Photosynthesis is a chemical process through which light energy is used to convert inorganic material (water and carbon dioxide) into organic molecules. Anaerobic photosynthesis, also known as anoxygenic photosynthesis, is the process by which certain bacteria use light energy to create organic compounds but do not adequately involve oxygen. In this experiment we are trying to influence photosynthesis (light and dark reactions: PS-I and PS-II by electron rich gadolinium/iodine complexes like Eovist and Isovue. We also performed X-ray and NIR reflection spectroscopy (NIRS) to measure Gd difusivity and PS-I/II infrared response. The results for X-ray (45kvp and 5 ...

Afterschool interventions in STEM are linked to learning gains during the school day. These opportunities engage and excite students about STEM concepts since they observe a more hands-on, project-oriented approach. Often these opportunities for afterschool interventions are infrequent in nature and leave gaps for students in their maturation and understanding. Herein we describe the first report of an afterschool intervention, named NE STEM 4U, targeting socioeconomically disadvantaged middle school youth via a twice weekly, year-long intervention, studied across two years. We assessed the impact of this program on i.) short-term, individual student gains in STEM content knowledge and ii.) delivery ...

The Family-Environment Connection: Filling A Nationwide Program Gap, Anthony Santiago, Nancy K. Franz, Rebecca Christoffel, Kristi A. Cooper, Brenda K. Schmitt

Education Publications

Since its inception, Extension has focused on helping individuals, families, and communities change economic, environmental, and social conditions. Over the organization's history, environmental condition change programming has been mostly the purview of natural resource educators and less often conducted by family and consumer science professionals. There is no evidence of a comprehensive approach to environmental education in Extension linked to family development. In addition, no evidence was found of any Extension educators conducting environmental education with the family unit as the audience. The Family-Environment Connection initiative created by Iowa State University Extension and Outreach aims to fill this gap.

Sustainability Through Profitability: The Triple Bottom Line, Connie I. Reimers-Hild

Kimmel Education and Research Center - Presentations and White Papers

Today’s highly competitive, globalized world requires organizations and businesses to think differently about how they are going to stay in business. Businesses can no longer afford to focus on profits as their sole purpose for existence. Organizations must instead think about the “Triple Bottom Line” and its implications for their ability to grow their brand, customer loyalty and profits.

The Challenge Of Environmental Protection, Jennifer Mattei Jan 2005

The Challenge Of Environmental Protection, Jennifer Mattei

Biology Faculty Publications

Connecticut is in the midst of a demographic transition to a period of lower population growth. These demographic changes will help check the pressures exerted on the state's natural resources by population growth. Water, air, soil, energy sources, food, fisheries, forests, and biodiversity are common pool resources upon which we depend in ways that transcend political boundaries. Those governing Connecticut should help turn the state into a model of how to manage natural resources by halting forest fragmentation, reducing pollution, and promoting environmental science education.

Nf04-597 Biosecurity And The Poultry Flock, Dan Mcguire, Sheila Scheideler Jan 2004

Nf04-597 Biosecurity And The Poultry Flock, Dan Mcguire, Sheila Scheideler

Historical Materials from University of Nebraska-Lincoln Extension

What is Biosecurity? Biosecurity is a modern term created out of a need to protect, in our case poultry, from an intentional or unintentional threat from a biological agent. In our everyday management, biosecurity is an endless endeavor to keep viral disease agents and/or the spread of such disease agents at bay. We have learned from our own personal welfare that by keeping our environment clean, i.e., "cleanliness is next to godliness" and by reducing contact with infected people or animals, i.e., "being a good neighbor," we can reduce our chance of catching or spreading disease. This ...


Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson Jan 2003

Nf03-570 Fumonisins In Corn, Jim Stack, Michael Carlson

Historical Materials from University of Nebraska-Lincoln Extension

During the past two years, millers have rejected some Nebraska food grade corn because it was contaminated with the mycotoxin fumonisin. Most of the contaminated samples and the highest levels of contamination were detected in corn from counties in the eastern half of Nebraska.

Fumonisins are mycotoxins produced by the grain molds Fusarium verticillioides and Fusarium proliferatum. These fungi are commonly found in corn throughout the United States.

This NebFact discusses the cause and occurrence of fumonisin in corn; the effects it has on plants, animals and humans; and management options to minimize fumonisin contamination.

Nf02-520 Fungicide Spray Schedule For Home Garden Small Fruits, John E. Watkins, Jernnifer L. Chaky

Historical Materials from University of Nebraska-Lincoln Extension

Home grown strawberries, raspberries and grapes are a rewarding experience for the gardener as well as the consumer of the fresh fruits and jellies. If properly managed, these crops can be a source of enjoyment for years. To be successful, however, the home gardener must develop a sound integrated pest management (IPM) approach to controlling diseases and insect pests. A good IPM program makes use of cultural, varietal and chemical means of preventing or reducing disease losses.

This NebFact discusses which fungicides to use for which disease of small garden fruits and provides recommendations for a fungicide treatment schedule.

G00-1778 Field Windbreaks, James R. Brandle, Laurie Hodges

Historical Materials from University of Nebraska-Lincoln Extension

gricultural producers face many challenges as they try to balance efficient production systems with increasing environmental demands. For these systems to be successful, they must optimize the balance between inputs and final production. Field windbreaks are one way to increase yields while at the same time reducing inputs and improving both environmental quality and production efficiency. Windbreaks reduce wind speed and alter the microclimate in sheltered areas. Field windbreaks reduce wind erosion and the damage to crops caused by wind-blown soil. They improve water use efficiency, reduce risks associated with drought, and manage blowing snow.

Field windbreaks provide positive economic ...
