The study intends to focus on citation, h-index, document type, prolific authors, authorship pattern, degree of collaboration, most preferred journals, publishers, top rated research institutions and research fields under WOS categories

Research Outputs Of The Older Indian Institutes Of Technology (IITs) During Last 50 Years – Analysis With Reference to Web Of Science

The paper attempts to study the publication trend of research articles of the Indian Institutes of Technology – IITs, the elite institutions of India established during 1950-60s (more than 50 years old) and continued to play a leading role in extending quality education and pioneering innovative research in science, engineering and technology almost up to the end of 20th century till new institutions added to this brand. The study intends to measure and analyze the research outputs of the older IITs on the basis of the research articles indexed in Web of Science during last 50 years (1970-2019) with other relevant issues. The result reflects that 5 older IITs together contributed 127481 publications as research output in different types of documents during last 50 years (1970-2019), out of which 116713 were published in the form of articles out of which IIT Kharagpur published maximum number of research articles (IIT Kharagpur published 26688 articles - 22.87%) but while counting the productivity for the blocks of every five years, different IITs achieved highest ranking in different block years. The citation impact, collaboration with national and international institutions, prolific authorship and productive subject areas of research among the institutions found competitive and progressive

Generalized atomic subspaces for operators in Hilbert spaces

summary:We introduce the notion of a $g$-atomic subspace for a bounded linear operator and construct several useful resolutions of the identity operator on a Hilbert space using the theory of $g$-fusion frames. Also, we shall describe the concept of frame operator for a pair of $g$-fusion Bessel sequences and some of their properties

Some properties of controlled K-g-fusion frame have been discussed. Characterizations of controlled K-g-fusion frame are being presented.We also establish a relationship between quotient operator and controlled K-g-fusion frame. Some algebric properties of controlled K-g-fusion frame have been described. Finally, we shall discuss the stability of dual controlled g-fusion frame.Publisher's Versio

Evaluation of minimally invasive plate osteosynthesis of distal femoral fracture by mini-open technique with femoral distractor and traction table: a prospective review of 26 cases

Background: Different methods exist for fracture reduction and submuscular plating in distal femur intra-articular and metaphyseal extra-articular fractures. Apart from knee flexion, femoral distractor and traction table are commonly used for alignment of fractures in minimally invasive techniques.Methods: 26 distal femoral fractures (all closed fractures) were operated (14 cases in traction table, 12 cases in femoral distractor). Partial articular/unicondylar fractures were excluded from our study. Mean patient age was 42 years (range 18 to 60 years). Evaluation was done by knee society score (KSS).Results: Mean time of radiological union was 23.2 weeks (range 20-28 weeks). 23 fractures united uneventfully, one patient had wound infection, and 2 cases had non-union with implant failure. Debridement in infected implant and re-fixation with long plate and bone grafting were done for fracture union in these two cases. According to KSS, excellent outcome were seen in 6 patients, 10 had good, 8 had fair and 2 had poor outcome.Conclusions: Distraction by traction table or femoral distractor helps us to reduce the fracture by overcoming the pull of gastrocnemius in 2 week old fracture correcting hyperextension/recurvatum deformity. This method can be used as viable alternative in minimally invasive plating causing less chance of infection preserving maximal joint movement.

Evaluation of curettage, synthetic bone grafting and fixation with implant in benign osteolytic and cystic lesions of long bones in children and young adults

Background: Curettage is one of the most common treatment options for benign lytic bone tumors and cystic lesions. In children and young adults, the resultant defect is usually filled with synthetic bone graft, which is a natural calcium phosphate hydroxyappatite (HA) in crystalline ceramic form.Methods: Sixteen cases of benign lytic and cystic lesions of bone were managed by simple curettage and grafting using hydroxyappatite blocks. Displaced pathological fractures or impending peritrochanteric fractures were fixed by implant. Commercially available HA was used for this purpose. Mean duration of follow up was 17.5 months (range 12 –30 months). Mean patient age was 11.2 years (range 6–20 years). Radiological staging of graft incorporation was done as per criteria of Irwin et al.Results: Among 16 cases, 2 patients presented with non-ossifying fibroma and 2 patients with simple bone cyst, 12 cases were aneurysmal bone cyst. 5 patients had pathological fracture. Healing of lesion and graft incorporation is seen in all of the cases. At 6 months of follow up 3 cases were in Irwin stage III, 9 cases were in Irwin stage II and 4 cases were in Irwin stage I. At final follow up 10 cases were in Irwin stage III and rest was in Irwin stage II. No recurrence seen till date.Conclusions: We conclude that meticulous curettage and filling of bone cavity by calcium phosphate hydroxyappatite and fixation with implant in displaced pathological fracture or impending fracture is the procedure of choice of management of benign lytic lesions of bone

Free fatty acids regulating action of Capparis decidua fruit on dyslipidemia in rats

Capparis decidua belongs to family Capparidaceae in wastelands of India. The study aim was to determine the role of C. decidua fruits on the free fatty acids (FFA) profile in fat-rich diet (FRD) dyslipidemic rats. The methanolic extract of edible fruit of C. decidua (CD) was given orally to obese dyslipidemic rats at the dose of 125 mg/kg and 250 mg/kg for consecutive 28 days. CD treatment in FRD rats significantly restricts the body weight gains. Blood lipid profile was altered dose dependently and significantly after 4-week treatment with CD to FRD. rats. It significantly (p<0.05) enhanced serum FFA especially, g-linolinate, a-linolinate, arachidonate, ecosapentaenoate, docosapentaenoate and docosahexaenoate. Moreover, w3-PUFA content was also enhanced (50.3% and 78.8%) in the serum of CD treated animals, whereas MUFA was lowered (31.1% and 40%). Therefore, Capparis decidua fruit has a promising role on dyslipidemia and obesity and has the capabilities to regulate beneficial free fatty acids.

Extreme rotational events in a forced-damped nonlinear pendulum

Since Galileo's time, the pendulum has evolved into one of the most exciting physical objects in mathematical modeling due to its vast range of applications for studying various oscillatory dynamics, including bifurcations and chaos, under various interests. This well-deserved focus aids in comprehending various oscillatory physical phenomena that can be reduced to the equations of the pendulum. The present article focuses on the rotational dynamics of the two-dimensional forced damped pendulum under the influence of the ac and dc torque. Interestingly, we are able to detect a range of the pendulum's length for which the angular velocity exhibits a few intermittent extreme rotational events that deviate significantly from a certain well-defined threshold. The statistics of the return intervals between these extreme rotational events are supported by our data to be spread exponentially. The numerical results show a sudden increase in the size of the chaotic attractor due to interior crisis which is the source of instability that is responsible for triggering large amplitude events in our system. We also notice the occurrence of phase slips with the appearance of extreme rotational events when phase difference between the instantaneous phase of the system and the externally applied ac torque is observed.Comment: 10 pages, 7 figures, Comments are welcom
