An experimental study has been made of the hydrodynamics of a stage mixer-settler to obtain appropriate design information. In this paper several tests were done according to full factorial design of experiments with high reliability, since each test recurs seven times and the results of  them are very close to each other(P=1bar and T=25 °C). Sauter diameter in each test is determined with ...

Drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. In this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. A video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...

Transitional justice has become the dominant international framework for redressing mass harm and historical injustices. However, transitional justice is commonly premised on the notion of a recent point of rupture or change from violence and oppression to a ‘new dawn’, and has therefore been less attuned to accommodating the long-term effects of colonialism. Accordingly, the historical experie...

elaeagnus angustifolia has many potential applications in drugs, detergents, perfumes, herbal teas and show various biological and pharmacological activities, such as anti-inflammatory, antipyretic and other effective treatment of disease. gallic acid (ga) and its derivative methyl gallate (mg) are well studied plant phenolics. they have exhibited anticancer effects in several cancer cell lines...

In this article a dynamic model of a continuous working UASB reactor is described. It results from the integration of the fluid flow pattern in the reactor, the kinetic behavior of the bacteria (where inhibition and limitation were taken into account), and the mass transport phenomena between different compartments and different phases. The mathematical equations underlying the model and descri...

A non-malleable extractor is a seeded extractor with a very strong guarantee – the output of a non-malleable extractor obtained using a typical seed is close to uniform even conditioned on the output obtained using any other seed. The first contribution of this paper consists of two new and improved constructions of non-malleable extractors: We construct a non-malleable extractor with seed-leng...
