The present status of plastics is one of constant change, but
this thesis attempts to focus attention on the state of the industry as of
1967. Beginning with a brief title definition and history of plastics,
the writer proceeds to a discussion on the structural characteristics
of plastics. Under this...
Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
1) Develop and moderate a workshop to discuss hypothetical crop rotation strategies that would
allow conversion of land to organic processed vegetable production without exacerbating weed
or pest positions.
• Invite industry leaders to help develop crop rotations
• Invite potential forage consumers/buyers to help focus on projected forage needs...
The Alaska non-pollock multi-species catcher processor trawl fishery, referred to as the Amendment 80 fishery since 2008, is an endlessly fascinating subject from the perspective of an economist. A diverse group of companies and vessels, emphasizing different species mixes from a multi-species ecosystem, targets fish across the Eastern Bering Sea,...
Generalisation is a key component of mathematical activity. Mathematicians often seek general formulae or wonder if a rule that holds in a particular dimension also holds in dimension n. However, generalisation is not limited to professional mathematicians; kindergarteners engage in generalisation when they seek patterns and algebra is sometimes described...
The antigens of eight isolates of Renibacterium
salmoninarum were compared serologically using
immunoelectrophoretic techniques. Seven common antigens
were identified by their electrophoretic mobilities in each
antigenic profile. One of these common antigens, designated
Fr 21-30, was partially purified by ammonium sulfate
precipitation and gel filtration. Cross adsorption analysis
showed Fr...
Strip tillage is a form of conservation tillage that involves tilling
narrow strips for crop establishment while leaving areas between the strips with undisturbed crop residue. Strip tillage can reduce soil erosion and soil compaction, as well as machinery, fuel, and labor costs. Combined with winter cover crops, strip tillage...
The rise of digital streaming has largely impacted the way the average listener consumes music. Consequentially, while the role of album art has evolved to meet the changes in music technology, it is hard to measure the effect of digital streaming on modern album art. This research seeks to determine...
Climate change, population growth, aging infrastructure, poor water management, and aquifer depletion are reducing US water supply. Increasing water scarcity will lead to an inability to support agriculture, industry, energy, and municipal demand that will negatively affect US economic growth and national security. Traditional water policy measures of expanding supply...
