In the present study, Turmeric oil was efficiently extracted from turmeric seeds in a pilot scale unit using R134a (1,1,1,2tetrafluoroethane) as a solvent. The effect of operating parameters (Pressure of solvent, average particle size of feed and time of extraction) on % extraction of oil was studied. Maximum oil yiel…
This paper report the simulation results for annealed glass subjected to air blast loading. In this research, 8 mm and 12 mm thick annealed glass was subjected to blast with a charge weight of 2kg and 5kg of TNT at a standoff distance of 3.0 meter. AUTODYN 3D hydrocode simulation software was used to simulate the beha…
Hydrogen sensing and photoelectric properties of a graphite/ZnO nanorods (NRs) junction were investigated. The graphite/ZnO NRs junction was prepared by low temperature hydrothermal growth and deposition of colloidal graphite. The proposed hydrogen sensor showed response to 1000ppm hydrogen in nitrogen even at room te…
Power quality standards (IEEE-519) compel to limit the total harmonic distortion within the acceptable range. Hybrid filter which has been used to monitors the load current constantly and continuously adapt to the changes in load harmonics. The power filter is consisting of a shunt passive filter connected in series w…
Effect of load ,sliding velocity ,material ,hardness of disks and roughness of the sample surface on coefficient of friction and wear rate were studied in this work .Pin on disk technique was used to satisfy the required aims ,and the testing samples were subjected to various conditions of velocities and loads. The re…
Objective: The purpose of this study was to express and purify recombinant anti-thrombin in Saccharomyces cerevisiae BY4741 expression system. Methods: cDNA of human anti-thrombin gene was amplified with specific primers and cloned into pYES2/CT vector with His-tag for easier purification using Ni2+ Results: Protein w…
Design and development of sensor system for the measurement of impact load due to canister collapse at sub sonic speeds in a compressed air operated bird/ice pellet launcher.this experiment is carried out to find impact of canister on canister arrester. Canister is a device which cup shaped structure front side is ope…
Society’s perceptions of desired democratic standards in radioactive waste management sector have changed significantly in the recent two decades. The change, known also as ‘participatory turn’, can be well illustrated on the example of site selection process for a geological repository of spent nuclear fuel in the Cz…
High temperature polymeric materials for electrical insulation and energy storage are needed for transformational power applications such as pulsed-power and hybrid electrical vehicles. One of the candidate materials has been polyetherimide, an amorphous thermoplastic with a glass transition over 200 o C. Here, the di…
The effect of solvent (water), power, time of microwave exposure and maturity stage of the orange fruit on the essential oil extraction yield and its chemical characteristics and on the pectin extraction yield from Valencia orange peels was studied. The extraction of essential oil by microwave and subsequent extractio…
A novel Er complex C14H11ErN2O10â4(H2O) has been synthesized from a hydrothermal reaction and the crystal structure has been determined by means of single-crystal X-ray diffraction. Monoclinic, P21/c. a=14.0400(10) A, b =11.2536(9) A, c =12.9373(9) A, α= 90°, β=102.010(6) °, γ=90°. V=1999.4 A3. Z=8. R1 =0.0586, wR2…
The research of new pi-conjugated molecules with specific applications has become one of the most interesting topics in the fields of chemical physics and materials science. Thanks to their specific properties, these compounds have become the most promising materials for the optoelectronic device technology such as so…
The interaction of polyphenylsiloxane with tungsten oxide(VI) in conditions of mechanochemical activation has been studied. The polytungstenphenylsiloxanes have been prepared with the yields from 43.3 to 44.8% with the activation time of five or three minutes, respectively. The relation Si/W (9.2-9.3) has been prepare…
Drug delivery systems (DDS) are vital for treatment of virtually all disease states. A multitude of systems exist, but nanoparticle (NP) based delivery vehicles have been a primary focus among researchers. More recently, a process to coat nanoparticles with plasma membrane from human cells was developed and, thus, mem…
Magnetization measurements have been performed on Co II , Co III and Co II−III incorporated into carbosilazane-based polymeric matrix (PEDCSZ, -((CH3)2SiNHCH2CH2NH)n--). The local field effect has been evaluated using simple approach similar to the Weiss molecular field model in the paramagnetic state. In this approac…
The article presents the results of research on the production co-crystallisates of cyclic nitramines (RDX, HMX, BCHMX, HNIW) with polar solvents containing different complexing groups, including the solvents of the class of linear nitramines. We identified some characteristics of co-crystallisates obtained by differe…
In this paper the solubilities of the amino acid, DL-α-amino butyric acid (Aba) were measured in aqueous solution with various sodium chloride (NaCl) concentrations. The solubilities were measured by ‘formol titrimetry’ method in the temperature range from 288.15 to 308.15 K. The standard transfers Gibbs energies and…
Three series of polybenzimidazole (PBI) copolymers (3,5pyridine-r-2OH-PBI, 3,5-pyridine-r-para-PBI, and 3,5-pyridine-r-meta-PBI) were polymerized and cast into membranes by the polyphosphoric acid (PPA) process. Monomer pairs with high and low solubility characteristics were used to define phase stability-processing w…
Hyperlipidemia or hyper lipoproteinemia or dyslipidemia is the presence of elevated or abnormal levels of lipids or lipoproteins in the blood. Lipid and lipoprotein abnormalities are extremely common in general population and are regarded as a highly modifiable risk factor for cardiovascular diseases due to influence…
Despite increased nanoresearch, the influence of nanoparticles on the immune system is still poorly understood. Recently we demonstrated ex vivo modulation of T lymphocytes from aged mice post exposure to a mixture of nanodiamond (ND) and nanoplatinum (NP) coated material (DPV576-C). Here, we extend our study to exami…
