Design of Journal Bearing Test Rig

Our study deals with a design of suitable test rig, which can help in determining the load bearing capacity, pressure distribution of a journal bearing. Present project work is about designing a test rig, which can be further utilized to check on the behavior of different materials as may be proposed in the design of journal bearing. Therefore the study involves theoretical aspects on the working principle of a journal bearing, numerical calculation and finally a 3D model of the test rig. The sole purpose of designing a test rig is to make it an economical design and yet fulfilling its purpose for conducting experiments. Realization of the project is achieved through 3D modeling and 2D drawing using Autodesk inventor. Test rig will allow the end user to visualize the behavior of any bearing under different working conditions

Meta-barcoding in combination with palynological inference is a potent diagnostic marker for honey floral composition

Abstract Identification of floral samples present in honey is important in order to determine the medicinal value, enhance the production of honey as well as to conserve the honey bees. Traditional approaches for studying pollen samples are based on microscopic observation which is laborious, time intensive and requires specialized palynological knowledge. Present study compares two composite honey metagenome collected from 20 samples in Mizoram, Northeast India using three gene loci- rbcL, matK and ITS2 that was sequenced using a next-generation sequencing (NGS) platform (Illumina Miseq). Furthermore, a classical palynology study for all 20 samples was carried out to evaluate the NGS approach. NGS based approach and pollen microscopic studies were able to detect the most abundant floral components of honey. We investigated the plants that were frequently used by honey bees by examining the results obtained from both the techniques. Microscopic examination of pollens detected plants with a broad taxonomic range covering 26 families. NGS based multigene approach revealed diverse plant species, which was higher than in any other previously reported techniques using a single locus. Frequently found herbaceous species were from the family Poaceae, Myrtaceae, Fabaceae and Asteraceae. The future NGS based approach using multi-loci target, with the help of an improved and robust plant database, can be a potential replacement technique for tedious microscopic studies to identify the polleniferous plants
