The present study analyses the potential of groundnut shell to produce combustible gas in a fluidized bed gasifier. The goal of the study is to investigate the effects of reactor temperature and steam to biomass ratio on gas composition of the product gas with gas yield. The experiments are performed in the temperatur…
Silver and gold nanoparticles were prepared by using nanosecond pulsed laser ablation. Ablation of pure metal targets (Ag and Au) for nanoparticle colloidal production was studied in de-ionized water. The optical properties were studied with Ultraviolet- Visible (UV-Vis) spectrophotometer. The spectra reveal sharp pea…
One of the important applications of nanotechnology in the medical field is the use of it in drug delivery to target tissue for therapy of disease such as diabetes. Despite the limitations in the use of traditional medicine systems, there are also lack of target specificities, which reduce the effects of compounds due…
With obesity becoming a major health issue in recent years and a topic of interest in vehicle occupant safety, there is a need for detailed descriptions of body fat distribution in order to develop accurate models of the human body. In this study subcutaneous fat measurements were obtained from over 17,000 CT scans us…
2 Abstract: Transformers are conventionally designed for operation under sinusoidal load currents with supply voltage-frequency. The non-sinusoidal or harmonically distorted currents drawn by non-linear loads lead to excessive winding losses and overheating of the transformers. These adverse effects result in loss of…
The term ‘cloaking’ in the linearised water wave context has been used to describe the process by which a structure subject to small amplitude time-harmonic incident waves is rendered invisible to the observer in the far field by the addition to/alteration of the geometry in a finite region outside that structure. Thu…
In this paper, our goal is to determine sufficient conditions for the family of Struve functions in order to belong to the classes of uniformly convex functions and uniformly starlike functions in the open unit disk U. Several corollaries and consequences of our main results are also derived.
Titanium dioxide(TiO2)thin films were synthesized via sol-gel spin coating method using titanium tetra isopropoxide (TTIP) as starting material. TTIP is dissolved in ethanol stabilized by glacial acetic acid. TiO2 thin films were prepared for different proportions of acetic acid. The prepared samples were dried at 250…
Uracil is an essential biomolecule for terrestrial life, yet its prebiotic formation mechanisms have proven elusive for decades. Meteorites have been shown to contain uracil and the interstellar abundance of aromatic species and nitrogen-containing molecules is well established, providing support for uracil's presence…
Enantioselective hydrogenation of tiglic acid effected by diastereomers of the general formula [(μ-H)2Ru3(μ3-S)(CO)7(μ-P-P*)] (P-P* = chiral Walphos diphosphine ligand) strongly supports catalysis by intact Ru3 clusters. A catalytic mechanism involving Ru3 clusters has been established by DFT calculations.
Cocoyam (Colocasia esculenta) flour was cooked and extruded in a single screw extruder (DD85G, 201132, IBG Monforts Gmbhi & Co, D-4050 Monchengladbach, Germany). A second order central composite response surface design was adopted in designing the experiment which generated 20 runs on selected process parameters inclu…
The following article presents results of examination of the resistance of the special electrodes made with using vacuum technology. These electrodes can be a item of clothing and can be used for electrical stimulation and monitoring of physiological parameters. The discussion of the discrepancies of e-fiber resistanc…
One of the energy-minimum structures predicted by the intermolecular interaction potential energy surface computed using the M062x/6-31G** method closely resembled the crystal packing.

The selective dissolution of cobalt and the consequent surface enrichment of platinum in Pt–Co binary alloys immersed in 0.5 mmol·m−3 H2SO4 at 298 K were investigated. Four different Pt–Co alloy thin films with various Pt contents, deposited on glassy carbon sheets by physical vapor deposition, were investigated: 51 a…
We examined the influence of the properties of macromolecular carbon on thermochemical de novo synthesis of toxic chlorinated aromatic compounds (aromatic-Cls), such as polychlorinated dibenzo-p-dioxins (PCDDs), furans (PCDFs), biphenyls (PCBs), and chlorobenzenes (CBzs). Six types of macromolecular carbons were prepa…
BACKGROUND: It is urgent to find alternative agents due to increasing failure rate of Helicobacter pylori (H. pylori) eradication. The study surveyed the long-term effect of silver nanoparticles (AgNP) on H. pylori based on Mongolian gerbil's model. MATERIALS AND METHODS: Fifty gerbils were randomly allocated to six g…
Advances in probes for cellular imaging have driven discoveries in biology and medicine. Primarily, antibodies and small molecules have been made for contrast enhancement of specific proteins. The development of new dendrimer-based tools offers opportunities to tune cellular internalization and targeting, image multip…
This paper studied the use of waste chicken feather as reinforcement in cement bonded composites.
Nanocomposite hydroxyl apatite phase of calcium phosphate powder has been successfully synthesized employing coprecipitation technique. Structural characterization utilizing X-Ray Diffraction, SEM and FTIR techniques was achieved. To confirm the thermal stability of the obtained powder TGA and DSC measurements over wi…
