2014 Honors graduate Peter Horning, who wrote his thesis on prosthetics, is now in Haiti on an internship at a prosthetics clinic

Living Below the Line: Economic Insecurity and America's Families

Since the onset of the Great Recession, the nation has been focused on a steady stream of mostly discouraging unemployment, poverty and housing foreclosure numbers. While this data is important, it tells us only about those suffering the most severe of financial crises. It does not help identify the millions within the United States who live above the poverty line and yet struggle to pay ever-increasing housing, food, health care and other expenses. Wider Opportunities for Women (WOW) has compared working-age adults' earnings and household incomes to The Basic Economic Security Tables (BEST) for the United States, a measure of the basic needs and assets workers and their households require for economic security. This report compares pre-tax incomes from 2007 through 2011 to BEST basic needs budgets for more than 400 family types,and finds that approximately 45% of Americans live on incomes that fail to provide basic economic security.This report identifies who, specifically, within the United States is living below the BEST Indexes. It tells an important story about the contemporary value of work and the relationship between economic security and gender, race/ethnicity, family structure and education

Pneumatic shutoff and time-delay valve operates at controlled rate

Shutoff and time delay valve, which incorporates a metering spool that moves at constant velocity under pneumatic pressure and spring compression, increases fluid-flow area at a uniform rate. Diaphragm areas, control cavity volume, and bleed-orifice size may be varied to give any desired combination of time delay and spool travel time

Related Studies in Long Term Lithium Battery Stability

The continuing growth of the use of lithium electrochemical systems in a wide variety of both military and industrial applications is primarily a result of the significant benefits associated with the technology such as high energy density, wide temperature operation and long term stability. The stability or long term storage capability of a battery is a function of several factors, each important to the overall storage life and, therefore, each potentially a problem area if not addressed during the design, development and evaluation phases of the product cycle. Design (e.g., reserve vs active), inherent material thermal stability, material compatibility and self-discharge characteristics are examples of factors key to the storability of a power source

A Spatial and Multivariate Approach to Examining Effects of Urbanization on Nitrogen Sources, Organic Matter Inputs, and Trophic Structure in Streams of Cobb and Paulding Counties, Georgia.

Urbanization and land use changes have a negative effect on streams often causing numerous physical changes in stream morphology, a change in nutrient concentrations, and altered ecosystems contributing to a loss of habitat, decreased biodiversity, and loss of stability for ecosystem function (Walsh et al., 2005; Meyer et al., 2005; Cardinale and Palmer, 2012). The use of stable isotope analysis for monitoring could be valuable because it accounts for temporal integration from anthropogenic wastewater inputs, characterized by a shift in the abundance of 15N. This project had three main objectives: (1) to examine how nitrogen and carbon sources are altered with the use of spatial trends of δ15N values in streams with varying levels of urbanization; (2) to examine how the effects of urbanization, altered nitrogen and organic matter inputs play a role in trophic structure within aquatic ecosystems by examining isotopic food webs; and (3) to see if these variables could be utilized for spatial predictability of urban impacts on streams. We found support for the notion that high levels of developed land use and agricultural land use correspond with an increase in the ẟ15N values of macroinvertebrates. Our food webs and ẟ15N values suggested that certain organisms changed their role in the food web consistent with a shift in the food web towards omnivory. Use of impervious surface area, land cover land use and ẟ15N to monitor water quality could provide an early indicator for stream degradation

TAXATION-PERCENTAGE DEPLETION ALLOWANCE ON INCOME RECEIVED FROM THE REWORKING OF DUMPS AND TAILINGS DEPOSITS

A dump of waste material and low-grade ore resulted from mining operations by a lessee in the American Mine. London Extension owned an undivided one-half interest in the claims which made up the mine. In 1940 London acquired the lease on the property. Chicago Mines, a wholly-owned subsidiary of London, then took a lease on the dump, agreeing to pay to London a royalty of twenty per cent of the net smelter returns. Chicago worked the dump for a few months, after which it was worked by London. In filing its income tax return for the year, Chicago claimed a percentage depletion allowance on account of its working of the dump. London claimed a percentage depletion allowance based on the amount it received from Chicago as royalties, plus the amount it received from its own working of the dump. On appeal from a Tax Court decision adverse to the taxpayer, the Court of Appeals for the Tenth Circuit held that the controlling question was whether or not the dump was a mine within the meaning of section 23(m) of the Internal Revenue Code. The court found that the dump was not a mine and therefore the depletion allowance was not available. Chicago Mines Co. v. Commissioner, (10th Cir. 1947) 164 F. (2d) 785
