At the Tip of the Pyramid: The Iconography of Early Astronauts and Cosmonauts
(2012-04-19)
The first American astronauts and Soviet cosmonauts became household names in the midst of proving that human beings could live and work beyond planet Earth. How and why did these men (along with one Soviet woman) achieve ...
Propagation of Vaccinium arboreum by Stem Cuttings for Use as a Rootstock for Commercial Blueberry Production
(2012-04-19)
Commercial blueberries, including V. corymbosum and V. ashei, have very specific needs for optimum growth; hence, growing sites are limited. They require acidic soil (pH 4.0-5.5), good drainage, thorough aeration, and a ...
Estimating Elasticities of Substitution in African Crops
(2012-04-19)
This paper examines cross price elasticities of substitution for labor, capital, and fertilizer for the agricultural sector in Africa with a translog production function. The data are from the Food Agricultural Organization ...
Persistence of fish assemblages on sand and gravel bar habitat in the Alabama River, Alabama
(2012-04-19)
The Alabama River is a biologically diverse system containing over 180 native fishes and at least 33 endemics. Many studies have surveyed species of conservation concern, such as the federally endangered Alabama Sturgeon ...
Competition Graphs
(2012-04-18)
Competition graphs were originally created in 1968 by Biologist Joel Cohen. In this paper we discuss four things. First, the use of linear algebra is considered with connection to competition graphs. Second, we generalize ...
Measurement of the phase space distribution in a complex plasma
(2012-04-18)
The development of a diagnostic technique that allows measurement of the six dimensional phase space distribution for the dust component of a plasma system is presented. In the course of the measurement and analysis ...
Social Desirability, Formation of the Therapeutic Alliance, and Dyadic Adjustment in Couples Therapy
(2012-04-18)
Social desirability has been shown to have both positive and negative associations in the formation of intimate and professional relationships. The purpose of this study was to determine the relationship that social ...
Study of Chicken Egg Qualities Related to Different Protein Level Dietaries and Various Types Of Layers
(2012-04-18)
To determine if strain (brown and white egg shell color type) or diet (16% crude protein, 15% crude protein and 14% crude protein) would affect the component portions of egg, protein composition of albumen, and whether the ...
Chemical Treatments for Reducing the Yellow Discoloration of Channel Catfish (Ictalurus punctatus) Fillets
(2012-04-18)
Three sets of experiments were conducted to investigate effects of various chemical pretreatments on the color and carotenoid changes of yellow discolored channel catfish fillets. First, the relationship between fresh ...
The Economics of Quality in the Specialty Coffee Industry: Insights from the Cup of Excellence Programs
(2012-04-17)
This study estimates price determinants for specialty green coffee auctions using records
from the 2004-2010 Cup of Excellence programs hosted by the Alliance for Coffee Excellence.
Similar to a paper by Donnet et al. ...
Thermal Segregation: Causes and Effects on In-Place Density and Fatigue Performance of Asphalt Mixtures
(2012-04-17)
Previous research has demonstrated that an excessive loss of mix temperature during hauling and paving operations can cause significant reductions in the mix consistency and therefore, in its ability to be compacted ...
Economics of Microbial Inoculants as an Integrated Pest Management Practice in Apple Production
(2012-04-17)
Demographic growth, stricter environmental concerns and regulations, and rising prices
of chemical pesticides emphasize agricultural production alternatives that substitute chemical
input use and increase yields. In ...
Party Polarization: Congressional Divergence on Environmental Policy from 1970-2008
(2012-04-17)
We investigate empirically the importance of a conjectured linkage between economic conditions and increasing party divergence with respect to national-level environmental policy in the United States. Using data from ...
Design of 3.33GHz CML Processor Datapath
(2012-04-17)
Almost a decade processor speed has been stuck at operating frequency 2-3GHz due to excessive power consumption of CMOS logic gate at higher frequency whereas predicted speed at present was 10-15GHz. This leads the idea ...
Investigation of Pile-Up and Delamination of Au Thin Films on Various Substrates and the Behavior of the Films Described by a Discontinuous Elastic Strain Model
(2012-04-17)
A new method of accurately and reliably extracting the actual Young’s modulus of a thin film on a substrate has been developed. The method is referred to as the discontinuous elastic interface transfer model. The method ...
Physicochemical Properties and Thermal Decomposition of Torrefied Woody Biomass and Energy Crop
(2012-04-17)
Torrefaction was performed on pine, sweetgum, and switchgrass to determine its effect on the properties and degradation profiles of the biomass, and the influence of feedstock moisture content on the enthalpy of torrefaction ...
