Applicability of carboxydotrophic bacterial carbon monoxide dehydrogenase (CODH) in carbon sequestration and bioenergy generation




This review presents applicability of carboxydotrophic bacterial carbon monoxide dehydrogenase (CODH) in carbon sequestration and bioenergy generation. CODH catalyzes reversible conversion of CO2 to CO. These bacteria use CO and CO2 as source of energy and carbon for growth, and therefore, play a vital role in maintaining very low CO level in the environment. The enzyme finds application in detection and mitigation of CO levels, and also to produce bioenergy from CO2.

Energy anomaly detection in tire curing by using data integration and forecasting techniques













Hai-dong Yang, Jian-hua Guo &
Guo-sheng Liu

This study proposed a method of energy anomaly detection by using data integration and forecasting techniques to improve energy efficiency in tire curing. Compared with traditional method, proposed method is robust against environment changes, highly correlated to curing process and can discover curing energy anomalies (leakage of steam or nitrogen, idling, and improper curing parameters configuration) effectively.

Simultaneous detection of free polyethylene glycol and PEGylated proteins by western blot




















Krishna Tiwari, Sunil Shebannavar,
Krishna Kattavarapu, Santosh Pokalwar, Maheshwari Mishra &
Ugam Kumari S Chauhan

This study presents detection of free polyethylene glycol (PEG) and conjugated PEG in western blot assay using anti-PEG rabbit monoclonals specific to methoxy group of PEG. In a chromogenic western blot assay, detection limit (DL) for free and PEGylated protein was 2.5 g and 0.5 g, respectively. Using chemiluminescence substrate, DL of PEGylated granulocyte colony stimulating factor (GCSF) was 100 pg. Assay applied to PEGylation reaction mixture detected both free and PEGylated protein. Commercially available PEGylated products using western blot assay revealed pharmacologically pure preparations.

Biosurfactant production by Bacillus subtilis TD4 and Pseudomonas aeruginosa SU7 grown on crude glycerol obtained from biodiesel production plant as sole carbon source






















Atipan Saimmai, Onkamon Rukadee, Vorasan Sobhon & Suppasil Maneerat

This study presents isolation of biosurfactant (BS)-producing bacteria, Bacillus subtilis TD4 (BsTD4) and Pseudomonas aeruginosa SU7 (PaSU7), from palm oil contaminated soil. BS production was done by using a minimal salt medium with used crude glycerol as carbon and commercial monosodium glutamate as nitrogen source. BS produced by BsTD4 exhibited higher oil recovery efficiency than that produced by PaSU7. Both BSs could recover oil more effectively than synthetic surfactants, could enhance solubility of PAHs, and can emulsify various oil and hydrophobic compounds.

Sustained stomach specific delivery of piroxicam from floating emulsion polyelectrolyte complex beads

























Anurag Verma, Raghav Dixit &
Jayant K Pandit

This study presents development of floating emulsion polyelectrolyte complex (PEC) beads based on gellan-chitosan PEC and Gelucire 39/01 and 50/13 without using any chemical crosslinker, and release from developed beads of piroxicam (PRM) in 0.1 M HCl (pH 1.2). Developed beads showed excellent buoyancy, significantly improved encapsulation efficiency and sustained release of PRM compared to floating gellan-chitosan beads bearing PRM. Thus emulsion PEC beads may form a potential stomach site specific drug delivery system for PRM delivery

Formulation and evaluation of sublingual tablets of lisinopril






















Ish Grover & Gaurav Agarwal

This study presents formulation and evaluation of sublingual tablets of lisinopril for treatment of hypertension. Sublingual route offers faster disintegration and dissolution of drug than oral route, because of increasing bioavailability as it bypass GIT (gastro intestinal tract). Sublingual tablets, prepared by direct compression method, were found in accordance with standards. Out of three batches (A, B, C), batch B having fastest disintegrating time was most suitable as sublingual tablet.

A Sliding Mode Multimodel Control for a Sensorless Photovoltaic System






This study presents a sliding mode multimodal control for a sensorless photovoltaic panel, which sets itself as per the sun position at every second during the day for a period of five years; then tracker, using sliding mode multimodal controller and a sliding mode observer, will track these positions to make sunrays orthogonal to photovoltaic cell that produces more energy. After sunset, tracker goes back to initial position of sunrise. This autonomic dual axis sun tracker increases power production by over 40%.

Pressure distribution of rotating small wind turbine blades with winglet using wind tunnel























P Saravanan, K M Parammasivam &
Selvi Rajan

This study presents pressure distribution over an envelope of blade with and without winglets for a small wind turbine in boundary layer wind tunnel. Different winglet configurations were tried based on winglet height and curvature radius. Pressure measurements were made with different chordwise and spanwise locations on the blade with and without winglets nearby tip region. Winglet improves overall pressure difference between pressure surface and suction surface. Presence of winglet seemed to have the pressure increased at 0.3c and maximum pressure difference was observed at a span of 0.95R for all winglet configurations. In suction, surface pressure decrease was 10% for all winglet configurations.

Comparison of polycyclic aromatic hydrocarbons emission from thermal treatment of petroleum sludge cake in the presence of different additives















Edward Nixon Pakpahan, Mohamed Hasnain Isa,
Shamsul Rahman Mohamed Kutty, Somporn Chantara, Wan Wiriya & Ibrahima Faye

This study evaluates effectiveness of 4 additives [CaO, Ca(OH)2 + NaHCO3, H2O2, and FeSO4 + H2O2] in thermal degradation of hazardous polycyclic aromatic hydrocarbons (PAHs) in petroleum sludge cake. Residual concentrations of 16 priority PAHs were determined using GC-MS. Total PAH conc. was found as: gas, 3.11 10-4 - 4.36 10-4 ppmv; particulate, 7.92 10-5 - 5.24 10-4 mg/m3; and residue, 1.37 10-4 - 1.07 100 g/g. Total toxicity equivalence of PAHs relative to that of benzo[a]pyrene (BaP) was found as: gas, 3.11 10-7 - 4.41 10-7; particulate, 3.87 10-7 - 3.85 10-5; and residual, 6.17 10-7 - 9.65 10-3. Ca(OH)2 + NaHCO3 was most suitable due to least emission of high molecular weight PAHs, lower equivalent carcinogenicity of products, and lower concentrations of PAHs in gas, particulate and residue.

Reclamation of dye wastewater using a flat sheet nanofiltration membrane: Study of permeate flux and quality

















Tejal M Patel, Tanya Roy, Ankita Mishra & Kaushik Nath

This study presents treatment of dye containing wastewater in a nanofiltration pilot plant using hydrophilized polyamide membrane of flat sheet module. Permeate flux (PF) decreased with time of operation due to concentration polarization. Effect of trans-membrane pressure (TMP) showed a quasi-linear increase in flux with increasing pressure. PF (1.44 10-6 m3/m2.s) at 5 kg/cm2 was enhanced as PF (1.62 10-6 m3/m2.s) at 10 kg/cm2. Flux increased considerably with increase in dilution of wastewater. Maximum PFs obtained with 5 fold and 10 fold dilutions were 3.95 10-6 and 7.06 10-6 m3/m2.s respectively. Substantial removal of colour (98.3%) was achieved with a marked reduction in COD (89%) and TDS (77.2%).
