PURPOSE To evaluate surface properties of various intraocular lenses (IOLs), including a newly fabricated heparin-surface-modified (HSM) silicone IOL, with special reference to their efficiency in reducing potential silicone oil adherence to the IOL optics. SETTING Center for Research on Ocular Therapeutics and Biodevices, Department of Ophthalmology, Storm Eye Institute, Medical University o...

the economy's dependence on oil revenues and derivatives of these products make the country's economy heavily influenced by the volatility and instability of the pricing of these products. therefore, it seems necessary to develop non-oil exports. this paper examines the causality relation and the effect of foreign direct investment, economic openness and real exchange rate on non-oil ...

introduction:this study examined the effects of administration of subcutaneous β-estradiol on ptsd-like symptoms (the enhanced conditioned fear response, cfr) that induced by a single-prolonged stress (sps) and shock in rats. adult male wistar rats were exposed to sps procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. then the rats were placed in fear conditioning syste...

Alkaline/surfactant/polymer (ASP) flooding has been extensively applied to enhancing oil recovery. As an oil displacement agent, pe1troleum sulfonate (PS) is widely used in ASP pilot experiments. It is very important to find a petroleum sulfonate with a high interfacial activity and low adsorption loss. Anionic surfactant petroleum sulfonate is synthesized in a single-tube film sulfonation reac...

Multiparameter flow cytometry is commonly used for the analysis of cells and droplet microreactors. However, their cost and complexity limits its applications in point-of-care systems. This paper demonstrates a high speed frequency multiplexed electronic detector for multicolor flow cytometry. The system can detect multiple fluorophores on a single PMT, rather than one per fluorophore. The dete...

African oil palm has the highest productivity amongst cultivated oleaginous crops. Species can constitute a single crop capable to fulfill the growing global demand for vegetable oils, which is estimated to reach 240 million tons by 2050. Two types of vegetable oil are extracted from the palm fruit on commercial scale. The crude palm oil and kernel palm oil have different fatty acid profiles, w...

Bacteriol. 91:975-983. 1966.-Antituberculosis vaccines were prepared in one of three manners: lyophilized BCG suspended in light mineral oil was disrupted in a Sorvall pressure cell and the "oil disrupti...

salvia is one of the largest genera of  lamiaceae family. several species of this genus are perfumed and wealthy in essential oils. some of them are used in industry, pharmacy and aromatherapy. they have shown different biological effects such as antibacterial and antioxidant activity. for the present study, salvia verticillata l. was collected from shahrestanak, mazandaran, iran. hydrodistille...

a r t i c l e i n f o Keywords: Avoidance Bakken Grassland birds Oil development Piecewise regression Sprague's pipit Oil development in the Bakken shale region has increased rapidly as a result of new technologies and strong demand for fossil fuel. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examine...

The economy of the state of Tabasco is based on oil extraction. However, this imposes major effects to the environment and communities. Examples are the Polycyclic Aromatic Hydrocarbons (PAHs) that may be found in the soil, water and sediment of the region. Their volatility makes them available to living beings and results in genotoxic activity. The purpose of this study was to quantify the lev...
