Injection of optimized chemistry water in enhanced oil recovery (EOR) has gained much interest in the past few years. Crude oil-water interfaces can have a viscoelastic character affected by the adsorption of amphiphilic molecules. The brine concentration as well as surfactants may strongly affect the fluid-fluid interfacial viscoelasticity. In this work we investigate interfacial viscoelastici...

in the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

Musk, A. W., and Gandevia, B. (1976). British Journal of Industrial Medicine, 33, 158-165. Loss of pulmonary elastic recoil in workers formerly exposed to proteolytic enzyme (alcalase) in the detergent industry. Sixty-seven workers in the detergent industry whose exposure to proteolytic enzyme ceased in 1969 have been examined clinically and functionally. By comparison with 42 lightly and moder...

– We consider a simple model of a random heteropolymer chain that is known to undergo the freezing transition. We investigate the change in the elastic properties of the chain upon freezing. The elastic constants are evaluated and it is shown that they acquire a non-trivial contribution in the frozen phase. The goal of this letter is to investigate the elasticity of a random heteropolymer chain...

the effect of different mozzarella cheese manufacturing methods, i.e. direct acidification (da), starter culture (sc) and their combination method (cm) on physicochemical, yield, texture, color and sensory properties of the product were compared. chemical analyses of samples revealed that the sc cheese had higher fat, moisture, ash, titratable acidity, actual and adjusted yields and fat recover...

Strong seasonal variations of horizontal and vertical positions are observed on GPS times series from stations located in Nepal, India and Tibet (China). We demonstrate that this geodetic deformation is induced by seasonal variations of continental water storage driven by the Monsoon. For this purpose, we use satellite data from the Gravity Recovery and Climate Experiment (GRACE) to determine t...

In order to improve the viscoelasticity of bitumen, several modifiers were compounded with it, including SBS, reclaimed rubber powder, tackifier, plasticizer, and oil stabilizer, produce High-viscosity High-elastic Modified Bitumen (HVE-MB). The various physical rheological properties bitumen evaluated using a number factors, such as dynamic viscosity at 60 °C, elastic recovery, penetration, so...

The human ankle plantar-flexors, the soleus and gastrocnemius, utilize tendon elastic strain energy to reduce muscle fiber work and optimize contractile conditions during running. However, studies to date have considered only slow to moderate running speeds up to 5 m s(-1). Little is known about how the human ankle plantar-flexors utilize tendon elastic strain energy as running speed is advance...

reservoir characterization plays an important role in different parts of an industrial project. the results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. delineating hydrocarbon bearing zones within a reservoir is the main objective of any seismic reservoir characterization...

Abstract Consumer choice and behavior are changing focusing on comfortable clothing along with fitting. Elastic yarn or fabric is necessary to achieve this comfortableness. By making elastic using material in production, cloths produced proper stretchability recovery. For that, core-spun was used, but due a lack of recovery performance, dual has been developed. Different elastane ratios, linear...
