this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...

       Biosurfactants are surface-active compounds produced by microorganisms. In this study, we collected 60 inguinal area and ear canal samples from cows, sheep, and goats (each, 10 animals) and screened for biosurfactant-producing bacteria. We also determined the genera of culturing strains. Fifty six hemolytic bacterial strains (27, 22 and 7, from cows, sheep and goats, respectively) were i...

The objective of this study was to determine if neonatal piglets would interact with environmental enrichment ropes, drawing them away from the sow. A total 84 9 sows were housed in farrowing stalls. Litters provided ropes hung at piglet eye level above a heat mat on Day 2 5 after farrowing. assigned one three rope treatments: 1) sunflower oil (OIL), 2) semiochemical (SC) and 3) milky cheese (M...

Oil seed rape (Brassica napus L.) cultivars, donors of quality (SC) and self-incompatible (SI) lines have been analysed using identification of S-locus. In several Brassica napus cultivars one S-locus SLG gene was detected as dominant and the second S-locus as recessive. Amplification class II SLG gene screened recessive gene in all analysed samples (SC and SI). The DNA fragment of recessive ge...

OBJECTIVES Repaglinide (RG) is an antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus. It has a good safety and efficacy profile in diabetic patients with complications in renal impairment and is an appropriate treatment choice, even for individuals with more severe degrees of renal malfunctions. The aim of the present study was to examine the protective ef...

Molecular dynamics simulations of bulk copper, gold pure metals and their ordered intermetallics alloys of Cu3Au(L12) and CuAu3(L12) have been carried out between above 0 K and below the their melting points of the materials for predicting their temperature-dependent thermophysical properties. The effects of temperature and concentration on the physical properties such as enthalpy, volume, heat...

Benjamin Franklin, mostly known for his participation in writing The Declaration of Independence and work on electricity, was also one of the first scientists to seek to understand the properties of oil monolayers on water surfaces. During one of his many voyages across the Atlantic Ocean, Franklin observed that oil had a calming effect on waves when poured into rough ocean waters. Though at fi...

With the rapid development of science and technology, high-dimensional data have been widely used in various fields. Due to complex characteristics data, it is usually distributed union several low-dimensional subspaces. In past decades, subspace clustering (SC) methods studied as they can restore underlying perform fast with help self-expressiveness property. The SC aim construct an affinity m...

BACKGROUND The search for more eco-friendly acaricides has prompted testing of medicinal plants from botanical sources. OBJECTIVE To evaluate the eradication of house dust mites (HDM), Dermatophagoides pteronyssinus, by direct contact using the essential clove oil (Eugenia caryophyllus). METHODS A pilot study was initiated to determine the killing power of clove oil. Synthetic fibers were i...

We study the destabilization mechanism of thin liquid sheets expanding in air and show that dilute oil-in-water emulsion-based sheets disintegrate through the nucleation and growth of holes that perforate the sheet. The velocity and thickness fields of the sheet outside the holes are not perturbed by holes, and hole opening follows the Taylor-Culick law. We find that a prehole, which widens and...
