Dynamic capabilities enable firms to create new products and processes and respond to changing market conditions. This empirical investigation of dynamic R&D capabilities deals with the role of complementary know-how and other assets in the context of changing conditions in the U.S. petroleum industry during the 1970s and early 1980s. The analysis suggests that, in response to rising oil prices...

The remarkable ability of polymeric additives to reduce the level of frictional drag significantly in turbulent flow, even under extremely low dilutions, is known as turbulent drag-reduction behavior. Several bio-polymers have been assessed as promising drag-reducing agents for the potential replacement of high molecular weight synthetic polymers to improve safety and ameliorate environmental c...

Since the synthesis of 2,4-D, a number of other synthetic auxins have become commercially available. Although these products are referred to as growth regulators or phytohormones (previously known as plant hormones), they really represent only one group of growth regulators, the auxins. Auxins can be divided into six major groups; indole acids, naphthalene acids, phenoxy carboxylic acids, benzo...

Currently, research on the bambangan-fruit seed has become interesting because of its potential application as a cocoa butter alternative. This work aimed to determine changes in quality extracted bambangan-seed fat (BSF) obtained using hexane, petroleum ether, and ethanol. The extraction solvents affected total content (TFC), physicochemical properties, fatty-acid profile, triacylglycerol comp...

For the first time, polar organic compounds in extracted bitumen from Lower Triassic Montney Formation have been analyzed. This stratigraphic unit is one of most prolific low-permeability reservoirs Western Canada. However, its geochemical characterization a challenge due to low biomarker concentration liquids and frequent mixing gas/condensate hydrocarbons. Since typical biomarkers were not av...

The physicochemical properties and fatty acid composition of Attalea dubia (Mart.) Burret (indaiá) seed oil were investigated. The oil was extracted in a soxhlet apparatus using petroleum ether and evaluated for iodine, acid, peroxide, ester, and saponification values. The oil was also analyzed using infrared and nuclear magnetic resonance spectroscopy. The fatty acid profile of the oil was de...

Fatty acid-derived biofuels can be a better solution than bioethanol to replace petroleum fuel, since they have similar energy content and combustion properties as current transportation fuels. The environmentally friendly microbial fermentation process has been used to synthesize advanced biofuels from renewable feedstock. Due to their robustness as well as the high tolerance to fermentation i...

By-products obtained from winemaking processes still contain large amounts of phenolic compounds, especially phenolic acids, flavanols, flavonols, stilbenes, and flavonoids. Enzymatic hydrolysis was used for determination and characterization of phenolic acids, flavanols, flavonols, and stilbenes. Characterization of the flavonoids was achieved using acid hydrolysis with 0.1% hydrochloric acid....

Three strains of Bacillus anthracis and seven strains of Bacillus cereus were grown on complex medium and on synthetic medium. Gas chromatographic analysis of whole-cell fatty acids of strains grown on complex medium gave nearly identical fatty acid patterns. Fatty acid patterns of strains grown on synthetic medium showed a high content of branched-chain fatty acids. Significant differences bet...
