Elbow Arthroscopy

Introduction: Elbow joint is a complex articulation of three bones. It is a hinge joint with three types of motions; flexion-extension, varus-valgus and rotations. With advancement of instrumentations, our knowledge about surgical anatomy and surgical skills, elbow arthroscopy has become an excellent tool to treat a wide range of disorders with minimum risk and complications

Investigation of synthetic methods for preparation of 2\u3csup\u3eo\u3c/sup\u3e-amino derivatives of 5-amino- 1, 10-phenanthroline: Applications to Cu\u3csup\u3e+2\u3c/sup\u3e based impedance sensors

The main purpose of this project is to synthesize 2o - derivatives of 5-amino-1, 10- phenanthroline (5-aphen) for application as self-assembled monolayers on gold interdigitated electrode array chips in standard impedance and impedance resonance-based Cu2+ sensors. Potential applications include monitoring Cu2+ leaching from anti-fouling coatings on ship hulls. The importance of the planned secondary alkyl amino derivatives will be to test their binding properties to the gold surface through dithiocarbamate linkages by monitoring the IDE impedance signal. Practical sensor development requires good impedance response, maximum binding to the gold IDE chip, and maximum long term stability of the SAM, which provides the transducer element with sensitivity, selectivity, and reproducibility. In research work, three different synthetic routes were investigated for preparation of secondary N-alkyl 5-aphen derivatives. KI- catalyzed mono alkylation of 5-aphen with alkyl halides gave significantly better results than Pd/C catalyzed mono N-alkylation with aldehydes and alkylation of 5-aphen with the PPh3/DDQ system

Tension fatigue of glass/epoxy and graphite/epoxy tapered laminates

Symmetric tapered laminates with internally dropped plies were tested with two different layups and two materials, S2/SP250 glass/epoxy and IM6/1827I graphite/epoxy. The specimens were loaded in cyclic tension until they delaminated unstably. Each combination of material and layup had a unique failure mode. Calculated values of strain energy release rate, G, from a finite element analysis model of delamination along the taper, and for delamination from a matrix ply crack, were used with mode I fatigue characterization data from tests of the tested materials to calculate expected delamination onset loads. Calculated values were compared to the experimental results. The comparison showed that when the calculated G was chosen according to the observed delamination failures, the agreement between the calculated and measured delamination onset loads was reasonable for each combination of layup and material

Impact of Information Technology Innovations on Resources and Services of Management Institute Libraries in Mumbai: A Librarians’ Approach

Abstract Management libraries are facing a piquant situation and unforeseen challenges in this age of information technology. They are reeling under pressure to fulfill their obligation of meeting the diverse information needs of clientele. IT has brought in sweeping changes in the traditional way libraries are functioning. Libraries need to evaluate, measure the impact of information technology on them. This will equip them with the knowledge of turning this information Technology into a boon for improving their services. This paper is one such attempt with reference to management libraries affiliated to University of Mumbai, Mumbai City, India

Treatability and Flow Path Studies in Bamboo Part I. Dendrocalamus Strictus Nees.

Bamboo is one of the strongest structural materials used in rural areas of developing countries. Because of its low durability, it often fails prematurely due to fungal, borer, and termite attack. Because of anatomical differences from both hardwoods and softwoods, difficulties in treatment have been encounterd and early failures in preservative treated bamboo often observed. The most important structures for flow of fluids are the vascular bundles. The vascular bundles occurring in the inner zone of the bamboo culm treat better than the vascular bundles at the periphery.Microscopic studies on the distribution of chemicals in Dendrocalamus strictus Nees. indicated that creosote: fuel oil penetrated more uniformly than water-soluble or organic solvent stains. The degree of penetration decreased with the increasing distance of other cells such as fibers and parenchyma tissues from the conducting vessels. At the microscopic level, treatability behavior improved from outer to inner zones along the wall thickness as well as from basal internodes to top internodes

Penetration Indices of Hardwoods: A Quantitative Approach to Define Treatability

Fluid accessibility of various structural components of 15 hardwoods belonging to different treatability classes was studied by using water-soluble and organic solvent stains. Penetration was found to vary even among the species categorized under the same treatability class indicating large-scale variation within the existing treatability classes. A quantitative estimation of this behavior was obtained in the form of a penetration index. This approach indicates that treatability class needs a change for 5 of the 15 species studied

An Empirical Study on the Impact of HRD Practices on NPOs in Utilizing Foreign Contributions Received

Nonprofit organizations in India represent a significant portion and they make a strong contribution to the economic wellbeing of our country. The human resources are vital for achieving the sustainable growth and development of organization. Firstly, objective is to analyze the workforce perception of NPOs towards the HRD practices of NPO. Secondly, the amount of FCR and FCU by NPOs are analyzed and compared. Thirdly, the efficiency of NPOs is measured based on their HRD practices. Lastly the impact of HRD practices on the efficiency of NPOs are measured. Based on the objective’s hypothesis were formulated and tested. The study found that the NPO’s workforce has positively perceived HRD practices followed in their organization. The respondents have agreed and given a positive opinion towards the HRD practices viz., appraisal system, Training and development, career development and recognition, and organizational environment followed in their organizations. The study found that HRD practices have a significant positive impact on the development of NPOs in Karnataka.  Large-sized NPOs are generating larger amount, whereas small-sized NPOs are acquiring lesser number of foreign contributions. NPOs with better HRD practices are efficient in utilizing the foreign contributions received by them. The efficiency of the NPOs increases as they adapt better HRD practices, and the efficiency of NPOs decrease as they ignore HRD practices
