A comparative study on the biochemical parameters in hydatid cyst fluids of sheep, goats, camels, cattle and human cystic forms of Echinococcus granulosus has been made in Libya. Quantitative variations in the levels of sodium, potassium, calcium, cholesterol, glucose, urea, creatinine and gamma glutamyl transpeptidase (gamma GT) were found in the cystic fluids of different host origins althoug...

Magnetorheo]ogical (MR) fluids are colloidal suspensions of pammagnetic particles in a non-magnetic fluid. These fluids, along with their electrical analogues, electrorheologica] (ER) fluids, have been proposed as controllable fluids, for use in electromechanical devices such as dampers, clutches and brakes. [1] When exposed to an external magnetic field, the particles acquire dipole moments ag...

Synovial fluids from patients with osteoarthritis contain a chemotactic inhibitor that acts by antagonizing the complement-derived chemotactic anaphylotoxin, C5a. The activity of this inhibitor in synovial fluids from patients with several forms of inflammatory arthritis (rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, and gout) were comparable to the activity presen...

There are essentially three main categories of drilling fluids: oil based fluids (OBF’s), synthetic based fluids (SBF’s) and water based fluids (WBF’s). OBF’s have been traditionally been used for their high performance drilling characteristics but tend to have a poor environmental performance in terms of their ecotoxicity and their tendency to persist in cuttings piles on the seafloor. More re...

Potential flows of incompressible fluids admit a pressure (Bernoulli) equation when the divergence of the stress is a gradient as in inviscid fluids, viscous fluids, linear viscoelastic fluids and second-order fluids. We show that the equation balancing drag and acceleration is the same for all these fluids independent of the viscosity or any viscoelastic parameter and that the drag is zero in ...

Parallel to the developments in the technology, a large number of cutting fluids were developed and used. Cutting fluids should contain suitable additions depending on the workpiece to be machined and the machining parameters. Their lubrication effects should be considered at the lower cutting speeds while their cooling effects should be considered at higher cutting speeds. In this study, descr...

physiologists have shown that increased fluids improve skeletal muscle performance in prolonged exercise.typical orders provide for 125 ml of intravenous fluids per hour in patients taking limited oral fluids during labor. our purpose in this study was to determine whether increased intravenous fluids affect the progress of labor. in a prospective randomized institutional clinical trial, one-hu...

OBJECTIVE To determine whether the use of hypotonic vs isotonic maintenance fluids confers an increased risk of hyponatremia in hospitalized children. STUDY DESIGN A search of MEDLINE (1946 to January 2013), the Cochrane Central Registry (1991 to December 2012), Cumulative Index for Nursing and Allied Health Literature (1990 to December 2012), and Pediatric Academic Societies (2000-2012) abst...

BACKGROUND/OBJECTIVE We evaluated the sensitivity of PCR on oral fluids in detecting influenza virus in vaccinated and non-vaccinated pigs. METHODS Three-week-old influenza-free pigs were divided into three groups: (i) control, non-vaccinated, (ii) vaccinated with a commercial, heterologous vaccine, and (iii) vaccinated with an experimental, homologous vaccine. After vaccination, an influenza...

Mean squared displacements and velocity auto correlation functions are calculated using molecular dynamics for hard spheres under a range of conditions (i) for the equilibrium fluid below freezing; (ii) for the metastable fluid above freezing; and (iii) for the hard sphere crystal, both in the metastable region between freezing and melting, and in the stable region above melting. In addition, s...
