degradation of dry matter (dm) and nitrogen (n) in fresh or frozen-thawed alfalfa and ryegrass was studied by using in situ technique. the forages were labeled with 15n during growth in a glasshouse, harvested at similar growth phase, and fresh (f) or frozen-thawed (ft) samples were incubated in the rumen of 3 sheep. there was no difference (p>0.05) between forage type (s) for the immediately s...

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...
