Using Rice Husks in Water Purification in Brazil

Rice husk, which considered a waste, has a high level of silicon. This paper investigates the use of carbonized rice husk in water purification. The carbonization was done using a handmade carbonizer. The preparation process starts with the production of a precursor that is rich in carbon through the pyrolysis of the rice husk in an inert atmosphere. The results show an important contribution of t

Using an Evolutionary Algorithm in Multiobjective Geographic Analysis for Land Use Allocation and Decision Supporting

Usually, allocation of resources is an optimization problem which involves a variety of conflicting economic, social, and ecological objectives. In such a process, advanced geographic analyst tool for manipulation of spatial data and satisfaction of multiple objectives is essential to the success of decision-making. The present research intends to demonstrate the application of a multiobjective op

Congenital muscular dystrophy with laminin α2 chain-deficiency. Initiation of disease and development of treatment

Congenital muscle dystrophy type 1A (MDC1A) is a muscle disease caused bymutations in the LAMA2 gene, encoding the basement membrane protein lamininα2 chain. MDC1A patients exhibit neonatal onset of muscle weakness, progressivemuscle wasting and hypotonia, joint contractures that mostly affect elbows, hips,knees and ankles along with scoliosis and delayed motor milestones. Currently,there is no cu

Experimental Investigation of the Effect of Steam Dilution on the Combustion of Methane for Humidified Micro Gas Turbine Applications

Water introduction in the micro gas turbine (mGT) cycle is considered the optimal route for waste heat recovery and flexibility increase of such a small-scale combined heat and power (CHP) unit. However, humidification of the combustion air in a mGT affects combustion stability, efficiency, and exhaust gas emissions. This can lead to a non-stable, incomplete combustion, which will affect the globa

Hur stor är en rimlig statsskuld för Sverige?

Hur stor bör den svenska statsskulden vara? I dag finns en livlig debatt kring frågan, knuten till överskottsmålets vara eller inte vara. Den ekonomiska litteraturen ger inget klart svar. Storleken på den ”optimala” eller lämpliga statsskulden beror på både vilken teori eller riktlinje som är utgångspunkten och vilken empirisk metod som används. Vi argumenterar för att statsskulden mätt som Maastr

The 2005 London terror attacks : An investigation of changes in psychological wellbeing and social capital pre- and post-attacks (2003-07)-A UK panel study

The London public transport suicide bombings, which occurred on 7th July 2005, were described as the worst single terrorist atrocity on British soil to date. Past acts of terrorism have been associated with deterioration in population mental health. They may also negatively impact levels of social capital, which is considered a buffer against poor mental health outcomes. By employing panel data fr
