Introduction: Object sorting has become an essential-criterion in all the industries across the world. Automated industries employ several methods for establishing perfect object classification. In this fast-moving modern era, even every small-scale industry is in need of a system for sorting the goods they produce.
Objective: Objective of this study was to classify objects based on color using the sensor TCS3200 in a perfect way.                                                                                                                                    Materials and Methods: Color based object sorting is an effective way to distinguish the objects using some comparatively convenient techniques. This paper introduces two efficient methods for classifying objects based on color. The first technique implies electrical actuation using DC servo motors and the second method used pneumatic actuation for sorting. Both the methods use TCS3200 as the primary sensor for classification of objects.                                                                                                             Results: Both the methods proved to be effective by accurately recognizing the input objects and classifying them in an excellent way as instructed.                                                                             
Conclusion: These methods can be implemented to any kinds of industrial sorting irrespective of the size and shape of the objects. These most cost-effective and user-friendly ways to separate objects based on color.

Eyes  are  the  sensitive  body  part  that  require  attention, care and safety if  we wish them to work efficiently and last long for a proper vision. Vision impairment, eye diseases and disorder have astrological relevance. The paper elaborates the scientific narrative of medical astrology research. The condition of eyes of a native depends upon the status of Ketu and benefic or malefic planetary influence on second and twelfth house in the horoscope (Lagan and Navmansh) of a person. The factors influencing the impairment, disease and disorder of eyes have been discussed in the paper.

A proposed hybrid system based on diesel generator and solar photovoltaic (PV) as an effective option to power Mkpok Housing estate in Eket has been presented in this work. Running diesel generator constantly in the estate due to epileptic electricity supply from Power Holding Company of Nigeria (PHCN) is very expensive and not eco-friendly. The main objective of this proposed system is optimal design of a solar PV powered supply system to produce sustainable power and reduce or augment the use of continual diesel generator sets, resulting in reduced cost of operation, maintenance and pollutant emissions. Solar radiation data was obtained from meteorology station, analysis, proper sizing and specification of the PV system and battery bank were done based on this information. The hourly solar radiation, calculated values were considered, and used as input of the Hybrid Optimization Model for Electric Renewable (HOMER) software to analyze the system. In addition, a comparative study was carried out considering two scenarios of the proposed model system. In the first scenario, the diesel generation, solar PV system was treated as autonomous (or standalone). In the second scenario, the proposed model system was connected to the grid system. It is found that electrifying the housing estate using the proposed hybrid system is very beneficial and competitive with other types of conventional sources due to the fact that it decreases both operating costs and pollutants emissions. Also, results from the HOMER software are realistic and give promising results for on-grid schemes.

L-Ascorbic acid is a versatile integrant that is found in abundance in nature and can be easily isolated. It has numerous applications due to its salubrious virtue and commercially effectual usage. The review is a concise narrative to its commercial viability.

Introduction: Giant cell tumor (GCT) is a benign bone tumor but known for its locally aggressive nature and high recurrence rate. Also, it has high rate of complications like pathological fracture, malignant change, pulmonary metastasis.
Case Details: A 32year old male presented with history of pain, swelling and inability to bear weight after a fall. He was previously treated for GCT of distal end femur by intralesional curettage and cementing. X ray showed a recurrent GCT with intra articular pathological fracture. Wide local resection with reconstruction by megaprosthesis was done.
Conclusion: Wide local excision with reconstruction by megaprosthesis offers best solution for a recurrent GCT with intra articular fracture with wide soft tissue involvement.
