Addressing Issues Surrounding Food Insecurity And Promote Environmentalism In Urban Settings Using Community Gardens, Tucker Jensen

School of Education and Leadership Student Capstone Projects

This capstone project reviews the effect community gardens have on the low-income, urban population. After reviewing the history of racism in America, disproportionalities of food insecurity, how poverty correlates to health, and various environmental impacts specific to urban communities, this project was an effort to expand on that research and provide a solution. Food deserts exist in many of today’s American cities, which lead to food insecurity and negative health outcomes. A community garden is a low-cost, effective way to obtain healthy food and simultaneously benefit the environment. This five-day unit of study takes place at an established community garden. …

The Trait Repertoire Enabling Cyanobacteria To Bloom Assessed Through Comparative Genomic Complexity And Metatranscriptomics, Huansheng Cao, Yohei Shimura, Morgan M. Steffen, Zhou Yang, Jingrang Lu, Allen Joel, Landon Jenkins, Masanobu Kawachi, Yanbin Yin, Ferran Garcia-Pichel

NIU Bibliography

Water bloom development due to eutrophication constitutes a case of niche specialization among planktonic cyanobacteria, but the genomic repertoire allowing bloom formation in only some species has not been fully characterized. We posited that the habitat relevance of a trait begets its underlying genomic complexity, so that traits within the repertoire would be differentially more complex in species successfully thriving in that habitat than in close species that cannot. To test this for the case of bloom-forming cyanobacteria, we curated 17 potentially relevant query metabolic pathways and five core pathways selected according to existing ecophysiological literature. The available 113 genomes …

The Effects Of Milk Components On Lactoperoxidase Activity, Leonard Fweja, Michael Lewis, Alistair Grandison

Tanzania Journal of Science

This study examined the effects of storage conditions (in particular temperature and media composition) and changes in composition of each milk fraction, and of individual components on lactoperoxidase (LP) activity. The enzyme demonstrated a pulsing characteristic especially in samples stored at 5 °C, however, temperature and media composition did not have great effects on the pulsing behaviour of the enzyme. The results also indicated small but statistically significant variations (P ≤ 0.05) in LP activity between whole milk (control) and acid whey, rennet whey and cream and non-significant variations (P > 0.05) between the control and skimmed milk, and between skimmed …

In the first stage, 200 respondents in Serengeti District of Mara region were exposed to the 13 items of PSE scale, while in the second the adopted tool with 11 items was administered to a total of 360 participants in Mara, Mwanza, …

Removal Of Iron And Manganese From Groundwater: A Study Of Using Potassium Permanganate And Sedimentation., Mahmoud Elsheikh, Hany Guirguis, Abd El-Rahman Amer

Mansoura Engineering Journal

This paper studies the efficiency of iron (Fe+2) and manganese (Mn+2) removal from groundwater using oxidation by potassium permanganate followed by filtration and using conventional treatment consisting of flocculation, sedimentation and filtration. Experiments were done for different combinations of Fe+2 and Mn+2 concentrations. The obtained results show that Potassium Permanganate (PP) gives good results. By using PP dose equals to half of the theoretically required one, it can remove up to 100% and 90% of iron and manganese respectively over different tested concentrations at pH=7.0. Increasing rate of filtration decreases the Mn+2 removal efficiency obviously. Sedimentation is required when combined …

Are We Producing Society-Ready Foresters? A Quantitative Content Analysis Of Graduate-Level Forestry Curriculum, Jacqueline Meyer

The Pegasus Review: UCF Undergraduate Research Journal

Forestry education in the United States has been hailed for its ability to provide students with the scientific and technical skills needed for a career in forestry as much as it has been criticized for ignoring social dimensions of the discipline. Its inability to adapt curriculum to the increasingly multidisciplinary nature of the forestry profession has led to stagnant or decreasing enrollment and lack of student diversity in recent years. While forestry education and curriculum has been thoroughly analyzed at the undergraduate level, no such analysis exists for graduate curriculum. This study analyzes the course content of 40 graduate-level forestry …

Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven

Harold W. Manter Laboratory of Parasitology: Library Materials

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …
