This paper presents a design of a compact heavy duty robot for automated CNC loading and unloading process control. The robot can load up to 165kg and complete motion control and positioning with high accuracy. The design has been carried out in several modules including mechanical parts, electronic parts, control system, and programming. It brings several innovations such as high loading capac...

Methionine loading seems to be accompanied by increased oxidative stress and damage. However, it is not known how this oxidative stress is generated. We performed the present crossover study to further elucidate the effects of methionine loading on oxidative stress in the blood of healthy volunteers, and to examine possible preventative effects of N -acetylcysteine (NAC) administration. A total...

In recent years, use of biodegradable polymers based nanoparticles has received highinterest in the development of vaccines delivery vehicles. The aim of study was to preparechitosan nanoparticles (CS NPs) for loading Echis carinatus (EC) venom and evaluate theirpotential as an adjuvant and antigen delivery system on a pilot scale. CS NPs were preparedusing ionic gelation method, and their char...

in this work we synthesized of mesoporous silica nanoparticles and functionalized with 3-aminopropyltriethoxysilane to improve the loading and release of ibuprofen bonded to 3-aminopropyltriethoxysilane. sample were characterized by fourier transform infrared spectroscopy, scanning electron microscopy , x-ray diffraction, and ultraviolet-visible. the fourier transform infrared spectroscopy resu...

the chitosan nanoparticles used widely as a drug delivery systems recently. in the present study the echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. the nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. the particles were spherical in shape and th...

in this study two identical anaerobic completely mixed fluidized bed reactors with gac and sand media were employed for cod & phenol removal. at loading rate of 1.6 g phenol l-1d-1, the efficiency of phenol removal in gac & sand reactors were 97.7% & 74%, respectively. at high loading rate of phenol (6.09 g phenol i: 1d1) the efficiency of phenol removal in gac reactor was better than 95%. in g...

The engineering of hollow nanostructures is a promising approach to addressing instabilities in silicon-based electrodes for lithium-ion batteries. Previous studies showed that a SiOx coating on silicon nanotubes (SiNTs) could function as a constraining layer and enhance capacity retention in electrodes with low mass loading, but we show here that similarly produced electrodes having negligible...

Transgenic tobacco (Nicotiana tabacum) plants expressing green fluorescent protein (GFP) from the AtSUC2 promoter were used to study the function of different vein classes in developing leaves. In sink leaves, unloading capacity occurred acropetally, with the class I (midrib) and class II veins becoming functional in phloem unloading before the maturation of the class III veinal network. In con...

Polypropylenimine (PPI) dendrimers have been widely used as effective delivery vehicles for drugs and nucleic acids during the past decade. However, biomedical applications of PPI dendrimers were limited because of their serious cytotoxicity and low drug loading capacity. In the present study, acetylated PPI dendrimers with different degrees of acetylation ranging from 14.2% to 94.3% were synth...

The use of static load testing in optimising design and providing verification of suitability and constructability continues to be unsurpassed in the foundation industry. The utilisation of top load reaction testing appears to be that with which most European engineers are familiar, but a variation on this, which has become just as conventional in some parts of the world, is the use of bi-direc...
