Arthroscopic decompression and debridement for the treatment of anterior cruciate ligament ganglion cyst in a 45-year-old female

Anterior cruciate ligament (ACL) cysts are infrequently encountered in clinical practice, with limited reported cases. These cysts usually present with chronic knee pain and clinical examination is usually unremarkable except for knee tenderness. Due to the lack of characteristic symptoms and deficiency of precise clinical techniques to diagnose the condition, timely diagnosis requires a high index of suspicion, supported by magnetic resonance imaging (MRI). Hence management of ACL ganglion cysts poses unique challenges for healthcare providers. We present a case study of a 45-year-old female with an ACL ganglion cyst successfully treated with arthroscopic decompression and debridement. This article outlines the clinical presentation, diagnostic workup, surgical intervention, and post-operative outcomes of this case, providing insights into the effective management of this uncommon condition. Furthermore, we provide a comprehensive review of the existing literature on ACL ganglion cyst, emphasizing findings and treatment outcomes reported in previous studies. This case underscores the importance of considering ACL cysts in the differential diagnosis of knee pain and discomfort. Early identification and appropriate management, such as arthroscopic cyst excision, can lead to favorable outcomes and complete recovery

Development of a metalised carbon fiber reinforced plastic (CFRP) antenna reflector for satellite communication

The Antenna reflectors made of Carbon Fibre Reinforced Plastics (CFRP) are used in spacecrafts for Satellite Communication in C, S and Ku bands. For futuristic Satellite Communication applications in x2018;Kax2019; band, there is a need of improving the reflectivity for Radio Frequency (RF) signals by metallising the surface of CFRP reflectors. The space qualified CFRP reflectors have been developed by ISRO for various GEOSAT projects but the process for developing a space qualified reflector having a metallized surface has not been established in the country. Recently, efforts in this hither to fore unexplored domain have been made jointly by Space Application Center, Ahemadabad and National Aerospace lab, Bangalore to develop reflectors with metallized surface

Investigation of Intra/ply Shear Behavior of Out-of-Autoclave Carbon/Epoxy Prepreg

The forming of a composite part without defects has been a challenging issue till date due to the complexity of the process. Lack of knowledge on the in- plane shear behavior of the composite during forming has always served as the prime reason for the defects. Still, a sound knowledge of diverse phenomena which make these flaws such as wrinkling, would help to optimize the performance. In addition, the possibility to form a composite part from out-of-autoclave prepreg without any defect would further enhance the process due to the cost reduction caused by eliminating the autoclave. The work presented herein aims to investigate the intra-ply shear behavior of out- of- autoclave carbon epoxy thermoset prepreg and its effect on wrinkling using the picture frame and bias extension tests. Tests will be performed at varying temperatures and displacement rates in order to determine their contribution on deformability of the fabric. Digital image correlation was applied onto the set-up to take sequential images at various stages of deformation and capture the onset of wrinkling. Microstructural analysis was performed in order to observe the change in tow geometry throughout the shear deformation. In addition, the uni-directional and woven prepreg (8- harness and 5- harness) were compared to the scale of their deformability to determine the material which favors the forming the most. Finally, based on the response of the operating temperature (resin viscosity), displacement rate and layer counts (layer interactions) on the onset of wrinkling, an optimization method was generated using the Taguchi and Analysis of Variance technique to determine the parameter which influences, wrinkling the most

METHOD OF IMPROVING ACCURACY FOR OBJECT DETECTION IN AN ANNOTATION SYSTEM

A method for improving accuracy of object detection or recognition in an annotation system while minimizing human effort is disclosed. This system runs an already trained detector on unannotated data for detecting objects from data such as image or video. Decisions are availed from human annotation only as the detected object is correct or incorrect. Images confirmed as not containing the object are then fed as ‘negative’ data. Images confirmed as containing the object can be further annotated for the exact bounding box, and then fed as ‘positive’ data to the machine learning algorithm. The process of presenting data to the algorithm can be iterated until the detector accuracy saturates. The advantages of using the method include improved object detection accuracy with minimal human effort

Phenotypic detection of Metallo Beta Lactamase Producing Pseudomonas aeruginosa among Clinical Isolates from the intensive care unit of a tertiary care centre

Background: Pseudomonas aeruginosa is an opportunistic pathogenic bacterium responsible for both, acute and chronic infection, causing serious infections in patients who are mechanically ventilated individuals, who are immunocompromised, and patients with malignancies or HIV infection. Objectives: The phenotypic screening of metallo beta-lactamases (MBL) in strains of Pseudomonas aeruginosa resistant to imipenem. Material and Methods: The study was carried out in the department of Microbiology, in a medical hospital, Bareilly, over a period 18 months from January 2013 to June 2014. A total of 103 Pseudomonas aeruginosa isolated from sputum, broncho alveolar lavage (BAL), urine, pus and blood from critically ill patients admitted in the intensive care unit of a tertiary care centre. Strain of P. aeruginosa resistant to imipenem, were tested for metallo beta-lactamase production by phenotypic methods. Result: Out of 103 Pseudomonas aeruginosa, 48 strains were found imipenem resistant, of which 43(89.6%) were MBL positive by imipenem -EDTA combined disc test and the rest 35(72.9%) were by modified Hodge test. Conclusion: Imipenem – EDTA combined disc test found to be the best phenotypic method for detection of MBL. The appearance of the MBL and their spread among bacterial pathogens is a matter of concern with regard to the future of antimicrobial therapy. Both the methods are simple and one of these phenotypic methods can be easily incorporated in routine lab procedures to detect MBL

Biochar Synthesis from Mineral- and Ash-Rich Waste Biomass, Part 1: Investigation of Thermal Decomposition Mechanism during Slow Pyrolysis

Synthesizing biochar from mineral- and ash-rich waste biomass (MWB), a by-product of human activities in urban areas, can result in renewable and versatile multi-functional materials, which can also cater to the need of solid waste management. Hybridizing biochar with minerals, silicates, and metals is widely investigated to improve parent functionalities. MWB intrinsically possesses such foreign materials. The pyrolysis of such MWB is kinetically complex and requires detailed investigation. Using TGA-FTIR, this study investigates and compares the kinetics and decomposition mechanism during pyrolysis of three types of MWB: (i) mineral-rich banana peduncle (BP), (ii) ash-rich sewage sludge (SS), and (iii) mineral and ash-rich anaerobic digestate (AD). The results show that the pyrolysis of BP, SS, and AD is exothermic, catalyzed by its mineral content, with heat of pyrolysis 5480, 4066, and 1286 kJ/kg, respectively. The pyrolysis favors char formation kinetics mainly releasing CO2 and H2O. The secondary tar reactions initiate from ≈318 °C (BP), 481 °C (SS), and 376 °C (AD). Moreover, negative apparent activation energies are intrinsic to their kinetics after 313 °C (BP), 448 °C (SS), and 339 °C (AD). The results can support in tailoring and controlling sustainable biochar synthesis from slow pyrolysis of MWB
