Aluminum anodes have been widely used in the cathodic protection of marine structures. However there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. Addition of alloying elements such as Zn and In not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra ...

Delegates from the following countries attended the workshop: Ghana, Nigeria, Uganda, Kenya, Tanzania, Sudan, Malawi, Zimbabwe, Botswana, Namibia, SA, Zambia, Ethiopia, Rwanda, Mozam...

High-speed counter-current chromatography (HSCCC) is a versatile technique in preparative separation and purification of pure compounds from complex matrices. As a preparative chromatography, there is a need to maximize the column production. Based on the plate theory of Van Deemter, the effect of the sample load on the separation was investigated in a preparative HSCCC with a 1000 ml column ca...

DOI:10.1111/j.1758-5872.2012.00210.x Abstract The ethical problem of the need to conduct research on the very conditions that impair the ability to consent to such research is widely acknowledged. People with cognitive impairment and mental illness have an equitable right to research being conducted in areas relevant to their treatment and care, and should be given an equitable opportunity to p...

Different equivalent circuits are presented to describe the capacity current, Ic, of potential-clamped Ranvier nodes. The corresponding transfer functions are discussed in examining the influence of the involved parameters on size and time course of Ic. The following results were obtained: i. The duration and the amplitude of Ic increased with increasing membrane capacity. ii. The amplitude of ...

Despite the challenges of geographic isolation, a small population and limited financial resources, the Republic of Palau has been able to significantly improve its ability to address disasters through establishing an emergency health program funded by US Federal Grants. The ability to prevent and respond to ordinary emergencies and disasters has been bolstered by creating electronic Public Hea...
