.3 percent undergraduate students were inclined for reading books in more often printed less often electronic format, newspapers (37.3 percent) respondents in both printed and electronic in equal proportion and magazine (52.4 percent) in more often electronic and less often printed format. On the basis of weighted mean, keyword search (206.3 WM) followed by phrase search (159.1 WM) were always used by the students for information search and retrieval. The maximum number of 24.7 percent respondents in humanities, sciences (23.5 percent) and social sciences (23.3 percent) found print resources more reliable than electronic resources

Semi-Implicit finite-difference methods to study the spin-orbit and coherently coupled spinor Bose-Einstein condensates

We develop time-splitting finite difference methods, using implicit Backward-Euler and semi-implicit Crank-Nicolson discretization schemes, to study the spin-orbit coupled spinor Bose Einstein condensates with coherent coupling in quasi-one and quasi-two-dimensional traps. The split equations involving kinetic energy and spin-orbit coupling operators are solved using either time-implicit Backward-Euler or semi-implicit Crank-Nicolson methods. We explicitly develop the method for pseudospin-1/2, spin-1, and spin-2 condensates. The results for ground states obtained with time-splitting Backward-Euler and Crank-Nicolson methods are in excellent agreement with time-splitting Fourier spectral method which is one of the popular methods to solve the mean-field models for spin-orbit coupled spinor condensates. We confirm the emergence of different phases in spin-orbit coupled pseudospin-1/2, spin-1, and spin-2 condensates with coherent coupling

The Ras activator RasGRP3 mediates diabetes-induced embryopathy and ET1-induced vessel morphogenesis

Blood vessel formation is critical throughout the life of vertebrate organisms, and vessel dysfunction jeopardizes both fetal development and adult survival. Diseases such as diabetes disrupt vessel regulation and contribute to numerous vascular pathologies. Therefore, understanding blood vessel regulation in pathological conditions is essential to devising preventative treatments. The work presented in this dissertation aims to understand how perturbations in the Ras activator, Ras guanyl-releasing protein 3 (RasGRP3), mediate aberrant vessel morphogenesis. We have identified RasGRP3 as a downstream component in an endothelin-1 (ET1) signaling pathway. ET1 signaling is a primary mediator of vascular pathology in diabetes. I hypothesized that RasGRP3 mediates diabetes-induced embryopathy and changes in endothelial cell behavior and vessel morphology. Work by Joanna Fried and Jessica Heinz demonstrated that RasGRP3 is required for embryogenesis in diabetic conditions. In collaboration with Dr. Svetlana Rylova, I determined that activated RasGRP3 promotes Ras-ERK signaling, which can be induced by phorbol ester or endothelin-1 (ET1). Dr. Rylova demonstrated that overexpression of activated RasGRP3 is sufficient to induce Ras-ERK activation and perturb directional migration. In collaboration with Stephanie Kiser, I showed that RasGRP3 is required for ET1-induced Ras activation, proliferation and migration in endothelial cells. Using an embryonic stem cell model to simulate pathological angiogenesis, we also identified a role for RasGRP3 in ET1-induced vessel dysmorphogenesis. By identifying the molecular requirements that mediate RasGRP3-dependent effects, we can understand how changes in cellular or morphological processes induce vascular pathology. The data herein advance our understanding of RasGRP3-vessel pathology as they may pertain to diabetic conditions

FORTRESS II: FORTRAN programs for solving coupled Gross-Pitaevskii equations for spin-orbit coupled spin-2 Bose-Einstein condensate

We provide here a set of three OpenMP parallelized FORTRAN 90/95 programs to compute the ground states and the dynamics of trapped spin-2 Bose-Einstein condensates (BECs) with anisotropic spin-orbit (SO) coupling by solving a set of five coupled Gross-Pitaevskii equations using a time-splitting Fourier spectral method. Depending on the nature of the problem, without any loss of generality, we have employed the Cartesian grid spanning either three-, two-, or one-dimensional space for numerical discretization. To illustrate the veracity of the package, wherever feasible, we have compared the numerical ground state solutions of the full mean-field model with those from the simplified scalar models. The two set of results show excellent agreement, in particular, through the equilibrium density profiles, energies and chemical potentials of the ground-states. We have also presented test results for OpenMP performance parameters like speedup and the efficiency of the three codes

To Study The Efficacy Of Reciprocating Single File System And Multifile Rotary Systems In Elimination Of Root Canal Bacteria And Endotoxins

AIM: To study the efficacy of reciprocating single file system and multifile rotary systems in elimination of root canal bacteria and endotoxins. MATERIAL AND METHOD: Forty permanent single rooted mandibular premolars with straight canals inoculated with Escherichia Coli suspension for 21 days were selected for the study. Teeth were randomly divided into four groups (n=10) according to instrumentation system: Grp. A–Reciproc (VDW); Grp. B–WaveOne (Dentsply Maillefer); Grp. C–MTwo (VDW); and Grp. D–K3( Sybron Endo); Bacterial and endotoxin samples were collected with a sterile paper point before instrumentation  and after instrumentation. Culture methods estimated the colony-forming units (CFU) and the Limulus Amebocyte Lysate test was used for quantification of endotoxins. Results so obtained were calculated and statistically analysed.  RESULT: Results at S1 concluded that bacteria and endotoxins were found in all of the investigated root canals. After instrumentation all systems were associated with the significant reduction of the bacterial load and endotoxins respectively: Grp. A– Reciproc (88.25% and 89.10%); Grp. B– WaveOne (83.53% and 80.59%); Grp. C– MTwo(79.41% and 75.84%) and Grp. D– K3 (67% and 74.4%). Statistically no difference was found amongst the instrumentation systems regarding bacteria and endotoxin elimination (P <0.05).  CONCLUSION: The reciprocating single file, Reciproc and WaveOne were as effective as the multifile rotary systems for the eradication of bacteria and endotoxins from root canals

Male breast cancer: a budding and unaddressed issue

Incidence of male breast carcinoma (MBC), although rare, recently has an increasing trend. The increase in incidence is associated with increasing age, and poor clinical outcome seen with MBC is mostly because of illiteracy and lack of health education and shyness in reporting to the clinical physician. In this context, a comprehensive review regarding this forth bursting clinical scenario is important. The present article focus on that aspect encompassing but not limited to different clinical studies. The randomized trials on MBC are sparse and most of the studies are retrospective in nature due to rarity of cases. MBC treatment line is derived from female breast cancer guidelines. MBC has a poorer prognosis than female breast cancer. MBC patients in India present in advanced stage and surgery remains challenging due to paucity of breast tissue. Post mastectomy radiation is indicated on the same lines as of female breast cancer and it decreases locoregional recurrence. Adjuvant hormonal therapy decreases recurrence and improves survival. Further clinical trials are required including large number of patients to study different parameters in respect of prognosis and survival
