in this work, the potential of auto-ignition of heavy oil during in-situ combustion (isc) process was studied. kinetic studies were carried out using thermo gravimetric analyzer (tga), differential scanning calorimetry (dsc) and accelerating rate calorimetric (arc) techniques. effects of oxygen partial pressure, reservoir pressure and clay on auto ignition condition were investigated on a numbe...

this study aims at exploring an effective route in the in situ graft polymerization of aniline from fe3o4 nanoparticles. to this goal, fe3o4 magnetic nanoparticles were prepared by coprecipitation method using ammonia solution as the precipitating agent, and were characterized by fourier transform infrared (ft-ir) spectroscopy, x-ray diffraction (xrd) and transmission electron microscopy (tem)....

purpose : to describe a case of successful laser in situ keratomileusis (lasik) retreatment over a previous lasik surgery after 11 years case report : the patient had his first lasik for the correction of -2.25 -1.75×90° and -2.25 -1.00×90° in the right and left eye, respectively. eleven years later, the refraction in the right eye was plano -3.25×80° and he was scheduled for an enhancement pro...

purpose: to report occurrence, management, and outcome of late-onset traumatic dislocation of laser in situ keratomileusis (lasik) flaps case report: we report a patient with late-onset lasik corneal flap dislocation after blunt ocular trauma occurring four years after surgery. an ultrasound biomicroscopy (ubm) was performed to view the status of flap and determination of flap thickness. result...

In 2008, molecular methods continue to be mainstream in environmental engineering research. Fingerprinting techniques such as denaturing gradient gel electrophoresis (DGGE) and terminal restriction fragment length polymorphism (T-RFLP) analysis continue to be popular tools to track differences in microbial community composition over time and space. Fluorescent in situ hybridization (FISH) of wh...

3D CuInS2/TiO2 nanocomposite solar cell performance is strongly influenced by several structural factors, including cell thickness, buffer layer thickness, and the morphology of the TiO2 nanoparticulate matrix. To delineate the effect of these structural factors on photovoltaic performance, a series of parametric studies are performed where a single structural parameter is varied (TiO2 nanopart...

The bibliometric data were extracted from the Scopus database to investigate conceptual framework of ocular nanoemulsion and/or in-situ gel drug delivery system using “ocular” AND “nanoemulsion” OR “in-situ gel” keywords. evaluated with RStudio and VOSviewer program. results reveal that publication trends tend increase continually. India is most impactful country, constructive institution Depar...

The human nose has the potential to be an alternative route for the systemic delivery of a wide range of therapeutic agents. The richly supplied vascular nature of the nasal mucosa and its high drug permeation makes it a potential route for the administration of many drugs including proteins, peptides and vaccines. Nasal route is most suitable for those drugs which cannot be administered orally...

Recent work shows that nanoparticulate and amorphous molybdenum and tungsten sulfide materials are active catalysts for hydrogen evolution in aqueous solution. These materials hold promise for applications in clean hydrogen production technologies. In this perspective, the syntheses, structures and catalytic activities of nanoparticulate MoS2 and WS2, incomplete cubane-type [Mo3S4] 4+ and amorp...
