Indonesia has the potential to develop biomass, such as MSW and wood pellets, a source of energy. Syngas from biomass gasification can be used fuel for dual-fuel diesel engines in order transition We investigated pellets using downdraft reactor with capacity 130–144 kg determine properties produced syngas use engines. Four days are dedicated process preheating sunlight. The experiment was desig...

The hierarchical aggregation of molecular nanostructures from multiple components is a grand synthetic challenge, which requires highly selective linkage control. We demonstrate how two orthogonal groups, that is, organotin and lanthanide cations, can be used to drive the giant metal oxide superstructure. title compound {[(Sn(CH3)2)2O]4{[CeW5O18] [TeW4O16][CeSn(CH3)2]4[TeW8O31]4}2}46− (1 a) fea...

This experimental work studies a small-scale biomass combustor (5–12 kW) with an underfed fixed bed using low air staging ratios (15%–30%). This document focuses on the influence of the operative parameters on the combustion process, so gaseous emissions and the distribution and concentration of particulate matter have also been recorded. The facility shows good stability and test repeatability...

Streptozotocin (STZ) is a bacterial toxin which selectively damages both insulin-producing cells and insulin receptors. Injections of STZ into the cerebral ventricles of experimental animals are followed by sustained biochemical, metabolic and behavioral effects resembling those which are found in human brains afflicted by Alzheimer's disease. The aim of the present study was to assess the effe...

The effect of fuel composition on gasification process performance was investigated by performing mass and energy balances on a pre-pilot scale bubbling fluidized bed reactor fed with mixtures of plastic waste, wood, and coal. The fuels containing plastic waste produced less H2, CO, and CO2 and more light hydrocarbons than the fuels including biomass. The lower heating value (LHV) progressively...

Air pollution control devices (APCDs) are not compulsory for medical waste incinerators (MWIs) in developing countries. In South Africa, combustion gases are usually vented directly to the atmosphere at temperatures greater than the formation temperature of dioxin. The possibility of dioxin formation outside the incinerator stack has been hypothesized. A plume model has been developed and teste...

Regular arrays of rectangular gold nanoparticles on glass substrates are characterized by using linear extinction spectroscopy in the wavelength range of 450–950 nm and nonlinear scanning optical microscopy, in which two-photon photoluminescence TPL excited with a strongly focused laser beam in the wavelength range of 720–800 nm is detected. The dimensions of the nanoparticles 150 150 50 nm3 ar...

Large-scale reconstructions of neuronal populations are critical for structural analyses of neuronal cell types and circuits. Dense reconstructions of neurons from image data require ultrastructural resolution throughout large volumes, which can be achieved by automated volumetric electron microscopy (EM) techniques. We used serial block face scanning EM (SBEM) and conductive sample embedding t...

We present a new computational approach for a class of large-scale nonlinear eigenvalue problems (NEPs) that are nonlinear in the eigenvalue. The contribution of this paper is two-fold. We derive a new iterative algorithm for NEPs, the tensor infinite Arnoldi method (TIAR), which is applicable to a general class of NEPs, and we show how to specialize the algorithm to a specific NEP: the wavegui...
