Our goal has been to develop a compartmental model of vitamin B-6 metabolism which can respond appropriately to a variety of conditions using data from the literature. Modeling vitamin B-6 metabolism is challenging because vitamin B-6 is interconverted between 7 common forms: pyridoxine, pyridoxine 5u27-phosphate, pyridoxal, pyridoxal 5u27-phosphate, pyridoxamine, pyridoxamine 5u27-phosphate and 4-pyridoxic acid. In addition, in humans 5-pyridoxic acid becomes a significant metabolite with high vitamin B-6 intakes. Development of the model utilized the Simulation, Analysis and Modeling (SAAM) software originally developed at NIH and now available as WinSAAM(http://www.winsaam.org/) and SAAM II (https://tegvirginia.com/solutions/saam-ii/). The model is designed to achieve a steady state before changes are introduced. We found that several characteristics were required in the model. Because plasma values fluctuate with meal intake, the model needed to reflect meal intake. Because experimental data reveals flushing effects, at least some pool sizes must have limits to generate flushing. Because reducing intake has limited effect on the vitamin B-6 content of muscle, which accounts for about 70% of the body pool, there must be a mechanism to conserve vitamin B-6. Models provide a method of simulating various situations. In the case of vitamin B-6 this model can be used to estimate turnover rates, the effect of changes in intake on body pools, and the role of erythrocytes in vitamin B-6 metabolism. The model can also be used to determine optimal sampling times for proposed experiments. It can easily be updated as new data become available. We are still working to improve the fit of the model to various data sets. We also hope to add more data on circulation and additional tissues

We establish elliptic regularity for nonlinear inhomogeneous Cauchy-Riemann equations under minimal assumptions, and give a counterexample in a borderline case. In some cases where the inhomogeneous term has a separable factorization, the solution set can be explicitly calculated. The methods also give local parametric formulas for pseudoholomorphic curves with respect to some continuous almost complex structures

Absolute population size has been proposed as one factor that encourages terrorism since large states have more difficulty maintaining security. More populous states suffer from more terrorism because they have more people, but the relationship disappears when per capita measures of terrorism are used. There are some indications that smaller states are more secure, but the evidence is not consistently present

A longitudinal study examines the correlation between social networking behaviors and romantic relationship variables. Rather than being harmful to relationships, analysis indicates that most behaviors are reflections of the relationship’s current state. Flirtation and public praise are exceptions, with the former diminishing relationships, and the latter enhancing

The force of attraction between any two objects in the universe is related to the mass of each object and the distance between the objects multiplied by a proportionality factor, G. We measure the universal gravitational constant using a torsion balance with two pairs of metal masses, one small and one large. Attaching a mirror to the pendulum bob and using a laser projected from the mirror allows us to measure the angular twist of the torsion ribbon in response to the attraction between the large and small masses on either side of the pendulum. We used three different methods of using the pendulum to calculate this constant. Each of the three methods yielded values of G: GI = 6.41 ± 0.05 x 10-11, GII = 6.36 ± 0.04 x 10-11, and GIII = 7.8 ± 0.1 x 10-11

A pair of POCOP-supported mono- and dicarbonyl complexes of Co have been prepared and crystallographically characterized. The reactivity of (tBuPOCOP)Co(CO) with H2, acids, and carbon monoxide has been compared to that of the previously reported Rh and Ir counterparts. Co is found to share reactivity traits with both Rh and Ir

The animal microbiome has rapidly become of great interest in current research as the microbiome is considered to be of vital importance to the survival of its host. Most studies have focused on bacterial communities due to their large populations and their smaller genomes. However, there are other understudied groups, such as fungi, which may also be important to improving our knowledge of their roles with their hosts. In this study we aim to identify the fungal communities within the cloaca of green sea turtles (Chelonia mydas) with the secondary goal of discovering whether these communities vary by ontogenetic shift in habitat. Pelagic-stage turtles were sampled from the Port of Venice, Louisiana while neritic juveniles were sampled from along the beachfront of Santa Rosa Island, Florida. Cloacal swabs were collected and stored at –20˚C until DNA extraction. The fungal ITS regions were amplified using PCR and cloned into the pGEM-T vector for selection and sequencing. Samples from six individual turtles resulted in 30 clones which show that the majority of the fungal communities in the cloaca are dominated by the phylum Ascomycota, which includes the genera Candida, Cladosporium, Podospora, and Epicoccum. Other fungi identified include strains of Exophiala and Malassezia. The overall fungal community of the cloaca is primarily dominated by cellulolytic fungi, especially in the neritic sea turtles. A majority of the fungi identified are common on the dermis of animals, while others, such as Epicoccum nigrum, may even have some antimicrobial properties to aid the host in avoiding pathogens. At present, and to the best of our knowledge, there have been no other studies made in an attempt to characterize and identify the mycobiome of healthy, juvenile green sea turtleshttp://opus.ipfw.edu/stu_symp2017/1013/thumbnail.jp

In light of recent scholarship about teachers leveraging social media to support their continuing professional development, this article documents an investigation of school board policies governing teachers’ use of social media. Focusing on 30 traditional public school systems within a 10-county region in the Midwestern United States, the author collected social media policies and conducted an ethnographic content analysis to build an understanding of the policies that stand to guide teachers’ professionally oriented participation online. Of the 30 public school districts included in the study, 19 districts published policies specific to teachers’ use of social media. Reporting the study’s findings, the author addresses the districts’ efforts to craft policies that define social media, reiterate relevant pre-existing policies and support educational uses of social media. Implications for teachers, teacher educators and policymakers are included

The type of response (text based, emoticon based, or none at all) to a negative text message was assessed. Participants preferred text based, over emoticon based, over no response. Personality factors related to these preferences were also assessed. Thoughtful written responses appear to be the preferred way to communicate support

It is widely accepted that by 2050 the world will host 9 billion people. Today’s society already copes with nearly 1 billion chronically hungry people worldwide; factoring climate change effects and subsequent alterations in geology, there will be devastating effects on food sources. We need to find new ways of growing food and rediscover our original diets as Homo-sapiens. An insectivorous diet is able to provide essential proteins and nutrients to the human body. Insect consumption also offers a significant opportunity to merge traditional knowledge and modern science in both developed and developing countries. Placing insects back into the human diet will allow alternative nutrition, a healthier environment, and increased trade and economic development. This paper contains two surveys conducted in the hope of raising awareness of the many valuable roles that insects play in sustaining nature and in human life. The first survey, with 100 responses, sheds light on the misperceptions people have when considering eating insects. In the end, 39 of the 100 responses would choose insect diets over beef. The second survey of 200 responses gives the respondents nutritional, environmental, and geographical facts about insects before leading into questions in response to the facts given. Based on the second survey conducted, 88% of 200 respondents are more willing to try insects and believe in the changes that could happen globally if the insect diet were embraced. From the two surveys, it appears people are more willing to try insects after they have been presented with the relevant nutritional and environmental incentives. All it takes is education/ and exposure to change people’s perceptions.http://opus.ipfw.edu/stu_symp2017/1031/thumbnail.jp

Thrips are economically damaging plant pests. Not only does the thrips feeding on crops cause damage but they also serve as vectors for plant diseases such as tospoviruses. These viruses cause diseases that damage crops and lead to severe yield loss around the world. Studies with tospovirus, Tomato Spotted Wilt Virus have shown that virus infection changes the feeding behavior of thrips, causing them to probe three times as often as uninfected thrips. The tospovirus, Soybean Vein Necrosis Virus is an emerging disease that is vectored by soybean thrips (Neohydatothrips variabilis). The objective of this study is to determine whether infection with SVNV causes changes in the feeding behavior of the soybean thrips vector. The feeding behaviors of thrips, either infected or uninfected with SVNV, are monitored using the electrical penetration graph (EPG) technique. Electrical penetration graphs (EPGs) record electrical signals or waveforms when mouthparts of piercing-sucking insects, such as thrips, probe into a plant. Different feeding activities produce different waveforms, which can be analyzed to determine insect feeding patterns. Our results show that feeding behavior of infected thrips is significantly different compared to uninfected thrips. It is found that the most common probe type for the infected thrips was non-ingestion probes. Non-ingestion probes not beneficial for the thrips because they not ingesting the cell content. However, non-ingestion probes are beneficial for the virus because they allow the virus to be transferred. These results emphasize the coordinated evolution between topsoviruses and their thrips vector.http://opus.ipfw.edu/stu_symp2017/1024/thumbnail.jp

Our society faces a large amount of fear and emotions surrounding the ideology of death. The intent of my project is to create a way that we as a society can come to understand the importance of better expressing our views on death and its relationship in the life cycle. My project is an effort to answer questions concerning death and create a means in which we can all more fully understand how to cope with the aspect of the life cycle. The process and product I will be creating to address the issue of death and the life cycle, will be to create a company that will promote and produce end of life celebrations for individuals. My company, “Bucket Party”, will work with individuals and families to create a celebration of life party that will take place while a person is still alive. This will allow the individual a chance to gather with family and friends to celebrate and reflect upon their life. By doing this, I hope to show that by celebrating an individual’s life and accomplishments, they can better come to terms with the end of life. I have already hosted one such party and the results and impact were profound. I hosted a Bucket party for a military veteran who was dying of cancer. Family, friends and loved ones gathered together to celebrate the life and accomplishments of this individual. Doing this prior to death is a unique and profound way to celebrate life and come to terms with mortality.http://opus.ipfw.edu/stu_symp2017/1016/thumbnail.jp

Social media provides one route to behaviors that may be potentially harmful to romantic relationships, such as communicating with alternative partners, which can sometimes create relationship conflict, breakups, or divorce. Limited empirical evidence exists concerning social media infidelity-related behaviors and marital relationships. This study examined whether married/cohabiting individuals are using social media sites to engage in online infidelity-related behaviors and to what extent this related to relationship satisfaction, ambivalence, and relational attachment characteristics as reported by 338 married/cohabiting individuals from 176 families. Only a small percentage of married/cohabiting couples reported engaging in social media infidelity-related behaviors; however, more engagement in infidelity-related behaviors on social media was significantly related to lower relationship satisfaction, higher relationship ambivalence, and greater attachment avoidance and anxiety in both women and men. Additionally, attachment anxiety and gender interacted with relationship satisfaction in predicting online infidelity-related behaviors when controlling for other variables. Implications are discussed
