Banana serves as an ideal and low cost food source for developing countries where most of the population rely mostly on bananas for food. Banana plant parts are useful as insecticide, antioxidant, colour absorber, in preparation of various functional foods, wine, alcohol, biogas, cattle feed etc. This review discusses usefulness of banana fruits, peel, leaves, pseudostem, sheath, pith and male bud, and prospects of using these materials in industry.

This study evaluated status of telecommunication sectors in Central Asia comparing 6 countries with 62 countries in 6 regions (Africa, Central Asia, East Asia, Middle East, Europe, and South America) using DEA and ANOVA. Data using 7 IT indicators were collected and analyzed by DEA. This paper implements Knox’s corollary for DEA in assessment, ranking and optimization of telecommunication sectors. Principal Component Analysis (PCA) was applied to verify rankings of DEA. Central Asia was found at the bottom of all regions studied.

This paper presents an optimization feed rate technique for smooth trajectories generation based on polynomial interpolation. Proposed methodology implements constant or variable feed rate based on a reconfigurable FPGA. Experimental results verified proposed methodology with high efficiency for both approaches.

2Department of Production Engineering, National Institute of Technology, Tiruchirappalli 620 015, India

This paper presents development of neuro hybrid model (NHM) to predict weld bead width in submerged arc welding. Experiments were designed using Taguchi’s principles and results were used to develop a multiple regression model. Data set generated from Multiple Regression Analysis (MRA) was utilized in ANN model, which was trained with backpropagation algorithm in MATLAB platform and used to develop NHM to predict quality of weld. NHM is flexible and accurate than existing models for a better online monitoring system.

1Department of Mechanical Engineering, 2Department Automobile Engineering, PSG College of Technology, Coimbatore 641 004, India

This study presents hexagon and octagon cylinder models for effective thermal conductivity estimation of suspension system. Algebraic equations were derived based on isotherm approach for two dimensional spatially periodic medium. Model prediction was achieved with minimum (±10.83%) and maximum (±15.58%) deviation from experimental data for suspension systems. Model prediction was comparable with conventional models.

1Department of Manufacturing Design, Faculty of Manufacturing Engineering, Universiti Teknikal Malaysia, 76109, Durian Tunggal, Melaka, Malaysia

This study presents development of a new pump by modifying existing automotive spark plug, which is generally used for providing an electrode gap to produce an ignition in fuel-air mixture. Compressed air trapped between upper piston surface and spark plug was utilized by modifying spark plug design by implementing Pugh’s method.

A new method for spectrophotometric determination of colchicoside

A facile spectrophotometric method is proposed for determination of Colchicoside (COLSID) in bulk and in dosage forms using ceric ammonium sulphate (CAS). Method involves addition of a known excess of CAS to COLSID and determination of residual CAS with a fixed amount of either Azure B (AB), measuring absorbance at 633nm or Safranin O (SO), measuring absorbance at 519 nm. Calibration graphs are linear over 25.00-50.00 µgml-1, 22.00-38.00 µgml-1 and apparent molar absorptivity is calculated to be 2.28 x 104 l mol-1 cm-1 and 2.77 x 104 l mol-1 cm-1 for CAS-AB and CAS-SO respectively. Method is successfully applied to assay of COLSID in pharmaceutical formulations.

This study presents uptake of uranium (U) and thorium (Th) by live and dead cells of Pseudomonas Sp. Increasing concentration of U and Th showed decrease in absorption by Pseudomonas Sp. Dead cells of Pseudomonas Sp. exhibited same or more uptake of U and Th than living cells. Increasing temperature promotes uptake of U and Th by Pseudomonas Sp.

Antimicrobial properties of iodine based products

IO3- (100 ppm +) in water exhibits antimicrobial properties when taken alone or with salt. Polyiodide resin killed experimental bacteria on contact and exhibited excellent antimicrobial properties while resin loaded with IO3- was not effective. Therefore, polyiodide resin would be an efficient system for water disinfection.

Thumba (Citrullus colocyntis) seed oil can be used for production of biodiesel. A comparative experimental study, carried out on a four cylinder, direct injection, water cooled diesel engine operating on diesel and biodiesel blends (B10, B20 and B30) of C. colocyntis and Jatropha curcas, showed that like J. curcas, biodiesel of C. colocyntis can be used as an alternative fuel with better performance and lower emissions compared with diesel.

This study presents lignin extraction from commercial black liquor and utilizes it as a partial substitute in phenol formaldehyde (PF) resin synthesis. Characteristics of modified resin [non volatile solid content (<44%), alkalinity (<5%), pH (<11.6) and free formaldehyde (<1%)] were found close to control PF resin with a variable viscosity (418-781 cP). Shear test properties showed that phenol (15%) replacement with black liquor lignin produced comparable physical bond properties and could be used to formulate a low cost modified PF resin for plywood panels.

Physio-mechanical properties of particle boards from agro-wastes


This study presents particle boards made from low cost agro-wastes (date palm leaf and jute stick). Particle boards from jute stick, date palm leaf and their blends offered higher sound transmission loss, higher thermal insulation and lower swelling than plywood. Date palm leaf particle board showed highest strength, whereas board based on blend (1:1) of date palm leaf and jute stick gave highest impact strength.
