The fatty acid contents of 26 different serum albumin preparations representing different species and obtained from various commercial sources have been determined. Some samples had surprisingly little fatty acid contamination, but it was found that other samples contained between 2 and 3 moles of acid per mole of protein, in confirmation of earlier reports. Treatment of these samples with char...

In 2002, the Biscuit Wildfire burned a portion of the previously established, replicated conifer unthinned and thinned experimental units of the Siskiyou Long-Term Ecosystem Productivity (LTEP) experiment, southwest Oregon. Charcoal C in pre and post-fire O horizon and mineral soil was quantified by physical separation and a peroxide-acid digestion method. The abrupt, short-term fire event caus...

This method depends upon the use of formalindenatured gelatin with finely powdered charcoal incorporated as an indicator of liquefaction. The gelatin charcoal is used only as a substrate for testing the gelatinase activity and not as a nutrient medium. This substrate contains a large number of minute particles of charcoal with a comparatively small amount of gelatin as binding substance. Conseq...

The addition of pyrogenic carbon (C) in the soil is considered a potential strategy to achieve direct C sequestration and potential reduction of non-CO2 greenhouse gas emissions. In this paper, we investigated the long term effects of charcoal addition on C sequestration and soil physico-chemical properties by studying a series of abandoned charcoal hearths in the Eastern Alps of Italy establis...

A B S T R C TCoconut shell charcoal briquettes have a better quality than from other biomass. However, this briquette also has weakness, namely slow initial ignition. This study aimed to analyze the and ignition characteristics of coconut coated with sengon on both surfaces. The research materials were wood obtained Makassar city, South Sulawesi. Firstly, shells charcoaled. Coconut then ground ...

Charcoal is one of the important energy sources in the developing countries. Additionally, it is effective not only in carbon fixation and inactivation in the atmosphere but also in environmental conservation when used as an agent such a soil conditioner or growth accelerator of plants. However the utilization of charcoal in forestry sector, especially industrial plantation, has not been introd...

In Haiti, wood and wood charcoal are common fuels for cooking. This practice has contributed to deforestation, leading to erosion and fatal floods. The availability of charcoal made from a different source other than wood, such as agricultural waste, might provide Haitians with an alternative, more sustainable fuel, which in turn may reduce fuel prices. MIT students have developed various metho...

Introduction: Adsorption capacity of activated charcoal to paracetamol was determined at simulated gastric environment, pH 3.4 and simulated intestinal environment pH 7.2. Three formulations of activated charcoal; powder, capsule and suspension were tested. Paracetamol was derived from tablet to simulate in vivo intoxication conditions. Methods: Activated charcoal and paracetamol were mixed at ...

UNLABELLED PREMISE OF THE STUDY Charcoal particles preserved in sediments are used as indicators of paleowildfire. Most research focuses on abundance as an indicator of fire frequency, but charcoals also convey information about the vegetation from which they are derived. One potential source of information is their morphology, which is influenced by the parent material, the nature of the fi...

OBJECTIVES Following the first case in Hong Kong in 1998, the method of committing suicide by charcoal burning has spread to other communities. This aim of this study was to examine the impact of charcoal burning suicides on both overall suicide rates and older-method suicide rates in Hong Kong and urban Taiwan. DESIGN Trend analysis of the overall and method-specific suicide rates between 19...
