Alkali is a problematic component in biomass and may create various operation issues normal combustion as well chemical looping using fuels (bio-CLC). To investigate the interaction of alkali with an oxygen carrier, methodology has been developed where salts are added impregnated charcoal particles. This work studies effect K2CO3 Na2CO3 on fluidization/agglomeration behavior reactivity braunite...

BACKGROUND The case fatality for intentional self-poisoning in rural Asia is 10-30 times higher than in the West, mostly due to the use of highly toxic poisons. Activated charcoal is a widely available intervention that may - if given early - bind to poisons in the stomach and prevent their absorption. Current guidelines recommend giving a single dose of charcoal (SDAC) if patients arrive withi...

The pyrolysis of briquettes made from biomass is an available and economic technological route for the production of briquette charcoal, but by-products (tar and gas) cannot be brought into full utilization, leading to the waste of resources and the addition of environmental concerns. Temperature is the most important parameter that affects the distributions and properties of briquette charcoal...

Wood and charcoal fuels, widely used in Sierra Leone for cooking, may impact indoor air quality. Until now, there is presently lack of data to quantify the extent of impact. In this study, concentrations of polycyclic aromatic hydrocarbons (PAHs), suspended particulate matter (SPM) and carbon monoxide (CO) were measured in kitchens with wood and charcoal stoves during cooking in rural areas. PA...

Recent work in non-photorealistic rendering (NPR) has found methods to render various artistic effects like pen and ink illustrations, pencil sketching, water color, engraving, and silhouette rendering. In this paper, we present a new algorithm to achieve the effects of charcoal rendering in real-time using contrast enhancement operators. Charcoal is a medium that has limited dynamic range and ...

Salmeterol is approximately eight times as potent as salbutamol for systemic effects. This may be because the drug is eight times more potent on receptors or there may be differences in systemic bioavailability. The systemic effects of salbutamol are limited by its fairly high first-pass metabolism, but the oral bioavailability of salmeterol is unknown. The contribution of the swallowed fractio...

BACKGROUND Charcoal burning in a sealed room has recently emerged as the second most common suicide means in Hong Kong, causing approximately 200 deaths each year. As charcoal burning suicide victims have a unique sociodemographic profile (i.e., predominantly economically active men), they may commit suicide at specific times. However, little is known about the temporal patterns of charcoal bur...

I N PREVIOUS REPORTS’3 it was shown that uncoated charcoal adsorbs both free vitamin B12 and B12 bound to proteins, but charcoal precoated by mixing with saturating quantities of albumin adsorbs only free B12. This finding has been confirmed.4 The charcoal particles may be considered as solid microsponges and the albumin coat as a molecular sieve surrounding each sponge. Small molecules such as...

Bg CHESTER GorruEB, KAM-SENG LAU, Louis R. \VASSERMAN AND VICTOR HERBERT T HIS COMMUNICATION reports the use of protein-coated charcoal iii rapid assays for: (1) intrinsic factor (IF), (2) unsaturated B12 binding capacity of gastric juice, (3) antibody to IF, and (4) serum unsaturated B12 binding capacity. The assays are based on the finding that charcoal precoated with a large molecule can ads...

introduction: a major concern of human being is accumulation and toxicity of heavy metals in their body. copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. different treatment methods have been proposed for removing metals from contaminated water by researchers. among these methods, sorption seems a better method with high removal efficiency. in this s...
