background: the diagnosis of ocular toxoplasmosis is mainly based on clinical features. however, ocular fluid testing by pcr may be very helpful for approval or rejection of this etiology. in this study, we utilized a nested-pcr technique, targeting the b1 partial sequence to analyze the aqueous and vitreous samples for evaluating the presence of the toxoplasma dna. methods: fifty aqueous or vi...

Paul C. Rizzo Associates, Inc. (RIZZO) has developed efficient computational tools to evaluate the liquefaction potential of earth embankment dams located within high risk seismic regions. Two relevant case histories are the Saluda Dam and the Santee Cooper East Dam Extension, both structures susceptible to liquefaction, and located in South Carolina. Saluda Dam presents liquefaction risks with...

The marine industry has been striving to seek for proper strategies curb air emissions from global shipping activities. To support the transition sustainable shipping, this paper was proposed evaluate holistic environmental benefits of LNG partial re-liquefaction system applied carriers by comparing among five different combination/configuration systems. theory life cycle assessment employed wi...

In this study, it is attempted to analyze sensitivity and reliability in order to evaluate the liquefaction potential in soil layers in Tabriz. 62 boreholes that had possible conditions for liquefaction were selected. Seismic mapping was simulated using finite fault method and then the effect of soil layers on PGA was estimated. In continue, the liquefaction potential index was estimated and th...

Macular hole (MA) is a significant cause of visual acuity (VA) loss in patients over 50 years in our environment. The traction by the vitreous, particularly the posterior hyaloids, on the retina surface plays a leading role in the etiopathogeny of MA. The collagen fibers that comprise the posterior vitreous are firmly joined to the macula and connecting to the internal limiting membrane by mean...

earthquakes could have catastrophic impacts on tunnels and buried structures. liquefaction phenomenon is one of the most destructive effects of earthquakes. liquefaction results in decreasing effective stress and this consequently leads to decreases in shear strength of the soil. as a result, large deformation in both soil and buried structure occurs. moreover, liquefaction causes soil boiling,...

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...

Comparing to the conventional bath heating, the effects of liquefaction parameters on the degree of liquefaction of wood in polyhydric alcohols by using microwave as an energy source were evaluated. Polyurethane foams were successfully prepared from the liquefied biomass-based polyols. The effects of heating methods (conventional bath heating and microwave) and liquefaction reaction time on the...

A parametric study approach evaluating drained/undrained behavior of sand has been developed as a simple/quick hypo-elastic model capable of being used in engineering applications. The volumetric interaction of sand grains behavior against pore water pressure induces the tendency of soil mass volume change to contract/dilate due to variation of effective mean stress on solid grain, pore water p...

Purpose: We report a case of macular, serous retinal detachment associated with hypotony in patient pachychoroid disease developing after Ahmed valve implantation.Case summary: A 77-year-old male visited our clinic uncontrolled intraocular pressure (IOP; 32 mmHg) his left eye despite maximal tolerable medical therapy. prolapsed vitreous filled the anterior chamber. Swept-source optical coherenc...
