Ayurvedic Bhasma: the most ancient application of nanomedicine





Prasanta Kumar Sarkar &
Anand Kumar Chaudhary

In practice of Ayurveda, herbo-mineral/metallic formulations (Bhasma of metals and minerals) are used since 7th centuries. It was supposed that these medicines have superior level of efficacy in comparison to other Ayurvedic dosage forms. Several studies claimed that Bhasmas are biologically produced nanoparticles.

Simulation and evaluation of a straight-bladed Darrieus-type cross flow marine turbine



























S Lain & C Osorio

This study presents numerical simulations of a cross-flow vertical-axis marine current turbine (straight-bladed Darrieus type) with particular emphasis on rotor-performance prediction and hydrodynamic characteristics. A physical transient-rotor-stator model with a sliding mesh technique was used to capture change in flow field at a particular time step. A shear stress-transport k-ω turbulence model was used to model turbulent features of the flow. Developed model can effectively predict hydrodynamic performance of a vertical-axis marine current turbine.

Numerical simulation of aluminum bar casting for wire rod production


















S P Mohapatra, S K Sahoo, S Nanda,
P Hembram, A Palchaudhary & S C Patnaik

In a continuous casting of wire rod production, a cast bar, which is formed in a rotating wheel mould, is subsequently rolled by a set of rolls to form wire rod. Temperature of cast bar predicted by model has been verified by actual temperature measurement during casting at different operating conditions. Simulation results show the influence of various operating parameters on temperature distribution of cast bar.

Extending tool-life through jerk-limited motion dynamics in machining processes: An experimental study
















J R Rivera-Guillen, R J Romero-Troncoso, R A Osornio-Rios, A Garcia-Perez &
I Torres-Pacheco

This paper analyzes jerk repercussion in tool life under an experimental study on a retrofitted CNC lathe, where a trochoidal geometry is machined. Results show an up to 60% tool-life improvement and 50% of surface roughness reduction when jerk-limited motion dynamics on machining process are utilized.

Solving an economic production lot size problem with multi-delivery policy and quality assurance using an algebraic approach





Yuan-Shyi Peter Chiu, Kuang-Ku Chen & Huei-Hsin Chang

This paper studies an economic production lot size problem with multi-delivery policy and quality assurance using an algebraic approach for practitioner, who may not have enough knowledge of differential calculus, to understand such an integrated production-shipment system. A recent study19 examined same problem using mathematical modeling and differential calculus to derive optimal replenishment lot size.

Model-based iterative feedback tuning for industrial PID controllers







M Milosawlewitsch-Aliaga, R A Osornio-Rios & R J Romero-Troncoso

This paper proposes a model-based iterative feedback tuning over a pseudolinear closed loop output error model basis. Its effectiveness is proven in an industrial level-control system.

A novel software architecture for smart metering systems























Srđan Vukmirovic, Aleksandar Erdeljan, Imre Lendak & Darko
Čapko

For smart metering systems (SMSs), this study presents a novel architecture, which allows simple, secure and fast integration of SMSs with other software products. Proposed architecture that combines better features of two models [Common Information Model (CIM) and OPC’s Unified Architecture (UA)] has proven in practice as a good basis for a commercial Meter Data Management System.

Microbial tannase, a hydrolysable tannin-degrading enzyme, is extensively used in manufacture of instant tea, beer, wine, and gallic acid. Aspergillus niger strain, obtained from a Mexican tannery wastewaters rich in gallic acid [Quebracho Phenolics-rich Tannery Wastewaters, (QPTW)], displayed a good growth and tannase activity in a minimal medium added with 1% (w/v) QPTW (Kr= 0.451 mm.h-1). Using PCR and RACE 3´ and 5´methodologies, a complete cDNA of a tannase was cloned from this isolate. A. niger-GTO is a new strain with interesting characteristics for industrial tannase production purposes.

Potential of thermophilic bacteria as microbial inoculant for commercial scale white button mushroom (Agaricus bisporus) compost production








O P Ahlawat & B Vijay

Thermophilic bacteria (9), isolated from button mushroom (Agaricus bisporus) compost samples, were evaluated for temperature requirement, extracellular lignocellulolytic enzymes activity assay and potential for white button mushroom compost production. Optimum growth in different bacteria was between 43-55°C. Highest activity of exoglucanase and endoglucanase was recorded in Staphylococcus sp., while that of b-glucosidase in Bacillus brevis and B. megaterium, and xylanase as well as laccase in B. stearothermophilus. Staphylococcus sp. also exhibited second best activity of xylanase. Compost prepared with Staphylococcus sp. exhibited highest colony forming units of bacteria, numbers of mushroom pinheads and mushroom yield. Thus Staphylococcus sp. has potential to convert agro wastes into selective and productive compost for white button mushroom cultivation.

Formulation and quality assessment of instant dhokla mix with incorporation of pumpkin flour














Usha Ravi, Lakshmi Menon & M Anupama

This study presents an instant dhokla mix with incorporation of pumpkin (Cucurbita moschata) flour at 10, 20 and 30% levels in instant mix. Incorporation of pumpkin powder in instant dhokla mix resulted in a significant increase in nutrients (threefold increase in protein and twofold increase in fiber). Beta-carotene levels of dhokla mix increased by 8.4% in 20% pumpkin flour incorporated dhokla mix when compared to standard.

A new approach for jute industry to produce fancy blended yarn for upholstery




















Surajit Sengupta & Sanjoy Debnath

This study presents a new approach to make jute based yarn by blending polypropylene in jute (30:70) in jute finisher drawing. Fabric has been made in specially modified handloom. Developed fabric showed higher area density, thickness, and weft crimp, tenacity and rigidity and it was cheap than commercial fabric. It was dimensionally and quality wise stable after wash, and showed no visible deterioration or deformation including surface texture, when used as table cloth and bed cover for two months.

Forced convection flat plate solar air heaters with and without thermal storage


















P T Saravanakumar & K Mayilsamy

This paper presents thermal performance of flat plate solar air heater (SAH) with and without thermal storages. A forced convection solar collector (FCSC) integrated with different sensible heat storage material has been developed and tested for its performance for solar collector under meteorological conditions of Aliyar, Pollachi Taulk, India. System consists of a flat plate SAH with heat storage unit, and a centrifugal blower to increase collector outlet temperature and efficiency (10-20%). Gravel with iron scraps gives better efficiency than other storage materials. FCSC is more suitable for drying high quality dried product even in a cloudy climate like Pollachi.
