Using petroleum ether to extract the fermentative fluid (bio-slurry), then to get the inhibition mechanism of it, and infer which is the main component in inhibition mechanism of biogas. The conclusion found by the experiment is that fat soluble substance is better than water soluble substance in inhibition mechanism, and fat soluble substance is close to 75% biogas fermentation fluid, while water soluble substance is worst. That is to say, the main subject in inhibition mechanism is hided in the fat soluble substance.

Main Component

Water-soluble substance is an important part of non-rubber substance in natural rubber latex and it has significant influence on the properties of natural rubber. The aim of this paper is mainly to study the composition of small-molecular-weight water-soluble substance (s-WSS) and its effects on the properties of natural rubber films. The analysis of IR and HPLC-MS showed that s-WSS (not including sugar) is composed of C3H4N4O6, C7H14O6, C11H13N3O5, C11H20O7 and C6H22N8. While the main component of s-WSS is C7H14O6 whichis a kind of alcohol. The tensile strength of the prepared composites can be increased at low loading of s-WSS. The tear strength of the prepared composites can be improved by adding s-WSS into natural rubber. The thermal oxidation degradation process of the samples has two stages. Compared with neat natural rubber latex, the initial degradation temperature was decreased significantly in both stages when s-WSS was added. While the degradation temperature range became larger in both stages.

Maple Sap

Skazin's observation that maple flavor is not present as such in sugar maple sap but develops at boiling temperatures (100–104 °C.) has been confirmed. Levorotatory glucosides cannot be detected in sap concentrated to 1/150 its volume, and are therefore probably not present in amounts exceeding 1 gm. (calculated as coniferin) per 50 litres. In maple wood, pyrocatechol tannins were detected but no alcohol-soluble glucosides. The sap contains succinic acid, a glucosidase, an unsaponifiable oil, a water-soluble substance melting at 191.5 °C. and having the composition C11H21O9, and an acetone-soluble substance giving lignin-like color tests. Maple flavor could not be developed in any individual constituent of the sap.

Do So

Yellow birch seeds were found to vary in size directly as the strobilus on which they are borne and to increase in size within the strobilus directly as their point of origin is removed from either end. Viability was found to vary from 0% to 34% of the seeds on an individual tree. The best method of determining viability is examination of the embryo following dissection of the seed. A valid test of viability is given by 2,3,5-triphenyltetrazolium chloride, but this is not recommended because of the small size of the embryos. It is shown that the seed coats contain a water soluble substance that inhibits growth of the embryos. This substance loses its inhibiting properties when exposed to extended periods of light, but the injury to the embryo is permanent. It is suggested that trees producing few viable seeds in a seed crop may do so because this species is not functionally monoecious and that pollination difficulties would account for a small number of viable seeds on partly isolated trees.

Fine Print

✓ Meglumine iothalamate 60% (Conray) is a water-soluble substance being developed for the roentgenographic visualization of the cerebral ventricular system. Although it offer definite advantages compared to other contrast media, a recognized disadvantage is the possible development of seizures. This complication seems to be relatively rare and largely preventable, but once present may seriously endanger the patient's life. It appears to be a neurotoxic phenomenon, resistant to the usual anticonvulsant medications, and requires the availability of sophisticated personnel and emergency procedures to prevent death.

Possible Cause

Re-use of hemodialysers diminishes the extent of leucopenia observed during hemodialysis. A possible cause of this change is the prolonged washing of the membrane by an aqueous solution on both sides and by protein contained solutions on the blood side which removes some substance from the membrane which affects leucocytes directly or by activation of complement. A series of studies to test this hypothesis were performed using two hemodialysis membranes -Cuprophan (Enka AG) and Cellulate (Cordis Dow Corporation) and the results obtained demonstrate no elution of any water soluble substance from the dialyser membrane.
