    The priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes

    This Thesis was approved for publication on 2021-06-29 at 09:56.Municipal Solid Waste (MSW) management primarily involves recycling, landfilling, and incineration for energy recovery. MSW composition data based on site-specific studies and material flow analysis indicates the presence of plastics in the municipal solid waste stream of U.S. states. Specifically, in an MSW stream solely consisting of paper, food, yard, plastic, metal, and glass material glasses, the plastic fraction ranges between 20 and 25 % in the discarded waste stream of U.S. states. Unfortunately, technological barriers limit the recycling of plastic fractions. In absence of recycling, the non-recyclable plastics and contaminated MSW are landfilled, resulting in environmental emissions. However, given the advancements in air pollution control devices, incineration for energy recovery can be a better alternative to landfilling. Data collected shows that presently incineration capacity of U.S. states is inadequate to process the MSW generated. Further expansion of incineration (waste-to-energy) facilities is unlikely considering the costs associated with the landfilling of incineration residues, i.e., MSWI Ashes. Research investigations had indicated that MSWI ashes can be compositionally comparable to coal fly ash, blast furnace slag, and clay. Thus, the MSWI ashes may find applications as a supplementary cementitious material. Successful utilization of MSWI ashes as supplementary cementitious material can reduce the expenses associated with the landfilling of MSWI ashes and improve the commercial viability of the waste-to-energy (WTE) industry. Despite being compositionally similar to other supplementary cementitious materials, the MSWI ashes are largely unutilized as supplementary cementitious material. This is because the performance of a cementitious system in the presence of MSWI ashes is not well investigated. Thus, in this thesis, the behaviour of cementitious systems containing MSWI ashes was investigated. Specifically, the hydration behaviour of ordinary Portland cement blended with 8 distinct and diverse MSWI ashes was studied. The findings indicate that incorporating these MSWI ashes can either accelerate or retard cement hydration depending upon their composition. Specifically, Cu, Fe, Al, Ti, Si, K, Zn, and Sr from the MSWI ash matrix appear to retard cement hydration, while Pb, Br, S, Ca, and Cl appear to accelerate cement hydration. Based on these results, a performance predicting parameter – Incineration Ash Coefficient (IAC) – was introduced that correlates with the 7-day compressive strength of mortars incorporating MSWI ashes reasonably well (R2=0.79). This new parameter, based on fundamental chemical and physical characteristics of ashes, can aid in the selection and employment of MSWI ashes as supplementary cementitious materials.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-08-01The student, Vikram Kumar, accepted the attached license on 2021-06-25 at 10:27.The student, Vikram Kumar, submitted this Thesis for approval on 2021-06-25 at 11:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #16721 on 2022-01-12 at 13:03:42Made available in DSpace on 2022-01-12T22:51:41Z (GMT).

    【Abstract】 Objective: Fractures of the capitellum and trochlea constitute less than 1% of all elbow fractures and a shear fracture involving the capitellum and extending medially into most of the trochlea is rarely reported. Type IV capitellum fracture is still controversial in regard to its ra-diographic appearance, surgical approach and osteosynthesis. We report 10 cases of type IV capitellum fracture with a view to elucidating its clinical features and treatment outcome. Methods: We treated 10 patients of type IV capitellum fracture with a mean age of 32 years. A uniform surgical approach and postoperative rehabilitation were followed. Results: Nine patients presented to us after a mean of 4 days of injury and one patient was nonunion after 6 months of injury who had been treated conservatively by a bone setter. Double arc sign was absent in 6 cases. Intraopera-tively 6 capitellotrochlear fragments were devoid of soft Chin J Traumatol 2012;15(4):201-205 DOI: 10.3760/cma.j.issn.1008-1275.2012.04.002 Punjab Civil Medical Services-I Mukerian, Punjab, In-dia (Singh AP) Department of Orthopaedics, UCMS & GTB Hospital, Delhi, India (Dhammi IK and Garg V) Swami Premanand Hospital, Mukerian, Punjab, India (Singh AP) *Corresponding author: Tel: 98-72069734, Email: [email protected] C oronal shear fractures of distal end of humeral articular surface involve the capitellum and trochlea. These fractures are difficult to assess accurately on plain radiographs and the limited amount of subchondral bone available for stable internal fixation makes the operative treatment equally difficult. 1 Joint stiffness, instability and osteoarthrosis are complications resulting from treatment failures. 2 The major classification systems are proposed by Bryan and Dubberley et al. 3,4 Type IV fracture is a fracture involving the capitellum and extends to more than lateral half of the trochlea. 1 We report an analysis of ten cases of type IV capi-tissue attachments. By Mayo Elbow Performance Score evaluation, 7 patients got excellent, 2 good and 1 fair results. One patient with associated elbow dislocation developed heterotopic ossification. There was no case of avascular necrosis, osteoarthrosis or fixation failures. Conclusions: Type IV capitellum fractures are rare and belong to complex articular injuries. A good functional out-come can only be achieved with open reduction and stable internal fixation followed by early mobilization. Preopera-tive radiographic assessment and computed tomography help surgeons in choosing the right surgical approach and implants. Good surgical technique and stable internal fixa-tion are the keys to early mobilization and good functional outcome. Key words: Fractures, bone; Elbow joint; Fracture fixation, internal; Bone wire

    A study of the MEDLINE CDROM database, for the period 1969-2000 was undertaken. The purpose was, to identify core areas of research and development, in the field of applications of lasers to humans, along with other bibliometric indicators of research. A total of 34,833 records were retrieved, downloaded and analysed. The results indicate a steady increase in the number of publications every year, from 1970 onwards, with 1997 (2767 articles) and 1998 (2914 articles) being the most productive years. The most prolific contributors were J. Haut, with 95 publications to his credit, followed by M. Landthaler (82), G. Coscas (79), S.G. Bown (73) and P. Bjerring (70). Collaboration among the authors was high, with a maximum of 15 contributors observed in a few articles. The top ranking journal in the field was Ophthalmology, which published 769 articles starting from 1978. USA was way ahead as the country with the highest journal productivity (around 40% of the total number of records), followed by UK and Germany. A total of 103 articles were published from India. English was the preferred language of publication, with 75% of the records being published in English language. In the use of lasers for humans, maximum number of records were found for adult and middle aged populations. Research focussed on the eye and its various diseases. Lasers were found to be used for therapeutic purposes, in surgery and in the diagnosis of diseases. Carbondioxide laser was most frequently used for medical applications. Though there were quite a few references on the adverse effects of lasers, the therapeutic effects far outweighed them
