Under the effects of electric field and chemical reaction, a mathematical model has been developed to study the dispersion of aerosols in a couple stress fluid flowing through a channel which is analytically solved using Taylor disper¬sion model. The solutions for velocity, concentration distribution and dispersion coefficient are numerically computed and the results are represented graphically...

Background and aim: Using appropriate methods for the assessment of fetal health including non-stress test during high-risk pregnancies due to possible placental insufficiency is of paramount importance. Due to complexity in medical decisions, using information systems is being increased to support complex medical decisions. We conducted this study to measure the diagnostic value of non-stress ...

The rheological properties of acid hydrolyzed corn stover at high solids concentration (20-35 wt.%) were investigated using torque rheometry. These materials are yield stress fluids whose rheological properties can be well represented by the Bingham model. Yield stresses increase with increasing solids concentration and decrease with increasing hydrolysis reaction temperature, acid concentratio...

Life is surrounded by stress! More correctly, cells are constantly exposed to different stress stimuli. These may be acute or chronic in nature and may take the form of both chemical and physical stimuli. Changes in environment, injury, or disease may place an organism under stress. Evolution has provided many different means by which organisms can adapt to changes in stress, and the stress res...

Mechanical stress can drive chemical reactions and is unique in that the reaction product can depend on both the magnitude and the direction of the applied force. Indeed, this directionality can drive chemical reactions impossible through conventional means. However, unlike heat- or pressure-driven reactions, mechanical stress is rarely applied isometrically, obscuring how mechanical inputs rel...

springs are the  mechanical parts which have many application in industries. static and dynamic forces cause relaxation in these parts so that they lose some of their free length and reaction force. springs constant are very important in airplane and vailway industry since constant and variable forces are applied to them in period time, therefore it is necessary to avoid decreasing in spring co...

When a person experiences a traumatic event, s/he may have a strong emotional reaction. This reaction may disrupt the person's ability to function at the scene of the incident or later, and may range from a normal stress response to the symptoms indicative of Post Traumatic Stress Disorder (PTSD). Psychological debriefing is an immediate intervention used following a traumatic experience that p...

Anecdotes on the ability of individuals to continue to function under stressful conditions despite injuries causing excruciating pain suggest that acute stress may induce analgesia. However, studies exploring the effect of acute experimental stress on pain perception show inconsistent results, possibly due to methodological differences. Our aim was to systematically study the effect of acute st...

BACKGROUND Bone stress reaction is prevalent among cricket fast bowlers. Few studies have addressed the sensitivity and specificity of imaging for diagnosis, and follow up assessment has been poorly investigated. OBJECTIVE To determine whether there was an association between back pain and bone stress reaction as measured by computed tomography (CT) scan in young cricket fast bowlers. METHO...
