Management of waste poly vinyl chloride
(PVC) through chemical modification
|
This review presents a strategy for management of poly vinyl
chloride (PVC) waste by chemical modification as a viable method. PVC
contains chlorine as a source to attack by nucleophiles (Nu-) and resultant
product can be used for various applications due to its conductivity,
antibacterial and ion exchange properties. Prominently used Nu-
are I-, SCN-, OH-, N3-,
phthalimide anion and concentrated alkali solution in the presence of O2
as oxidants. |

Three dimensional nuchal translucency
assessment using magnetic resonance reconstruction imaging |
This study presents an open-source 3D
reconstruction and visualization technique using Visualization Toolkit (VTK)
on magnetic resonance image (MRI) for Nuchal Translucency (NT) assessment.
Real time 3D reconstruction model can be achieved through a series of
computation processes, which include DICOM (Digital Imaging and Communication
in Medicine) sources manipulation, grey interpolations, ray casting, color
and opacity transfer function, and volume rendering. Experimental simulations
show that 3D measurements of NT provide higher accuracy and consistency of
thickness measurement.

Ultrasonic signal compressive detection with sub-Nquist sampling rate |
This study presents a
compressed sensing (CS) based sampling approach for repetitive ultrasonic
signal. Proposed system considers recovering ultrasonic signal with high
equivalent sampling frequency from samples captured using analog-to-digital
converter (ADC) clocked at a rate lower than Nyquist rate. A basis function
is constructed to realize ultrasonic signal sparse representation, which
paves the way for applying CS theory to ultrasonic signal sub-Nyquist
sampling. A sampling architecture, applicable for ultrasonic compressive
detection, is developed. With this sampling system, an ultrasonic signal
sampled at ultra-low rate, but still can be recovered with overwhelming
probability.

Optimization of extraction
conditions of total phenol from lotus (Nelumbo
nuficera Gaertn) rhizome
|
Operating
factors affecting yield of total phenol and ferric reducing antioxidant power
(FRAP) value of extracts from lotus rhizome were studied by orthogonal design
experiment (L9(34)) based on single factor experiments.
Optimum extraction conditions on yield of total phenol were found as follows: ratio of material to liquid, 1 g: 6 ml; extraction
temperature, 70 oC; extraction time, 2 h;
and ethanol concentration, 40%. For FRAP value, optimal parameters were as follows: ratio of material to liquid, 1 g: 8 ml; extraction
temperature, 50 oC; extraction time, 0.5 h; and ethanol
concentration 40%.

Comparative
evaluation of various sorbent decontaminants against sulphur mustard |
This
study evaluates sorbent decontaminants [fullers earth (FE) , fast act (FA),
activated alumina (AA), mixed oxide aerogel Al2O3-CuO
(MOA), nanosized TiO2 (NT)] for physical removal efficiency and
chemical reactivity using gas chromatography against sulphur mustard (HD)
contaminated surfaces of glass, metal, painted metal, and rubber. NT
exhibited superior physical removal efficiency and chemical reactivity
against HD, thus proving as potential sorbent decontaminant against chemical
warfare agent (CWA) spills.

Analysis of femoral trochanters morphology based on geometrical model
|
This
study presents morphological analysis of 20 scans of femur samples from
European (Serbian) adults from trochanteric region based on the customized
computer aided reverse modeling procedure. Results indicated that
trochanteric region is a separate morphological unit of proximal femur, named
trochanteric wedge or canoe. This new perceiving of trochanteric region seems
to provide a better understanding of trochanteric wedge volume and, therefore,
better trochanter fractures treatment, operation planning, implant and
endoprothesis design and selection. Also, it brings a new light to anatomy of
proximal femur, its biomechanics and ossification.

Biogas production
through mixed fruit wastes biodegradation |
This study presents biogas production from fruit wastes at ambient
temperature using anaerobic batch digester (500 ml). Co-digestion of fruit
wastes were carried out with rice bran and cow dung. Biogas production from
different samples was as follows: Sample A (fruit waste), 363; sample B
(fruit waste, 75% + cow dung, 25%), 405; sample C (fruit waste, 75% + rice
bran, 25%), 315; and sample D (fruit waste, 50% + rice bran, 25% + cow dung,
25%), 381 ml. From chromatographic studies, sample B has maximum methane
content (80%) and sample C has maximum carbon-di-oxide content (50%). Cow
dung influences digestion of fruit wastes and showed highest yield (405 mg)
of biogas production.

Reduction of motor
fan noise using jute composites |
This study presents fabrication methodology of two
redesigned fans for noise reduction and improving cooling performance of baseline
fan (original configuration fan). These two redesigned fans (Fan-1 and Fan-2)
are fabricated using glass and jute fiber in propylene glycol resin by hand
lay-up technique.

Passive noise
control measures for traffic noise abatement in Delhi, India |
This study proposes a comprehensive noise abatement programme following the best practicable and economical option (BPEO) for implementation in metro city like Delhi for reducing annoyance and ill effects of traffic noise. It reviews potential applications of noise control barriers and vegetation for reducing road traffic noise and presents a design morphology and decision matrix using TOPSIS (Technique for order preference by similarity to ideal solution) approach for selection of appropriate sound barriers. |

Study on degradation of H-acid by Alcaligenes latus isolated from
textile industrial effluent |
This study presents 100% degradation of H-acid under optimized
conditions using Alcaligenes latus,
isolated from textile industrial effluent. Gene/s responsible for H-acid
degradation was/were found to be present on plasmid DNA. Addition of
bipyridyl to incubated medium resulted in accumulation of terminal aromatic
compound, suggesting that catechol may be terminal aromatic compound in
degradation pathway of H-acid by A.
latus. SDS-PAGE of cell free extracts showed two prominent bands close to
molecular weight of catechol 1,2-dioxygenase.
