Adsorbents
for pesticide uptake from contaminated water: A review |
This review provides applications of conventional and non-conventional
adsorbents for removal of pesticides from wastewaters. The data presented are
mainly based on laboratory studies and show potential advantages for
treatment of pesticides bearing wastewater by various adsorbents. |

Remote monitoring system for distributed control of
industrial plant process |
This paper proposes a remote monitoring system as part of Distributed Control System (DCS) of process plant. Remote plant critical alarms from DCS are continuously monitored online through Supervisory Control and Data Acquisition (SCADA) system. A report, which contains alarm details formulated through MS-Excel, is sent to respective e-mail recipients through Outlook Express. For system maintenance, M2M gateway and Virtual Private Network (VPN) technology are used in remote monitoring.

Experimental investigation of a novel heat pipe cold plate for
electronics cooling |
In this study, to deal with multi-heat-source and high-heat-flux heat transfer problem in confined space within electronic equipments, cold plate equipment employing heat pipe technology has been designed. Acetone-aluminum heat pipe construction composed of 8 vertical pipes with their upper condensation section and lower evaporation section connected to let working liquid and vapor flow through each other when equipment works. Heat pipe cold plate equipment has been formed and possesses excellent heat-transfer performance, startup performance and temperature evenness and can solve high heat-flux problem determining working reliability of array antennas effectively. |

Analysis of ECG signal by
chaos principle to help automatic diagnosis of myocardial infarction |
Chaotic behavior of electrocardiogram (ECG) signal of myocardial and non-myocardial infarctions is differentiated using neuro-GA approach, incorporating heuristically chosen phase space fractal dimension (PSFD) of ECG data. A remarkable improvement of diagnostic efficiency, sensitivity and specificity was observed in case study.

Entrainer for batch
distillation of acetic acid –water system |
Acetic acid–water system (AW) poses a challenge in reactive distillation, acetic acid purity and loss of acetic acid in aqueous solutions. Feasible separation of AW has been studied using entrainers but acetic acid loss in lean phase cannot be avoided. This study presents feasible region to operate column with toluene and benzene as entrainer for AW. Liquid -liquid equilibrium data and nature of tie line for ethyl acetate are given priority.

Characterization of a
partially purified bacteriocin of Bacillus
sp MTCC 43 isolated from
Rhizosphere of radish (Raphanus
sativus) & its application as a potential food biopreservative |
This study presents bacteriocin, produced from Bacillus sp. MTCC 43 isolated from rhizosphere of root crop radish, Raphanus sativus, as inhibitor against serious food pathogens (Staphylococcus aureus and Aeromonas hydrophila). Bacteriocin of Bacillus sp. MTCC 43, partially purified by salt saturation method, exhibits very high activity (2.66 x 105 AU/ml). Viability of pathogens decreased drastically (up to 70%) within first 10 h of adding bacteriocin. Bacteriocin showed high thermostability (up to 100°C) for 10 min, expressed wide pH tolerance (4.0-10.0), and found sensitive to proteolytic enzyme trypsin.

Utilization
of biomass as engine fuel |
In this study, performance of gasifier engine system is analyzed by running 5kW engine at different load conditions to check maximum diesel savings in dual fuel mode operation. Cotton stalks replaces diesel by 80% while sugarcane bagasse replaces it by 82%. By using appropriate agricultural residue, gasifier system integrated with CI engine is economically better than diesel system alone.

Effect
of photosensitizers and inorganic ions on hydrogen generation from hydrogen
sulfide |
This study presents hydrogen (H2) generation from hydrogen
sulfide (H2S) using photocatalyst [(CdS/ZnS)/Ag2S+(RuO2/TiO2)]
with photosensitizers (Rhodamine B, Eosin Y, Methylene Blue and Methyl
Violet). In presence of Rhodamine B, photocatalyst yields 1.3 times more H2
than control. In presence of anions (I-, Cl-, NO3-,
CO32- and SO42-) and cations (Fe3+,
Cu2+), photocatalyst yields less H2.

Adsorptive removal of Reactive and
Direct dyes using non-conventional adsorbent – Column studies |
This study presents effect of influent concentration, flow rate and bed height on packed bed column prepared by Euphorbia antiquorum L activated carbon used for adsorptive removal of dyes, Reactive Red 4 and Direct Blue 53. Adsorption efficiency increases with increase in influent concentration and bed depth and decreases with increase in flow rate. Yoon-Nelson model described adsorption behaviour of selected adsorbent-adsorbate system more reasonably than Thomas model and Reactive Red 4 adsorption behaviour fits exceptionally well with Yoon-Nelson model.

Biodegradation kinetics of benzoic and
anthranilic acids by Micrococcus sp.
Karuppan Muthukumar*, Chakravarthy Bharath, Velan
Pugalenthi and Manickam Velan |
This study presents biodegradation of benzoic acid (BA) and
anthranilic acid (AA) by Micrococcus sp. under aerobic conditions.
Initial concentrations of BA and AA were varied (500-2500 mg/l) and almost
complete biodegradation of BA and AA was observed within 30 h. Andrews
kinetic model for single substrate was fitted to obtain maximum specific
growth rates, half saturation and substrate inhibition constants. Cell growth
with degrading BA (μm,BA = 0.645 h-1) was faster
than with degrading AA (μm,AA = 0.63 h-1). Under
biodegradation of BA and AA, first order rate constant values decreased with
increase in initial concentration.
