background and objectives: sodium dodecyl sulfate (sds) is one of the main surfactant components in detergents and cosmetics, used in high amounts as a detergent in products such as shampoos, car wash soap and toothpaste. therefore, its bioremediation by suitable microorganisms is important. alkylsulfatase is an enzyme that hydrolyses sulfate -ester bonds to give inorganic sulfate and alcohol. ...

Livestock in West Africa is an example of regional value chain development. It essentially based on the trade livestock between production areas and consumption centers. The important economic activity pastoral agro-pastoral communities as it their source income. these regions takes place at several sites, best known which are markets. Two different types market investigated this study. Self-ma...

Title of Dissertation: Forming Binary Near-Earth Asteroids From Tidal Disruptions Kevin J. Walsh, Doctor of Philosophy, 2006 Dissertation directed by: Professor Derek C. Richardson Department of Astronomy We present simulations and observations as part of a model of the binary near-Earth asteroid population. The study of binary asteroid formation includes a series of simulations of near-Earth a...

During official shellfish control for the presence of marine biotoxins in Greece in year 2012, a series of unexplained positive mouse bioassays (MBA) for lipophilic toxins with nervous symptomatology prior to mice death was observed in mussels from Vistonikos Bay-Lagos, Rodopi. This atypical toxicity coincided with (a) absence or low levels of regulated and some non-regulated toxins in mussels ...

Cost-effective expansion of human mesenchymal stem/stromal cells (hMSCs) remains a key challenge for their widespread clinical deployment. Fibroblast growth factor-2 (FGF-2) is a key hMSC mitogen often supplemented to increase hMSC growth rates. However, hMSCs also produce endogenous FGF-2, which critically interacts with cell surface heparan sulfate (HS). We assessed the interplay of FGF-2 wit...

Despite the availability of elaborate methods for defining data and business processes, huge amounts of time and effort are wasted on system projects that produce disappointing results. An important contributing factor is the significant difficulty business and IT professionals experience when they try to describe, evaluate, and/or analyze systems in organizations even at a cursory level. Betwe...

This lecture is a short review on the role entropy plays in those classical dissipative systems whose equations of motion may be expressed via a Leibniz Bracket Algebra (LBA). This means that the time derivative of any physical observable f of the system is calculated by putting this f in a “bracket” together with a “special observable” F, referred to as a Leibniz generator of the dynamics. Whi...
