Sperm of the following Neotropical Characiformes fish species were tested for cold storage: Brycon lundii, Piaractus mesopotamicus, Leporinus elongatus, Leporinus friderici, Prochilodus lineatus and Prochilodus marggravii. Each sperm sample was split into two aliquots. The first was placed into a plastic bag with air or oxygen and the second, in a plastic tube with air. The samples were maintai...

The multiple impulse input is introduced as a substitute of the long-duration earthquake ground motion, mostly expressed in terms of harmonic waves, and a closed-form solution is derived of the elastic–plastic response of a single-degree-of-freedom structure under the “critical multiple impulse input.” Since only the free vibration appears under such multiple impulse input, the energy approach ...

accumulative roll bonding (arb) was used to fabricate the cu-zn multilayer and cu-zn solid solution. a lamellar structure with the hardness of about 130 vhn was formed after eight arb cycles. following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 vhn was produced. the dominant wear mechanism in the arb processed multilayer was found to ...

Vancomycin is administered orally for the treatment of pseudomembranous colitis induced by Clostridium difficile. Vancomycin is marketed for this purpose by ViroPharma as VANCOCIN in 125-mg and 250-mg capsules. The need for other dose form options for those patients who cannot take capsules has led compounding pharmacies to seek other alternatives, namely oral solutions and suspensions. Additio...

BACKGROUND Sodium hypochlorite (bleach) solutions are widely used as irrigants in endodontics. Their tendency to deteriorate is worsened by environmental influences which could cause loss of available chlorine content. METHODS This study measured the loss of available chlorine concentration in a range of sodium hypochlorite solutions under conditions which mimic clinical usage and storage. Do...

The plastic hardener methyl ethyl ketone peroxide is unstable peroxide that releases free oxygen radicals. Ingestion of this compound induces widespread liver necrosis, severe metabolic acidosis, corrosive esophagitis and gastritis, that is often fatal. A 49-year-old man unintentionally ingested approximately 100 mL (55%) of this compound in solution, which was purchased as plastic hardener. De...

Non-Symmetrical Plastic Collapse Modes of a Symmetrically Loaded Circular Cylinder. P18stic collapse modes of a thick-walled homogeneous cylinder under circularly-symmetrical loading (internal and external normal pressures) are analyzed. Ideal plasticity, I-IUBEIt-~ISES-HENC]~Y yield condition, incompressibility and plane strain conditions are assumed. The possibility of existence of non-syrm~e...

In 1956, Truelove introduced the successful topical corticosteroid treatment for ulcerative colitis, using a modified blood transfusion set. To simplify the technique Matts (1960) introduced disposable plastic enema bags. We have extensively used both these methods. The modified blood transfusion set is better suited to inpatient than to out-patient treatment. The disposable bags, while simpler...

Eco -friendly architectural principles are being incorporated into more buildings every day in the world but they are still out of reach of many people due to lack of knowledge and awareness. Nevertheless, many traditional societies learned to build collaborating with nature, basing their buildings on an intuitive knowledge of the environment and climate, constructing buildings at a very low co...

It is a highly nonlinear problem of 3-D elastoplastic contact with friction. To obtain the key information about the real size, displacement and traction in contact zone, the elements in contact and plastic zone should be subdivided. However, the increase of degrees of freedom is limited by the problem-solving scale when traditional BEM is used, for a larger memory size is required and the solu...
