were treated with 7.5 N potassium hydroxide. The gases produced in the reaction were carried through standard sulphuric acid to absorb the ammonia and the remaining gas was collected over mercury by means of a Toepler pump. The residue remaining in the reaction tube was analyzed for gallium. (4) Analysis for Nitrogen: substance, 0.1619, 0.2141; cc. 0.09367 N H2SO4, 13.15, 17.38; % N found, 10.66, 10.65, mean 10.65; % N required for (CH3)3Ga.NH3, 10.63. (5). Analysis for Gallium: substance, 0.1619, 0.2141; Ga203, 0.1152, 0.1525; % Ga found: 52.93, 52.98, mean 52.95; % Ga required for (CH3)3Ga NH3, 52.89. (6) Methane Determination: m. mols (CH3)3Ga-NH3, 1.23, 1.63; cc. of gas, 27.4, 56.9; mol. wt., 16.3, 16.3; m. mols. CH4, 1.22, 1.64. Hydrolysis evidently occurs according to the equation: (CH3)3Ga.NH3 + KOH = (CH3)2GaOK + CH4 + NH3. 1 DUPONT FELLOW in Chemistry. 2 Dennis and Patnode, Jour. Amer. Chem.

The F-actin-microtubule crosslinker Shot is a platform for Krasavietz-mediated translational regulation of midline axon repulsion.
Axon extension and guidance require a coordinated assembly of F-actin and microtubules as well as regulated translation. The molecular basis of how the translation of mRNAs encoding guidance proteins could be closely tied to the pace of cytoskeletal assembly is poorly understood. Previous studies have shown that the F-actin-microtubule crosslinker Short stop (Shot) is required for motor and sen...
متن کاملKnowledge Recognition Algorithm enables P = NP
This paper introduces a knowledge recognition algorithm (KRA) that is both a Turing machine algorithm and an Oracle Turing machine algorithm. By definition KRA is a non-deterministic language recognition algorithm. Simultaneously it can be implemented as a deterministic Turing machine algorithm. KRA applies mirrored perceptual-conceptual languages to learn member-class relations between the two...
متن کاملA Propound Method for the Improvement of Cluster Quality
In this paper Knockout Refinement Algorithm (KRA) is proposed to refine original clusters obtained by applying SOM and K-Means clustering algorithms. KRA Algorithm is based on Contingency Table concepts. Metrics are computed for the Original and Refined Clusters. Quality of Original and Refined Clusters are compared in terms of metrics. The proposed algorithm (KRA) is tested in the educational ...
متن کاملRenin-angiotensin system in spontaneously hypertensive rats.
Plasma and kidney renin activities (PRA, KRA) were determined in male spontaneously hypertensive rats (SHR), the inbred strain of F27-30. Blood samples of 0.5 ml for PRA determination were obtained through a cannula inserted into the abdominal aorta without anesthesia to minimize renin release from the kidney. The PRA was 30 wk. The KRA of SHR at age 10, 20, and 30 wk was also lower, confirming...
