Introduction: Ageratum houstonianum is an herbaceous, drought-tolerant plant also known as Blue billygoat weed. It grows well in drained soil and shaded areas. Soil moisture and porosity are two abiotic factors that affect the abundance and distribution of A. houstonianum. An ideal condition for plants to grow includes a greater amount of soil moisture and porosity. Higher porosity would mean that there is a greater number of pores, which would result in more significant plant nutrients because of its ability to retain more water. The purpose of this research was to see how soil moisture and porosity based on …

When engineers and biologists work together, there is a lot to learn on both sides. For instance, our work introduced us to zugunruhe, which is a German word that means “unrest”. It is used in the context of migratory birds, as they become restless at night, inside their cages, during their migratory period. When does zugunruhe start? It usually starts when the weather becomes cold and the days shorter, but it varies for different bird species. Moreover, global warming has caused changes in zungunruhe’s timing, which made it even harder to predict. Another question is about genetics: is …

Egyptian spinach (Corchorus olitorius, L.) is an annual herb and a popular vegetable grown in the dry, semi-arid and humid regions of Africa. It belongs to the American basswood family and is very nutritious, and known to have medicinal properties as well. Introducing Egyptian spinach as a specialty crop in Texas requires examining and determining the best cultural practices needed for its successful production. The objective of this study was to determine the effects of three nitrogen fertilizer rates on the growth of Egyptian spinach grown under greenhouse conditions. We hypothesized that the yield of Egyptian spinach will …

Cellular respiration is the process by which organic matter oxidizes, and the energy stored in the chemical bonds of the food releases. Normally, cellular respiration occurs inside the mitochondria of cells; however, a unique type of bacteria releases electrons externally. These specialized organisms are called electrogenic bacteria. Our goal is to construct a microbial fuel cell (MFC) with electrogenic bacteria, harvest the external electrons created by cellular respiration, and channel them through an external circuit to generate electricity. Mud soil, which has a high number of electrogenic bacteria in the environment, was used to construct an MFC. In the presence …

Background: Zoonotic diseases are problematic, in that, they impact both wild and domestic animals alike. Thus, there is a need to investigate the genomes of wild and domestic. Gene ontology (GO) is a major bioinformatics initiative, whereby descriptions of gene products across the database are developed and unified to describe all species. This process is performed by biocurators, who gather, annotate, and validate information on the databases, consequently affording easy access to accurate and updated data. In this study, we investigated the biocuration of two biological processes, DNA integration, which is used for DNA coding, and the tricarboxylic acid (TCA) …

The hydrogen bond plays a vital role in many reactions. This study is to investigate the effect of different hydrogen bonding modes, such as single and double hydrogen bonds, via the quantum mechanic (QM) methods. Four histidine models (A, B, C, and D) with different numbers of intra-molecular hydrogen bonds were studied. The QM model results indicate that the double hydrogen bond is plausible and has a more stable geometry. However, this study suggests that the data from QM methods require further evaluation with solvation models to produce an even better energy profile.

Economic Potential Of Okra Cultivation For Limited Resource Farmers, Phillip Harris, Eric Obeng, Aruna Weerasooriya, Peter Ampim
Economic Potential Of Okra Cultivation For Limited Resource Farmers, Phillip Harris, Eric Obeng, Aruna Weerasooriya, Peter Ampim
Pursue: Undergraduate Research Journal
Background: Okra (Abelmoschus esculentus L. Moench), is an economically important vegetable crop with a potential to increase farm incomes of small producers. This is because okra is popular, easy to grow, and valuable with average retail prices of up to $7.07/kg. In Texas, research has shown that diversification of farm operations boosts income and farm sustainability. Hence, exposing farmers to economically important crops that are not typically grown is necessary. Production success is linked to crop variety choices. As result, the objective of this study was to evaluate the performance of multiple varieties of okra (Red Burgundy, Jambalaya, Zarah and …

Spatial Variability Of Manganese Oxide In Two Soilscapes: Upland-Lowland, And Riparian Buffer-Wetland Boundary- Wetland, Benjamin Onweni, Richard Griffin, Robert Thomas, Edward Timms, Javon Polk, Annette James
Pursue: Undergraduate Research Journal
Background: This research project describes the development
of a quantitative measurement methodology to determine the
concentration of manganese oxide (MnOx) in two soilscape
positions (Upland- Lowland and Riparian Buffer-Wetland
Boundary-Wetland). Methods: A reaction between the MnOx
in the soil sample and hydrogen peroxide (H2O2) was initiated
to determine the level of MnOx reactivity in the soil sample. Data
was collected from four sites on Soilscape 1 (Upland, Lowland,
and two sites between the Uplands and Lowlands); within each
site, five soil profile depths and three sample replicates were
measured which comprised a total of 60 samples. Additionally,
data was collected …
