Cyanoacrylates and their acid values
International Journal of Adhesion and Adhesives, 1993Abstract Polymerization of cyanoacrylate monomer is usually initiated by the film of moisture present on the surface of the substrate to be bonded, the water neutralizing the weak acid added to inhibit the anionic polymerization reaction. In this paper, the effect of acid value on the time for polymerization of eight commercial cyanoacrylate ...

THE VALUE OF FOLIC ACID SUPPLEMENTS IN PREGNANCY
BJOG: An International Journal of Obstetrics & Gynaecology, 1971SummaryIn a double‐blind trial of folic acid supplements (5 mg. per day) during pregnancy‐no effects were seen in the incidence of anaemia or complications of pregnancy, although the serum folate levels were less abnormal in the treated group. Nor was evidence found that anaemia or serum folate levels determined the incidence of complications and the ...

The thiocyanogen value of linolenic acid
Oil & Soap, 1940Ethyl linolenate (Wijs iodine number 247.3; theory 248.5) was prepared by the debromination of purified hexabromostearic acid. The thiocyanogen value determined exactly as recommended by the Committee on Analysis of Commercial Fats and Oils, [Ind. Eng. Chem. Anal.

Diagnostic Value of Serum Bile Acids
Clinics in Gastroenterology, 1977With the development of simplified methods of bile acid analysis, a new era has drawned in the evaluation of hepatobiliary disease. 1. A total serum bile acid particularly in the postprandial periods is more sensitive than either BSP or ICG for the detection of minimal liver disease and will become a useful screening method. 2.

Errors in the acid and saponification values of fatty acids
Journal of the American Oil Chemists' Society, 1962AbstractAttention is directed to the variation in ester value of fatty acids depending upon method of isolation. The formation of sterol esters increases the ester value of fatty acids. The increase of ester value with elapsed time is discussed. The effect of ester value variation on the results obtained in soap analysis is described, and a possible ...

Directly derived from renewable biomass, i.e. plant oils and animal fats, fatty acids present themselves as polar molecules with a hydrophobic hydrocarbon chain and only two different reactive centres, a carboxyl group and olefinic double bonds. This structure makes them suitable as platforms for chemical effect species as diverse as green solvents ...

IOPHENOXIC ACID AND SERUM-BOUND IODINE VALUES
JAMA, 1960In 1957, Astwood 1 reported on a patient with hyperthyroidism whose serum-bound iodine level was 4,200 meg. per 100 ml. A single dose of radioactive iodine led to a clinical remission of the hyperthyroid state but the bound iodine level in the serum remained astronomically elevated.

The Scientific Value of Carbonic Acid
Transactions of the Kansas Academy of Science (1903-), 1930There are two acids with which the geologist must become acquainted before he can understand the main chemical activities in the crust of the earth. These are conbonic acid and silicic acid. Carbonic acid is active in the colder, outer parts of the earth and silicic acid prevails in the deeper, hotter parts of the earth.

Summary: Objective: In this study, we aimed to evaluate the diagnostic value of the HALP score, serum uric acid value, and uric acid-creatinine ratio, which are inflammatory markers, in the diagnosis of preeclampsia (PE). Materials and methods: One hundred sixty-six pregnant women who met the inclusion and exclusion criteria were included in the study.
