Supercritical carbon dioxide (sc2) is known as a good solvent for a wide range of bioactive compounds from natural sources. Extraction of bioactive compounds from plant material using sc2 is a favorable technique for producing solvent-free extracts suitable for a wide range of applications in pharmaceutical, biomedica…
We investigated co-precipitation using magnesium (Mg) salt as a cost efficient method of removing B from wastewater. To clarify the mechanism of co-precipitation and the effect of precipitation rate against B sorption mechanism, we conducted co-precipitation experiments changing reaction time at different temperatures…
GaN-based light emitting diodes (LEDs) as the third generation of lighting devices, have been rapidly developed in recent years. Substrate materials, serving as the LED manufacturing basis, have great influences on the production and application of LED. The critical characteristics of substrate affecting the design an…
One new oleanane-type saponin, 3-O-β-D-glucopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin 28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester (1) was isolated from the MeOH extract of whole plant parts of Cephalaria aristata C. Koch along with three known oleanan…
This paper presents the optimization of surface roughness & material removal rate in dry turning of SAE52100 steel. Carbide inserts were used for machining of SAE 52100 to study effects of process parameters [Cutting speed (S), Feed (F) and depth of cut (d)]. These models can be effectively used to predict the surface…
The generalized Hosoya triangle is an arrangement of numbers in which each entry is a product of two generalized Fibonacci numbers. We prove the GCD property for
Industrial use of azides requires special care to avoid explosions or poisonings. Life-cycle management of azide is discussed from the time azide-containing material is received at the front gate, sampled and stored, moved to the plant, placed in reactors, and finally until all wastes are abated and all equipment deco…
The effect of argon gas condensation (AGC) on crystallinity, surface morphology and photoelectrochemical (PEC) characteristics of SnSe thin films, prepared by thermal vacuum deposition onto ITO/glass substrates, has been investigated. The focal theme was to improve growth process of SnSe thin films and consequently en…
A finite element (FE) model is updated and optimized by making use of the surface temperature distribution captured with pulsed thermography (PT) on a PVC plate. The temperature distribution across the surface can be measured. As the amount of experimental data to be used in this case is very high, an accurate, time-e…
As we are faced with the exponential use of nanomaterials in consumer products, including food, the consequences of daily exposure to nanoparticles at low doses set public health issues for humans. Among the different routes of exposure, the oral route remains the less documented, although nanomaterials are commonly u…
Molten Salt Reactor (MSR) was selected as one of the six innovative nuclear reactors by the Generation IV International Forum (GIF). The circulating-fuel in the can-type molten salt fast reactor makes the neutronics and thermo-hydraulics of the reactor strongly coupled and different from that of traditional solid-fuel…
BACKGROUND: Drug-eluting stents (DES) with durable polymer have significantly reduced restenosis and target vessel revascularization compared with bare metal stents. Durable polymer has been linked with persistent inflammation of vessel wall and delayed endothelial healing that may increase the risk of late and very l…
Photodynamic therapy(PDT) is a promising new cancer treatment.This therapy involves the combination of a photosensitizer and visible light.When the photosensitizer is injected into the patient,it will be soon enriched in tumor tissue while the tumor tissue is irradiated with light of a specific wavelength.It can produ…
Three welded beam-column connection substructures of steel frame with two kinds of weld access holes( fan-shaped and enlarged weld access hole) were designed based on the Chinese seismic code and relevant references. The impact tests using drop-hammer were carried out to simulate the dynamic behavior of structural pro…
To research the influence of different heterogeneous parameters on bursting liability of coal,the uniaxial compressing tests of heterogeneous coal based on Weibull distribution with different elastic modulus and bonding strength were simulated by using particle flow code( PFC). The accumulation and release of energy w…
The need for bitumen modification allowing lower asphalt production temperatures is a direct result of economic and environmental issues. Compared with the traditional Hot Mix Asphalt (HMA) technology, foamed bitumen used in the Warm and Half Warm Mix Asphalt (WMA, HWMA) processes provides an approximately 30–40 °C re…
Reinforced concrete beams are normally designed as under reinforced to provide ductile behavior such as the tensile moment of resistance.In coastal environment reinforcement corrosion is an obvious cause of deterioration of concrete structure, which affects the durability and service of reinforced concrete structure.S…
The present article considers an experimental study of tribo-corrosion behavior of electroless Ni-P coatings in alkaline environment sliding against alumina. The study of wear and friction behaviour is carried out using different load and sliding speed with the help of a pin-on-disk tribometer. The wear rate increases…
To apply a transformation-induced plasticity (TRIP)-aided steel consisting of bainitic ferrite structure matrix and metastable retained austenite of 10 vol% (TBF steel) to some precision gears, the effects of fine particle peening on the Vickers hardness and residual stress in a surface layer of the TBF steel were inv…
numerous advantages include improved efficacy ,reduced toxicity and improved patients compliance and convinence.Many advanced drug delivery systems are being introduced for the intrapocket delivery of drugs at the diseased site.Non-degradable and degradable systems have been developed for the delivery of antimicrobial…
