Comparisons of Oil Shale Retort Water Treatment Methods

In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a

Technological Aspects of Preparing Porridges Made from Local Crops in Mozambique

Popular Abstract in English Malnutrition is one of the problems affecting many developing countries, sometimes leading to disease and death. Complementary foods, especially infant porridges prepared by families in rural areas, are based on plants (cereals, roots and tubers). These porridges are mainly composed of starch, and when mixed with hot water the starch gelatinizes and swells, resulting inChild malnutrition is one of the major health problems in many developing countries and involves many sectors such as health, agriculture and research. Malnutrition in infants usually develops during the introduction of complementary foods, due to a deficit of nutrients, low energy density and the poor bioavailability of vitamins and minerals leading, in turn, to an increase in the risk of disease

Exploring the spread of mass schooling in rural Sweden after the 1842 ‘Folkskole’ reform

A wave of recent research has attempted to explain within-country variations in the rise of primary schooling by studying local political and economic conditions. There is a particular focus on the role of the spread of democratisation and local elites in the development of schooling. An important lesson coming out of these studies is that conditions varied markedly between countries and over time

Precise robot motions using dual motor control

High motion performance, stiffness, and accuracy are crucial for industrial robot applications, but these requirements are in practice contradictory. Using a novel type of robot, the so called Gantry Tau, new combinations of stiffness and accuracy are in principle possible, except for the backlash in the drive-trains of each joint. Existing techniques for backlash reduction are either mechanicall
