A protein combined with phytic acid has been extracted from the dried seeds of Phaseolus vulgaris, variety Great Northern, by the following method. &traction-l00 gm. of bean flour were stirred wit,h 100 ml. of N NaCl, followed by 800 ml. of water. The suspension was centrifuged and the sediment discarded. The pH of the turbid supernatant solution was lowered to 4.6 with about 7.0 ml. of N HCl, ...

The nature of Ni-hydroxide precipitates on pyrophyllite were reexamined by analytical electron microscopy (AEM), high-resolution transmission electron microscopy (HRTEM), selected-area electron diffraction (SAED), powder X-ray diffraction (PXRD), and extended X-ray absorption fine structure (EXAFS) spectroscopy. Chemical analysis of precipitates showed that the precipitate contains about 20% Al...

A comprehensive set of models of precipitate formation during steel processing has been developed. In this work, it is applied to investigate Nb(C,N) precipitation in thin microalloyed steel slabs during continuous casting, reheating in a tunnel furnace and water quenching relative to the position with the slab and alloy content. The models include a transient heat-conduction and solidification...

Precipitate parameters, such as length, diameter and thickness of rationally oriented {100}Al plate/lath-shaped <100>Al rod-shaped precipitates in an age-hardenable Al-Cu-Mg-Si alloy have been examined quantitatively. An appropriate procedure the plate- precipitate separation was suggested to determine parameters well their distribution histograms using bright-(BF) dark-field (DF) transmission ...

I further investigated sample 7 by preparing a precipitate, which I then washed twice in alkaline buffer. The supernate from the first and second washes contained 22.5 and 1.0 mg of albumin per liter, respectively, showing that albumin was recovered from the precipitate. These results indicate that the deposit formed in some urines contains albumin; centrifi.igation of samples may sometimes lea...

The aging process in A1-Li alloys was studied by an atom-probe FIM. Two types of precipitates were recognized in the FIM image, one is brightly imaged with a high degree of order in its structure and the other appeared dark against the Al matrix. Atom-probe analysis showed that the Li concentration is in a range of 10 to 25 at% in the dark precipitate and approximately 25 at% in the bright prec...

Recently, Major R. N. Chopra, i.m.s., Pro| fessor of Pharmacology at the Calcutta School ; of Tropical Medicine, whilst carrying out some j pharmacological experiments with antimony ; compounds, noticed that when the serum from a kala-azar patient was added to certain of the pentavalent compounds of antimony a heavy precipitate was formed. He found that this precipitate was not formed if normal...

Rabbit antiserum was raised against preparations of placental alkaline phosphatase (AP) extracted from human term placentae. The antiserum precipitated AP from the placenta and from the intestine, but it was inactive against AP from bone and liver. The concentration of antiserum required to precipitate intestinal AP was about 10 times higher than that necessary to precipitate placental AP. Plac...

The precipitation titration of sodium chloride with electrogenerated silver ion was studied. The production of a precipitate of silver chloride had a significant effect on the titration results because the precipitate involved unreacted chloride or unreacted silver ion. The accuracy of the method was investigated by changing the introduction time of a sodium chloride solution to the coulometric...
