Effect of Reaction on the Growth of Yeasts
A study was made to determine the amounts of organic acids necessary to inhibit the growths of some yeasts isolated from bottled beverages. It was found that, in a medium containing the same amount of cane sugar used in bottled beverages (10%), with 0.1% peptone as a source of nitrogen and made solid with 2% agar agar, it was necessary to add sufficient acid to give a pH value of 3.3 to 2.6 in order to inhibit the growth of five strains of yeasts of variable sensitiveness. In a similar medium without the agag, acid to give a pH value of 2.7 to 2.3 was required for inhibition of growth

A.P. Giannini, Marriner Stoddard Eccles, and the Changing Landscape of American Banking
The Great Depression elucidated the shortcomings of the banking system and its control by Wall Street. The creation of the Federal Reserve System in 1913 was insufficient to correct flaws in the banking system until the Banking Acts of 1933 and 1935.
A.P. Giannini, the American-Italian founder of the Bank of America and Mormon Marriner S. Eccles, chairman of Federal Reserve Board (1935-1949), from California and Utah respectively, successfully worked to restrain the power of the eastern banking establishment. The Banking Act of 1935 was the capstone of their cooperation, a bill that placed open market operations in the hands of the Federal Reserve, thus diminishing the power of the New York Reserve. The creation of the Federal Housing Act, as orchestrated by Eccles, became a source of enormous revenue for Giannini. Giannini's wide use of branch banking and mass advertising was his contribution to American banking. Eccles's promotion of compensatory spending and eventual placement of monetary control in the hands of the Federal Reserve Board with Banking Act of 1935 and the Accord of 1951 and Giannini's branch banking diminished the likelihood of another sustained depression.
As the Bank of America grew, and as Eccles became more aggressive in his fight for control of monetary policy, Secretary of State Henry Morgenthau, Jr., became a common enemy to both bankers. Morgenthau caused the Securities and Exchange Commission to launch an investigation of the Bank of America. Later, when Eccles and Giannini were no longer friends, the Board of Governors filed suit under the Clayton Act against Transamerica, a Giannini bank holding company.
By 1945, Giannini's bank was the largest in the world. When John W. Snyder replaced Morgenthau, the "freeze" against Giannini's expansion stopped. Eccles was demoted by Truman but served on the Board of Governors until the Accord of 1951 making the Reserve no longer responsible for supporting the pegged interest rates of government bonds
IMPACT OF HUMAN CHARACTERISTICS IN BASIC UNDERWATER DEMOLITION/SEAL (BUD/S) TRAINING PERFORMANCE
Reporting and clerical functions at Naval Special Warfare (NSW) Echelon IV commands are ripe for digitization, automation, and optimization. This study utilizes a restricted digitalized NSW dataset to showcase how “big data” in the context of SEAL training can be used to predict performance success of various Basic Underwater Demolition/SEAL (BUD/S) training evolutions. Our study focuses on multiple human characteristics and compares their correlation to evolution pass rates in training using Ordinary Least Squares (OLS) for our prediction model. From our initial regression analysis of over 232,000 data points, our findings indicate higher pass rates for BUD/S candidates who are older, married, and officers, as well as increased pass rates in individuals who were taller, lighter, and right-handed. Lower pass rates are found among minorities. The Black population had high fail rates in the evolutions that involve water activities. This study is an example of how long-term efficiencies could be gained from greater automation of data using simple software that could provide long-term benefit if captured in a more persistent and accurate manner. We advocate for the implementation of a more automated data/software collection system that can capture each student's training career in one cohesive data profile. Moving forward, NSW studies should continue to leverage the use of “big data” to optimize its performance across all domains of the force.Approved for public release.

MIRTO: an open-source robotic platform for education
This paper introduces the MIddlesex RoboTic platfOrm (MIRTO), an open-source platform that has been used for teaching First Year Computer Science students since the academic year 2013/2014, with the aim of providing a physical manifestation of Software Engineering concepts that are often delivered using only abstract or synthetic case studies. In this paper we provide a detailed description of the platform, whose hardware specifications and software libraries are all released open source; we describe a number of teaching usages of the platform, report students’ projects, and evaluate some of its aspects in terms of effectiveness, usability, and maintenance
