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...

Provision of Solid Made from Oil Palm Empty Fruit Bunches and Rice Husk Charcoal on Production Tomato Plants (Solanum Lycopersicum L) aims to determine the effect various types (Oil Bunches) L). This research was conducted in Sona Village with an altitude 18 meters above sea level Labuhanbatu Regency December 2019 March 2020. The material used tomato seeds, husk charcoal, solid water. equipment...

The use of isotope ratio infrared spectroscopy (IRIS) for the stable hydrogen and oxygen isotope analysis of water is increasing. While IRIS has many advantages over traditional isotope ratio mass spectrometry (IRMS), it may also be prone to errors that do not impact upon IRMS analyses. Of particular concern is the potential for contaminants in the water sample to interfere with the spectroscop...

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 ...

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...
