The target of the National Solar Mission is to build up India as a worldwide pioneer in solar energy generation. Solar power can be transmitted through grid either from solar photovoltaic or solar thermal technology. As compared to solar photovoltaic, solar thermal installations are less studied, especially regarding energy estimation and performance analysis. For estimating the potential of CSP plants, it is planned to simulate a power plant. We have marginally modified the design of 1 MW operational power plant installed at Gurgaon using Parabolic Trough Collector (PTC) technology. The results are compared with the expected output of Gurgaon power plant and also 50 MW power plant at Rajasthan. Our results have closely matched with a small deviation of 3.1% and 3.6% for Gurgaon and Rajasthan plants, respectively. Our developed model is also validated with 18 different solar power plants in different parts of the world by slightly modifying the parameters according to the plant capacity without changing major changes to the plant design. Difference between our results and the expected energy generation varied from 0.4% to 13.7% with an average deviation of 6.8%. As our results show less than 10% deviation as compared to the actual generation, an attempt has been made here to estimate the potential for the entire nation. For this modelling has been carried out for every grid station of 0.25° × 0.25° interval in India. Our results show that annual solar thermal power plant of 1 MWe capacity potential varies from 900 to 2700 MWh. We have also compared our results with previous studies and discussed.

A massive plan has been drawn by the Karnataka state of India to initiate several solar power plants at different locations. In view of this, it is of great help to have reliable estimation on solar PV energy generation. Four solar PV power plants in Karnataka state are fully operational installed by Karnataka Power Corporation Limited (KPCL). They are located at Kolar, Belgaum and Raichur with 3 MW capacity each and at Mandya with 5 MW capacity. In the present study, using ground mounted weather station data solar power generation has been estimated and compared with actual generation for two consecutive years of 2012 and 2013 for one location initially, namely 3 MW Kolar Solar PV Plant. The procedure is repeated for rest of the plants. The simulated results have been corrected with ground mounted weather data. After such corrections, the simulated results have been compared with the actual energy generation of the four plants. Results showed a close match with a small deviation of about 5%. The model then applied throughout the state for every 0.25 degree station intervals in a grid manner. The annual energy generation obtained for the state varies from 1.53 to 1.73 MUs/MW. Central and south eastern part of the state are found to yield significantly higher solar power generation as compared to the northern part and south western part of Karnataka. Interestingly, north western part of Kodagu district has shown the least potential of 1.53 MUs/MW as compared to other parts. This can be attributed mainly due to low irradiation and high temperature condition at this location. The energy generated map from our study will be useful and helpful for both solar developers and decision makers of Karnataka state.

Purpose:Anterior cruciate ligament (ACL) repair was first described in the mid 1900's. However, due to poorly selected patients led to unsatisfactory early results. We aim to study the outcome of ACL repair in a carefully selected ***:Thirteen consecutive patients of acute Type 1 (proximal ACL avulsion) were treated with arthroscopic ACL repair using a suture pull out technique. At the latest follow-up the patients were evaluated for Lysholm score, KT-1000 measurement and clinical assessment for any ***:At a mean follow-up of 31.3 months, none of the patients had any subjective laxity. The mean Lysholm score was 95 and instrumented laxity measurement did not reveal any significant laxity compared to the opposite ***:The proximal ACL avulsion has healing potential similar to proximal MCL injuries. Performing microfracture of the lateral wall of the notch optimizes the healing environment by negating the effects of the synovial fluid. Performing ACL repair in a carefully selected patient leads to good short term results and saves the patient of a reconstruction procedure, at least in the immediate future.

Flexible bronchoscopy is a common procedure. Training in bronchoscopy is a complex process involving learning technical skills, understanding indications and contraindications, risks and benefits of the procedure, working within the team and communicating with patients. It is expected that a competent bronchoscopist is able to maneuver the scope through the anatomically complex bronchial tree, take samples, manage the sedated patient and communicate with nursing staff. Learning the complex procedural skills in the clinical setting can be stressful, therefore current bronchoscopic training methodology should blend a number of learning methods including didactic lectures, web-based material, high and low fidelity simulators as well as supervised apprenticeship training. Simulation-based bronchoscopy training therefore has been explored as a mode of training bronchoscopy skills. In this article, the role of simulation-based bronchoscopy training is reviewed. The low fidelity and high fidelity virtual reality bronchoscopy models are described together with the evidence available to support the use of simulation for bronchoscopy training.
