The transition to turbulence in pipe and plane Couette flow differs from the better understood situation of Taylor-Couette or Rayleigh-Bénard flow in that the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers. Moreover, even when turbulent flow is established, it can spontaneously return to laminar flow. These observations are compatible with the formation o...

By the late 1800s, both phenacetin and acetanilide were used as analgesics and antipyretics, but their acceptance was limited by significant side effects including methemoglobinemia. N-acetyl-p-aminophenol (APAP) is a major metabolite of phenacetin and acetanilide, and is responsible for, both analgesia and antipyresis. APAP was synthesized in 1878 and has a low risk of causing methemoglobinemi...

introduction: gluten is a protein found in grains.  research has shown that the gluten that is in grains of wheat, barley, rye, and oats (to a lesser degree) is toxic to many individuals.  while gluten is essential for the make-up of these 4 grains, our bodies do not need it. is it healthful?  the protein in today’s wheat is poorly digested and can be harmful.  an estimated 95% of prepared food...

ABSTRACT In recent times, green technologies have gained space and interest in many industrial sectors. Examples of this are enzymes, which can be obtained by solid-state fermentation using microorganisms agro-industrial residues as substrates. context, study aimed to verify the production hydrolases leading Arthrobacter polychromogenes Streptomyces violaceoruber strains producers influence moi...

Diverticula are thought to arise from defects in the muscularis layer of the intestines (Fig. 35.1) and are related to abnormalities in muscle tone and increased intraluminal pressure; saclike protrusions eventually form at points of weakness. If stool is caught in these sacs, it becomes inspissated and hardened and causes abrasions of the mucosa that lead to inflammation, although the same end...

17beta-Estradiol (17beta-E(2)) is known to exert neuroprotective activity against beta-amyloid, but its exact target and mechanism of action in this effect have not been elucidated. The involvement of astroglia in neuroprotection of 17beta-E(2) against the beta-amyloid fragment [betaAP((25-35))] has been evaluated using an experimental paradigm in which medium conditioned from rat astroglia pre...

The influence of temperature on the development and embryonation of Ascaris suum eggs was studied using coarse sand medium in an environmental chamber with 50% humidity. The time required for development and embryonation of eggs was examined under 3 different temperature conditions, 5°C, 25°C, and 35°C. A. suum eggs did not develop over 1 month at the temperature of 5°C. However, other temperat...
